But first we head to the dark and mysterious world of the deep sea. Only around five percent of the worlds oceans have been explored their home to a vast range of creatures from delicate jellyfish to terrifying predators. Off the coast of North Western africa a team of researchers has discovered a gigantic structure on the sea bed built by corals. This amazing underwater landscape is being researched by a team from the university of braman a reef four hundred kilometers long and up to one hundred meters tall. It was created here in the atlantic off the coast of mauritania in west africa by cold water corals. The minutes they live in great depth in absolute darkness they rely on currents to deliver tiny particles of food. For them to observe all of. 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 metres in a thousand years. Still the team have discovered astonishing coral formations. Harm sions aphelion found very many reefs especially in the atlantic with coral mounds some more than three hundred meters tall. Thats as tall as the eiffel tower the t. V. Tower and berlin if thats really dig. Absolute was a year. To find out more about how the reef may mauritania developed cloudy ive been 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 theres 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. 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 worlds 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. As windy and our cold water corals are called the bioengineers of the deep many species of fish including ones that are commercially fish use these coral reefs as spawning grounds as a place to feed and also a shelter so they play an Important Role in shaping the deep Sea Ecosystem in netty sea researchers have identified four thousand six hundred species that live in cold water coral reef ecosystems and 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. These bones belong to a terrorist or an extinct flying reptile this is the Worlds Largest known specimen and its being reconstructed in its entirety here the spectacular find was identified by romanian geologist and paleontologist matches for a very near he has found many important parts for reptiles but at first he couldnt believe what had come across. This was the main discover to attribute to real. What that feels was so. That we thought what we knew before us was so big that my might believe didnt accept it as such. Until recently experts thought pterosaurs had a maximum wingspan of around ten meters this one measures more than fifty meters. Thats 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. Tremont other star for is a paleontologist and experienced fossil hunter. He was part of the Excavation Team and is well aware that the chances of finding terrorists or bones are slim. Theyre much more fragile than dinosaur bones. As he always has the clock you just see it in its own good very thin walled with hardly any organic material inside them just the spongy tissue that was ninety percent bus who used overall weight and therefore increased its flight capability that in the here. So very lightweight bones. Here in the Dinosaur Museum in us mil tile into the area the giant pterosaurs reconstructed skeleton goes on display for the first time. How exactly did these creatures move on the ground its not known for sure but they probably got around on all fours with their wing membranes neatly folded up on the sides. Its 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 its also possible that larger specimens didnt fly at all because they didnt 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. These really looking scenes made with hollywoods most cutting edge technology. Where is it all headed. Experiencing an augmented world through the actual reality glasses rose tinted or otherwise. Technology giant google is banking on Virtual Reality of the r. And has entire divisions developing concepts its even converted its renowned google earth maps into Virtual Reality formats. It allows users to explore the entire planet in three d. Dominic a is ahead of the project the swiss graphics wizard leads a huge Developer Team at google in california in history our world those with a head for heights can even land on a new york skyscraper like superman and peer down into the abyss. Point of all those. Things we are as one of the platforms that will become Game Changers exerting huge influence like smartphones laptops and computers did were trying out what kind of opportunities it offers googles mission is to enable users to utilize all the worlds information and 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 have a friend. Because also taking an active interest in via. One of the leading global producers of the headset it sees as a new benchmark which could replace the computer monitor facebook founder Mark Zuckerberg has big plans. We want to get. For a billion users even futurologists steve isnt certain of that kind of take up but with most Global Players now in the race change is afoot. With lots of money are investing heavily in the market theyre under pressure to come up with the next great game changer theres nothing revolutionary going on with smartphones anymore but people have high hopes. And we can be sure that money and a passion for innovation are driving the Technology Forward to the end of the day its the Practical Applications that will be decisive innovation only makes sense if users accept it in. A couple of years ago mentored reality in the form of go took the world by storm. Reality allows users to interact with virtual objects in the real world but its uses go far beyond games. Swiss Industrial Company has been experimenting with mentored reality. Is wearing whats called a hollow lens that combines the real world with the virtual. Virtual projection of a machine manufactured by being embedded within real space. It can be physically explored interactively controlled using a control box and finger movements system offers totally new opportunities. Its 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 dont need to take entire machines along with us we can plan carefully what we want to present physically and what virtually but were only just beginning to grasp what it all means for us. Here is working together with Software Specialists from the net sector a company the technology also works on mobile devices. And its becoming increasingly easy to create virtual objects as you feel its much easier today because the hardware produces effectively take it out of our hands are ever more developer tools that do the mathematical work for three d. Object displays for nowadays it takes just a morning or one day to devise a small application of. Clean up the. Hollands are still in development for now but augments of reality is bursting with potential. The latest Generation Mobile phones and systems come with a r pits already installed. Virtual interactive worlds already taking shape on our mobile devices. What will the future be like as we face an ever increasing onslaught of information. Video artist Keiichi Matsuda envisage this possible scenario. I mean were already exposed to massive sensory overload people cant even keep up with emails and the overload will grow with augmenting reality your out shopping say looking at whats on offer and suddenly an acquaintance pops up in the past you could act as if you didnt see them now you have to acknowledge them because your friends on Facebook Think that it leads to is more precious more social interaction the necessity to process information and i think thats one of the main challenges. All those other means the technology will be used selectively but not in blanket deployment of all around the of admits its a cult at least offering some words of hard truman 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 dont need sipho series like westworld to convince us that algorithms have become a lot smarter since lovelaces time and more disturbing. Someones reaching for their smartphone going on line purrfect. Place where. In fact i already know how. Thats the dena shes twenty six years old lives in cologne and comes from seguin she trained to work in Office Communication management but shes now studying business. She told me everything voluntarily. But i know even more about her i know her biggest secrets how well i dont want to reveal everything but ill tell you this much i collect data i am facebooks database. I know what edina likes the rapper. Shes a fan of labor couzin 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 where and i know where she regularly spends her time. All three times a week she uses the wife i have a particular cafe she probably works that maybe its how she finances her studies for something else. And a Movement Profile also tells me which of the facebook uses are around her and who she hangs out with even in the real world thats what college. Was. That 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 will i recognize him. Her other apps also give her secret away. Because this is where edina likes to shop which she prefers to look on with her email address or with her facebook account its an easy Decision Just one click and idina can show up to her Hearts Content and i can collect even more date information like this. I dinna no longer orders wine instead she buys smooth things frozen pizza and jars of pickled gherkins. And when i show her a baby photo from her friend on her facebook app she poses slightly nombre than usual. So what could all this mean. Well her boyfriend has no idea again 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. I should bugger too many of those peer rules he said. He wont post anything from his workplace little personal information and no family photos because there is the preconditions for living in peace with facebook. Chris raised only says good things and educational things on facebook. He doesnt want the world to know anything too personal to find out about bad experiences. And research the work levere also posted an opinion saying i contrail my data for privacy reasons so i keep some to myself. Still were glad that the parents of these cute babies didnt keep their pictures to themselves just look at them testing those lemons. One of our viewers observed a reaction like this in his nephew hes been a do it from tim a 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 theyre simply hungry. No they dont 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 receptor cells is on the tongue. Other senses like seeing hearing smelling or 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 babys tongue and lips give it 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 socalled 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. Wide and even paid to. Do you have a science question that youve always wanted answered it were happy to help out and send it to us as a video text over as well if we answer it on the show well send you a little surprise as a thank you can i just ask you. To find as i did of you dot com slash science or drop us a line at d w underscore site tech on facebook d w dot science. Now we head back to the water in switzerland where artists are making a comeback the dextrous animals have many clever habits for example they sleep Holding Hands so they dont drift away in the river. Just scientists have been watching them. Through. A camera trap took this footage of an alternate the arm or river in switzerland. With the rest of the family. It takes resources and time to capture such images its 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 its headed by every new find backa bit transparent as one of thirty six volunteers involved in the effort. Pulses leave traces often in the shadow of a bridge. In. The smells rather fishy sitcoms 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 beavers and is thrilled the authors might show up to. What may exist for me as a real highlight when a species reappears boy and left especially when it was basically our fault that it disappeared in the first place authors left because the conditions werent 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 autos in fact. Its exciting that several baby optos have now been seen in the region a few autos and known to be living in the come to terms of solo tone and bam but im more and where. Volunteer author trackers have already been signed up in the areas marked in red. Further south from space it is looking for those telltale signs on the banks of the river calmed. This might or might not be relevant evidence but a volunteer tracker takes a photo just in case. This stretch of river was cleaned over in a church as its called more than a decade ago the environment is now out of friendly. That this is the river was renamed should we have conducted regular inspections and determined that six species of fish have returned home also its nice to see all these various kinds of habitats or its good for me as an angler its also good for the also has. Some mindless dont agree they say otters eat too many fish the project is not only about observation its also about selling the opto to the public and that includes hostile anglers. Its also about explaining the office behavior and possible impact on fish stocks. Of. Their daughters will affect some fish populations thats how it is with predators all but i can play it but i dont think theyll devastate them martyrs can only thrive where they can fish sustainably if there arent enough fish hunting gets to be hard work and the otters move somewhere else to. Help pay for the class that. The main threats to fish pollution and rising water temperatures really not sure ration of records certainly relieves the pressure on them thats also good for authors the question is if humans will welcome more of them and their midst. Next week we look at the astonishing capabilities of this truth. In winter they shrink their body size to get by with less food even their bones get smaller and they regress in spring. Medicine learn from shrooms. More on that next week make sure to join us see you then cup i. Move. To. Enter the conflict zone with tim sebastian.
