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.
In MAVEN's first few weeks of instrument testing at the Red Planet, scientists have already created some of the most complete maps of atomic hydrogen, oxygen, carbon and ozone in the Martian atmosphere ever made. One of MAVEN's instruments even collected data as energetic particles blasted out by a massive solar eruption made it to Mars.
