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 thrived ...

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 ...

A new study of airflow patterns inside a car's passenger cabin offers some suggestions for potentially reducing the risk of COVID-19 transmission while sharing rides with others. The study, by a team ...

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 single-pass airflow pattern, or reduced pass airflow patterns, strive to minimize the airborne particulates in the space to reduce the risk of health care-acquired infections. Displacement ...

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 ...

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 ...
