DNA segments consisting of four chains were found in the chromosomes of cancer cells, which gives reason to consider such a sign of malignant transformation of the structure.DNA can exist in many forms. For example, can change parameters of the double helix, it may become more compressed or elongated, spiral itself - to be as right-and left-twisted, and the interactions between the nucleotides may be very different from those postulated classical Watson and Crick.Many of the alternative forms of DNA exist in the living cell and needs them for some purpose. But there are others who, it would Read more [...]
External mag, October 1996WildfireA few bright moments in the annals of imbecilityThe summertime of 1996 is ultimately in the books, passing polish as one of the driest and, not coincidently, nearly firebomb on commemorate.

Scientists are looking for a woman who is willing to have a Neanderthal - the first time in 30,000 years. This extravagant idea occurred to Harvard geneticist George Church (George Church), who intends to clone extinct species and is even ready with a surrogate mother to play it to the light, writes "Bagnet" referring to the foreign media."In our lab, kept many remains of Neanderthals. We're trying to have cells that can be cloned. Well, let's say that I was born a healthy baby Neanderthal. Who knows whether he will grow in our environment or sverhumnym superpower? Read more [...]
Such a quality person as leadership, may be an inherited trait. Leadership can be transmitted from parents to children with genes. A team of scientists from different countries conducted a study comparing the genetic samples of about 4000 people. The researchers collected information on work and relationships, establishing a serious relationship between genotype rs4950 and leadership. Scientists from Harvard University, New York University and the University of California estimated the twins, and found that a quarter of the observed changes in the behavior of managers can be explained by genes.

Scottish scientists are planning to see the sea basins antibiotics. This, according to scientists, will help overcome the problem of resistance of pathogens. Scientists working at the University of Aberdeen (Scotland), will take up the study of the deepest ocean trenches. They expect to find there antibiotics. The budget of the project is £ 8 million. The research scientists expect to create depressions medicines that kill bacteria are much more effective than existing drugs. Samples of antibiotics, scientists plan to get in the ocean basins. It was here in the most extreme conditions Read more [...]
Remote clip, December 1995Stocking StuffersBy Amy Goldwasser and Andrew TilinGrivel G10Ultimately, a climber that won't refine your acclivity. The Grivel G10 is as well-disposed to gloved fingers as they get. Amply adjustable without tools, the ten-point G10 attaches with stretchable straps, so thither aren't any buckles to bollix with in the frigid. At just 25 ounces per duad, thither's no rationality not to payoff them wintertime trekking. $92. From Ascent Read more [...]
Scientists argue that a narrow strip of land on the southern coast of Africa has become the last refuge for a group of primitive people who lived through an ice age, destroying species elsewhere. The land, which the researchers called the "Garden of Eden", it may be the only part of Africa, which has always remained habitable during the ice age that began about 195,000 years ago.
Excavations scientists have shown how a combination of rich vegetation on the ground and provided with food movements in the sea created a source of food that could support primitive people during the devastating Read more [...]

The notion that the world came out of the water present in all religions and cultures of the world. All ancient civilizations that arose near water, flourished not only in biological characteristics. Water has affected their way of thinking, art and philosophy. They say the water live mythical creatures that can affect the lives of people. Residents of villages Timbumeri say: - If we look inward, water spirits speak to us, they are still there, deep inside, in a forgotten place where we left their gills. Maybe they're right.Category: Science Read more [...]
on July 17. In South Africa, where the onset of winter is accompanied by a sharp temperature drop and abundant snowfalls, killing two people. Their frozen bodies were found early Sunday morning on the side of the road. According to the preliminary version of the police, victims of the cold steel 44-year-old woman and a 69-year-old man, who could not get home because of snowdrifts.
The temperature in the Western Cape province in those days fell to minus four degrees Celsius, according to ITAR-TASS. On Friday, the national weather service issued a warning about the impending cold weather. It was Read more [...]
Scientists from the UK examined the performance of blood taken from a population of wild birds, and found that using these tests can accurately predict the life expectancy of not only birds, but also humans.
During the test measures the average length of tiny structures at the ends of chromosomes, called telomeres. Know that they are getting shorter each time, when the cells divide throughout the life of the organism.
The experiment was conducted on populations of songbirds living in the Seychelles, according to the journal "Molecular Ecology".
"We found that at any age telomere Read more [...]
In the melting of minerals in the Earth's mantle is crucial carbon dioxide. No, global warming is nothing to do with, since we are talking about processes at depths of hundreds of kilometers.
So deep drill hole is not yet possible, the famous Kola ultradeep well not even reached the design value of about 15 km, to study the inner planets by indirect methods have two different types. Tapping, the analysis of the oscillations in the explosions and earthquakes and simulations in the laboratory. In the journal Nature described a group of American geophysicists is the experimental method - with Read more [...]

on July 19. This year feels Russian agriculture on the strength of all possible ways: first it was cold, then the drought and then the rain turning into a flood. Now it has added to the country's accession to the WTO.
Farmers already compare the current year with the catastrophic 2010, when the unprecedented heat wave and fires destroyed large part of the crop. This time the trouble began in the winter: in the southern and Central regions of long standing cold. Because of this, for example, in the Stavropol territory in the spring forecast of grain harvest was reduced by 30% compared to last year. Read more [...]

Science gets more evidence that the natural environment can positively influence on human health. Environmental disaster, the disappearance of 100 million trees in the East and Midwest of the United States, despite the awfulness of the situation, at least something has been useful, allowing scientists to understand how the major changes in the environment are to our health.Emerald Beetle Podosesia fraxini sawfly was first discovered near Detroit in 2002.

Contrary to the fact that all the Jews of Europe goes back to the people of ancient Judea, genetic research has revealed that a mosaic of DNA of this nation.Despite numerous genetic studies, the origin of the Jews of Europe is unclear. Another analysis, conducted under the direction of Eran Elhaika at Johns Hopkins University (USA), said that the Jewish genome is a mosaic of Caucasian, European and Semitic material.Contrary to popular belief that modern European Jews - direct descendants of immigrants from the Jews, the new data strongly support the Khazar hypothesis.The Khazar empire in the Read more [...]
Maybe we all Neo living in a simulated universe?If our universe is just a model, similar to the Matrix, could we ever know? Silas Bean physicist at the University of Bonn in Germany thinks he knows the answer to this question. The magazine «Physical Review D» published his article "The limited universe as an example of numerical simulation."
Justin Mullins: The theory that we are living in a simulated world is just science fiction, right?
Silas Bean: In fact, there is a strong argument in favor of the fact that we do live in a simulation. The idea is that in the future people will Read more [...]
The study showed women 53-100 years 1837, removal of the ovaries increases the likelihood of mental decline in old age. Removal is usually in young women due to cancer.
