A Captive African Elephant Calf Exhibits Precocious Social Relationships
African elephants (Loxodonta africana) in their native habitats live in groups of 2 to 50 elephants called family units, usually containing genetically related adult females and calves and juveniles of both sexes. A calf spends most of its time near its mother. Older calves increase the time they spend with other members of the family unit. “Allomothers,” usually young female relatives, assist in rearing a calf by providing comfort and safety. The dominant animal in the group (the “matriarch”) plays a critical role in group dynamics and survival.

Language, Mind, and Human Nature
Hailed as one of the world’s most influential people, experimental psychologist Steven Pinker’s interests span all aspects of language, mind, and human nature. In his classic book The Language Instinct, Pinker argues that languages are learned but that language is an instinct — an evolutionary adaptation for the communication of complex ideas. Pinker has studied the meaning and acquisition of verbs, and what they tell us about concepts of causation, space, time, and intentions.

Why You Should Freak Out More, Not Less, Over Your Profile Photos
New York Magazine: We've all spent too much time obsessing over our profile pictures on Facebook, dating websites, and everywhere else. It would be nice to think we're being neurotic, that it doesn't actually matter whether you use that photo where you look coy-happy or the one where you're a bit more mischievous-happy. But a new study in Psychological Science suggests otherwise: Even subtle differences between photos of the same person can greatly alter others' first impressions of them. Look at the images above.

George Washington Trumps Pinocchio When It Comes to Promoting Honesty in Kids
Pacific Standard: Once upon a time, a group of researchers began to wonder whether telling children traditional stories meant to instill a sense of honesty actually worked. So they took three classic tales, shared them with three- to seven-year-olds, and waited for the results. To their surprise, they found only one story—the one about young George Washington chopping down the cherry tree—was effective in getting fibbing kids to fess up. While hearing that tale produced only a modest improvement in honesty, the other two stories had no impact whatsoever. Read the whole story: Pacific Standard

Blame Your Brain: The Fault Lies Somewhere Within
NPR: Science doesn't just further technology and help us predict and control our environment. It also changes the way we understand ourselves and our place in the natural world. This understanding can inspire awe and a sense of grandeur. But it can also be unsettling, especially when it calls into question our basic assumptions about the kinds of creatures we are and the universe we inhabit. Current developments in neuroscience seem to be triggering precisely this jumble of reactions: wonder alongside disquiet, hope alongside alarm. Read the whole story: NPR

Job Insecurity: It’s Not Just the Economy, Stupid
The economic instability that has swept the globe over the last six years has largely snuffed people’s confidence in their job security. And that wariness does nothing to improve organizations’ financial success. A 2008 study showed that job insecurity erodes commitment and performance, not to mention health. The pessimism in the workforce could therefore create a vicious cycle of lackluster economic growth; as workers worry about getting pink slips, their productivity declines and profits drop. And as profits drop, workers fret even more about their jobs.
