DIY Filter Systems Improve Air Quality in Classrooms
Tests in university classes show that simple, low-cost systems can remove airborne particles with little disruption from fan noise.
Adding Limestone to Mississippi River Basin Farmlands Acts as a Major Carbon Sink, Study Finds
In a discovery as broad and far-reaching as the Big Muddy itself, a new, Yale-led study says farmers along the Mississippi River Basin are storing more carbon dioxide (CO2) in the soil than they are emitting when they add limestone to their fields, an agricultural practice known as “liming.”
