From a Chinese satellite drifting through suborbital space, a laser beamed pairs of entangled photons to two separate locations on the ground. Although 746 miles separated each member of the pair, the light particles remained mysteriously connected.

American and Chinese defense giants are moving quickly to reach the edge of space, aiming to launch hypersonic aircraft that can cross continents in under an hour. What exactly does hypersonic mean? Speeds of over Mach 5, or more than 3,835 miles per hour.
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.
Imagine: vast expanses of frozen sea, stretching from the northern coast of Alaska into the Arctic horizon. Welcome to the Southern Beaufort Sea—or at least, the Southern Beaufort Sea as it used to be. This icy Arctic ecosystem is dominated by the majestic polar bear, but warmer temperatures are changing both the landscape and its inhabitants.
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.

Natural forces shape every inch of our globe, but in California, the two big players are water falling out of the sky (or the lack thereof) and earthquakes.
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.
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.
