Stem cells restored heroin-damaged brain

Israeli scientists were able to restore the brain damaged by heroin use. The introduction of nerve stem cells into the hippocampus restored the structure and function of the organ to mice born to drug-addicted mothers. At the same time, the main work was done by "local" cells, which for some reason were prompted by transplantation to divide more actively.

About the forum and the "scientific form" of Russian nanotechnologists

We have already lost the information revolution, in the sense of "hardware". The next one, the nanobiotechnological one, is happening right before our eyes. Whoever wins it will dictate their terms in the XXI century. Now in the West, a huge number of university groups, laboratories, and companies are working in the field of nanotechnology. And Russia, by and large, is just beginning to move in this direction.

Blood vessels and Alzheimer's disease

A new model of Alzheimer's disease puts its origin in direct connection with the sclerosis of blood vessels feeding the brain. When the lumen of these arteries is closed by fatty deposits, the brain begins to receive less blood and, consequently, less glucose. It turns out that arteriosclerosis is not only responsible for vascular dementia, but also provokes Alzheimer's disease.

Genome: The Autobiography of a Species in 23 chapters

The 23 chapters of the book are 23 human chromosomes. On each one, the author finds some particularly remarkable gene and, starting from it, tells about the origin of life on Earth, about where the soul "hides", about how heredity affects a person's character and abilities, about who is to blame for the fact that a person loses immunity from stress, about where do hereditary diseases and cancer come from…

Fasting does not prolong life

One of the mechanisms of prolonging life with calorie restriction, found in experiments on rodents, is a decrease in the synthesis of insulin–like growth factor-1 (IGF-1). However, as Luigi Fontana and his colleagues have shown, a low-calorie diet does not have such an effect on people.

Crisis: the worst is ahead

The financial crisis seems to have passed, says Anatoly Chubais, the banking system has resisted. The economic crisis is unfolding. Economic will turn into social exactly in the spring. Whether the social will turn into a political one is already a question of the strength of the system that has been built over the past 8 years.

No "genetically modified" girls!

The girl, who will be born any day in the clinic of the University of London, has not been genetically modeled, not to mention the creation of an "artificial gene system" unknown to science. And no one has withdrawn the gene from her, especially since simply "removing the cancer gene" would probably be even worse.

Stem selection

Having "reprogrammed" a skin cell into a stem cell, scientists insisted that medicines for all diseases would be selected individually. Expectations were met: from the skin of a baby suffering from a rare fatal disease, it was possible to create a cell line that allowed us to find the right drugs. However, the doctors did not have time to help the child.

Nanoparticles for medicine

Attaching magnetic nanoparticles to antibodies instead of fluorescent dye molecules increases the sensitivity of detecting marker proteins by about a hundred times. And ultra-fine polishing with the help of liquid suspensions of quartz nanoparticles, which are used for the same purposes in the semiconductor industry, makes the enamel so "slippery" that bacteria cease to stay on it.
