Ticks sucked the blood of feathered dinosaurs some 99 million years ago, a new study suggests.

Feathered dinosaurs apparently were among the possible creatures on the menu.

When it comes to the extinction of modern animal species, humans usually end up taking the rap.

The traditional view of the disappearance of the Tasmanian tiger is no different. It follows a well-worn indictment: After the first humans began arriving in Australia (by recent estimates) some 18,000 years ago, the dog-like predatory marsupial began to disappear.

The U.S. Department of Transportation released a statement last week announcing it would withdraw a proposed rule that would force airlines to disclose baggage and other fees at the time of ticket purchase.
