1. Scientists of the Research Center "Kurchatov Institute" - State Research Institute of Genetics have developed a new method for producing nanoparticles with antibacterial, photocatalytic and other useful properties. In contrast to traditional approaches, microorganisms are used in the synthesis process. This ensures exceptional particle stability and preservation of their size within the nanoscale. The development was used to create nanocomposite polymer materials with a wide range of possible applications - from targeted drug delivery to the production of polymer products for various purposes.

2. Using the new method, researchers from the A.V. Topchiev Institute of Petrochemical Synthesis(INHS) of the Russian Academy of Sciences created new membranes based on silicone rubbers for the selective isolation of valuable organic compounds from contaminated water.

3. Russian researchers, along with colleagues from the UK and China, confirmed in an experiment that any classical fluid on a microscopic scale reacts to external mechanical influences like a solid. The data obtained during the work will help to create new nanodevices, nanostructures and metamaterials. They will make it possible to more accurately evaluate the physical parameters of liquids near the solidification temperature and the conditions for the synthesis of nanostructures.

4. Researchers at the A. N. Belozersky Research Institute of Chemical Biophysics and the Institute of Functional Genomics at Moscow State University, Skoltech, Hamburg and Illinois Universities analyzed how tetracenomycin acts on bacterial and human ribosomes. They showed that the tetracenomycin molecule inhibits the translation of proteins from both bacterial and human ribosomes.

5. Russian molecular biologists and mathematicians have found that some genes that are associated with the development and functioning of the brain of humans and other mammals contain many unusually long introns - inserts inside genes. In total, scientists found 153 DNA sections with such inserts.
