we've got some hot tips for your bucket list, the magic corner hot spot for food, and some great culture. laborious to boot w travels off, we go around both part human part machines, high tech hybrids that have long captured our imagination in science fiction and filled. but what about real life? all we on the coast of the brave new world way technology and human biology and all that and more coming up the well chemistry tomorrow to get into the details of your
11:31 pm
perspective. so now a whereas to ground and hold arctic and even experience for since they should have touch again. they 2 miracles of modern engineering. and microchips implanted under the skin can open doors and store past with these high tech advances are a boon to medical technology. good, how far do we really want to go with the merging of human machine? ah, 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?
11:32 pm
just hook up the computer and upload reams of data directly 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 injures base, thomas giblet 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 decision. thomas goods 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. in
11:33 pm
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 centers 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. me. ready ready enough in fibers basically all the machine 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 and oh. busy that's why the interface needed to have as many
11:34 pm
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 signal 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 command they carry can make our muscles move. it also works and the other
11:35 pm
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 v episode in which military researchers sought to develop home. and that could exploit subconscious powers or shut down the perception of pain will not be and it's not just t v, the u. s. army began researching mines zapping military helmets back in 2010 as
11:36 pm
though 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 a whole thing does worry me when going through other scientists and entrepreneurs are getting on board tesla, boss, you on much is also hoping to develop a brain computer interface in 2020 his company neuro 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 tag, the implant tracked activity in the part of the brain connected to the snout. musk believes it's the real deal. everything that's encoded in memory you could,
11:37 pm
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 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. of 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 have to be capable of registering the interactions between a 1000000000 cells with us, 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,
11:38 pm
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. so koby too may have originated in bass, but it probably wasn't transmitted directly to humans. the novel corona virus probably passed through hanging in this or another intermediary host before indexing humans in the wake of the corona virus fears and midst about that have intensified some seem to think of them as flying monsters. but scientists say we
11:39 pm
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 viruses, fatal so many other species baths possess super powers. we human can only dream of 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 gleiss on norman by comparing bat genomes, we have made new findings about how bad are able to cope with viruses or deadly for other creatures. the, for the reason totally sent point does me that could help us to slow down human aging processes and alleviate illnesses for long from conquer this will in
11:40 pm
yet that 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 althea just defined. the atmosphere here in clear, is relaxed. a group is getting ready to go on an excursion with the german environment organisation, not just the balance. place nearby is said to be teeming with the patients fits exciting mans you never really see them apart from fluttering around the sins of their animals steeped in myths and this mutiny of gloves and let me areas from the high. and they only come out at night come home, don't go on. that makes it exciting. don't feel it's still far too light to see
11:41 pm
bats. 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 because if he thought of a lot of people really do believe that they might get infected with radians when about flies and the mucous cut, we have a month that is definitely not true. that is only possible if you get some people believe that when that's why 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 eighty's. 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, hands, together with international research groups,
11:42 pm
almost completely decoded the genetic codes that fix that species. and found evidence of genetic adaptations can, norman, we've examined the genomes for genes which they've acquired during the course of bad evolution audience comes and we found genes that have anti viral functions. and these genes hinder the multiplication of viruses within cells, young indians, and that's not all. scientists have also discovered the genes that unleashed inflammatory responses in the body simply disappears. the researches suspect that these 2 genetic adaptations enabled the bat to control its immune system better. it makes the creek him more resistance 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.
11:43 pm
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 exception of brand spat weighing in at 10 grams condemned to be $41.00. that's quite a nice span. the research is believed, the animal's longevity is linked to the fact that that's the only mammals truly capable of flying through phase code. and the ability to fly means that they can escape from most predators. that cut mortality rate for the fleet avoid. on the other hand, often its ability to fly means that body weight is restricted as the copper could be shrink. if we take the 2 things together, it makes sense from an evolutionary standpoint to take advantage of the longer lifespan. more often bring dealing of alevist apartments and looks and mail, not com, and bad have to remain fit and healthy until an advanced age. to do that
11:44 pm
a little more so to the business of fit 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. what's really kicking off here right above that. i heard it when the fascination of a rustling 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 the most would in new models from this, that would never attack a 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 is no problem. and so by that is the danger of getting rabies from
11:45 pm
a bass in germany. it's very no, that's not a virus fitting months. but animals that we could learn a lot from michelle hiller and his colleagues are planning to unlock more back genome often does 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, adults processor to fall on a dance a long way off the bat isn't going to surrender the secrets to its super powers. last season, a if i was let is read, why do you have a science questions you'd like us to send it in as a video, text or voicemail. if we feature on the shows, you'll get a little surprise from us as a thank you. come on. just does the this please do
11:46 pm
you a question coming from me by the way, brown in period. why did the days go longer and the night shorter in summer time it rotates on it. 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 tend towards the some so much amount to might be with the increases of the us continue to spin. we begin to move out of the sun again and in the darkness. the rotation of the earth on its own axis is what causes day and night. but all planet doesn't merely stand on its own axis. like all the planets and also the system. it also war, but surround us takes a year to complete this elliptical circuit. as it revolves around the sun,
11:47 pm
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 august around the sun. from september, the southern hemisphere tips towards the sun bearing springs. the days begin to grow longer. the closer that a place is to the south pole the shorter the night in some regions stay on top. for some doesn't go down. in the northern hemisphere by contrast to nights get longer because it's tilted away from the sun. but 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
11:48 pm
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 affects our weather. wind rain, thunderstorms, almost all weather conditions occur within the lowest layer of the atmosphere. the troposphere meteorologist tries to give accurate, full cause, so that we can back down the hatches when extremely headed away. but there's another type of where that space, 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 the more
11:49 pm
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 the polar lights that caused by clouds. the electrically charged particles emitted by the sun. this particle stream can confuse gps navigation, disrupt airline communications, and even paralyzed parts of the power grid. it sounds like a catastrophe, straight out of the science fiction film. but so the storms are real. we've just been lucky. the past year. i have been woken up with a phone call from 0 control. they called me at 7 o'clock in the morning, asking me that there has been a big solar event. do we have to have to shut down the traffic in europe? i had 10 minutes to respond to space,
11:50 pm
whether it's caused by the supplies us with warmth and so things life. but sometimes there are supply defects the from our vantage point on us, the sun may seem serene. that things start to look a lot different up close. the sun is a massive fusion reaction fusing hydrogen into helium. this nuclear reaction transforms over 4000000 tons of mass into pure energy. every single 2nd around the clock is the source of space, whether you pick a long time out works at the european space operation center or
11:51 pm
a stock in dumb stats germany. he manages the space where that will fast, which keeps around the clock high on what's happening on the surface of the news data about the sun arrives 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 satellite, the beam, their information to us from space. but what causes space, whether and what effects can it have? let's take the earth will put it here a bit closer to the sun during the reality so that the things are not in, in a perfect scale. but it's easy to see the sun, them, it's a constant stream of charged past the solar winds. the earth is exposed to this
11:52 pm
bombardment of particles from space. fortunately for us, the earth is largely protected from the solar wind by its atmosphere, magnetic fields. but sometimes the solar winds can erupt into a storm we would see a flash that would be the solar last release of electromagnetic energy from the sun . the next thing that we would detect when we measure the environment in space is that they would have energetic particles coming from the sun to blood. and then finally, there would be an injection of enormous cloud of possible from the sun. that would be 1000000000 tons of the matter from the sun itself, dejected into space with the speeds which could exceed 3000 kilometers, but per 2nd. initially. when that happens, the scientists rely on data from satellites. how big is the plasma cloud?
11:53 pm
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 big field of its own. and if this month, the 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. do you mind external, that would impact all the infrastructure that we have on us? high voltage power lines can act 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 damage. transformers causing power outages.
11:54 pm
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 on, globally networked world is even more dependent on modern technology. navigation system, travel, shipping, and satellite 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 disruptions. that slide 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. i
11:55 pm
will also need early warning said that they can move to a protected location on the i s s. before the storm kit. we are improving our preparedness. 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 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 over to and the pump is solar probes plan to venture deeper into the atmosphere and as of before the information the 2 probes garza will help scientists gain a better understanding of the solar corona that might help the solar weather team in dom that's better predicted dangerous solar last and more time to prepare for a solar storm. here on the news,
