It's been millions of years since T. rex took its last breath, but a team led by Ohio University scientists is breathing life back into dinosaurs using high-powered computer simulations to model airflow through dinosaur snouts. The research has important implications for how dinosaurs used their noses to not only breathe but to enhance the sense of smell and cool their brains.

Now a nearly complete skeleton of a prehistoric teenage girl, newly discovered in an underwater cave in the Yucatán Peninsula, establishes a clear link between the ancient and modern peoples, scientists say.
