 Fingerprints & Firearms (103)

Since the early 1900s, fingerprint detection and analysis has been one the most common and important forms of crime scene forensic investigation.  In fact, more crimes have been solved through the use of fingerprints than any other evidence.  The use of firearm evidence will also be discussed.  You will learn how these types of evidence were used to solve some specific cases, including some local ones.  The class will be led by Elaine Dougherty, a Forensic Scientist with the Michigan State Police Bridgeport Lab who is also an adjunct professor for the SVSU criminal justice program.  Please note that this class may include some graphic photographs.

Plumbing the Mysteries of Microbes (106)

Much interest has recently been generated by the discovery of planets orbiting stars far beyond the eight planets of our own solar system and by the intriguing possibility of life on some of those exoplanets.  However, mysteries at the macrocosmic level are not the only ones to grab and hold our attention.  Right here on Earth, by focusing on life viewed under the microscope, scientific research and the newest technologies have revealed mysteries at the microscopic level equally as profound – challenging human understanding and demanding further exploration.  This class, facilitated by OLLI member and retired science teacher, Bob Enszer, will consider the world of microbes and their relationships to humankind.  We will investigate the variety of microbes in the invisible realm, the saga of germ theory in human history, the arms race between ourselves and microbes, the strategies that microbes use to survive and thrive, the human combative immune system, microbes as weapons of war, and microbes as nature’s allies.
