  2. A snapshot of a collapsing star spewing jets, colored red and green, outward against the backdrop of space
    Astronomy

    A simulation of a dying star shows how it could create gravitational waves

    Massive jets and an expanding cocoon of debris from a collapsing star could be a source of never-before-seen ripples in spacetime.

  3. A satellite image of Hurricane Ian with its eye just west of Florida
    Climate

    Why the 2023 Atlantic hurricane season is especially hard to predict

    It’s hard to know how busy this year’s Atlantic hurricane season will be, thanks to a rarely observed combination of ocean and climate conditions.

  4. A shape called a spectre covers an infinite plane with some of them a light green connected to a dark green scattered amongst white spectres.
    Math

    A ‘vampire einstein’ tile outdoes mathematicians’ latest feat

    A newfound shape covers an infinite plane with a pattern that doesn’t repeat and without mirror images of the shape.

  7. A photo of a wooden walkway leading between several gray and white boxes in a large grassy field.
    Life

    Air pollution monitoring may accidentally help scientists track biodiversity

    Filters in air monitoring facilities inadvertently capture environmental DNA, which could give scientists a new tool to track local plants and animals.

    Health & Medicine

    Taurine slows aging in mice. Will it ever work for people?

    The amino acid taurine — found in meats, produced by the body and common in energy drinks — may have a role in health and aging, a new study suggests.

  9. Two scuba divers investigating a coral reef
    Life

    Coral reefs host millions of bacteria, revealing Earth’s hidden biodiversity

    A new estimate of microbial life living in Pacific reefs is similar to global counts, suggesting many more microbes call Earth home than thought.

  10. Three images of a cyclone at the north pole of Uranus are seen in different wavelengths. The image on the left shows the cyclone in a white color, the middle cyclone a green color and the cyclone on the right is an orange color.
    Space

    A cyclone has been spotted swirling over Uranus’ north pole for the first time

    Voyager 2 hinted at a cyclone at Uranus’ south pole. Now Earth-based observations give the first direct evidence of a storm at the ice giant’s north pole.

  11. A false-color image of a watery plume coming off Saturn's moon Enceladus.
    Planetary Science

    JWST captured Enceladus’ plume spraying water nearly 10,000 kilometers into space

    NASA’s James Webb Space Telescope reveals the rate at which Saturn’s moon Enceladus spews water and where that water ends up.

    Animals

    These ants build tall nest hills to help show the way home

    Desert ants living in the harsh, flat salt pans of Tunisia create towering anthills to aid with navigating the near-featureless terrain.

    Health & Medicine

    50 years ago, scientists thought coffee might treat hyperactivity

    Decades of follow-up research into whether caffeine can treat the symptoms of kids with ADHD has come up with more questions than answers.

  14. An ancient toilet that looks like a square stone block with a circular hole in the middle
    Humans

    Oldest traces of a dysentery-causing parasite were found in ancient toilets

    Scientists have found traces of giardia in two toilets used by wealthy residents of Jerusalem in the 7th and 6th century B.C.
