the firm that owned the titan submersible which imploded, killing five people on board, suspends its commercial operations. plenty of that in the half hour ahead. sport, and for a full round—up from the bbc sport centre, here's hugh. hello from the bbc sport centre. andy murray has time and time again been the subject of a late night finish at willden in front of the home crowd. it could be another one of those nice and let's go to wimbledon now. chetan, they still have not finished the first set and have not finished the first set and have been on the court for nearly an hour. what is the latest?—

hour. what is the latest? tension. you can feel _ hour. what is the latest? tension. you can feel the _ hour. what is the latest? tension. you can feel the anxiety _ hour. what is the latest? tension. you can feel the anxiety in - hour. what is the latest? tension. you can feel the anxiety in the - you can feel the anxiety in the air is hundreds watch on henman hill, many british fans tried to will andy murray over the line. this is going along in the first set as you say and we are exceedingly heading for a first set tie—break against the fifth seed, against a man, tsitsipas, who has not reached past the fourth round here but compared to any murray who is a two—time champion but is now 36 with a metal hip. not one the people we would expect to be a contender this week but any murray says he is feeling good and want to couple of challenger tournaments on grass coming into these sheep and ships and he believes he can beat tsitsipas who has had frailties in the past. this could be a really long one after that it would be classic andy murray, as you said, it if it is heading to a tie—break in the first set at the moment, 6—52

tsitsipas. the first set at the moment, 6-52 tsitsi as. ., . the first set at the moment, 6-52 tsitsias. ., ., ., , , tsitsipas. you have some of the best ofthe tsitsipas. you have some of the best of the timber— tsitsipas. you have some of the best of the timber ships _ tsitsipas. you have some of the best of the timber ships weather - tsitsipas. you have some of the best of the timber ships weather so - tsitsipas. you have some of the best of the timber ships weather so far i of the timber ships weather so far to do some catching up the tournament need is a else has been happening will stop absolutely. first of the go—round matches play today with the defending women's champion through, having a bit of a scare against elyse corneille. co—ordinate nursing injuries we were not sure if he would get a completed match with the champion it really tight and nervous but she did dig deep and get that when she needed in the end and straight sets. an important win as she tries to went back—to—back titles and also into the third round, a lien at smith allina, the highest ranked ukrainian player, who one in three sets it was emotional afterwards as you can understand, back from maternity leave as well a quarter finalist at the french open. to surprise results today with two former grass and champions out with sloane stephens

and ostapenko going out. but when for several other prominent players, ship of all of going through who will play liam broady, and the big surprise with casper root and francis dfo smiling and joyful and very much looking forward to playing his third round match. but for day to come on friday. novak djokovic, s, swiatek all coming in out and he mary and tsitsipas at the moment possibly heading into a tie—break in that first set. indicative of the match a file that has not yet reached the tie—break during our conversation. thank you very much indeed. two players appearing in this ashes series for the first time made the headlines on day one of the third test at headingley. mark wood came into the england side after injury and took five wickets as australia were bowled out for 263

in their first innings. had all—rounder mitchell marsh not been dropped on 12, the tourists' total would have looked a lot worse. but he went on to score a run a ball 118, then taking one of the three england wickets to fall. their score of 68—3 has them 195 runs behind. another exciting day of racing in stage 6 of the tour de france, with the yellowjersey changing hands for the second stage in a row. the leader at the start of the day, jai hindley, is down to third after a mountain stage in the pyrenees turned into a battle of the two race favourites. defending championjonas vingegaard is now in yellow, but he didn't win the stage, finishing behind two—time winner tadej pogacar, who moved up to second after riding away from vingegaard to leave the dane with a lead of 25 seconds. much more on the website including the latest on any murray but that is all the support for now. thank you very much indeed.

nearly three weeks after the mini—submersible titan imploded, killing all five people on board, the company that operated it, oceangate, has reportedly suspended all exploration and commercial operations. since 2009, oceangate has been taking tourists to the depths of the ocean for a close up look at shipwrecks and underwater canyons. last week, the debris that was recovered from an area close to the titanic, which was presumed to contain human remains, was returned to a us port and is now part of the ongoing investigation. our reporter sean dilley is in washington. just remind us of the timeline. there were safety concerns? there were a couple of employees in particular among those, one anonymous, the other one was some years ago, it's historical. the chief director of the company had taken legal action and that was dismissed in november 2018, but the late chief executive who was among the passengers who died had also

said people are remembered for the rules they break. very sad indeed. just to remind our audience of a little bit of the timeline here, friday the 16th is when the ship set off from st. john's harbour in newfoundland. carried on a ship carried the polar prints by at horizon maritime and sunday the 18th, it began its mission down into the atlantic ocean, 400 miles away from st. john's. nautical miles. that whole mission was slated to last for eight hours, a couple of hours down, for hours on the surface looking at the wreckage and then ascending back up. but after having began the descent at 8am eastern time, 9:45a:m., one hourand began the descent at 8am eastern time, 9:45 a:m., one hour and 45 time, 9:45a:m., one hourand 45 minutes later it time, 9:45 a:m., one hour and 45 minutes later it lost communication which it never re—established. it was not for some hours later that that vessel had been formally reported missing, spending on to monday the 19th. international search and rescue mission was

launched by the canadian and us coast guard working in partnership initially with private companies along with countries like britain, france throwing some resources. just 96 hours of oxygen on that submersible at the point that it dived, so you can imagine it was considered to be very urgent with many resources deployed. tuesday the 20th, a canadian p3 aircraft had given some hope to rescue us, could it be that there were people banging on board sending a signal? that was speculation at the time that they had been signalling for help but unfortunately it was on the 22nd, a thursday, the us coast guard with sadness announced that that rescue mission had ended. they said that all five souls they believe at that point had died as a result of a catastrophic implosion which was later confirmed. i catastrophic implosion which was later confirmed.— later confirmed. i suppose the investigation _ later confirmed. i suppose the investigation and _ later confirmed. i suppose the investigation and all _ later confirmed. i suppose the investigation and all the - later confirmed. i suppose the - investigation and all the questions that there are about corporate culpability and many would probably

think that the company was not tenable, so what does this mean then for the future of oceanic exploration because really they were the only company that was doing this? ., the only company that was doing this? . ., �* , , the only company that was doing this? . . �*, , this? yeah, i mean, it's very sad and this was— this? yeah, i mean, it's very sad and this was to _ this? yeah, i mean, it's very sad and this was to some _ this? yeah, i mean, it's very sad and this was to some extent - this? yeah, i mean, it's very sad and this was to some extent on | and this was to some extent on inevitable announcement. james cameron, the titanic director, among the speaking to bbc news and other networks later after us, he himself has been exploring for many years, so it's not new that there would be expiration. obviously stockton rush was very much the and of course he was very much the and of course he was one of the five pastors we must be respectful is saying he was seen is very much a maverick, a renegade chemist but he wanted to be an astronaut and a wanted soup explore the surface of mars but realise that would be possible without more of a commercial interest by government. so he pressed forward and was ignoring safety warnings by his own admission that you should not use carbon fibre to build such a submersible. that was something that

he dismissed and again i remind you what i said at the beginning of this chat actually is to quote him, people are numbered for the rules they break and in this case it's a very sad legacy for a man who died alongside four other passengers, each of them paid to a quarter of $1 million in admission.— each of them paid to a quarter of $1 million in admission. thank you very much. artificial intelligence — is it an existential threat? a technology that could one day gain autonomy and wipe us all out? or is that nonsense, a distraction, the sort of doom—mongering hype that might hold us back as others countries develop the ai tools of the future? sitting in the middle of that very active debate is demis hassabis. he is the chief executive of google's deepmind, and as such, he has control of one of the most powerful ai units in the world within his offices in kings cross, central london. in an interview with the times today, he says ai could lead to breakthroughs in all kinds of areas, the new fuels for space travel, drugs for incurable cancers, better energy storage, quicker and more effective ways of working.

so how do we harness the power that al offers without straying into the more dangerous areas we may not yet even perceive? sir nigel shadbolt, a researcher in al, professor at oxford university and executive chair of the open data institute. very welcome to the programme. do you worry that amid all this scaremongering that me and many others have reported on in recent months that we are losing sight of the very many benefits that are there? i the very many benefits that are there? ~ ., �* , ., the very many benefits that are there? ~ ., �*, ., , the very many benefits that are there? ~ . �*, ., , there? i think that's a very good oint. there? i think that's a very good point- look. _ there? i think that's a very good point. look, demis— there? i think that's a very good point. look, demis hassabis- there? i think that's a very good | point. look, demis hassabis has pointed out some of the areas where ai actually contribute any and will contribute hugely in the future. drug discovery, prediction of disease, is already performing at levels to analyse images from ct scans to x—rays. there is a whole range of ways in which ai, which is great at finding patterns, great at

producing outcomes, great at finding and applying the rules that might help us build better solutions, can operate to our benefit. a good example is climate change, another a potential threat. example is climate change, another a potentialthreat. it example is climate change, another a potential threat. it will be the ai driven models help us understand how the climate is changing what we can do to ameliorate those effects. they will be hugely consequential. and one could really reel off a whole range of area where the benefits really are there to see. they have been there for decades. we are seeing them more dramatically revealed with increases in computing power and advances in al. the revealed with increases in computing power and advances in al.— power and advances in al. the tony blair institute _ power and advances in al. the tony blair institute wrote _ power and advances in al. the tony blair institute wrote in _ power and advances in al. the tony blair institute wrote in a _ power and advances in al. the tony blair institute wrote in a report - blair institute wrote in a report last month of the uk's enterprise in this field is overly dependent on one single us owned and funded entity, talking about google deepmind, which demis hassabis runs. there is quite clearly an incredible talent base here in the uk. how do we harness that? how do we ensure that other companies from other parts of the world come here to use that talent base? i

parts of the world come here to use that talent base?— that talent base? i think it is a broader ecosystem. _ that talent base? i think it is a broader ecosystem. i - that talent base? i think it is a broader ecosystem. i think - that talent base? i think it is a | broader ecosystem. i think the tradition of ai research in the uk goes back decades. all the way back you can argue to the founding, little of the founding father of computing which is alan turing, writing papers on the potential for machine intelligence back in the 19505. machine intelligence back in the 1950s. you can see work in the 60s, 70s, 80s, 90s, into the 2000 square uk researchers from our universities and research labs and industrial companies have developed ai, much of which is right there, right now unremarked on on our systems mobile phones, and logistics supply software that runs our retail, just—in—time systems, planning systems. there is many fruits of ai already there and i think the uk and is well positioned with its brilliant higher education system, with its pool of talent coming through. one of the challenges is to retain some of those companies, some of those start ups we are seeing, some of those great new ideas within

the uk, and i think that will be a challenge going forward to how we capitalise and maintain. but also working in the wider international context is a win also because we get access to a wider talent pool to think about, if not all about sovereign power, it's also about working collaboratively to together. nonetheless there are these risks and concerns and demis hassabis spokein and concerns and demis hassabis spoke in this article today about the need for oversight and he has joined the call for two international bodies to research and regulate ai. so we talked about something many akin to cern with a note from particle physics and collaborate on research and also akin to the iaea the nuclear washed all that sits there to control the rest. do you see two bodies working together to control the risk and advance the research? i together to control the risk and advance the research?- together to control the risk and advance the research? i think as we

look at al, — advance the research? i think as we look at al, it _ advance the research? i think as we look at al, it is _ advance the research? i think as we look at al, it is what _ advance the research? i think as we look at al, it is what we _ advance the research? i think as we look at al, it is what we call - advance the research? i think as we look at al, it is what we call a - look at al, it is what we call a general purpose technology that can be applied to many different problems in different sectors. so it's difficult to regulate it in specific particular areas, all the people are saying about how our regulator skin manage the risk. and i think regulators across all countries will important looking at a risk—based approach, looking at principles that can drive safe deployment. the idea of these larger multilateral, international institutions, so again using models from her we thought about another great site breakthrough in physics and nuclear energy. it was used for good and ill and working out how you can manage proliferation, how we can limit and how we can put in some sense guardrails around appropriate deployment. that is an area where we want to try if i international agreements. what the exact will that will be, i think that's just what countries are nothing about how they can find common ground on developing

principles and organisations to support that. and i think it would be really important that countries start to imagine how they can find not only the perfect enemy of the good but five principles they can agree on where essentially we can get wider consensus on what we do and don't do in this technology. fascinating. the queue for being with us this evening. mark zuckerberg says more than 30 million people had signed today to its long—awaited competitor to twitter. the app, called threads, is a very similar "text—based conversation app" on which users can post messages up to 500 characters long and include links, photos and videos. sounds familiar? and as with twitter, the posts can be replied to, liked or shared by others. the app is directly linked to instagram, meta's popular photo—sharing platform which has more than 2 billion users, and is being rolled out in more than 100 countries for ios and android. bruce daisley is author

stories was inspired by snapchat stories. reels was inspired by tick—tock and i suspect with things we might be the best inventors in town but when it comes to execution, we are pretty much the best around. there are lots of newcomers in this field. the difference here though of course is that instagram has 2 billion users already, they already have regulations and controls across instagram. so in scale and in tight, this is an entirely different proposition. this is an entirely different proposition-— this is an entirely different proposition. this is an entirely different --roosition. , . ., ~' proposition. very much so. i worked for a lona proposition. very much so. i worked for a long time _ proposition. very much so. i worked for a long time at _ proposition. very much so. i worked for a long time at twitter _ proposition. very much so. i worked for a long time at twitter and - proposition. very much so. i worked for a long time at twitter and one i for a long time at twitter and one of the challenges we had was persuading new people to open accounts and then showing them that there was a been good for them. now with instagram having to begin users, to try and encourage to percent of those people to slide across and have a look gives him a business and if you can persuade 20 or 30%, that arguably he's bigger than twitter. so while it might seem like a gamble and some people have

said that maybe it's an attempt to have a success after the relative failure of the meta verse, i suspect from the perspective they think this is what we do best. this decentralisation - is what we do best. this decentralisation within i is what we do best. this decentralisation within social media and particularly around text conversational apps, how do you think that's going to change the social media landscape?- think that's going to change the social media landscape? that's one ofthe social media landscape? that's one of the critical _ social media landscape? that's one of the critical elements _ social media landscape? that's one of the critical elements of - social media landscape? that's one of the critical elements of this. - social media landscape? that's one of the critical elements of this. he | of the critical elements of this. he has built it in conjunction with a mastodon platforms people can use it and one of the things that's been said today it is that people will be able to bring the account and follows other platforms if they so choose. i think the critical thing is actually a consideration about do we want one of our social apps to be over the same companies? and i think that's a conversation that is just starting to be had in the us. the ftc is looking at that. raising questions about competition. i think that's more i brought position. if

as those on mortgages. the bosses of lloyds, hsbc, natwest and barclays have denied accusations from mps that they've been profiteering. you're live with bbc news. there's growing tension in tunisia after a series of attacks on migrants from sub—saharan countries. this in retaliation for the killing of a local man. the issue seems to be centred on the coastal city of sfax used by many migrants as a staging post on what they hope will be a journey to europe. our north africa correspondent bassam bounenni is there and sent this update. dozens of african sub—saharan migrants are gathering here in sfax's city centre after a tense day in the to coastal city. they are looking for a way out.

some of them rushed into railway stations while others left on feet. protests erupted on monday after a tunisian was fatally stabbed by a migrant. the demonstrations turned violent, with migrants slaughtered and kicked out of their homes. translation: i woke up at 5am in the morning to go to work. i and i came across to a roundabout, and i wanted to cross the street. and these two young men came in and started trying to jostle me with their motorbikes, so i stopped. then they started to hurl insults at me, but i didn't say anything. and then ijust carried on. underlying social welfare in sfax is often linked to african sub—saharan migration. the local labour union accused the tunisian government of seeking to settle them in order to satisfy

italy and european union. but the president reiterated his rejection of any settlement plan, adding that his country will not be the guard of the eu's borders. local ngos, including the forum for economic and social rights and thejournalists union, condemned what they described as human rights violations and demanded any illegal referment to be stopped. there's fresh hope for the world's largest gannet colony on bass rock, a volcanic outcrop off the east coast of scotland. thousands of birds died last year when avian flu struck in the middle of the breeding season. our climate editor justin rowlatt reports. david attenborough: bass rock in scotland's firth of forth - is the largest gannet colony in the world. david attenborough's team visited bass rock three years ago.

at the height of summer, the whole of bass rock is jam—packed. but this time last year, right in the middle of the breeding season, bird flu struck. gannets, including chicks, died in their thousands. this was the population in 2020, an estimated 150,000 birds. this is 2022. a year on, and we are headed back to bass rock with a team of scientists from edinburgh university who are doing the first population survey of the gannets this year. there have been huge changes. this area was completely covered with birds. gannets everywhere. not breeding, but it was just full with life. maggie sheddan has been coming here virtually every week for more than 20 years. slowly, in the space of three weeks,

i've seen this colonyjust empty. it was heartbreaking to watch that, this magnificent bird that's so strong, just have no power at all. so it's going to start from the far corner. | the scientists send up a drone to take pictures. they'll use artificial intelligence to count the birds. because obviously humans are far more prone to error, so you can get tired, you can just get bored of counting the birds, which means you get less accurate as time goes on. a computer doesn't get bored, it doesn't get hired. but even without ai, you can see a lot of birds have come back. some have survived the flu. just look how it can change their eyes. and there are chicks, lots of them. maggie is delighted. this is magnificent, what we're seeing here. what we are seeing now, there's established breeders that have survived. there's a lot more than i think we hoped for. but lots of the birds haven't built nests. gannets pairfor life.

these birds are waiting for their partners to come back. but it's late in the season. maggie fears most are probably dead. it'll be a couple of months before the scientists publish theirfindings. the colony has taken a big hit, but the good news is the gannets of bass rock will survive. justin rowlatt, bbc news, the firth of forth. we will be right back, the panel was coming up. hello there. thursday was a better day for wimbledon and the beginning and play at headingley. two pictures at 23 degrees but friday tapping into he and he meant it with the returns may will peak is high as 29,84 fahrenheit. cloud and ran around and you can see quite clearly where i'm talking about on the satellite picture. this is a frontal system

bringing wet weather, fairly it shall write first thing friday morning across scotland and northern ireland. slowly brightening up into the after they met with that southerly wind direction dragging in that warm, humid air as we go through the day with clear skies across england and way and temperatures responding with highs of 29 celsius in one or two areas for the middle of the afternoon. that means for the tenants at wimbledon we could see temperatures as high as 27. has the potential to be the best or hottest day of this season's championship. a similar story as well for the men's ashes with thunderstorms perhaps threatening as we go through the weekend. into friday evening, relatively quiet. during the early hours of saturday, a front pushing it from the southwest with temperatures not falling very far. going to be a humid night and uncomfortable for getting a good night's sleep particularly in the southeast with it which is only as low as 18 or 19. when that front

continuing to move from the southwest and bumping into that humid air, that has potential to spark off some sharp downpours. they will drift their way steadily north and east of saturday will not be a wash—out by any means but if you do have outdoor plants, worth bearing in mind there could be some interruptions with some sharp shower. top temperatures is a go through so i still on the warm side at 20 or 24 and maybe 27 across parts of east anglia and the southeast. need to keep a close eye on sunday with the risk of some really sharp downpours moving up from france, butjust where they will appear is still subject to question to keep abreast of the forecast for the zeta half of the weekend. just to summarise the income of the weekend starts off on a human know and there will be some decent sunny spells around from time to time but also the risk of some sharp downpours. take care.

hello, i'm christian fraser. this is the context.
