Biosphere-Atmosphere Interactions (BAI)

The research of the BAI group is designed to advance understanding of global biosphere - atmosphere interactions and to predict the response of the earth system to future perturbations. This is being accomplished through multidisciplinary field, laboratory and modeling studies of the processes controlling these interactions on various scales (e.g., leaf to canopy to landscape to global).

Plants Make Their Own Painkillers

Walnut trees respond to stress by producing significant amounts of a chemical form of aspirin, scientists have discovered: Thomas Karl, Alex Guenther, Andrew Turnipseed, Edward Patton, & Kolby Jardine. In the News:

- Walnut Trees Emit Aspirin-Like Chemical to Deal With Stress (NSF)
- Plants Make Own Painkillers (LiveScience)
- Plants make their own version of aspirin, researchers find (Los Angeles Times)
- Stressed plants release aspirin-like chemical (Reuters)
