⚡A study found that bleached corals can recover within days when placed in contact with healthy corals.

What it means

This study reports that bleached corals—those that have lost their symbiotic algae due to stress—can recover their color and health within days when placed in direct physical contact with a healthy coral colony. The finding suggests that corals can rapidly exchange beneficial compounds or algae through direct contact, dramatically shortening the typical recovery timeline from weeks or months to just days.

Accuracy & sourcesSourced

The claim is based on a peer-reviewed paper published in Nature, a leading scientific journal. As a primary source, the finding carries high authority, though the specific experimental design, sample size, and reproducibility details are not available from the headline alone.

How new

This appears to be genuinely new research, with no indication of recirculation or older material.
