Proteins from non-natural amino acids: the beginning of the path

A new direction of synthetic biology is the creation of fully "customizable" proteins. The ribosome, which reads not three, but four nucleotides at a time, allows the use of more than 250 non-natural amino acids for the design of biopolymers.

Cells hanging in a magnetic field feel at home

Cell culture grows much better in a three-dimensional matrix than on a flat surface of a Petri dish. But instead of using a porous gel, magnetic nanoparticles can be introduced into cells and suspended in the thickness of the nutrient medium using a magnet.

Microchimerism: alien cells among their own

However, there are probably very few foreign cells in our body – according to estimates, about one in a million. Therefore, researchers have come up with a special name for the phenomenon – microchimerism.

Pharmacogenomics and Pharmacoeconomics

Genetic testing for warfarin tolerance costs about $250, and a monthly course of treatment costs less than $ 6. But a decrease in the number of hospitalizations due to an overdose of an anticoagulant repeatedly recoups the cost of testing.
