  1. raindrops on a car window
    Physics

    Physicists explain the mesmerizing movements of raindrops on car windshields

    Wind and gravity compete to make some raindrops go up while others slide down, a mathematical analysis suggests.

  2. coronal loops, strands of plasma looping around the sun
    Astronomy

    Some of the sun’s iconic coronal loops may be illusions

    Folds in the plasma that streams from the sun might trick the eye into seeing the well-defined arches, computer simulations of the solar atmosphere show.

    Tech

    50 years ago, the future of solar energy looked bright

    In the 1970s, scientists and engineers were coming around to the idea of “farming” the sun’s energy on a large scale.

    The mysterious Hiawatha crater in Greenland is 58 million years old

    An impact crater spotted in 2015 in Greenland is far too old to be connected to the Younger Dryas cold snap from 13,000 years ago, a study suggests.

  6. cephalopod fossil
    Paleontology

    Scientists are arguing over the identity of a fossilized 10-armed creature

    An ancient cephalopod fossil may be the oldest ancestor of octopuses, but the interpretation hinges on the identification of one feature.

    Health & Medicine

    A gene therapy for hemophilia boosts levels of a crucial clotting protein

    A one-time, gene-based treatment for hemophilia increased the amount of a necessary blood clotting protein in men with a severe form of the disease.
