Forty life science exhibitors from across Michigan showed off their innovations April 19 at the West Michigan Science & Technology Initiative's fourth annual Life Science Business Showcase at the Urban Institute for Contemporary Arts. Local exhibitors included the Van Andel Institute, Avalon Laboratories, ClinXus, DornerWorks, Autocam Medical and the Michigan State University College of Human Medicine. Besides getting a glimpse of the future of medical technology, the nearly 300 people who attended the event viewed a display of the medical technology of the past. Below left, Christian G. Carron from the Public Museum is shown with a Renu-Life Violet Ray Generator, which was also referred to as a "quack" machine. Violet ray machines were believed to cure respiratory ailments when the patient inhaled the light, sparks and ozone they created.
