they see a suspect with a knife stick shouted. and that's all for now a carbon special program is up next don't forget you can always stay up to date with all the latest headlines on our website to be thought of dot com you can also follow us on twitter and instagram as well the handle you need is active d.w. news i'm anthony have more headlines coming up in 45 minutes to. the fight against the coronavirus pandemic. has the rate of infection been developing what does the latest research say. information and context the coronavirus update 19 special. on t w. o guys this is the 77 percent is the platform for the suits against these issues right.

you know all of this. great. young people to be have the solutions to your job. 77 percent now. on t.w. . going to school every morning spending your day together with other kids in classrooms none of this can be taken for granted anymore education in times of the pandemic our topic today. welcome to or 900 special on this good friday a public holiday in many parts of wells but soon the struggle starts again trying to keep up with the curriculum despite lockdown. every morning the via royal family

has to decide which of their 4 children gets to do online schooling that day the family in the believing capital of hamas only has one smartphone just like many other families in the country. but then there are also problems with the internet connection. there are so many different apps classroom soon and so on. and most of them only work with the high end phone and decent internet when i go to work at 10 am there is only one suitable phone left here and so 3 children are left with nothing. like the platform for virtual school lessons was set up by the bolivian education ministry the government insists the system has been set up in a way that ensures everyone can access the online classes. we

set up a timetable that regulates who can use the platform when each day is allocated for a different school so it's not like all the children have to use it every day. but obviously the system still needs further optimization. yes you. are using the school platform is free of charge but access to me internet is very expensive in bolivia a problem that christiane they own has long been urging the government to address. he set up an advocacy group to draw attention to the problem. to believe you only got fiberoptic internet in 2018. network does down cover most of the country but almost households are still are not connected to it all. believe he is dashing

telecommunications. bernie states that one gigabyte of data costs $5.00 a price not every family can afford going to morrow. so let me repeat of only those with more money to report internet access even so education is no longer free in bolivia because right now the more money you have the morning to murren being may have been good math the education ministry has promised to provide $30000.00 computers to at least to prove the hardware problem but that won't be enough for all many families like the vo as will have to continue finding their own solutions to ensure their children can take part in online schooling until the vaccine rolled out advances enough for children to return to the classroom. yet should schools remain open or should they be closed to stop the spread of the virus let's bring in jonathan silk principle expert in

a merchant he preparedness at the european center for disease prevention and control in stockholm good to have you with us and i know that you conducted a study and to covert 900 schools. when it comes to keeping schools open or not what are your findings thank you very much for having us 1st of all we're constantly updating the literature on revealing other studies on this we're finding that of course like any what we call nonpartizan tical interventions if you close something in society that leads to less social mixing so will have an impact on the overall transmission so that's a potentially important measure of what we're seeing and what the most recent literature shows is. on the 2nd wave and more recent closures of schools have less of an impact than they did in the 1st wave and this has to do with. schools have adopted in the way that they've been practicing their not operate in this they didn't prepare the. locals but they're doing more measures internal the. safe to

keep students safe to try to keep teachers there and those measures have an impact and so we think it's it may be necessary to close schools there's no question about that with the new parents circle it in but the general concessions that show you in the. relates to trying to keep schools open and close in the money as a last resort i mean would you 1st of all were could you define that last i mean who will watch determines what to this last resort would be that has to be decision makers in the local context to understand the transmission levels understand the burden on the health care system of the current levels of i.c.u. and so on and to really do a proper assessment of what measures are placed in schools if everything has been tried within the schools to really keep transmission down or not and then what sorts of levels of schools that's also not make it a binary thing schools do not need to be just for the open or for the close the hybrid models there are different age groups that are important to consider so it's

not just a whole either or situation and it is either there are lots of options there for with or if you make as doesn't necessarily make it more easy to to them to the right conclusion. do we actually know where children catch the virus in the 1st place is that happening at school do they get from teachers from all the children or do they bring the virus into the school because they catch it at home. that's a fantastic question and we've been trying to understand that better in terms of the school settings themselves so what we've actually found is that there are very few documented instances where you see large braves' in school settings so transitions certainly happens in schools but the literature from many different countries in europe and global it's just that there's not necessarily the need for lots of the breaks and in school settings what we wonder and what we need to know the more about of course are what happens to children not just in the school itself but after school extracurricular activities on the way to school on the way home

from school and of course as you mentioned in household settings there's also the possibility for transformation so we don't have precise numbers on that but the information on the schools is that they can actually be operated safely without too many instances of large operators i mean this is the still quite trying a very confusing time so a lot of parents feel safer having their kids around and some in some countries reopen decided to not send to their kids back to school because they don't trust the situation do they have a point. it's really hard to assess that without knowing the specific details of the context in which they have made those decisions like for certainly understand why people are worried there's a lot of research also from from germany a large study just from scotland recently that shows at least for the parents of younger children there does not appear to be an increased risk to the parents catching the virus from their children even our parents when they've been some back to school we also know that by and large the number of severe outcomes in children

is very very low we're we're not seen any change in that even with the new variants we've been following very closely into millions of cases and children particularly younger children follow the same age graded so we know how it will be continued to be the most risk all the. older adults but children really have very very rare instances of severe outcomes such as possible is that. right but we do know that children can carry that and they can spread the virus so what do you make of the concept of home schooling wouldn't act in this moment in time make most sense. you know it's true that care children can and can transmit the virus and as i mentioned it appears to be the case that they transmit it somewhat less than an adults do and they are also to be less susceptible to the virus than the novels do i am i by no means an expert in education and homeschooling but what we wonder

stood from the vast amount of literature that exists that it is very difficult for children to to be home and we understand as well that there is a gradient so those so learning loss from children is less in children from well off backgrounds but from deprived backgrounds vulnerable backgrounds this can be really detrimental submitted to the education and even the health and wellbeing of children so all these things have to be taken into account there is no easy answer for the patient up of but these are the things that decision makers do need to consider indeed a lot of food for thought there for decision makers join us and from the european center for disease prevention and control in stockholm thank you so much for your time as he steps thank you very much thank you well and time for your questions now over to derek. how long can vaccine side effects last conforte indicate it's working. i want to leave all the

speculation about blood clotting and the astra zeneca vaccine behind for a minute and focus on what we know for certain about common minor side the facts reported in connection with covert vaccines pretty much all of the ones approved so far in various parts of the world appear to be pretty react to genic which means they regularly cause mild side effects like like pain and swelling at the injection side as well as things like like fatigue headache fever chills or aching joints the single shot johnson and johnson back seen appears to cause those effects somewhat less often in 2 dose m.r.i. they back scenes they seem to occur more commonly after the 2nd dose while the opposite seems to hold true for the astra zeneca vaccine. another point worth

mentioning is that younger people seem to react more often and more powerfully than the elderly it's thought that's because they have more responsive immune systems authorities say the symptoms can last a few days but but in most of the firsthand reports that i read they subsided within 36 hours the good news is that side effects while unpleasant are actually a sign that the vaccine is the doing what it's supposed to do which is laying the groundwork for an immune response so that if you are infected with the by wrists your body can get to work straight away wiping it out personally and more than happy to experience a day or 2 of discomfort if i know that i'll be protected afterwards from a potentially life threatening case of covert 19 that sounds like

a really great deal to me. and finally a shopping malls are closed amid not condemning lockdowns a school in the u.s. state of vermont to decided to make use of the empty space students can now take lessons in this from a macy's mall why not well that's all for now thanks for watching. this quest is it 6. to understand the world better we need to take a closer to. fix. the budget. cuts. that.

in the end i say oh what is it and exactly one year ago i was here standing on this way on the singing thing i'm playing my morning with the musicians on the bottom lyceum orchestra how are musicians in cuba coping with the coronavirus crisis one year after their joint project mozart 1000000 mom. march 20th. 30 minutes. more than a 1000 years ago europe witnesses a huge construction boom. kris jenner be firmly established itself. both religious and secular leaders or to display their power.

to trace the games. including the tallest biggest and the most. structure. is how massive churches are created. conscious. starts. on w. . it's fascinating how different people. but research doesn't always reflect on diversity. today we look at how we can all benefit from factoring in things like to end. this coming up. welcome to tomorrow today the science show on t.w. . every $100.00 researchers in the natural sciences

worldwide on average only $28.00 of them are women. the ratio of men to women is almost 5050 and many latin american countries russia and in eastern europe. but western europe and the united states lag far behind. yet as the examples in our reports show women's perspectives are essential to research. this is a female turtle and this one probably to the overwhelming majority of newborn sea turtles in the great barrier reef a female posing a threat to the future of the colonies that. a development only discovered when research is specifically tracked to male and female populations. so gender disparity also extends underwater sure and not just they're. doing

research wrong and cost lives and money. london she being a has spent 4 decades exploring. and in home saying the fundamental bases of research. dependable study she reveals those that take in fact is relating to sex gender and intersectionality from the outset. but what does that mean an individual's biological sex is determined by physical characteristics except chromosomes hormones and reproductive organs do not always conform to conventional binary categories which is why biologists now talk of the male female spectrum. the cultural sex or gender refers to socially constructed roles patterns of behavior and identities and they don't necessarily correlate with the biological sex intersectionality refers to the often blurred boundaries between various elements that play a role in our lives everything from disability to ethnicity sexuality class and age

so why is it important for research to include factors like sex and gender. if we don't consider the gender aspect we're going to miss the opportunity for discovery for making something more exciting and also the companies won't be able to sell their products very well because they won't work for many many people and that can have dangerous consequences. in medicine recently the us withdrew 10 drugs from the market because of life threatening. and 8 of these had worse effects for women not only does developing these drugs cost billions of dollars but when they fail they cause human death and suffering we really can't afford to get the research wrong and there are further examples but it's been known for some time that women have an almost 50 percent higher risk of suffering serious

injuries in a car crash than men. the primary reason is that crash test dummies a modeled on. standard sized men people with different physical dimensions pregnant women the overweight 10 fragile older people are not represented in standard tests . but inclusive research also has benefits for men osteoporosis was traditionally seen as a woman's disease i delay in diagnosis and treatment can compromise a patient's quality of life but men make up a 3rd of those patients who subsequently suffer a broken hip and their mortality rate is higher. unconscious bias is also embedded in so-called cutting edge technology. we found out that facial recognition doesn't work for women and it doesn't work for people with darker skin so this researcher in facial recognition is a black woman and she had to put on

a white mask. for the camera to see her so it means that we're not making technology that works for everyone. but making research more inclusive does not simply mean including an equal number of men and women the european commission has recognised this and has introduced conditions for receiving funding from its 85000000000 euros research and innovation budget. to qualify for horizon europe funding research is now have to incorporate sex and intersectionality into each phase of their work from research designed to data collection and analysis. much of our science and technology is funded by taxpayer money and if we as a society are investing in science and technology we want the results of that science

to be inclusive and to work for everyone across the citee not just a privileged few. together with the european commission in london has published 15 case studies serving as the best practice with a suitably diverse range of examples. fishing used to be a male demain in bangladesh but that's no longer the case specially designed nets now enable women to harvest fish from inland waters without getting the best armies wet and so independently feed their families. another example focuses on recommendations for urban areas to make them more family friendly and less cost centric. and one case study looks at the role of new technologies in consolidating gender stereotypes in the future. but all the areas where

an inclusive approach is set up. to requirements we're still discovering we're it makes a lot of sense it's possible that it's not relevant for mathematics pure mathematics and theoretical physics but we may just not have the research yet to know. case you were wondering a sea turtle sex is determined by the temperature of the sand its egg is incubated in global warming means 99 percent of those now born in the northern great barrier reef a female as in most areas it's only through understanding such deep connections that we can better protect our planet's complex ecosystems in future. now listen carefully who or what is making this noise.

he would think via social media channels. through to not only t.v. it sounds like a frog before the rain starts. amish elite wonders if it comes from dolphins. a rodriguez believes is the sound of bubbling. it makes other pub wonder what taste think of the bird going crazy in space on now at least we're getting closer in terms of location. based as david flint is again a road that the noise is from neutron stones. and stevenson luggers as it sounds like outer space and yes the sound is from space from a comment to be exact thanks for your answers. a question from data from the u.k. . who wants to. can you hear someone scream in space we're certainly used to hearing spaceships hum through the void or

seeing stars die in cataclysmic explosions but only in the movies space is a vacuum so there's no atmosphere to conduct sound waves. restrict. our ears wouldn't register i think that it's like the sounds gone dead. a supernova with musical accompaniment is far more impressive. but space probes carry devices that register oscillations and celestial bodies such as the sun. and the sun's internal nuclear convulsions generate tremendous shock waves nasa scientists have ways to translate them into sounds we can hear. the van allen space probes explore the radiation belt surrounding the earth that sounds of electrically charged particles held around a planet by its magnetic fields they too can be translated into sounds.

the children after us are meant tokamak can even sing at least when the magnetic field in it's with the nitty starts to oscillate. the data behind this cosmic melody come courtesy of the result of space probe. of our solar systems largest planet jupiter when nasa probe juno recorded this as it transited the gas giants magnetic field. voyager 2 has even sent us recordings that made an interstellar space the. what we hear reflects activity in billowing clouds of electrical charge gas.

in a supernova the star blasts out so much mass and energy but it bends the very fabric of space generating gravity waves. the us based lego detector listened in to such a cosmic quake for the 1st time as it was produced by the merging of 2 black holes left behind by supernovas. if outline is read by average family 5 years later. do you have a science history you'd like us to answer. it in as a video text over or smile if we featured on the show you get a little surprise from us as a thank you. come on just ask. dorries from the world of science are available online at e.w. dot com slash science or on twitter. such

as this video. these images give us an intimate look into the inner workings of the beehive. german researchers have recorded the social lives of the insects ever several months. among other things they were able to close the phone and the rearing of the offspring. from the naming of the eggs by the queen. to the feeding of the now the. all the way up to patients.

and the hatching of the young. mother clip show how the bees groom each other. and how they clean out deceased larvae by well you sing them. the researchers hope that the videos will how to better protect these fascinating insects in the future. without camera traps many exciting insights into animal behavior would be impossible. such as watching tapirs for example. video recordings also plan essential role in our next story but the 2 researchers in eastern germany also rely

on their own and if. there's a war just spend allocca and polar libya which are investigating animal tracks in the mountains southwest of dresden. she was like it was rooting with us now. from using guns with planes as a hollow these are hairs from a small mammal and small bones and teeth could be a martin or a small fox plentiful what they're looking for is evidence that wolves are living around here for a long time there were none in germany but now they're back not everybody is pleased about that. but when i started researching i just. given how polarizing. people can get so agitated about just a regular wild animal you can move on one reason for the upset is that wolves

sometimes kill livestock so it's important to establish where they live and loss and live it have been monitoring wolves since 2019 and has yet to encounter any face to face but he certainly heard. the recorded howling on his phone and in the winter they do find plenty of tracks. and. one fascinating aspect of researching wolves is that it's detective work and you're hardly ever see any album and you can infer an awful lot from the evidence you gather. it's a kind of scientific quest. and over. the 2 have set up camera traps and check them every fortnight or so they catch a lot but rarely what they crave to see. the

top followed here we rarely see them here. folks by daylight. wolf this time. but a few months ago one of their other camera traps did catch a glimpse of a wolf a rare sighting no packets known to actually live in this particular area. we only knew of wolves living in the flatlands in saxony really flat terrain unknown in the mountains and it was also your good books lucky it's a poem that bitch works for the 2nd bag museum of natural history and gurlitz and is involved in a german czech research project into wolves called ovide. that's what put in the project we've managed to prove there is a pack of wolves living up here on the mountain ridge but on the czech side of the border we call a division ipac because they live near vision e.

that was in january 28th seen on what's with us. because the pack had offspring on check territory it's considered check but the wolves do come calling on the german side of the border as well. zoologists can only declare a pack resident in a given area if certain criteria are fulfilled. when it. is a scientific activity science requires rules. to prove a wolf is living somewhere it must have been there for at least 6 months. the evidence has to involve genetic material that is samples but we're not finding any at the moment. the starting today is not their day the 4th camera trap also fails to deliver and for that fine and not even over whiff of

a wolf disappointed. when i set out to spot a wolf i never do lines in and when i'm not expecting to see one there it is right in front of me and i don't have my camera with me nonetheless the 2 are pretty certain that walls will be settling and the german part of the ants get bigger mountains it could be any day now. this is the so-called hybrid x. which is between operating on gasoline and battery powered. meals are a cross between a horse and a donkey they are also hybrid. the e.u. is considered a hybrid political system and reinforced concrete a hybrid building material. you come across things that are cross combined all mixed like this in many fields and. on the football field. all ice here are on the ball and the goal scorer. but not on the pitch

itself it often looks like a strip of wasteland especially the goal mouth where it's objecting to the worst wear and tear. one potential solution is using synthetic fibers to reinforce natural grass that's already being done by some professional football teams in germany and a recreation complex just outside munich. and the natural grass pitches here are top quality but there was room for improvement and one particular area. is amy it's in the pool but this is the 6 yard box which gets the worst pounding shouldn't want to turn here you can see the line separating the area with hybrid mussing underneath and from the people a natural to them is a. hybrid turf contains around 20 percent synthetic fibers which have more of a mat surface 80 percent is lush green and bright or natural grass the end product feels like the real thing for footballers as opposed to purely artificial or

astroturf. hybrid turf has at least double the lifespan of its 100 percent natural counterpart but when it needs renewing what's left over is not compost as seen here at byron munich's ground but tons of plastic waste which eventually degrade into micro plastic the artificial mat underneath the natural grass should ideally be biodegradable. and that's where the scientists come in. félix echo is a postgraduate student at munich's technical university. he wants to develop eco friendly synthetic turf for football pitches last year he buried a range of samples here in order to study how they degrade. but where on earth is his test patch again. he was marked out with a mesh fence and bright orange drawled steve they were there to muffle the cation

of my samples and prevent animals from digging them up. the must have been somewhere around here you can with the best. meanwhile sports scientists at the technical university face problems of a very different nature this great flooring covers a number of measuring plates they will later be placed underneath the new hybrid turf the researchers want to record the forces exerted between players boots and the ground and hence on the player's joints to rule out any mishaps they 1st conduct preliminary tests. we attach markers to the legs for example they take precise measurements of movement between the bones they often fall off rendering those measurements invalid so we then have to start again almost with. the real test comes when an athlete runs across the measuring plates. hopes and we have an early exit one not so scientific insight here is that the leg

in question needs to be clean shaven prior to the tests. researchers from 2 different packages at the same university conducting 2 different experiments with much common ground both part of a project looking into hybrid turf. the sports scientists want to know how different surfaces impact on players joints muscles and ligaments the chemists meanwhile are tasked with ensuring that the bio plastic fibers degrade at just the right pace. félix eckel has now found the spot where he buried his treasured samples he chose an outdoor location to ensure the same kind of exposure to the wind and rain as a football pitch. spun exciting thing now is what the samples look like after they've been buried for over a year of a kind i still find them all have some biodegraded perhaps they're now discolored.

here's number 100 percent p.l.o. and still transparent no real change. he buried 14 bio synthetic samples in all 7 of them transparent and made of pure poly lactic acid used to make plastics. the other 7 had algae mixed into the. here we see a big difference it's spent in 2 places it feels like a cardboard news colors change significantly if not originally it was dark brown now it's yellowish green so in terms of degradation we can see far more change than with pure p l a p r. it remains to be seen though what this will mean for bioplastics in turf that

will need years of further testing. we go back to see if the sports scientists are on the ball they are using a special physical tracking device to look at how the number of studs affects football boot performance. why is that issue here when the research as such is about the new hybrid pitch surface. football is news different boots depending on the pitch our research will actually enable us to say which route is the most suitable for the respective stuff that involves looking at performance related criteria for the footballer because they have to be able to play well that 2nd league safety and injury prevention. postgraduate student félix echo claims and ways the samples he's retrieved. they're then left to dry out for 2 more weeks before further analysis subsequent tensile strength tests will indicate how brittle they become. for comparison he 1st tries

out some brand new test rod. book as his dissertation advisor says this is no luxury project to benefit a few footballers the results could help to stop the planet from choking on plastic waste. your. bigger problem is that we have 50 percent of all plastic ever produced lying around on landfills and it's gradually spreading into the world as micro plastic and other fragments leading to a growing mass of trash. that's why it's vital for us to make and use synthetic materials that are at least made from sustainable resources and definitely have to be bio degradable. which is why felix eckel and his colleagues from munich technical university will continue with their experiments. and this progress continues with the new biodegradable fibers

synthetic pitches are going green on a world beating level. that was it for tomorrow today. we have to see you again next time until then stay healthy and stay curious .
