the headlines — president trump has changed his mind about endorsing the communique issued at the end of the g7 summit which highlights the importance of a rules—based trade system. in a tweet, he blamed what he called false statements by the canadian prime minister, justin trudeau. the us president is now on his way to singapore for talks with north korea's kimjong—un. mr trump says the meeting is a "one—time chance" for a peace deal. mr trump said the north korean leader could do "something very positive for his people, for himself, his family". at least 65 soldiers and police officers have been killed in four separate attacks carried out by the taliban in afghanistan. the violence comes on the same day the afghan taliban announced it will mark a three day ceasefire over the muslim festival of eid. now on bbc news, click. this week, technology meets football.

the robokeepers and kickers. and football fails. sorry... can intelligence be created artificially using silicon? or will organic living material like the human brain forever be the only way to support such powerful processors? it's a question we often explore here on click. ai researchers around the world insist that so—called in silico intelligence is already showing

that it will beat organic rival. but to them, i have one thing to say: paul the octopus. because during 2011 world cup, this animal oracle put the argument firmly and decisively to rest. paul's organic brain correctly predicted the results to eight world cup games in a row — an extraordinary feat. it brought him worldwide fame, and something no artificial intelligence could hope to match. sadly, paul then demonstrated the problems with organically—housed intelligence, and died a few months later, taking his incredible soothsaying gift with him, and leaving only this memorial to his remarkable talent. but now, as the world cup 2018 gets underway this week, one thing you don't need to be an octopus to predict is the fact that the world is yet again about to football crazy.

yes, as nations around the world shut down, and the next paul the octopus is waiting to be discovered, we thought we'd take a look at some of the technology behind the beautiful game. and we start with the ball — every single tournament, they unleash a brand—new model of these things. i know — it'sjust a ball, right? well, no — you see, an awful lot of work goes into the design and manufacture of these things. we sent kat hawkins to have a look. the new adidas telstar 18. i wanted to find out what goes into the design behind this, so i've come to loughborough university to find out. this year's design is a model re—version of the iconic adidas ball from the 1970 world cup, the telstar. but if you thought this was a case of aesthetics, think again. loughborough university have been

researching for adidas for almost 20 years, and their rigorous testing facilities offer findings on how the ball moves and reacts in different situations. hi, andy. hi, kat. first up, the team use a roboleg to recreate the moves the players make over and over again at different speeds and powers. we have a compromise here between the fluidity and flexibilty of a human player but the repeatability of a machine. even the best player in world cannot kick a ball the same way twice. yeah. if we want to know how a ball will respond, we need the robot. let's see it in action, then. i'm impressed already that the foot appears to be in front of the ball. three, two, one... woah! ok, so it is fast. so from our point of view, it would be understanding how long the boot is in contact with the ball, how the ball deforms, how it stores the energy, how it recovers that energy, and then that results in this sort of forward velocity and the spin that's imparted on the ball into its flight. but what we've just seen in the roboleg really has to make sense in terms of the players. yeah.

and so capturing what a player does when they kick a ball in a lot of detail to give us the inputs we need to control the kicking leg is absolutely vital. yeah. so done here we have a motion capture space where we can actually capture a player kicking a ball in all the detail that we need. as well as robotic legs and motion capture technology, the team here work on computer simulations of footballs to try to figure out how they will respond before they're made. we are simulating certain aspects of the ball. in this particular case, its the mechanics of the ball, how it performs under certain kicks or with collisions on different surfaces. perhaps modelling the flight might be possible sometime in the future, but, for now, the way do that is to look in the wind tunnel

and do experimental aerodynamic studies on real prototype balls. if i show you something of the scale of what was involved in a tunnel like this... so if we come outside, and you get a scale — a sense of the scale. so this is the air inlet, and then the air is expelled and here to similate the speeds that the player will kick at. wow, i was not expecting this. two goalkeepers who have played friendlies with the new telstar 18 have already complained about the design. spain's david de gea said it was "strange," and his teammate pepe reina called for it to be changed. whether the world cup is the right time to focus on technological changes has been suggested when players just want to perform at the top of their game. whether fans have anything to say about it will be seen when games start on the 14th. ‘s one thing that's never ceased to amaze me is how much people care. the football world cup is such a major tournament. it causes all kinds of emotions —

heartache and delight and everything in between. but we're interested in the game and the game works when it's balanced, where is a fair competition, where every player on the field has their opportunity to shine. and so our motivation in developing a load of the apparatus the tests that we have is to make sure that we have a fair representation to all the different uses of the ball on the field and make sure that their needs are all considered. that was kat. ok, ball done. but it is notjust about what we kick. like many sports this days, these days, data and technology are seeping into every part of the game. now, fifa has been notoriously slow about allowing technology to football, but this will be the first world cup where teams are given tablets to access data and analytics in—game. does that mean the data analysts

will become the new star players? well, we sent paul carter to fifa to find out. at this year's world cup finals in russia, data is set to play a bigger role than ever before. like it or not, data is already an integral part of modern football. you can't watch a televised game without being bombarded by all kinds of statistics. for the first time, fifa are providing an all—in—one technical package so technical staff can analyse data throughout matches in real—time. the snappily titled electronic tracking and performance system — or etps — will provide data on player metrics, such as distances run, speed, and position information. crucially, each of the 32 countries competing in the tournament will be provided with two tablets — one for data analyst in the stands, who will be able to communicate could with the second device user, on the bench, possibly a coach or assistant manager. we are using an optical tracking system. so we have optical tracking cameras

in all of the stadiums. we know where the players and ball are at any time of the match. we have different metrics available to the analysts, and it is up to them how they want to use this. with resources available for technology differing between countries, fifa hopes this technology will bridge the day to divide, bringing the digital haves closer to the digital have—nots. a lot of the teams already use data. we are expecting a lot of the teams to bring their own setup. but we want to use — at least offer the same to all of the teams. in fifa's system, the team's analysts will have access

to a tactical app, allowing them to add drawings to a live video field. stills can then be sent to the dugout. with goalline technology, video assistant referees, and now epts, this year's world cup looks to be the most advanced ever. but with all this technology, how big is the risk of losing the real spirit of the game? the role of the data analyst is — is simply to just — to again support the coaching decisions. i think the — there are some key insights that can be found in the data, but football will always be those 22 players on the pitch and the coach is always be the one making the decisions. at the end, what technology is really is for is only to support. but at the end it's — are you a big football fan? i'm a big football fan. at the end, the 22 players plus the referee, they are the main actors — 90 minutes — maybe penalty shoot—out. germany— england, maybe. so that — that's the excitement. and i think technology can only add additional help, optimise processes, optimise or providing additional information — that's what technology is about. hello and welcome

to the week in tech. it was a week which asus announced a phone so powerful they offered a cooling fan that clips onto it. microsoft sunk a data centre off the coast of orkey to test coolest efficiency. and facebook said it it's developed state—point liquid cooling that could allow it to put data centres in the desert. facebook needs cooling off after the week it's had. the cambridge analytica boss was again grilled by mps about its use of data gleaned from facebook users, and facebook itself was accused of handing over users‘ data to chinese mobile firms. facebook says it did it to improve its handset fb experience and has since stopped sharing quite so much. chinese vr specialists inter 360 came with a simple gadget that turns both cameras we already have on our mobile phones into superwide180s. an app then stitches

the footage together to create 360 degree videos. and finally, it was the week in which airline emirates revealed a windowless cabin — in first class. high—res images from fibre—optic cameras on the outside of the aircraft feed the projected windows inside the cabin. the airline eventually wants to get rid of all the windows to make planes that can fly higher and faster. it'sjune, i'm in sanjose, and there's excited developers everywhere — it must be time for a wwdc. more than 6000 developers are at this year's event — people of all ages. it's not to be clear time for new hardware to be announced. today is all about software. but it is a chance for apple to show what's in the pipeline.

the next version of ios — ios 12 — will be out later this year. you'll be able to stick your tongue out with animojis, and do a lot more with siri, which, let's face it, is not the most useful right now, but it might be. whenever i leave work, i canjust say "heading home." you will get there one hour. i sent a message to cheryl. your thermostat is set to 70 degrees, and i turned on the fan. playing kqed radio. multiplayer augmented reality will soon be possible. both players here can see the same virtual scene through their device. it's a mix of lego made from physical bricks and an interactive game layered on top. following in the footsteps of google, apple is also releasing a few tools to try and make you use

this thing a bit less. like google, apple thinks that telling you how much you are using and giving you the chance to set limits could be the big trick to curtailing your social media addiction. this app will monitor what you're doing and for how long, but it's still ultimately up to you to exercise some restraint. if you're a parent, however, you can impose tighter rules on what works on your child's device at certain times. but no sooner were apple telling us how it would help us be less addicted to our phones, it was adding a whole new load of features to the apple watch that demanded your attention. but perhaps the biggest announcement was, in many ways, the least glamorous — but many here think it could have a huge impact. apple says it will make it much more difficult for companies that collect data, specifically facebook, to find out information about who you are. and that will make it much harder for them to sell advertising.

if you use the safari browser, it will now warn you if something you're about to do, like typing into a comments box, will send data to a company like facebook. and so this year, we are shutting that down. not only that, but apple will make it difficult for tracking companies to know who you are by greatly reducing the amount of information it is possible for a company to gather about your computer as you visit certain sites. companies that rely on targeted ads to make their money will no doubt find a way to retaliate and work around these measures. but for now, it is apple one, advertisers nil. next, jane is finding out how often footballers can transport themselves into virtual matches. but first, she tries to outwit a classic piece of goalkeeping tech. he may not look like much,

but robokeeper can stop manchester's best players. his two cameras take up to 90 photos per second. if a football is kicked up to 100 kilometres an hour, that leaves robokeeper just 0.3 seconds to save the ball. bbc! here we go! there are some great facilities in manchester, as you might expect from one of the world's great footballing cities. normally practice requires a pitch, players to set up the drills, and footballs. but what if you can bring all of this into your living room?

we have come to salford city football ground to be put through our paces with the latest in virtual reality. first collecting data with statsports — they are working at the world cup with eight national teams including england. using a heart rate monitor and gps device fixed between our shoulder blades, we are sent on a run to collect data points. virtual reality platform mi hiepa sports transforms this data into vr amazingly quickly. that position that you were running, we have offset it back onto the pitch, so as we move forward, if we stream that data live from the gps vest we will be able to stream it live into this platform. so theoretically if you run in half—time or during the world cup, you will be able to review live tactics, positions, so this is the future of connecting those dots. mi hiepa have also created pressure drills in vr. lucy staniforth is captain of sunderland ladies and was shortlisted for the women's fa goal of the year. smashed it! the game realism is spot on, the defenders close on me, i felt real pressure. even just fine tuning little skills, some of that outside the box,

even the competitive edge in working on that was all good. another incredible development is being able to put yourself in any position in any game. obviously where raheem is, given that he is a fast player, he has the advantage coming in, the defender would have to turn their hips and try and turn it that way, i suppose. lucy is watching a real match that took place between man city and monaco. she can place herself in any position on the pitch — in the stands, on the roof, and even become the manager. right now i have a clear view of what went wrong in terms of the left back‘s positioning. do you see more detail of the players

and their bodies from this, rather than watching back on the match video? yeah i think so, because you are on their level and there is so much value in appreciating the picture they saw. so for the first time this is all portable. you can bring the match analysis loaded on an sd card or usb stick, load it onto the headset, put it in your bag and bring it with you, so if you are in the hotel the night before you can review the opponent's tactics from anywhere on the pitch. but to play against their virtual goalkeeper you have to be back on the wired version. vr, especially in contact sports, it takes out any chance of injury and it is more controllable and the fatigue level can be lower. i think it is really cutting edge, and we are glad to be getting involved in that space. you did quite well. spencer kelly with the nation's hopes on his shoulders... it is the last minute

of the world cup final, and this penalty will win it. can he handle the pressure? here he goes... if you are not a longtime fan of click, i can tell you that is as good as i get at football. but i wonder if technology even has an answer for this? we sent lara lewington, click‘s second worst player, because let's be honest, it would never work for me, to find out.

well, i'm certainly nowhere near ready to head to a football pitch, i need some sort of training first. but luckily we have come across this robotic leg which aims to help. i can see what the first problem is. this ur3 robot, originally built forfactory work, has already got its footy boot on. the idea is that it can repeat a human‘s movement, so they can be watched back and learned from, or it could be copying and teaching to kick of a star player from anywhere in the world. so here we have the setup. a kinect which will track the human‘s movement, and the robot should be able to replicate them, and we have a goal, and we can't do it without one of these. that's the theory anyway, but it didn't gauge the angle of my foot very well, and even i know you are not meant to kick the ball with your toe. but i did still need a little help from a human expert to understand

what else it was suggesting i did wrong. if we look closer to the robotic leg, we can see the ankle here is very flexible. so it's actually copying every movement you are doing. so the first problem you have got is, when you are kicking a football you have to open your arch. i followed the advice, it went to the right point of the net, i'm almost a professional! i've made it to an actual football pitch, albeit a five—a—side one, and i'm joined by the click team, what you think of our kit? good, aren't they? i need to do a bit more practice. they are kicking the ball around the old —fashioned way that i've a smart football here, and i've got an app with some augmented reality built in.

i've never done this before in my entire life. and i wanted to speed it up. ok, toe—taps. dribble up runs you through training suitable to your ability. after placing the ball in position the app will scan it and assess your every move. it's all gone red, i think i'm doing it wrong. i'm not sure this isn't footbal! i've never seen anyone train for football by doing this before. strangely, it didn't seem to think i had done too badly. i'm assuming these grades are for trying hard, because clearly i was absolutely ridiculous. it was quite fun, but i'm not sure i really exercised any sort of skills, the app works beautifully, it's lovely to look at, great instructions, but i don't think i was born to play football. now i've the moves, or not, it's time to learn some tactics. i need to actually be able to play the game. some mixed reality is here to help. this is soccer training on the microsoft hololens, teaching the rules through a mixed reality game, a lot of words, and questions to check

you've been paying attention. there's some text but i can't actually read the text properly. it's not quite the right position. there's the goalkeeper, and it explains the offside position. the premise is good, i like the virtual players running about, but it feels like hard work to watch because naturally you want to watch the people, but you need to be actually reading the words. so i tried to kick a ball around, thinking about everything a robotic leg, a smart football and microsoft hololens experience had taught me. but through no fault of the tech, i'm still monumentally useless. stephen, look over there! 0h! i had to find some way! that is it for our world cup show. next week we will be in the united states for the e3 videogame show in los angeles, and elsewhere in the country too. in fact by the time you see this we will already be there, tweeting at @bbcclick. so have a look, see what we are up to right now.

thanks for watching and we will see you in the states. for the vast majority of the country, saturday was another fine, dry and sunny one. it was warm, too. but there were some big thunderstorms across parts of scotland and the far north of england. sunday is looking similar. most places dry and warm with the heavy showers and thunderstorms developing into the afternoon. we are starting sunday off on a warm note, particularly across southern areas. variable cloud around. it might be disappointingly cloudy to start the day but the strong sunshine will get going on burning the cloud away and we will see some widespread sunny spells developing.

that will lift temperatures and thus will produce intense showers and thunderstorms. mainly central and eastern scotland, northern england and into wales and the south—west of england but most other areas staying dry altogether and warm. 23 - 25. a bit cooler nearer north—eastern coasts. into sunday evening and overnight, the showers and thunderstorms fizzle out and it becomes dry for most places. this is the pressure chart as we head into monday, high pressure still with us. subtle changes, we start to pick up northerly airflow around the high. it introduces more cloud to parts of scotland and parts of northern ireland through the day. for much of england and wales, dry with sunshine. the threat of a heavy shower or thunderstorm moving into the channel islands off the near continent. that is about it. most places will have another largely dry day. a few showers could develop across scotland. as we head into tuesday, it looks like it will be at bit cooler because we have northerly winds introducing more cloud to many eastern areas. it could feel cool in exposure to that northerly, for example, norfolk and northern scotland. temperatures a bit lower. 17- 20. now we start to see some changes as we head into wednesday. we lose the northerly winds. a ridge of high pressure keeps things warm and settled, but look, something we haven't seen for a while, a deep area of low pressure moving in off the atlantic.

for much of england, wales and south—east scotland, will be dry with variable cloud. good spells of sunshine. for northern ireland and western scotland, windier, cloudier, with more organised rain pushing in. something we haven't seen for quite a while. good news for gardeners and growers to see some significant rainfall and it could turn windy as we head into thursday with gales across parts of scotland. it will move south and east, tending to weaken as it moves, but it will bring rain to england and wales. for the week ahead, we are starting off dry and warm and it turns unsettled midweek onwards with some wind and rain in the forecast and it could feel fresher. finally, some changes to the weather. this is bbc news. i'm nkem ifejika. our top stories — president trump abandons a joint statement issued at the end of the g7 summit and slams the canadian prime minister as weak and dishonest. the us president is now on his way to singapore for historic talks with north korea's kim jong—un. more than 65 dead after taliban fighters launch a series of attacks on afghan forces, hours after promising a rare ceasefire for the muslim holiday of eid. back in germany, a 20—year old iraqi
