New solar cell technology captures high-energy photons more efficiently
(Phys.org) —Getting the blues is rarely a desirable experience—unless you're a solar cell, that is.
Champion nano-rust for producing solar hydrogen
EPFL and Technion researchers have figured out the "champion" nanostructures able to produce hydrogen in the most environmentally friendly and cheap manner, by simply using daylight.
Researchers calculate radiation exposure associated with journey to Mars
On November 26, 2011, the Mars Science Laboratory began a 253-day, 560-million-kilometer journey to deliver the Curiosity rover to the Red Planet. En route, the Southwest Research Institute-led Radiation ...
Cirrus clouds form around mineral dust and metallic particles, study finds
At any given time, cirrus clouds—the thin wisps of vapor that trail across the sky—cover nearly one-third of the globe. These clouds coalesce in the upper layers of the troposphere, often more than 10 ...
8th century gamma ray burst irradiated the Earth, study finds
(Phys.org)—A nearby short duration gamma-ray burst may be the cause of an intense blast of high-energy radiation that hit the Earth in the 8th century, according to new research led by astronomers Valeri ...
Houston, we have another problem: Study shows space travel is harmful to the brain
(Phys.org)—As if space travel was not already filled with enough dangers, a new study out today in the journal PLOS ONE shows that cosmic radiation – which would bombard astronauts on deep space missio ...
Flexible silicon solar-cell fabrics may soon become possible
For the first time, a silicon-based optical fiber with solar-cell capabilities has been developed that has been shown to be scalable to many meters in length. The research opens the door to the possibility ...
Clear link between solar activity and winter weather revealed
Scientists have demonstrated a clear link between the 11-year sun cycle and winter weather over the northern hemisphere for the first time.
New technology uses solar UV to disinfect drinking water
(PhysOrg.com) -- A team of Purdue University researchers has invented a prototype water-disinfection system that could help the world's 800 million people who lack safe drinking water.
Metal particle generates new hope for H2 energy
(PhysOrg.com) -- Tiny metallic particles produced by University of Adelaide chemistry researchers are bringing new hope for the production of cheap, efficient and clean hydrogen energy.
Dwarf planet Haumea shines with crystalline ice
The fifth dwarf planet of the Solar System, Haumea, and at least one of its two satellites, are covered in crystalline water-ice due to the tidal forces between them and the heat of radiogenic elements. This ...
Superman's solar-powered feats break a fundamental law of physics
It goes without saying that Superman can accomplish some pretty spectacular feats. But according to students, the Man of Steel actually achieves the impossible – by breaking the fundamental physics law of conservation of ...
Study says Arctic melt season lengthening, ocean rapidly warming
The length of the melt season for Arctic sea ice is growing by several days each decade, and an earlier start to the melt season is allowing the Arctic Ocean to absorb enough additional solar radiation in ...
Comet ISON pronounced dead: Sun is chief suspect (Update)
Comet ISON, once optimistically called the comet of the century, is dead, the victim of a way-too-close brush with the sun. It was barely a year old.
