Stanford scientists discover method to reverse coral bleaching via physical contact

coral bleaching reef restoration symbiotic algae marine biology climate change

Researchers at Stanford University have discovered a potential method to reverse coral bleaching through direct physical contact between bleached and healthy coral fragments. The study, published in Science Advances, was inspired by a laboratory observation where two coral fragments from the same colony—one healthy and one bleached—accidentally touched, causing color to return to the bleached specimen.

In controlled experiments using the species Pocillopora damicornis, scientists found that when bleached fragments were placed in direct contact with healthy clones, they fully recovered within seven weeks. Microscopic analysis revealed that the corals fuse their tissues, creating tiny channels that allow for the transfer of beneficial algal symbionts and essential nutrients from the healthy coral to the bleached one.

Conversely, bleached fragments that were kept separate from healthy clones, even with only a few millimeters of distance, failed to recover and subsequently died. This biological mechanism offers a promising new avenue for coral reef restoration efforts as rising ocean temperatures continue to drive more frequent and severe bleaching events globally.
