Public Release: 2-Jul-2009 Ecological Applications Pacific Northwest forests could store more carbon, help address greenhouse issues
The forests of the Pacific Northwest hold significant potential to increase carbon storage and help mitigate greenhouse gas emissions in coming years, a recent study concludes, if they are managed primarily for that purpose through timber harvest reductions and increased rotation ages.

Public Release: 2-Jul-2009 Science Pinpointing origin of gamma rays from a supermassive black hole
An international collaboration of 390 scientists reports the discovery of an outburst of very-high-energy gamma radiation from the giant radio galaxy Messier 87, accompanied by a strong rise of the radio flux measured from the direct vicinity of its super-massive black hole. The combined results give first experimental evidence that particles are accelerated to extremely high energies of tera electron Volt in the immediate vicinity of a supermassive black hole and then emit the observed gamma rays.

Public Release: 1-Jul-2009 Nature Plants save the earth from an icy doom
Fifty million years ago, the North and South poles were ice-free and crocodiles roamed the Arctic. Since then, a long-term decrease in the amount of CO2 in the atmosphere has cooled the Earth. Researchers at Yale University, the Carnegie Institution of Washington and the University of Sheffield now show that land plants saved the Earth from a deep frozen fate by buffering the removal of atmospheric CO2 over the past 24 million years.

Public Release: 29-Jun-2009 Story tips from the US Department of Energy's Oak Ridge National Laboratory, July 2009
Researchers have developed an innovative cooling concept that could improve vehicle performance, life expectancy and overall efficiency without increasing costs. Alumina-forming austenitic stainless steels boast an increased upper-temperature oxidation, or corrosion, limit that is 100 to 400 degrees Fahrenheit higher than that of conventional stainless steels. A new explosives detector with incredible sensitivity and a range of up to 100 meters could save lives and thwart the efforts of terrorists.
Public Release: 29-Jun-2009 Physical Review D Fermilab's CDF observes Omega-sub-b baryon
At a recent physics seminar at the US Department of Energy's Fermi National Accelerator Laboratory, Fermilab physicist Pat Lukens of the CDF experiment announced the observation of a new particle, the Omega-sub-b (Ωb). The particle contains three quarks, two strange quarks and a bottom quark (s-s-b). It is an exotic relative of the much more common proton, and has about six times the proton's mass.

Public Release: 29-Jun-2009 Physical Review Letters NuTeV anomaly helps shed light on physics of the nucleus
A new calculation clarifies the complicated relationship between protons and neutrons in the atomic nucleus and offers a fascinating resolution of the famous NuTeV Anomaly. The calculation, published in the journal Physical Review Letters on June 26, was carried out by a collaboration of researchers from the Department of Energy's Thomas Jefferson National Accelerator Facility, Tokai University and the University of Washington.

Public Release: 26-Jun-2009 FSU research group wins $1 million grant to study nuclear fuels
A Florida State University researcher has received a $1 million, five-year grant from the US Department of Energy for a study that could lead to the design of better nuclear fuels and safer and more efficient reactors to generate nuclear power.

Public Release: 25-Jun-2009 SRNL to study applicability of solar cell coatings
A project under way at the US Department of Energy's Savannah River National Laboratory will study how special coatings that mimic structures found in nature can increase the usefulness of solar energy as a vital part of the nation's future energy strategy.

Public Release: 23-Jun-2009 Nano Letters Salt block unexpectedly stretches in Sandia experiments
To stretch a supply of salt generally means using it sparingly.
But researchers from Sandia National Laboratories and the University of Pittsburgh were startled when they found they had made the solid actually physically stretch.
Public Release: 22-Jun-2009 Proceedings of the National Academy of Sciences Bioengineers develop a microfabricated device to measure cellular forces during tissue development
A Penn-led collaboration studying the physical forces generated by cells has created a tiny micron-sized device that measures and manipulates cellular forces as assemblies of living cells reorganize themselves into tissues.

Green chemistry: Using lasers to detect explosives and hazardous waste
Berkeley Lab scientists are pioneering laser ablation techniques that can detect explosives and hazardous waste in seconds, with no chemical waste. The technology can save the lives of soldiers, keep children safe from toys illegally coated with lead paints, and protect workers from chemical poisoning.
Ames Laboratory-made materials are out of this world
Materials produced at the US Department of Energy's Ames Laboratory were launched into space on May 14 with the European Space Agency's Planck Mission. Ames Laboratory's Materials Preparation Center synthesized over 20 kilograms of a lanthanum-nickel-tin alloy for use in a metallic hydride sorption cryocooler system -- built by NASA's Jet Propulsion Laboratory -- that will cool instruments during the space mission.
