supre in the dying seconds of the match this corner kicks stayed out of the net. it did leipsic with the hard for when but don't expect berg's goalkeeper geekier bitch to forget it any time soon. leipzig next set their sights on a champions league date next week against liverpool. thanks so much watching news and stay tuned for that $1000.00 special. the fight against the corona virus pandemic. has the rate of infection been developing what does the latest research say. information and context the coronavirus update coming 19 special. on t w. children to come to the hands of one giant problem and move it in no need to see the.

entirely legal features included in a flu shot to get it. passed how will climate change affect us and our children. learn more about d.w. dot com slash water. accused of being super secret is denied play dates and locked up in the most important developmental stage of their lives. the bad day makes hit kids hard. but the new german study shows they're not the main culprits in passing on the coronavirus. the attrition 0 edging schools and kindergartens to reopen warning of a lost generation added norma's psychological costs whole society.
4:17 am
will get to the findings of that study i mentioned in a moment when we talk to the specialist behind it 1st calls from children's organizations here in germany they want the government to do more to support kids through this crisis. i real quick about it friends now feels like a fantasy for children like 9 year old luna growing up during the pandemic has often meant missing out. the hardest thing is spending days weeks and tomorrow without having much contacts of the peoples of contacts to do. that i mean you can change my character a bit. i've been lonely without anyone to do things with.
4:18 am
and i've really missed. it. before the pandemic around 30 children would come to this after school club in berlin every day now they're making do with $1.00 to $1.00 activities for a couple of hours a week. some relied on the club for a hot meal to make sure they don't go hungry director bianca's on the feds prepares 10 to 20 meals a day for the kids to collect. but most things children need can't be packed up to take home. from an educational perspective it's be encouragement we give every day that is being lost that's what's really difficult at the moment we can't carry out our everyday work in terms of inspiring the children quote showing them new perspectives. and the conversations we have here often open up a whole new world for these children and if that's not possible right now that's really start with us. is. does not polwarth. the
4:19 am
crisis has hit children from poor families especially hard one in every 5 children in germany is growing up in or at risk of poverty with a household income of less than 60 percent of the national average but they often have less space at home like the equipment they need for online learning and restrictions have made it harder to access supports. the children growing up in poverty this is a very hard year a last year when it comes to the education and social device. that meant and they just won't be able to catch up at all right now so it's important that we support these families now and don't wait until the crisis is over with. because of a. child's head can't be put on ice for all children's resilience and adaptability this period will have long term consequences. you honestly is a specialist in pediatric infectious diseases and joins us from germany's
4:20 am
university hospital that spoke what's your stance on the closure of kindergartens that's something you've actually investigated. we are who we feel good are and should be reopened soon as possible children are not to the fire off the epidemic they are not a major transmitter of the new coronavirus of a shoe and if they get the wireless they have only one complicated unfair injection it can we already rule out though that daycare centers and schools are sources of infection. yes i think we can we have in which to get it here in 9 child care institutions need to continuously investigated asymptomatic children who are as it is those daycare institutions in the last autumn and winter and also we did several sawzall swaps and so.
4:21 am
we were not able to indeed defy any major problems for almost actions in these situations so definitely we couldn't exclude you. who were resisting this is usually nature's source of infection isn't it possible though that asymptomatic kids continue to spread the virus over a matter of weeks if not even longer. the asymptomatic case yes they should have the wires so what we did we rested it is those children who were dramatic and we could not find the wilds so only you know and a handful of cases among several scientists so i don't see that asymptomatic children contribute to the spreading of the virus in the population it's a just explain to me what do we know about the disease process in children and
4:22 am
parents. and only when we know our children and that if they get infected by the new coronavirus they usually get all the light of every infection without any complications no name very small part of children mostly like older children round 10 years who might have complicated than a tory complication the so-called martin from a tory systemic syndrome. this is an exception. but it is a relative specific for the new coronavirus so. i was just going to jump in based on what your saying what what would your advice be to parents then who have to work who want to take their kids to a can they got no one to let their kids go on a play date that's been denied them for so long.
4:23 am
parents should explain bit shy children the general rules which still are 1 effective in the population keep just sense and regular early white those close contacts according to the regulations because. we cannot because we have to see the family as a not as as an or whole group and we cannot make any exceptions for you know smaller children in the family all the children it would be too complicated to keep one actually year. well he is. well to recommendations for all but but you want to keep it simple the fact is though we've got a whole generation of kids growing up here in a very different environment what about the psychological effect on these kids.
4:24 am
the psychological effects should not be underestimated. if children do not have regular contacts to their age related peers to all there are into shima like childcare institution kindergarten and primary school secert an early miss an important piece which is important to lend your logic to develop man too and that this is what we as pediatricians feel and therefore of course the whole that the childcare institution can then be open soon and as i said before i don't see a problem in this because in the child gets it usually. there is no major infectious to cizik to the d.
4:25 am
by the new coronaviruses so far ok thank you very much for talking to us your highness liza university hospital visits both department of pediatrics. thanking. for the last time this week it's over to our science correspondent derrick williams he's been fielding your questions on our you tube channel. if you have already had kevin 1000 do you still need to be fact in a tent. yes healthcare authority is recommend that you do assuming of course that you've completed your isolation period and are symptom free but that blanket advice is also evolving and growing more specific as we move forward with vaccinating growing numbers of people for example a number of studies have indicated that naturally acquired immunity in nearly everyone who had the disease really is effective for at least several months we
4:26 am
expected that but it's still reassuring to have the assumption backed up by evidence during that period re infection appears to be very rare so if you've had copd at 19 recently it almost certainly won't hurt to wait a while for the vaccine the experts say and that will increase access to vaccines for people who haven't had the disease during this this critical stage of the pandemic where the vaccine production still vote and other factors could also influence future advice for example in a recent study looking at this topic that's still awaiting peer review the authors found that after a single dose with a vaccine people who'd already had copd at 19 had antibody responses that were often more powerful than what 2 doses tossed in people who'd never had the disease
4:27 am
and and that powerful immune response to a single shot was accompanied by more heavy duty side effects like the t.v. can and fever and headaches as well which. in people who have never had the disease usually come after the 2nd shot so the debate has begun on whether it might make sense for those who had copd at 19 to be dosed only once which would also free up more vaccine for people who haven't had the disease but at this point with data still limited a lot of experts say it's really better to err on the side of caution and stick to the to dos regime used in the trials for everyone until we know more in the german city of pasto is offering his customers a different kind of injection you can't have negative news about vaccines the must the confection has created the jam jap it comes in various flavors and is injected
4:28 am
into freshly baked goods you can even get a vaccination certificate old loyalty card 21 stamps and you get a free dose of jack. that's a lot of our notes thanks for watching stay safe so you can see. the controls our bodies could soon operate our computers to. the brain the most fascinating borg him in the human body. why remembering is hard work how software can read our thoughts and how the chaos in the brain can transform the creativity of the journey through the cosmos of our heads tomorrow today. next on d w. cinema should be celebrated
4:29 am
since a greaser may had its 125th birthday. for the movie industry is in a crisis which has been exacerbated by corona. will the movies ever be the same and if so with an arch $21.00. 30 minutes on t.w. . it's about billions. it's about our. kids about the foundation of a newborn daughter the new silk road. china wants to expand its influence with this trade network also. china is promising new
4:30 am
chargers rich. but in europe there's a sharp morning never accept money from the new superpower to become dependent on the beach chinese game with your. starts feb 19th on d w. the human brain is thought to be the most complex organ in the natural world it has over 85000000000 neurons. and a newborn baby actually has an even higher number. throughout early childhood the brain continues to develop as does the memory. even the most powerful computers can't match the human brain in many respects but computers are being taught to read brain activity allowing a human being. to control them merely with the power of thought.
4:31 am
well come to you tomorrow today with an exploration of the human brain and the world of thought. our brains are constantly working take vision for example we see football a shot to the right. the ball is our range. our eyes take in what we see that information is passed by the optic nerve to other parts of the brain in the form of electrical signals these signals can pass through the brain's neurons at a speed of up to 120 meters a 2nd. at the connection linking one neuron to another the signal has to bridge a tiny gap known as the snap to cleft before continuing on. there is no one central location in the brain where
4:32 am
a thought is developed we think by an entire network of neurons distributed across the brain. so detecting a single thought isn't easy but computers are learning to do just that. getting ready to play a very special computer game one that doesn't require the use of your hands a game that slowly powered by your source. if it was their 1st so it's really interesting to try this out for myself and when i think that in 5 or 10 years time we could be turning the oven of the lights on and off at home like this it's pretty amazing it's not respond is this the future we've come to the sensory motor system a slap at the e.t.h. institute in 06 switzerland scientists here are studying how humans and machines can interact with a video game as a connected to the. an editor via
4:33 am
a headset that can read the brain's an electrical signals to those on this device consists of an electrode which is a conductor that can detect changes in frequency very well if we think about wanting to carry out of particular movement and that triggers electrical activity in the brain just small differences in frequency that can be measured by this electrode. right now the electrode can only detect 2 commands concentration which causes the characters to speed up and relaxation which slows them down the players have to respond deliberately. when i want to concentrate i try to solve mathematics problems in my mind all recitals alphabet in reverse to relax or close my eyes for a moment and try to just breathe deeply sometimes it works sometimes it doesn't. technology is still quite basic but the game shows what's already possible in the realm of brain computer interfaces perhaps we'll soon be able to control our
4:34 am
electrical devices at home just with our minds. he now has a different goal for years he's been exploring how humans and machines can interact for medical purposes. for example if people with paraplegia could control this robotic exoskeleton with their thoughts they could once again become mobile. but the technology is still in its early stages these are these would have to be very reliable and safe see exoskeleton must stop for example when the patient wants it to as yet it's still difficult to achieve that reliability to become a major global players such as facebook envision a huge market for this technology and a pumping billions into its development why if you could type directly from your brain. instead of typing you could just sink your messages directly into your smartphone facebook wants to make this future vision a reality in just
4:35 am
a few years. a kind of brain controlled typewriter already exists researchers at stanford university have developed a system whereby people can think letters into a computer this enables locked in paralyzed patients to communicate with the outside world. in eat all you need to do is a mandarin moving your right arm for example to the water team on a keyboard and all slide out to the teeth. in addition to that we're also able to turn when you wish to so what about what are you patients can type up to 40 letters a minute but in order to use the technology they have to have an electrode implanted into their brain. they also need an alphabet table to choose the letters with their eyes. this system would not be useful as an everyday tool for people
4:36 am
without such disabilities from your brain. and there's another major problem that stands in the way of widespread use. went into town and people constantly think of other things so they get distracted and you might also be driving a car at that moment or walking the peace processes overlap in the brain without making it almost impossible to pull a text message out of your mind as things stand right now you're also seen scientists from the university of freiburg researching how to separate the various processes going on in the brain tonio balland philip k. meyer use e.g. waves to make these processes visible this shows the difference between moments of high concentration and chaotic everyday situations. here here you can see these classic e.g. alpha waves appear when our test subject just closes his eyes so now i'll shake
4:37 am
your head a bit my business. sort of then be strong waves appear. you know not spend it's a hindrance if we want to get to the actual information that the brain is thinking because this disruption distorts the whole thing and for months you want on. to filter the correct thoughts from the chaos they use a deep learning process in which the computer recognizes brain activity on the basis of e.g. wave patterns that it is already known. to teach the system these patterns test subjects are asked to repeatedly make a movement in this case raising the right arm the computer now learns that the brain wave pattern created represents the desire to move one's right tom regardless of the n.t.'s there is. the scientists have taught this robot how to recognize a specific commands. using only his thoughts the test subject asks the
4:38 am
robot to fetch him a drink. the robot recognizes the specific brain wave pattern and carries out the task. a reason to celebrate perhaps but the scientists are also concerned about the potential implications of their work because it can only function if machines are taught to read neural activity data and this is very risky after all what might happen if corporations like facebook had access to the brain activity data of millions of people. when it comes if huge amounts of brain activity data were stored in one location for the benefit of learning processes it might be that more very relevant information could be gleaned for example eg hoop level one from you could distinguish between gender or ethnic background all things that we don't know
4:39 am
at the moment but it would make sense to think about how to effectively protect this data before simply handing it over and consider whether such systems should even be given to consumers in. the past to brain control devices has already been paved even if they exist mainly in research and development at the moment facebook as well as other companies are in the starting blocks in the race to conquer afterthoughts with technology. the human brain is likely to remain a source of fascination many of its inner workings are still a mystery but scientists have been able to debunk some of the myths surrounding the brain. one involves. a dios mozart who lived from 17. 562-7918 study from the 1990 s. claim that listening to his music could make you smile especially his nose if the 2
4:40 am
pianos in d.c. major. gun it huge public interest and became known as the mozart effect but the results of the study could never be reproduced the mozart effect is a myth. still music that we enjoy can stimulate the brain and have a positive effect on us. one of our viewers in the rock asked about another commonly held misconception concerning the brain. do people really only use 10 percent of their brain. then surely telep a theory or telekinesis would be no problem if people could finally access 100 percent of their brain power. like lucy in the film of the same name. while the rest of us bumble along out of pure falling 10 percent. that's a myth that is more hollywood the reality. using only 10 percent of the organ that
4:41 am
consumes the most energy would be a huge evolutionary disadvantage. even asleep we use far more than a 10th of our brain. no one knows exactly where the persistent 10 percent myth comes from. it's been mis attributed to many people including albert einstein but my heart back to a misunderstanding about the very positive by psychologist william james and his student boris c.d.'s. c.d.'s the son was a child prodigy. at 18 months he reportedly could read a newspaper. later it was claimed that he had an i.q. of 254000000 james then said in a lecture people only meet a fraction of their full mental potential. but he said not. thing about 10 percent or parts of the brain remaining on new just. pop culture has also helped to
4:42 am
perpetuate the myth. of course some areas of the brain may be more active than others but none are completely idle if they can't receive stimuli they'll find another job to do. for example and blind people the visual centers of the brain can adapt to help process or tree signals. but brain cells tend to atrophy if they're the news. quite apart from a conscious decision making the brain has plenty to do filtering impressions regulating breathing controlling reflexes hunger and thirst and much more besides. the fact is only people who suffer real brain damage can no longer use certain parts of their brain. the rest of us can access all of those billions of brain cells. the brain of
4:43 am
a newborn baby possesses many more new runs than that of an adult while in the womb the brain grows that an average rate of $250000.00 neurons per minute. but do not fully do that the brain initially develops many morse an abscess than it actually needs it was hard to comprehend the world and to remember. babies are curious and attentive but come a watch somebody do something remember it and then do it themselves that is imitate a simple action. 6 months old and she's observing closely. you can pull off the toys here and shake it like a rattle. after a brief pause it's layers turn she's clearly noted the trick with the ear. that
4:44 am
shows she's developed some memory for a sequence of events. but that's only one of many stages in the development of memory. psychologists at frankfurt university tested $1000.00 children extensively over a period of 5 years. they wanted to find out what stages children go through until they develop the ability to remember events from their own past and then go on to have an autobiographical memory. the ability to recognize oneself is a prelude to being able to remember things from one's past can morrow recognise herself yet. the task is to wipe away the mark on her face with the help of america is it is it a mark. why don't. morrow touches her face she recognised herself in the mirror not all children can do that one and a half. benjamin tries to wipe the mark off the mirror instead.
4:45 am
because i think now finds the image in the mirror upsetting. look why put away your layers is a bit older. north america way. you'll use recognises himself in the mirror but he's still got a way to go to develop an autobiographical memory. is all to be altered biographical memory is the queen of disciplines within memory and it requires many different components which children don't have when they 1st arrive on the planet. the ability to remember past events is one of those components you leave us recognises himself in the mirror and on screen what's not up there. it's a bit of red tape there where is it. can't you lose connect the past situation he
4:46 am
sees in the video to the present that would be sensational as you would your sister rather young for that now and for what than just what do you see the red thing is kind what is it you can you give it to me. when you take it off the video off grab a fan and listen to the ask doesn't just require him to recognize who's there on the screen the strip of paper was attached to his head a few minutes earlier he also has to understand i existed a few minutes ago and i remember that happening so the paper might still be there only then can you look for it on his own head. by the time therefore most children can complete this task with that they're already much closer to having a full autobiographical memory. remembering an experience is the next stage. tony is 6 and he's shown a scene from 2 years earlier. do we still have this street yeah.
4:47 am
we take those cars and drive them along the streets right now because the situation he also talks about other adventures without any video prompt most of us do you know there was this pull i said to light but didn't get away in time and it went off. to. tell me had to work hard to reach this stage and lest we forget here's the video to prove it. and how good is your memory what did you wear to that party one month ago a red dress or was it the blue one. what did you eat something healthy. for fast food. are you sure maybe you got it wrong. did you have an argument with your friend. well one thing
4:48 am
is clear on them marines are not always as reliable as we'd like. we all have minor lapses of memory from time to time we find ourselves thinking i could have sworn i put the keys on that shelf. after an anxious search we eventually find them. on the desk. or minds play games on us and london based forensic psychologist julia sure says it happens far more often than we realize. again and i like to compare memory to a wiki pedia pe inch you can alter it but so can others and i like the analogy because it describes how flexible our memories are and how they can undergo massive changes in everyday life as well as an extreme situation and explains at what cost of an oncoming car. in experiments sure has brought 70 percent of participants over
4:49 am
the course of 3 interviews to have memories of a crime they never committed. and they remember it in all its complexity as if it really happened. and you know give details emotional details where you think that can't possibly be a force memory and it sounds as if this person really did it all and isn't meant to think you mattered self declared perpetrators and victims can turn out to be nothing of the sort happens time and again. in germany in 2004 a man admitted to chopping up his fiance father and feeding him to dogs he said the victim's family helped him carry out the gruesome deed. but 5 years later the police found the man's car in the danube river and inside they found the corpse of the allegedly butchered would be father in law all in one piece.
4:50 am
here family matter of fact the more you question someone the more their memories can change and that is important for police investigation methods. it means that we have to take into account that repeated. asians can lead to a suspect adding misinformation to their memories about misrepresenting things in a very major way. in australia in 1975 a woman was raped and then gave investigators a very detailed description of her attacker he was soon found and arrested but she had a water tight alibi he was doing a live interview at the time of the rape so if he could not possibly be the rapist why was the woman so sure he was. in this case the answer was quite simple she watched the interview on t.v. just before she was attacked the woman had confused the face she'd seen on t.v.
4:51 am
with that of the rapist. to mention that when people who are involved in the criminal justice system like police officers and lawyers often say that they would recognize a false confession or a false memory when they encountered one once. but that's not true these situations are incredibly difficult to understand for everybody so we can see if someone is lying and we can't see if someone has a false memory that that led to a nightmarish situation for a man in the united states in the 1990 s. while undergoing psychotherapy his adult daughter suddenly came to believe that she had been sexually abused by him for many years she said that had resulted in 2 pregnancies and she had tapped to abort the foetuses with a wire coathanger. but then it emerged that the woman had never been pregnant much
4:52 am
less had any abortions she was in fact still a virgin. judy i sure also consults as an expert on criminal cases and provides training to the police. her primary aim is to teach investigators to. void suggestive questions that can elicit false memories. sure says it can happen very fast. as one being if you think the person you are talking to knew small and even knows more about you in your life than you do then you can soon start thinking yes what if that is what happened on the what if can quickly turn into a. perhaps consume become a yes that is what happened is. false memories can lead to false statements and to terrible miscarriages of justice. incidentally studies show that we are much more likely to notice negative things than positive ones that make
4:53 am
sense from an evolutionary point of view allowing us to recognize problems and dangers and to resolve them but it can also prevent us from shrugging off things that aren't important. however we can retrain ourselves for example by taking time to remember the good things that we are happy about. elephants are known to have a very good memory and those social animals like most primates including humans then there are all social predators that hunt in packs studies suggest the brain can reveal how sociable and lives dolphins for example have been shown to be extremely social animals but other species also appear to be more selfless than we realized. it's well known that parents are pretty small birds but i think also helpful to each other. is an african gray and in laurel park zoo on 10
4:54 am
a river in the camaro the islands she and her friends have been helping the mox plant institute for ornithology with an experiment about social intelligence and cooperativeness. the parents quickly learn that they can exchange a token for food. but in this experiment bella has a problem she can swap her tokens for a treat because the window is closed instead she hands them over to her friend kimmy kimmie then swaps the tokens for food through her window bella gets nothing this generosity without any immediate favor in return surprised even the researchers because until now such behavior had only been observed among some great apes and humans. in the 2nd experiment the parents are given a choice. a blue token means only one of them gets a treat
4:55 am
a white token earns them both a snack they soon work it out and choose white which benefits both birds even though the other one has done nothing to earn a trick. many parents are evidently helpful and not envious. the researchers think this has to do with parent's life number not about. they prefer solidarity to selfishness of. a problem is right why aren't they i'm going to have it do you have a science question that you've always wanted and say it like we're happy to help out send it to us as a video text ovoid smell if we answer it on the show will send you a little surprise as a thank you come on just ask. for more stories about the world of
