    Ladybugs fold their wings like origami masters

    View the video

    Those who struggle to fit a vacation wardrobe into a carry-on might learn from ladybugs. The flying beetles neatly fold up their wings when they land, stashing the delicate appendages underneath their protective red and black forewings.

    To learn how one species of ladybug (Coccinella septempunctata) achieves such efficient packing, scientists needed to see under the...

    Live antibiotics use bacteria to kill bacteria

    The woman in her 70s was in trouble. What started as a broken leg led to an infection in her hip that hung on for two years and several hospital stays. At a Nevada hospital, doctors gave the woman seven different antibiotics, one after the other. The drugs did little to help her. Lab results showed that none of the 14 antibiotics available at the hospital could fight the infection, caused by...

    New video camera captures 5 trillion frames every second

    View the video

    A new video camera, the fastest by far, has set a staggering speed record. It films 5 trillion frames (equivalent to 5 trillion still images) every second, blowing away the 100,000 frames per second of high-speed commercial cameras. The device could offer a peek at never-before-seen phenomena, such as the blazingly fast chemical reactions that drive explosions or...

    New dinosaur resurrects a demon from Ghostbusters

    View the video

    Zuul is back. But don’t bother calling the Ghostbusters. Zuul crurivastator is a dino, not a demon. A 75-million-year-old skeleton unearthed in Montana in 2014 reveals a tanklike dinosaur with a spiked club tail and a face that probably looked a lot like its cinematic namesake.

    The find is the most complete fossil of an ankylosaur, a type of armored dinosaur, found...

    Juno spacecraft reveals a more complex Jupiter

    Jupiter’s scientific portrait is getting repainted.

    NASA’s Juno spacecraft swooped within about 5,000 kilometers of Jupiter’s cloud tops on August 27, 2016, giving scientists their first intimate look at the gas giant. The data are revealing surprising details about Jupiter’s gravity, powerful magnetic field and ammonia-rich weather system. The findings, which appear in two studies in...

    Deep heat may have spawned one of the world’s deadliest tsunamis

    Chemical transformations in minerals deep beneath the seafloor could explain why Indonesia’s 2004 mega-earthquake was unexpectedly destructive, researchers report in the May 26 Science. 

    The magnitude 9.2 quake and the tsunami that it triggered killed more than 250,000 people, flattened villages, and swept homes out to sea across Southeast Asia. It was one of the deadliest tsunamis in...

    The Zika epidemic began long before anyone noticed

    The Zika virus probably arrived in the Western Hemisphere from somewhere in the Pacific more than a year before it was detected, a new genetic analysis of the epidemic shows. Researchers also found that as Zika fanned outward from Brazil, it entered neighboring countries and South Florida multiple times without being noticed.

    Although Zika quietly took root in northeastern Brazil in late...

    How a flamingo balances on one leg

    A question flamingo researchers get asked all the time — why the birds stand on one leg — may need rethinking. The bigger puzzle may be why flamingos bother standing on two.

    Balance aids built into the birds’ basic anatomy allow for a one-legged stance that demands little muscular effort, tests find. This stance is so exquisitely stable that a bird sways less to keep itself upright when...

    TRAPPIST-1’s seventh planet is a chilly world

    When astronomers in February announced the discovery of seven planets orbiting a supercool star, details about the outermost planet were sketchy. No more. The seventh planet is chilly and definitely no place for life, the international team reports May 22 in Nature Astronomy.

    The seven-planet system, TRAPPIST-1, is 39 light-years from Earth in the constellation Aquarius. Follow-up...
