    Unlocking the secrets of a plastic-eater

    It was during a cruise in Alaska that Linda Zhong realized that the world didn’t have to be full of plastic. “I grew up in cities, so you’re very used to seeing all kinds of trash everywhere,” says the graduate student in microbiology. Zhong, who is Canadian and lived in Ottawa growing up and in […] More

    Peatland drainage in Southeast Asia adds to climate change

    In less than three decades, most of Southeast Asia’s peatlands have been wholly or partially deforested, drained, and dried out. This has released carbon that accumulated over thousands of years from dead plant matter, and has led to rampant wildfires that spew air pollution and greenhouse gases into the atmosphere. The startling prevalence of such […] More

    Study: Reflecting sunlight to cool the planet will cause other global changes

    How can the world combat the continued rise in global temperatures? How about shading the Earth from a portion of the sun’s heat by injecting the stratosphere with reflective aerosols? After all, volcanoes do essentially the same thing, albeit in short, dramatic bursts: When a Vesuvius erupts, it blasts fine ash into the atmosphere, where […] More

    Machine learning helps map global ocean communities

    On land, it’s fairly obvious where one ecological region ends and another begins, for instance at the boundary between a desert and savanna. In the ocean, much of life is microscopic and far more mobile, making it challenging for scientists to map the boundaries between ecologically distinct marine regions. One way scientists delineate marine communities […] More

    Melting glaciers cool the Southern Ocean

    Tucked away at the very bottom of the globe surrounding Antarctica, the Southern Ocean has never been easy to study. Its challenging conditions have placed it out of reach to all but the most intrepid explorers. For climate modelers, however, the surface waters of the Southern Ocean provide a different kind of challenge: It doesn’t […] More
