Scientists map Earth's 110 quadrillion-kilometer fungal network (opens in new tab)

An international research team published the first global maps of the estimated distribution and mass of arbuscular mycorrhizal fungal networks, underground hyphal systems that link with plant roots and move nutrients, water and plant-produced carbon through soils. The study estimated that the networks stretch about 110 quadrillion kilometers worldwide, nearly a billion times the Earth-to-sun distance and more than 100 quadrillion kilometers in total. The researchers used machine-learning mod...
