in the art of intrigue for what's in store, you want to go for the future for a major city to take you inside the country. did you know that even these are being factory farmed? but fortunately, there are alternatives. 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 was 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 or with optical devices, people have always felt the need to communicate over long distances, picturing so often used to carry messages to faraway places. with the invention of a telegraph, the world began to be connected with electrical. soon everyone had a receiver today information continues to flow at an ever faster rate, and it seems as though bad news travels fast as of old. how does that affect the way we react to the news? and what role does the media itself play? india and record number of new coronavirus cases on sunday. hundreds of elephants

logs being described as nonstop. bad news is the world really in such a thoroughly terrible state countries in the region. with, 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. one to talk 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 i 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.

and that him, 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 unwilling, mammoth, missing a piece of bad news might well mean that's it for you. how studies have shown that test subjects from different parts of the world became more excited and 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 of that news, especially online. and this is due to how is it a problem in 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. let us say, was the impact of media reports can be extremely strong. take the boston marathon bomb attack and 2013, for example. some people who followed the news obsessive, or more stressed and frightened than others who had been physically present. so what does this mean? first 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 so 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, be depressed or 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. as 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? so i'm asked to leave the country, journalists could ask themselves what now? fast, in addition to the usual who, what, where, when, and why. and they could pursue the matter further. do more research and advice and focusing on. so what can we do about it? before it comes to us, 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 does comes from bittorrent and you don't have to reach for your phone or turn on the t.v. or radio. as soon as he wake up, you don't have to consume information nonstop. we can be more discerning in our use of the media help to reflect your talk. 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. 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 news. robinson from colombia doesn't want to read or watch any more bad news. his way of keeping his mental health and tranquility is to try to be indifferent to it all. for rosy from costa rica, varying 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 just struck 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 something else says, if it's too false, 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 lazy is hard to define. but historically, people seen as lazy or friend to pawn in europe, at least it stems from the protestant work ethic that took root in the 18th century . in the ancient world, in contrast, exertion was scorned. philosophizing was seen as a noble craft 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 longer skin 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 is inventive the world's 1st programmable computer. because by his own admission, he was too lazy for a brick to take on. the testers didn't always feel like hunting and gathering. they would put it off until the next day, and spend the time developing new to strategies instead,

there is improve their chances of survival. according to researchers, there's a genetic predisposition to progress, a nation 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. or laziness seems to be an ace, and not just in humans. if help, what is right, why are great, but only very few. if you have a science question that's been bothering you, send it in as a video. text oh voicemail. if you love it, 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, didn't we dot com slash science or look for us on twitter, d, w underscore site tech. many mobile phones already come

equipped with cameras with built in face recognition and special recognition technologies or f r t 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 associated 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 just a short while ago sounded like science fiction. this is the year 2054 as in vision and in the movie minority report, 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 of the up 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. it is often hard to ask if the software 1st looks at fixed points on the face, on the distance between the lines, the distance from the nose to the corners of the mouth, and the features of the surface of the face, of the bombs and hollows. when i was, do you think all the data together, the profile of each face?

it's 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 and passport belong together or not. by comparing what it seems to photos, it already has it takes just a few seconds to compasses, vaillant's camera footage. with vast databases. the accuracy is said to be high as a whole lot, 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 can always because accuracy has improved so dramatically. the systems are now very,

very reliable, right? now reliable in 2017 tests, volunteers in lynn yielded success rates of 70 to 80 percent depending on the software. that's good enough for us 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? experts in generalist marcus' of the dangers 15 percent point out i was 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 lawyer 1st. that's dangerous, because it will lead to ever more surveillance if it doesn't meet with any resistance in society. 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 complex and how that reflected in our expressions is not straightforward. either. scientists at the found hoover institute in erlang 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. various aspects of the face correspond to emotions, movements of facial muscles, happy, sad, angry and so on. their own, the start of 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 time and the typical application for emotion recognition would be in the context of human machine interaction, where we have one interesting project teaching a robot to help autistic children learn to interpret social signals and facial expressions. in another areas, cars recognizing the state drivers are in whether they're distracted or feeling stressed or overwhelmed. that's all 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 is going to stop us. what

a cad cam to the team in atlanta and say that their emotion recognition system is not currently used anyway in mass surveillance . but that could change facial recognition has already revolutionized mass surveillance. says these technologies could transform 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 us is this is really happening in china. that one voice, i hope we never end up in a state like that here in germany, so much invade leaving vatten. 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 eluding detection. today, in the real world, 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 may make them more vulnerable to these natural lists. look quite different to most as martin wrongs. and antonio gurley actual run a project called be 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. the beautiful, the wild honey bees out in the woods, look for cavities and trees. they're often created by woodpeckers are formed naturally. but what we've done is create an artificial tree trunk. it's the perfect home. the bees look for the my livorno, not the beenish out. they want to find out if there are any wild beast in these woods. and if they will take a liking to the new home they are being offered a naturally occurring tree cavities are becoming ever rarer in managed commercial forests. trees with holes don't last long. they detach their log, hide 6 meters, up the trunk of an outreach base,

abs like the round shape and feel safe up there. yama good learn from the r. and b. b. . we have learned to see with the eyes of a be honest, this is not about honey or any other product, this trip. it's about having resilient be under 20 minutes to show off. and that means honeybees that can fight off parasites and diseases. an alarming number of managed colonies die prematurely, girlie actually became of the keeper in 2012, but soon became dissatisfied with standard modern methods. we 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 honey. but other bees happy. another experiment is underway in the botanical garden, in frankfort. tree 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 the 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 park. like in the beleaguered design being fork in a box hive, a colony has to work 20000000 hours more just to maintain the right temperature. or if 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 in the time in which they can do what bees

naturally do. 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 supernews, so the top levels never fall off. that makes the bees slave to their strongest instinct stocking up to ensure food security, bites of hogs or tons of cotton. that weakens down and makes them more susceptible to parasites and disease. many beekeepers lose a 3rd of their colonies each winter. so how are the bees 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 honeybees. this is what gives, it 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. if you didn't hear 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 mites. because in the tree hives the bees share their home with a natural ally, the house pseudo scorpion, torben. schiffer is a great fan of climates, but one of these tiny scorpions have long maintained. a symbiotic relationship would be nice to eat everything that can harm the beings, 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 wears an extra honey for humans to harvest accumulates. there are new frames inside the bees build their homes as they see fit. the drawer lets you check for very well might said the door provides access so that you can harvest between up to 7 or 8 kilos of honey a year, but no more. 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 do to want to scale up production of what they call natural habitat types 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 have built a huge the colony it turns out is made up of different species of be expanding. the gene pool can also enhance the resilience and adaptability, a future generations. i fall into. 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, in full, black bar log hives amount to a further argument in favor of keeping bees in a way that's good for the occupation. been out on a stick. if you become beautiful here, bees can be they build everything by themselves, no input from arsenic. if commercial beekeeping switched to these methods,

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

come up. cosmopolitan downslope, vicious brylin has never been a sex scene as it was in the pool of the 20 most modern cars shaken a sense out of finance. traces in the city to a mother's old chalfant with our little tour of the little of the corners. w.
