The scientists of far Eastern Federal University (FEFU), in collaboration with colleagues from the far East branch of RAS has developed a sorbent, which can be used to purify water from radioactive elements, and also to process liquid radioactive waste, the press service of the University.
The sorbent was synthesized on the basis of the composite powder of "tungsten bronze" (Na2WO4).
Paleontologists from St. Petersburg created the first detailed virtual 3D model of the brain and blood vessels of the head ankylosaur — herbivorous dinosaur, fragments of skull which was found in Uzbekistan. The study is published in the journal Biological Communications.
Ankylosaurs appeared in the middle Jurassic about 160 million years ago and existed until the end of the age of dinosaurs, which ended 66 million years ago. In the course of the study, the authors examined the fragments of fossil skulls of ankylosaur Bissektipelta archibaldi discovered during a series of international expeditions in the late 1990s and early 2000-ies in the area Djarkuduk in the Central Kyzylkum desert in Uzbekistan.
Russian scientists first read the genome of microbes in butter of different brands and found a number of opportunistic species, including dangerous for children. The study is published in the journal Foods.
Dairy products — the excellent environment for the growth of many dangerous bacteria, e.g. Salmonella. In Russia, the product quality according to established Standards, but even at observance of all norms of production, to ensure the absence of microbial contamination is impossible, as it often happens that the microorganisms can be detected only with the involvement of the latest scientific methods.
Animals that have experienced a vaccine against coronavirus, responded well to it, has told on air "Russia 1" the Director of the center "Vector" Rinat Maksyutov.
"In the framework of laboratory tests of the lower primates have also been infected with the novel coronavirus. The results were, they model the infection as a person. There are a significant number of asymptomatic cases, i.e. when the virus is we can only control warusawithana in a smear using PCR method", — he said.
The General Director of the scientific center "Vector" Rinat Maksyutov said that to begin clinical trials of a vaccine against COVID-19 will be held in late June - early July and be completed in mid-September.
He noted that additional speed on a vaccine is not required because it is impossible to forget about the basic principles of vaccination - not to harm and not to stick a useless product.
