Stanford researchers found that one week touching a healthy Pocillopora damicornis fragment started full recovery in bleached ones. The tests used fragments in lab tanks, so whether the method could rescue wild reef corals is still open.

Finger coral from cooler Ulupau withstood more lab heat than Kaneohe finger coral or either bay's rice coral
Two Hawaiian reef corals both showed lab bleaching thresholds above NOAA's 4-degree-heating-week level, Florida Atlantic University researchers report. A tolerance score from one coral population cannot be assumed to hold for another species or bay.

Healthy-reef recordings pull coral larvae onto the structures nearest the speaker
Of 37 artificial structures placed in Kane'ohe Bay, Scripps-led trials found coral larvae settled most on those nearest a speaker playing healthy-reef sound. The result puts sound beside living coatings and 3D-printed surfaces as a restoration tool, so far tested in a single Hawaiian bay.

Diseased corals were nearly four times as likely to die in the Florida Keys' 2023 heat wave
University of Georgia researchers found diseased Florida Keys corals were nearly four times as likely as healthy ones to die in the 2023 heat wave. The authors argue cleaner local water would therefore save coral, a step the reported data support only indirectly, through disease.

Nova Southeastern researchers who cut light by 60% over Florida Keys brain corals in 2024 saw them bleach less than 20 unshaded controls. The summer killed no coral in either group, so the result supports shading as short-term protection for a few chosen colonies.

Woods Hole broadcasts healthy-reef sounds to draw coral larvae onto damaged Caribbean reefs
Woods Hole researchers are playing healthy-reef sounds to Caribbean coral larvae as hard coral cover for 2020-2024 sits 9.5% below its 1980-2009 level. Larvae they draw in will meet hotter water in 2027, and no settlement counts have been reported.

Tamil Nadu sinks 8,500 reef modules to slow the erosion of Kariyachalli Island
Tamil Nadu is lowering about 8,500 artificial reef modules around Kariyachalli, an island that has shrunk from 20.85 to 3.14 hectares since 1969. The evidence that the method works comes from one nearby island whose recovery was reported without figures, so Kariyachalli's own shoreline is the real test.

Twenty colonies give Ningaloo its first spawning baseline for two Porites corals
Curtin University researchers sampled 20 Ningaloo Reef colonies and found two Porites species preparing to spawn in the reef's early fall mass spawning. That gives restoration crews a collection date, though proving reefs reproduce after heat waves also needs egg and sperm counts.

Killed Vibrio cells primed Red Sea corals to resist a later heat-plus-infection challenge
Corals have no adaptive immune system and the KAUST team doubted priming would work. Fragments dosed with chemically killed Vibrio coralliilyticus still held up better when heat and live infection arrived together.
