Scientists in Australia say they have found a way to help coral reefs fight the devastating effects of bleaching by making them more heat-resistant. Rising sea temperatures make corals expel tiny algae which live inside them. This turns the corals white and effectively starves them.
In response, researchers have developed a lab-grown strain of microalgae which is more tolerant to heat.
When injected back into the coral, the algae can handle warmer water better.
The researchers believe their findings may help in the effort to restore coral reefs, which they say are “suffering mass mortalities from marine heatwaves”.
The team made the coral – which is a type of animal, a marine invertebrate – more tolerant to temperature-induced bleaching by bolstering the heat tolerance of its microalgal s...
