November 2012 story tips

DOE/Oak Ridge National Laboratory
Peer-Reviewed Publication

Scientists have found that rising levels of ozone may amplify the impacts of higher temperatures and reduce streamflow from forests to rivers, streams and other water bodies. Recommendations to accelerate climate modeling to learn more about climate's regional ramifications and future effects. Research project to continue, providing additional data that could make houses of tomorrow even better. Ethanol blends of 10 to 25 percent could potentially have more fuel pump compatibility issues than higher blends.

ORNL debuts Titan supercomputer

DOE/Oak Ridge National Laboratory
Peer-Reviewed Publication

The Oak Ridge National Laboratory launched a new era of scientific supercomputing today with Titan, a system capable of churning through more than 20,000 trillion calculations each second--or 20 petaflops--by employing a family of processors called graphic processing units first created for computer gaming. Titan will be 10 times more powerful than ORNL's last world-leading system, Jaguar.

Neutron experiments give unprecedented look at quantum oscillations
