Three, six, code

Two nucleotides are connected by a strong covalent bond, and with the third and the amino acid – by weak physico-chemical bonds. To strengthen this connection, we need another three – complementary. It will turn out to be a six, which will be supported by hydrogen bonds between complementary nucleotides.

microRNA – the further into the forest, the more firewood

microRNAs are involved in the processes of individual development of the body, including temporary control, death, proliferation and differentiation of cells, embryonic laying of organs.

Stem cells: How to distinguish science from myth-making? (2)

I advise you to be wary of representatives of pseudoscience and mythologists who have flooded our scientific space. Stem cells have a huge potential for the treatment of many diseases, but we are still looking for optimal opportunities for their proper use.

Hereditary diseases: it is possible to identify now, to cure – not yet soon

Until recently, mainly monogenic diseases that occur when one gene is disrupted have been studied. But most hereditary diseases are associated with simultaneous disruption of several genes and certain environmental influences.

Stem cells: How to distinguish science from myth-making? (1)

The information circulating in the media that scientists have received the Nobel Prize in Physiology and Medicine for discoveries in the field of stem cells is rekindling interest in mysterious cells, both among specialists and among ordinary people. Since there are already a lot of myths on the Internet and scientists dealing with this problem, there are also a certain number of charlatans who use the moment to earn money and fame.

World Community Grid: Join the Distributed Computing network!

There are about 650 million personal computers in the world, and most of them use only a small part of their power when working. At the same time, these untapped resources can be used for the benefit of all mankind. To this end, in 2004, the World Community Grid system was created – the largest global computing system for solving the most important humanitarian problems.

The best cure for hypertension is sausage!

British scientists (C) have found that daily consumption of nitrates, which are part of beet juice, as well as green leafy vegetables, helps to reduce blood pressure. It would be nice to check the effect on the pressure of sausages, sausages and other conditionally-food products, in which nitrites are added to preserve the pink color.

The case of Growth Hormone

To date, more than a hundred cases of death have been registered in France in young people who were given growth hormone in childhood. Today, 16 years after the first death, the families of the victims are demanding justice at the trial that began in Paris.

Human evolution continues: new evidence

A group of French and Spanish scientists led by population geneticist Luis Quintana-Murzi has discovered new evidence in favor of continuing human evolution.

The shelf of genes has decreased

By the time the "draft" sequence of the human genome was published in 2001, the figure 35,000 was generally accepted, but now genetic catalogs include approximately 24,500 genes. A new bioinformatic study shows that the number of "real" genes is even smaller: about 20,500.

Mario Capecci: features of an individual approach

Mario Capecci has had a fantastic academic career. Today, the knockout method, of which Capecci was one of the fathers, is already a classic of molecular biology.

Biomedicine: How many steps to clone?

Is human reproductive cloning possible? At the Congress, this question received a clear answer: "Yes." It was also stressed that "such a step should be carried out by responsible countries and for the sake of noble goals."

Immunochromatography: express diagnostics in the family doctor's bag

Immunochromatographic express diagnostics is a new high-tech method that allows not only to accurately diagnose a large range of the most serious pathologies (myocardial infarction, dangerous infections, inflammatory processes, oncological diseases, hormonal disorders, etc.) outside of laboratory conditions in 5-20 minutes, but also to assess their severity.

Prostatitis: legends and myths of male disease

The treatment of prostatitis, especially its severe and rare forms, is shrouded in a halo of mystery. Often the disease is associated with such difficulties that in life this diagnosis is carried as a heavy cross.

The Science We've Lost

Wages are lower than in science only in such sectors as agriculture, non-productive services for the population, culture and art, education and forestry. Almost every 13th emigrant is a scientist! The main group of emigrants are programmers, biotechnologists, molecular geneticists.

How Molecular Cell Biology is being Killed

In January 2008, the participants of the Molecular and Cellular Biology program found themselves in the information and budget vacuum zone – no one canceled the program, but also did not extend it, as, indeed, other programs of the Presidium of the Russian Academy of Sciences. Those scientists who believed the seriousness of the promises of the Academy of Sciences and returned to Russia, having received grants for 3 and 5 years, found themselves "in limbo."

Competition of Russian-Austrian research projects in 2009

The Russian Foundation for Basic Research and the Austrian Scientific Foundation announce the 2009 contest of joint Russian-Austrian research projects.

Commendation of Personalized Medicine (1)

By using molecular genetic analysis to achieve optimal medical results in the fight against a disease or a patient's predisposition to a particular disease, personalized medicine can lead to the introduction of new health standards.
