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...

Scientists talked about new ways to combat neurodegenerative diseases
2023-09-29 17:37 Scientists analyzed studies on neurodegenerative diseases such as Alzheimer's, Huntington's and dementia with Levi's corpuscles, and found out what an important role three proteins of the PIDDOSOME complex play in them, triggering the process of programmed cell death. Thus, mutations in two of them — PIDD1 and RAIDD — lead to abnormalities in brain development, and an excess of the third — caspa...

Long-moustached short-moustaches: a transitional form between mosquitoes and flies was found in the Triassic
2023-09-15 11:38 The order Diptera includes, as the name implies, insects with only one pair of wings. The body structure of diptera can be reduced to two main types: mosquitoes with multi-lobed antennae and flies with three-lobed antennae. This difference was noticed a long time ago: diptera were divided into long-whiskered Nematocera and short-whiskered Brachycera in the first half of the XIX century. But as often happens...
