he was showing it was an incredible feeling that people were liberated to for more security, more freedom, more dignity of their hoax. mental filled me where does the stand today? 10 years after the arabs spring and rebellion starts june 7th on d. w. both pod human pallets machines, high tech hybrids that have long captured 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 of detailed data per 2nd. so now day whereas to grow and whole dot text and even experience the sensation of touch. again, they true miracles of modern engineering. microchips implanted under the skin can open doors and store pulse with these high tech advances are due to medical technology. but how far do we really want to go with the merging of human machine? with a lot gets asked of us nowadays educational and career development, lifelong learning. there's no end of knowledge that we have to cram 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 directly into our memory. ah, it's the stuff a science fiction, but might one day become reality? ah, we decided to ask an expert on neuro technology, the brain machine interface. thomas giblet says fryeburg university in southwestern, germany. ah, it sounds exciting and this video here has a realistic look to it. and, and of course it's standard size 5. some of the technology does seem quite realistic. thomas stieglitz 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

that 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. in 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 the 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 nor fiber in the arm is the one the sensor should connect to. it's harder than you might think. ready ah enough 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, a 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 reached their destination, save our hand, the commands they carry can make our muscles move. it also works and 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 t episode in which military researchers sought to develop home. and that could exploit subconscious powers or shut down the perception of pain,

nothing v and it's not just t v, the u. s. army began researching mines, zapping military helmets. back in 2010. this is do. 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 god. the whole thing does worry me. it doesn't go through other scientists and entrepreneurs are getting on board. because my boss, you must, is also hoping to develop a brain computer interface. and in 2020, his company neural link unveiled a 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 pig, 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. if you could potentially download them into a new body or into a robot body, the future is going to be where 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 go home by 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 they'd have to be capable of registering the interactions between a 1000000000 cells call, but i don't believe that feasible physically or technically me and of

course, ideas like this. so raise all sorts of ethical questions, which 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 have 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, sounds covey to may have originated in baths, but it probably wasn't transmitted directly to humans. the novel corona virus probably passed through penguins or another intermediary host before in fixing

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 to say we have a lot to learn from these amazing creatures the vaguely, silently through the night. they can live to an amazingly old age, and they remain unharmed by viruses, fatal so many other species. baths possess super palace. we humans can only dream of when if one animal has found the secret to survival, it's the back. 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 lies fun, get norman by 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 reason totally and point does that can help us to slow down human aging processes and alleviate illnesses who for long and conquered, this will in them yet still 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 justified. the atmosphere here in clear, is relax. a group is getting ready to go on an excursion with the german environment organisation, not just the bat, close place nearby is said to be teeming with them. since it's exciting minds, you never really see them apart from fluttering around since the dea, also their animals steep in myth, anderson, mucus of lawns and lemons areas from the high. and they only come out at night.

come them don't. going to goes on that makes it exciting. don't feel it's still far too light to see bat. so patron got has time to dispel a few prejudices about the mysterious animals. gaps is an expert for that protection for now. bu, in central germany and people often express their fears to her i'm kind of tough at the thought of a lot of people really do believe that they might get infected with radians when about flies passing new movies. we have this 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, teeth, all these fears justified. why a bats able to live with viruses that people find so terrifying at the max tank

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. beacon norman, i will examine 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 a 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 is suspect that these 2 genetic adaptations enable the bat 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 with 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 perception a brand that weighing in at 10 grams condemned to be $41.00. that's quite a nice spend. the research is, believe the animals longevity is linked to the fact that the balance of the only mammals truly capable of flying fluke phase, call it the ability to fly means that they can escape from most predators. although that cut mortality rate for us on the other hand of its ability to fly means that body weight is restricted, as the copper could be shrink as if we take the 2 things together. it makes sense from an evolutionary standpoint to take advantage of the longer lifespan. more

often bring delaying over labor respondents and looks and mail, not com and bad have to remain fit and healthy until an advanced age to do that and a little more. so 2 bits and out of fit on cars 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 sporting expedition has reached its destination and the location devices start to go off with really kicking off here right above i heard it. fascination and a rough from place the intertwined bat. so the only mammals in germany that still might carry rabies, but how greater risk is that of getting infected? and if you come up with a new mas conveys, 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 clause or a glove,

it's no problem. so by that is kind of the danger of guessing rabies from a back in germany is very low. that's the, not the virus thing month does. but animals that we could learn a lot from michelle hiller and his colleagues are planning to unlock more back gina with helping us command. if 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 lunch. but that's a long way off yet. the bass isn't going to render the secrets to its super powers . ah, if i was little read, why do you have a science question? you'd like us to send it in as the video text or voicemail. if we featured on the

show, you'll get a little surprise from us as a thank you. come on. just does this please? the question comes from the way brown in nigeria. why did the days go longer and the night shorter summer autonomy rotates 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 of the day. the closer we turned towards the amounts it's might you ever see increases? the earth continues to spin, we begin to move also the song again and in the darkness the rotation of the earth on its own axis is what causes day and night. ah, that's our planet. doesn't merely spend on its own axis,

like all the planets and also the system. it's also all but surround to us takes a year to complete this elliptical circuit. ah. so as it revolves around the sun, the earth is tilted on its axis. that means that the northern and southern hemisphere is ultimately lean towards the sun during the planet august around the sun. from september, the southern hemisphere tips towards the sun bearing springs. the days begin to grow longer. the closer the place is to the south pole, the shorter the noise in some regions be on top set down in the northern hemisphere by contrast to night get longer because it tilted away from the sun. the further north you are, the last lights you receive. in december, the 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. and i the changing of the seasons also the 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, so that we can back down the hatches when extreme weather is headed. our way, but there is another type of weather space whether we shouldn't take that too likely 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 greatest danger posed by space. whether to our infrastructure here on the polar nights caused by clouds of electrically charged particles emitted by the sun. this particles stream confused 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. the past year i had been woken up with a phone call from europe control. they called me at 7 o'clock in the morning,

asking me that there has been a big solar yvette do. we have half the shut down the traffic in europe. i have 10 minutes to respond. space. weather is caused by the supply us with warmth and sustain life. but sometimes there are side effect the from our vantage point on us, the sun may seem serene. the things start to look a lot different up close. the sun is a massive fusion, react fusing hydrogen into helium. this nuclear reaction transforms over 4000000 tons of mass into pure and then every single 2nd around the clock fund is the source of space. whether

you pick her long term out works at the european space operation center or east oak . in dumb stance. germany, he manages the space whether office, which keeps around the clock high on what's happening on the surface of the me. 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 reef. important data also arrives here from about a dozen satellites, the beam, their information to us from space. but what caused this space, whether and what effects can it have? let's take a look, put 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 limits a constant stream of charged particles. the solar wind, the us is exposed to this bombardment of particles from space. fortunately for the earth is largely protected from the soda when by its atmosphere and magnetic fields. sometimes the solar wind can erupt into a storm we would see a flash that would be the soul of flask release, of electromagnetic energy from the sun. the next thing that we would detect when we measure the environment in space is that we would have energetic particles coming from the sun to what's the earth. and then finally, there would be an objection of enormous cloud was possible from the sun that would be 1000000000 tons of the matter from the sun itself as if with dejected into space, with the speeds which could exceed 3000 kilometers, but per 2nd. initially,

when that happens, the scientists rely on data from satellite. 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. ah, so this plasma cloud carries among the field of its own. and if this magnetic field in the plasma cloud is pointing to the opposite direction among the field of the us, then it would trigger a big a devastating to your mind extolled 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 atmosphere, the magnetic storms can be intense enough to d, stabilize the grid,

or even transformers closing power outage in the 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, well, there's even more dependent on modern technology, navigation systems, travel, shipping, and stuff like communications. a solar storm could harmonize these digital systems for hours or even days and the impact would be dramatic. studies suggests that the global economy could suffer billions of euros in last is due to production and supply disruption. that's why the space where the team is working to raise awareness of the danger. how grades and other critical infrastructure need to be

tested and upgraded if necessary. and governments need to make sure that emergency plans are in place. the astronaut will also need early warning that they can move to a protected location on the i s s. before the storm. 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 hit the earth 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 and the pocket solar probes plan to venture deeper into the atmosphere than ever before. the information, the to pros got that will help scientists gain a better understanding of the solar corona that might help the solar weather team

and that better predict how dangerous, so le flat and give us more time to prepare for us. so let's storms here on us because you can find more fascinating stories from the world of science on our website and on twitter battle for today. we'll be back next week with another edition of tomorrow today. until then by, by the the me the news. the news.
