How to Tell When Someone Is Lying

‘Many of us believe that we can tell when someone else is lying, and, over the years, a folklore has developed around the facial and physical cues that can give someone away. Liars don’t look you straight in the eye. When someone is lying, he looks up and to the side, as if searching for something. A liar fidgets and seems somehow nervous. Sometimes, he’ll scratch or pull his ear. He’ll hesitate, as if he’s not sure he wants to tell you something. These, however, are all “old wives’ tales,” Leanne ten Brinke, a psychologist at the University of California at Berkeley whose work focusses on detecting deception, told me. “The empirical literature just doesn’t bear that out.” ‘ (The New Yorker).

Scientists Discover How Octopuses Avoid Tying Themselves In Knots

‘There are many things that make the octopus a strange creature, but one of them is that each of its eight arms has an essentially infinite number of positions, and yet each arm operates independently. How does an octopus keep from tying itself in knots?

Or, at least, the kind of people we hang around with on Twitter are noticing. And it’s maybe not a very important demographic, this very weird and specific kind of user: audience-obsessed, curious, newsy. Twitter’s earnings last quarter, after all, were an improvement on the period before, and it added 14 million new users for a total of 255 million. The thing is: Its users are less active than they once were. Twitter says these changes reflect a more streamlined experience, but we have a different theory: Twitter is entering its twilight.’ (The Atlantic).

Watch the Remarkable Shrinking of Jupiter’s Great Red Spot

‘…[S]ightings since the 1930s have shown the spot shrinking. A recent Hubble photo (seen above) observes the Great Red Spot at its smallest size yet —- just over 10,000 miles across, barely big enough for 1.3 Earths to fit inside. Scientists are studying small eddies at the edge of the storm that may somehow be sapping it of its strength. Will this monstrous cyclone continue to downsize? Researchers can’t say for sure.’ (WIRED).

Survivalists Are Using Pinterest to Prepare for the Apocalypse - Colette Shade - The Atlantic

Colette Shade: ‘Pinterest is best known as a destination where people can share affordable wedding ideas, dip recipes, and inspirational quotes pasted over photos of white sand beaches. But a small number of Pinterest users also swap how-tos on building bomb shelters, storing food, and emergency medical care—for “when there are no doctors.”

Meet the preppers of Pinterest.’ (The Atlantic).
