Coming to a lab bench near you: Femtosecond X-ray spectroscopy
Berkeley Lab researchers have, for the first time, captured the ephemeral electron movements in a transient state of a chemical reaction using ultrafast, tabletop X-ray spectroscopy. The researchers used femtosecond pulses of X-ray light to catch the unraveling of a ring molecule that is important in biochemical and optoelectronic processes.

Discovered: Novel group of giant viruses
Viruses are thought to outnumber the microbes on Earth; both outnumber the stars in the Milky Way. A handful of giant viruses have been discovered in the past two decades, and in Science, DOE Joint Genome Institute scientists report a novel group of giant viruses with a more complete set of translation machinery genes than any other virus known to date. They believe that this discovery significantly increases our understanding of viral evolution.

Predicting the limits of friction: Sandia looks at properties of material
Sandia National Laboratories materials scientists have developed a model to predict the limits of friction behavior of metals based on materials properties -- how hard you can push on materials or how much current you can put through them before they stop working properly.

Story tips from the Department of Energy's Oak Ridge National Laboratory, April 2017
An ORNL-led team is bringing together quantum, high-performance and neuromorphic computing architectures to address complex issues that, if resolved, could clear the way for more flexible, efficient technologies in intelligent computing; ORNL is using electron beam precision to instantly adhere cathode coatings for lithium-ion batteries; ORNL created an approach to get a better look at plant cell wall characteristics at high resolution as they create more efficient, less costly methods to deconstruct biomass.

Built from the bottom up, nanoribbons pave the way to 'on-off' states for graphene
A new way to grow narrow ribbons of graphene, a lightweight and strong structure of single-atom-thick carbon atoms linked into hexagons, may address a shortcoming that has prevented the material from achieving its full potential in electronic applications. Graphene nanoribbons, mere billionths of a meter wide, exhibit different electronic properties than two-dimensional sheets of the material. 'Confinement changes graphene's behavior,' said An-Ping Li, a physicist at the Department of Energy's Oak Ridge National Laboratory.

Jefferson Lab accomplishes critical milestones toward completion of 12 GeV upgrade
CEBAF at the US Department of Energy's Thomas Jefferson National Accelerator Facility has achieved two major commissioning milestones and is now entering the final stretch of work to conclude its first major upgrade. Recently, the CEBAF accelerator delivered electron beams into two of its experimental halls at energies not possible before the upgrade for commissioning of the experimental equipment currently in each hall.

The economic case for wind and solar energy in Africa
To meet skyrocketing demand for electricity, African countries may have to triple their energy output by 2030. While hydropower and fossil fuel power plants are favored approaches in some quarters, a new assessment by the Lawrence Berkeley National Laboratory has found that wind and solar can be economically and environmentally competitive options and can contribute significantly to the rising demand.

Cryo-electron microscopy achieves unprecedented resolution using new computational methods
Cryo-electron microscopy (cryo-EM)--which enables the visualization of viruses, proteins, and other biological structures at the molecular level--is a critical tool used to advance biochemical knowledge. Now Berkeley Lab researchers have extended cryo-EM's impact further by developing a new computational algorithm instrumental in constructing a 3-D atomic-scale model of bacteriophage P22 for the first time.

Less radiation in inner Van Allen belt than previously believed
The inner Van Allen belt has less radiation than previously believed, according to a recent study in the Journal of Geophysical Research. Observations from NASA's Van Allen probes show the fastest, most energetic electrons in the inner radiation belt are actually much rarer and harder to find than scientists expected. This is good news for spacecraft that are orbiting in the region and can be damaged by high levels of radiation.

'Flying saucer' colloidal quantum dots produce brighter, better lasers
A multi-institutional team of researchers from Canada and the US has demonstrated steady state lasing with solution-processed nanoparticles called 'colloidal quantum dots,' an important step on the path to improving laser tools for fiber optics, video projectors and more accurate medical testing technology. The work is reported today in a paper for the journal Nature.
