donald trump cannot run for president next year in the state. officials say they've banned him because he incited his supporters to storm the capitol building in january 2021. israel expands its ground offensive into palestinian refugee camps in central gaza, forcing thousands to flee. it comes as a hamas delegation heads to cairo to give its response to an egyptian ceasefire plan. now on bbc news...click. this week, nick's getting into his trunks to find out what a phone can do for a forest. now i've just completed another survey injust under a minute.

we'll find out what lara's thinking as she immerses herself in culture. i know what i'm looking at now, but how do i feel? and less than two years after ai took up art, is it ready for hollywood? spencer's getting his big trailer voice ready. the ai will listen to the audio... deep trailer voice: ..and generate me a new one. jazz music plays. this is the tinpot jazz orchestra. it lasts less than a minute, but it is a charming, glitchy, cartoon—like production created using generative ai video tools. now, this means that the characters weren't designed by illustrators and animators. instead, they were described

in english to an ai, which then created them itself. the film was made by william bartlett, who's a creative director from visual effects house framestore, and who, like a lot of generative ai creators at the moment, put it together in his spare time. it started off life as a test. and i wanted to do a test that was more elaborate than just a couple of shots. i wanted to try and string together something which had a bit of narrative to try and drive the kind of ambition of the shots. will actually had to use different generative ai tools for different parts of the process. first, he asked midjourney to come up with some still images of the kind of characters that he wanted. and so i might describe a sort of vintage tin robot playing a trumpet, for example, and then you get a kind of set of images to choose from that you might or might not like. and the great thing is that it takes about a minute to arrive. then he needed to get things moving,

so will fed his chosen still images into another ai tool called pika and described the type of things that he wanted the characters to do. now, this sounds completely magical, doesn't it? it sounds like ai is ready to replace human illustrators and animators, but actually this seems to be a completely different creative workflow. the big advantage of the new ai tools is just the speed. it's incredibly quick to be able to build things and put scenes together. this little film took about a week to do, in and around doing some other kind of bits and pieces. the limitations are, of course, the control. and so of course it's very quick to kind of go, "oh, maybe i'll do it again and do it again and do it again." so you carry on looking. but if you get one and you go, "oh, i like everything about it, but i just want to adjust this bit, or i'd just like the trumpet to be a bit longer or i want it to be silver," it becomes difficult to control those kind of details. now, it's important to remember

always when you're dealing with this kind of stuff, that the ai doesn't understand what it's drawing. and actually that's what gives it its unique, quirky animation style. you can see in that robot there, the controls on the front, all the buttons are rippling and glitching. yeah. it can't keep them consistent over the number of frames you've animated it. so thatjust seems to be part of the thing where it doesn't necessarily understand what needs to stay the same in the animation. funnily enough, actually, there's a moment where the girl robot spins her head around, and that was something that itjust did serendipitously. i didn't ask for that, and itjust did it. i mean, it's one of the interesting things about this, the sort of serendipitous nature of it giving you something unexpected, which is also part of the creative process. and actually, you don't ask actors to perform precisely as you want them to perform. you give them the context and then you let them bring something to it, and then you choose the take you like. and so, in a way, some of the ai tools, there's

something similar about that. ringing. right on cue. this field is evolving fast. i mean, really fast. and it is now possible to control the animation so you're notjust a slave to the random machinations of the machine. i understand. this is cold call, a short film made by ryan phillips in his spare time. would you believe his dayjob is directing bbc news programmes? he's showing me the latest features of midjourney and pika. "man on street... ..on windy day." here, he's bringing a still image to life by explaining to the ai that things should blow about in the wind and also highlighting more precisely how he wants the man's head to move. the results, i have to say, are very acceptable. you can also expand the scene simply by asking for more parts of the street,

and you can even add some sunglasses just for good measure. i mean, to be honest, that could be a duran duran video. it could be. give me a couple of hours and i can make it a duran duran video. the real development here is the way that traditional movie—making skills like cgi and animation are being de—skilled. techniques that previously would've required lots of work can now be achieved simply by describing in english what you want to happen. if you wanted to change my voice the ai will listen to the audio... deep voice: ..and generate me a new one while matching the emotion.

and if you wanted to change the look of the whole scene, simply describe what you want and the ai will recognise all the objects and people in the shot and work out what it can change them to. and of course, you can alsojust turn me into someone else. the fact that this is so much easier to do now is really important, because in 2024 so many countries around the world will be having elections. and that means we're all going to have to somehow try and work out which images we see are real and which ones are not. do you think we're going to see a lot of fake footage out there that might influence elections? yeah. i'm sure that there will be attempts to influence people. but i'd advise people at this stage to start using things like our own service, bbc verify, to check information and make sure it's correct.

we are increasingly influenced by the videos of real events that we see online and on tv. we're moved to help those in need and we're angered by those who cause harm. but as the line between what's real and what's not blurs, will we become too sceptical or too gullible? will we care more or will we stop caring at all? that was incredible. and as you say, it's all about evoking a response. but how differently do you think people feel when they know something's been created by an ai rather than a person? it is a good question, because you would think people would feel differently when they knew they were looking at genuine events. but then, thinking about it, plenty of art makes us feel very strongly, doesn't it? and we know that that's fake imagery. yeah.

so how about the idea of being able to measure how art makes us feel? the v&a, london — home to 145 galleries of works from across the globe, spanning 5,000 years of art. museums like this are always looking at new ways to engage audiences. one idea here — to see how our brains react to what we're seeing. we often talk about how art makes us feel or what it gets us thinking about. well, today it's time for a way of quantifying that. so, we'rejust going to put this on your head here. 0k. itjust goes behind your ears. this muse headset, which would more commonly be used as a meditation device, has been repurposed to translate brain activity into a real—time 3d visualisation.

and this has four eeg sensors? that's right. four sensors that are on yourforehead picking up the electromagnetic activity off your brain. 0k. and what does that mean it's going to learn from me? it's going to take this raw data right off your headset. our set—up processes it in lots of different ways, which kind of indicate sort of what your brain's doing when you're looking at the art. when the brain recognises something in the visual input, for example, a face or an object like a tool or anything like that, there are certain signatures in the signal that we can pick up. and what art fund and the mill have done is use these signals, or recognise these signals in a dynamic way when the person's wearing the headset to display them in that visualisation, in 3d form, dynamically while the person is engaging with art. i've onlyjust identified that there's women dancing there. it aims to show that art isn't a passive experience.

what we wanted to show people . was that, when you go to a gallery or a museum and you see things that you recognise or that _ are challenging or inspiring or create joy in you, - that actually it absolutely has an effect on your brain. - interesting. i know what i'm looking at now, but how do i feel? do i like it? does it make me feel happy? sad? i'm not sure that i feel that much, apart from satisfaction that i finally recognised that they're dancers. i guess i'll find out. let's move on to something livelier. how about this one? there's a lot of green. there's a lot to think about here, a lot of detail, looking at the painting of the hands. hands are definitely hard to do. and the book, with the writing that's blurred. the plants... there's a lot going on, but it's very clear what everything is. there's no great moment of revelation like there was in the last one. feels kind of more upbeat. in reality, when you look at the picture, you try and think

of all the sensible things but then you get distracted. her nails look like they were painted, but they couldn't have been. how does that affect what this is reading? well, let's find out what it did discover. well, this all looks very pretty, but what does it actually represent? what you can see here is what we call corkscrewing. and you can see the ribbons are starting to kind of twist over each other and twist and bend. and that's due to sort of problem solving — you trying to make sense of what you're seeing. this was when i was looking at the degas. things seem to have got a little bit more excitable at this point. what does that mean? yeah, these golden highlights that are coming in are something that we've put into the system, and they're triggered by recognition, when you see something that you recognise. ah, that'll be the point that i saw the ladies for the first time, that looked like a blur initially. could be. and then some other things are happening. like we've isolated the beta range in your brainwave spectrum, and that's what's making the ribbons get fatter. and then we've got two... and what does that mean? he chuckles. probably means you're concentrating. it's sort of... the beta range in your...

in the brainwave spectrum is conscious thought. right, the second picture had a very different feel to it, but what i'm looking at here doesn't look that dissimilar. i can agree. it does look a little bit the same. but what we're not seeing is lots of weaving and sort of corkscrewing. what we're seeing is just nice up and down patterns. occasionally some gold highlights. i think in general what i'd say is you looked at this painting and it didn't feel unfamiliar to you or odd. you looked at it and you were quite comfortable with it. it was clear what it was of. yeah, exactly. you probably... you may have seen it before as well. what have you learned so far from people using this? the biggest variation is from one person to another — huge differences between the way one person takes in a piece of art and another, particularly people, um... neurodiverse people. people with things like adhd have a very different reaction to art. they spend a lot more time kind of reassessing the image and that stuff. we learned that as we were doing our tests. i suppose, as somebody who's not hugely into art, i was pleasantly surprised by how much i seemingly did feel.

we know that all types of visual art, for example, will engage the brain in a very similar way, and that's to engage the visual sensory part of the brain. these are signals that the brain is experiencing pretty much the entire time when we're experiencing the world around us. but, in the context of art experience, i would say it goes a little further, in the sense that we're also interested, in this...in this context, in things like the emotional state of the person and maybe inducing some positive experience in the person. although it's early days, maybe this research could ultimately prove that art is actually good for you. i'm paul carter and it's time for a look at this week's tech news. nasa has streamed an ultra—hd video of a cat back to earth from deep space —

some 19 million miles away. the is—second clip of taters the cat was sent via laser, and shows it chasing the beam. scientists hope the tech will improve communications with remote parts of the solar system. phone companies have stopped making elderly people switch to digital telephone lines, over concerns that personal emergency alarms may stop working as a result. digital phone lines have been replacing copper wiring in the uk, but they're not always reliable during power cuts. google�*s parent company, alphabet, will pay $700 million and revamp its app store to allow for greater competition. it's part of an anti—trust settlement with us states and consumers. google was accused of overcharging customers for apps, but the company admitted no wrongdoing. and finally, streaming platform twitch has been forced to u—turn on its policy on sexual content because it led to a flood

of ai—generated nudity. this week it had announced that more adult content was to be allowed — as long as it was deemed artistic. 0k. we're going to talk trees now. not the one in me lounge covered in baubles. no, i mean the many millions of brilliant big old trees that have been around for longer than any of us. now, there are people who dedicate their lives to protecting them. it's not always easy to keep them healthy or unharmed. so nick kwek has been to oxfordshire to find out how technology may be able to help. the birthplace of sir winston churchill, blenheim palace, has housed nobility and culturally important figures for centuries. but its sprawling grounds — some 12,000 acres — is also the address for other very special residents. and here in hyde park is home

to the largest collection of ancient oaks in europe, and the estate managers are keen to conserve them. what can these old trees tell us about notjust the past, but the future? you are going to feel something from being in here today that i you'll never, ever forget. i've been granted rare unrestricted access to this unesco world heritage site to see the various technologies being developed as part of a state—of—the—art digital survey of trees, some as old as a millennium. i have a very weird and wonderful title, which is head of innovation, which is very unusual for a heritage site. i can take my technology experience and come out... ..yeah, and effectively play around in these spaces, which is really, really good. david and co have created an artificially intelligent mobile app to record the forest, which uses computer vision to automatically identify species. i can come over here and i take a picture. |

it's, um. . .xylaria hypoxylon. ok, so i've got 98% probability. i have a date stamp on it, i it'll have the exact location of where we found it... because the phone knows that that's where we are? that's. .. yeah. that's where we are. and then i can also add further pictures into the database. - it becomes a legacy — - somebody can actually search for it and they can say, "ah, you know, nick. was here, certain time..." they're recording climate data, too, like weather, precipitation and also soil information. so, here, what we're looking at is all of the biodiversity that's been recorded over a previous period, and it allows us to start monitoring biodiversity change. what we can learn from these ancient woodlands can actually pass down to new trees, new plantation. hopefully we can encourage more and more to survive. so the tree is very much alive and standing. - for filipe, it's

been a game changer. i can come back at any point and i get... - my tree comes straight over here. i can then say, "ah, we found some more epiphytes, some dieback. - "ah, and we've discovered some bees living in here now?�* _ and now i've just completed another survey injust under a minute. - can i ask you a question? do you like trees? i love trees. i love nature. these are really rare. i mean, only 7% of the uk'513% woodland is in a good state. - the fact that we've actually got one or two, even three — _ these are diamonds. they're so precious. the estate serves as a living laboratory for academic researchers. there's three cameras on this device. you can see it there. hello! say hi to the camera. hi! they're digitally mapping the woods in 3d, using lidar scanners that they've placed on the back of legged robots and drones —

and, today, on lintong's back. we want an overview of the whole forest because, say, you want your most prominent trees to grow better, so you might have to measure the diameter, right? that's what we need this 3d model of them for. and their system, they say, is pretty precise. let's say 100 metre, it will still give you sort of maybe a couple centimetre accuracy. yeah? to help forestry management to make decisions about... branch clacks on camera. ..let�*s say... oop! careful! ijust got caught on a little bit of twig. yeah, it happens. of course, this isn'tjust about trees, but their vital role in our wider ecosystem. in here, you can have over 2,000 species dependent on an oak. - over 200 directly, specifically involved in an oak. _ time to see what all the fuss is about. oh, my goodness me. there it is! isn't that a beauty? nick gasps.

it really is such a magical, beautiful thing to be standing in the presence of something that's alive and over 1,000 years old. it makes you think about the importance that technology can play here in helping keep this thing for future generations to enjoy. that was nick, and that's nearly it from us and 2023 as a whole. yeah, what a year it's been. thank you so much for being with us over the last 12 months. we'll be back in the new year. but, in the meantime, we thought we'd leave you with a quick whizz through our favourite bits from �*23. thanks for watching and we'll have more in 202a. british military training adapts to new threats all of the time. this might look like a mannequin that's been repurposed as a target, but this target shoots back. ugh, the stench! that is absolutely overwhelming.

hello. while we'll still see blustery showers around today, it is relatively quiet, compared to what is either side of it. after the storms earlier in the week, another deep area of low pressure this weekend. if you are on the move keep across the forecast because there will be some fairly heavy rain, risk of flooding, and impacts from snow too. strong to gale force winds. the main impact from that will be at the centre of the low, though, west of ireland as we go through saturday. we could still see gales top and tail the country is that rain and snow sweeps eastwards. that is coming up. more details in a minute. back to the here and now. we continue with the rest of the afternoon with cloud across northern parts of england, northern ireland, far south west of scotland. outbreaks of rain. to the south of it some sunshine, a few staying dry, a few scattered showers around and a blustery wind. to the north of it, a chilly day with wintry showers in the north of scotland. but through central areas and into the glasgow and edinburgh region this is where we will stay dry with the sunshine. tonight that band of cloud,

rain and snow will fizzle out. wet and windy with some wintriness in the far north—east of scotland. as the next area of rain pushes in, temperatures will rise later in the night, but not before they drop down into lower single into lower single figures, maybe as low as —7 in parts of scotland. a cold start to the weekend. dry and bright start the early risers in the north and the east. cloud and rain already developing in the west. heaviest in northern ireland and then spreading its way north eastwards. could see snow for a brief time in northern ireland. the hills of northern england, before turning back to rain. temperatures rising towards the south and east. we will see some dry weather through the afternoon. up to 15 degrees. a lot of cloud here. cold across scotland and again some of the roads could be impacted by some heavy snowfall as we go through the second half of saturday. the a9, a82, a83. it will turn back to rain later on. another band of rain sweeps eastwards through the latter stage of saturday across england and wales. that clears out into sunday. sunshine and showers is the name

of the game for new year's eve. windiest down towards the english channel and across shetland. we could see winds of 60 to 70 miles an hour. lighter winds, slow—moving showers in the centre. we could see some large rainfall totals for one or two, but others may stay dry. as we head up to the midnight hour and welcome in 2024, it is going to be a little bit cooler, but nothing desperately chilly, with some further showers around and still windy in the far south. take care.

live from london. this is bbc news. ukraine says russia has launched a massive air attack overnight with explosions reported across the country. ten people are reported killed. the top election official in the us state of maine rules that donald trump cannot run for president next year in the state. israel expands its ground offensive into palestinian refugee camps in central gaza, forcing thousands to flee. hello, i'm sarah campbell.

ukrainian president, volodymyr zelensky, says that russia has targeted his country with 158 missiles and drones in the past 2a hours — shooting down 114 of them. at least ten people have been killed after cities across ukraine came under attack. this was the scene this morning in the capital kyiv, where at least three powerful explosions were heard in the city centre. odesa, dnipro and kharkiv are among other cities hit. ukraine's air force says it has "never seen so many locations targeted simultaneously". in the last few minutes the polish ministry said an unidentified aerial object has entered its airspace. they say the object was tracked by the radar until the signal disappeared. james waterhouse gave
