Cassini sees sunny seas on Titan
(Phys.org) —As it soared past Saturn's large moon Titan recently, NASA's Cassini spacecraft caught a glimpse of bright sunlight reflecting off hydrocarbon seas.
Spin-based electronics: New material successfully tested
Spintronics is an emerging field of electronics, where devices work by manipulating the spin of electrons rather than the current generated by their motion. This field can offer significant advantages to ...
Study suggests large waves may have bigger role in breaking up polar sea ice than thought
Magnetic topological insulators are 1,000 times more energy-efficient for switching
(Phys.org) —Topological insulators are an emerging class of materials that act as both insulators and conductors, and could potentially be used in smartphones, computers and other electronic devices.
Radiation from early universe found key to answer major questions in physics
(Phys.org) —Astrophysicists at UC San Diego have measured the minute gravitational distortions in polarized radiation from the early universe and discovered that these ancient microwaves can provide an ...
Today's Antarctic region once as hot as California, Florida
Parts of ancient Antarctica were as warm as today's California coast, and polar regions of the southern Pacific Ocean registered 21st-century Florida heat, according to scientists using a new way to measure ...
Researchers open path to finding rare, polarized metals
Drexel University researchers are turning some of the basic tenets of chemistry and physics upside down to cut a trail toward the discovery of a new set of materials. They're called "polar metals" and, according ...
New system could provide first method for filtering light waves based on direction
Light waves can be defined by three fundamental characteristics: their color (or wavelength), polarization, and direction. While it has long been possible to selectively filter light according to its color ...
Antarctic moss lives after 1,500 years under ice
Researchers from the British Antarctic Survey and University of Reading report in Current Biology on March 17 that Antarctic mosses can essentially come back to life after 1,500 completely inactive years ...
