25-Jan-2016 How to find and study black holes
Black holes sound too strange to be real. But they are actually pretty common in space. There are dozens known and probably millions more in the Milky Way and a billion times that lurking outside. The makings and dynamics of these monstrous warpings of spacetime have been confounding scientists for centuries.
21-Jan-2016 Higher speed, more precision
In just a little over a year of operation, the US Department of Energy Ames Laboratory's dynamic nuclear polarization (DNP) solid-state nuclear magnetic resonance (NMR) spectrometer has successfully characterized materials at the atomic scale level with more speed and precision than ever possible before.
21-Jan-2016 Explore galaxies far, far away at internet speeds
Scientists have released an 'expansion pack' for a virtual tour of the universe that you can enjoy from the comfort of your own computer. The latest version of the publicly accessible images of the sky, which can be viewed using an interactive Sky Viewer tool, roughly doubles the size of the searchable universe from the project's original release in May.
21-Jan-2016 Facility staff and DOE computer scientists collaborate to speed up experimental data analysis
In early December, the US Department of Energy's (DOE) Brookhaven National Laboratory hosted the first in a series of week-long 'hackathons,' a code brainstorming session attended by nearly 40 computer scientists and software developers from several DOE Office of Science User Facilities, including those at Argonne, Berkeley, Oak Ridge and SLAC national laboratories.
19-Jan-2016 ORNL researchers use neutrons to gain insight into battery inefficiency
Scientists at Oak Ridge National Laboratory are improving the lifetimes of rechargeable batteries that run on lithium, a small atom that can pack tightly into graphite anode materials. The valuable ions are depleted as a battery charges, and they are also lost to the formation of a thin coating on a battery's anode during initial charging. ORNL researchers used two powerful neutron science facilities to try to understand the dynamics behind this phenomenon.
15-Jan-2016 ORNL's thermal cameras snoop beneath surfaces to reveal materials' secrets
In 1995, the Department of Energy's Continuous Fiber Ceramic Composite program, led by Oak Ridge National Laboratory, bought a high-speed infrared camera -- one of the first available for purchase outside the military. Since then, ORNL has acquired at least 10 additional IR cameras for use in a spectrum of projects. The cameras have mapped changing temperatures as heat flows through objects from gears to artwork.
8-Jan-2016 SLAC's Stanley Brodsky shares Pomeranchuk Prize for theoretical physics

23-Dec-2015 Scratching the surface
Oceans cover almost three-quarters of the planet and are major contributors to atmospheric aerosols in the form of sea spray particles. These sea spray aerosols are rich in organic materials that impact cloud formation and the world's climate. Despite their abundance and significance, sea spray aerosols are not well understood. Researchers in collaboration with EMSL scientists are learning more about the chemistry of sea spray aerosols and their role in cloud formation to better account for them in climate models.
21-Dec-2015 Study forecasts disappearance of conifers due to climate change
A new study, led by Los Alamos National Laboratory, suggests that widespread loss of a major forest type, the pine-juniper woodlands of the Southwestern US, could be wiped out by the end of this century due to climate change, and that conifers throughout much of the Northern Hemisphere may be on a similar trajectory.
