subject on presenting money and making gatherings safer to morrow to do i do w. we've got some hot tips for your bucket list. ah, magic corner tread hotspot for food and some great cultural memorials to boot w travel off we go. oh, 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 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 john on board with him. 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 market. like vill 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 nearly an hour at all. well, as i liked all my safe a, a digital twin of the physicist albert einstein to bring him to life as an avatar. an actor 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, ousley num, otherwise of normally when you create 3 d people for games or other environments, hundreds of people are involved to simulate clothing with 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 the normal camera, press start, stop, and everything's and moving. photo realistic 3 d. and that's the real game changer . what's new about this technology on these? i 4032 cameras capture, eva. i'm left down to the smallest detail and a computer uses this data to create a 3 d hola gram. if. if the spirit is i image is different, man,

it's nicely of bending is, is more realistic in 3 dimensional humans. the, it's important to me that this be preserved for future generations. and hi, and if this film 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 thicker or smaller. and now i'm really in the normal video from food. 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 retiring. 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 to fight 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, although 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 still creepy and scary. dumb it will and chokes, thought, i don't want anything to do with that on the 5. and you can see even now that younger generations use technology quite differently than older ones. still in

a truly how own gung, 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 leading to 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 minutes late fees, 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 manufacturing. okay, that's right. now we're still quite far from it for. yeah. 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 ervish. now 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. when that's, i mean everybody dreams about it. but i'd like to see it happen some day that option exists. so whether you want it or not, it's a dream that is 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, was a sad part of everyday life. these to reset his, had to leave the ukrainian homeland. the 2 scientists fled from their home

town of cave to leone in france. there at least they can continue their work research into new 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 co been i university is a hub for science medicine and biotechnology over 40000 students are currently enrolled here. hi lina whose net silver is from ukraine. ah, together with her colleague natalia deblanco, the biologist fled the russian bombing of keith and arrived here in march, insult, walk up mortally. this proposal what 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. 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. a biology lab at the university. the law center good to renew your problem. the 2 are already part of this european project while in keith. and they've been sent right back to studying nano particles and their 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 as the technology, high powered microscopes that allow cells to be studied in depth, 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 their catalogue

. more we have a why kill ideas my sure it would be in that, in this model with here we're on the threshold of developing a revolutionary treatment of living because there's a deep understanding of fundamental mechanisms of cell life, of cancer genesis of the action of potential drugs in which in i'm so proud and so excited, he will not, we could actually win the fight against cancer in the near future. 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 experiment experience on animal studies. okay? and this is good point for us because of the know how to do it, go fast and swipe down on the, on the global vision of the project can produce no, no, but the good to test them. we do it the step we study on. so good 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. aah! i asked her husband alexander, a physicist, had to stay in tif or helena made the decision to take her children with her to safety to leon. they live here on the campus. on up, her leg is 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 up rooted 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 here or daughter soon, and 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, but 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. lou leo's 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 ya. the course shook the news. i'm and i'm getting most of you and i heart and believe very much that will return to give more with global garden with we sure absolutely need to go about because a big part of my life is that you are who are you this? when that does happen, natania 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 bad can initiate a maneuver and the flood will follow. fish even have an extra organ 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 on the physicist armin's eye fleet and his team have 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 in 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 known 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, another effect demand. another effect that you get from these queueing systems is that things are fairer dasa 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 forces such as a seat on the train or a certain place to stand. it's a concept 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 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, our 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. farm 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 that whatsoever, misson by league, the dot 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 for each team is working to develop such standards, based on their experiments distancing rules help, though not always, associate pastor ideally should have as his team what, 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 distance injures 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 source covey to virus leaves us traces that can reveal mold. it not only gets into the mouth and lungs, but also into the intestines. and finally,

into the toilet or mm hm. it's a trail that every person leaks behind all the way to the sewage treatment plant, where it can be collected and analyzed in the bar. lou 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 ins. irelands 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. therefore, i buy a better money. 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. heisman becomes ethically, since we get human waste from every one of 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 to nitrate concentration and p h value . an auto sampler collects 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

a lot of your through of local warner will as follows. for corona virus sampling was given the larger bottles for our sampling of our daily checks with walls and this large bottle will be kept frozen for a month. so we always have a reserve sample on amongst a wall or most to ago, susanna latina 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 one of 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, rigor rubber 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 supp hooked and thinks it's already a success. as it's all this di, infected people actually start shedding the virus on a few days before they developed symptoms and to begin the oven our size. so waste water and i want you to recognize much earlier where the trend is heading a canon, ward at hint, hint it as a back gives us a head start of roughly 5 to 10 days from within tagging 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 country's 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 too much 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 practice often in young 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. ah, that's it from tomorrow today, d w science program. feel free to tune it again next week until then state curious with
