Whether it's used in chemical laboratories or the fuel tanks of advanced automobiles, hydrogen is mostly produced from natural gas and other fossil fuels. However, to isolate the tiny hydrogen molecules, engineers must first remove impurities, and the currently available methods can require substantial equipment or toxic chemicals.

Scientists at the Commerce Departments National Institute of Standards and Technology (NIST) have coaxed six atoms into spinning together in two opposite directions at the same time, a so-called Schrödinger "cat" state that obeys the unusual laws of quantum physics. The ambitious choreography could be useful in applications such as quantum computing and cryptography, as well as ultra-sensitive measurement techniques, all of which rely on exquisite control of natures smallest particles.

Since the creation of the first working laser - a ruby model made in 1960 - scientists have fashioned these light sources from substances ranging from neon to sapphire. Silicon, however, was not considered a candidate. Its structure would not allow for the proper line-up of electrons needed to get this semiconductor to emit light.
