pursuing her own visions. no other woman got some close to. life and death with the child. starts july twenty first on d. w. . h. into the science show on d w one come to you tomorrow today coming up. a look back in time to a flying reptile as big as a truck. a critical view of virtual reality poised to change our world. and we celebrate the artist's return to switzerland and the citizen scientists was stalking them.

but first we head to the dark and mysterious world of the deep sea. only around five percent of the world's oceans have been explored their home to a vast range of creatures from delicate jellyfish to terrifying predators. off the coast of northwest in africa a team of researchers has discovered a gigantic structure on the sea bed built by corals. over this amazing underwater landscape is being researched by a team from the university of braman a reef four hundred kilometers long and up one hundred meters tall. it was created here in the atlantic off the coast of mauritania in west africa by cold water corals. the minute they live in great depth in absolute darkness they rely on currents to deliver tiny particles of food for them to observe. often when those particles are plankton which drift like snowflakes

through the oceans the supply at those depths is meager so cold water corals grow slowly not more than fifteen meters in a thousand years. still the team have discovered astonishing coral formations. the aphelion found very many reefs especially in the atlantic with coral mounds some more than three hundred meters tall. and that's as tall as the eiffel tower all the t.v. tower and berlin if that's really big. absolute say you will give it up. to find out more about how the reef may mauritania developed cloudy again back and her colleagues collected samples of fossil coral from different layers they determined that it had been growing for a million years but then it stopped. side to begin.

the end of the ice age ten thousand years ago there's been no new coral growth in this area off areas that coral could not survive because of very low levels of dissolved oxygen in the water. and on the other hand video footage shows that there has been a recent colonize ation by coral. still the conditions are so bad that the coral is not able to create new reefs needing a lot of its. scientists suspect that parts of the world's oceans with very low levels of oxygen will continue to expand putting pressure on deep sea ecosystems in conjunction with climate change. one of the most common species of cold water coral is lost. its branching skeletons form frameworks and eventually extensive reefs.

these colonies are home to starfish sea urchins lots of different fish and countless other kinds of animal. windy and our cold water corals are called the bioengineers of the deep under many species of fish including ones that are commercially fish use these coral reefs as boring grounds as a place to feed and also a shelter so they play an important role in shaping the deep sea ecosystem in the t.c. researchers have identified four thousand six hundred species that live in cold water coral reef ecosystems that each expedition uncovers more but how cold water corals reproduce is still something of a mystery. the world down there in the depths is astoundingly diverse and puzzling it would be terrible if it were lost before we managed to understand it.

from the deep sea we head up into the air with a dragon. these flying creatures are certainly trendy nowadays just look at the popularity of the game of thrones series jenkins may be a purely mythical species but an excavation in romania has an earth something that comes remarkably tell us. that gigantic skeleton being assembled here is about sixty six million years old. this bones belong to a terrorist or an extinct flying reptile this is the world's largest known specimen and it's being reconstructed in its entirety here the spectacular find was identified by romanian geologist and paleontologist matches for many and he has found many important fossil reptiles but at first he couldn't believe what he'd come across. this was the main discover the truth to realize why. the fools

was. there we did what we knew before the results were so messy the might might breed didn't accept it as such it's not. until recently experts thought pterosaurs had a maximum wingspan of around ten meters this one measures it's more than fifty meters. that's about as long as a truck it was a giant creature even in an age of large reptiles. the fossilized bones were first spotted protruding from this cliff side in transylvania romania in two thousand and nine. salvaging them was a complex undertaking. i'm on to other star for is a paleontologist an experienced fossil hunter. he was part of the excavation team and is well aware that the chances of finding pterosaur bones are slim. they're

much more fragile than dinosaur bones. as the oysters technology just been exposed to very thin walls with hardly any organic material inside them just the spongy tissue that was ninety percent but when i was used overall weight and therefore increased its flight capability that in the he cut so very likely the bones. here in the dinosaur museum in new talent are varia the giant pterosaurs reconstructed skeleton goes on display for the first time. how exactly did these creatures move on the ground it's not known for sure but they probably got around on all fours with their wing membranes neatly folded up on the sides. it's also not clear how they managed to become airborne some experts believe they needed to take off from an elevated point rather like a. hang glider.

but it's also possible that larger specimens didn't fly at all because they didn't need to escape from predators. the sensational find has raised many fascinating questions for paleontologists around the world. and drawn quite a crowd to the dinosaur museum here in. all these really looking scenes made with hollywood's most cutting edge technology where is it all headed. well he says they experiencing an augmented world through virtual reality glasses rose tinted otherwise. technology giant google is banking on virtual reality of the r.

and has entire divisions developing concepts it's even converted its renowned google earth maps into virtual reality format. that allows users to explore the entire planet in three d. . dominic casey is ahead of the project the swiss graphics wizard leads a huge developer team at google in california in his free our world those with a head for heights can even land on a new york skyscraper like superman and peer down into the abyss. the point of all loose. and he thinks we are as one of the platforms that will become game changers exerting huge influence like smartphones laptops and computers did we're trying out what kind of opportunities it offers google's mission is to enable users to utilize all the world's information. and we are off of enormous potential for that. case i once worked for

the legendary pixar studio he knows the thrill is what counts in california people in california developed for the movie industry using light color sound and animation can be used to tell stories and create virtual experiences which people can immerse themselves in a different. place because also taking an active interest in via. one of the leading global producers of v r headsets it sees as a new benchmark which could replace the computer monitor facebook founder mark zuckerberg has big plans. we want to get a billion people on virtual. video for a billion users even futurologist steven seacrest isn't certain of that kind of take up but with most global players now in the race change is afoot.

with lots of money or investing heavily in the market they're under pressure to come up with the next great game changer there's nothing revolutionary going on with smartphones anymore but people have high hopes for the arch and we can be sure that pressure money and a passion for innovation are driving the technology forward but at the end of the day it's the practical applications that will be decisive innovation only makes sense if users accept it. back in a couple of years ago or mentored reality in the form of poker mongo took the world by storm or mentioned reality allows users to interact with virtual objects in the real world but its uses go far beyond games. so its industrial company has been experimenting with augment reality. is wearing what's called a hollow lens that combines the real world with the virtual.

virtual projection of a machine manufactured by be embedded within real space. that can be physically explored interactively controlled using a control box and finger movements the system offers a totally new opportunities. it's good for training combining the real with the virtual we can completely transform occasional training and we can approach industry exhibitions in a totally different way we don't need to take in time machines along with us we can plan carefully what we want to preserve physically and what virtually but we're only just beginning to grasp what it all means for us. as working together with software specialists from the net etc company the technology also works on mobile devices and it's becoming increasingly easy to create virtual log. as you know it's

much easier today because the hardware producers effectively take it out of our hands are ever more developer tools that do the mathematical work for three d. object displays. nowadays it takes just a morning or one day to devise a small application are going to clean up a pretty. hollow lens is still in development for now but augments of reality is bursting with potential. the latest generation mobile phones and systems come with a r pit's already installed. virtual interactive world already taking shape on our mobile devices. what will the future be like as we face an ever increasing onslaught of information. video are just peachy matsuda envisage this possible scenario. i mean we're already exposed to massive sensory overload people can't even keep up with emails and the overload will grow with augmenting reality you're out shopping say

looking at what's on offer and suddenly an acquaintance pops up in the past you could act as if you didn't see them so now you have to acknowledge them because your friends on facebook i think that it leads to is more precious more social interaction the necessity to process information and i think that's one of the main challenges on and it means the technology will be used selectively but not in blanket deployment of god and operate meet it because at least offering somewhere to hide from the noise. the nineteenth century mathematician ada lovelace is credited with writing the first computer code in history long before computers in the modern day sense existed however the programming pioneer took a dim view of machine intelligence. but nowadays we don't need so i thought. rhes like westworld to convince us that algorithms have become

a lot smarter since lovelace's time and more disturbing. someone's reaching for their smartphone and going online purrfect. because. in fact i already know how. that's a dana she's twenty six years old lives in cologne and comes from seguin she trained to work in office communication management but she's now studying business . she told me everything voluntarily. but i know even more about her i know her biggest secrets how well i don't want to reveal everything but i'll tell you this much i collect data i am facebook's data base. i know what edina likes the wrapper clue so she's a fan of labor crews and football club and she enjoys working out. i know which

posts she likes the one she shares with her friends and those she comments on who she sends private messages to and what she writes in them. i can watch her away from facebook to edina has my location service activated i know when she goes whack and i know that he spends her time all. three times a week she uses the wife i have a particular cafe she probably works that maybe it's how she finances her studies or something else. a movement profile also tells me which other facebook uses around her and two she hangs out with even in the real world that's what college. was. found this guy spends practically every night with her you must be her boyfriend but every now and. again another profile comes up even at night i recognize him.

her other apps also give her secret away. this is where edina likes to shop which she prefers to log on with her email address all with her facebook account it's an easy decision just one click and idina can shop to her heart's content and i can collect even more date information like this. i dinna no longer orders wine instead she buys smoothies frozen pizza and jars of pickled gherkins. and when i show her a baby photo from her friend on her facebook app she pauses slightly longer than usual. so what could all this mean. well her boyfriend has no idea but do you know are you coming. nor does her

colleagues. many people are worried about what happens to their data in social media networks. we asked you do you share everything on facebook. asher bug or too many of those peer rules he says he won't post anything from his workplace little personal information and no family photos because those the preconditions for living in peace with facebook. chris raised only she has good things and educational things on facebook. she doesn't want the world to know anything too personal or find out about bad experiences. and could research the work levere also posted an opinion saying i contra all my data for privacy reasons . so i keep saying to myself.

still we're glad that the parents of these cute babies didn't keep their pictures to themselves just look at them testing those lemons. one of our viewers observed a reaction like this in his nephew he's been a deer affronting not in ghana and he sent in a question about it. why do babies put everything in their mouth. no matter what they see in front of them they want to suck it lick it all chew on it even the camera filming them could it be that they're simply hungry. no they don't want to eat the objects they want to examine them and babies can do that best with their mouths. in newborns the highest density of sensory receptors cells is on the tongue. other senses like seeing hearing

smelling all feeling are not so well developed in babies. the ability to pick up a small object between farm and index finger called a pincer grasp is a developmental milestone at around nine months of age. until then a baby's tongue and lips get most of its information about the shape and texture of objects. researchers believe that babies have an image of what they have in their mouth and may even recognize it by sight later. the mouth not only provides information about the world it of course also helps to still hunger and thirst and satisfy the desire for intimacy. the so-called oral phase lasts until. a child is about two years old exploring their surroundings

with their mouths helps babies develop a personality the mouth is their gateway to the world. but only very few made it. do you have a science question that you've always wanted answered we're happy to help out send it to us as a video text ovoid smell if we answer it on the show we'll send you a little surprise as a thank you and just ask. you find as i did a dot com slash science or drop us a line at g.w. under school site tech on facebook d w dot science. now we head back to the water in switzerland where alters are making a comeback the dextrous animals have many clever habits for example they sleep holding hands so they don't drift away in the river. scientists have been watching

them. through. a camera trap took this footage of an alternate the are a river in switzerland. with the rest of the family. it takes resources and time to capture such images it's hardly feasible to set up traps across large areas. but there are other ways to find out where i often saw. conservationists of set up a project to monitor the animals here in central switzerland it's headed by every new find backa bit tryst paris phil is one of thirty six volunteers involved in the effort. pulses leave traces often in the shadow of a bridge. or smells rather fishy bit of angst and he looks very fresh. off his mark that territory by leaving piles of excrement that say this part of the river belongs to me. the piles help the researches track down the

animals. alters could well be living in this stream to buttress paris phyllis going to check the structure for to once a year. she already keeps track of divas and is thrilled the authors might show up to. one may insist but for me it's a real highlight when a species reappears colm toibin especially when it was basically our fault that it disappeared in the first place author's left because the conditions weren't right for them anymore. although switzerland had to catch the ultra protected species none had been sighted in the wild since the one nine hundred eighty s. these ones live in a zoo. one theory is that toxins in the environment had rendered wild as in fact. it's exciting that several baby up to have now been seen in the region

a few authors are known to be living in the come to terms of solitude on and bam but i'm more and where. volunteer ata trackers have already been signed up in the areas marked in red. further south. is looking for those telltale signs on the banks of the river counter. this might or might not be relevant evidence but the volunteer tracker takes a photo just in case. this stretch of record was cleaned overnight shift as it's called more than a decade ago the environment is now at a friendly. the positions the river was renamed should we have conducted regular inspections and determine that six species of fish have returned home also it's nice to see all these various kinds of habitats or it's good for me as an angler it's also good for the authors. some mindless don't agree they say otters

eat too many fish. the project is not only about observation it's also about selling the opto to the public and that includes hostile anglers. it's also about explaining the office behavior and possible impact on fish stocks. if. they could of course of the starters will affect some fish populations that's how it is with predators all but i can play it but i don't think of devastate them martyrs can only thrive where they can fish sustainably if there aren't enough fish hunting gets to be hard work and the otters move somewhere else. to. help if not in class that. the main threats to fish pollution and rising water temperatures really not your ration of records certainly relieves the pressure on them that's also good for authors the question is if humans will welcome more of them and their midst.
