Fats stimulate binge eating
Much like marijuana, fatty foods can spur overeating, a study in rats shows. The new finding also suggests possible therapies to combat the munchies.

Some comfort about broken CFLs
My night-owl daughter woke me in a panic at around 2 a.m., a couple of weeks back. While swatting at a fly, she’d just broken the compact fluorescent light illuminating her closet. Having heard me warn endlessly of how we should be careful in handling these bulbs — since they contain mercury — she wanted to know what kind of damage control was called for. I only wish I knew then what I do now.

Cans bring BPA to dinner, FDA confirms
Federal chemists have confirmed what everyone had expected: that if a bisphenol-A-based resin is used to line most food cans, there’s a high likelihood the contents of those cans will contain at least traces of BPA.
