Unprecedented characterization of subsurface electronic states could lead to better semiconductors and seeing new interactions.
Black women with higher incomes are more likely to experience a forceful police interaction during a traffic stop, finds a new study from the Brown School at Washington University in St. Louis."We found that the likelihood of exposure to each type of police use of force was significantly greater for black females with incomes over $50,000," said Robert Motley Jr.
Using high-intensity pulses of infrared light, scientists found evidence of superconductivity associated with charge "stripes" in a material above the temperature at which it begins to transmit electricity without resistance--a finding that could help them design better high-temperature superconductors.
New composite materials make wind energy even greener by making the turbines themselves recyclable.

Scientists at the U.S. Department of Energy's Ames Laboratory have discovered a state of magnetism that may be the missing link to understanding the relationship between magnetism and unconventional superconductivity.
Smooth Sailing: PPPL Develops an Integrated Approach to Understand How to Better Control Plasma Instabilities
PPPL physicist Francesca Poli and coauthors recently published findings that describe an approach that for the first time simultaneously simulates the plasma, the magnetic islands, and the feedback control from waves that provide so-called electron cyclotron heating and current drive.
A team of researchers from ORNL's Energy and Transportation Science Division is using neutron imaging to study particulate filters that collect harmful emissions in vehicles. A better understanding of how heat treatments and oxidation methods can remove layers of soot and ash from these filters could lead to improved fuel-efficiency.
A research team led by the University of Georgia has discovered that manipulation of the same gene in poplar trees and switchgrass produced plants that grow better and are more efficiently converted to biofuels.
Today, the dome closes on the previous science chapters of the 4-meter Mayall Telescope in Arizona so that it can prepare for its new role in creating the largest 3-D map of the universe. This map could help to solve the mystery of dark energy, which is driving the accelerating expansion of the universe.
For the first time, scientists demonstrated a long-theorized nuclear effect called nuclear excitation by electron capture. This advance tests theoretical models that describe how nuclear and atomic realms interact and may also provide new insights into how star elements are created.
Searching for a power outlet may soon become a thing of the past. Instead, devices will receive electricity from a small metallic tab that, when attached to the body, is capable of generating electricity from bending a finger and other simple movements. That's the idea behind a collaborative research project led by University at Buffalo and Institute of Semiconductors (IoP) at Chinese Academy of Science (CAS).
Grover and GM colleagues Jian Gao, Venkatesh Gopalakrishnan, and Ramachandra Diwakar are using the Titan supercomputer at the Oak Ridge Leadership Computing Facility to improve combustion models for diesel passenger car engines with an ultimate goal of accelerating innovative engine designs while meeting strict emissions standards.
Nuclear physicists are using the nation's most powerful supercomputer, Titan, at the Oak Ridge Leadership Computing Facility (OLCF) to study particle interactions important to energy production in the Sun and stars and to propel the search for new physics discoveries. The research team using Titan, including principal investigator William Detmold of the Massachusetts Institute of Technology (MIT), is calculating proton-proton fusion--a process that powers the Sun and other stars in which two protons fuse to form a deuteron--and double beta decay, a rare process which occurs when an unstable nucleus decays by emitting two electrons with or without neutrinos (subatomic particles with near-zero mass).
Lithium -- It's Not Just for Batteries: The Powdered Metal Can Reduce Instabilities in Fusion Plasmas, Scientists Find
Scientists have found that lithium powder can eliminate instabilities known as edge-localized modes (ELMs) when used to coat a tungsten plasma-facing component called the "divertor."
A research team from Lawrence Livermore National Laboratory, the University of California, Berkeley and the University of Rochester have provided the first experimental evidence for superionic conduction in water ice at planetary interior conditions, verifying a 30-year-old prediction.
Michigan Tech researchers contend that tobacco farmers could increase profits by converting their land to solar farms, which in turn provides renewable energy generation.
A multi-institution team of scientists led by Texas A&M University chemist Sarbajit Banerjee has discovered an exceptional metal-oxide magnesium battery cathode material, moving researchers one step closer to delivering batteries that promise higher density of energy storage on top of transformative advances in safety, cost and performance in comparison to their ubiquitous lithium-ion (Li-ion) counterparts.
