Public Release: 5-Nov-2009 November 2009 story tips from the US Department of Energy's Oak Ridge National Laboratory
Fuel economy ratings for the new 2010 model year automobiles are posted at www.fueleconomy.gov, which ORNL maintains for the US Department of Energy and the US Environmental Protection Agency. A team led by ORNL's Nina Balke has moved closer to developing more rugged memory and logic devices. Heavy trucks are less heavy but just as safe and rugged because of steel rail frames. A new approach to crunching massive volumes of data uses neural networks like an artificial brain.
Public Release: 5-Nov-2009 Science Express Rapid supernova could be new class of exploding star
UC Berkeley post-doc Dovi Poznanski was looking through seven-year-old data when he chanced upon a very strange supernova that flashed and was gone in less than a month, when 3-4 months is typical. The unusually rapid supernova appears to match the predicted behavior of a thermonuclear explosion on a white dwarf that is drawing helium from its binary companion. This mechanism is quite different from the two standard types of supernovae.

Public Release: 2-Nov-2009 International Journal of Climatology Green is cool, but US land changes generally are not
Most land use changes occurring in the continental US result in raised regional surface temperatures, says a new study by scientists at the University of Maryland, Purdue University and the University of Colorado in Boulder.
The study in the Royal Meteorological Society's International Journal of Climatology found that almost any change that makes land cover less "green" contributes to warming. A perhaps less intuitive finding is that conversion of any land to agricultural use results in cooling, even land that was previously forested.

Public Release: 2-Nov-2009 Journal of Physical Chemistry C Rice U. lab leads hunt for new zeolites
In all the world, there are about 200 types of zeolite, a compound of silicon, aluminum and oxygen that gives civilization such things as laundry detergent, kitty litter and gasoline. But thanks to computations by Rice University professor Michael Deem and his colleagues, it appears there are -- or could be -- more types of zeolites than once thought.

Public Release: 2-Nov-2009 Earth and Planetary Science Letters 'Ultra-primitive' particles found in comet dust
Dust samples collected from the stratosphere have yielded an unexpectedly rich trove of relicts from the ancient cosmos, report scientists from the Carnegie Institution. The dust includes presolar grains and material from interstellar molecular clouds. This "ultra-primitive" material likely wafted into the atmosphere after the Earth passed through the trail of an Earth-crossing comet in 2003, giving scientists a rare opportunity to study cometary dust in the laboratory.

Public Release: 29-Oct-2009 Science Pinning down superconductivity to a single layer
Using precision techniques for making superconducting thin films layer-by-layer, physicists at the US Department of Energy's Brookhaven National Laboratory have identified a single layer responsible for one such material's ability to become superconducting, i.e., carry electrical current with no energy loss. The technique, described in the Oct. 30, 2009, issue of Science, could be used to engineer ultrathin films with "tunable" superconductivity for higher-efficiency electronic devices.

Public Release: 28-Oct-2009 Nature Gamma-ray photon race ends in dead heat; Einstein wins this round
A pair of gamma-ray photons -- one possessed of a million times the energy of the other -- arrived at virtually the same instant at NASA's orbiting Fermi Gamma-ray Space Telescope, after a 7.3 billion year race across the universe. Some proponents of alternatives to Einstein's theory of gravity would have predicted that the more energetic would have been much farther behind the less energetic one. They were wrong -- Einstein wins this round.

Public Release: 28-Oct-2009 Fermi telescope caps its first year with a glimpse of space-time
During its first year of operations, NASA's Fermi Gamma
Ray Space Telescope mapped the extreme sky with unprecedented
resolution and sensitivity. It captured more than one thousand
discrete sources of gamma rays -- the highest-energy form of light.
Capping these achievements was a measurement that provided rare
experimental evidence about the very structure of space and time,
unified as space-time in Einstein's theories.

Public Release: 27-Oct-2009 Scientists use world's fastest supercomputer to create the largest HIV evolutionary tree
In this study the evolutionary history of more than 10,000 sequences from more than 400 HIV-infected individuals was compared. The idea is to identify common features of the transmitted virus, and attempt to create a vaccine that enables recognition the original transmitted virus before the body's immune response causes the virus to react and mutate.
Public Release: 27-Oct-2009 Physical Review Magnetic mixing creates quite a stir
Sandia researchers have developed a process that can mix tiny volumes of liquid, even in complicated spaces.
Researchers currently use all types of processes to try and create mixing, with only "mixed" success. "In small devices," says Sandia materials scientist Jim Martin, "people have tried all kinds of pillars and mixing cells to initiate mixing, but these approaches don't work well." Researchers need simpler and more reliable ways to mix in tiny places such as micrometer-sized channels, Martin said.
Public Release: 27-Oct-2009 Stanford researchers awarded $6.27 million to study energy efficiency and human behavior

The US electricity grid is strained to its limit, and the nation's windiest and sunniest places are rarely near cities that generate high demand. Finding ways to string new power lines across several states is a challenge for even the most creative regulators and energy analysts determined to increase America's use of renewable energy.
The challenge of controlling climate change is a goal that, to many, appears to be at odds with the equally important goal of energy security. However, the idea that the two goals are somehow mutually exclusive is not one accepted by ORNL energy researcher David Greene. "We don't want to sacrifice one for the other," he says. "We want -- and we believe it possible -- to achieve environmental goals and energy security goals at the same time.
