For podcast listeners in the Emory biomedical research community, Behind the Microscope is a must-follow. It is produced by four students in Emory’s MD/PhD program: Carey Jansen, Joe Behnke, Michael Sayegh and Bejan Saeedi. They’re focused on career issues such as mentorship and grant strategy rather than the science itself (thus, complementary to Lab Land).
In their list of interviewees so far, they lean toward their fellow “double docs.” Since starting off in October, they’ve talked with Anita Corbett, Brian Robinson, Sean Stowell, Stefi Barbian and Steven Sloan (MD/PhDs underlined). Here are the Apple and Google podcast listings; episodes are also available on platforms such as Anchor.fm.

Consider this: Alzheimerâ€™s is a uniquely human disorder. But why? Why donâ€™t nonhuman primates, such as monkeys, get Alzheimerâ€™s disease. Monkeys form the senile plaques that are identical to the plaques found in humans. So do other animals.
â€œYet, despite the fact that nonhuman primates make this protein that we know is very important in the pathogenesis of Alzheimerâ€™s disease, they donâ€™t develop the full disease,â€ says Lary Walker, PhD. Walker is an associate professor at Yerkes National Primate Research Center.
â€œThey donâ€™t develop the tangles we associate with Alzheimerâ€™s disease, the neuronal loss, the shrinkage of the brain, and they donâ€™t get demented in the sense that humans do,â€ says Walker.
When our bodies make a protein, the protein tends to fold into a functional form. But when it comes to Alzheimerâ€™s disease, some proteins misfold, becoming sticky and then combining with one another. In their collective form, the proteins can then form plaques or tangles, the two types of lesions associated with Alzheimerâ€™s disease.
And for some unknown reason, people who have plaques usually go on to form tangles. But people who have tangles donâ€™t always go on to form plaques. No one is sure why. But thatâ€™s what researcher Walker wants to find out.

Physicians and researchers are seeing a resurgence of micronutrient deficiencies in certain high-risk populations of children. But what exactly does that mean to those childrenâ€”right now and in the future?
For children who donâ€™t get enough micronutrients it means life-long problems, including decreased neurodevelopment and diminished cognitive abilities.
â€œMicronutrients are nutrients that are needed by the body in small quantities and are important for development, growth and sustaining life,â€ says Conrad Cole, MD, MPH, assistant professor of pediatrics in the Division of Pediatric Gastroenterology and Nutrition in Emory School of Medicine. â€œThatâ€™s why theyâ€™re called micronutrients, and the ones we commonly think about are iron, vitamin D, calcium and zinc because they all have significant importance.â€
