Different types of airflow patterns in animal lungs. Mammals (top left) have a tidal airflow pattern where air moves to-and-fro through a branching network of bronchi. Birds (top right) have looping ...

Birds and mammals are on extreme ends of the airflow spectrum. Mammals inhale oxygen-rich air and they exhale depleted air, exhibiting a so-called tidal flow pattern. In contrast, bird breath travels ...

Take a deep breath in. Slowly let it out. You have just participated in one of the most profound evolutionary revolutions on Earth--breathing air on land. It's unclear how the first vertebrates ...

The Hadley circulation is a key atmospheric circulation pattern in the tropics. It helps even out the temperature between the equator and the poles by moving energy and momentum toward higher ...

If you've ever wondered why some folks never catch the office or school cold, where they're sitting might be keeping them from the path of pathogens, according to new UBC Okanagan research. The ...

A new study uses computer simulations to track airflows inside a car's passenger cabin, providing potential strategies -- some of them counterintuitive -- for reducing the risk of transmitting ...
