Marine Science
Scientists have developed a revolutionary imaging technique that uncovers the intricate internal architecture of plankton, the ocean's microscopic powerhouses. Using ultrastructure expansion microscopy, researchers visualized over 200 marine species for the first time, mapping evolutionary patterns in their cellular skeletons. This work, stemming from a pandemic-era collaboration, launches a global atlas of plankton diversity.

Marine green algae have evolved a pigment called siphonein that shields their photosynthetic machinery from intense sunlight. Researchers from Osaka Metropolitan University discovered how this carotenoid efficiently quenches harmful energy states. The finding could inspire more durable solar technologies.
