Coincidence? I think so: researchers use phylogenetics to untangle convergent adaptation in birds
2021-06-24 19:18
Researchers from Skoltech and their colleagues have shown that adaptation to similar environments hardly involves similar genomic positions when species are distantly related. The team investigated recurrent adaptations of wildlife birds’ mitochondria to high altitude, migration, diving, wintering, and flight. Repeatable substitutions are rather a coincidence than adaptation, which confirms the scientific o...
Syria floods: Humanitarians working ‘round the clock’ to provide urgent relief
2021-06-23 12:38
Humanitarian staff have been working “round the clock” to reopen access roads and provide emergency relief from the disastrous impact that recent floods have unleased on displaced people living in camps in northwest Syria, the UN’s deputy humanitarian coordinator there said on Friday.
Providing shelter, food, clean water and other relief supplies is “a massive undertaking…[that] will continue for months”,...
In Europe, one in three children between the ages of 2 and 17 experiences some form of violence
2021-06-22 18:04
Millions of young Europeans are subjected to beatings and psychological pressure, including in their own homes, where they should feel safe. In Europe, one in three children experiences some form of violence. This is stated in a new report by the WHO European Office.
In the last year alone, 12 per cent of children between the ages of 2 and 17 experienced violence in the European Region. Many cases of maltr...
Scientists have synthesized a unique molecule of verdazyl-nitroxyl triradical
2021-06-21 12:10
Scientists of Tomsk Polytechnic University together with colleagues synthesized a unique molecule of verdazyl-nitroxyl triradical. Only a few research groups in the world were able to obtain molecules with similar properties. The molecule is stable, can withstand high temperatures, and has promising magnetic properties. This is a continuation of the work of scientists in the search for promising organic mag...
Scientists have found out what makes a person sneeze
2021-06-20 12:40
American scientists have identified the neural mechanism of sneezing. It turned out that this process is responsible for areas of the brain that are not associated with breathing. Scientists first identified the area in the central nervous system that causes sneezing more than twenty years ago, but until now little was known about how the sneezing reflex works at the cellular and molecular level.

The toothy "hummingbird dinosaur" turned out to be an ancient lizard
2021-06-19 12:27
Paleontologists have put an end to the debate about a strange animal found in Cretaceous amber: it is not a primitive bird that still retained its teeth in its beak, but an ancient scaly lizard.Last year, Chinese paleontologists presented an amazing find — a fragment of ancient amber, which perfectly preserved the remains of one of the most miniature dinosaurs in history. The sample was dated to be about 99...
MSU biologists understand the spatial organization of protein biosynthesis in cells
2021-06-18 11:19
The staff of the MSU Research and Educational School "Molecular Technologies of Living Systems and Synthetic Biology" collected data on localized protein biosynthesis in eukaryotic cells. The study will help to understand, among other things, the formation of special intracellular structures — “virus factories”.
The researchers of the Belozersky Research Institute of the Moscow State University have publis...
