  • 50 years ago, continental drift began to gain acceptance

    Drifting theories shake up geology

    Continental drift, a theory often considered amusing but rarely important, seems about to become the focus of a revolution in geology. At the least, it has already split the geological community into those who find the evidence for it “formidable” and those who think it is not yet formidable enough to constitute a proof. — Science News, April 29,...

    Scientists find amazement in what’s most familiar

    For her 7th birthday, my niece received a very special gift — a compound light microscope with a set of slides. As soon as we got it out of the package, she became a diligent young investigator, studying the leg of a fly, dog cardiac muscle and onion epidermal cells. But it wasn’t the prepared slides that captivated her most. She wanted to investigate more familiar things. We plucked...

    Readers bugged by wine-spoiling stinkbugs

    Eau de stinkbug

    Stinkbugs accidentally harvested with grapes and fermented during the wine­making process release a pungent stress compound. It takes only three stinkbugs per grape cluster to ruin red wine’s taste, Elizabeth S. Eaton reported in “Red wine has stinkbug threshold” (SN: 3/18/17, p. 5).

    “Does contamination of wine by the bugs’ stress compound pose any health risk to...

    Venomous fish have evolved many ways to inflict pain

    Biologist Leo Smith held an unusual job while an undergraduate student in San Diego. Twice a year, he tagged along on a chartered boat with elderly passengers. The group needed him to identify two particular species of rockfish, the chilipepper rockfish and the California shortspine thornyhead. Once he’d found the red-orange creatures, the passengers would stab themselves in the arms with the...

    There’s still a lot we don’t know about the proton

    Nuclear physicist Evangeline Downie hadn’t planned to study one of the thorniest puzzles of the proton.

    But when opportunity knocked, Downie couldn’t say no. “It’s the proton,” she exclaims. The mysteries that still swirl around this jewel of the subatomic realm were too tantalizing to resist. The plentiful particles make up much of the visible matter in the universe. “We’re made of them...
