Researchers Map Mycorrhizal Fungi Carbon Hotspots
Researchers from the nonprofit SPUN are using a machine-learning model (trained on 25,000 geolocated soil samples and 2.8 billion fungal DNA sequences) and 2025 field expeditions to validate predicted mycorrhizal hot spots in northern Alaska (sampled June 2025). The work links fungal biodiversity to carbon storage—fungi sequester over one-third of annual emissions—and aims to prioritize conservation of permafrost soils that store roughly 1 trillion metric tons of carbon.
Scoring Rationale
Strong peer-reviewed foundation (Nature-model) and broad ecological scope drive a high score; the piece offers actionable conservation targets and credible data. Score slightly tempered by narrative focus with limited technical ML methodology detail.
