    The Lord Howe stick insect is officially back from the dead

    It’s a rare triumph when a species comes back from the dead. A new genetic analysis has officially established what many entomologists and conservation biologists hoped was true: The Lord Howe stick insect (Dryococelus australis) lives.

    Nicknamed “tree lobsters,” the dark-brown crawlers are nocturnal, flightless creatures that can grow up to 15 centimeters long. They feed on tea trees,...

    The way hungry young stars suck in food keeps most X-rays in, too

    View the video

    A plasma cocoon lets growing stars keep their X-rays to themselves. Laboratory experiments that mimic maturing stars show that streams of plasma splash off a star’s surface, forming a varnish that keeps certain kinds of radiation inside.

    That coating could explain a puzzling mismatch between X-ray and ultraviolet observations of growing stars, report physicist Julien...

    The SN 10: Meet the scientists ready to transform their fields

    Earlier this year, General Electric asked a brilliant question: What if scientist Mildred Dresselhaus was treated like a celebrity? The idea, aired as a TV commercial, had many of us smiling at the possibility. In the ad, fans stop the nanoscience pioneer in the street to take selfies, a young girl receives a Dresselhaus doll as a birthday gift and a student sends a Millie emoji after acing a...

    Cosmic lens lets astronomers zoom in on a black hole’s burps

    Astronomers have caught their best look ever at blobs of hot gas fleeing a supermassive black hole, thanks to a new kind of cosmic magnifying glass.

    Anthony Readhead of the Owens Valley Radio Observatory at Caltech and colleagues caught two small, hot bursts traveling away from a bright galaxy called J1415+1320 at near the speed of light. Although the galaxy is billions of light-years...

    A lot of life on planet Earth is awful and incredible

    In deciding on a cover image for this issue, the Science News team had a difficult choice to make: Do we print a picture of a tick that reminds readers how much we all despise these critters? Or, do we go with a closeup view that masks ticks’ revolting character and makes you wonder: “Ooh. What’s that?” We chose to highlight hostilities to match the story headline, “Bulletins from the...

    How earthquake scientists eavesdrop on North Korea’s nuclear blasts

    On September 9 of last year, in the middle of the morning, seismometers began lighting up around East Asia. From South Korea to Russia to Japan, geophysical instruments recorded squiggles as seismic waves passed through and shook the ground. It looked as if an earthquake with a magnitude of 5.2 had just happened. But the ground shaking had originated at North Korea’s nuclear weapons test site...

    Seabirds use preening to decide how to divvy up parenting duties

    Seabirds called common murres appear to use preening as a way to negotiate whose turn it is to watch their chick and who must find food. And when one parent is feeling foul, irregularities in this grooming ritual may send the other a signal that all is not well, researchers report in the July issue of The Auk: Ornithological Advances.

    “The fascinating part of this study is the inference...

    Out-of-body experiments show kids’ budding sense of self

    Kids can have virtual out-of-body experiences as early as age 6. Oddly enough, the ability to inhabit a virtual avatar signals a budding sense that one’s self is located in one’s own body, researchers say.

    Grade-schoolers were stroked on their backs with a stick while viewing virtual versions of themselves undergoing the same touch. Just after the session ended, the children often...

    Baby starfish on the hunt whip up whirlpools

    A baby starfish scoops up snacks by spinning miniature whirlpools. These vortices draw in tasty algae so the larva can slurp them up, scientists from Stanford University report December 19 in Nature Physics.

    Before starfish take on their familiar shape, they swim the ocean as millimeter-sized larvae. They use hairlike appendages called cilia to paddle. The larvae also adjust the...

    Interactive map reveals hidden details of the Milky Way

    There’s much more to the universe than meets the eye, and a new web-based app lets you explore just how much our eyes are missing. Gleamoscope presents the night sky across a range of electromagnetic frequencies. Spots of gamma rays pinpoint distant feeding black holes. Tendrils of dust glow with infrared light throughout the Milky Way. A supernova remnant — the site of a star that exploded...
