While a warming climate in recent decades may be a factor in the waning of some local populations of frogs, toads, newts and salamanders, it cannot explain the overall steep decline of amphibians, according to researchers.
New research for the first time reveals the three-dimensional structure of a membrane channel that's critical in controlling blood pressure. The findings, published today in the open-access journal eLife, represent the first time the human epithelial sodium channel has been shown so precisely since it was first isolated and described through expression cloning more than two decades ago.
NASA's Aqua satellite passed over the Central North Atlantic Ocean and analyzed Subtropical Storm Leslie in infrared light to determine what was happening within.
A new study found a dramatic increase in the chemical weathering rates of mined landscapes, which are melting away bedrock up to 45 times faster than unmined areas. The weathering has global consequences for the cycling of sulfur, a key nutrient for all life forms.
The seasonal filling and emptying of reservoirs in India can cause measurable deformation of the surrounding rock, reducing the strength of nearby faults and potentially triggering earthquakes, according to two new papers published in the Bulletin of the Seismological Society of America.
A unique combination of imaging tools and atomic-level simulations has allowed a team led by the Department of Energy's Oak Ridge National Laboratory to solve a longstanding debate about the properties of a promising material that can harvest energy from light.
A new technique to increase the efficiency of carbon dioxide (CO2) electrolysis that may lead to the production of new chemicals and fuels.
NASA provided an infrared look at newly developed Tropical Storm Rosa in the Eastern Pacific and found the storm was getting better organized.
New research finds that 500 years of over-exploitation has halved mammal populations in South America's once majestic Atlantic Forest. A new analysis of mammal populations reveals the devastating effects of human disturbance since the area was first colonised in the 1500s. They found that apex predators and large carnivores, such as jaguars and pumas, as well as large-bodied herbivores, such as tapirs, were among the groups whose numbers had suffered the most.
More than 26,000 years ago, sea level was much lower than it is today partly because the ice sheets that jut out from the continent of Antarctica were enormous and covered by grounded ice -- ice that was fully attached to the seafloor. As the planet warmed, the ice sheets melted and contracted, and sea level began to rise. LSU Department of Geology & Geophysics Associate Professor Phil Bart and his students have discovered new information that illuminates how and when this global phenomenon occurred.
