for northern fir“ hifi“fi"fli€“"fl h‘eéibf'ui 1???“ hifi“fi"‘fli€“"fl h‘equfjwiiq e‘tq chilly one for northern ireland and rural scotland, but otherwise temperatures staying quite a bit above freezing. monday, more of the same, local artist of the day across eastern counties of england, burning away with some sunshine. —— low cloud to start the day. 17—18 in the south—east, generally the highest temperatures in the west. hello, this is bbc news. the headlines: the home secretary says there must be no place for terrorists to hide, and called on social media providers to end the encryption of messaging services. her comments come after it was revealed khalid masood used the whatsapp messaging service moments before launching his attack in westminster last week. scotland yard has confirmed the attack carried out by masood took just 82 seconds. detectives have revealed his motive may never be known. they believe he acted alone, despite one of the 11 people arrested in connection with the attack remaining in custody. the family of pc keith palmer, who was killed in the attack, have paid tribute to him and thanked those who helped him

after he was stabbed. they said they wanted to "express their gratitude" to the people who were with him in his last moments. more than 30 people have been injured, two seriously, after a suspected gas explosion in merseyside. several buildings collapsed and others were damaged in the incident, and homes nearby have been evacuated. it could be several days before owners can return. now on bbc news, click. this week, click is back in india. we're hitting the road, the rail and the water. there will be dancing... there will be singing... sort of. driving in india is an experience.

the roads are crammed and the horn is omnipresent and the rules are... well, they're there somewhere, i'm sure. and that's why we will not be doing a story about self driving cars in india any time soon. and despite the fact that it seems like everybody here owns a car, that's not true. many people choose to travel by train instead. but if you think that is any less intense... think again. yeah, about those rules... mumbai central station is a massive, heaving hub connecting the city to the north and east of india.

but if you look closely, you will see something else connecting the commuters to the rest of the world. 116 wireless access points provide free wi—fi to anybody with an indian phone number. it is provided by google which says that about 2.5 tb are being downloaded here every day. and here is the interesting part, this is notjust about this station. along india's railway tracks lie 16,000 kilometres of optical fibre and google is piping internet access down those cables to feed wi—fi access to 114 other train stations as well. the man overseeing the project is gulzar azad, who i caught up with while he was waiting for a train. if you had to take one place in the country where you wanted tremendous fibre, and you had to have reliable power,

relatively speaking, power is a challenge across the country, and you had to have the entire country walking through it there is only one place, that is a railway station. can you guarantee that all services on google‘s wi—fi will be treated equally? absolutely. i think the whole motivation for us, if you look at the reason why we did this, was to see if we could provide an open internet, completely open with access to the entire web. the way the web was designed. so, there is a fibre optic network rolling out from train stations like this to the vast rural areas of this enormous country. and david reid hopped on a train to find out what effect that's having elsewhere in india. it is hard not to be romantic

about the railways of india. british colonial rulers laid track for control, shifting resources — mostly out — and prising open markets. now it's about moving people — millions a day. and thanks to optic fibre, data. i took the train tojaipur station to investigate. it has proper broadband, and it is free. people are filling their booths. apart from some controversy at pune station, where commuters were using free wi—fi to download hard—core pornography, the provision of high—speed wi—fi has been almost universally praised. 90,000 people pass through jaipur station every day. i use the wifi for news

and entertainment. mainly for office work. for this student journalist, it means she can keep tabs on breaking stories. early in the morning, the world changes like... so many things change. i have to come and check. indian stations are full of thriving businesses, feeding off or simply feeding the thousands streaming through them every day. free wi—fi has been a boon to local businesses here. ashok runs a tea stall on the platform. he makes more money now that his customers can make online payments to him. i use the wi—fi when my ag signal does not catch. when that does not work, i use wi—fi, especially when a customer pays digitally. i need it to confirm i have received the payment. digital payments are worth

about 30%—50% of my takings. this is music to the ears of people managing the railways of india. a nationalised industry that runs at a loss. they think that high—speed wi—fi could be a good pull for a station like jaipur. they planned to build a huge concourse and attract retail and services business. it mightjust be an earner. as wi—fi expands and it becomes taken for granted then i think people will transfer more and more of their business. jaipur is a domestic and international tourist hub of high repute. people come out here from all parts of the world. and when you have a huge concourse it becomes an area where you can have shops and entertainment spots. for google, more people online is more people to sell to. india's railway is the country's backbone. its public wi—fi is poised to be at least as far reaching.

welcome to the week in tech. it was the week that laptops and other electronic devices larger than cellphones were banned from cabins on us and uk bound flights, leaving from some african and middle eastern countries. a start—up hopes to be able to provide flights from london to paris by electric plane within ten years, and faster than concorde — supersonic travel between london and new york could be back with flight times of just three hours and 15 minutes after start—up boom supersonic raised $33 million in funding. an app—controlled unstaffed convenience store has opened in shanghai. created by a swedish company, the always—open, never—staffed—by—a human shop requires users to use an app to enter, scan

purchases and to pay. a security camera will be watching. nasa has create an origami—inspired robot that can flatten itself to fit into small spaces. the pop—up flat folding explorer robot, or puffer can cope with extremely high temperatures and, finally, if you could do anything in virtual reality, what would it be? well... if your answer was to play a game of catch with an actual ball then you are in luck. disney research have been examining how the ball‘s path can be tracked, predicted and matched up in its virtual view as it approaches the catcher. 0r... you could just play without the vt headset. you may have noticed by now that the roads here are in india are...

well... utter chaos. what is ever more astonishing — consider that so few people own a car here. there are just 32 motor vehicles per 1000 people in india. in the united states, there are 797. but that number is changing and i'll tell you a secret, it is not going down. look at these roads. that is a scary thought. one solution could be to make better use of the cars that are already on the road. enter 0la cabs, india's biggest taxi hailing app, the uber of india as you will. or as they prefer to say... uber is the 0la of india. founded back in 2010, three years before uber launched in india, 0la has taken full advantage of their head start. 0la have historically been number one in india but uber has said

that that is changing. it looks like the battle for the cab cash in india is onlyjust beginning. these are the head offices of 0la in the silicon valley of india, bangalore. this is 0la's employee number one. india is not designed to have a car ownership rate of... not even 10%. what are the specific needs of your customers and drivers? we made an inclusive platform that is notjust about cabs, but auto rickshaws, three—wheelers, tuk—tu ks that you have, about many other things in india. it's about the buses, bikes, electric rickshaws. it's an inclusive platform for mobility where you have transport options at different price points for different use cases. so that brings an a lot of options for users. 0la say that it is better

because it is local and it knows what works in india. they offer things like walk—in centres for drivers and being the first to allow customers to pay by cash. uber is coming into the indian market. how are you different from them? how will you stay ahead? there is a fundamental difference in the way we operate. we believe in what we want and not what we have. in terms of plugging in things have worked well elsewhere. you need to build from the ground up. it is about the connection that you make, notjust about the transaction. part of that connection is offering centres like this. here, drivers can talk face—to—face with the company, for example when they join the service for training or if they have a problem, an issue with their wages, for example. but 0la does not actually employee any of these people. 0la calls everybody here a partner.

in reality, they are self—employed. that means they do not get things like holiday pay and they are responsible for maintaining their car and paying for fuel. the flipside is that drivers can, in theory, set their own schedule and work when they please. it is a controversial system that transport and delivery companies around the world have used to keep costs down. despite this, 0la really, really wants drivers to drive. a lot. so much so that there are carrots if you stay on the road and sticks if you don't. what india really needs to focus on is to enable mobility for a billion people with the infrastructure we have. we need to leapfrog all sorts of road construction, etc, because it will not take us where we need to go. we need to promote shared mobility, new sustainable options, our government is focusing in a big way on all vehicles

being electric by 2020. electric vehicles do not produce the same amount of pollution that we see here. 0la is one of the most successful start—ups to come out of the education sector in recent years. called indian institutes of technology, or iits, these top—level universities are dotted across india and they are the driving force behind many of india's technology successes. getting into iit is an incredibly competitive business. only a tiny fraction of applicants get in in any year. but if you do, you get to work in incredible campuses like this. my first appointment is at the 0lympic—sized swimming pool — although it's not me who's taking a dip. this is matsya, named after the avatar of vishnu —

which takes the form of a fish — it's a multipurpose underwater robot that can operate autonomously, without a human controller, to locate sounds, and recognise, grab and manipulate objects. the team tell me it might be used to find flight recorders from crashed aircraft, although they're also pitching it to the military to fire torpedoes. the project is in its fifth year, and the team leader tells me the work is hard, but can be massively wide—ranging. like a racing car, or a satellite. brilliant! matsya is one of 100 projects that have been supported by iit bombay‘s society for innovation & entrepreneurship since 200a. sine is an umbrella for start—ups

and, as with incubators everywhere, you'll find all kinds of ideas bubbling away behind its doors. as you might expect, there are aerial ideas, there are medical ideas, but there are also musical ideas — which is why you find me making strange noises with my face... doooo—deeee—doooo. .. very good. you got some score over here. "some score"! if you do it better, your score will increase. yeah, the worst karaoke india has ever heard. but then, this singing—training app is so much more than normal karaoke—style games. most karaoke apps do a very cursory kind of evaluation of your singing. some of them don't even value the singing, theyjust some input — you just open your mouth, you get a good rating. what we do is a multidimensional

evaluation of your singing on different aspects of music — pitch, rhythm, falsetto, dynamics, timing... eeeehhhh—oooohhhh... what?! you asked for a hard exercise! eeeehhhh—oooohhhh... eeeeeh—eeeeee—eeeeehhh. .. echoing. if my singing went right through you, i've got something upstairs that will really cut to the bone. the algosurg team are working on a system for surgeons to plan surgery. they've created software that's learned to create a three—d model of bones from just two two—dimensional x—rays. i can imagine, after a lot of experience, a bone — if i just look at an x—ray, i can imagine it in three—d. can we do the same thing with computers?

a surgeon can do it, because he has learned a lot of correlation between x—ray image and that 3—d bone which he sees during the surgery. we used the same logic to develop the software. we have a machine—learned algorithm which has learned the three—d shape of bones across the population. we have created a lot of 3—d models from ct scans, and we used this as a kind of database, and we create an algorithm to understand that database in a very particular way to predict a 3—d model from an x—ray image. these 3—d models also allow for tools and guides to be designed to the patient‘s specific dimensions. for example, if a surgeon was preparing to cut and realign legs. we have a special, specific instrumentation which uses the bone surface in 3—d, and it is like a negative of the 3—d bone surface. if you make that part and print it in 3—d, and put it on the real bone, it will exactly fit

in a very unique fashion. so what we do is, we use that concept to cut, to make surgeon cut more accurately, so this part will be exact fit on the bone, but it will also have a slit which will be aligned with the cutting plate. that slit can be used during the surgery to guide a cutting tool. two x—rays are, of course, cheaper than a full 3—d ct or mri scan and, once again, it means patients can be assessed who can't get to a fully kitted hospital. it's no surprise that many of the projects here concentrate on low—cost, rugged solutions to developing—world problems. you may have come across braille displays before, which allow you to connect via bluetooth to your android tablet, then whichever menu item is highlighted on the screen, the text is mirrored on the braille readout here, and you can control the navigation using up and down buttons here. well, this is a prototype braille display called brailleme, which works in a slightly different way. the braille displays currently

existing on the market are based on piezo—electric technology. because of that very thing, the cost of these devices are around $2,000 to $3,000 each. we developed a completely new technology based on magnetics through which we are able to reduce the cost 10 times. we can sell it to the user at a price point around $300 to $1100. this machine needs to work for at least 10 million cycles of up—and—down movement, it has to be quiet, low power — all of those features make it very difficult to make such a compact device. so that is the challenge. this is the anjuman urdu primary school in the town of kundapur in karnataka. my my name's spencer... there are 155 kids here from grades 1 through to 7, and a whole bunch of dedicated teachers.

and this is how they start their day. singing. over in vuaya nayak‘s classroom, things are a little more serious. so, at the back of the projector, there's an android device which is plugged in and is running videos on english, maths and science. the videos are made for the entire region. but then they're dubbed in different dialects, different languages, depending on where they're being sent to. today, we're learning about fractions. it is great teaching tool — as long as there is electricity. but there are plenty of times when there isn't. translation: this is a billet school. 0rdinarily, it would be difficult to teach because of power cuts.

we would get electricity in the mornings but, as the day passed by in the afternoon, we would have power cuts for more than two hours. that's why the projector and tablet are hooked up to this box, which is itself attached to a solar panel on the roof. together, they can provide up to five hours of electricity a day, meaning that classes don't have to be interrupted or cancelled if the power cuts out. then, we started using solar power, as it is an easy and natural source of generating electricity. we have introduced a study of generating power through solar energy to our students, and are teaching them the importance and working of it. we also explain to our students that this process will help us, in the future, to generate electricity. this whole system has been provided by the selco foundation, an indian charity with the aim of helping to alleviate poverty by improving access to energy. with this, students can get a better education through audiovisual teaching, and also there is no problem with electricity. so any time the teachers can take

their students to the classroom, they can teach through this medium. selco and other ngos they work with pay for half of the cost of installing the projector and solar system — the other half comes from local schools or local government. how important is the projector? translation: before this project came into useage, we had very few students. but since we have started using the solar power, our number of students has increased in a good way. we have students coming to us from different villages to learn, and not only students — we have other schools coming down to our institute for smart classes. the smart class is a good way of teaching kids these days. they seem to enjoy and learn more than usual. after we introduced smart class, our school stands proudly in the educational sector. we plan to grow larger as the years pass by. cool whoa!

the same system is already in hundreds of rural schools, and they're aiming to add hundreds more this year. and it's notjust key for schools — across rural india, businesses can be helped massively by having a reliable power supply. somana is a seamstress who lives a short drive from kundapur. she became the main breadwinner for the family after her father was taken ill. the more clothing she can repair, the more she gets paid. with her old, hand—operated sewing machine, she could fix a couple of items a day. but thanks to the solar panels on her roof, her electric machine can whiz through five or six clothes per day. plus, she has a fan, a tv and a light, so she can work earlier and later. one—quarter of india's rural population lives below the official population line — that's 260 million people whose livelihoods could be improved

by the addition of basic facilities like electricity. and of course, one key way of helping people out of poverty is... ..education. it's always such a privilege to come to a place like this and see how the simplest technology can make a world of difference. that's it from india for the moment. you can see plenty of photos and more backstage gossip on twitter — thanks for watching. see you soon. hi there.

nothing lasts forever, and inevitably there will be some rain turning up as we go through the weekend. all the more reason to enjoy the sunshine while you can. a fantastic scene out there. this was the scene this morning in sandwich in kent. at the other area of the uk in the west of scotland, this was equally fine and sunny. this shot from argyll and bute. whereas the onshore breeze is keeping it bracing a the kent coast, it is much warmer along the north—west, some of the highest temperatures along the west of scotland. most places somewhere in between, low to mid teens. warmest further west. a fantastic day just about everywhere. warmest further west. a fantastic dayjust about everywhere. this evening things will turn cold quite quickly. if you are heading to the football, take a few layers. just as we saw last night, it calls off quickly once the sun goes down. changes in the weather as well,

areas of cloud and mist drifting in from the north sea. misty and murky across eastern england in particular. a cold one again, single figures quite widely as we have seen over the last few nights. touches of frost where it stays clear along the north—west. temperatures will bounce back again, sunshine first thing in scotland. more cloud in the sky in the east. some areas of fog, too. watch out for those. patchy cloud further west, wales and the west country, but it should be a sunny start of the day tomorrow morning, 8am. and the best of the sunshine tomorrow probably will be across the south—east quadrant into parts of the midlands and across the bulk of scotland. in between, a bit more cloud around, particularly across parts of north—east england pushing into south—east scotland. but we can't complain, another fine day for many of us. temperatures doing well, warmer than today across the south—east, possibly as high as 17

degrees. if dry start, but it does turn wet with time from the west, some of the rain quite heavy. but with the sunshine it will feel pleasa ntly with the sunshine it will feel pleasantly warm. from monday into tuesday, areas of rain pushing in slowly and erratically from the atlantic. the first one bringing some charleroi rain, hit and miss showers across the more southern and western areas as we go through the date —— showery rain. it should stay quite chilly in the east coast of scotland. despite the risk of a shower in the south, it. feel pleasa ntly shower in the south, it. feel pleasantly warm. keep the weather watcher pictures coming in. —— it will still feel pleasantly warm. good afternoon. the home secretary, amber rudd, has said that the government will not shrink from taking action to remove materialfrom the internet that could help terrorists. ms rudd also said the security services needed access to encrypted material on platforms such as the messaging service, whatsapp, which was used by the westminster attackerjust before he killed four people last wednesday.
