to consider as well. the future is being determines now. europe revealed parts for in our series. in 45 minutes on dw, we've got some hot tips for your bucket list. romantic corner check. spot checks and some great culture memorials to vote. w travels off, we go, the we still don't know what sounds dinosaurs made, but there is plenty we do know that about 10 times 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 opened 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. 10 to grow expedition during which some 250 tons of donna's old bones were excavated and taken away to the island. now researches looking inside the bottles with the help of a c t scanner. the results of fascinating and also revealing when it comes to gym and colonialism. this is the world's largest mounted dinosaur skeleton jeff titan, brown guy called oscar. that is a, he's 13 meters, 27 til around 23 meters. long. hello. 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 the tongue, the dresser tighten is one of the knowledge is sort of post the res. so it essentially stands for that entire grade is a counselor cooper does all the not just land dwelling vertebrates 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 in that bones were dug up during the 10 to google expedition and colonial german east africa. he attended the expedition. it's still considered one of the most successful vertebrate poly ontology expeditions because of the variety of dinosaurs,

the dentist and event it to be small area in the home 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 190-919-1310 degrees of hill and southeastern tons in a one of the expedition latest kept a gentle german patty and told her just that no young inch understand that the though the end of this visit postage right at the beginning, where he writes that ideally, they would like to tell them the entire hill, putnam the style, and in the end, they took away an incredible 250 tons of rock fair flushed. and it's hard to imagine how they actually moved it. but no, we need to remember people moved it by 120 some of the ducks. amazon 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. sole 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 will absolutely crucial to the expedition to the next that it's showing up . so note, 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 yeah. number the she and i'm on the phone really good. getting this expedition

to that out. who says sad talk is electra at the university of doris. so um, in terms of the yeah, he's researched the oral history of the expedition. so i would say probably this, but i told her just ok the given effect her just okay. way of doing this kind of sponge xyz is by, is already kind of walk ok, but the extra doing of it was, was done by enough events. and this is very important because it's been i to the foreground because of that. that fixed condition actually was in, they made their way to of actually got 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 jim and general paula from the full back still has a dinosaur named after him. the diesel to source letter full, becky. and then that's the issue of compensation. so you have now divided it kind

of use of amount of if you to just some of them say okay, we need to do we need, we need to be in that event spot. but us, so we have something with some some advice or say ok, no, we don't need to be this the, the mess back by. so just to the government, the government, the government should be paying for some money to the communities for taking these that are advanced about project shutting. grimley to this area of to double is, are headed to most of the tend to grew fossil. it's currently lined the lot print fine, all kinds of buildings, natural history museum. they're still being used to the research to find out how dinosaurs moved, for example, and precisely where the muscles were attached of the 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 that the most in gaps that filed a degree in abundance in the area? i agree but quickly of to be included expulsion enough because of almost the wooden disk we see at the end here was imported from scandinavia, which i'm because they didn't have any big trees on the ground bar. my daughter and i didn't catch her when i'm sick, my initials and then you can see a bit of symphonic ra sticking out here. and it was used to prevent the contents from moving around, doing transport from the service provision contraband transport. the contents of the barrels, however, are as yet unknown and potentially valuable fossils to, to be able to look inside without destroying anything. any other thoughts has brought the containers across spelling to the license institute, wazoo, and wildlife research here veterinarian key to switch normally perform the c t scans and living breathing animals. not

a 150000000 year old phones and 100 year old barrels behind a wouldn't let a nails live by a the festivals image and there is indeed a little treasure hiding and this bamboo barrel tools that looks like the back part . yes, that's the rest of the tool. amazing. it really is the rest of below, which will give you. i'm just gonna close and look at the scan. revealed 3 of your remnants from the smooth dice and low to source is all that's quite special for us because we only have a few sco remains from these dinosaurs. zoe, i'm refund even from the jo, 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 itching 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, low jewel. until then, scans of the other, the $29.00 barrels will deliver further insights into the prius, start contents on gym, and colonial history via owns it. any dinosaurs running the planet today. the most likely reason is an asteroid, striking this around 66000000 years ago. also wiping out countess other living beings, imagines and disappearing. subspecies is inevitably influenced by environmental factors, changes in local conditions, 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 a glow of finding a made is no easy mountain. nowadays. thoughts thanks to our ever bright cities, female blue ones comp slowly, 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 lose different 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 off the official lines. a recent study sent, mailed blue ones into a maze to search for a female mate. they were varying amounts of unites in the maze. when it was dogs and male found the female every time that on the street night condition, the only f we faced smile managed, the artificial lights likely tassel, the beetles. so let's turn off the light small roof and gives the glue. when some

private time the blood is red, why now? you know why, why applies low. got another science 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 and 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 in creating swirling air masses called vortices. trouble is they flow counter to the planes flight direction and counteract the lift . this is known as induced drag. the wing looks linked in the roof, the air must travel to reach the wing tips. this megs 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 investigating the air flow around planes and conducted the 1st successful test with wing. let's see, made an astonishing discovery. a plane with when lives can ascend quicker, while using less fuel than an aircraft with the same thrust and winks man, but no winked of devices on long ha. flights that can result in kerosene savings of up to 5 percent. even the winland's add more weight. another advantage less

wake turbulence which compose 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 wing, let's allow for a greater frequency of take offs and landings the, did you know that those all important wing that's mimic mother nature. lots of beds that have most of the out of soaring like buses, eagles and stokes. have they, we should turn that well flying that gift of evolution lens, the maximum list and energy efficiency. the, the cartoon movie rios fetus applies of a more delicate beds. b, c's. ah,

good morning. blue isn't like other birds. he never learned how to fly. but these are found to discover how he really lucas last may. i have a kind the only other blue mccall leasing rio de janeiro. that's where this fixed 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 spreadsheets that

as similar as possible to food in the wild once they eating a little bit while they able to put together diet 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 limited some of the 8 spaces. macaws 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 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 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 guide you on the 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 the spaces habitat if we want to protect those equity. serious thinking and that requires that dedication of people who live here. so it's because they have to monitor and ultimately that is that any of the, the animals 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 said to me, and once you get to that point, they become very valuable to a collector. so the river, they are, 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 the former amir from guitar matrices fixes, collection available. genes are analyzed to reach the best results,

a complex project costing millions, finance primarily through donations. 526 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 the new v i p be meet to feel at home again and be able to survive in the future? scientists, biologists, and in videos 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 content that 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 for everyone has something to do with codes and good ones. they can best survive in this drought 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 tried to speak to me, call the pro,

to protect the environment. the proud to be from catching up. the hope is that the speaks is because, well, breed and settled permanently. it could serve as an example for helping others. these, these on the brink of extinction. recent years, i've seen the appearance of kansas nice theses science teaching that so can now disease. we now know that there are 4 types of to run, for example, to southern dropped the most sizer off the ridiculously, to off ends in northern to run on a slightly smaller scale. here's 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 from an 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 need to visit if need to bring in, 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 chops 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 index fly up the middle of the top, there's a hole in a buckle. definitely be in 6th like into the buckling with a 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 scottish 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, belong to a family of law. but then she found something she had never come across before. the fairfax, i'm flossing and i found this the 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 abdomen kinda and on so far, no other was that i had found a hot spot and sat. and so i began comparing it to all the known species to see whether it might be something completely new. that no one had discovered yet just kinda at 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 boss with 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. one says he lost his, the thought 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, i'm always a catholic, 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 democracy that can reveal the inner workings of specimens that are just if you might, could meet as in size. you see an edited highest award. we see all the details base the outside, which we've already seen on the microscope. but we also see the muscles inside. we see the i'll be pleasant to use for laying eggs and it's old and very high resolution. such discoveries represent lucky moments the biologists, because many species disappear before we even know they exist,

nothing. and what was that is determined to do a 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 science and see you next time and stay curious by the the, the

democracy takes back sort of control of the essentials. the digitalization offers europeans, many opportunities, but there are risks to consider as well. the future is being determined. now.

europe revealed parts for in our series. in 15 minutes on d. w. in good shape. excuse me, can you repeat that ex, that's mean hearing losses on the right. the main reason is excessive hedge fund of news and the young people are especially interested. how should we take care about hearing? using q tips is not the solution. good? 90 minutes, dw, the sometimes a seed is all you need to allow big ideas to grow. or to bring an environmental
