Size Matters When Nanocrystals Go Through Phases
2013-08-26 15:35:09

Lawrence Berkeley National Laboratory Berkeley Lab Researchers at the Molecular Foundry Reveal Fundamental Size-Dependence of Metal Nanocrystals Undergoing Phase Transitions Understanding what happens to a material as it undergoes phase transformations – changes from a solid to a liquid to a gas or a plasma – is of fundamental scientific interest and critical for optimizing commercial applications. For metal nanocrystals, assumptions about the size-dependence of phase...

Research Could Help Scientists Predict How Carbon Is Stored Underground
2013-08-23 05:49:36

Lawrence Berkeley National Laboratory Computer simulations conducted at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) could help scientists make sense of a recently observed and puzzling wrinkle in one of nature’s most important chemical processes. It turns out that calcium carbonate—the ubiquitous compound that is a major component of seashells, limestone, concrete, antacids and myriad other naturally and industrially produced substances—may...

Researchers Discover A Tiny Twist In Bilayer Graphene That May Solve A Mystery
2013-08-12 16:36:44

Lawrence Berkeley National Laboratory Researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) have discovered a unique new twist to the story of graphene, sheets of pure carbon just one atom thick, and in the process appear to have solved a mystery that has held back device development. Electrons can race through graphene at nearly the speed of light – 100 times faster than they move through silicon. In addition to being superthin...

FTIR Spectro-microtomography Unveiled By Researchers
2013-08-06 07:04:48

Lawrence Berkeley National Laboratory An iconic moment in the history of Hollywood movie magic was born in the 1939 film The Wizard of Oz when Judy Garland as Dorothy Gale stepped out of the black and white world of Kansas into the rainbow colored world of Oz. An iconic moment in the history of infrared imaging may have been born with the announcement of the first technique to offer full color IR tomography. A collaboration between researchers at the U.S. Department of Energy's Lawrence...

This Image May Lead To Better Antibiotics
2013-06-28 13:45:14

Lawrence Berkeley National Laboratory Berkeley Lab scientists create atomic-scale structure of ribosome attached to a molecule that controls its motion This may look like a tangle of squiggly lines, but you're actually looking at a molecular machine called a ribosome. Its job is to translate DNA sequences into proteins, the workhorse compounds that sustain you and all living things. The image is also a milestone. It's the first time the atom-by-atom structure of the ribosome has been...

Researchers Increase NMR/MRI Sensitivity Through Hyperpolarization Of Nuclei In Diamond
2013-06-06 15:09:01

Lawrence Berkeley National Laboratory Today´s nuclear magnetic resonance (NMR) and Magnetic Resonance Imaging (MRI) technologies, like quantum information processing and nuclear spintronic technologies, are based on an intrinsic quantum property of electrons and atomic nuclei called “spin.” Electrons and nuclei can act like tiny bar magnets with a spin that is assigned a directional state of either “up” or “down.” NMR/MRI signals depend upon a...

How And Where Breast Tumor Cells Become Dormant And What Causes Them To Become Metastatic
2013-06-03 19:49:37

Lawrence Berkeley National Laboratory The long-standing mystery behind dormant disseminated breast tumor cells and what activates them after years and even decades of latency may have been solved. Researchers with the U.S. Department of Energy (DOE)´s Lawrence Berkeley National Laboratory (Berkeley Lab) have identified the microenvironment surrounding microvasculature — the small blood vessels that transport blood within tissues — as a niche where dormant cancer cells...

Big Molecule Models Captured In A Flash
2013-05-28 11:02:32

Lawrence Berkeley National Laboratory To learn how biological molecules like proteins function, scientists must first understand their structures. Almost as important is understanding how the structures change, as molecules in the native state do their jobs. Existing methods for solving structure largely depend on crystallized molecules, and the shapes of more than 80,000 proteins in a static state have been solved this way. The majority of the two million proteins in the human body...

Researchers Extend Electron Spin In Diamond For Incredibly Tiny Magnetic Detectors
2013-05-10 10:18:01

Lawrence Berkeley National Laboratory From brain to heart to stomach, the bodies of humans and animals generate weak magnetic fields that a supersensitive detector could use to pinpoint illnesses, trace drugs — and maybe even read minds. Sensors no bigger than a thumbnail could map gas deposits underground, analyze chemicals, and pinpoint explosives that hide from other probes. Now scientists at the U.S. Department of Energy´s Lawrence Berkeley National Laboratory (Berkeley...

Researchers Develop Enzyme-free Ionic Liquid Pre-treatment For Cellulosic Biomass
2013-05-09 11:43:26

Lawrence Berkeley National Laboratory Advanced biofuels — liquid fuels synthesized from the sugars in cellulosic biomass — offer a clean, green and renewable alternative to gasoline, diesel and jet fuels. Bringing the costs of producing these advanced biofuels down to competitive levels with petrofuels, however, is a major challenge. Researchers at the U.S. Department of Energy (DOE)´s Joint BioEnergy Institute (JBEI), a bioenergy research center led by Berkeley Lab, have...


Word of the Day
grass-comber
  • A landsman who is making his first voyage at sea; a novice who enters naval service from rural life.
According to the OED, a grass-comber is also 'a sailor's term for one who has been a farm-labourer.'
