Episode Details

April is Earth Month, and in appreciation of the plant life all around us, we’re re-running a conversation we had with Beth Sattely last year on the future of plant chemistry. Beth reminds us that plants are more than food or pretty things to look at — they have the potential to help us fight climate change or even cancer. We hope you’ll take another listen and join us in learning more about how plants can positively impact environmental and human health.

Have a question for Russ? Send it our way in writing or via voice memo, and it might be featured on an upcoming episode. Please introduce yourself, let us know where you're listening from, and share your question. You can send questions to thefutureofeverything@stanford.edu.
