Identity of the anonymous donor DNA can be easy to learn, say scientists

The authors evaluated the safety open database of genomes, prepared within the project HapMap, aimed at drawing up a genetic "map" of the world.The identity of people anonymously donated his genetic material for research, you can easily calculate using publicly available information from the banks of genomes and genealogical "social networking", which puts at risk the safety of secrets, say scientists in a paper published in the journal Science. Scientists often attract volunteers to participate in genetic studies in the search for genes associated with the development of congenital Read more [...]

Leadership is passed genetically from parents to children

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.

We each have about 400 potentially dangerous DNA variations

Man is not perfect - so say the sages of all times. And this is not a metaphor, but the most that neither is true. Scientists have found that every inhabitant of the Earth carries genetic variations, implying a predisposition to diseases and abnormal development. However, these defects cause disease is much less common than they should be.Researchers from Cardiff and Cambridge Universities have found that a healthy person has an average of about 400 potentially dangerous DNA variations. But in the study, published in the journal Genetics, says that in reality, a genetic disorder will develop Read more [...]

Twinkle gene determines the growth of the embryo

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).David Spears). "Height =" 389 "width =" 600 ">Rat embryos at the age of about 16 days (photo David Spears).The researchers took the germ cells of mice at Read more [...]

Humanity continues to evolve

It is easy to decide that people stopped in development, but there is nothing further from the truth. Although modern medicine and other blessings of civilization greatly facilitated the struggle for survival, making it almost invisible, evolution is still there. And over the past thousands of years, it could even accelerate.Charles Darwin was in no hurry to declare the existence of a common ancestor of man and apes, giving the right to prepare the public for this seditious thought his followers like Thomas Huxley. Only in "The Descent of Man, and sexual selection" (1871), when the Read more [...]

Scientists: genetic failure as the cause of homosexuality

Geneticists have suggested that the development of homosexuality due to a violation of human DNA in a package, that is the preservation of the embryo epigenetic markers, which he inherited from the parent of the opposite sex. Scientists have presented a new hypothesis in a paper published in the journal The Quarterly Review of Biology. She was nominated member of the University of Tennessee, Sergey Gavrilets, together with its counterparts in California and the University of Uppsala. Until now it was thought that preceded the emergence of homosexuality genetic mutations, however, all attempts Read more [...]

Scientists have found a gene in each individual 400 mutations

Every person carries a 400 genetic mutations. At least two of them are directly related to the symptoms.Scientists have studied the genetic code of 179 healthy people and compared it to the directory of all versions released by mutations that cause the disease, writes Suddeutsche Zeitung."We now know that healthy people have a lot of damaged or completely deactivated protein chains, but it has no significant impact on their health," - says one of the study's authors, David Cooper of Cardiff University.The publication points out that most of the genetic abnormalities do not cause Read more [...]

Birth of a homunculus: to decipher the human genome, scientists will be able to cure all diseases

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 [...]

Scientists have discovered a gene-predictor of the time of death

U.S. researchers have identified a genetic variation that affects the body clock is so strong that it can specify at what time of the day most likely will come the death of a person. U.S. scientists have discovered a genetic variation that can affect the human biological clock, so much so that even can "predict" the time of day when the death for it is most likely, writes The Daily Mail. "Internal biological clocks regulate many aspects of human biology and behavior. They also affect the time of onset of acute clinical conditions such as stroke and heart attack," - said study Read more [...]

Scientists have a new hypothesis about the nature of homosexuality

12/12/2012Geneticists have suggested that the development of homosexuality is associated with disturbances in the packaging of DNA, when the embryo retains epigenetic marks, which he acquired from the parent of the opposite sex. Article outlining the hypothesis published in The Quarterly Review of Biology. Its advanced alumni Sergey Gavrilets, of the University of Tennessee, along with his colleagues at the California and the University of Uppsala.For a long time it was thought that the cause of homosexuality is a genetic mutation, but despite the efforts of scientists, "homosexuality Read more [...]

Evolution of the number two

Religious people believe that life on Earth was created by God, and only he has the right to ensure that "breathe" life in dead matter. However, with the rise of civilization man has repeatedly challenged the Creator, pretending to compete with him in power and capabilities. At the beginning of XXI century, we have come close to the border crossing after which it will be possible to speak of a new era in human history. Our scientists have indeed become like gods, "launching" a new evolution of creatures that might never have occurred in the world without human intervention. The Read more [...]

Rebellion AI

Spontaneous rebellion computer looks more way that came out of a movie than a real possibility, because the AI is not their desires, while man it does not create them. However, some types of AI, for example, are created by using genetic algorithms, is the method of its creation are set to fight and survive. Further, no matter what the main purpose of the AI, he will have one thing in common for all variants of sub-goal - to survive, and thus protect themselves from destruction. And the best form of defense - attack. The most real is the danger that man AI team will not think through all the Read more [...]

Genetic degradation of human

In Section 16.5, we consider the biological aspects of genetic degradation (and the likelihood that it will lead to the complete extinction of the species) and human evolution. Here we should note that the genetic degradation refers to the gradual destruction of the valuable, we believe it is important in a person and what you can, roughly speaking, to identify with certain alleles inherited traits. For example, blue-determined by a recessive gene, and should gradually disappear. Otherwise this risk can be described as risk loss of genetic diversity of humanity. For example, if suddenly humanity Read more [...]

The role of genetic factors

Rheumatism - A complex infectious-allergic process, unfolding in a particularly reactive streptococcal infection on the body, not by chance rheumatism occurs in only one out of 100 sporadic ill with angina and in 3 of 100 ill with angina epidemic. There is increasing evidence of the existence of the "family of rheumatism," the development of which play a role not only hereditary (genetic) and environmental factors (infection, social and everyday moments). The successful development of medical genetic research gives reason attributed to the number of rheumatic diseases arising under Read more [...]

The endocrine system-5

Mechanisms, leading to an increase in insulin secretion, on the one hand, and the resistance to its action - on the other, are studied. However, the main reason for the development of diabetes in obesity is now recognized to consider insulin resistance. In people with obesity decreases the ability of insulin to stimulate glucose uptake and metabolism in insulin-dependent tissues. It is now believed that such a "tissue resistance" to insulin secondary causes development of hyperglycemia, hyperinsulinemia, and eventually diabetes [Salans L. B., 1985]. The nature of the tissue defect Read more [...]

Long live the dream real-1

Is it time to dispel the belief that longevity is determined only by heredity, calm, serene life and favorable climatic conditions? Demographic statistics show that only one out of four centenarians ancestors reached old age. Themselves centenarians - active workers, people who find joy in communicating, in service to high ideals. Many of them - the war veterans who know the terrible hardships of hardship. And of them say that they got easy life - No worries, nervous breakdowns and mental turmoil. But in spite of everything, they do not mind getting older. Mental, spiritual aging does not coincide Read more [...]

Relationship of actual nutrition and health of elderly and old age-4

According to VV Frolkis Bogatskaya and LN (1967), in old age there is a lack of substrates in the third stage of energy transformations. In other words, despite the fact that the nutrients ingested in large amounts, they can not be absorbed and incorporated into the citric acid cycle, creating a relative lack of substrate. Moreover, in old age is a redistribution of substrates used in the energy needs of the cell. For example, significantly reduced the ability of the oxidation of fatty acids (AA Pashkov, 1965). Thus, with high caloric diet substrates can not be used and, in turn, may inhibit Read more [...]
