I Just Bought a Bunch of Stuff!
- Murderous Maths (it's British so it's wonky--"Maths" not "Math"... not to say that all things British are necessarily wonky--sorry my British friends!)
- A couple of Draw-Write-Now books We'll see if the kids like them or if they're too smarmy. My kids do not suffer smarmy lightly, so I hope these will just be fun and not too pointedly teachy.
- The Stunning Science of Everything from the Horrible Science series which looks like a nice overview of everything--basic ideas any way.
- A couple of David Macaulay books because it is so interesting to see his exploded diagrams and cross sections of buildings and machines and underground tunnels. He is a brilliant illustrator and the kids love his books.

Mercury Exposure is Unhealthy? What?!
The reason, of course, is that mercury is a known neurotoxin, especially dangerous to developing brains. For decades anti-mercury activists have pushed the industry to develop substitutes (so-called composites, or resins, are now available), and even to persuade people to have their fillings ripped out, but have made very little headway.
Now they have won a big one. In a legal settlement signed last week, the U.S. Food and Drug Administration has changed the information on its Web site about amalgam fillings to say that they “may have neurotoxic effects on the nervous systems of developing children and fetus,” and that pregnant women “should not avoid seeking dental care, but should discuss options with their health practitioner.” Previously, there was no such warning. The FDA also agreed to decide by next year whether mercury fillings need more regulation.
The FDA had been dragging its feet for so long on mercury in dental fillings that even the judge, Ellen Segal Huvelle of U.S. District Court for the District of Columbia, castigated the agency: “This is your classic failure to act,” she said. (The case is Moms Against Mercury et al. v. Von Eschenbach, Commissioner, et al. The “et al” plaintiffs are other consumer and environmental groups, as well as state officials.)
