of the 60 minutes d w very, what do you love about anything away from the fund? i'm not even allowed to go to my own car and everyone with little holes and every single day stuff. getting you ready to meet the gym and then join me right? just do it on dw. we still don't know what sounds dinosaurs made, but there is plenty we do know about 10 times to fossil signs around the won't. stay tuned for one very special discovery. he fell out of fascinating stories on dw sign show. welcome to tomorrow. today the these

bamboo barrels haven't been opened for over a century. despite their own valuable contents. discovered in tons and a and then a gentleman called on me today they tell the story of the historic tend to grow expedition during which some, 250 tons of dinosaur bones were excavated and taken away to bill. and now researches are 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 dinosaur skeleton. jeff, at tied to him drunk, i called oscar. that is the he's 13 meters, 27 tool, and around 23 meters long. and how's it going? this will direct 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 don you shots the idea of off the tongue, the dresser tighten is one of the knowledge is sort of puts the res. so it essentially stands for that entire group is a counselor cooper does all the largest long dwelling village 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 attends expedition is 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 sign 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 190-919-1312 guru hill and southeastern townsend. they one of the expedition leaders 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 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 good, great soul bamboo barrels, all documented on camera. these in the, as is common with racist colonial imagery, and 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 to the x that it's showing up. so, you know, depending on those workers then carried the fossils 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 the sheer number, the sheer number before we were getting this up. expeditions to zillow, who says doc 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 about this, but i told her just okay, they don't affect her just okay. we have rooms 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 ground 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 the state. the absolute show piece here. yet to colonial origins of the last thing. legacy jim and general paula from that the full back 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 date, it's a bit immense box but us, oh we have something with some some advice or say okay, no we don't need to be this the, the 30 minutes backs by so just through the government, the government, the government should be paying for some money to the communities for protecting these that are the names above project shutting down only 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. and it grew but quickly of to be included expulsion enough because of 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 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 present the contents and moving around, doing transport from the service provision, contraband principled. the contents of the barrels, however, are as yet unknown and potentially valuable fossils to, to be able to look inside without destroying anything that you have. a shroud says brother contains across spelling to the license institute for sue and wildlife research. here veterinarian key does which normally perform the c t scans on living, breathing animals. not a 150000000 year old phones and 100 year old barrels. the

honda wouldn't let the nails live via the festivals image and there is indeed a little treasure hiding and this bamboo barrel tells me that looks like the bar. yes, that's the rest of the jewel. amazing. it really is the rest of the lower jewel. it's in then it's getting a closer look at the scan revealed to 3 your remnants from the smooth dice and low to source results. 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. sometimes small and a replacement months. apparently these dinosaurs change that a sponsor issue and you can strip it seem 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 jewel. until then scans of the other 29 barrels will deliver further insights into the prius. start contents on gym and colonial history via owns it. any dinosaurs roaming the pes on it today. the most likely reason is an asteroid, striking this around 66000000 years ago, also wiping out countess other living beings, imagines and disappearing. subspace ease is inevitably influenced by environmental factors, changes in local conditions, evidently having an impact on the 5 site research as 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 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 that wrapped them and it involves to be 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 also official lines. a recent study sent mail blue ones into a maze to search for a female mate. they were varying amounts of unites in the maze. when it was docs and male, found the female every time that on the street night condition and only if we face smile managed, the artificial lights likely dazzle 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 and 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 links 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, in aerodynamics specialist at nasa, investigating the air flow around planes and conducted the 1st successful test with wing was 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 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 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 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 when hits, turn that? well flying that gift of evolution lens, the maximum list and energy efficiency, the, the cartoon movie really features applies of a more delicate beds. b, c's. ah, good morning. lu isn't like other birds. he never learned how to fly. but these are found to discover how he really blew in

last. may i have a kind the only other blue mccall leasing 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 mix pretty missiles, it's better to as similar as possible to food and the wild ones. they 18 older 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 limited some of those i eat spaces. my costs have been flying around the college and googled in this. in ne, brazil for several weeks now will be introduced. the animals 1st have to get used to their nissan 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 no sticks in 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 while to this fix is 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 bag. i saw the birds near a house at the river as they washed low. yes, he asked him for when i was out heard him go with the cab dialogue with the local community is important to biologist go. i say there help is needed to make the reintroduction process a success. i can pull up the device so that i mean we have to maintain this fixed as a habitat if we want to protect those equity. serious thinking, and that requires the dedication of people who live here. so it's because they have to monitor and ultimately put 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 habit that was probably the key that brought the numbers down to very little. and that's 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 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 beginning program using animals from these 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. 50 to 6 in the cause travel to preserve 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 vi piece be made 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 college and got has already been destroyed. thing was i can google iceland and his team visit local farmers each week. most like jamar desantos live by raising animals and staying everyone here and raises goats. i was, i have a lot of them just a few more than my friend. everyone has something to do with going to someone's they can best survive. and this drought written area of a cowboy on 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, to understand how the thoughts are connected. she 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 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 pro, to protect the environment. the proud to be from 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 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 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 experts about research and one of your knowledge, it's biological collection. and the way modern technology to make the indivisible is 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 neat to visit me. it 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, 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 the insects like into the buckling with a phone and to 80 percent alcohol which presents them for us. it's good enough that we're still insect groups including have in germany instead of hardly been studied gone. it's when we know next to nothing about the awesome projects like our trumps,

allow us to regularly find new species in these groups to show a bag with its meadows. and scott, to fruit trees is the ideal place for this kind of research. the district got state museum of natural history, nothing. and what was that? it began her usual process of analyzing the insects that had landed in the trunk using a microscope. she sold it them into species and size. they were just a few millimeters in size and belong 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 with spikes on the optimum, kinda and on say phones now with the walls that i had found a hot button,

fat. and so i began comparing it to all the newton species to see whether it might be something completely new and that no one had discovered yet kinda at the top. and that's what allows copeland 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 insect collections. it comprises nearly 5000000 specimens. 350000 of which belong to the order of hymen not threat. 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 thorough 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, 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 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 fits 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 that are showing a high level of detail. these are longer time the, the complex piece of digital technology will help unlock the secrets of the new was b c's. 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. let's 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 all be pleasant to use for laying eggs. and it's all in very high resolution. such discoveries represent lucky moments of biologists because many species disappear before we even know they exist. nothing. and what was that is determined to do my best to avoid that. she'll keep searching for the unknown right here on her doorstep.
