Joint Genome Institute Sheds Light on How Polar Algae Cope with Cold

Researchers studied Antarctic alga and microalgal communities across the globe, finding that polar algae rely on the nutrient zinc to photosynthesize and thrive. Frigid Antarctic waters harbor high levels of this trace metal, but climate change could shift nutrient concentrations. https://jgi.doe.gov/polar-phytoplankton-need-zinc-to-cope-with-the-cold/
