Amino acids that can block ultraviolet light are commonly harvested from algae, and used in cosmetics like Helioguard 365. Now researchers at Harvard have discovered the genes responsible for producing these materials and, with a little gene tweaking, managed get E. coli bacteria to produce them too.
