No one likes seeing cigarette butts strewn about city streets. No one, that is, except maybe urban birds. New research shows bird nests that incorporated cigarette butts may be repelling unwanted parasites. It turns out the deadly chemicals contained in cigarettes may provide a useful service for birds. Based on known bird behaviors, it's also possible that birds are seeking out cigarette butts to put in their nests to repel pests.
The extremely exclusive list of prehistoric creatures that are still alive and kicking just got a little bigger. Based on creatures like the horseshoe crab and the crocodile, known for evolving to their modern forms millions of year ago, you might expect the new addition to be reptilian or some deep-sea creature. You'd probably never even think about the majestic flamingo, which scientists believe may have been around over 18 million years ago.
