open your eyes to be on the scene. our new global $3000.00 series, about the threats you're facing, the heroes taking a stance. it's not that i have to be back up until the global $3000.00 theories start june 21st on d w. the me ah d w. news and these are our top stories in israel far right liter. enough, poly bennett says his party will try to form a unity government with prime minister benjamin netanyahu that rivals the decision could jeopardize netanyahu's future by enabling liberal politician and former finance minister. got your la pete to create an alliance. it comes after

ah, the welcome to global 3000. life begins at 70. we find out why many older people in japan, shoving the idea of retirement, waste disposal in south africa. we learned how a small stance up is moving mountains when it comes to recycling. first we go to the rain forests of brazil where illegal gold mining leads to deforestation and the destruction of natural habitats. gold is one of the most valuable precious metals on us and also one of the most desirable whether is jewelry as a commodity or is an investment. the gold price has been rising for years,

is seen as a safe asset during periods of economic come certainty, like now with the corona virus pandemic. recently the gold price hit $1500.00 heroes for troy amps. but how much gold is there on our planet? the world gold council estimates that the total amount of mind gold would fill a cube with nearly 22 meter long sides. almost half of it has been turned into jewelry. 22 percent is private investments. well, 17 percent is held by central banks. the remainder is found in electronic devices like smart phones. it's not known exactly how much gold is still in the us. the one thing is mining it is becoming an increasingly complex task. most consonants can boast large scale gold deposits, including south america. in brazil, gold mining is having a devastating impact on both the rain forests and the people. ah

. for despite the pandemic and rainy season down cause he's out serving his territory more and more often he comes across illegal gold mining ross . they cruise that probably is simply notes that location as a police don't. bag with water mostly drinkable now. i believe it's a film, the oil on it and the mercury they use sinks to the river bed. we consume it through the fish week when it makes us sick. fish which luggage them through his territory is this forest protected. make sure with the illegal loggers and cold minus to increasingly encroach on the missouri indigenous peoples land. don't care about that. teach worry suspects. it's because the price of gold

has shut up during the pandemic intruders have kept this new path through the jungle. they start by logging the valuable trees, then they plow up. the soil looking for gold. chief suarez is worried is yanna had given way to see this year. we've increased our patrols on sunday because we can see there are more intruders that you might judge of us. and it's dangerous for us. because demick means we're forced to take over the work of the environmental police and fire, even though it puts our lives at risk of according to his could you my little gold prospectors on never, far away. some prospect legally outside the nature of others. invade indigenous territory. because there are hardly any patrols there at the moment.

in chief's ramirez village, the wonderful to maintain their culture and traditions. oh, they're nice revolve around the rhythm. the they have done for centuries, but they also maintain ties with the rest of the own cell phones have the public school and are in regular contact with environmental organizations. the min douro says i was did the appeal of the gold rush. unlike most other people in the region, lee will read in the city all the gold mine of the rental. again, they will send the, the man god to counselors, and even the sen body. that's what makes them so powerful. not stems from faith.

working by the mayor is also a lager and a gold mine of them. as we leave the village, we pass more gold, mining ross, and some wreckage. a dam is scheduled to be built in another trip to the indigenous way as long 3 hours longer with andrew and different provincial capital. tuba has been the epicenter of the gold rush here for 50 years. it's thriving despite the panoramic prosperity based on the high price of gum. it has to be may, it says that's why there's hardly any unemployment here. despite the corona, virus crisis is currently doing his official work from home privacy. he runs a network of companies including gold mines color. thank you put.

busy him on the bus and our government has to regulate our goal of mine. so people don't have to work illegally anymore. all these cars are only legal minds can be property regulated. my saw my both in that anything else drive the miners into legality with no right to the shortage to kind of go on like this. and they, it says the mercury pollution isn't a serious problem. ill. so got a bit of there's a little bit what i've been mining goals since i was 18 a minute that i don't that are covered 3 tons of goals and then the mercury is never effected me in all that time. no one was submitted and there's no technology which could replace the use of mercury or unless you're in the country capital for president j your vote. so nora is the main supporter of each to best gold mine. he re should one negation that he was working to allow mining even in indigenous territory. he's already drastically paid back environmental policing

and penalties. west clay to mice was a delegation member, has been lobbying to legalize the gold mines for years. thousands of them are about to be licensed retrospectively for now. only those outside protected indigenous territories. west clay to minus says its progress. follow with my sure scenario talks a load of rubbish, but he also does some good thing, but you'll get quite that we visited him 7 times and brazilian will soon see a load of gold mines legalized at last. this is very clear. he says that from pictures of his license goals, mines outside protected areas and says the gaps they left in the jungle will be reforest. it was she is, has his doubts about that right now his tracking some intruders

they pass is marked by sono bronte. ah, they arrive at a tree trunk flowing across the channel. the patrol can't get any further with about the size. they have a lot of them, but we won't make it all the way and we're running short to feel as well. it's not not going to get them in a box. it's an age old story. nature's guardians are numbered by better equipped invaders. and so then, our territory, if we stop to patrolling altogether and relied only on the stage, we soon lose the entire area to the criminals. some of the criminals who seem to have gained the upper hand, aided by the pandemic. o

2 children, one giant problem in the near proceed. you may be jason doing related how will climate change affect us and our children learn more v w dot com slash water. in this leak in global ideas, we go to south africa, a country like many others plagued by trash. waste separation is read that over 90 percent of general waste ends up in landfill sites. that's something the top regina eyes wants to change its on a mission to get the country recycling reports. julia yaki mess up with the visionary waste ex

marshall of our sorting and packing up her waist plastic from the past week in time for a special pickup service. recycling household trash is still the exception here in cape town. washing byron's only started separating her paper and plastic recently as part of a pilot project. and they may be alive. you know how bad things was until i started saving place. i have never, never thought about it, but i'm so glad to be doing my best. and every little bit counts currently just 7 and a half percent of south africans recycled their waste. the result is mountains of plastic and other refuse across the country. until now the only form of household waste recycling here was done by informal

wasted collectors. chad robertson decided to take action right there. we got a lot of legal dumping quite a big issue and skipped on board and some stuff around were spending on 400000000 or and a year on a legal dumping and getting it up. we, as you know, we produce sitting in money and rather creating solutions to solve this problem right beyond the landfill. there's no dumping, sign on it. it's actually not really, i don't if it goes at most dumping sites you will see, you know, dumping sun. so it's quite an old saying kept on in, robertson wants to encourage keep counters to bring about change. his regina start up is primarily aimed at people from the poorest parts of the city. south africa is a very unequal society and that extends to waste disposal. if you're in

a low income community, for example, there's really nothing available for you besides the informal conflict because we've collected recyclables because the private companies wouldn't operate there, nor with the free service operate. as i mentioned, that's on the new upper income communities. regina eyes, which he founded to help resolve keep towns waste problem is located in the bridge town suburb, in the east of the city. in 2018, the start up launched a pilot project here tailored to the needs of lower income areas. me see them or who may begin their shift as a collection point, while one starts sifting through and sorting the items from the past week. the other sets off on his cargo tract. steve m. o, who may, does a tour of the neighborhood once a week? yes

yes, the service is a new one for the residents of bridgetown. see them who may collect paper, plastic and cans from participants. meanwhile, 500 households are taken guard today. he'll stop by 150 homes. he makes a careful note of how much each sack weighs. his strikes. cargo gauge builds up quickly. residents involved in the pilot project aren't charged for the pickup service. to the contrary, participants all receive a fixed, some in remodeling for each waste to pick up remotely as a virtual currency that can be saved up and then spent on shopping vouchers, mobile phone, data, packages, and donations. thank you so much. oh, i need to buy dog food,

so the thing go do the dog food. when a man who may makes his way back to the depot, the project provides jobs for people who used to be informal, trash collectors and unemployed young people like to see my who made me his colleagues bring the sorted reusable materials to recycling plant, where the waste is turned into a new resource. regina is his efforts, have won it a national social innovation award. those support from the local authorities has been sluggish, especially when it comes to creating the infrastructure for more collection points . but chad robertson and his team are undeterred. ah, we are still pushing. the optimism comes there are small things, you know, seeing the impact that it makes seeing positive review some customers and being

able to grow the business as well. the vision is to really scale our service could are done in africa. recycling model and get people not going to recycle, but living was circular. or should barnes is a convert? she's happy about the vouchers, but even happier that she's now doing something about the waste problem. people will come, career lies that we all need to do something to make the change. be the change you want to see be the change and i'm glad that i got thoughts. it's late in life, but i got started rather late than the regina team are hoping that the government will also increase support. so that recycling can soon become available to all south africans. anytime it's renowned for its many local delicacy,

we headed that for this weeks labels indonesia is the world's most popular country. more than 300 ethnic groups live here, which makes for a rich and diverse cuisine. live in total market in the capital jakarta offers a wide range of traditional foods. it's where mister mums, you are, makes his care lactaid on a hearty dish. that's a specialty of the baton we people. the one i started showing carol taylor here in 1981 right is the 1st ingredient. the rise is allowed to soak overnight so that it cooks more quickly. other ingredients are coconut,

washroom flour fried charlotte's ground pepper and shredded coconut. then come the eggs. customers can choose 2 chicken eggs or one duck egg. then the pan is turn over. the charcoal fire that helps give the tailor its special flavor. in the end, if topped with 2 spoons of spiced shredded coconut and a spoon of roasted challenge the that i really like it because it's very delicious. i've always like cataract hello patel. we food and i'm battalion the before the pandemic. mr. monday or used to serve up about 50 portions a day. now it's just or 480-0000 rubia, the equivalent of one euro will get you a portion made with

a duck egg with chicken eggs. it's even a little cheaper prices in the character hello year, a very flavorful. it's not like the character hello made and other places where the seasoning is a bit careless. this character lower is especially delicious. mister monday are also sells his character as a takeaway dish bone up a tea or some mark on the healthy diet. that's one way to stay fit into old days. according to the un, there are more than 500000 centenarians on the planet retold. and the number of people over 65 is set to double by 2050. we had to a country with a particularly large percentage of elderly people, japan and many of them have no intention of taking it easy. in their old age,

he kept enjoying his retirement. after all, to yo keiana is 70 a sprightly member of what japan calls the silver generation. depends population is aging, so the country is putting pensioners back to work to you, your model used to be efficient. now he proves trees. i enjoy the work and it keeps me fit. plus it's a welcome of money on the side, we do get a pension but not a big one. and so i really do need to work with a lot here in coaching prefecture, more than a 3rd of the population over 65. in the regional capital, many shops and business with the aging population. there's no one to take over and keep them going. so yuki yadda used to run his own restaurant,

but the number of diners started dwindling 10 years ago. now he's traded in his sushi knife for a chain so ah, and things are looking up. he's self employed again, but now ends with far more lucrative, 20 years an hour, though the quality governing the train, young people, not far from here. nicole going up the musket all because someone i know started learning how to prune trees, but then quit. i call that default ultimately. so i asked why and he said he didn't enjoy it. probably because it meant working with so many old people. yeah. to say the house that the garden belongs to is vacant. the original residents are probably deceased or in the retirement home. they family pays for the upkeep. the owners are gone, but the garden continues to flourish. you know, you're going. yeah. oh,

that's the fishmonger. he's always driving past here. and it always gives me a scare. it's almost enough to make me fall off the ladder. did that? i thought. i like me cold. she is beautiful. but aging, it's home to japan's oldest tram system, dating back to 19 of 4. and rather fittingly, the traffic is directed by the news. the old red light district is out of business . the love hotel now lies in ruins. in the city of co, none. it's back to school in what's called the center for silva. human resources, somewhat daryl name for a job. agency serving retirees we have tree pruning is taught by mr. hammer ada, who is 81 along with training. the center also helps with job placement and takes

care of the tax and insurance side you are. it's one of hundreds across the country, all funded by the authorities. the elderly recruits emerge as bus drivers, parking lot attendance and even garden, this little boring wow. luck wouldn't know. i didn't know the, the older generation have to pitch in. life would otherwise come to a standstill due to the departure of the younger population. the expectations are really high, but with us they can work without any pressure and contribute something to their region. with him. right outside the center is a wooded park where the budding gardeners can get some practical training. these 9 trainees, or between 61 and 78 years old. mister cars, ocoee the oldest of the group used to be a cook in a hospital so that the main thing is i get some exercise and stay healthy. everyone needs money and i only get my pension every 2 months. now you

know much and it's getting smaller. where does all that money go? i guess that's a political issue again from that day to say that you are mr. young. the former sushi chef also graduated from the silver generation center. busy he, there's been 6 years learning on the job as a volunteer holding his patients and precision the same skills he brought to the sushi business that up but, but the wheel don't simply cut off what's on top. you started, the root will not get there. if you only trim the top of the army oak, it would look rather odd no matter what a couple of times mister jamita has mastered the art and now trains other scene is mister august, is 78 and is wriggling in the new challenge. because i got him all,

i'd been mowing meadows fancy trying a tree pruning. i don't have my own to semester. i'm out provides them. he's teaching me so much and he's a really nice person. he thought if mrs. jamara has also joined her husband's new enterprise. she's on the books of the silver generation agency as a cleaner. but when her husband's workload becomes too much, she lends a hand for a wage. but i work together with my husband. so when we've hiding something up, what i feel happier right away with customers also thank me that the results are so lovely. it is good and it makes me happy with them all so good. another work day draw to close. so mr. young could have borrowed tools from the job agency but insisted on having his own just as he did as a sushi. but they will always been a stell joe,

for the old days walk, i'm on. there's only old people here these days. you hardly ever hear children now, and there are lots of vacant homes for an hour neighborhood. people get old and die, but their sons and daughters don't want the houses. they called on the adults and then i got our ear no hands to keep pruning for another 10 years when he'll be a t. it's a job with a theater. japan maybe aging, but the trees continue to grow. ah, that's little from us that global 3000 and thanks for watching. what did you enjoy about this week? so let us know at global 3000 and d w 's outcome. we love hearing from you. don't forget to track us down on facebook to d w global ideas. bye for now. take cast. the

the, who's the ah, this is to understand the world better. we need to take a closer. oh,

the knowledge. moral. no matter how's the or flashing kind of or how would it take to become iconic? take a look at pop culture, that is a global post ask, how can we 60 minutes on w o the news or we can william connors can effect the climate change. i mean, one for

a station in the rain forest continued carbon dioxide emissions have risen again. the young people all over the world are committed to climate protection. what impacts willing to be whose change doesn't happen on his own? the make up your mind. w. 4 minds the. busy think it is unique to an individual pattern of riches and sorrows that can reveal more than just your identity when a thing that makes even just please in contact with a surface, at least traces of fact self and proteins that can now be analyzed using new technologies that health scientists identify someone's eating habits

the disease, and they suffered from or whether they took drugs even centuries after the fact the following fingerprints into the past and rediscovering history. welcome to tomorrow. today the science show and d w. busy repositories of knowledge, centuries old books can teach us a lot about the past, as long as we can decode them. cryptographers have yet to decide to the 15th century voyage manuscript. for example. historical books, dominique, as well as intellectual secrets, secrets about the people who wrote them, touched them, and left their traces in the form of proteins. these molecules are found in every single cell of the body, and each type of protein is made up of a sequence of amino acids folded in

a unique way. scientists have only recently learned how read this data hidden between the lines of old the so called marker polo bible is almost 800 years old. tiny flavors. if the parchment roll biochemist pierre giorgio regard, you needed to look into it and past regrets. he speciality is proteomics the study of the range of proteins in organisms. he examines documents, paintings, clothing for traces of proteins, and they can be thousands of years old. teresa for the bible belongs to the laurentian library and florence its name dr. marco polo, because he was taking it to china to the court of crude like con, but what kind of parchment is it made of? back then paper had not yet been invented. surface had been examined with instruments like spectrophotometer using ultra violet and infrared light. and so on,

but then we proteomic systems came along and examined the proteins. there was a theory that bibles from the period were written on parchment made from the skin of lam fetuses. it turns out this one was non calfskin blues were again, he says it's a type of parchment that was only used until the middle of the 13th century in the south of france. this new method, together with textual analysis, have revealed the bible's origins. no, one of the little wrench in library had ever heard of proteomics before. quiz that we have it, i mean to know this was absolutely new to us. we get to hold the academic world. our researchers and experts are manuscripts. something that was completely unknown to them, something we always wanted, that's a physical analysis of our document, e fees and i bet re guest. he had a problem. he needed samples for his pershing analyses. and most libraries and

museums refused to allow precious works to be damaged in any way. but a solution was found to re guess he's problem. and it came from israel. ah, any televi sub silberstein, originally from russia, conduct proteomics research. as soon as he heard about re guess, he's work with marco, polo bible, he wanted to get involved. i go here, we go, give how you cause a can extract result is result to destruction of object one. think 2nd, think our to closing make pretty a concentrations means of increase concentration of proteins. and if that's no per sham on that said, if you want to keep on examining cultural heritage, we simply cannot continue these destructive technologies like a renaissance gene coming up with avant garde idea. really,

silberstein has invented plastic films containing beads of charged resins that jewel proteins and other chemicals from objects they're placed on. the extracted proteins can then be analyzed in the laboratory, his latest cruise and examination of one object casanova. his manuscript. it's great to lower this molecule quote, portrait jack, i'm working on this just because on the one side from cazenovia mem was to the shirt anton check off with wearing when he died. little by little silberstein and his team working their way through the literary canon, me another exciting discovery is what he found on a manuscript by russian writer may count lucas cost me waste was a q, do kudos, which was a source of such could be in will get for much more

good. the answer was found in traces of sweat on the manuscript. drugs read shows the highest concentration, green, the lowest ball because it was a short time when the v get the people found the objective for information about races. so for direct appear with in the particular morphine in the for the booker, for papers held us dine sent the extracted proteins to rigatti and milan in his lab. but the polytechnic university, the plastic films, are dipped in a chemical solution that detaches everything that has stuck to them. the enzyme trips and breaks down the proteins into smaller peptide fragments,

which are then analyzed by a mass spectrometer. and major breakthrough by the protein historians had to do with the history of melana itself . half the city's residence died in a plague epidemic in 1630, where he wanted to find out what the death registers still in existence and kept in the state archives might reveal. with silberstein films, he examined the lower right margins of several pages and found that they both traces of sweat bacteria, tobacco, and food, are pretty cameras on a protein, a protein that data that are passed. course we examine proteins associated with play bacteria. but we also found out that not everyone died, 2 percent of the victims died of anthrax. with this research in which we identify proteins because we have, in a sense, brought back into life. the more through the mario risen from the grave in which

they were buried 400 years ago. we brought them back to me. it's quite incredible. equest no my own causes. there would be pierre giorgio regret, he says purging historians could rediscover all world history in an antiquarian bookshop in florence. he recently found this book published in venice, centuries ago. ah, probably did. she said he would probably find all kinds of bacteria, epidemics, traces of cholera typhoid who knows, you know, some personnel mix could become one of the most exciting sciences of the future by casting a new look at the past. the scribes publishes and readers have left information about themselves as traces of proteins on the pages of proteins are found in the sweat. the body produces limits

under stress. and proteins may play a role in the somewhat pungent smell of sweat. but in fact, stress plays a vital role in humans survival. since prehistoric times, stress has helped humans to survive. when a predator approaches our brain sounds, the alarm and releasing the stress hormones, adrenalin and cortisone. adrenalin gives our body a sudden energy burst. our heart rate and blood pressure rise, that pump some more blood to our muscles. the stress hormone cortisol is released soon afterward, acts as a stimulant, breathing blood sugar levels suppressing the need for sleep and reducing our sensitivity to paint. but in the long term, it can ravage the immune system. adrenalin and cortisol that give us energy rush and activate the fight or flight response. afterwards, our body needs to rest and recover. today's stresses different often it just

doesn't stop. constant state of high alert can lead to chronically high levels of cortisol that can make us sick and weaken our immune system. it can also promote obesity, high blood pressure and cardiovascular disease. the good news is plenty we can do to pete stress, including breathing exercises. when to try to. ready sit down, close your eyes, take a deep breath, feeling how your belly expands as air fills your lungs. quickly . studies show that conscious breathing reduces stress levels. but there is another unexpected factor that affects how we deal with stress. and it has to do

with where we grow up. this fellow is a typical city kid who didn't spend much time in the countryside or have contact with animals. this guy, by contrast, grew up surrounded by nature. he had lots of contact with farm animals. research shows that people who were raised in the country are less likely to have certain mental illnesses, particularly growing up on the countryside is actually associated with a much lower risk of getting depression. so are people who grew up in the country also better at coping with stress to find out, say by the team, conducted an experiment they simulated a job application interview with 40 male test subjects. but i'm thinking the, the why do you think your, the best candidate thing? well, because of my previous experience in the school, interviewers didn't just listen quietly but intensified the pressure by asking the

candidates to do some mental arithmetic on the spot to count backwards from 3269 instead of 162-3221 stop for for the wrong police. start again from 3200. 69 on the subject. didn't know the interview was not for a real job. getting the answers right was not important. the experiment was about something completely different than it is. and stand up to here, it's a standardized test. it's only purpose is to put people under stress under experimental conditions. festus, i think practical classroom of 20 of the test subjects grew up in a city and have never had contact with farm animals. the other 20 spent at least the 1st 15 years of their lives in the country and had lots of contact with farm animals. it's already been established that that has certain health benefits

as it's, i mean if i let you know that with regard to allergies, an auto immune diseases, it's been known for years that growing up in the country protects people from them . and even after lunch, i'll fix both thinks there are further benefits. residents of rural areas have contact with many non harmful micro organisms, better prevalent in and around animals in their dung, posts, and feed researchers call them old friends isn't and it's a colorful of bacteria argue bacteria, viruses and single cell organisms. all of these micro organisms that were present during our evolution are referred to as old friends. cba and his colleagues 1st identified the effect of these old friends in experiments on mice, annoys and tag with the mice. we've demonstrated that when they're treated with

these good microbes, there are less susceptible distress. for example, we can prove and chronic stress from causing intestinal inflammation or increased anxiety in the mice tight. now, who does that also hold true for people who grew up in the country. the researchers use the fake job interview to try to answer this question. before the test, they took saliva and blood samples from the participants. a particular interest where the stress hormone cortisol, which is produced by the adrenal glands and released in greater amount just when we experience stress and decided kind interleukin 6, which is also released when we are stressed and it stimulates inflammation. high levels are associated with a whole range of illnesses since the inflammatory bowel disease and inflammatory disease of the joints, and as to the emotions and with depression for examples or post traumatic stress disorder, and in zion disorder, sunken before the experiment,

cortisol and interleukin 6 were present at normal levels in both groups, the city kids and those who grew up in the country. after the test samples were taken, the cortisol level proved to be the same in both groups. that means they experienced the test situation as equally stressful. but how did their bodies deal with the stress that the researchers looked at the white blood cells, glucose site, they produce the classified kinds known as interleukin, including interleukin 6 produced in larger amounts when we're stressed by this as the number of white blood cells and the number of inflammatory cytokines released were higher in city dwellers than in those from the country. in 2 hours after the test researchers drew blood again to see if the into look in 6 levels had dropped and were returning to normal. the results were interesting via the city residents weren't able to regulate their interleukin 6 level. that means

it can knew to rise over the 2 hours after the experiment constant. but those from a rural background were able to bring the level down within the same time period. why was the 2nd group able to deal with stress more swiftly? professor says it has to do with the old friends. a contact and it didn't make contact with these micro organisms enhances the regulation of the immune system. the rise and interleukin 6 was less pronounced in those with a rural background. and so those who had a lot of contact with animals reduce their interleukin 6 level and by implication their stress level more quickly. it's not yet clear whether rural microbes are the only reason for that could extended contact with a pet dog or a cat eel. the same positive effects reba and his team. want to find that out. ah.

so many of us, one of the most stress inducing cases is the office. just as we're trying to rise and impose and email the phone rings, guys, and then a text message pings on to your cell phone and you have a meeting to run to. it's impossible to concentrate and get anything done done also . but how could come from computers, thanks to emotion recognition software? shadley mar, loan is a software developer. his work involves a lot of complex tasks. it should be strenuous and sometimes kind of depressing when you can't figure it out. then you are in a bad mood and his colleague mathias schmidt. my also spends a lot of time in front of the computer. often these multitasking,

worst case scenario, it hits you all at once. the entire de la various stages of things. you could sit down and say, monday i'll do only the one thing tuesday. the other in practice though that's difficult. they both work for tony a company that is looking to develop an intelligent software system that automatically supply staff with only as much work as they can complete the employees have to wear a pulse moment while on the job. a video cam films their face said that the supposed to monitor their mood and emotional state based on that data, the software will decide how much work they can handle. at that moment, marco maya helped develop the software. he's looking at charlie's data to try to figure out how his colleague was feeling about his work right then. and what his emotional state was like. this, you know,

if you find the task difficult or easy was he may be at risk of feeling over extended, over a longer period. ah, to figure that out, the computer will have to learn how to interpret emotions in a blog. my is one of the test subjects. she's assigned a stressful task. she has to re type various texts. what she doesn't know is that the text will get increasingly difficult. first, she gets the children's story. then a text with complex chemical formulas. the pulse moment to get feedback on her stress level. at the same time, the camera monitors various facial muscles that indicate emotion, like a corner of her mouth, all the area around her eyes. riggins expression is eli neutral, but not quite. often on the right side, you can see she's under stress,

we just saw the line is trending upwards. what that means, really speaking, is that the task is a challenging one. and before that, she's getting more stressed and on. the other thing that's very interesting is that the video also that's his draw conclusions about her heart rate, is her heartbeat, regular, irregular, fast or slow. based on various insights from medicine and psychology, we can draw some conclusions about stress levels. the demands being made on her or relaxation. so even though her expression might be nutro poker face and she might still be feeling stress on the inside and you know the flight of anger sponge is. do we really want to that a computer peers so deeply into our mind and soul phillips is alec from the german research center for artificial intelligence. has his doubts. ah, and what is this is used as a form of surveillance, perhaps even with repercussions for the employee,

that if someone's performance seems sub par, they might be fired about maybe because they're going through a tough time on a personal level on the the system might detect that, and that could have negative repercussions for the employee, and that's something we definitely don't want to see germany. it's illegal to monitor employees this way. without their permission. will they always have a choice? marco maya says his only goal is creating an optimized work atmosphere system. for example, it would activate, call forwarding and moments of intense concentration. which is what many people say is that technology now serves as a major distraction. there are so many different channels of communication. email messenger, social media, so especially at work it's getting harder and harder to work on. something in a really focused deep way over a longer period. and it's almost like it's become harder and harder to achieve flow

to feeling of energized. creative focus is a switch to the state that's often described as the optimal balance between boredom and feeling overwhelmed and stressed. it's that midpoint where i feel challenged, but can still master the task of that flow to finish the flow. during the stay to flow brain releases, happiness, hormones, heart beat small rhythmically and skin conductance increases. ah, marco, my wants to use these responses to teach computers to be aware of our emotions and to assign tasks to work as based on what they can master. that's at the moment philip susanna also believes that systems like some other useful applications. for example, in traffic and on the road. it might involve

a train or autonomy is driving system where we want to know if the locomotive engineer or the driver is still alert and awake. but there might also be beneficial applications in office settings or provides the company has already carried out tests in real life offices. the results are still under wraps, but it's already clear that systems like this opposed to change how we work if i was what is read, why do you have a science question? you've always been mulling over every week. we are through a query session via us this time it comes from the ria increase the what is a black hole?

black hole are among the weirdest objects in the universe. there traps in space time where gigantic amounts of matter are compressed to a point so massive that it curves space almost infinitely, and brings time to a standstill. the border of this bizarre world is known as the event horizon. the german astronomer college font shield did seminal calculations of the defining parameter describing the event horizon. black holes are formed when massive stars collapse at the end of their life cycle. or when the compact remains of dense stars merge downtown, the lightweights among these gravitational traps are born. they're called stellar black holes. those gravity ranges from between a few times to some 10 times that of our son media. massive black holes can have up to 100000 times the solar mass. and the really giant, super massive ones look at the center of many galaxies millions,

even billions of times as massive as the sun. black holes grow by sucking up everything and there vicinity and even light can't escape the gravitational traps. and they merge with one another to grow. the albert einstein predicted them in his general theory of relativity in but they were 1st detected around 90 years later in the center of our galaxy. the milky way is one such invisible mass that accelerates nearby stars. to incredible speeds, ah, telescopes around the world were synchronized to capture the 1st ever image of a black hole. the relatively spectacular looking picture shows the place where time comes to a standstill. the dark event horizon surrounded by a ring of light from the hog matter. the orbits of the black hole. it was

a milestone in astronomy. me to send in your questions, just go to our website or find us some switch. ah, that's it for this week's edition of tomorrow today. thanks for watching. we'll be back next time with more stories from the world of science and technology until then stay healthy. and the, the, the the the, the

the the, the the ah, no matter how's the horn or flashing kind of ours, how would it take to become iconic and take a look at culture that is a global pros ask,

how can we 2030 minutes on these w o the little guy that is the 77 percent. the platform is used to be issues and share ideas. you know, we are not afraid to capture and africa. correlation is willing and young people clearly have the solutions, the future. 77 percent. now every return on the w.
