practice or is that the nation for basically middle class 7 months before russia? tech ukraine, a filtering documents, daily life of the town? how are the people who are dealing with the growing tension? they change their world. we are with, you know, when i me inside starts going on dw, we still don't know what sounds done and so it was made. but there is plenty we do know about them, tends to fossil signs around the won't stay tuned for one very special discovery. instead of a fascinating stories on the w sign show. welcome to

tomorrow. today the, these bamboo barrels haven't been open for over a century despite their own valuable contents. discovering townsend and then again, call on me today they tell the story of the story tend to grow expedition during which some 250 tons of dinosaur bones were excavated and taken away to bowen. now researches are looking inside the bottles with the help of a c t scanner. the results of boston, i think and also revealing when it comes to gym and colonialism. this is the world's largest mounted dinosaur skeleton jeff titan, drunk i called oscar. that is a, he's 13 meters,

27 til around 23 meters long. and how's it going? this will would record entry to prove it. today oscar takes pride of place and buildings, natural history museum. he's also a treasure for researches and the museum is probably until logical collection headed by tanya shots. the idea off of the tongue, the dresser tighten is one is the knowledge of sort of pulse the res. so it essentially stands for that entire great is a cancer cooper does all the largest land dwelling village rates of old time that's highest. and most of these dinosaurs would be a 150000000 years ago in east africa. and present day tons and a half that bones were dug up during the 10 to google expedition and colonial german east africa. the tend to go to the expedition is still considered one of the most successful vertebrate poly until energy expeditions because of the variety of

dinosaurs that you don't have in a minute to be smaller area, longer form signed, typically beneficial, but a colonial undertaking. it's an issue being examined by, you know, a whole month from buttons, natural history museum. the excavations took place between 19091913 at 10 degrees of hill and southeastern tons in the one of the expedition latest kept a gentle jim and patty and told her just that no young inch understand that the dog, the end of this visit postage right at the beginning, where he writes that ideally they would like to tell them the entire hill on in the style. and in the end, they took away an incredible $250.00 tons of rock fair flushed. and it's hard to imagine how they actually moved it. you know, we need to remember people moved it by 120 some of the ducks. i'mma from was around

500 local people, took part in the excavations thinking of the petrified fossils and putting them in clay in savannah across and then into a wood crate, sol, bamboo barrels, all documented on camera. these in the, as is common with racist colonial imagery. these people are not usually named, but of course it keeps repeating the perspective of looking at people who we can't name, but who are absolutely crucial to the expedition. it is to an absolute north when each month those workers then carried the bustles to the port of lendy, 4 or 5 days journey on foot, $250.00 tons of fossils. over the course of 4 years from there, the congo was shipped to bill in of the yeah, the sheer number that she and i'm on the phone really good. it's in this

expeditions to the side talk is electra at the university of doris. so, um, in terms of a yeah, he's researched the oral history of the expedition. so i would say probably this, but i told her just okay, it didn't affect her just okay. we're doing this kind of specialized this by is already kind of walk ok. but the extra doing of it was, was standing by and i see advance and this is very important because it's been i to default around the functions that, that big of addition actually was in. they made their way to of, of the guns no doubt about the fossils were cleaned and pieced together at the museum and fell in the dinosaurs onto this day. the absolute show piece here get the colonial origins. how the last thing legacy do you have in general paula from the full that still has a dinosaur named after him? the diesel off to source letter full, becky. and then that's the issue of compensation. so you have now decided to kind

of use amount of if you to just some of them say ok, we need to do we need, we need to be events box, but us. so we have something with some, some advice or say okay, no, we don't need to be this the this box. but so just to the government, the given a government should be paying for so money to the communities for protecting these that are the names about which actually belong to this area. often double is hard headed, takes most of the tend to grew fossil. it's currently lying. the lot brent find all kinds of buildings, natural history museum. they're still being used to research, to find out how dinosaurs moved for example, and precisely where the muscles were attached. but even over a century later, some quite, some barrels remain unopened. on the positive side,

the packaging itself serves as historical evidence about the expedition is up almost in gop steps, found a degree in abundance in the area and it grew but quickly of to be included expulsion enough. these are found the wooden desk we see at the end here was imported from scandinavia, which i think because they didn't have any big trees on the ground bar. my daughter and i didn't catch the announcement here. so then then you can see a bit of symphonic gras sticking out here. it was used to prevent the contents from moving around, doing transport from the service provision contraband transport. the contents of the bottles, however, are as yet unknown um, potentially valuable fossils to be able to look inside without destroying anything . any other thoughts has brought the containers across spelling to the license institute for sue and wildlife research. here veterinarian key does which normally perform the c t scans and living breathing animals. not

a 150000000 year old phones and 100 year old barrels. the honda wouldn't live in nails land by la festivals, image and there is indeed a little treasure hiding in this bottom blue barrel tools that looks like the bar. yes. that's the rest of the tool. amazing. it really is the rest of the lower tool . yeah, i'm just gonna close and look at the scan video to 3 of your remnants from the smooth dice and low to store. this is all that's quite special for us because we only have a few sco remains from these dinosaurs. zoe, i'm leaving the joe even still has a 2 senate that's that's the route here on the other pieces contains smaller replacement months. apparently these dinosaurs change the teeth. this you and you

are using strickland. i'm switching to get my hands on this piece because it's so special from stuff is on the us. perhaps the spiral will be opened and she'll be able to carefully get to grips with the dinosaurs level, a jewel. until then, scans of the other $29.00 barrels will deliver further insights into that pre a start contents on gym and colonial history via owns it. any dinosaurs roaming tips on it today? the most likely reason is an asteroid, striking this around 66000000 years ago, also wiping out countess other living beings. the imagines and disappearance of species is inevitably influenced by environmental factors. changes in local conditions are evidently having an impact on the 5 site. researchers have been conducting an in depth study on the causes of its dwindling populations. in many cases, the insects have difficulty even guessing together the

love at 1st sight. the most, if you can no longer track that special, someone down for glue was finding a made is no easy mountain nowadays. that's thanks to our ever bright of cities. female blue ones comp fly. so they rely on that bright glowing rear end to attract upon us. oh, biologically, put a bio chemical reaction takes place in the cells of their wrapped them and it involves new super run and a t p and leads to energy being produced in the form of night. this is known as bio human essence, but kind of competes with artificial lines. the recent studies sent male blue ones into a maze to search for a female mate. they were varying amounts of lights in the mains. when it was docs and male, found the female every time that on the street night condition. and only if we face smell managed the artificial light likely tassel, the beetles. so let's turn off the lights more often and give the glue when some

private time, the red right now, you know why, why applies slow. got another size question, don't wait, just send it in as a video, text or voice message. if we answer it on the show, you get a special surprise as a thank you. come on just on this week's question comes from is on chill, cool is the a mock who in nigeria, the wire airplane wings bit at the ends to understand the function and benefits of these wing limits or winked up devices. let's look at the air flow around the wings, due to its shape. a plane wing triggers differences in pressure above and below. and that's what produces the lift. these pressure differences cause air to flow in

the direction of the wing tip and spill over and creating swirling air masses called forth to cease trouble. is they flow counter to the planes flight direction and counteract the lift. this is known as induced drag the wing looks links in the roof, the air most travel to reach the wing tips. this makes for smaller and slower, vortices induced drag is reduced, and the wings generate more lift in 19 seventies richard t whitcomb. the aerodynamics specialist at nasa investigated the air flow around planes and conducted the 1st successful test with wing. let's see, made an astonishing discovery. a plane with wing lives can ascend quicker while using less fuel than an aircraft with the same thrust and wing span. so, but no weight of devices on long haul flights that can result in kerosene. savings of up to 5 percent,

even the wing. let's add more weight to another advantage. less wake turbulence which can pose a danger to planes when they fly close behind each other. that's especially important during starts and landings, because the aircraft must come and go in quick succession. so winland's allow for a greater frequency of take offs. 10 landings the did you know that those old imposing twins that's mimic mother nature. lots of pets that have most of the out of soaring like buses, eagles and stokes. have they when the hips turn that? well flying that gift of evolution lens, the maximum list and energy efficiency, the, the go to movie rio, featured supplies of a more delicate beds. b, c's. ah, good morning,

lou isn't blank, gather bird. he never learned how to fly, but these are found to discover how he really lose the last may i have a kind the only other blue mccaulhey seen rio de janeiro. that's where the slicks as mccaul used to be at home before becoming extinct in the wild, 20 years ago. a development that through all the just trying to with us the moon is still visible when you 1st hear them. they are cromwell purchases, alarm clock. he is the wallet, just biologist, and a kind of manager for the specs in the cause. and right now they're demanding their breakfast. mixture and whistles are as similar as possible to food in the wild once they eating

a little bit while they able to put together guide books and they give typically we don't always have that available. so we have to use what's available to us to try and limit some of those i eat spits as my cause, have been flying around the college in the wilderness, in ne, brazil for several weeks now will be introduced. the animals 1st have to get used to their new found freedom. they come whenever they hear cromwell purchases quad feeding time. we have to stay back. the animals are supposed to be becoming less used to people. these birds have never been in a while before. they've been those fixing the wild for more than 22 years. so teach them we don't want them to stop. and we don't want them to be weak and stressed about not having enough food and then phone level. so we make sure that they have food available, and they are healthy while they fund the wild food. let's fix this because our,

like celebrities, people from neighboring areas want to see the birds. only older residents can recall the time before they died out in the wild. people like 84 year old joseph adults santos. like, that'd be like one va. when i was on the battery, i saw the birds near a house at the river as they wash slow. yes, he asked, i don't, but when i was out heard him go with the dialogue with a local community is important to biologist go. i say there help is needed to make the reintroduction process a success. i can pull up if i so that i mean we have to maintain this fixed as a habitat if we want to protect those equities, these things. and that requires the dedication of people who live here. so it's because they have to monitor. and ultimately, that is, that is the,

the animal's extinction in the wild, 20 years ago was also linked to the way people here live farming, good hurting out all typical of brazil's bearing north east. but these practices are destroying more and more habitat. poaching was the last straw for them because habits, it was probably the key that brought the numbers down to very little and said to me, and once you get to that point, they become very valuable to a collector. so the river, they all the more valuable that they are. so suddenly they surprised when they had good, bigger and bigger. the animals return is thanks to a complex breeding program that was supported in part by the brazilian government. a german non profit association led the breeding program using animals from the inside of the owners. and a former amir from guitar made his biggest collection available. genes are analyzed

to reach the best results, a complex project costing millions, finance primarily through donations. 50 to 6 is because travel to brazil where they were met at the airport by cromwell purchase, basically new arrivals of the piece in the country. so it was fantastic. but how can a new vi piece be made to feel at home again and be able to survive in the future? scientists, biologists, and indeed those are working together and measuring things like how far the birds fly. everyone agrees that it can only work if the destruction of habitat is halted . 40 percent of the college and got has already been destroyed. thing was i can google iceland and his team visit local farmers each week. most like your model santos live by raising animals and saying everyone here raises goats. i want to have a lot of them just a few more than one, but everyone has something to do with codes and good ones. they can best survive. and this throughout written area of campbell,

the ice is trying to convince the farmers defense in their animals to allow nature to recover the heart of sparked, you know, to change the mindset. they are the code sure that they have here the years that came from their parents didn't grandparents. so it's quite hard to understand how the thoughts are connected. she is relying on the younger generation in the city of kudos that to speak to them because it has already made an impression even in this elementary school the i want to because to come back to that, a city becomes more beautiful, a promotion campaign. and i kind of hands on education that's with work trying to bring back and now the proud to be trying to speak to nicole,

the proud to protect the environment. the proud to be from pets in the hope is that the speaks is because, well, breed and settled permanently. it could serve as an example for helping others bases on the brink of extinction. recent years i've seen the appearance of kansas nice the seas science teaching that so can that is to use we now know that there are 4 types of 2. well, for example, the southern drops of my size are off the ridiculously, to off ends in northern, to rock on a slightly smaller scale as a new species found up in germany. this is a story about an exciting find that surprised even the expense about research. and one of your knowledge is biological collection. and the way modern technology to make the indivisible visible are actually seated with scans, many things,

but never had anything. this spectacular form of miss scott yvonne. we were amazed to find this. we've never seen anything like it before. so last year we didn't expect to find something i thought in this area. the story began to show a back, a need to visit if need to bring in, in germany, biologist, marina. and what was that and had colleague regularly set top 10 like structures on this hillside, the phone, the video, it has its own micro climate, which makes it particularly interesting for the insect researches. the 10s function is insect tops enabling 1000000. and what was it to record? how the species had changed in number on composition? well now excuse me. in fact, if the index fly up the middle of the top, there's a hole in a buckle. definitely the insects like into the buckling but a phone and to 80 percent alcohol, which preserves them for us as get him off there is still insect groups including

haven, gemini, instead of hardly been studied gone. it's when we know next to nothing about that really awesome projects like our trumps, allow us to regularly find new species in these groups to show a bag with its meadows and squatted fruit trees is the ideal place for this kind of research. the district got state museum of natural history, nothing. and what was it? again, her usual process of analyzing the insects that had landed in the trap using a microscope. she sold it, them into space, sees in size, they were just a few millimeters in size, belong to a family of law. but then she found something she had never come across before. the except lawson and i found the 1st specimen of the new species almost by accident. i was searching through the insects and found one look different from the

others known as looters. i have had a row to spikes on the abdomen, kind of on so far. no other was that i had found a hot fat. and so i began comparing it to open noon species to see whether it might be something completely new. that no one had discovered yet just kind of the top. and that's where las kaufman comes in. a scientific director and head if the stroke got museum of natural history, he and his team have access to one of your it's not just insight collections. it comprises nearly 5000000 specimens, 350000 of which belong to the order of hyman altura. so ends these and wasps the inch monitors compare the tiny was that it's the ration is on the optimum with existing species. after a certain analysis, they concluded that this was indeed a new discovery. press on says,

he realized how does this, what surprised us is that such a striking species can be found in gemini, visited the isaac. this is the only known species of power. so toyed watson with this particular ro stole into the end of its optimum nights. and this is there a hundreds of thousands of species, housing, the infant that this feature has never been seen before. us, it's never been discovered. when done, that could be the sort of tomorrow that can probably do something very special and let us help this particular species and it's biology. so the research will now be needed to find out what exactly that function is. of course i'll try to continue studying specimen. melina melissa cafferty, places it into a special container. she wants to take a look deep inside the was the, the concert institute of technology as a special piece of equipment which were unable had to do just that. it's a high throughput x ray might crazy to scan it,

but this is on the particularly well suited for creating 3 dimensional images of insects as well as other small samples of the so it's used in biology but also for materials research, for example, produces 3 dimensional images of small samples showing a high level of detail, these are longer type the complex piece of digital technology will help unlock the secrets of the new species. it's a special form of computer demography that can reveal the inner workings of specimens that are just if you might could meet as in size the latest highest award . we see all the details space, the outside which we've already seen on the microscope. but we also see the muscles inside. we see the repository used for laying x, and it's only very high resolution. such discoveries represent lucky moments of biologists. because many of these, these disappear before we even know they exist. marina moser is determined to do

her best to avoid that. she'll keep searching for the unknown right here on her doorstep the, that's it. so this episode of tomorrow, today, your d w sign shall see you next time. and stay curious by the, the, the,

a pulse, the beginning of a story that takes us along for the ride. it's about the prescriptive culture

information. this is the, the news w mines. it's cold read for here for every year. terrible fires, rage across the continent. protecting these eco systems from the flames is more important than ever. we meet people from spain and germany who want to make a difference. they share their ideas and their great passion for the for the close saw in 75 minutes on d, w. the little guy, this is the 77 percent of the platform for the issues share idea. you
