What Works? Sophie Scott, UCL PALS Prof Sophie Scott, Director of the Institute of Cognitive Neuroscience at University College London, discusses life and science and careers with her colleagues from the Division of Psychology and Language Sciences at UCL, and beyond. The aim of the show is to highlight some amazing scientists, and explore their journeys through science and life, and find out what works for them. Lynne's Podcast Lynne August MD Dr. A offers her interpretations and applications of Dr. Revici’s profound research at DrRevici.com and the Revici Journal. Dr. Revici was arguably fifty to one hundred years ahead of his time in his application of quantum physics to medical sciences. As a once-aspiring physicist, this alone propelled Dr. A to Dr. Revici. As a physician, she felt compelled, and in some palpable way responsible, to understand Dr. Revici’s ability to control pain and achieve remissions in terminal cancer patients with his non-toxic “guided chemotherapy”, even many cancers that conventional therapy failed to control. Most of the time his questions and solutions were as unprecedented as they were effective. While Dr. Revici was primarily focused on cancer, Dr. A’s research and therapeutics to prevent and treat all chronic and degenerative disease can transform 21st century medicine.
