BIOPHYSICS AND COMPUTATIONAL BIOLOGY, ENGINEERING Correction for “Biomechanics of red blood cells in human spleen and consequences for physiology and disease,” by Igor V. Pivkin, Zhangli Peng, George E. Karniadakis, Pierre A. Buffet, Ming Dao, and Subra Suresh, which appeared in issue 28, July 12, 2016, of Proc Natl Acad Sci USA (113:7804–7809; first published June 27, 2016; 10.1073/pnas.1606751113).
