i didn't, i see the sign was part of psychosis isn't awful. illness. postpartum is a nasty mothers nightmare starts june 4th on d w. 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 flee and eternal life as an abbot talk what is already possible in the digital parallel world. all this a mo, coming up, ah, hello, and welcome to,

to morrow to day the science show on the w. in order to spill in easy leg experienced justin bieber up close and personal. maybe that's not everyone's dream, but here it's possible with his digital avatar. if you're not on board, 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 the game fortnight is considered one of the biggest and most expensive avatar events. over 12000000 people attended the virtual concert . mm. virtual influence is not based on specific human role models or another trend in the avatar market. like vill mikaela. please make your st. we'll 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. well, as i like to call 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 of 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 dismayed to us. so much responsibility and so little time to study or explore free. good, 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 t scan of holocaust survivor ava o mouth. at one of europe's 1st volume metric video studios with vina farm delay. we were the last

ones for our transport went from said it where we were then transferred kelly von from navarre key to auschwitz, sna ousley. no mother was of normally when you create 3 d people for games or other environments, hundreds of people are involved to simulate clothing that will hair huffman real people in 3 d i or paint them. that's all god in the recording room here. i can walk in, shoot like with a normal camera, press start, stop, and everything's in moving photo realistic, 3 d. and that's the real game changer. what's new about this technology on these? i totally 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 man. it's nicely of bending. is this more realistic in suite?

i mention, i see it's important to me that this be preserved for future generations. the on at highland, if this form of technology enables that, that it's fine with me better than is the semi, sorry, not doc swim bleed on can place 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 lager or smaller. and now i'm really in the normal video with him. and so another person can stand behind me, record videos with me and share them with other friends. for example, the name on judgment on on florence hospital. 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 i never did was i could imagine experiencing her as a hologram at a grave site as he done oh, and others experiencing this too. so you could really see this person buried there,

although there are lots of exciting application scenarios out of the new scenario. application scenarios that still seems strange. yon phillip stein explores the effect of virtual figures. can we truly mourn the dead if we still meet them digitally? if permission, good fortune. i imagine that we're just at the beginning of something new as a man kind of developing a different view of technology for from 5th young, 50 years ago. many things that are normal to day. we're still creepy and scary dumb it will then chocolate thought. i don't want anything to do with that on the for them, you can see even now that younger generations use technology quite differently than older ones too often a tool is our own gung, i think a natural way of dealing with it will emerge over time and maybe it will be a good way for people to still feel a connection to those who have died on if have been known so soon. but where's all this lead to long in the future? will our consciousness also be uploaded to the da little world?

think the amazon series upload, portrays just such a scenario. welcome to upload nathan made it's a late fee, the lucky duck o during accident, the main character nathan gets himself upload range of the cloud and leaves as an avatar in an animated luxury resort. some kind of old fashioned room over a lake, a realistic scenario, freeze manufactor. i know how that's right now. we're still quite far from it for ya. so anyone who claims it'll be possible in 10 years or so that's nonsense. it's clicking 20 or 40 or so years into the future. the way machines systems, data storage office and everything are developing the can fit. 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. it's

still really science fiction. when it's, i mean everybody dreams about it, but i'd like to see it happened 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 remains just an illusion, hulu. in the real world, different rules applying here, having to leave, especially during times of war, is the 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 new cancer therapies. ah,

the city of leon is the 3rd largest in france after paris, and must say it offers a high quality of life. it's also a popular city to study in the clouds. bernard university is a hub for science medicine and biotechnology. over 40000 students are currently enrolled here. hi lina whose nets over is from ukraine. together with her colleague natalia, do benco. the biologist fled the russian bombing of keith and arrived here in march . in so walk or mortally be thought over what they brought 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. virginia, 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. our 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 keith and see for been the decision. right, right. you're studying nano particles and they impact on cell culture. 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, or lack of life more. we have a why chill 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 video because there's a deep understanding of funding mechanism,

so subtle of so life of cancer genesis above the action of potential drugs in i'm so proud and so excited in we're not, we could actually win the fight against cancer in the near future. horrible. helena and natalia will also play crucial roles here, especially during the projects next stage. when the nano particles will be tested on mice. they are here because they are excel and very good restaurant experience 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 on about the go 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, i know her husband alexander a physicist, had to stay in cave. 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 or by not because of the conditions, but because they're at brutish from their lives of vision. and 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 was out 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 have with them. but 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 maybe not now, but in the future was the truth is probably somewhere in between. lou deals

river lesson a bridge close to traffic leads to the old town i for the to researches the sites here are a reminder of their own home city and what they had to leave behind yard. the caution they mused, i'm an operator, most of you and i heart and believe very much that will return to give more work go provide him with. we shall absolutely need to go about because a big part of my life is that you 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, flux of beds and most to piece of mass coordination. each bad can initiate

a maneuver and the flux will follow fish even have an extra organ to avoid colliding. the lateral line open with it, they can proceed when the pressure around them changes. ah, the head is also important for many mammals, especially if they have to my great 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 eigen. it's about understanding what happens in a crowd like that with lots of people in by feeling mentioned pos, yet. methodist on the physicist armin's eye fleet,

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, cuz i'm vexing. come. 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 the mom. 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 had. in some experiments we measure hydrate and skin conductivity, finding its home to figure out how stressed the subject. so he and his test because the ones in the main reason for crowding is high motivation in unfavorable spatial

conditions. the larger the crowd, the more dangerous the situation is, the course of being of 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. yoga 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, under the effect demand, 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 am 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. it's a concept steeple, who gets in somewhere fast,

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 you mention, 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. amanda. 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 with what sort of emerson, by league that are 100 voice. if people are highly motivated to leave in overcrowded place, chairs 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 destined. 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 associate pastor ideally should have a steam. what if,

what am i losing or what is the motivation? what does it work 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 rules are ne 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, besides 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's 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. they're fight i buy up at i'm only the advantage of monitoring waste water is that it gives us data on everyone who's infected, since 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 plants catchment area, we can also find fragments of the virus that infected people excrete into the waste water in a buffer. so we can catch on reported cases too, as not every one knows that they're infected or gets tested, infect you on, on that and get tested. the sewage at the treatment part 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 a corona fire sampling was we want the larger bottles for our assembling on our daily checks, which is the pause in this large bottle will be kept frozen for a month. so we always have a reserve 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 coven 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 the girl, the other in 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 south wootton thinks it's already a success. as it's o s. d infected people actually start shedding the virus on a few days before they develop symptoms and to begin the other house i. so waste water allows you to recognize much earlier where the trend is heading a canon ward at went hint it as a that gives us head start at roughly 5 to 10 days. first with st agen zion'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 cove it waves? the results should prove useful even once the pandemic is over. but mostly that's going to ok. now we're going to extend this to other pathogens. it's about, for instance, to use it to monitor influenza or polio which continue to be problematic, not before. so we hope to gain experience here. that's about how that can work in practice. as i talk practice often cindy on cotton, currently the waste water samples from across germany, the to 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 said, from tomorrow to day d, w, science program, feel free to tune in again next week until then. state curious. ah ah ah ah ah ah
