to stop the vicious cycle of violence and 3 in residence before it's too late. 30 minutes on dw the what there's to us that's why we listen to their stories. reporter every weekend dw, the we live using our own muscle power. sometimes others give us a behind we also move things all the time and we could soon be getting some help with us more and that's coming on the

kind of and welcome to tomorrow to david dw science. welcome to my teeth as part of a research team working on a wearable structure that assists movement. it's called an ex of skeleton. he's trying it out is limited in size. if you are in a stooped posture for a while though, you'll soon start to feel the strain in your back the excess scalars and makes it easier to maintain that position for longer and for how long does ave that's excess good dasa time. what's the excess skeleton does is absorb some of the mechanical strain from the human body and storm pump as high as investigate supports us and the movements we make every day in various ways. this in the meantime, this some indeed what filled the work and gushing in is part of the european research project focused on exoskeletons for use in small and medium sized companies. the requirements in this context are different from those an industrial

manufacturing your ics. so it's kind of these extra skeletons are earmarked primarily for large companies. for example, in the car industry where the word processes are relatively clearly defined. newtonics and paul for the film kline, we are researching how we can use them, where they're actually needed most time. so in smaller companies, so we're the tasks are more varied for them and the budgets are smaller and that's key. sima, lau and commodities has an avatar, a digital twin, a process known as motion capture, records, all the researchers movements to be out of the door and makes it clear what kind of strain is occurring we're in his body. let's see and do them about time when the extra skeleton is being used. that's what the avatar shows us is that the strain in the inter vertebral disk is significantly reduced. thomas, so the person wearing the suit is a lot more comfortable, but that's not the work,

isn't it? strenuous, because the exoskeleton is taking part of the load. this type of exoskeleton doesn't really strain in the need. however, the less them ending can you missed? there are various types of exoskeletons, and these days a range of companies manufacture them. the basic mechanical design is simple and varies according to the tasks it's where or has to perform. and it's about, you know, it's, it's interesting to see exactly which x is scaled to in a suitable for which activity one's for the. so you have to take various factors into account to the is the material washable, the monthly. yeah. what are the suits, measurements, of course, and then we give the manufacturers are feedback. that's, that's what's the zip codes are gonna be, has to, let's look at the best way to test the suitability of exoskeletons, is to try them out in real work environments. pbs put a rubbish don't, is a powder coating company based in central germany. metal frames for windows doors,

carports, or conservatories, are quoted here and then returned to the manufacturer. as the workers have to repeat the same movements, hundreds of times a day, exhausting work which takes the physical tone and excess skeleton would make it much easier. but it takes some getting used to advance as noise. i'm. so whenever you introduce something new, they'll be some reservations. that's how humans are initially there, skeptical a bit nervous. so we have to help with the adjustment. when is the quick partner for our project partners have investing money and exoskeletons? it's a shame if they just sit in the closet and we don't manage to convince people to use it too, but they don't realize what its benefits are. the plastic afford tied it up on hub and that can take time. where's can't move the way they normally do the suit, forces them to move in a way that's better for their back but doesn't feel very natural

shop or to enough i'm. i've been working all day, but don't have any pain in the lower back and working, but before i'd feel some twinges now and then we'll have some options for most one it's, let's get to sleep. in small companies, workers usually perform a range of task. whatever they're doing, wearing the exoskeleton shouldn't be a hindrance. is this anything what she gave us the ones that might be moving something from a to b? well another as during a forklift. and i may not always have time to take it off, put it on again, and take it off again. at some point, you'll leave it off because you're quicker without it. yeah, the place that i've been to the small exoskeletons will only become part of every day operations. if there's sufficient demand for production, it seems likely there will be ex, though skeletons could also prove helpful in other areas of the chips comprehensive

because they are the fields of clinical care nursing and surgical care. in these areas, it's important that they're safe and then can a patient get a finger caught somewhere, for example, can exit scales and be warned under a uniform? did they adhere to hygiene standards? can they be used in patient care? and these are factors we're addressing in this project and is important because i'm the cause will talk you financially. but in the meantime, allowance, my teeth will have to keep carding. a lot of heavy boxes around the lab of the votes have long been an active tons about weld, same mode, the loan, lean up off to us. that helped to explore space. and before many rolls in manufacturing, some of them can run dodge obstacles. job even does

the thing is don't always go as times this is gummy, it's named, often damaged, putnam cache, and the bavarian town where it was developed. the result is to function as enough and companion for the elderly. so it needs to be able to serve patients a drink rhythm on la luis big hereto from the technical university of munich wants to test how well gummy does carrying hot coffee. the researches have filled the gloss to the brim will go, may be able to serve it without spilling any who can do better, man, or machine to find out, read him on law is going to go off again. it's gone me despite having little experience as of ways so i can try and it's probably better and i managed

to move it without spilling and drop but yeah, let's see how it goes. he gives it his best shot, but still some coffee on the way. it is a big challenge as much as parking liquids. we felt flushing, so you're working late tonight in a different project and having some coffee and then drop the coffee and then start thinking about how we could make the work. and from that on we start putting this into pay for isn't very stormy and going that direction. the problem is programming a robot to do it. many have tried, but so far no researches have succeeded. the may approach this has to be to try to focus on the liquid. so try some other than that mix of the liquid and

this can be very complex and very time consuming. so it can takes minutes hours to compute water to them. and so the liquids and the show work can someone, the once the robot, the feed for hours before it moves of this video showing american teacher he, that swings in different directions like a spherical pendulum, gave the research as an idea for a much simpler approach. because in terms of physics, here's what happens. gravity and the movement of the gloss always act in the direction of the pendulum pivot. all other forces are absorbed by the tray. this means there are no lateral forces acting on the law, so the liquid in it. no transverse forces means nothing, spills of so it's even possible to climb stairs with a gloss filled to the brim. the reset just then applied this basic physical principle to call me wants to explain everybody say this call. it's so

obvious because it is once you understand this is the easiest solution, it's the c plus solution. but dummy still has to prove that it can really do it. the gloss is filled to overflowing. yet he still manages to set it down without spilling a drilled rhythm and has lost but takes it in his straight and and now the test all goes smoothly. even when someone just fills the robot. something that could easily happen when caring for scene is on a daily basis. we once robust of the working close to him on secret for any reason that you are moving quickly, your hands and there are button is to react with the, from the guarantees that would never draft the coffee on you. because if it does then to try so between you and the robot with broken. so safety always comes 1st. and that's why dummy should soon be given more capabilities. as the directv for

directions. these have the robots imbedding with modalities like perception and visual systems. so it can predict and for see the human emotions. so it works even better for us to humans. but the research is still have a ways to go before gummy will be allowed to do all that. when the cats go walk about, they don't usually go that far. i mentioned national, kept track of studies shirts. i mostly stay within 100 maces of my home lions hanging around in areas where pray is plentiful. they territory typically covers an area twice the size of parents had charges all contained with one square kilometer. that's enough for them to eat the film, most animals move and so defined for the food supplying. what about pay with natural edlio from renee sent us this question. why are there

no penguins in the arctic? the north pole is famous for its polar bears one of the largest land predators on earth. they probably loved to snack on penguins, but even though penguins loved the cold, there never found in the icy climes of the arctic the there are nearly 20 different species of pain when all the one live in the southern hemisphere. only the galapagos penguin is found on some of the galapagos islands north of the equator. the remaining species are found in south america, south africa, australia, and new zealand. only a handful of species are actually found and, and article here. the coastal waters provide the best conditions for penguins.

the open sea is their hunting ground, providing a rich supply of food. their preferred dish is cruel, but they also eat and show these crabs. and even octopus, the what the flightless birds rear their young on land. some species build nests from small stones. the others lay their eggs in rocky burrows, arcades like the med delana penguin. the ad for contained with nest directly on the beach digging small hollows in this end. penguins incubate their eggs for one to 2 months depending on the species. so the north pole wouldn't be a suitable environment because it's not solid ground, but it's mostly formed only of ice, which is constantly moving. some species can cope with a mild climate,

but none like it really hot. so the warm water is at the tropics act like a natural barrier, stopping penguins from moving further north. the still, they've occasionally been spotted way up north in recent decades. but scientists believe they didn't swim that far on their own. it's possible they were picked up by fishing boats, reaching as far north as the coast of canada. another possibility is that crews liners took him north. at the southern most point on earth in central antarctica, there are no penguins. the south pole is much too far from the sea. only a few bird species make it that far. like the south color schema, but it can also fly. let us read. why do you have a science question? send it in by a voice message. text. oh video. if we onto it on the shows,

you'll get a little surprise as a thank you. come on just dos for traveling long distances. most of us take a vehicle. it might be a car wreck. so a trump a boat of course we guess on the plane for the environments it's not so good luck to new materials and fields help reduce the impact of planes on how well this going. triple 7 is getting a new skin reflect. film is being glued onto the cross fuselage and engines piece by piece, each measuring one meter by 50 centimeters. that's 950 square meters film for each croft, adding up to a good $1800.00 pieces of fil. a huge task. beginning step forward is here in

groove. the difficult thing is to position the film correctly. also, there are no wrinkles pop as the source of the aircraft. fuselage is curved, so that's the difficult part of the vehicle. that is all, all 12 i've swiss airlines loan hole. boeing, triple 7, across will be equipped with the arrow shock rippling film. the material was developed by newton's attached nik. i'm the chemicals company, p a s f is inspired by shock, skin shock, slide smoothly. we will to, thanks import to the unique scales these demo denture goals of tiny grooves that minimize friction, deliberate film mimics the properties of shock, skin reducing stuff is friction. when the plane is in the the structure on the film is barely visible to the naked eye. on the depth of the group is about the damage of human hair. you can't see it. if you run your finger nail

over it, you hear it. according to the lines calculations, this boom will save nearly $5000.00 tons of canvassing annually. and over 15000 tons of c o 2, that's equivalent to the amount emitted by 87 long whole flights from sea earache to them by the actual fuel savings amount to just one point. one percent. that sounds like a tiny drop in a very knowledge tank. but aviation expert andreas fitness puts it into context. itemized by the time 1 point, one percent doesn't sound like much, but it's a contribution with guides, but we're operating in the system is technically highly developed. and only small steps are possible if i caught the ice. the only big step is sustainable. fuel sto to everything else is small steps being fine tuning and existing system state and esteem creation industry is pinning its height on sustainable fuel either

bio kerosene produced from plant waste oil synthetic fields produced in a chemical process. but as yet, the amount of available alternative fuel is negligible, approximately 100000000 meters were produced last year. on average, the global aviation industry requires more than $1000000000.00 beaches of aviation fuel per day. and sustainable fuel is many times more expensive than fossil kerosene. this intention stuff's synthetic fuel is currently the only way to achieve carbon neutrality by 2050, more or less. but the general public has to be willing to pay for it. because at this stage of production is ramping up, synthetic fuel is significantly more expensive to passengers, airlines, society and government has to do their bit to make it work. new style takes off to stopped. so invest ongoing. swiss will be the well 1st passenger line to synthetic

fuel regularly starting next year, adopting the new across skin technology is what on its way. but the goal of becoming carbon neutral by 2050 is still a long way off. the idea of expanding a radius of movement is not just a modern one. there has been countless inventions throughout history. not all of them have survived into the modern era, but we don't always know why not. historians were curious about one particular ministry power to use the roman empire, so they built a replica to try it out. the lincoln southern germany provided the backdrop for the start of a big day for both builders and scientists from our long and university. last summer, they finally managed to launch a purpose built for ton vessel, the daniel vino, a lot, chris. it's a replica of

a roman patrol boat. they want to study how the river danube was used as a natural border. why did the romans use this kind of boat to patrols or borders? the scientists help to find out by testing about, for historian bogus higher. it was the start of an unusual experiment on the river down you the job of district. we've staked out 40 kilometers stages. does label require everything from the rowers. this is not a light rolling boat for me. it's a 4 ton barge field. it's 40 degrees celsius today, most points. so it will be tough cartoon and volume forest. diana and his team already have previous experience with an older type of ship. in 2018, they built the free to reach yanna alexandria novice or f. a. and the 2 ships were

among those most used by the romans. the tests are a unique opportunity to clear them. this will enable us to understand how the romans were able to defend and monitor their water borders. and today we can actually test these 2 most against each other directly to determine the advantages and disadvantages of each design and what's called to leaking. for centuries, the line nice mark, the outer border of the roman empire. it stretched from scotland and the north across europe to what is today, the middle east and north africa. a line of defense that was more than 5000 kilometers long. our perception of the frontier is mainly shaped by monuments like he drains well in prison. for the upper germanic region line, ease in germany. but today we know that river borders like the rhine and the dining,

we're actually much more important for the roman empire auto autonomy because they were necessary for trade and for exchanging information and the ryan and the danube . were like the free ways of antiquity. the danube frontier is littered with key form or roman settlements. the like regan sport, for example, the style being for past. so the danube line, ease of loan, runs through multiple countries including austria, slovakia, hungry and romania. after the official launch, the tests with the danube, deena alacrity finally got under way for as dryer was confident they would reveal many new insights. give out more time to get tests. we're going to do a number of tests because we assume the roman somehow managed to land on the right bank and not the enemy bank. so that's very important for the danube. and,

you know, we have to somehow figure out what kind of sales they use to do that. the test on best of actions come, the problem is no one knows what kind of sales the romans used on rivers like the danube. in previous experience, researchers have always used rectangular sales. so boris ty, at once to try out triangular or so called routine sales. at the end of the 1st century, the romans still used the mediterranean style about 16 meters long and mainly made of soft wood. like the 1st replica, the group made the f a in this new one, the daniel vina. allat chris is a replica of a river ship from around $358.00. be made of solid oak and 18 meters long for the romans. it was a new type of boat influenced by the sounds and it appears to have been an overnight success. is avoided, was like the volkswagen of ancient military shipping and caught on really quickly.

but we don't know why it's not a single forest. i think the boat was perhaps especially well suited to rivers, perhaps also with the sales another insight that their trip down the down you could give them of the team planned 5 days for the journey. their clothing and equipment was adapted to be as close as possible to what the romans would have used. is this for a long time? we've slowed down to 31 strokes when we've settled in the danube and removing with occurrence. we're moving to shift operations. we're moving 4 kilometers an hour. we've slowed down. the aim here was to measure and compare the speed of the 2 boat designs. and it turned out to be an acid test with tough conditions. without current or even wind. the crews had to fight for every meter of their progress on

the down you. the intense heat made it even more exhausting. almost one week and 200 kilometers later, dias team finally made it to the finish line and paso. but they were forced to leave the s a and behind on route because too many crew members dropped out with all those involved. still consider the journey on the danube, learning these a success to see i'm a kid. so it said that these room and boards for 15 kilometers a part. so that was the distance they patrolled. hey, have my respect sailing down stream. you go with the current from that 15 kilometers upstream is quite a distance on the just the. yeah, i mean it's real continuous. we've now really experienced alignments and appreciate how much harder and therefore greater the achievement of the romans was of course, this was routine for them. the best saving some whole team that between the,

the era of the line nice ended with a collapse of the roman empire. the scientific mission. with the down using a lot, chris ended on reaching power. so now the data has to be analyzed. but 1st, a refreshing break. that's so so this edition of tomorrow today will be back next week, which most sign stories see you then by the

people are fighting over water in the name, the struggle has increasingly fitted herders against farmers. everyone needs this precious resource to survive the day as a new man who wants to mediate these disputes to stop the vicious cycle of violence

and 3 and residents before it's too late. coming on the w to be in good shape pathogens. joe, stand a chance against the human immune system. there are things we can do to help it. what those steps are, and why it's still important to follow the glitch d w the to get the most places in europe are smashing all the records.

stepping to venture just don't lose regret being the treasure map for modern globetrotters. for some of your groups, wykard, breaking, assigned to. and now also in book form. imagine how many portions of a lot of us are now in the world right now. climate change. the story, this is much less the way from just one week. how much was going to really get we still have time to act, ongoing success. subscriber for moving. it's like stopping climate change. that's what they're aiming for. everyone to achieve rethinking in society. some

stuff a give in. yeah, i'm not allowed to give in. we have to divide this a do the best every cast for the for the future. you off all i assume about commitment and hope about visions and the people behind the verb and catastrophe. climate change starts july 13th on dw, the this is, do you got your near within? these are the top stories you create in president would automated polanski has on several high ranking you created and commanders who fought in the siege of mario for the soldiers were taken prison over and russian forces eventually captured the city. they were suppose to remain in.
