The transition from simple chemistry to the complex biology of molecules that gave rise to life is a puzzle that scientists ...

Earlier theories had forecast an appreciable drop in the reaction probability at low temperatures, but we could not confirm this either in the experiment or in new calculations by our colleagues on ...

Scientists in Germany have recreated the universe's first molecule. The experiment mimics conditions after the Big Bang. It helps us understand how stars were formed. Researchers used a special ...

In a series of recent animal studies, a handful of deceptively simple molecules have done something that once sounded like science fiction: they have restored memory and reversed biological signs of ...

Rare and powerful compounds, known as keystone molecules, can build a web of invisible interactions among species. The biological world is awash in chemical signals. Ants lead their nest mates to food ...

As a graduate student at the University of California, Berkeley, Mark Levin started sketching out ideas for how to do something no chemist had ever managed before: swapping one of the carbon atoms in ...
