An international team discovers that production of a potent greenhouse gas can be bypassed as soil nitrogen breaks down into unreactive atmospheric N2.
University of California, Irvine glaciologists have uncovered large oceanic valleys beneath some of the massive glaciers flowing into the Amundsen Sea in West Antarctica. Carved by earlier advances of ice during colder periods, the subsurface troughs enable warm, salty water to reach the undersides of glaciers, fueling their increasingly rapid retreat.
Rice University's Baker Institute for Public Policy has released policy recommendations for President-elect Donald Trump's administration, which includes science and health care.
Researchers are reviving one of the Mississippi River's main filters: the floodplain. The result is a unique environment that removes nitrogen, a contributor to the Gulf of Mexico's dead zone.
Glaciologists have uncovered large valleys in the ocean floor beneath some of the massive glaciers flowing into the Amundsen Sea in West Antarctica. Carved by earlier advances of ice during colder periods, the troughs enable warm, salty water to reach the undersides of glaciers, fueling their increasingly rapid retreat.
University of Rochester researchers have found that adults and children in the US, adults from a 'low numeracy' tribe in Bolivia and rhesus monkeys ALL possessed the ability to distinguish between large and small quantities of objects, regardless of the surface area they occupy. This ability is likely a shared evolutionary trait, according to a study published in Nature Communications. The nonverbal visual tests could be used in assessing early math education in young children.
Natural gas production on Pennsylvania's vast black shale deposit known as the Marcellus Shale will nearly double by 2030 to meet growing demand, tripling Pennsylvania's greenhouse gas emissions from the natural gas sector relative to 2012 levels, according to a report published today by Delaware Riverkeeper Network. The increase in greenhouse gas emissions will remain steady through 2045 with continued shale gas development, projects the report, 'Lifecycle Greenhouse Gas Emissions Associated with Projected Future Marcellus Development.'
The transport of heat in amorphous materials is largely determined by the behavior of phonons -- quasiparticles associated with the collective vibrations of atoms. Researchers from Georgia Tech developed a new way to calculate the heat contribution of phonons using computer simulations. Using the Stampede supercomputer at the Texas Advanced Computing Center, they modeled amorphous silicon -- glass -- providing new insights into a material that is critical for energy efficiency.
The daily US economic cost from solar storm-induced electricity blackouts could be in the tens of billions of dollars, with more than half the loss from indirect costs outside the blackout zone, according to a new study.
The world relies heavily on gasoline and other hydrocarbons to power its cars and trucks. In search of an alternative fuel type, some researchers are turning to the stuff of fireworks and explosives: metal powders. And now one team is reporting a method to produce a metal nanopowder fuel with high energy content that is stable in air and doesn't go boom until ignited. Their study appears in the ACS journal Energy & Fuels.
