    How Hurricane Maria’s heavy rains devastated Puerto Rico’s forests

    Wind may be the usual suspect for knocking down trees during hurricanes, but a new survey of forest damage in Puerto Rico after back-to-back hurricanes in 2017 highlights the power of a strong downpour. When Hurricane Irma passed off the coast of Puerto Rico on September 6, 2017, the storm brought heavy rains but minimal […] More

    How slime mold helped scientists map out the cosmic web

    Creeping tendrils of slime seem to mirror the structure of the universe’s enormous filaments. That superficial similarity, in an organism called a slime mold, helped scientists map out the cosmic web, the vast threads of matter that connect galaxies. Made up of gas and the unidentified substance called dark matter, the cosmic web began forming […] More

    Economic costs of rising seas will be steeper than we thought, unless we prepare

    Rising seas that swamp cities and coastal infrastructure could cost the world more than 4 percent of the global economy each year by 2100 — far more than previously estimated — unless urgent action is taken both to reduce greenhouse gas emissions and to prepare for such impacts from climate change, a new study finds.  […] More

    Fossil fuel use may emit 40 percent more methane than we thought

    Using fossil fuels releases much more of the potent greenhouse gas methane than previously thought — possibly 25 to 40 percent more, new research suggests. The finding could help scientists and policy makers target how and where to reduce these climate-warming emissions, researchers report February 19 in Nature. The amount of methane released from geologic […] More

    Turning human bodies into compost works, a small trial suggests

    SEATTLE — Human bodies make great worm food. That’s the conclusion of pilot experiments with six dead bodies that were allowed to decompose among wood chips and other organic material. The results, presented February 16 at the annual meeting of the American Association for the Advancement of Science, suggest that composting, also called natural organic […] More

    50 years ago, protests and promises launched the Trans-Alaska Pipeline

    Getting set for a black gold rush, Science News, February 14, 1970 — Nobody has ever done what the engineers designing the Trans-Alaska Pipeline are faced with: the need to carry hot oil through the Arctic. The Trans-Alaska Pipeline, expected to be completed in 1972, will carry 600,000 barrels of oil a day across Alaska. […] More

    The Deepwater Horizon oil spill spread much farther than once thought

    Nearly a decade after the Deepwater Horizon oil spill in the Gulf of Mexico, computer simulations suggest that the toxic pollution extended much farther than satellite images first indicated.   Those images, taken after the spill dumped nearly 800 million liters of oil into Gulf waters, helped to determine which areas would be temporarily closed […] More

    Scientists entangled quantum memories linked over long distances

    Physicists’ fantasies of a future quantum internet are a bit closer to reality. Scientists entangled two quantum “hard drives” that were linked by fibers tens of kilometers long. Entanglement, a type of ethereal quantum connection, allows two particles to behave as if intertwined even when distantly separated. The new study entangled two devices called quantum […] More
