New metrological technique uses stress for nanotomography
2022-07-15 12:58 Researchers from Skoltech and their colleagues in Russia and Spain have reported a proof-of-concept demonstration of a new radiation-safe method for mapping the internal structure and stress distribution in samples of materials at the nanoscale, with a resolution about 100 times higher than that of the currently available techniques: X-ray and neutron tomography. The team believes that its 3D stress nanotom...
MSU chemists have found a more effective carrier for antitumor drugs
2022-07-08 16:23 Employees of the Departments of Radiochemistry and High-Molecular Compounds of the Faculty of Chemistry of Moscow State University with colleagues from the V.N. Orekhovich Research Institute of Biomedical Chemistry investigated the antitumor activity of complexes of biocompatible microgel polysaccharide carboxymethylcellulose crosslinked with copper radionuclides. The cytotoxicity of such complexes in relat...
Botanists have described the first predatory plant with underground hunting pitchers
2022-07-01 12:41 Botanists have described the first predatory plant with underground hunting pitchers. The species, called nepenthes bashful, grows only in the north of Borneo and hunts mainly ants. Probably, moving the pitchers underground allows this plant not to compete with other nepenthes or survive droughts.Nepenthes (Nepenthes) are one of the most famous hish plants. They are easily recognized by their characteristic...
Most schools in the world are poorly equipped to provide a healthy and inclusive learning environment
2022-06-24 10:22 The number of schools without basic water, sanitation and hygiene services is constantly decreasing, but there is still a deep inequality in this indicator between countries and even within them. Schoolchildren in the least developed countries suffer the most. This is stated in a joint report published on Thursday by UNICEF and the World Health Organization (WHO). "A lot of children attend schools where th...
The molecule decomposed to form phosphorus mononitride
2022-06-17 16:17 Chemists from the USA and Germany synthesized a compound capable of decomposing to form phosphorus mononitride PN. The resulting mononitride quickly turned into a polymer, but chemists managed to intercept it with an iron complex. As a result, a complex compound was formed with phosphorus mononitride as a ligand. The molecules of phosphorus mononitride PN are similar in electronic structure to nitrogen mol...
Scientists have proposed a new way to fight cancer
2022-06-10 10:31 The collaboration of researchers with the participation of specialists from the HSE International Bioinformatics Laboratory has presented a new way to combat intractable melanoma. Scientists have discovered that one of the forms of the DNA molecule, getting into cancer cells, can cause an immune response similar to the body's reaction to the virus. As a result, the cells that support the growth of the t...
Rescue us from our environmental ‘mess’, UN chief urges Stockholm summit
2022-06-03 08:00 Global wellbeing is at risk – and it’s in large part because we haven’t kept our promises on the environment – UN Secretary-General António Guterres said on Thursday.Although there have been successes in protecting the planet since 1972, including rescuing the ozone layer, Mr. Guterres warned that “Earth’s natural systems cannot keep up with our demands”.Triple planetary crisis“Lead us out of this mess”, he...
