(Phys.org)—The most common form of strokes are caused by a sudden reduction in blood flow to the brain (ischemia) that leads to an inadequate supply of oxygen and nutrients. These so-called ischemic strokes are one of the ...
Sunscreens, lotions, and cosmetics contain tiny metal nanoparticles that wash down the drain at the end of the day, or are discharged after manufacturing. Those nanoparticles eventually end up in agricultural soil, which ...
As the world's accessible oil reserves dwindle, natural gas has become an increasing important energy source. The primary component of natural gas is methane, which has the advantage of releasing less carbon dioxide when ...
(Phys.org) -- Superconductivity is a complex phenomenon that is considerably more intricate than many casual observers realize. This caveat applies equally to the subset of this research known as high-temperature superconductivity ...
(Phys.org) -- Researchers at the Center for Energy Research at UC San Diego recently demonstrated the best performance for solid oxide fuel cells (SOFCs) operating directly on ethanol without external reformation. The work ...
(Phys.org) -- Tiny particles of cerium oxide do not burn or change in the heat of a waste incineration plant. They remain intact on combustion residues or in the incineration system, as a new study by Swiss researchers from ...
Among terrorism scenarios that raise the most concern are attacks involving nuclear devices or materials. For that reason, technology that can effectively detect smuggled radioactive materials is considered vital to U.S. ...
A faint nightclub beat greets visitors to a small room housing the Localized Electron Atom Probe (LEAP). But that’s no stereo cranking out house music; it’s a rhythmic pump cooling a tiny sample to more than 220 ...
(AP) -- China announced a cut Tuesday in its rare earths export quota as it tries to shore up sagging prices for the exotic metals used in mobile phones and other high-tech goods.
Scientists in the New York Center for Astrobiology at Rensselaer Polytechnic Institute have used the oldest minerals on Earth to reconstruct the atmospheric conditions present on Earth very soon after its birth. The findings, ...
