Nerve cells are recovering from physical education

Nerve cells are recovering from physical educationNerve cells are recovering from physical education Physical activity has a positive effect on intellectual ability. A group of American scientists from the University of California at Irvine managed to establish the biological mechanisms underlying the effect of training. It turned out that exercise increases the activity of substances that directly stimulates the growth and development of nerve cells. In a study of rats that were allowed to run in the wheel, compared with normal animals. Scientists expect to detect changes only in those areas of the brain that are directly associated with the function of movement. However, the results surprised them. Читать полностью -->

Indigenous peoples of the far North may die because of global warming

Indigenous peoples of the far North may die because of global warmingThe indigenous inhabitants of the North approach States whose territory is adjacent to the Arctic, with a request for cooperation in the fight against climate change. A recent study by experts showed that the effects of rising temperatures will be most serious for the residents of the Arctic. Warming will change the way of life of indigenous peoples of the far North. "Under threat all," says the leader of the Indian Council of the Athabasca Gary Harrison, our home because of the storms and the melting of permafrost, our food - from changes in flora and fauna, our life is because of the traditional tourist routes will be dangerous.". . .

Restorative massage

Restorative massageHigh physical activity in the workplace, in the home, in sports require restorative massage. Restorative massage is applied as part of the rehabilitation measures taken after certain diseases, in particular diseases of the musculoskeletal system. Restorative massage helps to relieve fatigue and tension, serves as a prophylactic measure for the prevention of injuries and diseases. The main objectives of restorative massage to activate blood circulation and lymph flow, removing from the body the products of its life activity, increased muscle tone, normalization of muscle function, activation of the functioning of spinal motoneurons. To carry out restorative massage you need in a relaxed atmosphere in a darkened room, in which there are no extraneous stimuli. When conducting a restorative massage, you should use the techniques of stroking, rubbing, kneading and vibration. Читать полностью -->

Fat does not mean stupid and lazy

Fat does not mean stupid and lazyDoctors are mistaken when they assert that fat people are lazy. This is the conclusion of researchers from Yale University in the USA. Many fat people complain about the fact that people often believe that their excess weight is associated with overeating or because they do not exercise. Meanwhile, obesity may be due to other reasons, such as heredity or environment. Marlene Schwartz and her colleagues conducted a survey of 389 physicians who treat and study obese people. Those who are younger, more likely to suffer from stereotypes about fat people. Читать полностью -->

The blind can see

The blind can seeThe blind can see American scientists have developed responsive to light of a computer chip that could be implanted in the eyes of the blind people, resulting vision will be partially restored. The goal of scientists is to allow people suffering from some form of blindness (e.g., senile degeneration of the cornea) to see 1000 light points with 1000 tiny electrodes placed in the retina. Some diseases that lead to blindness, eye damage cells that turn light into electrical impulses. However, the "path" to the brain, by which these impulses are transmitted, remain intact. The researchers hope that by using the invented chip will be able to send signals to the brain, necessary for the partial recovery of vision. "Our goal is to make it so that blind people could read, walk around the house without bumping into objects, and to perform basic household chores," says project Manager Kurt Wessendorf (Sandia National Laboratories, USA).
