oh, those engine vs you belong to the 77 percent because i just got in 65 last last goals. and here's 3 reasons why. 1115. we're here to help you make up your mind to the topics. i'm much up to you from campbell topics, the new culture financial team. and let's say quote the 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. instead of a fast amazing 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 $250.00 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. are 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 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 post the res. so it essentially stands for the entire group is a counselor 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 tend to google expedition in colonial german east africa. he attends a girl expedition is still considered one of the most successful vertebrate poly

until naji expeditions because of the variety of dinosaurs in the 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, a whole month from buttons, natural history museum. the excavations took place between 19091913 at 10 degrees of hill and south east and tons in a as one of the expedition latest kept to general jim and patty ontologies, the young inch, understand that the though the end of this, there's a postage right at the beginning, where he writes that ideally they would like to tear down the entire hill on in the style. and in the end, they took away an incredible 250 tons of world most fail flushed. and it's hard to imagine how they actually moved it. no,

we need to remember people moved it by 100 ducks. i'm a homeless around 500 local people. took part in the excavations thinking up the petrified fossils and plucking 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, 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 could be expected. so 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 tons of fossils. over the course of 4 years. from there, the cargo was shipped to belen a. yeah, this year number the she and i'm on the phone really good. you can do so.

expeditions to that out. who says saw dog 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 okay, if it didn't affect her just ok. we're doing this kind of specialized this by is already kind of walk ok. but the extra doing it was, was standing by and i see that 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 of the last thing. legacy do you have in general paula from the fallback still has a dinosaur named after him?

the diesel to source letter for becky. and then that's the issue of compensation. so you have now decided to kind of use. i'm under the if you to just some of them say, okay, we need to do we need, we need to be a bit advanced box. but us, so we have 7177 member as well as 8. okay. now we don't need to be this this box, but there just to the government, the government government should be paying for some money to the communities for protecting these that are the names about which actually belong to this area often double is, are headed to most of the tend to grew fossil is currently lined the lot brent find 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. 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 gob steps found a degree in abundance in the area. and it grew 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 floor. and 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 french 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 for sue and wildlife research? here veterinarian key to switch normally perform the c t scans. i'm living

breathing animals. not a 150000000 year old phones and 100 year old barrels. behind a wouldn't let a nails la via the fossils 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 your remnants from the smooth dice and low to source goals. that's quite special for us because we only have a few sco remains from these dinosaurs zone. when we find these, it's under joel even still has a 2 senate that's that's the root here on the other piece of contains smaller replacement ones. apparently these dinosaurs changed that piece of issue and you

are, these are strict moses, 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 barrels will deliver further insights into the prius. start contents on gym and colonial history. via owns it. any dinosaurs running the planted today, the most likely reason is an asteroid, striking this around 66000000 years ago, also wiping out countess other living beings imagines and disappear in subspace. ease is inevitably influenced by environmental factors, changes in local conditions, evidently having an impact on the fi of science 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 glow was finding a made is no easy mountain. nowadays. thoughts thanks to our ever brought to cities, female blue ones comp fly, so they rely on their 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 these different run 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 mains. when it was docs and male, found the female every time that on the street night could sions only if we face smile managed the artificial lights likely tassel,

the beetles. so let's turn off the lights more often and give the glue. when some private time the blood is read, why are they 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 back at the ends to understand the function and benefits of these ringlets 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 plains 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 aerodynamic 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 wing lips can ascend quicker while using less fuel than an aircraft with the same thrust and wing span, but no winked of devices on long haul 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. 10 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 go to movie really features 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 bound to discover how he really lose the last may i have a kind the only other blue mccall leasing rio de janeiro. that's where the 6th is. mccaul used to be at homes 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 speakers because and right now they're demanding their breakfast, mixture and visuals spread and see if it's that

as similar as possible to food in the wild. once they eating a little bit while shoes, they able to put together guide books and it gets 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 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 if it keeps 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. this fixed costs are 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 and when i was on the battery, i saw the birds near a house at the river as they wash slow. yes. he asked and but when i was out heard him go with the cab 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 the device 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 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 animals return is thanks to a complex breeding program that was supported in part by the brazilian government. a german non profit association led to 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 them, 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 for everyone has something to do with codes. you can go and say

can best survive. and this throughout written area of campbell, as 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 and now the proud to be tried to speak to me, call the pro, to protect the environment, to proud to be from catching. got 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 theses science teaching that so canada sees . we now know that there are 4 types of 2. well, for example, to southern dropped the most size or off the ridiculously, to off and the northern to run on a slightly smaller scale. there's a nice, b, c sound up in germany. this is a story about an exciting find that surprised even the experts about research and one of units knowledge, it's biological collection and the way modern technology to make the indivisible

bits of a seated read scans. many things, but never had anything. this spectacular coming up miss scott, yvonne, 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 a if needed 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 tense function is insect tops enabling 1000000 and what was it to record? how the species had changed in number on composition or 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, but they phone and to 80 percent alcohol, which was this them for us is good enough. there was still insect groups including

haven, gemini, 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 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 trap using a microscope. she sold it them into space, sees in size. they were just a few millimeters in size and belong to a family of last. but then she found something she had never come across before. the except lawson 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 known as looters. i have had a row to spikes on the optimum, kind of on so far. now with a was that i had found a hot and 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 on these and wasps, the inch monitors compare the tiny was 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 press. one says he will after this is what surprised us is that such a striking species could be found in gemini, visited the isaac. this is the only known species of power. so toyed was with this particular ro stolen to the end of its abdomen nights. and this is there a hundreds of thousands of species houses and then from that this feature has never been seen before us. it's never been discovered. when done, they could be the sort of tomorrow i'm gonna 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 kathy 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 needs of equipment which were unable had to do just that. it's

a high throughput x ray micro c t scanner is on the 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 to materials research, for example, produces 3 dimensional images of small samples showing a high level of detail. these are longer type the, the complex piece of digital technology will help unlock the secrets of the new wasp species. it's a special form of computer to come up with a the can reveal the inner workings of specimens that have just a few mike, for me to is in size. let's see, i'll let it 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 repository used for laying x, and it's only 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 the that's it. so this episode of tomorrow today, your d w sign show, see you next time and stay curious by the the
