An international team of researchers has identified molecules in the earthworm gut that enable digestion of polyphenol-rich plant material, such as fallen leaves. Drilodefensin distribution in an earthworm: schematic 3D model based on micro-computed tomography integrated with imaging mass spectrometry data. The color scale represents the relative abundance of the compound. Image credit: Manuel Liebeke et al. Earthworms are responsible for returning...
