Tuning a golf club's signature "thwack" sound costs millions

In 2007, Nike introduced a driver called the Sumo. It was immediately identifiable because of its square head shape as well as the signature sound it made when impacting the ball. The noise in question was a loud “clank” that many players found annoying. “The Sumo had a very strong frequency content around 2,000-3,000 hertz,” says Daniel A. Russell, a professor of acoustics at Pennsylvania State University's College of Engineering.

Toxic mercury levels are actually declining in Alaskan polar bears—but that's not as great as it sounds

Imagine: vast expanses of frozen sea, stretching from the northern coast of Alaska into the Arctic horizon.

El Niño has given us a preview of West Antarctica's future, and things do not look good. For two weeks in January of 2016, unusually warm weather caused a 300,000 square mile patch of the Ross Ice Shelf to partially melt. The roughly Texas-sized area, blanketed in a slushy mixture of ice and water, represents one of the first times scientists have been able to catch such widespread Antarctic melting in action. The findings were published this week in Nature Communications.

How a 93-year-old war vet (and his sneakers) are helping NASA track pollution

On a recent Sunday morning, 93-year-old Bernie Fowler laced up his white sneakers and waded into Maryland's Patuxent River, a tributary of the Chesapeake Bay, just as he has done every June for the past 30 years. He was conducting his annual test of water clarity by seeing how deep he could go and still see the tops of his shoes.

Fancy wine descriptions can make you feel more emotional when you drink

I think we can all admit to getting a little emotional after a few too many glasses of wine. But according to a study done at the University of Adelaide, our emotional response to wine actually begins much earlier. They found that wine descriptions could make study subjects feel more emotional about booze, perhaps making them more likely to buy it as a result.
