good evening this is your update from the bbc sport centre. this year's six nations rugby championship kicks off this. and while the players will be focussing on what happens on the pitch officials are having to tackle numerous problems off it ranging from allegations of sexism and homophobia to corruption. our sports editor dan roan explains. with its blend of rivalry, tradition and passion, the six nations remains one of the highlights of the sporting calendar.

but with a world cup looming, the start of this year's championship is a timely boost for a game in need of a lift. 2003, and england win the grand slam. sensational finish! before going on to claim their only global crown. 20 years on, new head coach steve borthwick is tasked with rediscovering such glory, starting against old rivals scotland. there's few fixtures in world rugby that have the ability to excite people more than this fixture. i'm looking forward to the loud, packed twickenham this weekend. and england supporters are going to be cheering on this team. england have lost twice in a row against their opening opponents, scotland — last year's defeat at murrayfield the start of a disappointing campaign that saw them finish in third place under the recently sacked eddiejones. but now there's added turmoil here in the community game — amid mounting concern over head injuries, the rfu has apologised for its handling of a rule change lowering the tackle height. the members of this club near manchester, like many others across england, furious at what they see as a lack of consultation. a lot of the players are thinking, where's it going and is it worth playing rugby any more? because it is a fundamental change

to how we play the game, how we got brought up to play the game, and how the guys have been playing it for the last 30, 35 years. so there's a lot of unhappiness. facing a grassroots revolt, litigation over concussion and mounting concern over professional club finances, this weekend's calcutta cup match here at twickenham can't come soon enough for the beleaguered rfu, but they're not the only rugby union facing a crisis off the field. the six nations gets under way in cardiff, where legendary coach warren gatland starts his second stint in charge of wales. but his return has been overshadowed with the welsh rugby union engulfed by allegations of sexism, racism and misogyny. aired in a bbc wales documentary. bosses today facing questions on the scandal in the senedd. it's possible for things to occur over a period of time and for people to turn a blind eye. i think as an organisation we have been in denial as to the extent of the problem. but away from the controversy, wales can at least look forward to hosting ireland —

now the world's top ranked team. and with in—form france defending their crown, the game's authorities will be banking on a classic six nations to put the focus back on the pitch. dan roan, bbc news. charges of rape and assault have been dropped against manchester united player mason greenwood. the 21—year—old had been due to face trial in november over allegations of attempted rape, assault and controlling and coercive behaviour, which he denied. the crown prosecution service said the charges were discontinued after a key witness withdrew their involvement. greater manchester police said it was "only fair" to announce greenwood would no longer face criminal proceedings. in a statement manchester united said that they... new everton boss sean dyche has been speaking to the media for the first time since replacing frank lampard.

the club are 19th in the premier league with just three wins, and 15 points from 20 games. dyche said he wants their fans to believe in him. it is easy to take the wheel of a ship in calm water, but not so much when it is choppy waters. we want the fans to play their part in that. the club is not where it wants to be, but we want the fans to join in and reconnect with us. it is easy to say, i have got to earn my spurs, i understand that. i am a bit of a marmite manager anyway, but i am willing to put the hard yards into earn their respect. chelsea manager graham potter said he's "excited" about the challenge his bigger squad will bring, after the club spent more than £300 million injanuary. the blues signed eight players during the transfer window. including a british transfer record fee for world cup winner

enzo fernandez from benfica. but under uefa rules, only three can be added to their squad for european fixtures. challenge is the right word. certainly not complaining about it. it's exciting. it's a test for me, of course and for the staff and for everybody. but it's an exciting one. with a lot of really good players. we've got a lot of really good players. we have to create an environment where there is competition, where there is healthy competition and they can push each other. and at the same time understand there's going to be frustration at times. not everyone can play, that's reality of where we're at. it's fuelling the conversation because only 11 can play. there will always be ones that are disappointed. and finally... he's barely been retired from football for a month but already gareth bale is back demonstrating his sporting prowess. 0n the golf course. he's taking part in a pro am in the united states and made this remarkable recovery at spyglass hill. bale�*s taking partjust 23 days after quitting football — a career which saw him win 5 champions league titles, and become wales�* all time top scorer. the field also includes former american politician condoleeza rice

and actor bill murray. that's all the sport for now. now, you may have heard of chatgpt, it's a popular online chat bot which is powered by artificial intelligence. and you can ask it to write essays for you, right computer code, even give you creative ideas. it was developed by the american company open ai chatgpt is and chatgpt is trained on the internet so it can understand and generate humanlike tax. ——text sounds too good to be true? is prompted concerns and some academic circles that students could use it to plagiarise their essays. in fact, chatgpt has already obtained good passing grades in a medical

licensing exam and also a master in business administration paper. it slid a princeton university student to create gpt zero. now, that's a programme that can spot when iai has can spot when ia has been used our technology correspondent zoe clement explains how all this works. i think that thing to bear in mind about chatgpt is that it is extremely good at what it does. it answers queries. based on everything that was on the internet up to the year 2021. so it's not live connected, it can't tell you about current affairs, and i can't for example give you the time. but what it can do is give you a pretty solid answer to pretty much any question. it can also do that in the style of anything you want. you can ask it to write a song in the style of taylor swift or write an introduction in the style of a tv news presenter. you should be worried because it doesn't extremely well. it's probably best for me to show you this in so here is a video from a little earlier.

first question, explain chat gpt in two sentences. chat gpt is a chat bought trade using the gpt three language model. it uses natural language processing to generate responses to user inputs in a conversational manner. not so conversational so far. let's try another question. are you alive? no, i'm a virtual assistant created by a computer programme. i do not have consciousness of the ability to feel emotions like a human. i exist only to provide information and assist with task within the limitations of my programming. zoe, that is absolutely extraordinary. some deep questions there. but in terms of you saying i should be worried, i am worried. i'm not the only one that's worried though. just talk us through the concerns with this. there are a few issues with it. number one, it is so good that there are already examples of students using it

to write their homework for them. if i was a student right now i think i be delighted to know that you could literally say, write me 500 words about the end of the second world war and you will get them in about a minutes�* time, undera minute. teachers are saying well, we can spot text that's plagiarise for the internet because itjust doesn't sound like the voice of a student. we think we can tell. it's difficult to know because will never know the ones that they don't catch. there are also concerns that people could use it to write university applications for them. that it could completely change the model we use currently to test peoples abilities and achievement. the other concern is that it doesn't tell you where it's got information from. they presented all as fact. so it can very easily spout out misinformation that it has found somewhere on the internet and it wouldn't necessarily warn you that it might not be true. thirdly, there are cybersecurity experts who are warning that it can be manipulated into writing malware, computer viruses, which is also potentially a very serious problem

if it actually happens for real. so, the concerns are pretty stark, actually. it feels too good to be true. there are concerns around it. butjust in terms of being able to spot it, there is a programme that has been written, i mentioned at the beginning to potentially spot it in order to work it out. but this is a chat bot that has been banned in some countries because people are so aware of the concerns it raises. that's right. 0pen ai itself launched on tuesday which says it can spot tax that's been written by humans and text that's been written by artificial intelligence. now, that something that i think quite heavily needs to be put to the test. it is being used in lot of positive ways as well. lots of people are using it to write things like marketing copy, website copy. it's not all bad news. it's potentially the future of search.

some experts are saying rather than put in a query into a search engine and get of links to wage your self through, why notjust ask it a question and get one distinct answer? it's going to save you a lot of time. and be a lot better to use. for that reason there are lots of people chasing this. google is also working on a similar language model. you may remember this one because one of the engineers on this said it was so good he thought it was sentient. now, google fired the engineer and it has always denied this claim. but it gives you in example, doesn't it? 0f hey, how good they are nb, how useful they could become. microsoft for example has said that it's going to invest billions in open ai, the company behind us. it obviously also can see its enormous potential. we're only on generation three, version three of chatgpt and millions of people are using it and are very impressed with its result. when version four comes out and open a i says it's working on that now

we're going to see even more marked improvement. i think you have to bear in mind with these things, they've been around for a long time, open al was set up in 2015. they've been working on it quietly for seven yea rs. it's only now that we're seeing the fruits of that labor. it might not surprise you to know that one of the co—finders at the beginning was elon musk. he's no longer involved in the project but he says he knows about it. now here on bbc news it is time for click.

the uk's first space launch was here in cornwall. that is because that is where the earth is spinning fastest, so as you launch, it gives you an extra whang. and that is why the uk space port is way down south in cornwall. and that is why it was there, earlier in the year that virgin 0rbit attempted the first satellite launch from uk soil. marc cieslak: the uk's first functioning spaceport is here in cornwall. we are creating a huge cluster of space technology. the global value of the space economy is somewhere in the region of $360 billion. to the uk it is 16.5 billion

pounds every single year. newquay airport usually hosts small passenger and private aircraft but is now home to spaceport cornwall. rockets will not launch from the ground here. private companies instead will take advantage of the runway which is one of the longest in britain, and ideal aircraft but is now home to spaceport cornwall. rockets will not launch from the ground here. private companies instead will take advantage of the runway which is one of the longest in britain, and ideal for an innovative method of satellite deployment via a rocket called launcher i, courtesy of a company called virgin 0rbit. it is no ordinary rocket launch. this converted 7a7 carries a rocket underneath its wing which has nine microsatellites inside. the aircraft will take off from here and fly out over the atlantic and ascend to an altitude of 35,000 feet where the rocket will detach and blast off to the edge of space and deliver its payload. the bbc has been granted exclusive access on board cosmic girl. this aircraft used to be a virgin atlantic airliner but it has been specially modified so it can launch rockets. in its former life this cabin would have been filled with rows and rows of passenger seats as well as galleys and bulkheads and they used to even have a bar on these aircraft. all that has been stripped out to save weight and

weight—saving is really really important if you want to launch rockets. the squadron leader, matthew �*stanny�* stannard, is on loan to virgin 0rbit from the royal air force. he has already played a role in three successful rocket launches from cosmic girl over the mojave desert in the united states. can you take us through a mission and how it works? we get airborne from the runway behind us, and head out to what is called a race track, the point where we will drop the rocket. that phase is called captive carry, we're just looking after the rocket, making sure it is healthy, using launch engineers in the back and mission control on the ground. we commence about 2g, so if you are a passenger on this aeroplane, you feel yourself being pushed down slightly on the seat, and we go to about 35 degrees, nose up. and what we do is we try to transfer energy from the aeroplane to the rocket. by us going to that, the moment the rocket comes off it's heading off to where we want it to and not wasting any fuel.

when we get to about 35 degrees nose up, we get to the right speed and the copilot will press the button to release the rocket. at that point the aeroplane is all the way over to the right side, and we're going to watch the rocket head to space. our system is portable. it is an airplane with a rocket and a few skids with equipment on it. so we can move it anywhere. we can enable space launch anywhere, any airport that can handle a 747. there is a growing space economy here in the uk. the uk has been a leader in small satellites which is where the satellite market has drifted to. some people may argue that there are many problems, down here on earth, lots of massive economic problems going on on terra firma, why should government and nations, why should people be concerned with what is happening in space? if you look at the discussion about climate change, how do we know

about climate change? because we have seen from space, changes in our atmosphere. we can detect the chemical compositions and we are looking at where the pollution sources are now. methane is now being detected for the first time. while cosmic girl is changing the way satellites are launched into the heavens, this spaceport here in newquay could change the economy in this particular part of the world. the local council here has invested £5.6 million, overall the spaceport has a £20 million pricetag. it is a gamble for an area where mining and fishing were the traditional industries, now replaced by tourism. we're creating 150 directjobs related to this amazing facility that we have built here at spaceport cornwall and we plan to create another 240 jobs in the supply chain. this is in a high—tech futuristic innovative sector. we are trying to bring a new industry to cornwall to develop jobs in a new way and develop the skills

base as well. the low earth orbit economy as i describe it is definitely one that is growing. there were 1700 small satellites launched into low earth orbit last year. 0rbit�*s maiden uk flight took place injanuary nine, 2023. the plan was for launcher1 to deploy nine micro satellites into orbit. things did not work out like that though. after a successful takeoff the rocket launched from cosmic girl, and as it reached space it all looked good but at an altitude of 180 kilometres the rocket experienced an anomaly, and the mission abruptly ended. its satellites never achieved orbit and the rocket components fell back to earth in what is described as an approved safety corridor. cosmic girl landed safely. 0rbit�*s next launch will be back over the mojave desert. it is investigating what went wrong in the skies above the uk and the company says it hopes to attempt another uk launch later this year. the uk space race is now on.

two conventional vertical rocket launch facilities are being built in scotland. the prize of getting a satellite into orbit from uk soil is still up for grabs. while on our recent us travels i got hands on with some of the latest kit to make your house a smart home. for some of us wanting to smarten up our homes we do not want to add a lot more devices. certainly not ones that look obvious. so the mui board here is based around the idea of calm technology, something that has functionality without being in your face. when it is launched later this year it will be based on the matter platform that can be connected to different smart home devices and then you have the choice of which ones you want listed when you bring it to life. you could have a weather forecast, if you want to set

a timer for your lights to go off you can do that by drawing a line here and you can see the time going up and then watching the line disappear as the lights go out. i don't know about you but i cannot start my day without coffee. so this is of particular interest to me. it may look like an ordinary pod machine but the morning is all about making gourmet coffee and getting it just right. using this dial you can select the temperature, pressure and amount of coffee that you are making. there are a couple of presets but otherwise you can be absolutely specific about what you are after and you can also do that within the app. and if you were wondering how you will know what settings to use, an assortment of coffees from around the world have their instructions programmed in. there is momo coffee, roasted in korea. it should be brewed at 92 degrees.

let's put a pod in. this one will vary the pressure depending on what the coffee needs. sometimes it has low pressure at the beginning and builds up towards the end. and now for the big test. the flavour. the taste is intense, kind of nutty without comparing it to making one in my regular pod machine i guess it is tricky to say. oh, no, i spilt my coffee! lucky i have this robotic vacuum and mop here. florio, do your thing. florio: robot is repositioning. like other similar robo cleaners, this mop and vacuum in one maps out its route, using what it calls neural vision navigation.

so some cameras and sensors collect data for an algorithm to make sense of. it then sends a floorplan to your phone where you can make sure it's right and set any rules you may want for each room. 0h, kitty, you will be all right on the floor won't you? and of course, it has the obligatory obstacle avoidance. it managed to move really closely around her without even stroking her fur. it also has a dynamic scrubbing function, the equivalent of a bit of elbow grease and when it detects a carpet or rug it will automatically lift up the wet clean function by two centimetres and moved to vacuuming. what is different about this device is there is no dirty water that needs to be cleaned out and in fact it automatically changes the pads on the mop. and you can even assign it to do that room by room. meanwhile, it is time for some food. i will be testing the pronto pressure cooker which also has an airfryer attachment which goes on top. this is just an aesthetic prototype at the moment so it

doesn't do anything, but the idea is when there is a working one it will make the food crispy as well. the whole system is connected, there is a device here as well as the option to use the mobile phone app, but there is a whole range of recipes and you can even have live cooking lessons. so for the sake of filming i have put this to the test by making some saute potatoes, its multiple cooking modes mean you can bake bread or roast a chicken, saving the energy of a full oven. and it is done. in this particular instance it is probably not really any more useful than a frying pan, in fact probably more hassle, at least there is a lot of versatility in what you can do here. and it still looks tasty. so whether it is for eating, drinking, resting or cleaning, there are some of the latest devices that you never knew you needed. i'm afraid that is all we have time for. the full—length show can be found on iplayer. see you soon. bye— bye.

hello there. with temperatures widely up into double digits, thursday was an unseasonably mild day. and it is set to stay that way certainly for the next couple of days. friday's weather chart brings this weather front northwards and eastwards. it will bring some cloud, it will bring some patchy rain, and behind it a resurgence of mild air. in fact, friday could be an even milder day. but where we have that weather front in place, it will bring some cloud, some outbreaks of patchy rain northwards and eastwards across northern england, and scotland, south—west scotland and north—west england likely

to brighten up a little through the afternoon. northern ireland, wales, the midlands, the south of england should see some spells of sunshine, often some quite large amounts of cloud, but temperatures as high as 13—14 celsius. and we will start the weekend in that mild air. again, quite a lot of cloud around, some sunny spells. however, this band of cloud and rain will be sinking its way southwards and eastwards, and that will bring a change, because that is associated with a cold front, you can tell that from the blue triangles here, and behind that, as the name suggests, the air is set to turn colder for sunday. but at the same time, we see this strong area of high pressure building its way across the uk. so while it will feel chillier on sunday, it should look brighter. remember, when you look at our maps and you don't see cloud, that is where we are expecting sunshine, and there should be plenty of it on sunday. bit of cloud perhaps lingering in the far south—west of england and in the far north of scotland. temperatures down a little, but 8—9 celsius, that's certainly

isn't anything unusually cold for this time of year. now, our area of high pressure will still be with us as we move out of sunday and into monday. there could well be a frost on monday morning, maybe some fog patches too. the centre of that high perhaps drifting a little further south—eastwards, allowing more cloud to filter in to northern ireland, western scotland, maybe western england and wales as well. and those temperatures generally around 8—10 celsius. now, this area of high pressure is going to be a big feature of the weather throughout next week. as we move in to tuesday, this frontal system tries to push in from the west, but because of our area of high pressure, that'll tend to squeeze the life out of the weather front, so not much left on it, really, by tuesday, just a band of cloud, maybe some bits and pieces of rain, sunny spells elsewhere, and those temperatures around 7—9 celsius. now, as we look further ahead, it is likely that our area of high pressure, certainly the centre of the high, will tend to slide eastwards out

into continental europe, but depending on exactly where it ends up, well, that will determine just how chilly things will become as we go through next week. it may be that the area of high pressure ends up a little further north than we have on our chart here, and that would allow us to tap into some really cold air from eastern europe, but the most likely scenario is that the high tends to drift towards the south—east, and we end up with more of a south or south—easterly wind, which at this time of year will neither be particularly mild nor particularly cold. so, as we look through next week, one thing we can say is that it will be largely dry, with our area of high pressure close by. frost and fog likely to develop, and it will be a little chillier, at least for a time, but there's still a bit of uncertainty as to just how much chillier it will become. that's all from me, bye for now.
