Scientists have figured out the molecular mechanism of axon myelination

Scientists have figured out the molecular signaling mechanism that triggers the buildup of "electrical insulation" in neurons. This, in turn, has a beneficial effect on the capabilities of the central nervous system (CNS), in particular the brain.

Scientists have identified the reason for the lack of ability to regenerate heart muscle cells

Stem cell researchers at the University of California, Los Angeles have discovered why adult heart muscle cells, called cardiomyocytes, have lost their ability to proliferate, and may explain why the human heart has such limited regeneration capacity.

The future of the embryo can be predicted by the pattern of movement of the egg cell

Immediately after fertilization, the cytoplasm of the egg begins to move, and the nature and speed of the cytoplasmic pulsation can be used to determine whether the embryo will be viable.

Scientists have identified a gene that regulates heart rhythm

Researchers have identified a gene that affects the quality of intercellular contacts in the cardiac conduction system. Disruptions in its functioning caused a mismatch and poor propagation of the neuromuscular signal in the cardiac muscle.

Culturing stem cells in the lab will overcome immune rejection of organs

Pre-cultivating these cells in the lab for about a week may help overcome one of the most difficult obstacles to successful transplantation: immune rejection.

Biologists have discovered a protein that may be responsible for the phantom sensation of bitterness

Biologists have discovered a protein that interrupts molecular signals of bitterness. If taste cells do not have this protein, animals and humans cannot get rid of the unpleasant aftertaste.
