Ulcer Bug's Achilles' Heel Found Through Experiment
2012-12-10 21:25:38

SLAC National Accelerator Laboratory X-rays Pinpoint Drug Target for Bacteria that Affect Hundreds of Millions Worldwide Experiments at the U.S. Department of Energy's (DOE) SLAC National Accelerator Laboratory have revealed a potential new way to attack common stomach bacteria that cause ulcers and significantly increase the odds of developing stomach cancer. The breakthrough, made using powerful X-rays from SLAC's Stanford Synchrotron Radiation Lightsource (SSRL), was the...

SLAC National Accelerator Laboratory Time's quantum arrow has a preferred direction, new analysis shows Time marches relentlessly forward for you and me; watch a movie in reverse, and you´ll quickly see something is amiss. But from the point of view of a single, isolated particle, the passage of time looks the same in either direction. For instance, a movie of two particles scattering off of each other would look just as sensible in reverse — a concept known as time reversal...

Supercharged Atoms Force Rethink On Existing Theories
2012-11-12 12:21:38

Brett Smith for redOrbit.com - Your Universe Online An international team of researchers has created ionized xenon atoms so positively charged that scientists involved in the study are now saying the existing theories need to be reexamined. Using the world´s most powerful laser, the Linac Coherent Light Source (LCLS) at the U.S. Department of Energy's (DOE) SLAC National Accelerator Laboratory at Stanford University, the physicists were able to kick out up to 36 electrons from a...

Prestigious Panofsky Prize Won By Stanford's Blas Cabrera For Dark Matter Work

Extreme Plasma Theories Are Being Put To The Test
2012-08-07 13:20:41

The first controlled studies of extremely hot, dense matter have overthrown the widely accepted 50-year old model used to explain how ions influence each other's behavior in a dense plasma. The results should benefit a wide range of fields, from research aimed at tapping nuclear fusion as an energy source to understanding the inner workings of stars. The study also demonstrates the unique capabilities of the Linac Coherent Light Source (LCLS) X-ray laser at the U.S. Department of Energy...

BELLA Laser Achieves One Pulse Per Second For World Record Power
2012-07-27 12:07:54

BELLA Laser Achieves One Pulse Per Second For World Record Power As Berkeley Lab´s laser plasma accelerator project BELLA nears completion, its drive laser has delivered one petawatt — a quadrillion watts — of peak power once each second, a world record for laser performance On the night of July 20, 2012, the laser system of the Berkeley Lab Laser Accelerator (BELLA), which is nearing completion at the U.S. Department of Energy´s Lawrence Berkeley National...

X-ray Imaging To Observe Running Batteries In Action
2012-07-18 09:56:44

Most electric cars, from the Tesla Model S to the Nissan Leaf, run on rechargeable lithium-ion batteries — a pricey technology that accounts for more than half of the vehicle's total cost. One promising alternative is the lithium-sulfur battery, which can theoretically store five times more energy at a much lower cost. But lithium-sulfur technology has a major drawback: After a few dozen cycles of charging and discharging, the battery stops working. "The cycle life of...

Soot Particles Measured In Flight
2012-06-27 12:53:57

"For the first time we can actually see the structure of individual aerosol particles floating in air, their 'native habitat'," said DESY scientist Henry Chapman from the Center for Free-Electron Laser Science (CFEL) in Hamburg. "This will have important implications for various fields from climate modelling to human health." CFEL is a joint venture of Deutsches Elektronen-Synchrotron DESY, the German Max Planck Society and the University of Hamburg. Aerosol particles like soot play...

Aerosol Structures Exposed By X-ray vision
2012-06-27 12:48:29

Laser probes microscopic components of air pollution Researchers at the U.S. Department of Energy's (DOE) SLAC National Accelerator Laboratory have captured the most detailed images to date of airborne soot particles, a key contributor to global warming and a health hazard. The discovery reveals the particles' surprisingly complex nanostructures and could ultimately aid the understanding of atmospheric processes important to climate change, as well as the design of cleaner combustion...

For the first time, scientists have seen an X-ray-irradiated mineral go to two different states of matter in about 40 femtoseconds (a femtosecond is one quadrillionth of a second). Using the Linac Coherent Light Source (LCLS) X-ray Free-Electron Laser (XFEL) at SLAC National Accelerator Laboratory at Stanford, Stefan Hau-Riege of Lawrence Livermore National Laboratory and colleagues heated graphite to induce a transition from solid to liquid and to warm-dense plasma. Ultrafast phase...


Word of the Day
conjunto
  • A style of popular dance music originating along the border between Texas and Mexico, characterized by the use of accordion, drums, and 12-string bass guitar and traditionally based on polka, waltz, and bolero rhythms.
The word 'conjunto' comes through Spanish, from Latin coniūnctus, past participle of coniungere, to join together; see conjoin
