There are no "regeneration genes" in humans:(

Only newts (and possibly other amphibians) have hundreds of genes supposedly involved in the regeneration of damaged tissues. They are not found in the genomes of other vertebrates.

Anti-alcohol nanocapsules

Mice who ate alcohol with nanocapsules with enzymes that break down ethanol to acetic acid sobered up much faster than their drinking buddies from the control group. The authors of the work plan to add a third enzyme to the nanocapsules that removes the symptoms of a hangover.

"Mosquito net" for the flu virus

A new experimental drug prevents the flu virus from entering the cell, allowing the immune system to stop its spread through the body. The artificial origin of this neuraminidase inhibitor reduces the likelihood of resistant strains.

Reprogrammed cells will help with diabetes

Diabetes can be cured by converting its own alpha cells, which are also part of the endocrine apparatus of the pancreas, into insulin-producing beta cells.

Stroke: a new strategy for protecting neurons

The human and mouse brains are protected from the effects of stroke by the hamartin protein, which causes neurons to "eat" part of themselves, receiving energy and oxygen, which allows them to live for several tens of minutes without access to blood.

Rapamycin target: study continues

Scientists at the University of Basel have identified more than 300 new proteins that are targets of mTOR. In particular, the researchers found out exactly how the mTORC1 protein complex controls cell growth and division.

Electronic retinas are being improved

The Alpha IMS wireless bionic retina works without an external camera, providing free eye movement, and sends signals from 1500 pixels to the nearby neural layers of the retina and to the optic nerve, completely simulating the work of photoreceptor cells.

Three-dimensional printing of auricles is getting closer to the clinic

The quality of the artificially grown implant was proved by the authors of the work during experiments on mice. Unlike the auricles that do not contain cellular material, the ears made with the help of 3D technologies did not deform over time and perfectly took root.

They live longer in the cold

A decrease in the ambient temperature triggers a cascade of reactions in nematode cells, the ultimate target of which is the "longevity gene" DAF-16/FOXO. A similar mechanism exists in the cells of warm-blooded animals, but whether cold is able to prolong human life is still unknown.

Geography of the brain: details

In the USA, the Brain Activity Map project will be launched – a project to create a complete map of brain activity that will reveal the biological mechanisms of consciousness and the secrets of mental illness.

Blood, epigenetics and aging

As hematopoietic cells age, changes in the epigenome – the system that regulates gene expression – disrupt their work, which leads to a weakening of immunity, anemia and an increased risk of developing some malignant blood diseases.

Gene therapy of fractures

The healing of fractures and fractures of bones will be accelerated by a paste with synthetic nanoparticles based on calcium phosphate, in which two genes of growth factors that stimulate the formation of bone tissue and blood vessels are encapsulated.
