The Y chromosome is the engine of evolution

The Y chromosome has traditionally been considered a weak point of male organisms, reducing genetic diversity and hindering evolution. However, recent studies have shown that fears about the extinction of the male gender are greatly exaggerated.

The genome in Russia is bigger than the genome

The pathos of the "Russian human genome" is not very clear. There is already an international scientific project to decode thousands of genomes of people of different nationalities. Well, now there will be a thousand and one genomes.

GATA-1 – Gene traffic controller

The GATA-1 gene plays the role of a universal regulator of the work of other genes. Scientists have found 2616 genes that, in response to the addition of the encoded GATA-1 protein, begin to work either at least twice as actively, or, on the contrary, reduce activity.

Genes of aggressiveness – a mitigating circumstance?

An Italian court has reduced the sentence for murder after the defendant was found to have "aggressive genes". Lawyers around the world are increasingly trying to use MAO-A deficiency and similar genetic factors to protect the accused.

Schizophrenia, autism and genetics

Psychiatrists and geneticists have found that doubling a small area on chromosome 16 increases the risk of developing schizophrenia by 8 times. Medical genetics has already encountered this site: its removal leads to the development of autism.

Personal genomics: it's time to put things in order

Predicting predisposition to diseases based on individual DNA characteristics will soon become a routine procedure. But the work of companies engaged in the analysis of personal genomes is not standardized enough and needs improvements.

The gene of the quick mind

The difference in the speed of thinking due to the "correct" allele of the COMT gene is small. But the variants of this gene differ by only one nucleotide, and the molecules of the corresponding protein differ by one amino acid.

Genome and diseases: counting copies of genes

Predisposition or resistance to diseases is largely due to differences in the number of copies of the corresponding genes. A new study has added a whole dimension to the space of understanding such variations in the human genome.

History of genomics. Part 2: DNA technologies

The improvement of sequencing technologies and even more so DNA adjustments will give rise to new social, ethical and philosophical problems. The development of DNA technologies is inevitable, and someday they will become available (if not mandatory) for everyone.

History of genomics. Part 1: Genomic projects

The story of how the first methods of reading genetic sequences appeared, what they were and how genomics moved from reading individual genes to reading complete genomes, including complete genomes of specific people.

A genetically diverse brain

The cells from which the human brain is formed undergo genetic modifications during development. Perhaps this is how human individuality is ensured: even in identical twins, the brain is built from genetically dissimilar cells.
