An unwanted weed may soon find a surprising new purpose — dressing astronauts and soldiers. Scientists have discovered that Calotropis, a hardy, fast-growing weed often seen as a nuisance, produces silky fibers that are lightweight, durable, and resistant to harsh conditions. These natural fibers, once refined, could be used to develop high-performance textiles suitable for extreme environments, including space missions and military operations. The plant’s abundance and eco-friendly profile add to its appeal, offering a sustainable alternative to synthetic fabrics currently in use.
