  1. A photo looking into a drill hole in West Antarctica. White ice is seen on the edges of the frame which turns into a gradient of light blue to dark blue in the center circle of the image.

    In one lake deep under Antarctica’s ice, microbes feast on ancient carbon

    Microorganisms living in a lake beneath the ice sheet in West Antarctica feed on ocean carbon that was deposited 6,000 years ago.

  2. A shiver of scalloped hammerhead sharks swim near the surface, in this underwater photograph. These endotherms may thermoregulate by closing their gills as they go deeper.

    Why some hammerhead sharks seem to ‘hold their breath’ during dives

    Scalloped hammerhead sharks in Hawaii seem to limit the use of their gills during deep dives to prevent losing heat to their surroundings.

  3. A photo of a bat flying over top a body of water and dipping its mouth in.

    Pregnancy may hamper bats’ ability to ‘see’ in the dark

    Tiny Kuhl’s pipistrelle bats make fewer calls when pregnant, which may make it more difficult to hunt prey, lab tests hint.

  4. A close up photo of several red flour beetles sitting on a pile of white flour with specks of flour stuck to some of the beetles.

    How some beetles ‘drink’ water using their butts

    Red flour beetles, a major agricultural pest, suck water out of the air using special cells in their rear ends, a new study suggests.

  5. image of a circular lock of Beethoven's hair attached to an old piece of paper with something written in cursive script

    DNA from Beethoven’s hair hints at what killed the composer

    Many historians suspect Beethoven died from liver failure. A new analysis shows he had a heightened genetic risk for liver disease, researchers say.

    A hormone shot helped drunk mice sober up quickly

    Drunk mice injected with the hormone FGF21 woke up and regained their balance faster than inebriated mice that did not receive the shot.

  7. fungi growing on wood

    Chemical signals from fungi tell bark beetles which trees to infest

    As fungi break down defensive chemicals in trees, some byproducts act as signals to bark beetle pests, telling them which trees are most vulnerable.

  8. An orange and gray Australian painted lady sitting atop a bright magenta flower.

    76 percent of well-known insects fall outside protected areas

    Protected areas can provide safe havens for insects, but many existing ones fall short, a new study finds.

  9. A wide photo of a valley on Ellesmere Island in Canada with mountains in the background.

    Fossils suggest early primates lived in a once-swampy Arctic

    Teeth and jawbones found on Ellesmere Island, Canada, suggest that two early primate species migrated there 52 million years ago.

  10. An Amazonian woman walks away from the camera while holding a large basket on her head.

    Indigenous people may have created the Amazon’s ‘dark earth’ on purpose

    Modern Amazonians make nutrient-rich soil from ash, food scraps and burns. The soil strongly resembles ancient dark soils found in the region.

  11. A woman wearing a face mask stands inside a home, looking out through a window

    Brain scans suggest the pandemic prematurely aged teens’ brains

    A small study suggests that the COVID-19 pandemic may have aged teen brains beyond their years.

  12. A photo of spider monkey bones found buried alongside eagle bones to the left and other animal bones

    A spider monkey’s remains tell a story of ancient diplomacy in the Americas

    A 1,700-year-old spider monkey skeleton unearthed at Teotihuacan in Mexico was likely a diplomatic gift from the Maya.
