Warming oceans can break an important relationship: how corals and their relatives are controlled by their algae to look for the light. The discovery can inform efforts to save coral reefs, which in turn would benefit biodiversity and the human economy too!
In 10 seconds? A discovery into how coral-like sea creatures sense light can explain why coral reefs get into mortal danger when they are "bleached" due to warming waters or acidity. It also can direct scientists to a solution that can make the coral reefs – the rainforests of the seas – more resilient.
