According to scientists one big solar storm can cost about U.S. $ 2 trillion. for damages vital communication systems and power grids.The new radio telescope, located in the remote outback of Western Australia can get one of the best views of the sun and should be able Read more [...]
Each year, scientists ascertain extinction of hundreds of species of plants, animals, fish, insects and birds. Against this background, it becomes a sensation of discovery of new species. On one of these discoveries recently announced by Australian scientists. They have discovered a new species of lizard, not in remote areas of the island, and on the outskirts of a major city of Perth in Western Australia. Lizard discovered by accident in the study of biodiversity southwest of the country. "The discovery of new species is a significant event in the world of science. Detection of a new Read more [...]
Light two obvious inherent physical properties - color and clarity. Indeed, the light may be white, yellow, red, green, purple, or have other colors. Transparency by the fact that through the light we see material objects. Transparency has the light of any color. And the light - it's not gas, not solid and liquid matter. I am deliberately not talking about the wave and the nature of light, as we face another problem.
Everyone knows that in the dark space. But we can see the stars. It speaks about the transparency of the cosmos. Aristotle believed that the fire was visible in the dark, Read more [...]
Emotions - it's specific sensations experienced at this time, expressed as a positive or negative attitude of the subject to some important object for it. The physiological basis of the origin and development of the emotions is a need to implement an individual program, in which a person has certain requirements are necessary to ensure their livelihoods, but also determines the choice of direction for individual self-fulfillment. The implementation of these requirements is accompanied by a deep sense of emotional satisfaction, ie evokes positive emotions. Inability to fulfill their needs Read more [...]
Attention- Reflects the direction and focus of the human mind to a particular object, which ensures a particularly clear expression. The main functions of attention:· Providing selection coming into the body of information in accordance with its actual needs.· Employing selective concentration and prolonged mental activity on a single object or activity· Activation Read more [...]
God - not Chernomyrdin and Chubais. Therefore, to say that God has collected a huge amount of gas, and gave him a demonstration in the burning sun on a great joy to humanity, such as serious. A write to the Great Soviet Encyclopedia of continuous decrease of the mass of the sun (of course, if something is burning, it burns something) even more fun. Campfire on a cosmic scale. Only from firewood? Nearby forest, then to be seen. And the gas fields Gazprom did not report ...
2. Obviously, the sun does not burn, is growing, increasing the mass, and, finally, it has a solid surface. All of these Read more [...]
Back in 1968 American science fiction writer Philip K. Dick wondered, Do Androids dream of Electric, and wrote about this whole affair. Exactly 45 years later, the same question could attend Japanese astronaut Koichi Wakata, however, it is unlikely that he will have time to write a novel.In the summer of 2013, engineers at Tokyo University, in collaboration with a Japanese advertising companies want to send to the International Space Station (ISS) with Wakata robot android KIBO («Hope"). The robot will help the astronaut to communicate with Earth.Scientists plan to make two copies Read more [...]
According to scientists, the relationship with cancer is already installed for almost every product. In fact, almost all the studies on this subject have no statistical significance and did not receive further confirmation.Tabloids and women's magazines are full of horror stories about carcinogenic products. The main role could be anything from toast to fat-free salad dressing. But U.S. scientists warn that many studies have established a link between cancer and the most common food, does not really hold water.Jonathan Schoenfeld of the Harvard School of Public Health and John Ioannidis Read more [...]
According to one hypothesis, the man got a big brain with the permission of immune cells, which in return had to be "blind eye" to some infectious diseases.Hundreds of thousands of years ago, certain genetic adaptations have allowed people to come out of Africa and spread throughout the land. Researchers from Cambridge (UK) suggest that modern humans can detect traces of the genetic changes that occur in an unusually diverse set of natural killer receptors.Natural killer (NK) are a special kind of immune cells with two very different functions. The first - to find and kill all the Read more [...]
Previously, scientists have found that women, on average, say about 20,000 words a day, while men - less than 7,000.Neuroscientists and psychologists at the University of Maryland found that the verbosity of women due to the fact that their brains more protein Foxp2.Scientists point out that if people just women have more of this protein, the rats developed the opposite situation. Experimenting with rats, the researchers found that the four-male "yell" (in the ultrasonic range) are twice as likely females when they are separated from their mothers. Altering the protein content Read more [...]
Scientists from the Australian National University found near Melbourne meteor crater with a radius of 200 km, said Wednesday the Australian newspaper "Herald Sun".
As noted researcher Andrew Glikson, "is the third of the large craters ever found on Earth."
In his words, "the crater was formed by the fall of an asteroid the size of at least 10 kilometers." The scientist noted that "asteroid collision with Earth this magnitude was not only regional but global implications." E.Glikson suggests that in the fall of this celestial body is about 300 million years Read more [...]
Assumptions about the number of alien civilizations with whom we can establish radio for decades based on the Drake equation, and the axiom of the impossibility of intergalactic radio. May both need to be revised.Drake equation, obtained in the same year, when mankind first came out in the cosmos, in its classical form is more of a statement of our ignorance. Although the presence in the text of a formula reduces the number of read it twice, I venture to remind you:N = Ns ? fp ? ne ? fl ? fi ? fc ? fL,where N - the number of intelligent civilizations, ready to make contact, Ns - The number Read more [...]
Earth is in danger she faces global warming or an asteroid collision-killer. Caravans spacecraft with humans on board to go and find a spare planet. To save mankind, there is the main question: how to keep your line in zero gravity or in the same spare the planet? "I think that the selection is small. Fact these planets, which can absorb at least hypothetically, only two. This Venus and Mars" - said a senior researcher at the State Astronomical Institute of the PK Sternberg (SAI) Vladimir Surdin. But if the conditions on Mars are more or less suitable for life, on the surface Read more [...]
The number of people suffering from loneliness in the world is growing exponentially, say psychologists.According to experts, more than 30% of people in the world suffer from loneliness and emotional isolation.Psychologists point out that the development of new technologies, in particular, communication on Skype over the internet, only adds to this serious problem. Such pastime does not replace our joy full of live communication.In addition, people suffering from loneliness, not inclined to share the problem with others, though, and in dire need of support and sympathy of friends.Scientists also Read more [...]
Famous gulf already seems old. But it is believed that in reality it is much older.According to most geologists, the Grand Canyon came 5? 6 million years ago due to the fact that the Colorado River eroded the rock layer by layer. One of the proofs - huge piles of washed gravel on the western end of the canyon, which appeared just at this time.But the new study focuses on other breeds, naked throughout the canyon. When erosion takes the material on it, stone cold. Traces of the cool stores in several ways, including in the form of helium in apatite. "When apatite hot helium leaves the Read more [...]
Canadian and American linguists have developed a special computer algorithm that can reconstruct the ancient proto-language spoken by the ancestors of modern language groups and families, which will help to restore the history of civilization on Earth."We hope that our algorithm will make a revolution in historical linguistics, about the same as the statistical analysis and computational power of computers have transformed evolutionary biology. Though our system can not find all the nuances that can be seen by professional linguists, it will help them to use more languages the reconstruction Read more [...]
Drugs to help treat anxiety, was found in the water. As it turned out, these tools are changing the behavior of fish. They begin to stand out from the jamb and eat all the food available to them, says Counsel & Heal.This discovery is the University of Umea. Scientists investigated the effects of oxazepam - means changing moods. We measured the concentration of the drug in Firis river running through many densely populated regions. It was established that in the perch have at least 6 times more medicine than in water. Moreover, the fish behaved more risky, separated from the shoal. That Read more [...]
Lake Don Juan in Antarctica - the salty body of water on Earth, so it never freezes. Researchers have found a new hint that the origin of so much salt, and the results can clarify the question of liquid water on Mars."The idea was simple - tells James Dixon of Brown University (USA). - We decided to make 16 thousand photos of the lake for two months to find out which way the water flows. Take pictures, we compared them with other measurements made by ourselves, and the story told itself. " It was found that the water level is raised in accordance with daytime temperatures, that is, Read more [...]
In 1953, James Watson and Francis Crick determined the structure of DNA is a double helix. Scientists have determined this by using X-ray diffraction data obtained by Maurice Wilkins and Rosalind Franklin.
This method of analysis is based on the diffraction of X-rays on the three-dimensional crystal lattice, the nodes which in this case were located DNA.
The diffraction pattern is recorded on a photographic plate. In the case of DNA, the output image is a complex combination of points, the position of which is determined by the arrangement of atoms in a molecule. "Explanation" of such Read more [...]
Coastal areas of the Earth in the near future subject to flooding: sea level rises faster than you anticipated. These pessimistic forecasts were made at the UN conference on the fight against climate change, which takes place in Qatar.In the course of its scientists, meteorologists reported that the sea level rises to 60% faster than expected in the last 20 years, the water was coming to an average of 3.2 millimeters per year. This is the fastest growth in sea level over the past 2,100 years, according to the BBC Russian Service.Scientists at the Potsdam Institute for Climate Research said that Read more [...]
