Summary

Story summary

U.S. and German researchers published a Science study that coral cilia overwork in warming water.
Coral polyps use hairlike cilia to spin vortices delivering oxygen; at night cilia are the sole oxygen source.
Warmer water holds less oxygen, so cilia beat faster and consume more oxygen than corals can absorb, causing suffocation.
The study links cilia stress to coral bleaching patterns, disease outbreaks, and mass die-offs.
