Molecular hydrogen (H2) makes up 99 percent of the cold, dense gas in galaxies. So mapping where stars are born basically means measuring H2, which lacks a strong characteristic signature at low temperatures. Astronomers ...

According to condensed matter physics predictions, at a high enough pressure, hydrogen should dissociate and transform into an atomic metal. However, the exact pressure range at which this occurs has not yet been ascertained, ...
Many potential pharmaceuticals end up failing during clinical trials, but thanks to new research from the University of Illinois, biological molecules once considered for cancer treatment are now being repurposed as organic ...

Helium and water are known to be abundant throughout the universe, particularly in giant planets such as Uranus and Neptune. Although helium is typically unreactive at common atmospheric conditions, past studies have found ...
Hydrogenases are enzymes that catalyze hydrogen activation. There are three types of hydrogenases in nature, all containing iron and some of them nickel. But in synthetic chemistry there is a whole host of metals that can ...
