Infarction cell therapy: the largest study

In an international clinical trial, three thousand patients will receive an injection of stem cells (along with stenting of coronary vessels). Doctors believe that this can increase the survival rate after a heart attack by 25%.

In situ RNA sequencing

Biologists led by renowned geneticist George Church have created a method of in situ RNA sequencing ("on the spot"), which allows you to map the expression of thousands of genes on a scale from the subcellular level to the whole brain or embryo.

GMOs in Russia: educational program for senators

Over the past 10 years, more than 1.5 thousand studies on the safety of GMOs have been published, and no conclusions have been made about their toxicity or any negative properties. Russian senators don't want to know.

The relationship between aging and sleep quality is revealed

Researchers at the University of Pennsylvania have discovered the intersection between the signaling cascades of the aging process and the body's response to cellular stress, which, among other things, causes senile sleep disorders. Perhaps the effect on the corresponding molecular mechanisms will help the elderly suffering from insomnia.
