hello. this is bbc news. the headlines at half past three: hundres of thousands of people have marched through barcelona in support of spanish unity and against catalonia's unilateral declaration of independence. the international trade minister, mark garnier, faces an investigation — after he admitted asking his secretary to buy sex toys. heathrow airport says it's investigating how details of its security procedures were found lying in the street. scotland's first minister is to apologise on behalf of her government to gay men convicted of sexual offences which have since been abolished. parents will no longer be able to use a legal loophole to avoid paying child maintenance, under new laws to be brought in within months. now on bbc news, it's time for click this week, spotting fake news and debunking the people in power. wandering the ruins. and something wicked this way comes.

going into space has long been the dream of many a sci—fi fan and for one bbc presenter that dream is about to come true. in a world first for the broadcast industry, spencer kelly, who fronts the bbc technology programme click, has been accepted by nasa to visit and report from the international space station. during his stay on board, he'll present several episodes of click. kelly, who says he has always harboured ambitions to leave planet earth, will test how the latest technology performs in zero gravity. he says he's looking forward to the months of training ahead of him.

that's not... that's not true. i'm so sorry. that shouldn't be on the autocue. it's my christmas fantasy list. it's fake news! we are fighting the fake news. it's fake, phoney. fake. the fake media tried to stop... everyone‘s using the term these days. the problem is, it now seems to mean anything from actual lies to something you simply don't agree with. and the tech world is anguishing over how to sort fact from fiction, from opinion, from satire, from highly skewed and misleading headlines. and as a result, fact checking organisations are now working to counter the fake news effect. the first draft coalition operates around the world and in germany it's working alongside journalists from correctiv, agroup to help improve online transparency. in the run—up to the recent election here, they published a daily newsletter, investigating

the most popular stories on social media, suspected of being false or highly misleading. you look at an incident in a video, but then when you're trying to get verification you're looking largely away from the main incident and into the background. is what's being claimed in the captioned description in this video what is actually being seen in the video? one which showed a couple of maybe not traditional northern europeans, a couple of dark skinned guys, waving their passports. this was claimed to be smug immigrants trampling all over german people's feelings. the tweets said they were insulting local germans and provoking them. using simple tools such as reverse image searches to verify the original sources of videos and in this case a facility called ‘watch frame by frame‘, the journalists were able to identify the street name, unter den linden. the thing that helped me is there is a police officer walking through the video, back here.

after locating the police squad in question they were able to get an eyewitness account of what happened, notjust in front of the camera but also behind. actually we discovered that behind the camera there are like 100 people insulting these three to four guys in the first place. they were, if anything, just reacting. another story debunked by the group involved what looked like a number of muslims standing at a bus stop. the headline was: this is how islamic society, or an islamistic society, would look like, so we are heading to this. so we were taking a closer look at this. narrowing down where bus and tram lines met, and cross—checking with street views, the journalists were able to pinpoint the spot and the fact that the group had just come out of a christian church.

they confirmed that they work with refugees and they even know the guys in the video and they were just coming back from a baptism and they were trying to celebrate the baptism and were just heading for lunch. so this was really, really misleading information and trying to manipulate people and to make them worried about — online and there is an ongoing debate about whether the platforms on which the stories are published should be the ones to police them. making sure that quality content and qualityjournalism is on top is a big mission. so that's why we work very closely with fact checking organisations and media organisations

around the world. just a couple of months ago we changed our ads policy around misleading news websites. whoever ends are fighting the rising tide of fake news, one things for certain — ultimately we're going to need an automated fact checking system. back in the uk, a stone's throw away from westminster lies full fact. this is an organisation that first came to the public attention around the time of the eu referendum. these guys have some pretty interesting fact checking tools. in this session of prime minister's questions, the group is verifying claims using a mixture of manual and automated fact checking. one of the automated tools being developed looks at the trends behind a claim such as where and how many times any statement was repeated. another tool, called live, will take text from tv subtitles and check it off in real time

against reliable data bases, such as the office of national statistics. using a combination of ai and machine learning, the algorithm will perform calculations and check facts with primary sources. eventually it could be used in a scenario such as this. there are 10,000 more trainee places available for nurses in the nhs, but the right honourable gentleman... yeah, see, that's not right. that's an ambition for 2020, but it's currently not true. how cool would it be to debunk claims like that on the spot? but the system won't be able to challenge more subtle claims with lots of caveats, such as the statement "the nhs is in crisis". nor will it provide simple yes and no answers. gdp is rising. it's kind of like shazam for facts. nurses are using food banks. the tool that i'm most excited about is the speech to text checking.

so it's when somebody is talking live and it takes you in real time to the primary sources. so if a journalist is in a press conference or if they are interviewing someone, they can see straightaway if there's something that the person in front of them has said is true or false, which is particularly cool. i so want that. i so want that! have you used it in anger yet? i haven't used it in anger quite yet. all right. how ready is it? it's ready now, but it can only do one sentence at a time. do you think public figures will have to change the way they behave? there's no debate that can really happen without eventually hitting on numbers and the point at which you hit numbers it's important that they're correct and not being manipulated. that's the place we are starting from and the world we want to create. right, from fakery of news to fakery of images now. ok, that's not exactly the spin that adobe would like us to put it's just unveiled some pretty nifty tools to do just that and we sent

richard taylor along to take a look. 12,000 creatives under one roof, all geared up to find out what's next from the outfit that literally invented photoshopping. the answer, ai as we've never known it before. take this image of denver, where an entire neighbourhood is expunged in a flash and replaced with something more aesthetically pleasing. instead of just trying to fill in the area with surrounding pixels, the software can now extract meaning from the image and make a smart substitute from its library of 100 million other pictures. a similar principle is at play here. the plaster now intelligently removed as the software can understand the protrusion in the middle of a person's face as a nose. and say you wanted to remove something or someone from a video. right now you could try it frame

by painstaking frame. the chances are the result would look crude. but this demo is real. a research project we may well see in a future version of adobe's products. in this era of fake news, the implications of being able to easily and convincingly fool your audience are, of course, potentially troublesome, but adobe is more interested in the creative potential of ai. we are trying to reimagine the entire creative process so you can create the way you want to. machines can see patterns and possibilities that we may not be able to see immediately. adobe says ai should allow creatives more time for artistic expression and to be creative rather than doing boring and repetitive tasks. they say the entire creative process should be way more efficient and ai could potentially even second—guess our next moves. to illustrate, check out this photoshop prototype which has adobe's ai creative

assistant built in. find some images based on my sketch. and within seconds, others space—based themes appear, based on your very rough sketch of a woman in a spaceship. but you might we thinking is all of this is pretty similar to the ais used by google and apple. we have decades and decades of understanding of how artists actually work in our tools. and when one of the world's best creative artists launches photoshop and they know what a creatively pleasing and aesthetically pleasing image is, we are learning from that. so we're not training on just images of cats or dogs, we're training with the world's best people. i was certainly impressed at how for example the ai could take an image of me and within seconds return matches and then further refine them. the tech also understands 3d, so you don't have to be an artist to easily design and iterate.

few people would argue that ai's fantastic in terms of creating efficiencies in our work flows, but isn't there a danger that an over reliance on our machines instead of amplifying the creative process could eventually end up supplanting it? i actually don't think so. into a sort of procedural left brain mode. i don't think ai takes anything away. i think it ends up being this muse at your elbow. and that's the prevailing view amongst creatives here, keen to embrace the automatic possibilities offered up in an ai world. hello and welcome to the week in tech. it was the week that the hawaiian city of honolulu began fining people $99 for paying too much attention to their smartphone while crossing the road.

microsoft announced it's ceased manufacturing its motion sensing controller, kinect. and japanese company toyota gosei showed off a concept car with the airbags on the outside in tokyo. meanwhile, nissan revealed the artificially created noise its electric cars will emit. us authorities are insisting all hybrid and electric cars amazon now wants to enter its customers' homes when making deliveries. the system's called amazon key. trustworthy types who sign up will make use of a smart lock, which will open their front door, allowing deliveries to be left inside their homes. suspicious souls will be able to view the delivery on their phone via a smart camera that they've left at home. what could possibly go wrong? and creepy or cute? you decide. sony's developed a new winking robot assistant, the xperia hello. the robot communicates with users using endearing gestures. it's hoping the bot‘s cuteness will challenge amazon's echo range.

and finally, researchers at harvard have developed a tiny robot that can swim and fly. the micro robot's flapping wings are used to propel the diminutive droid around when it's underwater. its creators hope one day similar technology can be used in search and rescue robots. this is art in the 21st century. trust me, it is. i'm thinking each colour has a specific sound. the buzzing sound is the electric current that lights the leds and it's being translated into a kind of compositional concert. it's kind of got its own groove to it. i like it. this week i'm wandering the halls of a brand—new installation in the heart of london.

it's called everything at once and if it doesn't actually have everything, it certainly has a lot. it's a mixture of dynamic works like the black pot and static pieces by renowned artists like ai weiwei and anish kapoor. there are also faceless voices describing their near death experiences. hi, my name is sam, and i had a near death experience in hospital and my heart stopped beating. and the centrepiece of the exhibition is even more unsettling. i'm about to be subjected to intensely fast flashing images. now, if you'd rather not see them, then please look away now and come back in a couple of minutes. because i'm about to walk through and on test pattern no 12 by japanese electronic artist ryoji ikeda. the experience is overwhelming. mae? siege ragga ihéifia‘gfif‘afi" z

the video frame rate is so high that the black and white is flickering incredibly fast. i can actually see colours in between the black and white, they're moving so fast, there's greys, i'm starting to see yellow and red, maybe that's just because my eyes are exploding, i don't know. ikeda has taken digital files and broken them down into their native zeros and ones. it's these binary patterns that are then blasted onto the viewer. only it looks like i've arrived after the after party. now, earlier we were looking at attempts to combat fake news and so often these days that means the us elections, russia and the like.

but it's actually a problem all around the world in different ways. david reid has been looking at the particular issues in india. this summer mob violence in the eastern state otharkhand was sparked by a rumour on whatsapp that child abductors were targeting a tribal community. the story wasn't true, but still seven people died in violence. it doesn't take much here for long simmering conflicts to boil over and fake news like this can be just the trigger for it. stories like these are very powerful and can potentially threaten india's often tense communal relations. so much so that now even the police are getting involved in tackling fake news. i visited one of the country's main cyber crime units in hyderabad, the capital of the southern

state of telangana. here cyber cops are worried about the threat to law and order by fake stories with the potential to spark riots. police here investigate false and inflammatory stories, try to get them taken down and then attempt to prosecute those producing them, but much of india's fake news is spread through the mobile communication platform whatsapp. because it's encrypted, for police here it's a wall. it's only a peer—to—peer communication, whatsapp. we don't have much cooperation from whatsapp because they simply give the answer that they don't have any storage facility. and you require date and time stamp to prove the case also, and whatsapp, because it doesn't store anything, the date and time stamp is also not there. something like 200 million people in india use whatsapp. for some, the stories shared on the platform are their only or main source of news. if the police are hitting a road

block with whatsapp‘s end to end encryption, others are trying to neutralise fake stories by debunking them. my guess is it often starts on whatsapp because those who put it on whatsapp know it's difficult to track them down. the people who circulate these videos, they are very well aware that it's a fake video. there's no doubt. videos like this one, purporting to show a woman being killed in india by a muslim mob. it's one of the most grotesque, stomach—churning videos you will see. but the harrowing incident it depicts actually took place in central america. this video was easy to debunk. for a lot of videos what we do is break it up into frames, we use google reverse image search

and the first google result is that of this girl who was burned alive in guatemala. she was accused of being an accomplice in a murder, she got caught in a mob and she died. and yet many who saw the video took its claims to be true. the reason is that in india hundreds of millions are encountering the internet for the first time, and they lack the media literacy to assess if news is actually true. we have more than 400 million mobile internet users. 50% of them are using whatsapp. whatsapp is the main medium for promoting the fake news. but how many people are being duped, or the thing they are forwarding, whether it is true or not and whether it's a forward or not a forward, so they are not equipped to deal with that and this is an epidemic—like situation. and as police and journalists battle

eee eeee eeeeeee eeee eee ef'eeef conflict, many are still prone to manipulation from the lies in their inbox. that was david in india. now, with halloween fast approaching, there are plenty of scary movies around but none of them will be as immersive on the way to see a film, a movie, but not as we know it, in virtual reality. we're going to get run over. car honks i think this is 68a, not your standard cinema. haunted cinema downstairs. there's people down there wearing vr headsets. virtual reality film is super exciting, but right now you can only enjoy it in the comfort

of your own home and it's not a social experience. we want to bring people together so they can enjoy vr with their friends, their family, their partner. where am i sitting? we reserved you a seat. oh, excellent. have we got any popcorn? back we go, up and over... oh, popcorn, excellent. is everyone ready to go? all: yeah! let's do it! showtime! scary suburbia. oh my goodness me! that is it down the drain. i'm pennywise, the dancing clown! just left that scene. look behind you... all scream and laugh

a bit unnerving. i want to go home! the king has appeared in front of me. 0k. we've got a collection of films five to ten minutes each and we're showing them back—to—back in a ao—minute montage. it's not the first vr pop—up and none of the hardware the guys are using is cutting—edge either. but they have created a custom piece of software to link all the movie clips together and play them in sync across all the headsets via bluetooth so people can have that shared cinema experience of being shocked all at the same time. this will sort you out! life is not good. this is going to end well, this is going to end very well. i'm burning alive.

brilliant. with several showings starting at the top of the hour, the headsets need to be taken away for charging. it's all very pop—up. but the chaps hope it'll get another hearts racing so they can open up a permanent vr cinema later next year. is this alljust a novelty, though? this is kind of a nightclub in glasgow. ok, that's horrendous. that's horrendous! woah, ok, that's enough. actually it was quite fun to bring a group of friends together. not that i have any here. you can go out and have a shared experience, another group is coming in right now? right now. 0k. masters of turnaround. we'd better be on our way. that's nick kwek, always up for an experience and regularly needing a lie down after a shoot because of it. that's it from the ruin for this week. don't forget we live on facebook and twitter throughout the week, @bbcclick is where you'll find us. thanks for watching and we will see you soon. ?

this week we will see some pretty big swings in temperatures. at the moment this cold air from the arctic is firmly in place and it is targeting scotland and northern england. in aberdeenshire it was one of the warmest places in the country yesterday, 17 celsius factories westerly winds but the winds of change direction, now in northerly direction and it sought a drop of nine celsius plus 30 mph gusts. anyone there has been plenty of

sunshine out and about. —— in land. the brisk winds extending them the north sea could bring some isolated showers but should keep the frost at bay in coastal areas. in land the clear skies and light winds and low temperatures to plummet, one of the colder makes be done far. the temperatures could get down to minus two celsius in scotland and northern england and some of frost even in the south. high—pressure with us on monday, these weak weather fronts moving into the north—west later. for most on the start of obese if not chilly. there will be some more —— starts off a glorious. the threat of some outbreaks of rain in scotla nd of some outbreaks of rain in scotland not amounting to two much. the cool weather will not stay too

much longer. another cold made with a touch of frost, potentially, but we start to get more of a south—westerly winds on tuesday, bringing more mild conditions for most areas into tuesday. turning milder, cloud alone in western areas, best of the sunshine in the east and in the north—west of scotla nd east and in the north—west of scotland it will be when the bus outbreaks of rain. temperatures by the middle of the week is somewhat above average, will rain and western scotla nd above average, will rain and western scotland and the colder air in the far north. this is bbc news. i'm shaun ley. the headlines at 4. at least 300,000 march through barcelona in support of spanish unity and against catalonia's unilateral declaration of independence. the international trade minister, mark garnier, faces an investigation after he admitted asking his then secretary to buy sex toys. heathrow airport says it's investigating how details

—— heathrow airport says it is confident that it remains safe after security information was found in the street. parents will no longer be able to use a legal loophole to avoid paying child maintenance, under new laws to be brought in within months. lewis hamilton needs only a fifth—place finish in the mexican grand prix to be crowned world champion. and in half here on bbc news, witness speaks to the cia operative, who tracked down che guevara in 1967, just before he was killed.
