good evening. i'm rebecca wood and here's your latest sports news. chelsea's british record signing enzo fernandez made his debut, but it didn't help the side secure three points in the west london derby. it was another debutant who almost gave chelsea the lead. david fofana rounded fulham's bernd leno, only to see his effort blocked by tim ream. a "penny" for todd boehle�*s thoughts might not be the right expression after their expenditure in january, though. graham potter's side stay below fulham in the table but move up to ninth, nine points off the top four. but potter feels the club is on the right path for the long—term. i can see the profile, in terms of the age. they are ready to compete now, but i believe they will

get better and better, so that is exciting for us. and again, to work with the players that are already here and the players coming back from injury, we feel we have got a good group of players, a very strong group of players, absolutely. so now we need to gel and become a really good team, and that is where the work is. manchester united manager erik ten hag says he wants his side to focus on matters on the pitch, ahead of tomorrow's match with crystal palace at old trafford. it's after one of the club's players mason greenwood had all criminal charges against him dropped. greenwood denied the charges of attempted rape, assault and controlling and coercive behaviour. he'd been due to face trial in november this year and said he was "relieved". manchester united say they'll "conduct their own process" before deciding what to do next. this was ten hag's response when asked for a comment about greenwood at his press conference earlier. no, nothing. i can add nothing. i refer to the statement of the club.

have you ever spoken to mason, . or met mason, and will you be part of the process that - manchester united...? as i said, at this moment, i can't give comment about the process. and have you ever spoken to mason? i can't say anything about it, i refer to the statement of the club. at this moment, i can't add anything. uk athletics is calling for a change in legislation to ensure the women's category is lawfully reserved for competitors who are recorded female at birth. it comes after world athletics proposed allowing transgender women to compete in female international track and field events with suppressed testosterone levels. our sports correspondent alex capstick has more. this follows a review by uk athletics of the participation of transgender women in the female category. it began back in 2021 and they have concluded that it isn't fair for trans women to compete in female events. they say the suppression

of testosterone doesn't remove a physical advantage gained by athletes who have gone through male puberty. they are also unsure whether it's safe for transgender women to take testosterone su ppressa nts. so what they want to do instead is create an open category, which will include men and athletes of all sexes, while the female category will be protected and restricted to only athletes who were born female. but there is a problem looming, they say — the chairman of uk athletics says he fears they would lose any legal challenge, and they want to change the british equality laws because of the gender recognition act, which allows people with gender recognition certificates to be allowed to be treated as females for all purposes, and that includes sport.

now, some have said the 2010 equalities act addresses that issue and it does allows for the protection of the female category in sport, but clearly uk athletics are not convinced by that. in a statement, the lgbtq+ campaign group stonewall say... meanwhile, fair play for women say... ukraine's top female tennis player and olympic bronze medallist elina svitolina is calling for sanctions on russian and belarusian players to continue.

the ioc is under pressure from the un not to discriminate against athletes and allow them to compete under neutral flags, but svitolina doesn't agree. i don't think that the neutral flag is changing so much anything. for me, it's more about, we should sanction as much as possible the people from russia and belarus, because their government is doing severe things in ukraine. unfortunately, we cannot choose some who say, "we are against the war," and some are for the war, because they are wearing z on their chest. so, in this, unfortunately we cannot choose, but we have to do it. we have to sanction them all, because this is the only way that can stop the war.

former england cricketer matthew hoggard says the yorkshire historical racism investigation and disciplinary process has failed everyone involved, including azeem rafiq. hoggard, who's facing four charges from the england and wales cricket board, has withdrawn from the process. rafiq first made claims of racism at yorkshire in august 2020 and later called english cricket "institutionally racist". the public hearing was due to take place next month, with seven individuals charged. tim bresnan and john blain also pulled out of proceedings, following andrew gale's withdrawal injune. in a statement, the ecb says... the six nations begins on saturday,

and for england's new head coach, the calcutta cup match against scotland will be his first in charge. england are looking to beat scotland for the first time since 2020. there's a return to the side for 35—year—old prop dan cole, who could win his 96th cap more than three years after his last appearance. as you get older in your life and in your career, you realise you haven't got many games like this left, so to be able to play in front of 82,000 at twickenham, calcutta cup, first game of the tournament for us, you're certainly excited. there's a buzz. you can feel that anticipation in the air, especially when we run out. i'm looking forward to that buzz again. and finally tonight, is football doing enough to tackle global warming and really doing its bit to put the environment first? most people may say no. the carbon footprint of football is huge, and only last month you might remember nottingham forest were criticised for flying to blackpool for their fa cup match. that is by no means

the only example. well, tomorrow is the first ever green football weekend and will spotlight climate change at games across the country, with clubs, players and fans taking part. nesta mcgregor reports. port vale might play their actual football in england's third tier, but they are top—five in the uk when it comes to trying to save the planet. as part of green football weekend, players like funso 0jo and fans can collect points for the club by scoring green goals for things like ditching single—use plastics, swapping the bus for a bike, or beef for broccoli. the midfielder has completed more than 260 activities this season, which organisers say could equate to half a tonne�*s saving of carbon emissions. i go on walks, i see plastic, i pick it up. if i can bring a change to five young kids, it's going to make a change in the world. and there's hundreds, thousands of footballers, so if we all do our bit and get some more awareness and education out there, we can

actually do something. this weekend, teams across the footballing pyramids, including manchester united, liverpool and tottenham, are making the issue of climate change part of their match day agenda, as will championship leaders burnley. sunday league games are affected all the time by pitches being flooded, people get trains cancelled because of the heat. the players talk about what they do as individuals, or as the full team, it can only serve as a positive to make people think. football has come and continues to use its reach to affect social change, tackling racism, homophobia and now climate change, which could be its biggest challenge yet. football at the moment - is an unsustainable practice. looking at the fixture schedule would be a good start. - you know, we are seeing games every three days. | it's incredibly intensive and that| obviously means that clubs have to rely on more carbon intensive| forms of transport like air travel. turning down your heating and wearing more in the layer up

challenge is another way fans can get involved in the green football weekend. 0rganisers say we all have a part to play — a green goal might score points for your team, but it's a win for everyone. nesta mcgregor, bbc news. that is almost all of the sport for now. don't forget, you can keep up—to—date with all the six nations action and britain's battle to get to the final 16 of the davis cup over the weekend, but that is all from me. good night. this is bbc news. we'll have the headlines and all the main news stories for you at the top of the hour, straight after this programme.

over the last 20 or so years, we've seen how difficult the internet and the web has been to police. it's bigger than any one country, and you can base your business in any one of them, depending on whose laws you want to adhere to. and it's opened up more ways for us to cause each other harm. disinformation, bullying, fraud. you name it, and you can do it online. so when it comes to the next generation of the internet, often referred to as the metaverse, we're going to have the same problems. and even though the metaverse doesn't even exist yet, there are those who are already thinking about these problems and trying to pre—empt the troubles we may face. and marc cieslak�*s been finding out how the international police agency interpol has been training to fight

real crimes in virtual worlds. terrorism... ..organised crime... ..and, increasingly, cybercrime. interpol�*s role is to connect police forces across international borders to fight these threats. from its headquarters in the french city lyon, interpol fosters collaboration between law enforcement in 195 countries. while the people inside this building co—ordinate interpol�*s activities in the real world, the international law enforcement agency is about to expand into a newjurisdiction. the metaverse. the metaverse remains a conceptual notion. the next evolution of the internet, where users experience their online

while the idea of the metaverse isn't quite ready for prime time lives represented by 3d avatars. while the idea of the metaverse isn't quite ready for prime time yet, interpol is already experimenting with the tech. first, to provide remote online training as well as researching threats the metaverse could pose. it even has plans to use it as an investigatory tool. what can we consider a crime in the metaverse? so, in terms of criminality, i would say we can broadly define it in two categories. some which are existing threats in different media and some are threats which may be totally new to metaverse — for example, things like financial frauds, data theft. those kinds of things are already happening. then there are other crimes where we don't know whether it can still be called as a crime or not. for example, there have been reported cases of some harassment, sexual harassment. now, if you look at the definitions of these crimes in physical space and you try to apply it in the metaverse, there's a difficulty.

so those issues are yet to be resolved. jurgen stock is interpol�*s secretary general. he thinks law enforcement and governments will need a proactive approach to regulating any coming metaverse. criminals are exploiting any new technology that helps them in making simply money very quickly. naturally, sometimes lawmaker, police, our societies are running a little bit behind. we see that currently in the deal with social media, for instance. it is important, of course, whatever new technology is being developed, that we consider security by design. i think this will be a game—changer. consider ethical elements but also consider regulatory elements and consider how criminals can use it. the kinds of crime and harassment this tool has been designed to highlight for law enforcement are already occurring in forerunners to a proper metaverse experience. a worrying number of cases of harassment and abuse in social virtual reality spaces have come

under the spotlight in recent months. nina patel is the founder of a metaverse company. she's experienced sexual harassment in vr first—hand. right now, today is the opportunity to lay the foundations for laws that apply to both the physical and the virtual world, and what is illegal and unacceptable in our physical world should be reflected equally in the metaverse. my particular experience was around sexual harassment in a newly launched social virtual space in which three male avatars surrounded me and continued to sexually harass me, verbally harass me. and when we think about children entering these spaces and people who are vulnerable in our communities entering into these social virtual spaces for the first time, and this is an example of how we're supposed to behave in the metaverse? i shared my experience to highlight how much action needs to be taken to prevent this dysphoric future

that we kind of are all afraid of. regulation, privacy, safety — all big metaverse challenges. interpol�*s experiment could herald the start of a new type of online law enforcement. my dad died at 59 with an aneurysm, and my two aunties have died. and i really wanted to just get it out so that i could carry on and enjoy my life. maria is undergoing brain surgery at leeds general infirmary. i want to go back dancing, like i was dancing before. she's getting a procedure to control an aneurysm, which could lead to her having a stroke — the fourth biggest killer in the uk. dr patankar will place a springlike

mesh known as a flow—diverter stent into maria's brain — but it's a risky business. the stent is a foreign material, and if you don't get it right in a blood vessel, it will irritate the blood flow, and it will cause thrombus, and that can block the blood vessels, and then you can get a big stroke and possibly die. so, ensuring that perfect fit is vital. each individual has extremely unique configuration of blood vessels. some people even don't have certain blood vessels. this is how unique the configurations are. so it's like a retina in your eye or fingerprint. and that's why no two people are the same. so that brings the problem with what is the best device in all those different parts of the body? because once a device is in, you can't actually get it out. well, now there's an app for that — presize by oxford heartbeat automates the stent measuring process and suggests the best stent for the job. this is one of the very first surgeries to use this new software as part of the nhs trial.

maria is going to be patient numberfour. and i've been granted exclusive access to see how it goes. this one? yeah. 4cm. right, 0k. that's one of the biggest ones i've treated. wow. with almost 20 years' experience behind the knife, dr patankar is the chief investigator for the pilot. no one aneurysm is similar to another. they have different problems. the access will be a problem. they can have different comorbidities. some can be ruptured, some can be unruptured. some can be 4mm, some can be 4cm, you know. so you have to focus and tailor your treatment depending on the aneurysm. quarter of millimetres in the person's brain can make or break the procedure. for human minds, it's actually impossible to compute which one is best and what's going to happen if you put a particular one in those wiggly kind of structures, as you saw, those spaghetti kind of structures. there is, like, 102 different variations of diameters and lengths.

tells you automatically, it has reconstructed the data for you. it's telling me that the artery, the stent is going to be small. it takes away all my pain away of trying to think and measure. the computer automatically tells me, "just use this." perfect. nice, yes. it's perfect. yeah. up until now, stenting procedures have been around 75% successful, but this is a possible game changer. katerina says her solution is almost foolproof. this trial is first of its kind. we're building the software, so it's a software product, but it's considered to be a medical device. so it's treated as if we were developing implants, manufacturing implants. so, it has to be the same level of scrutiny and certification. but, with all new tech, there's room for improvement. it needs more stents on the shelf. people don't have to have one stent, like, today i used one, but using presize i could have used four or five different types. but what i did was ijust gave a bit of a kick to the stent.

that was pretty amazing to witness, and it makes me think that any sort of new technology that can help those guys do a betterjob, it's pretty worth it. time to go retro now. this is a digital camera. when did you get your first one of these? early 2000s? i only ever had one. i mean, they were a real breakthrough at the time, but, oddly, they only lasted a few years because smartphones have already taken over, haven't they? yeah, it also felt like such a palaver to get the photos off it — which it shouldn't have done. it should have been simple. it should have been, but it was new, it was weird, it was complicated. i mean, who on earth would want to go back to those days? tiktok — and 200 million views of #digitalcamera can't be wrong. shutter clicks i never thought in my 20s i'd be romanticising technology from when i was 13. i have probably 30—odd cameras. i mean, i've put some... i've got a small collection there that i have. - they're all shapes and sizes. so, yes, it's becoming a bit of a problem. -

that's the other thing with these is that they break. sometimes, if i like hit it against my palm, it'll start working again, which is such a foreign thing to me. like, you can'tjust like bang your phone against your hand and then, like, hope that it works again — but with these, you kind of can. my name's scott ewart. i live on the isle of arran- on the west coast of scotland. i'm 32 years old and i i take photographs with old digital cameras. i'd seen someone else doing it on tiktok, and i was like, - "why am i not doing this? "this looks brilliant! " i'm katie glasgow and i'm 25, so i'm like on the top end of gen 2. i live in brooklyn now. the cameras i have now are ones that my older sister took to prom or, like, my brother had in college or that, like, my young childhood memories were recorded on. with your phone, like, you can take video and pictures of literally everything. so, your library is huge, versus you kind of have to decide, "oh, this is a moment that i actually want to preserve,"

or, "this is something i want to remember." i got a few folk ask, "0h, - where do you edit these photos? "are they edited?" and i always say, - "these are never edited." i want to show exactly how they come out on every camera, - because it would completely defeat the purpose. - it looks like memories, like, i think because it's so blurry and it's imperfect, it looks more like how we remember things. oh, it's all right. tech moves fast. i know, but i talked about film cameras the way they're talking about digital cameras! at least they'll get old one day, i suppose. well, haven't all of us? i'm afraid that's all we've got time for. full—length version of the programme can be found on iplayer. thanks for watching. we'll see you soon. hello. it's been quite a cloudy day

for most of us today. but this weekend overall, it's actually not looking bad at all. saturday still a little overcast for most of us, but come sunday, i think the sun will be out, and it should feel quite pleasant. so here's the forecast, then — at the moment, this evening, mild air is still spreading across the uk, and will be in place across the country during the course of saturday. but after that, saturday night into sunday, a change in the wind direction, and we will see colder air establishing itself across the uk. now here's the cloud at the moment, or in the last few hours or so — you can see quite a uniform, thick sheet of cloud across the country, broken up here and there. and that's how it'll stay through the course of the evening and overnight. so just a few clear spells here and there, and actually the cloud will be thick enough across some western areas to produce a little bit of light rain or drizzle. no frost this coming night, temperatures will range from around five celsius in lerwick,

to about nine celsius in stornoway — and for most of us it'll be somewhere in between, so mild for the time of the year. here's saturday morning starts off pretty cloudy, but some glimmers of brightness already developing. notice that across northern ireland and scotland here, for a time, there will be some rain as this cold front moves in gradually from the northwest. temperatures will be around double figures, i think, right across the board. now, that rain won't last for very long — and in fact, as it makes itsjourney further south, it will mostly fizzle out by the time it reaches, say, the peak district, and also wales and the midlands. so the south of the country will not be getting rainfall tomorrow. now the big area of high pressure will stick around for a few days, it's also an intense area of high pressure — so strong, really anchoring itself across the uk, light winds. we're right in the centre of that high pressure, and you can see the winds blowing around it. so here in the centre, with the light winds and sunny skies, it will actually feel quite pleasant. even though the temperatures are going to be a little bit lower — i think we're talking about eight celsius for most of us — it should feel fairly pleasant.

now the high pressure isn't going away anywhere in a hurry — it does mean, though, that we could have some misty, foggy mornings into next week. and of course, with clear skies and light winds, that does mean a touch of frost first thing, as well, across many parts of the uk into next week.
