this is bbc news, the headlines: ukraine says at least 50 people are dead and dozens wounded after a rocket hit a train station in the eastern city of kramatorsk. kramatorsk had become a major hub in the war for civilian evacuations from the donbas region. it's now the focal point of vladimir putin's war effort. slovakia has donated its entire 5—300 surface—to—air missile system to ukraine. the country's prime minister said it would save many innocent lives from moscow's aggression. uk prime minister borisjohnson says his country will send another $130 million worth

of military equipment to help it resist russian attacks. the body that hands out the oscars has banned the actor will smith from all its events for ten years after he slapped the presenter chris rock. but the academy stopped short of revoking his best actor award — it described his behaviour as unacceptable and harmful. now on bbc news, click. this week, another chance to see our return to the mobile world conference. we're going up a mountain with this good girl. and the vfx behind the matrix resurrections. mobile world congress. every year, barcelona used to be lit up with smartphone

launches and announcements of connected devices, beyond what you might ever think of or need. now, 2020 was pretty much a no—show, for obvious reasons, and last year — well, that was just weird. we've arrived. this is fira de barcelona. yes, the show was back on, but we couldn't go — although you were there in spirit, if not in body. yeah, the less said about that, the better. but this year, it's back in full swing with all sorts of companies showing off their latest wares. so, whilst i'm here at the design museum in london, where behind me, there's a good old—fashioned brick phone and a nokia 3310 — remember those? — we know how fast these phones change, so we've sent omar mehtab and osman iqbal to barcelona. samsung, nokia, huawei, oppo, xiaomi — they're all here and all got something to show. that's the thing about mwc, isn't it? it's all about the big releases. say, for example, this — the samsung s22 ultra.

the supposedly best of their s22 range, it comes with a touch bigger screen than its predecessor, a slightly more powerful cpu and a bigger sensor, so its cameras can take better pictures in low light. but they have learnt from the s21 ultra, because instead of flogging a £60 case to house the optional s pen, they've just given it to you, in here, and they've got a little slot for it within the phone, which potentially spells the end of the note series? who knows. but what i can say is this does write smooth. you know, like a pen on paper. the problem is in some tests, the battery life is actually a little bit worse than the s21 ultra and its square design doesn't feel as natural in your hand, either. and at £1,200, you wonder if it's worth the huge price tag with such little differences. but it pairs well with this — the newly announced galaxy book 2 pro. this is the most powerful

of its line—up, the 360, and it starts at around £1,099. it offers a few interesting titbits, like a 1080p front—facing camera and auto framing, which keeps you centred in your shot — for your video calls that undoubtedly became more popular over the last two years. can't find me! there it is! it's found me! but the multi control impressed the most, where you can keep watch of your smartphone and also use your tab s8 as a second screen, creating quite an ecosystem. samsung stands for innovation, you know? typically where we lead, others follow. bringing all of those the elements of the note and bringing them to the s22 because we listened to our customers — they wanted that productivity, they wanted that solution from us. innovation and what our consumers tell us they want will be at the absolute heart of what we do going forward. and here's the problem — that's it. with smartphones, we've been held in a kind of a holding pattern for years with only incremental upgrades every release. once you've seen one, you've seen them all, and despite how impressive these handsets are, it's all kind of predictable.

here's another example. huawei's latest p50 pro is just another smartphone with small upgrades since the last. and this super device software, which they announced at the show, is, again, incredible, but just another ecosystem they've built to bow against the likes of apple and samsung. look, here's the point i'm trying to make, ok? here are some releases from some of the big companies. and here are the notable improvements from their predecessors — camera quality, battery life, screen size. is that all we've got to look forward to anymore? ok, yes, in recent times, we've had some exciting innovations, like the foldable or the rollable smartphones. one noticeable trend is cheaper, but feature—packed phones, like from xiaomi here, or going a bit more retro again, like nokia. but otherwise, it'sjust variations of the same thing, and has been since apple debuted the iphone 15 years ago.

giant screen. applause can we really call that innovation? is there a point to mwc if all you're going to do is go and look at a phone and say, "oh, look — that camera lens is bigger." there's innovation in the form factor, but there's all in — also innovation in the connectivity and the content. we've seen the content ecosystem basically develop over the last years as well, so i think with every touch point that the — that the phone essentially enables, you'll also find subsequent innovation come from that. ok, yes, innovations involving phones, but not the phone itself. look, it's no—one�*s fault, but the next killer device just hasn't arrived yet, and so, it's all a bit samey. so, maybe it's not worth coming to mwc again. there's nothing really special out on show. it's not just about the glitzy phone launches, is it? it's not just shiny things. there's a big mobile ecosystem and loads happening. i get that, but people care about the big phone launches.

you don't get that, though, do you? what they may upgrade to next — that's what matters here to people. is that what matters?! of course it is! there's loads of stuff going on! you know, there's loads kind of innovation, small players, big players. i'll show you something so intense. cheer up! so, what are these companies working on in 2022? sg bartenders, robot dogs, vr roller—coasters and, you guessed it, the metaverse! and as i finally get back to an in—person event, i'm being made very aware that companies are eager for me to embrace the virtual world. but here's one device that is 100% metaverse—proof. as screens get bigger and bigger, what happens if you make a phone with no screen at all? no buttons, no screen, purely voice controlled. put it on and, sayonara, social media. these are titan from mymanu. they are lig—enable earbuds with a phone's functionality,

and they can even translate other languages in almost real—time while not needing to connect to a phone like most other devices. why don't you tell me an interesting fact about yourself? speaks french so, you're french, you're from the sunny coast and you live in manchester, where it rains all the time. exactly. that's cool. that is awesome, that is awesome — i love that. and whilst one company is ditching the screen, the astro slide 56 is adding even more to it. a regular rectangular phone — where is the innovation? watch this. boom! it's a mechanical keyboard on a phone! and whilst i may enjoy a keyboard on a phone, it doesn't exactly scream rock star. but this does. zurich—based start—up

mictic have developed what they are calling audio—augmented reality. these wristbands connect to a smartphone app and the sensors translate your motions into music. when you think of a cello, here's the neck of the cello and then my right hand is the bow hand, so it would essentially be like... plays cello that's all very cultured but, let's be honest, nobody plays the air cello. i'll throw a beat behind it. now, i can start really rocking out. plays electric guitar but the final word has to go to japanese company toraru who have found a truly novel way of transporting people to the other side of the world. this is a live video link to japan. someone is standing there with a tablet and you have these buttons along the bottom and all you do, if you want to turn around, you just press your button. look at that!

you can even push buttons to pick things up or even pay for goods. but some parts do feel a bit dehumanising. and ifeel super guilty about this — is this button here. and i don't know why, but you can go boop! and they jump! that was a big jump! the buttons that make other humans jump should just not exist. osman and omar, ola! it sounds like some companies are breaking new ground there, so has the visit to the show been worth it? for me? no, it hasn't, because it's the same as every other mwc that i've been to. a new smartphone with a couple of improvements from the last one. see, that's - absolutely not true! i've been trying to tell omar all along _ it's notjust - about these devices, it's about the wider ecosystem. we've seen the metaverse and the advancement i in connectivity needed. that conversation is happening. 56 low latency, things that are around the phone — - that's where the - innovation will happen.

but there's nothing to see. there is no metaverse as yet, that's the point. yeah, it — because it needs these conferences like this| to sit down, get it done, advances connectivity. . it's not just about that. but the reason people care about these conferences is because of the smartphones, the main devices. not secondary things, you know? it's all about the smartphones. ok, you're like an old married couple. he's such a pessimist! i'm going to leave you to keep battling this out. you are such a pessimist! we've got the optimist and the pessimist here. osman and omar, thank you. back in 2016, i met hitoshi araki, creator of a prototype augmented reality game called hado where players had to blast away their opponent's shields with fireballs. it was brilliant fun and what's even more brilliant is that six years on, hado is now a serious sport, played competitively in 28 countries. and now, i've been invited back to play against

a former uk champion in a match with a difference. see, tom park is not in the same room as me. we're being connected using 5g, and this is an occasion where any delay across the network can seriously spoil the fun. most people, when you think about 5g, think about moving large amounts of data. we are not, we're moving very small amounts, but it has to arrive in the right order and it has to arrive quickly. i could have done with a bit of lag, to be honest. where is he? oh, i've got him, i've got him! it's like they have attached it to a cat or something, haven't they? we have already done matches in the uk between different cities, and what we're looking to do is matches between different european countries. especially at the moment, travel is difficult. where is he, where is he? and it allows experienced teams to actually be able to play and train against each other, and the next stage on from that will allow us to get teams in tokyo, who are the best in the world, no question, to be able to train us without having to get on a plane to go there. and the reason that we're here is to see the cambridge

wireless 5g testbed in action, which allows companies to experiment with how best to make use of the technology's speed and features, and understand its limitations. the testbed facility here at cambridge wireless allows you to put artificial lag, artificial stutter into the system, which means you can effectively try and push the data packets out of order with each other, you can delay them arriving, and you can see how much you can cause problems with the system before you start to get a breakdown in the end result you want to achieve, and, therefore, know what you can operate within. what 56 would really like to exploit is what we see in the industry, where we can see manufacturing applications that we simply were not capable of delivering before. really what it means it us to control things at a long distance in real—time. ok, here's a different example of how 5g can stream a lot of data very quickly, and it's a more relaxed demo — well, for me at least. i'm driving this robot

around the car park, and, in a moment, iam going to try and do something that may one day be needed in disaster zones and medical emergencies. myjob is to somehow get this multi—jointed monstrosity to grab this bag of fake blood and load it into this container. sounds easy, might be messy, but it turns out that in vr it actually isn't that bad. i have to say this is much more intuitive than i thought it was going to be. i thought i was going to have to somehow embody a multi—jointed robot, but it is just a case of dragging the arm around to where i want it. lifting up the bag of blood... and... and if you look below you, there is a basket you canjust lift it over there... swinging the blood bag into the basket. bingo. perfect. nice! and so the idea with this is then that this could be happening anywhere in the world. exactly, anywhere — you could be in china doing this, you could be in low earth orbit, you could be down a mine

shaft, and yeah, you can sit comfortably in your office and control a robot from wherever you need to be. now, i will be honest, there is a very slight lag, but for what i am trying to do, i think that lag is totally manageable. job done, blood delivered. well done, goodjob. yeah, it's all very easily when you are just pootling around a car park. but now it is time to see how this can all be done in the wild. here's paul carter. the yorkshire dales national park in the north of england — a favoured destination for walkers, hikers and climbers. in the event that any of them get into difficulty, it's the volunteers of swaledale mountain rescue who go out to help. i am spending two full days with them during the changeable and challenging conditions of storm eunice to see how tech can make a difference.

as beautiful as the landscapes right here can be, in conditions like today, they can be pretty treacherous — especially for emergency services like mountain rescue. and one of the biggest problems they face is the complete lack of any mobile phone coverage. i mean, i've got absolutely nothing. so what the team here are doing is they are trialling a range of solutions, utilising 5g technology, to help make their lives easier, and also to help save lives. one of the best tools in a rescue team's arsenal is still of the canine variety. this is kez, a mountain search dog and all around very good girl. you want to throw the ball? good girl! what she doesn't know is, thanks to the 5g network that has been installed here, her every move on the hillsides can be tracked remotely. back at base, we can see where she is going on a tablet. that's the dog on the screen there?

yeah, just there, it is a little bit greyed out but he is running around, he's moving a bit. all of this is possible because of equipment stored at the temporary base station. what we have here is a mobile base, a 5g mobile base station, we bring it with us to fill the coverage where there isn't. it uses a closed mobile frequency spectrum backed up by an internet connection via starlink satellites, which allow the team and people back at base to share communications, audio and video, and data at low latency and high speed. communications is vital to the team, it's vital to the casualty we are looking for and eventually find. the possibilities are endless. there is no greater need for speed than when lives are in danger. smrt took us out in the now driving rain to see a full—scale medical rescue drill in action. and just how important sharing

data quickly in such scenarios can be. a0 minutes ago, the police called the team to tell us there was an injured walker somewhere up the hill there. this is a 56 non—standalone system, we have two antennas, one here and one up there. we attach this to the wall because of the complexity of the weather conditions today. we did a range test and we reached all the way up to the hill, to the top of this hill here with full bars of 56. this rapidly deployed 5g network allows the rescue team to use medical devices to monitor the casualty on a phone and transmit this back to the crew at the base station. the remote monitoring devices mean the rescue crew don't have to stop to check the patient as they head down the mountain, and medical staff at base can keep an eye out while the crew are concentrating on navigating difficult terrain.

so i am getting enough information here to tell me that i am happy with the casualty, so the lower doesn't have to stop at any point. for the volunteers, working at night brings extra challenges. using infrared and thermal imaging, which can also be streamed remotely, the team can locate casualties more easily. there may be something just beside this wall. this is currently all an ongoing trial. it's a partnership between several bodies including safenetics, north yorkshire council, smrt and local universities. for these guys, where conditions can change any minute, connectivity is absolutely crucial. some of these ideas are still in their infancy, and logistically there are hurdles still to be overcome. but who knows — if you ever find yourself needing to be located by a search dog, you never know, shejust might be more on the grid than you are. dog barks.

i think paul may have made a new best friend there. now this time of year is movie nomination season, and for us at click that also means the opportunity to talk to some of the greatest minds in visual effects to see what they have been up to over the past year. first up, a look at the bafta—nominated matrix: resurrections. i've had dreams that weren'tjust dreams. am i crazy? we don't use that word in here. for me, getting on board with the matrix was huge. i think a lot of people in this industry will probably have had the matrix affect them in different ways. there was a huge expectation on the movie's shoulders, but also on vfx, obviously we're revisiting a world that had been created 20 years ago, so we knew these assets were alive somewhere, we just had to try and track them down and find them. and it wasn't, sadly,

the case that they all just live in a nice hard drive, and we can just ask warner brothers, "hey, can we have the assets?", and they send them to us. lots of e—mail threads, different people, old companies trying to look through their backups and finding whatever they can. we eventually managed to restore, i think, a sentinel, a harvester and a foetus egg stalk. we found all the files but then we were like, how do we open it? we found an old version of the file that we could open it, export it in a different way and then be able to pull it in. they needed upgrading. they were built a long time ago, topology is different, textures we always had to redo. so they gave us a perfect starting point to build on. and it was even just exciting opening those assets, "this is from the first matrix, this is wicked!" getting to spin around the models and see how they were made, it was really cool. we did add more details, the way the geometry intersected, and the way it was previously built, so we upped the detail, and upped the resolution —

we are a 4k movie, so we had to make sure it held up in ak, where the previous versions needed a bit of a boost. the same with the foetus fields and foetus eggs, again we kept the overall design, we kept the foetus baby exactly the same, we just extended the stalks and added more detail, more cables. that fit in with the story in this case, because this is 60 years, time has passed, and the machines have sort of evolved their harvesting methods to draw more power so we have the cable. io city is sort of the new zion of this movie, like the expanded city. that was one of our biggest builds. we had to break it down into lot of small sections, we wanted to try and create a believable city that you could feel people have lived there for a while and they have figured out how to — irrigation channels, farming, dwellings, we tried to block out these different areas that you could buy as real, and then populate it with little people, little chimney stacks, atmospherics, it was set in a huge cabin so we want to make sure we have a sense of scale. our vfx work will always be better if we are building off the back of something real, or if we have something real

to reference before we build out the effects. it will always look better, you can create whatever you like, you can create wonderful environments, as much imagination as you like, but as soon as you start putting something real into it you just need something to ground it. and i think if you do a partial set build of exactly the kind of idea that you want, you want to light your characters in a certain way, the background behaves a certain way behind them, so once you have got something captured on camera it is so much easier to extend that in cg and build on the same thing, and you know, be a part of that. after all these years, to be going back to where it all started? back to the matrix. great work, and next week we will have the second in our visual effects series, not to be missed. that's it for this week though, as ever you can keep up with the team on social media, find us on you instagram, facebook and twitter and @bbcclick. thanks for watching, bye—bye.

today was not quite as cold as yesterday, because the wind wasn't as strong, but we have still ended the week with temperatures below par for the time of year. we take that chilly arctic air into the start of the weekend with us. however, as we move into next week, a shift in the pattern, southerly winds delivering some warmer conditions across the uk. so, for this weekend, it will be chilly, particularly at first. some cold and frosty nights, often dry, just a few showers. next week, it will feel warm, where we get some sunshine, but it won't be sunny all the time. there will also be some outbreaks of rain. talking of rain, we saw some heavy downpours across southern england and the channel islands during this morning. that clearing away, then some sunny spells, but also, as you can see from the radar picture, lots of showers, some thunderstorms, some wintry showers, especially

across northern areas. now, most of those showers will slowly fade, as we head through the night. clear skies overhead. that will allow for quite a widespread frost, temperatures even, in the towns and cities, down around or below freezing. we could see lows of around “1! out in the countryside and parts of northern england. so into tomorrow, a cold, frosty, but bright and sunny start. through the day, we will see some showers once again, but these most plentiful up towards the north and the east, where it will stay breezy. further south and west, lighter winds, not as many showers, more dry weather and plenty of sunshine. temperatures still a touch below the average for this point in april. seven to 12 degrees. now, as we move through saturday night, this little ridge of high pressure topples its way eastwards again. that will allow it to get cold and frosty, but this frontal system pitching in from the west will start to introduce a little more cloud. so temperatures out west, in belfast and plymouth

for example, may stay above freezing. most places again having a cold start to sunday morning, but a bright start, with plenty of sunshine through the day. as that weather system approaches, we will see more cloud building in from the west. the majority will stay dry. a bit of rain could just splash into parts of northern ireland later on, but the wind is starting to come up from the south, so temperatures will climb just a little, a trend that will continue into next week. if we do get some sunshine, we could see highs of 18, 19, maybe close to 20 degrees, but there will also be some rain at times, especially in the north and west.

can make a difference.

welcome to bbc news, i'm rich preston. our top stories: there's outrage after another atrocity in ukraine — at least 50 people are dead and hundreds more injured in a rocket attack on a train station. as you can see the station, outside it is empty, but this morning it was packed with people. many of them women and children, trying to flee the city to safety. more help is on the way, with countries sending weapons including, for the first time, an air defence system. after hitting the comedian chris rock, the actor will smith is banned from the oscars for ten years. at least 13 people are killed following torrential rains and a landslide in a mining area of north—west colombia. and, he can still pull a crowd, but will he get enough votes?
