Dr. Kevin Hall — Dueling Diets Mar 02, 2021

Show notes

Nutrition is a contentious topic. It's hard to tell fact from fiction. One day eggs are good for you, the next they have too much fat. But what about the keto craze? Doesn't it say you should eat mostly fats? Fortunately, there are scientist like Dr. Kevin Hall who are working to debunk the myths and give us the real skinny on how the foods we eat affect our health. Most recently, Dr. Hall published a study that put two well-known diets head-to-head to see which led people to consume more calories.

Dr. Carlos Zarate — Ketamine to Combat Depression Jan 08, 2021

Show notes

Ketamine is often thought of as an illicit party drug—something people take for a momentary high. But it wasn't designed to be a mind-altering drug. Originally, ketamine was developed as anesthetic to relieve temporary pain. And now it seems the drug can provide solace not just from physical distress. At the NIH, Dr. Carlos Zarate is investigating how ketamine can rapidly reduce depressive symptoms in people with treatment-resistant depression or bipolar depression, for whom other options have not helped.

Drs. Heidi Kong and Ian Myles — Derm Germs: The Human Skin Microbiome Oct 07, 2020

Show notes

In nature, strategic alliances can mean the difference between life and death. For humans, such vital partnerships exist between us and the trillions of microbes we unwittingly host in and on our bodies - together called the microbiome. Dr. Heidi Kong uses genomics to uncover the microbe-host interactions taking place all over our skin. Building on her work and a growing understanding of the skin microbiome, Dr. Ian Myles has developed a bacterial spray that improves eczema, an inflammatory skin disease.

Dr. Peter Bandettini — Mr. MRI Sep 01, 2020

Show notes

Dr. Peter Bandettini spends a lot of time peering into people's heads. Not because he is clairvoyant, but because he is a biophysicist. Using functional MRI (fMRI), a revolutionary neuroimaging technique he helped pioneer in the '90s, Dr. Bandettini delves into the mysteries of the human brain. He is working to advance fMRI technology to parse out more information about the neural connections that are constantly and spontaneously active even when we think our minds are blank.

Dr. Bandettini is a principal investigator at the National Institute of Mental Health (NIMH) and the director of the Functional Magnetic Resonance Imaging Core Facility. Learn more about his work at https://irp.nih.gov/pi/peter-bandettini

Dr. Hannah Valantine — At the Heart of Diversity Jul 30, 2020

Show notes

Time and again, diversity and inclusion initiatives have proven to boost productivity and overall well-being in the workplace. But despite countless studies and although there have been significant strides in recent history, the struggle to ensure equal opportunity persists. At the NIH, the Scientific Workforce Diversity (SWD) Office is expanding recruitment and retention with Dr. Hannah Valantine as its first chief officer. She emphasizes how proper resources, mentorship, and community are essential for progress in the biomedical field.

Dr. Valantine is also a cardiologist and Senior Investigator of the Laboratory of Transplantation Genomics in the National Heart, Blood, and Lung Institute (NHLBI). Learn more about her research at https://irp.nih.gov/pi/hannah-valantine

Drs. Richard Childs and Matthew Hall — Remdesivir Therapy for COVID-19 Jun 22, 2020

Show notes

In this episode, Dr. Richard Childs, a senior investigator and Clinical Director of the National Heart, Lung, and Blood Institute (NHLBI), recounts his experience using the antiviral remdesivir to treat patients with COVID-19 in one of the early hot zones of the pandemic. He led a team sent to care for passengers on the Diamond Princess cruise ship that was held in quarantine in Yokohama, Japan at the start of the outbreak. Since then, remdesivir has continued to gain traction as a possible standard of care. Dr. Matthew Hall, biology group leader at the National Center for Advancing Translational Sciences (NCATS), explains the development of the drug and its newfound purpose in the battle against the novel coronavirus.

Dr. Kizzmekia Corbett — The Novel Coronavirus Vaccine May 21, 2020

Show notes

Perhaps now more than ever, it is undeniable how integral vaccines have become to public health. Vaccines protect us from a whole host of infectious diseases, including chickenpox, measles and the seasonal flu. With a new threat at hand, scientists at the NIH swiftly developed a vaccine candidate against the novel coronavirus that causes COVID-19. The pre-clinical effort was driven in part by Dr. Kizzmekia Corbett.

Dr. Corbett is a viral immunologist and research fellow in the Vaccine Research Center (VRC) of the National Institute of Allergy and Infectious Diseases (NIAID). Learn more about the work taking place at the VRC at https://www.niaid.nih.gov/about/vrc

Dr. Nicole Farmer — The Mental Health Benefits of Cooking Apr 15, 2020

Show notes

Social distancing is the best way to curtail the spread of COVID-19, but if innumerable days of isolation start to feel like they're taking a toll on your mental welfare, there might be some solace waiting in the kitchen. According to mental health experts, cooking can reduce anxiety and alleviate mental distress. Dr. Nicole Farmer is a clinical researcher studying many facets of how diet affects human biology and behavior, including the effects of cooking interventions on mental well-being.

Dr. Farmer is a staff scientist at the NIH Clinical Center and a 2020 recipient of the William G. Coleman Jr. Minority Health and Health Disparities Research Innovation Award from the National Institute of Minority Health and Health Disparities (NIMHD).

Dr. Frank Lin — Radioactive Drugs for Rare Cancers Feb 24, 2020

Show notes

Radioactive drugs carry radioactive substances that can be engineered to specifically target and kill tumor cells inside the body. In 2018, the FDA approved a radioactive drug called Lutathera to treat tumors that affect the pancreas or gastrointestinal tract. Now, scientists at the NIH led by Dr. Frank Lin are testing whether Lutathera can also be effective against rare tumors of the adrenal glands. Dr. Lin is a clinician and researcher focused on bringing radioactive drugs — also known as radionuclides — from bench to bedside. His work could accelerate the development of new therapies for patients with rare cancers who have few or no other treatment options.

Frank Lin, M.D., is a Lasker Clinical Research Scholar in the Center for Cancer Research at the NIH's National Cancer Institute (NCI). Learn more about Dr. Lin and his research at https://irp.nih.gov/pi/frank-lin

Dr. Jerry Yakel — Acetylcholine Receptors and Neurological Disease Jan 27, 2020

Show notes

The neurons in our brains use both electrical and chemical signals to communicate. When those signals are not generated or interpreted correctly, serious problems can arise. Dr. Jerry Yakel is a neurobiologist studying acetylcholine receptors, which allow neurons to turn signals transmitted using the chemical acetylcholine into electrical messages. Because acetylcholine receptors are found on so many nerve cells, numerous neurological disorders can arise when they fail to work properly, including Alzheimer's, Parkinson's, and epilepsy. By studying these receptors, Dr. Yakel's team hopes to better understand how they contribute to disease, which could eventually lead to therapies for a variety of neurological conditions.

Jerry Yakel, Ph.D., is a Senior Investigator in the Ion Channel Physiology Group at the NIH's National Institute of Environmental Health Sciences (NIEHS). Learn more about Dr. Yakel and his research at https://irp.nih.gov/pi/jerrel-yakel
