Healing bleached coral by touch
Where it stands as of Oct 18, 2026
Stanford researchers reported in Science Advances that bleached coral fragments touching healthy clones of the same colony recovered fully in seven weeks, with tissue recovery starting in three days, while fragments held a few millimeters apart died. The work was done on fragments in a tank, between genetically identical clones. Whether it can work in a nursery or on an open reef is not known.

The Bright Side reported more detail on the Science Advances experiment: Danny Collins, a PhD student in Stephen Palumbi's lab, ran ten pairs of a healthy and a bleached fragment cut from the same animal. All five touching pairs recovered and all five pairs held a few millimetres apart died. Michael Sweet at the University of Derby noted that aquarists already knew algae can move between corals, and said what is new is a controlled paper.

Good News Network reported that Stanford researchers led by Danny Collins and Steve Palumbi healed bleached coral fragments in seven weeks, the fastest documented recovery, by pressing them against healthy clones of the same colony so that tissues fused and the healthy coral's algae flowed across. Fragments in touching pairs recovered fully, and those without contact died.
