    The mystery of vanishing honeybees is still not definitively solved

    It was one of the flashiest mysteries in the news about a decade ago — honeybee workers were vanishing fast for no clear reason. To this day, that puzzle has never been entirely solved, researchers acknowledge.

    And maybe it never will be. Colony collapse disorder, or CCD, as the sudden mass honeybee losses were called, has faded in recent years as mysteriously as it began. It’s possible...

    Fast radio bursts may be from a neutron star orbiting a black hole

    OXON HILL, Md. — Fast radio bursts could come from a turbulent home. At least one source of these bright, brief blasts of radio energy may be a young neutron star assisted by a nearby massive black hole, new research suggests.

    “The biggest mystery around fast radio bursts is how such powerful and short-duration bursts are emitted,” says astronomer Daniele Michilli of the University of...

    How to keep humans from ruining the search for life on Mars

    T he Okarian rover was in trouble. The yellow Humvee was making slow progress across a frigid, otherworldly landscape when planetary scientist Pascal Lee felt the rover tilt backward. Out the windshield, Lee, director of NASA’s Haughton Mars Project, saw only sky. The rear treads had broken through a crack in the sea ice and were sinking into the cold water.

    True, there are signs of...

    Hormone replacement makes sense for some menopausal women

    Internist Gail Povar has many female patients making their way through menopause, some having a tougher time than others. Several women with similar stories stand out in her mind. Each came to Povar’s Silver Spring, Md., office within a year or two of stopping her period, complaining of frequent hot flashes and poor sleep at night. “They just felt exhausted all the time,” Povar says. “The joy...

    White dwarf’s inner makeup is mapped for the first time

    Astronomers have probed the inner life of a dead star. Tiny changes in a white dwarf’s brightness reveal that the stellar corpse has more oxygen in its core than expected, researchers report online January 8 in Nature. The finding could challenge theories of how stars live and die, and may have implications for measuring the expansion of the universe.

    As a star ages, it sheds most of its...

    Smothered jet may explain weird light from neutron star crash

    View the video

    The neutron star collision heard and seen around the world has failed to fade. That lingering glow could mean that a jet of bright matter created in the crash has diffused into a glowing, billowy cocoon that surrounds the merged star, researchers report online December 20 in Nature.

    Gravitational waves from the collision between two ultradense stellar corpses was...

    Specialized protein helps these ground squirrels resist the cold

    The hardy souls who manage to push shorts season into December might feel some kinship with the thirteen-lined ground squirrel.

    The critter hibernates all winter, but even when awake, it’s less sensitive to cold than its nonhibernating relatives, a new study finds. That cold tolerance is linked to changes in a specific cold-sensing protein in the sensory nerve cells of the ground...

    Saturn’s rings are surprisingly young and may be from shredded moons

    NEW ORLEANS — Saturn’s iconic rings are a recent addition. Final data from the Cassini spacecraft, which flew between the planet and the rings this year before plunging into the gas giant’s atmosphere, show the rings are around a few hundred million years old and less massive than previously thought.

    Those findings suggest the rings are probably the remnants of at least one moon, rather...

    Brains of former football players showed how common traumatic brain injuries might be

    There have been hints for years that playing football might come at a cost. But a study this year dealt one of the hardest hits yet to the sport, detailing the extensive damage in football players’ brains, and not just those who played professionally.       

    In a large collection of former NFL players’ postmortem brains, nearly every sample showed signs of chronic traumatic...

    What hospitals can do to help keep excess opioids out of communities

    To halt the misuse of opioids, it may help to slash the number of pills prescribed, a new study suggests.

    Five months after the implementation of new opioid prescription guidelines at a University of Michigan hospital, roughly 7,000 fewer pills went home with patients — a drop that might reduce the risk of accessible pills leading to substance abuse. But the opioid reduction didn’t leave...
