Laura Sanders reports on neuroscience for Science News. She wrote Growth Curve, a blog about the science of raising kids, from 2013 to 2019 and continues to write about child development and parenting from time to time. She earned her Ph.D. in molecular biology from the University of Southern California in Los Angeles, where she studied the nerve cells that compel a fruit fly to perform a dazzling mating dance. Convinced that she was missing some exciting science somewhere, Laura turned her eye toward writing about brains in all shapes and forms. She holds undergraduate degrees in creative writing and biology from Vanderbilt University in Nashville, where she was a National Merit Scholar. Growth Curve, her 2012 series on consciousness and her 2013 article on the dearth of psychiatric drugs have received awards recognizing editorial excellence.
