this is bbc news. here are the headlines: donald trump is celebrating the strongest us economic growth in four years, despite warnings it might not last. the increase of 4% between april and june was driven by strong consumer spending and a surge in exports. the president has described the figures as historic. millions of people are gazing skywards to catch the longest lunar eclipse this century. it's as the moon passes through earth's shadow. the blood moon occurs when the earth's natural satellite appears as shades of red, when the sun is filtered through the atmosphere. a sexual misconduct investigation has been launched at cbs, one of the big us tv networks. claims going back several decades have been made against the broadcaster's chairman and chief executive, leslie moonves. now on bbc news, it's time for click. this week, the green delyn. deep

blue sea. and that yellowjersey. —— the green dome. the eight planets in our solar system, all unique and instantly recognisable. and don't they look amazing from our viewing protean here in outerspace? now what we really won't showy is just how good visual have become. not only does the graphics computer generate all of these lovely images but as the cameras move about, the objects in the background —— and the background

appear to stay in their correct positions. now this is not easy, now this technology originally came from the movies and now it has come to tv. so, here we are in the bbc‘s virtual studio in the first thing he will notice is that obviously the graphics computer replaces anything thatis graphics computer replaces anything that is green with the background. art, in order to draw all of the objects in the right place in 3—d space, the computer needs to know exactly where the cameras are so it can draw everything from the right angle, and that is why all the cameras have this set off reflective tracking ball is on top of them. it also means that i can take my own set of tracking balls and turn this into a virtual hand—held camera that ican into a virtual hand—held camera that i can fly to the sea. so, there is mercury and venus, earth and mars, coming round par stupider, just up under saturn and there is your nurse and neptune. and here is the thing,

just as we are getting used to having this much fun in tv studio, at the top end of the movie industry they are getting ready to something even more incredible. —— uranus. he is mark cieslak in los angeles. the next big leap in cinema technology could be upon us. called intel studios, this is the first time a crew has been allowed to even catch a glimpse behind the scenes at the state—of—the—art equipment. this baseis state—of—the—art equipment. this base is designed to film in 360 degrees, a technique known as volumetric capture. de jager has worked on the visual effects in movies like gravity and warhorse. now he is heading up this operation. so this is your volumetric space. now he is heading up this operation. so this is your volumetric spacem is indeed. it is pretty big. is the largest one in the world. it is currently focused on large—scale volumetric capture, and it is a

unique space that we have built, dedicated for filmmaking volley metric. can we take a look inside your dome, please? that is a lot of green. that is a lot of green. it is a lot of space and a lot of cameras. how many a lot of space and a lot of cameras. how many cameras a lot of space and a lot of cameras. how many cameras have you got here? well, currently have we have more than 100 cameras. how do you have enough senses to capture the information from any angle? so you can see around, it is really a variation of angles and positions that we used to capture anything from every position. in this space, a scene can be recorded once but is recorded on all of those cameras surrounding actors, so every single act angle is covered. the volumetric shots are pumped the service, which then processed these into a cloud. this is a 3—d representation of the

entire studio. the action can then be watched from any angle that your desires. 0nce decisions have been made about where to position the camera, the action is queued up. this particular scene was made several times. you can create virtual sets and integrate performance around that but the key thing is you can keep my performance, you can keep a presence that the actors have, the interaction between them, and once you have digitiser information, once you have digitiser information, once you basically generated this volumetric, immersive data, it can really be walking in cyberspace and reshoot the entire sing again. the building process, with its 100 plus cameras orfilming building process, with its 100 plus cameras or filming at once, generates a massive amount of data, all of which is processed and stitched together on—site. in total,

there are 10p to bytes of storage in here. that is the equivalent of 133 yea rs of here. that is the equivalent of 133 years of film. because the dome separates the studio from the crew filming, directing is similarto filming, directing is similarto filming ina filming, directing is similarto filming in a new studio. so once it is no motion captured things, it is here, and that would be the performance. -- petabytes. only am used to working with cameras, it is going to be difficult to work with over 100 of them. i am going to

attempt to get this ball into that group. that's tried again. this time, the team had backgrounds and create a seamless shot from the 100 individual captures. and the crowd goes wild. creating the shot is not quick though, this one took about 150 hours to make. as we look at filmmaking, we want to create that, that transition. how do you immerse into this world and into these experiences, but would be like this, with the real performance? —— but with the real performance? —— but with the real actors. hello and welcome to the week in tech. it was the week that facebook sense of new paintings from a flemish master. an underground lake of liquid water was discovered on mars. and here on

earth, walmart discovered a new delivery service in partnership with google. it was also the week that a tea m google. it was also the week that a team of german engineering students hit a new hyperspeed record a57 kilometres per hour. the team from munich beat the record set last year by 50%. the new scanners for carry on luggage which could put an end to the ban on liquids in carry on baggage. the technology can see inside the back seat do not have to ta ke inside the back seat do not have to take out your liquid is or technology separately. the country's health minister wants to monitor sales. the drug will be legalised in canada in october next year. the popular game cards against humanity launched an unusual online dating sites this week where you can date and infiltrate so—called members of the islamic state. the creator of

the islamic state. the creator of the game session once the game to dismantle racial stereotypes. finally, this looks like fun but a new product from the company segway will be banned. under the uk highways act of 1835, they are classified as carriages and are to be banned. no, aliens had not landed on earth. this is london's royal albert hall, which became a giant canvas for an amazing night show to start the bbc proms. powered by 20 laser projectors, it took the team about a week to set up outside. called 1a to 18 now, it is set to music composed by anne meret is, inspired by the mitigation methods used in world war i. we found five movements, one,

two, three, four, five, and a rough movement. but nothing really musical, just shapes. —— meredith. creating the shapes to match was the work of the project, who illustrated telegrams sent by soldiers and even code breaking. this is where the tea m code breaking. this is where the team practices that projections. they create these tiny models of real—life buildings. instead of using ten or 20 projectors, here they using just create the images on they using just create the images on the building. it is incredible. the process for us the building. it is incredible. the process for us was the building. it is incredible. the process for us was to go to edinburgh, a laser scanner that square in that building to do an accurate 3—d model. we take that model, we use that for our animation. 0bviously model, we use that for our animation. obviously the last stage of the project, we see things on a model because it gives you a sense of how things move around corners and how things feel. 59 productions

have previously created the light shows with the guggenheim museum in new york on the sydney opera house, but its next project is going to focus on the sound of minutes of silence in a dark room with no light at all. we would like to try and do things that are quite different, i suppose, so sometimes it is huge scale and colour and the crowds, and sometimes it is silence in small museum. the next chance to see it this is at the edinburgh festival on august three. —— to see this. that wasjen at august three. —— to see this. that was jen at the royal albert august three. —— to see this. that wasjen at the royal albert hall. now, the tour de france is coming to an end this week, the monumental 3351 kilometre race is now 115 years old. fans love its epic proportions and its gruelling pace, but this year they may also be able to enjoy a lots and lots of lovely data.

because analytics and machine learning are coming to one of the old est learning are coming to one of the oldest sporting competitions in the world, and pat hawkins went to find out how. this he's tour de france is taking place against the same beautiful french mountains as always. —— kat. cycling is becoming increasingly data driven and the good reason. masses of data can be collected and in the sport of fine margins and superhuman insurance, those insights are the key to energy efficiency, strategy and gains. we look at many things, we look at obviously heart rate, power data and their maximum power and their altitude and elevation gain. so we look at that and we see how the riders are building and we leveraged that darted to try and build them to be stronger and better in stage

races. how is the data collected and transmitted? races. how is the data collected and transmitted ? that races. how is the data collected and transmitted? that is where these little devices come in. they may not look like much but this small devices on the back of every bike taking place in the two and it has actually been revolutionary. —— it may not. it then beams up to a following helicopter. it is then sent to the data truck real—time analytics. and this is where the magic happens, from bike to motorbike the helicopter to hear, this is where all the data from the tour de france is being stored. the data truck is where data is analysed, and rich, and visualise the broadcasters and team. there is even enough data per machine learning algorithms to get to work. the depths of data analytics produced from simply a gps device is staggering. conceptual data such as 3-d staggering. conceptual data such as 3—d maps, weather, gradients and right information is also added to bring the data to live. during the race, riders wear earpieces and

following closely behind them is the data park, where the team analyst is analysing the data and feeding them live information. is what happens in him? it is quite an important place, isn't it? if you imagine you are at nasa and trying to buy a rocket to the moon, when all the details come in and they can be from all directions, and we send out one message to the riders. hundreds of datasets are analysed, from competitor tactics to live course condition. so we analyse all of the climbs, the gradients of the climbs, the road surfaces, the wit to the roads. if they are coming around the blind corner and there is a pedestrian crossing, all of these things we try to identify. the tour de france with restrictions and sponsorship deals, we do not get any heart rate and power data, but we do get location, which is absolutely crucial because we can make decisions much, much quicker. ok, so we in the race. this is happening,

this is live. are we saying to our riders? so, come on, you have got 250 more metres. round the next corner here, hairpin. can't see the flattens off. you will have jinks in aoo flattens off. you will have jinks in 400 metres, is he will get to cool down. have jinks and go to the finish. good luck. i can see insta ntly that finish. good luck. i can see instantly that the psychological impact of that is huge, but how do the cyclist themselves feel about having data in their sport? having everything measured and tract can have its downsides. you try to keep it secret because when you are racing the tour de france you don't really wa nt racing the tour de france you don't really want to give your competitors that advantage. people say it is turning to f1, it isjust that advantage. people say it is turning to f1, it is just robots talking to robots. what do you say to those people? it is more than that. a robot doesn't have to put the effort in. biometric data isn't actually transmitted live, but that

isn't because of technical limitations. the data ownership tween the rider, the teams, the race owners, is still quite complex. —— in between. so at the moment the data we have permission to collect and publish is positioning data which tells a story is about speed, gradient and permission. it is possible to take biometric data and we have actually piloted that at the tour of california a couple of years ago and also in a stadium environment. but for the teams it is very sensitive because biometric data also gives great competitive insight into how hard that rider is working to perform the way they are doing. as well as sponsoring their own team, damage and data is the technology company behind all the data collected for the tour de france. their technology has managed to ove rco m e france. their technology has managed to overcome problems unique to this epic race. they have been studying this tracking system for 15 years, 20 years. the big thing we have to deal with is that we are in the middle of nowhere, in the middle of the montaigne, the weather

conditions can be terrific sometimes. so this is the main thing, to be able, logistically speaking, to track every day and give information in real—time. that is the most complicated thing. from data centre to road race, there is 20 kilometres to go, 20 kilometre wind speeds. the final is coming up. that was catwalk and set the tour de france. now, ican that was catwalk and set the tour de france. now, i can guarantee you none of those riders had a bike frame anything like this. not only is this incredibly light, just 600 g, but it is loaded with technology. and it is being developed here enrolling wouldn't, just by the duckpond. —— here in rural england. yes, just past the hartney whitney village green in a converted cow barn, an ex— rolls—royce aerodynamicists designed this revolutionary new frame. stuart abbott has embedded sensors inside

it which sends live data into the cloud to be analysed by cycling teams or casual cyclists alike. an accelerometer in the rear chain stay. also, to bridge the pressure and humidity. —— temperature pressure. the frame is made in a mould like this from many layers of this carbon composite. but on to one layer of the composite, they print the circuitry for the senses and the conduct of pathways which sends the data around the frame. all of this is made from graf ian. we have connected the senses using graphene — printed circuitry. i know peter patrick, the committee, the air pressure, the amount of what's you are pushing. i know how much you are deforming the frame, i know the headwind and the tailwind. i pulling all of that together, i can say you should stop. and in the future you wa nt to should stop. and in the future you want to exploit other properties of

graphene to do something pretty incredible to this frame? yeah, we wa nt to incredible to this frame? yeah, we want to actually be able to change the shape of the frame dynamically, based upon the environmental conditions that are there at the time. so while you are writing, your bike could change shape? time. so while you are writing, your bike could change shape7m time. so while you are writing, your bike could change shape? it won't be as much as optimist prime or that kind of thing, but while you are riding, you may well have positioned intelligent materials over the frame that cause it to change shape to improve the aerodynamic efficiency. i tell you, the idea of pedalling ha rd i tell you, the idea of pedalling hard in this heatwave, not for me. but of course, for many, working for hours on end in the baking sun is just part for the course, and that includes the australian wildlife services. now, at the moment, they are working to protect a very special part of the great barrier reef. nick has been to meet the rangers who are really working up a sweat. reed islands, the great barrier

reef. nesting ground to the world's largest collection of green turtles. each year 60,000 of these endangered creatures migrate here to give birth. but their population is in decline. —— population. so the wildlife services at the great barrier reef foundation have upped their game. it is about intervening. we are actively going in and doing things at the island, we are moving sand around with machines, rescuing turtles, putting up fences. we are using and embracing technology and thatis using and embracing technology and that is a big mind shift from how parks have been managed in the past. raine island is unique in that it has a torres strait islander traditional owner and an aboriginal mainland traditional group. for jimmy and peter, their connection with raine island stretches far into their ancestral past. it is best us to get involved using the technology, so we can help the parks and wildlife rangers. turtles need,

you know, good conditions. the whole world needs that, you know? to look after this place that we call home, you know? to get to raine island, it is quite a mission. it takes our boat, which does 18 knots, about two to four hours straight from cairns. —— 2a hours. a very remote island. 16 of us go over. we sleep on the boat during the day, generally, and to the total work at night, 12 hour shifts at least. the island is so remove the team can only visit a queue times per year. we satellite tag turtles. it's got very good gps data. we can look at how often the total comes up, how often she spends on the beach at night, whether she comes back the next night. so we know whether she nested successfully, we can track over the whole season how many attempts she made too late, and hamley times she laid successfully, which is really important information for us. —— how many times. tina's team also do a

visual account, including egg good old bucket of paint and a quicker. —— a good old. old bucket of paint and a quicker. -- a good old. we paint them, they go back to see, the next few days we do what is called a painted turtle camp. it is a manual process that ta kes camp. it is a manual process that takes ages from the back of the boat. the last two seasons we have trialled using a drone. it takes 15 minutes or so to do. beautiful shots as well. the white snapshot captured from the drone makes counting much faster and more reliable. the eye in the sky is help ring monitor rare seabirds more effectively as well. anything that help suss monitor raine island when we are not there is great. we use from eight cameras for that now. -- remote cameras. they have installed a broadband network to being the pictures back to base. i can sit in my computer in my office and log on to raine island and see how many turtles come in at

night. 90% of the northern great barrier reef‘s green turtles nest at raine island. if that population colla pses, raine island. if that population collapses, that is most of the turtles in the northern great barrier reef, the torrid straight, around to the gulf of carpentaria, about a whiter, the solomon islands. 0ur turtles are not just about a whiter, the solomon islands. 0ur turtles are notjust our turtles at raine island. they migrate all around the northern region. the population collapsing would have massive impacts on those committees. and these native communities i'd doing what they can to help. today they are getting their boating licence, training from the parks and wildlife service. for us to be out here because of our history that we have with raine island, trading wise, our ancestors used to go all over. we have that connection now today to raine island. we have that history and songs. they use the ipad is, we have a total database and all the total monitoring is done on that. they also get involved with

helping out with the drone work and the survey in. it would be good to learn a lot more. because we are living in a modern world and we've got to keep up. not too many old people left. we are the next one is in line, so we've got to learn as much as we can so in line, so we've got to learn as much as we can so we can pass in line, so we've got to learn as much as we can so we can pass it down to our kids and their kids can pass it down to their kids. indigenous and nonindigenous, we'll to work together. —— we all have to do. i am truly privileged to have thisjob and do. i am truly privileged to have this job and get to go to raine island, which is an incredibly unique place. and, yeah, it does bring a bit of a tear to your eye when you see your first turtle laying her first clutch of eggs in front of you, or a total that you rescued. it gives you a nice, fuzzy feeling. —— turtle. rescued. it gives you a nice, fuzzy feeling. -- turtle. how brilliant is that? that was nick kwek in australia. that is all from us this week. don't forget, you can follow us on week. don't forget, you can follow us on twitter and on facebook as

well, where you'll find loads of extra tech news and behind—the—scenes photos through the week. thanks for watching, and we'll see you soon. hello there. violent thunderstorms broke out across southern and central parts of the country late on friday. this marks the end of the current heatwave. the thunderstorms continued to clear northwards and eastwards and then things turn cooler, with showers following on behind. that is the culprit for the change to our weather, the big area of low pressure that has been moving in off the atlantic. you see the thunderstorms, a line of them across east anglia and into england and eastern scotland. as we head into the early hours of saturday, most of the thunderstorms will clear off into the north sea. they could, however, mingle on a bit longer into the north—east of scotland. behind those, further pulses of rain pushing in to start saturday morning. it is going to be slightly cooler and fresher here but for england and wales, again, another warm and humid night.

saturday, we start off with showery rain, maybe some of the country. quite a wet start for north—east scotland. some of these producing longer spells of rain in northern ireland. could be even heavier thunder across england and into the west of wales. this is something we have not seen for a while, blustery winds. i have got the wind areas on here because it is going to be quite gusty, 20 to a0 miles an hour in some places. it is going to be a lot cooler and fresher to what we have been used to. 10 degrees cooler now than what we saw thursday and friday. the low pressure is still with us as we head into part two of the weekend. in fact, this feature running up in the south—western parts of england could bring a spell of storms. windier and cooler pretty much across the board. some of this rain will be pretty heavy and prolonged, good news for gardeners and growers, as it continues to push its way northwards into much of scotland. behind that, we could see a few sunny breaks, but it is going to be another windy day, particularly across england and wales, and even fresher on saturday, temperatures at best 21 or 22 across southern areas. closer to the high teens celsius further north. yes, it is going to be a cool, fresh week, with some strong outbreaks of rain. the signs are as we head

into the new working week, high—pressure continues to push in and these temperatures are going to be on the rise again. some of this rain will be heavy and prolonged. that is good news for gardeners and growers. it continues to push its way north, into much of scotland. behind it we could see a few breaks but it is going to be another windy day, particularly across england and wales, and even fresher than saturday. 21 or 22 across southern areas. it is going to bea across southern areas. it is going to be a cool and fresh weekend with strong winds at times and outbreaks of rain. signs are that as we had deeper on into the new working week, high pressure begins to build. it looks like those temperatures will

be on the rise again. welcome to bbc news — broadcasting to viewers in north america and around the globe. i'm duncan golestani. our top stories: donald trump celebrates the strongest us economic growth in four years, despite warnings it might not last. the president takes credit for putting america first. we are the economic envy of the entire world. when i meet the leaders of countries, the first thing they say invariably, is "mr president, so nice to meet you, congratulations on your economy". a spectacular night sky show for millions, as a blood moon rises in the longest lunar eclipse this century. the cbs television network investigates allegations of sexual misconduct against its top executive.
