this is bbc news, our latest headlines: dame tessa jowell has died at the age of 70, she was diagnosed with a brain tumour in may last year. dame tessa was first elected as an mp in 1992 and went on to serve as culture secretary for labour, she played a major role in the 2012 london olympics. former prime minister tony blair and labour mp harriet harman are among those who've paid tribute today. she did everything with the same passion, determination, birth ability and charm, so she was a unique politician but she was a really dearfriend. unique politician but she was a really dear friend. she did her politics in a different style, by befriending people. she befriended the powerless because she wanted to support them and she befriended the powerful because she wanted them to defend the powerless. one person has been killed and four wounded in a suspected terror attack in paris.

the suspect, who was carrying a knife, was shot dead by police. indonesian police say a mother and father and their children carried out the three church bombings that killed at least eleven people. israel have won the eurovision song contest. singer netta lifted the trophy at last night's final in lisbon. now on bbc news, click. replica art, replica popstar and a robot that we wish could replicate doing the laundry. the future starts here.

more specifically at london's victoria and albert museum. i have come to an exhibition that hopes to make us think about how we want to live our lives in the future. there are over 100 items on display, a lot of them we have seen on the show before but here they are presented in a different light, in a somewhat unsettling one. here is an immersive dome. a reminder of how our lifestyles are poisoning the earth. it's not every day you an artificially intelligent sandpit and it really is quite compelling to play with. so there's some more water. the creators have extracted topography data from thousands of satellite images and fed that into a neural network to create this interactive display. as i dig deeper, the land level drops and it turns to sea, or if i pile up the sand,

it transforms into green mountains. this is a future that i could enjoy, a bot that is doing the laundry. admittedly, brett here is a little bit slow. it currently takes ten minutes to fold the towel but that shows just how difficult it is to teach a robot mundanejobs and in fact he does learn through trial and error so the more he keeps doing that, the quicker this is going to become. that may take brett some time. meanwhile, elsewhere in the v&a museum they are facing a challenge almost as complex. there are more than 2 million works of art here, the largest collection of decorative art and design anywhere in the world and, as with any museum, they want to check that hiding amongst them aren't any fakes orforgeries. telling an original from the real deal is not simple but, as geoff white found out

in prague, technology is making the process easier. a roomful of reubens at prague's national gallery. even the untrained eye can tell the work of a master but it's not always easy. recent forgery scandals have got the art world in a spin. the question is, up close and personal, could you spot the impostor? the national gallery up there has a team of people whose job it is to make sure the works on display are the real deal. all the big art institutions do, but it doesn't always work. some of the world's greatest galleries have been caught out by the forgers. can technology help? here in prague, they are using space industry tech to see if it can spot a fake. this prague start—up has got a challenge for you — which ones are the fakes? this, for example, looks

like an edvard munch. if so, conservatorjiri is handling millions of pounds. the truth will be revealed when it goes in the scanner. on this side, we have an x—ray tube which emits x—rays. it's not emitting? it's switched off. but on the other side, supersensitive detectors first developed at cern, the world's largest particle physics lab. it's a new generation of x—ray imaging detectors which allow also measuring wavelengths of x—rays, so in way we can create colour x—ray images. those colours reveal layers and even ingredients of paint, sometimes ingredients way too modern for the alleged artist. we can also distinguish different materials which may or may not be from the period the painting is supposed to be from. and with robotic arms, they are hoping to scan

more than just paintings. sculptures, pottery, even entire pieces of furniture. what about that edvard munch? after a few hours scanning, the moment of truth. the x—rays have revealed a hidden secret. hang on, do you see... what do you see? that is a vase of flowers, isn't it? munch rarely did flowers and the scans show titanium in the paint. munch didn't use that. so whoever has got this, hasn't got an edvard munch on their hands. have you told him, does he know? yeah. butjiri thinks he has found a genuine work and it is potentially a very, very big deal. this looks like a vincent van gogh landscape. it's from a private collection. you are seeing it for first time. and the scan revealed a vital piece of hidden evidence. there is the head, the shoulders,

the hands and legs here. it's an unfinished female nude of exactly the type van gogh painted. the artist was so poor, he frequently reused canvasses. jiri thinks it's the real deal, and it is a big moment. it was crazy feeling. when i seen it, i can't believe it. because in your life, as a restorator, it is a really special moment. the scans, along with years worth of other evidence, will be sent to the vincent van gogh foundation. if they decide it is real, it would be only one of two full—sized van gogh paintings discovered in the last 80 years. the last one sold for almost £40 million. insight art scanning is just one of a battery of high—tech methods now authenticating art. mobile apps can be used to track

pictures around the world. artificial intelligence can be used to compare individual brush strokes. high frequency scanning can reveal minute imperfections. all in an effort to keep ahead of the forgers. speaking of whom, welcome to david henty‘s house. there is a walter sickert in the spare room. a caravaggio at the end of the bed. oh, and a francis bacon. and out on the balcony... let's look what you've got out here. wow. several paintings here. but none of these are actually real? they are all fake? again, depends who's asking! there is only probablyi or 2% in the world that can afford a $100 million picasso so if you want a picasso, the way i look at it, this is the nearest you are going to get to it, is a david henty picasso. before he was exposed by a national newspaper, david sold his forgeries but carefully stopped short

of claiming they were definitely the real deal. when i was forging, i've seen my paintings at the art auction catalogues. i wouldn't like to say which ones because it'd get someone into trouble. not me, because i sold them legally. now he has gone straight, his buyers know they are getting a forgery, albeit a lovingly crafted one. and anti—forgery tech is all part of the fun for fakers. as soon as you come up with a bit of technology, we are looking at a way to get around it, which is what a good forger will do. according to one former fbi art investigator, the forgery market is worth up to $6 billion. and with skills like david's on display, the art world might want to turn to the latest tech before signing off on that multimillion—pound deal. that was geoff.

meanwhile, with a new collection of david bowie prints about to go on sale, we sentjen to find out how technology is being used to make sure they too are the real deal. many people have of course followed his flamboyant style over the years, and it is still widely imitated today, but how do you separate the imposters from the original? # let's dance. # put on your red shoes... in 1983, david bowie took off on his hugely successful global tour, serious moonlight. promoting his album let's dance, the world saw a different side to the musician. about two days ago, emi records phoned me up in australia and said, would i like to take a 25—hour flight back, and come and sit in a room with 75 journalists? this is 35 years ago, and at that point, no—one had ever really seen david like that. he had this ice—cool image of ziggy stardust, was pretty defined, then you had low, et cetera, he was this ice—cool figure and then let's dance came

along and he became more human. before he died in 2016, david was working on a project to commemorate the tour and incorporate many unseen photographs shot by denis o'regan into a coffeetable book. this is when we left someone's house and we went to the car and david did this for no apparent reason. he will drive the non—existent car — very david bowie. now dennis has expanded the project, ricocheting into five books being sold with three rare photographic prints. he selected the photos, including many candid snaps, from his own collection. these contact sheets from the time, david has squiggled on a few of them. oh, lovely. it's quite odd, really. i love that. if david was looking at these now, he would say, i love that.

but these days, we can take thousands of photographs, whenever we want to, on our phones. so what makes these prints rare and worth collecting? all of these shots were taken on film so, by definition, you couldn't take 1,000 pictures an hour. you would take pictures as and when you thought you had a good photograph. we only do... sometimes it's only 25 prints of that image and there will never be any more printed from that image. but how do you make sure you've got an original print from dennis and not a fake? ricochet is being secured by a company called techsmart. they're using synthetic dna in the uk laboratory to help authenticate the prints. this material is incorporated into a stamp with david's initials. it's divided into several areas with different inks, each ink has a different

security element inside it. this invisible one is fluorescent, under uv light. the process of what goes into the stamp is so secret that only two people in the company know exactly what materials are used. we use different inks and we use also use different inorganic compounds. some of them are rare earths, different types of element we use. and sometimes we use very traditional ones, but we use them in unusual ways. this specially developed scanner can detect the unique materials but sometimes the security features are invisible, like on the certificate of authenticity. but we are assured they are there. i thought this was more forwardthinking and innovative. and it's something not particularly visible on the prints so it's is not as hackable in this day and age. hopefully completely unhackable. along with the books and photographs, a 12—inch

picture disc of ricochet and let's dance remastered by nile rodgers will be in the set, selling for £3,000. how do you think david bowie would have reacted to this? well, i would like to think that, as he was the most extraordinary innovator and unbelievably original, i think he would have been quite tickled by it, i think. hello, and welcome to the week in tech. it was the week that the researchers at the university of toronto showed off a hand—held 3—d skin printer that can apply layers of skin tissue directly on to patients to cover and heal wounds. google announced it would ban all advertisements relating to the republic of ireland's forthcoming referendum on abortion. and california has become the first american state to require solar panels on almost all new homes. the ruling is not due to come into force until 2020 but has faced criticism from those who believe it

may increase house prices in the short to medium term. and if you are sick and tired of your autonomous car not being able to drive you to the right place, because the area around has not been properly mapped, mit have unveiled a system using gps maps and laser sensors, maplight, to allow an autonomous vehicle to drive in rural and previously unmapped areas. and finally, talking of rural areas, the scenery around the lake district may be so beautiful, it's earned it unesco world heritage status but its roads aren't so pretty and are often clogged with wayward walkers. one solution sought by the lake district national park is self—driving pods which could ferry tourists around the picturesque landscape. a feasibility study has been launched but doubts have been raised about the pod's ability on the area's notoriously bumpy roads. at this year's google's i/o developers conference,

the chief executive wants people to think aboutjomo — that's the joy of missing out — and unhooking ourselves from our tech addictions. jomo — the actual joy of missing out. we think we really help users with digital well—being. this is going to be a deep, ongoing effort across all our products and platforms, and we need all your help. this is all part of a trend of technology companies becoming increasingly worried that their products are making us miserable. facebook has talked lately about time well spent rather than just idle scrolling through your newsfeed. but google, of course, has the android mobile operating system — the most popular in the world — so it can do a lot to solve this problem. the software will prompt you to take a break if you have disappeared down a youtube binge watch hole for too long. if you are the kind of person who lies awake reading your phone at night — and that's all of us — the wind down mode would

automatically set your phone to do not disturb and make it greyscale — something usability experts say will make you less tempted to use your device for as long. and you can set limits to certain apps. when you get hit that limit, the app will be greyed out for the rest of the day. and if you want to show someone that they have your full attention, google has introduced shush mode. you simply take your phone and place it face down on the table, and it will automatically go into do not disturb. but are features like this going to be enough to solve this huge problem? google's assistant will now understand detailed follow—up questions, removing the need to say "hey, google" each time you have a command. when‘s the next game? the warriors' next game is today at 7:30... google maps will help direct you the next time you're stuck on a street corner by using the camera, so you can find out which direction you are facing. and perhaps most impressive of all was this. the voice on the left isn't human.

it's google duplex — advanced ai that is able to interact with a real human being. it can book things like hair appointments or tables at restaurants. google wouldn't let us test this for ourselves so i can't tell you if it really works or not, but if it does, wow! that was dave. back at the v&a, i'm exploring some of the other exhibits. the ability to study our dna has the potential to cure diseases. bento lab is a dna lab in a box which could make biohackers of us all. we borrow a lot of ideas from how, you know, raspberry pi teaches people how to learn computer coding and all these other great bits. i think we like to think of it as a duolingo for learning genetics, just how you might learn a new language. i am really excited about the future of biotech when more

different types of people, you know, 16—year—olds to 65—year—olds can be a part of it, having lots of different voices being enabled to go into biotech through this is really exciting. next week is mental health awareness week in the uk. but, of course, the problems it is highlighting are of international relevance. and as mental health continues to grab the headlines, we have sent paul carter to take a look at some of the latest digital tools that aim to help. when i first started to self—harm and i started to cut myself and it was just a release and it was like i was in control of something and, like, it was, like, i was matching the pain on the inside as well as on the outside. there is still a lot of stigma around mental health and people feeling like they have got to be ok and they've got to get on with it. i've struggled from anxiety for quite a few years, since i was a small child,

because of issues that i faced at school. if you address that now at school level at the younger years, then hopefully that will build a generation of people who are open to talk about mental health. and that conversation around mental health could indeed be aided by technology. often seen as the bogeyman that's harming children and young people, there's a suggestion that technology could now actually pose solutions to those very problems. it's estimated that one in four adults experience mental health issues each year in the uk, and that 75% of mental illnesses start before a child reaches their 18th birthday. treatment, though, can be slow. at present, only 20% of children and young people who have significant mental health problems that would benefit from intervention are actually receiving the sort of standard services that we recognise. we really need to think about how we can reach that additional 80%. some of that needs to come

through a greater expansion of conventional mental health services but i think we also need to look to new technology to help us. one group of young people who might face particular challenges around mental health are students. here at the university of the west of england in bristol, they've partnered with a platform called kooth to provide an online, anonymous counselling and well—being service for the young people who study here. it offers online forums, self—help materials and tools and live one—to—one counselling sessions. one student, who wanted to remain anonymous, has found the pilot very helpful. i struggled with low mood and anxiety and self—harming in the past and that was still going on when i started university, and i wasn't really sure how i could really build any therapeutic relationship with someone who i'd never met. but it surprised me

that i actually have. being able to write it down is a lot easier, because sometimes i find it difficult to say what i am feeling and ifind it easier to put it into words. another great plus of online services is the peer—to—peer support available. there are many tools and platforms out there to try and help young people at an early stage, and the anonymity of online is often a big plus. these students found using a bot app a great help. although users can go to online counsellors, 99% of wysa usage is via an ai chatbot that's overseen by clinical psychologists and which uses natural language processing to drive the conversation. there are also mindfulness exercises and interactivejournals, which help build emotional resilience. a lot of people feel like if they are talking to a person, then this is, like, it's a major problem, where if it's a bot, they can just talk and talk and talk and it doesn't have too much of an effect. you still get the sort of support that has been put in place by people

who are professionals, but you don't still feel like you are sat there being judged by someone who is listening to what you're saying. it has meant that i can just go along day by day, having those little moments just to myself where i can go to wysa and just have that little bit of downtime. because of the stress that i have been feeling recently, i have suffered from a couple of panic attacks at times where i have not really known what to do so using various videos and techniques on the app has helped me to relax and beat the anxieties that i am feeling. begin byjust noticing your breath. 17—year—old courtney from greater manchester started having problems after her parents split up. she found the moderated chats and other guidance tools through the big white wall a great help. i was really scared at first. like, i didn't want other people

to know and i didn't know what was going to happen and i thought i'd be judged because of it, but i'm glad that i did reach out. group talkabouts with, like, several people are in it, or you can have a personal one with just you and another person. you can have conversations with other people about, like, things that they have gone through and you can find out their experiences. it is just something that allows people to get the help that they need as soon as they need it, instead of having to sit and wait. without that, i know that iwould be, like, really, really stressed and struggling to cope with the pending exams. stopped my self—harming. they've given me, like, different techniques. digital technology has the potential to be hugely beneficial in reaching children and young people with milder conditions who can take up the benefits of self—management and particularly at an early point in their experience of a mental health problem. we all know that the nhs isn't as giving as it would like to be,

which means that young people could suffer without technology like this. well, that's it from the future starts here. spencer will be back next week. but in the meantime, you can find out what we have been up to on facebook and twitter at @bbclick. but for now, thank you for watching. part two of the weekend is certainly looking better for most of us than part one. eastern areas looking dry, some sunshine around with glorious spells and sunshine to begin the day further west and across wales.

through the afternoon rain across northern areas, particularly for the far north of england, scotland and wales will clear away. then most places will be dry. this weather front is the culprit. that will continue to move northwards and clear away from the east coast, so a bit more cloud around eastern areas. some mist, but the rain across the mainland of scotland will become confined to the northern isles later on. much of england and wales fine and dry with sunny spells and some sunshine in northern ireland. temperatures reaching highs of 16 or 18, it will feel pleasant in that strong may sunshine. the rain becomes confined to shetland, lingering a bit overnight, this weather front returns again to eastern coastal areas by the end of the night, could bring the odd shower, some cloud for the western side of northern ireland, otherwise a clear, dry and chilly night.

into monday, high—pressure building, that will keep those weather systems at bay. looking fine and dry for most of us on monday, that weather front will continue to bring some cloud and showers to east anglia and the south—east. as it moves west it will fizzle out, becoming a band of cloud. cloud pushing into the north west of scotland and western parts of northern ireland, maybe the odd shower but for most of scotland, england and wales, a lovely day with lots of sunshine and warm, top temperatures of 21. tuesday looks even better, we lose the cloud and showers. this weather front pushes into the west of scotland and northern ireland, some rain on it, cooler air as well, only ten or 11 degrees the stornoway. but ahead a lovely warm day, temperatures potentially 22 or 23. it stays fine for much of this upcoming week all thanks to high pressure, wind is light and

plenty of sunshine. it will start warm and cool down a little bit midweek onwards. good afternoon. the former labour cabinet minister tessa jowell, who campaigned to raise awareness of brain cancer following her diagnosis a year ago, has died. she was 70. a leading light in tony blair's government, tessa jowell was also instrumental in bringing the olympics to london in 2012. this morning mr blair praised her courage and dignity in publicly confronting her cancer, saying her efforts to raise awareness were a lasting tribute to a lifetime of public service. leila nathoo looks back at her life. the games of the 30th olympiad in 2012 are awarded to the city of london.
