donald trump has withdrawn his healthcare bill. he was forced to abandon his plans after being told he did not have enough republican support to win a vote in congress. some opposed his alternative to obamacare which will now remain in force across the us. the british police have appealed to the public to help uncover the motivation of the man who killed four people in the man who killed four people in the attack in westminster on wednesday. detectives are still trying to establish whether or not he acted alone when he drove into pedestrians before stabbing a police officer. marine le pen says she would can set a lifting sanctions on russia if she were elected. the national front leader met vladimir putin in moscow and said he was not trying to influence events. and now one bbc news, click. there will be dancing, there will be

singing... sort of. driving in india is an experience. the roads are crammed and the horn is on the present and the rules are... well, they are 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 is not true. any people choose to travel by train instead. if you think that is any less intense... think again. yeah, about those rules... the central station isa those rules... the central station is a massive heaving hub collecting the city to the north and east of india. 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 not just and here is the interesting part, this is notjust about this station. along the railway tracks live 115,000 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 this man, 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 then, relatively speaking, power is a challenge and

the entire country had to walk for, there is only one place. that is awry waystation. 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 do this was to see if we could provide an open internet, completely open with access to the entire world. the way the web was designed. so, there isa way the web was designed. so, there is a fibre network rolling out from train stations like this to the vast rural areas of this enormous country. and david hopped on a train to find out what effect that has happened having elsewhere in india. it is hard not to be romantic about the railways of india. british

colonial rulers laid tracks to control shifting resources, mostly out, and prising open markets. now it is about moving people, millions a day. and thanks to optic fibre, data. i took the train to a station to investigate. it has proper broadband and it is free. people are filling their booths. apart from some controversy, at this station where people were using free wi—fi to download ha rd—core where people 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 the station every day. i use the

internet for work and entertainment. for a studentjournalist it means she can keep tabs on breaking stories. early in the morning, the world changes like... so many things change. i 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. this man runs a tea stall on the platform. he makes more money 110w the platform. he makes more money now that his customers and make online payments to him.|j now that his customers and make online payments to him. i use the wi—fi when my four g signal does not catch. when that does not work, i use wi—fi, especially when a customer pays digitally. i needed to confirm i have received the payment. a digital payment worth about 30% of my takings. this is music to the

yea rs of my takings. this is music to the years of people managing the ra i lwa ys years of people managing the railways of india. an industry that i’u ns railways of india. an industry that runs at a loss. they think that high—speed wi—fi could be a good pool frustration might jaipur. they planned to build a huge concourse and attract retail and services business. 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 tourist hub of high repute. people come out here from all parts of the world. and when you have a huge concourse it is an area where you can have shops and entertainment. for google, more people online as 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. go and welcome to the week in tech.

it was the week that laptops and other electronic devices larger than cellphones were banned from caverns on us and uk bound flights, leaving from some african and middle eastern countries. they start up hopes to be able to provide flights from london to paris by electric plane within ten yea rs 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 ofjust new york could be back with flight times of just three new york could be back with flight times ofjust three hours and 15 minutes. after the start—up, boom supersonic gained $33 million in funding. an unarmed starved convenience store has opened in shanghai. created by a swedish company, the always open never staffed by a human shop requires using an app to enter, scam purchases and pay. nasser is

creating an origami inspired robot that can flatten itself to fit into small spaces. the robot 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. research have been examining how the ball‘s path can be tracked, predicted and matched up in its virtual view. or... you could just play without the heads sect. —— headset. you may have noticed by now that the roads here are in india are... well... utterly chaotic. 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 all cabs, the biggest taxi reeling app, the uber of india as you will. or as they say, uber is the all of india. founded back in 2010, three years before uber launched in india, they have taken full advantage of their head start. they have historically been number one in india but the uber has said that that is changing. it looks like the battle for the pat

cash in india is onlyjust beginning. these are the head offices in silicon valley of india, bangalore. this is employee number one. india is not designed to have many cars. what are the specific needs of your customers and drivers? we made a platform that is notjust about cabs but about many other things in india. supporting bikes, electricity, . .. things in india. supporting bikes, electricity,... different things in india. supporting bikes, electricity, . .. different transport options. so that brings an a lot of options. so that brings an a lot of options for users. they 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 drivers to pay by cash. do brew is coming into the indian market. how are you different from them? how will you stay ahead? there isa them? how will you stay ahead? there is a fundamental difference in the way we operate. we believe in what we wa nt way we operate. we believe in what we want and not what we have. uber plugging in things have worked well elsewhere. 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 clark, like when theyjoin the service for training or if they have a problem, an issue with their wages, for example. but they do not actually employee any of these people. they call 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 they are responsible for maintaining theircarand they are responsible for maintaining their car and paying for fuel. they are responsible for maintaining their car and paying forfuel. 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, all really, really wa nts despite this, all really, really wants drivers to drive. a lock. so much so that there are carrots if you stay on the road and sticks 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. we need to lea pfrog for a billion people. we need to leapfrog all sorts of impediments and we need to promote share mobility, sustainable options, our government is focusing in a big way

on all vehicles. ola is one of the most successful start—ups to come out of the education sector. these top—level universities are dotted across india and they are the driving force behind many of india's technology successes. getting into iit isa technology successes. getting into iit is a 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 my first appointment is at the olympic—sized swimming pool. although it's not me who's taking a dip... this is matsia, named after the avatar of vishnu, which takes 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 make sounds, and recognise, manipulate and grab objects. the team tell me it might be used to find flight recorders from aircraft, although they're also pitching it to the military to fire torpedoes. the project is in its fifth year, and the team leader here tells me the work is hard, but can be massively wide—ranging. tells me the work is hard, but can be massively wide-ranging. what we are giving everything you want... like a race carg, or a satellite. brilliant! is matsia is one of 100 projects that have been supported by iit bombay‘s society for innovation and entrepreneurship since 2004. it's 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—deeeee—ddoooooo. noises with my face... doooo-deeeee-ddoooooo. very good. there you go. you got some score over there. "some score." if there you go. you got some score over there. "some score. " if you there you go. you got some score over there. "some score." if you do 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... 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 don't evaluate your singing, they just have input — you open your mouth, you get a good rating. we do a multidimensional evaluation of yoursinging on a multidimensional evaluation of your singing on different aspects of music — pitch, rhythm, dynamics,

timing... you asked for a hard exercise! ehhhh—oooooh... eeeeeh—eeeeee—eeeeehhh. .. echoing if my singing went right through you, i've got something upstairs that will really cut to the bone. the algo surge 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. bones from just two two—dimensional x-rays. i can imagine, after a lot of experience, a bone — if ijust look at an x—ray, i can imagine it in three—d — can we do the same thing with computers? a virgin can do it, because he has learned a lot of correlation between x—ray data and the bone he sees in the surgery. we use the same logic to develop the software. we have a machine—learned

algorithm which has learned the three—d of bones across the population. we have created a lot of models from ct scan, and we use this asa models from ct scan, and we use this as a kind of database, and we create an algorithm to understand that database in a particular array to predict x—ray images. database in a particular array to predict x-ray images. these three-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 special, specific instrumentation which uses the bone surface in three—d, and it is like a negative of the three—d bone surface. if you make that part and print it in three—d, and put it on the real bone, it will exactly fit. so what we do is, we use that concept to cut, to make surgeon cut more rapidly, 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 cutting tool. two x-rays are, of course, cheaper than a full three—d ct or mri scan and, once again, it means patients can be assessed who can't get to a fully kitted hospital. there'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 mirrors on the braille readt here, and you can control the navigation using up and down buttons here. well, this is a prototype braille display called braille me, which works in a slightly different way. the braille displays currently existing on the market are based on keiso—electric technology. because

of that, the cost for these devices are around are $2,000 to deloo 3,000 each. we developed a completely new technology based on magnetics that are able to reduce the cost by 10 times. so we can sell it to the user ata times. so we can sell it to the user at a price point around $300—$400. this machine needs to move for at least 10 million cycles of movement, it needs to be quiet, have power, and needs to be very precise. that is the challenge. this is the andumen irdu primary school in calcutta. there are 155 kids here from grade1 calcutta. there are 155 kids here from grade 1 through to 7, and a whole bunch of dedicated teachers. and this is how they start their day. singing over in virjaya nijak‘s classroom,

things are a little more serious... so, at the back of the projector, there's a 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 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. transthis is a valued school. earlier, it would be difficult to teach because of power cuts. 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 01’ 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 studiy 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 hoping to alleviate poverty by improving access to energy. with this, they will get a better education through audiovisual teaching, and there is no problem of electricity. so time 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 governments. how important is the projector? translation: before this project came in to use it, we had very few students. but since, we have started using the solar power, our number of stu d e nts 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 part? 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 not just

and it's notjust key for schools — across rural india, businesses can be helped massively by having a reliable power supply. somana is a sea mstress reliable power supply. somana is a seamstress who lives a short drive from kindapur. she became the breadwinnerfor her from kindapur. she became the breadwinner for her family after her father was taken ill. the more clothing she can prepare, the more she gets paid. with her old method, she gets paid. with her old method, she could fix a couple of items per day. but thanks to the solar panel on her roof, she can whiz through five or sext per day. plus, she has afan, a five or sext 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 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. we live at: thanks for watching. see you soon. hello. there will be some chilly nights this weekend. there will be frost for some of us as the weekend begins, but by day, it's sun, sun, sun. what a glorious weekend if you're a fan of blue skies. high pressure right across the uk.

the weather ingredients this weekend, because of high pressure, as you might imagine, it's going to be settled. there will be some warm spring sunshine around, but for some others there will be a noticeable breeze. we will need to shelter from that to enjoy the warm sunshine. some chilly nights with frost around. looking at the temperatures as the weekend begins, these are the urban readings, but away from the towns and cities in the countryside we will see those lower readings on the thermometer. in parts of northern england, northern ireland and scotland we'll see frost. many of us will have widespread frost on ground and grass. a few patches of fog in parts of yorkshire, lincolnshire, the midlands and parts of wales. that shouldn't last too long into the morning. an exception to the settled weather will be in the northern isles. more cloud around on saturday, especially in the shetlands. outbreaks of rain at times, mostly on the light side. as day breaks you can see the extent of the sunshine to begin with, but hints of either mist fog patches, or low cloud, to begin with, through parts of yorkshire, lincolnshire, the midlands and into wales.

it should not last too long. by mid—morning that should be gone. look at the strength of the wind in east anglia, south—east england and along the south coast. if anything that may be a notch up compared to what we had on friday. quite a windy picture for some of us. you will need to shelter from the easterly wind to get the best of the warmth from the sunshine. the blue sky continues for the majority of the afternoon. that warmth will be felt, especially where the wind is right down the western side of the uk, 15 or 16 celsius. saturday, a fine evening, but a chilly night. a touch of frost, especially in the north. remember, on saturday night the clocks go forward an hour, the beginning of british summer time. nothing to do with the weather, though it sounds good. great for night workers, and great if you want your light longer into the evening. here are the sunset times on sunday. there will be some sunshine around again on sunday for the vast majority. maybe just a bit of cloud to some eastern parts of the uk later in the day.

still that breeze to the south and still sheltering from that to make the most of the sunshine. for the vast majority, the weekend will have a blue sky note. whatever you are doing this weekend, enjoy that, and enjoy your weekend. welcome to bbc news, broadcasting at home and around the globe. my name is lebo diseko. our top stories: a humiliating defeat for president trump as he withdraws his health—care bill because he could not get enough support for it to pass congress. a lone wolf, or did he have helped ? pass congress. a lone wolf, or did he have helped? british police investigate what motivated the westminster at hacker. —— attacker. hello, and thank you forjoining us. president trump has withdrawn his health—care bill before congress got a chance to vote on it after it
