With age, the brain "shrinks"

The volume of the human brain gradually increases until about 40 years old, after which it begins to slowly decrease and by the end of life approximately corresponds to the size of the brain of a 7-year-old child.

Cell reprogramming: better less, yes better

The SNEL cocktail gives fewer iPSC colonies, but about 80% of them pass the toughest pluripotency test – significantly more than the traditional OSKM cocktail, which gives many colonies, most of which, however, do not pass this test.
