trapped in the last part of mosul under islamic state control. iraqi forces say the remaining is fighters will be defeated within days. the country's prime minister says the city will be liberated within a week. rescuers in china have been using bulldozers and diggers to try to find survivors of the huge landslide in sichuan province. more than 100 people are missing and at least 60 homes were covered by mud and debris after days of heavy rain triggered the collapse of a mountainside. 3a high—rise buildings around england have failed fire safety tests. the blocks, in 17 local authority areas, were the first to undergo urgent checks. it's believed the type of cladding used on the grenfell block caused the blaze to spread rapidly. those are the latest headlines. now on bbc news, it's click. this week... driving arizona. teaching tanzania. and clowning in california.

la la la los angeles. a city of many sights. there is the movies. the beaches. the high life. and in between each of them... ..a lot of this. with hardly any rail alternative, the traffic here drives the locals to distraction. it's led some of the bigger thinkers to suggest radical alternatives. electric car and space travel guru elon musk has even started digging a tunnel.

he envisions an asimovian network of car— and passenger—carrying tubes underneath cities in the future. how boring! meanwhile, back in the almost real world of marina del rey, a more modest way to reduce traffic — two electric cars that belong to a whole apartment block. envoy operates a closed car—share system. the vehicles can be booked out by residents only and used for up to three hours at a time. now, this is not a car that you would use to drive to work and back because you'd end up paying for and hogging it for the whole day. this is much more a car that you would use for convenience — popping out for the occasional errand. yeah, we believe that if it's a two—car household, we can hopefully reduce that to one. experts say for every shared car, it takes 11 vehicles off the road. so we're working with developers on communicating

that with policymakers in the city, saying if we include car sharing within communities, we should be able to reduce our parking requirements on new developments. envoy is just starting out and hopes to roll out into new areas in southern california and then new cities across the us by the end of the year. and further into the future, aric would like to see shared vehicles available wherever there are large groups of people. now, for some, this kind of thing is going to be an interim stop before we get to fleets of self—driving vehicles cruising the streets, picking us up whenever we want, and no—one has to own a car at all. so, how is that getting on? well, here's mark in phoenix. ride—sharing company uber has been in the news recently for all the wrong reasons. its founder and boss travis kalanick has resigned after coming under pressure from investors following a flurry of public controversies, including complaints of sexual harassment and bullying at the company.

kalanick‘s departure comes after the dismissal of 20 staff who've been fired as a result of the scandals plaguing the start—up. whilst uber‘s corporate culture may be in disarray, it is pressing ahead with an ambitious tech project. if you've used a ride—sharing app before, you know the drill. you have an app on your smartphone, you push a button and a car arrives, and it behaves very much like a taxi. but, here in arizona, if you push that button, there's a good chance the car that will arrive will be a self—driving car. the sunny university city of tempe, arizona is one of two locations, including pittsburgh in pennsylvania, that uber is testing a fleet of autonomous vehicles. a host of sensors, including lidar and cameras, have been fitted to these volvo suvs. the sensors become the car's eyes on the road, informing systems that drive the car, as well as trying to predict the actions of other road users and pedestrians.

all right, and we're engaged. all things which humans take for granted but are difficult for machines to achieve. i'm taking a ride in a self—driving car. there are, however, two guys in the front seat. what is it you guys are doing here? so, in the drivers seat here, i am monitoring what's going on around me. i'm still technically a driver — being that this vehicle has to be taught what's going on around it. if an event that the car does not know how to react to, that's where i can take over. so you are the safety driver, if you like? i am the safety driver. now, you are the safety laptop operator? so what are you doing here with a laptop? from the laptop, i can monitor a lot of the prediction software, so i can see where the car is going, where the car wants to go, so this is all feedback which goes

directly to all the engineers and they are able to interpret what's going on and improve for the next iteration. so what you're hearing, the car is determining it wants to change lanes, but other vehicles around us are too close, so it decides against it and stays in lane. right now, you see it just change lanes there. over the course of our ride, the driver does take control for a short time, but the majority of the ride is performed autonomously. uber doesn't publicise how often the human drivers takeover however. it's not been plain sailing for this project. injanuary, one of the autonomous cars here in phoenix was involved in an accident. nobody was injured but a self—driving car was left crashed on its side. and a pilot testing programme in san francisco was called to a halt after a row with the california department of motor vehicles over permits for autonomous cars. on top of all that, waymo, the self—driving car company owned by google‘s parent firm alphabet, has accused uber

of stealing trade secrets. uber denies using or receiving stolen technology. thankfully, back in arizona, my ride continues without incident. i'm in a robot car, essentially, that's like something from a science fiction movie. and i'm a tiny bit disappointed. because the car is driving itself without any hassles. this is like any normal cab ride. and uber isn't alone when it comes to self driving testing. the state of arizona is very accommodating, allowing self—driving cars from waymo, ford, general motors and intel on its roads. we're several years away from fully autonomous cars taking to the highways yet, and it seems that the road to fully self—driving vehicles is still a bumpy one. some american freeways have carpool lanes which you can only use if you are carrying more than one person in the car.

the idea is those lanes at least are travelling at a decent speed. well now, they are also planning similar lanes for autonomous vehicles and they are calling them ‘hyper lanes.‘ this system will be controlled by a central computer and will whiz self—driving cars along at speeds of over 100 miles an hour. you would use access stations in your local neighbourhoods and once you enter the station, your car will start driving itself and they will launch them onto a hyper lane. after that point, the car would be able to drive itself and you can just sit back and sip your coffee and check your phone. the plan is to use existing highways to create these hyper lanes. customers would pay surge pricing in order to ease congestion and arrive at their destinations as quickly as possible. there are also plans to use the service for parcel delivery and autonomous buses.

however, to put even a test version of this in place is going to cost $12 million per mile. so for the time being, it looks like autonomous cars are going to be stuck in traffic with the rest of us. it's time for this week's tech news and boy, what a week. you thought google glass was dead, but it's not. it released its first update for three years. a us officialfrom the department for homeland security said this week that russian hackers targeted election systems in 21 states during last year's campaign. and netflix has announced two interactive tv shows where you can pick the storyline. they said it was designed for kids, but come on, that looks fun. and could we soon be seeing the queen in a g—whiz? probably not. but the queen's speech outlined plans for petrol stations around the uk to go electric. it's part of a government plan

to push more electric cars onto the road. and more news from the uk's roads this week — driverless cars are being given the green light to begin trials later this year. a collaboration between jaguar land rover, ford and tata motors has been showing off how autonomous cars can talk together to provide real—time traffic information. and what if you could tackle a mario level while out and about? one man has donejust that, creating a super mario brothers level in an augmented new york central park. he created the whole thing for the microsoft hololens, which unfortunately isn't yet available for the general consumer. the abundance of everything here in the us is evident and it's thanks in no small part to having one of the best educated and most skilled workforces in the world. and it is from right here that the xprize in education was born. now, this is a competition that encourages entrepreneurs to use

technic to teach. now the finalists have been announced in london this week and dan will take a look at some of them in a minute. but first, he travels to tanzania to see what's in store for those hoping to offer something new to the next generation. and sitting right behind the pilot, write there! we are travelling a long way from any town or city to visit some of the 200 children in a village in northern tanzania. we are booting up a tablet, the first one. the interesting thing here is that most of these children, about all of them, have not seen a tablet before. but not only that — a lot of them wouldn't have gone to school even before, so the learning process itself is brand—new.

the whole programme is in swahili so the local children can understand. i think they are going to need more tablets! laughter. this is one of about 150 villages in tanzania chosen as the test—bed for the global learning xprize. within a few months, 4,000 tablets will be given out. the challenge — to teach a 7— to 11—year—olds to read, write and do maths over the next year. the most effective app will win $10 million. the prize here, though, will be much more valuable. older children can walk up to four hours to get to and from school. for younger ones like 7—year—old amina, that's simply too far. she's been lucky — she is one of those that's been chosen to take part in the xprize challenge. at the start, she has not seen a tablet before, so she's not used to touching screens. and when it comes to reading, she does not know more than one or two words in a sentence.

butjohn, who is with the project, thinks the tablet will help her eventually to read fluently. back in the capital, dar es salaam, the world food programme is testing solar panel stations that will monitor the progress of each child when they recharge. that way, if a tablet breaks, the youngster can get a new one without having to start lessons from the beginning again. in london this week, 11 semifinalists from seven different countries were chosen from the nearly 200 teams that entered. they will refine their software before the final five are chosen to go to tanzania to start the year—long project with the children. so the problem is that there are about 60—100 million kids who have no access to school, because school is too far. then you have 250 million more who go to school and leave without ever having learned to read or write a word. and these are kids in botswana,

boston, brighton — it doesn't matter. kids go to school all over the world and they go, they don't learn, and why is that? that's the question we are trying to address. you know, in our greatest desire, every single child on planet earth has access to a world—class education in the palm of their hand. every single child has his or her potential fulfilled. that's the dream and it's not a far—fetched dream. it is possible. we are hoping to be back next year to see how the teams get along but for now, it's time to say goodbye. we've brought some biscuits to say thank you and suddenly the difficulties the team will face when they arrive become clear. with just 20 or so tablets per village, there simply won't be enough for everyone to take part. to reduce potentialjealousy, the tablets will be locked to only run the educational software. but everyone wants one. a village mama has been chosen to settle any disputes,

and the scheme's partners unesco will be asking some other important questions about tablets, too. we are doing an assessment of the social and emotional impact of such learning. because we expect quite some criticism from that side. we are engaging with the psychologists, anthropologists, educationalists, to try to understand what does it do to the child? is that an option that is ethical? because children go to school, they are socialised also — it's not only the learning, it's learning much more, to be part of the group. it's just like back at home. now they've got tablets they are not really talking to anybody. this is my first time to see people learning by using tablets. it's my first time. so the scene is set, there are about six or seven

children around each individual tablet and we've seen more. the education department from tanzania is here too looking at this project so there's a lot at stake. it's notjust $10 million, it could be the answer to the whole country's education problems. and even the whole of africa's. virtual reality is no longer in its infancy. so here at this years sheffield doc fest, content makers are trying new ways of grabbing our attention. this is first impressions, were i can see the world through the eyes of a baby over its first few days of life. why is someone putting a toy in front of my face? it's quite unnerving. the trend may seem to be moving towards how far we can go with the medium to make the virtual world feel realistic. in my shoes aims to create a sense of intimacy.

i've been to some amazing places in vr, i've even had some workouts in virtual reality. but one thing i haven't tried yet, which i'm about to, is the idea of it trying to create some sort of emotional engagement. now this is going to require a second player, here i've got 0llie who is willing to take part. very willing. thank you for doing so. first of all we are going to pretend to be strangers, which isn't entirely true, we've met a couple of times. then we're going to pretend we are in a long—term relationship — things are moving fast around here! and thirdly were going to be on a tinder date. say something. i can hear what he's thinking, who wants that on a date? i'm actually the man. i'm a man on a date with a lady. i'm not a murderer. the situation is feeling a bit intense.

that's good to know. no, but you know what i mean. you can meet people online and they can turn out to be murderers. yeah. i'm just saying that i'm not. oh no, get me out of here. i'll hold your hand. do it. she's touching my hand. he likes that, look at that smile. this date is terrible, why are we holding hands? goodness, goodness no, this date is going really badly. 0h, crikey. it was really, really good fun, the experience. and i can see that it is possible to engage you in an emotional way and i think the fact that i could feel that uncomfortable really was quite something. i wanted to get up and leave the date when it got awkward and when you tried to hold my hand, we are acting, i wasjust like no, no, get me out of here! meanwhile here's something else to stir up the senses. with your help to share our story,

we can finally have our lands legally recognised as ours and we can continue to fight these dams. commissioned by greenpeace, munduruku is the story of the indigenous people of the amazon rainforest. and to help make it feel real, a humidifier, heaters, fans and grace the sensory technician with some fragrances to hand, are all around. ok that really smells like a forest, that's amazing, that smell is really good. i don't know why the chair‘s vibrating, i don't know what that means. this project is part of our amazon rainforest campaign and we've been working with the munduruku to try and build solidarity between urban and indigenous populations in brazil, to protect that land where they are facing huge

threats from logging, from hydroelectric dams and from mining. what we wanted to do with the multisensory side of it is really emphasise that sense of presence that you get within virtual reality. it's very difficult sometimes when you can just see something to really feel like you're there. we wanted to make it as vivid and immersive as possible. elsewhere companies are working on the next generation of 3—d sound for vr. this software is developed by a company whose audio optimisation is already used in over 150 million smartphones. the sound is great, no questions about that and i could certainly feel like something was coming from a speaker over there. now this head tracking device which is attached to the top means that if i was wearing a virtual reality headset, then when i turned my head backwards or around, if there was a sound overhead, say it should sound like it's coming from up there. obviously i couldn't test that element but long term that is certainly the plan this software hopes to be able to achieve. whilst the experiences are becoming more real, the kit is still pretty bulky

so you are unlikely to forget that you're wearing it. although maybe some sort of reminder of reality is still a good thing anyway. right, what should we play, what's your favourite game? i think we should do... we should do flags and i'll take you both on. that was lara, and now time for some fun and games with these two clowns. not being rude, they are actually trained circus clowns. but they're also the bosses of a company called two bit circus, and they want to build an enormous high—tech fun house in downtown los angeles. protect that ball. so we are building what we call a micro amusement park. it's a 50,000 square feet entertainment complex dedicated to the future of fun. the future of fun! that's a catchphrase. well, you know, here's the thing.

there is this period of time when kit comes out of the lab, before it's ready for the home, that it's perfect for out—of—home. you know, you can do some vr in your home right now, but it is so much cooler if it's social like this and has environmental effects and all sorts. motion platforms, your friends can play with you. brent and eric have been making high—tech games and showpieces for corporate events for a few years. their planned amusement complex will be a permanent home to some of their greatest hits. along with new experimental experiential oddities being developed by their team of computer scientists, roboticists and engineers. we've got machines that can cut metal and cut wood, we can prototype our circuit boards here, we have people writing software. and the beautiful thing about this place is that at the end of almost every day, there is something new to play with. it is maximum fun. the philosophy here seems to be tinker first, think later.

i don't actually know the point of this game. neither does anyone else here. this is the ultimate play space and a great coming together of people with many different skills. we are drawing on multiple industries. so we have a lot of people from the games industry here. so all of the development that's gone into sophisticated 3—d game engines like unity and unreal, we can put that to work building immersive environments. my background and the background of some others here is in robotics and sensors. and we bring, we come with a completely different toolkit. but the combination of those two things makes programming around here really exciting. but there is still one big build remaining. we are standing right in the middle of our micro amusement park. most of it is going to be a big open space. the kitchen will be in that corner. a 100 seat interactive supper club is going to be over there.

with $15 million backing from companies including intel and japanese ventures, brent hopes that this 50,000 square feet space in downtown la will become the first of many two bit circuses around the world. —— two. you are opening in... february? early, early 2018. ok, i think you've got a bit of work to do. we've got some work to do, it's a little empty, you can see, it will be a lot more fun when we are done. but, yeah, from the moment we break ground to the moment we are ready to open, it's four, five months. well, if they can pull it off this is going to be an incredible space and a perfect excuse for us to come back here in january to see how they got on. ok, that's it for this week, follow us on twitter and facebook for loads more stuff throughout this and every week. thanks for watching and we'll see you soon. hello there, good morning.

things are pretty much back to normal across the uk. we've got low pressure in charge of the weather. we've got that curl of cloud to the north of the uk. that is that centre of the area of low pressure and the closer you are to it the stronger the winds are and the heavier the showers are. so there are some showers to be had in scotland overnight. quite blustery and by the end of the night we will see an area of rain moving into western england and wales. 13, 1a, 15 in southern parts of the uk, ten or 11 in the north. quite a lot of isobars in the charts for sunday as our area of low pressure drifts towards scandinavia. the winds coming down from the north or north—west around that area of low pressure. never a particularly warm direction for us. it's still quite blustery

into the morning across scotland. some showers for the north and west in particular. some eastern areas will get off to a decent start, bright and breezy, as it will be in northern ireland and much of northern england, too. however, from manchester across towards hull, an area of cloud and a little bit of of rain first thing. there will be some wet weather for wales and the midlands. east anglia and the south—east starting largely dry if rather cloudy and breezy but relatively warm, 17 degrees in a few places. further west, we are likely to see some rain and some of that may affect glastonbury for the morning. it's not overly heavy but some rain nevertheless. through the day, it's a north—south split, with the southern half of the uk fairly cloudy with some rain. certainly not a washout but some wet weather in the wales, the midlands and east anglia by the afternoon with a fair bit of cloud either side of that. further north, sunny spells, scattered showers, 15 degrees in glasgow, 22 or 23 in the london area. of course it's the last day of glastonbury already. a little bit of rain early on but that should clear away and it gradually dries up, brightens up into the afternoon and evening. 17 or 18 degrees but also that noticeable breeze,

and a breeze, too, at queen's club for the finals, but it should be fine and dry, if on the cloudy side. top temperature, 21 degrees. by monday, a lot of dry weather for the eastern side of the uk, some sunshine and warmth for the south—east. an area of rain pushing its way into the north and west. question marks about the timing of this so keep an area on the forecast but at the moment it looks like heavy rain across northern england, southern scotland, monday night into tuesday, and tuesday looks quite wet for the western side of the uk, the north as well. that bit drier the further east you go. quite warm as well. but under that rain it's not going to feel all that great. it's looking fairly unsettled on tuesday, and i think for much of this coming week, it will be quite unsettled with spells of rain which could be heavy at times, and to go with that there will be a noticeable breeze and not much sunshine in the forecast. hello, i'm tom donkin.

welcome to bbc news, broadcasting to viewers in north america and around the globe. our top stories: fears for up to 150,000 civilians trapped in the last part of mosul under islamic state control. iraq says the remaining is fighters will be defeated within days. this is the old city area, it's the heart of the battle, and if you look around here you get a real sense of how fierce the fighting has been. the world's worst cholera outbreak. a un warning about yemen as the number of cases passes 200,000. the desperate search for survivors after a massive landslide in china's sichuan province. more than 100 people are missing. 3a high rise buildings around england have failed fire safety tests following the grenfell tower disaster, with hundreds more still to be assessed.
