Inverted viruses

For a long time it was believed that endogenous retroviruses do not perform any functions. But a new study shows that our body has turned some of them into weapons against modern viruses.

The role of mitochondria in cell aging

An international group of scientists has managed to decipher the mechanism by which mitochondria contribute to cell aging. One of the main factors of senescence is the process of formation of new mitochondria.

How important genes turned out to be unimportant

Pakistanis living in a closed community in the UK often lack genes, the absence of which is associated with serious diseases. Surprisingly, this did not affect the health of the examined.

The first "graying gene" has been discovered

As a result of genome-wide DNA analysis of a large population of Latin Americans, the first gene responsible for graying was identified, and a number of previously unknown associations of certain gene alleles with the appearance of hair and eyebrows were found.

Microbes are collectivists

Biologists from Duke University have developed a strain of E. coli that can exist under certain conditions only in the form of a dense colony – any bacterium that splits off from the rest almost immediately dies.
