    Once settled, immigrants play important guard roles in mongoose packs

    View the video

    Immigrants, they get the job done — eventually. Among dwarf mongooses, it takes newcomers a bit to settle into a pack. But once these immigrants become established residents, everyone in the pack profits, researchers from the University of Bristol in England report online December 4 in Current Biology.  

    Dwarf mongooses (Helogale parvula) live in groups of around 10...

    Hidden hoard hints at how ancient elites protected the family treasures

    BOSTON — Long before anyone opened a bank account or rented a safe deposit box, wealth protection demanded a bit of guile and a broken beer jug. A 3,100-year-old jewelry stash was discovered in just such a vessel, unearthed from an ancient settlement in Israel called Megiddo in 2010. Now the find is providing clues to how affluent folk hoarded their valuables at a time when fortunes rested on...

    A new map exhibit documents evolving views of Earth’s interior

    Much of what happens on the Earth’s surface is connected to activity far below. “Beneath Our Feet,” a temporary exhibit at the Norman B. Leventhal Map Center in the Boston Public Library, explores the ways people have envisioned, explored and exploited what lies underground.

    “We’re trying to visualize those places that humans don’t naturally go to,” says associate curator Stephanie Cyr...

    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,...

    Alzheimer’s protein can travel from blood to build up in the brain

    An Alzheimer’s-related protein can move from the blood to the brain and accumulate there, experiments on mice show for the first time.

    The results, published online October 31 in Molecular Psychiatry, suggest that the protein amyloid-beta outside the brain may contribute to the Alzheimer’s disease inside it, says Mathias Jucker, a neurobiologist at the University of Tübingen in Germany....

    Here’s why some water striders have fans on their legs

    For an animal already amazing enough to walk on water, what could growing feather fans on its legs possibly add?

    These fans have preoccupied Abderrahman Khila of the University of Lyon in France, who keeps some 30 species of bugs called water striders walking the tanks in his lab without getting their long, elegant legs wet.

    “Walk” may be too humdrum a word. The 2,200 or so known...

    Wind may be driving the melting of East Antarctica’s largest glacier

    View the video

    The wind is helping to awaken one of Antarctica’s sleeping giants. Warm ocean waters, driven inland by winds, are undercutting an ice shelf that holds back a vast glacier from sliding into the ocean, researchers report November 1 in Science Advances.

    Totten Glacier is East Antarctica’s largest glacier, with a drainage basin encompassing about 550,000 square...

    The newest AlphaGo mastered the game with no human input

    AlphaGo just leveled up.

    The latest version of the computer program, dubbed AlphaGo Zero, is the first to master Go, a notoriously complex Chinese board game, without human guidance. Its predecessor — dubbed AlphaGo Lee when it became the first computer program with artificial intelligence, or AI, to defeat a human world champion Go player (SN Online: 3/15/16) — had to study millions of...

    New physics books don’t censor the math behind reality

    Many books about science are meant to be pleasure reading. Such books attempt to convey the wonder and fascination and excitement of science, and ideally some of the substance as well. After all, good popular science writing is not only engaging and entertaining, but also informative. But even very informative popular books are not designed to be fully educational about the science in...

    An American astronomical evangelist coined the phrase ‘island universe’

    No other science engages human curiosity like astronomy. From antiquity onward, attempts to comprehend the architecture of the cosmos have commanded a substantial fraction of humankind’s mental budget for intellectual endeavor. Only in the last century, though, have astronomers grasped the structure of the cosmos accurately. Just a hundred years ago, a great debate raged about the fuzzy...
