NIST Researchers measure and modulate trapped light.
2015-12-28 14:31:10| Industrial Newsroom - All News for Today
Researchers working at NIST have developed novel way to non-invasively measure and map how and where trapped light vibrates within microscale optical resonators. New technique not only makes for more accurate measurements but also allows scientists to fine-tune trapped light’s frequency by subtly altering shape of resonator itself. Visualizing vibration patterns will help scientists to perfect ultrasensitive optical sensors for detecting biomolecules and even single atoms.

MIT researchers have figured out how to make solar cells with old car batteries
2015-12-24 13:31:00| Climate Ark Climate Change & Global Warming Newsfeed
BGR: Heres a clever technological breakthrough that could help the environment in two ways. MIT announced this week that some of its researchers have figured out a way to make solar cells using parts from discarded car batteries that would otherwise have simply gone to waste. Essentially, the researchers have figured out how to extract lead from old car batteries and use it as a component in solar cells that they say are just as efficient as solar cells produced with high-purity, commercially available...
Salty sea spray affects lifetimes of clouds, researchers find
2015-12-23 18:02:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: All over the planet, every day, oceans send plumes of sea spray into the atmosphere. Beyond the poetry of crashing ocean waves, this salt- and carbon-rich spray has a dramatic effect on the formation and duration of clouds. Yes, clouds, which cover 60 percent of Earth's surface at any given time. In a new study in Proceedings of the National Academy of Sciences, online Dec. 21, Colorado State University's Paul DeMott, a senior research scientist in the Department of Atmospheric Science, says sea...

Researchers say less Arctic sea ice means more precipitation
2015-12-22 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Associated Press: A research paper published Monday by U.S. and Canadian scientists says less sea ice in the Arctic has meant more precipitation is falling. Lead author Ben Kopec, of Dartmouth College, says researchers looked at 20 years of precipitation data at sites in the Canadian Arctic and the Greenland Sea. They measured isotope compositions to determine whether moisture originated in the Arctic or from lower latitudes. They found that as sea ice diminished, more precipitation fell and more came from Arctic...
