Climate warming can slow how tree roots feed soil microbes
A plant's roots do much of their work out of sight, pulling in water and nutrients and holding the plant in place. That makes it hard to see how plants respond when conditions underground change, and how a warming climate affects them. New Dartmouth-led studies look at the strate

Light and ultrasound reveal renewable routes to compounds for pharmaceutical research
Sustainable packaging is only the beginning. What a medicine is made from—and how its ingredients are produced—matters just as much. Yet the synthesis of compounds for pharmaceutical research can still depend on fossil feedstocks, high temperatures, strong oxidants and metals tha
