Do free radicals slow down aging?

Reactive oxygen species, the harm of which mountains of scientific articles have been written about, turned out to be just as necessary for the body as, for example, cholesterol. A small but constant dose of free radicals is exactly what helps the body cope with premature aging.

Induced pluripotent stem cells for gene therapy of hereditary diseases

Belmonte and his colleagues restored a genetic defect in patients' fibroblasts and turned them into induced pluripotent stem cells. Taking into account the fact that bone marrow transplantation is a proven technology, and there is not much choice in patients with Fanconi anemia, the introduction of the method will have to wait less than gene therapy for other diseases.

Cheaters in white coats

About 2% of scientists report that at least once they invented or falsified their data in order to demonstrate not the real, but the desired result. Another 34% of scientists reported that they had committed "minor" frauds once or more often. Most often, specialists in the field of medicine and pharmacology confessed both to their misdeeds and to what they knew about the falsifications of colleagues.

Mice with a human "speech gene" squeaked in a bass voice

The "humanization" of mice with the help of the Foxp2 speech gene does not affect them in the best way. Rodents become more passive and get less pleasure from life. But the processes of their nerve cells become much longer and more active, complicating the structure of the brain.

Are induced pluripotent stem cells ready for use?

Scientists have managed to obtain induced pluripotent stem cells from human skin cells without the use of foreign nucleic acids or proteins. The technology is based on the use of four modified proteins obtained using human cell culture.

Exposure to "secondary genes" – a new approach to cancer treatment?

In the process of their development, cancer cells develop so-called secondary dependencies in relation to the work of genes that do not cause cancer by themselves. Disorders in the work of these "secondary" genes can be fatal for cancer cells, which can be used to create anti-cancer drugs of selective action that are safe for healthy tissues,

Nanotechnology in Russia: learn from the mistakes of others

The lessons of foreign nanoboom are valuable practical experience for the development of nanotechnology in Russia. Ignoring the accumulated facts can lead to very deplorable consequences, which we would like to avoid through far-sighted planning of all scientific, technological, economic and social aspects of the development of nanotechnology in our country.

The altruism gene

Some variations in the nucleotide sequence of the OXTR gene encoding the oxytocin receptor are directly related to the tendency of people to do good deeds to the detriment of personal gain. The discovery was another step in understanding the hereditary foundations of altruistic behavior.

Dreams and realities of Russian science

From the point of view of the "Parkinson's laws", the state of the Russian Academy of Sciences sounds like a verdict: "Nothing can be done at the third stage. The institution has practically died. It can be updated only by moving to a new location, changing the name and all employees."
