It's Vice's turn to have fun with a new study on mammal defecation provided by School of Biological Sciences associate professor David L. Hu's lab. The study found that despite a wide range of sizes in bodies and feces, most healthy mammals poop at the same rate. There is one telling behind-the-scenes detail: study co-author Patricia Yang says her team promised other graduate students sharing the lab not to bring their animal dropping samples from the Atlanta Zoo into the lab until after 5 p.m. because of the smell. Hu is also an adjunct associate professor in the School of Physics and an associate professor in the George W. Woodruff School of Mechanical Engineering. Yang is a Ph.D. student in the Woodruff School of Mechanical Engineering.
