PBO launched another working group in the NC Mountains, focusing on cross-disciplinary written communication. We also enjoyed a stellar lecture by Prof. Chuan-Hua Chen (Duke U.) about the connections between biology and engineering through systems such as fungal ballistospores and jumping droplets. We are grateful to Duke University's Intellectual Community Planning Grant and the Blumenthal Foundation's financial support of our work at the WildAcres Retreat facility.
