the health ministry in gaza says israeli forces detained and interrogated around 100 medical staff from a hospital in the north of the territory after they forcibly evacuated the patients. the world health organization says it's the last major hospital in northern gaza now out of service. thick fog continues to cause delays and cancellations at some of the uk's busiest international airports. forecasters say the fog is likely to linger. and — these jeans were not made for chess — in fact it led to the resignation of the world's top grandmaster, magnus carlsen, who was defending his titles at two championships in new york. more than 1,000 critically endangered snails — some of which were bred in captivity here in the uk — have been released onto a remote portuguese island. the desertas island land snails were believed to be extinct

until an expedition team discovered a tiny native population, and set about growing their numbers. 0ur science correspondent victoria gill has more. this is a story with some very tiny main characters. these are desertas island land snails. they were rescued from the brink of extinction and brought here to chester zoo, where they've been living and breeding inside this converted shipping container. these were snails that were at risk of extinction or thought to be actually extinct in the wild, so we were lucky enough to have them brought to us. and this is where we've managed to breed up from very low numbers to what we have here today, which is almost like 1,400 snails ready for release. there are two snail species that the team are bringing back to their wild island home off the coast of portugal. discula snails and the even smaller geomitra. they're prepared for their journey with a little scientific makeover. we have uv markers and literallyjust a metallic pen.

why do they need to be marked? basically, so there are some individuals left in the wild, and we just want to be able to distinguish the ones that we've bred and released so that we can track them and track their progress. this is a discula snail. you can just see the shell is now marked with that green mark, and there's a uv mark in the middle. they are ready to go. the desertas islands, close to madeira in portugal, are their destination and their natural home. the largest of the islands where the last snails were found has had its habitat decimated, eaten away by goats, rats and mice that were brought here by people. so the team has transported the snails to the protected neighbouring island of bugio. it's meant a long and precarious journey. after waiting for the ideal cooler evening conditions... you're quite active!

..it�*s finally time to set the snails free. we're going to release them really close under the rocks, which will be the perfect place for the new life. where they have protections, humidity and a lot of food. this is a small but significant part of a mission to restore the natural habitats and wildlife on these mountainous atlantic islands. if it goes well, more snails will be brought here next year, each bringing a small splash of colour back to their habitat. victoria gill, bbc news. now on bbc news, tecthlore: beyond the games. in tecthlore, we go in search of the most exciting innovations around the world. and this summer, for the paris 0lympics, i tracked down the ground—breaking technology pioneered behind the scenes. it's been an amazing event, and now i'm looking at the tech

living on beyond the games. the sustainable innovations fit for the future... ..more precise tracking than ever before... the first i've done for television. ..game—changing new broadcast experiences... that's the magic of volumetric broadcasting. ..and a lasting legacy celebrating accessibility for all. join me for tecthlore paris — beyond the games. in 2024, all eyes were on paris. cheering the fans, the organisers and, above all, the athletes combined to pull off an amazing show — helped along the way by transformative technologies. paris 2024 was the largest spectacle ever to take place on french soil. in technology terms, its size means it's a unique test—bed. innovations developed

in broadcasting, staging and sport all live on well beyond the games. one of the most exciting new venues of the paris 0lympics speaks to themes the whole world is grappling with — technology and sustainability. this wave—shaped building is a brand—new aquatic centre. inspired by nature, it's sustainably designed made from a timber frame, all of its building materials are bio—based and its 5,000 square metre roof is covered in solar panels, making it completely self—sufficient. wow. it's an incredible space.

one of the ingenious elements of the design is that it's modular, and it can go from its current 5,000 capacity down by half to around 2,500. but innovation does notjust exist in the real world. in the virtual world, a perfect replica of the aquatic centre was crafted, every aspect of it mapped in a real time computer model. a complete digital twin. a digital twin is a representation of a venue in 3d, like a video game. so that helps them to plan in advance, to anticipate, to see how they can plan their operations in the most efficient way. for broadcasters of the future, digital twins bring an opportunity to try out different camera positions remotely. and for athletes like gold medal—winning british sport climber toby roberts,

the tech has been a game—changer. when i first opened the software, i was more just... i was sort of blown away. i wasjust so, like... suddenly i'm in the venue, i'm in le bourget in the olympics. it's really helped me create a mental picture of what it's going to be like competing. just as technology rose to the challenge, helping paris stage a spectacular show, each olympics delivers a step change in the measurement and refereeing of sport. paris 2024 was truly the games when ai arrived, and to see how it will affect sport both now and in the future, i headed to switzerland, to the official olympic timekeeping lab. oh, i assume that's the right time. omega has been the official olympic timekeeper since 1932, pioneering new technologies throughout the decades. all right.

i've got my blades on. i'm on the start line. i'm ready to go. on your marks, set... bang 3.51. i'm not sure usain bolt�*s got much to worry about. new for paris, this smart camera rig is capable of capturing 40,000 pictures per second over the finish line. so, this is my photo finish. it is, and it's looking actually very professional. you know, in athletics, the frontest part of the torso counts. so, you're leaning forwards here... i dipped for the line, i dipped for the line. and actually, another interesting thing is that you stepped on the line while you were crossing it, which is making one of your blades extremely long on the picture. so, it's multiple pictures that you see here aligned through time. i never thought i'd see myself on a photo finish, and judging by that look on my face, i'm not sure i ever want to again. for the future of sport,

this imagery gives judges the position info needed to make even the closest of calls. here you go, paul. thank you. my pb immortalised forever. another visual capture method debuted at paris uses multiple cameras to track athletes from all sides... great, and i can see myself up on the screen up there doing my little dance. ..and, for the first time, ai computer vision was used for body tracking across beach volleyball, gymnastics, tennis, swimming and diving. and diving in particular is extremely interesting because the jump in fact lasts only 1.5 seconds. almost impossible to see differences in athletes�* performances with your naked eye. romania's nadia comaneci is a five—time olympic gold medallist and the first gymnast ever to receive a perfect 10 in 1976. she supports this approach to ai assistance. helping the judging angles, landings, positions — the basic things will be more faster, actually.

there are a lot of aspects of ai that will help the athletes. it also makes the fans understand why the judges are doing this, why the deduction was like that. they will explain immediately every question you have. over the course of the games, i've been lucky enough to gain exclusive access to olympic and paralympic athletes using technology to boost their performance. these incredible innovations though, will, of course, have a much broader impact. as usa football captain, lindsey horan piloted her team all the way to gold, beating brazil in the final. she showed us the secret of her success — incredible muscle mapping tech she's been using to take her performance to a whole new level. you can always improve little things. maybe this will be that much better, or i can be a little

bit faster on the field, strengthening one muscle that i didn't know i needed to strengthen. just shows you a better idea of how your muscles are working. that i worked really hard on and now on my left hamstring isn't as great! i tried the tech myself, which all starts with a regular mri scan. well, it's certainly a novel experience. something... a first i've done for television. a couple of days later, i went to london's queen elizabeth olympic park to see my scans transformed. we get the 2d, grainy, black—and—white images that you see from an mri that none of us know what to do with. we have an ai that actually automatically segments the muscles and the musculoskeletal system, and then we create a true to life form of the human body of who we capture. the body can be compared against itself for symmetry, or against the wider population. now, i noticed when i looked

through the results the words "fat infiltration" quite a lot. that sounds pretty bad. what does that mean?! you actually are on the lower end of the spectrum of having an amount of fat inside of each individual muscle. such precision health particularly benefits women, who've been historically overlooked in sports science. there is so much given into the men's side of the game in terms of, you know, injuries, in terms of statistics. now it's starting to progress a lot in the women's game, and they're also seeing women and men differently. around the world, different teams are advancing different technologies. south korea's archers won every gold up for grabs. behind them, a team of hyundai motor group engineers building advanced robotics and ai training. translation: the equipment

fires each arrow with the same angle and the same intensity. only arrows hitting virtually the same spot are selected for competition, ensuring maximum consistency. translation: as you can see, the second arrow struck - slightly to the left and below. and for improved feedback in training, a camera tracks the athlete's posture when shooting — again to ensure consistency, this time in body position. translation: the purpose| of this equipment is to allow athletes to save their poses more simply, offering immediate review. i can't wait to see what archery innovation the engineers will bring to the next olympics. the olympic games are always a driverfor innovation in broadcast technology, and paris was one of the biggest ever examples of this. i visited the heart of production, the international broadcast centre, which sent coverage to more than 200

countries and regions around the world. during the paris olympics, it was the most content dense place on earth. traditionally, olympic broadcasting has been done via satellite. footage is sent up, back down, and then all around the world. now, this can all happen on the cloud. instead of shipping equipment, tens — or hundreds, sometimes — of racks of broadcast systems and appliances all over the world, you can just have more or less equivalent type of infrastructure spinning up using cloud facilities, do the operation that we need and then spinning them down after the end of the games, with no real physical impact. epic on—site servers sent games content to huge data centres around the world. but this is really where the heart beats. getting all this content from the venues, you know, managing this, processing this and sending it to the world.

11,000 hours of paris content came through here — enough for a whole year of constant coverage. absolutely phenomenal, and you need a good electrician on your staff with all of this cabling. the cloud team at olympic tech partner alibaba has been working on projects that transform the way broadcasters, visitors and viewers experience the action. the cloud and the altogether, all of this technology can support so many things like that automatically. the clever photo finish cameras, the smart energy for venues and bao, a virtual helper for fans, all ran on the cloud. is it the bao like the... like the bao buns? yeah, yeah! who won the men's 100m at london 2012? ..2012 london olympics was won by usain bolt ofjamaica. - its large language model understands even complex questions.

if i was to race usain bolt, but he could only hop, would i win? athletic ability and distance will still play a role in - determining the outcome of it. well, i don't have any athletic ability, so i think he'd still beat me. the cloud combined with al is going to be key to the future of broadcasting. here, olympic partner intel is using its al to generate tv highlights live — an incredible thing to see. i can see things are popping up in real time, so this is actually generating highlights right now. that's right. it takes an input of the live sports competition and the algorithm detects actions in the place. the algorithm watches the action live and tags it for important events for that sport. video from venue cameras, audio from the event and data like scores, stats and timings all go into deciding what is important. broadcasters, and ultimately viewers, can receive highly tailored highlights packages based on these tags, as the ai spits out custom videos.

the sports that don't get a lot of love get coverage now, because we don't have to dedicate a person to sit there and tag this all the time. the way video content is captured and shared is also being transformed thanks to 5g. in paris, intel placed 5g antennae all along the famous river seine, enabling unprecedented broadcast of events on the water. when you think about cameras and wires, you needed a wired camera if you wanted live broadcast. yeah. now we've got points, bridges, that we can put antennas, we're enabling connectivity for the entirety of the river, which makes the broadcasters able to capture content, upload it and get it to a live audience at home. it's a method that's forever changed the future of water sports coverage, with antennae on boats massively enhancing the experience for tv viewers. what we now can see... you are seeing what the

skipper's doing in a way that you've never been able to see before. real live shots from the boat at the sea, during the sailing. amazing. it will be fascinating to watch all these broadcast innovations as they advance in the years to come. with millions watching, there's no doubt the paris games inspired the world. and though the olympics has traditionally got more attention, the paralympics drives forward life—changing innovations for disabled people in and outside of sport. with such a diverse group of athletes and attendees with a wide range of needs, it's the ideal opportunity to test drive the latest tech, notjust for future games, but for the wider world in general. some 350,000 disabled fans visited paris — a city changed for the better, with improved venue access and transport systems. innovative electric vehicles were brought to the fore by olympic partner toyota, including electric aids for wheelchair using

athletes and staff. how to move it — brake, one hand... yeah. ..acceleration, one hand. ooh! if you just move down, you go. great. and i'm just setting that to top speed, just so you know. they laugh and i'm off — at a safe limit of 6kmph. this is amazing! wind in my hair! what hair i've got. the easiest 400m i've ever done. crucially, this doesn't require thumb or twisting motions to control. georgios kapellakis, the president of the greek paralympic committee, used one to carry the olympic torch, and paralympic athletes used these at the opening and closing ceremonies. really easy to drive. i can even do it with one hand — or one arm, in my case.

inside the stadiums, new technologies are transforming the way blind fans enjoy the action, with immersive tools rolled out for the most inclusive sports experiences yet. so, this device helps people inside feel the action. can you tell me a little bit about how it works? yeah. so, it's for blind and visually impaired people, so, they can touch these tablets, and we have here a magnet, and the magnet moves to show the position of the ball. so, theyjust have to touch it and they will feel the action of the game. oh, cool. it's moving! the tablet also vibrates at key moments... ooh, ooh! is that a try? ..like a try scored in the rugby. it is. there we go. it was a try! the tablet can be adapted for all kinds of sports, and i'm hoping it will become a staple forfuture sports events worldwide. the real beauty of this is that there's no audio delay, and so blind people can feel what's happening and really be immersed in the atmosphere.

for blind paralympians like team usa long jumper lex gillette, the technology developed at the games brings promise of a more accessible future. gillette has won five silver medals over his career, an inspiring feat. he showed me how a new app helped him navigate the team training camp. automation: go straight. ah, there we go. right, so we're off and moving. turn right and continue seven metres. - turn left and continue four metres. - turn right... yeah, all right. got us around the corner. to map each space, a 360 degree point cloud is painstakingly collected by hand. ai and computer vision then takes this 3d data and crafts the step by step guide. continue eight metres. slight left and - continue four metres. slight left...

go straight. arrived, running track. there you go. so that was pretty good — that got us to the track pretty unscathed, i would say. yeah. how was that to use, for you? yeah — definitely... it was really interesting trying to figure out what it means to rotate left, or turn left. so, i think, after a while, you use the solution a few times, you get used to it and you learn that path pretty easily. i canjump six metres, so i kind of know how far that is. yeah. though this is the only paris site map so far, the team's ambitions are huge for the future. this year's deployment has been focused on the athletes, primarily, and specifically at the performance centres and the training grounds. and in coming games, we're hoping to expand that to visitors and staff and people attending the games, as well. perhaps most inspiring are the paralympians using technology to push the boundaries of the human body and even make

it onto the podium. i met team usa's brian siemann, a three—time paralympian who medalled in both the 400 and 800 metre sprints in paris. ahead of the success, the us track and field star had been wearing a unique high—tech sleeve from a start—up called nextiles. you just slide it up, make sure that it is lined up with your elbow. it is the only sleeve in the world that has the technology that wheelchair racers can currently use to actually collect real time cadence data. this first—of—a—kind data comes from biometric threads concealed in the elbow, combined with data from an accelerometer. it's measuring how quickly and how far those fabrics are actually going back and forth, and then giving you real time data so that you can actually adjust your training session. brian uses an aluminium racing chair with carbon fibre features, and his phone attached. you can sort of make adaptions in real time

from what you're seeing. yes. that's really cool. well, i'm going to let you crack on. all right. wow. brian's personal best is 400m in 47.84 seconds. holy moley, he's halfway round already. wow, amazing! how easy is it to find technology like this that's tailored specifically towards disability sport? it's so hard to get companies to invest in athletes with disabilities and make sure that their tech works for us. to have something like this to help improve my performance is really special, but i think, in the big picture as well, it's advancing accessibility for everyone. i know the challenges of navigating life with a disability, so seeing technology developed for athletes and everyday people alike is powerful.

even more important is that this lives on as part of a long—lasting legacy. push the sport and the para sport directly to the younger and the person with disability, and in more than that, for me, the behaviour is very important. if we can show, if every public can look the paralympic record, i'm sure that they change their view around the disability. when i began exploring olympic tech for paris, i had no idea of the range and breadth of innovation i would find, and the passionate people behind it all driving it forward. i cannot wait to see the impact it has, not just in future games, but much further beyond.

hello there, some higher parts of england and wales have again been sticking out above this misty low cloud today. it's quite gloomy and murky and a little damp in other parts of england and wales. the fog, though, probably not quite as extensive as it has been. and through the rest of the weekend, the breeze picks up a little, that mist and patchy fog will be lifting, promising some brighter skies more widely tomorrow, although there will be some rain still in scotland. the mist and fog is closer to this area of low pressure which is affecting other parts of europe as well, that weather front weakening as it moves south, and another band of rain heading into northern scotland by the end of the day. but temperatures in scotland and northern ireland in double figures. where it's grey and gloomy through the midlands, south—east england, it's going to be a chilly 5 or 6 degrees here, again. and still some extensive low cloud, some patches of mist

and fog into the night, tending to lift from the north, as the breeze picks up, and we see some rain arriving across more of northern scotland, particularly towards the highlands. where we do see a few breaks in the cloud further south, temperatures could get close to freezing once again. we may still have some mist and patchy fog to start with in southern parts of england and wales on sunday. that should tend to lift, skies brightening, there may even be a bit of sunshine across more areas. further north, though, with those stronger winds in scotland we are going to find some further rain across the northern half of the country. but temperatures should be higher in england and wales with the promise of a little sunshine, temperatures reaching 9 or 10 degrees. we are going to find that rain, though, continuing in scotland and every now and again an area of low pressure develops on that, intensifying the rain. and it's bumping into colder air in the far north of the country, so we could well find some snow in parts of scotland. it's rain for the most part, but some of that rain will be affecting northern england and northern ireland on monday.

further south, the breeze continues to pick up a little, and bring in a few holes in the cloud but lifting temperatures into 10 or 11 degrees. but it is colder in scotland, and this is where we could have some disruptive weather at the end of the year. monday into tuesday, from the central belt northwards, mainly some heavy rain, but there could be some snow for a while. as that melts it brings the risk of flooding and some travel disruption as well. but things could get even worse for new year's day because the next area of low pressure is going to be deeper, it'll bring stronger winds, more widely, some heavy rain and some heavier snow in scotland.

live from london. this is bbc news vladimir putin has apologised to azerbaijan's president over the passenger plane crash in kazakhstan. he called it a tragic incident over russian airspace, but didn't take responsibility. the health ministry in gaza

says israeli forces detained and interrogated around 100 medical staff from a hospital in northern gaza after they forcibly evacuated patients. thick fog continues to cause delays and cancellations at some of the uk's busiest international airports. and — these jeans were not made for chess — in fact it led to the resignation of the world's top grandmaster. russia's president putin has apologised to the leader of azerbaijan over what he called the "tragic incident" involving a passenger plane — which crashed killing 38 people on wednesday. he acknowledged that the russia's air defences were "active" at the time does not say that russia was responsible. there's speculation that the azerbaijan airlines plane came underfire from russian air defence
