Discovery could lead to new methods for environmental remediation and speeding up chemical reactions A glow coming from the glassy shell of microscopic marine algae called diatoms could someday help us detect chemicals and other substances in water samples. And the fact that this diatom can glow in response to an external substance could also help researchers develop a variety of new, diatom-inspired nanomaterials that could solve problems in sensing, catalysis and environmental...

Previous world record shattered during 6-experiment pulse Researchers at Los Alamos National Laboratory's biggest magnet facility today met the grand challenge of producing magnetic fields in excess of 100 tesla while conducting six different experiments. The hundred-tesla level is roughly equivalent to 2 million times Earth's magnetic field. "This is our moon shot, we've worked toward this for a decade and a half," said Chuck Mielke, director of the Pulsed Field Facility at Los Alamos....

Without fungi and microbes to break down dead trees and leaf litter in nature, the forest floor might look like a scene from TV's "Hoarders." Massive-scale genome sequencing projects supported by the U.S. Department of Energy (DOE) and being carried out at the DOE Joint Genome Institute (JGI) highlight the importance of learning how the cellulose, hemicellulose and lignin that serve as a plant's infrastructure can be broken down by these forest organisms to extract needed nutrients. Among...

Daya Bay Scientists Observe Previously Unseen Neutrino Transformation
2012-03-09 05:38:53

An international team of physicists collaborating on a neutrino experiment that began six years ago released their first results on Thursday, and they report that for the first time they have witnessed an elusive process in which one type of these subatomic particles transforms into another. The findings originate from the Daya Bay Reactor Neutrino Experiment, the first equal collaboration between scientists from the US and China which began in 2006 and has since gained financial,...

Discovery paves the way for new synthesis of antibiotics Researchers working at the U.S. Department of Energy's (DOE) SLAC National Accelerator Laboratory have used powerful X-rays to help decipher how certain natural antibiotics defy a longstanding set of chemical rules — a mechanism that has baffled organic chemists for decades. Their result, reported today in Nature, details how five carbon atoms and one oxygen atom in the structure of lasalocid, a natural antibiotic produced...

Word of the Day
  • The hard inner (usually woody) layer of the pericarp of some fruits (as peaches or plums or cherries or olives) that contains the seed.
This word comes from the Greek 'endon,' in, within, plus the Greek 'kardia,' heart.
