Scientists develop a room temperature maser to amplify weak signals

The spacecraft Voyager 2 has travelled a barely imaginable 17 billion kilometers from Earth and continues to send signals to the ground station. This is made possible by the maser technology, which works on similar principles to the laser and is able to amplify weak microwave signals almost noise-free.

Breakthrough in photonic biosensors could lead to super-accurate diagnostic and detectors

University Professor of Applied Physics Stephen Arnold and his team at the New York University Tandon School of Engineering have made a discovery that could lead to Star Trek-like biosensor devices capable of flagging the barest presence in blood of a specific virus or antibody, or protein marker for a specific cancer; or sniffing out airborne chemical warfare agents while they are still far below toxic levels. The discovery follows years of groundbreaking work by Arnold, who in 1995 discovered that an optical fiber could excite what he termed Whispering Gallery Mode in silicon micro-beads less than one-third the diameter of a human hair.
