A breath of Beijing air gets metagenomics treatment
Asian ozone pollution in Hawaii is tied to climate variability
(Phys.org) —Air pollution from Asia has been rising for several decades but Hawaii had seemed to escape the ozone pollution that drifts east with the springtime winds. Now a team of researchers has found ...
Earth's core reveals an inner weakness
(Phys.org) —The word "core" conjures up an image of something strong. However, new experiments show that the iron found in the Earth's core is relatively weak. This finding is based on x-ray spectroscopy ...
New research technique shows perennial sea ice cover came about earlier than thought
'Virtual earthquakes' used to forecast Los Angeles quake risk
Stanford scientists are using weak vibrations generated by the Earth's oceans to produce "virtual earthquakes" that can be used to predict the ground movement and shaking hazard to buildings from real quakes.
Electric drive vehicles have little impact on US pollutant emissions, study finds
(Phys.org) —A new study from North Carolina State University indicates that even a sharp increase in the use of electric drive passenger vehicles (EDVs) by 2050 would not significantly reduce emissions of ...
Air pollution tied to exports: Study finds blowback causes extra day per year of ozone smog in LA
Chinese air pollution blowing across the Pacific Ocean is often caused by the manufacturing of goods for export to the U.S. and Europe, according to findings by UC Irvine and other researchers published today ...
Soil production breaks geologic speed record
Geologic time is shorthand for slow-paced. But new measurements from steep mountaintops in New Zealand show that rock can transform into soil more than twice as fast as previously believed possible.
High levels of molecular chlorine found in Arctic atmosphere
(Phys.org) —Scientists studying the atmosphere above Barrow, Alaska, have discovered unprecedented levels of molecular chlorine in the air, a new study reports.
Researchers bulldoze desert to learn how sand dunes form
Land bulge clue to aviation threat from volcanoes
Bulging in land that occurs before a volcano erupts points to how much ash will be spewed into the sky, providing a useful early warning for aviation, geologists in Iceland said on Sunday.
Carbon dioxide study adds to picture of global carbon cycle
(Phys.org) —One of the most widely known compounds on Earth is carbon dioxide, or CO2. We learn as children that CO2 is a key component of photosynthesis, the process by which plants, algae, and bacteria c ...
Study faults a 'runaway' mechanism in intermediate-depth earthquakes
Nearly 25 percent of earthquakes occur more than 50 kilometers below the Earth's surface, when one tectonic plate slides below another, in a region called the lithosphere. Scientists have thought that these ...
Greenland ice stores liquid water year-round
Researchers at the University of Utah have discovered a new aquifer in the Greenland Ice Sheet that holds liquid water all year long in the otherwise perpetually frozen winter landscape. The aquifer is extensive, ...
