  • Fisheries given a solution to overharvesting
    on November 1, 2017 at 4:24 pm

    Many commercial fisheries are threatened by overharvesting. However, they can't address the problem because of inadequate scientific information, from overall population numbers to data on how fast fish grow and reproduce. Researchers have developed a model using information about landed fish catches and prices for any species. This model allows fisheries to net enough to meet rising demand while ensuring adequate income and replenishment of natural stocks. […]

  • US ocean observation critical to understanding climate change, but lacks long-term national planning
    on October 20, 2017 at 4:57 pm

    Ocean observing systems are important as they provide information essential for monitoring and forecasting changes in Earth's climate on timescales ranging from days to centuries. A new report finds that continuity of ocean observations is vital to gain an accurate understanding of the climate, and calls for a decadal, national plan that is adequately resourced and implemented to ensure critical ocean information is available to understand and predict future changes. […]

  • Eye-catching labels stigmatize many healthy foods
    on October 19, 2017 at 9:16 pm

  • Reducing power plants' freshwater consumption with new silica filter
    on October 18, 2017 at 3:35 pm

    Power plants draw more freshwater than any other consumer in the United States, accounting for more than 50 percent of the nation's freshwater use at about 500 billion gallons daily. To help save this water, researchers have developed a new silica filter for power plant cooling waters that decreases the amount of freshwater power plants consume by increasing the number of times cooling tower water can be reused and recycled. […]

  • Drought: A cause of riots
    on September 26, 2017 at 1:05 pm

    The scientific community has been working on the possibility of a relationship between periods of drought and rioting for several years. Now a team has formally verified this hypothesis by studying almost 1,800 riots that occurred over a 20-year period in sub-Saharan Africa. The researchers observed a systematic link between the sudden depletion of water resources and the outbreak of unrest. They also succeeded in quantifying the impact of geographic and social factors on the same link. […]
