An experimental drug that selectively destroys blood vessels that feed fat cells allowed obese macaques to lose up to 11% of their weight and up to 27% of fat reserves in the abdominal area in 4 weeks.

Erythrocytes "from a test tube": like real ones, only more expensive

France conducted the world's first successful test on volunteers of the properties of erythrocytes grown from stem cells.

Hormesis, cell death and aging

The phenomenon of hormesis may explain the ability of autophagy inducers, such as resveratrol and a low-calorie diet, to increase life expectancy.

Hormesis, cell death and aging: literature

How to become healthy, strong and hardy?

Disabling the synthesis of just one protein in muscle cells made it possible to create super mice – muscular cold-resistant marathon runners, and the absence of the same protein in adipose tissue protected animals from diabetes.

Age and sense of smell

Aging olfactory neurons lose the selectivity of responding to different stimuli. In other words, with age, a person's ability to distinguish different smells from each other deteriorates.

Live to be 150 years old

Academician of the Russian Academy of Medical Sciences Vladimir Shabalin talks about pills against old age, home cancer prevention and technical immortality.

Monoclonal antibodies against psoriasis

The drug Stelara (ustekinumab), which is 100% monoclonal human antibodies, opens a new class of drugs for the treatment of psoriasis.

Diabetes is a blow to the brain

Numerous complications of diabetes, such as kidney disease, trophic ulcers on the legs and vision problems, are well known. However, it turned out that this disease also has a detrimental effect on the human brain.

New old

Compared to their peers who lived 30 years ago, modern old people have sex more often, divorce more often, demonstrate more outstanding mental abilities and, in general, feel better.

I bequeath my heart…

According to the draft law "On the basics of protecting the health of citizens in the Russian Federation", Russian citizens can issue a power of attorney from a notary for the desire to donate their entire body to science after death or give organs for transplantation.

To rejuvenate the body, it is enough to remove old cells

Selective removal of aging cells that have lost their ability to divide slows down the aging of the body and postpones the appearance of symptoms of age-related diseases.

The source of eternal youth was found in the intestines of fruit flies

Selective stimulation of the dPGC-1 gene activity in drosophila intestinal stem cells improved the health of insects and significantly increased their life expectancy.

Be happy, live long!

The feeling of satisfaction, excitement or happiness experienced during a normal day reduces the probability of death of elderly people by 35%.

Rejuvenate old cells to embryonic age

Researchers from the University of Montpellier managed to rejuvenate the cells of the very old to the state of embryonic stem cells. So far, unfortunately, only "in vitro".

The "wrong" FTO gene is not a verdict on obesity

An active lifestyle in people with a "bad" copy of the FTO gene, which contributes to the appearance of overweight, reduces the risk of obesity by 27%.

Check the quality of sperm without getting out of bed!

The device for testing the ability to fertilize allows you to determine the concentration and motility of spermatozoa with a high degree of accuracy at home.

The lungs are also recovering

In two parallel studies, the researchers identified stem cells and a biochemical signal that ensures the restoration of significant damage to lung tissue.

Progeria: gene therapy gives hope

Gene therapy has significantly increased the life expectancy of mice with a progeria analogue. Clinical trials are next in line.

Prolonging life without a low-calorie diet

Aging can be slowed down without limiting calorie intake. The key to slowing down the aging process is to maintain the activity of the Tsa 1 enzyme in cells.
