In 1974, he designed and built the first streamlined bicycle in the USA, which is now in the Davis Bicycle Museum. He was cofounder of the International Human Powered Vehicle Association in 1976. Kyle led bicycle design for the USA in the 1984 and 1996 Olympics. He has been a researcher and consultant on sports aerodynamics to companies such as Nike, Specialized and Bell. He has published over 100 popular and scientific articles on sport and was an editor for Cycling Science and Bicycling Magazine. Kyle designed the wheels, tires and brakes of the GM Solar Car, the Sunraycer, winner of the first World Solar Challenge and was a consultant on Paul MacCready’s human powered aircraft, the Gossamer Condor, winner of the Kremer Prize.
Chester (Chet) Kyle will speak about the bicycle, solar cars, and human powered aircrafts as a means of travel. The bicycle is a remarkably sophisticated machine, and yet it is relatively inexpensive, simple to work on and can be the basis for some fascinating yet surprisingly economic research. This lecture describes technical details of some of the cycling and sports related projects Chester Kyle has participated in since 1972.
Among the projects were: The development of high speed pedal powered bicycles that have exceeded 80mph on the level with no wind on 600 watts of human power. The design of aerodynamic time trial bicycles for hte 1984 Los Angeles and 1996 Atlanta Olympics. The development of aerodynamic "Swift" suits for Nike which were used by Olympic gold medalists in running and speed skaiting and by the winner of the Tour de France. In these sports, wind tunnel testing has been a key element in improving equipment and atheltic performance.

Dr. Street also enjoys volunteering her time to community outreach venues, such as OASIS, an active senior citizen continuing education program.
Lecture Abstract: Damage to mitochondrial DNA can impair energy production and could ultimately result in cellular and organismal dysfunction. Indeed, the consequences of mitochondrial dysfunction are exemplified by human mitochondrial diseases, induced cellular death (apoptosis), and perhaps, normal aging. Mitochondrial diseases typically manifest in tissues with high-energy requirements such as brain, heart, and skeletal muscle. Because mitochondrial diseases typically affect neuromuscular tissues, establishing an appropriate cell type in vitro system to more directly test the role of oxidative DNA damage in aging is warranted. Experiments and cell lines were designed to more directly delineate the contribution oxidative damage in mitochondrial DNA has in aging. Specifically, the working hypothesis is that mitochondrial DNA repair can be increased by targeting a DNA repair protein to the mitochondrial matrix.
Since the time these experiments were performed, the scientific community has revealed some insight in the roles the outer and inner mitochondrial membranes play in regulating the import of proteins into the mitochondrion. The quest to modulate and manipulate mitochondrial function through proteomics and genomics for therapeutic benefit still exists. Despite over 20 years of scientific inquiry into approaches to treat mitochondrial dysfunction, most of these approaches remain in their infancy. Rationally, overcoming the obstacles for targeting mitochondria could lead to the selective protection of cells in different tissues/organs and provide a "molecular handle" in alleviating mitochondrial dysfunction.
Lecture dedicated to Dr. Richard McCullough in honor of his commitment to the Division of Mathematics, Science, & Engineering at Saddleback College. Dr. McCullough served the college for more than 30 years as a Professor in the Biological Sciences Department, Dean of the MSE Division, and former Saddleback College President.

Lecture Abstract: Rattling by rattlesnakes is one of the fastest vertebrate movements and involves some of the highest contraction frequencies sustained by vertebrate muscle. Specifically, the shaker muscles in the tails of rattlesnakes can sustain contraction frequencies up to 100 Hz for minutes to hours. These features make shaker muscles an excellent system for studying the mechanisms that allow muscles to sustain intense exercise without fatiguing. In a series of projects done over several years, I studied the anatomy, physiology, and biomechanics of shaker muscles in order to understand the mechanisms that allow the muscles to sustain high-frequency contractions for long periods. Although shaker muscles use energy at high rates overall, they have a low cost per contraction because of the complex movements they produce and the biomechanical tradeoffs they make. Shaker muscles minimize the cost per contraction by exerting low forces, doing little work, and shortening very little, but not by recycling elastic strain energy. In addition, changing physiological and biomechanical constraints allow the muscles to function as they change in size and mass dramatically with growth. Together, these features allow the muscles to sustain the fast contractions necessary for sound production and self-defense without fatiguing throughout life.

Disordered eating is an unrecognized and common nutritional challenge for adolescents, young adults and their families. Disordered eating presents as a pattern of behaviors that reflect distorted attitudes and perceptions about health and eating, diet and weight control, body image and self-esteem and exercise. It may lead to or be a precursor to actual eating disorders such as anorexia nervosa and bulimia. Many young people and their families perceive that their eating and exercise regimes are part of a healthy lifestyle but they may have “crossed the line” actually into an unhealthy range unintentionally. In addition there is much pressure from peers, the media and sports, dance and other body esthetic programs which present a one-sided approach or body type as “perfection”. Often to achieve this body type, it is necessary to engage in unhealthy behaviors with nutritional restriction, use of unnecessary and sometimes harmful “supplements” and unhealthy exercise regimes. This presentation will assist the participants in recognizing what is normal and what may be harmful to one’s health and to discuss how to avoid unhealthy lifestyle choices and to embrace the exhilaration of appropriate exercise, participation in sport activities and joy of sharing food with self, friends and family.

The term “nuclear waste” excites fear and revulsion among many residents of the United States. However, it is fossil fuel waste, in the form of CO2 being pumped into our atmosphere, which will be the bigger worry. Experts point to shifting weather patterns, drought, floods, stronger storms, and stifling summer heat and ocean acidification in the future: these changes will be expensive to mitigate, and will make us all poorer. In addition, civilization relies on a steady, reliable supply of electric power for almost every aspect of modern life. We cannot rely on intermittent forms of power like solar or wind at the current time, nor can we drill up and burn even the known reserves of coal, oil and gas without dire consequences. We need nuclear power, for many reasons that I will make clear in this lecture, and we need to learn to fear the right things like disease, war, and famine rather than nuclear power plants. Future power will be ultra-safe, clean, quiet, and almost invisible. I will show you the exciting prospects for those with training in science to really make a difference in the future.
