control legislation that had just been signed into law in florida. the nra says the law, which raises the legal age to buy guns, violates the second amendment, the right to bear arms. president trump has tweeted that a deal with north korea is, as he put it, "very much in the making." earlier his spokeswoman said a proposed meeting between the president and the north korean leader, kimjong—un, would not happen unless washington saw concrete steps or actions by pyongyang. an aid convoy has successfully unloaded its food supplies in the rebel—held enclave of eastern ghouta in syria. it was the third attempt this week to get lorries into the area to help trapped civilians. the red cross hopes to get medical supplies into the area next week. coming up injust over ten minutes on bbc news, it's newswatch. but first, it's time for click. as international women's day was marked this week, it brought with it further focus on the many issues still to be faced in bringing about true gender equality in all walks of life.

the technology industry, of course, has its own issues, as we'll hear later. silicon valley's culture and its treatment of women raises a lot of questions. but tech can also be a force for good. it's beenjust six months or so since the me too movement gave a voice to so many women around the world, who used social media to expose just how widespread sexual harassment and assault is. many women feel that reporting sexual assault can also be really traumatic, and the experiences of some women in silicon valley have spurred them to create something that may make thatjust a little bit easier. sumi das has travelled to stanford university to meet survivors of sexual abuse, and the creators of callisto. every tattoo tells a story. for stanford university studentjacqueline lin, the story is bittersweet. lin was one of 50 sexual assault survivors invited to share the stage

with lady gaga during the 2016 oscars. while we were rehearsing, i remember at one point we were all crying and hugging each other, and someone just said, "we need to get a tattoo to commemorate this and to give us strength." something to look at when you are feeling down, and to know that you're not alone. lin says that a few days after she was assaulted by a friend in 2015, she told the title ix office, which investigate sexual misconduct. i decided to report because i didn't want him to do it to anyone else, and later i did find out that he had done a lot of... a lot of harassment, stalking and also assault on someone else. what was that experience like? it was awful. my gpa dropped down, and i was fighting with the school back and forth every single hour, every single day. lin, now an activist, wants greater transparency in the adjudication process. they're trying to cover up

the number of sexual assault that happen on their campus, because that makes your university look safer. it's better for your public relations. stanford told click: stanford changed its title ix process in 2016 and has begun reporting case numbers. in the us, one in five women is sexually assaulted while in college. i was sexually assaulted by a friend. over a year after that happened, i decided to report my assault, and i ended up finding the process of reporting to be more traumatic than the event itself. feeling not believed by the people who i thought were there to protect me was incredibly destabilising. jessica ladd's ordeal spurred her to create callisto, so survivors would have a way of reporting sexual assault. they can, one, just say what happened to them

with a timestamp, doesn't have to go anywhere if they don't want to. two, report electronically to the authorities at their school. 0r three, just say what happened to them for now but report electronically if someone else names the same assailant. you can think of callisto as an international information escrow agency. it holds onto records and only alerts schools when there's a match. students often report to protect others. this matching feature helps do that by detecting repeat offenders. people might use different names, they may look different. how do you make sure you've got the right person? we ask victims to put in notjust the name of their perpetrator, but also a series of unique identifiers. currently, facebook profiles are used to match. some students want more ways to id, and callisto may add mobile numbers and e—mail addresses in the future. 12 us colleges use callisto. the university of san francisco was the first. we knew students weren't reporting. if you look at our numbers from once we first started with callisto,

three years ago, to now, there is definitely an increase in reporting. callisto allows for our students to write what happened, to write about the incident. and sometimes just writing your perpetrator‘s name gives people power. seeing the need for callisto, shanta katipamula led an effort to bring it to stanford. it is just available 21w, and they have seen spikes in usage wlucbmeansthai: wecguld. .. .. . .,.. .... that gives them a better sense of what is happening in that store

record, what type of years are assault occuring, what type of assault is it? is it involving alcohol, is it not? what class years are involved? others are also working to make reporting less daunting. the spot app creates a record from the user's conversation with a chat bot, while all voices will let them report electronically. lin isn't sure electronic reporting would have changed her was handled, but she see the potential. what i think callisto is great for is to track perpetrators. if they decide to apply for grad school or transfer schools, i think that's where this can really come in and have a very powerful effect. as we grow, we want to create one system, one database that allows us to track any perpetrator, even as they move through space and time. which would give survivors a way to find out if their assailant is a repeat offender, something ladd says she wonders to this day. hello, and welcome to the week in tech.

it was the week that sony blocked the videogame super seducer for being released on the playstation 4. it's been criticised as too sleazy and for promoting toxic behaviour. dyson announced it won't be making plug—in vacuum cleaners any more, they'll be developing their cordless battery range. dating app bumble has banned members from posing with guns in their profile pictures, though an exception is being made for military and law enforcement officers in uniform. solving in three, two, one. and a robot managed to solve a rubik's cube in under a second. blink and you'll miss it. here it is again in slo—mo. it was the week that mobile companies three and vodafone came under investigation over the way they handle data on their network. 0fcom's looking at whether they're intentionally slowing down internet speeds while customers are abroad. internet artists invaded new york's museum of modern art, transforming the jackson pollock room into their own augmented

reality gallery without the museum's permission. the project was called hello, we're from the internet. and finally, flippy the robot has been working at a restaurant in la. itsjob — yep, you've guessed it, is flipping burgers. it uses image recognition and heat sensing to cook. the company, caliburger, is installing flippy in 50 locations but it's not cheap at $60,000 a robot. hope those burgers taste good! i think you found him. that's not possible. if this gets out... we've bought ourselves a war. there's obviously a huge responsibility to deliver something for the audience of blade runner from the first one. the expectation visually, making everything look cool, was on our mind every day. the demands of vegas and the expectation of making something that was based on what we know vegas now, but what it would be in the future. so we started with the us geodata, the vegas valley and the city itself. so we had a simple model in the computer. dennis gassner, the art

director of the film, had built a simple model of vegas with some new buildings placed around and so forth, we took those two and sort of smashed them together initially. we looked for ways very subtly of how to bring in the human element into the shots, how to sell that scale, analysing some of syd's work and how he used graphics on the face of his buildings, how he in a lot of his paintings used little human scale futuristic items. we built all that stuff and placed it around the city in an organised way to make it look like people were there at one time, even though we see no one, and that's what made it look real or look like a place people could have been in. to build trash mesa was based on the idea that everyone had moved to the city and all the structures are outside the city had been pretty much abandoned. there was no power, no water, nothing outside, so the trash generated from the city was dumped on the buildings outside the city. again, we're trying to base things on as much reality as we could,

so we started with the landscape of current day california, from los angeles to san diego, and we determined iceland was the place to photograph the groundscape and the beach. the sequence of the ships was based on the bangladesh ship harvesting yard where they recapture all the metal and so forth that happens now. so a lot of the ships and the pieces of the ships and the idea of these little tiny human beings working on these massive structures sort of drove that look through the middle of that sequence. so it's a matter of grabbing all these components that were based on today's reality, scaling them so they have this massive relationship between k in his little spinner in this enormous landscape and these huge mounds of trash. it was just a matter of pulling off that scale and that distance, which was just a massive undertaking just with the amount of data and assets we had to build and things we had to manage in itself to pull that off. the future of the species is finally unearthed. it is a brilliant film, absolutely superb. blade runner 2049, a well—deserved oscar winner there.

that's it from us for this week. don't forget, the full—length version is ready and waiting for you to watch right now on i player. and we are always waiting to you on twitter and on facebook as well. thanks for watching, and we'll see you soon. hello and welcome to newswatch, with me, samira ahmed. the attempted murder of a double agent on british soil, did bbc news report it proportionately and fairly? and was the oscars ceremony an excuse for trivial gushing over celebrities, or a welcome dose of glamour? the week began with some news that could have come from a john le carre novel, described here at the top of monday's news at ten by fiona bruce. a former russian spy is critical in hospital after a suspected poisoning in salisbury.

sergei skripal, convicted of spying on russia for the uk, has been living in britain for nearly eight years. police in protective clothing have sealed the area after the russian and a young woman were found unconscious on a bench. we'll bring you the latest, as police and doctors race to establish if this is another example of a russian being poisoned on uk soil. that last suggestion of russian involvement was examined many times during the week, but without any conclusive proof being put forward, and that prompted one twitter user to complain that... evidence of russian involvement wasn't the only thing lacking. despite plenty of airtime being devoted to the story, actual news developments were slow to emerge. a viewer called john e—mailed. .. meanwhile, mike barnes had a different point to make.

if some thought there should be a presumption of innocence for russia over the nerve agent attack, then for others, the same was true of bradley wiggins. the olympic gold—medal—winning cyclist was found by a house of commons select committee on monday to have crossed an ethical
