Simulation sets atoms shivering
(Phys.org) —In "Harry Potter and the Sorcerer's Stone" (JK Rowling, 1997), Harry, Ron, and Hermione encounter a massive stone chessboard, one of many obstacles in their path. To advance, they must play, ...
Life on Mars hopes fade after methane findings (Update)
Hopes of finding life on Mars suffered a setback after new findings from NASA's Curiosity rover detected only trace amounts of methane gas in the Red Planet's atmosphere, a study said Thursday.
The Drake Equation revisited: An interview with Sara Seager
Planet hunters keep finding distant worlds that bear a resemblance to Earth. Some of the thousands of exoplanet candidates discovered to date have similar sizes or temperatures. Others possess rocky surfaces ...
SDO mission untangles motion inside the Sun
(Phys.org) —Using an instrument on NASA's Solar Dynamics Observatory, called the Helioseismic and Magnetic Imager, or HMI, scientists have overturned previous notions of how the sun's writhing insides move ...
Water in a Martian desert
Craters once brim-full with sediments and water have long since drained dry, but traces of their former lives as muddy lakes cling on in the Martian desert.
Research team solves Martian meteorite age puzzle
By directing energy beams at tiny crystals found in a Martian meteorite, a Western University-led team of geologists has proved that the most common group of meteorites from Mars is almost 4 billion years younger than many ...
Imaging electron pairing in a simple magnetic superconductor
In the search for understanding how some magnetic materials can be transformed to carry electric current with no energy loss, scientists at the U.S. Department of Energy's Brookhaven National Laboratory, ...
NASA Mars rover Curiosity begins delayed road trip
It took longer than expected, but NASA's Curiosity rover is finally heading toward a Martian mountain.
When calculating cell-growth thermodynamics, reconsider using the Gibbs free energy equation
A forthcoming article in The Quarterly Review of Biology provides the basis for an argument against using the Gibbs free energy equation to accurately determine the thermodynamics of microbial growth.
Study explores atmospheric impact of declining Arctic sea ice
There is growing recognition that reductions in Arctic sea ice levels will influence patterns of atmospheric circulation both within and beyond the Arctic. New research in the International Journal of Climatology explores the im ...
Uneven warming shifts equatorial rain band, midlatitude westerlies
In a band near the equator, southward Northern Hemisphere winds and northward Southern Hemisphere winds come together to form the Intertropical Convergence Zone (ITCZ). In the ITCZ the equatorward winds rise and cool, creating ...
