Schwalm III, Varsha Raghavan, Natasha A. Barry, Andrew L. Goodman, and Eduardo A. Groisman, which was first published December 17, 2018; 10.1073/pnas.1813780115 (Proc Natl Acad Sci USA 116:233–238).
The authors note that, in the SI Appendix, page 13, second paragraph, line 10, “1.5 M sodium hydroxide” should instead appear as “1.5 M sodium chloride.” The SI Appendix has been corrected online.
