Biotransistor for biocomputers

The "transcriptor" (transistor based on transcription) is made of DNA and enzymes: RNA polymerase, which performs transcription - synthesis of RNA on a DNA template, and integrase, which regulates the "current strength" – the intensity of RNA synthesis.

Microflora transplantation instead of gastric bypass

Gastric bypass surgery helps gluttons lose weight. But you can do without surgery: transplanting mice with the "right" community of intestinal microorganisms led to a significant reduction in the amount of adipose tissue and rapid weight loss.

Treatment of Down syndrome: the target was found, it remains to get into it

In mice with Down syndrome, in whose brains the human protein SNX27 was introduced by gene therapy, an increase in the number of glutamate receptors and normalization of brain functions were observed. However, the use of such a technique in relation to people is still far away.
