Don't lose the brake light!

The loss of stop codons on mRNA leads to the formation of long lysine chains at the end of synthesized proteins. When the protein quality control mechanism is violated, defective proteins accumulate and form toxic aggregates.

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.
