Reading the Look of Love
How fast you can judge whether a person of the opposite sex is looking at you depends on how masculine or feminine they look, according to a new study. The researchers speculate that there may be an evolutionary advantage to quickly noticing when a hottie is looking at you. Psychologists have debated how we determine whether someone else is looking at us or not. One point of view is that "it's almost a geometric problem," says Benedict C. Jones, of the University of Aberdeen in Scotland – that people just look at the whites of the eyes and other features of the face, without being influenced by the face in general.

Can negativity save a failing marriage?
Newlyweds are almost always advised to be upbeat—to have positive expectations for their relationship, to put the best spin on their partner’s actions, and to forgive and forget. Marriage counselors also take (and preach) the view that positive attitudes and actions will strengthen a struggling marriage, even when a little negativity might be well-deserved. So why do half of all couples in therapy fail to save their marriages? Is it possible that this rose-tinted advice is bad advice, that positivity isn’t the cure-all for ailing unions after all?

Tool Manipulation is Represented Similary in the Brains of the Blind and the Sighted
Blind people think about manipulating tools in the same regions of the brain as do people who can see, according to a new study. The researchers say this adds to evidence that the brain has a fairly defined organization, while still being able to adapt to unusual conditions, such as not having any vision. When you look at a glass in front of you on the desk, it sets off a lot of reactions in your brain. Part of your brain categorizes it: "That's a glass!" Another part of the brain thinks about the glass's shape and size, its exact location, and what you would have to do with your hand and arm if you were going to reach out and grab it.

Does believing soothe the worried mind?
Religious beliefs date back at least 100,000 years. That’s the time when our Neanderthal cousins began burying their dead with weapons and tools—presumably prepping them for the world beyond the grave. And such beliefs persist today, with the vast majority of modern humans in every corner of the globe espousing some kind of religious conviction. But why? The antiquity and universality of belief suggest that it serves some fundamental psychological purpose, but what would that be? A small but growing number of psychological scientists have been exploring these questions, focusing on the idea that religious belief may be a natural consequence of the human mind at work.

Brain Structure Corresponds to Personality
Personalities come in all kinds. Now psychological scientists have found that the size of different parts of people's brains correspond to their personalities; for example, conscientious people tend to have a bigger lateral prefrontal cortex, a region of the brain involved in planning and controlling behavior. Psychologists have worked out that all personality traits can be divided into five factors, commonly called the Big Five: conscientiousness, extraversion, neuroticism, agreeableness, and openness/intellect. Colin DeYoung at the University of Minnesota and colleagues wanted to know if these personality factors correlated with the size of structures in the brain.

Innovation: Who Else Is Doing It?
Bloomberg: Everyone applauds innovation. At least, they love it in retrospect, after it has worked. Before that, it's just somebody's wild idea that competes with every other wild idea for resources and support. What sounds great in the abstract seems risky when translated to a specific unproven idea. For that reason, executives who tell me that they want more innovation sometimes ask, as their first question, "Who else is doing it?" Or they say, "We want more innovation; we just don't want to be the first." I hate to point out the irony to them. Guys, innovation means maybe no one else is doing it. You might have to be the first. And that might be a good thing.
