for the prime suspect in the truck attack on a christmas market in berlin. german officials say anis amri, a 24—year—old tunisian already known to the security services, may be armed and dangerous. a six figure reward is on offer for his capture. amri's identity card was found in the cab of the truck that was driven into the market, killing twelve people. german officials say he had been refused asylum and monitored by security services, because of his links to islamist networks, but they couldn't deport him because his documents were missing. hundreds of rebel fighters and civilians, have resumed their evacuation from eastern aleppo. a convoy of buses has now left the rebel held areas, and aid groups say the last hospital patients have now left. now on bbc news, it's time for click. this week — eye robot. robo chef. and some loud, noisy animals meet the locals.

shouting the design museum in london has moved into a new home, and it's suitably stunning. i have come to see fear and love, an exhibition of 11 designers‘ reactions to our increasingly complex world. the most animated star on show has to be an industrial robot arm, which its owner hopes will present a more friendly face to robotics,

and even maybe help us empathise with mechanoids of the future. it senses where you are and comes bounding over to see you, but if it gets bored, it will turn its attention to someone else. it is a bit like an excitable puppy, actually. who knows, installations like this may help to allay our fears of being around giant machines like this. i have to say, it will still be a while before i trust this thing with a scalpel, though, for example. that said, computers are increasingly being used in healthcare around the world. there is plenty of research into how artificial intelligence can help doctors to better look after patients. jen has been taking a look at some of the latest developments. around the world, hospitals are facing a backlog of patients, ageing populations and a shortage of specialist staff. some hospitals are teaming up with artificial intelligence research teams to see if there are ways that high—tech solutions can supplement or even enhance healthcare in the face of these challenges.

singapore has a nursing crisis. its health minister says they will need more than 30,000 new nurses before 2020, and completely rethink the way it cares for its ageing population. so when the ceo of one of its largest private hospital networks approached ibm's watson team, they came up with a pilot project to try to help nurses working with the most critically ill patients. this is the intensive care unit at mount elizabeth novena hospital. it's where four beds are conducted to ibm's artificially intelligent nursing system. collecting all the vital signs from the patients in the beds, it gives the nurses a more complete picture of who needs the most care. in one of the first trials of its kind in the world, the ai is constantly monitoring output and making connections on a vast range of data, including a commonly used scale. higher scores correspond to a higher incidence of death, and it is particularly important in the first 2a hours after admission.

this patient has four alarms, so if you don't see anything flashing here, it means it has been acknowledged already. one of the patients in the ward is at the high end of the alert, and nurses can quickly access the information in real—time and look at patterns in their vital signs to see if they are at greater risk of infections, like sepsis. here in the uk, it's the help ai could provide in imaging which is the focus of research between the nhs and google‘s deepmind. the uk's royal college of radiologists says 99% of hospitals are struggling to keep up with demand, and the uk has the third lowest numbers of specialists who can interpret scans in europe — seven per 100,000 people. the large amount of data is overwhelming a health service that is stretched to the limit.

if you can use algorithms or machine learning or artificial intelligence to set an alert for you, to trigger to say something has happened, you need to go and see this, this is urgent and you need to deal with it, in the next hour or so when you may have not known about that. i think it will improve quality of care and actually improve equity across the system. one of the first areas where the nhs is testing artificial intelligence is at moorfields, one of the busiest eye hospitals in the world. deepmind is applying the same machine learning technology behind its winning alphago computer programme. it beat the world's best human player by computing tens of thousands of positions per second. we started deepmind to develop general—purpose learning algorithms and use those tools and systems to make the world a better place. it was obvious to us a few years ago that there is a massive opportunity to deliver really meaningful and proved benefits to many patients and people across the world using our sort of techniques to try to improve the way

we diagnose and treat patients at risk of all sorts of diseases. the moorfields hospital research is using scans from this 0ct, or optical coherence tomography machine, which creates a 3—dimensional retinal image. it is used to diagnose diseases like age—related macular degeneration, and diabetic retinopathy, two leading causes of sight loss. deepmind is trying to develop a computer algorithm which will identify scans of concern. 0ct scans were chosen because of the high rate of information included in them and the way they can be broken down into pixels showing areas where damage has occurred. i was particularly attracted to speaking to deepmind because i thought their algorithms would have the best ability to deal with 3—d imaging of an extremely high resolution form, such as with 0ct. this is such a delicate area of the eye that any sort of disruption of the normal architecture has really amazingly severe visual consequences. so i believe health care could be at a pivotal moment in history

where these advances in technology, such as artificial intelligence, will fundamentally change the way medicine is practised, and have huge benefits for patients. if you think about it, the best humans in the world will have seen only a fraction of the number of cases that we can show to an algorithm. imagine that we took all of the cases that many of the top ophthalmologists in the world have seen themselves, and aggregate them all in one place. now our algorithm can sample from all of the case studies that our various different humans have seen, and try to deliver a much higher standard, more consistently, when making a diagnosis. all these projects are still in the research or pilot stage, but it's fascinating to see how artificial intelligence could transform healthca re and perhaps lead to faster and better treatment in the future. hello, and welcome

to the week in tech. it was the week that amazon completed its first drone delivery in cambridge. taking 30 minutes from order to delivery, plus three years if you factor in research and development, the elaborately orchestrated trial involved an amazon product and a bag of popcorn. it was also the week that super mario came to the iphone, pokemon go got an upgrade, and a uk surgeon filmed a hernia repair operation using snapchat spectacles. probably not one for the squeamish. and mere hours after hitting the road in san francisco, uber has been ordered to stop offering passengers self—driving cars. regulators have warned the company required a state permit or will face legal action. the order comes after footage emerged of a self—driving car apparently running a red light.

and finally, stanford students put teeny goggles on tiny parrots. newsworthy enough, you might think. but this was to protect the birds‘ eyes as they were trained to fly through laser beams. the new technique has allowed scientists to gain a greater understanding of how birds fly by analysing the movement of particles around their flight paths. it is hoped the work will improve flying robots of the future. music plays whether you love or loathe cooking, sometimes it would be nice tojust make it a little bit quicker and easier. so i have been testing some of the latest gadgets that aim to come to the rescue. i have called in a bit of help from a friend. meet moley. this prototype robotic kitchen is making crab bisque today.

it learnt these slick moves from a professional chef, whose motions were tracked in the same space, making the same dish, using sensors and cameras. this is actually quite extraordinary to watch, and that is the first drip of mess that i have seen. it seems to be pretty clean and tidy. the only issue is it doesn't actually do the washing up. moley, iam not doing it! and no drinking that. everything needs to be precisely prepared before, although some form of ingredient recognition is claimed to be within its abilities before it goes on sale, which as you might imagine, is going to be at quite a cost. a figure of around £100,000 is being thrown around. while moley gets on with things, i will use my devices to make all of this, and there is nobody to do the chopping for me, so i'd better get on. first up, the anova sous vide precision cooker to make some miso salmon.

for anyone who doesn't know what this method is, like me a few weeks ago, it involves sealing food in a bag and cooking it in water at a precise temperature for a specific amount of time, so it should end up perfectly and evenly cooked all the way through. this device connects to a smartphone app, where you will find recipes and the instructions you need. once you have prepared the food — and that is the salmon in the bag, quite literally — you pop it in any suitably sized pot with the anova attached, and confirm you're ready to go. or with this particular model, which is wi—fi enabled, you can even set it remotely, although you would need to have everything prepared, of course. so that is the main bit of the cooking done. but it does still need searing for one minute in a frying pan. this needs to cook forjust one minute on each side, so i might put the heat up while it does that. ok, so now for the moment of truth.

the flavour is great. it definitely feels evenly cooked throughout. i think personally, i probably missed the fact it is not a little bit crispier from the pan. i could have left it in the pan to do that, but i followed the instructions, which is why i didn't. but the taste is fantastic, and the flavour is really good. a smart frying pan could have dealt with that issue. and funnily enough, that's just what pa ntelligent is. ok, i thought the idea was pretty dark to start with. who needs a bluetooth—connected frying pan that connects to your mobile to tell you how long to cook things for? i do, it seems, as i've perfected some dishes that may otherwise been compromised. this is great. it even tells you how many degrees lower it needs to be. love that graph at the top. the pan‘s temperature sensor keeps track of the heat, so you're regularly reminded to turn it up or down. and based on timing, you're also told when to stir and when to add other ingredients. that is really, really good.

i was concerned the potato wouldn't be cooked all the way through, and i think if i had done this myself without the smart frying pan, that would have been a risk. but that was fantastic. spot—on, i'd say. back to moley, and the soup seems to be almost ready. this was the only dish it had on offerfor us today, but eventually it should be able to learn as many recipes as it gets taught. wow. a great bit of theatre, but i am very irritated by this mark on the bowl. the only is there is nothing to clean it up with. and the soup needs trying. but i don't eat crab, which is an issue. talia? i am giving it a go. 0oh, crab. it's really nice. i'll be a while. that was lara, and what about that moley robotic kitchen? meanwhile, back here at the design museum in london, some of the most beautiful 3d printing i think i've ever seen.

these are one artist's suggestion about how we might revive the ancient culture of making death masks. i wouldn't mind one because it would make me look like i was in the film alien. next, we're going to ask — what would happen if you scaled that technology right up? what if you were to let it loose on our homes, our cities and our architecture? the buildings around us don't look the way they do by accident. the design, the shape and the structure are all the result of the mix between the desire of designers, what we need the buildings to do and the practical limitations of the materials and building techniques we've discovered. this is very much the age of concrete, steel and glass. but with new technology and techniques, what could the next wave for our buildings look like?

the building industry is still in 19th century technology. it hasn't really evolved like other disciplines and if you look now at the speed at which cities are growing, so many people are moving to the cities, but our technology is really lacking behind. industrial scale 3d printing has already been put to use to print full—scale buildings, like this housing project in china. but researchers are now turning to computers to notjust create buildings but to help design them. and the results? well, they're a little unusual. this is a prototype column that's been 3d printed here at the school of architecture at the university college london. we basically use a computer and use algorithms to generate these forms for us. they may look very alien and strange, but actually they're highly optimised. so these forms attempt to save material and become more efficient, but at the same time they produce a sort of aesthetic that is very appealing to us

as architects and that really doesn't look what a normal building any more. normal 3d printing creates objects by building up thousands of very thin layers, which you can imagine takes a fair while. the idea here, though, is to save time by printing just what you need, which means rather than printing flat layers, instead built with shapes, like pyramids. the software they've created can take this a step further, by figuring out which bits are structurally essential and then getting rid of the rest. before computers we had to build by hand, right? and now we can create algorithms that make these calculations for us, but that doesn't mean that we don't design, we just optimise the process more and we can create things that we couldn't ever think of before. 3d printing will allow architecture to be much more detailed, much more fine, and also much more efficient. like, if you can 3d print exactly the material that you need in a specific part of the building, it will make it perform much more efficiently.

before these new techniques can be put to use, they first need to be proven to be strong and safe. case in point, this mx3d bridge project aims to 3d print a usable steel bridge right in the centre of amsterdam. created using similar generative algorithms, the project has been held up while the company proves to regulators that the design is structurally sound. the actual bridge now isn't slated to appear until next year. techniques like these certainly promise to spice up our city's skylines, but it could still be a while before we see 3d printers on our building sites. that was steve. now, earlier this year we shot an entire programme in 360 degrees. to get these shots, we had to use a six gopro cameras strapped together and, let me tell you, the postproduction was a nightmare. but since march, more than a dozen

much cheaper consumer targeted 360 cameras have gone on sale, so we felt we wanted to see if they were any good. so we sent our top team on a mission. go to central africa, see if the cams can cope and, above all, keep calm! it almost went to plan. screaming. we're driving through rwanda. producer menaz has come to help me shoot some of the highlights of this landlocked country in 360, including a beach. we're close to the border with congo, at lake kivu, rwanda's very own riviera.

well, i found my way to the beach and i'm going to try this first of all. it's the insta360. the insta has two 180 cameras that gets stitched together on the device. you strap it on your smartphone and the app fires up. it's almost too easy to use and superquick. we're actually not here to shoot the beach, we're here to capture something quite special. meet some of this acrobatic squad who've taken an interest in my new camera. so, i'm not sure this is a good idea. the insta360 stitches the two 180 shots together really well, with a few aberrations, or ghosting, near the edges of each lens. there is no post, so as soon as it's shot you can watch it back or share it from your phone. time to try something different. right, we're leaving the beach

and we're on our way to the mountains. it's supposed to be a beautiful journey, so we're going to use this camera, from a number of windows in the car, to try to capture the beauty of the rwandan countryside. dashboard cameras are typically used to record any accidents that might happen, but we made use of this super hd wide angle dash cam as a perfect travel logger, with the bonus that each file has its gps information attached. before we set off, menaz set up another 360 camera just in case we spotted a filming opportunity. the lg 360 cam is the cheapest of the four we've brought with us. two cameras each take a 200 degree shot, which are also stitched together on the fly. all set up, we arrive at the volcano mountains, ready for some unexpected guests. unlike the insta, the lg cam connects wirelessly

to your smartphone, so you can leave it right in the middle of the action and then sit back and watch. we found the picture wasn't as crisp and colourful as the insta360s. the camera is lightweight and the built—in battery didn't last long. but the three microphones, though, offer good surround sound, something you'll appreciate more if you what your movies through a vr headset. as the light faded, we decided to prepare the serious kit that we'd be using to film our trek high up on the mountain early the next morning. i brought the 360fly, which looks like a golf ball with an eye. that eye is a 4k camera, with a single 240 degree superwide lens. that means there's no stitching together of shots, and that should mean a smoother, cleaner picture. menaz opted for kodak's double action cam set up. the two cameras need to be

synchronised, so they are started by a remote—controlled watch, so they record at the same time. the image from the two cameras needs to be stitched together later with kodak software. if the stitching works well, two 4k cameras should deliver winning results. we've been told rwanda's parc des volca ns was stunning, so we decided to trek 3,000 metres up to take a look. 0ur fellow adventurer carl kindly agreed to be our cameraman, which means we strapped the golf ball to his head. and it soon became apparent what the limitation of my single lens camera was. a great, mucky, black pit at the bottom of the picture. whilst this usefully masked out carl, once in thejungle it just looked awful. to be fair, it can be cropped out later in post,

leaving a better view that's actually 360 horizontally, but you can't look down. the superwide angle made everything seem far away. anything close up looked great, but the sound quality was woolly. as we trudged through the undergrowth, menaz decided it was time to swap over to the kodak. it was then the adventure really took off. as the air got thinner, this camera looked like it would capture anything we came across. 0r anything that came across us. by having two super high—def cameras, we weren'tjust able to capture these incredible creatures wherever they went, but we had the resolution to zoom in too. 0n the downside, the two cameras didn't automatically stitch well together.

after fiddling with it using kodak's own software, we decided one shot was running behind the other. after a calculated tweak, we got these much better results. the picture quality was the best of the bunch. the consumer 360 cameras can allow you to capture everything in one go, but finer details still elude even the best of them, meaning it'll still be a while before you feel like you're right there. that was dan simmons, clearly angling to be the 360 david attenborough. that's it from the design museum, in london. next week, it's the click christmas party, so be prepared for, well, anything! plus, a look back at our best bits of 2016. in the meantime, we live on twitter. thanks for watching, see you soon! hello there.

well, the run—up to christmas is looking unsettled, as you have probably heard. spells of wet and very windy weather on the cards, certainly very windy weather across the north of the uk. and it is going to be very windy overnight across scotland and northern ireland. frequent showers here, particularly for scotland, with some snow over the higher ground. a few showers across western britain as well, but i think for the midlands, the south and the east, it should stay dry. quite chilly, though, with temperatures not far off freezing by the end of the night, and mist and fog forming, too. but across the north it will remain very windy. some icy patches to watch out for as well. these showers will be wintry, snow on the high ground,

maybe down to lower levels as well. there will be plenty of showers across northern ireland, some of these moving across the irish sea into north—west england, for wales, and into south—western england as well. now, for the midlands eastwards, though, it is a dry start, really chilly, but at least it will be bright through the morning, with some sunshine around. but watch out for the mist and fog across the south—east corner. some of it could be quite dense. but i don't think it will last that long, because the breeze will continue to pick up all the while, so that should clear. showers, though, will continue to move eastwards, but i think many southern and eastern areas should remain dry. and those showers becoming fewer as we head on towards the afternoon. but frequent across the north, further heavy ones, with hail and thunder mixed in, some snow to the high ground, feeling really cold and raw because of the strong wind. and then itjust gets worse as we head on in towards friday. met office amber "be prepared" warnings are being issued for the second named storm of the season. storm barbara will impact the united kingdom as we head on in towards friday. it will bring all of us a spell of rain, very windy for us all. but it is the north of the uk,

closer to the storm centre, which will be battered by exceptionally strong winds. now, we are looking at gusts up to 90 miles an hour across the north mainland of scotland, to the northern isles, 80 mph for the western isles, 70 mph for northern ireland and 60 mph, potentially, for northern wales and north—west england. so this is likely to be very disruptive. keep tuned to the weather forecast. as we head through christmas eve, it remains very windy indeed. best of the weather across the south, will be fairly mild, with some sunshine, but we will still see gales and showers across the north, with a wintry mix over the high ground. for christmas day, we are also looking at some very windy weather, particularly across the north, with a spell of rain which will spread right across the uk. another pretty deep low moving through to bring us those strong winds, and also that spell of rain. but it will be exceptionally mild across the south. in fact, we could see record—breaking mild temperatures across the south—east. a very warm welcome to bbc news, broadcasting to our viewers in north america and around the globe.

my name's mike embley. our top stories: a europe—wide manhunt is under way for anis amri, the prime suspect in the truck attack on a berlin christmas market. german officials say the 24—year—old tunisian may be armed, and they've offered a six—figure reward for information leading to his arrest. a convoy of syrian buses leaves rebel held areas, as the evacuation of people from eastern aleppo makes fresh progress. the russian president orders tighter restrictions on alcohol after 65 deaths from toxic bath lotion.
