Rats Say: Manhattan Rules! If you leave it up to the rats, New York City beats New Orleans any day. This surprising finding comes from new research by Tel Aviv University zoologists and geographers, who are working together to invent a novel way to test urban designers' city plans. Instead of using humans as guinea pigs, the scientists went to their nearby zoo and enlisted lab rats to determine the functionality of theoretical and existing plans. They've already tried their theory in the...
