"I'm redder than red", Bob Marley once sang, but he probably never imagined that chemists will be able to "see" the tone. This had a little tweak of color-sensitive pigment of the human eye to teach him to absorb the wave of far-red range.Color vision of almost all animals provide specialized chemicals - chromophores, which are comfortably ensconced within the protein molecules adsorb light in the visible range. It is believed that the structure of protein molecules "nests" to a large extent determines the absorption spectrum of sitting inside the chromophore Read more [...]
You can catch a liar, not only by his gestures and facial expressions. Spanish scientists from the University of Granada have shown that when a person intentionally introduces his companion astray, he heats the tip of the nose.Emilio Gomez Milan and Elvira Salazar Lopez Department of Experimental Physiology became the first to use in their research thermography (a method of obtaining images in the infrared, showing the distribution of temperature fields). Their discovery suggests that, depending on the internal state of its human body parts can be heated or, conversely, to cool.Thus, during sexual Read more [...]
Romany originated in northwestern India about 1.5 thousand years ago, and after six centuries migrated to the territory of Europe, the conclusion made by the European Genetics, analyzed the genome of the people. According to specialists, the most likely home Roma are the territory of the modern states of Gujarat, Rajasthan and Kashmir."From the point of view of genetics, all Roma combines two things - they come from the north-western India, and their ancestors intermarried with other peoples during migrations across Europe" - leads UPI.com words of the head group of scientists from the Read more [...]
Absorbing Nickel archaea could exacerbate Permian catastrophe active methane production. A nickel they took from the Siberian Traps. At the end of the Permian period (about 250 million years ago), for some hundreds of thousands of years on the planet disappeared and 90% of all species.
According to the fossil record, first life slowly withered due to the gradual acidification of the ocean and the reduction of oxygen in the air and water. Those who remained, killed volcanoes and meteorites. According to another theory, the atmosphere was methane deposits, usually hidden in the seabed, leading Read more [...]

Norwegian researchers from the clinic Sykehuset Innlandet found that visits to the church are beneficial not only to the spiritual, but also physical health.
According to the scientists, going to church reduces blood pressure in hypertensive patients. The more often a person is in the church, the lower the pressure.
Previously to such conclusion the American scientists, but then it announced just a coincidence because the church in the United States, regularly goes up to 40% of the population. Norwegian experts study more accurate, because in this country go to church no more Read more [...]
North Star (Polaris), amazing long and thorough. Someone seemed to be specially "hung" in the sky that the brightest flashlight to travelers from ancient times to focus on it. I "hung" so that the earth's axis put her right into it - its northern (polar) end.Now the North Star is interested specialists in space navigation and ... interstellar communications. Interested, as a representative of a mysterious galactic family - Cepheids. A such beacons in interstellar space. She - the closest to the solar system such a beacon. Recently, astronomers have refined the distance Read more [...]
The researchers argue that prolonged sitting - the great harm which many love causing their health every day. The more time a person sits, the more shortened his life.
As we know, prolonged sitting can lead to cancer, obesity, diabetes type 2, cardiovascular disease and even premature death.
One study of the American Cancer Society found that women who sit six hours a day are 37% more likely to die prematurely than those of the fair sex who spend a lot less time sitting.
In addition, sedentary lifestyle has significant metabolic consequences. It affects the blood sugar, triglycerides, cholesterol, Read more [...]

A group of scientists from the Chinese University of Science and Technology, led by Xiao-Hui Bao, quantum teleportation could provide information on the distance of 150 meters. For this purpose two groups of rubidium atoms. These groups, which are quantum objects, entangled with the photons of laser light. After tangling scientists alter the quantum state of one of the groups of atoms, and this change is immediately manifested itself in the second group of atoms.
Xiao-Hui Bao and his team are going to increase the time that a group of rubidium atoms can maintain the integrity of the quantum Read more [...]
Directed by Edgar Wright recently announced plans to make a film whose main character Ant-Man will be able to decrease the size of the insect. In the comics, based on the movie which will be delivered, and the ants also appear the size of a human. And can it be, really? Their views on this issue are divided scholars.
In short, the researchers can not give a definite answer to this question, although there are several hypotheses to explain why the ants and other insects have exactly that size. The first hypothesis, says psychologist John Harrison of the University of Arizona, Read more [...]

Gene mutations in humans increased so that geneticists think about new ways of reproduction. July 10 in Moscow Professor of American Institute of Psychiatric and Behavioral Genetics, Michael Reimers read a public lecture "Recent evolutionary changes in the human genome." The professor started the bat, recognizing that the scientific world is still no agreement on the evolution of man. Some researchers believe that at the moment of human evolution has slowed down (meaning the genetic changes), while others believe that the accelerated, and ten times.
The two "most recent" Read more [...]

Synthetic biology regenerates the body, completely synthesizing the genome. In fact, the scientists were able to do something that could not be of medieval alchemists. Ten years ago, the scientific community was excited - the scientists began decoding the human genome. From this discovery, many were expecting more practical results, but the path was tortuous. And today geneticists are still more questions than answers. One of the leading Russian scientists, Professor Lev Patrushev in an interview to "Profile" told that we can not only heal, but also to predict the disease, why you Read more [...]
The authors of drawings on a cave better versed in the anatomy of tetrapods than most modern artists, and made fewer errors in the figures walking mammoths and other mammals, RIA Novosti reported with reference to the article published in the journal PLoS One.It is believed that artists had a very superficial understanding of how animals use their limbs to move, until 1887. This year, the famous American photographer Edward Meybridzh (Eadweard Muybridge) produced a multivolume work on the movement of animals, which systematized the data obtained in the study of images of walking or running quadrupeds.

During the construction of the coastal cities, we must remember that in some places the wave can be accelerated by 100 times. In relation to climate change is especially important. Scientists have recreated a city in miniature to model the tsunami hits the shore, and found that the building can exacerbate the incoming flow of water. The findings, presented yesterday at the annual meeting of the American Geophysical Union, said that even if the city as a whole is able to withstand the huge waves, some of the buildings and streets concentrated traveling wave, accelerating it to 80 × 100. After Read more [...]
No written evidence does not directly mention the drought as causes of the disappearance of the great Sumerian civilization, but according to the number of indirect archaeological and geological evidence, scientists believe that the fault is it.
According to lead author Matt Konfersta from Ohio State University (USA), the data presented to them at the American Geophysical Union, underlines vulnerability of humanity to climate disasters, including human nature, since they lead to a cascade of unpredictable consequences.

Contrary to previous experiments, NASA officials Alexander Pavlov was able to show that bacteria can live and thrive even at very low atmospheric pressure corresponding to the Martian.If the current Homo Sapiens moved to the current Mars, poor die for many reasons. In the forefront of these manslayers be radical - a hundred times - the fall in atmospheric pressure over the earth. Even whether the Martian atmosphere by chemical counterpart of the earth, it would not be enough for the ventilation of human lungs just because of one pressure. Interestingly, the same results are characteristic of Read more [...]
It was found that the heart muscle of mammals capable of complete regeneration. Surprising results obtained by American doctors during the experiments with newborn mice.Attempts to regenerate damaged human heart ever succeed. Such optimism stems from experiments carried out under the direction of Enzo Porrello (Enzo Porrello) of the University Medical Center in Dallas, Texas (University of Texas Southwestern Medical Center in Dallas).
Doctors removed newborn mice of the heart - about 15 percent. They grew their lost. Full recovery took 21 days. At the heart is not restored any traces injury. Read more [...]
