Scientists discover a surprising tradeoff in coral growth linked to the symbiotic algae they host. The research sheds light on the delicate balance that corals strike in adapting to rising ocean temperatures.

Corals derive much of their energy from the algae living within their soft tissue, and it appears that some symbiotic algae species help corals withstand warmer water better than others.

In a joint study, scientists found alarming concentrations of PFAS chemicals in Victoria’s critically endangered Burrunan dolphins. 

These chemicals, widely used in food packaging, firefighting foam and non-stick cookware, are sometimes called “forever chemicals” as they almost never break down in the environment.
