this is bbc news. the headlines: north korea is claiming it has test—fired what it calls a new type of tactical guided weapon, with a "powerful warhead". state media says the test was overseen by kimjung—un himself and describes it as having "weighty significance". crowds of supporters of the former president of peru, alan garcia, have gathered around his coffin. mr garcia shot himself as police arrived at his home to arrest him over corruption allegations. mr garcia was accused of taking bribes from a brazilian construction firm. robert mueller‘s long—awaited report on russian interference in the 2016 us election is to be published, in part, on thursday. attorney general william barr is to hold a press conference on it before the redacted version is published. that decision has been criticised by the democrats.

it is half past three in the morning. you are up—to—date on the headlines. now on bbc news, it's time for click. this week, the pope takes on robots. artificial intelligence takes up fishing. and gaming takes on robbie williams. # through it all, she offers me complexion... welcome to atelier des lumieres, paris. a mesmerising new digital exhibition by culture spaces, a french museum foundation that specialises in immersive art displays.

this former 19th—century foundry has been transformed to bring to life the paintings of vincent van gogh. it also gives visitors the chance to appreciate the influence japanese prints had on his work. the immersive audiovisual experience retraces the dutch master's life and work. using state—of—the—art visuals and 140 laser video projectors, the artist's works are transformed, becoming stunning moving images that are projected onto 10m—high walls. this truly adds a new depth to van gogh‘s work. you really feel you've been transported into his paintings. quite an emotional experience, i have to say. those behind the exhibition are also hoping that it will help to make fine arts more accessible, drawing in younger audiences who can interact with the projections and appreciate the masterpieces in a new and more modern way. first, another surprising instance where an old institution meets new technology,

this time courtesy of the vatican. jen copestake has been investigating how the church is influencing robotic research. robots. these days they seem to be everywhere. from badminton courts... ..to restaurants... ..to monasteries... ..and factories. they're augmenting our lives in various helpful ways. with many countries facing an ageing population, issues such as elderly care and access to doctors are being taken on by roboticist. in policing and even warfare, autonomous systems are rolled out

for police cars and drones. and with superfast 5g data networks around the corner, the capabilities of these machines could increase exponentially. this has led many to question the responsibilities that come with these capabilities. and the questions are coming notjust from silicon valley but from the heart of one of the world's major religions. at the vatican, the catholic church has brought together scientists and ethicists to discuss these issues, and pope francis has written a letter, the human community, which emphasises the urgent need to study the relationship between humans and emerging technologies. the pope presented the letter to the pontifical academy for life to open the special conference called robo—ethics: humans, machines and health.

one of the star attractions here is japanese professor hiroshi ishiguro, the creator of extremely humanlike robots. i am a humanoid. i am a copy of professor ishiguro. he has used them before to speak at his place in conferences but this time he has come in person. professor ishiguro presented his vision of the future of humanity, a world where humans evolved into robots, leaving behind our organic

bodies of flesh and blood. professor ishiguro says his vision of one day abandoning our current human form is several thousand years away. still, many here have doubts about this brave new world. this dream is a terrible dream. it is impossible to unify algorithms and love. algorithms and artists. it is crazy, it is part of us. i prefer our limits to our

really good perfection. professor ishiguro said one day humans would want to give robots their own rights, as we grow in relationships with them and welcome them into our homes as companions and helpers. but this is not a view shared by european governments. we are not of the opinion that robots should have rights on their own. the rights pertain to people. if you imagine that someday there'll be a robot that completely behaves like a human being, moves like a human being, looks like a human being, has facial expressions like a human being, how then will you decide whether this entity has a soul or not? so we have to discuss that, what that means.

for many gathered here, the idea of remaining human while dividing body and soul into inorganic and organic entities is impossible. but the pace of progress means these issues will continue to be discussed. this week the european union published a set of guidelines for ethical artificial intelligence, warning algorithms must not discriminate based on a person's gender, race or age. they suggested that in europe a person should always be told when they are interacting with an algorithm. earlier this year the vatican partnered with microsoft to offer an international prize on ethics and artificial intelligence, with pope francis meeting the compa ny‘s president, brad smith. thejudge will also focus on the ethics of ai at its meeting next year, as it continues to explore the relationship between humans and emerging technologies. a conversation which could not only affect our future of work, but also shape what defines us as human

beings. hello, and welcome to the week in tech. it was the week that authorities in the uk announced proposals for a new regulator for online and social media platforms to protect citizens from so—called "online harms". wikileaks founderjulian assange was arrested by police in london after ecuador withdrew his asylum. and facebook announced changes to how its algorithm handles the profiles of people who have died, to prevent friends and relatives getting notifications about birthdays or events. a commercial drone delivery service has been cleared for takeoff in the australian capital city of canberra following an 18—month trial. operated by alphabet subsidiary wing, the drones will deliver food and drink and over—the—counter chemist products. the drones are only allowed to fly

in daylight and must be 16 feet above humans while flying. supermarket giant walmart is to deploy autonomous machines across thousands of its stores in the us. featuring self—operating floor cleaners, shelf scanners and loaders, and pick—up towers, the devices willjoin the existing machines already in use in selected stores. the company says they will free up staff or other tasks. and finally, astronomers have finally taken the first—ever picture of a black hole. photographed by a network of eight telescopes across the world, measuring a0 billion kilometres across, the black hole, dubbed an "absolute monster," is 500 million trillion kilometres away. start saving those air miles. the home makeover show itself seems to be getting a makeover. i am behind the scenes at a new bbc show that's using virtual reality to reshape couples‘ homes before actually doing it in real life.

completely not what i expected. and it could get emotional. that's not the only challenge the producers of your home made perfect were up against. we're trying to make a really emotional, transformative tv show, and when people have got headsets on it's very hard to get that, to show that. what you do do, is you get great sound. you get oohs and aahs and amazing reactions from people. the show pitches two architects‘ visions against each other, giving homeowners the chance to really see their visions coming to life before deciding which option to go with. yeah, initially we didn't agree on what we wanted out of the house, whereas i wanted to keep the garden and get rid of the garage, and what actually happens is the opposite, i think.

yeah, switched. it's fascinating, we're notjust seeing the reaction to their home, but also the reaction to testing vr for the first time. it was so clever. the way they made it so real, with the dimensions. it wasjust like being there. it was really weird not being able to walk around because that's your initial thought process, because you're in the house and you want to see what's around the corner. you can't do that with the goggles on. but once you get used to it it's amazing. it was surreal, i thought. it was weird. a weird experience. despite everything else involved in this tv show, all the emotions, the fact that people are seeing their real homes, this is actually a really great, clear, immersive vr experience. this feels so real. i almost feel like i can reach that tap. the 360 element is absolutely fantastic. the one issue it has is, i can't actually walk anywhere, so if i go forward i'm not

actually going forward in the virtual world, i'm just likely to walk into something. 0pting for the samsung gear did mean some physical limitations compared to other vr systems. we did our original tests on an 0culus, and we used a vive as well, and we found that to actually animate something people could see and walk around, you couldn't actually get the graphics to high quality unless you had a supercomputer with an air—conditioning unit attached to it, and a cable. so what we realised was, we should be thinking of the end user. the vast number of people who are going to be watching this, hopefully, will be people watching it on screen on the tv. so we were looking for a way to use those final graphics as the graphics that our contributors see. so the best way we found to do that was to create 360 wraparound vfx which could be pretty high quality and play on a samsung,

just in a headset. this actually gives an idea of what open plan could feel like. revamping your home with the help of a spot of vr is not exclusive to a tv show. you can do it with one of these and one of these. planner 5d is just one example of an app that can do that, and would the android version you can use a headset. it's pretty simple to set up a project, although it is quite time—consuming putting in all the details. first of all, you need all your real measurements. you can even choose what the floor‘s going to look like and what the wall‘s going to look like, to make it true to life as possible. you can move things around in exactly the right dimensions to see where they and will not work. it's pretty impressive. it does look like a real room, and the detail is absolutely amazing. so, i can see the value in vr for architecture and interiors. it is just a matter of how people will feel about putting the work into make sure the result does it justice. that was lara. now, videogames have evolved from arcade—based entertainment into a creative art form as culturally vital

and powerful as film and music. hammering that point home, the london games festival plays host to a wide variety of game—related activities across the city. mark has been checking out some of the different events that make up the celebration of all things gaming. the london games festival is a place where smaller indie games are given an opportunity to shine alongside more well—known triple—a blockbuster titles. kicking off the festival, egx rezzed is an event packed with as much information as the big brand blockbusters. this is a mixture of football and a first person shooter, and you may think those things go together like fish fingers

and custard, but after playing for a short amount of time you will learn that flying robots punting the ball down the pitch would probably improve things in the premier league. get that ball away from my goal... back of the net! developed by dundee based studio earthbound games, the team behind axiom have plans to turn this fusion of football and flying machines into a spectator sport. it is notjust designed to be played, but to be watched as well. the streaming aspect of games has become huge over the past five years, so we believe over the next stage of spectators, will be interactive spectators, interacting in the way they would if they were at a live football match, for example. this collection of seemingly unrelated objects as a preview of the weirdness that is about to come when playing vr game

a ton of feathers. there is still something i don't understand... you have constructed a set up here that uses some crt monitors, what looks like an old tape deck, and a cuddly toy. i wanted to create a spectacle for people watching. he was the last human we had... also, i want to leave people with something to take away from the whole experience, so the soundtrack of the game is processed through a tape deck with an audio cassette tape for the output, so people can take home a little cassette tape of their custom journey throughout the game. time to try it out. the game has a story of sorts, a mystery about a serial killer. you all are right in front of me, as clear as day. it quickly becomes less of a mystery to solve and more of a pixelated psychedelic journey, exploring what a game actually is.

remove the plug behind you. it is like an 8—bit nightmare thought up by david lynch with help from max headroom. there is a parting gift, my audio recording of the whole experience. now all i have to do is find a tape deck. across town, here at somerset house, the now play this exhibition explores the potential of gaming technology. everybody who knows anything about games knows that this is a nintendo entertainment system, so—far—so—mid—80s gaming platform. but a closer look at the controllers reveals that they've had all their buttons removed except for one. so, how are we expected to play games on this with just one button? well, with a little help from up to eight friends. each controller has just one button that performs a different function. run left, run right, jump, so on.

in order to complete a game a group of people must work together. about ten years ago in 2006, there was a forum post in the accessibility forums, and moderators there for different accessibility groups were wondering what the history of videogames would look like if they were one switch, accessible to folks with limited manual dexterity. the first post in the thread was a nintendo entertainment system controller with one a button. so i wanted to make that image real and see what happens to play. suddenly, tetris is notjust about fitting blocks together the right way, it is about deciding, as if by committee, where to put the blocks. so everything becomes multiplayer. you might not expect to find karaoke at a games event, but malapropic karaoke raises the art to new levels. the machine plays popular tunes

but randomly generates lyrics, which though completely different from the originals, should still more or less rhyme. another demonstration that we should always challenge our preconceptions of what we consider to be a videogame, even if that challenge is not easy listening. throughout this programme we have been looking at how the traditional has been given a technological reboot, and to finish things off, it doesn't get much more traditional than sushi injapan, but even there, stephen beckett has been finding out how ai has been lending a helping hand to the raw ingredients — i.efish. japan's diet is often hailed for one of the reasons behind their world leading life expectancy.

but with people living longer and birthsjust not keeping up, finding enough people to filljobs is a growing crisis in the country. we are on our way to see kendai university's fish farm. around 12 million red sea bream are born and raised here every year and they make their ways onto the japanese dinner plates. fishing is an ancient industry here in japan, but around here they are starting to do things a little differently. you can start to see a few of the sea bream appearing now. these fish live in these ponds for about two years and then they are sold to other fish farms around japan, where they raise them even more, and eventually they are sold to restaurants. what do you think, have they had enough? it might seem serene here, but once a year things get a bit busier. during sorting season, all the fish have to be taken out of the ponds to be sold,

a manual process that requires teams of workers. workers who are becoming increasingly hard to find. in just a few days they need to check millions of fish, and to do that it is crucial that production line runs at peak performance. until now this has been the responsibility of this guy, whosejob it has been to regulate the flow using this dial. too slow and they won't check all the fish, too fast and they are likely to get overwhelmed. it might sound simple, but here only the most skilled workers are given the controls. well, the most skilled workers are now a new automation ai. the ai worker has been trained to recognise and count the fish as they come through the pump, meaning it can regulate the flowjust like it can regulate the flowjust like its human predecessor. translation: from dawn to dusk, somebody had to adjust the number of fish supplied, so we had to place a highly skilled person in that position all day, but this system allows us to relocate the person to do other work. the team claim that the ai worker is 90% as accurate as a human worker.

while it is not perfect it is good enough to get hired. behind the scenes, the software is running on microsoft's cloud computing platform. it's one of many companies like google and amazon cashing in o the idea of an ai future. what is really interesting here is just how easy ai is to use now. ai is available in the cloud and it is kind of plug and play. it is the democratisation of ai. so as you might expect, we are seeing ai being used in the manufacturing industry, the retail industry, but also primary industries like aquaculture and agriculture. the explosion of cloud services means even the most remote parts of the world can access specialised computing power like this. elsewhere on the farm they are exploring other ways to automate this traditionally hands—on process. internet—connected sensors are already monitoring the environment in the tanks. the hope is that in the future this data could be used to better care

for the fish. kendai university is getting the immediate benefit of removing some mundane tasks such as regulating the speed of the conveyor belt, but the data collected can be used for many things. to analyse the environment, the growth of the fish, so it can lead to better quality and higher yield. only one job so far has been handed over to the machines, but next they are looking at whether the more complex task of checking and sorting the fish can be done by automation as well. doing that would mean more jobs can be replaced, which injapan is essential to solving the looming worker shortage. it feels like ai is getting pretty good at solving problems like these and it is probably a matter of time before we are seeing it all over the place in similar situations. but we are still yet to see any of those massive industry—shifting ideas become a reality. it feels like this isjust the beginning. that was stephen beckett injapan, and that is it from us here in paris.

don't forget that we live all across social media. thanks for watching and we will see you soon. hello, thanks forjoining me. wednesday was a perfectly acceptable day for many parts of the british isles, but it may well be put in the shade by what we are expecting to see quite widely across the british isles on saturday. the temperatures could peak around london at 25 degrees. for those of you who have opted for the stay—cation for this particular holiday weekend, well, you're certainly beating those who have decided to head down anywhere really, from iberia right across to the eastern mediterranean.

the reason for our settled spell of weather is that the jet stream, as we move through the weekend and into the start of next week, should be well away from the british isles. we're trapped on its warmer side. you'll notice there is a pocket of somewhat cooler air not a million miles to the west of us as we start the new week. more on that in just a second. thursday starts off rather cloudy across eastern scotland and the eastern side of the pennines, but as the day gets going that cloud dissipates. a little bit of fair weather cloud, not much more than that. on the east coast the onshore breeze is around ten, 11, 12. inland is widely in the upper teens, if not in the 20s. for all that we have to thank that big area of high pressure, which i'm sure you're getting used to by now, it's been there over scandanavia for a wee while. it will certainly dominate many of us as we get on through the weekend. friday, just maybe the odd passing shower to start the day in eastern parts of scotland, but friday is a really glorious day across many parts of the british isles. and those temperatures, notjust a south—east phenomena.

widely in the upper teens. and again, many locations could see 20—21 or something in that order. a fly in the ointment as we move towards the weekend. the weather front will be pushed closer to the northern and western parts of scotland, maybe northern ireland too, tempering the feel of the day there certainly. but as i say, widely 22—23, maybe a 2a or 25 across the south—east. not much change into easter sunday, we will have the remnants of that weather front trying to work its way down across scotland, thickening the cloud here, the odd spot of rain more, i suspect, towards the far north—west. sunshine rather hazy across northern ireland. but elsewhere, if you've got plans for the outdoors, get out and enjoy it. a word to the wise, the pollen is really quite high at the moment. and if you're out for any length of time, the uv levels are also worthy of consideration. come monday, the jet stream just trying to work an area of low pressure close to the western side of the british isles, but those fronts lingering far out west for many. easter monday too looking

like a pretty decent day.
