The annual Duke Marine Lab Open House had exceptional attendance this year as it coincided with alumni weekend and a visit from Duke University President Vincent Price. Johnson Lab members hosted two stations at Open House on the sunny July afternoon. One station showcased the open raceway ponds, a feature of the DOE-funded large-scale algae cultivation project. Visitors were even invited to enter a rubber duck race, cheering for their small plastic toy as it rounded the bend of the raceway pond. Another station taught visitors about the diversity and lifestyles of the algae we research in lab. President Price even peered into a microscope to watch Tetraselmis cells whip around using their tail-like flagella. More photos from the weekend can be viewed on Duke’s Nicholas School news page.
