A new international analysis of marine fossils shows that warming of the polar oceans during the Eocene, a greenhouse period that provides a glimpse of Earth's potential future climate, was greater than previously thought.
University of Washington researchers have published the first major assessment of small hydropower dams around the world -- including their potential for growth -- and highlight the incredibly variability in how dams of varying sizes are categorized, regulated and studied.
It has long been recognized that the Inka incorporated diverse peoples into their empire, but how these ethnic groups developed historically during the political upheaval of the preceding Late Intermediate Period (LIP; AD 1100-1450) is only now receiving commensurate attention.
Marine plants and seaweeds in shallow coastal ecosystems can play a key role in alleviating the effects of ocean acidification, and their robust population in shoreline environments could help preserve declining shellfish life, according to a study by University of California, Irvine ecologists.
A new battery technology developed at MIT, based on a metal-mesh membrane and electrodes made of molten sodium, could open the way for more intermittent, renewable power sources on the grid.
A team led by the Department of Energy's Oak Ridge National Laboratory has uncovered how certain soil microbes cope in a phosphorus-poor environment to survive in a tropical ecosystem. Their novel approach could be applied in other ecosystems to study various nutrient limitations and inform agriculture and terrestrial biosphere modeling.
Researchers at The Ohio State University and their colleagues have demonstrated how two separate effects of climate change combine to destabilize different populations of coral microbes -- that is, unbalance the natural coral 'microbiome.'
Every summer, the Gulf of Mexico is flooded with excess nitrogen and phosphorus from wastewater treatment plants and farm fields along the Mississippi River basin. And every summer, those nutrients create a 'dead zone' in the Gulf. To address the issue, the US Environmental Protection Agency formed a task force and required 12 states to develop strategies to reduce agricultural runoff.
Research led by The University of Texas at Austin has found that calculations of water storage in many river basins from commonly used global computer models differ markedly from independent storage estimates from GRACE satellites.
Researchers at Swansea University's Complex Flow Lab have been exploring the intricate shapes that emerge when air is injected into soil. Published in Physical Review Applied, these findings could one day be used to speed up the decontamination of industrial brownfield sites?which the United Kingdom currently has over 400,000 hectares of.
