An ecosystem of trees, soil, and carbon cycling
Global mapping shows arbuscular mycorrhizal fungi link to plant roots and store hundreds of megatons of carbon, revealing their critical role in the Earth’s carbon cycle and the sensitivity of these underground networks to land use.
Nigeria's security forces have freed 308 hostages abducted in recent months, including 163 from Woro in Kwara state and 145 from Niger state. The operation involved the military, police, and counter-terrorism units and is described by officials as the largest rescue carried out in a single day.
