    How black soldier fly larvae can demolish a pizza so fast

    It all started with the can’t-tear-your-eyes-away video of black soldier fly larvae devouring a 16-inch pizza in just two hours. Watching sped-up action of the writhing mass inspired mechanical engineer Olga Shishkov of Georgia Tech in Atlanta to see what makes these insects such champions of collective feeding.

    An individual Hermetia illucens larva doesn’t eat steadily, Shishkov found....

    How worm blobs behave like a liquid and a solid

    TAMPA, Fla. — Blobs of worms flow like a fluid, plop like a solid and fascinate scientists.

    A worm by itself is as solid as any other living animal. But a mass of aquatic California blackworms tangled together flows through a tube like a liquid. Pouring, heating and otherwise playing with blobs of worms shows that a tangled mass of them has properties of both fluids and solids, Saad...

    How some sap-sucking insects fling their pee

    Some sap-sucking insects can “make it rain,” flinging droplets of pee while feeding on plant juices. Now scientists have explained how the insects, known as sharpshooters, create these sprays using tiny catapult-like structures that propel the waste at extreme accelerations.

    A tree infested with sharpshooters exudes a steady pitter-patter of pee. “It’s crazy just to look at,” says...

    Zapping substances with electrons can quickly map chemical structures

    The one-hour photo booth has met its molecular match.

    By adapting a technique for determining protein structures, two independent teams have charted chemical structures of antibiotics, hormones and other compounds with unprecedented speed. Depending on the molecule, it took between 30 minutes and a day to determine structures, where traditional techniques could take months to years.

    T. rex pulverized bones with an incredible amount of force

    ALBUQUERQUE — Tyrannosaurus rex had a special way of crunching bones.

    A lethal combination of a powerful bite, strong teeth and repeated crunching allowed these giant predators to pulverize the bones of their prey, researchers reported October 20 at the Society for Vertebrate Paleontology’s annual meeting.

    Bones have a nutritious inner cavity containing marrow and phosphate salts....

    Dandelion seeds create a bizarre whirlpool in the air to fly

    When you’re essentially a little ball of floof, flying is hard.

    To ride the wind, dandelion seeds stir up a weird type of whirlpool in the air directly above them. The newly discovered way of moving through the air, described October 17 in Nature, resolves a long-standing question about how the seeds stay aloft.

    Dandelion seed flight is not unlike the flight of Mary Poppins:...

    How nectar bats fly nowhere

    Flying forward is hard enough, but flying nowhere, just hovering, is so much harder. Most bats and birds can manage the feat for only a few frantic seconds.

    Hovering means losing a useful aerodynamic shortcut, says aerospace engineer and biologist David Lentink of Stanford University. As a bat or bird flies forward, its body movement sends air flowing around the wings and providing some...

    How math helps explain the delicate patterns of dragonfly wings

    The dainty veins gracing the wings of dragonflies and other insects are like fingerprints: Each wing displays a distinct pattern. A randomized mathematical process may help explain how certain thin filaments, called secondary veins, form these complex patterns, a new study finds.

    Insect wings consist of two types of veins, both of which provide structural support (SN: 6/24/17, p. 5)....

    Smart plants can teach us a thing or two

    The Revolutionary Genius of PlantsStefano MancusoAtria Books, $30

    More than 200 years ago, French botanist René Desfontaines instructed a student to monitor the behavior of Mimosa pudica plants as he drove them around Paris in a carriage. Mimosa pudica quickly closes its leaves when touched — presumably as a defense mechanism. Desfontaines was interested in the plants’ response to...

    Here’s how clumps of honeybees may survive blowing in the wind

    A stiff breeze is no match for a clump of honeybees, and now scientists are beginning to understand why.

    When scouting out a new home, the bees tend to cluster together on tree branches or other surfaces, forming large, hanging clumps which help keep the insects safe from the elements. To keep the clump together, individual honeybees change their positions, fine-tuning the cluster’s...
