Dining: Bugged on Thanksgiving
Earlier this week, I met with Zack Lemann at the Insectarium, a roughly 18-month-old Audubon museum. He gave me a behind-the-scenes tour of its dozens of living exhibits hosting insects and more -- including tarantulas and, arriving that day for their Tuesday debut, white (non-albino) alligators. But the purpose of my noon-hour visit was to sample the local cuisine and learn details of preparations for a holiday menu that would be offered through tomorrow at the facility’s experiential cafe: Bug Appetit. There’s Thanksgiving turkey with a cornbread and wax worm stuffing, cranberry sauce with meal worms, and Cricket Pumpkin Pie. It’s cuisine most Americans would never pay for. But at the Insectarium, they don’t have to. It’s offered free as part of an educational adventure.

Beefy hormones: New routes of exposure
On any given day, some 750,000 U.S feedlots are beefing up between 11 million and 14 million head of cattle. The vast majority of these animals will receive muscle-building steroids — hormones they will eventually excrete into the environment. But traditional notions about where those biologically active pollutants end up may need substantial revising, several new studies find.
