    Curbing pedestrian stops might not reduce police-civilian encounters

    In Chicago, traffic stops soared as pedestrian stops fell. Single policy changes therefore don’t tell the whole policing story, researchers say.

    New computer analysis hints volcanism killed the dinosaurs, not an asteroid

    Scientists take a creative approach to investigating what caused the mass extinction 66 million years ago, but the debate is far from settled.

    How a deadly fungus is so good at sticking to skin and other surfaces

    One of Candida auris’ scary superpowers is its stick-to-itiveness. Unlike other fungi, the pathogen uses electrical charges to glom onto things.

    Cosmology

    New JWST images suggest our understanding of the cosmos is flawed

    JWST data don’t resolve a disagreement over how fast the universe is expanding, suggesting we might need strange new physics to fix the tension.

  6. An illustration of antimatter falling under the influence of gravity.

    Antimatter falls like matter, upholding Einstein’s theory of gravity

    In a first, scientists dropped antihydrogen atoms and measured how they fell.

    Paleontology

    A one-of-a-kind trilobite fossil hints at what and how these creatures ate

    The preserved contents suggest the trilobite fed almost continuously and had a gut environment with an alkaline or neutral pH, researchers say.

    This ‘polar ring’ galaxy looks like an eye. Others might be hiding in plain sight

    New images of two galaxies reveal what look like rarely seen rings of hydrogen gas nearly perpendicular to the galaxies’ starry disks.

    Seen Bigfoot or the Loch Ness Monster? Data suggest the odds are low

    Floe Foxon is a data scientist by day. But in his free time, he applies his skills to astronomy, cryptology and sightings of mythical creatures.

    Astronomers call for renaming the Magellanic Clouds

    Explorer Ferdinand Magellan is not a fitting namesake for the pair of satellite galaxies of the Milky Way, a group of scientists argues.
