Too slippery for bacteria

American and British scientists have developed a group of polymer materials on the surface of which bacteria cannot gain a foothold and, accordingly, biofilms are not formed.

"Selfish" DNA will help to study the aging process

Roundworms have been found to have "selfish" mitochondrial DNA that causes premature aging of cells. These molecules are a promising model for studying human aging processes at the molecular and cellular level.

Against everyone!

An antibody active against all types of influenza virus has been found. It attacks an element common to all strains, forbidding the key protein of the virus to change shape and thus blocking the penetration of infection into cells.

Cell therapy: Japan rushes into the lead

The pioneer of stem cell research Shinya Yamanaka intends to create a bank with dozens of lines of induced pluripotent stem cells. As a result, Japan will be able to become the foremost biomedical research leader for the first time.

Alzheimer's disease: two good news

Replacing one nucleotide in the ARP gene reduces the likelihood of Alzheimer's disease by 7.5 times. And the first signs of beta-amyloid accumulation are found in the cerebrospinal fluid 25 years before the onset of the disease. Perhaps the failures with the development of anti-Alzheimer's drugs are explained by the belated start of their trials.

Telomeroreductophobia

Women with phobias are noticeably older than their peers who are not afraid of spiders, mice, etc., according to such an indicator as telomere length. We hope that this publication will not lead to the appearance of another phobia – the fear of shortening telomeres :)
