sebastian vettel has set a new lap record in practice ahead of qualifying for the austrian grand prix. he guided his car around the circuit ahead of lewis hamilton who was quickest on friday. max verstappen‘s car came to an unexplained halt towards the end of the session. britain's former olympic champion christine ohuruogu has announced her retirement from athletics. she's 3a now, and she said a combination of her studies and a niggling injury had restricted how much training she'd been able to do this year. the highlight of ohuruogu's career was 400 metre gold in beijing in 2008 and she retires with four olympic medals and five world championships medals to her name. hampshire are on top in the one—day cup final against kent. half centuries from tom alsop and rilee rossouw has helped them to 136 and

no wicket from their 22 overs after they were put into that. two days away from the start of wimbledon. and top seed caroline wozniacki will take on belarussian aryna sabalenka in the women's final at eastbourne today. sabalenka beat agnieszka radwanska, with wozniacki coming from behind and saving a match point before beating angelique kerber. wozniacki was the beaten finalist last year. and there's a surprise line—up in the men's final — slovakia's lukas lacko, who's ranked 94th in the world, will face germany mischa zverev — lacko beating italy's marco cecchinato in straight sets in the semis. british golfer bronte law is four shots off the pace at the half—way stage of the women's pga championship in illinois — she's in a pack on two—under—par, chasing the co—leaders ryu so—yeon, park sung—hyun and brooke henderson. in that group with law is the american angel yin,
12:32 pm
who pulled off the shot of the day. she had to take off her shoes and socks. she played it from the bank and hope to get it near. but that was for birdie. now time for this week's edition of click. can artificial intelligence out diagnose a doctor? can a phone bring a giraffe to life? and can this robot make thisjump? britain's national health service turns 70 this week,
12:33 pm
and it is struggling to keep up with the modern world. an increasing population who are living longer and who have evolving health—care needs has led to not enough hospital beds, not enough access to specialised treatment, not enough nurses, and not enough doctors. the situation in developing countries is, of course, far worse. for a start, there is nowhere near as much money, but where you do have money, you have the issue of poaching of medical staff by richer nations. 0ne hope is to plug the gap with artificial intelligence. ibm's watson, for instance, fed with tonnes of data about cancer, may one day be better at diagnosing it than human doctors, and the hope is that it could be cheaper. but more immediately, we are seeing the introduction of apps like san francisco—based senselink, which uses al to do a first diagnosis from symptoms
12:34 pm
that we fill in. in other words, doing some of the work of a traditional gp. while some are sceptical that doctors can be replaced in this way, this week, one company claims that its ai is now better than a doctor. jen copesta ke has been investigating. artificial intelligence has the potential to influence our lives in a way we cannot yet understand. nowhere more than healthcare, where decisions made by machines could be a matter of life and death. hello, louise — how can i help you? at an event this week in london, babylon health claimed its artificial intelligence software can now diagnose illnesses better than the average doctor. i think i might know what's been causing your symptoms. it's most likely to be called meniere‘s disease. the company has already launched gp at hand,
12:35 pm
providing remote access to medical services in london. but the only involvement of artificial intelligence here was an algorithm that runs you through a symptom—checker. you would still talk to a human doctor for the diagnosis. now babylon says its software has reached a point where it can pass a medical exam with a higher average grade than a person. what i found fascinating is that not only it performed as well as them, but in questions it had seen before, it had 98% accuracy. so, once a machine learns something, it neverforgets. there are clear implications for this test for people in the world who do not have access to healthcare. since 2016, babylon have provided its healthcare service to rwanda in central africa. sub—sa ha ran africa has 11% of the world's population, but carries a quarter
12:36 pm
of the world's disease burden, and has just as 3% of the world's medical staff. in rwanda, the country faced a particular catastrophe with its healthcare system, after suffering one of the worst atrocities in the last century. over 800,000 people were killed injust 100 days in the genocide of 1994. this memorial in kigali is the resting place of over 250,000 people who were killed in the area surrounding the capital. the genocide touched nearly every person in rwanda, decimating human resources. when the genocide ended, there were only 198 health professionals left for a population of over 6 million. it is difficult to overemphasise the challenges of rebuilding a society after such a tragedy. but today rwanda is regarded as an economic success story in africa. its president, paul kagame, has invited tech companies to the country to test their ideas.
12:37 pm
first drones and now artificial intelligence. we visited the offices of babylon, called babyl, in rwanda, with the coutnry‘s health minister. he is here to see a demonstration of how the ai triage works. the company already has 2 million registered users and has done thousands of consultations. babyl is using the same chat bot that its uk customers would use, but there are several differences here. most people use feature phones, not smart phones. so the service is provided by a nurse, who reads the text of the ai over the phone. this is the symptom checker which would refer the patient to a human doctor. with long waiting times and long
12:38 pm
walks between homes and health centres, patients using the app can save a lot of time. after speaking to the nurse via a chat bot, pacifique was able to pick up a prescription in about ten minutes. translation: you see? the service is easy. you can use at home and come to the hospital and they will see you immediately. babyl have employed several methods to get the message out to the general population here. they hold rallies around markets all over the country and do a lot of on—the—street outreach. many people we met were already met signed up. she has already registered. some had appointments. translation: it is really good because sometimes you take a taxi and pay 600,000 rwandan francs, and when you reach the hospital, you find the doctor is not there. but for others, there are several barriers for them using babyl. translation: i don't have a phone.
12:39 pm
and on the chat bot, the country wants to see more country—specific details integrated into the software. the artificial intelligence that is being tested here with babyl has been designed from the uk system but, as you know, public health issues are different in the uk and in rwanda. for example, malaria — we didn't find any question related to malaria. we need to give it some local context. so, we are developing models for those conditions that are not involved in the ai, such as tuberculosis, hiv, maternal and child health. things that are important for our context. back in the uk, babylon announced the results of its chat bot‘s performance versus human doctors. it said its diagnosis rate was 81% on its first attempt, versus 72% for a human.
12:40 pm
they calculated that average based on five years of medical exam results. but these results have been met with scepticism by some senior doctors, who've questioned the timing of the release. i would not, with the research that i do, go public on it, and have a big media event, before putting it through the scientific process, because i want to know that the research i am doing is defensible, is rigourous, and that my peers agree with it. and i don't think we have been through that process yet. this important debate will continue as artificial intelligence becomes more prevalent in our daily lives. certainly critical to this is finding safe and rigourously tested ways to integrate the technology into routine medical care. hello and welcome to the week in tech. it was the week that uber was granted a short—term licence to work in london.
12:41 pm
it ended an uncertain period for the company following the decision by transport for london not to renew its licence last september. at the time, tfl said the us taxi app was not a fit and proper operator. adobe revealed that they are working on artificial intelligence to find out if an image has been digitally altered. and the singles charts got another revamp, as sites like youtube and apple music will now cut towards the chart for the first time. it was also the week that facebook cancelled its plan to create drones to beam down internet connectivity from the sky. it was announced in 2014, but it has not been plain sailing for the social network, with its drones failing to achieve long flight times. and on the ground, the defence advanced research projects agency — or darpa to its friends — showed off a new combat vehicle that relied on an altogether different type of wheel. darpa claimed that the result will be improved manoeuvrability.
12:42 pm
and if you like nothing more than traditionally—made pizza, you might want to look away now. this pizza—making robot can spread the sauce and put the pizza in the oven, and even cut it for you. the company behind the robot says it does not work faster than a human pizzaiolo make up but could be more efficient by making several pizzas at the same time. deep in the heart of boston's jungle of cables, something stirs. it is a cheetah. and it is off for a prowl. we are starting to see walking robots like this trotting out of laboratories all
12:43 pm
around the world. now the important skill here is not that they can walk a particular route autonomously — they are usually controlled manually using games controllers. no, the amazing skill here is that they can walk and balance as competently as we can, even on the most unforgiving of terrain. ok, that is impressive. ok, that's slipped, lost its balance, and regained its balance. that is the important thing. whoa! good shot! how hard is this? very, very hard. people might not notice because we move our body very easily, but we have to make sure that we know that we have three times, four times more neurons for muscle movement than your actual forebrain. we have 700 muscles.
12:44 pm
we are trying to mimic this with using only twelve motor. still pretty darn hard. how close are we to robots like this being of practical use? what do we still need to get right? i think we're pretty close in terms of mobility, like walking around, climbing upstairs, and then turning. the hardest challenge is still using arms. i sent this to power plants with radiation activity. opening doors is difficult. you have to use arms. that is where autonomous control fails easily. so we are thinking about combining human manipulation combined with nearly autonomous navigation. so, a robot can pretty much go by itself. i have a door — now a human comes in. there's a force feed device, manipulate the arm
12:45 pm
and open the door. now it can go through autonomously. check this radiation level. you can do some simple manipulation. and professor kim has that in hand, too. really quick response. when the remote robot hits something, yeah, you feel the force. that really feels like it is underneath my hands. so how does the cheetah compare to the robots that seem to make all the headlines these days — those from the stable of boston dynamics? our lab is much younger. we have only done this up to seven years. we are much younger. our software is new. but i think our hardware is better. we started using electro motors for dynamic motions, then hydraulics, which is very efficient. after we are showing robots,
12:46 pm
i think eventually these kinds of machines will be much more useful and safe. our motors are different from those you find in a factory. those cannot handle impact and absorb energy. as you can see, our robot is landing in jumping by itself. —— and jumping and can do a dynamic stop. they certainly can, as demonstrated by this exclusive look at a previously unseen manoeuvre. laughs you cannot hear it, but our cameraman swore there. it wasn't pretty.
12:47 pm
but the thing is, it recovered and stayed upright. yeah. i know people who could not handle the recovery there. cheetah and its predecessors have already pulled off some pretty spectacular moves but, before we get too confident, let's remember this is still a work in progress. i think it's time to hand over to lara. augmented reality experiences seem to be all around us. but how close are we to being able to create our own? adobe's project aero hopes to bring ar to the masses and i have managed to get a preview of the prototype. unlike other products of adobe's, they are starting off by releasing
12:48 pm
a professional version. the animated image to be placed in the ar first needs to be created in photoshop and then moved into adobe's 2d and 3d tool, dimension. the end result gives resolution and quality they hope exceeds many other ar solutions out there. long—term, though, the hope is that something simple will be available for anybody to create the assets themselves. the aim is a platform agnostic finished product. we tap on behaviour and then we request what we want it to do. what does adobe's release mean for thisjourney into a new ar world? i think, really, for the apple, making such a big push for ar, it is such a significant detail, here. adobe getting involved is a pragmatic move. ar is becominig important. adobe are all about making tools
12:49 pm
that make contact easy. it makes complete sense that as this new medium emerges they would want to get involved in a creative tools to actually make it possible for creatives to make their content. but if what you really want to do is create your own simple, augmented reality, maybe using something like a child's favourite toy, then i have found an app that should be able to help. clone allows you to create 3d assets which can be exported into different formats. you may want to have something 3d printed, or you may want to put it into an ar world. you go to website and print this off. then place your item on top of it. if you have a recent version of ios you will not actually need this if you are using an iphone, but with some other devices you will. it is time to start recording. i need to walk around the object to film this so it recognises every part
12:50 pm
of it from every angle. this is a little bit time—consuming. there, we've got it. a 3d version of this giraffe. the scan isn't perfect but can be edited in the application. the models can be shared on social networks as well as saved in a variety of formats. of course, there is more to ar than just butterflies and giraffes but, for now, we are perfecting how we are going to create it. that was lara. and just as augmented reality is moving into the realms of artists, the movie industry is also feeling its effects. here's mark cislak in la. in 1902, movie—goers were thrilled by a trip to the moon. george melies‘ seminal silent movie
12:51 pm
delighted and amazed audiences. since the earliest days of cinema, camera trickery and visual effects have brought magic to the movies. these days, visual effects artists have an enormous amount of tools at their disposal, thanks to computers which can bring the fantastical to life. even in a world of computer—generated images and virtual actors, capturing stunning images in camera is a major bonus for lots of movie directors. that is precisely what this technology allows directors to do. the ar wall replaces the back of a movie set with what looks like a 3d cg image played on a screen. the ar wall system is live tracking a camera using hacked together virtual reality gear which is able to sense how the camera is moving and — you know, at 1000 hertz
12:52 pm
a second — and then adapt to the movement of the camera to create a perspective illusion that is appropriate for the changing perspective of the camera. michigan avenue preceding north to 42nd precinct. in hollywood's heyday, techniques like rear projection allowed actors to perform in environments which were much more controllable than the real world. sure. with traditional rear screen projection, which i was a huge fan of, growing up, the illusion has been around for decades, but there were limitations to it. the screen can sometimes look washed out in a rear screen projection. ar wall seeks to allow the camera a freedom of motion that you can just use it hand—held, however you want. lots of movies currently use green or blue screens for this purpose. and some films even go so far as to shoot entire scenes in green or blue screen, adding
12:53 pm
computer—generated effects including cg sets and characters in postproduction. it allows for a massive degree of flexibility as far as effects are concerned. not now, jean claude. but, achieving the level of visual effects of cg virtuosity as seen in modern blockbusters is very expensive. michael plescia wanted to make a short film called the mop liberator. problem is he had champagne cinematic tastes but a lemonade budget. the team wanted to develop the technology that lets you feel very kinetic animated characters running around through catwalks of a city, or a scene, and having the camera person follow the actors spontaneously. and not with preplanned camera moves.
12:54 pm
making this film would normally require extensive green screen work with the sci—fi city scape added in postproduction. they created a technique to bring a multi—million dollar vision to the screen for a fraction of what it would normally cost. it created this sort of — for actors — they are usually having to imagine what will fill the green space. with this technology, we had the luxury of projecting it, and actors could see exactly what movie they are in. that was mark in la. and, finally, with wimbledon starting on monday, i thought i would get in some practise on a court.
12:55 pm
and, of course, i brought along my robot buddy. the telebot autonomously patrols the court and collects the balls you lobbed, smashed or, in my case, mishit. for any ball boys and ball girls, worrying about their jobs, do not worry. this is not designed to replace you at tournaments but about people who are practising and are not very good. you can carry on practising. it will pick them up while you are busy being rubbish. its on board camera spots the balls and the partner at the net keeps track of things too. it also has a handy and detachable basket. you can take it to the car and no—one will ever suspect that you are the laziest
12:56 pm

wildfires out into the irish sea. looking at the weather picture over the last five days we have had exceptional heat, five days where temperatures have exceeded 30 celsius somewhere in the uk. we will probably do the same today and tomorrow as well. it has been quite a cloudy start to the date for some of us. we will have clear skies before long. —— to the day. not really a cloud in the sky for most of us. quite fresh in the north east of us. quite fresh in the north east of england and the east of scotland where the temperatures are in the low 20s and is bidding pleasant. temperatures will probably push into the low 30s in the hottest areas. —— and is feeling pleasant. we will see more cloud forming in the east of scotla nd more cloud forming in the east of scotland and the east of england and maybe ireland later in the night. temperature wise we're looking at
12:58 pm
lows between ten and 15 in towns and cities. subtle changes in the weather forecast. there will be thunderstorms in the south—west of england. otherwise, any morning cloud tending to melt away and perhaps an odd spot of wayne. otherwise it is a dry picture with lots of sunshine. south—easterly winds have developed through the day which will be dragging humid air across the continent. particularly in england and wales it will feel more humid and it will feel hot, probably one of the hottest days we have seen so far during the hot speuin have seen so far during the hot spell in london. temperature is around 32, 33 in the hottest areas. looking at the jet stream into next week, we still have a split pattern with one branch going towards iceland and another branch towards the mediterranean. we are stuck under some high pressure. more of
12:59 pm
that in the week ahead. most of us staying dry with a few isolated showers. that is the weather. good afternoon. the nhs in england has set out plans to stop hundreds of thousands of patients every year receiving treatments deemed ineffective or too risky. haemorrhoid surgery and treatment for varicose veins are among the procedures that will be restricted under the proposals. it's expected to save the nhs an estimated £200 million a year. kathryn stanczyszyn reports. some nhs treatments could be about to become much rarer. plans are being drawn up by nhs england to limit options that they say are ineffective or too risky.
