There's a report of Simon Baron-Cohen's recent study suggesting that highly analytical couples, such as scientists, may be more likely to produce children with autism. I don't think his labeling of people such as scientists, mathematicians and engineers as 'systemizers' will surprise anyone, or his suggestion that such people tend to be less social. The suggestion that the rise in autism (if real) can be attributed to greater opportunities for systemizers to meet each other is ... well, an intriguing idea ... but I'd hold off on trying to breed systemizers out of the gene pool!

On a lighter note, read about the choral abilities of some wrens: "the first four-part, synchronized chorus with alternating parts recorded outside human music"!

And to further relax you, here's an optical illusion.
