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.

Re "Ancient brains, modern dilemmas," Opinion, Aug. 12 I enjoyed this article immensely, so much so that my cortex directed me to read it carefully - twice. Cole's connection between disbelief and apathy about global warming and the reptilian brain was of particular interest to me. Because these attitudes tend to fall along party lines, I quickly thought (perhaps with my lizard brain) that the party whose members often eschew global warming science should be renamed the Reptilian Party.

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 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.

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)

Here's something for raw-food aficionados to chew on: Cooked food might be a big reason humans were able to grow such large brains compared to their body size, scientists say. If modern human ancestors had eaten only raw food, they'd have to regularly feed more than nine hours a day, according to a study published online Monday in Proceedings of the National Academy of Sciences. A pair of researchers from the Instituto Nacional de Neurociéncia Translacional in São Paulo, Brazil, decided to try and help explain why modern humans' brains were able to grow so large compared to their body size and why other primates' brains did not. They looked at the relative brain-to-neuron-counts of a host of primates, from owl monkeys to baboons.
