A graduate student of the ITMO Faculty of Information Technology and Programming has created a new method for automatic recognition of brain tumors from MRI images. It will allow you to better interpret the predictions of the neural network to determine where it is not sure.
Scientists of the Skolkovo Institute of Science and Technology and Saratov State University named after N. G. Chernyshevsky have developed a new, cost-effective method for visualizing blood flow in the vessels of the brain. The accuracy of the method is so high that it allows reconstructing the vascular map by the movement of individual red blood cells, and without the use of toxic dyes and expensive genetic engineering.
Non-coding RNA in the cell enters some important organelles, regulates protein synthesis, accelerates individual reactions and participates in other biologically important processes. Often, the functioning of non-coding RNAs is ensured by stable interactions of nucleotides of one or more RNA molecules. A bioinformatician from MIPT and the Institute of Mathematical Problems of Biology of the Russian Academy of Sciences described the known structures of non-coding RNAs associated with adenine.
Krasnoyarsk scientists have obtained new promising thin films made of oxygen, copper and titanium nitride. Their electrical resistance is a thousand times less than that of ordinary titanium nitride. Based on the obtained material, physicists have discovered new properties of copper that allow it to accumulate on the surface of films and make phase transitions. The results obtained can become a technological breakthrough in the development of resistors and transistors of a new generation.
The developers of the Russian EpiVacCorona vaccine called their drug safe and not causing any special problems. Except, perhaps, one.
Experts say that after vaccination with the Russian drug Sputnik V, there are no problems with blood thickening and thrombosis. Why?
Observations on the telescopes of the Caucasus Mountain Observatory of Moscow State University allowed MSU scientists to discover the change in the orbital period and the ellipticity of the orbit, as well as to clarify the mass of the invisible black hole in the SS433 system.
The Minister of Health of the Russian Federation Mikhail Murashko told what vaccines can be revaccinated against coronavirus infection.
An international group of scientists has developed a new composite radio-absorbing material based on a polymer matrix with a filler of hexaferrite and nanographite, which effectively absorbs electromagnetic radiation in the microwave range and can be used for technology to reduce visibility. Studies have shown that the new composite is capable of absorbing up to 99.9% of electromagnetic radiation, which opens up prospects for reducing its visibility in the field of radar frequencies.
Thanks to the joint work of several X-ray observatories, it was possible to detect an accreting X-ray pulsar with the weakest magnetic field known to date.
