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 ...

Scientists have presented a model that elucidates the chain of physical processes driving interannual Hadley cell expansion in the Northern Hemisphere. The Hadley circulation is a key atmospheric ...

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 ...

Accounting for airflow dynamics rather than just airflow volume helped researchers measure an 85% reduction in airborne pathogens inside a working classroom. If you've ever wondered why some folks ...

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 ...
