Ig Nobel Prize winner David Hu researches many questions that involve biology AND mathematics AND physics. And often, fluid dynamics. In this video, he confides, concisely, some of the biophysical ways that ants survive perilous, quickly-changing physical conditions:
The 2015 Ig Nobel Prize for physics was awarded to Patricia Yang [USA and TAIWAN], David Hu [USA and TAIWAN], and Jonathan Pham, Jerome Choo [USA], for testing the biological principle that nearly all mammals empty their bladders in about 21 seconds (plus or minus 13 seconds).

NOTE: David Hu will be one of the stars of the London shows on the upcoming Ig Nobel Eurotour, in March 2016.
