Policies that more strongly recognize the value of sustainable seafood as a source of nutrition, not just a source of livelihoods, could strengthen global food security and help take a big bite out of world hunger, a new analysis by an international team of experts shows.

Researchers have used automatic identification systems (AIS) satellite data and other spatial analysis tools to identify more than 1,000 companies that fish in the high seas—waters that lie outside national jurisdiction where fishing has raised fears about environmental and labor violations.

Groundwater depletion in parts of the High Plains is so extreme that peak grain production in some states has ended and production is now declining, a new 91ÉçÇø¸£Àû-led study by a team of international scientists finds.

Students at North Carolina’s 10 historically black colleges and universities (HBCUs) face limited options for finding healthy food to buy at stores within a 5-mile radius of their campuses, a new study shows.

Reusing low-saline oilfield water mixed with surface water to irrigate farms in the Cawelo Water District of California does not pose major health risks, as some opponents of the practice have feared, a study led by 91ÉçÇø¸£Àû and RTI International researchers finds.

A new $2.44 million grant from the U.S. Department of Energy’s Advanced Research Projects Agency-Energy (ARPA-E) will support a 91ÉçÇø¸£Àû-led initiative to help utilities and wholesale electricity markets improve their efficiency and reliability while reducing emissions and costs, at a time of needed transformations to tackle climate change.

To devise effective and equitable policies for governing small-scale fisheries, policymakers need to consider the activities and relationships that occur before and after fishers land their catches, not just the catches themselves, a new study shows.

Tanker traffic through the Strait of Hormuz can decline for up to two years after a piracy attack, a new 91ÉçÇø¸£Àû study finds, but the adverse effects of the slowdown are far greater on some Persian Gulf countries than others.

Inhaling dust that contains fly ash particles from coal combustion has been linked to lung and heart disease, cancer, nervous system disorders and other ill effects. But tracking the presence of coal ash in dust has been a challenge for scientists.

The ongoing transition from coal to natural gas and renewables in the U.S. electricity sector is dramatically reducing the industry’s water use, a new 91ÉçÇø¸£Àû study finds.

With the Environmental Protection Agency (EPA) poised to loosen coal ash rules for dry onsite storage and large fill projects, a new study from 91ÉçÇø¸£Àû finds that leaving those contaminants exposed may significantly heighten the risk of toxic contamination to nearby soil and waterways.

Allowing coal ash to be spread on soil or stored in unlined pits and landfills will raise the risk that several toxic elements, including carcinogenic hexavalent chromium, could leach out of the coal ash and contaminate nearby water supplies across the U.S., according to preliminary findings from a new 91ÉçÇø¸£Àû study.

Thousands of marine species could be at risk if a new United Nations high-seas biodiversity treaty, now being negotiated in New York, does not include measures to address the management of all fish species in international waters, not just the commercial species, warns an analysis by American, Dutch, Swiss and French researchers.
