discovery. subscribe to. documentary. it's fascinating how different people. but research doesn't always we flicked 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. . for every $100.00 researchers in the natural sciences

worldwide on average only $28.00 of them all women. the ratio of men to women is almost 5050 in 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 polls 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 that. doing research

wrong can cost lives and money. has spent 4 decades exploring and enhanced saying the fundamental bases of research. dependable study she reveals those that take in fact his relating to sex gender and intersectionality from the outside. 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 bind the re categories which is why biologists now talk of a 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 u.s. 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 a further examples it's been known for some time that women have an almost 50 percent higher risk of soft. bring 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 to get a peon commission has recognized 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 sighted 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 their saris 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 surplus. 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. and in 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. listen carefully who know what is making this noise.

via social media channels. or to not only t.v. it sounds like a frog before the brain starts. wonders if it comes from dolphins. rodriguez believes it's the sound of bubbling. it makes all of our public do what they think of the bird going crazy in space on now at least we're getting closer in terms of location. places david flint as we get a road that the noise is from neutron stars. and stevenson love us 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 dale from the u.k. . 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. just straight. out is wouldn't register a thing 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 the planet by its magnetic fields they

too can be translated into sounds. the children of gerasim enco comic 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. into the solar system's 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 our electrical charge gas.

in the 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 outlet is right why average family 5 years later. do you have a science mystery you'd like us to answer. it in as a video text over a smile if we featured on the show you get a little surprise from us as a fact you. can just ask. dorries from the world of science are available online at g.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. genin reset is have recorded the social lives of the insects every several months. among other things they were able to closely follow and the rearing of the offspring. from the naming of the nx by the queen. to the feeding of the now the. all the way up to patients.

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

on their own and. just spend and power libya are investigating animal tracks in the mountains southwest of dresden. looks like it was rooting with us now to. see a sequence with lines like a hollow these are hairs from a small mammal and small bones and teeth could be a martin or a small fox i know folks 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 wolves i discovered how polarizing and it's all good people can get so agitated about just a regular wild animal could be. 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 hardly ever see any. you can infer an awful lot from the evidence you gather. it's a kind of scientific quest. and then there were. 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.

follow deer we rarely see them here. for fox by daylight. hare. no 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 pack is known to actually live in this particular area. we only know of wolves living in the flatlands in saxony really flat terrain and none in the mountains and. your books largely it's a polyp it works for the 2nd bag museum of natural history and gurlitz and is involved in a german czech research project into wolves called ovide. 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 these loony that was in january 28th. because the pack had offspring on czech 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 that the evidence has to involve genetic match. cereal that is samples but we're not finding any at the moment. the sign today is not their day the 4th camera trap also fails to deliver on to the fun and not even of whiff of

a wolf disappointed. when i set out to spot a wolf i never do the 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 walt's will be settling in the german part of the answer given the mountains it could be any day now. this is a so-called hybrid it switches between operating on gasoline and battery power. mean lives are a cross between a horse and a donkey they are also hybrids the e.u. is considered a hybrid political system and reinforced concrete a hybrid building material. you come across things that are crossed combined all mixed like this in many fields including on the football field. all ice here 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 objected 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. the natural grass pitches here are top quality but there was room for improvement and one particular area. is amy it's in the top this is the 6 yard box which gets the worst kind of ending shouldn't wonder she turned here you can see the line separating the area with hybrid mussing underneath and from the people a natural to the. 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 faded 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. with a mesh fence and bright orange drugs they were there to mark the location of my samples

and prevent animals from digging them up. the must have been somewhere around here . 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 hands on the players joints to rule out any mishaps they 1st conduct preliminary tests. we attach markers to their legs for example they take precise measurements of movement between the bones they often fall off rendering those measurements invalid so we don't have to start again. 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 faculties 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 echo 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 the 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 p.-l. a poly lactic acid used to make bioplastics. the other 7 had algae mixed into the p l a. here we see a big difference it's bent in 2 places it feels like a cardboard one is 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 a p.r. . it remains to be seen though what this will mean for bioplastics inter-faith that will need years of further testing. we go back to see if the sports scientists are

on the ball they're 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 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. locks. 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 tests our strength tests will indicate how brittle they've become. for comparison he 1st

tries out some brand new test rod. 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 great on

a world beating. that was it for tomorrow today. we have to see you again next time until then stay healthy and stay curious .
