Channels in the brain need ongoing training. Intellectual classes help maintain normal functioning of the brain in old age, reports Science Daily.
This is the conclusion drawn by researchers from Rush University in Chicago. "Reading the newspapers, writing letters, going to the theater or a library, or mind games, such as chess - simple exercise that can contribute to the health of our brain," - said the leader of the research team Dr. Konstantinos Afranakis.
Scientists examined with MRI 152 volunteers, whose average age was 81 years old. The relationship between the structure of the Read more [...]
German biologists have studied the unusual mechanism by which the carnivorous sundew Drosera glanduligera Australian catches his victims. This species feeds mainly flightless arthropods trapped in the center of bowl-shaped leaves with sticky hairs. But unlike other sundews this is not waiting for some interesting bugs themselves will enter the danger zoneTrap frame of 12 to 18 thin tentacles, which, like a catapult throw careless insects in the center.
Of course, such an original way of catching dinner was known for a long time. But now scientists at the University of Freiburg (Universitat Read more [...]
In order for the information was passed to the brain, nervous tissue cells - neurons - to form bonds, so-called synapses. But, as it turned out, in the wild they do not need everything. Scientists at Yale (Yale University) discovered that nerve receptors in the antennae of flies can communicate with each other without any synaptic connection.
The possibility of the existence of the so-called efapticheskih ties predicted Rospar Jean-Pierre (Jean-Pierre Rospars), entomologist from the French National Centre for Agricultural Research. It happened in 2004. Now, researchers working under the direction Read more [...]
French scientists have found the answer to the question of what attracts a woman a man, when he sees it for the first time. Scientists have already been proven that people choose one another at the genetic level. A new study shows the principle on which men choose their partner. Looking closely to the woman, the man primarily guided by her appearance. The females believe that a man can attract a slender figure, breast size and leg length. But in reality it is not. The man initially drew attention to the girl's face and chooses his girlfriend on her similarity. But not with the mother, Read more [...]
The benefits of hormone pills and patches are now many doctors say. These drugs reduce the risk of inflammatory diseases, help easier to carry age-related changes, improve the condition of hair and even promote weight loss ... But the most important - they allow you to plan a pregnancy. When doctors recommend hormone pills, they really believe in it. But there is another point of view. Hormonal contraceptives mutilating women. They can even kill. And such cases thousands, perhaps hundreds of thousands, because there is no accurate statistics. This was not reported in the media, because Read more [...]

"Surviving on high altitude challenge our concept of limits of the biosphere," - so says David Smith of the project "Micro-organisms in the stratosphere" Kennedy Space Center. The scientist and his team are planning to establish the boundary of the biosphere by sampling Observatory "Batchelor" in central Oregon.
The first found alive oragnizmami in the stratosphere were bacteria. The bacterial form of life is possible in such harsh conditions of existence through the formation of a protective shell - spores. Only thanks to her bacteria can live at? 56? C in the Read more [...]
A group of scientists from the U.S. and China, with the help of computer simulations find an answer to an old question, what does is the core of the Earth.As shown by simulations, the Earth's core contains mostly carbon in an amount of 0.1-0.8%, as the largest reservoir of carbon on the planet. These are the information provided by the U.S. researchers from the University of California at Davis, and specialists from the Chinese Academy of Sciences. The study appears in the current issue of the Proceedings of the National Academy of Sciences."We were known density of the nucleus, and Read more [...]
Clearly, all our thoughts and feelings are accompanied by changes in neuronal activity, but this kind of change? As occurs, for example, switching between two possible answers to the question "to drink or not to drink?" Now we have the data in hand, allowing to present some of the neurons that accompanies the decision: researchers from the Massachusetts Institute of Technology (USA) was able to see, thabout
happens in the brain is a change in behavior (although the details and all sorts of special cases of this mechanism is still working and working.)bionerd.) "Width =" 600 Read more [...]
In the Netherlands, learn to create open microprism that can be used as individual "prison" of the studied living cells.Most cell research is done "on the plane", although this is far from the natural behavior of the cells, which require sufficient space for themselves in all three dimensions. This opportunity is open to the pyramids, created by the Institute of Nanotechnology at the University of Twente (Netherlands).The report on the study published in the journal Small.Chondrocyte cell, caught in the open microprism began to talk with the neighbors. (Hereinafter, Read more [...]
Components of hairspray based on lower chlorofluorocarbons, once successfully banned on Earth, may have the widest circulation in the a number of the planets of the universe - and give it the presence of intelligent life.How would humanity be desirable for the stars, if it does not develop a way to make huge amounts of energy with almost no effort, his nearest future will be significant space terraforming Mars. Recall that in order to get to it, enough to accelerate to 1/10 000 of the light speed and then slow down - and it is unimaginably better than traveling the speed of light. After all, Read more [...]
The universal quantum state tomography method developed at the Institute of Physics and Technology, Russian Academy of Sciences, in close cooperation with the Moscow State University. MV University told head of the laboratory of physics of quantum computers Physics and Technology Institute of Sciences Prof. Yuri Bogdanov. This method allows to deal with a major obstacle to the development of quantum computers - the phenomenon of decoherence.According to the famous American physicist John Archibald Wheeler (John Archibald Wheeler, 1911 - 2008), about one-third of the U.S. GDP is directly based Read more [...]
Time moves inexorably forward. It should scroll film's back - and you immediately suspected something was wrong. But from the point of view of a single, isolated particle over time looks the same in any direction. That, at least, it seems at first glance. For example, a film of the scattering of two particles will look reasonable, even if the scroll backwards - a concept known as the symmetry of time reversal. Now the experiment authoritative scientific collaboration (it full-time or part-time participation in the simultaneous) BaBar, working with the accelerator SLAC, found new, though Read more [...]
One located in the Atlantic volcanic eruption in the case can cause huge ocean wave that could drown the Caribbean and large parts of the east coast of the U.S. - the scientists say.
Dr Simon Day, of the research center at University College London warns that one of the slopes of the volcano Cumbre Vieyha, located on the island of La Palma, Canary Islands is unstable and could collapse into the ocean. Swiss researchers have modeled the landslide, they say that the water could collapse rock weighing half a trillion tons, will result in a wave height of 650 meters, able to quickly cross the Atlantic.

Researchers from several U.S. universities have come to the conclusion that one of the genes contributing to the emergence of cancer, at the same time involved in the prevention of atherosclerosis of the coronary arteries.This gene called Akt1. In recent years, it was shown that the enzyme of the same name, the synthesis of which he starts, protects cells with structural abnormalities of genetically programmed cell death - apoptosis. As a result, they continue to multiply, and in the end often undergo malignant transformation.
Animal studies have shown that increased activity of the gene Read more [...]

The scientists studied 15 healthy fetuses in video format 4D, to find out, can you still unborn baby yawn or just opens his mouth as some researchers. The study was conducted with the participation of women with gestation of 24 to 36 weeks. Eight of them were waiting for the girl, and seven Read more [...]
Human stomach may think. The number of neutrons in the gastrointestinal tract of a lot more than in the brains of some animals. This suggests that in the belly we have a second brain.
Secondly, the body is covered with hair on having the same structure as in most other primates.
Third, as part of the human DNA have viruses. By themselves, they do not breed, but they can be copied by introducing its DNA into the host cell. If the DNA of the virus enters the cell of sperm or ovum, is obtained from the seed virus DNA in each of their cells.
Fourthly, the man partially blind. The structure of Read more [...]
