Clarification about ticks, correction on Madea photo

Clarification: The lead paragraph of last week's cover story, "Up tick: Why you should be worried about Lyme disease," implies that ticks are insects. They're actually arachnids, joint-legged invertebrates which fall in a different class of animals from insects.

Correction: Due to a production template error in the May 12 issue, the caption for movie still from Madea's Big Family Reunion was the same as the caption for a still for another film depicted in that space the previous week.
