AbstractMany single-celled organisms and specialized cell types can surprisingly achieve speed and acceleration significantly faster than multicellular counterparts. These remarkable cellular machines must integrate energy storage and amplification in actuation, latches for triggered release, and energy dissipation without failure - all implemented in macro-molecular assemblies inside a single cell.

Wildfires have become an emerging issue of natural disasters in the U.S. For example, the 2023 Hawaii Maui Island Wildfire claimed more than 100 lives and destroyed almost all buildings on the island.

AbstractCellular systems are known to exhibit some of the fastest movements in biology - but little is known as to how single cells can dissipate this energy rapidly and adapt to such large accelerations without disrupting internal architecture. To address this, we investigate Spirostomum ambiguum - a giant cell (1-4 mm in length) well-known to exhibit ultrafast contractions (50% of body length) within 5 msec with a peak acceleration of 15g.
