    How a tiger transforms into a man-eater

    No Beast So FierceDane HuckelbridgeWilliam Morrow, $26.99

    At the heart of No Beast So Fierce is a simple and terrifying story: In the early 20th century, a tiger killed and ate more than 400 people in Nepal and northern India before being shot by legendary hunter Jim Corbett in 1907. Rather than just describe this harrowing tale, though, author Dane Huckelbridge seeks to explain how...

    What happens when the Bering Sea’s ice disappears?

    Peggy’s data were a bit of a shock.

    From an anchored vantage point in an expanse of the southeastern Bering Sea west of Alaska, Peggy, or mooring M2, had monitored conditions in the water for 25 years. A line of sensors extended down more than 70 meters to where Peggy was tethered to the seafloor, collecting information on temperature, salinity and other properties of the water.

  • 50 years ago, doctors lamented a dearth of organ donors

    Number of donors drops —

    Both laymen and surgeons have become faint-hearted about heart transplants.… The rejection and infection problems remain unsolved, and although Dr. [Denton A.] Cooley has performed the greatest number of transplants in the world, he has had to stop operating for lack of donors. — Science News, March 15, 1969

    Microwaved grapes make fireballs, and scientists now know why

    Here’s a recipe for homemade plasma: Cut a grape in half, leaving the two sections connected at one end by the grape’s thin skin. Heat the fruit in a microwave for a few seconds. Then, boom: From the grape erupts a small plasma fireball — a hot mixture of electrons and electrically charged atoms, or ions.

    This trick has been floating around the internet for decades, and previous...

    ‘Skeleton Keys’ unlocks the history and mysteries of bones

    Skeleton KeysBrian SwitekRiverhead Books, $26

    At this very moment, voracious cells are eating away at your bones. Not to worry, though — that’s just a normal part of bone maintenance in healthy adults. The formation of new bone cells balances out the removal of old bone cells. Although bone-making cells rev up when a bone breaks or disease sets in, eventually bone-eating cells kick...

    Nanosponges sop up toxins and help repair tissues

    To take his fledgling lab to new heights, Liangfang Zhang hatched a plan that he considered brilliant in its simplicity. It involved procedures that many of his peers found a little out there. But if he could make his idea work, it would clear a major hurdle to safely ferry therapies through the body on nanoparticles one-thousandth the width of a human hair.

    Yet back in 2010, the young...

    Readers have questions about Ultima Thule, thirsty plants and vitamin D

    Which way is up?

    Initial observations of the Kuiper Belt object MU69, nicknamed Ultima Thule, suggested it had a snowmanlike shape. Ultima Thule’s two lobes are connected by a narrow neck that appears brighter than the rest of the space rock’s surface, Lisa Grossman reported in “New Horizons shows Ultima Thule looks like a snowman, or maybe BB-8” (SN: 2/2/19, p. 7).
