Seeking Understanding: John Walton
If you have ever heard of “free radicals,” you know something about the work of Dr. John Walton, a professor of chemistry at St. Andrews University in Scotland. Dr. Walton’s work concentrates not only on the destructive reactions that come to mind when most people think of free radicals, but also on the positive effects of these fascinating chemicals. He also studies the potential of free radicals in industrial and environmental chemistry. What we know about free radicals because of the work of Dr. Walton and other chemists can also inform our understanding of how life came into being. Based on his life as a scientist and the research he has done, what does Dr. Walton believe to be the most reasonable explanation of life’s origin? This is the subject of this 22:30 episode of the Seeking Understanding series.
Design at the Molecular Level
Scientists are just beginning to understand the structure and function of minute machines that are essential for life. Inside cells, these submicroscopic motors, generators and other machines operate by the same principles as the machines we are familiar with, only at much higher efficiency and within incredibly tight tolerances. What best accounts for these engineering marvels? Shelley Quinn and Tim Standish, PhD
