The question of whether to send extraterrestrial civilizations rays of friendship and mutually beneficial cooperation (or the opposite), can be expressed in the language of numbers, I'm sure a mathematician from Austria.Sending messages in open space - "active SETI» - business, strictly speaking, risky. We do not know whether the friendly people who get the message, as well as the extent to which it is they do not have enough Lebensraum. That's why some stakeholders, including milneonera Stephen Hawking, oppose such a risky game with many variables. Others, however, ask a reasonable Read more [...]
Monkey, which goes out to hunt at night, and its bite is poisonous enough to kill a person can - was discovered by scientists in Borneo. Beware!

12/13/2012 After the study conducted by French scientists found that rats fed genetically modified maize Monsanto appeared malignant, Russian scientists wanted to have its own public experiment. It is expected that the unique reality show with rats help prove or disprove the harmful effects of GMOs.Russian scientists who oppose the use of genetically modified organisms in food, hoping that the experiment of one year will show whether the genetically modified organisms has such dangerous consequences, which were discovered by French explorers on 19 September.Scientists from the University Read more [...]
Women are always complaining that they have your arms and legs. Doctors are convinced that it is a feature of the body, caused by hormonal level. Heat receptors are an inch from the surface of the skin, says Professor Michael Tipton of the University of Portsmouth.Through capillary blood skin usually maintain a comfortable temperature. But in women, depending on the level of estrogen the body temperature fluctuates, as it controls the peripheral vessels. The more of the hormone in the blood, the higher the sensitivity of blood vessels to the temperature. This writes MedDaily. When cold receptors Read more [...]
An international team of scientists led by Professor of Moscow State University to study in detail the composition of normal frog skin secretions, and came to the conclusion that the folk tradition to throw a frog in milk has a scientific basis.Having read Russian folk tales about how thrown in a can of milk frog protects the valuable product of souring, the scientists were able to identify a large group of antibacterial substances excreted through the skin, a simple grass frog. The report on the study published in the Journal of Proteome Research.The leader of the research team, Mr. Lebedev Read more [...]
12/13/2012 Scientists have developed a new view of biological time - it turned out that for many problems while conveniently presented not as the axis, and as a two-dimensional surface in three dimensions. The new approach now appears in the form of a two-dimensional surface, given as follows. There is a central axis, which is the usual time. Along this axis, "rides" perpendicular vector rotating with a large period of 24 hours, to which is added the periods of processes such as breathing and heartbeat. As a result of the end of the vector describes a curve in space, which can be viewed Read more [...]
12/12/2012 According to the new theory, the researchers suggest that the "black holes" have properties that are similar to the dynamics of how solids and liquids. Nils Obersee, a professor of theoretical particle physics and cosmology at the Niels Bohr Institute at the University of Copenhagen, says that "black holes" can be regarded as a particle. Particles, in principle, do not have the size and can be converted to any object.According to string theory, the various battles that act as "black holes" are called black brane. Black branes are heat, that is, they have Read more [...]
The rhythm of climate change that occurred in the last million years of Earth's history, is determined orbital cycle: Depending on the amount of sunlight that glaciers are growing, then retreating. Responds to change the entire planet - from atmospheric and ocean circulation to ecosystems and even erosion and sediment transport.New research suggests that it affects the volcanism. Scientists in the past have noticed similar correlations for limited periods of time and at a regional level, and the new work provides a broader picture.fridgeirsson).
