Darling Marine Center
Betty Twarog passed away recently after several months of failing health. She was 85 years of age. Betty was credited in 1953 with discovering serotonin, a neurotransmitter hormone that plays an important part in the regulation of learning and sleep, and also has a role in affecting mood. Later in life she worked on invertebrate smooth muscle at Tufts, then Harvard, and later SUNY at Stony Brook. She retired to Maine after a distinguished career in science and, until last fall, regularly visited her office at Darling Marine Center in Walpole to share thoughts with, and mentor, younger colleagues.
