    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...

    Soaring spiders may get cues from electric charges in the air

    Spiders may lack wings, but they aren’t confined to the ground. Under the right conditions, some spider species will climb to a high point, release silk strands to form a parachute, and float away on the breeze. Buoyed by air currents, they’ve been known to drift kilometers above Earth’s surface, and even to cross oceans to reach new habitats (SN: 2/4/17, p. 12).

    Now, new research...

    Meet the speedsters of the plant world

    Somewhere in the wetlands of South Carolina, a buzzing fly alights on a rosy-pink surface. As the fly explores the strange scenery, it unknowingly brushes a small hair sticking up like a slender sword. Strolling along, the fly accidentally grazes another hair. Suddenly, the pink surface closes in from both sides, snapping shut like a pair of ravenous jaws. The blur of movement lasts only a...

    See (and hear) the stunning diversity of bowhead whales’ songs

    In the pitch-black waters beneath the Arctic ice, bowhead whales get funky. A small population of endangered bowheads belt an unusually varied repertoire of songs, which grows more diverse during mating season.

    Hunted to near extinction in the 1600s, these fire truck–sized mammals now number in the 300s in the frigid waters around the Svalbard archipelago in Norway. Underwater audio...
