Peering at the debris from particle collisions that recreate the conditions of the very early universe, scientists have for the first time measured the force of interaction between pairs of antiprotons. Like the force that holds ordinary protons together within the nuclei of atoms, the force between antiprotons is attractive and strong. The experiments were conducted at the Relativistic Heavy Ion Collider at Brookhaven National Laboratory and will publish in Nature.
Scientists from Stanford University and the Department of Energy's SLAC National Accelerator Laboratory have shown they can make flexible, transparent electrical conductors with record-high performance for use in solar cells, displays and other devices by spreading polymers on a clear surface with a tiny blade, like a knife spreading butter on toast.

A team of scientists, including several from the U.S. Department of Energy's Argonne National Laboratory, have determined the structures of several important tuberculosis enzymes, which could lead to new drugs for the disease.
A team led by Oak Ridge National Laboratory computed distributions in calcium-48, and revealed that the difference between the radii of neutron and proton distributions (called the "neutron skin") is considerably smaller than previously thought.
The recently commissioned MicroBooNE experiment at Fermi National Accelerator Laboratory has reached a major milestone: It detected its first neutrinos on Oct. 15, marking the beginning of detailed studies of these fundamental particles whose properties could be linked to dark matter, matter's dominance over antimatter in the universe and the evolution of the entire cosmos since the Big Bang.
The first-ever images of the protein complex that unwinds, splits, and copies double-stranded DNA reveal something rather different from the standard textbook view. The electron microscope images, created by scientists at the U.S. Department of Energy's Brookhaven National Laboratory with partners from Stony Brook University and Rockefeller University, offer new insight into how this molecular machinery functions.
Researchers in an Energy Frontier Research Center led by the Department of Energy's Oak Ridge National Laboratory are investigating ways to design structural materials that develop fewer, smaller flaws under irradiation.
Scientists from Stanford University and the Department of Energy's SLAC National Accelerator Laboratory have made the first direct images showing that electrical currents can flow along the boundaries between tiny magnetic regions of a material that normally doesn't conduct electricity. The results could have major implications for magnetic memory storage.
Researchers are sifting through an avalanche of data produced by one of the largest cosmological simulations ever performed, led by scientists at the U.S. Department of Energy's (DOE) Argonne National Laboratory. The simulation, run on the Titan supercomputer at DOE's Oak Ridge National Laboratory, modeled the evolution of the universe from just 50 million years after the Big Bang to the present day--from its earliest infancy to its current adulthood. Over the course of 13.8 billion years, the matter in the universe clumped together to form galaxies, stars and planets; but we're not sure precisely how.
Catalysts that power chemical reactions to produce the nylon used in clothing, cookware, machinery and electronics could get a lift with a new formulation that saves time, energy and natural resources.
Battery Mystery Solved: Atomic-Resolution Microscopy Answers Longstanding Questions About Lithium-Rich Cathode Material
Using complementary microscopy and spectroscopy techniques, researchers at Lawrence Berkeley National Laboratory (Berkeley Lab) say they have solved the structure of lithium- and manganese-rich transition metal oxides, a potentially game-changing battery material and the subject of intense debate in the decade since it was discovered.
Berkeley Lab researchers have developed metal-organic frameworks (MOFs) that feature flexible gas-adsorbing pores, giving them a high capacity for storing methane. This capability has the potential to help make the driving range of adsorbed-natural-gas (ANG) cars comparable to that of a typical gasoline-powered car.
Scientists have demonstrated that microwaves can help create nanostructured molybdenum disulfide (MoS2) catalysts with an improved ability to produce hydrogen. The microwave-assisted strategy accomplishes this by increasing the space, and therefore decreasing the interaction, between individual layers of MoS<sub>2</sub> nanosheets.
A team led by researchers from Brookhaven Lab and Cornell has characterized a key arrangement of electrons that may impede superconductivity in cuprates. Understanding this "electron density wave" may lead to ways to suppress or remove it to induce superconductivity, possibly even at room temperature.
A study published in Nature Communications suggests that the weather patterns known as El Nino and La Nina could lead to at least a doubling of extreme droughts and floods in California later this century.
Two new significant findings may move scientists closer to understanding the origins of tungsten-ditelluride's (WTe<sub>2</sub>) extremely large magnetoresistance, a key characteristic in modern electronic devices like magnetic hard drives and sensors. Scientists in Illinois recently discovered that tungsten-ditelluride (WTe<sub>2</sub>) is electronically three-dimensional with a low anisotropy.
Advances in ultrathin films have made solar panels and semiconductor devices more efficient and less costly, and researchers at the Department of Energy's Oak Ridge National Laboratory say they've found a way to manufacture the films more easily, too.
Engines, laptops and power plants generate waste heat. Thermoelectric materials can recover heat and improve energy efficiency. Scientists at Oak Ridge National Laboratory explored the fundamental physics of the world's best thermoelectric material.
The U.S. Department of Energy's Argonne National Laboratory this week released a pair of studies on the efficiency of shale oil production excavation. The reports show that shale oil production generates greenhouse gas emissions at levels similar to traditional crude oil production.
Research at the Department of Energy's SLAC National Accelerator Laboratory reveals new details about how tiny, burrowing sea organisms can influence the chemistry and structure of rocks where hydrocarbon deposits such as oil and gas are found.
Researchers from the University of Wisconsin at Madison are the first to grow self-directed graphene nanoribbons on the surface of the semiconducting material germanium. This allows the semiconducting industry to tailor specific paths for nanocircuitry in their technologies. Confirmation of the findings was done at Argonne's Center for Nanoscale Materials.
Scientists at the U.S. Department of Energy's Ames Laboratory have developed molecular modeling simulations and new theoretical formulations to help understand and optimize catalytic reactions that take place in chemical environments where the reactant "ingredients" for catalysis are not well mixed.
Thawing permafrost and contaminated sediment in marine coastal areas pose some of the greatest risks for the production of highly toxic methylmercury.
