Tracking mosquitoes with your cellphone

Researchers at Stanford University developed a platform called Abuzz that uses cellphone recordings to track mosquito populations and distributions. The platform aims to create the world's largest network of mosquito surveillance, enabling targeted control efforts and reducing the burden of mosquito-borne diseases.

Climate solution in soil?

Stanford researchers found that managed soil can trap more carbon dioxide than previously estimated, potentially offsetting future emissions. Improving land management practices like reduced tillage and perennial crops could increase soil's carbon storage.
