Scientists map 110 quadrillion kilometers of underground fungi (opens in new tab)

Scientists have produced the first global map of arbuscular mycorrhizal fungi, underground networks that attach to plant roots and send fine filaments through soil. The research, published in Science on June 11, estimated that those filaments stretch about 109 to 110 quadrillion kilometers through topsoil; Folha's Portuguese-language version of a New York Times report cited 109 quadrillion kilometers, while ZME Science cited about 110 quadrillion kilometers. The fungi help plants obtain water...
