No more zigzags: Scientists uncover mechanism that stabilizes fusion plasmas

(DOE/Princeton Plasma Physics Laboratory) Article describes simulation of mechanism that eliminates sawtooth instabilities in fusion plasmas.

Mathematicians receive high honors for global contributions

(Society for Industrial and Applied Mathematics) 16 distinguished individuals are being recognized by Society for Industrial and Applied Mathematics (SIAM) for their exemplary research, significant contributions, and outstanding service to the applied mathematics and computational science communities.

UTA regional assessment shows segregation, challenges

(University of Texas at Arlington) After extensively analyzing fair housing in North Texas, UTA researchers have discovered that in many cases, segregation and associated problems are becoming more pronounced.

Close-ups of grain boundaries reveal how sulfur impurities make nickel brittle

(University of California - San Diego) Engineers at the University of California San Diego have shed new light on a scientific mystery regarding the atomic-level mechanism of the sulfur embrittlement of nickel, a classic problem that has puzzled the scientific community for nearly a century. The discovery also enriches fundamental understanding of general grain boundaries that often control the mechanical and physical properties of polycrystalline materials.

Solutions to water challenges reside at the interface

(American Institute of Physics) Leading Argonne National Laboratory researcher Seth Darling describes the most advanced research innovations that could address global clean water accessibility. His comprehensive paper focuses on understanding and controlling the interfaces between materials and water.

GPM satellite sees Tropical Cyclone Son-Tinh dropping rain in the Philippines

(NASA/Goddard Space Flight Center) As Tropical Depression 11W was strengthening into Tropical Storm Son-tinh near the northern Philippines, the Global Precipitation Measurement mission or GPM core satellite analyzed its rainfall.

Researchers enable transmission of specific colors of light over long distances

(University of North Carolina at Chapel Hill) Researchers from the University of North Carolina at Chapel Hill have reached a new milestone on the way to optical computing, or the use of light instead of electricity for computing. They explored a new way to select and send light of a specific color using long silicon wires that are several hundred nanometers in diameter and their work enabled a new type of nanoscale "light switch" that can turn on and off the transmission of one color of light over very long distances.

World's largest computing association updates code of ethics

(Association for Computing Machinery) After a two-year process that included extensive input from computing professionals around the world, ACM, the Association for Computing Machinery, has updated its Code of Ethics and Professional Conduct. The revised Code of Ethics addresses the significant advances in computing technology and the growing pervasiveness of computing in all aspects of society since it was last updated in 1992.

Gold nanoparticles to find applications in hydrogen economy

(Peter the Great Saint-Petersburg Polytechnic University) The international team of scientist of Peter the Great St. Petersburg Polytechnic University (SPbPU), Leibniz University Hannover (Leibniz Universität Hannover) and the Ioffe Institute found a way to improve nanocomposite material which opens new opportunities to use it in hydrogen economy and other industries. The study is dedicated to the composite material, a semiconductor based on titanium dioxide. Its applications are widely studied by the researchers all over the world.

Brixon, Inc. licenses ORNL's innovative sensor technology for security applications

(DOE/Oak Ridge National Laboratory) Brixon, Inc., has exclusively licensed a multiparameter sensor technology from the Department of Energy's Oak Ridge National Laboratory. The integrated platform uses various sensors that measure physical and environmental parameters and respond to standard security applications.
