Scientists uncover a multibillion-year epic written into the chemistry of life
The origin of life on Earth has long been a mystery that has eluded scientists. A key question is how much of the history of life on Earth is lost to time. It is quite common for a single species to "phase out" using a biochemical reaction, and if th.....»»
Novel design approach achieves nonlinear photochromism using easy-to-synthesize rhodamine spirolactam derivatives
Photochromic compounds, which change their color when exposed to light, have been widely used as photo switches to control different properties of materials. Nonlinear photochromic compounds, characterized by a nonlinear response to the intensity of.....»»
Researchers reveal a new mechanism of hyaluronic acid with a specific molecular weight to improve host inflammation
Previous studies on the function of glycosaminoglycans have primarily focused on improving host physiological indices. However, little attention has been paid to the material basis and mechanism of their mediated improvement of host health by gut mic.....»»
