    Flying insects tell tales of long-distance migrations

    Every autumn, a quiet mountain pass in the Swiss Alps turns into an insect superhighway. For a couple of months, the air thickens as millions of migrating flies, moths and butterflies make their way through a narrow opening in the mountains. For Myles Menz, it’s a front-row seat to one of the greatest movements in the animal kingdom.

    Menz, an ecologist at the University of Bern in...

    Humpback whale bumps have marine biologists stumped

    Off the Kohala coast on the Big Island of Hawaii, Christine Gabriele spots whale 875. The familiar propeller scar on its left side and the shape of its dorsal fin are like a telltale fingerprint. Gabriele, a marine biologist with the Hawaii Marine Mammal Consortium, confirms the whale’s identity against her extensive photo catalog. Both Gabriele and this male humpback have migrated to this...

    How obesity makes it harder to taste

    As mice plumped up on a high-fat diet, some of their taste buds vanished. This disappearing act could explain why some people with obesity seem to have a weakened sense of taste, which may compel them to eat more.

    Compared with siblings that were fed normal mouse chow, mice given high-fat meals lost about 25 percent of their taste buds over eight weeks. Buds went missing because mature...

    It’s official: Termites are just cockroaches with a fancy social life

    Termites are the new cockroach.

    Literally. The Entomological Society of America is updating its master list of insect names to reflect decades of genetic and other evidence that termites belong in the cockroach order, called Blattodea.

    As of February 15, “it’s official ... that termites no longer have their own order,” says Mike Merchant of Texas A&M University in College...

    Look to penguins to track Antarctic changes

    PORTLAND, Ore. — Penguins preserve records of Antarctic environmental change. The birds’ feathers and eggshells contain the chemical fingerprints of variations in diet, food web structure and even climate, researchers reported February 12 at the American Geophysical Union’s 2018 Ocean Sciences Meeting.

    The Antarctic environment has changed dramatically in recent decades. Overfishing has...

    Skyrmions open a door to next-level data storage

    Like sailors and spelunkers, physicists know the power of a sturdy knot.

    Some physicists have tied their hopes for a new generation of data storage to minuscule knotlike structures called skyrmions, which can form in magnetic materials. Incredibly tiny and tough to undo, magnetic skyrmions could help feed humankind’s hunger for ever-smaller electronics.

    On traditional hard drives,...

    When it’s playtime, many kids prefer reality over fantasy

    Young children travel to fantasy worlds every day, packing just imaginations and a toy or two.

    Some preschoolers scurry across ocean floors carrying toy versions of cartoon character SpongeBob SquarePants. Other kids trek to distant universes with miniature replicas of Star Wars robots R2-D2 and C-3PO. Throngs of youngsters fly on broomsticks and cast magic spells with Harry Potter and...

    A peek into polar bears’ lives reveals revved-up metabolisms

    View the video

    Female polar bears prowling springtime sea ice have extreme weight swings, some losing more than 10 percent of their body mass in just over a week. And the beginnings of bear video blogging help explain why.

    An ambitious study of polar bears (Ursus maritimus) in Alaska has found that their overall metabolic rate is 1.6 times greater than thought, says wildlife...

    New laser emits a more stable, energy-efficient light beam

    A new type of laser is modeled after an exotic class of materials called topological insulators. And it’s proving more reliable and energy-efficient than its conventional counterparts, paving the way for possible use in quantum communication and next-generation electronics.

    The device, described online February 1 in Science, is composed of a grid of semiconductor rings that convert...

    Here’s why so many saiga antelope mysteriously died in 2015

    Spring calving season for the saiga antelope of central Kazakhstan is a delight for the researchers who keep tabs on the critically endangered animals. During the day, thousands of newborn saigas lie quiet, hidden within a sea of waving grass. Mothers return twice daily to feed them. “If you come at dawn and dusk, it’s magical,” says E.J. Milner-Gulland, a conservation biologist at the...
