Cat Tales

They may have stolen many hearts-and the internet-but cats can be perplexing pets. As much cuddly and playful as they are aloof and uncaring, they've often raised the question: Did humans ever really domesticate felines? And what more can science tell us about a relationship that predates history?

Last B-24

In 1944, a smoking, battle-scarred B-24 Liberator bomber known as the Tulsamerican crashed into the choppy seas off the coast of Croatia, entombing three of its occupants under 135 feet of water. For years they were lost to the world — and their families. But in 2010, nearly seventy years after the crash, divers located the plane. And in 2017, the Department of Defense, aided by the Croatian Navy and some of the world's leading underwater archaeologists, set to work investigating the wreckage. Were the B-24s truly as dangerous as the nickname "the Flying Coffin" suggested?

Bigger Than T. rex

Almost a century ago, paleontologists found the first tantalizing hints of a monster even bigger than Tyrannosaurus Rex, perhaps the largest predator ever to walk the Earth: spectacular fossil bones from a dinosaur dubbed Spinosaurus. But the fossils were completely destroyed during a World War II Allied bombing raid, leaving only drawings, lots of questions, and a mystery: What was Spinosaurus? Now, the discovery of new bones in a Moroccan cliff face is reopening the investigation into this epic beast. What did it feed on and how? Why did it grow so big?
