Can affect performance. And eternal archives storing data on d. N. A. And suspense is a way to create dramatic tension but in this film by alfred hitchcock. We have a fascination with fright and scary scenes can be strangely enjoyable. But in real life fear can become overwhelming even a sign of an exciting disorder we may see a young woman who shared his story. If youre anxious or considered weak the same if you have an anxiety disorder the assumption basically is that anyone with a Mental Health disorder is weak and that makes it hard to open up and say hey i have an anxiety disorder. And i still. Have that and i thought it was triggered by a specific incident when i was twelve i went to the doctor and they took blood from my back. That was so horrible that i fainted it was me it was the first time id ever passed out and thats when it started backing it was that he had asked how i was terrified of going to the doctor and i fainted at the doctor a few more times. And then when i hit puberty my anxiety expressed itself in other ways not just at the doctor but at the movies at school plays it got bigger and bigger social ill feel. On what it might. Happen again i mean i have a generalized anxiety disorder that means my anxiety is sort of free floating and it can knock me sideways at any time in the subway in a Movie Theater basically in any situation about panic attack on top of that i get panic attacks and i have a few phobias although they arent that severe fear of heights for example the fear of spiders and claustrophobia it all boils down to anxiety and the feel of. Them coped underneath but then when i watch a film i get immersed in it i see myself in the film and maybe not as the main character but im in it. And yet once in a movie there was a scene in an operating theatre that was pretty awful and. I closed my eyes after just the second that it quit saying it but then i had to leave because i thought i was going to faint. Before i spent the rest of the film in the bathroom it was hard to explain to the person i was there with friends that i said oh im not feeling well i dont like the film. I always had an excuse im saying im not in the mood i always had some kind of excuse when i kind of. It must be a good for us on the us for she been. Honest with him much speculation and im honest its hard when you feel you are abnormal are convinced everyone else is relaxing cool and youre the only one whos weak and afraid. As its yes calmed at the first step was that i made it to myself that i had a problem and going to a therapist. Dot com desk with that the next step was getting a diagnosis for the first time it felt like something tangible and anxiety disorder before that when i thought about it or talked about it i just say i have this stupid fear. Got the cards. I dont know if you can ever overcome an anxiety disorder im not sure that Something Like anxiety can ever really be cured i basically assume ill have it all my life but it comes in waves i get off on about psych thats life sometimes i have a good face and the anxiety doesnt last long. Quotes of it buries my anxiety levels are an indication of how things are going as good as and sought after and subside and if im not doing well and im overtaxing myself because i do tend to be something of a perfectionist then anxiety comes along and overwhelms me and forces me to pull the brakes on come to stop dont make me for recognizing that helps me embrace my anxiety because in fact its protecting me and im grateful for that by as yet and i just thats a common one pass on alt. When it comes to anxieties and phobias many psychologists say they need to be faced head on. Behavioral therapy can help people overcome these conditions are also wanted to see how it works. That big and hairy and they have eight legs. About ten percent of the people in germany find them scary including me. Im going to take part in a behavioral therapy experiment. At hagens Book University psychology professor and. His team treat people suffering from phobias confronting them with the very things theyre scared of theyre mainly in the realm of Virtual Reality. The main advantage is perhaps that the exposure can take place in the therapists office you dont have to go out or book a flight or collect spiders or climb a mountain you can actually experience the fear and work on overcoming it in the office. Before going virtual i have to meet a real tarantula its name is gandy. Though it doesnt look very peace loving to me. It starts to dawn on me what im in for my heart starts to race my hands feel icy cold i dont really want to get any closer to gandy later i still have to do the same test again to see if the Virtual Reality therapy has been effective if there he says my fear is a learned response and i can unlearn it. In exposure therapy its important to approach the situation in a different light first you have to grasp that the fear itself is not dangerous. That you can endure it and then you practice approaching the situation and staying with it and learning that the situation can be mastered that fear can subside. So does the therapy work im kitted out with a heart rate monitor a racing heart is an indicator of fear im still feeling skeptical. I dont the vi headset and im off. Level with the controller i can get closer to. The spider look small and harmless but it feels totally real and rafal thing i have to stick with it so the fic can subside. Where is that one above the table. Its so big. My hands are shaking and my heart is beating faster. So what its actually going on in your body when youre scared. The optic nerve alerts the limbic system to danger the hypothalamus takes over the body reacts the older is sent to the edge to produce a gentle ending cortisone or the heart speeds up the Blood Pressure rises more blood flows into the muscles her sweat erupts in a fraction of a second the choice is made to flee or fight our distant ancestors who were too bold were killed the too timid one says well we their descendants are a mix of lion tamers and scaredy cats but primal fears enjoy her even though we rarely have to fight for our lives so why do we still have such primal fears thousands of years on oil is an evolutionary psychologist. And the things to for norton im cool if you look at peoples fears they are looking through a window into our remote past ones they reveal what dangers existed back then. Would the. Real contemporary dangers dont figure among the phobias. Things that really threaten us with Food Poisoning our Nuclear Power plants electricity in the sockets you know how the hammer in your tool box guns firstly our fears hell from a very distant past. Poisonous snakes and spiders are rarely if ever a real problem in western europe for example still is there some point in having such fears it grows to guns in general terms they can make sense if theyre not too intense. But if they really mess up your life you should get treatment. But all in all theyre a helpful guide for life if there is usually something to offer as exist if nothing for our life would be in constant danger. Pretty good feel good. Care is more than an evolutionary relic it helps us remain alert it warns us and protects us. Back to Virtual Reality in claytons book after an hour or so i dont mind the virtual spider anymore even when it crawls towards me. But im on high alert but im ok. Im still feeling wired but ive gotten used to the situation so i bridge my first goal and i can head back to reality. Its really important to keep practicing even once the therapy is over you have to make the transition from Virtual Reality to reality and confront the real life situations as swiftly as you can and practice dealing with fear in a new and different way. For your you have to carry on facing frightening situations rather than avoiding them actively seeking them out so the fear does not grow again. As to that transition to the real world now i have to meet gandy again how will i respond after a first round of feet off the air if he really felt its a real surprise for those who are supposed to see. A cause. Or effect. Thats coming. All and my hands are very cold i was happy that i let the spy know walk over my handlers have gotten the spinning and im. Such a program after just one hour of Virtual Reality therapy that something i would never have expected. We asked our viewers on facebook what are you afraid of. Added to. The you are doing is afraid of chickens. Martina compass it is afraid of crossing the street in vienna. Welnick a saint louis is afraid of loud noises such as cunt fire and fun death. And Michael Lewis says hes afraid of things he can hear but not see. Seven jamiesons fear is about the future that one day human arrogance shortsightedness and greed will extinguish all life on earth. Next up we have this weeks viewer question. Its about the history of humanity and takes us back into the mists of time. We said water Lopez Granados from mexico wants to know. How old is human contact scientific opinion is divided. Its also divided on the question of what exactly sets our species apart. Is it the invention and creative use of tools. No other animals also find creative uses for tools. The answer is to be found in the human genome. Humans closest relatives the great apes we share more than ninety eight percent of our d. N. A. With chimps but roughly five million years ago human and chimp lineages are believed to have diverged. Our earliest ancestors pre man prehistoric man and early humans were a motley bunch thats why researchers tend to see the human family tree as more of a bush with many branches. The. Archaeologists are always on earth thing find indicating that our human ancestors were scattered all over the world from south africa to china and the balkans. But paleoanthropologists broadly agree that africa is the cradle of human kind and specifically ethiopia it was here that the oldest remains belong to the genus homo were found there two point eight million years old. Homo sapiens only evolved a few hundred thousand years ago the only living being capable of reflecting on its evolution. If you have a size question go to our website and send it in if we answer it on the show youll get our d. V. D. Featuring a lighthearted look at Albert Einstein most famous theories. The most important thing is to never stop asking questions. And old wives tale says that reading in low light is bad for your eyesight scientifically speaking thats nothing but a myth. But when it comes to the workplace can the right light make a difference. Some researchers are trying to answer that question. Come a light improve peoples performance at work that question is being investigated by scientists at the Technical University in cologne. The doctor and engineer who make up the Research Team are fascinated by the possibilities offered by light emitting diodes they can tune and concentrate the light from l. E. D. S. And easily control color and brightness. Ideal conditions for researching the effects of light on concentration and creativity. Quarter light be the key to more Effective Work practices. Does astonish through both the should the us donnish in thing for us was that we noticed an effect on behavior and cognition that was dependent on color temperature. And for and that was unexpected for this good that you would maybe expect a difference between sunlight and artificial light but color temperature also played a role. That discovery was made. In a standardized test fifty students had to answer questions the time allowed and the questions asked were always the same. Only the lighting was different. Whats called comma temperature the characteristic of visible light was carefully altered over the course of the experiment. The team also tracked medical factors such as pulse rate. The results shows of the subjects achieved different results when the research was changed the color temperature of the l. E. D. Worn white light boosted creativity and. Logical tasks on the other hand were better solved in cold white light. So cold white light is better if youre taking an exam. And if you want to be creative turn on a warm white light source most of the music i was. Students at a university dont spend all their time on the theoretical side of research they also have to develop prototypes of new Electronic Devices themselves. With a bit of help from a local company some of them built on light control unit. And then they developed a nap to control the color of the light at a workstation or in the living room. So according to the users task or preference the lights can be changed seamlessly from bright white to bluish reddish or greenish town. In future the engineers plan to design an even more refined controlled system they want to mix artificial lights with the prevailing daylight to provide constant ideal conditions. Every day people around the world produce a huge amount of digital data. Base so much of it that storage is becoming a concern. Weve paid a visit to a researcher whos developed a new solution. If you head north out of london towards cambridge after eighty kilometers you reach. The village is home to the european bio informatics institute. Nick goldman is working on ways to store Digital Information so itll last for a very long time. Current Storage Systems disks and tapes up. Prone to fail and degrade goldman has harnessed d. N. A. For a test of his new system he chose for documents. A photo of the institute. A classic text about genetics. An excerpt from Martin Luther kings famous speech. And the text of war one hundred and fifty four shakespeares sonnets. The idea was born in a hotel bar in hamburg in germany where i had been a to meeting all day with my colleague you and me where we had actually been discussing how our institute would store Genetic Information on computers and the cost of doing that and at the end of the day with german beer we were talking about other ways maybe you could from ation and the inspiration initially was to think of a way that would be less expensive. And between ourselves the joke was that we realized that you could use d. N. A. Itself as a storage medium as well as the source of the information we wanted to store. Its an amazing idea to engineer d. N. A. To store data. First goldman and his team had to develop a code to translate the ones north of digital data into a ts and g. s the four letters that correspond to the basic elements of d. N. A. And they had to break them up into manageable chunks of d. N. A. A machine a d. N. A. Synthesis machine then actually builds them. Before items were translated and transferred into artificially created strands of d. N. A. A biological hard drive. Its very very small so you can store a lot of information in a tiny volume of space. Another interesting advantage is there will always be a reader for d. N. A. The machine to read it the specific machine to read it will change we invent new machines every few years for reading d. N. A. But because of the implications for human health theres always going to be a machine to read it. The next step in the experiment was to see if somebody else with the right equipment could decode read the d. N. A. Files and translate them back into the originals production of the high quality stuff. And the recipient was vladimir banish a geneticist at the European Molecular Biology Laboratory in hyderabad. Here the d. N. A. From hinkson had to be processed is a complex business and expensive at least for now. But the experiment was about establishing whether this kind of writing storing and reading of data actually works. What was coming from the he didnt tell us saudis doing which is hindsight is still saying it was good but of course the final it told us so what we did it was very exciting. Could this be a reliable and feasible method of storing lots of data for a very long time. Currently you have to pay Twelve Thousand dollars to archive one megabyte of data in d. N. A. Then itll cost a further large sum to have it read by a sequencing machine. Instructions and needed to read it correctly. It took the team in heidelberg two weeks to read the data and reconstruct the originals. But they succeeded. The speech the sonnets the photo and the genetics text all reappeared. That was a pretty impressive achievement. But the technology is not yet ready to be deployed in every office or archive. We need the synthesis of d. N. A. To get a lot faster and a lot cheaper maybe a thousand or ten thousand times cheaper than is that i mean that sounds very off putting. And you might think it would take a very long time but in genome science we very quickly got used to the idea is that improvements very large improvements come very quickly. Tiny specks of d. N. A. Can store vast amounts of information all the digital data in the world could fit into a few meters. Or.
