The core of our planet is changing its shape!

Geophysicists have made a sensational statement. They believe that the core of the earth changes its form. According to them, in the Eastern Hemisphere, the Earth's core is gradually melting, and the Western Hemisphere, it hardens. Previously, scientists followed the theory that the earth's core is stable and has a crystalline structure, but this myth dispelled French geophysicists, they argue that the processes in the core of the earth continues, and it has not septenary form. Data on seismic activity going over thirty years, and they have evidence that during this period there were Read more [...]

Scientists have figured out how to decipher the DNA of a single cell

Genome of plants and animals - is not new. However, there is a caveat - this process will take a lot of the body's cells - thousands and millions - after deciphering which scientists are generalized, and therefore, inaccurate views of the genome. Judge the changes in the DNA of individual cells can result. Harvard scientists have found a new way to decode the genome of the individual cells, according to an article on the website Nature. To do this, first get multiple copies of DNA. Existing methods, including using the polymerase chain reaction, are imperfect. They lead to the fact that Read more [...]

A new type of human cell division

Many types of malignant tumors tend to increase the number of times the event of chromosomes in a cell or polyploidy. It is known that, for example, at 14 and 35 percent of breast cancer and gastric cancer, respectively, have a triple or multiple set. (Recall that the normal cells of the human body have a double set of chromosomes). The basis of this phenomenon is a violation of the normal process of cell division - mitosis. Usually precedes mitosis phase synthesis, in which there is a doubling of the genetic material (copy of all forms of cellular components). After that, as a result of mitosis Read more [...]

Blood groups have for virus protection

Scientists believe the University of Bath, a person could buy the enzymes that determine the blood group of bacteria - they were necessary to prevent the spread of viruses in the population. Red blood cells in the blood covered the carbohydrate structure called glyco-antigens. The phenotype of these antigens determine blood group system AB0. A-positive people have antibodies that oppose glycoprotein antigens of B, B-positive have anti-A and anti-0, 0-positive - the anti-A and anti-B. These antibodies do not exist at the beginning of the formation of the body, and appear with the intestinal bacteria Read more [...]
