  1. blurry illustration of the exoplanet Wasp-39 b with its star in the background

    The James Webb telescope spotted CO2 in an exoplanet’s atmosphere

    The first definitive detection of the gas on a world in another solar system paves the way for detections in planets that are more Earthlike.

  2. an ecologist releases a hawkmoth at dusk

    How death’s-head hawkmoths manage to fly straight for miles in the dark

    By tailing death’s-head hawkmoths in an airplane, scientists have found that the nocturnal insects appear to navigate using an internal compass.

  3. NASA’s Space Launch System rocket and the Orion spacecraft preparing to launch against a hazy sky

    NASA’s Artemis I mission sets the stage for our return to the moon

    The launch, scheduled for August 29, will test many aspects of the rocket, capsule and spacesuits that will take astronauts back to the moon.

  4. photo of a levitating force sensor in gold amid red-hued light

    ‘Chameleon’ forces remain elusive in a new dark energy experiment

    A hypothetical fifth force associated with “chameleon” dark energy and that morphs based on its environment didn’t turn up in a sensitive experiment.

  5. mealworms on a table, in a wooden spoon, and in a wooden bowl, surrounded by green leaves
    Science & Society

    A new seasoning smells like meat thanks to sugar — and mealworms

    A spoonful of sugars could help cooked mealworms go down more easily, a potential boon for the planet.

  6. 3-D models of an upper leg bone and two forearm bones, each shown from two angles

    7-million-year-old limb fossils may be from the earliest known hominid

    An earlier report on one of the bones of a 7-million-year-old creature that may have walked upright has triggered scientific misconduct charges.

  7. Yeast DNA transcription

    50 years ago, genes eluded electron microscopes

    In the 1970s, scientists dreamed of seeing genes under the microscope. Fifty years later, powerful new tools are helping to make that dream come true.

    Sleep deprivation may make people less generous

    Helping each other is inherently human. Yet new research shows that sleep deprivation may dampen people’s desire to donate money.

  9. Illustration of Kuiper Belt in the solar system

    The discovery of the Kuiper Belt revamped our view of the solar system

    Thirty years ago, astronomers found the Kuiper Belt, a region of space home to Pluto and other icy worlds that helped show how the solar system evolved.

  10. a close-up photo of a jumping spider

    News stories have caught spiders in a web of misinformation

    Nearly half of news stories about peoples’ interactions with spiders contain errors, according to a new analysis.

  11. An illustration of a huge asteroid crashing into ocean. An ancient sea creature is visible under the water

    Not one, but two asteroids might have slain the dinosaurs

    A craterlike structure found off West Africa’s coast might have been formed by an asteroid impact around the same time the dinosaurs went extinct.

  12. A scanning electron microscope image of a sea urchin skeleton, showing many honeycomb-like holes

    Sea urchin skeletons’ splendid patterns may strengthen their structure

    “Voronoi” geometric patterns found in sea urchin skeletons yield strong yet lightweight structures that could inspire the creation of new materials.
