Russian scientists are preparing to establish the production of human organs

The device of the 3D Bioprinting Solutions company is still in the assembly process and should work closer to summer. But instead of one nozzle, which puts bio-ink on the bio-paper, he will have five at once. This means that Russian scientists will be able to print an organ consisting of five types of cells.

The elixir of youth instead of a pill for old age

An application has been submitted to the Ministry of Health for the start of clinical trials of SkQ1 solution for oral administration – the substance feels better in liquid form. So pills for old age, alas, will not work. But it can turn out to be an elixir.

CB3 peptide against "sugar inflammation" in the brain

Elevated blood glucose levels stimulate inflammation in the brain, which can result in the death of neurons. By suppressing the molecular signals associated with inflammation in nerve cells, we can prevent their death.

Gamers helped scientists again

The online game EteRNA united the efforts of 37 thousand amateurs who solved two-dimensional puzzles related to the assembly of RNA molecules. The results obtained made it possible to develop a computer algorithm that is much superior to existing ones.

Cleaning ancient genomes

The creation of a system for separating contamination from DNA will allow geneticists to conduct a more accurate analysis of gene samples of ancient people and animals, which means that it will bring them one step closer to deciphering the secrets embedded in the DNA spiral.

The Fool 's Gene

For about 10,000 years, humanity has been eating genetically modified foods. For several hundred years, such products can make up to 100% of the diet. A few years ago, humanity began to understand exactly what it modifies in genes.
