- The first non-trivial atom circuit: Progress towards an atom SQUID
"Researchers from the National Institute of Standards and Technology and the University of Maryland have created the first nontrivial "atom circuit," a donut-shaped loop of ultracold gas atoms circulating in a current analogous to a ring of electrons in a superconducting wire. The circuit is "nontrivial" because it includes a circuit element—an adjustable barrier that controls the flow of atom current to specific allowed values."

"…they connected a powerful electrical amplifier to a wand-like probe and used the device to shoot beams of electricity at an open flame more than a foot high. Almost instantly, the flame was snuffed out. Much to their fascination, it worked time and again."

"The search for alien life usually focuses on planets around other stars. But a lesser-known possibility is that life has sprung up on planets that somehow were ejected from their original solar systems and became free-floating in the universe, as well as on small bodies called sub-brown dwarfs, which are stars so small and dim they are not really stars at all, but function more like planets."
