d. w. sign show. welcome to to morrow to day. ah, many people enjoy listening to music. good hearing can also mean the difference between life and death, but what happens if our hearing becomes impaired? an explosion or injury caused by caution. earbuds, for example, can damage the ear drum. this problem effects 13000000 people each year and can result in complete hearing loss. current treatment options are less than ideal, something one team of scientists has set out to change injury to the ear drum caused by illness or an accident can result and hearing loss

. many of those affected never make a full recovery. a team of scientists and johnston has been doing research into reconstructing damaged ear drums. and they recently achieved a medical breakthrough. sometimes a defective ear drum can heal, but that wasn't the case with this patient. so he was given an implant, made from his own cartilage these days. it's a standard procedure, isn't customer. can you tip your head back a bit? the problem is that an ear drum made purely of grafted cartilage will never be as good as the real thing. but mostly can alter in existence if we have to use cartilage with a certain thickness and stability of its acquaintance. that has the disadvantage, that the ear drum doesn't vibrate as well as a natural year drama. does this reading this complet refund? and that means that not all sound waves are transmitted to the inner ear with no,

so even after surgery, oh, hearing can be impaired. that's one of the hedges. given that impaired hearing often effects patients, quality of life, marco snyder decided it wasn't good enough. together with his colleagues at the dresden technical university, he's developed an implant that helps restore hearing completely over implant todd, what's different about our implants compared to the current standards of technical implants, is that we've precisely reproduced the natural structure of the ear drum torvard. that's what makes it unique. buffy was on to hide as a medical textiles, researcher dilbert ib. boost task was to find the appropriate material. she established that a protein made of silk warm cocoons was most suitable. she then combined it with a biodegradable plastic thomas her is there also the ear drum has a collage in a stretcher hern to 14 of i am i a protein was

a one component. so we wanted the material used for the e drum to be as similar to that as possible in this matter. the scientists also wanted to replicate the structure of the air drum, as well as the material. the team had to figure out how to develop fibers that are both super thin and robust. oh, marlow iran. yeah. as a ha. normally fibers pulled mechanically and wound on were bobbin, for example vicar, but with spinning fibers that a super thin in the not i, me to rain. so we can't do it mechanically come on as much on, often instead they use electro spinning technology. the process involves spinning the mixture of protein and plastic and to find nano fibers. these filaments are produced under high voltage and are deposited on a collector that replicates the shape of the air drum. oh,

there's it out of your lungs. i'm like this, it slowly turning white, the out. that means the nano fibers coming off the tube is settling on. the collector movers after the collect to all the structure gradually emerges on versus both must be. it's grab this one and this is the result of the spinning processes, a very thin elastic membrane which is robust enough to be used as an implant in front. todd, i'm good for that. no. that's because it resembles the natural ear drum and both material and structure. but does it also have the same vibrational properties? the researchers compared their implant with a natural air drum and a standard cartilage implant. to do this, they got all 3 to vibrate, gene, you chun monitors the results on the computer. this shows the reaction of

a natural air drum. it's very different from the reaction of a conventional cartilage implant which is much more rigid with the new implant. on the other hand vibrates much more effectively mimicking the function of the original ear drum. one to one is ready to cullman fem hung in from the artificial ear drum membrane that we've developed. the successfully transmits the sound energy hog. that means the patient will be able to hear better how best. however, it's likely to be another 5 or 6 years before the dressed and researchers invention can actually be implanted in a patient. oh, we have more than 200 bows and our bodies very incredibly light and yet also very hard. but they can be broken, children and elderly people are particularly at risk. ready after a break,

it's important for the bone to be set back in its original position so that it heals properly. metal plates may be used, screws or a pulse to cost increase, such as have now come up with another idea. it's hard to believe that just 3 months ago marcel spawn crashed his mountain bike, breaking his hand and neck at 1st he didn't know that his life was in danger. luckily for him, there was adopt her in his cycling group who took care of him immediately. then he was diagnosed in a clinic. the us the also the 1st thing they said to me after the x ray was you'd better not move an inch? you have multiple spinal fractures, cushion orthopedic surgeon, re shout, sir, lie operated on spawn. during his follow up examination, he recalls how dangerous the situation was. zane here in blue that you see the bruise here times you see the rupture disks and also at the back of the ligaments

are affected. the risk is if that becomes displaced, then the spinal cord could be injured as well. a month when you look at the pictures and also the story as you tell, and we'll have to say, you've been very lucky harbor. and i had to operate on marcella. bon, twice, 1st from the front of the neck, and then later, a 2nd time on the back to stabilize the spine from their operations like this are impressive demonstrations of what is possible to day in the treatment of spinal fractures. still, i 1st removed the shattered into vertebral disk and replaced it with a placeholder made of metal, a so called cage. he then reinforced the vertebrae with custom made plates screwed into the bones one and we don't want to remove the disk and having compressed because then the nerve endings would be narrowed. instead we want to maintain height. so that's why we put a placeholder in and stabilize it with the flight to plot. then the doped,

his operated on marcel sh bonds, left hand to stabilize the fracture. they pushed to titanium wires into the meta carpal bone of the little finger. this whole titanium implants, minimally invasive spinal surgery. today's high tech medicine has saved marcel sh bond from life in a wheel chair. the small scars have, he'll dwell on, but that's not always the case or skip not to dish all kinds. of course, there are still limitations. i should, for example, they can be implant infections or wound healing disorders, which we still struggle with daily. often i talk that's why scientists are always looking for new therapies to treat fractures even more efficiently, like antonius lent line from the helm, hold center toto. the materials specialist wants to help ensure that in the future,

severe community fractures where whole pieces of bone are missing can grow together better. and he's doing this with the help of a white foam that stimulates the most of new bone tissue inside the fracture. then lines porous foam consists of gelatin and the amino acid lysine. it would fill the gaps between the broken bones, then cells can migrate into it and begin to form new bone tissue. the foam is a place holder for the newly growing bone. wendys of sand or to night when the cells migrate into the gap. so they need an environment that signals that he bone should be formed here, no hunger bit about the process. so we need a guidance structure that the cells can crawl along and which then transmits the by a mechanical information for your machine or should inform out soon, we vomited and placed landlines. foam is supposed to function as a lead compound. indeed, in animal experiments, he and his team have already shown that cells settle in the foam and begin to grow

recognizable here as green and blue dots. the fracture closes as new bone tissue grows. the foam dissolves in the process was not relish. docile. it's obviously something that you work towards for a long time, and then when it works, it's fascinating. urine, because so many different leads had to be realised with his multi functional materially on his yet they are most them. clinical trials on human bone fractures will now show whether this new material is tolerable and superior to conventional therapies. phones in place of metal plates and screws supported by external splints during the healing process. this is still a vision of the feature. in marcella bombs case, his plates will remain in permanently, but he's already very pleased with his treatment was gone on the whole. i think i've been lucky because of his good medical care and senior for zach and becca

mobility is a medical issue that will only grow more important in the future. we won't have, i. does that make sense? why in the next 2 or 3 years we hope before measuring lush, we got calibrated the cameras. the rod is studded with reflectors that can be detected by infrared cameras. they'll record flu, mesquite ada. everything's ready. please walk slowly up to the orange cone and i'll record it with the sensors side of it in all these movement patterns will one day serve as a source of interest of medications and therapy, or to monitor the course of a disease. for example, whether someone walks unevenly above what we call gate variability and locus of or someone lamps to possibly spare their joy on a delinkum. ok, that's extremely important with osteoarthritis or if someone's had a bone fracture,

exclaimed british shopping in the scientists have already succeeded in capturing a person's patience or test subjects like class planner for days on end during their daily lives. in p v, a giant. we know that it has a significant influence on neural or brain function, and you feel better to express a sock every run, assess, so endorphins, you feel happier when you do something. that's why i was very happy to take part of the say, again, the media mot. melinda. when so not a layman's anchor and louse, she began to examine the data. the sensor has collected over the course of a week, or it has recorded movement and all 3 spatial axes and save the motion curves into fi, important information in it. among other things about the pace, quantity, variation, length and symmetry of the strain pattern, patient walked cycled or climb stairs during the day. all of that is dr. liddy,

are also recorded. i don't see an international consortium. it's conducting research as part of the pioneering mobilized di project. ching society where business men traditionally, we know that people who walk faster than one point to manage to keep their distance from him or not walk any slower and the reaper comes closer and closer are becoming a growing problem in 2019 over a 1000000 people died worldwide from infections that couldn't be treated. studies show it's a huge problem. certain viruses can help fight bacteria, so called bacteria phases have been used in georgia for the past 100 years. but there are no reliable studies to show whether they're truly safe with antibiotic resistance on the rise. intensive research into phases is now underway around the world. this is what an alternative to antibiotics looks like.

bacterial faces. they're highly specialized viruses and the natural enemy of bacteria. that's why neurologist thomas kessler has been interested in phases for a long time. the goals fall died from the big advantage of by tyria pledges, is that they can be used to target specific strains of bacteria. the way they kill these targeted bacteria is just like a key that fits in a keyhole long. sit foxy on loosely austin 1st law bacterial say just only target certain bacteria. the phage docs itself on to the cell wall of the bacteria and then injects them with its genetic material that causes the bacteria to replicate new features. the new fe just caused the bacteria to produce an enzyme which dissolves the cell walls of the bacteria. the bacteria then destroys itself.

the phage is that a released can infect other bacteria. the special thing about the phases is that each one is only effective on specific strains of bacteria, o tbilisi, the capital of georgia. there's a place here where phases have been used to battle bacteria for decades. here at the other institute, patients come every day to get bacterial ages to fight infections of the bladder or wounds. that won't heal. we are good at 1st. they take a swab. the bacteria are then cultivated in a petri dish to identify the germs causing the infection. the bacteria, if ages the institutes precious treasure, or captain refrigerators, each type is tested for which bacteria they kill him. these stages formed the basis

of the production of our medicine that we sell in a standardized fashion. usually it's a mixture of different phases in fog that way we raise the level of effectiveness with a simple test on the cultivated bacteria shows which page cocktail is most effective and fighting the patients infection. fades therapy is part of george's basic health care system. the institute has developed several standard fates, cocktails, you can get them in any pharmacy. and the pages also have another great advantage to building every shogun gospel, unlike antibiotics, ages only destroy the bad bacteria in the organism. bacteria useful bacteria aren't affected salient. antibiotics kill both the bad and the good bacteria about dealing . that's the clear advantage of phage is shanpa. she pockets back

to switzerland and thomas kessler. he's been keeping tabs on developments in georgia for a long time with great interest. he has been de tbilisi, where he conducted a study on urinary tract infections for the 1st time, thomas kessler also used such failures here in switzerland, in an experimental trial. namely, with jacqueline mer, camper, balsam blair will, you know, on 5 consecutive days, the phasers were flushed into her bladder via a catheter. so then if you style kids have been gone during those 5 days, the entire feeling in my body changed. it was them and soon i was out of the infection mode. mom picked up, you know, the period where the body is only fighting off illness. on thursdays, it was a wonderful feeling that finally things would be different on the scene shows on the halter. no 100 bucks, but in spite of the pages, the infection returned. tip on me going to fools as we're assuming that the

bacteria of ages were not able to kill off all the bag material that were present. so other bacteria were able to keep on growing. and the symptoms came back, all isn't told me, the toll causing to stop that from happening again. thomas kessler is working with micro biologist at martine listener to make the failures even stronger. the phasers will be engineered in the lab so that their effective against a broader range of bacteria soon the data into ist us. the idea behind it is that we modify the bacteria, thaddeus, so that they can attack and kill the problem germs effectively. and through additional information, they can even eliminate and neutralize other bacteria that are often present in these infections. ily mean, even when natalie is young, couldn't. the genetically modified vegas should also stimulate the bodies own immune defensive. maybe the pages are currently being developed in the laboratory.

the 1st test on humans are scheduled to start at the end of the year on blackboard . vince is cling with if we succeed, so lizzy bacterial, phase therapy. it will be a revolution of not only in the treatment of urinary tract infections, but also in the treatment of other infections that i caused by bacteria. one of especially in the context of multi resistance, but shown you mohammed foot moore, the physician, and the kind the researchers hope to have conclusive results in about 5 years. if our blood is read, why i gave you a now over to you, do you have a science question? send it to us as a video, text or voice message. if we answer it on air, we'll send you a little surprise as a thank you. come on, just ask and don't forget to check out our website. oh, look us up on twitter. and now to this week's question from rodrigo,

mankato in ecuador does water drain in opposite directions in the northern and southern hemispheres. it's certainly the case with tornadoes and hurricanes. the massive air vortices rotate in one direction in the north, and the opposite direction in the south. this is due to what's known as the cory. all this force our planet is constantly rotating. everything on its surface is moving to, but at different rates. it's like a ferris wheel. sitting in a gondola far away from the central axis. you would move faster than someone sitting at the wheel center. equally, some, one of the earth's poles is effectively spinning on the spot. this variation and speed also affects the oceans that cover our earth and the atmosphere that surrounds them. and as a result,

winds blowing from the equator in a northerly direction are deflected eastwards, while winds blowing to the south flow in the opposite direction. this means the air flows and the 2 hemispheres of our planet effectively mirror each other. the corey, all his effect means typhoons and hurricanes, always turn in the same direction in the northern hemisphere, they rotate counterclockwise. while in the south, they turn clockwise hurricanes can be up to 2000 kilometers in size. the flow of water in our bath tub is tiny by comparison, too small to be affected by the korea's force. here. other factors come into play. how symmetrical is the bath tub? how does the water move once the tap has been turned off and in which direction is the plunk pulled out?

it's these more random factors that caused the water to drain and varying directions. and they apply equally and both in north and the south. that's all for this week. thanks for joining us on tomorrow to day. see you next time with ah ah, with
