agents, british beethoven's 9th, the world starts to simmer down on w. . did you know that even bees are being factory found? but fortunately, there are alternatives. and we look at the dilemma of automatic facial recognition. what's more important, public safety, personal privacy, and is the world going from bad to worse? not really. but why is our brain so sensitive to bad news? that and more coming up

into tomorrow today, the science show on d. w. whether by smoke signals by pony express, well with optical devices, people have always felt the need to communicate over long distances. pictures were often used to carry messages to faraway places. with the invention of the telegraph to go again to be connected with electrical. soon everyone had a receiver today information continues to flow at an ever thought to rate. and it seems as though bad news travels fast. just how does that affect the way we react to the news? and what role does the media itself play? india and a record number of new coronavirus cases on sunday. hundreds of elephants found resupply, being described as nonstop. bad news is the world really in such

a thoroughly terrible state or country in the region. of course, the current coronavirus pandemic is indeed an extraordinary global crisis. but if you take a longer term view, you see there have been many positive trends. infant mortality has never been lower . and the number of people killed in natural disasters has been averaging downwards and talks still. we often get the impression things are just getting worse and worse, myself included. even though as a journalist, i don't just consume news, but also help shape it. that why are we more sensitive to bad news? doesn't have something to do with the brain. i'm on my way to see neuroscientist martin. she has researched precisely these questions

at him for i want to meet the brain processes negative news faster, better and more intensively than positive or neutral news on to us. we also remember it better in terms of evolutionary biology and processing negative information better than positive information has been helpful because in the age of the saber check, tiger and woolly mammoth, missing a piece of bad news might well mean that's it for you. how studies have shown the test subjects from different parts of the world became more excited and honored. as soon as they were shown, bad news, regardless of their looking shin and culture. many media outlets use this effect to their advantage. negative headlines, sell more comedies and get more clicks. the studies show that the media are publishing more and more and that news especially online is a suitable. how is it a problem? if the media rabble and bad news and ask 1st and foremost,

it makes us all have negative expectations. so we go through life with the worldview in which we assume the world is worse than it really is. to us, to toss a vicious was the impact of media reports can be extremely strong. take the boston marathon bomb attack in 2013, for example. some people who followed the news obsessive more stressed and frightened than others who had been physically present. so what does this mean? as it does, it also says my 1st of all, it makes people less likely to take action. you might think the realisation that we all have a worldview that's too negative, would actually prompt people to become more active. but many psychological studies have shown that that is precisely not the case. and i just, what's more, it can promote chronic stress. we know that chronic stress can be a factor in many diseases, including diabetes, cardiovascular disease,

and mental illnesses such as depression. how can be depressed when you doubt, if you can trust the coronavirus pandemic is a good example. after months of bad news, many people have grown weary of the crisis. they feel helpless and wish things would go back to normal. it's just a journalist. i have to consider whether i might be contributing to other people having a misguided view of the world. what can the media do better? asselin, you can see journalists could ask themselves what now fast it was in addition to the usual who, what, where, when, and why. and they could pursue the matter further. do more research and focusing on . so what can we do about it? before it comes, gets missed, it is, of course it's still important to describe a problem, but then go on to talk about possible solutions. ask people for their ideas,

always keeping in mind the question. how can we solve the problem? he can't inspired by her research, martin on a set of perspective daily, a constructive online magazine, which complements news stories with ideas for solutions. but it's not just media outlets that could or should change. we can all do something good for ourselves and our brain just comes from and you don't have to reach for your phone or turn on the t.v. or radio. as soon as you wake up, you don't have to consume information nonstop. we can be more discerning in our use of the media, helped reflect your talk time. it is also a good idea to choose media that are trustworthy and present the news in a responsible and sober manner. as a for the sake of your brain and your well being accessed the news wisely. and you can also simply take a break from it all possible. take

a break and just turn off for a while. sounds good, right? we asked you what you do to take your mind off too much bad means robinson from columbia doesn't want to read or watch anymore. bad news. his way of keeping his mental health and tranquility is to try to be indifferent to it all. for rosie from costa rica burying your head in the sand like an ostrich is not an option. she says it's better to face reality to be empathetic and help others and enjoy distract himself with nice things, watching series of films, reading books, but not too many newspapers and going outside for some fresh air to clear his head . clearing your head, that's what these people are buying to do at the space out competition in south korea.

as contestants work on zoning out. this poll says if it's too fast, just not enough noise from mexico sent in a question about that. why are people lazy and doing nothing relaxing? taking it easy. what counts as a lady is hard to define. but historically, people seen as lazy or frowned upon in europe, at least from the protestant work ethic that took root in the 18th century. in the ancient world, in contrast, exertion will scorned. philosophizing was seen as a noble cross to be pursued at leisure. a perfect excuse to be lazy. in other words, extreme laziness can be harmful even to your health. but now and then it's good to

kick back it gives us time to regenerate things. in fact, scientific research suggests that lazy people are more intelligent, they enjoy spending time spin force. other people get bored quickly and need to stimulation of activity. and innovation has often been driven by a desire to avoid efforts to comrades who was inventive, the world's 1st programmable computer. because by his own admission, he was too lazy for arithmetic. when our ancestors didn't always feel like hunting and gathering, they would put it off until the next day and spend their time developing new tools

strategies instead. this improve their chances of survival. according to researchers, there's a genetic predisposition to procreate summation and laziness. it's to do with a gene that helps regulate the production of dopamine, which plays a role in brain processes such as attention, memory, and motivation. laziness seems to be an ace, and not just in humans. the problem is right. why aren't you? if you have a science question that's been bothering you, send it in as a video, text oh voicemail. if you will, if we answer it on the show, you'll get a little surprise as a thank you. come on, you just ask. you'll find us on our website, do tell you dot com slash science or look for us on twitter at g.w. under school site tech. many mobile phones already come

equipped with cameras with built in face recognition and facial recognition technology use, or if our team can help police identify criminals and so contribute to public safety. but what about a surveillance camera with f, a r t that scans the faces in the shop, finds the associates a profile on social media and sends out personalized ads. that's not yet reality, but it's not far off. like so many things that's just a short while ago. sounded like science fiction. this is the year 2054 as in vision in the movie minority report. and it's not a pleasant scene. tom cruise is on the run, but he gets recognized wherever he goes. the film dates from 2002, but the mass surveillance is already reality. in many places. china has hundreds of

millions of surveillance cameras, many of them with facial recognition software. the state wants to know what its citizens are up to. and in germany at airports, faces a scanned and compared with the biometric data stored in the passport chip to determine whether you are really using the technology was developed by the company tech company in dresden, germany. it's a major player in artificial intelligence powered facial recognition. its products are used in automated check ins and border control systems, as well as video surveillance by security agencies. is often chartered to ask if the software 1st looks at fixed points on the face of the distance between the distance from the nose to the corners of the mouth and the features of the surface of the face as if you, the bumps and hollows. when i was doing and got all the data together,

the profile of each face. with the help of such a digital profile, the software can distinguish whether the corresponding person is standing in front of the camera or if it's just a photo. so it can't be tricked. it's smart, and it's getting smarter. even if it only gets to see part of a face, it can work out if the person passport belong together or not. by comparing what it seems to photos, it already has it takes just a few seconds to compare surveillance camera footage with vast databases. the accuracy is said to be high, but 100 percent accuracy will never be attained. but in the industry, the advances of the past 5 years have been dubbed the facial recognition revolution because accuracy has improved so dramatically and us money and the systems are now

very, very reliable, right? now reliable in 2017 tests, volunteers in violin yielded success rates of 70 to 80 percent depending on the software. that's good enough for all to consider installing such systems. so are we going to be at the mercy of the state as it deploys mass surveillance and imperfect facial recognition technology? i.t. experts in generalist mock, a speck of doubt warns of the dangers he seems important always following the problem is many people don't really want to think about these technological developments at the same time. surveillance tends to be relatively discreet, which is to say, we don't necessarily see what's going on bus stop your 1st. guess that was that's dangerous, because it will lead to ever more surveillance if it doesn't meet with any resistance in society. because h.r. 400 news, and that's not all there is now emotion recognition and analysis to

a software program that's able to deduce a person's emotional state based on their facial expressions. the feelings, the complex, and how that reflected in our expressions is not straightforward. either. scientists at the founder of the institute in airline and are using artificial intelligence to develop and improve such software. but do happy, sad, surprised, or angry faces look the same in all cultures. and for various aspects of the face correspond to emotions, movements of facial muscles, happy, sad, angry and so on. and there on the start, in most cultures, what we humans see in facial expressions, we can teach software to see as well for the very, very high degree of accuracy. and is using photos of very clear facial expressions to help train the software. but what is the point of

having it identify emotions at present? i didn't read all the time. and the typical application for emotion recognition would be in the context of human machine interaction. on this project, we have one interesting project teaching a robot to help autistic children learn to interpret social signals and facial expressions. fatalis acknowledges it. in another areas, cars recognizing the state drivers are in whether they're distracted or feeling stressed. well, that sounds pretty homeless. these technologies could, however, also be used to monitor people to manipulate them. that's one reason why it's so important to understand the technology and its possible applications, which we can only do that if we take control of it,

going to stop them and miss moving the team in atlanta and say that their emotion recognition system is not currently used anywhere in mass surveillance, but that could change facial recognition has already revolutionized mass surveillance. does says these technologies could transform our society conform. we are going to become more conformist and less free in our behavior. because in the back of our mind would always be worrying about being observed. so smile, to try to use these voters against the us. is i the reality? the less is really happening in china route one voice. i hope we never end up in a state like that up here in germany, so much invade leaving value. china has already developed a vast surveillance infrastructure and uses it to monitor each individual. the aim

is to maintain control. so, reality has caught up with hollywood. even if he wasn't famous, tom cruise would have a hard time imaging detection today. in the real world. at least let's stay in china for a moment where another dystopic vision of the future has already become reality. in some regions, fruit trees have to be pollinated by hand because there are hardly any bees left. the colonies are being devastated by diseases and crowding them in hives like this . they make them more vulnerable to these naturalists look quite different. moses martin rose and i'm tony. o'grady actual run a project called b embassy,

and they are there to be ambassadors. their mission is to create natural style homes for wild honey bees. out in the woods. here they're installing one of their log hives. it's a hollowed out section of a tree trunk. honeybees natural habitat isn't woodland. if you didn't have all the wild honey bees are no words. look for cavities in trees. they're often created by woodpeckers or for naturally, what we've done is create an artificial tree trunk. it's the perfect home, the bees look for the my livorno, not the bean is sharp, they want to find out. if there are any wild beast in these woods, and if they will take the liking to the new home they are being offered is, naturally occurring tree cavities are becoming ever rarer in managed commercial forests. trees with holes don't last long. they've attached their log hive. 6 metres up the trunk of an ultra. they say bees

like the round shape and feel safe up there. yarmulke learn from the being we have learned to see with the eyes of a being used. this is not about honey your on your other proverbs. it's about having resilient be one resistant vehemence who shot from that means honey bees that can fight off parasites and diseases. an alarming number of managed colonies die prematurely. girlie actually became a beekeeper in 2012, but soon became dissatisfied with standard modern methods. he learned about honey hunting, a practice common in the middle ages that involved making nests by cutting holes in tree trunks. he decided to adopt and update the technique. he found that bees did much better in such nests than in standard artificial hives. the question is, why standard box hives have been in use for a century and

a half. they can be stacked and the at habitants of each one yield up to 50 kilograms of money. but other bees happy. another experiment is underway in the botanical garden in frankfurt. train hives have been installed here too, and they're equipped with a range of sensors. the actual and rollers are collaborating with target shifa, a biologist, and b. expert. he's found that these round wooden hives offer bees a stable and pleasant climate. by contrast, the temperature in box nests varies a lot, and moisture can accumulate in the corners of the and there you go, leading the zambian for a colony has to work 20000000 hours more just to maintain the right temperature. or we average it out because there are 3 times as many bees in a hive as in a nest that's still 7000000 hours, extra work time in which they can do what bees naturally do. and if they're always

carrying nectar and fermenting honey, they can't get on with grooming. and that's a lot of extra stress for being. and it's not good for them. another problem schiffer has identified is that box times are too big, often 4 or more times the volume of a natural treat asked. so, keep adding honey superhits, so the top levels never fall. that makes the bees slave to their strongest instinct stocking up to ensure food security bites of tog's. that weakens them and makes them more susceptible to parasites and disease. many beekeepers lose a 3rd of their colonies each winter. so how are these doing in this tree hive? regular check ups are part of the experiment i found of a row of vero mites. are the biggest parasitic threat to honey bees that's in its shell has been bitten and sure enough,

a look under the microscope confirms the bees evidently fight back and into the viral mite. you don't see that kind of behavior in box hives to be a cause. if you can hear that these can defend themselves. they need time spare capacity to do so. but if they're always in a panic about maintaining supplies, they can't fight off the might become in the tree hives, the bees share their home with a natural ally, the house pseudo scorpion torben. schiffer is a great fan. of these tiny scorpions have long maintained a symbiotic relationship with bees. they eat everything that can harm them, but don't hurt the bees themselves. it's a micro ecosystem that has been eradicated in conventional beekeeping. complex schiffer says beekeepers should welcome how pseudo scorpions into their hives, all in all these live better lives in nests or log hives until you

also makes log hives that are suited to hopping beekeeping. the bottom section is home to various tiny creatures such as the household pseudo scorpion. the middle section is where the bees build their honeycomb and store their honey and the upper story conserve the beekeeper as a honey super where some extra honey for humans to harvest accumulates. there are new frames inside the bees build their homes as they see fit. to draw or lets you check for very well might see the door provides access so that you can harvest between up to 7 or 8 kilos of honey a year, but no more. and this is, i'm with you and it's about keeping bees in a way that's good for them. and not about honey. still in the beekeeper can look forward to harvesting a little without harming the bees, you know, through to being in the you to want to scale up production of what they called natural habitat times back to the log hive in the forest. more than 2

months have passed, have wild honey bees moved in and made themselves comfortable. but this, oh my goodness they built a huge honeycomb. all the colony it turns out is made up of different species of be expanding. the gene pool can also enhance the resilience and adaptability of future generations. this is an endorsement of our work. it also confirms the hypothesis that bees came from the forests and want to go back there. again, when full ones on the block are log onto a further argument in favor of keeping bees in a way that's good for them. and i could actually be an outdoor guy as to keeping the cunt beautiful. they built everything by themselves, no input from arsenic. if commercial beekeeping switched to these methods,

there would be lots of happy being, but we'd likely have to pay more for our honey that's all for this week. join us again next time on tamara today for more from the world of science. then stay healthy. stay curious,

no, i'm going over the centuries they come up in putin's russia has been outspoken on telly generation doesn't know how the beginning to friends. what do they think and feel is not usually like, but the nearby de niro gets to fight for peace. the plan is prepared to do everything to achieve it. here they put you in prison for a shared post. russia's millennial says it's 75 years, too old,

or not too well. what about it shouldn't come instead. a change in thinking is changing the economy to create something that the economics magazine meet in germany on t w give us your country. people will make you rich, people will provide you with jobs play, peak oil will take good care of you. less enthused as they claim fever took hold on the west coast of qana in $2700.00. investigators made promises, but here's later, reality looks very different. the 1st beaches
