    A study of Earth’s crust hints that supernovas aren’t gold mines

    Supernovas aren’t the main source of gold, silver and other heavy elements, a study of deep-sea crust suggests.

    Morphing noodles start flat but bend into curly pasta shapes as they’re cooked

    Shape-shifting pasta could potentially cut down on packaging and save space during shipping.

    Physics

    A clock’s accuracy may be tied to the entropy it creates

    A clock made from a thin, wiggling membrane releases more entropy, or disorder, as it becomes more accurate.

    The thickness of lead’s neutron ‘skin’ has been precisely measured

    At 0.28 trillionths of a millimeter thick, the shell of neutrons around the nucleus of an atom of lead is a bit thicker than physicists had predicted.

    Stars made of antimatter could lurk in the Milky Way

    Fourteen celestial sources of gamma rays provide preliminary hints of matter colliding with “antistars” in our galaxy.

    X-ray scans explain how the ‘Brazil nut effect’ works

    X-ray CT scans of a box of mixed nuts explain the orientations that let large, oblong Brazil nuts rise to the top.

    The already tiny neutrino’s maximum possible mass has shrunk even further

    At less than an electron volt, neutrinos are by far the most lightweight massive particles known, a new measurement confirms.

    Neutron stars may not be as squishy as some scientists thought

    NASA’s NICER X-ray telescope finds that the most massive known neutron star has an unexpectedly large diameter.
