The size of the proton has puzzled physicists

Physicists had measurement of the size of the proton, the results of which were again different from the results of other methods, and the reasons for these differences are still not clear. Article scientists published in the journal Science, a summary of its results NatureNews.To measure the size of a proton (or rather, Zemach radius of the particle) the researchers used a laser spectroscopy. First, hydrogen-1 (consisting of only two particles: protons and electrons) irradiated with muons. According to the standard model, the muon-neutrino are close relatives of the electrons.As a result of Read more [...]

People in many anatomic relationships are not suited to being a people.

People - the most successful primates in the world, but our bodies do not give the Grand Prix for good design.This is a summary of one of the sessions of the annual meeting of the American Association for the Advancement of Science, where anthropologists with hypotheses and analysis of fossils tell about the adaptations that change the body, originally adapted to life in trees. "Our anatomy was not created from scratch, - Jeremy said Desilva from Boston University (USA). - Evolution works with tape and paper clips. "Shin-splints - pain in the muscles of the front of shin after excessive Read more [...]

Scientists have considered the possibility of treating autism parasites

U.S. researchers are studying the possibility of treating autism using highly questionable, and even apparent repelling treatment. Scientists believe that the fight against autism need to ingest parasitic worms.Therapy parasites slowly but surely proving its effectiveness in the fight against autoimmune diseases. And more and more patients ingest the eggs of worms. The basis of this treatment is still considered an alternative, the hypothesis that the "bad" organisms actually protect the immune system from "overheating." For example, in the 19th century, people did not take Read more [...]

Kamchatka scientists have created a working model of a volcano

Volcanologists Kamchatka created a working model of a volcano. The height of a five-story house, it reproduces the natural processes that occur during the eruption. Only molten magma replaced water. Say something similar to the installation of an artificial heart. Manmade volcano with a natural beauty, of course, does not compare, but science is not the point. It is important that vibration sensors at the outpouring of water the reflected curve, which coincides with the data of seismographs recorded during bursts of activity at the volcano Klyuchevskaya. Such experience Kamchatka volcanologists Read more [...]

Bacteria can alter human cells

Scientists first to show that bacteria are able to reprogram cells, turning them into a kind of moving stem cells used to penetrate the muscular and nervous systems. The experiment was conducted on mice. In the study, researchers introduced bacteria in glial cells of the brain that are responsible for supporting neural connections. In just a few weeks the bacteria were able to change the biochemistry of these cells, acting on their "baby" genes and turning off the "adult." As a result, glial cells were transformed into stem. "Immunity does not attack the cells that Read more [...]

Cancer — genomic malignant degeneration

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 [...]
