pulls into its history and meet its caretaker's minster. in 30 minutes on the w. w. west port winning offer is available world wide and for every language level, learning german has never been simpler. german to go we still don't know what sounds dinosaurs 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. he fell out of 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 a and then a gentleman called 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 fill in now researches of looking inside the bottles with the help of a c t scanner is the results of fascinating and also revealing when it comes to gym and colonialism. this is the world's largest mounted donna's soul skeleton. jeff a titan drunk i called oscar. that is the,

he's 13 meters, 27 tool on around 23 meters long. and how's it going? this will record entry to prove it. today oscar takes pride of place in billings natural history museum. he's also a treasure for researches and the museum is probably until logical collections headed by don. you shots the idea of off the tongue, the dresser tighten is one of the knowledge is sort of pulse the res. so it essentially stands about entire group is a cancer cooper does all the not just loved doing that the rates of old time and that's highest. and most of these dinosaurs would be a 150000000 years ago in east africa, and present day tons and in the bones were dug up during the 10 to google expedition in colonial german east africa. he attended the expedition. it's still considered one of the most successful vertebrate poly until naji expeditions

because of the variety of dinosaurs, the dentist and event it to be small. larry a long before that sign, typically beneficial, but a colonial undertaking. it's an issue being examined by you know, home on from buttons, natural history museum. the excavations took place between 190-919-1312 guru hill and southeastern townsend. they 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 ups of petrified fossils and putting them in clay in savannah across and then into would great soul bamboo barrels all documented on camera. these in the as is common with racist colonial imagery. these people are not usually named, then of course it keeps repeating the perspective of looking at people who we can't name, but who are absolutely crucial to the expedition to the next to it is to an absolute north. when they come on. 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 cargo was shipped to bill in a yeah, this year number the she and i'm on the phone. really good. getting this

expeditions to zillow, who says sad dog is electra at the university of doris in terms of now, he's research the oral history of the expedition. so i would say probably this, but i told her just if it didn't affect her just ok way of doing this kind of specialized is by is already kind of walk ok. but the extra doing it was was done by enough events. and this is very important because it's been i to the for brown, the company that the big physician actually was in. they made their way to of the guns. no doubt about the fuss. elizabeth cleaned and pieced together at the museum and fell in the dinosaurs onto the stay. the absolute show piece here. get the colonial origins. how the last thing legacy do you have in general paula from the full back still has a dinosaur named after him. the diesel off to a source letter for becky. and then that's the issue of compensation. so you have

now decided to kind of use a month if you to just some of them say ok, we need to do we need, we need to date that immense box but us so we have something with some some advice or say okay, no, we don't need to be this the day that it may as facts, 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 i've tried to do only to this area of to double it's hard headed, takes most of the 10 to grew fossil. it's currently lined the lot bring 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 stuff on the ground sticking out here. it was used to present the contents and 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 to switch normally performed the c t scans and living breathing animals. not

a 150000000 year old phones and 100 year old barrels. the honda wouldn't let a nails land by la festivals image and there is indeed a little treasure hiding in this bamboo barrel until that looks like the bar. yes, that's the rest of the jewel. amazing. it really is the rest of the lower jewel. how may i assist in getting a closer 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 services 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 barrels schools that have a further insights into that pre a start contents. and jim and colonial history violence at any dinosaurs roaming, that's 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, o biologically, put a bio chemical reaction takes place in the cells of their optimum. it involves new sit for rent and a t p and leads to energy being produced in the form of light. this is known as bio human essence. but kind of competes with also official likes. a recent study sent mail 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 mail 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 image area, 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 vortices. trouble is they flow counter to the plains 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. and with waiting lists, he 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. 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 beds 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 last may think i have a kind the only other blue mccaulhey seen rio de janeiro. that's where the slicks is. 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. spell as

similar as possible to food in the wild once they eating a little bit while they able to put together a diet. 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 spaces because 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 say that the animals are supposed to be becoming less use to people. these birds have never been in a while before. they've been us 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 santo's 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 clothes. yes. he asked them, but when i was out heard him goals. what kind of god dialogue with the local community is important to biologist go. i said 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 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 habit that was probably the key that brought the numbers down to very little. and that 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 animal's 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 dues and private owners. and a former amir from guitar made his fix. his 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 peace 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 santo's lives 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 eisler is trying to convince the farmers defense in their animals to allow nature to recover the heart of sparked, you know, change the mindset. they are the code sure that they have here the years that came from their parents being grandparents. so it's quite hard to understand how the thoughts are connected. g is relying on the younger generation in the city of kudos to speak to them because it has already made an impression even in this elementary school the i want them a cause 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 in the proud to be tried to speak to me, call the pro,

to protect the environment, to proud to be from catching up. the hope is that the speaks is because will 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 means theses science teaching us or canada sees . we now know that there are 4 types of to run, for example, to southern dropped the most size or off the ridiculously, to off and the northern to run on a slightly smaller scale. and these bases found up in germany this is a story about an exciting find that surprised even the experts about research and one of units knowledge is biological collection. and the way modern technology to make the invisibles physically seated with scans, many things,

but never had anything. this spectacular event. we were amazed to find this. we've never seen anything like it before. so that's good. we didn't expect to find something. and i thought in this area, the story began to show a back, a nature was if me, a tubing and in germany, biologist marina. and what was that? and had colleague regularly set up 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 movie and what was it to record? how the species had changed in number on composition were not, excuse me. in fact, if the insects fly up the middle of the top, there's a hole in a buckle. definitely the insects like into the buckling, but they phone and to 80 percent alcohol, which preserves them for us. escape. there were still insect groups including haven,

gemini, instead of hardly been studied, just gone. it's when we know next to nothing about the awesome projects like our trots, allow us to regularly find new species in these groups. to show a bag with its meadows and scattered 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 trunk using a microscope. she sold it them into space, sees in size. they were just a few millimeters in size and belonged to a family of wasps. 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, unknown as looters. i have had a row spikes on the optimal kind of on sofa. now with the water that i had found a hot button, fat. and so i began comparing it to open noon species to see whether it might be something completely new and that no one had discovered yet just kinda at the top. and that's where las kaufman comes in. a scientific director in head, if the step 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 heim and not threat. so ends these and wasps. the inch monitors compare the tiny boss with it's the ration was on the optimum with existing species. after a thorough analysis, they concluded that this was indeed a new discovery. wrestling says he, well,

i said this is 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 was with this particular ro, stallings at the end of its optimal nights. and this is there a hundreds of thousands of species 1000 in front that this feature has never been seen before. but 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 has 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 fitness particularly well suited for creating 3 dimensional images of insects as well as other small samples. it will be so it's used in biology, but also for materials research. for example, it produces 3 dimensional images of small samples that are showing a high level of detail. you've got a lot of time. the, the complex piece of digital technology will help unlock the secrets of the new wasp 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. you see, i looked at 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. nothing. and what was that is determined to do our best to avoid that. she'll keep searching for the unknown right here on her doorstep the that's it for this episode of tomorrow today, you dw sign should see you next time. i'm stay curious by the the the

can i conic monument that also holds a world record to this very day. who cathedral the tallest church in the world? we climbed the steeple, delve into its history and meet its caretaker's minster.

coming on d. w, as in good shape. excuse me, can you repeat that ex, that's mean hearing losses on the right. the main reason is excessive headphone use . the young people are especially interested. how should we take care of a hearing? using q tips is not the solution which in 30 minutes dw, the sometimes a seed is all you need to allow big ideas to grow or to bring an environmental

conservation to life with learning facts like global ideas. we will show you how climate change and environmental conservation is taking shape around the world and how we can make a difference. knowledge grows through sharing, download it now for the interest the global economy portfolio g w, business b on. here's a closer look at the project. our mission to analyze the flight for market dominance. this is where the heck with dw business b on the one of mankind's oldest ambitions could be within reach. what do you see?

it really is possible to reverse the researchers and scientists all over the world for you know, race against time. they are peers and rivals with one daring goals to help smart nature. the more likes watching it on youtube, dw documentary, the this is to go during use, and these are the top stories. violence protests covered up to the gantt and cities in thousands, across from the following. the few people, the shooting of a 17 year old always do it in a traffic stop on tuesday. a tardies have destroyed houses of.
