...seems. Just look at the set of new pitching rules that Little League is putting into effect for the 2007 season. After decades of trying to prevent injuries by limiting pitchers to six innings a game--which could result in anywhere from 54 to more than 100 pitches per outing--Little League officials will focus instead on the total number of pitches per game, depending on the pitcher's age.

Netting 178 species of songbirds and testing their blood and feathers, Evers found that all of them were indeed contaminated, some in concentrations exceeding 0.1 parts per million. That doesn't sound like much, but it's a lot higher than it ought to be, and it's surely on the rise. So far, the toxin hasn't disrupted the birds' reproductive cycle, but researchers fear that it will before long. What's more, if the birds...
