Black hole seeds missing in cosmic garden
In the vast garden of the universe, the heaviest black holes grew from seeds. Nourished by the gas and dust they consumed, or by merging with other dense objects, these seeds grew in size and heft to form the centers of galaxies, ...

Nanocatalyst makes heavy work of formic acid
Hydrogen occurs in nature as H2 molecules; however when deuterium isotopes—so called "heavy hydrogen"—are introduced, the result can be deuterium hydride (HD) or deuterium gas (D2). These compounds are useful starting ...
