If they try to investigate the site and it's a trap, the Yeerks could find out who they are. If they don't check it out, they'll never know if they're the only ones fighting.

For decades, it has been nearly universal dogma among environmentalists and health advocates that cattle and beef are public enemy number one. But is the matter really so clear? Hardly, argues environmental lawyer turned rancher Nicolette Hahn Niman in her new book, Defending Beef.

In Defending Beef, Hahn Niman argues that cattle are not inherently bad for either the Earth or our own nutritional health.

Dip below the ocean’s surface and you are soon confronted by forms of life that could not seem more foreign to our own: sea sponges, soft corals, and serpulid worms, whose rooted bodies, intricate geometry, and flower-like appendages are more reminiscent of plant life or even architecture than anything recognizably animal. Yet these creatures are our cousins. As fellow members of the animal kingdom — the Metazoa— they can teach us much about the evolutionary origins of not only our bodies, but also our minds.

It all started when Jan Louch, assistant librarian at the Douglas County Public Library in Carson Valley, Nevada, and a coworker acquired two Scottish fold cats to keep mice away from the town's new library.

It all started when Georgie, hardly more than a wisp of thistledown, discovered she could jump down twelve steps in two big graceful bounds. Next, to her great delight, she learned that jumping from the porch and floating as high as the rooftop was possible too. So when the mysterious Canada goose appeared at her window one night it seemed only natural to climb onto his back and go off with him to learn how to really fly. But no one wants Georgie flying.
