hello, this is breakfast, with charlie stayt and naga munchetty. obesity threatens to overtake smoking as the number one preventable cause of cancer. a major study suggests that nearly 40% of all cancer cases could be avoided if people adopted healthier lifestyles. good morning, it's friday the 23rd of march. also this morning: the eu withdraws its ambassador to russia in support of theresa may as the police officer exposed to nerve agent in salisbury says his life will never be the same again. on the brink of a trade war. china hits back at president trump with plans for big tariffs on us imports. after a week of revelations about facebook, i'm looking at what's hidden in the terms and conditions we all agree to but never read. in the wake of the facebook data scandal, just how much do we know

about the terms and conditions of the websites and apps we sign up to? and have you got yours? the royal wedding invitations are in the post. harry and meghan reveal the dress code for their big day. it is sport relief day today, this is the scene outside our studios at media city in salford transferred, transformed into a mini five a side stadium, huge numbers of events through the day and we will have coverage through the morning. through the day and we will have coverage through the morningm through the day and we will have coverage through the morning. is the weather fit for sport? and matt has the weather. not a bad day, we got rid of rain in scotla nd not a bad day, we got rid of rain in scotland and eastern england but a day of sunshine and a few showers. details on that and your full weekend forecast in about 15 minutes. see you then, matt. good morning. first, our main story. nearly 40% of all cancers diagnosed in the uk every year could be avoided if people adopted a healthier lifestyle, that's more than 135,000 cases. the study conducted by cancer research uk also warns that obesity could overtake smoking as the biggest cause of the disease. here's more from our

health correspondent, dominic hughes. exercise is now an important part of caffe beddington‘s life, but that hasn't always been the case. this was a couple of months after i had my operation. in 2014 she was diagnosed with cancer of the womb. shall never know for sure but can felt the extra weight she was carrying was a factor so she decided she needed to make changes in her life. i've got six grandchildren so to be around for them, to be around for my children, they bring such a lot of joy and for my children, they bring such a lot ofjoy and the thought of not being able to grow up alongside them and see them achieving what they wa nt to and see them achieving what they want to achieve, itjust made sense to do something. the latest data on cancer shows that smoking is responsible for more than 54,000 cancer cases each year. 22,000 people are diagnosed with 13 types of cancer linked to obesity.

skin cancer, caused by too much ultraviolet radiation from the sun 01’ ultraviolet radiation from the sun or sunbeds, sex more than 13,000 people. would hope or sunbeds, sex more than 13,000 people. would hope we or sunbeds, sex more than 13,000 people. would hope we would or sunbeds, sex more than 13,000 people. would hope we would continue or sunbeds, sex more than 13,000 people. would hope we would continue to or sunbeds, sex more than 13,000 people. would hope we would continue to see or sunbeds, sex more than 13,000 people. would hope we would continue to see smoking or sunbeds, sex more than 13,000 people. would hope we would continue to see smoking rates or sunbeds, sex more than 13,000 people. would hope we would continue to see smoking rates coming or sunbeds, sex more than 13,000 people. would hope we would continue to see smoking rates coming down, or sunbeds, sex more than 13,000 people. would hope we would continue to see smoking rates coming down, they or sunbeds, sex more than 13,000 people. would hope we would continue to see smoking rates coming down, they have been coming down at around 1% per year, so hopefully that trend would continue, if not accelerate. sadly we're not yet seeing the turnaround in obesity related activity yet or obesity related cancer, so clearly the expectation would be if we did this again in seven years time we would see those two getting closer together as risk factors for cancer. a healthy diet and more exercise have left cat feeling better than ever. today's report is further evidence that following catheter‘s example could reduce the risk of cancerfor all of us. example could reduce the risk of cancer for all of us. dominic hughes, bbc news. the european union has taken the rare step of recalling its ambassador to russia following the nerve agent attack in salisbury. it's being seen as a show of solidarity with britain after eu leaders agreed it was highly likely that moscow was responsible

for the poisoning. ben ando reports. in brussels, the prime minister is asking for solidarity, not separation. and after a working dinner last night, the eu answered by withdrawing its envoy to moscow. in the words of one diplomat, "for consultations". it is a threat to our values, and it is right that here in the eu council, we are standing together to uphold those values. earlier at a press conference, the message hadn't been quite as decisive. we will discuss the salisbury attack during our working dinner, and we'll be ready to... to answer more precisely. later in a tweet eu council president mr tusk tweeted: sergei skripal and his daughter, remain critically

ill, but police officer nick bailey, who was poisoned as he went to their assistance, has been sent home from hospital. nick has had to undergo significant medical treatment, which is undoubtedly been very daunting for him and for his family. i have personally been amazed at the strength and resilience of nick. in brussels the prime minister seems to have convinced britain's european allies to stand strong on russia. later today they'll be talking brexit, where she may be hoping for a softer approach. ben an, bbc news. damian grammaticus is in brussels for us this morning. yesterday theresa may was on a charm offensive trying to get people on her side, today she's almost going to be out of the meetings for a while because brexit comes back on the agenda? exactly, when the brexit portion of discussions happen today,

theresa may will not be in the room. she's only stayed on today because eu leaders were waiting for news from washington about tariffs on steel and aluminium. that news that the eu will be exempted didn't come through until very late, she will stay here while eu leaders discuss their response to that. what she was able to do is discuss the salisbury incident and get this strong statement of support from the eu, who said in their conclusions yesterday that they condemn in the strongest possible terms the recent attack in salisbury and the eu now has taken the unusual and surprising step of saying it's going to recall its ambassador to moscow for a few weeks, we believe, for consultations. the brexit talks that things will move onto today are crucial for the things will move onto today are crucialfor the uk. things will move onto today are crucial for the uk. two things will move onto today are crucialfor the uk. two reasons, first of all eu leaders should give their consent to the outlines of that withdrawal and transition agreement that's being discussed, that would be good news for the uk.

the second thing is all so there is expected to give their consent to the go—ahead for talks to begin about the future relationship and to give a broad outline of the eu goals for those talks. so both things would mark an important step forward. indeed, thanks bromance, damian grammaticas. —— thanks very much. president trump has sacked his national security advisor for the second time in 14 months. general hr mcmaster will be replaced by the john bolton. he has previously served as america's envoy to the un and has backed carrying out attacks on iran and north korea. china says it's disappointed by president trump's announcement that he plans to impose tariffs worth tens of billions of pounds on chinese imports. the white house said the duties were necessary and a retaliation for years of unfair competition from beijing. 0ur china correspondent stephen mcdonelljoins us live from hong kong. good morning. tell us more about the

chinese reaction. well, the most recent thing we're hearing is from the chinese commerce ministry spokesperson, who says china won't sit silently by, that it's prepared to do what it has to to defend its own interests, that china doesn't wa nt own interests, that china doesn't want a trade war, but nor is it afraid of one. this comes after china announced a series of its own ta riffs china announced a series of its own tariffs that it will place on the us if the us goes through with its threats. before i tell you what those are on, i should stress this is in response to the first round of ta riffs is in response to the first round of tariffs announced by the trump administration, not the most recent ones. we're already getting a threat from china to have tariffs on american fruit, nuts, from china to have tariffs on americanfruit, nuts, ginseng, steel pipes, pork. this will hit some american farmers who have supported donald trump, so there could be a

political element to that. stephen, i'm going to interrupt you ifi stephen, i'm going to interrupt you if i may, we got one or two problems with the sound in hong kong. we will come back to you later but apologies for the problems with the sound there. that is around the chinese disappointment over... this is their statement, they are disappointed about donald trump's announcement of those new caris. 150 whales have become stranded on a beach in western australia. fishermen spotted the short—finned pilot whales at hamelin bay near perth early this morning. conservationists say at least of half of them have died. bad weather conditions are hampering efforts to rescue the surviving animals and move them back out to sea. the authorities have also issued a shark alert, warning people to stay away from the area. mps said proposals for a third ru nway mps said proposals for a third runway at heathrow airport shouldn't be approved without noise level

appreciation. victoria fritz has the details. it would be one of the biggest privately financed infrastructure projects anywhere in the world, but the transport select committee says there's no guarantee that passengers at heathrow wouldn't pay the price of building a new runway. heathrow‘s airport charges are the highest in the world — mps are concerned that they could rise if the project were to run over budget. that would mean fewer passengers could afford the fares and fewer airlines could afford to land at heathrow. airlines like british airways have already urged mps to make a freeze on charges a condition for approving the plans. airlines like british airways have already urged mps to make a freeze on charges a condition for approving the plans. what the government and the airport are both saying is that they anticipate that this very costly scheme shouldn't result in any increase in the real level of airport charges, and what the committee are saying is that's the right ambition to have

but we want to be sure that you've got plans in place to deliver it. more information on costs and charges, air quality and noise are needed, the committee says, to protect the interests of passengers and the well—being of local communities. if the scheme goes ahead, over half a million people are likely to be under or near the flight path by 2030. the government will now be expected to respond to the committee, before the final plan is put to parliament for a vote injuly. victoria fritz, bbc news. have you got yours yet? we know the invitations are in the post. prince harry and meghan markle's invitations have been sent out for their wedding. markle's invitations have been sent out fortheirwedding. some markle's invitations have been sent out for their wedding. some are going to be on some doormats as well. this is what they looked like. they have been made using american on english card. —— american inc. they are printed by a company called

barnard and westwood. the couple have invited 600 guests, with a further 200 invited to the reception. lottie small is the name printer, who had recently finished her apprenticeship, and was given the opportunity to make the invites. she used the machine, which she nicknamed maude, to print every invitation. the invites reveal the dress code for guests attending the ceremony is uniform, morning coat or lounge suit, or day dress with a hat. the invitations are similar to the ones sent out for the william and kate's wedding in 2011, although these were in a different font and were issued with the queen's royal cipher. this is a lounge suit, isn't it? what i'm wearing? i think it would be ok. you are ok, the invitations are similarto be ok. you are ok, the invitations are similar to william and kate's wedding in 2011, but they were in a different font and had the royal cypher. you have all the information you need. unless you already have an invitation and it was pointless but if you didn't know... it's sport relief today, and there's lots going on here at media city in salford.

there's a zip wire you could take pa rt there's a zip wire you could take part in later today and you could zorb. thank you. stuff to do after we finish work! john is in the thick of it. 0n the pitch, keeping on terra firma for now may be? good morning to you both. we are here, plenty of against being staged at media city today, this is the penalty shootout pitch where the former republican of island goalkeeper shay given will face 12 hours worth of penalties in a row. a marathon penalty shootout. —— republic of ireland. robbie savage has a team of celebrity friends on the five aside pitch, they will take on teams from the fa people's cup for 12 hours, most events starting at 11am so if you can come down then it's well worth it. plenty of sport to tell you about this morning. after england's embarrasing first—innings in the opening test against new zealand in auckland, rain has now intervened. the home side were 229—4

when they were forced off. despite three wickets forjimmy anderson, they are still 171 ahead. stuart broad court two wickets, anderson got two. we will see if play continues there. gareth bale becomes wales's leading all—time goal—scorer, a hat—trick in a 6—0 win against china takes him past ian rush‘s old record, in what was ryan gigg's first match as wales manager. england manager gareth southgate says he isn't worried about his players‘ safety at this summer's world cup. preparations begin with a friendly tonight against the netherlands, with another against italy on tuesday. and rory mcilroy is still in contention at the world matchplay golf in texas. after defeat on day one, he beatjhonattan vegas, so one more win would take him through to the knock—out stage. rory mcilroy, as we know, has had a

great start to the year so far. so plenty to bring you this morning, hopefully we will have some guests joining us, and as we know, it is a very worthy cause which has raised £330 million for charity since its launch. i will not be on my own, but will have many people joining launch. i will not be on my own, but will have many peoplejoining me. did someone take your ball away?|j know, did someone take your ball away?” know, i am did someone take your ball away?” know, iam missing did someone take your ball away?” know, i am missing one. did someone take your ball away?” know, iam missing one. it did someone take your ball away?” know, i am missing one. it is probably the best. my skills are not the best. i am waiting for you to join me later. we will be joining you ina join me later. we will be joining you in a little bit. and a slightly rubbish sound effect accompanying his shot. what would your sound effect be? it would be better than that. here is matt with a look at this morning's weather. good morning to you. if you are off

to any sports relief events, a lot of dry weather, but some wet weather around elsewhere which will ease the many of you. this is the satellite imagery for the night, cloud spilling from the atlantic, so it will not be desperately cold, but this big area of cloud has been bringing rain. to the south it is clearing, rain for the next hour or two in east anglia and the south—east than some sunny spells developing and one in order to make showers across wales. many places becoming dry and bright. for the morning rush hour a different story, lots of rain across scotland, the bulk of that pushing to the north and north—west through the morning. across northern ireland and southern scotla nd across northern ireland and southern scotland and the far north of england some heavy showers as we go through the rush—hour. so some of you will remain a little bit on the wet side. i think by the time we get to the end of the morning there will bea to the end of the morning there will be a few more showers across southern scotland, northern ireland and northern england. still pretty wet across the highlands and

ireland. gusty winds will gradually ease down, but a good deal of sunshine through the afternoon turning hazy for the england and wales. temperatures around 13 degrees in the south—east corner, nine or ten degrees in the south—east corner, nine 01’ ten across degrees in the south—east corner, nine or ten across scotland and northern ireland. 0ne nine or ten across scotland and northern ireland. one or two showers in scotland and northern ireland, they will ease. an area of low pressure spinning down into france will push up some rain and that will stop temperatures from dropping too much. with clear skies in scotland and northern ireland, there is your greatest chance for a frost, maybe down into —3 in parts of eastern scotland. a cool start the weekend, but overall a mild start. temperatures where they should be for the time of year, and if you have weekend plans a lot of dry weather to enjoy. 0f have weekend plans a lot of dry weather to enjoy. of the wettest weather to enjoy. of the wettest weather will be from cloud and drizzle lingering across parts of east anglia and the south—east into the afternoon. some showers in western scotland and northern ireland and the odd one elsewhere. lots of dry weather in between them, and at best the sunshine away from

that cloud in the south and with sunny spells could see temperatures peak around 11 or 12 celsius. in the sunday, a fresh start and frost around. a brighter day across the south, a milder day to come with those sunny spells. a few showers in northern england, northern ireland and more especially the north and north—west of scotland. with winds going north—westerly, a bit cooler on sunday, and the showers could be heavy at times with hail and thunder. 0n the very tops of the hill is a bit of sleet and snow as well. sunday the milder of the two days of the weekend, temperatures widely in double figures. 13 degrees the high end the south—east corner. don't get to it, because next week and in the run—up to easter it is set to get a bit colder as well. we all know how important dna is to understanding human health, but now scientists think it could be used to solve another global problem — data storage. it may sound odd, but all those videos and photographs we love to take could one day be stored in the form of dna, saving huge amounts

of space and energy. 0ur science correspondent richard westcott explains. we are producing data at a staggering rate. all those videos, social media posts, online forums, and "look where i am" selfies. the problem is it takes a huge amount of computer space and energy to store it all. so could the answer lie somewhere else, somewhere deep inside us all? i could not resist making a video of this beautiful replica of the famous watson and crick double—helix, the model of dna that changed the world. but what if i could store the video i am making now onto a piece of dna. we take the movie file you sent me, which on a computer is zeros and ones, and we convert that into a, c, g, and ts. this cambridge mathematician has devised a way of turning computer code into dna code. it means you can use the dna as a kind of hard drive.

tell us about the day when you came up with the idea. the day was a big meeting discussing how we were going to keep on storing large amount of information coming from experiments on dna. and in a lightbulb moment, we realised that the dna we'd been worrying about was itself a way of storing information. an american company turns nick's code into physical dna. it is a secret process, but they told us why it is so effective. so the first huge benefit of dna is that it is extremely dense. and if we stored all of the data that is on the internet in dna, that would be the size of a shoebox. and the second main benefit of dna is it's permanent. you can store it forever, which is very different from, a normal medium,

which ages very rapidly. back at the institute in cambridge, they are world leaders in reading dna. the big question, then — did it work? can you read it. we put it back together again and it is this file. there it is. it does not look like there any errors in it at all. no, and we checked, and it is a perfect copy of the file. every single zero and one is correct. big companies including microsoft are also looking at dna storage. it is still too expensive and too slow, but that could soon change. in five years it will be

advanced enough that, and perhaps 10—15 years before, there is a product that you and i would buy for personal use. richard westcott, bbc news, talking to you from a piece of dna. soi so i have a few questions. is the dna in liquid form? it basically comes in a powder, and they put it in solution so it is easier to transport. it makes it a bit bigger so transport. it makes it a bit bigger so that when you get it back to cambridge they can split it back to lots of little bits and read it separately. and because it is a physicalform, can separately. and because it is a physical form, can that not be changed? 0ne physical form, can that not be changed? one of the things that was mentioned was that electronically it can be destroyed. can you not destroy that power or change the composition of that powder? —— destroy that powder. you probably

could, like you could with a computer disk, you can break that as well. but it is quite easy to store this data, as long as it is quite chilly, —18 they talk about. i have extracted dna out of straw breeze, it is easy to do, you can do it with your kids. —— strawberries. and you just keep that in your fridge, and it is sort of a white substance on the top of the straw breeze, and thatis the top of the straw breeze, and that is the dna. so it is quite easy to store —— strawberries. that is the dna. so it is quite easy to store -- strawberries. so when we cast our minds into the future and how this might be used in practice, do people become the vessels within which all this material is stored? is that the vision? no, it is not the dna in humans. dna is part of human beings, of all living things, but this would be separately manufactured. so again, it is quite ha rd to manufactured. so again, it is quite hard to visualise, and we couldn't actually filmed the process in america. at what they actually do is they get the molecule that make up

dna and they have the pattern they have to follow, and they spray it almost like an inkjet printer, and thatis almost like an inkjet printer, and that is how they physically manufactured the dna. it is dna that they manufacture. so where would that be, physically? that stuff still has to exist somewhere, so where would it exist? my assumption is it would be a powder or something potentially inside something that you are shooting a film on, for example. they would find a way you can carry it around like they do a ha rd can carry it around like they do a hard drive at the moment, with the computer. a were talking about ten to 15 years. is that a realistic timescale, that we could start storing in that time?” timescale, that we could start storing in that time? i think because the process isn't as cheap as need it yet to be commercially viable, that is what they are aiming at. the problem is the writing part which happens in america, that is the bit that takes longer, and is expensive. the reading they are good at now. they have mobile dna readers you can take into the field. so you don't need the big machines. that is

what they are aiming at. as i said that, there was a big meeting in new york recently, all the people working on this, and when you have names like microsoft working on something like this it can push it forward very quickly. so this isn't a few scientists pottering away in a shared working this out, there are the people involved in this now. that is what they are hoping. you will be back a little later on. i guarantee people will have questions. brace yourself.” guarantee people will have questions. brace yourself. i had better start asking nick. it is a com pletely better start asking nick. it is a completely different way of talking about data. please get in touch —— asking nick. john is in bristol for us this morning at a new museum celebrating a man who some say built britain, isambard kingdom brunel. good morning to you. 25 september... in london, creation, obviously, of the renowned offices in london. he liked to think of himself not only

as an engineer, but the first engineer. his competence are absolutely extraordinary when you think about the ships and bridges he built. you can just think about the ships and bridges he built. you canjust imagine him sitting here in his office, ruminating, creating suspension bridges, the ss great britain which sits outside, his famous cigar, perhaps a glass of port next door. this watercolour painted by his niece is you an idea of the painter had gone with this brand ‘s new museum to create parts of his life. we will do now what he has done for the rest of us, and that is take us from london to bristol. looking here into the clerk's office, re—creating all kinds of top hats, this is where they would have drawn all the extraordinary pictures of the ships. the ss great britain sits just outside. we can show you some of the original rooms, the white buildings to the right of the great britain,

where a lot of this work will have been done. we are going into william paterson's office, and this window is recreating what bristol would have looked like at the time in the victorian era when all of these extraordinary creations and innovations were being built. we will show you so much more during brea kfast will show you so much more during breakfast this morning after the news, travel and weather where you are. good morning from bbc london news. i'm tolu adeoye. at least nine people have been fatally stabbed or shot in london within the last week, and today public health officials will gather at city hall to discuss knife crime in the capital. the mayor, sadiq khan, wants to work with 0fsted to educate young people in schools. the home office has also launched a new social media campaign to reduce knife crime amongst young people. the met has apologised after two officers took a selfie at a murder scene and posted it on twitter. officers from newham took the photo outside the stratford centre on thursday, where a man had been fatally stabbed two days before. a spokesman said the officers showed a lack ofjudgement and sensitivity. the government has announced

a change in the law to help businesses affected by terror attacks. it will allow insurance claims, even if property hasn't been directly damaged. it means shops like those inside borough market, whose businesses were behind a police cordon for an extended period of time after last year's terror attack, could in future be protected. rates of tuberculosis in london have dropped by 41% in the last five years. public health england says the fall is partly due to increased screening for tb, but the capital still has the highest rates for the disease in the country. a new exhibition is highlighting the history of digging under london. it will look at tunnelling beneath the capital from the early 19th century right up to crossrail. it opens at the london transport museum today. let's have a look at the travel situation now. there are severe delays on the district line between wimbledon and edgware road. a good service on all other lines. on to the trains: there

are cancellations on hull trains into kings cross, and that is due to a lack of available trains. a13 is slow moving from dagenham to barking. the usual delays there. the a501 marylebone road near baker street has a lane closed in both directions. that's for roadworks. let's have a check on the weather now, with elizabeth rizzini. hello, good morning. once again it isa hello, good morning. once again it is a frost free start to the day. with temperatures between five and eight celsius but a pretty disappointing early start. it is cloudy and it is damp that should shape up to be a fairly decent day of weather and we will see some good spells of sunshine around. these we re spells of sunshine around. these were gradually lighten. so a weather front is moving its way eastwards. by front is moving its way eastwards. by the time you to the end of the morning rush hour it should have gone and the sky that will brighten behind it. we will see some good spells of sunshine develop. just a

small chance of one or two isolated showers through the afternoon but most of us are likely to stay dry. the sunshine turning a bit hazy with the arrival of more high of it later on through the day. top temperatures 12 or 13 celsius. now through this evening and overnight it is likely to be frost free. but as you can see we are likely to see some outbreaks of rain. it will be quite light and patchy into tomorrow morning. a lot of cloud, lows of four or five celsius. over the weekend we are keeping that cloud on saturday. began some outbreaks of light, patchy rain or drizzle. don't forget the clocks spring forward one hour on sunday morning, sunday the nice day, with lots of sunshine and highs of 13 degrees. i'm back with the latest from bbc london in half an hour. plenty more on our website at the usual address. now, though, it's back to charlie and naga. hello, this is breakfast with charlie stayt and naga munchetty. we'll bring you all the latest news and sport in a moment, but also on breakfast this morning: as we hear how certain lifestyle choices can lead to cancer, we'll speak to one survivor who's transformed his life to reduce the risks, and feels better than ever. is using a calculator

in maths lessons cheating? well, new evidence suggests it may actually help pupils with their problem solving skills. we'll find out how, in our latest look at how the subject's taught in our schools. and we're zorbing and zip—wiring for sport relief this morning. it's the big day when thousands of us get active to raise millions of pounds for good causes. good morning, here's a summary of today's main stories from bbc news. nearly 40% of all cancers diagnosed in the uk could be avoided if people adopted a healthier lifestyle, according to a new study. cancer research uk says 135,000 cases every year are preventable. the charity is also warning that obesity could eventually overtake smoking as the biggest cause of the disease. the european union has taken the rare step of recalling its ambassador to russia following the nerve agent attack in salisbury.

the show of solidarity with britain comes after eu leaders, meeting at a summit in brussels, agreed it was highly likely that moscow was responsible for the poisoning. theresa may has delayed her departure from the summit to attend talks on trade and us tariffs. the threat russia opposes respect snowboarders and it is a threat to oui’ snowboarders and it is a threat to our values, and it is right that here in the eu council we are standing together to uphold those values —— —— respects no borders. president trump has sacked his national security advisor for the second time in 14 months. general hr mcmaster will be replaced by the john bolton. he has previously served as america's envoy to the un and has backed carrying out attacks on iran and north korea. using calculators in maths lessons can boost pupils‘ problem—solving skills, but they need to be used alongside mental arithmetic. that's according to a report by a charity, the education endowment foundation.

it also found that primary school pupils should use calculators less often than secondary school students. have you got yours yet? invitations to prince harry and meghan markle's wedding have been sent out. they've been made by barnard and westwood, using american ink on english card. you can see lottie small there, who had recently finished her apprenticeship with the printers and was given the opportunity to make the invites. she used the machine, which she nicknamed maude, to print every invitation. the couple have invited 600 guests, with a further 200 invited to the reception. those are the main stories this morning. let's talk about this fundraiser. it's the fundraiser that sees the uk's biggest sports stars and celebrities battle it out in their finest lycra to raise money for charity. and tonight, for the first time, the sport relief show will be live from media city in salford quays. john is outside for us now, where things are starting to happen.

a little lonely right now but it's going to be a busy day? it will be, a very busy day, loads of events going on today on the piazza. i'm on the 5 live footy pitch at the moment where robbie savage and a team of his celebrity friends will be taking pa rt his celebrity friends will be taking part in12 his celebrity friends will be taking part in 12 hours of five aside matches later. over their there's going to be a penalty shootout with the reformer republic of ireland goalkeeper shay given will face continuous penalties for another 12 hours. —— the former. most hours. —— the former. m ost eve nts hours. —— the former. most events kicking off at 11am, it's all part of sport relief, staged and hosted at media city tonight, over £30 million has been raised by sport relief since it was conceived in 2002. let's start with the cricket today. only place to start after the

abysmal performance from england yesterday morning. to england's cricketers, and what chance of them restoring some pride, at least, after that dreadful start to the first test against new zealand? well, not much at the moment. the home side had extended their lead to 171 when play was interrupted by rain, three wickets forjimmy anderson. new zealand now 229—4. gareth bale is now wales' record goal—scorer thanks to a hat—trick in a friendly against china. it was a spectacular debut for new manager ryan giggs, with wales dominating the match in nanning, 6—0 it finished, and bale has 29 goals to his name, breaking ian rush‘s record. it's amazing. i think on my

daughter's birthday today, so obviously happy birthday to her, obviously happy birthday to her, obviously disappointed i can't be with her but it's great individually to get the record, but, as i say, the most important thing is always the most important thing is always the team played as well and under a new manager it's important to get off toa new manager it's important to get off to a good start. what a way to impress your new manager! england manager gareth southgate says he has no concerns about security and safety at this summer's world cup in russia. but even though he believes the atmosphere will be good in the stadiums, he suspects the england team won't be anyone's favourites. uk government ministers and members of the royal family won't be attending the tournament, which sta rts attending the tournament, which starts in mid—june. i don't think we're going to be the most popular the way things are going at the moment, but maybe that's something we've been used to over my career with different teams. maybe that can be some extra motivation for us. rory mcilroy can still reach the last 16 of golf‘s world matchplay in austin, texas after losing on day one, he beatjhonattan vegas, so he needs one more group win to make it through. and british gymnast

alice kinsella has won herfirst senior medal, bronze in the all—around event at the world cup in birmingham. she's only 17, and she said it had really lifted her confidence ahead of next month's commonwealth games. we don't have any gymnasts down here for sport relief later but we do have one of our greatest olympians coman nicola adams emoji won back—to—back golds, she will be here because she's commentating on celebrity boxing, one of the main events at sport relief tonight —— greatest olympians, nicola adams, she won back—to—back golds. most she won back—to—back golds. m ost eve nts she won back—to—back golds. most events kicking off at 11am with the football and penalty shootout. we have a zip wire, there is all being, its all going on down here today and if you can't get involved you can download the sport relief at

and you can count your steps through the day and they are hoping to get the day and they are hoping to get the whole nation to achieve 1 billion steps today. if you can't get down here that's one thing you can do to support sport relief. john, it wasn't missed, you're very nonchalant keepie uppie business at the beginning of the sport, you just threw that in the mix. go on, i want to see some more. i thought i would quit while i was ahead, charlie, five is about my limit! i thought perhaps... oh, ahead, charlie, five is about my limit! ithought perhaps... oh, no, now he's put the pressure on! he will be keeping it going for the next hour and we will be back with john later. he is so good! always goes wrong in the end if you stay long enough! we will have the weather for you across the uk coming up weather for you across the uk coming upa weather for you across the uk coming up a little bit later on. nearly 40% of all cancers could be prevented by adopting a healthier lifestyle. that's more than a 135,000 thousand cases every year. it's according to a study by cancer research uk which says obesity could soon overtake smoking

as the biggest killer. andrew renehan is a professor of cancer studies at the christie nhs foundation trust and joins us now. sport relief is all about people taking more exercise, this report is pulling together information that's been gathered recently about obesity. take us through the findings. this is an updated report that links the population of the uk and cancer incidence with a variety of lifestyle factors. it's updated from 2011 to this year. the key message is twofold. the biggest cause of cancer is smoking, but fortu nately cause of cancer is smoking, but fortunately it's on the way down. but the black are news is that the second commonest cause of cancer is obesity, and that's on the way up, and that's a real concern for public health england and cancer research uk --

health england and cancer research uk —— blacker. health england and cancer research uk -- blacker. the other day i heard a radio advert about this and it seems that's being ramped up in terms of getting the public aware that obesity is now the new target. it seems the message has sunk in with smoking, is that their? that's afair with smoking, is that their? that's a fair assessment. researchers like myself have known this for over a decade —— is that fair? doctors have had it on the radarfor the last five or six years but the public are still behind on this, there's a lot of surveys that show there's a lot of surveys that show there's a lot of surveys that show there's a real lack of awareness of this risk factor and its importance. can you go through some of the basic squirrel why does being obese cause cancer? 0k. squirrel why does being obese cause cancer? ok. we don't fully understand this but we think it is due to two big areas. when we are of these there's things in our circulation related to hormones and inflammatory changes, which probably make it more susceptible to developing the cancer —— when we are

obese. the second area is around the cancers themselves, if we develop a lot of fat around where the cancer is starting to develop, these are also changes that favoured cancer cells growing. why do people there and who are very fit, who lead really good lifestyles, don't smoke and drink excessively, why do they get cancer? cancer research uk have been clear on this, there's people who do the right things but still u nfortu nately who do the right things but still unfortunately developed this. who do the right things but still unfortunately developed thism there a statistic? research is saying 40% of all cases are caused by obesity, is there a statistic that looks at the number of healthy, or deemed healthy people, who have cancer? the 40% refers to not only obesity, it refers to all of these lifestyle factors. smoking, obesity, alcohol, certain dietary things, and they also include uv light and radiation,

which has also come up on the radio. there's statistics for each one of those —— radar. perception is important in terms of changing habits, do people link being overweight and obesity with other conditions, their heart, they think about their fitness levels, but they don't link it to cancer? absolutely, and even on the school curriculum at the moment there's a question in the science curricula that links it with heart disease and diabetes, but even the teachers don't link it with cancer. this is clearly something we need to get out there even at a young age and into young adulthood, because that's when it's really important. how long do you think it will take to get the message out? we mention how smoking is finally sinking in, people now associating that with bad health and avoiding smoking, how long will it ta ke to avoiding smoking, how long will it take to sink in? there's great opportunities at the moment. the

fa ct opportunities at the moment. the fact we're on this programme this morning is fantastic, we have media out there, social media, this should be getting out there and having an immediate effect. clearly we know we area immediate effect. clearly we know we are a nation that has a real problem with obesity now, right now, so if you're one of those people in that category already, what are your chances of improving your life expectancy, the risk of getting cancer, by making a sudden change to your lifestyle and dropping your weight? that's a super question and there are two that's a super question and there a re two parts that's a super question and there are two parts there. clearly the first thing we'd quite like to do is avoid obesity and weight gain in the first place, that's why the message has got to get out to people in early adulthood. if you're already in that position? if you're already in that position? if you're already in that position, we have some evidence to show by reducing weight we are reducing our risks, that's an area of active research at the moment and we want to try to quantify that better. how quickly can you reduce your risk if you

change your lifestyle? you're absolutely right, this is over many yea rs. absolutely right, this is over many years. the obesity link with cancer is probably a lifetime exposure of yea rs or even is probably a lifetime exposure of years or even decades, so it has to bea years or even decades, so it has to be a sustained effort to reduce weightand... be a sustained effort to reduce weight and... what is the percentage change, are there statistics to say if you are obese and you change your lifestyle over two years, you are not obese, you change, you're not unhealthy, how much do you reduce your risk? by your risk? by bringing people down from overweight to normal weight again, we estimate, as i say this is still an area of research, we can probably get these numbers down by 10% or 20% depending on the cancer type. professor, very interesting to talk to you this morning. thank you very much. we actually have some double digits on the map this week, but not for long apparently. good morning, no, things will change next week but for the next few days, things will

be around average for the time of year. today, even if it looks grim outside the window, it is brightening up. sunny spells winning through for many and a few showers left later on. this morning's rain is courtesy of this cloud slowly nudging off the atlantic. it will delay the clearance of the rain from scotland, northern ireland, but the rain is now clearing away from parts of england and wales. over the next few hours, the east anglia and the south—east are a bit damp. skies brightening by the end of the morning rush—hour. a few showers in the wales by the end of the morning. heading further north, the rush—hour will be wet across parts of scotland, the heaviest rain pushing its way into parts of the north. a few splashes of rain across eastern parts of scotland but even through the morning, northern ireland, southern scotland and the far north of england can expect further heavy showers to take you through. they will turn light through the day, the rain becoming slightly less persistent across the highlands into the afternoon. further south, a lot of sunshine to take us into the afternoon across england and wales, showers fewer and further between.

this system developing waiting in the winds for the night, but as promised, double—figure temperatures on the map. 13 degrees in london, not quite so in scotland, northern ireland, you might just not quite so in scotland, northern ireland, you mightjust get to 10 degrees. one or two showers in northern ireland and southern scotla nd northern ireland and southern scotland into the night. a lot more cloud across england and wales, the weather system across the south—west pushes into france but is up cloud, rain, and keeps temperatures are for england and wales. in scotland and northern ireland, where you see the clear skies it will be a chilly start to the weekend. —3 in parts of scotland. after that chilly start an average weekend in store and if you have outdoor plans there will be a good deal of dry and bright weather around. some of the dampest conditions on saturday in southern counties of england in particular. patchy, light rain and drizzle. it the rain may linger across east anglia and the south—east. isolated showers elsewhere for england and wales, the greatest chance of a showerfor northern wales, the greatest chance of a shower for northern ireland and western scotland through saturday afternoon, some of those heavy with

thunder but temperatures creeping up relative to today. in the sunday, after a chilly start, a lot more sunshine around. the brighter day of the weekend, especially in the south. a few showers coming down on what will be a north—westerly breeze by this stage, the showers still heavy and thundery with hail across parts of scotland, turning to sleet and snow across higher ground. 10 degrees possible in glasgow and belfast, and maybe up a little bit on saturday's values towards southern parts of england and wales. 13 the high in london, the mid— 50s in fahrenheit. things turning colder as we go through next week, but let's worry about that next week. com pletely let's worry about that next week. completely agree, i am so pleased you finished on sunday this time. nina is here, asking just how much we know about the terms and conditions of the various websites and apps we sign up to. sometimes websites and apps we sign up to. when you sign up apps sometimes when you sign up to these apps you click through the terms and conditions without properly checking. as we have been hearing all week, the data of 50 million facebook users was collected and then used

to target them with political ads. facebook has apologised and said it will change the way it works. but how much do you know about what happens to your data, and do you actually care? we asked some students in salford. when you sign up to facebook, you are quite aware that your data can be used in certain ways. so i think it is about limiting what you put out there, and just being really aware. the information i have given facebook, what i have put in my profile and my form, it is no different than the information i would give a stranger in the streets. all i have a facebook is my name and e—mail address, it is information i would normally give anyone anyway, so i am not entirely worried about what they will do without. as a sort of social tool, i don't think it is going to be blowing over any time soon, because there is so much which is being

taken in by it that you can stuff like this will eventually be forgotten about and brushed under the rug. so i don't think it will damage it that much. everyone has my data. the government has my data, the banks have my data, i have nothing to hide. so i don't know why there is a sort of paranoia surrounding our data at the moment. when you sign up to websites like twitter and facebook and these are not secure websites, necessarily, what can you expect? martin bryant, technology expert, joins me now. first of all, let's establish, when we click through the terms and conditions, what are we saying yes to? it is how our information will be used, and key things to look for are how they can is value information, what information they collect about you, that kind of thing. we saw with those students, then, and! thing. we saw with those students, then, and i feel the thing. we saw with those students, then, and ifeel the same, slightly, is anyone bothered about my information? my holiday photos are pretty boring. why does it matter? that is the thing, people don't

really care, but it is really valuable information. that is for advertisers, but it is also, as we have seen with political targeting, people doing all kinds of research about the world. so really this is... people say data is the new oil, which some people may dispute, but data is certainly very valuable, and each individual person should really think about their data as a valuable resource. we are giving them freely to these companies. despite the fact we have seen alleged exploitation over the past week or so, delete facebook was trending on tuesday, and yet it has not had that much impact, has it? what will it take for people to really ca re ? what will it take for people to really care? i think the main problem is that facebook is so ingrained in people's lights, keeping people in touch with people around the world. for some people it is their only online presence. so i don't think facebook has a lot to worry about in terms of a mass exodus of users, because we wouldn't actually go anywhere. what would

really hit facebook more, and what they are worried about, is increased government regulation. and some advertisers putting it that way. some users saying that the algorithms expose you to things you might not otherwise have seen and in some ways they can be quite useful, when they use your data in that way. at the other side of this. a lot of people hate the idea of targeted advertising, but it can be actually very useful. if you switched off targeted advertising, the kinds of ads you would see would not be very nice. you would get... they would be generic, and i have done it sometimes, where i have been logged into something where i don't have my personal account tied to it, and you get really cheap, horrible advertising. so it can be preferable. so what should people do if they want to protect themselves a little bit at a? on facebook they have some privacy settings you can go into. they will be getting better very soon that some eu laws coming in. facebook is introducing a new privacy centre allowing you to very

easily delete your account and change its settings. and there is a guide to that on the bbc website. we have not left story forever, i can guarantee you that. he has been described as the man who built britain and helped shape the world. isambard kingdom brunel was responsible for the likes of the great western railway and the clifton suspension bridge. a new museum about the british engineer opens today in bristol, where you will be able step inside brunel‘s original office at the great western dockyard, where he created the ss great britain, and john maguire has been allowed in before it opens to the public. you are one fortunate man. a very, very lucky young boy today i am. here is the ss great britain, which sits here just here is the ss great britain, which sits herejust in here is the ss great britain, which sits here just in the floating harbour at bristol. and next door to it, this brand—new museum. and it gives you a real insight into... almost fell the wrong way in! into the genius of the man. the famous area where he had his photo taken.

you can get a photograph, donna had, the great ship, a famous photo of him taken on the thames —— don a hat. going through here, this is his dining room in london, porches of his family on the wall, and this silverware was presented to him by the company behind the ss great britain —— portraits. i love this interactive map which shows you the root of the great western railway. from london in the east all the way down to bristol, topographically accurate, this is. and as you can see, we even have an image of isambard kingdom brunel‘s and sketching things like the box tunnel, the viaduct, smoking his cigar as he does all of it. that shows you some of his genius, and here is the man himself, the big daddy of british engineering, com plete daddy of british engineering, complete with cigar. looking down and looming large over us. good morning to you. you are the curator. he is keeping an eye on you and

making sure you have it all right. tell us what you have here. so these are his drawing instruments. you can see engraved on the bed, isambard kingdom brunel, and when you open it up kingdom brunel, and when you open it up you can see all these really precise instruments and every single one is engraved with his initials. so when brunel started out he could only afford one drawing instrument ata time only afford one drawing instrument at a time but as he grew more successful he was able to afford these really beautiful sets. and you get a good insight into his life, and we know his achievements, we still travel on them every day. what sort of bloke was he? what was he really like? i think he was terrific fun. one of his friends called him the life and soul of the party which is something i didn't know about brunel. he loved amateur dramatics. there is a great account of him dressing up as an old woman in some amateur dramatics, but he was also racked by self—doubt. he is very far away from the confident engineer we see from the images of him, and i

think that is one of the exciting things for visitors, because we can all relate to someone who appears confident on the outside but internally is worried desperately what people think of them. thank you very much indeed, so much more from you later on and we will have a play with some of the artefact inside the museum. the museum opens today, and some of the original drawings, incredible to see. going right from the sketchpad level of the first germination of an amazing idea right the way through to accurate pictures that the draughtsmen have drawn up, through to completion itself. the atmospheric railway on the south devon coast perhaps not one of his best successes. more from us later in the show. that is a big bust next to you, isn't it? it sure is. and the really big cigar. yes, impressive. time now to get the news, travel and weather where you are.

good morning from bbc london news. i'm tolu adeoye. at least nine people have been fatally stabbed or shot in london within the last week, and today public health officials will gather at city hall to discuss knife crime in the capital. the mayor, sadiq khan, wants to work with 0fsted to educate young people in schools. the home office has also launched a new social media campaign to reduce knife crime amongst young people. the met has apologised after two officers took a selfie at a murder scene and posted it on twitter. officers from newham took the photo outside the stratford centre on thursday, where a man had been fatally stabbed two days before. a spokesman said the officers showed a lack ofjudgement and sensitivity. a group of mps has backed the construction of a third runway at heathrow, but say more needs to be done to minimise noise and pollution. the report by the transport select committee says that the government should include more detail to ensure that passengers and residents living nearby are protected. we are calling for additional

safeguards and information in relation to things like air quality, noise, costs and charges, and surface access, to ensure that the needs of passengers are protected, but also that we address the potential impact on local communities. a new exhibition is highlighting the history of digging under london. it will look at tunnelling beneath the capital from the early 19th century right up to crossrail. it opens at the london transport museum today. let's have a look at the travel situation now. there are severe delays on the district line. a good service on all other lines. on to the trains: there are cancellations on hull trains into kings cross, and that is due to a lack of available trains. the a13 is slow moving from dagenham to barking. the usual delays there. the m25 is slow anticlockwise towards the dartford tunnel after a breakdown earlier lets have a check on the weather now, with elizabeth rizzini.

hello, good morning. once again it is a frost—free start to the day, with temperatures between five and eight celsius, but a pretty disappointing early start. it is cloudy and it is damp, but should shape up to be a fairly decent day of weather, and we'll see some good spells of sunshine around. the breeze will gradually lighten. so a weather front is moving its way eastwards. by the time you to the end of the morning rush hour, it should have gone, and the sky will brighten behind it. we'll see some good spells of sunshine develop. just a small chance of one or two isolated showers through the afternoon, but i think most of us are likely to stay dry. the sunshine turning a bit hazier with the arrival of more high cloud later on through the day. top temperatures 12 or 13 degrees celsius. now, through this evening and overnight, again it's likely to be frost—free. but, as you can see, we're likely to see some outbreaks of rain. it will be quite light and patchy

into tomorrow morning. a lot of cloud, lows of four or five degrees celsius. over the weekend, we're keeping that cloud on saturday. again some outbreaks of light, patchy rain and drizzle. don't forget the clocks spring forward one hour on sunday morning. sunday the nicer day, with lots of sunshine, and highs of 13 degrees. i'm back with the latest from bbc london in half an hour. plenty more on our website at the usual address. details on the screen now. bye for now. hello, this is breakfast, with charlie stayt and naga munchetty. obesity threatens to overtake smoking as the number one preventable cause of cancer. a major study suggests that nearly 40% of all cancer cases could be avoided if people adopted healthier lifestyles. good morning, it's friday the 23rd of march.

also this morning: the eu withdraws its ambassador to russia in support of theresa may as the police officer exposed to a nerve agent in salisbury says his life will never be the same again. on the brink of a trade war. china hits back at president trump with plans for big tariffs on us imports. good morning. trampolining, ten pin bowling — over the past five years we've spent 20% more on good clean fun. i'll be looking at why. good morning. in sport, new zealand extend their first innings lead over england in the first test but it's raining in auckland. england couldn't get a draw after that shocking start, could they? and it's sport relief, i'll be meeting some of the celebrities taking part here in salford and looking at whether dan will be

getting his hands on that trophy as the bbc and itv go head to head on the water. have you got yours? the royal wedding invitations are in the post, harry and meghan reveal the dress code for their big day. good morning. first, our main story. nearly 40% of all cancers diagnosed in the uk every year could be avoided if people adopted a healthier lifestyle, that's more than 135,000 cases. the study conducted by cancer research uk also warns that obesity could overtake smoking as the biggest cause of the disease. here's more from our health correspondent, dominic hughes. exercise is now an important part of kath bebbington's life, but that hasn't always been the case. this was a couple of months after i had my operation. in 2014 she was diagnosed with cancer of the womb. shall never know for sure but kath felt the extra weight she was carrying was a factor so she decided she needed to make changes in her life. i've got six grandchildren so to be around for them,

to be around for my children, they bring such a lot ofjoy and the thought of not being able to grow up alongside them and see them achieving what they want to achieve, itjust made sense to do something. the latest data on cancer shows that smoking is responsible for more than 54,000 cancer cases each year. 22,000 people are diagnosed with 13 types of cancer linked to obesity. skin cancer, caused by too much ultraviolet radiation from the sun or sunbeds, affects more than 13,000 people. we would hope we would continue to see smoking rates coming down, they have been coming down at around 1% per year, so hopefully that trend would continue, if not accelerate. sadly we're not yet seeing the turnaround in obesity related activity yet or obesity related cancer, so clearly the expectation would be if we did this again in seven years time we would see those two getting closer together as risk factors for cancer. a healthy diet and more exercise

have left kath feeling better than ever. today's report is further evidence that following kath‘s example could reduce the risk of cancer for all of us. dominic hughes, bbc news. the european union has taken the rare step of recalling its ambassador to russia, following the nerve agent attack in salisbury. it's being seen as a show of solidarity with britain after eu leaders agreed it was highly likely that moscow was responsible for the poisoning. ben ando reports. in brussels, the prime minister is asking for solidarity, not separation. last night the eu answered by withdrawing its envoy in moscow for consultations, sending, said theresa may, a message to russia. it is a threat to our values, and it is right that here in the eu council, we are standing together to uphold those values. earlier, at a press conference, the message hadn't been quite as decisive. we will discuss the salisbury attack

during our working dinner, and we'll be ready to... to answer more precisely. sergei skripal and his daughter remain critically ill, but police officer nick bailey, hurt after going to help, was well enough to be sent home from hospital. nick has had to undergo significant medical treatment, which has undoubtedly been very daunting for him and for his family. i have personally been amazed at the strength and resilience of nick. in brussels, the prime minister seems to have convinced britain's european allies to stand strong on russia. later today they'll be talking brexit, where she may be hoping for a softer approach. ben ando, bbc news. damian grammaticus is in brussels for us this morning. so, damian, talk us through the logistics, this is one of those days

when theresa may is on the outside looking in, as it were? she will be, yes. first of all, she will be on the inside. the leaders here till after midnight last night discussing the salisbury attack and other things, they're coming back now, just due to start arriving again. now, she will be in the discussions about trade and tariffs. the eu, of course, heard yesterday, or late last night, that it will for now be exempted from the us tariffs on aluminium and steel, that's good news. mrs may will take part in those discussions, then she will leave, as the leaders move on to talking about brexit today's. and the other leaders are expected to do two things, first of all to give their approval to the progress so far, the outlying agreement for a transition period and for the exit deal with the uk. that would be a welcome signal. but they're also likely to signal that the uk, they say, will have to

address the question of the northern ireland border to get more progress. then they will also sign off, we believe, on the negotiating guidelines from the eu side for that future relationship, the trade relationship, that all—importa nt negotiation that will happen to define what the uk's relationship will be after it has formally exited the eu. so that will be approved as well, which will mean the green light for some of those talks to begin. damian, for the moment, thank you. president trump has sacked his national security advisor for the second time in 14 months. general hr mcmaster will be replaced byjohn bolton. he has previously served as america's envoy to the un and has backed carrying out attacks on iran and north korea. meanwhile, china says it's disappointed by president trump's announcement that he plans to impose tariffs worth tens of billions of pounds on chinese imports. the white house said the duties were necessary and a retaliation for years of unfair competition from beijing. our china correspondent stephen mcdonelljoins us live from hong kong. well, the ripples that went through

the financial world when this was announced late yesterday were significant, and the diplomacy that's going to follow from this, or not, should we say, is going to be even more interesting i think. absolutely. we're already getting some very tough talk out of the government here, for example, the spokesperson for the chinese commerce ministry has said china will not sit idly by, that it will do what it has to to defend its own interests, and that while china doesn't want a trade war, nor is it afraid of engaging in one. now, this came after a series of rocks that we re came after a series of rocks that were announced by the chinese government saying, well, we're thinking of putting our own tariffs on american fruit and nuts, pork, steel tubing, wine. —— products. a

kind of first shot across the bow if you like. those provisions were introduced in response to the first round of washington's tariffs, those are the ones on steel and aluminium, that was before this latest round from the us government, so i think we can expect china to pull some more threads out and this is what worries analysts, why we could be careering towards a trade war is situation and we'll know china is getting really serious when it sta rts getting really serious when it starts cancelling orders for boeing jets, or perhaps whacking tariffs on caterpillar's heavy machinery and the like, but certainly it's got plenty of options available to it. it's going to be a fascinating one to watch. stephen mcdonell, thanks very much. charities are welcoming a new campaign aimed at reducing knife crime across the uk. the project features real life accounts from victims and is being targeted at children as young as 10. the home office adverts will be placed across social media platforms. a driver who hit speeds of 139mph while fleeing police has been

jailed for 21 months. rimell taylor led officers on a 12—minute chase on the a47 in wisbech in cambridgeshire. he was convicted for dangerous driving, driving while disqualified, over the limit and without insurance. invitations to prince harry and meghan markle's wedding have been sent out. have you got yours yet? i suppose the obvious answer is not yet. do you want some detail on this? they've been made using american ink, on english card, and printed by a company called barnard and westwood. the couple have invited 600 guests, with a further 200 invited to the reception. lottie small is the printer, who has recently finished her apprenticeship, and was given the opportunity to make the invites. she used a machine, which she nicknamed maude, to print every invitation.

the dress code for guests attending the ceremony is uniform, morning coat or lounge suit, or day dress with a hat. the invitations are similar to the ones sent out for the william and kate's wedding in 2011, although these were in a different font and were issued with the queen's royal cypher. you have all the information you need. what more could you want to know? we will have the sport and the weather coming up a little bit later. the european union has taken the rare step of recalling its ambassador to russia, following the nerve agent attack in salisbury. it's being seen as a show of solidarity with britain after eu leaders agreed it was highly likely that moscow was responsible for the poisoning. the move is highly unusual and is being seen as a sign of solidarity. eleanor bindman is a

russian politics analyst what do you make of this move? theresa may yesterday was trying very ha rd yesterday theresa may yesterday was trying very hard yesterday to get people on her side and there have been some cautious comments from various leaders. it's been an escalation in terms of the seriousness of the state m e nts terms of the seriousness of the statements coming from the eu council at this stage. i think the fa ct council at this stage. i think the fact they're recording the ambassador, it could be for consultation at the moment, it's important not to overstate it in terms of how serious it is —— recalling. you can consult an ambassador without recalling them ? you can consult an ambassador without recalling them? it is designed to send a symbol and it is symbolic, that shows the seriousness with which they are taking it is increasing over time. the reality of course is that is one signal, of one sort, we have sent our own signal by the expulsion of the diplomats, the tit for tat, but the reality is, of course, as we know from putin's re—

election, and the messages from all over the world congratulating him on his win, that to a degree nothing has changed ? not really, but i think it's important to recognise that in terms of things like juncker for example congratulating putting on his win and other world leaders following suit, that's quite a normal part of diplomacy —— peruvian. it's not the same as saying they approve of what he's doing, they very much doubt, but that's sort of expected in terms of international relations so i think that's quite a normal process. it is normal and everyone understands he is the leader of russia and business still has to go on of some description, but that presents a problem when you're trying to send a message? theresa may would like the message to be stronger, we didn't send a congratulations message to president putin, she would have loved someone else to do the same thing?” putin, she would have loved someone else to do the same thing? i think that's probably true but particularly when you look at how the eu works and how its

relationship with russia has to work, they have to take a quite pragmatic approach, of course they consider what happens in the uk and they're taking that quite seriously but the uk is one member amongst many and a lot of eu member states have quite different relationships with russia and views on how that should go forward. that's based on economic ties or historical ties? without going into detail of each 27 member, how roughly is it aligning? for example, countries like poland tend to take a pretty hard line on russia generally, that's partly for historical reasons, but also for political reasons as well. the baltic states, estonia, latvia, lithuania also generally take quite a hard line. what about our friends, so to speak, closest friends, france, germany? again there in quite a difficult position, they prefer to take generally a pragmatic approach and germany in particular has been quite keen to... russia has been very

isolated over the last three or four yea rs isolated over the last three or four years in the wake of the ukraine crisis and they were keen to start some kind of dialogue, that may be on hold for now but they have a tricky balancing act. is that because of any economic ties? there are strong ties between german companies and russian companies, lots of shared interests, but actually politically again they tend to not want to isolate them too much and be very pragmatic about their approach. looking forward, eleanor, do you think this is effectively the low point of our relations with russia, and if it were to get worse, how would that manifested itself? what would that look like?” how would that manifested itself? what would that look like? i think it's a very low point. i think it definitely increases russia's international isolation more generally but from a uk perspective it's hard to see how it could get much worse at this stage and what else the british government could do. we also need to wait for the results of the investigation into the actual poisoning that's ongoing. do you think the fact that we're

leaving the eu is having a bearing on the way of support we have? we are still a member of the eu, still are still a member of the eu, still a member of the european union, yet... what i think there's probably an element of that, although i think over the past week because of the seriousness of which they're taking it has seemed to wrap up a bit. i think there's one thing to have serious words about serious statements, but that doesn't necessarily mean that will translate into action and i think certainly britain has fewer friends into action and i think certainly britain has fewerfriends in europe thanit britain has fewerfriends in europe than it once did. thank you, eleanor bindman, a lecturer in and eu politics. thank you. it is the big sport relief extravaganza today, and for the first time, the show will be coming live from media city in salford. they will be going for i think it is 12 hours, a marathon session going

on. you can't quite see in the shot, there is an assault course, zip wires, zorbing... there is an assault course, zip wires, zorbing. .. i there is an assault course, zip wires, zorbing... i don't know another z word. at the weather is fine. do you have another word again in with z which is a meteorological term? to be honest, i am distracted at the thought of charlie zip wiring later in the programme.” at the thought of charlie zip wiring later in the programme. i don't remember that conversation, i don't remember that conversation, i don't remember hearing that.” remember that conversation, i don't remember hearing that. i have seen the running order, anyway, weatherwise it is dry out there later on. things improving across many parts of the uk after what for some of you is a bit of a wet start. let me show you the satellite imagery, the cloud pushing enough the atlantic. this little hookers delaying the appearance of rain from scotla nd delaying the appearance of rain from scotland and northern ireland, but this stripe of cloud will cause a

bit of weather over the next few hours. it will clear away from east anglia and the south—east, then the skies will clear, and for the rest of the rush—hour one or two showers across wales in the far north of england. that leads to heavy showers across northern ireland working our way in the southern scotland. after a brief respite from the rain, there is more to come. it will clear away from the highlands after a wet couple of hours, and the rain will stay there or thereabouts through much of the morning into the early afternoon. wet in shetland but here we might see something brighter before the end of the day. isolated showers into the afternoon, much of england and wales dry with sunny spells, the sunshine turning hazy from the south—west later on. a fine afternoon compared with the morning for most of you. nine or 10 celsius across scotland and northern ireland. a few showers to wind the day in northern ireland and southern scotland, they will fade through the night. clearer skies here. a lot more cloud across england and wales linking into this weather system pushing off into france, but throwing off a little bit of rain.

damp weather through southern parts of england and wales so tonight should be too chilly across southern areas. a frost here into the start of the weekend. for some of you, a chilly start to the weekend. by and large a fairly average weekend, temperatures where they should be for the time of year, and while we will see some damp weather, many will see some damp weather, many will be dry. even the rain will be light and patchy, skies slowly brightening for many but remaining a bit grey into the afternoon in east anglia and the south—east. a few showers in the south—east, some of those showers could be heavy. a decent amount of sunshine in between and some in the northern half of the uk staying dry throughout saturday. a better chance of staying dry through sunday, a brighter day the southern parts compared with saturday. long sunny spells here. a few showers in north wales, northern england northwards. feeling a bit cooler in the north—west breeze, but a slightly warmer day further south. temperatures tend to 13 degrees, not

looking too bad. doing better at the moment than other parts of europe. let me show you the scene in central and southern italy yesterday. some very heavy snowfall on the blossoming trees out there. the reason i am showing you that is to make it not seem so bad when i say next week it is set to turn colder and there will be some snow back here. when you show us pictures like that, you are basically hinting that we have another beast coming. not necessarily, we will see a little bit of snow but i can't say how much we will see at the moment. but things turn a little bit colder next week, certainly after this weekend. are we getting their weather? slightly different weather but other parts of europe certainly having plenty of snowfall. i think italy has had the brunt of it over the last 24 hours. we all know how important dna is to understanding human health but now scientists think it could be used to solve another global

problem: data storage. it may sound odd but all those videos and photographs we love to take could one day be stored in the form of dna, saving huge amounts of space and energy. our science correspondent richard westcott explains. we are producing data at a staggering rate. all those videos, social media posts, online forums, and "look where i am" selfies. the problem is it takes a huge amount of computer space and energy to store it all. so could the answer lie somewhere else, somewhere deep inside us all? i could not resist making a video of this beautiful replica of the famous watson and crick double—helix, the model of dna that changed the world. but what if i could store the video i am making now onto a piece of dna. we take the movie file you sent me,

which on a computer is zeros and ones, and we convert that into a, c, g, and ts. cambridge mathematician nick goldman has devised a way to turn computer code into dna code. it means you can use the dna as a kind of hard drive. tell us about the day when you came up with the idea. the day was a big meeting discussing how we were going to keep on storing large amount of information coming from experiments on dna. we went to the bar and started talking about other ways we might store the information. and in a lightbulb moment, we realised that the dna we'd been worrying about was itself a way of storing information. an american company turns nick's code into physical dna. it is a secret process, but they told us why it is so effective. so the first huge benefit of dna is that it's extremely dense. and if we stored all the data that is on the internet in dna,

that would be the size of a shoebox. and then the second main benefit of dna is that it's permanent. you could store it forever, which is very different from, a normal medium, which ages very rapidly. back at the institute in cambridge, they are world leaders in reading dna. these machines are scanning the code of everything from human beings to diseases like dysentery. and something hasjust arrived for us in the post. so this is what comes back from america. this is your report stored on dna. where is it? it's just there. the big question, then — did it work? could you read my video back. we put the file back together again and it's this file here. there it is. it does not look like there any errors in it at all. no, and we checked, and it's a perfect copy

of the file. every single zero, every single one is correctly reproduced. big companies including microsoft are also looking at dna storage. it is still too expensive and too slow, but that could soon change. in five years it will be advanced enough that, if you've got a lot of money and very valuable information, you might think about going this way. and maybe 10—15 years before there's a product that you and i would buy for our personal use. richard westcott, bbc news, talking to you from a piece of dna. there is a lot to conjure with from that report. and when i was seeing that report. and when i was seeing that i was thinking does that mean the human body will be the vessel in which the data will be stored? but thatis which the data will be stored? but that is not the point, because it is not human dna, but are created form of dna. do you know how they have to store the dna? it has to be really

cold, —18 degrees as well. so where would that be stored? how much can the powder form be would that be stored? how much can the powderform be changed? we have lots of questions. if you have lots of questions, because this is a sign of questions, because this is a sign of the future, with big companies like microsoft involved in the development of this, this could become a reality in ten to 15 years. please get in touch with us the usual way, on twitter, please get in touch with us the usualway, on twitter, e—mailand our facebook page. so that is about extraordinary things happening in the future. we are also sort of celebrating amazing achievements of the past in the realms of engineering. john can explain a bit more from bristol. good morning. you are right to say we are celebrating the past, but also very much the present and the future. we are at a brand—new museum in bristol called being brunel, and they are the men is himself. —— there is the man himself. to give you an idea of

exactly where we are, we are right next to the ss great britain in bristol, just why the floating harbour. pretty much everything you can see was designed or imagined by brunel, one way or another. the reason i say it is not about history, it is about the present, because if you catch the train from the west country to london, even if you have been on a trans— atlantic or oceanic voyage, a you have been on a trans— atlantic or oceanic voyage, a lot of that stuff was pioneered by brunel himself, an extraordinary exhibit space. they have also recreated some of his rooms from the 19th century. you are the curator and you have some wonderful things to show us throughout the morning. what are we looking at? he would have used these drawing curves when laying out the root of the great western railway, designing his bridges. as you can see, they are really, really fine, so see, they are really, really fine, so really precise instruments. they all have a little measurement on them. that is five inches and an eighth, and that is another one, and

here you can see the stamp. let's show that to the folks at home. so these were his offices in london. and he moved here and built the suspension bridge and the ss great britain and so many amazing things. and why is he still important today? well, he built prison. but as you mention, so many inventions now would not have happened without him. so ss great britain is the great grandmother of all ocean liners, we still use the great western railway, and without all of his innovation i don't think it would have in the great industrial power that she was. thank you so much. an incredible diet, he died at the age of 53, i think i remember, so achieved an incredible amount in just a short life. i will tell you incredible amount in just a short life. iwill tell you more incredible amount in just a short life. i will tell you more about him after the news, travel and weather where you are watching breakfast this morning. good morning from bbc london news,

i'm tolu adeoye. at least nine people have been fatally stabbed or shot in london within the last week, and today public health officials will gather at city hall to discuss knife crime in the capital. the mayor, sadiq khan, wants to work with 0fsted to educate young people in schools. while the home office has launched a new social media campaign to help reduce knife crime amongst young people. the met has apologised after two officers took a selfie at a murder scene and posted it on twitter. officers from newham took the photo outside the stratford centre on thursday, where a man had been fatally stabbed two days before. a spokesman said the officers showed a lack ofjudgement and sensitivity. a group of mps has backed the construction of a third runway at heathrow, but say more needs to be done to minimise noise and pollution. the report by the transport select committee says that the government should include more detail to ensure that passengers and residents living nearby are protected. we're calling for additional

safeguards and information in relation to things like air quality, noise, costs and charges, and surface access, to ensure that the needs of passengers are protected, but also that we address the potential impact on local communities. a new exhibition is highlighting the history of digging under london. it will look at tunnelling beneath the capital from the early 19th century right up to crossrail. it opens at the london transport museum today. let's have a look at the travel situation now. there are minor delays on the district line due to a signal failure, a good service though on all other lines. on the trains, there are cancellations on hull trains into kings cross, that's due to a lack of available trains. we can see on the camera there, the highway is slow westbound into town between limehouse and tower bridge. the m25 is slow anticlockwise towards the dartford tunnel after a breakdown earlier. let's have a check on the weather now with elizabeth rizzini. hello, good morning. once again it's a frost—free

start to the day. we've got temperatures between five and eight degrees celsius, but a pretty disappointing early start. it's cloudy and it's damp, but should shape up to be a fairly decent day of weather, and we'll see some good spells of sunshine around. the breeze will gradually lighten. so a weather front is moving its way eastwards. by the time we to the end of the morning rush hour, it should have gone, and the sky will brighten behind it. we'll see some good spells of sunshine develop. just the small chance of one or two isolated showers through the afternoon, but i think most of us are likely to stay dry. the sunshine turning a bit hazier with the arrival of more high cloud a bit later on through the day. top temperatures of 12 or 13 degrees celsius. now, through this evening and overnight, again it's likely to be frost—free. but, as you can see, we're likely to see some outbreaks of rain. it will be quite light and patchy into tomorrow morning. a lot of cloud, lows of four or five degrees celsius. over the weekend, we're keeping that cloud on saturday. again some outbreaks of light, patchy rain and drizzle.

don't forget the clocks spring forward one hour on sunday morning. sunday the nicer day, with lots of sunshine, and highs of 13 degrees. i'm back with the latest from bbc london in half an hour. plenty more on our website at the usual address. now it's back to charlie and naga. bye for now. hello, this is breakfast with charlie stayt and naga munchetty. here's a summary of this morning's main stories from bbc news: nearly 40% of all cancers diagnosed in the uk could be avoided if people adopted a healthier lifestyle, according to a new study. cancer research uk says 135,000 cases every year are preventable. the charity is also warning that obesity could eventually overtake smoking as the biggest cause of the disease. the european union has taken the rare step of recalling its ambassador to russia following the nerve agent attack in salisbury. the show of solidarity with britain comes after eu leaders, meeting at a summit in brussels, agreed it was highly likely that moscow was responsible for the poisoning. theresa may has delayed her departure from the summit to attend talks on trade and us tariffs.

president trump has sacked his national security advisor for the second time in 14 months. general hr mcmaster will be replaced byjohn bolton. he has previously served as america's envoy to the un and has backed carrying out attacks on iran and north korea. is all being sore the high street retailer, next, has published its results, and they're not great. nina's here with more. we always keep a close eye on next, we call them a bellwether store, what they're doing is a wider picture of what we're doing on the high street. and 8.1% fall in annual pre—tax profits, not disastrous, they still made more than £700 million but a good christmas surprisingly so they'll be disappointed. the chief executive lord woolson said we hold our hands up, we made bad decisions with the

wrong stock on the shelves and we missed some trends. it feeds into a wider picture, we talked yesterday about copyright and moss bros and b&q, all having a bad time at the moment. good news for next, online sales up 10%, we keep saying the retailers focusing on online and doing well seem to be weathering the high street storm really well. always the next sale, that's how you judged how the high street was doing, people looked forward to that. they did well at christmas, better—than—expected, so people will better—than—expected, so people will be disappointed today there. charities are welcoming a new campaign aimed at reducing knife crime across the uk. the project features real life accounts from victims and is being targeted at children as young as 10. the home office adverts will be placed across social media platforms. 150 whales have become stranded on a beach in western australia. fishermen spotted the short—finned pilot whales at hamelin bay near perth early this morning. conservationists say at least of half of them have died. bad weather conditions are hampering efforts to rescue the surviving

animals and move them back out to sea. the authorities have also issued a shark alert, warning people to stay away from the area. invitations to prince harry and meghan markle's wedding have been sent out. just a few months away now! they've been made by barnard and westwood using american ink on english card. you see what they did there? you can see lottie small there, who had recently finished her apprenticeship with the printers, and was given the opportunity to make the invites. she used the machine, which she nicknamed maude, to print every invitation. the couple have invited 600 guests, with a further 200 invited to the reception. how many sets of eyes do the checks on that invitation? a lot of people

i would say. i think that would have been a process of weeks, agreeing the wording. it is coming now from his royal highness inviting the couple, which is slightly different to william and kate's imitation, shows they're doing something a bit different. 600 guests to the wedding, 200 to the disco afterwards. a disco? a disco? that's not what it says on the invitation. you have just told not what it says on the invitation. you havejust told us not what it says on the invitation. you have just told us that harry and meghan will be discovering. that's my interpretation! carol will be here with the weather shortly. we should have a look at salford quays this morning because that's where sport relief is coming today and this weekend. john, you will only earlier but, oh, careful! i'm in the worst possible spot. thing is heating up for sport relief.

kicks off on bbc one at 7am but a series of events happening at media city today. this is the 5 live side footy pitch where robbie savage and celebrities will be taking place in back—to—back five aside matches, from 11am, 12 hours solid, what a test of endurance! and shay given, who is the former republic of ireland goalkeeper, he's taking part ina ireland goalkeeper, he's taking part in a non—stop penalty shootout again for 12 hours, members of the public will come down and have the chance to ta ke will come down and have the chance to take a penalty against him all in aid of sport relief, which, since 2002 when it launched, has raised £330 million for the vulnerable across the uk and abroad. we will be speaking to robbie and sam kwek, who is on his team, in a moment. only one place to start with this morning, though! to england's cricketers, and what chance of them restoring some pride, at least, after that dreadful start to the first test

against new zealand. well, not much at the moment, the home side had extended their lead to 171 when play was interrupted by rain, three wickets forjimmy anderson, new zealand now 229—4. the home side extended their lead before rain interrupted play, a lead of 171, three wickets forjames anderson and stuart broad with the other. a pitch inspectionjune shortly so we will see if we get more play on day two. gareth bale is now wales' record goal—scorer thanks to a hat—trick in a friendly against china. it was a spectacular debut for new manager ryan giggs, with wales dominating the match in nanning, 6—0 it finished, and bale has 29 goals to his name, breaking ian rush's record. it's amazing. i think on my daughter's birthday today, so obviously happy birthday to her, obviously disappointed i can't be with her but it's great individually to get the record, but, as i say, the most important thing is always the team played as well and under a new manager it's important to get off to a good start.

england manager gareth southgate says he has no concerns about security and safety at this summer's world cup in russia. but even though he believes the atmosphere will be good in the stadiums, he suspects the england team won't be anyone's favourites. i don't think we're going to be the most popular the way things are going at the moment, but maybe that's something we've been used to over my career with different teams. maybe that can be some extra motivation for us. they play the netherlands in a friendly later. and formula one is back with us, lewis hamilton was quickest in second practice for the australian grand prix, although there wasn't much between the top three teams, with red bull and ferrari very close behind. and with rain expected during qualifying the the race itself, we could be in for an exciting weekend in melbourne. as we are here today at media city, with sport relief upon us. robbie and sam are with us. robbie, this isn't your first involvement in sport relief. you played that

mammoth 57 hours of football two yea rs mammoth 57 hours of football two years ago and you're back with your five aside team this year, excited? really excited, we've got a fantastic team of celebrities to do the challenge. as you say, it's my third challenge, i'm going to miss alan shearer last year —— this year, we've raised nearly £2 million so hopefully we can increase that this year. sam, your olympic gold winning success coming to this team? yeah, but that is in hockey! but defensive qualities? my defensive, competitive side, i played football when i was younger so side, i played football when i was younger so hopefully i can get the team through this long 12 hours —— my competitive side. ever played sport for that long? no, it will be a good challenge, but a good laugh on the way so it shouldn't be a difficult thing. teams from the fa people's cup coming down?‘ difficult thing. teams from the fa people's cup coming down? a lot of sides will come and play but i have

to stay on for 12 hours, which will be very tough, but all for a good cause. who else have you got on your team? kirsty gallacher and michael vaughan. harry judd, peter team? kirsty gallacher and michael vaughan. harryjudd, peter reid is our manager, looking forward to seeing peter, inspirational manager, can't wait. fantastic, it will be amazing, and as you say, all for a very worthy call is, sport relief. we have children from listerjunior school, perhaps we should join them with a little kick about this morning? —— very worthy cause. with a little kick about this morning? -- very worthy cause. you area morning? -- very worthy cause. you are a brave person, mr watson, kicking around with robbie savage. we are going to do a bit of commentary. no, it has all gone wrong already, a young man on the floor, is he ok? back up again! let's put it all into context for you, john, thank you! they are on

the piazza outside this studio. also outside the studio is the water. and what's been happening on the water? the clash of the channels boat race. itv against bbc, let's have a look. that's enough! its official title, the clash of the channels boat race, bbc versus itv. but we all know what this is all about, bbc breakfast versus this is all about, bbc breakfast versus good morning ridden. weezer says if i don't win i can't come back on monday. piers morgan has made it clear i don't have a job if i lose this. dan walker versus charlotte hawkins. we know we're doing it for a great cause, we're doing it for a great cause, we're doing it for sport relief and we love that but everyone here is super competitive. how do you compare against dan walker in a boat? i'm a

bit worried about that, year he's done it before so he's got a bit of advantage, but he's got long legs and long arms so he could be uncoordinated. the thought of piers morgan watching this?” uncoordinated. the thought of piers morgan watching this? i can't even mention his name but if he was really prepared and he had the physical and mental capabilities he would be here himself in the boat, charlotte is here instead, but like every single morning, he will end up second. piers will make my life hell for ever more, itjust second. piers will make my life hell for ever more, it just won't second. piers will make my life hell for ever more, itjust won't be worth living. and it's pretty clear what the rest of dan's celebrity crew make of him. he's at the front of the boat so he sets the pace, basically when he rose, everyone else has to match his pace so it's a position of incredible responsibility. if we mess up essentially it's his fault. i can't be blamed, i'm just doing what he does. well, he keeps trying to do high fives in a sportsman olympian lightweight, yeah, we've got this. he'sa man lightweight, yeah, we've got this. he's a man who can bring us victory or lead us to defeat. and as for the

race, to find out who one, you'll have to watch tonight's sport relief on bbc one. but we did catch up with dan and charlotte for an after race spoilerfree dan and charlotte for an after race spoiler free interview. bovine tb and bbc crews having a laugh, giggling at each other, as soon as that was on the start line, no one said a word —— both itv. cereus nerves, not kidding. a proper competition. it really was. how are your shoulders? i didn't even want to look at the other boat, sirius bases, don't know if i am going to walk tomorrow, let alone move my shoulders. we will find out tomorrow on bbc food sir steve redgrave will be handing this trophy to. colin paterson, bbc news, totally impartial, come on bbc breakfast! to write, you will find out who was big story slater on the night! calculators, a priceless tool

against the tyranny of timetables for many children but formats purists they are a soft option that ta ke purists they are a soft option that take away from a proper understanding of numbers —— for maths purists. but it has been revealed that it can help. colin foster joins revealed that it can help. colin fosterjoins us revealed that it can help. colin foster joins us now. revealed that it can help. colin fosterjoins us now. good morning. there really has been this tradition, when i was at school we didn't use calculators and less we we re didn't use calculators and less we were doing things like cosine and tan, that's only when you were allowed to use it, otherwise you worked out your multiplications and divisions in your head. why has that changed? the world has changed and now if people are multiplying two or three digit numbers no one would do that without a calculator and we need to help students live in that world and be able to use calculators intelligently, that means having a sense of the size of the answer they

would expect so they know when something has been mislead or the technology isn't doing what it should. i will compare that to spellcheck, people use spellcheck so aren't learning to spell, you could use the argument in the same way, you can do three numbers together on paper and use your brain and it's a logical process. there's nothing wrong with that and we're not saying children must always use calculators and never do written and mental calculation is but we're saying the research we looked that, we looked at the best available international research, and it shows using calculators supports the mental and written calculation methods children use. if calculator is used sensibly it can help the students understand what they are doing that if calculators are used. do you have to change the nature of the questions? -- is change the nature of the questions? —— is calculator is used. if you're asking me a question and i have a calculator —— if calculators are used. what is 200 divided by 4.5 andi

are used. what is 200 divided by 4.5 and i put it in the calculator i give you the answer, that's not maths, that is me pushing buttons. what's the point in asking a question like that if someone has a calculator? there wouldn't be, it means you can ask more interesting and harder questions. before calculator as the numbers in questions had to be chosen really carefully so the answers would come out nicely. in pencil and paper techniques. but with calculators you can use realistic numbers. sometimes in the past, students could guess what operation, whether it was multiplication or division, by the numbers which were chosen for the question. can i ask other things. we often told that education generally should be related to the real world. in the real world, when you are talking to a shopkeeper they have overcharged you and want to do the calculation, you won't get your calculator out, will you? calculation, you won't get your calculator out, will you ? you calculation, you won't get your calculator out, will you? you still need to be able to do stuff in your head as a ballpark idea, and if you entirely are reliant on the

machinery, then aren't you left a bit up the creek when you possibly need it most? shore, and that is how we think calculate as can be best used in the classroom, to support that mental work. —— sure. so when kids are trying to work out an estimate of the calculation faster than someone can key in the numbers and get the answer on a calculate, tasks like that can support kids in their sense of how big numbers should be, so they know when the technology is working correctly and when it isn't. and doing the maths gsce questions, with my kids, is really tough. it is tough living in study, that is what is tough. we sit three papers, and one of them is without a calculator. so it has not been abandoned, and two with a calculator, and i think this was the point, that you have to show you have worked out, you have all the

methodology, but use the calculator for the detailed numbers. you can use more realistic numbers for the problems. so it is not that all tests will involve a calculator, some of the year 6 tests are non— calculator, not what we are saying is they are useful opportunities for experiences in the castle classroom where kids can use calculator is, evenif where kids can use calculator is, even if they are preparing for the non— calculator test. when they are given a choice about using kalka letters, the ones who have been taught to use calculator is use it less, and they had learnt to self regulate and not overuse them when they didn't need them. that would be they didn't need them. that would be the kind of goal that we would lean towards. what about the ones who didn't use it? they used calculators more because they were unused to using calculator is, they kind of usedit using calculator is, they kind of used it for everything. thank you very much for your time this morning. bbc breakfast is running

a special series about maths, and you can test your own skills. we have special puzzles on the bbc website. just head to bbc.co.uk/mindset and click on breakfast logo. next week, we will be looking at how maths is taught in schools, and we will have some revision tips for people revising over the easter holidays. plus, there will be some new puzzles. and the south—westerlies are travelling at 235 mph and a volcanic vortex in the north, what is the resulting temperature? vortex in the north, what is the resulting temperature ?” vortex in the north, what is the resulting temperature? i have a whether some for you. a mild weekend plus approaching easter leave wind means it will turn colder, as i shall show you. out there today it is getting better kind of day. the sums are adding up to many parts of the uk. after a wet start for some, more in the way of dry weather later and some sunshine breaking through as well. showing you the satellite imagery, where the coming of the

atla ntic imagery, where the coming of the atlantic at the moment so this is the cloud moving its way from west to east. it is delaying the clea ra nce to east. it is delaying the clearance of rain for some in scotla nd clearance of rain for some in scotland and northern ireland but the cloud across england and wales shifting away. patchy rain in east anglia and the south—east will clear in the next hour or so and then sunny spells breakthrough. a few showers come in but the southern half of the uk for the rest of the rush—hour looking largely dry. more persistent rain becoming confined to the far north, but we do have heavy showers in northern ireland. they will push towards southern scotland and the far north of england in the next couple of hours. we are not com pletely next couple of hours. we are not completely done with the wet weather, and there will be a few more showers throughout the day in parts of scotland, northern ireland and the far north of england. persistent rain is slow to ease away from shetland in the highlands. much of england and wales will be dry through the afternoon. sunshine turning haiti from the west as this weather system approaches, that will dive off towards france but before it arrives, dragging up some reasonably mild air, double—figure temperatures just about across parts of scotla nd temperatures just about across parts of scotland and northern ireland. it

turns cold through the night under clear skies, a fairly windy day by and large. a few showers continuing into southern parts of scotland and the far north of england but cloudy weather into the far south with patchy rain and drizzle keeping temperatures up overnight. in scotla nd temperatures up overnight. in scotland and northern ireland, a frosty start to the weekend with a little bit of ice around as well. overall, the weekend is looking fairly standard for the time of year. temperatures where they should be and a lot of dry weather to enjoy if you have any outdoor plans. there will be some wet weather on saturday across the southern counties of england and wales. patchy, light rain and drizzle slowly easing, becoming confined to the south—east later as well as the channel islands. a few showers breaking out for scotland and northern ireland, some of those heavy with hail and thunder but a lot of dry weather in between those on where the sun is out not feeling too bad. i is around 11 in aberdeen and london. in the sunday, a chilly start of a better

day for england and wales. a lot more sunshine around, most places will be dry and only a few isolated showers in the north and west. across northern ireland in north and west scotland, further showers, maybe a little bit of sleet over higher ground. if anything, maybe a little bit of sleet over higher ground. ifanything, on sunday, especially the england and wales, the milder day for the weekend, with highs around 13. isambard kingdom brunel has been described as the man who built britain, and helped shape the world. a new museum in honour of the esteemed engineer opens today in bristol, and john maguire is there. almost right on top of the water, thatis almost right on top of the water, that is the ss great britain, just to the right of those light buildings. some of the original officers where the ss great britain was designed. so it is bringing the story right round full circle. we are going to take you into a re— creation of his dining room in london, including some of the silverware, the original silverware presented to him by the board of the

ss great britain as a thank you for his work. what they have done is absolutely fascinating, they have used great furniture making techniques. this opens up to show you a map of victorian london. these are some of the souvenirs that were commemorated when the thames tunnel was opened. initially it was brunel‘s father mark who started the project. he then brought his son on board. you go through into the exhibition space, absolutely dominated by an eight metre tall representation of brunel. all sorts of things, he crossed spans, he crossed the country. this is a computer plan which shows you how he mapped it out, it was known as brunel‘s elliott table because it was so flat. it goes in between the contours of the land, and these are the future brunels. good morning to all of you. schoolchildren from bristol, interested in stem, science, technology, engineering and

maths, walking in the boot steps of mr brunel. what got you interested in him? are mac well, i have always been interested in stem, and when i heard about future brunel, it was an opportunity to have more involvement with stem, so i applied for it. would fund so far? are mac yes, it has been fantastic. and visit the maths, the engineering, what gets you excited? i like all of them. they are also amazing. stem is all around us, it is very important to understand how it works and the rules of everything, so i think it is very important. and this is the first time you guys have had a look around here. this is the man who has inspired maybe you and inspired certainly the scheme you are a part of. what do you think about this and what you think about him? of. what do you think about this and what you think about him7m of. what do you think about this and what you think about him? it is amazing. it is such a new insight into his life. people see the ship that this is a new element into his life, and he has done so much for

this world, to be honest, especially bristol, with the bridge and edible meat. and just show the folks at home this board here —— temple meet. and what is great is you see mr brunel‘s cigar appearing there, paddington station in the east, maidenhead bridge, the train works, coming through the box tunnel showing you... i suppose this is his vision, it is absolutely extraordinary to imagine that one man could have created all of this, and he died young age, as well. the great great painting which portrays that, paddle steamers, and we are sitting right next to the ss great britain, and the trick about the great britain was that brunel invented this amazing propulsion system so that for the first time steamships could cross oceans. the ship outside where we are standing now took the first english ashes tea m now took the first english ashes team to australia, for example. the innovation not only back then was

extraordinary to think of, but we live with it to this day and age. and here he is looming large, looking down on us. and when you wander the museum you sort of feel his spirit, you feel he is there with you. you catch the trains, crossed the bridges, cross oceans, and it is all because of the legacy of brunel. it looks marvellous. you are watching breakfast. still to come this morning: she's singing tonight for sport relief. rae morris will be here to tell us about the message of hope in her new single. lots more coverage of sport relief coming up throughout the programme. time now to get the news, travel and weather where you are. good morning from bbc london news, i'm tolu adeoye. (pres) at least nine people have been fatally stabbed or shot in london within the last week and today public health officials will gather at city hall to discuss knife crime in the capital. the mayor sadiq khan wants

to work with ofsted to educate young people in schools. while the home office has launched a new social media campaign to help reduce knife crime amongst young people. the met has apologised after two officers took a selfie at a murder scene and posted it on twitter. officers from newham took the photo outside the stratford centre yesterday, where a man had been fatally stabbed two days before. a spokesman said the officers showed a lack ofjudgement and sensitivity. a group of mps has backed the construction of a third runway at heathrow but say more needs to be done to minimise noise and pollution. the report by the transport select committee says that the government should include more detail to ensure that passengers and residents living nearby are protected. we're calling for additional safeguards and information in relation to things like air quality, noise, costs and charges, and surface access, to ensure that the needs of passengers are protected, but also that we address the potential impact on local communities. a new exhibition is highlighting

the history of digging under london. it will look at tunnelling beneath the capital from the early 19th century right up to crossrail. it opens at the london transport museum today. let's have a look at the travel situation now. there is a good service on all tube lines. on the trains, there are cancellations on hull trains into kings cross, and that's due to a lack of available trains. we can see on the camera there, the highway is slow westbound into town between limehouse and tower bridge. finally, the m25 is slow anticlockwise towards the dartford tunnel after a breakdown earlier. let's have a check on the weather now with elizabeth rizzini. hello, good morning. once again it's a frost—free start to the day. we've got temperatures between five and eight degrees celsius, but a pretty disappointing early start. it's cloudy and it's damp, but should shape up to be a fairly decent day of weather, and we'll see some good spells of sunshine around.

the breeze will gradually lighten. so a weather front is moving its way eastwards. by the time we to the end of the morning rush hour, it should have gone, and the sky will brighten behind it. we'll see some good spells of sunshine develop. just the small chance of one or two isolated showers through the afternoon, but i think most of us are likely to stay dry. the sunshine turning a bit hazier with the arrival of more high cloud a bit later on through the day. top temperatures of 12 or 13 degrees celsius. now, through this evening and overnight, again it's likely to be frost—free. but, as you can see, we're likely to see some outbreaks of rain. it will be quite light and patchy into tomorrow morning. a lot of cloud, lows of four or five degrees celsius. over the weekend, we're keeping that cloud on saturday. again some outbreaks of light, patchy rain and drizzle. don't forget the clocks spring forward one hour on sunday morning. sunday the nicer day, with lots of sunshine, and highs of 13 degrees. i'm back with the latest from bbc london in half an hour. plenty more on our website at the usual address. details are on the screen for you there. va nessa

vanessa feltz also has our breakfast show on radio london. hello, this is breakfast, with charlie stayt and naga munchetty. obesity threatens to overtake smoking as the number one preventable cause of cancer. a major study suggests that nearly 40% of all cancer cases could be avoided if people adopted healthier lifestyles. good morning, it's friday 23rd march.

also this morning... the eu withdraws its ambassador to russia in support of theresa may, as the police officer exposed to a nerve agent in salisbury says his life will never be the same again. on the brink of a trade war — china hits back at president trump with plans for big tariffs on us imports. trampolining, tenpin bowling — over the last five years we've spent 20% more on good clean fun. i'll be looking at why. in sport, new zealand extend their first innings lead over england in the first test, but it's raining in auckland — england couldn't get a draw after that shocking start, could they? and it's sport relief — i'll be meeting some of the celebrities taking part here in salford, and looking at whether dan will be getting his hands on that trophy as the bbc and itv go head to head on the water. and have you got yours? the royal wedding invitations are in the post — harry and meghan reveal the dress code

for their big day. and matt has the weather. and maybe a little big grey out there. but it is a getting better day with sunny spells breaking through. full details and we can forecast 15 minutes. —— and the weekend forecast. good morning. first, our main story. nearly 40% of all cancers diagnosed in the uk every year could be avoided, if people adopted a healthier lifestyle — that's more than 135,000 cases. the study conducted by cancer research uk also warns that obesity could overtake smoking as the biggest cause of the disease. here's more from our health correspondent, dominic hughes. exercise is now an important part of kath bebbington's life, but that hasn't always been the case. this was a couple of months after i'd had my operation. in 2014 she was diagnosed with cancer of the womb. shall never know for sure but kath felt the extra weight she was carrying was a factor, so decided she needed to make changes in her life. i've got six grandchildren so to be around for them, to be around my children,

they bring such a lot ofjoy and the thoughts of not being able to grow up alongside them and see them achieving what they want to achieve, itjust made sense to do something. the latest data on cancer shows that smoking is responsible for more than 54,000 cancer cases each year. 22,000 people are diagnosed with 13 types of cancer linked to obesity. skin cancer, caused by too much ultraviolet radiation from the sun or sunbeds, affects more than 13,000 people. we would hope we would continue to see smoking rates coming down, they have been coming down at around 1% per year, so hopefully that trend would continue, if not accelerate. sadly we're not yet seeing the turnaround in obesity related activity yet or obesity related cancer, so clearly the expectation would be if we did this again in seven years' time we would see those two getting closer together as risk factors for cancer. a healthy diet and more exercise

have left kath feeling better than ever. today's report is further evidence that following kath's example could reduce the risk of cancer for all of us. dominic hughes, bbc news. the european union has taken the rare step of recalling its ambassador to russia, following the nerve agent attack in salisbury. it's being seen as a show of solidarity with britain, after eu leaders agreed it was "highly likely" that moscow was responsible for the poisoning. ben ando reports. in brussels, the prime minister is asking for solidarity, not separation. last night the eu answered by withdrawing its envoy in moscow for consultations, sending, said theresa may, a message to russia. it is a threat to our values, and it is right that here in the eu council, we are standing together to uphold those values. earlier, at a press conference, the message hadn't been quite as decisive.

we will come back to the question. sergei skripal and his daughter remain critically ill, but police officer nick bailey, hurt after going to help, was well enough to be sent home from hospital. nick has had to undergo significant medical treatment, which has undoubtedly been very daunting for him and for his family. i have personally been amazed at the strength and resilience of nick. in brussels, the prime minister seems to have convinced britain's european allies to stand strong on russia. later today they'll be talking brexit, where she may be hoping for a softer approach. ben ando, bbc news. damian grammaticus is in brussels for us this morning. good the eu, damian. of course, we

saw theresa may manoeuvre her way through negotiations, trying to get support when it came to russia from eu leaders yesterday. today, the focus shifting perhaps more to brexit? yes, it will. it is worth saying that we are hearing from other who are arriving now on that russia question, we have heard from the lithuanian president and she said they were convinced by what theresa may said last night on the russia attack, the evidence that she presented, and they were convinced to strengthen their statement there, and suggestions that other eu countries may now follow the uk and consider expelling russian diplomats from their territory. we will then move on to brexit. theresa may won't be in the room but eu leaders are expected to signal the go—ahead for future talks on the future relationship. this is what theresa may said: it is important that we have made significant progress in the negotiations. the eu council will look to endorse the agreement

we reached earlier in the week with the eu about the implementation period. we have made good progress on the withdrawal agreement, but i am looking for a new dynamic in the next stage of the negotiations so that we can ensure that we do develop, that we work together to negotiate and develop that strong future economic and security partnership that i believe is in the interests of the uk and the eu. thank you. those endorsements expected from the progress mode so —— made so far, but also likely to bea —— made so far, but also likely to be a warning from other eu countries, a reiteration that the uk must agree to a workable solution to avoiding the imposition of border controls in ireland, between north and south, for this whole process to be completed by the end of the year. they will say this is a crucial part of the whole deal. this is made getting that consent, the guidelines from the eu countries for negotiators to start talking about future relations, trade relations,

that sort of thing... future relations, trade relations, that sort of thing. .. damian, thank you very much. profits at clothers retailer next fell by 8% last year. although the company made a profit of £726 million, lord wolfson, its chief executive, said 2017 was the most challenging year the company had faced for 25 years. it comes as a host of other retailers have issued profit warnings and plan to close stores. president trump has sacked his national security advisor for the second time in 14 months. general hr mcmaster will be replaced byjohn bolton. he has previously served as america's envoy to the un, and has backed carrying out attacks on iran and north korea. meanwhile, china says it's disappointed by president trump's announcement that he plans to impose tariffs worth tens of billions of pounds on chinese imports. the white house said the duties were necessary, and a retaliation for years of unfair competition from beijing. our china correspondent stephen mcdonelljoins us live from hong kong. tell us about the chinese response.

welcomer in this climate, with an ever more empowered chinese leader, xijin ping, ever more empowered chinese leader, xi jin ping, unencumbered ever more empowered chinese leader, xijin ping, unencumbered by term limits, you can't imagine him stepping back from a threat from donald trump, and that is the message we are getting from the chinese government. they say they don't want a trade war, but nor are they afraid of one. beijing says it is looking at imposing its own turrets on american fruit and nuts and steel tubing and wine and pork, but this was after the first round of us tariffs. now we have another fresh round of tariffs threatened against china, and we are yet to hear what beijing will do about this. at the moment, i think this is the first shot across the bow from the first shot across the bow from the chinese government. it will get

really serious if they start cancelling boeing jet orders or putting big tariffs on caterpillar heavy machinery or us soy beans. the chinese government knows it has some big—ticket items still up its sleeve, and it doesn't look like this will all end in a hurry unless both sides can somehow find a way to sit down and worked their way through their differences. stephen, thank you very much. a driver who hit speeds of 139 mph while fleeing police has been jailed for 21 months. rimell taylor led officers on a 12—minute chase along the a47 in wisbech in cambridgeshire. he was convicted for dangerous driving, driving while disqualified, being over the limit and not having insurance. we are told the invitations are in the post. invitations to prince harry and meghan markle's wedding have been sent out. do you remember sending your

invitations out and the excitement of getting replies? absolutely, definitely. i wasn't expecting the question. i am thinking about it from their point of view. we're talking about what they look. you are talking about what they look. you a re interested talking about what they look. you are interested in how many people will say they can't come. from the couple but my point of view, it is nice to get replies back saying that they can't wait. they have done quite a tricky thing here. they've been made using american ink on english card, and printed by a company called barnard and westwood. see what they did there? the couple have invited 600 guests, with a further 200 invited to the reception. lottie small is the printer, who has recently finished her apprenticeship, and was given the opportunity to make the invites. she used a machine, which she nicknamed maude, to print every invitation. on the assumption that most people

watching this morning are not going to go, we will tell you the dress code anyway. the dress code for guests attending the ceremony is uniform, morning coat or lounge suit, or day dress with a hat. that is obviously for the gents. may be. that is optional. where what you want. —— you can wear what you want. the weather with matt. sport relief is on today and we will be looking ahead to events happening throughout the day. we're now going to talk about obesity. obesity could overtake smoking as the biggest cause of death from cancer in the uk. a new study conducted by cancer research uk says more than 135, 000 cases of the disease could be prevented through lifestyle changes. other preventable causes of cancer include overexposure to uv radiation, drinking alcohol and outdoor air pollution.

joining us now is fiona osgun from cancer research uk, and david mclenachan, who was diagnosed with bowel cancer four years ago. good morning. how are you? nine good, thank you very much. can you give us the short version of your discovery that you were unwell to what happened ? discovery that you were unwell to what happened? i was fortunate because i reacted very quickly to some warning signs. i lost some blood and rang my gp straightaway. i was in the system very quickly. when you say you lost blood, did you have blood in your your in? —— you say you lost blood, did you have blood in youryour in? —— in you say you lost blood, did you have blood in your your in? —— in your your trying... blood in your your in? —— in your your trying. .. yes, that was quite shocking. it was an obvious sign and i rang my gp within an hour. by the

timel i rang my gp within an hour. by the time i got to the operation, i was still only a stage one, the earliest stage of bowel cancer, which meant that the treatment and recovery is much better. yours is one of the good stories around bowel cancer. when you hear this story about obesity, what do you think is the releva nce to obesity, what do you think is the relevance to either the way you were living before or how you are living now? you cannot help but think about the factors in your life that that might have affected your getting cancer. there was no genetic history. there were certainly things from my early years which i could have been a lot more careful about. had you been overweight? yes, overweight, and a poor diet, especially when i was a student. i definitely drank too much. there we re definitely drank too much. there were factors that might have contributed towards the bowel cancer. fiona, what can be done to change the message, or change what is sinking in to people now? we have spoken about smoking and the

campaign to warn people about the dangers of smoking, but obesity is kind of something that sometimes creeps up on you in terms of lifestyle changes. i'm sure, you know, david, you will appreciate that, and you said you drank too much at university, then you put on a bit of weight and don't think about it, then a little more creeps on. it's not something that you kind of turn around all of a sudden one day ago, i am obese and must fix this. it is difficult sometimes the people themselves to make changes. there are things that people can do in their everyday life: be more active, have a healthy, balanced diet. have lots of fruit and vegetables. we are told this message isa vegetables. we are told this message is a lot anyway, but it is the link to cancer now. and we know for a obesity that link is not known. it is only around 15% of people in the uk who are aware that obesity is a cause of cancer, so we uk who are aware that obesity is a cause of cancer, so we have a lot of work to do, which is why cancer research uk has been running a

national campaign to raise awareness that the link is there to help people understand that this is something that could affect their health in relation to cancer, because i think people often think of diabetes, heart disease, and they haven't quite made the link to cancer yet. we are also calling for the government to do more, because we know obesity is a complex problem, and while there are steps that people can take in their everyday lives, there is a lot we could do to make the environment we live in a much healthier, so we want to make the healthy choice easy, affordable one for everyone to be able to make those healthy decisions every day. we know the evidence from other studies is that we are getting more obese as a nation. younger people particularly at getting more of these, so that problem that we have clearly identified, the link with cancer, that willjust escalate if we stay as we are. yes, the rates of people being overweight and obese is definitely increasing. unlike smoking, where we

have a comprehensive set of measures, banning advertising etc, all of these measures go some way to helping the decline in smoking rates. we really need to mirror that and take some more comprehensive measures. david, can you take yourself back to your precondition, the person you were? if you had been sitting listening to this prior to your condition, do you think you would have just gone, your condition, do you think you would havejust gone, oh your condition, do you think you would have just gone, oh well, your condition, do you think you would havejust gone, oh well, it is just another statistic summaries telling me? i may well, i guess. most people don't think they are going to get cancer.” most people don't think they are going to get cancer. i was talking about how the message of smoking has sunkin about how the message of smoking has sunk in and people automatically say, you shouldn't smoke etc. what needs to happen everyday people to 90, needs to happen everyday people to go, that switch, has clicked? most people know in their family and close friends people who have been affected by cancer. so the message

really should get across, shouldn't it? you can improve the risk of cancer by doing everything a little bit better. you don't have to be perfect with alcohol intake or your diet. iam perfect with alcohol intake or your diet. i am certainly not. but i hope i have reduced the risk of a recurring. we are pleased you're well. thank you. here's matt with a look at this morning's weather. now look, it's getting better, and thatis now look, it's getting better, and that is a great picture, if you don't mind me saying. it tells the story in suffolk. it is a getting better day. grey skies for quite a few. this is what is on the way from any. a good deal of sunshine in topsham in devon at the moment. clear skies pushing on the satellite imagery. the cloud bringing the rain is here. for

england and wales, particularly in the next couple of hours, the thickest cloud, patchy rain and drizzle. occasional glimpses of sunshine. heaviershowers drizzle. occasional glimpses of sunshine. heavier showers to work across northern england. that links to what is happening in scotland and northern ireland. scotland in particular. lively showers in northern ireland accompanied by gusty winds. even here we will see improvement during the day. the same in northern england. more persistent rain in the far north and north—west of scotland. england and wales, more sunshine in the afternoon. the breeze easing down temporarily. rain in the isles of scilly and west cornwall for the afternoon. these early afternoon temperatures. not bad for the time the year. into tonight, we will see an area of low pressure which will push towards france. it will spill in rain and

drizzle. the cloud across england and wales keeps the temperatures up. clear skies in scotland and northern ireland, so some ice at the start of the weekend. a lot of dry and reasonably sunny weather to look forward to. wet weather not com pletely forward to. wet weather not completely out of the story. that is the case for a southern counties of england and wales to start saturday. the rain and drizzle should be light and patchy. it may stay grey in the south—east in the afternoon. elsewhere, brighter skies. showers breaking out. some of those showers heavy with hail and thunder. big gaps in between. temperatures in double figures. after a chilly night and a start to sunday, a better day for england and wales. the best of the sunshine will be around them. some isolated showers most will be dry. jaimes moran 13. scotland and

northern ireland turning cooler later in the day. a scattering of showers. the ones udc will be happy with hail and thunder. there are signs into next week of something much colder pushing away. some uncertainty at the moment. but some could see some snow. back to you. can you imagine a time where you get your weather forecast from dna? on noel. that would put me out of a job, wouldn't it? no, you would get all the information straight into you. we will find out. it is interesting, i think. we all know how important dna is to understanding human health. but now scientists think it could be used to solve another global problem — data storage. it may sound odd, but all those videos and photographs we love to take could one day be stored in the form of dna, saving huge amounts of space and energy.

that is why we are saying that matt could perhaps get his weather information. our science correspondent, richard westcott, explains. we are producing data at a staggering rate. all those videos, social media posts, online forms, and "look where i am" selfies. the problem is, it takes a huge amount of computer space and energy to store it all. so could the answer lie somewhere else, somewhere deep inside us all? i could not resist making a video of this beautiful replica of the famous watson and crick double—helix, their model of dna that changed the world. but what if i could store the video i am making now, onto a piece of dna? we take the movie file you sent me, which on a computer is zeros and ones, and we convert that into a, c, g, and ts. cambridge mathematician nick goldman has devised a way to turn computer

code into dna code. it means you can use the dna as a kind of hard drive. tell us about the day when you came up with the idea. the day was a big meeting discussing how we were going to keep on storing large amount of information coming from experiments on dna. we went to the bar and started talking about other ways we might store the information. and in a light bulb moment, we realised that the dna we'd been worrying about was itself a way of storing information. an american company turns nick's code into physical dna. it is a secret process, but they told us why it is so effective. so the first huge benefit of dna is that it's extremely dense. and if we stored all the data that is on the internet in dna, that would be the size of a shoe box. and then the second main benefit of dna is that it's permanent. you could store it forever,

which is very different from an electronic medium, which ages very rapidly. back at the wellcome sanger institute, in cambridge, they are world leaders in reading dna. these machines are scanning the code of everything from human beings to diseases like dysentery. and something hasjust arrived for us in the post. so this is what comes back from america. this is your report stored on dna. where is it? it's just there. the big question, then — did it work? could you read my video back? we put the file back together again and it's this file here. there it is. it does not look like there any errors in it at all. no, and we checked, and it's a perfect copy of the file. every single zero, every single one is correctly reproduced. big companies including microsoft are also looking at dna storage. it is still too expensive and too

slow, but that could soon change. in five years it will be advanced enough that, if you've got a lot of money and very valuable information, you might think about going this way. and maybe 10—15 years before there's a product that you and i would buy for our personal use. richard westcott, bbc news, talking to you from a piece of dna. richard westcottjoins us now. i like the idea that good ideas come out of the pub! very common in science! just clarify, this is not something that we will have within our own dna? it is not part of our make—up? we will not be carrying the information in our own selves?m make—up? we will not be carrying the information in our own selves? it is not human dna. if you think of dna as an instruction manual, your body

usesit as an instruction manual, your body uses it to build cells. it is the instruction manual. everything that is living uses dna as an instruction manual on how to build itself, like bacteria, diseases etc. it is the instruction manual that they are recreating, effectively writing in a lab in america. dna is made up of four molecules. if you put them in certain orders, these base pairs, you can write instructions. what they have been able to do is turn computer code, zeros and ones, into dna code. and effectively write their own dna. it is not living. it is not from inside a person but it is not from inside a person but it is still dna. i apologise, it still feels over here in terms of trying to grasp the concept. but is this something that is being picked up by big companies who see this as the future? they do.

they are looking for something to replace computer storage. i was walking around that data centre with my mobile phone. that is constantly gobbling up electricity. they have to keep it cool. it takes up space. this idea came out of trying to work out how to get more computer space in the room. they are storing dna data on those computers. they had that moment that the pub where they thought, maybe we can use the dna. the big differences you can fit so much onto dna. they say you can get all of the world's data onto dna and it would fit in the back of a van. microsoft is helping with development? there are lots of people looking at it. there was a big meeting in america a couple of weeks ago where they started to swap ideas. people have been toying with this for a couple of years. it is starting to build momentum now. yeah. i lose everything all the

time, so the thought of everything being in such a tiny thing, that is even worse. a little bit of dna in a great big box on your desk to reassure you!m is perhaps a lot to grasp this morning. time now to get the news, travel and weather where you are. a frost free start to the day. it is a dampener. heavy rain across northern part of the uk which will ease away, with sunny spells developing for many into the afternoon. that low pressure area

will clear. in the afternoon, the next area of low pressure will slowly move its way in towards the south and west. the cloud will increase here later on. the rain will ease in the afternoon for scotland, northern ireland and northern england, just one or two mag showers. some rain spreading its way into the isles of scilly and cornwall, but sunny spells for many and temperatures of 11—13dc further south, chile in the north compared to yesterday. 7—9dc here. through the night, the rain will continue to spread sporadically north and east, some heavy bursts, perhaps, but very patchy rain, really. temperature no lower than 4—7dc. in northern ireland and scotland we will see a frost at the start of the weekend. the weekend will see bright and sunny weather with a few showers.

temperatures average for the time of year. saturday starts cloudy with a few spots of rain across england and wales, which will clear to the south—east, perhaps lingering for a while in the far south—east. temperature wise, 8—12dc. ron sunday, a drier and brighter day, lots of sunshine across the uk. again, just the odd shower here and there, wintry over the high ground of scotland. in the sunshine, temperatures into double figures across temperatures into double figures a cross m ost temperatures into double figures across most areas. 13 degrees in the south—east, which will feel pleasant. then it will get colder again into next week. goodbye. this is business live from bbc news with jamie robertson
