Cell phones outnumber people globally and they have become an important conduit through which we interact with our world, both personally and professionally. Day or night, it’s rare that our cell phone is not by our side, and yet it’s likely that you’ve been told to do precisely the opposite, due to concerns that cell phones might increase your risk of developing cancer. These concerns are partly grounded in the decisions of health authorities, including the classification of the electromagnetic fields emitted by cell phones as “possibly carcinogenic to humans” by the International Agency for Research on Cancer (IARC). Whether cell phones put our health at risk is an epidemiologic question that has been hotly debated for well over a decade. In this episode, host Bryan James is joined by Arijit Nandi and special guest Dr. David Savitz, a Professor of Epidemiology at Brown University, to distill this evidence and discuss some of the most recent recommendations regarding the health effects of cell phone use.

Drs. Justin Lessler from Johns Hopkins Bloomberg School of Public Health and Michael Mina from the Harvard School of Public Heath are back for a fourth episode to discuss the coronavirus pandemic with host Bryan James. Between our first podcast in early February 2020 and this recording, the pandemic has grown from 11 cases of COVID-19 in the US to over 1.3 million known cases and 84 thousand deaths in the US. After 2 months of shelter-in-place lockdown measures throughout most of the country, many states and cities are beginning to reopen their economies, raising concerns of a second wave of the pandemic. This discussion focuses on how to reopen the country safely; the significance of both virology and serology testing for surveillance; and some helpful advice on how to keep yourself and your family safe during the pandemic.

Depression and anxiety disorders remain among the most common and destabilizing health conditions worldwide. As the COVID-19 epidemic progresses, mental health has emerged as a principal concern, given the increase in social isolation, trauma exposure, and grief and bereavement, among other exposures. Today, Bryan James hosts a discussion with we talk with Katheleen Merikangas, Senior Investigator and Chief of the Genetic Epidemiology Research Branch in the Intramural Research Program at the National Institution on Mental Health, and Kerry Keyes Associate Professor from the Mailman School of Public Health at Columbia University, for a discussion of depression and anxiety – what these concepts mean, how and when they are clinically useful, and how we anticipate that COVID-19 will change the landscape of psychiatric diagnosis and treatment.

The coronavirus outbreak is now a global pandemic and the US is ground zero for the COVID-19 crisis. Drs. Justin Lessler from Johns Hopkins Bloomberg School of Public Health and Michael Mina from the Harvard T.H. Chan School of Public Heath are back to discuss the latest developments with host Bryan James. They address whether social distancing is helping to “flatten the curve” and why we have turned to more drastic measures such as work-from-home orders and school closings to really drop “the hammer” on the spread of the virus, as well as where we are at with a testing and masks. How long do the experts think we need to continue these mitigation measures, and do we have a plan for what to do when they end to prevent a second peak?

As the new year approaches, many people (epidemiologists included!) will resolve to begin exercising more. Making a renewed commitment to exercise is among the most common New Year’s resolutions. Although almost everyone knows they should be exercising, there is a lot of confusion about how much exercise we really need to stay healthy. Does the amount or type of exercise you need depend on whether you’re exercising to lose weight or exercising to stay healthy? Should you be adding a fitness tracker to your gift list? Are you ever ‘too old’ to lift weights? In this episode, new host Bryan James is joined by Hailey Banack to explore these, and other, interesting topics with physical activity expert Dr. Peter Katzmarzyk of the Pennington Biomedical Research Center.
