the measels vaccine. the measles vaccine. it comes after two universities in california declared a quarantine to try and contain a measles outbreak. students and staff at ucla and california state who've had contact with confirmed cases have been ordered to stay at home. sri lanka's prime minister has told the bbc he did not receive the warnings of an impending attack, before the easter sunday bombings. ranil wickremesingha admitted there had been a serious breakdown within government. libya says it has agreed to extradite the brother of the suicide bomber who hit an ariana grande concert in manchester back to the uk. severe flood warnings have been issued in mozambique after cyclone kenneth, the second in as many months, hit the coast. it affected thousands of people.

have a great weekend, reged will be here at 2am, but now it is time for backlick. setting the record straight. lunar cities, and flying elephants. possession of illegal drugs comes with consequences. and until recently, americans caught carrying marijuana could have earned a conviction. but now, recreational use of the drug has been decriminalised in some states, and

those previously convicted can ask for their records to be expunged. the problem is it has been a slow, lengthy and expensive process, forcing less wealthy individuals to have to live with their criminal records. but now, and artificially intelligent algorithm is helping those who want to wipe the slate clea n. those who want to wipe the slate clean. dave lee has been investigating. anthony turner co—owns a tiny cafe just outside the city of los angeles. it is a remarkable turnaround for a man his teenage years left him with a number of convictions, that eventually saw him sent to prison for 12 years. some of the charges were related to cannabis and many years on, his criminal record still greatly affects his daily life. if you have been convicted of a crime in the cou nty of been convicted of a crime in the county of los angeles in the state of california you can't get a dog walker ‘s license, you can't fly a drone. i can never drop kids. my son

at 15 years old, i can't coach his little league team because i am a felon. on the weekends anthony runs what is known as expungement clinics, where members of the community can go to get free assistance in removing or reducing their criminal record. this one is funded by a new law that californians passed in 2016 that made cannabis legal for everyone in the state. as part of that law, people who were convicted of marijuana offences that would no longer be illegal can now apply to have them scrubbed from their records. clinics like this of course are vital but they are also really inefficient. people have to come to the building, they have to meet with lawyers who are working for free over the weekend, and have to fill ina bunch over the weekend, and have to fill in a bunch of forms, which takes a long time. that's why in san francisco they have been working on a way to take this entire process and make it automated. code for

america is a non—profit organisation that rings a silicon valley thinking into government technology. engineers here have created an incredible algorithm that is able to quickly scrape past marijuana cases and automatically find criminal records that are eligible to be expunged. the estimates are it takes an attorney between 20—30 minutes to review a criminal record. in some insta nces review a criminal record. in some instances it can be 15 minutes. in any case, that's one record reviewed in15 any case, that's one record reviewed in 15 minutes. leveraging our technology, the da can review thousands of records in just a couple of minutes. in an unprecedented and groundbreaking move, the technology was adopted by san francisco's district attorney. ina san francisco's district attorney. in a matter of minutes, 9362 eligible cases, dating as far back as 1975, were identified and will $0011 as 1975, were identified and will soon be expunged by a judge. we created this war on drugs, we harmed

many communities throughout the yea rs, many communities throughout the years, andi many communities throughout the years, and i am talking about the criminal justice system, years, and i am talking about the criminaljustice system, society in general, and i feel that criminaljustice system, society in general, and ifeel that we have an obligation to write that wrong. so this is a process that i felt was important to reduce the marginalisation we have created.- code for america there is hope that this type of technology can be applied not only to the justice system to other areas where americans, particularly poor americans, particularly poor americans, need help fast. we have got a lot of people in the country right now who need a real safety net, they need to get bounced back when they hit a hard spot and they need the criminaljustice system not to pull them down into a cycle of what can become persistent poverty and incarceration. earlier this month los angeles county amounted —— announced it too well begin using code for america's algorithm. it is expected that as many as 15,000 people in this region alone might have their records clear. having

certain things on your record closes doors to more opportunities, and by expunging them it might reopen those doors. i want to get this off, get clean, do what i have to do and have a better life, i guess you can say, than the one i do now. it makes me feel a lot better than i am not a felon. it is not a complete solution, campaigners say, but it is being seen as one major step in the right direction. courts are overwhelmed, judges are overwhelmed, pas are overwhelmed, and these algorithms can actually streamline that process, they are reading 500,000 lines of data in under 90 seconds. we live in a technological age, this is the way that we are supposed to be doing business, and if it streamlines government, saves taxpayers money and makes us safe? it isa taxpayers money and makes us safe? it is a no—brainer. having a criminal past is complicated, and controversial. no algorithm will be able to solve the wider societal disagreements about how to handle those who break the law, even laws

that no longer exists. not everyone believes criminal records should be removed. i say to those who feel but it is tough luck... what they should do is look into themselves and ask themselves, would they have wanted to be forgiven, have they ever asked for forgiveness, because that is what you are doing with society. you are asking not just what you are doing with society. you are asking notjust forested —— specific person's forgiveness, you are asking the world to forgive you. that was anthony turner talking today dave lee. when was the last time you wrote a letter, actually handwrote one? i know, right? it is all about typing isn't it. we have been looking at away machine learning could help write things for you, in your own script. but is it good enough to fool the human eye? is my handwriting really that bad? yeah, it is. (laughs). meet

hemingway. this little robot is doing something that i hate — writing a letter. but this one is securely special, because it is doing it in my style of handwriting. this is writing in exactly my style. and the way hemingway here learn how to write in my style was i sent this piece of paper and with a sample text, this took me 15 minutes to write, hemingway can do it in two. after sending through my written text the handwriting company scans it and put it through its machine learning algorithm to figure out how i write my letters. so the interesting thing about our technology is we mimic what humans do, humans are unique, every time you write a character it is going to bea you write a character it is going to be a tiny bit different, and we pick up be a tiny bit different, and we pick up on those nuances, so be a tiny bit different, and we pick up on those nuances, so oui’ up on those nuances, so oui’ technology up on those nuances, so our technology will learn how you do those and will also mimic all the

variation and generate more on top of it. it is notjust printing the words on paper, it is applying pressure at certain points where i apply pressure. it is being able to do that. the g, i do that without a curl at the bottom, so does this. it has got it down to a tee. this is wicked, look at that. it's all very impressive, and even if i am right underneath the robot's lines, it is very similar. there are little flex of the camera that set mine apart, why would anyone want a handwritten letter nowadays? it might seem a bit counterintuitive, but you get so many e—mails a day, and you barely read half of them. it is about cutting through that noise and adding the personal touch. so we work with big political organisations, these send them out, hotels use it writing a personal touch, or maybe even your exams. to see how convincing this robot really

is, i have brought in graphologist adam brandt to see which is which. the bottom one is written by a human being. the top one is mechanical. 0h! being. the top one is mechanical. oh! yeah, that is me. was it easy to tell which one was which? it has got the spacing right, it's got the angles right, it has the form right, what it is fundamentally missing is the fluency. the little neck there and there. what can you tell from my handwriting about me? there is some lovely things going on here, the sensitivity, the fluency, the need for information, the mental enthusiasm. does it mean that? everything you can tell with my handwriting you can tell from theirs? you can tell a lot from theirs, but in terms of actual identification, it lacks a soul. is there potential for misuse as it currently stands? there are security problems clearly. but it is too easy

to pick up the fact that one is mechanical and the other is by a human being. you are the first ever person that has been positive about my handwriting. the handwriting company plans to improve the system so in future you can print your handwritten letter that home, tell your smart home assistant to write something up, and even write with a particular emotion, like light and flowing for happy, and intense pressure for angry. but until then it is cursed with my cursive. hello and welcome to the weekend tech. it was the week that the launch of the samsung bendable galaxy fold phone was delayed after early reviewers flipped out over fa u lty early reviewers flipped out over faulty display screens. google alphabets subsidiary wing is flying high, becoming the first drone delivery service to be certified by the us federal aviation

administration. and the uk government has reportedly approved the supply of some equipment from chinese company huawei for use in the new 5g network. some ministers have raised concerns about the decision and its effect on national security but huawei has consistently denied that its work poses any risk of espionage or sabotage. vodafone was the uk's worst mobile network providerfor the ap are was the uk's worst mobile network provider for the ap are in a row according to a consumer group survey. vodafone issued a statement apologising to customers, saying they are working hard to understand they are working hard to understand the issue. tesla has reported a loss of over £500 million for the first three months of the year. it is also opening an investigation after this video appearing to show a model s a vehicle exploding in shanghai was shared on a chinese social platform. and finally a trio of autonomous roberts are floating in a most peculiar way, doing astronauts was chores in space. these are astro

bees spent to the international space station where they will be busy, i bet they wish they were up there with buzz aldrin. the year is 2040. welcome to moon valley. the newest city in the universe. home to 1000 people, builders, engineers, farmers, doctors and every year, over 10,000 more come to visit. sounds great, doesn't it? which leaves me with just one important question. how on earth did we get here? moon valley is the vision of someone we have met before. japanese country — my company ispace were one of the

companies competing for the google x prize which offered prize money for those able to land on the moon by march 2018. no—one managed to make it in time but many projects are still ongoing. the israeli team recently reached the moon but crashed into the surface. and as i found out when i visited their new headquarters in tokyo, ispace has also not given up on their ambitions. in fact they have expanded them. we have already made a completed rover, so we have moved on. ispace has moved on to put -- secured extra funding to put japan's second land on the moon. the first one will orbit the moon in 2020, and the second in 2021 will land and deployed two rovers onto the lunar surface. this is the control station for the rover. you have all your

readouts here, one camera —— what the camera can see here and these other control units, they are just off—the—shelf modelling —— modular units which seem to stick together like this. you have your speed, the distance you wanted to travel here, the direction you wanted to go there, so you set all those para meters there, so you set all those parameters up and then you press the big button there and the rover does what you asked it. then as long as you have not put it down a crater, you have not put it down a crater, you can do the next step. i hope they put some markings on these controls before the mission. as with all space projects, the first few missions will take small steps to test their technology, but all this extra investment is probably due to what ispace plans to do next. so there is a lunar cave? and you are going to go towards the entrance of the lunar cave? yes. what is in the lunar cave? this is a new discovery, very recent. we still don't know

what is inside. it could be anything! but it is properly going to be rocks? yeah. (laughs). it has recently been discovered that they could be a network of lunar underground tunnels that were once filled with a lover, and that these lava tubes could be accessed through caves or skylights at the bottom of craters. these permanently dark cold areas could contain ice, and ispace plans to use two rovers tethered together to go find it. by using many network robots to locate and then mind the ice, ispace is proposing to use electrolysis to mass produce rocket fuel, this could create a whole industry on the moon which could then be used as a base to reach further into the solar system. we believe that the moon is going to be the steppingstone for

further space development. and in order to create such a world, we need to create an economy in space. even the first steps are fought with faculty. for example, those first rovers, should they successfully reach the moon, will have to work quickly. a lunar day lasts 14 earth days after which there are 14 earth days after which there are 14 earth days of darkness and temperatures so low, but they won't survive until the next dawn. but when it comes to space, these sorts of challenges that pioneers relish and they certainly haven't stopped ispace from shooting for the moon. now then, blockbuster film from shooting for the moon. now then, blockbusterfilm season is fast approaching so we thought we

look at the amazing effort that went into creating the world of one of the big children's films of the year, dumbo, tim burton's reimagined ta ke year, dumbo, tim burton's reimagined take ona year, dumbo, tim burton's reimagined take on a disney classic with some of the individual names took 36 hours to render. and now, introducing our world —famous flying elephant. i think initially when i came onboard, mike lucas was, what's dumbo going to look like, what are the practical considerations as well as the design considerations, how does tim really want to realise him asa does tim really want to realise him as a character? even though tim wanted something that was completely photo real, his unusual design wasn't going to sit well within a perfectly real world so we chose not to shoot location, everything on stage, control the lighting in the set design, it was important we created this beautiful downtrodden character for the movie with the sort of unusual proportions but he lived in a world that was equally

designed to suit his character and look as well. dumbo's animation is incredibly subtle and contained in most of his emotion is read either through his eyes or a subtlety in the body language so the icing quite a lot of work to sort of find the look and while we were filming, we do everything we can to make sure we get as much in camera as possible and the suit is provided for the kids to stroke but to make that interaction work, we added cga on top of him so they are brushing his hands, it's something to knock off when we first meet dumbo and he tumbles out of the train carriage, we had a starting point from a stunt performer rolling down the ramp but ultimately we had to create a large volume of hay for him to interact with and slide off his head and body. similarly, water interaction, we did a combination of generating a

lot of computer—generated foam and water elements to sit over our dumbo and a numberof water elements to sit over our dumbo and a number of practical elements against foam elements, luck, which we could then add to in the final process. welcome to the medici family circus where anything is possible. not just family circus where anything is possible. notjust dumbo but the aduu possible. notjust dumbo but the adult elephant in the show, they all require an extensive rigging process so the animation team, they firstly have a really good skeletal structure that they can move the joints around and allow them to move as naturally as possible but there are also all the muscles on top of the skeleton and the skin, which all has to interact, one of the key things we wanted to make sure we did was to really capture the subtlety of motion you get an elephant skin

which is incredibly loose and stretchy, the way it expands, it creates lead to different patterns of wrinkles and some of the details really important to capture and we ended up having to embark on a whole new way of creating a sort of skin simulation for want of a better word. right-wing. check. left-wing. check. perfect take—off. word. right-wing. check. left-wing. check. perfect take-off. fantastic stuff. now then, i've come to east london were i'm about to make my own great escape. hi, welcome to other world. would you like to come with me? looking nothing at all like an episode of black mirror, this is a

virtual reality arcade with a difference. step in one of the 14 pods, put on the guard, and you will be transported to 0therworld. i find myself on an island where i am free to wander about. i'm sliding down the slide. i like the way that you walk in this game. you squeeze your triggers and then you just do a walking motion with your hands. being in your own private pod means the environment is controllable and as you wander into different climates, a rumble pad under your feet and heat lamps and bands which suddenly changed the temperature make this a multisensory experience. you can feel the heat on the back of my head now because i'm facing away from the sun. i do like that. put simply, 0therworld is a way to play many different vr games all in one place. from frantic shoot up to more serene experiences. but instead of

choosing them from a menu, here, you wander the islands, just as you wander the islands, just as you wander around themepark looking for different rides. the idea is that you don't just different rides. the idea is that you don'tjust walk different rides. the idea is that you don't just walk around this landscape, you find these pods and insight each one is a vr game so i'm going into one called space pirate trainer. there are 16 games currently available and in the future, the other world —— 0therworld team will allow you to convert points one in a game into real—world tokens to spend on the barand real—world tokens to spend on the bar and although i think my performance is definitely something that belongs behind closed doors, it's possible share your experience with friends and other pods. i want to know what they're doing and that other pod! now, 0therworld is not finished and it's not locked down. it's in continual development and

the slightly less glamorous workshop just around the corner. we are a lwa ys just around the corner. we are always going to bring improvements or taking away features that people don't like and it's this very fluid development we have an sound box literally around the corner of customers going in and using it all day. with £1 million worth of investment so far, 0therworld certainly looks the part but is one of the first vr arcades in the uk, it's probably too early to tell if it's probably too early to tell if it can keep enough people coming through its doors to keep things afloat. i think vr can be good in a limited sense in the home but to gain the full experience it's like going to a proper cinema and that's what we're trying to do, we are giving people the space in which to play and is well we are up raiding the vr experience and that is what those extrasensory effects, the heat the rumble given. it will be massive. oh, my goodness. that's it

from 0therworld. don't forget, we live on social media. you'll find us there throughout the week on facebook, instagram, youtube and twitter @bbcclick. see you soon and if you need me, i'll be in my pod. hello. it will be a stormy start to the weekend for many parts of the uk. in fact, storm hannah has already brought power outages to parts of ireland. the winds have been escalating through the night and evere gales are expected quite widely around the coast and the hills in the west. this is a deep area of low pressure so late into the season,

of course, when the trees are now in full leaf in many areas so we do expect some damage to trees, buildings, power lines and that disruption to transport. there are warnings out there on the website for this storm, mostly for the winds but not entirely because it looks pretty wet as well. we've had one band of rain moving through the night. this next one coming in becomes a slow—moving feature, so with all the cloud around, it's not going to to be a cold start to this saturday morning, but it will be a very windy one. particularly for england and wales where we're expecting severe gales around the coast and over the hills, but inland we're expecting gales, gusts up to 55 miles per hour, which is pretty unusual anyway, and remember, we are very late in the season now. as well as that we've got this rain which will be persistent across parts of northern ireland, south—west scotland, into northern england, north wales, the midlands, across towards the humber and, with that rain and the wind combined, it is really going to feel quite chilly. temperatures barely reaching nine or 10 celsius. to the south, showery, and to north as well

with some good spells of sunshine potentially for western scotland. but some heavy thundery showers around too. and the afternoon may bring a strong wind to northern ireland, south—west scotland and the isle of man as well as north—west england and north wales. it will still continue to blow a gale or severe gale further south. a very windy day, certainly not a day for the outdoors. but the winds do ease through the night, and that's because storm hannah starts to blow out to the north sea. and we get a ridge of high pressure building for the second part of the weekend. it's not plain sailing but i think for the london marathon probably the day of the two and almost great conditions for the runners because it will stay cool, we think, quite a bit of cloud around, i think there will be some brightness coming through, and temperatures will be doing a little better than saturday. however, you can still see this weather front

draped into western parts, so northern ireland and wales and south—west seeing further dank weather. further east we'll have the remnants of our weather front. in eastern areas, a few showers around. a cool northerly breeze will be much lighter. 12—15 looking like our highs. they're a little bit more respectable from the days ahead. then high—pressure starts the new week so it could be a bit chilly first thing monday. a little bit of mist and fog around, but we'll start to see this weather system winding itself to bring some rain into the west. an unsettled picture into early next week.

this is bbc news. i'm reged ahmad. our top stories: a race against time. president trump urges people to vaccinate after measels outbreaks force two universities to quarantine staff and students. tension in sri lanka, as large amounts of bomb making equipment are found in the hunt for those behind the easter sunday attacks. the prime minister tells the bbc he wasn't aware of the early warnings. what do you do when you're out of the loop? you are talking about not being in the loop? what the prime minister. you are number two of the national security council. driving further inland, cyclone kenneth hits mozambique with strong winds, threatening more floods. and a new exhibition opens exploring the life and work
