See thoughts: details

The fantastic experience of Japanese scientists opens the way to recognition in the human brain and those images that he has never seen in reality – dreams or imaginary worlds. Just imagine the work of an artist or designer who just sits in an armchair and, closing his eyes, comes up with images that immediately appear on the computer screen.

Diabetes comes at night

Three research groups have found a genetic link between the development of diabetes, obesity and circadian rhythm disorders.

Swallow a team of doctors

A unique system of micro robots has been developed that can perform a surgical operation.

Kinesin – step by step

Scientists from the Massachusetts Institute of Technology have determined how the movement of protein molecules in the cell-motor – transport protein kinesin.

Insidious test tubes

Perhaps many of the problems faced by geneticists and microbiologists when growing cell cultures in the laboratory are due precisely to the influence of the test tube material, due to which some indicators may differ from the correct ones by dozens of times!

A word about the genetics of behavior

It is clear that practically nothing is yet clear in the genetics of behavior. However, it is also clear that psychologists will soon have to arm themselves with modern tools for analyzing the genetic characteristics of the participants in their research, in addition to outdated Eysenck tests and other questionnaires.

Genes and behavior: humans are just like butterflies and birds

To solve the world's problems, we use old, proven genetic and neural circuits that have evolved over the course of evolution to regulate our relationships with fellow tribesmen in small collectives. And if so, then it's time for political scientists to join forces with specialists in behavior genetics, neuroscientists and evolutionary psychologists.

Exoskeleton for hard workers and old people

The main goal of the creators of the Walking assist portable exoskeleton is to give the joy of movement to old people who are still able to walk, but already with difficulty. And the second purpose of cyberstans is to equip workers on the conveyor.

Placebo: the most important pill

This medicine can help with colds, headaches, ulcers, alcoholism, depression and many other diseases. Its cost price is literally pennies. However, officially this drug cannot be bought in any pharmacy in the world ... We are talking about a placebo — a dummy that the human psyche perceives as a medicine.

Eraser for memories

If the "erasure" of memories ever becomes possible, it will require a careful prediction of the consequences and the development of a solid ethical framework that defines the scope of the technique, since there are plenty of obvious opportunities for abuse of it.

Prick and forget

If the script of the movie "Men in Black" were being written today, the characters of Will Smith and Tommy Lee Jones would be armed not with a flash, but with a genetic vector and a small pill. American and Chinese neurophysiologists have learned to delete unnecessary memories in this way – but so far only in mice.

Nobel Prize – for HIV and the papilloma virus

The 2008 Nobel Prize in Physiology or Medicine will be shared by Harald zur Hausen ("for the discovery of human papillomavirus causing cervical cancer") and Francoise Barre-Sinussi and Luc Montagnier ("for the discovery of human immunodeficiency virus").

Lactic acid is an alternative source of nutrition for the brain

Previously, it was believed that the brain works exclusively on glucose. Using spectral analysis, scientists found that the brain receives not only glucose from the blood coming to it, but also lactic acid, an excess of which is observed in the blood during active muscle work.

Directed assembly of microgels containing cells to create three-dimensional tissue structures

The proposed method of creating three-dimensional tissue structures using a bottom-up controlled assembly of hydrogel microparticles loaded with cells is based on the ability of multiphase liquid systems to minimize the surface area of the phases and, accordingly, the free surface energy of the phase separation.

Just relax!

According to the authors, changes in the activity of the same genes were previously observed in conditions such as post-traumatic stress, but the changes observed during relaxation have an opposite direction and are more pronounced in people who have been practicing relaxation methods for a long time.

Kasparinsky Laboratory

The DVD series "Modern course of lectures on classical Physiology" consists of 12 discs with lectures by famous physiologists of Russia, the highest authorities in their field, who were invited specially for filming from eight research institutes, universities and medical academies from four cities of Russia.

Is group selection coming back?

Where did the author of the "Selfish Gene" and the father of sociobiology disagree, both Darwinists, educators and anti-prejudice fighters? The apple of contention turned out to be group selection.

The brain has become wiser from a good electrical contact

The exchange of impulses (that is, the management of all the activities of living organisms) is carried out through synapses – biochemical complexes responsible mainly for the contact between the axon and the dendrite. Scientists believe that it was the complication of these contacts that contributed to the emergence of more advanced behaviors in mammals, and subsequently in humans.

Ex-Minister of Health of Ukraine: vaccination must be continued!

Why are the media trumpeting a dangerous vaccine in one pipe? Don't be offended – this is provocative journalism. About 120 thousand vaccinations have been successfully made in the country. And there is a tragic case in Kramatorsk, which the whole of Ukraine now knows about. He knows in the interpretation: "Vaccination killed the student."
