Why do follicles age

Geneticists from the USA and Japan have found the cause of baldness in men and some women in old age – it turned out that the stem cells of hair follicles turn into skin cells as a result of damage to their DNA.

Males without male genes

A group of scientists from the University of Hawaii, working with transgenic mice, obtained offspring from a line that does not have a Y chromosome. Moreover, the males of this line did not have a single gene that contains the Y chromosome, and the offspring from such males turned out to be quite viable and fertile.

Aging trajectories

The dynamics of aging is traditionally described with the help of "survival curves", showing what proportion of individuals survive to a certain age. The nature of the dependence of mortality on age varies greatly among different organisms.

Phytotherapeutic geroprotector

Scientists from Japan have found out that the folk drug rikkunsito, used for stomach pains, causes the body to produce the hunger hormone ghrelin, which, in turn, slows down aging by acting on the gene and protein SIRT1.

Hold on to the steering wheel, not the crutch

Scientists suggest that the refusal to drive and the deterioration of health are mutually conditioned: health problems force you to give up driving, and the refusal to drive aggravates health problems.
