The results of the study, supported by a grant from the Presidential Program of ...

Air Pollution Hides Increases in Rainfall

2024-03-01 20:44 We know that greenhouse gas emissions like carbon dioxide should increase rainfall. The emissions heat the atmosphere, causing a one-two punch: warmer oceans make it easier for water to evaporate, and warmer air can hold more water vapor, meaning more moisture is available to fall as rain. But for much of the 20th century, that increase in precipitation didn’t clearly show up in the data.A new study led by ...

Nanozymes will help diagnose hormones and blood diseases

2024-01-05 20:23 Scientists have developed special nanoparticles — nanosimes. They are used in molecular biological analyses as a label - they can be used to tint colorless substrates (antibodies, antigens, hormones) during diagnosis. Unlike natural analogues, nanosimes have high signal stability and are also relatively cheap. Scientists note that the use of nanosimes in the future will help reduce the prices of various med...

Upper Paleolithic people prepared paint using boiling

2023-12-29 19:38 Archaeologists have determined that the ancient people who lived in the Mezmai cave in the North Caucasus used multicomponent paints 31 thousand years ago. They consisted of bitumen and white and red clay with a protein binder based on gelatin glue. To get such glue, people boiled the skin or bones of animals. To date, this is the oldest evidence of boiling in history. The results of the study, supported by...
