diy space battles and hidden figures. did you see that? 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's used a long—range infrared camera to film the arrival of migrants and refugees at camps across europe. it's 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 can't really see their faces. so it kind of anonymises people. it's an image of an individual without biological traits. it dehumanises a person, in a way, which is appropriate since it is weapons grade technology. one interesting result of using a thermal imaging camera is that you can't tell the skin colour of the people in the film. they are simply people. and, of course, that's 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 glow.

we have to welcome 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. germany is one country that has taken on hundreds of thousands of refugees. many travelled to the country from syria after hearing about its open door 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. jane 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 spaces, colourful boxes lining one of the halls. most are from syria but there are asylum seekers from other countries as well. afghanistan. russia. pakistan. ideally, guests only stay here for a few weeks, 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, hall 26 used to house

refugees who have been moved out since the conference started. thejuxtaposition between a refugee camp and a high—tech trade show really struck me. but of course, many refugees have been helped by technology, using internet and smartphones to guide theirjourney to germany. including this man, a programmer from damascus who spent ten days travelling to germany from turkey and was filmed for spiegel tv. he graduated as a computer engineer in 2010 and arrived in germany in 2014. i was a little disappointed because i thought i would find big technical companies and i would directly find a job and work, but it wasn't like that. i needed about ten months to discover a position. maher connected with a school

that takes a few dozen refugees each semester, and teaches coding skills. the school was heavily supported by facebook, who donated space. mark zuckerberg and his wife priscilla visited the students recently. through this, maher developed an app for newcomers. this is for people who speak arabic so they do not suffer like me in the beginning. they can directly access all the information that they need. maher won an award for this work and is entering an entrepreneurship internship for six months. in berlin, finally i found my dream that i can take courses and connect with a lot of companies. i can enter the tech community here in this country. 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 helped to build a wi—fi network here, which was non—existent. this 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. we are not the 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 from aleppo in syria found it difficult to get online when he arrived in berlin, and had a very different experience in his shelter. we have computer rules, we have three computers for 400 people and you need an appointment to go and use one of them. you have to deal with security and if they are in a good mood they will give you an appointment after two days. if not, it will be two weeks. if i want to use the internet, i won't wait two weeks. he joined a group of activists who installed routers across the city which can connect refugee housing to the internet for free. that is where we like to install our networks, at town halls or churches. i went to see one of the installations at the top of a church tower.

the nodes are routed through virtual private servers which gets around some of the liability laws. this is a nano station antenna, regular five gigahertz wi—fi network like you would have at home. somewhere 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 their language. its campus in berlin comes complete with an autonomous bus. it's also home to a familiar face. we first saw assem hasna last year when we were filming in a camp injordan. he had lost his leg in an explosion in syria.

he was volunteering injordan with a start—up refugee app to print 3d replacement parts. he made the difficult decision to travel to berlin. he is now in cisco, training to be an engineer. it was amazing for me. this old building from outside, 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's 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 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 near future. never has the issue of how to handle the refugee crisis been more controversial. by opening its borders, germany is at the forefront of this debate. and it is clear 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 discovered seven 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 static cavity resonance. this means you can walk around while powering up, and the purpose—built room has walls, ceiling and a floor made of aluminium, generator outside and a power amplifier, so not quite a simple diy job. and finally, researchers at brigham young university have shown off an origami—inspired lightweight bullet—proof shield. the barrier is made up of 12 layers of bullet—proof kevlar and weighs only 55lbs. 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 it right down so you can really feast on... uh... my face. so, a persistence of vision display is predicated upon the persistence of vision phenomenon which is an effect in the human eye and it is 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 breaks it up into vertical columns of pixel data. this single column of light brings out each eye, until it gets to the end of the image and 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 of painted pictures or text in the air for a couple of decades now, but this 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 display massively. with leds, it becomes challenging to create a display than three metres tall, but with our eco technology, we can

create displays up to 200 metres tall, turning skyscrapers into the world's biggest image machines. 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. entschuldigung. 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. it isn't going to be for every location. i wouldn't want to introduce this 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 are going to have to travel a similar path. that's not the only eye—catching projection that 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 mobile devices. it's the latest version of sony's xperia projector, an android—based device that throws a touch sensitive display on a table or wall. it has all the touchscreen functionality of a tablet, with your finger‘s decisions 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're 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 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 box office and has been nominated for an oscar in visual effects. edwards worked with the team at industrial light and magic to recreate that galaxy far, far away and as we found out when we visited them in london, they provided some very cool kit to facilitate his unique directing style. he is a very hands—on filmmaker. he likes to walk around the sets and physically pick up the cameras and walk around and find

interesting angles that might not have occurred to him when he was planning the shoots in preproduction. 0ur visual effects supervisor was keen to be able to apply that same style of film into the synthetic camera, so we used the real—time virtual reality system and so he could show us rather than explain it to us. this is it? this is what we call our v camera. it is an ipad with a controller stuck on the back! so you're using existing technology? we can set it up relatively easily. is this where he did the scenes? this is where he shot his virtualfilm. so this is the scene that was actually set up for the trailer, the first trailer. you would have this scene running and he would just walk around and decide on his best angles

and after that you would tidy up the take that he wanted? the idea wasn't that he would be getting perfectly smooth 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. then it could be immediately picked up by animators. we shot this in london and then pushed it into the pipeline and a tape was ready for him to review the next morning. may i have a go? absolutely. so the animation in this scene is the dish of the death star. 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? waiting for an answer. look at that!

it's the dish going to the death star. here we are following an x—wing as it approaches the shield gate. we can move around and follow it in. this film is set mere minutes before the very first one, and so getting these computer generated models to look exactly like the physical models from 1977 was, i guess, vital? our friends and colleagues in san francisco took digital scans of the original models. they had lots of textural references and faithfullyjust recreated them so that there wouldn't be any jarring differences between these

ships and the others in a 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 have a fantastic team of animators and a team who take all of the renders that we generate and put it all together with all the footage and integrate it into a photorealistic result. so this model here ofjedda, is that completely full detail, so you can move the cameras anywhere? we had a camera rotated around on its own and we moved it randomly around the city. we ended up with hundreds of views. so many of them were fascinating. typically, if you give a shot

to layout, you will start dressing everything to the camera. you'll start laying out buildings, and typically with lighting you will start with backlighting from one direction. but what we found was that because none of those considerations had been taken, you end up with occasionally finding views that were so natural, so lighting would be illuminating one half of the wall, in the background for example, or none of the roads are perpendicular to the camera. that was really successful and we ended up using a lot of those views as the background in our shoots. how much of that was based on a real mushroom cloud? a lot. we did spend a lot of time watching old footage of nuclear explosions. it is quite terrifying when you watch them over and over again. you're rebels, aren't you?

save the rebellion! save the dream. and we wish everyone who worked on rogue 0ne all of the 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 bring 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 motion footage. 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! the fifth named storm of the season

the labour leader, jeremy corbyn, has called on his party to unite and "fight back" to make life better for "the many, not the few", reiterating he would lead the party into the next election following a disappointing by—election defeat in copeland. i've been elected twice to lead this party. i'm very proud and very honoured to lead this party. all my energy is going into leading this party. all our party members' energy is going towards campaigning for this party. britain faces a "sustained and serious" level of terror threat from islamist extremists. that's according to the independent reviewer of terrorism laws. sir mo farah has said that he is a clean athlete, after a leaked report by the us anti—doping agency suggested that his coach alberto salazar may have broken drugs rules. in a further sign of worsening relations between donald trump and the media, the us president has announced he won't attend
