which is straight after this programme. this week — shiona is in barcelona, which is full of the newest mobile tech, but where the wearables know too much. how old is spencer kelly from the bbc? spencer kelly's - currently 50 years old. blatant lies! to be fair, he does look good for his age! you wish! meanwhile, eye—eye, what's this? a phone you can control with just your peepers? also — the politics of deep fakes. we're being told not to believe everything that we see, but what do we do when the

lawmakers deepfake themselves? in the argentinian elections, we saw both candidates using ai—generated images, making themselves look like heroes. and should ancient artefacts stay in a museum, or be taken home? it's a hot topic right now, but alasdair�*s been looking at a digital halfway house. the cool thing about ar is you can see it as it looks now, but also how it will have looked in the past. exactly, how it - originally looked, right? welcome to mobile world congress — or mwc. with1.4 billion phones sold a year — that's 28 phones a second — it's no wonder industry events like these in barcelona take place, and i'm excited to see what's happening.

from the honor magic v2, with its ground—breaking slimness — less than one centimetre when folded... it's so thin and so lightweight, this one. ..to motorola's latest design that rolls round your wrist, and lenovo's laptop with a transparent display — all the biggest names are here, fighting for my attention. one of the major talking points of the tech world has been the samsung galaxy ring, and this is the first time it has been officially revealed. i think the most important thing is to say, what value are we presenting to our users? and i would say it's in three areas. one is obviously the things you would expect, like steps and activity, heart rate. and then there's the area of sleep, particularly around sleep stages, movement during sleep, heart—rate variability during sleep.

and then lastly, women's health — using skin—temperature sensors to detect trends of change to essentially predict the window of fertility for women. so what does the medical field think about this? do you think that there will be genuine diagnostic developments as a result of monitoring this type of data? so i think it's an evolution. i think there is generally a blurring of the lines of what was once a consumer device versus a medical device. and those things are becoming a little blurry now. it really does seem like it's this new minimalist era for wearables that we're seeing emerging. i can't hear anything now. ah, because you're recording a video. i'm recording a video — how did i do that? there's a real buzz around humane ai�*s pin, and this is the first time it's been shown in europe. i'm looking forward to trying this. here's the ai pin — there's two components. that one goes behind one layer of clothing, and this one just goes on top. so you can just attach like that — and that's it.

once you clip the ai pin to your clothes with a magnet, you can talk to it. what are the three top sights to see while i'm in barcelona? and it'll answer questions by voice, like your own personal assistant. pin: the three best sights. in barcelona are la sagrada familia, parc guell, - and la pedrera—casa mila. and there's a two—finger gesture that i do, as well. what are some great seafood restaurants around here? quins son els millors de marisc per aqui? i and what was the difference, then, between the one and the two? so one isjust any kind of question that you might have about anything. and then two, really, is about translation. so itjust locks in translation, and you can have it translate in up to 50 languages. wow, ok. if you don't want to hear it, then just look at the answer, which will be projected using a laser onto the palm of your hand, and to use the controls, gesture with your fingers.

you had a little demo with your husband in there. there was a few things i wanted to ask you. absolutely. because it takes photos and videos as well. can you tell me how you can do that? yeah, so one big part of it is about allowing you to capture memories. and those memories can come in the form of things you tell it to remember. so treating it like a second brain, but also capturing moments that you normally would take your phone out of your pocket and be living your life through a display. instead, you can use the device to do it for you. so all you have to do is do two fingers — quick double tap to take a picture. 0k. just like that. perfect, and you can see it's got the camera on the top there. yes, and so, whenever the cameras are on or active, or the microphone is active, the led — called our trust light — is on at the top. of course, it's artificial intelligence that's powering

humane's ai pin. how old is spencer kelly from the bbc? spencer kelly from the bbc is currently 50 years old. i 50 years old — to be fair, he does look good for his age. and ai is a strong theme for the next generation of smartphones, too. just circle what you're looking for and you get your answer. anything in your instagram feed or a photograph that someone sends you, you canjust circle it and immediately initiate a search result. so that's using both, obviously, visual search and ai. and these are obviously new phones. is it only people that are making a recent purchase that will have access to these features? so anyone who bought an $23 or an $23 fe last year, as well as our foldables and our tablet, actually, top end of our market in tablet, you're going to get the galaxy ai features rolled out later on this year. but what happens to all this new technology after it's no longer fresh out the box? well, sadly, overfive billion mobiles were thrown away last year. many people keep their old tech rather than recycling it.

and with the growth of ai putting even more stress on networks, the need for environmental responsibility is even greater. a newer phone in great condition might go straight back out to a customer with a little bit of a buff and polish. a broken phone will come in and it'll get repaired and go back out to another customer. and a really smashed phone will still come back in and be harvested for parts that can then be used to repair other phones. how difficult is it to change attitudes when it comes to this type of thing? we're going to continue to innovate and that's a fantastic thing. and we see that here today. but if we are continuing tojust consume, consume, consume, consume, without driving the re—use and ultimately the recycling at the end of the technology's useful life, then we are just digging more and more minerals out of the ground.

so, if we really want to save the planet, it looks like it'll have to be an effort from both the phone companies and ourselves. that was shiona, and we'll have more of the tech showcase at mwc later in the programme. now, it was actually on our mobile devices that augmented reality first came to prominence. you look at your screen and it'll add something virtual to the real space that you're in at the time. originally, many may have disregarded it as something playful orjust for gaming. now, though, it's being used in health care, education and entertainment. yeah, and alasdair keane has been to meet one artist who's using the tech to display historical artefacts, found in museums around the world, back in the countries they originate from. looty is more than just, like, an arts collective. we kind of intersect between, like, arts, tech, activism and history.

the whole inspiration for me came from a unesco report that said that 90% of all artwork and artefacts based in africa actually live outside of africa. and that was something that, like, was deeply unsettling for me. but also, you know, something that i've always wanted to have some sort of hand to, like, change. looty describe their project as a digital heist. they capture objects on display in the british museum digitally, but say this doesn't break the museum's rules, which allow 3d scanning by visitors for noncommercial use. we're using lidar technology, so making scans, going around, you know, the different artefacts, scanning them and then taking that data that we've retrieved and then using those for, you know, ai experiences, nfts, and different installations as well.

their most recent project involved the rosetta stone — an ancient slab used by egyptians to study hieroglyphics. using free software from the company snap, they were able to display it virtually in egypt. the actual position where the rosetta stone is from is a citadel in rashid. simply, you just need a ai—enabled device, snapchat, and then you can view that in its position in rashid. lens studio has this technology called custom location ar, which is basically where you can geolocate a digital asset or, you know, a digital thing in its actual position. it starts with the story. the rosetta stone, known as the hajar rashid. and this appears before people in scale of what it is. and the cool thing about ar is you can see it as it looks now, but also how it will have looked in the past. exactly — how it

originally looked, right? and what a lot of people don't know is that it's actually a fracture of the original stone. so part of ourjourney was to, like, actually rebuild the rosetta stone. what do you hope people get out of using this, and experiencing this? with this whole, like, digitisation of artefacts, i see this more as something that's for the future and for the younger generation. and most of the user base for, like, snapchat is, you know, people that are a lot younger than me, like the gen zs and things like that. so i saw this as, like, the best app, but then also, because of the ease of the use for the technology. where and how objects are displayed is often debated. the british museum told us there has been no formal request from the egyptian government for the rosetta stone to be repatriated and they say they work with colleagues there

on exhibitions and research. there should be at least alternative methods, right, for us to engage with culture and history, you know? like, that are commercialised as well. notjust having, like, the institution of the museum running, like, the whole show. i guess they would say, though, they are engaging in that. the very fact that you're allowed to go into the museum and take a 3d scan — and they would say they're doing this themselves and working with lots of different projects around the world. yeah, it's true, iwant, like, because i remember when i saw that in their terms and conditions, that you're allowed to make a 3d scan, iwasjust, like, why they would put that in the terms and conditions? but maybe they never thought of somebody like me going in and doing this, and actually thinking about, you know, a digital repatriation. maybe they didn't think that was something that's important — which, even if you think about today, is probably not so much important today, but for the future, i definitely believe that the digital

is going to be the future. time for a look at this week's tech news. hundreds of thousands of meta users were unable to use facebook, messenger, or instagram on tuesday after a worldwide outage. meta apologised to those affected and said it had resolved the problem as quickly as it could. a satellite has been launched to pinpoint oil and gas industry methane emissions in space. the methane set is backed by google and the environmental defence fund group. this understanding of emissions, where and how much methane is being emitted will allow us to track these emissions over time. it'll be orbiting the earth 15 times a day. the value of the crypto—currency bitcoin briefly reached an all—time high of more $69,000 on tuesday. the spike occurred after some wall street institutes bought billions of dollars�* worth of bitcoin assets,

following approval by the us financial regulator. and researchers at the california institute of technology are hoping that hat—wearing jellyfish can help them find out more about the state of the planet. the fashion accessories actually contain an array of electronics that gather data about the ocean. jellyfish do not have a brain or the ability to sense pain — so don't worry, they aren't harmed by the experiment. pop star taylor swift, and politicians such as us presidentjoe biden... it's important that you save your vote for the november election. ..uk labour leader keir starmer... no, i'm sick of it. ..and london's mayor, sadiq khan, have all found themselves victims of deepfakes in recent months. i control the police. they will do as the mayor of london tells them, - and obey orders. whether it's fake explicit images or audio recordings of conversations that haven't ever happened,

dodgy deepfakes created using readily—available ai—powered tools have spread like wildfire across social media, sowing seeds of mistrust and blurring the lines between reality and often malicious fiction. but in this confused and confusing landscape, what happens when politicians use deepfake technology themselves? to find out, we need to take a trip from the big smoke to the big apple. attention�*s focused here in lower manhattan, new york city hall. it's become almost commonplace for bad actors to deepfake politicians, but it's unusual for politicians to deepfake themselves. that's something that the mayor of new york has actually done. towards the end of last year, mayor of new york eric adams revealed in a press conference that he'd used deepfake technology to make a series of automated or robocalls to nyc residents.

in these calls, which mainly promoted the hiring of venues owned by the city, the mayor was able to speak a variety of languages, including mandarin, cantonese and spanish, using deepfake tech. these actions have raised more than a few eyebrows in certain quarters. to find out more, i needed to leave manhattan and head to brooklyn. it's here i caught up with civil rights and privacy campaigner albert fox cahn. he believes the mayor's use of ai sets a dangerous precedent. and to me, it's reallyjust this alarming wake—up call about the potential for abuse of these deepfake technologies. when you normalise the use of this sort of deepfake technology, when you use it to convey authentic government announcements, then you're basically educating the public that deepfakes are reliable, that you should trust what you hear in a deepfake. there's huge potential to use deepfakes to really undermine trust in government and trust in our institutions.

the mayor's office declined our request for an interview, but eric adams has publicly stated new york city will be doing more stuff with al, and will use it, and not abuse it. political use of this technology is on the rise around the world. henry ajder is an authority on deepfakes and ai. this isn'tjust a western phenomenon, it's really global. and one that really springs to mind happened in india, where a bjp candidate — that's the ruling party — used a similar technology to essentially speak different regional dialects that he couldn't actually speak. and in this example, it wasn't disclosed clearly to the audience that this was ai—generated. and when it emerged that it was, the actual bjp party disowned this use and kind of decried it as something that they didn't want. and then, more recently, in indonesian elections that happened earlier this year, we saw an avatar of a synthetically—resurrected deceased previous leader coming

back to endorse one of the candidates. president indonesia... but in the argentinian elections late last year, we saw both candidates using ai—generated images to depict the opponents as weak — but also to embolden themselves, making them look like heroes or strong men. my concern, i guess, is that if we do start to see politicians really embracing this and this is becoming a much more high—volume form of political communication, it will lead to increasing distrust in media of politicians more broadly. there's an estimated two billion people voting in elections across the globe this year. the stakes have never been higher when it comes to determining political fact from fake. spencer: that was marc — well, at least it sounded like him. anyway, we started the show at the mobile world congress, so let's finish with another face—off with a phone.

spaghetti western music i'm about to do something very cool with my eyes. engine starts yeah, i'vejust turned on a car by looking at an icon on a phone. if the sensor at the top detects that your eyes have fixed on a particular part of the screen for 1.8 seconds, it treats it like a click. this phone, the honor magic 6 pro, has been using this gaze control to allow users in china to look at incoming notifications and open the messages. this expanded proof—of—concept demo gives me a wider choice of actions — basically,

controlling a car! i mean, it's all very knight rider, isn't it, really? just to be clear here — this is not a demo of eye—controlled driving, but it is a signal that your devices might soon know what you want to do, without you even touching them. we're at a period in time where the interaction with devices is arguably at the cusp of changing. this could be transformational in the way in which we engage with devices in future. there's been a bit of a buzz around eye control recently — mainly thanks to the apple vision pro headset. you don't use controllers with it, you just make a gesture with your fingers while looking at the thing you want to select. and it's got people wondering whether looking is the new pointing. so it could be that you look at a landmark, and then you get some information in your line of sight as to what that

could be. it could be that you look at an appliance, and perhaps that could have something happening as a result of your gaze. so it's almost limited by your imagination. and i think what a lot of the companies working on this are hoping is that they will create the toolset for people to be able to do this. and then very bright application developers will go off and innovate in all sorts of directions. is it hard to do this? doing this on a smartphone is arguably much harder than doing it on something like apple's vision pro. you have a ski mask on your face, six cameras pointing at your iris, and it can very, very accurately pinpoint what you're looking at. on a smartphone, you're having to use a sensor on the front of the device in an open environment and actually assess what someone's looking at, and then invoke some kind of action as a result of that. that's a complex task. one thing i've noticed while using this is my eyes don't stick on one exact part of the screen for any particular length of time — they kind of dart about a bit. so the challenge for any designer of an eye—control system is they really have

to know what bit you do want to activate, and not accidentally delete your emails just cos your eye goes a bit funny! but being able to work out where your eyes are pointing is just one consequence of something that's only happened in the last year — the arrival of real ai on your phone. now, i'm not talking about the ai that you've probably been using recently, like those conversations you've been having with that large language model or those weird pictures you've been creating. see, that's not your phone doing the work. it's only been showing you the results from huge ai data centres in the cloud. but now there's a new type of processor which is being put into phones, and which is bringing true ai onto your device. it's called an npu — a neural processing unit — and it's tailor—made to handle the complex calculations performed by neural networks.

this is going to make all sorts of things possible because the phone can be using that intelligence all the time to almost be predictive, where you'll look at the phone and you'll interact with the phone, and it will almost know what you want to do before you even want to do it. and this is also making other capabilities like real—time translation possible. it's making the processing of images to fill in gaps in an image if you rotate it, for example, possible on device very, very quickly. one additional benefit for consumers, however, is the fact that if all of that computation is done on the device, there are some good privacy benefits because it means your data isn't leaving the device and going up into the cloud where you relinquish control of it. so i think we can expect to see more phones doing more intelligent things in the months to come, as manufacturers experiment

with new ai capabilities on their devices. interfaces are changing, ai is evolving. but most importantly right now, i need to park the car. and that's all we've got time for. yeah, thanks for watching and we will see you soon. bye. hello there. friday was a very warm day for april. temperatures widely reached the high teens and the warmest spots had temperatures a bit higher than that. 21.5 degrees celsius was recorded at both st james' park and northolt, both in greater london, making it the warmest day of the year so far. we have something of a change in the weather forecast, though, for saturday. cooler air is going to be arriving across both scotland and northern ireland behind this cold front.

and that's significant because scotland also recorded its warmest day of 2024 as well on friday — 20.2 degrees celsius in fyvie castle. but across scotland and northern ireland, temperatures widely will be dropping by around five or six degrees celsius into saturday. so you will notice that significant change. right now the weather is quite quiet, though. we've got a few patches of high cloud around, one or two areas of mist and fog and a few showers coming in across northern areas with the winds strengthening slightly. temperatures as we start saturday morning around 8 to 11 degrees celsius. we're looking at a mild start to the day. now, a band of rain, a cold front will quickly swing its way into northern ireland and scotland. as that moves eastwards, what will follow is blustery showers with some hailstorms mixed in the winds gusting up to 50 miles an hour further southwards. now a patch of rain for northern england and across wales, otherwise largely dry. much cooler air across scotland and northern ireland arrives through the afternoon,

whereas across england and wales it's going to be the last of the really warm days. temperatures, i suspect, will reach around 21 or 22 in the warmest areas of eastern england, with colder air arriving across most parts of england and wales after dark. well, that takes us into sunday's forecast. and sunday is going to be a blustery day for scotland and northern ireland. frequent showers here, some of them with hail and thunder mixed in. there will be a few showers developing through the day across northern england and wales, but it may well stay largely dry across east anglia and the south of england. wherever you are, temperatures will be much closer to average, 15 degrees in london. so a big change from the low 20s that we'll have on saturday, it will feel cooler. on into the start of the new week, monday sees low pressure move in off the atlantic with this cold front diving its way southwards across the country. and that's going to be bringing a spell of rain followed by showers, showery weather conditions around for tuesday and for wednesday. but the weather should become drier and a bit warmer towards the end of next week. bye for now.

live from washington, this is bbc news. the us says, the threat of an iranian attack on israel is real and viable,

as president biden issues a clear warning to iran. un agencies say parts of sudan may tip into famine if the civil war continues. we'll have rare pictures from the ground. russia targets critical infrastructure in ukraine, as us aid to the country remains stalled. hello, i'm helena humphrey, glad you could join me. us presidentjoe biden is warning iran not to take military action against israel, as the us government says such an attack could happen imminently. iran vowed to retaliate after an apparent israeli airstrike on its consulate in syria killed at least thirteen people, including a senior military commander. that attack was condemned by the un's secretary—general, who said diplomatic and consular premises are off limits under international law. now, nearly two weeks later, american officials

are telling cbs news that an iranian strike on israel could come at any moment.
