and an increase in fraud. a bbc investigation reveals almost 50,000 older people were victims of scams in the last year. now on bbc news, it's time for 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, 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 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 his 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 it takes you 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 are digitally preserving this you are 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 are looking at visualisations of new architecture, new buildings, where you have people who are exploring things. so seeing a physical form 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 is the excitement. 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 provide 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 global success stories. these include sundar pichai, the ceo of google, and more recently, binny ba nsal. 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. while 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? 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, work in data companies. we didn't have indian product 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 growth in the number of start—ups and people working in... why is that? multiple reasons. we have a lot bigger market, lot bigger economy, 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 execute. what do you think india is really good at? i think one thing 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 will have the next google or microsoft coming out of india, because indian entrepreneurs and their leaders can scale businesses globally much better than maybe their chinese counterparts. what do you think india is not good at? given our evolution, and the success here that we have had, we tend to take shortcuts to problems, because so many other things are broken, so that is something that needs a mindset change.

artificial intelligence, good or bad for india? i think both. it is very hard to predict which side the penny falls. great because it can solve healthcare at scale, it can solve education at scale, it can solve so many societal issues at scale. i can imagine that happening. bad because it is going to take away a large number ofjobs, so that becomes — but i think that is a problem we will define and can be solved with the right intentions and the right solutions. so i am more optimistic than pessimistic about al. thank you 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 deal with the chaotic traffic and environment conditions in india. it is 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 its station in germany. sony revealed either a very small playstation or a very big hand. and a soft—limbed robotjellyfish bobbled onto the scene. 0n 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 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 3d version of the scene that can be rotated and explored. the hope is that the technique could help dancers and athletes learn more about how they move. and what weekly news round—up would be complete without a record—breaking two—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 of 0.6 mph, you can 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 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. this is one of the bbc‘s studios here — that's ashwaria, who's currently rehearsing for click tamil. brilliant, isn't it? in fact, click tamil launches in the next two weeks. and it is notjust 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 will 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 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 is just a taster of that story. these are pictures from jaipur‘thalana national park. they have been filmed using a drone flying at a height of about 30 metres. the drone is equipped with a 10x zoom camera, part of the 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 into action for further monitoring. if there is 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 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 less than that of a mobile phone and this

is 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 with research and 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. 0ne company hoping to ride the ai boom is imerit. and its founder, radha basu, explained how ai won'tjust replace humans, it needs a human 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 ia. 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 ai. we have some examples of the kinds of things that your workers do that we will put up on the screen. these are some examples of what 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 damage, 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 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 is a wad of paper on the street, do you know if it is a rock or a wad of paper? so when we do this pixel segmentation it is 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. so that, i think, is the core, i would say the core

contribution of imerit. imerit has about 1,500 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 is one thing that you really notice. trees. in this part of the city itjust feels that bit cooler and that bit more pleasant because of 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 is 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 effectively sends you an alarm if a tree's being tampered with. yes, exactly. even if the tree is being cut or 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 tag. there is a small pin which comes out if the tag is 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 are very valuable commodities. the black market price — five lakh rupees, that's £5,500, $7,000. there's, in certain areas of the himalayas there is an active mafia. they have guns and they are violent people. for them we need drone surveillance. we are taking an ideal 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 and 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 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's cut the tree. if you cut a tree you can't escape any more. 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! hello, the last week or so has brought no shortage of wet and windy weather across the uk. the satellite

shows this stripe of cloud, piling in this way. strong winds, but we now have a break in the cloud. it's allowing high pressure a chance to ta ke allowing high pressure a chance to take control. things are much quieter heading into the start of the new working week. a lot of dry weather around. the nights will be quite cold, you'll notice that. there is the potential for quite cold, you'll notice that. there is the potentialfor some quite cold, you'll notice that. there is the potential for some wind and rain at times. it is southern parts that have the wettest weather today, a real soa ker of parts that have the wettest weather today, a real soaker of a sunday morning. the rain clearing away, and as we go through tonight, we are looking at largely dry weather, one oi’ looking at largely dry weather, one or two she was, most have clear, starry skies. from north to south, turning chilly. widespread pale green shades on the temperature chart show that towns and cities are three, four or 5 degrees. 0ut chart show that towns and cities are three, four or 5 degrees. out in the countryside sunspots get to freezing

oi’ countryside sunspots get to freezing ora countryside sunspots get to freezing or a touch below. we could start off tomorrow with a touch of frost. the odd fog patch as well. it turns into a decent state, long spells of sunshine, the odd shareware. not as many as we've had during today. temperatures may be a notch higher. the high—pressure lives still with us the high—pressure lives still with us monday into tuesday. it gifts further eastwards along in frontal systems to squash in. a spit in our fortu nes systems to squash in. a spit in our fortunes developing during tuesday. chilly for most of us, for england, wales, and eastern scotland, some sunny spells. it will cloud over, outbreaks of rain, and increasingly strong winds as well. temperatures, because the wind comes on the south—west, just beginning to creep upwards to 11! or maybe 18 degrees. upwards to 1a or maybe 18 degrees. contrast that with tuesday night, seven areas have the coldest of the

weather, close to freezing. further north, milder, some outbreaks of cloud and rain here and at times. more of a breeze. further south, the middle of the week turns warmer. this is bbc news. the headlines. labour's leadership team say they ‘would back members' on another brexit vote. i'm there elected as the leader of this party. elected as the leader in order to bring greater democracy to this party. there will be a clear vote in conference, i don't know what's going to come out of all the meetings that are going on. and i'm in liverpool where there is a very lively debate and certainly no agreement about whether labour should back another referendum. following eu leaders' rejection of theresa may's chequers plan last week, the brexit secretary says he won't let the eu dictate negotiations.

this is a bump in the road. dictate negotiations. we will hold our nerve. dictate negotiations. we will keep our cool and will keep negotiating in good faith. i think we need to keep these negotiations going.
