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 ...

Zhao's lab has previously created models of the rat and human nose to study air flow patterns, but the high-resolution cat model and simulation experiments are his most complicated to date, based ...

However, direct visualization of air flow patterns in in-vitro models with complex geometrical structures is a big challenge.

The pattern supporting our more-or-less continuous flow of polar air has broken down and is shifting to one favoring a stream of mild, Pacific air.
