People are over confident despite errors
Business Standard: A new study suggests that overprecision is a common and robust form of overconfidence driven, at least in part, by excessive certainty in the accuracy of our judgments. The research, conducted by researchers Albert Mannes of The Wharton School of the University of Pennsylvania and Don Moore of the Haas School of Business at the University of California, Berkeley, revealed that the more confident participants were about their estimates of an uncertain quantity, the less they adjusted their estimates in response to feedback about their accuracy and to the costs of being wrong.

Study: Women Better At Remembering Faces Than Men
CBS: Women spend more time studying facial features than men, thus making them better at remembering faces than their male counterparts. A new study from Canadian researchers found that women have a heightened attention toward facial features on a subconscious level. “We discovered that women look more at new faces than men do, which allows them to create a richer and more superior memory,” said study co-author Jennifer Heisz, an assistant kinesiology professor at McMaster University in Hamilton, Ontario, in a news release.

Why Do We Remember Faces but Not Names?
NPR Science Friday: It’s happened to all of us: We're at an event and recognize peoples’ faces all over the room, but names utterly escape us. Don’t feel bad. When it comes to linking faces and names, the deck is stacked against us from evolutionary, neuroanatomical, and practical perspectives. For starters, our brains are far better equipped at storing visual data, such as a face, than a briefly heard name. “We are visual creatures,” says E. Clea Warburton, a cognitive neuroscientist at the University of Bristol. “Our brain has got more cortex devoted to processing visual information compared to that from our other senses.

Letting Go of Keeping Up
The Atlantic: Everyone's heard of the phrase, "Keeping up with the Joneses," which refers to the phenomenon of using one's neighbors as a standard of comparison for the consumption of material goods. (For example: it's hard not to notice when your neighbor buys a luxury sports car, and it's even harder to keep yourself from wondering whether it might be time for you to upgrade as well...even if it means reducing contributions to your retirement fund to pay for it.) Our neighbors, however, are no longer our only salient standard of comparison.

Blood vessels behind eyes are secret to the age of the human brain
Times of India: The secret behind the actual age of your brain is inside your eyes. Scientists have found that the width of blood vessels in the retina, located at the back of the eye, may indicate brain health years before the onset of dementia. Retinal blood vessels share similar size, structure, and function with blood vessels in the brain and can provide a way of examining brain health in living humans. Individuals who had wider retinal venules showed evidence of general cognitive deficits, with lower scores on numerous measures of neuropsychological functioning, including verbal comprehension, perceptual reasoning, working memory and executive function.

Would You Accept DNA From A Murderer?
NPR: Modern medicine and technology can change the way we define our physical and psychological selves. Is a prosthetic arm "your own arm" in the same sense that its biological predecessor seemed to be? Might taking antipsychotic medication fundamentally change your personality? Could an organ transplant from a pig, or from a violent murderer, somehow change who you are? Understanding how people think about significant medical interventions not only has practical implications, it can also shed light on how people conceptualize themselves and their bodies.
