a and a south bay mother is going to spend the rest of her life behind bars from marguerite per $3.00. if you call me back, i do with i see the sign was part of psychosis is an awful illness to have to post fordham 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 plea and eternal life as an other 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. and we're the 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. it's a, during the corona virus pandemic, the trend towards virtual concerts, but avatars became stronger than ever. he was rather travers scott's appearance in a 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 tray in the avatar market. like

little mikaela, please make your said 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 or as i liked all my things, if possible. 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 facial features recreated on the computer and indeed the einstein avatar is as funny as real life predecessor. i am the president. ah, i am sorry to hear to be president of anything. he said dismayed to ask so much responsibility. and so little time to study or explore free. living 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 some babylon bag, visual effects experts are making

a 3 d scan of holocaust survivor eva a mouth at one of europe's 1st volumetric video studios with really fine delays. we were the last ones for our transport went from said it where we were then transferred. henley devonne from navarre key to auschwitz know how silly no mother was of normally when you create 3 d people for games or other environments, hundreds of people are involved to simulate clothing the would hair of a real people in 3 d on or paint them. that's all god in the recording room here. i can walk in shoe like with a normal camera, press start, stop, and everything's in moving photo realistic. 3 d, w. that's the real game changer. what's new about this technology on these? i totally 32 cameras capture eva o mouth, down to the smallest detail and a computer you is this data

to create a 3 d hola gram. this is the spirit is i image is different now it's nicely a bending is it's more realistic in 3 dimension. i see it's important to me that this be preserved for future generations. yeoman at highland, if this form of technology enables that, that it's fine with me. beat that done is to, to me very not, don't swim bleed on, can police the volumetric holograms into any environment such as mixed reality apps on smartphones come get slain. 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 food food . so another person can stand behind me, little record videos with me and share them with other friends, for example, of name on judgment, on, on foreign social retire. 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.

haven't guns on em, it's all have a very different relationship to the past. the lives of one that doesn't end right when someone dies might. if i scanned my gramma, i could have her with me in my living room each day or whenever i want. 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 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 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 with and chokes, thought i don't want anything to do with that on the for them, you can see even now younger generations use technology quite differently than oh,

the ones do in a truly how along with it. 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 died on if have been known so soon. but where's all this leading 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 o. after an accident, the main character nathan gets himself uploading to the cloud and leaves as an avatar in an animated luxury resort. he some kind of old fashioned room. okay. over a lake, a realistic scenario, freeze manufacturer, and okay, 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. but you can say that at some point will likely reaching 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 5. it still really science fiction on it. i mean, everybody dreams about it, but i'd like to see it happen some day, but that option exist since 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, is a sad part of everyday life. these to reset has 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 also a popular city to study in the clouds. bene, university is a hub for science medicine and biotechnology. over 40000 students are currently enrolled here. hi lina, whose net silver is from ukraine lou together with her colleague natalia, do benco. the biologist fled the russian bombing of keith and arrived here in march . in so walk or more to leave to go over what they brought to be able to continue scientific work. it's crucial to preserve my mental health plan. and those of us

live in such a stressful and painful situation via i have to keep my mind and my hands busy. of all this work helps me live duck mexico. ash the core of helena and natalia's work is here. a biology lab at the university below frontier could cover your literature from the 2 were already part of this european project while in keith. and they've been sending him right back to studying nano particles and they impact on cell culture. but this is for, for, 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. were reca left the upper why shall i d 's my sure, it will be in that, in this model 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. horrible. helena and natalia will also play crucial roles here, especially during the projects next stage. when the nano particles be tested on mice, they are here because they are excellent, very good, the strong experiment experience on any more 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 none of 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 really 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, oh ok. ah, 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 up her like these. 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 little, they're uncomfortable here or by not 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 here or thought was auto soon, and irish 25. today 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 vito d a dog. 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 when 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 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 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 back because a big part of my life is that you are you this when that does happen, natalia and helena a 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, that, ah, now we move on to something more airy, flux of beds and most to piece of mass coordination. each bed 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. 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 ice lead 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. erin, 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 them. um, the scientists linked these code to body data. participants fill out questionnaires

about how they feel in crowded situations. their inner state of mind is assessed to divert method, he hats and some experiments we measure harddrive and skin conductivity, finding exposure 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, course among of them in a large crowd of 2 and 3 or 400 people can't. i can't help it at all, just come your gun is in the midst of idle so i can't even get to the middle as the crowd. so dance that there is no way to intervene. oregon will answer card. one solution is narrow access routes. 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 good as for 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 a concept standard staple, who gets in some way 1st, then fairness becomes incredibly visible. on the 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, but 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, shar, 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 animals, keep certain distances, know their place and react automatically action 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, 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 to fall into 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 i and body in a crowd on co carpark and mixed 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 freedom team is working to develop such standards based on their experiments. distancing rules help, though not always yet vast hello should of his team. 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 karone of ira's distancing rules are 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 current of ours 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 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 covey test results. therefore, i buy up as a 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 placement compact. thank you, since we get human waste from everyone in the plants catchment area, we can also find fragments of the virus that infected people excrete into the waste

water in a bath. so we can catch our reported pace is to, is not everyone knows that they're infected or gets test. it affects you on, on that and get tested. the sewage at the treatment plant is already tested for harmful substances, nitrate concentration and p h value. an auto sampler lacks 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 lot of your through look all over google as follows for a current fire sampling was given the larger bottles for our sampling of our daily checks would as it was and this large bottle will be kept frozen for a month. so we always have a reserve sample on the lowest level. oh, most 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 founded in waste water. her method could even detect how quickly different variance of the virus was spreading in a given area. the da who got one of the data could be used to estimate the infection rate in the plants catchment area and decide whether to test more covert 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 supp hooked and thinks it's already a success. as it's all this

d infected people actually start shedding the virus on a few days before they develop symptoms. and megan, they're on our side, or waste water allows you to recognize much earlier where the trend is heading at canon. ward at hint, hint it as a lot, if this head start of roughly 5 to 10 days, 1st was 10 tag and czar lands 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 most of us can 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 that before so we hope to gain experience here, kathy, about how that can work in practice. as i talk practice often,

cindy and 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's it 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 ah. with climate events what could the future

bring in 75 d w. m. small acts can inspire big changes, meet the people, making it on ease, go africa joined them as they set out to save the environment. learn from one another and work together for a better future. ah, maybe talk to you all, but tuning it africa on d. w ah, welcome to the dark side where intelligence agencies are pulling the strings. there was a before 911 and after 911 he says after 911, the clubs came off where organized crime rules. every

genuine is a global network of companies, banks, and operators who will provide those services to anyone. operation in the criminal economy, where conglomerates and make their own laws. they invade our private lives through surveillance, hidden, opaque, secretive. i've worked through what they it doesn't matter. the only criteria is what we'll hook people up. we shed light on the opaque world who's behind who benefits and why are they a threat to us all opaque worlds start to june, 2nd on d w. ah

ah. this is the w news live from berlin. ukraine says russian forces are advancing on the center of the arrow tonight. president plugin is zalinski, says russian bombs have almost wiped out the eastern cities critical services as he makes his 1st.
