all its glitter and glamour is about to continue. watching dw news up next is our covert $900.00 special. don't forget you can find all the latest news were around the world on our website. that's the w dot com there until the berlin. thanks for watching. the news the fight against the corona virus pandemic. how has the rate of infection and in developing? what does the latest research say information and context? corona virus. 19 special next on d. w. many pushed us out in the world right now to climate change because the story was less the waste from just one week.

how much was going to really get we still have time to go. i'm going to subscribe for movies like enjoying a weekend in berlin. discovering the capital of the roman empire, all going for a swim on a spanish island people's hug. so high after the european union agreed upon a digital covered certificate, a travel pass for those who have been fully vaccinated already had covered 19 will have a negative pcr test result allowing travel within the you without the need for more tests. so quarantine almost as if to celebrate and use the operators of the eiffel

tower. one of the biggest tourist attractions in the world announced it will reopen on july 16th. i have been for sewland. denmark is already using covert passports, the system's been a success. so successful, the danish government is hoping to start facing the certificates out in august along with face masks. that's when all danes above the age of 16 of been offered vaccine. he's did use terry schultz. social life is back in full swing in denmark. so yeah, of course we are very happy job and we hope to see the guess the ticket to resuming activities inside or enlarge groups is the corona pass verification that you are fully vaccinated, have in unity jacoby 19 or have tested negative within the last 72 hours, most people use a mobile phone. that is relatively light allowed to resume indoor training in early

may. gym owner, liquor guard hansen has an entry system, worked out. you should be the 1st person that shows ups will check everybody else's passes and they get the shiny little head on. so everybody knows. so today's attention was a place. corona officer and your vaccine. yes. thank you. less than 20 percent of dean's are fully vaccinated. so for most people keeping a corona, pat current require standing in line to be tested every 3 days, maybe half an hour, 40 minutes, and is it worth well worth it? denmark has the highest testing rate in the european union. with half a 1000000 deans getting checked each day about 8 percent of the population. that provides authorities a wealth of information every day and even almost by the hour we know the number of positive test it. people in denmark, we know exactly where, where they tested,

where do late they live. nielson says local municipalities can use the data to quickly intervene in case of an outbreak. but privacy advocates insist the personal information revealed by a corona pass should be strictly limited. the latest version of the up allows almost total anonymity to showing whether or not you're in the clear. kimberly gregson has been working with authorities on this evolution even when, when, when we have such as serious situation in society fighting and they put them in, we shall not, we shouldn't just skip our fundamental fundamental principles about it. they to security and privacy, but some feel constant monitoring should not be necessary to access social activities. they say that's a violation of their personal freedom. if i don't want to get tested just to get in somewhere, when i, when i'm perfectly well, all the sushi is helping organize opposition to the national corona virus strategy

. he views the path as an example of creeping governmental control. why should the state know like every time how often you go to union meeting, how often you go to sport clubs and different patterns of your life? but most days welcome the system as their passport back to liberty. at least one interpret real bar has set up its own testing center to make the wait for that precious green light more bearable with a beer. caterina ok here is an associate professor of law at the university of copenhagen, a good idea eating restrictions. at this point in the pandemic, the one in 5 danes has been fascinated. well i think terry is to be quite honest and it hasn't been an immediate evening of restrictions. so it has been quite gradual to start with. and then basically not as many people in half the size

of the mothers predicted. so there's been quite a lot of pressure from opposition and politicians to actually ease the restriction more quickly. i would say that a big reason that makes the easing potentially, that's problematic is that there's so much testing going on that mark. and you've got these digital passes, tell me about them, what needs to be on them, data wise, and where do we have to be careful because of data protection? sure. and so we're now using the digital passive to basically go to a restaurant, go to the gym even, actually go to a university. and obviously this raises the state of infection, questions like what kind of data has been collected and where it's being stored. and the one issue is that me have the data stored on the person's mobile phone and also who the days that it's been shared with. so we have a very centralized system here in denmark. and so the data is feeding directly. you get a taft and then if your test is positive or negative,

this data is immediately transmitted to your phone and obviously not shared with bodies beyond the health authorities, yourself and which daughter? exactly yes. so it will be the results of your test. and then we all have a personal identification, micah social security number here in denmark, which will be linked to basically whether it positive or negative your name, your address, what part of the country i would say you're living in your age. so all that information is stored in the personnel at data registry that we have here in denmark. is there anything, catarina, or if i can ask you that some governments may like to put on those digital passes that we should say stop, hang on a 2nd. no, that's going to fall. i mean, probably are definitely yes, but i mean, i really think the question is more,

who is it being shared with and for what purposes is it being used? so here in that market really use that, we have a really good idea of who's actually being infected and the level of testing that we have going on. it's so high. so it's 40455 and people are being tested every day here. and the population is 5800000. so it's really helping us to identify is, are the young people or the other, the people who then predict association based on why are so many people getting tests that is a because of the encouragement of this digital pass system that's getting them to line up and get the jap yeah, definitely. so i mean, the testing is really high in here because you need to have a negative test for all these services. and you just can't that they left them with the negative test. and the problem on the flip side is that not, it's not a very high percentage of things that actually makes it here because they chose

enough to use or at johnson and johnson. so they seem defensive and not high. and so as a result, people need to be tested to have me go to a bar. but the success of denmark having is that based on the fact that it's such a small country and has such a great welfare system, i think it's definitely a really important elements and also the level of public trust here. it's also very high compared to a lot of other countries. so i think the same level of questioning has not probably happened here as they would in other countries, maybe like germany. but yes, i mean, funding mentally, all the testing is free here. i'm not so incredibly important and i'm also that there are a lot of test centers all are in the country. so i'm just 20 minutes from 2 different test centers. for example, there are also people in other countries that we're worried that these pastors

could create an inequitable society. yeah, i think it's a really concern. i mean, particularly if, for example, testing isn't free is a very small percentage of the people have been offered. the vaccine, i think here because i think it's free, that's obviously a huge benefit. but on the other hand, i mean i live in the capital. so there's a lot of opportunities to get tested. whereas if you live in western denmark, and in a more rural area, you're going to spend a lot more time actually traveling to a testing center to get to test and discourage people from going to their local bar restaurant. because it's, it's more of a commitment to time which some people do have. but if you have young children, if you have a very busy job, it is just that much more difficult. and of course, that can leads to inequalities, like i will have to wrap it up. katerina ok here. thanks so much for being and i

showed today to get you up close and personal with alpha and correspond derek williams. he's already had one jack. oh, have you been vaccinated yet? he so did you experience any side effects? yes, i got my 1st shot about not 10 days ago, not long after health care if there were these in germany greenlighted my priority group. it was an interesting experience because i admit, i was pretty nervous and my appointment was at one of berlin's big vaccine centers, and there are 6 of them located in various venues around the city. when i went to is at one number, then decommissioned airports where i've done a 1000 times before, but for a completely different reason to catch a flight. i was really kind of shocked. i have to say when i arrived at how

long the lines were, the doctor who gave me my shots said that they were administering for and a half 1000 doses. they are on that day alone. but, but everything actually moved really pretty quickly and efficiently. and i was in and out in less than an hour, i got one of the messenger r n, a vaccines. the only side effect i experienced was, was a little bit a mild pain at the injection side. on my, on my upper arm, i have to admit that i was a little worried about that too, because a lot of friends and family have been vaccinated recently and reactions. we've been pretty evenly split between those who say they feel almost nothing. and those who experienced more hesky side effects like fever and chills, are aching, joints or fatigue. but they say that reactions to messenger r n a vaccines are often worse after the 2nd dose. so, so i'm planning to take

a day or 2 off after i get that in june, hopefully like you know how it goes. me saying it's taking a few days off my 2nd shot. thanks for watching. stay safe, and i'll see you very soon here on the w at the latest next week. have a good weekend. ah, this is the thing to understand the world better. we need to take a closer look the experience knowledge on women who mean

she is the woman here, right? she is a new color is own woman. his meat, the 2030 minutes w. ah. the news every day for us and for our planet ideas to bring you more conservation. how do we make cities, or how can we protect what to do with them all our ways?

we can make a difference by choosing smartness solutions over same set in our ways, the global ideas, mental series on d, w. and on both post human part machines, high tech, hybrid set of long kept it our imagination in science fiction and films. but what about real life? all we on the cost of a brave new world, was acknowledging and human biology merged. all that and more coming up the welcome to tomorrow to day use other states if you want to.

thanks for now. where is to growth and hold our tech and even experience sensation of touch again, they true miracles of modern engineering. and micro tips implanted under the skin can open doors and store passed. the high tech advances are due to medical technology. that how far do we really want to go with the merging of human machine? ah, a lot gets asked of us nowadays educational and career development, lifelong learning. there's no end of knowledge that we have to cram into our brains . wouldn't it be great if we could just transfer all those facts from a hard drive directly into our brain?

just hook up the computer and upload reams of data did into our memory. ah, it's the stuff of science fiction, but might one day become reality? ah, we decided to ask an expert on neuro technology, the brain machine interface thomas good says fryeburg university. in southwestern, germany it sounds exciting and this video here has a realistic look to it. and, and of course it's standards i 5, some of the technology does seem quite realistic when they are decision. thomas steve good is an electrical engineer for more than 20 years. he's been researching medical devices that can be implanted directly into the human body. things like heart pacemakers and cochlear implants, i can help restore hearing. one of his projects is developing electrodes that can be connected to prosthetics and then provide sensory feedback to their wearer. and

ordinary robotic prosthetic allows the where to grasp and manipulate objects. but they can't feel whether they're holding a tangerine or a solid piece of stone. in fryeburg laboratory researchers connected sensors to the prosthetic fingers, the sensors are designed to transmit electrical signals to peripheral nerves and then to the brain. but figuring out exactly which nerve fiber in the arm is the one the sensor should connect to is harder than you might think. ready ah. ready enough in fibers basically all the same a single nerve and your arm has about 10000 fibers and they're responsible for all sorts of things for your fingers, hands for arms, for sensing pain and temperature, just by looking at the fiber. you can tell what it in codes have, i think with the, oh,

that's why the interface needed to have as many contact points to the nerve as possible . in this case, 8 on each side. and then the ultra thin electrode was implanted directly into the nerves, in this case, to nerves in the upper arm with a bit of training this man learned how to sense objects and tell whether he's holding something hard or something soft. so why can electronic components communicate with living nerve cells? it's feasible because many bodily processes are controlled by electrical signals just like in a machine. these electrical impulses are generated by neurons, say in our brain, and then conducted along the neural pathway. when the impulses reach their destination, same are hand, the commands they carry can make are muffled move. it also works in the other

direction. everything we feel see or smell, is coded into electrical impulses and sent to command central in our brain. when we attach electrodes to our scalp, this electrical activity in our brain can even be monitored outside our body in a procedure called an e g. o. but what if this technology was put to a different use, say by the military. what if combat helmets used by soldiers were equipped with sensors design not to measure brain activity, but to manipulate it. that's the premise behind a reason. german tv episode in which military researchers sought to develop home. it's that could exploit subconscious powers or shut down the perception of pain. and it's not just tv. the u. s. army began researching mines zapping military helmets back in 2010. this is the, it's

a real program and it's not being carried out in secret. english. when it's been reported honestly, and researchers in the us have access to a huge budget in with our whole thing does worry me through other scientists and entrepreneurs are getting on board. i will tell my boss on must is also hoping to develop a brain computer interface and in 2020 his company neural link unveiled brain implants called the link said to contain more than 1000 electro channels. the design calls for smart robot to insert the device through an opening in the skull directly into the brain. in this case, the implant tract activity in the part of the brain connected to the snout musket believes it's the real deal. everything that's encoded in memory, you could, you could upload, you could basically store your memories as

a backup and restore the memories you could potentially download them into a new body or into a robot buddy. a future is going to be where, ah, so is this the wave of the future? will we one day be able to download a backup of our brain? many neurologist and researchers scoff at the idea. thomas stieglitz is also a skeptic. ah, that's going to be downloading the entire contents of our brain onto a hard drive. would mean that we need to attention electrodes to the entire brain on both sides. and if they'd have to be capable of registering the interactions between a 1000000000 cells over the, i don't believe that feasible physically or technically me and of course, ideas like this to raise all sorts of ethical questions. everything about me would be accessible to anyone who had my data,

everything from my bank account information to my most secret desires engine willie one day has to choose whether to plug in or opt out of a brain computer interface. not anytime soon, but perhaps we should start thinking about what will happen if science fiction becomes scientific reality. scientists have also got these amazing creatures on the radio. that's one reason, song covey to may have originated in bass, but it probably wasn't transmitted directly to humans. the normal corona virus probably passed through the tangle in or another intermediary host, before insects and humans. in the wake of the corona, virus fears and midst about best have intensified some seem to think of them as flying monsters. but scientists say we have

a lot to learn from these amazing creatures. they glide silently through the night. they can live to an amazingly old age, and they remain unharmed by virus this fatal. so many other species that possess super powers, we humans can only dream of ren if one animal has found the secret to survival. it's the bad researches have long been trying to crack the science behind this secret. now they've made a big step for which that super powers are included in that genes. pushed in for fun can norman device comparing bat genomes. we have made new findings about how bad are able to cope with viruses that are deadly for other creatures. the for the leave of isn't totally send point. that's me. that could help us to slow down human aging processes and alleviate illnesses for long on and

conquered. this will in on yet, that step get a good wraps since long before the corona virus pandemic, they've been regarded as transmitters of dangerous viruses, including rabies, but is all fear just defined. the atmosphere here in clear, is relax. a group is getting ready to go in an excursion with the german environment organisation, not to be back close to a place nearby is said to be teeming with them. since it's exciting minds, you never really see them from fluttering around it since the dea, also there animals speak in miss anderson muted often and mysterious from the high. and they only come out at night. come them, don't go in with us on that makes it exciting. it's still far too light to see

bounce. so patron gets has time to dispel a few prejudices about the mysterious animals. gaps is an expert said that protection for now bu, in central germany, and people often express their fears to her. i'm kind of like the thought of a lot of people really do believe that they might get infected with radio when about flies passing and the movie cut we have a month. that is definitely not true. that is only possible if you get some people believe that when i overhead they lose saliva and that the saliva might drop into their glass when they're sitting in the garden at night and give them rabies. some people have really deep seated fears in the teeth. all these fears justified why a bats able to live with viruses that people find so terrifying at the max planck institute interest. and michelle hiller has, together with international research groups,

almost completely decoded the genetic code of 6 back species. and found evidence of genetic adaptations. norman, we've examined the genomes for genes which they've acquired during the course of that evolution audience comes. and we found genes that have an anti viral functions . and these genes hinder the multiplication of viruses within the cells. young indians. and that's not all. scientists have also discovered the genes that unleashed inflammatory responses in the body simply disappears. the research suspect that these 2 genetic adaptations enabled to control its immune system better, it makes the creature more resistant to pathogens. but that's not the bats, only superpower. they can also become incredibly old. just compare them with other mammals. usually it's the case that heavier animals live longer.

a common dual mouse weighs about 35 grams and can live up to 6 years. an african elephant can weigh 6 tons and live to be 70 years old. and now the section a brand bat, weighing in at 10 grams condemned to be $41.00 question lifespan. the research is believe the animal's longevity is linked to the fact that bats of the only mammals truly capable of flying through phase call it the ability to fly means that they can escape from most predators. that cut mortality rate for us. on the other hand of its ability to fly means its body weight is restricted as the scope of the shrink. if we take the 2 things together, it makes sense from an evolutionary standpoint to take advantage of the longer lifespan to produce more often bring the length of a label on it. so loops, mail, not com, and bad have to remain fit and healthy until an advanced age to do that and

a little more. so to business who are out of it on because on site it's usually only have one baby a year, but that adds up to quite a loss of offspring. over the course of a lifetime. the bat, supporting expedition has reached its destination and the location devices start to go off. really kicking off here right above. i heard it. fascination and a rough and closely intertwined back to the only mammals in germany that still might carry rabies, but how greater risk is that of getting infected? and if you wouldn't be miles from this, that would never attack human, that can bite when you touch them. but that is the only reason that they would do so because they aren't used to it. if you pick them up with a class or a glove, it no problem. tools of either is kind of the danger of getting babies from the

back to germany is very no, that's the, not the virus between monsters. but animals that we could learn a lot from. michelle hiller and his colleagues are planning to unlock more back gina with helping us commander. ultimately, we hope that the findings can be made widely accessible. come up and help to alleviate illnesses like cancer, and slow down aging processes, spots esa. so for long. but that's a long way off yet. the bass isn't going to render the secrets to it's super powers . last easily. if i was let is read, why do you have a science question? you'd like us to stem it in as a video text voicemail. if we featured on the shows, you'll get as little surprise from us as a thank you. come on to start this week.

the question comes from me by the way. brown in nigeria. why does the days go longer and the night shorter in summer autonomy rotate on its own? it takes 24 hours, one day for us to go full circle when we were on the side of the planet, turning towards the sun. we experienced the dawning is today. the closer we tens was to some, some of the key amounts that might increase as the continues to soon, we begin to move out san again and in the darkness. the rotation of the earth on its own axis is what causes day and night but our planet doesn't merely spend on it . so not this like all the planets and also the system. it also all but surround the sun. us takes a year to complete this elliptical ah,

the as it revolves around the sun, the earth is tilted on its axis. that means that the northern and the southern hemisphere is ultimately lean towards the sun during the planet or the surround. from september, the southern hemisphere tips towards the sun bearing spring, the days begin to grow longer. the closer to the place is to the south pole the shorter the night. in some regions be on top that the sun doesn't go down. in the northern hemisphere, by contrast, the nights get longer because it's tilted away from the sun. the further north you are, the last lights you receive in december, the sun doesn't rise a tool in some arctic areas. mm hm. march the

northern hemisphere stopped leaning back towards the sun begins to climb higher and higher in the sky and the days grow longer and longer until the summer after that they start to get shorter. again. i'm just like to start a the changing of the seasons also affects our weather. wind, rain, thunderstorms, almost all weather conditions occur within the lowest layer of the atmosphere. the troposphere meteorologist try to get accurate, full cause. we come back and down the hatches when extreme weather is headed our way. but there's another type of weather base whether we shouldn't take that too lightly over the polar lights, the more than a spectacular light show from the heavens. there are also indicators of space,

whether the more intensely the curtains of light shine and the further towards the equator, they reach. the greater the danger posed by space, whether to our infrastructure here on us. the polar lights that caused by clouds of electrically charged particles emitted by the sun. this particle stream can confuse gps navigation, disrupt airline communication, and even paralyzed parts of the power grid. it sounds like a catastrophe, straight out of a science fiction film. but so the storms are real, we've just been lucky. i had been woken up with a phone call from your control. they called me at 7 o'clock in the morning, asking me that there has been a big solar event. do we have half the shut down the traffic in europe? i had 10 minutes to respond. space is caused by the supplies us with warmth

and sustains knife, but sometimes there is flight effect. the from our vantage point on us, the sun may seem serene. the thing starts to look a lot different up close. the sun is a massive fusion reactor, fusing hydrogen into helium. this nuclear reaction transforms over 4000000 tons of mass into pure energy. 3 single 2nd around the clock fund is the source of space, whether you pick him up works at the european space operation center or

a soak in dumb stance. germany, he manages the space whether office, which keeps round the clock on what's happening on the surface of the news data about the sun arrives here in real time through an online portal. the information is provided by hundreds of ground based telescopes such as this one on the island of 10. every important data also arrives here from about a dozen such a nice beam, their information to us from space. but what causes space, whether and what effects can it have? let's take a look at it here a bit closer to the sun during the reality so that the things are not in a, in a perfect scale. but it's easy to see the sun, them, it's a constant stream of charged particles. the solar wind, the earth is exposed to this bombardment of particles from space.

fortunately for the earth is largely protected from the soda when by its atmosphere, magnetic fields. but sometimes the solar winds can erupt into a storm. we would see a flash. that's what be the solar last release of electromagnetic energy from the sun. the next thing that we would detect when we measure the environments in space is that we would have energetic particles coming from the sun to what's the. and then finally there would be an injection of enormous as possible from the sun. that would be 1000000000 tons of the matter from the sun itself, with dejected into space, with the speeds which exceed 3000 kilometers, but per 2nd. initially. when that happens, the scientists rely on data from satellites. how big is the plasma cloud?

and how fast is it traveling? and is the earth in its path to assess the danger, the scientists need one more crucial piece of information the. so this plasma cloud carries among the big field of its own. and if this magnetic field in the plasma cloud is pointing to the opposite direction, and among the field of the us, then it would trigger a big, a devastating dramatic storm that would impact all the infrastructure that we have on us. high voltage power lines connect like giant antennas. when these high energy particles hit the earth's atmosphere, the magnetic storms can be intense enough to d, stabilize the grid, or even damage. transformers causing power outages.

can 989 a g o magnetic storm triggered a major blackout in canada that left about 6000000 people without power hours. the polar lights were visible from far away as the mediterranean decades later, globally networked world is even more dependent on modern technology. navigation system, travel, shipping, and satellite communications. a solar storm could paralyze these digital systems for hours or even days. and the impact would be dramatic. studies suggests that the global economy could suffer, arose in the last is due to production and supply disruption, the that sleigh. the space where the team is working to raise awareness of the danger, power grids and other critical infrastructure need to be tested and upgraded if necessary. and governments need to make sure that emergency plans are in place

faster. and we'll also need early warning said that they can move to protected location on the i s s. before the storm hits we are improving of badness. that's how i would put it. but the important thing is that things happen very fast. if we detect the big solar event, it indeed hits us within 15 to 17 hours. that's not the time to start to make planning. the plan must exist before that. to help us prepare here on the solar over to and the park has solar probes plan to venture deeper into the atmosphere than as before. the information the 2 probes got that will help scientists gain a better understanding of the solar corona that might help the solar weather team and damage that better predicted dangerous solar flat and give us more time to prepare for a solar storm on us. ah,
