Postgenomic biotechnologies

The pharmaceutical industry development program assumes that about 200 domestic medicines should be created by 2020. Several dozen of them should be innovative means of a new generation. The creation of such drugs is the main task of the Department of Postgenomic Biotechnologies of the Institute of General Genetics of the Russian Academy of Sciences.

DNA genealogy: Slavs and "Indo-Europeans" (Part 2)

We have sorted out the ancestral homeland of the "Indo-Europeans", who turned out to be Arias, they are also Proto-Slavs. And where is the ancestral home of the "Proto-Indo-Europeans"? What is the picture of the flows, migrations of "Proto-Indo-Europeans" that led to the appearance of the Aryans, the Proto-Slavs in their historical homeland? This is the second part of our investigation.

Eraser for memories

If the "erasure" of memories ever becomes possible, it will require a careful prediction of the consequences and the development of a solid ethical framework that defines the scope of the technique, since there are plenty of obvious opportunities for abuse of it.

Prick and forget

If the script of the movie "Men in Black" were being written today, the characters of Will Smith and Tommy Lee Jones would be armed not with a flash, but with a genetic vector and a small pill. American and Chinese neurophysiologists have learned to delete unnecessary memories in this way – but so far only in mice.

Male organ from one cell

The cherished dream of apologists of tissue engineering has come true: an entire organ of an adult organism has been grown from a single cell by planting it in a kidney. This organ has become the prostate, which cannot fail to interest men. And these developments, although indirectly, concern the weaker sex.

Do our illnesses depend on nationality?

Resistance or susceptibility to certain diseases can be encoded in our genes. And in many ways it depends on the place of permanent residence of the people to which a person belongs. The direction in science that studies this problem is called "ethnogenomics".

DNA genealogy: Slavs and "Indo-Europeans" (Part 1)

Haplogroups and haplotypes do not determine the shape of the skull or nose, hair color, physical or mental characteristics of a person in any way. But they forever bind the carrier of the haplotype to a certain human race, at the beginning of which there was a patriarch of the family, whose offspring survived and lives today, unlike millions of other broken genealogical lines.
