damage limitation still in full swing after president trump's bizarre press conference with the russian leader in helsinki. mr trump has said again that he really does accept the conclusion of us intelligence agencies that russia interfered in the 2016 us election, and now says he holds vladimir putin personally responsible. he was speaking to cbs news. the group of boys from thailand who spent two weeks trapped in a flooded cave have paid tribute to the team who found them, describing their rescue as "a miracle". and they honoured saman gunan — the former thai navy seal who died preparing their escape route. the european commission has fined google a record $5 billion over the use of its android operating system. the commission says the tech giant illegally used the technology to "cement its dominant position" in searches. google plans to appeal. —— and denies any wrongdoing. it is just after 3:30am, it is time

for click. fed up of the football? your team's gone out? well, let's talk cars instead. this week, we're at the grand prix. we're in a do—it—yourself driving car in india. and, someone getjen a new umbrella. commentator: the seconds wound down before the start. 2a drivers step hard on the throttle. formula 1 has been at the cutting edge of technology and design since its creation in 1946. welcome to the pit. every year, teams compete fiercely to outdo each other in aerodynamics, data communication and materials, all with one aim — to make their cars go really, really fast. and they do a really good job of making them that, as we are finding out here at the austrian grand prix. lewis hamilton's ride. what's even more impressive is that this whole show is permanently on the road, with car, teams, engineers and scientists moving from country to country and track to track. now, these are the most expensive motorhomes i've ever seen.

each one of these is a lorry, and theyjust drive them to the next formula 1, stick them together, zip, zip, zip, and that's ferrari's office for the duration of the race. —— office for the length of the race. and ahead of the base here in spielberg, austria, the cars are being prepped, tweaked and tested around the clock. mercedes are the current world champions, and like every other team here, they spend millions on their car and developing the technology that will hopefully win them the race. but what you see at any grand prix is just the tip of the iceberg. it takes hundreds of people to develop that technology. so we sent lara lewington to mercedes hq to find out what really goes into winning a race. away from the track, the people, the planning, the preparation and the precision are pivotal. hi, i'm lara lewington from the bbc.

hello. can ijust put security stickers on your phone? of course, no problem. so we're allowed to film here but i mustn't take any pictures on my phone. there's clearly a lot at stake here, so it's no surprise that formula 1 is notoriously secretive. but today, we've got some behind—the—scenes access. this business is big bucks and millimetres and milliseconds matter. this is known as chassis number five — last year's winning car. in fact, it hasn't even been cleaned since its last race in abu dhabi. but the thing that is most striking standing here next to it is the amount of detail there is everywhere throughout the car and, after each race, if there's something they're not happy with, it can be perfected.

well, this was a winning car last year so clearly it's been very successful, but you're obviously not happy with it because you're working on a new one. so what do you think needs to be improved? we're never happy with it, as you say. this is lewis's car, from last year. it was the first car we made on the back of a really big regulation change. we worked really hard on all those little small bits you see around the car, which are all the aerodynamic bits and pieces. it seems to be made up of lots of little small bits. yeah, every little bit has a job and we put it into the wind tunnel and each one is about optimising the airflow around the car. but we are not happy with it here because we focused so much on that, we now need to do a lot on the packaging internally to make it much tighter. the tighter you get it, again, the better you can get the aerodynamics around the car. on top of that as well, we think we can do improvements around the cooling. those big, black ducts on the side is where the air goes in to cool the engine.

we think we can do some improvements around that area for next year. well, there is so much money at stake here. how much does it cost to create a car like this? from the beginning of the process, all the way through, what sort of figure would you put on that? well, i can't tell you the exact figure, but i can tell you it's many, many millions. are we talking tens of millions? tens of millions, yeah. tens of millions? over 50 million? close. crikey, i wouldn't want to pay the insurance premium on that! the operation here goes way beyond the car itself, though. welcome to the race support room. when a race is actually on, 60 members of the team are allowed to be at the track, so this provides the opportunity for more people to be looking at the data and making sure that vital advice can be provided. now, on these screens, they'll be looking at a feed from the race. they'll also be looking at feeds from within the drivers‘ cars, plus all the vital data that they want to act on, and if they want to communicate, well, then they simply do it through a pair of these. lap times, gps data, everything can be tracked and analysed here, where 5000 different data points are being assessed.

information from races in europe taking just 0.1 of a second to reach here, or 0.4 if the data is coming from australia. meanwhile, this lot are busy practising at speed. over 250 of these trials take place ahead of the season. they make it look easy, but inevitably it's not, as i can tell you first hand. 0h! oh no! it's meant to be so quick, but i clearly wasn't. meanwhile, spencer's already living life in the fast lane. thank you, lara. and by the way, this is how you really do it. laughs this year, mercedes has

got its pit stop down to an incredible 1.85 seconds. now that's quicker than it takes to say "1.85 seconds". it's a finely tuned operation that the engineers practice over and over in the days before each race. it's a bit of a ballet and the ergonomics is quite important because it's 20—odd people around the car, trying to do a job in two seconds. and it's — if you start banging into people, then you're losing half a second, a second, and then the strategists can't get their numbers right and then you don't get the position you need. the human element to this ultrafast manoeuvre is accompanied by technology, individually developed by each team. even the hydraulically powered wheel guns are a closely guarded secret. and i hear they're quite expensive. they are expensive and they have

a life because they're under an awful lot of pressure, so we are changing the internals a great deal. do i hear about £30,000 each? i wouldn't know the exact cost, but that sounds quite low to me. right, we're going into mercedes‘ garage now. keeping the pit crew safe is of utmost importance. these lights, for example, let the crew know if the cars have become electrified, stopping them from getting more than a nasty shock. and then there's what goes into the cars, or more specifically, what comes out of the cars, which is monitored by trackside labs and high—end scientific equipment. between every session, the cars are given the equivalent of a blood test. the oil and the fuel is taken to see if it's contaminated, and that might give you a clue as to the state of the engine, and that is done in the fuel lab. the oil is put into a spectrometer, which tests for different metals in the fluid. the amount of a specific metal present can reveal if a particular part of the engine is

degrading too quickly. yes, these may be some of the most skilful drivers in the world but i wonder if even they would struggle with driving in david reid's neck of the woods. ok, here we go. this is maximum chaos! this guyjust overtakes me on the inside. it's crazy! horn blares a car sandwich. yeah, that's me. thank you. driving here is tough. i reckon if western autonomous carmakers came here, they would hide in their hotel rooms. but indian inventors, they see the chaos on the roads here and they want to take it on. look at this mobile footage. this rickety second—hand suv has been made single—handedly into a self—driving car. it's a bit rough, but it makes it down the sort of road that gets wing mirrors very worried indeed.

the man behind it is sanjeev sharma, a us—educated a! specialist. he says the maths that navigates his car, the algorithm, has been designed specially for india's nightmare roads. indian traffic is very chaotic, so it's very hard to predict. once you solve that prediction problem, then you can apply that to any restriction environment and it will work, because you have already tested it in the most difficult conditions possible. today, there's a hitch. the car is refusing to drive itself, so he takes the wheel. top—end driverless cars cost a bomb. they're developed by big teams, have pricey radar and lasers, and use big data maps to find their way. sanjeev‘s is cheap but not short on brains. his off—the—shelf cameras talk to an algorithm that reads the road, even without maps.

india's government is against driverless cars because they fear job losses, but the tech being developed here could still travel far, especially with the advent of artificial intelligence. now, whether or not at some time in the future india will have driverless cars is very debatable. however, the same technology can be used to make india's roads safer. many here place their faith in dashboard—mounted gods to protect them. please maintain safe distance. but with 150,000 dying on india's roads annually, driver i, a hazard warning system developed in bangalore, might also merit a look—in. beeping so why did it go there? it is too close to the left and it was about to collide and that is why it was detected.

and it's just as well, because they were policemen. driver i is a clever back—seat driver. so this is the front camera. it measures acceleration, orientation and it has ag, but also artificial intelligence — it learns what's safe and what's not. it's helping indian truckers drive better. we're tracking every single object on the road and we're basically measuring any unsafe, and identifying any unsafe event. we actually identify what the driver's manoeuvre is and whether the driver's manoeuvre corresponds to a positive manoeuvre, or if it was actually something that the driver can improve upon and the driver did something that could be considered unsafe. like our run—in with the cops — we got the video because driver i sent it back when the warning sounded. one rather surprising area where driverless technology is making inroads is actually off—road. in chennai, one of india's main carmakers is developing self—driving tractors in response to low crop yields and the lack

of farm workers. tractors can work around the clock — just what you need when you are up against a short window for sowing or harvesting. when it has to happen, it has to happen right at that time, otherwise you can actually lose the interlude for the season. it's not an easy piece of equipment to drive because you don't want the wheels to run over the seedlings every time, so every time can you get that consistent operation? and that can be done only by technology. on or off road, self—driving tech has incredible potential — helping out farmers, disciplining unruly drivers, and harnessing chaos as a testbed for even smarter systems. hello, and welcome to the week in tech. it was the week that facebook faced a fine of £500,000

for breaches in the cambridge analytica data scandal. and we learned the scale of apple's autonomous vehicle ambitions. a court filing accusing a former employee of stealing trade secrets has revealed that 5000 of the company's staff know about the project. the smartphone supremo has remained notoriously tight—lipped on the issue. across the channel, a family in france have become the first to live in a 3d—printed house. their cement—filled home in nantes was built in just 5a hours. but the city's university and council behind the project think they could do it all again injust 33 hours. its curved walls make the property less humid and the construction costs were 20% cheaper than using traditional methods. it was also the week chip—maker nvidia showed off its photography skills. using deep learning, it has trained it a! to fix grainy or corrupted images. amazingly, it has learnt how to do this having

seen corrupted ones. which means it could make restoring poor pictures easier in the future. magic! and finally, mit have designed a musical instrument specifically for space travel. it contains chimes that are equipped with gyroscopes that change sound, depending on how they are shaken. it allows budding astronaut musicians to beat the box in zero g. the stats for formula 1are mind—blowing. these cars come around this track at over 350 km/h and that is why 350 million fans tune in to these races. but attracting new viewers is a bit of an issue for this sport because watching these cars go around and around and around and around can get a bit boring. formula 1 are aware of the problem and part of their strategy is to use

all the latest tricks and technologies and technologies to pull in new fans, especially those who play racing video games and are used to feeling like they are really sitting in the driving seat. sport broadcasting technology is moving at such a pace. we are talking about 3d, 360, virtual reality. that is a big talking point at the moment. mixed reality is quite nice as well. whether that is bringing in actual footage against the cg! world. the demographic for a formula 1 fan, i believe, is a middle—aged man. we want to make it available for young people, boys and girls, all sorts of people. this year every formula 1 car has one of these cameras right on the front. that is correct. why have you done this? to give the public a more interactive feel.

you can actually go wherever the action is, and if you record it, you can watch it back at whatever angle you want. and have you tried this? what's it like when you actually look through the goggles? we haven't found anybody who hasn't been wowed by it. it is our intention that you can pick your favourite driver and have an experience with him going around the track. but while this may be a great experience for the viewer, the teams, which consider every centimetre of these cars, might not be so happy about formula 1's mandatory addition. the original camera we used was the size of a cricket ball, but this obstructed the driver's vision, and so we repackaged it, and this is the design we came up with. and i think the balance of what you achieve the good outweighs the bad. and the experience is not just about what you see, it's also about what you hear. as a formula 1 cars have developed, that iconic engine has died down. steve and the team plan to rev it up once more.

it has been a long—held desire of our audio department to mount a microphone in the exhaust. how hot does it get inside the exhaust? up to 360 degrees. this is a microphone we had on lewis hamilton, and it touched the exhaust and you can see what happened to it. now it has to live outside of the bodywork. it has a heat resistance of 1000 degrees, i think. when they come to a corner and they change down, and they make that engine noise, before it wasn't very emotional. now when you listen to it, it really is a rasp. it's a really emotional sound. we have had lots of feedback from around the world, from broadcasters, and everyone loves it. even broadcasting these races is a huge operation. from australia to bahrain to china, the broadcast centre needs to be built in a matter of days to beam this race out to more than 200 countries. the most amazing thing about this broadcast centre is not

all the screens and all the technology, impressive though it is. it is the fact that at the end of the race you just fold up these desks, put a lid on it and it is already in a load of aircraft containers ready to ship to the next race. there is about 200 tonnes of equipment in this building. it takes up about two 747s and 2a trucks, effectively. how quickly can we get from one race to the next race? i think it is the biggest mobile broadcast centre in the world that moves so often. we come along, there's a concrete patch, they provide us water, and away we go. we build our whole... last sunday you finished a race, and by thursday you have come all the way to austria and you are up and running. exactly. and next thursday we will be in silverstone, fully ready...

look at the man! he's not even breaking a sweat! it's like, yeah, whatever. and actually it looks like the most stressful job this week is being done by our star in a reasonably priced, if somewhat weather—beaten, car. yes, spen, iam braving this hurricane in cologne, germany, to experience europe's most advanced weather testing centre for cars. ford have built the $108 million facility to see how it popular models fare against the most extreme conditions on earth, from altitude, humidity, winds and driving rain. there are three wind tunnels here. and capabilities of testing up to ten cars at once. i pretty much control this facility, and i conduct those tests. we have sensors for relative humidity, temperature, and for the air speed,

which is measured from differential pressure from the nozzle. first, we are going to see what it might be like to drive your car in a rainforest. it get up to 55 degrees in this room, and the humidity goes up to 95%. this is one of four temperature—controlled test chambers, complete with birdsong and fake palm trees to simulate a tropical environment. it is baking in there! that is so hot! from extreme heat to extreme cold. oh, that is the snow room. these doors are really heavy. it's about minus 17 degrees in here right now. but the temperature can be set to go as low as minus 30 degrees. minus 30 degrees, of course, is rather important for cold starts, it is important for issues for the heating system,

for comfort and for safety of course, because we have a defrosting of the windshield. they are also testing how the windshield wipers operate under heavy snow. the snow is falling from above and can test the maximum stress on part of the car. this is impressive! it is testing the weight of the snow on the car. because this is actually a realistic situation in some parts of the world, to get a big snow boulder on the...mirror! next we're going to see how cars are tested in hurricane conditions. we have climactic wind tunnels, so we always control the wind speed to simulate that the car is actually moving on the roads. so it is actually 156 km/h winds out there now. it can go up to 160 km/h. it is testing the automatic function of the windscreen wipers. whether or not there is an equal amount of time going between each blade.

the tunnel doesn't just test the rain and wind but also the effect the sun has on the car in extreme conditions. it is set up with 28 spotlights with 4000 watts bulbs to mimic sunlight. the solar system is always interesting when it comes to heat that affects our power train and performance. that really looks like being outside in the bright sunlight. it's pretty much brightens my day every time i can use it! the ability to test cars at high altitude while also simulating challenging weather conditions is the unique feature of the test centre. they can be heights of 5200 metres. engineers even have to take breaks when they are finished working in this tunnel. more than half of our vehicles are sold in markets with altitudes of more than 1000 metres. we can also simulate here pulling a trailer up the hill on different altitude levels. testing the power train regarding what is happening in terms of temperature, how that is developing and making sure that the car is safe. well, we have seen everything here and i for one am looking

forward to getting back to some nice british weather. that wasjen. and that is it from the austrian grand prix. i hope you have found it as thrilling and strange as i have. you can see a lot more photos up on twitter. thank you very much for watching and we will see you soon. hello there. i think there's a little bit of something for everyone in this forecast, some rain and also some warm sunshine. but on wednesday it was a case of high pressure, and most places

seeing some sunshine. also quite a bit of cloud around, too, but that did lead to some dramatic sunset photos sent in by our weather watchers. high pressure was the dominant force on wednesday, but we look to the north—west for a tangle of weather fronts which will bring some rain on friday. but first thing on thursday, it's going to be a dry one. variable cloud, some clear spells. quite a warm one to start the day for england and wales, but a few chilly spots across some rural parts of central northern scotland. but thursday promises to be another dry one, i think, for most. probably more sunshine around, across the board, than what we saw on wednesday. just a slim chance of a shower across north—east england and south—east scotland. and then late in the day, breeze and cloud pick up across this north—west corner, with those weather fronts. a little bit of rain here, as well. 15 to 23 degrees in the north, but as high as 28 or 29 celsius across the south—east, so it's going to be warm here. now, this is the tangle of weather fronts which will bring some rain to northern and western

parts of the uk. it will continue to move its way south—eastwards as friday wears on. so a lot more cloud across the northern half of the uk. some substantial rain in places, fairly heavy bursts at times. but as it moves southwards, it will tend to ease and become a little lighter and patchier. so it's going to be a little bit cooler across northern areas, 18 to 20 degrees. further south, though, another warm day, with temperatures reaching 28 or 29 degrees. and then, into friday evening, there is just a slim chance of seeing a thundery downpour move up from the near continent, across the south—east of england in towards east anglia. they will be very few and far between, but if you catch one, you'll certainly know about it. that cold front then continues to sink southwards during the course of saturday, so it may linger on across southern areas for a while. so we could see a fair amount of cloud central, southern england and wales on saturday, the odd spot of light rain on it.

to the north, a little bit drier, variable cloud, some spells of sunshine. temperature—wise, again the high teens celsius, mostly, across northern ireland and scotland. a bit cooler and freser as well across england and wales, 21 to 25 degrees. on sunday it's a warmer day, central and southern areas with more sunshine. further north, a bit breezier and more cloud, with outbreaks of rain. that pressure across western scotland. for the south—east, though, again mid to high 20s celsius. so it's quite a mixed weekend, with variable amounts of cloud, a little bit of rain, but also some spells of warm sunshine. welcome to bbc news, broadcasting to viewers in north america and around the globe. my name is mike embley. our top stories: making his mind up. president trump now says vladimir putin is to blame for russia meddling in the us election. well, iwould, because he's in charge of the country, just like i consider myself to be responsible for things that happen in this country. so certainly, as the leader

of a country, you would have to hold him responsible, yes. the thai cave boys finally go home, after telling the world's media how it felt to be rescued. google is fined a record sum by the european union, almost $5 billion, over its android operating system. and, from the arctic circle to the baltic sea, sweden calls for international help as it battles to contain at least a0 wildfires.
