Until now, climate change scenarios were developed and applied sequentially. The scenarios began with societal and economic factors that influence greenhouse gas emissions, then atmospheric processes, and finally impacts.
Desktop experiments could point the way to dark matter discovery, complementing grand astronomical searches and deep underground observations. According to recent results from theorists from the Stanford Institute for Materials and Energy Science, a joint institute of the Department of Energy’s SLAC National Accelerator Laboratory and Stanford University, small blocks of matter on a tabletop could reveal elusive properties of the as-yet-unidentified dark matter particles that make up a quarter of the universe, potentially making future large-scale searches easier.
The very traits that can make some bamboos troublesome for landowners—quick to grow and hard to kill—make it potentially useful for cleanup, according to the Savannah River National Laboratory.
“We are looking at numerous kinds of vegetation to plant on waste site closure caps,” said Dr. Eric Nelson of SRNL.
Using the latest in aberration-corrected electron microscopy, researchers at the DOE's's Oak Ridge National Laboratory and their colleagues have obtained the first images that distinguish individual light atoms such as boron, carbon, nitrogen and oxygen.
The ORNL images were obtained with a Z-contrast scanning transmission electron microscope (STEM).
