and one museum in the us now wants to put these two breakthroughs side by side, displaying the whitest possible white alongside the blackest black. victoria gill, bbc news. time for a look at the weather. here's tomasz schafernaker. dults from six different households so if people come to beautiful parts of the countryside like this they are being urged not gather in large numbers and if a beach is busy to go elsewhere. all right lorna, thank you. lorna gordon there. . do we have much need in this country for that bright white paint? it is still a little bit too cool for that, we want the warmth but it is going to be a very bright weekend, so it is good news i think on the weather front for most of us. the mornings will be on the chilly side but i think the temperatures will rise by a few degrees during the afternoons. the settled weather is thanks to high pressure which has extended from scandinavia. it is stopping the weather fronts from moving in. this is the satellite picture with a weather frontjust to the west of us, i have added the

wind speeds, the average wind speeds, we are only talking about s—iomph worth of wind which is a slow wind overall. and despite the temperatures being say round 10 degrees it feels pleasant enough. we would like the temperatures to be a bit higher, but it psi what it is. through the course of this evening, and overnight. not much changes on the weather front, we and overnight. not much changes on the weatherfront, we have and overnight. not much changes on the weather front, we have light winds and clear skies so will will be a touch of frost but in the west it should be frost—free. belfast 6 degrees overnight and seven in the western isles of scotland. that is because this weather front is hugging the west of the british isles here and there is just somewhat of a southerly breeze here bringing the cloud and bits and pieces of rain. you can see that breeze on the weather map here, whereas to the east central and eastern areas calm, clear skies, it is going to be a very pleasant day on saturday for some of us, up to 14

degrees, maybe even 15 in some areas of the uk, so a decent day on the way there. now sunday, the weather fronts come close, in fact they start to brush northern ireland and western areas of scotland, so admittedly, on sunday it is not going to be quite so sunny here, in fact a few spots of rain expected and that shield of cloud will engulf areas to the east. east. sunday we will call it bright rather than sunny but the temperatures respectable, 14, 15 for some of us. notice the milder yellow air is with us on monday, and tuesday. but, at this stage it looks as though from wednesday, we pick up a northerly again, from the arctic, so we will see temperatures briefly rise, to the mid teens, into next week but then from tuesday and witness on wards it looks as if they are going back down again. that is still a while off. let us enjoy the fine

weather this weekend. let us enjoy the fine weather this weekend. a reminder of our top story. final preparations are being made for the duke of edinburgh's funeral, which will take place tomorrow in windsor. the tomorrow in windsor. archbishop of canterbury wil lead the archbishop of canterbury will lead the service. she the archbishop of canterbury will lead the service.— the archbishop of canterbury will lead the service. she is the queen. she will behave _ lead the service. she is the queen. she will behave with _ lead the service. she is the queen. she will behave with the _ she will behave with the extraordinary dignity and extraordinary dignity and extraordinary courage that she always does. and at the same time she is saying farewell to whom she was married for 73 years. that's all from the bbc news at one, so it's goodbye from me, and on bbc one we nowjoin the bbc�*s news teams where you are.

good afternoon, i'm chetan pathak with your latest sports news. england all—rounder ben stokes is going to be out for up to 12 weeks after an x—ray and scan showed he needs surgery on a fractured finger. it means stokes will miss the test series against new zealand — and is also a doubt for england's white ball games against sri lanka and pakistan later injune. stokes was injured whilst playing in the indian premier league earlier this week and will fly home tomorrow with his surgery set for monday. england under—21 manager aidy boothroyd is stepping down after four years in the role, just two weeks after the side finished bottom of their group at the european championship. england were one of the favourites for the tournament with a host of big name players to pick from, but went out following defeats to portugal and switzerland. pressure has been on him with one of the most talented groups the nation has produced in a very long time.

pressure has been on him with one of the most talented groups the nation has produced in a very long time. he had access to players like mason mount, phil foden, jude bellingham and trent alexander—arnold. but boothroyd has said his job is to not win trophies, but to give players to the first team — that led him to describe the under—21 job as an impossible job. next, it's fair to say there,'s still no love lost between paul pogba and his former manchester united bossjose mourinho. the pair fell out during their time at old trafford, and now pogba's criticised mourinho's man management style — accusing him of "going against players" and making them feel "like they don't exist any more". the comments come just a week after united beat mourinho's tottenham side to increase the pressure on the manager. pogba's former manchester united team—mate chris smalling and his family have been the victims of an armed robbery at their home in rome, where he now plays. three armed men entered the premises and forced the former united and england defender to hand overjewellery and precious items before leaving.

there's a setback for scotland ahead of this summer's euro 2020 after rangers midfielder ryanjack was ruled out due to a calf injury. he played a big part in the play—off win over serbia, but rangers manager steven gerrard has confirmed jack needs an operation which will see him miss scotland's first major men's tournament in 23 years which includes a group game against england at wembley. the world 100 metres champion christian coleman has had his two—year ban for missing three drug tests reduced by six months, following an appeal to the court of arbitration for sport. the 25—year—old american will still miss the tokyo olympics starting injuly, as the ban runs until the middle of november. thereafter he'll be able to return to defend his world indoor and outdoor titles in 2022. mercedes driver valtteri bottas was fastest at the end of an incident—packed first practice at the emilia romagna grand prix at imola.

bottas finished four hundreths of a second ahead of his mercedes team mate lewis hamilton. max verstappen third. but it wasn't so good for haas's nikita mazepin, his session started with a spin and ended with one here. elsewhere red bull's sergio perez and alpeene's esteban ocon collided, causing the session to be stopped for a while. and the second practice session has just got under way at imola, you can follow it over on the bbc sport website. there you'll also see that the british number one dan evans is taking on david goffin in the quarterfinals of the monte carlo masters, he lost the first set 7—5 and has just taken the second set 6—3. 1—1 in the decider.

i'm jane hill. 77 cases of the coronavirus variant first detected in india have been identified in the uk. 73 cases have been confirmed in england as well as four cases in scotland. india's covid rates are soaring with almost 14 million confirmed cases but the country isn't currently on the uk's travel red list. earlier my colleague martine croxall spoke to paul hunter, professor in medicine at the university of east anglia, who said there may be questions about the variant�*s resistance to vaccines.

india itself is seeing a pretty dramatic increase in cases at the moment and it has since the beginning of march. and we don't know for certain that this variant is what is driving that, but it is certainly possible. the other thing is that this variant has possibly two escape mutations. and an escape mutation is one that makes it a bit more resistant to immunisation and it is plausible, but we don't know for certain, that two escape mutations would make the but we don't know for certain, that two escape virus even less susceptible to vaccines than the south african and the brazilian variants are. this is what we see with coronaviruses, they accumulate escape mutations and move from immune control over a number of years. so it is worrying, but it is still early days to be certain. what is different about this particular variant compared with the others that we know about, such as the one from brazil and south africa? it actually has a very different history to the others, it seems to

have split from the main variant that was circulating earlier, before the kent variant split off the evolutionary chain. the two mutations, you have heard about the e484k mutation, the south african and this is a cube mutation. it is the same place, but a different mutation. it has also the l452r mutation, that is similar to the one in california and that has possibly been associated with the surge in cases in the west coast of the united states. so it's got two variants, two mutations that worry us about resistance to vaccine and possibly also increased infection.

—— increased infectivity. what does this mean for the vaccines that we already have and the likelihood that we will need more to cope with these variants? well, i think we have already heard, we heard from the chief executive of pfizer yesterday that he reckons that we will need to be giving out further boosters of the vaccine come the autumn. that is primarily to control against the e484k mutation with the south african and brazilian variants, the fact that we have this other variant means we will have to add more variants to the vaccine mix that will come out towards the end of the year. yes, we are likely to need further vaccine development and in the meantime hopefully the vaccines will still remain effective at reducing the risk of severe disease, but i think we can't be complacent about that.

talks on post—brexit trade to northern ireland have seen some positive momentum but difficult issues remain, according to the uk's chief negotiator. lord frost said that intensive discussions between britain and the eu had begun to clarify the outstanding issues and that there should be more contacts at all levels in the coming weeks. ukraine says russia has served notice that it will close part of the black sea to military vessels from other countries from next week. ukraine's foreign ministry called it a gross violation of the right to freedom of navigation guaranteed by the un. later today the leaders of france, germany and ukraine will discuss the escalating tensions in eastern ukraine and the massive russian military build—up along the border. the bbc�*sjonah fisher reports. these trenches are the ukrainian military�*s front—line positions in eastern ukraine. now, the russian—backed forces

are about 100m or so away from here. we could actually hear them a little bit earlier, chopping wood to burn on their fires to keep warm. now, this conflict line has been pretty quiet for the last few years. it's hardly moved on the ground. but the mood here has significantly shifted over the last few weeks. and the big reason for that is that russia has deployed a large amount of both personnel and equipment on the russian side of its border with ukraine. and that has triggered fears, concerns here in ukraine, that this war, which has been pretty quiet for the last several years, may be about to enter a new phase, possibly even that russia might be considering some sort of invasion. russia, for its part, has played it all down,

said it is perfectly entitled to move its troops where it wishes within its own country, and that its redeployment towards the ukrainian border is part of a military exercise, and that there is nothing more sinister afoot. but the shift both in terms of the troops and in terms of what's happening on the ground has certainly got people here worried, and i think a lot of people are asking the question of, what exactly is russia up to? what exactly is it trying to achieve here? the headlines on bbc news: final preparations are being made ahead of the duke of edinburgh's funeral, which takes place at st george's chapel in windsor tomorrow afternoon. police in chicago release film of the moment an officer shot dead a 13—year—old boy in an alley last month.

monkey embryos containing human cells have been made in a laboratory by us and chinese scientists. the experiment has raised serious ethical concerns but researchers involved say their work could address the shortage of transplantable organs, and help understand more about human disease progression and ageing. the developing embryos were studied for up to 20 days before being destroyed. for many people living in england, this weekend could be their first chance for a getaway since last year. that's because self—contained accommodation was given the green light to reopen this week, following the latest easing of lockdown restrictions in the country. sarah corker has been speaking to those in the industry about the rise in popularity of staycations. caravan sales have gone through the roof. more of us are booking holidays in the uk so manufacturing firms that supply

the tourism sector are busier than ever. what's demand been like over the last 12 months? phenomenal. ever since about lastjulywhen the world opened up and people could go on holiday in the uk. in the autumn, our sales team processed an entire year, an entire ordinary year's worth of sales in six weeks and i guess the other thing to say is that we are 75 years old this year and it's never been busier. hull is the caravan—making capital of britain. here in east yorkshire the industry employs more than 10,000 people and this company is taking on more staff to keep things moving. are you seeing a change then in the types of people holidaying in this way, perhaps for the first time? the answer is yes. so we've seen a large influx

with younger families looking to just enjoy a good holiday, often going in and hiring a home. from holiday homes in yorkshire to glamping in gloucestershire. this couple opened their business during the pandemic. it's aimed at those wanting to escape to the country. what the pandemic has done is rehighlighted the beauty of the british countryside. we've got lots and lots of londoners. a lot of the people who live in the cities who have got no outside space, the first thing you want to do when you are let out his go somewhere that is completely —— when you are let out is go somewhere that is completely different and maybe

banned from the race after his conviction was upheld. but like a cat with nine lives, there's yet another political door supreme court confirmed a decision made in march to annul his corruption convictions. the president certainly counting him as a candidate but not without firing a warning. translation: if lula comes back by legal | and auditable vote, that's fine. now, look at brazil's future is going to look like with the kind of people he'd bring into the presidency. if the two equally polarising politicians go head to head, it's sure to be an explosive campaign, one a leftist icon seen by detractors as a symbol of corruption at the very top, the other a far—right populist at the centre of a political crisis in a nation ravaged by the coronavirus pandemic,

an issue the election campaign is bound to be fought on. tanya dendrinos, bbc news. a man from doncaster is raising money for the hospital that saved his life. fraser lamb was born with spina bifida which occurs when a baby's spine and spinal cord does not develop properly in the womb. he had to have life —aving surgery at sheffield children's hospital when he was 12 years old. and to say thank you, he's now started a very special fundraising campaign. mark ansell has the story. go, fraser! one thing fraser can be sure of when he clocks up the miles in bawtry is the backing of his village. he is pushing 2,021 miles in and around bawtry in the year 2021, to raise money for sheffield children's hospital charity. the support i get is unbelievable. every day, there's somebody that's cheering me on

or peeping their horn at me. it's more than i ever could have imagined. he'sjust a brilliant individual, an inspiration, i think, to everyone out there. we've seen him out, i say, in rain, torrential rain, sleet, snow, wind. he just never stops. fraser was treated at sheffield children's after he was born with spina bifida. then, 12 years later, he collapsed and needed life—saving surgery at the same hospital. i'm here today because of them. the hospital will always

have a special place in my heart. mike clement has set up the fundraising challenge. he's in awe of his friend fraser. it's a real challenge for somebody to push themselves that distance, have to go out every in all weathers, all conditions. the support of the local community has been brilliant but i think his confidence has grown as well as his fitness as we've gone forward. it's been a tough challenge for fraser, pushing an average of six miles a day. what keeps you going day after day? knowing that i'm going to make a difference to people's lives. fraser will keep rolling on in 2021 until he completes his mammoth challenge. mark ansell, bbc news, bawtry in doncaster. you might remember this time last year, when the netflix documentary tiger king became a viral sensation. well, it turns out that keeping big cats as pets is notjust popular in the us, but in russia too. a warning in advance: don't try this at home. eliza craston reports. a wild cat, eyes fixed on someone asleep. but this is play, not prey.

the unexpected, a hug. meet the world's most unusual house cat, messi the puma. he lives in this apartment in the russian city of penza, with his owners, alexandr and mariya dmitriev. translation: i'm attached to him l as much as he's attached to me. | we have this very strong bond with each other. when, for example, i leave home, the cat doesn't want to go out of the house. he doesn't eat, he's very worried, and always meets me when i return home. the couple found messi as a cub at the zoo. he was unwell, so the zoo agreed to their request to take him home. he is still small for a puma, but they say he is now fit and healthy. like a dog, he has a collar and a lead, so he can be taken on walks.

but a pet puma is not the same as a pet dog. translation: if you live with such a predator, - then an attack is inevitable, because sooner or later, when the puberty begins, he'll be sorting out who's in charge in the house. alexandr says, like in the animal kingdom, it's all about marking territory. translation: i proved myself to be a more dominant male than him. - he accepted this position and since then we've been living without fights, having mutual understanding. activists say keeping wild animals as pets is cruel and that they should be in centuries of reserves rather than small spaces like this. and then there's that key question, and big cats like messi ever truly be tamed? eliza craston, bbc news. —— can big cats like messi

ever truly be tamed? now it's time for a look at the weather with tomasz. the weekend weather's looking pretty good for most of us. the mornings will still be a little on the chilly side but here's the good news — the afternoon temperatures will pick up a little bit, perhaps into the mid teens for some of us. now, the settled weather is thanks to high pressure centred over scandinavia, it's actually extended into the uk and many western and central parts of europe. the winds are light as well, four orfive miles per hour worth of wind, hardly anything at all, and then you add the strong april sunshine, it doesn't feel too bad at all despite the temperatures only being around nine to 12 degrees. if you are in the breeze and on the north sea coast it does feels chilly but out towards the west where the winds are light it feels ok. through this evening we expect clear skies across

the majority of the uk and overnight. there will be a frost again in and overnight. central and eastern areas but out towards the west where we have more of a southerly breeze and a bit more cloud it should be frost—free for places like belfast. that's becaue there's a weather front brushing the very far north—west of the uk and the high pressure extending into england and wales but closer to northern ireland and western scotland we have weather fronts here and bits of cloud and spots of rain to come for the weekend. saturday for most of the country looks absolutely fine from the isle of wight to with sunshine all round and best temperatures across more western areas such as 1a in liverpool and belfast. you can see on sunday the weather fronts are still in the same place, sort of sliding towards the north—east here with the high pressure dominating the weather across the uk. but it does mean it may turn damp in parts of northern ireland and at least the western isles as we go through the course of sunday and generally speaking more

hazy skies across england. temperatures 1a or 15 celsius. if the sun comes out for any length of time it shouldn't feel bad at all. i say it's turning slightly milder but look what happens on tuesday and wednesday, we develop a northerly wind again so it does look as though the middle of next week after this brief warming to 1a, 15, maybe 16 degrees, the temperatures are going to go back down again.
