UMD biologist finds alligators build neural maps of sound the way birds do, suggesting the hearing strategy existed in their common ancestor, the dinosaurs.
Splitting water into hydrogen and oxygen presents an alternative to fossil fuels, but purified water is a precious resource. A Stanford-led team has now developed a way to harness seawater -- Earth's most abundant source -- for chemical energy.
One of the things that makes mammals special is our diverse forelimbs -- bat wings, whale flippers, gibbon arms, and cheetah legs have evolved to do different, specialized tasks. Scientists wanted to see where this mammalian trait started evolving, so they examined fossils from early mammal relatives to see when the upper arm bones started diversifying. They discovered that the trait took root 270 million years ago -- 30 million years before the earliest dinosaurs existed.
Visible imagery from NASA's Terra satellite revealed 03W that formed near the island of Yap in the Northwestern Pacific Ocean.
A USDA Forest Service scientist and 29 co-authors completed one of the largest and longest examinations to trace unprocessed nitrate movement in forests. The team found that some nitrate occasionally moves too fast for biological uptake, resulting in 'unprocessed' nitrate bypassing the otherwise effective filter of forest biology.
Tropical Cyclone Savannah continued to move in southerly direction in the Southern Indian Ocean, and move away from Indonesia. NASA-NOAA's Suomi NPP satellite provided a visible image of the storm. Savannah is no threat to land areas.
Visible imagery from NASA's Terra satellite showed Tropical Cyclone continued to move in a westerly direction after making landfall in Mozambique.
An international study co-led by researchers from the Spanish National Research Council (CSIC) at the Institute of Evolutionary Biology (IBE) and Harvard University (USA) has developed a genetic map of the Iberian Peninsula covering the last 8,000 years.
A team of scientists including researchers at the U.S. Department of Energy's Brookhaven National Laboratory and SLAC National Accelerator Laboratory have identified the causes of degradation in a cathode material for lithium-ion batteries, as well as possible remedies. Their findings, published on March 7, 2019, in Advanced Functional Materials, could lead to the development of more affordable and better performing batteries for electric vehicles.
NIMS, the University of Tokyo, Niigata University and RIKEN jointly designed a multilayered metamaterial that realizes ultra-narrowband wavelength-selective thermal emission by combining the machine learning (Bayesian optimization) and thermal emission properties calculations (electromagnetic calculation). The joint team then experimentally fabricated the designed metamaterial and verified the performance. These results may facilitate the development of highly efficient energy devices.
