5:15 am
the, it's why he's the one chasing a record, equaling 20th graham france. right, so you're all up. today's the tune for our over 900 special this time with a look at how euro 2020 might be fueling new code, 19 infection across your entire team. thanks for your company. the the fight against the corona virus pandemic. how has the rate of infection in developing? what does the latest research say? information and context? corona virus, not because of 19 special next on d, w. interest in the global economy. our portfolio, e. w business be here's
5:16 am
a closer look at the project. our mission. to analyze the fight for market dominance versus west. ahead with d w business beyond on you to ah, what's the difference that makes football enjoyed like this? like face it's clear. well, the organizers, if you are a 2020 preferred tens of thousands of fans, we'll take the seats at sunday's final in london. but in japan, as a different view to the lympics will take place in empty venues. the crowds have
5:17 am
supported seen as to risk. in both regions. cove at 19 places are rising. one of the european scoring and goal. i'm robots in berlin. welcome to this covey 19 special. the panoramic ment, europe's football fans were made to wait an extra year for your a 2020 to kick off. hence the confusing clash of name and date. but with the continent yet to rid itself of corona virus, the european championships still didn't come without risk. the joy of the euro 2020, summed up by scotland fans, they were euphoric when their team and a point against arch rivals england wimbly tournament came to an end soon after. and there was another sting in the tail, a covert outbreak on and off the pitch midfield, a billy gilmore tested positive, forcing him into quarantine, a post game chatman,
5:18 am
england's ban, chill, well, and mason mount also had to isolate even more worryingly. it was later revealed almost 1300 scottish friends were infectious when they went to london. the world health organization says supporters traveling to games would be a recipe for disaster. how are people getting the other traveling and large crowded convoys of buses? are they taking individual measures when they're doing that? what's happening after the games? when people leave the stadiums, are they going into a crowded balls and pubs to watch the matches? if this mixing is happening among people who are not fully vaccinated, and there is the presence of the virus, there will be cases. the problem isn't restricted to the u. k. financial authorities say at least 300 fans were infected while following their national team . mostly at that 2 matches in st. petersburg that contributed to a sharp rise in cases at home. but despite these connections between nero 2020
5:19 am
uncovered outbreaks, wafer is pressing ahead with hosting over 60000 spectators for the final at wembley . and politicians in several countries are furious at this german interior minister horse, the hoover accusing the governing body of putting profits over public health. i think that you wait for the position is utterly irresponsible up to look for on for themselves. and to put more association should say clearly, we don't want it this way and we're reducing the numbers of spectators. either italy or england will be celebrating a country sporting victoria wimbley on sunday. but without further restrictions in london, fears of a covert hanover will only rise. well, let's speak to dr. hud. sure. he's a former president of the international society aerosol as in medicine. thanks for joining us on the cobra. 1900 special,
5:20 am
a us an advocate of getting football back up and running again during the pandemic . but now we are seeing cases rising in part due to euro 2020. does that mean that torment was a bad idea? i think the tournament was not a bad idea. i think it depends on the instrument and the in the different countries . and we saw the stone arch differences that you mentioned, the english and scottish people, that branch to london govern attractive. but then in england, we have an incident, 7 day incidental for about 300 right now. and the concrete that was much lower. so for example, in germany, we had mentioned as a 5, and we had no outbreaks when the saving unit and the introduction went down and they had to
5:21 am
stay monthly beginning from the beginning. so they started with an incident of 10 and a $2.00 or something that's so we can't say them that football is the real big risk. it really depends on the conditions in the, in the different countries. one match that remains now is the final which is going to be in the u. k, which as you say, has got one of the higher instance races rates in europe. so how risky of the stadium full of 60 plus 1000 people the stadium itself is not a problem. it's the, it's the travel to the stadium as you, as we saw and heard in this other passions is traveling to the stage on the celebration after and the bars and the,
5:22 am
the not in the non, just in the, in the stadium. be the restrooms. so we know that outside we have very little infection, so it's an aerosol infection and that happens most of the time in august. and this can also be a bus or app lane or any of the toilets. and i think the sound of the whisky places. so they sort of peripheral to the actual match itself. suppose you are 20 times an interesting case study because there must have been taking place in different countries. have we seen specific approaches in specific countries that have worked particularly well? i don't think so. i think, i think we saw the differences that are getting the recent we saw the differences in the different countries, but the, the, the interest numbers rates but totally different now. so when you,
5:23 am
when you start with an incident rate, or let's say 200, that means you have 200 people were getting in fact, 580-040-0000 people. so when you're now 50000 people in the industry, you and you would not make any tests, it can happen that you have 100 people which are in fact in the stadium. if you have an incidence of 5, and you're that 20000 people into a stadium, then you have one person understands your rules. maybe in fact, just from the statistic point of view. and, and so that makes a big difference. it makes a big difference. all, any people get the fact that in the, in this country, in this special area where you have to get all these matches happen, outdoor venues, but the lympics would have been different. some of those events would have taken place indoors, but now they're not going to have any spectators have. they taken the right
5:24 am
decision in time. i don't know that it would be in japan, but they are more capital. i think it would be possible in the, in the, in this thing, every now that you have 10000 or 20000 people that are indoors, it's a little bit more difficult. but also it depends on the size of the room and in very large rooms, the arizona cloud is not very concentrated just by the surrounding air and in that way. so it's also that's all risky, but i think it's, it's the right decision when i'd be interested arising and just write an abundance of caution that i don't forget how show it. thanks so much for joining us on the cave in 1900 special ed room. now is the
5:25 am
part of the program where we put one of your questions to ask science correspondent derek williams. oh, lou big scenes require a new boost issue. oh, new really knows the answer to this question. yeah. because the very 1st recipients of vaccines approved for emergency use were only given those shots around a year ago in the course of the initial trials. but it wouldn't come as a surprise if booster shots proved necessary at some point down the line. after all . busy they are, for vaccines aimed at some other diseases. what's clear so far is that most people who receive approved vaccines that they're protected to a great extent for at least 6 months, at least against the current common variance. although the extent of that protection is, of course not fixed,
5:26 am
but varies from vaccine to vaccine and from various to variance. but studies are showing, for instance, that people vaccinated with messenger r m a vaccines that they continue to produce quite high levels of antibodies, half a year after receiving their 2nd doses. and effectiveness levels seem to be holding up quite well at least against older variance of the virus. but a new report from israel's ministry of health has now thrown some doubt on whether the delta variant of stars covey to might be able to do an end run on at least one vaccine. more often than other variance, at least in part because of that new data pfizer and by on tack. now i want to give recipients a 3rd shot of their vaccine after 6 months. which highlights the big, what f, lurking in the background, what if the virus mutates enough to start infecting
5:27 am
a much larger for vaccinated people on a regular basis. and even worse is able to cause severe disease. and that's when we'll really need a tailored booster shot. and, and actually the companies that make koby back scenes are already trialing next generation shops aimed at stopping that scenario if it starts to unfold. mixing and matching different vaccines in the 1st 2 doses could also possibly help provide the kind of broader spectrum immune response necessary to keep even slippery future variance and check. so, in a nutshell, while there's no strong indication yet that our current vaccines won't continue to protect us, maybe even for a long time to come. if new variance start to seriously, in fact large numbers of fully vaccinated people,
5:28 am
then we'll see the rapid rollout of tweet booster shots. me. and that's all for this edition of the coven. 19 special for more about found that makes you head over to the cleavage. $900.00 section of our website the, the we don't to come next time. thanks for watching. take the the out like these can have all german robotics researchers are developing to release drain on the body, neck and shoulders back. how does he ex, though skeleton fair when tested the tomorrow to the w theories,
5:29 am
the little mermaid and split into a reality into a world of fantasy ah, stepped into the palms. christian anderson, a special temperament site in the birthplace of the danish author, is now attracting fans from around the world. in 60 minutes on w. o, the news was right in front of them. they're all for this one moment. then suddenly, we agreed to postpone the are the games that's on your 202021. from off course, during the qualifying round. not least for sports. he rose. it was
5:30 am
a slap in the face, but now we just have to fight there, mobilizing superpowers. i'm fired up and ready, helped down during walk down the go to tokyo, july 19 dw, the me what's this be robot doing in the name of science? mm. and why is this little muscle focused locked by fishermen and researchers? and how can an access get us and make heavy lifting, easy all this on mo, coming up the welcome to tomorrow. today, your science show on d, w. i
5:31 am
x, those skeletons other fields of the, of the animal kingdom. anthropologists among us have the heart external skeletons that protect them from the outside world. vertebrates by contrast, have an endo skeleton inside their bodies. join inspiration from nature. researches have been designing exoskeletons for years. they're often used in medical therapy can also be put to good use for food to keep them on the helmet. schmidt, university, and hamburg profess circle that might not. and his team has spent the past full years testing picks. those credited these supportive structures relieve the strain on the body when bending or lifting on is kind of we don't know of any universal
5:32 am
exist skeleton model that supports several different parts of her body at once. this is instead you have systems like you and that support individual areas in the team as i'm, if they might be into the shoulder region like these 1st 3 or they help the band, like the others. you see here, timothy via the oh, some rigid support made of metal passive models, an active one with an extra motor. how well suited the various systems off the use of the construction site. for example, it's being tested in a special laboratory, doctoral student, she sure. now is putting on a rigid fixer skeleton that she develops herself. it has a motor that is designed to help assist the arms and back when lifting heavy objects. buying mechanics research him schubert places reflective mark is the pacific points that the cameras will record. the markets revealed the position of
5:33 am
each part of the body during movement. the cameras transfer the motion patterns to the computer. additional skin senses record the activity of select muscle grease. the signals are also transferred to the computer. titian young then begins lifting 10 kilogram boxes and moving them from left to right. the conduct this allows us to see how the system would really the strain on a construction worker when lifting or moving heavy object and so on. but we'll also show us whether, who changes the way a person moves just mentioned. if an excess skeleton changes natural movement patterns that could damage the joint time. so what to the measurement show. here, how does the commission by measuring the muscle activity, we see a 25 to 30 percent reduction in the weight being carried during dynamic movements.
5:34 am
this means that the package being lifted effectively weighs 2 and a half to 3 kilograms less. and the optical measurements confirm that the excess skeleton does not impede natural movement sequences. it's a success. next don't, isn't it for a tree that test system for trade people. it's working in partnership with the university equipment is tested in conditions that are as close as possible to real life. this project is all about heating, plumbing, and air conditioning. so the test is being done in a mockup, bathrooms kid, that testing a fabric x, who's got it and designed to support to find it's a passive system. without noticing the back support works by redistributing the strain through the harness. the test subject is strapped into an active support system, which is trolls by
5:35 am
a motor to support the shoulder muscle joint. axis skeleton has a rigid structure that means extra weight and but once which don't complain, air is used to operate pneumatic actuators. these allow the harness to support the shoulder area as needed, but you to, it's important that the phone is, doesn't hinder natural movement. the system is designed especially the job that involve holding a heavy power toll above head high for several hours. in the extra we see that the extra skeleton can dramatically reduce the muscular activity needed for this kind of task. were seen, for example, of 50 to 60 percent reduction in the strain on the shoulder muscles as well. so in effect, we only have to do half the work we would normally do to complete the same task. the research is make sure that the muscles are still doing some of the work and your blank garnished. we don't want the machine to do it all. mostly we want to
5:36 am
use the muscles so that we will remain strong and capable to avoid strain injuries . and muscular skeletal complaints was going to stand. the test phase here is almost complete in the lab. but when we reach the end of the test phase in the laboratory, because we can simulate any more, will go into the workplace. and so we're very close to that because we want find out what will help our end users most in real life. and in some work environment affects skeletons already in regular use. how god's wall is a painter and decorator and uses a passive support system for many jobs. when i'd like to learn today, i'm filling holes and smoothing the ceiling before painting. that means a lot of overhead work which put the strain on my shoulders and arms to his employer invested in this extra skeleton. the system doesn't have a motion, but uses the bodies of energy. when the ohms know it energy flows into the thunder
5:37 am
on the back, which is in charged. when the res 6 funder gets the energy back, i get the sensation of a floating home as if it were buoyant in water. poke, i've been using this system for over a year before the strain of my arms and shoulders was getting back to the test phase. i didn't want to give it back to the company has since kicked it out, 6 teams of painted with the devices, and they all say it makes a real difference. digitalization is transforming society other rapid pace. that's well, it's vital for young people around the world to become familiar with computing. and i said that one day they can help straight to future.
5:38 am
inheriting kids interests at a young age is team has talked a lot above about an invention that's turning computer programming into play. this oversized be, is a big hit at this preschool. it's not toys, but a hi tech tool designed to prepare children for the digital age and introduce them to basic programming skills and classic to me. and i enjoy using it. it challenges the kids and promote logical thinking. liquor instead the i have to plan what to do to the end which command to enter into the be bought to program it, but for korea and it's really challenging a great toy was afforded. so the fun tool was developed and engineered by an
5:39 am
educational research group in switzerland. it includes a roll up game board and the be bought. and the board has target fields such as flowers and honey and obstacles to avoid the children give the be bought a series of commands such as turn right or straight ahead. if they get the programming right, does see the destination, the the for them it's challenging, but not too hard. children in this preschool love playing with the be bought. but how effective is it for teaching young children, basic programming skills professor as best down from the switch federal institute of technology and the civic study. and that question also on board is paid out of my check vendor of the educational lab that created the game. to understand how can i to show like how our main motivation is ensuring equal
5:40 am
opportunities for teaching i t and schools from an early age ensures that all children are given exposure and access came in. so got that. so then since we live, it's live to the family, dennis boys who tend to be enrolled and computer classes and to get the 1st computer your computer course i'm committed and socially disadvantage. children also tend to miss out to have enough punish, kinda around $8000.00 children have already had hands on experience with the be bought playsets. they combined a simple electronic tool, but the board game format already familiar to young children. but what do experts say? can a digital be teach children how to program and what exactly are the basics they're learning here? dr. go, who are those skills include putting things in the right sequence, developing optimization strategies and working towards a goal, sometimes incorporating additional factors. that's what we looked at. her study
5:41 am
confirmed that young children are capable of learning the basics of computer programming. although the bod, his not the be all solution. the why had 2 important hypotheses. first, we wanted to find out whether children learn as much playing on their own as they do when given instructions, and that was not the case. the children need guidance or despite the 2nd hypothesis was that the electronic be bought doesn't always produce better results. some things could be taught better using a regular board game that turned out to be the case. yet we haven't couldn't october. so you don't necessarily need digital tools to teach children digital thinking, but be able to have some advantages, like providing feedback in a playful way. plus schools and preschools in switzerland can borrow them for free, so that the boss will be buzzing around this preschool. again, soon. the
5:42 am
know to this week 0 question. the world has run $20000.00 glaciers. my stuff shrinking. a recent study phone. they've been leaving almost 270000000 tons of a year that now more to now account for about if this authorized and global sea level survey was based on half a 1000000 previously i'm used satellite imitate for think about lumbee. i had a question about, i guess what would happen if all the earth place is melted? one result of human driven climate change is that gracie is around the world melting . in many places where a century ago, there was a thick sheet of ice. now there's only debris, massive areas of reflective surface have been lost. normally the bright surface of the ice reflects the sun's rays back into the atmosphere. but now the earth as more
5:43 am
of the sun's energy which hates the earth's surface. the heat is then released which causes atmosphere at temperatures to rise, which in turn intensifies the greenhouse effect. this continues relatively soon. they will be no glazed is left on the planet. scientists say that all of the 400 remaining lacy is on iceland, for example, could disappear within the next 200 years. in 2019 a memorial plaque was installed on iceland to commemorate the 1st glazier losses to the climate crisis. by one estimate, if all the glass is on a melted sea levels would rise by around 66 meters, areas of land would become uninhabitable. even a smaller, rising sea level would lead to devastating flooding.
5:44 am
rising sea levels is just one problem. out of many, most of the world's fresh water supply is stored in glaciers and estimated 70 percent of it is contained in the antarctic ice sheet might disappear, drinking what would become increasingly scans its global warming continues. climate models showed that within 5000 years, there may be no great is left to anywhere on the if that is read, why do you have a question you'd like us to answer, send it in as a video, text or voice them. if we feature it on the show, you'll get a little surprise from us as a thank you. come on just the eating sign. move fascinating stories from the world of science on our website and on twitter. the
5:45 am
today's places we're hearing the last ice age and the constant, the shifting they mention is dependent on the gradient of the slope, the structure of the ice, the temperature and other factors in the else. in europe, there are thousands of places including the mighty rose lation. it's a magnet for to it, eager to explore its ice grotto. and it's also a huge troll for scientists. researchers on the wrong glacier in the swiss alps are investigating a fascinating phenomenon. how glaciers move and how they slowly but surely slide into valleys below. in other words, the glaciers dynamics an issue of global importance. the blue biology lavonne sisters practice it's relevant globally because practically old glaciers,
5:46 am
including their own pleasure slide. and the biggest eye sheets have large glaciers, where the sliding is incredibly important. let's the way they slide determines whether or not these glaciers move forward that whole battle or remain stable of the scene of if we don't understand how glaciers move, we can make predictions for the future. how the glaciers will behave and weather and now they'll raise sea levels to fight. he didn't made us feel good and staying lost on the glacier bed is drawn down toward the valley by gravity. a little like flowing honey. ringback when the ice flows over the valley floor, it can run into hurdles such as protruding bedrock. oh, when the stress within the ice becomes too great, it sometimes released in abrupt shocks, much like an earthquake. these ice quakes that occur across the surface can be measured with highly sensitive fiber optic cables. they're an important indicator
5:47 am
of glacial motion. gillespie ologist fabi on voter has laid one such cable here. mckeever carver shown visits and this cable allows us to look hundreds of meters down the mountain and we can then measure the tremors that come from within the glacier. it's even copies of measuring the ice quake across the entire breadth of the glacier is critical to understanding its motion. a computer analysis shows all the rumbling going on inside the glacier. ringback doesn't the real time that's coming in now? record seismic vibrations that we measure in the cable. you can carbon lessons in my than what we're most interested in is the glacier bed. that's the center of the glaciers. dynamic sent home. did you know me when?
5:48 am
when a glacier produces a lot of milk dice and has a very weak bed, because water is accumulated there, then it can begin to slide. these light puts at, this sliding process occurs all over the world. enclosures where the bed isn't frozen. that's where the glaciers dynamics come from in dot com because i'm to deny the glaciers motion also depends on the water. inside the glacier. using this portable radar setup, researchers can detect that water. the dynamics are also influenced by meltwater water on the surface of the glacier makes its way inside. through cracks and holes keep progressing. down to the glacier bed, then flows toward the glaciers end or snout. the glacier starts to slide more quickly here because the water acts as a lubricant by reducing friction. alpine glaciers like here at the source of the wrong river flight 200 meters at most each year. by
5:49 am
contrast, the huge ice sheets in greenland move up to 7000 meters a year 35 times faster. but the last, the flow they follow are the same. so the information gleaned in the else can also help scientists better understand the glaciers of greenland animals, and even some have always migrated to foreign ecosystems. the european starving has spread to north america, south africa, and use visa and posing a threat to native species. the asian come to europe and north america, largely due to the exotic pet trade and sport fishing became towed has laid the time all the way to strange. originally introduced to control crop. it's now taking its toll on domestic animals and plants. and in europe,
5:50 am
a tiny moment is causing massive problems. and if you have a tax the depth of lake constance or no home to a creature originally from the black sea. this is it's fascinating and terrifying when they're aggravating and annoying. if we're not really sure what they're doing here, the quantity muscle is disrupting the ecosystem of lake constance, an important source of drinking water and biodiversity coast of booth and echo is a commercial fisherman whose halls have been declining over the years. and his fishing nets are increasingly clogged with clog muscles removed and fish off country. they've got very sharp edges and depend if you're unlucky and dredge up a lot of shells and one catch then the entire net is covered with these tiny hole. so of course that reduces your cash cut,
5:51 am
and the congo muscles are too small to eat the loops and there are no use at all. really. the clunk of muscle was 1st discovered here in 2016, the probably migrated by, latching onto the holes of boats as store ways. ready for the scientists at the institute of lake research and long and hawk and germany, much about the muscles remains a mystery. through close monitoring between 1st want to find out exactly where they're colonizing the lake and how quickly they're spreading. on it. if we're going to a relatively spot now to take samples, water depths of around 180 meters and him on its location where we found clog muscles in the past before the cargo was muscles don't usually live in such deep water is often find an item within now and they seem to be able to survive on the food supply down there and grow in the low temperatures,
5:52 am
they're 2 different temper dependent. suddenly the clouds gather and the wind picks up a change of plans. the boat has to turn back. the researcher is designed to lower the sieve to collect samples and shallower waters. it's dragged along the bottom of the lake like a fled, collecting everything in its path over a distance of 50 meters. ah, meanwhile, is looking in water samples. set off for now, seeing muscle larvae winter to which used to be the case of quicker muscles reproducing even in winter, explains why they've spread and colonized the entire lake so quickly as you can see it here on the all around the lake dens. populations of $500.00 to a 1000 specimens per square meter. this is where the muscle has already taken hold . fission oscar pipes. they're also affecting drinking water supplies because they
5:53 am
clog up the lakes extraction pipes. the concrete walls of the waterworks are covered in clusters of mussels. ah, the facility had to hire for additional people to keep them clean. the for invasion was already a growing problem last year. as an incredible amount. so much more than we used to catch all i see now is quite a muscles. they all have this round belly. meanwhile, they pose a threat to the entire ecosystem. because it's all good to us is a very vague and real concern comes from the fact that there are filter feeders, and they get their food from open water on from feeding, on plankton and if they are too much blank, and there's nothing left over for the other creatures that rely on them,
5:54 am
especially white fish, which are the main catches for the lakes, commercial fishermen. i hope the fish fish might it goes off and my hope is for the muscles to be controlled naturally by a parasite or ease which would level out their number sanford rumble. i live in the us in the delicate balance of nature has been upset. researchers at the university of constance are also hoping the lake can handle itself. biologist, who is on and linda, helped have anchored cages at different temper with i want to use the cage if you compare abundance, muscle inside and outside of katie's to seeds are influence of water burst. muscles. waterfall might help reduce the muscle population in 2002 scientists
5:55 am
using the same experimental setup, found that coots, parents, and push hard dogs that spend the winter at lake constance fed on muscles. they fed unsee pro muscles, which are about the same size as clog muscles, down to a depth of about 7 meters. letting shunt into this winter is an idea for our experiments because we're having a very mild winter. so just a lot of the diving birds from northern europe don't need to come to like constance to feel. the person who came back at the lab in lung and argon tossed advance team is analyzing samples from the morning expedition. the clog muscles are sorted and counted according to size and age. there is a lot of the very smallest muscles here when it's giving the amount of young muscles and watching the level increase. i can't help it worry what it will be like in a few years, piano. the clunk muscle invasion doesn't seem to have reached its peak. the tiny
5:56 am
mollusks will probably continue to play constance for some time to come that's so for today, we'll be back next week with another exciting addition of tomorrow again. until then by by the news. the news, the news. the news.
