the news that shows battles the issues shaping the continent life is slowly getting back to normal. yeah. well the streams to give you in the report on the inside our correspondence is on the ground reporting from across the continent. all the frames doesn't matter to you. t w, lose africa every friday on d w. sometimes the best thing is just write out at you. our tv highlights in fresh in your inbox every week. snap them up. a massive groups of people, how to avoid disaster. we take a look at crowd research. also the war in ukraine is affecting the science world as well. we visited to researchers who had to plead and eternal

life as an abbot talk what is already possible in the digital parallel world. all this a mode coming up. ah, hello and welcome to to morrow to day the science show on the w. in order to spill in easy, then go experience justin bieber up close and personal. maybe that's not everyone's dream. but here it's possible with his digital avatar, it's, you're not going to spread to like, you know, during the corona virus pandemic, the trend towards virtual concerts, but avatars became stronger than ever. he was rather travis scott's appearance in a game fortnight is considered one of the biggest and most expensive avatar events . over 12000000 people attended the virtual concession. virtual influence is not based on specific human role models or another trend in the avatar. all kids,

like little mikaela, please make your st. will avatars make it possible one day to meet people who have long since died in the real world. i am not so he'll albert einstein merely and ha, ha ha. well, as i liked all myself, a husband, a digital twin of the physicist albert einstein, to bring him to life as an avatar and actually rehearsed einstein's gestures and voice, then his face with features the recreated on the computer. and indeed, the einstein avatar is as funny as, as we alive predecessor, i am the president. ah, i am sorry to hear to be president of anything he said, dismay task, so much responsibility. and so little time to study or explore fi letting the dead live on as avatars. for now it's still experimental, but in the future technology could change the way we look at the past. in put stumbles back visual effects experts are making a 3 d scan of holocaust survivor eva

a mouth at one of europe's 1st volume metric video studios with visa, farm the legs, we were the last ones for our transport went from said it where we were then transferred henley, devon from navarre key to auschwitz, our city num, otherwise of normally when you create 3 d people for games or other environments, hundreds of people are involved to simulate clothing will hair huffman real people in 3 d on or paint them. that's all god in the recording room here. i can walk in, shoot like with the normal camera, press start, stop, and everything is in moving photo realistic 3 d. and that's the real game changer. what's new about this technology on these? i told you 32 cameras capture eva. i'm left down to the smallest detail and a computer uses this data to create

a 3 d hola gram. this is the spirit is i image is different now. it's nicely i've been big. is this more realistic in 3 dimension? i seem to think it's important to me that this be preserved for future generations . yeoman and highland if this form of technology enables that, that it's fine with me. beat that done is the semi fairy not doc swim bleed on, can police the volumetric holograms into any environment such as mixed reality apps on smartphones come get slammed. i can place myself anywhere in the room. i can turn around, make myself linger or smaller. and now i'm really in the normal video with him, so another person could stand behind me, record videos with me, and share them with other friends. for example, of name on judgment on importance was retired. he believes that in the future mixed reality glasses will replace smartphones will be able to view 3 d hola, grams at any time. so even the dead can continue to visit us in everyday life.

kevin guns and it's all have a very different relationship to the past that i live at. one that doesn't end right. when someone dies. my, if i scanned my gramma, i could have her with me in my living room each day or whenever i once i wish i could imagine experiencing her as a hologram at a grave site. it on. okay. and others experiencing this too. so you could really see this person buried there. there are lots of exciting application scenarios out of the new scenario, application scenarios that still seems strange. yon phillip stine explores the effect of virtual figures. can we truly mourn the dead if we still meet them digitally? if commercial, good fortune, i imagine that we're just at the beginning of something new as mankind is developing a different view of technology for from 5th young, 50 years ago. many things that a normal to day was tilt, creepy and scary. dumb it will and chokes, thought i don't want anything to do with that. you and the father, you can see even now that younger generation use technology quite differently than

all the ones to natalie. how along with it, i think a natural way of dealing with it will emerge over time. and maybe it'll be a good way for people to still feel a connection to those who have died, you know, have been known so soon. but where's all this lead to long in the future? will our consciousness also be uploaded to the digital world? the amazon series upload, portrays just such a scenario. welcome to upload nathan made it's a late fee, the lucky duck. oh, or an accident? the main character nathan gets himself uploaded to the cloud and leaves as an avatar in an animated luxury resort. has some kind of old fashion room over a lake, a realistic scenario, freeze manufacture. i don't have that right now. we're still quite far from it. we are, so anyone who claims it'll be possible in 10 years or so. that's nonsense. it's looking 20 or 40 or so years into the future. the way machines systems,

data storage drivers and everything are developing mixes. you can say that at some point will likely reach complexity where something like that will be possible vishna that we can basically store ourselves somewhere as a back up and then have a kind of eternal phase. it's a long term goal. people have been working on this kind of thing for ages 56, it's still really science fiction. on that. i mean everybody dreams about it. but i'd like to see it happen some day. that option exists since whether you want it or not. it's a dream that has yet to become reality. for now. life as an avatar, we means just an illusion, hulu. in the real world, different rules applying here having to leave, especially during times of war, is a sad part of everyday life. these to reset his,

had to leave the ukrainian homeland. the 2 scientists fled from the home town of cave to leone in france. there, at least they can continue their work research into near cancer therapies. the city of leon is the 3rd largest in france after paris, and must say it offers a high quality of life. it's so so popular city to study in the could been i, university is a hub for science medicine and biotechnology over 40000 students are currently enrolled here. hi, lena, who's in yet solver is from ukraine. ah, together with her colleague natalia do banker, the biologist fled the russian bombing of keith and arrived here in march. in so walk up mortally withdrawals about the price to be able to continue scientific work is crucial to preserve my mental health among those of us. in such

a stressful and painful situation via i have to keep my mind on my hands. busy of all this work helps me live luck, mexico. ash. the core of helena and natalia's work is here. a biology lab at the university the law center could give me a little problem with the 2 were already part of this european project, while in keefe and c for been right, right. you're studying nano particles and they impact on cell culture. what this is for food ah, you see. but this hands on experience in the lab, in leon, is new for them. so is the technology high powered microscopes that allow cells to be studied in depth? and the ultimate aim of the project is to help detect and treat cancerous tumors

without the harmful side effects of chemo or radiation therapy. were a couple of more the upper why shall i d, 's, mom? sure. you be in that in dismal go with here. we're on the threshold of developing a revolutionary treatment of the menial because there's a deep understanding of fundamental mechanisms of cell life, of cancer genesis of the action of potential drugs in i'm so proud and so excited and will not. we could actually win the fight against cancer in the near future. a little helena and natalia will also play crucial roles here, especially during the projects next stage when the nano particles retested on mice . they are here because they are excellent, very good. the strong experimental experience on animal studies. okay? and this is a good point for us because of the know how to do it, go fast and swipe, go on the, on the global vision of the project can produce nanoparticle to test them. we do it

the step we study on central job, but they're of important because what they're doing on animals is real conditions. it's exactly what will happen when we read this on humans. the work and life on the campus provides a welcome distraction. but the situation in ukraine is never, far from helena's mind. ah. okay. ah, her husband alexander a physicist, had to stay in keith or helena made the decision to take her children with her to safety, to leon. they live here on the campus or not personally like beach. the most difficult thing for me is to see that my children are far removed from their familiar surroundings and routines. far away from their friendless that they're uncomfortable here about, you know, because of the conditions. but because they're up rooted from their lives of

visions, they asked me every day when we'll go back to care for them. but i can't say, because i don't know over him or thought, assume that the irish 25 to day the scientists decide to take a day off campus and explore leon a little with their kids. the 17th century town hall on plastic to hall is a landmark in the city. as is the dramatic font san bastardi. i wonder what the talk isn't only about the weather and the architecture in helena and natalia, who have worked together for years admit that their discussions often revolve around that cancer research. not really a passion that their children share. we often argue about different approaches to cancer. we both had the same scientific mentor,

and his viewpoint is that cancer is not a disease, but rather an evolutionary process. we can't avoid it and we can't concord so, but i agree with that. but helena doesn't, she thinks that we can eradicate cancer with it. maybe not now, but in the future was the truth is probably somewhere in between the old river lesson, a bridge close to traffic leads to the old town. i for the 2 researches, the sites here are a reminder of their own home city and what they had to leave behind yard the course of the news i'm and i'm getting most of you and i heart and believe very much that will return to give more work overburdened with we shall absolutely need to go about because a big part of my life is that you are who are you this when that does happen, natalia and helena determined to take back the know how and skills they've picked up in leon to help strengthen the development of science and research in ukraine,

ah, now we move on to something more airy, flunks of birds, and most a piece of mass coordination. each bed can initiate a maneuver and the flux will follow. fish even have an extra oven to avoid colliding. the lateral line organ with it, they can proceed when the pressure around them changes. the head is also important for many memos, especially if they have to migrate long distances like these carridy. but what about as humans? queues, train stations shopping st. grounds form in

a variety of places that's often unpleasant and sometimes even dangerous. happy. what makes it an ideal topic for research is kit agnes. it's about understanding what happens in a crowd like that with lots of people in by feeling mentioned pos, yet. methodist only a physicist armin's eye freed and his team had been studying this topic for many years. to learn more about people in crowds, they simulate various crowded situations with around 1500 test subject. participants squeezed through simulated drain doors, or stand in line for concerts. every movement is meticulously evaluated. evelyn exams, i think um we have 16 cameras and toto hang on the la clothing ones that hang from the ceiling to monitor people's colored cabs and the codes on them. um the scientists to link these code to body data. participants fill out questionnaires

about how they feel in crowded situations. their inner state of mind is assessed to wonderful method he hats. in some experiments we measure hydrate and skin conductivity, finding its home to figure out how stressed the subjects are. he and his test because the ones and the main reason for crowding is high motivation in unfavorable spatial conditions. the larger the crowd, the more dangerous the situation is in the course of many of them in a large crowd of 2 and 3 or 400 people can't. i can't help it at all. is community limited by little, so i can't even get to the middle as the crowd. so dance that there is no way to intervene. you will answer one solution is narrow access route, q management systems that deliberately constrict spaces. experiments show. this doesn't lead to over crowding. on the contrary, another effect dim on another effect that you get from these queueing systems is that things are fairer, does as crystal to get. because inequity can be

a cause of over crowding that come to him done and i'm not, he on off does nothing. this comes into play, in particular, when it comes to the distribution of resources, such as a seat on the train, or a certain place to stand. if i can't set standard staple, who gets in some way 1st, then fairness becomes incredibly visible. on go up with this back, especially during the karone of irish pandemic, it became clear, equitable q management systems help us keep our distance. wait signals, clear signage and path markings lead to less over crowding. that's crucial in spots where space is limited. if we have enough space, we orient ourselves intuitively, for example, along the lines of sight and keep a certain distance from other people. the seemingly random distribution on the

train platform is by no means random, as we mentioned, torn so as people act like they're standing somewhere quite randomly. in reality, that spot is chosen quite precisely because for example, people always stand the same distance apart and under. oh, we choose equal distances because we don't want to crowd our fellow human beings, nor should the distance between us be too great. when things get crowded, people seem to behave like a heard at 1st glance. but unlike animals, humans like the tools needed to intuitively orient themselves in a dense crowd. taylor m d m. far animals. this exhibit swarm or hud behavior have a kind of innate repertoire of behaviors that help them react in that situation. they pay attention to the other animal that keeps certain distances, know their place, and react automatic clayton as humans. we simply don't have that programming from and must create meaning for ourselves in that situation. then we have to consider

how to react to what sort of emerson believe it or 100 voice. if people are highly motivated to leave an overcrowded place, chaos can ensue. individuals feel overwhelmed and things get dangerous, like at the love parade, to those and 10 induce burg, western germany when tens of thousands tried to reach the exit all at once. some fell and were trembled by the masses. was the son that's a few of us mentioned that leads to people just losing their footing, falling to the ground and then not being able to move because of the crowd and ceiling these next to them. and so one goal of these experiments was to see exactly how these people use their legs, arms high and body in a crowd on co carpark. and what's them using this data. the researchers try to determine how much freedom of movement feet need at what walking speeds to prevent falls. because though countless large events have been held,

there's still no standard to predict when a crowd will get out of control, or how many people must be involved. xy friends team is working to develop such standards based on their experiments distancing rules help, though not always a few fast, ideally, should have a steam. what if, what am i losing, or what is the motivation? what is it worth for me to act this way at the highest? if i have to wait for 2 hours for the next train, then it might seem to me that the corona virus distancing roles aren't worth very much. but experiments also show that people do not always feel uncomfortable when they're packed in like sardines, after all, there are situations where we want to be part of the crowd because it's only human to seek proximity to others. despite the possible dangers.

the corona virus pandemic has also illustrated one risk of crowds infections. but it's not always clear how many people have been infected in an area. still, the sauce covey to virus leaves us traces that can reveal mo, it not only gets into the mouth and lungs, but also into the intestines. and finally, into the toilet. mm hm. it's a trail that every person leaves behind all the way to the sewage treatment plant, where it can be collected and analyzed in the laboratory. ah, this shows completely without swaps. how many people are infected with the corona virus and with which virus variant as well? another valuable use of waste water. this is waste water.

it comes from sa, brooklyn, in western germany and is purified at the largest sewage treatment plant insulins. 25000 cubic meters of waste water on dry days. enough to fill more than 130000 bath tubs. though in rainy weather, that amount can triple tina follow tomb conducts wastewater analysis. recently, she has been checking sewage samples for the corona virus, believing that this could be a better way to detect rising infection rates than coven test results. therefore, i buy a better money. the advantage of monitoring waste water is that it gives us data on everyone who's infected, says everyone has to go to the toilet. and everything we excrete ends up at the sewage treatment plant member comp. since we get human waste from every one and your plans catchment area, we can also find fragments of the virus that infected people excrete into the waste

water. him up us. so we can catch on reported cases too, as not every one knows that they're infected or gets test it in fact you on, on that and get tested. the sewage at the treatment parent is already tested for harmful substances, nitrate concentration, and ph value. an auto sampler, that's a bottle every 2 hours. benyamin voice examines the samples at the same time each day. an extra sample is now taken twice a week for the corona virus monitoring pilot project is of lottery us rules. look all over google as follows. for corona prior sampling was we want the larger bottles for our assembling on our daily checks with support and this large bottle will be kept frozen for a month. so we always have a reserved sample on the lowest level. almost 2 years ago, susanna lightner from the technical university of darmstadt, found that sampling wastewater can show how quickly and widely corona virus has spread through a region back then she and her team was searching for an early warning system,

for covey. 19 waves and found it in waste water. her method could even detect how quickly different variance of the virus was spreading in a given area. that wasn't mother, the data could be used to estimate the infection rate in the plants catchment area and decide whether to test more, coven testing or less, and whether to relax cove. it restrictions depending on wastewater values with her and my boss of him. many countries, including the netherlands, spain, and the u. s. quickly adopted the system, in part because it's cheaper than conducting hundreds of thousands of individual coven tests. now, 20 german municipalities are taking part in the waste water monitoring pilot project. even more had applied to do so. tina follow tune from sutton thinks it's already a success. it's, it's all that d infected people actually start shedding the virus on

a few days before they developed symptoms and torment began the oven outside. though wastewater allows you to recognize much earlier where the trend is heading a canon, ward at hand hidden good. otherwise, if this a head start of roughly 5 to 10 days, within tag n. z, allen's proximity to france is another aspect of the project. french waste water is purified and now monitored here too. so is the influence of the countries, different rules and restrictions on cov, it waves? the results should prove useful even once the pandemic is over, but mostly as counter. okay, now we're going to extend this to other pathogen, mr. barbie, for instance, to use it to monitor influenza or polio which continue to be problematic. not before. so we hope to gain experience here, kathy, about how that can work in practice. as i talk practice often to the uncut,

currently the wastewater samples from across germany that are being tested for the corona virus. a sent to a central lab by mail. it's hoped that eventually testing could be done on the spot . then the results would be available even more quickly. that's it from tomorrow to day d w. science program. feel free to tune in again next week until then state curious . ah ah aah! with
