The scientist told about the coronavirus immune to the people

Director of the St. Petersburg research Institute of epidemiology and Microbiology named after Pasteur, academician Areg totolyan noticed that some people were not getting COVID-19.

The scientist emphasizes that this is the case when detailed examination of several doctors, which for several months he worked in the "red zone".

The plastic recycling and sequestration of carbon dioxide

Indian chemists in collaboration with British colleagues have created a nanoporous material, named as amorphous zeolite, which converts carbon dioxide into fuel and plastic from waste chemicals. The study is published in the journal Nature Communications.

Global warming, caused by greenhouse gas emissions, and pollution of non-biodegradable waste — the most important anthropogenic problems the solution of which I think scientists from different countries.

Singapore scientists have created a cure for yellow fever

Singapore scientists have announced the successful completion of the first phase of clinical trials they have developed an experimental drug against yellow fever. The study is published in the New England journal of Medicine.

Yellow fever — a hemorrhagic disease widespread in South America and Africa South of the Sahara, which annually affects about 200 thousand people, from them about 30 thousand die. So far there are no approved treatments for this disease. Although there is a vaccine against yellow fever, it is impossible to give some people because of the risk of side effects.

Scientists have confirmed that before our Universe existed something

American scientists using mathematical tools described heterogeneity of relict cosmic radiation, which arose immediately after the birth of the Universe. The authors believe that their results confirm the correctness of the hypothesis of the Big bounce, according to which the emergence of our Universe was the result of the collapse of a "previous" universe. The results were published in the journal Physical Review Letters.

While the theory of General relativity explains a wide range of astrophysical and cosmological phenomena, some properties of the Universe remain a mystery. In particular, it cannot explain the uneven distribution in space of galaxies and dark matter.

Japanese scientists have found a connection between laughter and health in old age

Scientists of Nagoya University in Japan came to the conclusion that older people who do not laugh in everyday life, the risk that subsequently they will not be able to serve themselves and they will need outside assistance increases by 1.4 times. About the study and the reasons of this phenomenon to the correspondent of RIA Novosti said the head of group assistant Professor, Department of preventive medicine Department of medical research, Nagoya University Kenji Takeuchi.

Kenji Takeuchi for three years spent observing people over 65. The experiment involved 14 233. The task was to identify the correlation between the frequency of laughter and the ability to retain the power to self-serve themselves, without the need for outside help, and laughter and death. All subjects were divided into four groups depending on how often they laugh in a loud voice. The results showed that the risk of losing the ability to move and maintain itself, those who confessed that he almost laughs, increasing 1.4 times compared with those who laughs almost every day. Similar results were revealed for the first time in the world.

Israeli scientists told what foods increase cancer risk

Foods rich in antioxidants such as black tea, chocolate, nuts and berries, can increase the risk of developing certain types of cancer, found a group of researchers from the Centre for immunology and cancer research behalf of Lautenberg at the Hebrew University in Jerusalem, reported the press service of the institution.

"A thorough analysis revealed the culprit that causes cancer to spread rapidly in the large intestine: the intestinal flora that produces metabolites known as "antioxidants", which in high concentrations in foods such as black tea, chocolate, nuts and berries," - said in a press release released by the Hebrew University.

The next stage of compiling a complete encyclopedia of DNA elements.

The international ENCODE consortium, consisting of 500 scientists and biologists from many countries of the world announced the completion of the third phase of the global project on compilation of an encyclopedia of functional DNA elements. In 14 articles published in Nature, Nature Methods and Nature Communications, the authors summarize 17 years of experience.

The human genome contains about 20 thousand genes encoding proteins, which account for only about 1.5 percent of the DNA of the human genome.

Named a way to destroy coronavirus in 25 seconds

Scientists of the National laboratory of infectious diseases (NIEDL) Boston University during the joint with Signify research has identified an effective method of inactivation of coronavirus SARS-CoV-2.

In the study, researchers led by Dr. Anthony Griffiths conducted an experiment: they worked with the contaminated virus material with different doses of UV radiation. They then evaluated the rate of inactivation of the virus.

Cave Tavrida interested foreign scientists, said in RSP

Foreign scientists became interested in the Crimean cave "Tauris", but priority in its learning are given to domestic experts, said the head of the project "Cave Tauris", the President of the Russian Union of speleologists (CPR) Gennady Samokhin.

"We are already actively working with their colleagues from Austria by age Dating, to study the Mineralogy, isotopic composition. Apply the math that they were interested to come to the Crimea. We are ready to involve scientists from other countries, but in terms of partnership, not dominance. We have experts who can promote this project in the world of science. First we will start with, and then we'll continue our foreign colleagues," said Samokhin journalists in the Crimean press-center of MIA "Russia today".

Russian chemists found a method of producing a metal technetium

Russian scientists from RCTU named after D. I. Mendeleev together with colleagues from other institutes found a simple and cheap method for the synthesis of technetium — expensive and highly sought after metal that is practically not found in nature. The study is published in the journal of Electroanalytical Chemistry.

Technetium is a radioactive element that in large quantities contained in spent nuclear fuel. It is widely used in nuclear medicine as a contrast label for diagnostics of internal organs and tumors, but because of the complex process of obtaining it is very expensive.
