Scientists in the STAR collaboration at the Relativistic Heavy Ion Collider, a particle accelerator exploring nuclear physics and the building blocks of matter at the U.S. Department of Energy's Brookhaven National Laboratory, have new evidence for what's called a "chiral magnetic wave" rippling through the soup of quark-gluon plasma created in RHIC's energetic particle smashups. The findings are described in a paper that will be highlighted as an Editors' Suggestion in Physical Review Letters.
Biofuels pioneer Mascoma LLC and the Department of Energy's BioEnergy Science Center have developed a revolutionary strain of yeast that could help significantly accelerate the development of biofuels from nonfood plant matter.

Researchers at the U.S. Department of Energy's Princeton Plasma Physics Laboratory (PPPL) have for the first time simulated the formation of structures called "plasmoids" during Coaxial Helicity Injection (CHI), a process that could simplify the design of fusion facilities known as tokamaks. Researchers at the U.S. Department of Energy's Princeton Plasma Physics Laboratory (PPPL) have for the first time simulated the formation of structures called "plasmoids" during Coaxial Helicity Injection (CHI), a process that could simplify the design of fusion facilities known as tokamaks. The findings, reported in the journal Physical Review Letters, involve the formation of plasmoids in the hot, charged plasma gas that fuels fusion reactions. These round structures carry current that could eliminate the need for solenoids - large magnetic coils that wind down the center of today's tokamaks - to initiate the plasma and complete the magnetic field that confines the hot gas.

There's an urgent demand for new antimicrobial compounds that are effective against constantly emerging drug-resistant bacteria. Two robotic chemical-synthesizing machines at the Molecular Foundry have joined the search.
A new study predicts that researchers could use spiraling pulses of laser light to change the nature of graphene, turning it from a metal into an insulator and giving it other peculiar properties that might be used to encode information.
In a new twist on the use of DNA in nanoscale construction, scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory and collaborators put synthetic strands of the biological material to work in two ways: They used ropelike configurations of the DNA double helix to form a rigid geometrical framework, and added dangling pieces of single-stranded DNA to glue nanoparticles in place.
Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have just taken a big step toward the goal of engineering dynamic nanomaterials whose structure and associated properties can be switched on demand. In a paper appearing in Nature Materials, they describe a way to selectively rearrange the nanoparticles in three-dimensional arrays to produce different configurations, or phases, from the same nano-components.
This new result has allowed researchers to determine the reason behind a large discrepancy in the data between two different methods used to measure the proton's electric form factor.
Study shows how heavy-ion induced atomic-scale defects in iron-based superconductors "pin" potentially disruptive quantum vortices, enabling high currents to flow unimpeded. The study opens a new way forward for designing and understanding superconductors that can operate in demanding high-current, high magnetic field applications, such as zero-energy-loss power transmission lines and energy-generating turbines.
Scientists for the first time have precisely measured a protein's natural "knee-jerk" reaction to the breaking of a chemical bond - a quaking motion that propagated through the protein at the speed of sound.
Using a "roadmap" of theoretical calculations and supercomputer simulations performed by Berkeley Lab's Daniel Kasen, astronomers observed a flash of light caused by a supernova slamming into a nearby star, allowing them to determine the stellar system from which a Type Ia supernova was born. This finding confirms one of two competing theories about Type Ia supernovae birth.
