Genome operations

Molecular biologists from leading American universities have developed a new method by which the genome can be edited. Or, as the authors themselves say, "to do operations" at the genome level.

Cell Reprogramming: a new success

Bioengineers from the Hebrew University in Jerusalem directly, bypassing the IPSC stage, grew trophoblasts from skin cells – cells from which the placenta is formed in the embryo at the earliest stage.

30,000 neurons in a computer

According to the head of the Blue Brain Project, this is not yet a confirmation that scientists are actually able to reconstruct the human brain, consisting of 85 billion or more neurons, but the first step.

Typical Yakut hereditary disease: thoughts about

It is not the number of hereditary diseases that is growing, but the amount of our knowledge about them. It's just that many similar cases went unnoticed before, because there were no diagnostic methods. hereditary diseases,

Gene therapy of aging: experience for yourself

Elizabeth Perish, the head of the startup BioViva, became the first person in the world to receive genetic therapy for aging. According to Perish, we are talking about the activation of telomerase using viral vectors and the introduction of structures that stimulate the synthesis of follistatin.

A new target for the development of male contraceptives

A group of Japanese physiologists and biochemists have learned to reduce sperm motility in male mice using immunosuppressants, "disabling" the motility of the middle part of the sperm (connecting the tail and head).

Experts – about editing the genes of humans and pigs

Editing human genes can form the basis of promising methods of treating serious diseases, but they cause a lot of doubts. Genetically modified pigs as a source of donor organs are of little less concern to specialists.

Stem cells against bone fragility syndrome

A unique clinical trial is scheduled to begin in January 2016, in which collagen-synthesizing stem cells will be injected into unborn children with osteogenesis imperfecta (bone fragility syndrome).

Solving the Peto Paradox

Elephants, despite their size and long lifespan, get cancer less often than smaller species. This paradox was named after Richard Peto, a British epidemiologist from Oxford, who noticed it back in the 1970s.

How Epigenetic Heredity works

The mice conceived with the help of spermatozoa completely cleared of epigenetic marks almost universally suffered from the most serious developmental defects, anomalies in the structure of the skeleton, and many of them did not even live to be born.

Not all video games are equally useful

Analysis of the results of observations of the brain of gamers showed that the best way to develop our nervous system is not puzzles and games for ingenuity, but shooting games and arcades.

238 genes that yeast lives longer without

Almost half of these genes that affect life expectancy are also found in mammalian DNA. In theory, all these DNA sites can be the "targets" that can be hit by life-prolonging drugs.

Synthetic life

Currently, synthetic biology is understood as the creation of new biological constructs and systems, as well as the modification of natural living systems in order to obtain an organism with the desired qualities.

Gene editing will solve the problem of donor organs

Using the CRISPR/Cas9 method, American scientists have modified many genes in pig embryos, which in the future will allow the use of organs of genetically modified animals for transplantation to humans.
