WASHINGTON (VR)— I know what you're thinking, a frogcicle will never become the top flavor at Baskin Robins, but for the Alaskan wood frog the genetic trick has become a very important survival trait. What the frog does, according to Don Larson, a Ph.D. student at Fairbanks, is dig a shallow hole near ponds where it breeds. After the hole fills with water, it will wade in and wait until the water freezes. This trick allows the wood frog to freeze up to 60% of its body, so as to reduce calorie consumption, and allow it to survive until the Spring thaw.
"So, when we say about 60-70% of their body water's frozen, the other percent is the water really inside their cells. So, it's everything around their cells that's freezing." Larson says that wood frogs not only practice their own form of cryogenics, but practice a form of camouflage to avoid predators while they are frozen. "They make sure to hibernate under leaves so they're pretty well covered, and I can tell you from my own experience that these guys are very, very hard to find." Mind you, it's not just a petal or two hiding them. They are hiding under leaves and buried under snow. Larson once spent two weeks raking, hunting for frogs, only to find two of them. That's a pretty bad payoff for 196 hours of work. It's even worse, when Larson estimates there were at least ten times that number available to be found. Larson found that the frogs were able to lower their body temperature as far as -20 degrees Celsius without harm to their bodies or their cell structure. "We have some evidence that they might be able to go even lower than that, but the thing that tells us is they're very hardy, and able to survive these conditions very well is we didn't see any wood frogs die." The wood frog is not completely unique in its ability to freeze, thaw, and walk away. There are some insects who've shown this quality as well as the Siberian salamander. The key to the survival of the wood frog may have to do with glucose... more at the audio link. Source: Voice of Russia - US Edition

Aggression in dogs: New study aims to 'bust some myths'

Aggression in dogs: New study aims to "bust some myths"
.Subscribe
Academics at the University of Bristol’s School of Veterinary Sciences have been investigating dog aggression towards people with a survey of UK dog owners which has been published online in Applied Animal Behaviour Science. Dr Rachel Casey is Senior Lecturer in Companion Animal Behaviour and led the research. VOR's Tim Ecott asked her what had prompted the survey.
"Aggression is a big public health issue," Dr Casey says. "People have even been killed by dogs, so it's a serious problem for people, but it's also a welfare issue for dogs, because it they're showing aggression, it's likely to be because they're feeling stressed in their environment. "We wanted to look not at serious aggression such as biting, but at any sign of aggression, such as barking or lunging." What did you find? "We asked about aggression in different situations. Are dogs generally aggressive or in very specific situations? We asked owners about the dog's behaviour in the family, out for walks, and when people visit the household. The results varied quite a lot between the contexts." "It tells us about the behaviour, not why the dogs are doing it. It's a baseline." There's a danger that these findings will be taken up by people who think that dogs should be more controlled, or vice versa, that it's only a small number of dogs that are aggressive. "Like any stats, you can argue them in any direction. But we're interested in information. At the moment, people denigrate all dogs, or certain breeds, and we wanted to find out much more detailed information to bust some of the myths." "We looked at breeds, but also owner age, training, gender, gender status and so on." Do you think that people like the idea of having a dog but don't really know how to train or bond with it in an increasingly urban society? "It's really important to get across to everybody before they get a dog to really think about it. Not just the financial and health requirements, but also the behavioural requirements -dogs have quite a lot of needs; every dog will need exercise, mental stimulation, lots to do during the day. So everybody who's thinking of getting a dog needs to address very carefully whether a dog is suitable for their household and lifestyle." (Voice of Russia) The survey, background The study, led by academics at the University of Bristol’s School of Veterinary Sciences and published online inApplied Animal Behaviour Science, investigated the occurrence of dog aggression towards people with a survey of UK dog owners. Nearly 15,000 questionnaires were distributed to dog owners of which 4,000 were returned and used in the analysis. The researchers found that aggression towards unfamiliar people was reported more commonly by owners than aggression to family members. Nearly seven percent of owners responded that their dog barked, lunged, growled or actually bit when people came to the house, and five percent reported these behaviours on meeting people when out on walks. In contrast, about three percent of dogs were suggested by owners to show aggressive behaviour towards family members. The study highlighted that the majority of dogs showing aggression do so in just one of these situations. This indicates that the common tendency to categorise dogs as either generally ‘safe’ or ‘vicious’ is a misconception, and that most dogs show aggression as a learnt response to particular situations. The study also compared the characteristics of those dogs reported to show aggression with those which had never done so. It was revealed that factors such as training classes attended, type of training method used, the sex and neuter status of dogs, the age category of owners, and the breed of dogs were all associated with the occurrence of aggression. Interestingly, different risk factors were found to be significant in statistical models examining aggression to family members and unfamiliar people. This suggests that different factors are important in the development of aggressive signs depending on the situation. The research also highlighted that although general characteristics, such as breed type, are significant risk factors across large populations they explain only a small amount of the overall difference between aggressive and non-aggressive dogs. This suggests that it is not appropriate to evaluate the risk of aggressive behaviour in an individual dog using characteristics such as breed type. (University of Bristol) Source: Article

How molecules are a lot like birds

Emory chemist Jay Goodwin was featured in an interview by Ari Daniel of PRI's "Living on Earth." Below is an excerpt from the interview transcript
ARI DANIEL: Once in a while, if you’re lucky, you catch a glimpse of something that gives away a secret of the universe. It’s like a window – up into the heavens and deep into ourselves. This is a story about someone who poked his head through just this kind of window, and we find him in Atlanta. It’s a perfect day here – Jay Goodwin walks over to a bench to sit down. And he can’t help but be reminded about a day just like this one, 5 years ago, in western Michigan where he used to live. JAY GOODWIN: I was outside – I think I was going for a walk, just to kind of clear my head a little bit. I turned a corner, and I saw this flock of birds and they took off into the sky and they started to form a shape – sort of an amorphous shape. And it was one that was dynamic, and it was changing – but it had a boundary to it, like looking at a blob of oil in water. DANIEL: It stopped Goodwin in his tracks. Several hundred birds pulsing and dipping and soaring to an invisible beat in the sky. GOODWIN: It wasn’t clear what they were responding to – there weren’t any predator birds in the sky. And you never got the sense that there was anything that was directing it from within. There was no leader bird that they were all following. But just watching it was, well, it was beautiful. DANIEL: Goodwin realized he had no way of predicting the flock’s behavior by simply taking lots of individual birds flapping their wings, and adding them up. Rather, it was something that emerged once all these birds threw themselves together. And it’s this notion of emergence – how really complex patterns and properties can arise from combining somewhat simple units – that now defines how Goodwin thinks about his real work. Chemistry.  Goodwin heads into his lab at Emory University. He’s a chemist here. And since seeing that flock, he’s come to appreciate how molecules are a lot like birds. That is – you get to know how the individuals behave and parade on their own, but then, you put them together. And often, something new and astonishing emerges. You can read the whole transcript, and listen to the podcast, on the "Living on Earth" web site. Source: eScienceCommons

Global warming – an impeding catastrophe or a new stage of evolution?


Scientists have discovered that in the last 30 years, there has been an increase in the number and size of different plant species in the Arctic tundra. Besides, a bigger area is now covered with plants. The conclusion made by the scientists is that the summers in the Arctic are becoming warmer. Moreover, the process is interdependent – the warming of the climate encourages the growth of plants, which, in turn, encourages changes in a number of natural processes, which cause the Earth’s climate to become warmer. This research was conducted by an international group of scientists, headed by Sarah Elmendorf from the University of British Columbia, based in Vancouver, Canada. The scientists studied the data supplied by 50 research stations, situated in various areas of the Arctic. In all these areas, the picture was virtually the same – dwarf shrub and the grass become taller and spread over increasingly greater areas in Alaska, on Spitsbergen, in Iceland, Greenland, in Canada’s arctic zone and in Scandinavia. The increased plants growth is caused, of course, by global warming. The ice which stayed frozen for many years, if not centuries, is now melting, and, after a while, plants will appear in its place. Scientists even believe that leaf-losing plants, which are more heat-loving that the ‘traditional’ dwarf trees growing in the tundra, could soon oust the latter. It would be wrong to suggest that the climate changes which are taking place in the Arctic tundra have no effect on other regions. Andrey Shmakin from the Institute of Geography says: “If the ice melts – and that is what we are witnessing now – bare land starts to absorb a greater amount of heat. This is the main process that causes the global warming.” “Using the example of what is happening in the tundra, one can see that the balance of heat exchange between the atmosphere, the soil and the plants is now changing,” Vladimir Onipchenko, who chairs the department of plant ecology at the Moscow Lomonosov University, says. “And this is affecting the whole planet. Our observations in the Arctic help us understand more about the mechanism of the greenhouse effect, which worsens as a result of melting Arctic sea ice.” “The melting of ice speeds up the processes of organic decomposition in the soil, and greater amounts of carbon dioxide is emitted into the atmosphere,” Mr. Onipchenko says. “This causes even greater warming.” “If the pants of the Arctic tundra continue to grow taller and spread over a larger area, the tundra will start turning into a forest-tundra, where the climate is usually milder,” climate expert Andrey Shmakin says. “However, it’s a very slow process. The melting of sea ice could take many centuries, if not many thousands of years. Besides, it would be wrong to say that the ice is currently melting throughout the Arctic.” A lot of scientists agree that it is probably too early to make global conclusions – any moment, the planet’s climate could bring any surprise. After all, for thousands of years, the Earth has experienced warming and cooling many times – but life on Earth has survived.“Nothing catastrophic is happening,” Andrey Shmakin assures us. “The Earth is just entering a new period of evolution. Certain species of plants and animals might die off, others might come to change them – this is an eternal process.” Source: Voice of Russia

West Antarctic ice melts twice as fast as believed – scientist


.Subscribe
A research has been published this week saying that temperatures in the western part of Antarctica are rising almost twice as fast as previously believed. The discovery adds to growing concerns about the effects of climate changes.
The average annual temperature in the region has risen by 2.4C since the 1950s, which is three times higher than the average around the globe, David Bromwich, Professor of Geography at Ohio State University, who led the research, claims. The scientists claim that previously estimates, which are half of those they revealed, were based on faulty data, as one third of temperature observations had been missing for the past 60 years due to regular power outages and limited resources. There is a link between rising temperature and rising sea levels, the scientists remind. Even a minor temperature rise results in that huge blocks of ice slide into the ocean raising sea levels. The region contains enough ice to raise sea levels by at least 3.3m (10.8ft) if it all melted, a process that would likely take centuries. But, according to these findings, it is now the second largest contributor to global rises with 0.3mm per year to Greenland’s 0.7mm. Source: Voice of Russia

UFO mysteries

.Subscribe 
Files released from the National Archives at Kew today reveal that the Ministry of Defence in the UK took the threat of Unidentified Flying Objects very seriously. Under prime minister Tony Blair money and resources were devoted to checking whether any UFO was a reliable sighting. Dr David Clarke is a senior lecturer at Sheffield Hallam University and one of those involved in analysing the records. The Voice of Russia’s Tim Ecott asked Dr Clarke what lay behind the government's interest. Quite few were reports by credible witnesses, you know, pilots, aircrew, police officers that simply defy explanation on what they concluded might relate to very rare atmospheric phenomena – plasmas. And they were interested in this from the military point of view. Because they thought that they could harness these plasmas and use them. They could be useful on the battlefield.What is plasma? You know, like a lightning ball that aluminates sort of phenomena that appear and disappear. Now obviously there’s another serious aspect to this, because the Ministry of Defense were interested – I believe – in investigating some of these sightings because of the awareness that they could have been foreign aircraft, particularly from nations considered not so very friendly to Britain. That’s right, yes, and it’s a very detailed briefing in the files from 1995 by the intelligence officers saying that if these sighting are genuine – there’re serious national security implications. If foreign countries, presumably referring to Russia, China and US were able to set up flying without us knowing – then it’s something that is needed to be investigated. They didn’t rule out the possibility that there could be extra-terrestrials. If some of them are of extra-terrestrial origin then the reason they may be visiting include military reconnaissance, scientific exploration or even tourism. I wonder if this year’s wet summer reduces the number of aliens looking to come to Britain on holiday. I think you’ll probably find that likely. I mean most of the sightings that have been reported in recent years – if you look at them – orange lines, formations in the sky. The obvious explanation for those is release of these Chinese lanterns. For the public it’s quite amusing and interesting to hear some of the descriptions. I see amongst record are faceless humanoids in Wales, man in black in Lincoln chair, as well as these orbs in the sky. The one you mentioned from Wales – this was in the 1970s. Some of your listeners remember the Nude Triangle was popular around that time. And there were particularly lurid tabloid headlines, saying ‘We don’t need the Nude Triangle. We have a Welsh Triangle’. In this particular part of West Wales was a series of sightings there. There were sightings in the sky, people said that it seemed 7-foot-tall alien creatures in silver spacesuits prowling around at night. The MoD was inundated with account of these things. And we’re certainly to look into this. A man discovered that in a local shop window that being a fire-fighting suit on display that was used on a near-by oil refineries and this suit disappeared mysteriously for a few days during the period when people had reported these bizarre encounters. Putting two and two together he concluded that a practical joker had been at work. Something that always intrigues me: in the USA there is quite a wealth of anecdotes from people who claim to have been kidnapped by aliens for various purposes. They don’t seem to bother so much. No, really no. But there’s one counter of alien abduction from these files. From 8/17 Scotland, there were two people returning home late one night in 1994. And they saw the subject appear above their car and drop a curtain of light across the road. And then they lost a period of time, which are all classic symptoms of alien abduction. Where do you stand on this obviously from academic point of view? Do you have a personal view that you care to share on UFOs and aliens? My interest in this is from the point of view of being a folklorist, you know, when you go back in time, people believed in angels and fairies and goblins. And my view on this is that these believes are modern equivalent, like space-age folklore. You know, people have always got to have something to believe in, particularly in times of tension and war. People like to think that there is other intelligence in the universe, more advanced than us, which come along and sort our problems out.  Source: Voice of Russia

What trends will take upper hand in space exploration?

.Subscribe
Space exploration in the future is linked to the creation of habitable bases on the moon. This opinion was expressed by head of Russia’s leading research institute of the country’s space agency Gennady Raikunov. According to him, the potential of the International Space station has almost exhausted itself, and it’s high time to look “further and higher”.
Boris Pavlishev, At present, large amounts of equipment are installed on board the ISS with great difficulty. The station is experiencing a power shortage. After 2020, its use has to be gradually reduced, and we must shift to the moon that has unlimited space. Radars and large equipment can be installed on the moon. Lunar bases would help people acquire experience to live on another planet. After melting ice, water can be reduced to oxygen and hydrogen that can be used as fuel for rocket engines, the scientist says. The U.S. planned to return to the moon but during the Obama Administration, these plans were abandoned. The American President has called a visit to an asteroid by the middle of 2020s as a priority. Concerning the choice of asteroid NASA official John Charles has this to say in an interview with the Voice of Russia. However, a flight to an asteroid is as dangerous as a flight to Mars. The reason here is that a cosmonaut will get a similar dose of harmful radiation when he stays in interplanetary space for several months, says director of the Space Research Institute, Lev Zeleyony. He insists that the moon is much more favourble. “A bunker can be built at a depth of 1.5-2.0 meters below the moon’s surface. Cosmonauts can live there without coming out to the surface. There are materials to protect them. It’s unclear how to protect oneself from radiation on an asteroid. It takes only 2 to 3 days to fly to the moon. There is lot of interesting physics there, and there may be organic matter brought in by comets. In short, people have a lot of things to do there,” Lev Zeleyony said. There is no need for cosmonauts to consistently stay in the research base subjecting themselves to unnecessary radiation. They can watch over scientific equipment working in shifts. The scientist believes that asteroids should be studied using automatic probes without risking human lives. Russians and Americans have made their choices with regard to where they should fly after the Earth’s orbit. Each side will search for new arguments to convince the skeptics. However, all disputes will end some day because there is only one sacred goal for the space powers. It is the flight to Mars in the middle of the century. One country would hardly be able to carry out the mission on its own, so most likely, the expedition will be multinational. Source: Voice of Russia

Global warming: hype or fact

BjÞrn Lomborg, a guru of climate change research, shares his take on global warming and what stands behind it
.Subscribe
By: Yekaterina Kudashkina, Please, tell me, do you think that there really is a connection between the growing number of natural disasters and the global warming process as such? Well, first of all global warming is real, it is men-made and it is an important problem. But the way it is often being portrayed as the cause of the vast majority of extreme weather incidents is simply unfounded. If we look at a lot of the catastrophes that we’ve seen over the last years and that have been very well published, they are by far mostly driven by social factors. If you look for instance at hurricanes – the reason why we have ever more damage from hurricanes is because many more people live on coastlines and typically with more and more wealth. If you actually correct that, and we have the best data for the US, you’ll see no change in incidents whatsoever. And there is purely radical reason to believe that by the end of the century we will probably see slightly stronger hurricanes, probably also slightly fewer, but this is really not what we are seeing right now. What we are seeing right is that we have increasing social vulnerability because of more people and more stuff. Sir, when I was looking at various figures, I’ve noticed that some scientists are saying that for the past 14 or 15 years the temperatures have not gone up, while others are saying that this is perhaps just a brief period. Well, both of these effective people are right. The temperatures haven’t risen for the last 16 years. But if you look at the overall picture it is likely that we will continue to see temperatures increase because of global warming. But of course the important part of this is not as it is often portrayed in the sort of skeptic argument – oh, maybe there is nothing about global warming. But it does tell us is that it is unlikely that the worst outcomes of global warming that have been forecasted are going to happen because clearly there are natural variations that are counteracting global warming and probably indicating that global warming overall is less strong, not more strong. Sir, I’ve got another question. If we look at the whole history of climate conference, climate change discussions and whatever – it looks like the general public is a little bit distrustful of all those things which are being published about global warming, about cutting down CO2 emissions. My hunch is that as soon as money steps in people tend to become suspicious, or perhaps there could be some other reason. Why wouldn’t people buy what we are saying? Why wouldn’t they see it as a real threat? I think there are a number of different answers to that question. One is that it is very clear that a lot of people become suspicious about the global warming hype because we always, when there is a UN meeting, hear about how things are terrible and how we really need to amend our ways. That perhaps is not entirely how fine it works, that is more how press releases and media campaigns work. And we also have debates which indicate that people are getting more skeptical about this argument. But I think it is important to say that just because there is bad media hype around global warming doesn’t mean we shouldn’t fix it, it doesn’t mean it is not a problem. It is a problem, we should fix it, but we should probably start looking for different answers. As you rightly mentioned – we’ve been meeting for twenty years now trying to cut carbon emissions and the net effect has been almost zero. If you look at the entire twenty years the emissions have risen about 50%. And we have a good reason to believe that if we had no amount of agreement, nothing whatsoever, the emission would probably have risen about half a percentage point more. So, fundamentally, what we’ve managed over twenty years of talks and huge amounts of time and lots of people involved is that instead of rising 50,5% it only risen 50%. But obviously, that indicates that we are not getting at the root problem. That’s why I think we need to have a different kind of conversation and start talking about what would actually work. I think that in one of your recent articles you’ve described a very interesting experience of the US, which by the way has been much criticized for not signing up to the Kyoto Protocol and for being in fact the largest polluter. It is an interesting story which is about the fracking of natural gas. The US is emitting a lot more CO2 per person in the world and hence it’s been criticized a lot because it used to be the biggest emitter. But what the story of the US also shows is that how technology can make a huge difference. The US has basically managed to frack natural gas, which means you can get a lot more natural gas, and it meant that the price of natural gas on the US market has dropped precipitously, probably somewhat between 60-90% over the last five years. So, it became much cheaper. That means that a lot of producers of electricity have switched from coal to gas because gas is now cheaper. That matters because gas emits about 45% less CO2 per energy unit produced than coal does. So, the US has actually dramatically dropped its carbon emissions over the last couple of years. We are estimating that they have probably dropped the annual emission because of the shale gas about 400-500 megatons. To put that in context, the entire effect of cutting carbon emissions in the Kyoto Protocol and everything the EU has done is about 250 megatons. So, the US has managed to cut twice as much from what rest of the world plus twenty years with all the conventions and the Kyoto Protocol has managed to do. And instead of paying for it, the EU is paying between 20 to 30 billion euros a year, the Americans are making money out of it. They are actually saving about a hundred billion dollars a year. This is the way forward – to get carbon cuts while you actually make your nation richer with obviously a much more easier way to sell carbon cuts, than trying to sell almost meaningless carbon cuts at very high cost. And finally, Mr. Lomborg, I though you also used to come up with your own solutions to the problem. Could you brief our listeners a little bit on that? Well, if we are talking about climate catastrophes, if we care about the people, and especially developing country persons, who are going to be hit with hurricanes, with large downpours and all the other problems that come from a variable weather – we should not predominantly focus on the climate solution. Because even if we did the climate solution – it would only help them very little a hundred years from now. We should actually focus on cheap and effective adaptation right now. If you look at hurricane Sandy, which obviously got a lot of attention because it hit right before the US presidential elections, if you focus on what you should have done to avoid the hurricane Sandy and what should you do to avoid future hurricanes Sandy, it is very clear – it is not about cutting carbon emissions which would do virtually nothing, it is about making simple adaptations, it is about making coverings for subway stations so that your subways don’t get flooded. It is about making sure that people don’t have easy access to subsidize the insurance and so they build irresponsibly on the first bare island. It is about very simple, very cheap proposals that will actually have a huge impact. So, again, we are back to the situation, when we talked about global warming, - do we want to do stuff that just makes us feel good – that is make proposals to cut carbon emissions that virtually makes no difference in a hundred years – or, do we want to do stuff that actually does good. Let’s focus on the policies that actually help poor people around the world with adaptation and then make sure we use technology, like fracking, to cut carbon emissions. Source: Voice of Russia

What is the Universe?

What is the Universe?
Dark energy and quasars - they're mysterious forces behind the creation of the universe that few of us understand. But scientists now claim they have discovered that the speed at which the universe expands varies with time - and it's now accelerating rapidly. Dr. Mat Pieri from Portsmouth University is the co-author of the study - we asked him how it was possible to measure the speed of the universe's growth.
.Subscribe
 I think it useful to start with what’s happening with the universe in the present days. The universe appears to be accelerating in its expansion in that’s mysterious substance we “call dark” energy, which is really just a name of something we don’t understand, honestly. So if we go back to the first step of the history of the universe, that expansion was actually decelerating and that deceleration was caused by the gravitational pull of the objects in the universe of that time. When you say the universe is expanding and doing it more quickly, presumably, these’re forces and magnitudes of size that’s very difficult for the human brain to understand. Yeah. It’s an odd scale in general. It’s very difficult to wrap your head around the kind of physical scales that we’re probing. We’re looking at the universe 11 billion years ago. The universe was a different place then, it’s very difficult to picture what it was like and what kinds of scales are being discussed. We’re really looking at structures in the universe on truly mindboggling scales. Typically, we think that the scale of the galaxy is pretty mindboggling. But then you have to a whole of the scale where a galaxy is like a point and you just have enormous distribution of these points. It’s really mindboggling scales. And you’re talking about a period – 11 billion years ago, a scale that really doesn’t mean much for most people, because it’s so huge. In the essence, I believe, your research measures the distribution of gas in different areas of what we call the universe. That’s right. And I think that’s quite a unique technique. We’re looking at background objects, it’s not really important what they are in the purposes of this brief discussion, but these are very bright distance sources of light in the early universe. And what we do is effectively we see what happens to light when it leaves one of them and its voyage all the way to Earth. So, in principle, at least that whole voyage could be displayed out on the properties of that light. And do we know what these gases are? Yeah. I’d say we do. There’ve been various studies in the past about this gas which we know as “intergalactic medium”. We know quite a lot about it. And what we haven’t really done is mapped out on a kind of scale that we’re doing today. This intergalactic medium is mostly pretty remote stuff, but there’s really no part of the universe that is really empty of matter. There’s always something. And that’s what we’re looking at. Does it help us understand how it all came into being, in the first place? That’s a big question. I think it’s really baby-steps towards that question. What we’d like to know first is what this strange matter the universe is made of is. And then maybe after we understand what dark energy is, maybe we can say a little bit more about the way the universe came to being. I think it’s slightly a different question in the sense that there’s genuine debate whether it’s even possible to know what started the universe, what caused the big bang. So I think we have to satisfy ourselves with the question of understanding what the universe is before how it came to be. Source: Voice of Russia

Russian scientists one step from creating AI?

ЌПзг гПлПва

By Yelena Kovachich, Russian scientists have created a computer analogue of a human mind, the possibilities of which lag behind that of a human brain only by 0.8%.At an international contest of similar computer programs, which recently finished in London, this Russian program won the first place. All the contesting programs had to undergo the so-called Turing test. In 1950, UK mathematician Alan Turing, one of the first developers of computer technologies, suggested a test (although, at that time, it had little scientific significance and was rather a game). The rules are simple – the examiner communicates with an anonymous partner who can be either a human or a computer program. The examiner neither sees nor hears his partner – he only receives printed answers to his questions from his hypothetical interlocutor. The examiner has to guess whether he is communicating with a real human or with a computer program. As a rule, after some time, the examiner guesses it right, because no computer program that can fully imitate human thinking has been created yet – if it may ever be created at all.In an interview with the Voice of Russia, Mikhail Gorbunov-Posadov from the Institute of Applied Mathematics said: Source: Voice of Russia.

US scientists: biohackers could harm human brain

US scientists: biohackers could harm human brain
.
By Sergei Mizerkin, US scientists claim that ‘hacking’ a human brain and then controlling a person is a matter of time. According to the scientists, synthetic biology, which is a new branch of gene engineering, may help create special microorganisms capable of intruding the brain – a process that can be likened to malware hacking a computer. US scientists claim that ‘hacking’ a human brain and then controlling a person is a matter of time. According to the scientists, synthetic biology, which is a new branch of gene engineering, may help create special microorganisms capable of intruding the brain – a process that can be likened to malware hacking a computer. With US pundits already drawing parallels between cyber and bio crime, Russian scientists are warning against jumping to conclusions. Alexander Kaplan, of Moscow State University’s biology department, says that drawing parallels between a computer and a human brain is irrelevant if only because the brain is much more sophisticated than any computer system. In this regard, the US scientists’ allegations are yet to be confirmed by practical experiments, Kaplan says, adding that implanting bio viruses in a human brain will certainly be a tricky task. "The mystery surrounding the human brain is yet to be unravelled, Kaplan says. It is still unclear whether we will ever be able to obtain information from the brain by implanting bio viruses there. There are at least 100 billion neurons inside the brain and duly implanting a bio virus there will be a hard nut to crack, Kaplan says. I think, he adds, that this task will be very unlikely to be implemented in the foreseeable future. I would even say that hacking a human brain with the help of a bio virus is an unreal task." Generally speaking, it is extremely hard to create an artificial gene, Kaplan says. "After the emergence of living cells on Earth, it took nature about one billion years to create worms which can be called the first intelligent creatures – an evolution that we should bear in mind when speaking of a possibility of hacking a human brain." Hypothetically, this task can be fulfilled, believes Vladimir Korovin, head of the Agency for High Information Technologies in Moscow.
