my name's mike embley. the british government's brexit bill has suffered its first defeat after the house of lords said ministers should guarantee eu nationals' right to stay in the uk after the split. however, it is merely a setback as mps will be able remove the lords' changes when the bill returns to the house of commons. a us congressional committee has agreed to investigate russia's alleged interference in last year's us elections. the house intelligence panel inquiry will scrutinise contacts between donald trump's presidential campaign and moscow. the white house denies any improper behaviour during the election campaign. syrian government soldiers have entered the ancient city of palmyra three months after the so—called islamic state re—ca ptu red it from them. now on bbc news, it's time for click. this week — new homes and new lives. diy space battles

and hidden figures. did you see that? eu, shame on you! chanting: eu, shame on you! we are living in interesting times. to many, it feels like the world is shifting on its axis. tempers are rising, voices are being raised. and there is movement — political, ideological, and physical. and this is one of the most

divisive issues of the day — how to handle what the un has called "the largest migration of people since the second world war." are they migrants? are they refugees? should they be welcomed? should they be turned away? at the barbican in london, artist richard moss is making his view clear with this work, incoming. he has used a long—range infrared camera to film the arrival of migrants and refugees at camps across europe. it is actually a military tool that can detect body heat from 30 kilometres away. it can see through smoke and haze, day or night. so this is a thermographic camera.

in other words, you can actually see people's bodies glowing. a radiant thermal glow. you cannot really see their faces. it kind of anonymises people. instead of imaging an individual, it images a biological trace. it strips, dehumanises a person, in a way, which is appropriate since it is a weapons grade technology. one interesting result of using a thermal imaging camera, of course, is that you cannot tell the skin colour of the people in the film. they are simply people. and of course, that is part of moss's point. he says he wants to use the technology against itself, showing that the same cameras that allow missiles to see can also emphasise the fact that all human life gives off the same bright glow. we have to work with

these people as humans. instead our governments have created these extraordinary technologies to enforce those borders. so i guess i wish people would dwell on that a little bit, meditate on that. germany is one country that has taken on hundreds of thousands of refugees. many travelled to the country from syria after hearing about its opendoor policy in the summer of 2015. but successfully integrating asylum seekers into society here is still one of the main challenges facing the nation. there are many obstacles to integration, including finding housing and getting a job and learning the language. but technology may help to speed the process. jen copestake has been to berlin, which is now home to over 60,000 syrian refugees, to see how. when the refugee crisis began,

some of germany's largest empty buildings were given over to house refugees, including the international congress centre. it was abandoned for conferences, and is still home to over a50 guests. eight people live together in each of these living spaces, colourful boxes lining the main halls. most are from syria, but there are asylum seekers from other countries as well. i'm from afghanistan. pakistan. belorussia. afghanistan. ideally, guests only stay here for a few weeks or months, but many people have lived here for over a year. i first heard about this camp when i was covering europe's biggest tech show. i was surprised to learn that there had been people living in the halls here as well, even recently. in fact this hall, 26, used to house refugees who have moved out since the conference started. thejuxtaposition between a refugee

camp and a high—tech trade show really struck me. but many refugees have been helped by technology, using internet and smartphones to guide theirjourney to germany. including maher ismaail, an android programmerfrom damascus who spent ten days travelling to germany from turkey and was filmed for spiegel tv. crossing the border. he graduated as a computer engineering 2010 and arrived germany in 2014. i was a little disappointed because i thought i would find big technical companies, and i will directly find a job and work, but it was not like that. i needed about ten months to discover courses. this school takes a few dozen refugees each semester, and teaches them coding skills. the school was heavily supported

by facebook who donated space. mark zuckerberg and his wife priscilla visited the students recently. through this place, an app called dalili was developed to provide information about berlin to newcomers. it means ‘my guide‘ in arabic, so they do not suffer like me in the beginning. they can directly access all the information that they need. he has won an award for his work and is entering an entrepreneurship internship for six months. in berlin, finally i found my dream that i can take programming courses and connect with a lot of companies. i can enter the tech community here in this country. but it was not easy to find that in the beginning. for many newcomers, the legal requirement to learn german is one

of the hardest hurdles to integration. outside the class, students can use one of these 90 chromebooks donated by google. felix tietze helped to build a wi—fi network here, which was non—existent. this part is the server, a little server. it controls who is allowed to get on the internet and who is not allowed. the chromebooks are allowed to be taken out five evenings a week, and are controlled by a password which changes hourly. if anybody does something wrong, we can tell the government that we are not bad people. this guy was a bad person. this distinction is important in germany, where regulation makes

the owner of a wi—fi network liable for any activity. mohammed mossli, from aleppo in syria, found it difficult to get online when he arrived in berlin and had a very different experience in this shelter. we have computer rules, we have three computers for 400 people and you needed an appointment to go and use one of them. you have to deal with security — if they are in a good mood, you will get an appointment within two days, and if they are not in a good mood they will give you an appointment as after two weeks. like, if i want to use the internet, i can't. he joined a group of activists called freifunk who installed routers across the cities which can connect refugee housing to the internet for free. that is where we like to install our networks, in townhalls or churches. i went to see one of the installations on top of a church tower. the nodes in the mesh network are routed through virtual private

networks which gets around some of the laws. this is a nano station antenna, regular five gigahertz wi—fi network like you would have at home. it can reach... a location like this where there are no inhibiting factors, this can reach for several kilometres. cisco, one of the world's largest network providers, saw an opportunity where if refugees had online access, they could connect to courses already available in multiple languages. its high—tech campus in berlin comes complete with an autonomous bus. it is also home to a familiar face. we first saw assem hasna last year when we were filming in a camp injordan. he had lost this leg in an explosion in syria. he was volunteering injordan with a start—up refugee openware to 3—d print cheap synthetic parts. it was impossible to get a work

permit, so he made the difficult decision to travel to berlin. he is now in cisco training to be an engineer in the internet of things department. it was amazing for me. this building from outside, so old and on the inside it is filled with cutting—edge technology. when i realised that this would be my workspace i was even more excited. he spends his weekends teaching a robotics course for children. it is a nice and fun way to introduce programming to children. cisco is currently working with five refugee interns and would like to expand the programme. they see the influx of syrians as an opportunity to fill the demand for programming skills in the country. where would you see assem after this programme? i would love to hire him in the innovation centre,

because at the moment i have a lot of different topics that i want to establish and i would love him to engage with our customers and the solutions. even in the nearfuture. never has an issue of how to handle a refugee crisis been more controversial. by opening its borders, germany is at the forefront of this debate. and it is clear from what we say in berlin that the tech community has a role to play and can help ease the transition to a new home for many. hello and welcome to the week in tech. it was the week that uber found itself under fire after a former employee accused the company of sexual harassment in a blog post. uber responded, saying it would conduct an urgent investigation into the claims, which it called abhorrent and against everything uber stands for and believes in. it was also the week that youtube announced it would get rid of unskippable ads in 2018. scientists at mit showed off

a special coating making it easier to get ketchup out of a bottle. and astronomers have detected seven ea rth—sized planets orbiting a single star. and, before you ask, three of them may have conditions to support life. if you just hate living in a world with wires, then disney research may have the answer. their prototype living room can wirelessly charge ten items, such as smartphones and fans, by quasistatic cavity resonance. this means that while you can walk around while powering up, the purpose—built room has walls, ceiling and a floor made of aluminium, with a copper pipe in the middle, a signal generator outside and a power amplifier — so not quite a simple dionb. and finally, researchers at brigham young university have shown off an origami—inspired light weight bullet—proof shield. the barrier is made up of 12 layers of bullet—proof kevlar and weighs only 55 pounds. how many faces can you see in this picture?

did you see that? this is a persistence of vision display. you can only see it when your eyes, or in our case the camera, move left or right. we've slowed right down so you can really feast on... ..uh...myface. so, a persistence of vision display is predicated upon the persistence of vision phenomenon, which is an effect in the human eye. and it's the effect where when you look at any bright light and you look away you see a ghost of that bright light for a moment. so what happens is our display takes a standard two—dimensional image and it breaks it up into vertical columns of pixel data. this single vertical line of light blinks out each column sequentially,

so column one, two, three, until it gets to the end of the image and then starts over. so as your eye looks away from the display, it prints each column in your retina in a different location and the whole image is reassembled in your eye. moving strips of super fast flashing leds have painted pictures or text in the air for a couple of decades now, but lightvert relies on our eyes to do the moving instead. something they are naturally doing all the time. for what purpose? well, enormous adverts, for a start. we've created a new type of projection technique for creating persistence of vision displays and we patented that globally and what that lets us do is scale up the size of the display massively. so, with leds and other light sources, it becomes challenging to create a display that's more than say three metres tall. but with our echo technology we can create a display that's up to 300 metres tall, effectively turning entire skyscrapers into the world's biggest image machines.

and that's why if you've been walking down a particular street in berlin last monday, you might have seen my face out of the corner of your eye. do you think this is safe? do you think this is too distracting for drivers, for example? it's very important that we introduce it in the right way and it's not going to be for every location. i certainly wouldn't want to introduce this medium next to a motorway. we need people to understand it and, much like when led billboards first came into the public realm, they were very distracting and there was legislation instantly put in place in order to prevent distraction from drivers. we're going to have to travel a similar path. and that's not the only eye—catching projection i've seen this week. ahead of next week's mobile world congress in barcelona, i've also managed to get a sneak preview of the future of mobile devices. kind of.

it's the latest version of sony's xperia projector. it's an android—based device that throws a touch sensitive display onto a table or a wall. it has all the touchscreen functionality of a tablet, including pinch and zoom, with your finger‘s positions being watched by a camera under the projector and a row of infrared sensors at table level to detect when you've actually touched the surface. we are heading towards a world where our devices will be so small that we won't want a screen or a keyboard or any kind of input device attached to them and i see this as one of the solutions. you just have a display when you want it, on whatever surface is around. so, very cool, but this week... ..even that is not the coolest thing i've seen. from blue screen jungles to strange adventures in time,

over the past few weeks we've been exploring some of the best visual effects from the past year and this week is no exception. directed by gareth edwards, the visual genius behind monsters and godzilla, rogue one has earned over $1 billion at the worldwide box office and has, unsurprisingly, been nominated for an oscar in visual effects. edwards worked with the team at industrial lights and magic to recreate that galaxy far, far away and, as we found out when we visited their london office, they provided some very cool kit to help facilitate his unique directing style. so he's a very hands—on filmmaker. he likes to walk around his sets and physically pick up the camera himself and walk around and find interesting angles that might not have occurred to him when he was planning out

the shoots in preproduction. our vision effects supervisor was keen that he could apply the same style of filming to the synthetic cameras, so we used a real—time virtual reality system, and therefore he can show us rather than explain to us. and this is it? this is it. this is what we call our vcam renderer. can ijust point out, it's an ipad with a vive controller stuck on the back! so you're using existing technology? exactly. and we can set it up relatively easily and quickly. and is this where he did these scenes, in this room? this is where he shot his virtual camera work. so this is a scene that was actually set up for a trailer, the first trailer, that we did for rogue 0ne. you have this scene running and he would just walk around and decide on his best angles and then after that you would tidy up the take that he wanted? the idea wasn't that he would be getting perfectly smooth,

composed camera moves, but he was able to sort of show to us, the beginning of the shot, i want it here, the end of the shot, i want it here. we could then publish this through our pipeline software, and then it could be immediately picked up by animators and lighting tds. we shot this with gareth in london, we then pushed it into our pipeline, it was then picked up by people in san francisco and the take was ready for him to review the next morning. may i have a go? absolutely. sojust...yeah. so the animation in this scene is the dish of the death star. oh, look, you can see behind the dish! so i can get a different shot to gareth if i wanted? if i find a better shot, do i get a job? laughs waiting for an answer... laughs look at that! it's the dish going

to the death star. so, here, we're following x—wing as it makes its approach run towards the shield gate. we can just move around and frame up on camera moves and follow the ship in, move in front of the ship. this film is set near minutes before the very first film, and so getting these computer generated models to look exactly like the physical models from 1977 was, i guess, vital, wasn't it? our friends and colleagues in san francisco took digital scans of the original models from the art department, and they had lots of texture references, and thankfully just recreated them so that there wouldn't be any jarring differences between these ships and the ships in new hope. we have teams of people who are responsible for laying out camera moves, we have teams

of people who are building digital models, texturing digital models. we've got a fantastic team of animators and then we've got a great team of compositors, who take all of the renders that we generate and put it all together with the footage and integrate it into hopefully photorealistic results. so this model here, ofjedha, is that completely full detail, so you can move the camera to anywhere? we had a camera that rotated around on its own axis and we moved it randomly around the city and ended up with hundreds of views. so many of them were just fascinating in what they ended up finding. because typically, if you're given a shot to lay out,

you'll start dressing everything to the camera. so you'll start laying out buildings that stack away from the camera and, typically with lighting, you would start with back lighting at three quarters, from one direction. but what we found was that, because none of those considerations have been taken, you just end up with occasionally finding views that are so natural, so the lighting mightjust be illuminating one half of a wall in the background, for example, or none of the roads are perpendicular to the camera and they're all going off at weird angles. so that was really successful and we ended up using a lot of those views as the background in a lot of our blue screen shoots. how much of that was based on real mushroom clouds? a lot, actually. we did spend a lot of time watching old footage of nuclear explosions. which is kind of terrifying, when you're watching them over and over again, daily. you're all rebels, aren't you?

save the dream! and we wish everyone who worked on rogue 0ne all the very best of luck for the oscars this weekend. just a quick word about next week's programme, which will be at the mobile world congress, the big phone show in barcelona. we'll be bringing you the full view from the show, mainly because we'll be repeating what we did in switzerland last year and filming it in 360, although this time we'll be streaming some of it live and we'll show you how we filmed this incredible super slow—mo footage. and i'll give you a clue, the device is very, very mobile! in fact, we'll show you exactly what it is and how good it is online on monday. keep your eye on twitter for more details! well, a very blustery night out

there for some of us, particularly across southern parts of the uk, especially the south—west, around the bristol channel. breezy inland too. and really, the weather is going to be very unsettled over the next few days. lots of clouds, lots of weather fronts out there in the atlantic, ready to come our way. this is what we've got through the early hours. here are the winds, quite strong in the south. some rain and hill snow across more central parts of the uk. and then we've got temperatures near freezing across the north, with some showers as well.

now, the good news is that the winds will ease, eventually, through the course of the morning. it will still stay relatively breezy, and you can see there's a bit of cloud and rain again across parts of the midlands wales and the north—west in the morning. but i think by lunchtime, most of the uk should be enjoying fine weather. so this is a snapshot of thursday at 3pm in the afternoon. predominantly sunny, really a very pleasant day, quite breezy, though, still, especially across that south—eastern portion of the uk. some nice weather through yorkshire, not so bad in the north—west. but then, eventually, into northern ireland and scotland, we run into here, and there's quite a few showers around, and it feels on the chilly side as well. and there is a rain on the way for northern ireland. that won't arrive until thursday evening. clearfor a time in the evening across the rest of the country, before more rain. so these are low pressures here spiralling our way. this is the start of a very unsettled period through friday. and that's going to take us right into sunday as well. so rain around on friday, at least for some of us, not necessarily there in scotland. could be even sunny

in the afternoon. and then by the time we get to saturday, that weather front‘s still with us, or at least that area of low pressure is with us, with the cloud and rain spiralling around it. it will be quite breezy as well. wherever they rain occurs, it is going to feel on the chilly side, probably no higher than about six degrees, six or seven degrees, across some of these more northern areas, and barely touching double figures in the south. plymouth, i suspect, around 9. that takes us across saturday into europe then. and what's it looking like across the rest of the continent? actually, quite a bit slow to come across the alps. unsettled for spain. very unsettled, as we have established, across the uk, and also into france as well. so a large chunk of western europe experiencing that very changeable weather on saturday. and into sunday, the same thing continues. you can see lots of fronts here. low pressure across the uk. brolly to hand. but clearly there will be breaks in the weather. it is not pouring all the time.

here is the weather for the weekend if you happen to be thinking about it already. so, wet at times, and the winds will be quite strong, and it will feel on the chilly side. 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: the british government suffers its first defeat over its brexit bill after the house of lord rules eu nationals should be given the right to remain in the uk. in america, a congressional committee says it will investigate allegations russia colluded with the trump presidential campaign during the election. syrian government forces once again enter the ancient city of palmyra months after the so—called islamic state drove them from it. and it's being called the greatest blunder in 0scar history — the pairfound responsible for that envelope mix—up are told they won't be back again. hello.
