talks with cabinet ministers has produced an agreement on future relations with the eu after brexit. the deal proposes continued free trade in goods between britain and the european union. but it says the current free movement of people will end. rescue teams in thailand say an air supply line has been installed in the cave where twelve boys and their football coach have been trapped for two weeks. there had been concern about falling oxygen levels as rescuers try to work out how to bring the boys to safety. china has retaliated against the us, matching tariffs imposed by washington worth $34 billion. beijing is accusing the trump administration of starting the "largest trade war in economic history". china's commerce ministry says it's lodged a complaint about the us with the world trade organization. now on bbc news it's time to click. this week, technology watchers

wimbledon. restores voices, floats above london and makes a lovely stirfry. the thing i love about mit in boston is that whenever you open a door and a basement you could run into anything. unless it runs into you first. which might be why, for the seventh straight year, mit has been named the world's number one university. and, iam named the world's number one university. and, i am going to say it, this is one of my favourite places in the world. what i love about mit is that it is all over the

place. the buildings have this brilliant higgledy—piggledy nature and inside is the same. here there is stuff all over the place. it is wonderful. the computer science and artificial intelligence lab, csail, is mit's ai powerhouse with some of the foremost researchers in the field. here, ai has taught itself to see—through walls while robots are being built to swim through our bodies. why? well i'll tell you later. it is obvious to me i —— that we are still only starting to explore how to use artificial intelligence and robotics. 20 years ago it was a task reserved for experts because robots were large and expensive. but today, everyone has access. the data are so

prevalent we can't help it see how we depend on it. artificial intelligence is creeping into every aspect of technology these days. ka nak into every aspect of technology these days. kanak it does raise interesting ethical questions. if you are online in 2014, you were

aware of the ice bucket challenge. it raised millions of dollars for research in two the disease. are very identity. here in yonkers in new york, one man who lost this voice to motor neurone disease has been given back this sense of self through technology. project re— voice is an international initiative to help give people their voice back. using software from a canada —based company, lyre bird, it can synthesise inaccurate recreation of someone's voice from a relatively small amount of audio. lyrebirds softwa re small amount of audio. lyrebirds software was famously and co ntroversially software was famously and controversially used last year to recreate the voices of us president. iam nota recreate the voices of us president. i am not a robot. my internation is different. patter was one of the

early cofounders of the challenge. he was diagnosed with als in march 2013. the extent of this illness means he cannot speak. he was one of the first to be given this voice back by project re— voice. one of the things that we hear from people with als is that they comment you know, that their voice really reflects themselves and their own thinking about themselves. we also hear it from their family members and that is really where, you know, people say that we were not thinking about the fact that we would not be up about the fact that we would not be up to hear this person speak any longer until it was gone. and now, suddenly, we mist their voice and mist that side of them. so there is something inherently unique about a person's voice that hopefully we are able to capture and keep in the future. pat concedes this new voice is not perfect. because he did not record this voice prior to losing

it, lyre bird used online video and speeches as their basis. laboured's algorithm analyse several hours of quality recordings to analyse a person speech. i don't think any companies before have done something that allow people to copy their voice off a small amount of audio. so this is a research subject and it has been going on for the 30 years. but what we provide is for people to do it in their home and you can go to our website, record yourself a few minutes,. the hope is to extend the scope of

project re— voice more people internationally, to allow more people with mnd and als to recapture and recreate their own voice. this voice is terrible. i hate it. i it sounds like a professor i would not listen to. with project re- voice we would like to see a person's voice be accessible as possible to them so that they can use their voice whenever they want to use it. and haveit whenever they want to use it. and have it be ease—of—use, true ease—of—use. with voice banking and voice messaging in general we just wa nt voice messaging in general we just want to try and bring it to as many people as we can and in as easy as possible and truly make it commonplace for people to be using in theirown commonplace for people to be using in their own authentic voices when they communicate. hello and welcome to the week in

tech. it was the week that a security researcher discovered that wearing 00 style cloud make—up could fall some facial recognition systems. the skies are fans of hip—hop outfits the insane cloud posse. thousands of fortnight players infected their computers with malware after downloading cheap softwa re with malware after downloading cheap software to try and improve their game. they say trailers give away the best it is of the film. somebody at sony pictures is in hot water after uploading the entire movie to youtube instead of just after uploading the entire movie to youtube instead ofjust the trailer. researchers at harvard have developed a robotic cockroach that can work what might walk on land and water and even go for a dive. the amulet or a micro robot applies a voltage to the water in order to break the surface tension, allowing

it to go free swim. from walking on water to flying through the air with the greatest of ease. we have seen disney's stunt robot before but it has had an upgrade and now has a humid looking body. the autonomous self—correcting aerial robot to make adjustments in the air to make sure it nails it is death—defying leaps again and again. finally, the next time you are trapped on a desert island want to make a romantic declaration in the sand, why not get a robot to do it? this little robot makes strides in the sand, acting like a beach printer. may not be the quickest mass —— way to get your sos message out though. bringing out to the masses through technology is something many have tried to achieve over the past few yea rs. tried to achieve over the past few years. but here in london's hyde park there is something pretty big on display. so how can we see this recreated in a way that more people

could see? this is named after an egyptian tomb meaning eternal house. this one is only temporary. it is made up of 7506 barrels and weighing 600 tons. if you are here, you can not exactly mist it. for those who are not in the vicinity, being able to enjoy this or being able to see from all angles in the day or in the night—time light, well, you could do so night—time light, well, you could do so with one of these. a google cardboard version provides a basic look around the installation. but a fuller experience as possible using the h is seen five or steam. outcome in doors to do this because it does not matter where i am and i need a good wi—fi connection. so let's go.

ican get good wi—fi connection. so let's go. i can get up to five metres away, i believe. now time to start flying. 0k. believe. now time to start flying. ok. that is impressive when you can see over the other side. it is quiet. no—one in the park today. the night—time view is still a work in progress but i did get to see the su btle progress but i did get to see the subtle shadows and colours changed through the day. i am no stranger to a spot of vr but from an art perspective, i would like a second opinion. let's see ifi can perspective, i would like a second opinion. let's see if i can go over the top. it is wonderful to do this. that is a fantastic aerial view. problem is you start to get a bit tourist and look at the young comment london i london skyline. comment london —— london skyline. let me help you. what i think was fascinating for me is that you are an art expert yet you were more distracted by the london skyline, the park and the lack of people than actually being able to focus on the art. that is the trouble with this

kind of thing. perhapsjust art. that is the trouble with this kind of thing. perhaps just for all dinosaurs like me but there is still something quite thrilling about being able to go up in the air. this isa being able to go up in the air. this is a great piece but i would argue that actually at impact is a physical impact that when you walk in the serpentine, walk in hyde park and you come across this extraordinary mass, the scale of it, all that stuff, that does not come through on the vr. with a version 50 times the size planned for the derby, you can see that scale is clearly im porta nt derby, you can see that scale is clearly important here. but while it may be a lot easier to create that ina may be a lot easier to create that in a virtual world, it is may be missing the point. that was lara. 0k. act missing the point. that was lara. ok. act to missing the point. that was lara. 0k. act to mit in missing the point. that was lara. ok. act to mit in boston now where i am walking around and around and around in order for an artificial intelligence to track me. that is me that you can see on that screen there. but what is really impressive

here is the detector is not in this room at all. it is next door and it is seeing through this wall. it is called rf pose and the transmitter uses called rf pose and the transmitter uses low powered radio signals that pass through walls but reflect off objects in the next room. everything reflects. not just the objects in the next room. everything reflects. notjust the human body. the ceiling, the walls, everything. to make sense that mass and focus on the human body, you had to eliminate of them and that is a complex programme for machine learning and deep learning. it is good at that. the system has taught itself to pull out the human skeleton from the mass of reflected signals and it can deal with many bodies in the room and, of course, it can see in the dark as well. the professor would like this to be used for healthcare as a way of checking on elderly patients without capturing any sensitive personal information or any actual images. in fact, the software is so sensitive it can even detect

heartbeat. you could check for sleep apnoea, for example, that is disruption of breathing during sleep. use all the heat ‘s moment by moment so you sleep. use all the heat ‘s moment by moment so you can sleep. use all the heat ‘s moment by moment so you can look at the interval, the time between europe regional beats and look for arrhythmia. i have to say, on this trip to boston, i have noticed an interesting thing. and acceptance that artificial intelligence has its limits. the team behind the self balancing cheater robot want to fit it with human control the arms because ai is not up to the job of opening doors and manipulating objects, not yet anyway. and a com pletely objects, not yet anyway. and a completely different piece of research is also a shoring —— issuing ai altogether. this is an idea that hopes to block e—mails containing bullying, harassment and hate. what is interesting is that here we are in the artificial intelligence department that you are

basically saying ai is not cut out for this and we need to go back to humans. from talking to people who deal with harassment without harassment was really contextual. it is personalised, often to the person getting harassed, because often the person harassing them is sometimes using something that they know about that person to harass them. and so we think that something like ai isn't going to be able to cover all the ways people are getting harassed, and in fact people might be adversarial it trying to get around the things that a model might be learning. they will have a very innocuous title for the email, and maybe their harassment will be hidden near the bottom and you have to go and read it. it is an idea called squad box, and its aim is to use not a computer but your friends to spot and manage harassing emails. the idea is simple. messages are intercepted and redirected to a

squad of moderators that you have chosen, and who will probably understand what is personally offensive to you, even if it doesn't contain the obvious keywords. what is really interesting here is that there are no swear words in here. i think your work is fake and you are just out to make a profit off the backs of ha rd—working just out to make a profit off the backs of hard—working people, you should really re—evaluate your life. ican should really re—evaluate your life. i can see how an algorithm would pass that, that's fine. for now, squad box has been geared to work with email, but its creators say that it couldn't be ported to work with social media, and certainly the moderation approach sounds very social. cecale is also at the forefront of robotics, building machines in shapes and sizes that challenge our very idea of what a robot is. primer, the so—called superhero robot, picks up different outfits, or miniature exoskeleton is, depending on what it needs to do. off he goes!

it is like a really cool buying more. for long journeys it can roll up more. for long journeys it can roll up intoa more. for long journeys it can roll up into a wheel. to cross water, it dons a fold up boat and set sail. and if need be, it can abandon ship as well. the tiny transformer can even strap on a pair of wings and glide off into the future. so, this can be used for some medical applications. for example, we developed, last summer, we developed this kind of stomach, a simulation. so we have an origami robot, similar. we are encapsulates it into ice, so it is like capsule, so when we deploy it into the stomach...m will melt in the stomach? exactly, then we can the electra magnetic field to move this little robotic pill, to move to the point where we wa nt to pill, to move to the point where we want to deploy the drugs or remove

something from your stomach. like foreign object you have swallowed. yes. primer is controlled by manipulating a magnetic field and it uses a heating pad to help it fold. right now you drive it using a makeshift controller. can i play? yeah, just... this is really cute. so, what might this be used for in the future? we could use it for space exploration, we could launch out and send out a stack of different exoskeleton is. they use one small single robot. elsewhere in the lab, here is an experiment in origami inspired robotic muscles which can lift 1000 times their own weight. it is going to break my scapular! last week you will remember this robot, which followed me around collect in my tennis balls

asi me around collect in my tennis balls as i prepared for wimbledon. sadly, ididn't as i prepared for wimbledon. sadly, i didn't quite make the draw. but it turns out jamie koe staked it. i didn't quite make the draw. but it turns outjamie koe staked it. yes, it isa turns outjamie koe staked it. yes, it is a beautiful day here at wimbledon. we are checking out all the technology behind the tennis tradition. artificial intelligence gets everywhere these days. even here at the all england club, where ibm's watson is busy at work behind the scenes. we are going to see three ways ai is being utilised at the turn and for content creators, players and fans. first, content creation. where are we right now? we are below broadcast centre. this is what we affectionately referred to as the bunkers. any chance of running into roger federer down here? possibly in the media room around the corner. watson's incredible processing data power is being used to create highlighting wheels with no human involvement. listening to the noise of the crowd

and listening for those really exciting moments. taking in the audio feed from the side of the court, and you know those rounds you get where you get the real oohs and aahs. so if the crowd excited, it might that down as an exciting point. it is looking at the data poised to think, where are the pressure points in the match? it also looks at how the players react. how animated they are with their arms, how obviously emotive they are one they do that. it combines those together to create an excitement level and that gets fed into this dashboard and all of the points are ranked, and at the end of the match, watson will also generate a highlight is package based on those exciting points, and they give that to the content team so we can get out quickly. players can also take advantage of this quick turnaround of highlights. instead of going through hours of video, each team is given a unique website to check. here is roger federer‘s unforced errors. this helps coaches create a narrative of what happened in the game and quickly see where they can

improve orbited their opponents. players, we sort of sometimes forget they are really the biggest fans of their own sport, and they want to know how their friends are getting on, their rivals are getting on, but also those statistics and inside that helps them in their own analysis of how they are plain, that is really valuable as well. and for fa ns is really valuable as well. and for fans who want deep analysis, they can get it by accessing all of the statistics via wimbledon's new facebook message of bot. that is also driven by watson. watson has one final data trick to show off. it is the first nonhuman to design a wimbledon poster. celebrating 150 yea rs of wimbledon poster. celebrating 150 years of the all england club. it uses visual recognition to scan of a 300,000 historic photographs. the final result is this mosaic made up of 8400 individual images. instead of 8400 individual images. instead of the usual colour matching, watson was taught to recognise the different elements of a photograph, such as umbrellas, and find umbrella photos to match. even the texture of

the court is made up of other photographs of courts. well played. that was jen at wimbledon. that wasjen at wimbledon. back in boston, my robot tour has left me hungry for more. the spyce restau ra nt hungry for more. the spyce restaurant is where i'm going to feed my need. touchscreens take the orders, robots cook the meals, and the humans are relegated to the source stations. chicken rice... and orange delivery box soups up and down a track transporting ingredients and dropping them into seven specially designed spinning at potts. they toss the food, keeping a co nsta nt potts. they toss the food, keeping a constant temperature via an induction plate. the only thing letting down this computerised cohort of wok wielders is arguably

the people in charge of delivery. they haven't called my name out yet. it was there all along. look at that. was i supposed to get a drink with my order? ok. thank you. the concept is the brainchild of the spice boys, four mit graduates who spotted a gap in this in this field to bye. early on, the first prototype, the first idea of design was about three and a half years ago. one of the key things that we made sure to pay attention to while designing this was, you know, it is a food robot, it has to handle food. food is so unique, it comes in all different sizes and textures, and one of the key focuses was to design all of this it could wear it would handle the food gently and preserve the quality preserve the integrity of the food, while being able to, just, you know, use the wide of food you see on our menu. just, you know, use the wide of food you see on our menu. now, just, you know, use the wide of food you see on our menu. now, this is obviously only suited to stirfries,

and maybe other dishes where everything is cooked together, and presentation is not an issue. if you wa nt presentation is not an issue. if you want a stake, potatoes and a drizzle of red winejus, want a stake, potatoes and a drizzle of red wine jus, you will need a com pletely of red wine jus, you will need a completely different robot. well, that's it from this robot restau ra nt, that's it from this robot restaurant, and that's the end of a us trip for this time. i hope you've enjoyed it. you can see more of us on facebook and twitter throughout the week. thanks for watching. and would you like some kale? for many of us it will be another hot day with temperatures exceeding 30 degrees across the south and temperatures reaching 31 on friday and we will easily make that on saturday.

having said that, there will be a little more cloud around during the course of the weekend. some areas may be overcast from time to time. the atlantic weather system is away to the north of us, still closer to iceland so that is why we are still dry. there is no change as far as the eye can see, at least through the weekend into most of next week indeed the whole of next week. bad news for gardens and parks. a lot of scorched grass out there at the moment. these temperatures first thing in the morning. 17 in london, 13 in newcastle. and then the temperatures shoot up rapidly. a lot of sun around but it will be cloudy from time to time, particularly around north—western and eastern areas, picking up cloud, and cloud is also developing across midland. 30 degrees of least in london, i suspect temperatures could reach 31 also. in the north of the country, closer to the mid—teens.

high—pressure front with us through the weekend however a cool front nudges into scotland and that means a little more cloud here for the north—west of scotland and the western isles in general. may be some spots of rain and these atlantic fresh winds. across the north—west here it will be quite a bit cooler on sunday with temperatures perhaps in the teens whereas to the south of that it will be hot to very hot. temperatures across the south could peak at around 32 celsius on sunday, reaching 90 fahrenheit. newcastle will be the pleasant 24 celsius. not much change on the way next week, staying dry, but it will not be quite as hot. it looks as though the heat will be pushed back into europe and we will see slightly cooler air riding around this high pressure because the wind around the high—pressure blow in a clockwise direction. this air will be pushed back into the uk which means we will see more and more northern parts of the country with slightly fresh air. still mostly in the 20s, we're not talking about it necessarily cooling off a great deal. on monday it is still in the high 20s across the south. it is only when we reach tuesday or wednesday

that we get back down to the mid—20s. in the north we are closer to the teens. that is it for me. bye— bye. welcome to bbc news — broadcasting to viewers in north america on pbs and around the globe. my name is nkem ifejika. our top stories: a brexit breakthrough. the british prime minster says cabinet ministers are backing her plan for leaving the european union. this is a proposal that i believe will be good for the uk and the european union, and i look forward to it being received positively. the us and north korea agree to set up a joint working group on denuclearization after mike pompeo's latest trip to pyongyang. divers in thailand succeed in getting an air line to the cave
