Poor protein utilization contributes to neurodegeneration

Neurodegeneration can occur more quickly if nerve cells lack retromer proteins, which are responsible for breaking down toxic tau protein. This conclusion was reached by scientists who observed genetically modified fruit flies that produced human tau protein in 39 neurons of the eye. Tau protein itself already caused the death of nerve cells, and the… Continue reading Poor protein utilization contributes to neurodegeneration

Chemists have found ideal conditions for the hydrogen borrowing reaction

Chemists from Russia studied the hydrogen borrowing reaction necessary for the formation of carbon-nitrogen bonds. They found that it often does not require a catalyst at all, and also developed recommendations for successfully carrying out the reaction in the laboratory. The study was published in the journal Journal of Catalysis. Organic compounds containing an NH… Continue reading Chemists have found ideal conditions for the hydrogen borrowing reaction

Short breaks during the day helped workers cope with fatigue

Small breaks during the workday help you feel more alert, less tired and more productive. This was found by Romanian psychologists who conducted a meta-analysis of 22 studies published over the past 30 years. Article published in the magazine PLoS ONE. In modern culture, work and personal space no longer have clear boundaries, and more… Continue reading Short breaks during the day helped workers cope with fatigue

Tea drinking linked to reduced risk of death from all causes

American researchers have found that drinking tea is associated with a decrease in mortality from all causes, and also found a relationship with a decrease in the likelihood of death from cardiovascular diseases, coronary heart disease and stroke. The results of a survey and medical examination of half a million Britons aged 40 to 69… Continue reading Tea drinking linked to reduced risk of death from all causes

Playing music in childhood has been linked to long-term improvements in cognitive abilities.

Playing a musical instrument in childhood and adolescence is associated with improved cognitive skills in later life, British researchers have found. The positive effect persisted even after adjusting for several factors, such as childhood environment. The study was published in Psychological Science. Developed cognitive skills can influence academic and professional achievements, as well as health.… Continue reading Playing music in childhood has been linked to long-term improvements in cognitive abilities.

Paleogeneticists read the genome of the “warrior with a griffin” from Nestor’s palace

Paleogeneticists have studied the origins of populations whose history is known from written sources. They discovered that the Mycenaeans arose from the mixing of Minoans and migrants whose origins were connected with the Eurasian steppe. However, the famous “warrior with a griffin,” whose rich burial was found in Pylos several years ago, did not have… Continue reading Paleogeneticists read the genome of the “warrior with a griffin” from Nestor’s palace

Pork protein corneas restored vision to 20 patients with keratoconus

Swedish scientists have developed corneal prostheses based on collagen from pig skin. In a pilot trial involving Indian and Iranian researchers, the prostheses helped restore vision to 20 patients with keratoconus. The report on the work was published in the journal Nature Biotechnology. The cornea is the anterior most convex part of the fibrous membrane… Continue reading Pork protein corneas restored vision to 20 patients with keratoconus

Belief in luck and predictions linked to the Human Development Index

Belief in the supernatural is widespread throughout the world, but belief in luck and fortune telling is strongest in some countries in South Asia and Eastern Europe, including Latvia, Russia, Indonesia and Singapore. And the least susceptible to such beliefs are the inhabitants of Protestant Europe. Australian scientists came to this conclusion after analyzing data… Continue reading Belief in luck and predictions linked to the Human Development Index

The Little Ice Age affected soils from the Tula Kremlin

Russian paleosoil scientists analyzed materials obtained during excavations in the Tula Kremlin. It turned out that the paleosols buried in the 15th century were formed under warm and dry conditions characteristic of the medieval climatic optimum. On the contrary, cultural layers of the 16th–18th centuries indicate climatic conditions characteristic of the Little Ice Age. It… Continue reading The Little Ice Age affected soils from the Tula Kremlin

Chromatin in a living cell exhibited the properties of a liquid

French biophysicists have studied the movement of chromatin – a complex of DNA and proteins – inside a living cell using magnetic nanoparticles. As a result, it turned out that chromatin moves inside the nucleus not as a gel formed from a cross-linked polymer network, but as a viscous liquid. The study was published in… Continue reading Chromatin in a living cell exhibited the properties of a liquid
