Broadband and ultrathin polarization manipulators developed
A research team in South Korea has developed a technology that can manipulate a polarized light in broadband operation with the use of a metamaterial.
Agency proposes critical habitat for ringed seals
A federal agency has proposed about 350,000 square miles of ocean off Alaska's north and west coasts as critical habitat for the seal that's the main prey of polar bears.
Arctic conditions may become critical for polar bears by end of 21st century
Shifts in the timing and duration of ice cover, especially the possible lengthening of ice-free periods, may impact polar bears under projected warming before the end of the 21st century, according to a study ...
Polar Code too weak to properly protect polar environments from increased shipping activity
Responding to today's adoption by the International Maritime Organisation of the long-awaited Polar Code, aimed at regulating shipping in Polar Regions, a coalition of environmental groups criticised the measures for not ...
Researchers engineer improvements of technology used in digital memory
The improvements in random access memory that have driven many advances of the digital age owe much to the innovative application of physics and chemistry at the atomic scale.
Researchers create 3-D stereoscopic color prints with nanopixels
Spiraling light, nanoparticles and insights into life's structure
(Phys.org) —As hands come in left and right versions that are mirror images of each other, so do the amino acids and sugars within us. But unlike hands, only the left-oriented amino acids and the right-oriented ...
Study: Polar bears disappearing from key region
A key polar bear population fell nearly by half in the past decade, a new U.S.-Canada study found, with scientists seeing a dramatic increase in young cubs starving and dying.
Researchers get first look at atom-thin boundaries
Scientists at the Department of Energy's Oak Ridge National Laboratory have made the first direct observations of a one-dimensional boundary separating two different, atom-thin materials, enabling studies ...
Rosetta: The dark side of the comet
(Phys.org) —Rosetta's scientific imaging system OSIRIS has caught a glimpse of the southern side of comet 67P/Churyumov-Gerasimenko. During the past months, this side has continuously faced away from the ...
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.
POLARBEAR seeks cosmic answers in microwave polarization
An international team of physicists has measured a subtle characteristic in the polarization of the cosmic microwave background radiation that will allow them to map the large-scale structure of the universe, ...
Is Australia's claim to Antarctica at risk?
While Australia's commitment to a 20-year plan for Antarctica has been welcomed by some it has also raised concerns over the nation's ability to fulfil a credible research role in the south polar region.
Feds: Don't expect winter to be polar vortex redux
(AP)—Federal forecasters don't expect a return of frequent cold blasts from the polar vortex this winter. Nor should the weather system that blocked rain from California last winter come back.
