Lasers control ‘Goldilocks’ molecules
YALE (US) — Using lasers, physicists have been successful in cooling molecules down to temperatures near what’s known as absolute zero, about -460 degrees Fahrenheit. Continue…

‘Supercool’ atoms try to act like electrons
These three false-color images, from left, depict the density of cesium atoms in a superfluid (conducting) state, in a transition state and finally in an insulating state. The original sample consisted of a single-layer of cesium atoms that formed a sheet measuring 80 microns in diameter, barely visible to the naked eye. Green indicates the lowest density of atoms. Red indicates a high, constant density. Physicists call this a plateau, which a team of scientists have observed for the first time. (Courtesy: Nathan Gemelke and Cheng Chin/University of Chicago)
