The Forgetting Pill Erases Painful Memories Forever
Wired Magazine: Jeffrey Mitchell, a volunteer firefighter in the suburbs of Baltimore, came across the accident by chance: A car had smashed into a pickup truck loaded with metal pipes. Mitchell tried to help, but he saw at once that he was too late. The car had rear-ended the truck at high speed, sending a pipe through the windshield and into the chest of the passenger—a young bride returning home from her wedding. There was blood everywhere, staining her white dress crimson. Mitchell couldn’t get the dead woman out of his mind; the tableau was stuck before his eyes. He tried to tough it out, but after months of suffering, he couldn’t take it anymore.

Getting the point across: Scientists find managers who frequently make pointing gestures tend to be obeyed
Daily Mail: The secret of management may be a lot simpler than most business science courses might have you believe - just point your fingers a lot. Film directors such as Stephen Spielberg do a lot of seemingly meaningless pointing on set - but the gesture helps stamp authority on a chaotic film set. From a very early age, humans associate pointing with teaching and authority - and tend to believe and obey people who point. Psychologists believe we link the gesture to people with knowledge and authority. Simply gesticulating like this may suggest they have greater knowledge and should be obeyed, according to a team from the University of Virginia in Charlottesville.

Unusual suspects: How to make witnesses more reliable
The Economist: To identify a suspect, police typically ask eyewitnesses to pick him out of a line-up of similar-looking folk. Alas, this method is often inaccurate. DNA testing has shown that witnesses often fail to detect the culprit or, worse, wrongfully accuse the innocent. Why should this be? Witnesses may feel under pressure to identify someone as the guilty party, even if they are not sure. Or they could be worried about making a mistake. A new study suggests that witnesses will make more accurate identifications if they do not have to be so precise.

Optogenetics: Stranger Than Fiction
It sounds like a science fiction movie: Scientists integrate the photoreceptive properties of light-sensitive algae into rat neurons. The result? A rat whose brain can be controlled by light. As crazy as it seems, this isn’t science fiction: The field of optogenetics is scientific reality. In a May 2011 talk at the TED Conference, Edward Boyden explained that optogenetics allows scientists to target specific neurons quickly; conventional methods like drugs take longer to kick in. Boyden is also featured in a March Observer article on optogenetics, and he will be speaking in a webinar called Optogenetics in Neurons and Beyond on March 15, 2012.

Placebo Power
APS Fellow and Charter Member Irving Kirsch, associate director of the Placebo Studies Program at Harvard Medical School, says the difference between the effect of a placebo and the effect of an antidepressant is minimal for most people. "People get better when they take the drug, but it's not the chemical ingredients of the drugs that are making them better," Kirsch told Lesley Stael in a 60 Minutes interview, "it's largely the placebo effect." The "placebo effect" may not be all in your head says Kirsch in the interview below: Kirsch, I., Deacon, B.J., Huedo-Medina, T.B., Scoboria, A., Moore, T.J., & Johnson, B.T. (2008).

Perfectionism, Goal Appraisals, and Distress in Students
In case you missed it, the cameras were rolling in Washington, DC. Watch. Watch Gordon L. Flett from York University, Canada and Taryn Nepon of York University, Canada present their research at the 23rd APS Annual Convention in Washington, DC. This study examined perfectionism, goal cognitions, and distress in 95 students. Participants completed the Goal Systems Assessment Battery, along with measures of perfectionism, anxiety, and depression. Socially prescribed perfectionism and perfectionistic thoughts were associated with goal-related self-criticism and negative arousal. Self-oriented perfectionism predicted self-criticism and negative arousal for academic goals.
