Insights into deadly coral bleaching could help preserve reefs: Surprising result from study of 1893 World's Fair corals

Coral reefs are stressed because of climate change. Researchers have discovered corals themselves play a role in their susceptibility to deadly coral bleaching due to the light-scattering properties of their skeletons. No one else has shown this before. Using optical technology designed for early cancer detection, the researchers discovered that reef-building corals scatter light in different ways to the symbiotic algae that feed the corals.
