Et internationalt forskerhold med danske forskere i spidsen har fundet en ny og ekstra forklaring på, hvorfor koraller lider i varmere havvand som følge af de menneskeskabte klimaforandringer politiken.dk/del/XQpN8cAHR7n…

Our findings reveal a hidden tipping point in coral survival: corals may begin to suffocate internally before or alongside bleaching These process occur in a water layer <1mm tick, easy to miss in conventional measurements but potentially critical for understanding coral health

At higher temperatures, cilia coordination stops. Microscopic flows collapse, oxygen transport slows, and oxygen levels inside the coral drop to critical levels Using high-speed microscopy, oxygen imaging and flow measurements we directly visualize flow and oxygen around corals

But the benefit doesn’t last. As temperatures rise further, these flows begin recirculating oxygen poor water near the coral surface, while coral oxygen demand keeps increasing.

Under moderate warming, corals initially cope as their cilia starts to beat faster, essentially creating stronger swirls and temporarily improving oxygen transport. This mechanism is particularly important at night when both the coral and symbiotic algae consume oxygen.

Corals 🪸 are covered with tiny hair-like structures called cilia. Their synchronized beating creates microscopic swirling flows that act like a natural ventilation system, helping transport oxygen around the coral tissue.

Coral reefs are increasingly threaten by marine heatwaves, but what pushes corals past their breaking point? New in @ScienceAdvances: we found that corals can lose the microscopic system that helps move oxygen around their tissues during heat stress 🪸 science.org/doi/10.1126/scia…

New research finds that heat stress can disrupt and eventually destroy corals’ cilia-based ventilation systems. scim.ag/3RCKBcp

I am thrilled to receive a Future Fellowship from @arc_gov_au. The project, "Understanding the role of microscale fluid dynamics in biology", aims to develop novel mathematical models and experimental tools for investigating microscopic fluid flows in biology. @SciMelb @UniMelb
