Speaking with Light: Tackling Pollution with Bioluminescent Indicators

Synopsis
Many marine organisms have evolved to exhibit bioluminescence putting on incredible deep sea displays of flashing lights, sparkling blooms and smoke-like clouds of shimmering blue. Inspired by this, marine biologist Dr Edith Widder has developed a way to use bioluminescent bacteria to help protect aquatic environments.

Some of the most insidious forms of modern-day pollution are not visible to the naked eye, especially those which contaminate our oceans. By mixing bioluminescent bacteria with sediment samples, Dr Widder uses these tiny organisms as bioindicators of toxins in marine and riverine environments. Using the light these sea creatures produce we are better able to reveal the source and severity of pollution in our waterways.
