Scientists develop sunscreen made from pollen that doesn’t harm corals

Scientists have invented a pollen-based sunscreen, which their results suggest is as effective in blocking harmful ultraviolet rays as sunscreens containing chemicals that contribute to coral bleaching and pollution in oceans. In a recently published study, the researchers also showed their pollen sunscreen doesn’t harm corals. They added 1 milliliter (0.034 ounces) of both their pollen-based and a commercial sunscreen to separate 10-liter (2.6-gallon) seawater tanks with healthy coral for 60 days. The commercial sunscreen caused coral bleaching in two days and coral death in six days, but the pollen sunscreen gel had no impact on corals, which remained healthy for the duration of the experiment. “We wanted to develop an affordable and effective natural sunscreen that is non-allergenic to
