Description
Heta Mattila and colleagues compare how two seaweeds handle harsh light in a 2026 study. Green macroalgae differ in whether they can switch on a fast safety valve that sheds excess light energy as heat. One alga here lacks that fast valve, while a look-alike relative has it.
Both algae faced steady and flickering strong light, and damage to their light-harvesting system was tracked. Damage rates matched between light patterns and between the two algae. The alga without the fast valve recovered more slowly and moved energy along more slowly under strong light, while its relative sped up. A drug that blocks the safety valve changed the picture further. The authors read the slower recovery as control, not extra harm.
