Gainesville, Fla.— A team of U.S. Geological Survey (USGS) and academic scientists are analyzing samples of coral and surrounding sediments from an area damaged near the Deepwater Horizon site in the Gulf of Mexico. (more…)
*Ordinary drinking glasses and atmospheric dust particles break apart in similar patterns*
Clues to future climate may be found in the way an ordinary drinking glass shatters.
Results of a study published this week in the journal Proceedings of the National Academy of Sciences find that microscopic particles of dust can break apart in patterns that are similar to the fragment patterns of broken glass and other brittle objects. (more…)
*New results indicate potential to reduce certain greenhouse gas emissions from oceans to atmosphere*
Increasing acidity in the sea’s waters may fundamentally change how nitrogen is cycled in them, say marine scientists who published their findings in this week’s issue of the journal Proceedings of the National Academy of Sciences (PNAS).
Nitrogen is one of the most important nutrients in the oceans. All organisms, from tiny microbes to blue whales, use nitrogen to make proteins and other important compounds. (more…)
ANN ARBOR, Mich.— The right material wrapped around your car’s exhaust system could one day scavenge heat that would otherwise be wasted, turning it into energy to warm the cabin or recharge the battery. (more…)
*Waterways receiving nitrogen from human activities are significant source*
What goes in must come out, a truism that now may be applied to global river networks.
Human-caused nitrogen loading to river networks is a potentially important source of nitrous oxide emission to the atmosphere. Nitrous oxide is a potent greenhouse gas that contributes to climate change and stratospheric ozone destruction. (more…)
Wind turbines in Midwestern farm fields may be doing more than churning out electricity. The giant turbine blades that generate renewable energy might also help corn and soybean crops stay cooler and drier, help them fend off fungal infestations and improve their ability to extract growth-enhancing carbon dioxide from the air and soil. (more…)
SAN FRANCISCO — The northernmost mummified forest ever found in Canada is revealing how plants struggled to endure a long-ago global cooling. (more…)
Rising concentrations of zinc in a waterway on Colorado’s Western Slope may be the result of climate change that is affecting the timing of annual snowmelt, says a new study led by the University of Colorado at Boulder. (more…)
