Relativistic heavy ion collider smashes record for polarized proton luminosity
Thanks to accelerator advances, the Relativistic Heavy Ion Collider, a powerful nuclear physics research facility at the US Department of Energy's Brookhaven National Laboratory, just shattered its own record for producing polarized proton collisions at 200-giga-electron-volt collision energy. The improvement will generate high volumes of data rapidly, giving physicists time to achieve several high-priority science goals in a single run at Relativistic Heavy Ion Collider.

New 'cool roof time machine' will accelerate cool roof deployment
A collaboration led by Berkeley Lab scientists has established a method to simulate in the lab the soiling and weathering of roofing materials, reproducing in only a few days the solar reflectance of roofing products naturally aged for three years. Now this protocol has been approved by American Society for Testing and Materials International as a standard practice for the industry.

Dark Energy Survey creates detailed guide to spotting dark matter
Scientists on the Dark Energy Survey have released the first in a series of dark matter maps of the cosmos. These maps, created with one of the world's most powerful digital cameras, are the largest contiguous maps created at this level of detail and will improve our understanding of dark matter's role in the formation of galaxies.

Erupting electrodes: How recharging leaves behind microscopic debris inside batteries
An eruption of lithium at the tip of a battery's electrode, cracks in the electrode's body, and a coat forming on the electrode's surface reveal how recharging a battery many times leads to its demise. Using a powerful microscope to watch multiple cycles of charging and discharging under real battery conditions, researchers have gained insight into the chemistry that clogs rechargeable lithium batteries in work appearing in the March issue of the journal Nano Letters.

Improved understanding of protein complex offers insight into DNA replication initiation mechanism basics
A clearer understanding of the origin recognition complex -- a protein complex that directs DNA replication -- through its crystal structure offers new insight into fundamental mechanisms of DNA replication initiation. This will also provide insight into how ORC may be compromised in a subset of patients with Meier-Gorlin syndrome, a form of dwarfism in humans.

US scientists celebrate the restart of the Large Hadron Collider
After two years of upgrades and repairs, proton beams once again circulate around the Large Hadron Collider at CERN. Oak Ridge National Laboratory has led an eight-year upgrade of the electromagnetic calorimeter used for LHC's experiment called ALICE (for A Large Ion Collider Experiment). This detector measures the energies of high-energy electrons and gamma rays to learn more about the conditions of the early universe.

Story tips from the Department of Energy's Oak Ridge National Laboratory, April 2015
By studying fish and invertebrates in a creek with known mercury contamination, researchers are gaining a better understanding of the relationship between the toxin in the stream and bioaccumulation in organisms. While mercury concentrations in East Fork Poplar Creek in Oak Ridge, Tenn., have decreased significantly over the last 30 years, levels in tissue from fish have remained the same or increased. To understand why, a team led by Monica Poteat of Oak Ridge National Laboratory is examining the intricacies of the food chain and the biodiversity of the stream at locations about 10 kilometers apart.

New research project to study how tropical forests worldwide respond to climate change
Tropical forests play major roles in regulating Earth's climate, but there are large uncertainties over how they'll respond over the next 100 years as the planet's climate warms. An expansive new project led by scientists from Berkeley Lab aims to bring the future of tropical forests and the climate system into much clearer focus. The project is called the Next Generation Ecosystem Experiments-Tropics, or NGEE-Tropics.

Longer DNA fragments reveal rare species diversity
A challenge in metagenomics is that the more commonly used sequencing machines generate data in short lengths, while short-read assemblers may not be able to distinguish among multiple occurrences of the same or similar sequences, making it difficult to identify all the members in a microbial community. In the April 2015 issue of Genome Research, a team including DOE JGI researchers compared two ways of using next generation Illumina sequencing machines to help with this.

Goodbye, range anxiety? Electric vehicles may be more useful than previously thought
In the first study of its kind, scientists at Lawrence Berkeley National Laboratory quantitatively show that electric vehicles will meet the daily travel needs of drivers longer than commonly assumed. They found that batteries that have lost 20 percent of their originally rated energy storage capacity can still meet the daily travel needs of more than 85 percent of US drivers.

ORNL-led team demonstrates desalination with nanoporous graphene membrane
Desalination is an energy-intensive process, which concerns those wanting to expand its application. Now, a team of experimentalists led by the Department of Energy's Oak Ridge National Laboratory has demonstrated an energy-efficient desalination technology that uses a porous membrane made of strong, slim graphene -- a carbon honeycomb one atom thick. The results are published in the March 23 advance online issue of Nature Nanotechnology.
