the headlines — at least five people have died, including two children and their great—grandmother, as a huge wildfire sweeps across northern california. 17 people are missing and nearly forty thousand have been forced to flee. firefighters are battling the blaze. they say it's only 5% contained so far. the two main candidates in zimba bwe‘s presidential elections have addressed large crowds of supporters in the capital, harare. president emmerson mnangagwa of the zanu—pf party faces a challenge nelson chamisa of the opposition mdc. it's the first presidential poll since robert mugabe was ousted from power in november, pope francis has accepted the resignation of a prominent us cardinal. the catholic church found that allegations theodore mccarrick had sexually abused a teenager were "credible and substantiated". now on bbc news, click. this week, the 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 won't show you is just how good 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 obviously that the graphics computer replaces anything that is 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 is 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 to 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 are 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 is 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 at the state—of—the—art equipment. this base is designed to film in 360 degrees, a technique known as volumetric capture. diego 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. it is indeed. it is pretty big. it 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 volumetric. can we take a look inside your dome, please? wow, that's a lot of green. that is a lot of green. it is 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. our goal is, how do you have enough sensors 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 the actors, so every single angle is covered. the individual shots are pumped to the service which then processes these into the cloud.

this is a 3—d representation of the entire studio. the action can then be watched from any angle that your heart desires. once decisions have been made about where to position the camera, the action is cued 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 that live 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, it can really be walking in cyberspace 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 is the equivalent of 133 years of film. paramount pictures have penned a deal. because the dome separates the studio from the crew filming, directing is similar to filming in a modern news studio. so no suits, no motion captured things, it is here, and that would be the performance. this is my opportunity to try out this volumetric studio. i am used to working with cameras, but it is going to be difficult to work with over 100 of them. they will be able to capture from every single conceivable angle. i am going to attempt to get

this ball into that net. let's try that 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 with the real actions, with the real performance? hello and welcome to the week in tech. it was the week that facebook censored new paintings from a flemish master, rubens. an underground lake of liquid water was discovered on mars.

and here on earth, walmart announced a new delivery service in partnership with google‘s waymo. it was also the week that a team of german engineering students set a new hyperlink speed record of a57 kilometres per hour. the team from munich beat the record set last year by 50%. heathrow and jfk airports tried out... 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 separately. blocked an technology is keeping record of cannabis sales in canada. the country's health minister wants to monitor sales while keeping users‘ data private. the drug will be legalised in canada in october next year. the popular 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 american creator of the game says she wants the game to dismantle racial stereotypes. finally, this looks like fun, but a new product from the company segway will be banned in the uk. under the uk highways act of 1835, they are classified as carriages and are to be banned. no, aliens have 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 anna meredith, 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. 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 team practices the projections. they create these tiny 3d printed models of real—life buildings. instead of using ten or 20 projectors, here they usually just two to create the images on 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. obviously the last stage of the project, we see things on a model because it gives you a sense of how content moves around corners

and how things feel. 59 productions have previously created the light shows with 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, i suppose, so sometimes it is huge scale and colour and the crowds, and sometimes it is intimate and small in museums. the next chance to see this is at the edinburgh festival on august three. that was jen 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 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 is playing a big role. cycling is becoming increasingly data driven and for good reason. masses of data can be collected and in the 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 is 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 is then sent to the data truck for real—time analytics. and this is where the magic happens. from bike to motorbike to helicopter to here, this is where all the data for 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 depths of data analytics produced from simply a gps device is staggering. contextual 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 truck, 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, at nasa, the details come m, in, 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. any road furniture. anything coming around a blind corner. 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 are in the race. this is happening, this is live. what are we saying to our riders? so, come on, you have got 250 more metres. round the next corner here, it's a hairpin. you won'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. good luck. i can see instantly that the psychological impact of that is huge, but how do the cyclists themselves feel about data in their sport? having everything measured and tracked can have its downside. a lot of teams are trying to keep it a secret. when you're racing the tour de france you don't really want to give your competitors that advantage. people say it's turning into f1, it'sjust robots talking to robots. what do you say to those people? it's more than that, you know? 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 us stories about speed, gradient and position. 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 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, 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 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 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 is 20 kilometres to go, 20 kilometre wind speeds. the final is coming up. that was cat hawkins, reporting from 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 grams, but it's loaded with technology. and it's being developed here in rural england, just by the duckpond. yes, just past the hartney whitney village green in a converted cow barn, an ex—rolls—royce aerodynamicist has 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, temperature, pressure and humidity. the frame is made in a mould like this from many layers of this carbon composite. but on 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 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. and by 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 are riding, your bike could change shape? it won't be as much as 0ptimus 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 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 are actively going in and doing things at raine, we are moving sand around with machines, rescuing turtles, putting up fences. we are 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 group and an aboriginal mainland traditional group. forjimmy and peter, their connection with raine island stretches far into their ancestral past. it is 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 is 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 to 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 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 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 to sea, the next few days we do what's called a painted turtle count. 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 snapshots captured from the drone makes counting much faster and more reliable. the eye in the sky is helping monitor rare seabirds more effectively as well. anything that helps us monitor raine island when we are not there is great. we use remote cameras for that now. they have installed a broadband network to beam 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 collapses, that is most of the turtles in the northern great barrier reef, the torres strait, around to the gulf, vanuatu, 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 are 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 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 are 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. good morning. not only was yesterday our first day below 25 degrees sincejune 23, it was also for some an especially wet one, flooding in northern ireland as we saw a months worth of rainfall in just three hours. bringing about the change has been been a shift in the position of the jetstream. instead of being to the north of us, it's taken a dive southwards across the atlantic and pushed towards the south, circulating an area of low pressure around the uk and dragging in cool air off the north atlantic. it has two discrete centres, one to the north—west of scotland, very strong winds, and one to the south of england. again, some strong winds to come.

accompanied by a spell of steady rain, not the intensity we saw on saturday. the big story will be the strength of the wind. 40, 50 mph gusts around southern and western coasts and hills, persistent rain to go with it. little bit drier in eastern areas of england first thing. the rain is spreading north and east quite smartly through the morning. maybe just clipping the east of northern ireland and into southern scotland first light but much of northern ireland, a good part of scotland, a dry and bright start with some sunshine, although in the hebrides, some of the strongest of winds. 50—60mph gusts in the morning with outbreaks of rain. but getting better here, compared to the rest of scotland where it will turn cloudier and wetter through the day, especially through central and eastern parts. northern ireland, just one or two showers clipping the east, many will have a much better day than saturday. england and wales, the cloud and persistent rain of the morning will ease back to sunshine and showers for the afternoon. some of those on the heavy side, but also, note the temperatures. it will be the first day in a while where we have seen temperatures lower than the average for this time of year quite widely. into sunday night, lots of dry weather, clear skies but a few showers to southern and western areas later. still have a south—westerly wind.

while we dropped down into single figures in rural parts of scotland, northern ireland and northern england, further south, temperatures will be in the mid—teens. we start the new working week not on a cold note but with low pressure still circulating to the north—west. still pushing weather fronts our way. these are not as potent as sunday's. a fairly fragmented area of cloud and rain spilling northwards and eastwards. still breezy but not as windy as on sunday and a bit more sunshine between the afternoon showers. the showers heaviest and most frequent the further north you are. temperatures still in the teens here but getting back into the mid—20s for some towards the south and the east as they will be again on tuesday. always a bit cooler and breezier further north you are on tuesday with a few showers still in the forecast.

but after a fresher and showery weekend and start to next week, things do warm up later on. summer is not done yet. hello and welcome to bbc world news. i'm nkem ifejika. our top stories — at least five are dead as a huge wildfire sweeps across northern california. 0fficials warn residents must evacuate if they're asked. the worst thing that happens is people refuse to leave, and then the fire is coming and then firefighters are placing themselves in harm's way. tens of thousands join rallies across russia to protest against plans to raise the pension age. more are planned for later. final campaign rallies in zimbabwe ahead of the first election since robert mugabe was ousted as president. pope francis accepts the resignation of a prominent us cardinal following allegations of historic sexual abuse.
