    Nature-inspired camouflage changes its looks with light

    Thin, flexible new material steals the color-shifting capabilities of cephalopod skin.

  3. Life

    Gut bacteria may prevent food allergies

    In mice, gut bacteria blocked food from seeping out of the intestines and triggering an immune reaction in the bloodstream.

  4. Neuroscience

    Laser light rewrites memories in mice

    Mouse experiment demonstrates that good memories can be transformed into bad ones, and vice versa.

  5. Health & Medicine

    To grow new knee cartilage, look to the nose

    Cartilage-making cells from the nose grew into patches that successfully replaced damaged or missing cartilage in the knees of goats and of humans.

  6. Anthropology

    Siberians came to North American Arctic in two waves

    Siberian ancestors of the modern-day Inuit replaced a 4,000-year-old North American Arctic culture, a DNA study reveals.

  7. Neuroscience

    Pulses to the brain bring memory gains

    The ability to associate faces with words is boosted when an outer part of the brain is stimulated, a study shows.

    The Milky Way galaxy lives on the outer edge of a newly discovered supercluster of galaxies named Laniakea that is 520 million light-years across.

  12. Animals

    Archerfish mouth is the secret of precision spit

    Trained fish shoot down two hypotheses for their fine spit control but reveal fancy mouth work.

  13. Oceans

    Plastic may take unexpected routes to marine garbage patches

    By redefining ocean boundaries, researchers offer new insight to how litter moves through the oceans and who’s to blame for the floating clumps of trash.
