Scientists map 68 quadrillion miles of underground fungi (opens in new tab)

Researchers published the first global maps of arbuscular mycorrhizal fungi, estimating that Earth’s topsoil contains about 110 quadrillion kilometers, or 68 quadrillion miles, of fungal hyphae. The study, published in Science, examined fungal networks that partner with plant roots and help circulate water and nutrients while moving carbon into soils. ScienceDaily, citing the Society for the Protection of Underground Networks, said the networks move about 4 billion tons of carbon dioxide into...
