Inheritance with a burden

In a new paper, scientists have found that in modern humans, Neanderthal genes increase the risk of depression and allergies. But other studies have found Neanderthal genes that have brought people considerable benefits.

Surnames and Y chromosomes in Spain

Spaniards with rare surnames are distant relatives, as are men in many other countries. But it also happens the other way around – for example, in Ireland.

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.

Genes and intelligence: new data

The appearance of additional copies or the deletion of a certain section of chromosome 16 in human DNA is associated with a significant (up to almost a quarter of the norm) drop in IQ.

Michurinsky epigenetics

The graft does not just take root on the rootstock plant, but also actively exchanges epigenetic information with it. The scale of this process has been greatly underestimated before.

Thanks to grandmothers for "longevity genes"

Grandparents turned out to be so important for the survival of the human race that special gene variants appeared that protect people from Alzheimer's disease and other age-related diseases.

Obesity caused epigenetic changes in sperm

Healthy men and obese patients have a large number of epigenetic differences in all body tissues, including sperm. The latter can directly lead to the transmission of the tendency to obesity to children.

Have the tardigrades been slandered?

Biologists from the University of Edinburgh have discovered that the massive borrowing of foreign genes, traces of which were recently allegedly found in the genome of slow walkers, may actually be the result of pollution.

Epigenetics of depression

The reason for prolonged depression may be that anti-stress genes cannot start working because of the "soporific" epigenetic tags on their DNA.

The mechanism of DNA self-packaging

Russian scientists have managed to show how the DNA-protein fibrillation itself fits into a three-dimensional structure. The conclusions made by the researchers can serve as a basis for important practical developments.

Other people's genes help us live

The hardiest and most tenacious creatures on earth – the so-called tardigrades, small invertebrate creatures measuring a millimeter, could become owners of this title thanks to the abundant "borrowing" of DNA from bacteria, fungi and plants.

Hot Finnish mutants

Geneticists from Helsinki found out that a mutation in the 5-HT2B gene makes some Finns prone to aggressive behavior after they have drunk a large amount of alcohol, as well as more impulsive when sober.

How many mutations are there in a cancerous tumor

The genetic diversity of a cancerous tumor turned out to be much greater than it was according to the most daring calculations – there may be about a hundred thousand mutations in a three-centimeter tumor!
