  1. An image showing multiple galaxies and stars in deep space. An inset closeup shows the supernova Refsdal as a bright smudge
    Astronomy

    A reappearing supernova offers a new measure of the universe’s expansion

    Supernova Refsdal blew up once but burst into view at least five times. The timing of its appearances provides clues to how fast the universe is growing.

  2. An image of the inner Fomalhaut disk.
    Astronomy

    The James Webb telescope revealed surprise asteroids in the Fomalhaut star system

    New images of Fomalhaut confirm that an alleged planet is probably just dust while also revealing a new asteroid belt and a “Great Dust Cloud.”

  3. An illustration of a giant orange star eating a much smaller red planet and a giant burst of bright white dust expanding outward from the tiny planet.
    Astronomy

    For the first time, astrophysicists have caught a star eating a planet

    A burst of light and a cloud of dust are signs that a star 12,000 light-years away swallowed a planet up to 10 times the mass of Jupiter.

  4. A microscopic image of columns of black particles. The top row has gold dots in the center
    Physics

    Videos of gold nanoparticles snapping together show how some crystals grow

    Real-time electron microscopy shows gold nanoparticles tumbling and sliding in a fluid before snapping together in crystalline structures.

  5. A photo from the ATLAS experiment at CERN's Large Hadron Collider.
    Physics

    The W boson might not be heavier than expected after all

    A new and improved look at the mass of the W boson is in close alignment with theory, but it doesn’t negate an earlier, controversial measurement.

  6. An overhead photo of blotchy vegetation taking up the entire frame.
    Math

    Chia seedlings verify Alan Turing’s ideas about patterns in nature

    New experiments confirm that complex patterns in plants emerge from a model proposed by mathematician Alan Turing.

  7. A black and white image of a fruit surrounded by white lines that show the leaps of roundworms.
    Physics

    Static electricity helps parasitic nematodes glom onto victims

    The small electric charge generated by a moving insect is enough to affect the trajectory of a parasitic nematode’s leap so it lands right on its host.

  8. An up close image of two diamond anvils.
    Physics

    Is this the superconductor of scientists’ dreams? A new claim faces scrutiny

    It’s big, if true: transmitting electricity with no resistance at room temperature and moderate pressure. But controversy dogs the team making the claim.

  9. A blue spiral that coalesces into a white ball of light against a black background
    Physics

    Physicists stored data in quantum holograms made of twisted light

    Light that travels in corkscrew-like paths provides a way to make holograms that store large amounts of data in ultrasecure packages.

  10. A photo of the Xi'an fortress wall with the city skyline visible in the background.
    Physics

    Muon scanning hints at mysteries within an ancient Chinese wall

    Density fluctuations within the ancient rampart encircling the city of Xi’an could be defects or yet-to-be-discovered archaeological finds.

  11. An illustration of the Kepler-35 system with a planet in the foreground and two stars in the background.
    Astronomy

    Lots of Tatooine-like planets around binary stars may be habitable

    A new simulation suggests that planets orbiting a pair of stars may be plentiful, and many of those worlds could be suitable for life.

    Materials Science

    Want a ‘Shrinky Dinks’ approach to nano-sized devices? Try hydrogels

    Patterning hydrogels with a laser and then shrinking them down with chemicals offers a way to make nanoscopic structures out of many materials.
