in a threatened congressional before they were both found collapsed seat. kim jong—un. on a bench. from washington, chris buckler reports. those were the latest headlines. now on bbc news, it's time for click. proud to be an american where at least i know i'm free. least i know i'm free. the app that helps record and report sexual assault. the ai going after cancer. and the man who wants us all to live forever.

in bringing about true gender equality in all walks of life. as we'll hear later. raises a lot of questions. but tech can also be a force for good. to expose just how widespread sexual harassment and assault is. a little bit easier. survivors of sexual abuse, and the creators of callisto. every tattoo tells a

story. the story is bittersweet. with lady gaga during the 2016 oscars. and to give us strength. and to know that you're alone. which investigate sexual misconduct. and later, i did find out that he had done a lot of... and also assaulting someone else. what was that

experience like? it was awful. back and forth every single hour, every single day. wants greater transparency in the adjudication process. happen on their campus, because that makes your university look safer. it's better for your public relations. and has begun reporting case numbers. while in college. i was sexually assaulted by a friend. than the event itself.

were there to protect me was incredibly destabilising. so survivors would have a way of reporting sexual assault. if they don't want to. two, report electronically to the authorities at their school. the same assailant. as an 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? but also a series of unique identifiers. currently, facebook profiles are used to match.

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. there is definitely an increase of reporting. to write about the incident. gives people power. shanta katipamula led an effort to bring it to stanford. when no—one‘s staffing. at the own pace, privately.

and tell a wonderful story arc. and that's particularly not how memory works in the event of trauma. isn't later used against them. that can't be recovered. not quite a one—click sign—up. that deters some users. for callisto, it ensures privacy. and we want to make sure that even we can't view what's in the form. some records are never seen by schools. but they're still useful.

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. report electronically. though she see its potential. what i think callisto is great for is to track perpetrators. in and have a very powerful effect. to track any perpetrator, even as they move through space and time. something ladd says she wonders to this day. that was sumi

das at stanford university. that is rare. even right here in silicon valley. of san francisco, where all colours and genders seem welcome. have been mainly men. of sexism and masculine culture as anywhere else. it's the social challenge where the majority of people... and the host of bloomberg technology. that has always self—selected for men.

of the cocky, self—confident risk taker, the ‘bro'. in the world, and that is the technology industry. how we shop, how we communicate, how we get around. from this incredible and progressive industry was not inevitable. it didn't have to be this way. but never got a chance because they didn't look the part. and that is something that needs to change. women hold just 25% ofjobs across the computing industry. they account for 7% of investors. women—led companies get just 2% of venture capital funding.

silicon valley has become toxic for women. so what is bro culture? fratty parties, beer, behaviour that is alienating towards women. of the day, there was a heavy drinking culture. and they're stuck in sort of an impossible catch—22. if they attend, they're disrespected and discredited. are at these parties.

about how an investor has crossed a line. that i found is that an investor who... who often hosted hot tub parties at his home. while wearing a bikini and drinking beer? field in silicon valley. at the creation of some of these companies from the start. would online harassment and trolling be such a problem? and he said he doesn't think so. they weren't thinking about that when they were building twitter.

it can be used to send death threats or rape threats. is one of the biggest problems plaguing internet today. maybe online harassment and trolling wouldn't be such a problem. if they can do all that, they can change this too. hello, and welcome to the week in tech. from being released on the playstation 4. it's been criticised as too sleazy and for promoting toxic behaviour.

they'll be developing their cordless battery range. 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. under investigation over the way they handle data on their network. internet speeds while customers are abroad. without the museum's permission. the project was called hello, we're from the internet.

has begun working at a restaurant in la. itsjob — yep, you've guessed it — flipping burgers. it uses image recognition and heat sensing to cook. but it's not cheap at $60,000 a robot. hope those burgers taste good. height, weight, sex and even our genetic make—up. biomedical data to be beneficial, though. what i have here is the beta version of the exactcure app.

because that could have an affect. about to take. and this is how you do it. so this is paracetamol. that would be likely to have. maybe doesn't need to be taking to tablets in one go. fully red. you have, and of course genetics.

million people, and this data could soon be at your gp‘s fingertips. local gp, and have that genotype already available. medicine for you. the doctor's already got your dna. being specific to your needs. want to face.

diseases, they're actually trying to lengthen the human lifespan. ageing itself as a disease which can be cured. and he's made some seemingly rather outlandish claims in the past. already been born? i always make clear that it's only something i think is probable. but yes, i do think it's probable. the risk of dying in your 20s is low. of reaching your 27th birthday is very high. the chance of not reaching it is less than

one in 1,000. in the coming year goes up. it happens to go up by about 10% per year. does it, 10% per year? than you are at the age of exactly 62 and so on. blimey, that's quite high. have to do with how long ago you were born. cancel out ageing? the damage the body does to itself throughout life. this is something i've called longevity escape velocity.

we're talking about massively lengthening people's healthy lives. there would be approval from society. had massively extended lifespans? what society's going to be like. what gets me out of bed is the fact i don't like people getting sick. i don't like the fact 100,000 people a day die of ageing. i'd like to hasten the defeat of that problem. one year per year. to figure out what to do about it. the enigmatic aubrey de grey. to be more than 1,000? that would be strange, wouldn't it?

is a pretty bleak time. behind—the—scenes science that went into making that world. i think you found him. that's not possible. if this gets out... we've bought ourselves a war. for the audience of blade runner from the first one. was on our mind every day. but what it would be in the future. and the city itself. so we had a simple model in the computer.

and sort of smashed them together initially. of his paintings used little human scale futuristic items. or look like a place people could have been in. pretty much abandoned. generated for the city was dumped on the buildings outside the city.

was the place to photograph the groundscape and the beach. all the metal and so forth that happens now. of that sequence. amounts of trash.

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 we live on twitter @bbcclick and on facebook too. thank you very much for watching and we will see you soon.
