Researchers from the Institute of Molecular Biology (IMB) and Johannes Gutenberg University in Mainz (JGU) have learned how to create membrane-free organelles in thin films.
Scientists still do not know the exact answer to the question of how exactly these animals manage to absorb wood in such quantities in the absence of digestion.
Rospotrebnadzor is preparing measures for the prevention of influenza and acute respiratory viral infections in 2021-2022. Australian scientists have found a way to increase the effectiveness of the immune system in oncological and chronic viral diseases. Russian scientists believe that infection with two different strains of SARS-Cov-2 is possible, but double infection does not lead to a more serious disease.
In both cases, the body produces antibodies, but how do they differ from each other?
The results of a phase 2 study of a new type 1 diabetes vaccine have shown that treatment is effective in a subset of patients with a specific set of genes. If the new treatment is confirmed by larger studies, it may be effective for half of patients suffering from diabetes.
First of all, it is necessary to understand in which region the water will be filtered. The initial quality of water differs depending on the geography of its source, for example, Moscow is characterized by an increased concentration of hardness salts, and Karelia is characterized by a modest mineral composition of water. Is it possible to purify any tap water to make it drinkable, as well as enrich it with the necessary nutrients? These and other questions were answered by Maria Kuleshova, an expert biochemist at Barrier.
It's no secret that the more we use antibiotics, the more likely it is that bacteria will develop resistance to them. A new antibacterial wound dressing is designed to solve this problem by using proteins instead of conventional antibiotics.
Copper is one of the most widely used metals, but its extraction from the rock and processing to a useful form requires a lot of energy and harsh chemical treatment. Researchers from the University of Houston have discovered bacteria that naturally convert toxic copper ions into metallic copper.
The mouse embryo was able to grow in an artificial uterus up to day 11 — half of the mouse's gestation period. Human skin cells were reprogrammed in such a way that an embryo was formed from them at the initial stage of development. Hereditary information is transmitted not only by DNA, but also by sperm proteins.
Obesity is the second most important risk factor for COVID—19 disease. Ultrasound stimulation of the liver helped the mice to get rid of excess weight. Adipose tissue cells on the abdomen block the process of fat breakdown during interval fasting, they can only be affected by a constant diet.
