An increasing number of conservatives say they want to see mrjohnson secure a Second Period at number 10 downing street. In about ten minutes� time, well have this weeks edition of newswatch. But first on bbc news, click. Nearly 7,000 people in the uk right now need organ transplants. Sometimes they wait for these lifelines can be long and agonising. Not everyone survives them. We clearly need more donors. But 3d printing might be able to offer a solution. Yeah, scientists are developing a method to create organs from living tissue, which can be translated into patients who need them. Shayna 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, heart, lungs and livers are now among the 100,000 organs replaced every year. When you lose someone and theyve given the 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, terrifying time. Here in gothenburg, one team are trying to solve this, and theyre using technology thats a bit like a 3d printer. Their aim to grow organs themselves here in this lab. No donor necessary. Today we are going to look at printing skin. The skin is composed of different layers and every layer has different types of cells in combination. It is the human bodys largest organ, but even a small skin model requires millions of cells. Theyre mixed into different biolinks for the machine to choose between. We really design a code what tells the printer what to print, when, and 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 you can actually print cells or Hair Follicles to really replicate the skin. At this stage, it looks like a bit of toothpaste but actually it is seriously complicated cells in here. While 3d printed skin could be applied in surgical graphs, drug and cosmetics testing, the cells have to mature first. This is where we culture the samples weve printed. They are 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 even watch your sample through an ipad, so its no longer looking through those small eye things. Green dots for living cells, red for dead. There is not many dead cells here. Which is a very good sign. Close analysis of the end result is needed to finetune. Cellink has printed Cancer Tumours so patients can 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 printed cartilage in patients with muscle issues in just a few years. First patients are Sports Injuries because they will probably heal better, at least we think so, but also, for elderly patients or patients that suffered from osteoarthritis. We get very nice Cartilage Tissue that have healing capacity, so we are very optimistic. Further studies are needed to prove the methods are safe, but it could save time and money. It can actually print what the damage looked like before. We can actually print it directly into the knee, probably, in the future. We can mass produce it, and start with the printer and 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 we hope 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 we took a full organ, a internal organ, that will take some time. One of my oldest friends is alive thanks to a donor liver. To not have that year over year wait, to know that they would be potentially growing an 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. And, like, 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. 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, yeah, i think it would be Life Changing For Thousands of people. Theres 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. 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 its 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 just consists of a series of ipads, iphones and stands, so the cost of creating this is just the price of those items. You can also use android devices. Once the images are all taken at the same time, theyre 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. Ive 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. And here, because we focus on high quality appearance capture, the resolution comes from the reproduction of that appearance in a realistic manner in a 3d rendering. Here, we have got the 2d renders. This one looks a bit 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 up into a constituent colour texture map, a shine map, a shape map, and which captures all of your fine skin pores 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, those weird rectangles in my eyes are the reflection of the ipad. 0nto the 3d 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 were 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, and 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 whats the actual difference in resolution . This resolution is about 2k and then the full desktop setup youve seen has resolution of about ak, and as you can see, 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 theyre 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. 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. That is it for the short version of the programme.

Did the media have a role to play . And as the bbc reaches its centenary, we discuss one of its key goals and challenges maintaining impartiality. Not for the first time lately, it feels like the political temperature in westminister has been rising every day this week, culminating in thursdays resignation by the Prime Minister. There had been two more top level ministerial departures beforehand. The first being that of kwasi kwarteng, the former chancellor, only last friday. There we go. His official car is leaving downing street. He had been inside to see the Prime Minister, his former boss. He now returns to the backbenches. This viewer took exception to the coverage that followed, leaving this message why it was his car followed . His car followed all through london, Central London and beyond . That was most unnecessary, very bad taste. It was like he was being hounded out of london. On thursday, liz truss followed and the Home Secretary out of office. After watching the bbc� s coverage of her resignation ted use the word hounded for that which we heard on that news message. And in the opinion of a viewer called ch but they were compliments, too, including this and jesse added
