Ozone depletion trumps greenhouse gas increase in jet-stream shift
Depletion of Antarctic ozone is a more important factor than increasing greenhouse gases in shifting the Southern Hemisphere jet stream in a southward direction, according to researchers at Penn State.
NASA's older Mars rover notches another milestone
Opportunity, NASA's other Mars rover, has tooled around the red planet for so long it's easy to forget it's still alive.
Road trip on tap for NASA's Mars rover in new year (Update)
Since captivating the world with its acrobatic landing, the Mars rover Curiosity has fallen into a rhythm: Drive, snap pictures, zap at boulders, scoop up dirt. Repeat.
At last, how many alien civilizations are there?
During the space age, 1961 was a special year: the Russian cosmonaut Yuri Gagarin became the first man to orbit Earth, while the American astronomer Frank Drake developed the now famous Drake Equation. This ...
Size matters for fish in a changing climate
A changing climate could have a drastic impact on fish populations in the tropics, but according to new research it's likely to boost stocks in some cooler waters.
Outside a vacuum: Model predicts movement of charged particles in complex media
Picture two charged particles in a vacuum. Thanks to laws of elementary electrostatics, we can easily calculate the force these particles exert upon one another, and therefore predict their movements.
Metamaterials and transformation optics control light on a microchip
Using a combination of the new tools of metamaterials and transformation optics, engineers at Penn State University have developed designs for miniaturized optical devices that can be used in chip-based optical ...

USA's ancient hurricane belt and the US-Canada equator
The recent storms that have battered settlements on the east coast of America may have been much more frequent in the region 450 million years ago, according to scientists.
Astrophysicist suggests planetary misalignment due to multiple star impact
Keck observations bring weather of Uranus into sharp focus
(Phys.org)—In 1986, when Voyager swept past Uranus, the probe's portraits of the planet were "notoriously bland," disappointing scientists, yielding few new details of the planet and its atmosphere, and ...
Loopholes discovered in Sun's magnetic belt
(Phys.org)—The mystery surrounding how an electrically charged solar wind can be unleashed from around the Sun's equator – an area where strong magnetic fields should strap it to the surface – has ...
Chasing clouds on Venus
(Phys.org)—Clouds regularly punctuate Earth's blue sky, but on Venus the clouds never part, for the planet is wrapped entirely in a 20 km-thick veil of carbon dioxide and sulphuric dioxide haze.
Temperatures measured at Gale Crater higher than expected
(Phys.org)—Preliminary weather reports from the Curiosity's Remote Environment Monitoring Station (REMS) are showing some surprisingly mild temperatures during the day. Average daytime air temperatures ...
