The paradox of today's global food system is that food insecurity or obesity threaten the health and welfare of half the world's population. Underlying these problems is an overabundant and overly competitive food system in which companies are forced to expand market channels to meet corporate growth targets. The contradiction between the goals of public health and food corporations has led to a large and growing food movement in the United States, which seeks policy changes to promote healthier and more environmentally sound food choices. Marion Nestle considers the cultural, economic, and institutional factors that influence food policies and choices, and the balance between individual and societal responsibility for those choices.

Starting with a fascinating history of diving, Dr. Stephen Hoffman explores various causes, effects, and symptoms of diving accidents and complications. Recorded on 05/10/2017.

Michael Green, neuroscientist and professor of psychiatry and biobehavioral sciences at UCLA, has been fascinated with the human brain, behavior and mental illness since his undergraduate days. In particular, his research focuses on schizophrenia, a chronic brain disorder that affects about 1 percent of the population. In this UCLA Faculty Research Lecture, he describes how his lab uses discoveries in psychology and social neuroscience about normal brain functioning to inform his schizophrenia research. And now, Green and his colleagues are moving into new territory, studying the causes of social isolation among people who do not have schizophrenia. You'll learn about the tools they use such as functional MRI, that measures and maps brain activity, and EEG, that detects electrical activity in the brain, and how they do research to answer questions about social isolation in the general public.

Clinical psychologist Erik Groessl talks about research showing the value of yoga in reducing pain, improving physical function and overcoming opioid addiction in military veterans, among other patients, in this conversation with Paul J. Mills of UC San Diego.

Dr. Leigh Kimberg, Program Director for PRIME-US for students committed to working with urban undeserved communities, discusses the treatment framework that involves understanding, recognizing and responding to effects of all types of trauma in patient care. Recorded on 12/05/2017.

Even after medical school, learning for doctors continues in the form of residency, fellowship and lifelong learning. Dr. Robert Baron, Associate Dean for Graduate and Continuing Medical Education at UCSF, explains how doctors become specialists and then stay current throughout their careers. Recorded on 11/29/2017.

The Last Gift study aims to understand where and how HIV hides in the human body when a person with HIV is taking HIV medications. The Last Gift study tackles these aims by studying people with HIV who are terminally ill from a disease other than HIV, like cancer, ALS, or heart disease. The study follows these volunteers with regular blood draws before the person dies and then examines multiple tissues throughout their bodies after death. From these samples, investigators hope to understand how HIV remains hidden from both the person's immune system and from current HIV therapy. Results from these studies are designed to help develop ways to clear these reservoirs with future therapies. Dr. Davey Smith, Professor of Medicine and Chief of Infectious Diseases and Global Public Health at UCSD discusses the study and its medical and ethical implications.
