[ad_1] Within a single cell, thousands of molecules, such as proteins, ions and other signaling molecules, work together to carry out all types of functions: to absorb nutrients, storing memories and differentiate into specific tissues, among many others. Deciphering these molecules and all their interactions is a monumental task. Over …

[ad_1] Cells are constantly moving throughout our body, performing a myriad of operations critical to tissue development, immune responses, and general well-being. This commotion is driven by chemical signals long studied by scientists interested in cell migration. To better understand this phenomenon, a team of biologists and physicists, led by …

[ad_1] Scientists at Tohoku University have found that human editing enzymes are likely behind a type of mutation in the COVID-19 virus that stimulates the release of pro-inflammatory molecules called cytokines by the body’s immune cells. The discovery, published in Scientific Reports, is important for understanding how the virus is …
