Worms of Endearment

Earthworms may be small, limbless, and blind but, as Darwin observed nearly 150 years ago, they play a critical role in soil ecology. Darwin’s 19th century insights about the slimy invertebrates are far-reaching, serving as the backbone of modern ecology as a whole. In recent years, scientists are putting their ears to the ground, listening to worms to monitor soil health. Meanwhile, laboratory studies on another kind of worms—flatworms—are providing insights about how memories are stored, and how stem cells self-renew. We get our hands dirty for this episode about the biology and ecology of worms.
