Ohio State University researchers have captured the first-ever images of atoms moving within a molecule using a novel technique that turns one of the molecules own electrons into a kind of flash bulb.

Caltech's Konstantinos Giapis has shown how molecular oxygen may be produced on the surface of comets using lab experiments. He and his postdoctoral scholar Yunxi Yao fired high-speed water molecules ...

IBM scientists have been able to image the "anatomy" -- or chemical structure -- inside a molecule with unprecedented resolution, using a complex technique known as noncontact atomic force microscopy.

For the first time, astronomers have found molecular oxygen — the same gas humans need to breathe — in a galaxy outside the Milky Way. Oxygen is the third most common element in the cosmos, after ...
