Genome-wide rice studies yield first major, large-scale collection of mutations for grass model crops, vital to boosting biofuel production.
A Columbia team has definitively observed an intensely studied anomaly in condensed matter physics--the even-denominator fractional quantum Hall state--via transport measurement in bilayer graphene. "Observing the 5/2 state in any system is a remarkable scientific opportunity, since it encompasses some of the most perplexing concepts in modern condensed matter physics, such as emergence, quasi-particle formation, quantization, and even superconductivity ...[It may have] great potential for real-world applications, particularly in quantum computing."

An international team including DOE Joint Genome Institute researchers analyzed the genome sequence of the common liverwort (Marchantia polymorpha) to identify genes and gene families deemed crucial to plant evolution and have been conserved over millions of years and across plant lineages.
Using a simple layer-by-layer coating technique, researchers from the U.S. and Korea have developed a paper-based flexible supercapacitor that could be used to help power wearable devices. The device uses metallic nanoparticles to coat cellulose fibers in the paper, creating supercapacitor electrodes with high energy and power densities - and the best performance so far in a textile-based supercapacitor.
A new method for capturing radioactive waste from nuclear power plants is cheaper and more effective than current methods, a potential boon for the energy industry, according to new research published in the journal Nature Communications.
A method developed by Oak Ridge National Laboratory could protect connected and autonomous vehicles from possible network intrusion. A new ORNL technique makes ultrafast measurements using atomic force microscopy.
SLAC Invention Could Lead to Novel Terahertz Light Sources That Help Us See the World with Different Eyes
Ever since the discovery of X-rays in 1895, their ability to reveal things hidden to the human eye has created endless opportunities. But X-rays by far aren't the only option to see the world with different eyes. Researchers hope to make better use of a different form of light, called terahertz radiation, which has broad applications in science, radar, security, medicine and communications.
Researchers from Berkeley Lab, Lawrence Livermore Lab and UC Davis are building the first-ever end-to-end simulation code to precisely capture the geology and physics of regional earthquakes, and how the shaking impacts buildings
When a normally cold stream in Iceland was warmed, the make-up of life inside changed as larger organisms thrived while smaller ones struggled. The findings carry implications for life in a warming climate.
As microchips become smaller and faster, the shrinking size of their copper interconnects leads to increased electrical resistivity at the nanoscale. Finding a solution to this technical bottleneck is a problem for the semiconductor industry; one possibility involves reducing the resistivity size effect by altering the crystalline orientation of interconnect materials. Researchers conducted electron transport measurements in epitaxial single-crystal layers of tungsten as one potential solution. The work is published in this week's Journal of Applied Physics.
In Nature Methods, a team including DOE JGI researchers described the results of the Critical Assessment of Metagenome Interpretation (CAMI) Challenge, the first-ever, community-organized benchmarking assessment of computational tools for metagenomes.
To take full advantage of biomass, lignin needs to be processed into usable components along with the plant cellulose. Ames Laboratory scientists are working to develop a method to deconstruct lignin in a way that is economically feasible and into stable, readily useful components.
Scientists set record resolution for patterning materials at sizes as small as a single nanometer using microscope-based lithography.
Big impacts on crystal formation result from small changes and reveal design principles for new materials for solar cells, more.
For the first time, self-organized, soft machines powered by molecular motors propelled fluid for hours across meters.
UPTON, NY--Chemists at the U.S. Department of Energy's Brookhaven National Laboratory have designed a new catalyst that speeds up the rate of a key step in "artificial photosynthesis"--an effort to mimic how plants, algae, and some bacteria harness sunlight to convert water and carbon dioxide into energy-rich fuels.
Picture two schools of fish swimming in clockwise and counterclockwise circles. It's enough to make your head spin, and now scientists at Rutgers University-New Brunswick and the University of Florida have discovered the "chiral spin mode" - a sea of electrons spinning in opposing circles.
Scientists from the Stanford PULSE Institute at the Department of Energy's SLAC National Accelerator Laboratory have found a potential new way to make attosecond laser pulses using ordinary glass - in this case, the cover slip from a microscope slide.
Nano-scale modeling of piezoelectric energy harvester offers a new nano-scale sensor design and demonstrates important design elements for efficient implementation.
Students returning to school this Fall may not think much about the significant amount of energy it takes to keep the lights on and their classroom smartboards operating, but principals, superintendents, and building managers are taking note. According to the EPA, schools nationwide spend $8 billion a year on energy - second only to personnel in K-12 operating budgets.
Researchers at the Department of Energy's (DOE) Argonne National Laboratory have moved the development process into the passing lane. For the first time, Argonne's scientists and engineers pinpointed engine designs for a given fuel using the Mira supercomputer at the heart of the Argonne Leadership Computing Facility (ALCF), a DOE Office of Science User Facility.
Using X-ray techniques, scientists are developing an analysis tool that can more accurately predict how sulfur compounds in a batch of crude oil might corrode equipment- an important safety issue for the oil industry.
A University of Wisconsin-Madison physicist and his colleagues are turning IceCube, the world's most sensitive neutrino telescope, to the task of helping demystify powerful pulses of radio energy generated up to billions of light-years from Earth.
A new type of "bijel" created by Berkeley Lab scientists could one day lead to applications in soft robotics, liquid circuitry, and energy conversion.
Eat too much without exercising and you'll probably put on a few pounds. As it turns out, plant leaves do something similar. In a new study at the U.S. Department of Energy's Brookhaven National Laboratory, scientists show that retaining sugars in plant leaves can make them get fat too. In plants, this extra fat accumulation could be a good thing.
