Oxytocin Boosts Dishonesty
The Scientist: The hormone oxytocin is usually associated with positive traits like trust, cooperation, and empathy, but scientists have now found that it can make people more dishonest when their lies serve the interests of their group. “This is the best evidence yet that oxytocin is not the ‘moral molecule,’” said Carsten de Dreu from the University of Amsterdam, who co-led the study, which was published today (March 31) in PNAS. “It doesn’t make people more moral or immoral.

Life Is Short, Proust Is Long
The New Yorker: Of all the forms of entertainment, reading is the most laborious. Doing the voices of fictional characters in your head is hard. Remembering their names is also hard. Prolonged sitting, we are told, is as bad for us as smoking. Reading is abysmally sedentary. All motion is confined to the eyes, and there the mechanics are ungainly. The human retina is a sensor that is weakest at its edges. Only at its very center, in a region called the fovea, do we see with sufficient acuity to tell individual letters apart. The fovea is small, just wide enough to encompass eight characters. When we read, we are peering through this pinhole. The analogy is with a blinkered horse. ...

The Purposeful Life (Hint: Don’t Wait for Retirement)
The Huffington Post: I have several close friends who are contemplating retirement, and a few have been teetering on that decision for a while.

Truth or lie – trust your instinct, says research
BBC: We are better at identifying liars when we rely on initial responses rather than thinking about it, say psychologists. Generally we are poor at spotting liars - managing only slightly better than flipping a coin. But our success rate rises when we harness the unconscious mind, according to a report in Psychological Science. "What interested us about the unconscious mind is that it just might really be the seat of where accurate lie detection lives," said Dr Leanne ten Brinke of the University of California, Berkeley.

Therapists’ Apps Aim To Help With Mental Health Issues
NPR: Games like Flappy Bird and Candy Crush have helped many of us de-stress during long waits at the doctor's office and crowded Metro rides. But what if an app could actually help with mental health? Researchers from Hunter College and the City University of New York say they've developed an app that can reduce anxiety. In the game, called PersonalZen, players encounter two animated characters in a field of grass. One of them looks calm and friendly, while the other looks angry. Soothing music plays in the background. When one creature burrows into the grass, players must follow the rustling leaves and trace its path.
