this is bbc news. the headlines: why the man often called the �*godfather of artificial intelligence' has quit his job at google. if you had 10,000 people and whenever one person learns something, everybody automatically knew it, that is how these chat apps can't know so much more than any one person. almost half—a—million sudanese have fled their homes since fighting erupted more than two weeks ago. 100,000 have gone to neighbouring countries. from vintage and sparkling cat costumes, fingerless gloves, and iconic chanel pieces, it must be the met gala 2023.

we've been talking a lot about artificial intelligence today because dr geoffrey hinton, the man widely seen as the �*godfather of artificial intelligence' has quit his job at google, warning of the dangers of ai. he's worried that al technology will flood the internet with misinformation. well, to look at some of the applications of ai in a bit more detail, courtney bembridge joins us from the newsroom. there are so many ways that al is set to change our lives. i wanted to have a look at some of the other applications. this piece in the guardian talking about noninvasive mind reading, turning our thoughts into text, it is designed to restore speech in those struggling to communicate after stroker motor neurone disease. sticking with

medicine, this example, talking about chat gpt�*s bedside manner, saying it was better than many doctors, more empathetic and give better advice, although i'm not sure many doctors would agree with that assessment. we got this from another tech website. a cancer detection study suggest that al can detect cancer in high—risk patients. these are all examples in the news recently about some good ways that al may help our daily lives. there ai may help our daily lives. there are also many dangers, and the risk of impersonation. this is the actor tom cruse, many of you will recognise him, but you may also think you recognise him in this clip. what's up, tiktok? are you guys cool if i play some sports? in fact, that is not tom cruse at

all. that is a deep fake, someone impersonating tom cruse using artificial intelligence, so a big can of worms is being opened with that. this is a recent headline talking about drake, the artist. he supposedly collaborated with another artist, song, but it was ai generated. so using this style of the vocals to make a fake song. that had to be ripped down from streaming websites because it was fake, unknown artist and record labels are going to have difficulty trying to address this kind of thing because the current copyright laws talk about using certain parts of the song, but not impersonating someone's style, that is not currently covered. ai is opening a big can of worms here in terms of what is considered copyrights.

mark brill is senior lecturer in future media at birmingham city university. good to see you. dr geoffrey hinton was so well respected among many people, academics as well. do you have some sympathy around the things he is saying and why he resigned? yes, and it is interesting because he has raised some important questions at this point of the development of ai. there are big ethical issues. he is not the first person to resign from an ai project because of these issues. he is the most high—profile. 50. because of these issues. he is the most high-profile.— because of these issues. he is the most high-profile. so, the spread of misinformation, _ most high-profile. so, the spread of misinformation, and _ most high-profile. so, the spread of misinformation, and the _ most high-profile. so, the spread of misinformation, and the difficulty i misinformation, and the difficulty knowing what is real and fake. the issue of v8s _ knowing what is real and fake. the issue of v8s is _ knowing what is real and fake. tue: issue of v8s is not knowing what is real and fake. tte: issue of v8s is not new. even back in the 19th century with the airbrushing of photographs are using

photoshop to change images, these are not new questions. the challenges we have is the speed and scale at which ai can do it, so it is very hard to keep up and understand what is real and what is fake. there is a whole range of ethical questions that need to be addressed around ai, notjust fakes. can you explain what is happening with chat gpt. some people are talking about it all the time, while other people would barely know what it was. what are the concerns around it? ., , ., it was. what are the concerns around it? ., . it was. what are the concerns around it? ., , ., ., . ., . ., it was. what are the concerns around it? ., . ., , it was. what are the concerns around it? ., , ., ., . ., . ., , ., it? has an academic, i have seen a lot of it, it — it? has an academic, i have seen a lot of it, it is _ it? has an academic, i have seen a lot of it, it is something _ it? has an academic, i have seen a lot of it, it is something the - lot of it, it is something the students and staff have been experimented with. it is thought to be the most rapidly adopted piece of software ever, so clearly caught the imagination of the public very quickly. it uses something called

large language models. it scours through massive datasets and the interesting part is unlike google, which gives you links to websites, it attempts to give you the best answer. it does this in a very naturalistic way, it speaks to you like a person, so we tend to connect with that and find the result is interesting and meaningful. does that also raise _ interesting and meaningful. does that also raise issues _ interesting and meaningful. does that also raise issues around the datasets it is tapping into, that there might be some bias within the dataset? ~ ., , ., , , ., dataset? without question. this is a ke oint. dataset? without question. this is a key point- it — dataset? without question. this is a key point. it wasn't _ dataset? without question. this is a key point. it wasn't something - dataset? without question. this is a key point. it wasn't something thatl key point. it wasn't something that came up in dr geoffrey hinton's resignation, but essentially ai learn within very large datasets, but within them there are historical biases. things like ethnicity and gender. they are only as good as the information they get. the algorithm itself, the software that is going

through that data, it is been described as an opinion included, so essentially the algorithm is what a group of people have decided is relative and important, and that brings in biases. can relative and important, and that brings in biases.— brings in biases. can i also get our brings in biases. can i also get your view. _ brings in biases. can i also get your view, and _ brings in biases. can i also get your view, and i _ brings in biases. can i also get your view, and i have - brings in biases. can i also get your view, and i have heard i brings in biases. can i also get. your view, and i have heard this debated for many years and it is in science fiction and fantasy as well, about the point at which it becomes intelligent in its own right. could that happen, when could that happen? there is a range of opinions and i will not take too much of a guess at the moment, but there are those who think it will happen very soon. dr geoffrey hinton is saying he thinks it will be upon us much sooner than he expected. there are those who think it is in the decades, which is probably where i said, and others who think it might never get to that

point. if you look at chat gpt, it appears german, but looking at the results it returns, but there are quite formulaic, a little bit mediocre if they are trying to write things like songs or student essays. so very quickly, if a student tries to hand in an essay from chat gpt, you know what to look for? yes. to hand in an essay from chat gpt, you know what to look for?- you know what to look for? yes, i 'ust had you know what to look for? yes, i just had one! _ you know what to look for? yes, i just had one! there _ you know what to look for? yes, i just had one! there are _ you know what to look for? yes, i | just had one! there are techniques that we use. you can also use ai just had one! there are techniques that we use. you can also use al to understand when it fake is used. thank you so much! here in the uk, a nurse accused of murdering seven babies and attempting to kill ten others has told jurors at manchester crown court she could not believe she was blamed for their deaths. taking the stand for the first time, lucy letby said her "whole world was stopped" when herjob

was taken from her. she denies attacking the new—borns in the neo—natal unit at the countess of chester hospital, between 2015 and 2016. live now to manchester crown court, and the bbc�*s rowan bridge. this has been an extremely long and detailed trial. we are now into the seventh month and today is the first time that lucy letby has given evidence itself. she appeared in court this morning and a long black dress and was questioned by her kc. he began by asking her a bit about her background, her upbringing and training to be a nurse, then he moved the period between 2015 and 2016, the period when she is accused of attacking these children. she was asked how many children she cared for in that period and she said probably hundreds. she was asked if she ever wanted to hurt a child, and she ever wanted to hurt a child, and she said that is completely against what being a nurses, only wanted to help and care for them. she then

talked about how she was removed from clinical duties over the allegations and the effect that it had on her. she said it had a devastating impact, that she had ended up on antidepressants and was unable sleep without medication. she said there were times she didn't want to live any more. she talked about two of the arrests, she was arrested three times over the allegations, the first time was at 6am in the morning where she was taken in pyjamas to a police station and as a result of those arrests she had been diagnosed with ptsd. lucy letby continues to give evidence this morning and the trial continues. she denies all 22 charges she faces.

20,000 russian troops have been killed in the ukraine since september. the us says it believes 20,000 russian soldiers have been killed in fighting here in ukraine since december and that half of this number is believed to be from the wagner mercenary group, which is the group that has been leading the russian efforts in the east of the country, especially around the city of bahmut. and many of these fighters are convicts who have been released from prison and have no military experience. now, for months, russia has been trying to seize barmouth. now, for months, russia has been trying to seize bahmut. and i think these numbers give us an indication that these efforts have come at a very high price. now, russian forces have made some progress there recently,

although ukrainian forces still control parts of it and perhaps this is the strategy here from the ukrainian forces to try to keep russian forces engaged in this war of attrition, to inflict heavy losses on the russian side. i think the numbers that came from the us also suggest that 80,000 russian soldiers have been wounded since december here in ukraine, but we haven't had any number for possible ukrainian casualties. now, this comes as the ukrainians are preparing for a counter—offensive to try to take back territory that's now under occupation. and yesterday, the ukrainian defense minister said that the preparations for this counter offensive are now reaching the finish line. and he said commanders would decide how, where and when that will happen. around the world and across the uk. this is bbc news. 1,400 competitors, 46 teams from 18

european countries, all coming she together in birmingham for the lgbtq+ union cup tournament. this is coincided with the 200th anniversary of rugby itself. so to bring this international tournament here to the west midlands where rugby was born is actually really special. the event was originally meant to have been hosted here by the birmingham bulls four years ago, but was postponed due to covid. 0rganisers say it was important to include a women's tournament, as well. people are so warm and welcoming and you feel like everyone is so united and it's hoped the event will help to break down barriers. you're live with bbc news.

sudan, absolutely terrifying and horrific for those trying to lead and those who are remaining. it couldn't have been a more picture —— different picture on the other side of the world last night. turning to one of the biggest nights in the fashion world, as the met gala in new york paid tribute to one of their own. this year�*s theme, �*karl lagerfeld: a line of beauty�*, honoured the late fashion icon, with attendees encouraged to dress in his honour. nada tawfiq has all the glitz and glamour from the red carpet. stars at the met gala are usually asked to interpret a theme. this year they were simply told to dress in honour of one man — the late fashion designer karl lagerfeld. many of his muses borrowed from chanel�*s archives. model naomi campbell wore a 2010 couture pink gown, and actor penelope cruz chose a vintage piece with a sequinned hood. well, this is actually a genuine karl piece from the museum from 1983.

so it�*s his actual dress. so we could hardly alter it. 0thers channelled lagerfeld�*s own personal style. the crisp white shirt and black blazer. and you have the sunglasses, the accessories, down to the shoes. yeah, well, i mean, it�*s a little... you know karl, he would always wear his gloves. we still need to have a little, you know, a little bling here. at first, it appeared this year would be more understated than most, focusing instead on the iconic looks that marked his career — including the chanel wedding dresses. but there were a few surprises. this is the one bit of theatre we�*ve had tonight — am homage to karl lagerfeld�*s much—beloved cat, choupette. it wasn�*t just jared leto who went full feline. it took nine hours for lil nas x to turn into a sparkly cat covered in pearls and crystals. and rapper doja cat transformed herself with a prosthetic nose. i wanted to have fun. this is my first gala, so i wanted to do it big.

it was hardly a first for rihanna — whose extravagant looks have become a staple of this event. she arrived fashionably late in a floral cape and a gown that highlighted her baby bump. another met gala in the box, and once again rihanna stole the show. nada tawfik, bbc news, at the met gala. it�*s almost as much about the internet�*s reaction as it is about the fashion. emer mccarthy breaks down the top five viral moments from this year�*s met. quite difficult to come up with only five. well, as we�*ve seen, felines are just as much in fashion as karl lagerfeld. i love this picture here of lizzo looking totally perplexed, probably unsure that it was jared leto in the choupette suit. doja cat and lil nas x, as we saw, also went with the feline theme,

another theme of this year�*s met gala, the hard launch. anna wintour, of course, the editor in chief of us vogue, making her first appearance on the red carpet with bill nighy, her new beau. of course, he�*s hot off the heels of his recent oscar nomination, keeping in line with announcements. serena williams took to instagram to announce that she�*s pregnant, debuting her beautiful new bump with her husband, alexis 0hanian, on the red carpet. she said, i was so excited when anna wintour invited the three of us to the met gala. supermodel karlie kloss also debuted her bump too. nicole kidman dug into the archives for her dress for this year�*s met ball. of course, she was part of one of the most expensive ads of all time, nearly 20 years ago, for chanel number 5

and this unbelievable gown, which was designed by karl lagerfeld himself, containing more than 350 feathers was reworn again last night. baz luhrmann was the director of that commercial and he appeared with his muse, nicole. now, finally, to end on a bit of a bitter note, the cockroach that was found on the steps of the met unfortunately passed away at the end of the night, with variety reporting, it�*s with deep sadness that we must report the cockroach was stepped on. and on that note, let�*s look forward to 2024. let�*s go to antalya. this is in the build—up to the election rally. he hasn�*t appeared yet, but a massive

crowd has shown up in antalya to welcome him. the election is less than two weeks away, deciding the fate of turkey�*s democracy. it has only been three months and a massive earthquake, it killed more than 50,000 people and displaced millions more. the backdrop, aside from the earthquake and the challenges it raised, is a serious economic crisis in turkey, and those that say there has been a democratic erosion under president art again. there is expected to be a record voter turnout this year, expecting it to be a very tight race, and the voters talking about things that concern them, the state of the economy and them, the state of the economy and the damage caused by the earthquake. this is a rally in antalya in turkey. we are waiting for the arrival of president art again.

hello. the rest of the day, i don�*t think there will be much change in our weather. think there will be much change in ourweather. for think there will be much change in our weather. for most of us it is a dry day, but a fair amount of cloud around. having said that, there are around. having said that, there are a couple of places where it has been really sunny and pleasant, particularly in the south—west of the country. we do have high pressure over us, but it doesn�*t always mean sunshine. you can see how extensive the cloud is across the country. we have had big breaks in devon, cornwall, parts of wales and in east anglia, but here, too, the clozapine development. quite a spread the temperatures, 11 degrees

in newcastle, but are hitting the high teens out in the west. also worthy of note are the pollen levels, they are high across the bulk of the country. tonight, the weather forecast is fairly straightforward. broadly speaking across the southern half of the uk, lengthy clear spells. further north there will be more cloudy. quite a contrast in the sky is clear and east anglia from only a couple of degrees, but in belfast, 9 degrees. tomorrow, the thickest of the cloud will be a northern england and scotland. at times there will be some rain, from glasgow up to the western isles. temperatures should be a bit higher in newcastle, up to 15. 17 in the south and cardiff. from thursday, changes are afoot. we will see weather fronts gradually moving in of the atlantic. that does

speu moving in of the atlantic. that does spell wet weather for south—western areas. quite an easterly breeze. for some of us that does mean it will be chilly close to the north sea coast, so on the aberdeenshire coast line may be not making double figures. 11 in newcastle. higher temperatures further south. in newcastle. higher temperatures furthersouth. into in newcastle. higher temperatures further south. into the weekend, the mixed bag continues. i think it will be in the form of showers rather than steady rain. wherever you see assemble with the sunny spells, that is likely to chop and change through the day, and day by day. goodbye.
