  • Pulse of the polar vortex revealed: A key to mapping future storms
    on July 10, 2018 at 3:01 pm

    If you can predict the path of the jet stream, the upper atmosphere's undulating river of wind, then you can predict weather -- not just for a week or two, but for an entire season. A new study moves toward that level of foresight by revealing a physical link between the speed and location of the jet stream and the strength of the polar vortex, a swirl of air that usually hovers over the Arctic. […]

  • Stripes may be cool -- but they don't cool zebras down
    on July 6, 2018 at 2:03 pm

  • Spiders go ballooning on electric fields
    on July 5, 2018 at 3:40 pm

    The aerodynamic capabilities of spiders have intrigued scientists for hundreds of years. Scientists have attributed the flying behavior of these wingless arthropods to 'ballooning', where spiders can be carried thousands of miles by releasing trails of silk that propel them up and out on the wind. However, the fact that ballooning has been observed when there is no wind to speak of, when skies are overcast and even in rainy conditions, raises the question: how do spiders take off with low levels of aerodynamic drag? […]

  • Oxygen loss in the coastal Baltic Sea is 'unprecedentedly severe'
    on July 5, 2018 at 12:42 pm

    The Baltic Sea is home to some of the world's largest dead zones, areas of oxygen-starved waters where most marine animals can't survive. But while parts of this sea have long suffered from low oxygen levels, a new study shows that oxygen loss in coastal areas over the past century is unprecedented in the last 1,500 years. […]
