  • New technique offers clues to measure the deoxygenation of the ocean
    on August 9, 2017 at 6:20 pm

    The living, breathing ocean may be slowly starting to suffocate. More than two percent of the ocean's oxygen content has been depleted during the last half century, according to reports, and marine 'dead zones' continue to expand throughout the global ocean. This deoxygenation, triggered mainly by more fertilizers and wastewater flowing into the ocean, pose a serious threat to marine life and ecosystems. […]

  • Humans have been altering tropical forests for at least 45,000 years
    on August 3, 2017 at 1:19 pm

    A new study counters the view that tropical forests were pristine natural environments prior to modern agriculture and industrialization. Moreover, humans have in fact been having a dramatic impact on such forest ecologies for tens of thousands of years, through techniques ranging from controlled burning of sections of forest to plant and animal management to clear-cutting.
