Under the right conditions, duckweed essentially farms itself. Wastewater, ponds, puddles, swamps—you name it. If there’s enough sunlight and carbon dioxide, the aquatic plant can grow freely. But that’s not all that makes it intriguing. Packed inside duckweed’s tiny fronds is enormous potential as a soil enricher, a fuel source, protein-rich foods, and more. New findings at Cold Spring Harbor Laboratory (CSHL) could help bring all that potential to life. The research is published in the journal Current Biology.
