New ocean observations improve understanding of motion
Oceanographers commonly calculate large scale surface ocean circulation from satellite sea level information using a concept called 'geostrophy', which describes the relationship between oceanic surface flows and sea level gradient. Conversely, researchers rely on data from in-water current meters to measure smaller scale motion. New research led by the University of Hawai'i has determined from observational data the length scale at which using sea level height no longer offers a reliable calculation of circulation.

Researchers use sound to slow down, speed up, and block light
Researchers from the University of Illinois at Urbana-Champaign have experimentally demonstrated, for the first time, the phenomenon of Brillouin Scattering Induced Transparency (BSIT), which can be used to slow down, speed up, and block light in an optical waveguide. The BSIT phenomenon permits light to travel in the forward direction while light traveling in the backward direction is strongly absorbed. This non-reciprocal behavior is essential for building isolators and circulators. (2015-01-27)
