    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...

    Readers question mental health research

    New normal

    People who stay mentally healthy throughout life are exceptions to the rule, a small study suggests. Only 17 percent of study participants experienced no bouts of anxiety, depression or other mental ailments from late childhood to middle age, Bruce Bower reported in “Lasting mental health may be unusual” (SN: 3/4/17, p. 7).

    Reader Lou Floyd found the article disturbing and the...

    Readers question supernova physics

    Supernova surprise

    Astronomers continue to learn a lot from supernova 1987A, which burst onto the scene 30 years ago. Thanks to new detectors that can pick up neutrino signals and even gravitational waves, scientists will be ready when the next nearby star explodes, Emily Conover reported in “Waiting for a supernova” (SN: 2/18/17, p. 24).

    Steve Capps wondered how neutrinos inside an...

    Readers dispute starfishes' water-swirling abilities

    Doomsday preppers

    Dinosaurs and other creatures were largely wiped out 66 million years ago from an asteroid impact, volcanic eruptions or maybe a mix of the two, Thomas Sumner reported in “Devastation detectives” (SN: 2/4/17, p. 16), in the Science News special report “Dino Doomsday.”

    Online reader Mike van Horn wondered if the timing of the v­olcanic eruptions, which happened for h­...

    Data-driven crime prediction fails to erase human bias

    Big data is everywhere these days and police departments are no exception. As law enforcement agencies are tasked with doing more with less, many are using predictive policing tools. These tools feed various data into algorithms to flag people likely to be involved with future crimes or to predict where crimes will occur.

    In the years since Time magazine named predictive policing as one...

    Readers amazed by Amasia

    Saved by the Bell

    Physicists used light from stars to perform a cosmic Bell test, which verified that quantum particles were indeed “spooky,” Emily Conover reported in “Quantum effect passes space test” (SN: 1/21/17, p. 12).

    Reader George Mitchell took issue with Conover’s description of entangled photons before they are measured as having multiple polarizations at once. “We don’t know...

    Power struggle

    Ninety percent of people who believe that they are allergic to penicillin are not, Emily DeMarco reported in “Most penicillin allergies are off base” (SN: 12/24/16 & 1/7/17, p. 5). A recent study found that testing for penicillin allergies reduced by 34 percent the use of vancomycin, described in the story as “a powerful, last-resort antibiotic.”

    Critter calculations

    Savvy for judging quantities is turning up across the animal kingdom — even among spiders and other invertebrates, Susan Milius reported in “Animal math” (SN: 12/10/16, p. 22).

    Some astute readers pointed out that designing experiments to test animals’ quantitative skills takes great ingenuity, but sometimes human bias may skew the results.

    In debate over origin of fairy circles, both sides might be right

    Ecologists still don’t believe in fairies. But it may take magic to resolve a long-running debate over what causes the oddly regular spots of bare soil called fairy circles. A new approach now suggests combining the two main hypotheses.

    Fairy circles, each among about six close neighbors, sprinkle arid grasslands in southern Africa and Australia “like a polka dot dress,” says ecologist...

    Prehistoric tweet

    Researchers uncovered the fossilized voice box, called a syrinx, of an ancient bird that lived 68 million to 66 million years ago. The bird may have sounded like a honking duck, Meghan Rosen reported in “Ancient avian voice box unearthed” (SN: 11/12/16, p. 7).

    Online reader David Spector wondered if researchers could 3-D print the syrinx to replicate the ancient bird’s...
