donald trump is standing by his supreme court nominee brett kavanaugh as a third person makes claims of sexual misconduct against thejudge. the president said the allegations were part of a ‘big fat con job' by the democrats but did hint he could withdraw support for mr kavanaugh if testimony due to be heard later is convincing. the real name of one of the men accused of the nerve agent poisoning in the english city of salisbury in march has been revealed. an investigative website says the man who called himself ruslan boshirov and said he was a tourist is in fact a colonel in russian military intelligence. and the anti—kremlin activist pyotr verzilov who is believed to have been poisoned has been released from hospital. the pussy riot band member who fell ill in germany two weeks ago says he "firmly believes" he was the target of russian secret services. it's just gone half past three in the morning. now on bbc news, click. this week:

a stage in delhi, a screaming crowd, and a man with my face on his shirt. india — a technology superpower in waiting. half of the 1.2 billion people here are aged 35 or under. in the years that we have been coming here, we have seen it change from an it outsourcing work house to a place of innovation and start—ups. and although click has a huge audience in india, and although we have brought indian stories to the world, we haven't yet been able to bring the world to india. so, it is high time we put that right. we have taken the click live show on the road, actually on a plane, to the beautiful setting of bikaner house, new delhi. new delhi! thank you for having us! are you well? cheering and applause. and it is here that we wowed audiences with the coolest tech that we have seen on our travels. we painted colours in the air, tickled their ears,

took them to the future, and to the distant past. this is hampi, once the capital of the vijayanagara dynasty, and by the 16th century it was the second—largest mediaeval era city in the world. since 1565, it has lain in ruins, but over recent years, this unesco world heritage site has been 3d—scanned by several different organisations. not only does this mean that what is still there can be digitally preserved, but it has also meant that historians have been able to reconstruct a virtual model of how it would have looked in its heyday. so, we are now going to take a walk—through of the temple site. to do that, we also need a projector, which will shine down onto the model, and a camera up there which is going to watch for the routes that i want to describe. and this is how i'm going to show it where i want to go. once you have described your route, you're taken on a virtual tour, and while you enjoy the scenery

on the screen, you can see exactly where you are on the model too. if you digitally preserving this, you are really keeping it forfuture generations, to be able to really see what used to be existing. the laser pointer and footprints are just the first experiment into how others might experience this kind of virtual tour. it's crying out for a virtual reality set—up, obviously. and this technique would also be useful to explore sites other than those from times gone by. this kind of whole technique i think would go very well when you're looking at visualisations of newer architecture, newer buildings, where you also have people who are exploring things. so, seeing a physicalform and a virtual form together, it will really help people to be able to visualise things and also maybe change, digitally, you can change anything, so that's the excitement, i think. visara technologies is one of many start—ups that are being spun out of the 23 indian institutes of technology,

universities which span the country, providing a tech education for tens of thousands of young indians, and incubators to allow their research to be turned into small businesses after graduation. one of the visions of iit was to create world—class engineers and world class projects, and perform world—class research, and it has certainly had some big global success stories. these include sundar pichai, the ceo of google, and more recently, binny bansal. he's the co—founder of flipkart, a massive online shopping site launched in 2007, six years before amazon arrived in the country. it's considered one of india's most successful start—ups. and when walmart recently bought most of the company, the deal made binny a billionaire. and whilst in delhi,

i could not resist grabbing a few minutes with the man himself to get a snapshot of the indian tech industry. how have you seen the indian tech scene change in the last 20 years? i think the indian tech scene really started evolving in the last 10, 12 years. 20 years back, there was not really a tech scene, the tech scene was people who would graduate and go to the us, and work in data companies. we didn't really have indian data companies, there were a handful, literally, you could count them on yourfingers. so, it really started changing in 2011-‘12 when a lot of start—ups started coming out of india. i think in the last ten years, there has been just an exponential rate of growth in the number of start—ups and people working in... why is that, do you think? multiple reasons. i think one is that we have a lot bigger market, lot bigger economy, most importantly, we have a lot more people on the internet. ten years back, we had 15—20 million people on the internet,

now we have more than 350—400 million people connected. that has created a huge market for indian entrepreneurs now to really dream big and then execute. which wasn't the case before. what do you think india is really good at? i think one thing i believe india is really good at is producing global leaders, if you look at companies like pepsi, google, microsoft, a lot of the ceos today are indian. and that kind of gives me hope that one day not so much in the future we'll have the next google or microsoft coming out of india, because indian entrepreneurs and their leaders i think can scale businesses globally much better than maybe their chinese counterparts. what do you think india is not good at? given our evolution, given the success here that we have had, we tend to take shortcuts to problems,

because so many other things are broken, so i think that is something that needs a mindset change. artificial intelligence — good or bad for india? i think both. i think it's very hard to predict which side the penny falls. so, great because it can solve healthcare at scale, it can solve education at scale, it can solve so many of these societal issues at scale. i can imagine that happening. bad because it is going to take away a large number of jobs, so that becomes — but i think that's a problem we will define and can be solved with the right intentions and the right solutions. so, iam, again, more optimistic than pessimistic about al. thanks for your time. thank you. back at the live show, when we weren't creating the world's

greatest selfie, or playing the world's best game — designed by click, patent pending, incidentally — we spoke to the pioneers of india's burgeoning space industry, and asked the question on the minds of overi billion people — can a self—driving car survive india's traffic? over the past few years, we have been developing the technology, as you can see, the vehicle can see without radars, then we have developed software to actually deal with the chaotic traffic and environment conditions in india. it's a very hard problem and so far we have done some tests, but it would take us a lot more time to go into the indian cities and deal with the chaotic traffic and peak traffic hours in india. see? not quite as crazy as you first thought. hello and welcome to the week in tech. this was the week when the world's first hydrogen powered train rolled into a station in germany. sony revealed either a very small playstation or a very big hand.

and a soft—limbed robotjellyfish bobbed onto the scene. on dry land, elon musk has been getting into trouble over his tweets. on monday, he was sued by the british cave diver that he had accused without evidence of being a child abuser. then the us department ofjustice opened an investigation into financial tweets made by musk last month. but in a bit of good news, spacex just found its first passenger for its mission to the moon. a junk—hunting satellite has captured space debris for the first time. the prototype device successfully snared a metal object in a net from a distance of six metres. the weight of the net will eventually drag the debris into the atmosphere where it will then burn up. mit's csail lab has revealed research to create 3—dimensional motion sculptures from normal 2—dimensional videos. by picking out the structure of the human body, the system can recreate a 3—d version of the scene that can be rotated and explored. the hope is that the technique could help people like dancers and athletes learn more about how they move. and finally, what weekly news

round—up would be complete without a record—breaking 2—ton spider robot. dubbed mantis, this 5m—long hexapod is the work of british engineer matt denton. he's built dozens of small robots, but this is the first to win the very specific accolade of largest rideable hexapod robot. but with a top speed ofjust 0.6mph, you can certainly outrun it in person, if not in your nightmares. now, i'm not sure if you know, but as well as being broadcast around the world in english, click is also remade specifically for 110 million farsi speakers mainly in iran, afghanistan, tajikistan, and uzbekistan. and now, we are expanding further. one of the main reasons we were live in new delhi was to celebrate the upcoming launch of clicks in several different languages, and to introduce the people who will be hosting them.

are you ready? the base of the bbc‘s indian operations is here in delhi, it is the largest bbc hub outside of the uk. it is here that all the languages come together to generate their own stories and share content between each other. you have tamil, murati, hindi, gujarati, punjabi and telegu. welcome back to click! this is one of the bbc‘s studios here — that's ashwaria, who's currently rehearsing for click tamil. brilliant, isn't it? and, in fact, click tamil launches in the next two weeks. and it's not just about india either. eventually, click will be broadcast in more than 20 languages. the great thing about all of this is notjust that we will be able to reach huge audiences in their own languages, but we'll be able to bring you stories that these guys are discovering on the ground. stories like the app that helps to donate food to the poor, an artificial intelligence that helps in employment and recruitment,

or even a smart chessboard. very hogwarts. and then there are the drones being used to prevent poaching in india's national parks. here's just a taster of that story. these are pictures from jaipur‘thalana national park. they have been filmed using a drone which is flying at a height of about 30 metres. the drone is equipped with a 10x zoom camera, these are a part of the surveillance system being tested here. in the park spread across 32 square kilometres, many towers have been installed. each is fitted with a high—resolution camera that can rotate at 360 degrees. and these can be monitored from a control room, which is situated several kilometres away from the park. in case any movement is captured on these static cameras, the drones can immediately swing in action for further monitoring. if there's any danger to any animal

or any illegal activities observed, the drones can monitor the situation till forest officials reach the spot. recordings of cameras can be seen on a portable device. with the help of real—time tracking, it is easy to reach to the location. at present, drones have been operated manually, but in future, they can operate on their own with the help of artificial intelligence. translation: as soon as the target is detected at the mission control centre, a drone will automatically take off and reach the localised position. so it is possible that in future these drones not only talk to each other, but will also be able to take decisions related to surveillance on their own. the company that

manufactures these drones claims that the radiation used in the system is even less than that of a mobile phone and this is completely safe for animals. but one cannot rule out the possibilities of bird hit. the state government of rajasthan plans to implement this technology in other national parks as well. they believe this will help in not only strengthening the safety and security of wildlife, but will also help promote research and help in better planning. one of the big themes that came out of click live in india was the power of artificial intelligence and its impact on people's work, especially on theirjobs. one company hoping to ride the ai boom is imerit. and its founder, radha basu, explained how i won'tjust replace humans, it needs a humid workforce

to train the algorithms in the first place by clearly annotating training images like these. could you explain to everyone here what imerit does? in order for al algorithms to work, they have to be trained. it's like computer programming. if you just put a computer there and say work it doesn't work. so you have to programme it. that's called training ai. what we do is train ai and enrich the data so that our clients can get the best results out of their ai algorithms. so you have a huge human workforce training ia. -- ai. we have some examples of the kinds of things that your workers do that we will put up on the screen. that we will put up on the screen here. these are some examples of that your humans are doing to create this training data, yeah. that's correct. we are called humans in the loop.

humans in the loop of ai. so it could be as simple as taking different cars in a parking lot, doing bonding boxes around them, knowing which cars have damaged, so being able to look at automatically picking that up and sending back that like an insurance investigator would do. this is where we have probably done the most work. we have done more than 15 million images for self driving autonomous cars. we work with a variety of car manufacturers. and if you look at this, it's called bounding boxes and polygons. but it's at a pixel level. so it's dense pixel segmentation. so think, for example, there are a few toes onto the crosswalk. how do you know whether that belongs to a cat, to a small child? there's a wad of paper on the street, do you know if it's a rock or a wad of paper? so when we do this pixel segmentation, it's very complex and you can have up to 50—70

different things you are marking. just to be clear then, you're training the ai, this is a person, this is a car, and then it goes away and learns from that? so when a car looks at the street scene, we have trained the ai algorithms so that the computer can learn from it. for the first time, we have technologies in al that can be used for crucial societal applications, particularly like healthcare. there are, in the amount of data, healthcare is about a third of the data. and the ability that we have, as you can see there, this is our work, where you actually can go in and look at cancer cells and we actually annotate them in these images and use this to train the ai algorithms. and if you think about this in a broad societal sense, this can be taken to a large number of people who do not have access to this kind of care and you can do pre—screening for cancer cells. what is really important is the type of person that you employee.

—— employ. so that, i think, is the core, i would say the core contribution of imerit. imerit has about 1500 people, we are hiring 200—300 people per quarter. so ai is creating jobs. wow. 50% of the workforce, for a technology services company, 50% of the workforce are women. yes. applause and 80% of the workforce are coming from low income backgrounds. they could be young muslim women. we have a centre called the centre of excellence for computer vision. that's for image processing. and that centre is all young muslim women in a very poor community. so you can imagine that this is creating jobs that right

from the beginning is inclusive of the workforce. it has diversity. and it has a lot of moral ethics that go with it. the streets of new delhi were designed at the beginning of the 20th century as india's capital moved here. and, compared to much of the development that has followed since, there's one thing that you really notice. trees. in this part of the city, itjust feels that bit cooler and that bit more pleasant thanks to the shade provided by these tree—lined avenues, that were planted way back then. in fact, in delhi, fierce battles rage whenever the thought of chopping down trees is even suggested. air quality here, as you probably know, is terrible. and trees are seen as at least part of the solution. and now, get this, plans are afoot to build a green wall around the city.

a ring of more than 3 million trees to protect against dust storms and other pollution. and it's notjust here in delhi that trees are big news. david reid headed for the troubled forests of shimla, which has seen huge amounts of illegal logging. the question is, could technology help? if you like trees, you will love shimla. pines sprout from the tarmac, houses are built around them. the forest department numbers every tree, so they know if any go missing. many do. one reason is because constructable land here is so scarce and costly. property fetches a premium on the market, a massive amount of pressure on trees to cut them down and turn that land into land

that can be built on. now the forest department is turning to technology to fight the felling. like radio frequency identification, the tags shops use to stop people stealing stuff. the earlier method was to number these trees physically on the ground. but now we can put these rfid tags so that it can be monitored remotely. 2a hours a day. you set up a radio network that are effectively sends you an alarm if a tree's being tampered with? yes, exactly. even if a tree is being cut or if an axe is being used on this tree, the vibration gets into this. so what's to stop me from just pulling off the tag and cutting the tree down? how is it going to work? there is a pin inside?

yes. if you look at the reverse of this rfid tack. there is a small pin which comes out. if the tag is being pulled out, from the tree, then a signal which directly goes to the receiver. we took to the woods to see a spot where trees may have been illegally felled. a local lawyer who led us there believes tree protection has to be through technology and taken out of the hands of people. they can be influenced, they can be bought, they can be threatened. so we wanted a system which is not based on trust. it is a trustless system based on objective factual reality, which can only come from technology. while he believes this property has been cleared to enhance its value, elsewhere, organised crime is involved. you see these trees behind me, they‘ re himalayan cedars, they're very valuable commodities. black market price — five lakh rupees, that's £5,500, $7,000. there's, in certain areas of the himalayas,

where there is an active mafia. they have guns and they are violent people. for them, we need drone surveillance. we are taking an added view of the images and from that we are stitching them together and running it through our artificial intelligence engine. so this becomes this, allowing investigators to id and locate individual trees. if this area is missing some trees, we can also get the lat and long of that place, so we can go there and check whether it really happened. rfid and drones, a long way from numbers daubed on bark. for the forest department, it's about sharpening their performance and stopping the crims sharpening their axes. the idea currently is that if you cut a tree, there is chance that you might escape. by using this technology, you would make sure that there is no escape possible — for the department,

for the government, and also for the person who has cut the tree. if you cut a tree, you can't escape, anybody. and from david in shimla, back to an excited audience here in new delhi, who from what i could tell up on stage, had a pretty good evening. and that is it for now from india. thank you so much for watching. don't forget we live on facebook and twitter at bbc click, where you can see loads of extra backstage photos and fun. but for now and from this wonderful audience, it's goodbye and we will see you soon. good morning.

it's been a lovely spell of autumn warmth for some of you so far this week. yesterday, we saw temperatures reach 2a degrees in lincolnshire. same spots, though, by the time we hit friday could be a good 10 degrees lower, if not a little bit more. and it's during the next 2a hours we'll see those changes take place. it's all because we've got cold air at the moment pooling to the north of this weather front, which is set to work its way southwards. to start the day, it's across parts of north and west scotland, and because of the more cloudier outbreaks of rain, notice the warmer colours on the temperature chart to start the day. coolest colours in the south, where we've got temperatures in single figures for the morning commute, even a touch of frost in one or two spots. but lots of sunshine through england and wales to start with. bit more cloud north—west england perhaps compared with yesterday. sunshine to the south and east of scotland, northern ireland, but in the north and west, cloud, outbreaks of rain, most persistent in the highlands and islands in the morning, before it turns to sunshine and showers, as that showery band of rain pushes across the rest of scotland through the day, northern ireland into the afternoon and the far north of england.

and so by the end of the day, notice how we reverse the fortunes. cooler air‘s to the north, warmer air‘s to the south, where we could be a degree or so higher as far as temperatures are concerned than we were during yesterday afternoon. the sunshine continues. finish with sunshine across the north, but temperatures in the teens. those clearer skies will work their way southwards behind a fragmenting area of cloud and just one or two showers as it works towards southern counties of england. not quite clear on the south coast for the start of friday, so it'll be a milder night here to take us into friday morning rush—hour. a colder one further north with a touch of frost possible just about anywhere. into friday, high pressure is building in, keeping things dry. but as that cold front clears away, we've got all of us seeing the door open to the colder conditions. so a much chillier day on friday right from the start. we'll see the morning cloud in southern counties of england clear. that will lead to some sunnier conditions for the rest of the day. sunny spells really for most, just a few showers in the north and west of scotland, northern ireland later. but friday, note the temperatures, 12—16 degrees — a big drop on what some have been used to so far this week. and we continue with the cool conditions through the night and into the start of the weekend.

high pressure, though, largely in charge. so a dry start, even if it's a little bit of a frosty one for some of you. sunshine best across england and wales, but clouding over to scotland, northern ireland through the day. showers and outbreaks of rain mainly limited to the highlands and islands, and temperatures still generally around the mid—teens for the most part. by sunday, though, we'll see a bit more cloud drift southwards across england and wales. greater chance ofjust one or two showers here and there. showery scene, though, both scotland and northern ireland. bit more of a breeze, and we stay with things on the cool side. a big change from what we've had so far this week. welcome to bbc news, broadcasting to viewers in north america and around the globe. my name is mike embley. our top stories: president trump attacks brett kavanaugh‘s accusers but says thursday's testimony on sexual misconduct could change his mind on that crucial supreme court nomination. they're giving the women a major chance to speak. now, it's possible i'll hear that and i'll say, "hey, i'm changing my mind."

that is possible. an investigative website reveals that one of the suspects in the salisbury nerve agent attack is a high—ranking russian spy. as many more lose their lives, others give up and head home. a special report from libya on the desperate migrants who fail to cross the sea to europe. and playstation gives in to gamers, allowing fortnite fans to compete with players on rival consoles for the first time.
