Possibly you can't avail it if you ne'er pass to the gym. Researchers at the University of Missouri deliver base that genes may gambling a purpose in motive to exercising, leastways in rats.Weenie Kiosk and Michael Roberts set rats in cages with track wheels, and metric the come of clip the rats worn-out on the roll terminated six years. They bred the 26 top runners with apiece former and the 26 least fighting rats with apiece over-the-counter, repetition this complete 10 generations to make "superintendent contrabandist" rats and "put murphy" rats.The near meaning dispute Read more [...]
The native peoples of North East Asia detect genetic adaptation to cold. Tourists do not like Siberia, yet people are living there for thousands of years. How do they do it?
A new study by the indigenous peoples of Siberia showed how natural selection helped to adapt to the northern cold. It was also found that different populations did it my way.

Siberia occupies about 10% of the Earth's land, but it is considered his home only about 0.5% of the world population. This is not surprising: the average January temperature is -25 Read more [...]
DNA of American shooter Adam Lanza, a bloody massacre at the school in Connecticut, examined for mutations in genes television reported ABC.U.S. researchers examined the DNA of Adam Lanza to determine whether there was a mutation in his genes, which could provoke a massacre at the school in Connecticut, which he had made in mid-December, RIA "Novosti".Research will be undertaken by geneticists at the University of Connecticut, with the assistance of forensic commission staff. Scientists will study the molecular structure of Lanza for abnormalities and mutations of DNA in cells, which Read more [...]
No two people are alike, say thanks for this genetic diversity. Although the color of the skin, hair, or the proportion of the bodies of two people can be exactly the same, you can be sure that their faces will be unique - even identical twins, if you look closely enough. While lifestyle, weight, diet, accidents, and other factors affect the shape and general features, such classical elements as skin color, facial hair, the distance between the eye sockets, symmetry, cheekbones, and so on - completely determined genetically. With this in mind, having an accurate map of the genome, scientists Read more [...]
According to The Courier Mail, the researchers examined a remarkable ability snails almost completely stop aging for a period of hibernation. Now experts want to find the genes that allow the snails to deal with over time. Perhaps the positive effects of these genes actually broadcast and on man.Dr. Scott Cummins, a molecular biologist at the University of the Sunshine Coast, said: "In this way, some snails can prolong his life from age 3 to 23. Dragging it in person, the duration would increase from 70 years to nearly 500."Now Dr. Cummings attempts to identify genes and neurohormones, Read more [...]
Scientists of the U.S. found 24 new changes in the DNA that are associated with autism. Geneticists say that this finding could be the basis for new diagnostic tests.
According to the researchers, each of the identified variations are fairly rare, but more than doubles the risk of developing autism spectrum disorder support, which includes the actual autism (Kanner's syndrome), Asperger's syndrome, childhood disintegrative disorder, Rett syndrome and non-specific pervasive developmental disorder ( or atypical autism).
"Many of these changes in the genes can be valuable prognostic Read more [...]
Experts came to this conclusion based on the largest study in history of the genome of pigs. Scientists were able to decode the complete genome of a pig, and it turned out that these animals suffer from the same disorders and dysfunction of the proteins that trigger diseases such as obesity, Parkinson's disease and Alzheimer's disease. Experts believe - is the key to creating new methods of treatment of human diseases.The length of the domestic pig genome is about 2.6 billion base pairs. He is 40% composed of repetitive DNA segments and contains nearly 22,000 genes. Pig has 39 types Read more [...]
During embryonic development of its agencies must conform to the size of the body and the size of each other. It is clear that one vertebra should overtake its neighbors and become the size of the entire spine. That is, in the growing embryo is a constant scaling of the body, from the smallest to the largest. As it happens, the scientists were able to see from the European Molecular Biology Laboratory (Germany).

Scientists from the University of Warwick have found genes in plants that contain the secret of why some genes in the evolution of "off" and the other "on", and vice versa. This discovery will accelerate the study of plants and in the future will help to solve the problem of food security.
Regions of DNA that are more than 100 million years, are involved in the management of the expression (activity) of other genes of the plant. Simply put, they once moved to the "on" or "off" certain genes that help or hinder the plants adapt to specific environmental 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 [...]
One of the greatest mysteries of mankind - this question of where, in fact, come from humanity itself. Religion and science are arguing about this for a long time, but maybe the truth is somewhere in the middle ...

The Bible says that God created the earth, animals and people - from the dust of the image of God. Darwin's theory, which we passed through a school as absolute truth, says that man evolved from apes. But during the life of Darwin, his theory was subjected to strong criticism, and since its introduction, it is just a theory, but not the ultimate truth.

Doctors have found evidence that a rare disease - progeria, premature aging, due in some cases, not so much by mutations in the DNA as the inclusion of the wrong genes are needed. Children Progeria, she Hutchinson-Gilford, very rare, doctors know less than one hundred cases of the disease. But it is quite well known among both scientists and the general public - because it is a premature aging. By the age of two to three years, the child begins to age, and life expectancy with progeria is only 13 years old. Atherosclerosis, changes in the joints, liver spots on the skin thinning, increased Read more [...]
From whatever side you look - environmental, social, economic, the situation in the world is crazy.
Of course, no "normal" one does not set, and yet, any sane person can imagine it. Norm - this is when the majority of all stability. That is, of course, some people have (in the minority) to the stability of not so good, some people have (from the majority) are bad times, but in general, and generally have confidence in the future. This is normal. About as stable table: anyone who puts on a glass of water, I'm sure he did not suddenly fall off the table and a glass of water Read more [...]
Population - Is aggregate individuals of one species that occupy a certain, strictly limited habitat, ie, are part of the ecological community (see) or parasite (see). For the free-surface and water forms the border of territorial distribution, ie, area, due to the peculiarities of climate, topography, etc., for the forms of parasitic barrier settlement - their life cycle and specific fitness (relative to the host organisms). The study population is conducted from the standpoint of environmental and genetic. Ecology is the study tools that ensure survival of the species and the mechanisms of Read more [...]

Gradually accumulating evidence to convince researchers that the key events in the development of cancer to be found in changes in cells - progenitor of cancer. Studies conducted in the 70's, it was shown that the transfer of DNA from tumor cells is accompanied by the acquisition of the latest healthy malignant properties. Information on the phenotype of cancer cells, as it turned out, is contained in the individual molecules of DNA, and therefore the malignant process supported by the work of genes and only in part - other components of the cell.
