OAK RIDGE, Tenn. -- Atomic-level defects in graphene could be a path forward to smaller and faster electronic devices, according to a study led by researchers at the Department of Energy's Oak Ridge National Laboratory.

There are an estimated 150 million works of art in the market today – in museums, public spaces and in the holdings of private collectors. Not only because of their material value, but also because of their intangible value they deserve to be handled carefully. However, neither artists nor museums or collectors want to protect artwork from detrimental influences by keeping it in a climate-controlled safe. Art needs the public.
Researchers at Rice University are using carbon nanotubes as the critical component of a robust terahertz polarizer that could accelerate the development of new security and communication devices, sensors and non-invasive medical imaging systems as well as fundamental studies of low-dimensional condensed matter systems.
Two decades after the United Nations established the Framework Convention on Climate Change in order to prevent dangerous anthropogenic interference with the climate system, the Arctic shows the first signs of a dangerous climate change. A team of researchers led by CSIC assures so in an article published on the latest number of the Nature Climate Change magazine.

BEER-SHEVA, Israel -- An international team of researchers including Dr. Bertrand Boeken of the Jacob Blaustein Institutes for Desert Research at Ben-Gurion University of the Negev suggest in a new study that plant biodiversity preservation is crucial to buffer negative effects of climate change and desertification in drylands.
Using computer simulations, a RUB researcher has shown that the oxygen molecule (O2) is stable up to pressures of 1.9 terapascal, which is about nineteen million times higher than atmosphere pressure. Above that, it polymerizes, i.e. builds larger molecules or structures. "This is very surprising" says Dr. Jian Sun from the Department of Theoretical Chemistry.
A study published in Nature Climate Change today finds that tropical vegetation contains 21 percent more carbon than previous studies had suggested. Using a combination of remote sensing and field data, scientists from Woods Hole Research Center (WHRC), Boston University, and the University of Maryland were able to produce the first "wall-to-wall" map (with a spatial resolution of 500 m x 500 m) of carbon storage of forests, shrublands, and savannas in the tropics of Africa, Asia, and South America.

2010 Haiti quake possible start of new cycle of seismic activity, according to new study
The January 2010 quake that destroyed much of Port-au-Prince may have marked the start of a new cycle of active seismicity, putting Haiti and the Dominican Republic at high risk of future devastating earthquakes.
Graphene is one of the wonders of the science world, with the potential to create foldaway mobile phones, wallpaper-thin lighting panels and the next generation of aircraft. The new finding at the University of Manchester gives graphene's potential a most surprising dimension – graphene can also be used for distilling alcohol.
Lab scientists and international collaborators have created the shortest, purest X-ray laser pulses ever achieved, fulfilling a 45-year-old prediction and ultimately opening the door to new medicines, devices and materials.
The researchers, reporting today (Jan. 26) in Nature, aimed radiation from Linac Coherent Light Source (LCLS), located at the Stanford Linear Accelerator Center (SLAC), at a cell containing neon gas, setting off an avalanche of X-ray emissions to create a new "atomic X-ray laser."
RIVERSIDE, Calif. – Does antimatter behave differently in gravity than matter? Physicists at the University of California, Riverside have set out to determine the answer. Should they find it, it could explain why the universe seems to have no antimatter and why it is expanding at an ever increasing rate.

The tsunami that followed on the heels of the March 11, 2011, earthquake in Japan produced as much as 25 million tons of debris. Much of this debris was swept into the ocean. What stayed afloat drifted apart under the influence of winds and currents, most of it eastward. Predicted to reach the West Coast of the United States and Hawaii within the coming years, the debris' composition and how much is still floating on the surface are largely unknown. One thing is certain: the debris is hazardous to navigation, marine life, and when washed ashore, to coastlines.
A new catalytic process discovered at Cardiff University could unleash a range of useful new by-products from diesel fuel production.
More sustainable production of sulphur-free diesel from natural gas and biomass is increasing. However the by-products, hydrocarbons like decane and other low value alkanes have little practical use.
Now a discovery at the University's Cardiff Catalysis Institute has found a potential route for upgrading these by-products into more useful chemicals.
