Southfield, Mich. – “From Silent Spring to Silent Night” is the topic for Lawrence Technological University’s 2010 Walker L. Cisler Lecture, which will be delivered by Tyrone Hayes, professor of development endocrinology at the University of California, Berkeley. Hayes speaks on Tuesday, March 30, at 7:30 p.m. in the Lear Auditorium (T429) of the University Technology and Learning Center at Lawrence Tech, 21000 West Ten Mile Road, Southfield.
Lawrence Tech’s annual Walker L. Cisler Lecture is dedicated to the improvement of science education. The event is free and open to the public, and a dessert reception will follow.
The nighttime symphony of croaking frogs and toads is becoming a thing of the past, and Hayes, an internationally recognized biologist, believes he knows why. His research on atrazine, a widely used pesticide found in groundwater, local streams, and ponds, has revealed that the product is a potent endocrine disrupter that chemically castrates and feminizes male amphibians.
Atrazine also causes neural damage and hyperactivity and induces a hormonal stress response that leads to retarded growth and immune suppression, resulting in increased disease and mortality rates. Furthermore, Hayes believes it has become clear that the adverse effects of atrazine extend beyond amphibians to mammals – including humans – causing prostate and breast cancer and decreased fertility.
Hayes received his PhD in integrative biology from Berkeley and his bachelor’s degree from Harvard University.
