Could cannibal Hannibal Lecter be capable of empathy? Psychopaths do have empathy, researchers say, but it doesn't come naturally. A brain-imaging study of 18 violent, psychopathic criminals in the Netherlands, the largest such study undertaken, suggests they can summon empathy when prompted. The report, published Wednesday in the journal Brain, showed that empathic circuits that are unconsciously activated in the brains of normal people may be dormant or switched off in psychopaths -- not absent, as commonly thought.

August is a great month for celebrating human stupidity. On Aug. 6, 1945, we all but disappeared Hiroshima with a single atomic bomb, and then did it again, three days later, at Nagasaki. And now we barely seem to care. The sad truth is, we are incapable of understanding exactly what these seemingly ancient events mean - right now, for all of us, today. The August anniversaries are a stark reminder that the brains we inherited from our ancestors simply may not be up to dealing with much of the modern world we've (they've)

Do women who are on the autism spectrum have brains that are more “masculine”? A team of researchers at Cambridge University's Autism Research Center has found striking similarities between the structural anomalies found in the brains of women with autism spectrum disorder and neurobiological characteristics known to be different between males and females in general. The results, published online Thursday in the review Brain , partially confirm aspects of an “extreme male brain” theory of autism put forth by Cambridge neuroscientist Simon Baron-Cohen and his colleagues.

Attention pregnant women: If you want to help your child get into Harvard, lace up those sneakers and exercise! Hardly a week goes by without science delivering new evidence that exercise boosts the brain. Studies have linked exercise to brain health in senior citizens , middle-aged adults and kids . A trio of researchers from the University of Montreal figured the same might hold true for babies in utero as well. Dave Ellemberg and Daniel Curnier, two professors from the university's Department of Kinesiology, and graduate student Elise Labonte-LeMoyne recruited women who were in their first trimester of pregnancy and randomly assigned them to an “active” or “sedentary” group.

The next cures for bacterial infections may come from an unlikely place: cockroach brains. Tissues from cockroach and locust brains and nervous systems killed off 90% of E. coli and MRSA bacteria without harming the human cells they were attacking, according to researchers from the University of Nottingham. The findings, released Saturday, are being presented this week at the autumn meeting of the Society for General Microbiology in Nottingham, Great Britain. The researchers suspect it’s the proteins in the insect brains that so effectively kill the bacteria.

The big trouble, in Kurt Vonnegut's view, is our big brains. "Our brains are much too large," Vonnegut said. "We are much too busy. Our brains have proved to be terribly destructive." Big brains, Vonnegut said, invent nuclear weapons. Big brains terrify the planet into worrying about when those weapons will be used. Big brains are restless. Big brains demand constant amusement.
