DNA sequencing: cheap or accurate?

A promising method of DNA sequencing based on stretching DNA through a nanopore has not fully justified itself. The data obtained with its help still has to be checked by other sequencing machines.

Anti-aging treatments for muscle stem cells

Aged muscle stem cells can be extracted from the body, rejuvenated in the laboratory and returned back – and after that, almost youthful strength will return to the old muscles.

GDNF is a new target for the treatment of parkinsonism

Endogenous neurotrophic factors produced by the body itself, including glial neurotrophic factor (GDNF), contribute to the survival of nerve cells in neurodegenerative diseases such as Parkinson's disease.

Poisoned bait for glioblastoma

With the help of polymer-synthetic imitation of nerves and blood vessels, glioblastoma cells can be forced to "emigrate" from the brain into a special container filled with cyclopamine gel, toxic to cancer cells.

Analysis of encrypted genomes

Microsoft cryptologists have developed an algorithm for encrypting DNA sequences, which allows them to be analyzed by traditional bioinformatic methods and at the same time does not compromise the owner of the genome.

Sometimes soft is better than hard

The body's reaction to a foreign body depends not only on its chemical properties, but also on its physical ones. An inflammatory reaction to the implant may occur due to the fact that it is tougher than the surrounding tissues.

Genomic surgery

CRISPR and other new technologies make it possible to edit specific DNA fragments with high accuracy, up to the replacement of one pair of nucleotide bases. In fact, they allow you to rewrite the human genome at will.
