A Simple App For A Happier Life
Forbes: There are more social apps out there these days drawing inspiration from social science researches – and maybe rightly so.

Superhero or Supervillain?
Slate: From invisibility to superhuman strength to telekinesis, a wave of emerging technologies promise to give people powers once reserved for comic-book characters. Which raises an important question: If humans become superhuman, will we turn out to be superheroes—or supervillains? ... The findings suggest that acquiring a superpower can spark benevolent tendencies. Give someone Superman’s abilities, and she’ll start to behave a little more like Superman. Clinical psychologist Robin Rosenberg, who helped design the experiment, said its outcome supported her hypothesis that people might treat an extraordinary ability as a sort of gift that brings with it a responsibility to help others.

People who gain weight are more likely to give in to temptations but also are more thoughtful about their actions, according to a new study published in Psychological Science, a journal of the Association for Psychological Science. To understand how fluctuations in body weight might relate to personality changes, psychological scientist Angelina Sutin of the Florida State University College of Medicine and colleagues at the National Institutes of Health (NIH) examined data from two large-scale longitudinal studies of Baltimore residents. “We know a great deal about how personality traits contribute to weight gain,” said Sutin.

Fearful expressions help pin-point danger
The Telegraph: Researchers found that the expressions people pull when they are frightened enlarge their visual field whilst simultaneously signalling to others around them where to look for threats. Therefore the expressions are functional in ways that directly benefit both the person who makes the expression and the person who observes it, it is claimed. The findings show that widened eyes provide a wider visual field which can help us to locate potential threats in our environment. These widened eyes also help to send a clearer gaze signal telling observers to "look there" - which may enhance their ability to locate the same threat, as well.

Are Doctors Diagnosing Too Many Kids with ADHD?
Scientific American: A German children's book from 1845 by Heinrich Hoffman featured “Fidgety Philip,” a boy who was so restless he would writhe and tilt wildly in his chair at the dinner table. Once, using the tablecloth as an anchor, he dragged all the dishes onto the floor. Yet it was not until 1902 that a British pediatrician, George Frederic Still, described what we now recognize as attention-deficit hyperactivity disorder (ADHD). Since Still's day, the disorder has gone by a host of names, including organic drivenness, hyperkinetic syndrome, attention-deficit disorder and now ADHD.
