Natural History
This bird likes livers, kidneys, entrails — anything it can pluck that's freshly dead. But what if you served it ... a painting?
 
A secretive, nocturnal species that lives on a remote island off the coast of Mexico had not been spotted since 1936. Scientists have concluded it is genetically distinct from mainland neighbors.
 
The Smithsonian is set to unpack something it's never had before: a rare, nearly complete Tyrannosaurus rex skeleton. It's a gift from a Montana museum that says this T. rex deserves to be famous.
 
A 325 million-year-old fossil find shows that the gill structures of modern sharks are actually quite different from their ancient ancestors.
 
Curators say they'll use the big grant from Boeing to better highlight how exploratory flight — from the Spirit of St. Louis to the <em></em>Starship Enterprise — has transformed the world.
