Officials in oklahoma dig up 1a bodies for a second time, in the hope of using dna to identify more victims in 1921 the tulsa race massacre. Now on bbc news, its time for click. This week, shiona has been to sweden to see how new organs could be printed in a lab. Meanwhile, lara has been creating body parts of a different kind. Whats happened to my ear . Nick talks to a man in a box. And the man hunting the missing cryptoqueen explains how to find someone from a single selfie. Even if i posted a picture of me in my back garden, there is a possibility someone could work out my home address, because ive done it to them. Nearly 7,000 people in the uk right now need organ transplants. Sometimes the wait for these lifelines can be long and agonising. And not everyone survives them. We clearly need more donors. But 3 d printing might be able to offer a solution. Yeah, scientists are developing a method to create organs from living tissue, which can then be transplanted into patients who need them. And Shiona Mccallum has been to gothenburg, in sweden, to find out more. Its been more than 70 years since the First Successful organ transplant, a kidney. The chances of further operations of this kind being conducted. People who want to donate their organs can have their names put on a computer by using, for example, a new type of driving licence application form. And thanks to the donor register, hearts, lungs and livers are now among the 100,000 organs replaced every year. When you lose someone and theyve given that gift, that huge gift, you are immensely proud of them. But even now, it remains a difficult wait for patients. It tookjust over a yearfor me to get my transplant, and i deteriorated a lot during that time, and i was constantly in and out of hospital, getting weaker and weaker, so yes, it was a terrible and terrifying time. Here in gothenburg, one team are trying to solve this, and theyre using technology thats a bit like a 3 d printer. Theiraim . Well, its to grow organs from cells, here in this lab. No donor necessary. Today we are going to look at printing skin. The skin is composed of different layers. 0k. And every layer has different types of cells and combination. It is the human bodys largest organ but even a small skin model requires millions of cells. Theyre mixed into different bio inks for the machine to choose between. You really design a code, what tells the printer what to print, when, and in which structure. Its a lot more visible than i expected with the naked eye. A hollow Blood Vessel Structure has been layered inside this one, and a syringe like printhead has a different purpose. So you can actually print cells for Hair Follicles to really replicate the skin. At this stage it kind of looks like a bit of toothpaste, but actually, its seriously complicated cells in here. While 3 d printed skin could be applied in surgical grafts, drug and cosmetics testing, the cells have to mature first. This is where we culture the samples weve printed. Theyre kept in incubators for several weeks, and this tray is about a week old. The tough part, which is mimicking the top of our skin, is on top. A mix of proteins and Nutrient Molecules is fed in and the waste is removed. All while being closely monitored. The beauty with this microscope is you can actually watch your sample through an ipad, so its no longer looking through those small eye things. Green dots for living cells, red for dead. So theres not that many dead cells here which you can see. Which is a very good sign. Close analysis of the end results is needed to finetune. Cellink has been printing cancer tumours, so that patients could receive personalised treatments without enduring drug trials themselves. Theyve also made liver models for Drug Screening campaigns, and are helping Beauty Brands become Animal Cruelty free, thanks to testing on lab grown skin. In this gothenburg hospital, researchers plan to put such bio printed cartilage in patients with muscle issues in just a few years. First patients is of course the sports injuries, because they will probably heal better, at least we think so, but also for elderly patients or patients that suffer from osteoarthritis. We get very nice Cartilage Tissue that have healing capacities, so we are very optimistic. Further studies are needed to prove the methods are safe, but it could save time and money. We can actually print what the damage looked like before. We can actually print directly into the knee, probably, in the future. We can mass produce it, i mean, we can start with a printer and then go home and make thousands of copies. And more complex procedures are coming down the line. What do you feel is the ultimate aim . Many people die waiting in the line for organ transplantation, so what we are hoping is that this technology in the future will actually be able to provide these organs. How far off are we . I think 15, 20 years is when we might see it in clinic. Simpler organs can be seen very, very soon. But if were talking a full organ, internal organ, that will take some time. One of my oldest friends is alive, thanks to a donor liver. To not have that over a year wait, to know that they would be potentially growing and organ for me, if thats all it took, i would have been in a stronger place to have the operation in the first place. It stops a loss of the worry, i would imagine, because you know its there. Unlike this waiting game that you dont know when its your turn. Would you feel differently about having an organ that didnt mean that someone had to die . Youre waiting for somebody to die and youre waiting for that person to be in the right blood group, the right size. You know, i couldnt have a 68, massively obese gentleman, because it wouldnt have fitted in my abdomen, so if youre able to eradicate all of that and then almost home grow your own to the exact perfect fit, yes, i think it would be life changing for thousands of people. There is a way to go yet, but the first steps from skin cells to mending muscles are promising. I wont be the only one hoping lab grown organs could cut the queue to life saving operations. Over the years, video calls have got better and better. Recently, theyve got so lifelike, its ridiculous. Its ridiculous. Do you remember portl . This is you in a box . Yeah, thats me in a box. This is an la based start up that was building, to be honest, the closest thing to holograms that i think ive seen. Theyve since renamed themselves proto, and now theyve come up with something that promises to take up a little less space in your living room. And nick kwek� s got an early peek. Its crossed contintents to be here, and today its making its all singing, all dancing, star studded debut. And my honest reaction . Utterly gobsmacked. This is weird, isnt it . To the proto team, happy cinco de mayo. Viewing the tabletop sized box is like watching a 3 d movie, without the glasses, but with shrunken characters and objects appearing like theyre physically inside. Well, hello there oh, hi when spencer interviewed me, i showed him the non working prototype. It was only a vision, but here i am, beaming into an actual working device. I cant believe im actually speaking to you now, live, in la im actually not a hologram, im really in this thing let me out we wanted to go from the boardroom and the Conference Room into the living room. You shouldnt have to be a millionaire or a celebrity, or even a digital resurrection of a late legend. This should be so grandpa and timmy can communicate, whether theyre ten miles away or 10,000 miles away. Looking a lot smaller than i recall. When a volumetric, real sized person, even shrunk down into a tabletop sized version of a person, materialises into a space, there isjust a much more emotional Connection Thatjust does not exist when you are just chest up on a flat, 2 d display. This is sort of like if zoom and being there had a baby. Its the real empty space within the box, the shadows on the inside walls, and the reflections that create the illusion of physical presence. 0h, paris hilton i am so excited and proud to be a part of this im looking at paris� eyes, and shes looking back into mine. And wherever i am, looking around the device, were maintaining eye contact. A trick, thanks to the boxs depth. What about that physical connection that you have with people when you meet them for the first time, orfor a Business Meeting . People are no longer getting on an aeroplane and travelling from city to city to city, and spreading jet fuel all over the earth. As were well aware, video calls can be temperamental, with even the slightest of delays putting us off. But this is fairly slick, even whilst hotspotting over 4g on my phone. Weve gotten the transmission to around 200 milliseconds. Which, perceptively, is instantaneous to anybody interacting. Many holographic devices, as you see in the acquisition, is super complicated. It requires multiple cameras, multiple angles, a chromakey device. We are able to achieve a holographic transmission with one camera. Today, david is being captured in his professional studio, but theyre working on an app so people can record themselves from their smartphones, and eventually they want the m to do the recording itself. Its front facing camera could be very smart, indeed. We have technology thats being deployed very soon to do automatic demographic and age recognition, so we can even understand if you are male, female, your age range, and serve your content to that effect. It will cost around two grand when it hits the mass market as early as next month, but proto is already working with big brands to help them flog stuff, and is also entering the health and education sectors. Theyre using it so doctors can beam in and train future Healthcare Providers how to treat and diagnose people. Theyre teaching students in multiple universities at the exact same time david, thank you so much forjoining me. All right, beam you later this that was nick, and now its time to look at this weeks tech news. The uks Competition And Markets Authority has again ordered meta to sell giphy. They found that owning it could harm competition. This is the first time the uk has blocked a takeover by a tech giant. Kanye west, or ye to his friends, has agreed to buy the so called un cancellable social media platform, parler. His anti semitic posts meant his twitter and instagram accounts were restricted. So far, little has been revealed about the deal. Ye will say that he is a proponent of free speech and that he will be buying this website to promote that. Parler has, what, about a million users, reportedly. Twitter has got 238 million. Looking at it from a financial analysts point of view, twitter doesnt charge for its services, it doesnt make any money, so it will be interesting to see what he thinks he can do with it and what benefit he could derive beyond, perhaps, his championing of what he would call free speech. Chiles government has deployed its first ai listening smart buoy. 600 miles off the coast, the buoy monitors oxygen and temperature levels in the ocean, as well as alerting ships about nearby whales. Finally, fedex is saying goodbye to its robot delivery programme, roxo. Fedexs Chief Transformation Officer said its no longer meeting customer needs, and this follows the news that amazon is also scaling down its own last Mile Delivery robots. In 2018, the click team went undercover to investigate a scam. People were being promised huge profits if they invested in an apparently new cryptocurrency called 0necoin and then talked their friends and family into doing the same. The problem was, 0necoin didnt exist. A few months later, journalist Jamie Bartlett started investigating a mysterious twist in this tale. 0necoin� s wealthy and charismatic co founder and figurehead, dr Ruja Ignatova, regularly seen on stage at lavish events promoting 0necoin� s supposed promise, had vanished and jamie wanted to track her down. For eight weeks, jamie fronted one of the bbc� s most successful podcasts, as he reported on his hunt for the missing cryptoqueen in almost real time. What a house. 0h, theres a Security Guard there. We are looking for the house of dr Ruja Ignatova . Its this one. 0k, do you know where she is . No idea. Doesnt know where she is. He spoke to people ruja had known, saw the spoils of her wealth, and followed leads from listeners around the world to try and find someone who had persuaded so many people to invest in a Get Rich Quick Scheme of astronomical proportions. It was the perfect scam at the perfect time. The hype of bitcoin, the lack of regulation, the price of bitcoin through the roof. The pitch was, 0necoin Is Bitcoin but better. 0necoin Is Bitcoin but cheaper. And if you want to make, not 5 a year, not 10 , 1,000 a year, youve probably missed that with bitcoin. Jamie has been able to piece together most of the 0necoin story which he has turned into a book. But even now there are new developments, which means more episodes of the podcast as well. Dr Ruja Ignatova has just been added to the fbis top ten most wanted fugitives list, making her now one of the most wanted women in the world. Is that thanks to you . Laughs. Be careful how you answer. Im not sure, but the way i see that media works sometimes is that if you can create a lot of excitement and interest in a story, suddenly the authorities decide theyre going to act. I think what is interesting about her appearing on that list is she is the first ever crypto scammer, so alongside cartel bosses, alleged murderers, now we have a crypto scammer. How difficult do you think it is to disappear completely these days . I had always assumed almost impossible. Except that. If you have got enough money then you can change your appearance somewhat, you can fairly easily obtain fake identity documents, and as long as you have iron discipline, you dont make a mistake, you stay undercover or you are very well protected by governments that are happy to keep you there, i think you can disappear. But not only do you need discipline, your Close Friends and family need to watch their Digital Footprints too. We were trying to find this hidden mansion we had heard rumours about in dubai, that we believed ruja had purchased no one knew where it was. We scoured through her brothers instagram and found he had taken a selfie six months after ruja had disappeared, which he had tagged as being in sofia, bulgaria. But the background looked like it was somewhere in the middle east. And there were a few buildings in the background, so you know, there were a few little clues, that we brought in a couple of open Source Intelligence specialists who are experts in being able to take a photograph and track down the precise location it was taken. So this one guy does a lot of reverse image searches for all the buildings in the background, and he has found the video of the exact buildings in the same order as in the selfie. So he thinks, great, i can now tell you that it is in dubai. Where in dubai . Well, now i will use google satellite to start trying to look down at where those buildings are, and try and work out a line of sight using sort of basic geometry, really, to try and pinpoint down to the exact location. And he starts matching up trees, pylons, small buildings, walls he can see on google satellite, that match the background of the instagram selfie. All the way until he is able to identify little patches of stains on walls, and then finds the house using google satellite that matches the picture, and basically sends us an address and says, this is where the photo was taken, in the back garden of that property on that street, and ijust couldnt believe it, from one instagram picture, that is how much a specialist can find. And in the book, you say you havent posted much online yourself since . There is a reason for that, because i know the people involved in 0necoin probably dont like me very much. And i realised, even if i posted a picture of me in my back garden, there is a possibility someone could work out my home address, because ive done it to them. Spencer talking to Jamie Bartlett there. Meanwhile, i have been me to meet a company hoping to create affordable, hollywood quality avatars with your mobile in minutes. Shrinking the hollywood sized setup and budget might make a booth like this possible anywhere whether it is to create a gaming avatar, in a Makeup Department for skin analysis, for influencers flogging stuff, or dare i say it, for the ever threatened metaverse. Lumirithmic� s setup here consists of a series of ipads, iphones and stands, so the cost of creating this is the price of those items. You could also use android devices. Once the images are all taken at the same time, they are stitched together to create a High Resolution picture. In a couple of seconds, i am scanned down to a tenth of a millimetre� s detail. An Imperial College spinout, experience and tech are brought together to initially perfect stills from all angles, recreating any lighting before moving on to producing video. I have been doing research on facial appearance capture for over 15 years in academia, first at the university of southern california, where i worked on hollywood scale scanning of actors� faces for movies such as avatar. Most Scanning Techniques only captures geometry and not the appearance. Here, because we focus on high quality appearance capture, the resolution comes from the reproduction of that appearance in a realistic manner in a 3 d rendering. Here we have the 2 d renders. This one looks like those images where you see the sun damage to your skin. Here, with controlled lighting conditions, we are analysing your skins reflections and breaking it into a constituent colour texture map, a shine map, a shape map, and which captures Yourfine Skin Pores and and wrinkle detail. Wrinkles, how dare you i know. Laughs. Youre a very brave man. And combining all of that with Computer Graphics rendering, i can now animate the light whichever way i like, and the skin will react. And in case you wondered, the weird rectangles in my eyes are the reflection of the ipads. 0nto the 3 d images now, which thankfully feel a bit kinder than the previous overly analytical close ups. And theres one striking feature. The lighting is quite something. And to think that thats virtual, because that really looks like we are moving throughout times of the day. The ability to create believable shadows is where the realism comes from. Even in an image that isnt itself animated, so getting this perfected should lead the way to better Video Versions down the line. Although, whats happened to my ear . But the holy grail is being able to do all of that with one of these. And the company has cracked it the pictures are lower resolution and they wont let me film the process, but i can show you the results. Theres still a huge amount of detail here, my hair goes a little bit funny as we change the lighting, but what is the actual difference in resolution . This resolution is about 2k and then the full desktop setup you have seen has a resolution of about ak, but the quality is still preserved and the fine skin details and also the geometry. The resolution is clearly good enough for most consumer applications. I dont think id want it to be any better. But. Definitely further work required in terms of work to be done in terms of cutting out smooth silhouettes. And what is most challenging there is not the body or the face but the human hair. The Hair Silhouettes are very fuzzy and not discrete, and so this is where better algorithms will have to be created. Even hollywood has the same issue, but it does have people for that. The Scanning Process usually does a pretty similar job that we are doing. It is the hair will then be modelled back to most of the Hollywood Rendering Systems using artistic Modelling Processes for hair. So hair is its own Research Problem in some sense. So these avatars may not be perfect yet, but they do seem to be heading in the right direction. How long do you think it will be before theyve got a fully working virtual version of us too . How do you know they havent already . Er, thanks for watching, we will see you soon. Hello, there. 0utdoor events, like halloween and bonfire night, just around the corner, and if youre thinking about grabbing the scarf and gloves, think again. Its going to stay very mild indeed. These are temperatures that we should be seeing around the end of october, but what we are likely to get today is widespread mild weather, with above average temperatures, even as far north as scotland. But we could see highest values of 22 degrees somewhere across the southeast thats 72 fahrenheit. And why . Well, because of the wind direction. Coming all the way up from the south, its dragging in this warmer air all the way from africa. And its notjust the uk. Large area of High Pressure keeping things very dry, very settled and very mild across central europe. We unfortunately wont see the drier weather because all the time, these areas of low pressure will bring outbreaks of rain and strong winds from time to time. So first thing in the morning, therell be outbreaks of rain across southwest england and wales, a lot of low cloud around as well. A very mild start. Misty and murky. 0ur rain becomes quite showery as it pushes its way steadily north, masking Early Morning sunshine across parts of aberdeenshire by the end of the day. But we should see an improving picture generally across england and wales. Maybe the risk of a few isolated sharp showers in the southeast, but with the sunshine, thats where were likely to see the warmth, highs potentially into the low 20s. More wet weather to come on friday, some of it heavy and windy with it, too. Not for all, but the heaviest of the rain is likely to be out to the west, and thatll be accompanied by Gale Force Gusts of wind on exposed coasts and some pretty rough seas here. Now that rain and the strong winds will gradually drift its way northwards during the day on friday, again allowing for lighter winds, more sunshine. And again, those temperatures pretty good for the end of 0ctober. More of the same as we head into the weekend. Not a wash out by any means, but there will be outbreaks of rain. And at times, once the rain passes through, well see those isobars squeezing together, the winds picking up. But there will also be some sunshine as well, so its a very messy story this weekend. Keep abreast of the forecast, particularly for sunday. But generally there will be outbreaks of rain. Therell also be some sunshine, but one unifying factor mild for all
