ina the indian prime minister, narendra modi, has arrived union right it they will they are —— the indian prime minister, narendra modi, has arrived in the southern state of kerala to see the devastation caused by the worst floods there in a century. weeks of rain have triggered landslides and floods killing more than 300 people. a state funeral for some of the victims of the genoa bridge collapse will take place in the city later on saturday. 38 people are known to have been killed with the search for another five continuing. the government has begun action against the motorway management company. the former cricket international, imran khan, will be sworn in as prime minister of pakistan in a few hours‘ time. he won last month's election on a pledge to fight corruption and to lift millions out of poverty. his opponents are continuing to claim that the voting was rigged. now on bbc news it's time for click.

this week, it's a look back at the summer. we will start with a trip to f1 from july, which has been at the cutting edge of technology and design since its creation in 1946. welcome to the pet. every year, teams compete to outdo each other in aerodynamics,

data communications, and materials, all with one aim: to make their cars go really, really fast. can they do a really good job? we are finding out at the austrian grand prix. lewis hamilton's ride. what is 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. these are the most expensive motorhomes i have ever seen. it is one of these isa have ever seen. it is one of these is a lorry, and a drive into the next formula i, stick them together, and that is ferrari's offers for the length of the race. mercedes are the current world champions, and like every other team here, they spend millions on their cars are developing a technology that will hopefully win them the race. but what you see at any grand prix is

just the tip of the iceberg. it ta kes just the tip of the iceberg. it takes hundreds of people to develop the technology. so we sent la out to mercedes hq to find out which goes into winning a race. —— lara. —— what goes into. hello. can i put security stickers on your phone? of course, no problem. so we are allowed to take video here but not ta ke allowed to take video here but not take pictures on my phone. there is a lot at stake, so it is no surprise that formula i is notoriously secretive. but today we have some behind—the—scenes access. this business is big bucks and millimetres and milliseconds matter. this is largely's winning car. in

fa ct, this is largely's winning car. in fact, it has not even been clean, clea n fact, it has not even been clean, clean since its last race in abu dhabi. but the most striking thing standing next to it is the amount of detail that there is a director at the car. after each race, if there is something they are unhappy with, it can be perfected. this was a winning car last year, so clearly it has been very successful. and you are has been very successful. and you a re clearly not has been very successful. and you are clearly not happy with it, because you're working on a new one. so what you think needs to be improved? never happy with it. this is lewis hamilton's car carfrom last year. we worked really hard on all of those little small bits you see around the car, which is all the aerodynamic bits and pieces. see around the car, which is all the aerodynamic bits and piecesm see around the car, which is all the aerodynamic bits and pieces. it is made up of lots of little pieces. every piece has a drop. every piece goes into the wind tunnel and we try to optimise airflow around the car. when we are not happy with a little bit, if we focus much on that, we need to do a lot on the packaging, internally, to make sure it is tight. the parties and get it, the

better dynamics around the car. 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 look at the data and make sure that vital advice can be provided. 0n the screens, they will be looking at a feed for the race. they will be looking at feeds from the driver's cars, and all the data that they want to act on. if they wa nt to that they want to act on. if they want to communicate, that they simply do to a therapies. that times, gps data, everything can be tracked and analysed amir, with 5000 different data points being assessed. information from races in europe take just one of a second to reach here, or a of the data is coming from australia. meanwhile, this lot are busy practising at

speed. 0ver this lot are busy practising at speed. over 250 of these trials take place at the season, making it look easy. inevitably it is not. i can show you how. 0h, easy. inevitably it is not. i can show you how. oh, no and! so loud, and it is meant to be so quick, but i wasn't. meanwhile, and it is meant to be so quick, but iwasn't. meanwhile, spencer and it is meant to be so quick, but i wasn't. meanwhile, spencer is ready living life in the fast lane. thank you. either way, this is that you really do it. this year, mercedes has its pitstop down to an incredible 1.85 seconds. that is quicker than it takes to say 1.85 seconds. it was a finely tuned

operation that the engineers practice over and over in the days before each race. it is a bit of a ballet. the ergonomics is quite important, because they are 20 people around the car trying to do a job in two seconds. you start banging into google and you lose half a second, second, and in the strategists cannot get their numbers right, and you do not get the position you need. the human element in this ultrafast manoeuvre is covered by technology individually developed by each team. even the hydraulically powered workarounds area hydraulically powered workarounds are a closely guarded secret. hydraulically powered workarounds are a closely guarded secretlj hydraulically powered workarounds are a closely guarded secret. i hear they're expensive? are a closely guarded secret. i hear they‘ re expensive? they are a closely guarded secret. i hear they're expensive? they are expensive and they need to withstand a lot of pressure. £30,000 each? i would not know the exact cost of them, but they are a lot. we are going into mercedes garage, now. giving the pit crew safe is of utmost importance. these lies, for

example, let the crew know if the ca i’s example, let the crew know if the ca rs have example, let the crew know if the cars have become electrified, stopping them from getting a nasty shock. —— lights. then there is what goes into the cars are what comes out of them, which is monitored by trackside labs and high—end equipment. between every session, the cars are given the equivalent of a late test. the oil and the fuel is taken to detective who is contaminated, and that will give you a clearer idea of the engine. that is done and if you allowed. the oil is done and if you allowed. the oil is put into a spectrometer, which tests for different metals in the fluid, the amount of a specific metal present showing if a part of the engine is degrading to quickly. and next in our summer of sport special, we are going from the formula 1 to the world cup. that is ina formula 1 to the world cup. that is in a couple of text. —— ticks. hello and welcome to the week intact. this

is the week that facebook signed an exclusive deal to show gains from india and pakistan. and ten current and former tinder staff are suing the committee for $2 billion, accusing them of undervaluing the dating app and chicken out of companies stop. the committee has called the claims meritless. and by last week conspiracy theories alex lowes may have avoided a good banter may he has been banned for a week from posting. the host of info wars will not be able to interact with anyone during the period that is produced which will be visible. it was also the first time a birth control app was authorised by the authorities in america. and a study

by moorfields eye hospital and would's deepmind showed that al can diagnose eye disease as accurately as experts. it is hoped that it will be able to flag and refer urgent cases and is the burden on specialist. and finally i leave you with the disembodied head of thomas the tank engine's by with a head programme to seeing karaoke. —— sing. next up in our celebrations sports, jen gets is on ——jen gets her boots on. he might not look like much, but this robotic goalkeeper can stop me's best players. his two cameras take up to 90 voters per

second. if a football is kicked to robokeeper has just played through the second to save the ball. —— 0.3 ofa the second to save the ball. —— 0.3 of a second. the great facilities in manchester, as you would expect in one of the world's great footballing cities. normally, there is a huge amount of set up, but what if you could bring it to your living room? we are trying out the latest in virtual reality, those collecting data with statsports. using a hardware monitor and a device that to my shoulder blades, we are set for a to my shoulder blades, we are set fora run to to my shoulder blades, we are set for a run to collect information. virtual reality has this data transformed amazingly quickly. we

have upset that data back on the pitch. —— offset. as we move forward , pitch. —— offset. as we move forward, we can stream this light into the platform, so theoretically, if you go in at half—time, or during the world cup, there is a review, like tactics, reviews, positions, this is the future. there are also russia drills that have been created in the to reality. —— pressure. this sta niforth in the to reality. —— pressure. this staniforth has been shortlisted for the women's fa goal of the year. smashed it. the game realism, it is spot on. the defenders close on me was — kell brook pressure. evenjust fine—tuning level skills, summary cultures outside the box, i not happy with that, so that competitive

edgein happy with that, so that competitive edge in work and that, it is all good. ——i edge in work and that, it is all good. —— i felt edge in work and that, it is all good. —— ifelt the pressure. another incredible development is being put yourself in any position on game. obviously, it raheem sterling, given he is a fast player anywhere, he has the advantage. as the defender comes in, they would have deterred many hits, and that weight, i suppose. lucy is watching a real match that took place between manchester city and monaco. chicken places offered any position on the pitch. in the stands, on the roof, and even become the manager. right now, i had a clear view of what went wrong, in terms of the left back‘s position. so do you see more in the player's positions? i think so. there is so much value in actually appreciating the picture that they salt. so for the first time, this is all portable. you can bring the match analysis loaded on an st card

01’ match analysis loaded on an st card or usb stick, the headset, and put it in your bag, and the night before, you can review the opponenfs before, you can review the opponent's tactics from anywhere on the pitch. but to play against their virtual keeper, you need to be back on the wired version. yes, one! that are only takes out any chance of injury and is more controllable, and the fatigue level can be lower. i think it is really cutting edge, and we are think it is really cutting edge, and we a re really think it is really cutting edge, and we are really glad to be up to get involved in that space. you did quite well. nice one, jen, and that this chip is that world cup finals in russia, data played a bigger role

than ever. before the tournament, paul carter went to fit to find out how. actually, data is an integral pa rt how. actually, data is an integral part of football. you cannot be what you've put up —— without being bombarded by statistics. analysts committed to our matches in real—time. the snappily titled electronic performance and tracking system will provide data on metrics such as distances run, speed, and position information. crucially, it could be 32 countries competing in the tournament will be provided with two ta blets the tournament will be provided with two tablets will stop one for a data a nalyst two tablets will stop one for a data analyst in the stands, will be to communicate with the second device you not on bench can't possibly an assistant coach or manager. —— unit

on bench. we know when the players and where the ball is at any time any match. we have different metrics available to the analysts, and is with resources available for technology differing between countries, fifa hopes this technology will bridge the data divide, bringing the digital haves closer to the digital have—nots. lots of the team already use data. we expect a lot of teams coming to russia to bring their own set up. but we want to at least offer the same to all of the teams. in fifa's system, the team's data analysts will have access to a tactical app enabling them to add drawings over a live video feed. stills can then be sent to the dugout. with goalline technology, video assistant referees and now bts, this year's world cup looks set to be the most logically advanced ever. but with all this

technology, how big is the risk that we lose the real spirit of the game. the role of the data analyst is simply to support those coaching decisions. i think there are some key insights which can be found in the data, but football will always be those 22 players on the pitch and the coach is always going to be the person who makes the decisions.- the end, what technology is really for is only to support. at the end, that is, you know, i for is only to support. at the end, that is, you know, lam for is only to support. at the end, that is, you know, i am a for is only to support. at the end, that is, you know, lam a big foot ball that is, you know, lam a big football fan and you are a big foot ball football fan and you are a big football fan, it is about the 22 players plus the referee, 90 minutes. a penalty shootout, germany versus england, maybe. that is the excitement. i think technology can only add additional help, optimise processes and optimise ways of providing information. that is what technology is about. that was paul at fifa. data has also massively transformed the sport of cycling.

but the epic proportions of the tour de france make electing data from the ride is a lot more difficult thanit the ride is a lot more difficult than it would be in the velodrome. cat hawkins went to find out how one of the oldest sporting competitions in the world was solving the problem of gigantic geographical —— geography. 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 data is playing more of a role than ever before. cycling is becoming increasingly data driven, and the good reason. masses of data can be collect it, and in a sport of fine margins and superhuman endurance, those insights are the key to energy efficiency, strategy and games. we look at many things. we look at heartrate, we look at data, their maximum power and elevation gain. we look at that and we see how the

riders are building and we look into that data to try to make them better and stronger in stage races. but how was the data collected and transmitted? was the data collected and transmitted ? that was the data collected and transmitted? that is where these little devices come in. it may not look like much, but this small clip on devices on the back of every bike taking part in the tour de france this year. it has actually been revolutionary. the sense or is on the bikes and real—time location data to a nearby vehicle then beams up data to a nearby vehicle then beams up to data to a nearby vehicle then beams uptoa data to a nearby vehicle then beams up to a following helicopter. —— sensors on the bike. it is then sent to the data truck for real—time analytics. this is where the magic happens, from bike to motorbike to helicon to do here. this is where all the data for the tour de france is being stored. the data truckers we re is being stored. the data truckers were data is analysed, enriched and visualise the broadcasters and teams. there is even in a data for machine learning algorithms to get to work. the depth of data analytics produced from simply a gps device is staggering. contextual data such as 3-d staggering. contextual data such as 3—d maps, weather, gradient underwriter information is also

added to bring the data to life. during the race, riders were earpieces, and following close behind them is the data car, whether tea m a na lyst behind them is the data car, whether team analyst is dissecting the data and feeding them live information. as to what happens in here, it is quite an important place, isn't it? imagine if you have a communications office and you try to fire a rocket to the moon, and ijust feel like we are that place at nasa were all the details come in. and they come in from all directions. and then we send out one message to the riders. hundreds of data sets are analysed, from competitor tactics to live course conditions. we analyse all of the climbs, the gradients, the road surface is comedy with the roads. any road furniture, anything coming around a blind corner and there is a pedestrian crossing. all these kinds of things, we try to find. 0n the tour de france, with restrictions on sponsorship deals, we don't get any heartrate or power data, but we do get location, which is absolutely

crucial. because we can make decisions much, much quicker. so we are in the race. this is happening live. what are we saying to the riders? we are saying, come on, serge, you've got 250 metres more hard. around the next corner, hairpin, you can't see it but it flattens for 250 metres. you'll get some respite and will got drinks in 400 metres, cool down, take your drinks and will take you on to the finish. nice. i can drinks and will take you on to the finish. nice. ican automatically see the psychological impact of that is huge. but how do the cyclists themselves feel about data and sport. having everything about you measured in tract can have its downsides. of course, a lot of teams are trying to keep it secret, because, yes, when you are racing to win the tour de france you don't really wa nt win the tour de france you don't really want to give your competitors that advantage. people say it is now just turn into f1, it isjust that advantage. people say it is now just turn into 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 too put

the effort in. biometric data isn't actually transmitted live. but that isn't because of technical limitations. the data ownership between the writer, the teams, the race owners, it is still quite complex, and so at the moment the data we do have permission to collect and publish is positioning data that we can then tell stories about speed, gradient and positioning. it is possible to take biometric data, and we have piloted that at the tour of california a couple of years ago, and in a stadium of eye on it. but for the teams it is sensitive because that biometric data also gives great competitive insight about how hard that rider is working to perform the way they are. as well as sponsoring their own team, dimensional tap back data is the technology company behind all the data collected for the tour de france. that technology has managed to overcome problems unique to this epic race. we have been studying this tracking system for 15, 20 years. the big thing we

have to deal with these, we are in the middle of nowhere, in the middle of the mountains, the weather conditions can be horrific sometimes. so this is the main thing, logistically speaking, to be able to install the tracker and give information in real time. that is the most complicated it. from data centre to road race, there are 20 kilometres to go, 20 kilometre wind speeds. the final is coming up. and from cat in the saddle to me in court. in the run—up to wimbledon, i found myself in boston with a little robot or collector. —— ball collector. the telebot autonomously patrols the court which are logged,

smashed in my case mis—hit. —— tennibot. any ballboys or ball girls out there who are worried about their jobs, out there who are worried about theirjobs, don't worry, this isn't designed to replace you at the tournament. this is more the people who want to practise and are not good and end up with a lot of walls in the net. so you can carry on practising and big tennibot will just go around picking up the balls while you are busy being rubbish. it is on bought —— its on—board camera spots the balls and its partner at the net helps to keep track of things as well. it also has a handy detachable basket so you can easily return your balls, if you have too. then you can retire to your air—conditioned car, ball collecting bucket and wheels in tow, and nobody will ever suspect that you are the laziest tennis player alive. and that sits for this week. —— that is it. next week we have another chance to see our sustainability special from earlier in the year, when we will be talking gravity trains,

hurricanes and coral reefs. in the meantime you can follow us on facebook and twitter. from tennibot and me, see you soon. hello there. this weekend, again, we look to the atlantic to see where our weather is coming from. we're going to add into the mix, just for good measure, the remnants of an old tropical storm. it will feel quite humid out there this weekend. for many it will be dry on saturday, more rain for some on sunday. there was a fair bit of dull, damp, cool and wet weather across some parts of the country on friday. a lot of that has moved through. this area of low pressure, though, contains remnants of tropical storm ernesto, to arrive in the second half of the weekend.

still got some rain on that weather front there, though. that is strung out across central and southern scotland, the north of northern ireland, perhaps the north—west of england too. south of that, though, we're going to find it probably dry, sunshine at times, the best of which is likely to be in the south—east. temperatures likely to hit the mid—20s or so. north of our band of cloud, patchy, light rain and drizzle. northern scotland, after a windy start, should be dry with some sunshine. here comes ernesto, though. don't have to worry about the strength of the winds. it's more the rain. it'll be quite heavy for a while as it moves over the irish sea, into southern scotland, northern ireland and wales. 0vernight, once again those temperatures no lower than 17 degrees, but across some areas, some heavy rains on sunday — central and southern scotland, northern england and wales. as the rain makes its way eastwards into the midlands, it becomes lighter, temperatures into the mid—20s. improvements in the weather in northern ireland. slightly cooler, fresher, but still cool weather in the far north of scotland, with some sunshine. so we see the remnants of tropical storm ernesto bringing a spell of rain during the second half of the weekend.

it moves away into southern parts of scandinavia by monday, and things calm down just a little. a very flat ridge of high pressure, still a lot of cloud coming in from the atlantic, and developing through the day. the odd shower perhaps up towards the west. patchy light rain and drizzle in the north and west of the uk, but 21 degrees likely in belfast, and 25 or 26 in london and the south—east. that's our monday. as we look further ahead, we still have higher pressure across the south. it's not a dominant high, by any means, and a string of fronts arriving in the north—west, but very late on in the day on tuesday. ahead of that, increasing cloud perhaps, but some sunshine for a while, and the odd shower in scotland and for northern ireland and england. a dry day, a bit more sunshine around as well, and those temperatures more widely into the mid—20s across east anglia and the south—east. the number is not changing too much for scotland and northern ireland. the weather fronts that arrive in the north—west push southwards. there won't be much rain on them at all. but a north—westerly breeze by thursday could drop the temperatures just a little. welcome to bbc news, broadcasting to viewers
