Reprogrammed cells will soon become publicly available

The first human implantation of induced pluripotent stem cells reprogrammed into retinal cells took place in 2013. In case of a successful outcome of the tests, the use of IPSC will become an integral element of medicine.

Schizophrenia: from genetics to psychology

The search for genetic variants that may be associated with an increased risk of developing schizophrenia has been going on for decades. However, to date, all reports of the detection of "schizophrenia genes" have not withstood strict checks.

Senile vagaries of nature

How our ideas about aging have changed, how some theories try to explain aging and its neglect, and why it is so necessary for a person to "disassemble" ageless animals to molecules.

Zika fever: the price of success

The Zika virus has become an international disaster. However, this would have been ignored if not for the terrible feature he acquired at the same time: he probably mutated and now, presumably, causes severe deformities in patients.

Autistic Macaques

Chinese scientists have caused a congenital disease in monkeys, similar to one of the forms of autism in humans. This model will allow to clarify the mechanisms of the disease development and to try out various methods of autism treatment

What did the "lifetime machine" show?

Aging does not have a single molecular cause - it is a systemic process involving a complex biological network. Genetic processes and environmental factors are equally involved in the mechanism of aging.
