Thirtysomethings flex their number sense
ScienceNews: Even 6-month-old babies can rapidly estimate approximate numbers of items without counting. But surprisingly, an apparently inborn sense for numbers doesn’t top out until around age 30. Number sense precision gradually declines after that, generally falling to preteen levels by about age 70, say psychologist Justin Halberda of Johns Hopkins University in Baltimore and his colleagues. They report the findings, based on Internet testing of more than 10,000 volunteers ages 11 to 85, online the week of June 25 in the Proceedings of the National Academy of Sciences.

Is Feeling Bad a Luxury Problem?
In Judith Viorst’s classic children’s book, Alexander and the Terrible, Horrible, No Good, Very Bad Day, Alexander wakes up with chewing gum in his hair—and everything goes downhill from there. He trips on his skateboard, and drops his sweater in the sink. He doesn’t get a window seat in the car, and the dentist tells him he has a cavity. His mother makes him get white sneakers, instead of the blue and red-striped ones he coveted. He’s forced to eat lima beans for dinner, and there’s kissing on TV. To top it all, his nightlight burns out just as he’s getting ready for bed. Alexander's plight resonates not just for kids, but also for any adult who has ever whined about a luxury problem.

How to fool Houdini and avoid fooling yourself
Scientific American: Last week, Alex Stone taught Wall Street Journal readers the world round how to steal a watch. It’s probably a safe bet that fellow magicians were none too pleased. Nor are they likely to have gotten a kick out of Stone’s new book, Fooling Houdini (out today), where the watch theft maneuver is but one of the effects that the amateur magician so shamelessly reveals. Shamelessly, that is, if you’re playing by the traditional rules of magic conduct, where, as Stone puts it, “exposure is seen as a form of vandalism,” something that “deadens the mystery and tarnishes the brand, shrinking all the grandeur in magic to the scale of an intellectual puzzle.” But does it really?
