SC 209: Topics in Science. Class presentation available.

This class is a collection of one-hour presentations on science topics that are of interest to the general public, intended to be in plain English and easily understood.

Monday, November 2:  The Obesity Epidemic

The brain plays an integral role in determining our diets, whether they are healthful or filled with empty calories.  Poor diets have much to do with the expanding obesity epidemic seen many places in the world, including the U.S.  Pitfalls of an unhealthy diet and recommendations for turning it into a healthy one will be covered.

Healthcare by Smartphone

Smartphones have altered our lives and medicalized smartphones are next. The result will be an increasingly powerful tool that will reduce the use of doctors, cut costs and speed the pace of care. We will be able to diagnose ear infections, track heart rhythms, find genetic markers, and even monitor mental health. The information will go directly to your doctor’s office. You will probably still be able to see your physician but the relationship may be radically altered.

Presenter:  Jerry Florman, retired pharmacist and OLLI Science Committee member.

Presenter:  Ed Garr, M.D., is a retired orthopedic specialist and OLLI Science Committee member.

Monday, November 9: Microbiology in Forensics

Knowledge of the human microbiome and forensic science are now merging into the new discipline of bacterial forensics. A TV drama recently portrayed the analysis of microbes on a keyboard transferred from a suspect’s skin as evidence of criminal activity. Research on insect activity in the soil at crime sites has been used in forensic analysis.  From a systems dynamics point of view, information gleaned from a bacterial population is potentially much richer. Does everyone have a microbial fingerprint?

Presenter:  Vern Roohk, Ph.D.,

Physiology and Biochemistry, UC Davis.  Vern is an OLLI Science Committee member and a biomedical consultant specializing in medical device evaluation.

Detecting Gravitational Radiation from the Beginning of the Universe

Professor Abazajian will update us on new results to detect polarized light from the cosmic microwave background that contains evidence of quantum fluctuations in matter density from before the Big Bang. The fluctuations produce gravitational radiation that polarize the light, and were the source for the condensations of matter into today’s galaxies, galaxy clusters, and walls of cosmic matter.

Presenter:  Kevork Abazajian, Ph.D., UCI Department of Physics and Astronomy.
