  • Yellowstone wolves may not have transformed the national park after all
    on February 12, 2026 at 1:51 pm

    A new scientific review challenges the headline-grabbing claim that Yellowstone’s returning wolves triggered one of the strongest trophic cascades on Earth. Researchers found that the reported 1,500% surge in willow growth was based on circular calculations and questionable comparisons. After correcting for modeling and sampling flaws, the supposed ecosystem-wide boom largely disappears.

  • H5N1 bird flu kills more than 50 skuas in first Antarctica wildlife die off
    on February 12, 2026 at 6:31 am

    For the first time, deadly H5N1 bird flu has been confirmed as the cause of a wildlife die-off in Antarctica, killing more than 50 skuas during the 2023–2024 summers. Researchers on an Antarctic expedition found the virus ravaging these powerful seabirds, with some suffering severe neurological symptoms—twisted necks, circling behavior, and even falling from the sky. While penguins and fur seals were examined, skuas emerged as the primary victims, especially on Beak Island, where a mass die-off occurred.

  • Gray wolves are hunting sea otters and no one knows how
    on January 30, 2026 at 3:29 pm

    On a remote Alaskan island, gray wolves are rewriting the rulebook by hunting sea otters — a behavior few scientists ever expected to see. Researchers are now uncovering how these coastal wolves adapted to marine hunting, what it means for land–sea ecosystems, and whether this ancient predator–prey relationship is re-emerging as sea otters recover.

  • Scientists ranked monogamy across mammals and humans stand out
    on January 23, 2026 at 4:58 am

    A new study suggests humans belong in an elite “league of monogamy,” ranking closer to beavers and meerkats than to chimpanzees. By comparing full and half siblings across species and human cultures, researchers found that long-term pair bonding is unusually common in our species. Even societies that permit polygamy show far more monogamy than most mammals. This rare evolutionary shift may have played a key role in human social success.

  • Decoding the perfect steak: The hidden DNA behind Wagyu’s legendary marbling
    on January 12, 2026 at 7:01 am

    A groundbreaking cattle genome has given researchers their clearest look yet at what makes Wagyu beef so special. By uncovering hundreds of new genes and hidden genetic variations, scientists can now pinpoint traits linked to marbling, health, and productivity with far greater accuracy. The advance could boost profits for beef producers while improving breeding outcomes across many cattle breeds. It also sets the stage for even more comprehensive livestock genomes in the future.
