Tide Pools Mimic Climate Change in Everyday Cycle
Researchers unexpectedly discovered that tiny shoreline ecosystems act as miniature laboratories in which ocean acidification and its effects play out nightly.
Using Acid and Physical Force, Fungi Burrow Through Rock
Scientists observe the step-by-step process by which a fungus attacks a mineral to extract vital nutrients.
Icelandic Eruption Caused Record-Breaking Sulfur Dioxide Release
Satellite and ground-based data reveal sulfur dioxide flux, trace element release, and preeruption magma movement.
Characterizing the Fault Beneath the Marmara Sea
Researchers mine seismic wave data to elucidate the stress relief system of the Main Marmara Fault beneath Turkey's inland sea.
Electrical Concrete Offers Green Alternative to Airport Deicers
The Federal Aviation Administration is testing conductive concrete as a replacement for water-polluting chemicals used to melt ice from airport tarmacs.
Where Curiosity Has Taken Us
The Curiosity rover, one of NASA's flagship missions, analyzes Martian geology, geochemistry, climatology, and radiation to assess whether Mars could have supported microbial life.
Model of Solar Cycle's Impact on Climate Gets Upgrade
A new model of how the Sun's 11-year cycle affects climate leads to slight changes in model results on atmospheric chemistry, but temperature and wind results are consistent with the previous model.
Dating Lava Domes in California's Salton Trough
Scientists use a trio of techniques to resolve the age and duration of rhyolite volcanism of the Salton Buttes.
How Bat Breath and Guano Can Change the Shapes of Caves
Researchers working in caves in Borneo and elsewhere are finding evidence that biological processes shape many tropical caves by slowly eating away at surrounding rock.
