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

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.
NASA satellites measure increase of Sun's energy absorbed in the Arctic
NASA satellite instruments have observed a marked increase in solar radiation absorbed in the Arctic since the year 2000 - a trend that aligns with the steady decrease in Arctic sea ice during the same period.
Physicist presents new observational solar weather model
Scientists now have an observational framework to help predict solar weather and how it will affect Earth.
Time-lapse photos and synched weather data unlock Antarctic secrets
In preparation for his upcoming fieldwork, Brown University research analyst Jay Dickson took 10,000 pictures of the inside of his freezer. He wasn't investigating disappearing food or making sure the light ...
Cosmic rays threaten future deep-space astronaut missions
Crewed missions to Mars remain an essential goal for NASA, but scientists are only now beginning to understand and characterize the radiation hazards that could make such ventures risky, concludes a new paper ...
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 ...
