areas on sunday and and coastal areas on sunday and through the afternoon, with gusts of 40-50, through the afternoon, with gusts of 40—50, and you can see the rain sweeping north and east across the country. a fresher datamirror still, around the high teens —— a fresher day tomorrow still. hello, this is bbc news, with chris rogers. the headlines: travel disruption at airports, on the roads and at eurotunnel, as the recent weather continues to cause problems. some ryanair flights from stansted have been cancelled. mps have warned british democracy is in crisis — because of targeted campaigns of hate and misinformation on social media. the chief constable of the west midlands admits his force is, at times, providing a poor service because of busget cuts — and apologises the cast for the next star wars film is revealed, and it will include previously unseen footage of the late actress carrie fisher.

and australian sailor wendy tuck has become the first female skipper to ever win the clipper round the world yacht race. we will have more on those stories at the top of the hour. now on bbc news, it's time for click. this week, big green dome. deep blue sea. and that yellow jersey. the eight planets in our solar system, all unique and instantly recognisable. and don't they look amazing from our viewing platform here in outer space? now, what we really wanted to show

you is just how good the visuals 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 appear to stay in their correct positions. now, this is not easy. this technology originally came from the movies and now it has come to tv. so, here we are in the bbc‘s virtual studio, and the first thing you will notice is that obviously, the graphics computer replaces anything that's green with the background. but 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's why all the cameras have this set of reflective tracking balls 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 i can fly through the sea.

so, there is mercury and venus, earth and mars, coming round jupiter, just up under saturn, and there is uranus and neptune. and here's the thing, just as we're getting used to having this much fun in a tv studio, at the top end of the movie industry, they're getting ready for something even more incredible. here's mark cieslak, in los angeles. the next big leap in cinematic 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 of this state—of—the—art equipment. this space is designed to film in 360 degrees, a technique known as volumetric capture. diego has worked on the visual effects for movies like gravity and warhorse. now he's heading up this operation. wow, so, this is your

volumetric space? it is indeed. it's pretty big. it is the largest currently 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 volumetric. can we take a look inside your dome, please? wowee! that's a lot of green! that's a lot of green. it is a lot of space and a lot of cameras. how many cameras have you got here? well, currently, we have more than 100 cameras. how do you have enough sensors to capture the information from any angle? so, as you can see around, it's really a variation of angles and positions that we use to capture anything from every position. in this space, a scene can be recorded once, but is recorded on all of those cameras surrounding the actors,

so every single angle is covered. the individual shots are pumped to the service which then processes these into the point cloud. this is a 3—d representation of the entire studio. the action can then be watched from any angle the viewer desires. once decisions have been made about where to position the camera, the action is cued up. this particular scene was made several times. the shots were all captured on the 15th attempt. you can create virtual sets and integrate performance around that, but the key thing is, you can keep performance, you can keep the presence that the actors have, the interaction between them, and once you have digitised the information, once you have basically generated this volumetric, immersive data, you can really be walking in the space

and reshoot the entire thing again. the filming process, with its 100—plus cameras all filming at once, generates a massive amount of data, all of which is processed and stitched together on—site. in total, there are 10 petabytes of storage in here. that's the equivalent of 133 years of film. paramount pictures have penned a deal to use this space for upcoming projects. because the dome separates the studio from the crew filming, directing is similar to directing in a new studio. so no motion captured things, it is you that will be the performance.

i'm used to working with cameras, but it is going to be difficult to work with over 100 of them. i'm going to attempt to get this ball into that hoop. let's try that again. this time, the team has backgrounds and creates a seamless shot from the 100 individual captures. and the crowd goes wild! creating this 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 with the real actors, with the real performance? hello and welcome to the week in tech.

it was the week that facebook censored new facebook censored nude paintings from flemish master rubens. an underground lake of liquid water was discovered on mars. and here on earth, walmart discovered a new delivery service in partnership with google‘s waymo. it was also the week that a team of german engineering students hit a new hyperspeed record of a57 kilometres per hour. the team from munich beat the record set last year by 50%. heathrow and jfk airport began testing... 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 bag, so you do not have to take out your liquids 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 party game cards against humanity launched an unusual online dating site this week, where you can date and infiltrate members of the so—called islamic state. the creator of the game says she wants the game to push boundaries and dismantle racial stereotypes. finally, this looks like fun, but a new roller—shoe from the company segway will be banned. under the uk highways act of 1835, they are classified as carriages and are to be banned on the pavement. no, aliens haven't landed on earth. this is london's royal albert hall, which became a giant canvas for an amazing light show to start the bbc proms. powered by 20 laser projectors, it took the team a week

to set up outside the hall. called 1a to 18 now, it is set to music composed by anne meredith, inspired by communication 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. creating the shapes to match the music was of 59 productions, who illustrated telegrams sent by soldiers and even code breaking. this is where the team practices the projections. they create these tiny models of real—life buildings. instead of using ten or 20 projectors, here they use just two to create the images on the building. it's incredible. the process for us was to go

to edinburgh, get a laser scan that is square in that building to do an accurate 3—d model. we take that 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 light shows for the guggenheim museum in new york, and 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 like to try and do things that are quite different, so sometimes, it is huge scale. and sometimes, it is silence in a small museum. the next chance to see this is at the edinburgh festival on august 3rd. that was jen at the royal albert hall. now, the tour de france is coming

to an end this week. the monumental 3,351 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 lots and lots of lovely data, because analytics and machine learning are coming to one of the oldest sporting competitions in the world, and kat hawkins went to find out how. this year's tour de france is taking place against the same beautiful french mountains as always. but there is a big difference this year, technology and state it is playing more of a role than ever before. cycling is becoming increasingly data driven and for good reason. masses of data can be collected, and in a sport of fine margins and superhuman endurance, 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 leverage that data to try and build them to be stronger and better in stage races. but how is the data collected and transmitted ? that's where these little devices come in. it may not look like much, but this small clip—on device is on the back of every bike taking place in the tour this year and it has actually been revolutionary. it then beams up to a following helicopter. it's then sent to the data truck for real—time analytics. and this is where the magic happens. from bike to motorbike, helicopter to here, this is where all the data from the tour de france is being stored. the data truck is where data is analysed, enriched, and visualised for broadcasters and teams. there is even enough data for machine—learning algorithms to get to work.

the depth of data analytics produced from simply a gps device is staggering. conceptual data such as 3—d maps, weather, gradient, and rider information is also added to bring the data to life. during the race, riders wear earpieces. and following closely behind them is the data car, where the team analyst is analysing the data and feeding them live information. what happens in here? it is quite an important place, isn't it? if you imagine you have a comms office. flying to the moon. you're 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 width of the roads.

if they are coming around a blind corner and there is a pedestrian crossing, all of these things we try to identify. 0n the tour de france, with restrictions and sponsorship deals, we don't 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're in the race. this is happening, this is live. what are we saying to our riders? so, come on, serge, you have got 250 more metres. round the next corner, it's a hairpin. you can't see it, but it flattens off. you will have drinks in 400 metres, so you will get to cool down. have drinks and go to the finish. we only have 10k to the finish. good luck. i can see instantly that the psychological impact of that is huge, but how do the cyclists themselves feel about having data in their sport? having everything measured and tracked can have its downsides. teams are trying to to keep it secret because when you're racing the tour de france, you don't really want to give your competitors

that advantage. people say, oh, it's turning into f1, it'sjust robots talking to robots. what do you say to those people? it's 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 between the rider, the teams, the race owners, is still quite complex. so, at the moment, the data we have permission to collect and publish is positioning data which tells a story about speed, gradient and positioning. 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's very sensitive because that biometric data also gives great competitive insight into how hard that rider is working to perform in the way they are doing. as well as sponsoring their own team, dimension data is the technology company behind all the data collected for the tour de france. their technology has managed

to overcome problems unique to this epic race. they've been studying this tracking system for 15 years, 20 years. the big thing we have to deal with is that we're in the middle of nowhere, in the middle of the mountains, the weather conditions can be horrific 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's 20 kilometres to go, 20—kilometre wind speeds. the final‘s coming up. that was cat, reporting from the tour de france. now, i can guarantee you that none of those riders had a bike frame anything like this. not only is this incredibly light, just 600 grams, but it is loaded with technology. and it's being developed here in rural england, just by the duckpond. yep, just past the hartney whitney

village green, in a converted cow barn, an ex—rolls—royce aerodynamicist designed this revolutionary new frame. stuart abbott has embedded sensors inside it, which send live data into the cloud to be analysed by cycling teams or casual cyclists alike. there is an accelerometer in the rear chain stay. also, temperature, pressure and humidity. the frame is made in a mould like this from many layers of this carbon composite. but onto one layer of the composite, they print the circuitry for the sensors and the conductive pathways which send the data around the frame. all of this is made from graphene. we have connected the sensors using graphene—printed circuitry. i know the temperature,

the humidity, the air pressure, the amount of watts you're pushing. i know how much you are deforming the frame, i know the headwind and the tailwind. pulling all of that together, i can say, you should stop. and in the future, you want to exploit other properties of graphene, to do something pretty 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're riding, your bike could change shape? it won't be as much as 0ptimus prime or that kind of thing, but while you're 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 hard in this heatwave, not for me. but of course, for many, working for hours on end in the baking sun isjust par for the course, and that includes the australian wildlife services.

now, at the moment, they're working to protect a very special part of the great barrier reef. nick kwek has been to meet the rangers who are really working up a sweat. raine island, 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. so the wildlife services at the great barrier reef foundation have upped their game. it's about intervening. we're actively going in and doing things at raine, we're moving sand around with machines, rescuing turtles, putting up fences. we're using and embracing technology and that's a big mind shift from how parks have been managed in the past. so, raine island is unique in that it has a torres strait islander traditional owner group and an aboriginal mainland

traditional group. forjimmy and peter, their connection with raine island stretches far into their ancestral past. it's best for 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's quite a mission. it takes our boat, which does 18 knots, about 2k hours straight from cairns. a very remote island. 16 of us go over. we sleep on the boat during the day, generally, and do the turtle work at night, 12—hour shifts at least. the island is so remote, the team can only visit a few times per year. we satellite—tag turtles. it's got very good gps data. we can look at how often the turtle comes up, how long she spends on the beach at night,

whether she comes back the next night. so we know whether she nested successfully, so we can track over the whole season how many attempts she made to lay, and how many times she laid successfully, which is really important information for us. tina's team also do a visual count, including a good old bucket of paint and a clicker. we paint them, they go back out to sea, the next few days, we do what's called a painted turtle count. it's a manual process that takes ages from the back of the boat. the last two seasons, we have trialed using a drone. it takes 15 minutes or so to do. beautiful shots, as well. the wide snapshot captured from the drone makes counting much faster and more reliable. the eye in the sky is helping them monitor rare seabirds more effectively too. anything that helps us monitor raine island when we're not

there is great. we use remote cameras for that now. they have installed a broadband network to beam the pictures back to base. so, i can sit at 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 green turtles nest at raine. if that population collapses, that's most of the turtles in the northern great barrier reef, the torres strait, around to the gulf, to vanuatu, the solomon islands. so, our turtles are not just our turtles at raine. they migrate all around the northern region. so, the population collapsing would have massive impacts on those committees. and these native communities are doing what they can to help. today, they're 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, trading—wise, our ancestors used to go all over.

we have that connection now today to raine island. we have that history, and songs, and whatever. they use the ipads, we have a turtle database and all the turtle monitoring is done on that. they also get involved with helping out with the drone work and the surveying. it would be good to learn a lot more. because we're living in a modern world and we've got to keep up. not too many old people left. we're the next ones 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 non—indigenous, we all have to work together. 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 turtle that you rescued. it gives you a nice, fuzzy feeling.

how brilliant is that? that was nick kwek, in australia. that's all from us this 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. what a change to the weather in the last 25, especially across east anglia and the south east. a 10 degrees drop and thunderstorms and a lot fresher across the whole country. blustery showers and very heavy rain at the northern ireland

and an amberwarning heavy rain at the northern ireland and an amber warning in force for northern ireland this afternoon. check your local weather, it may affect your plans. this weather system brought the fresher weather, this is heading our way wringing wet and windy weather tonight and tomorrow into the south—west. this is the jet stream and behind that, a shot of cold air out of the north atlantic. this is the amber warning for northern ireland from the met 0ffice. for northern ireland from the met office. a lot of rainfall to come this afternoon. not everywhere, but be prepared for some local flooding. for the rest of today and into the evening, further showers. the winds will pick up across the south—west, in south—western england, wales, the north west of england by the end of the night. eastern areas should stay dry and the loans of scotland and perhaps northern ireland in between these two weather systems. —— the highlands. blustery day on sunday, an area of low pressure here of the

western isles of scotland. windy weather in the western isles and towards the south—west. in the south—west, gales of 40—50 mph, bad news barrett holiday—makers, and the rain drips to the north and east. most of those catching some rain tomorrow and the brecon beacons could be a lot, 50 millilitres. a couple pockets around the uk, north west of scotland and northern ireland, not a bad day with sunshine. it is cold everybody, relatively speaking, temperatures to polygamy in the high teens or 20s celsius. —— temperatures typically. high pressure across the atlantic on monday, where the air is coming from, quite breezy, so no more air coming from the continent, it is coming from the continent, it is coming off the ocean, but it is warming upa coming off the ocean, but it is warming up a bit with southern parts of the uk not quite so fresh. but overall, for the week ahead, it is a relatively fresh start with showers,

but gradually warming up towards the end of the week. this is bbc news. i'm chris rogers. the headlines at 11... travel disruption at airports, on the roads and in the eurotunnel, as the recent heatwave continues to cause problems. some ryanair flights from stansted have been cancelled. mps warn british democracy is in crisis because of targeted campaigns of hate and misinformation on social media. the chief constable of the west midlands admits his police force is occasionally providing a poor service, and apologises. we are incredibly busy at this time. the level of calls we receive in the summer is very challenging. sometimes that service we provide in the peak times doesn't meet the service people expect. also coming up... australian sailor wendy tuck has become the first female skipper to ever win the clipper round of the world yacht race. thousands watched her team lift the trophy in liverpool, nearly a year after they set out from the city.
