MSU discoveries upend traditional thinking about how plants make certain compounds

EAST LANSING, Mich. Michigan State University plant scientists have identified two new genes and two new enzymes in tomato plants; those findings led them to discover that the plants were making monoterpenes, compounds that help give tomato leaves their distinctive smell, in a way that flies in t...

'No time to lose' to start thinking sustainability

As director of the University of Oregon's Climate Leadership Initiative, the need to address human contributions to global warming is a no-brainer that Bob Doppelt says in his new book requires a mindset tuned into "The Power of Sustainable Thinking." The 240-page book published by London-based...
