In a new study, researchers confirm a theory from the 1970s that coastal hunter-gatherers processed much of their shellfish at the beach before returning with their meat to camps on higher ground, leaving the heavy shells by the water. This finding has dramatic implications for past analyses of hunter-gatherer diets -- because many beachside shell middens would now be destroyed or underwater due to past sea level rises since the last Ice Age.
Vocal control areas in the brain of weaver birds fire in time when they sing together.
NEW YORK - Even as the U.S. Environmental Protection Agency (EPA) continues dedicated efforts to help Puerto Rico and the U.S. Virgin Islands recover from 2017 Hurricanes Irma and Maria, EPA is keenly aware of and sensitive to community needs.
Governments have a wide variety of policy options at their disposal to respond to the growing threat of antimicrobial resistance, but many of these approaches have not been rigorously evaluated, according to a new study.
Overdose from opiates has skyrocketed. According to the National Center for Health Statistics, on average, 130 Americans die every day from an opioid overdose. The high cost of antidotes such as NARCAN® prevents many first responders from having access to lifesaving antidotes when they need it most. Researchers have identified a new method of producing these compounds using a microorganism discovered in a waste stream associated with processing of opium poppy.
Scientists have identified specific parts of genetic code within switchgrass that could contribute to larger switchgrass harvests while reducing potential crop weaknesses.
One anomaly in the North Pacific Subtropical Gyre ecosystem that has puzzled oceanographers for years: The region's chemistry changes periodically, affecting the overall nutrient composition and its biological productivity. In a new study, researchers document what induces these variations: changes in the amount of iron that is deposited into the ocean via dust from Asia.
Researchers have announced the groundbreaking findings of a two-year study of the plasmonic properties of daguerreotypes.
Preliminary results from a new study suggest that sleep disturbances are associated with mental health problems among survivors of a natural disaster even two years after the event.
