While the region boasts a colorful history of pirates and shipwrecks, scientists will head there this summer seeking treasure of a different sort: beaked whales, some of the deepest diving and least known animals on Earth. The research aims to solve one of the most contentious m...

Mites that were thought to be parasites to their host wasps turn out to be bodyguards, attacking intruders.
