Arctic Microalgae Defy Photosynthesis Limits
2025-02-06
New research reveals Arctic microalgae can photosynthesize under extremely low light conditions, nearing the theoretical minimum. Researchers observed algae growth shortly after the polar night, indicating they maintain low-power operation during darkness and rapidly activate photosynthesis when light returns. This finding could reshape our understanding of Arctic ecosystems and deep-sea life, suggesting the productive ocean zone might extend deeper than previously thought.
