Epidemiologists are the watchful guardians of public health. They collect and analyze data to track the status quo. When there are deviations, they crunch the numbers to understand who is getting sick, where, how, and why. Dr. Meredith Shiels is an epidemiologist and senior investigator at the National Cancer Institute (NCI) studying cancer mortality rates to discern what populations might be at higher risk, figure out ways to mitigate those risks, and evaluate whether those measures are working.

Finding treatments for mental health conditions doesn't just deal with people who live with them. Healthy volunteers play a critical part in the science of understanding our brains and behavior. But what qualifies as "healthy" can vary across labs and skew how scientists interpret study results. Dr. Joyce Chung, the Deputy Clinical Director at the National Institute of Mental Health (NIMH), is changing that. She is creating a pool of vetted volunteers to bolster the integrity, efficiency, and safety of mental health research.

Science is receptive to new information that can refine the theories we use to make sense of the world. Such is the case with Dr. Lauren Porter, a Stadtman investigator at the National Library of Medicine who is helping redefine the way we understand how proteins behave. She is looking at a new class of proteins that can change their structure and function much like the famous Transformer robots that morph into different machines. Understanding how these proteins switch their shape could help scientists understand the molecular basis of certain diseases like cancer and Alzheimer’s.

Centuries of selective breeding have given rise to a staggering variety of dog breeds, each with its own traits and behaviors. But shallow gene pools have also put some breeds at higher risk for disease. Dr. Elaine Ostrander runs the Dog Genome Project at the National Human Genome Research Institute. Her team includes Dr. Heidi Parker. Together, they are digging for clues to understand how genes code for dogs' diversity and disease. Clues that might also inform the health of their two-legged caregivers.

The annual flu vaccine is the best way to prevent yourself and others from getting sick. But sometimes the antigens the vaccine trains your body to fight are not similar enough to the strains of influenza circulating that year. This mismatch allows viruses to fly under the radar and spread undetected. It's a problem scientists hope to solve with a universal flu vaccine. Dr. Matthew Memoli is an influenza expert at the National Institute of Allergy and Infectious Diseases (NIAID). He is preparing to test a new vaccine candidate that could offer protection from more flu strains and for more people.

There is more to color than meets the eye. According to Dr. Bevil Conway, how we perceive color can inform how our brains receive, interpret, and generate knowledge about the world. Dr. Conway is a visual artist and a neuroscientist at the National Eye Institute. He is working to decode the neural basis of color. In a recent study, his lab mapped how different colors can stimulate different patterns of brain activity.

The success of mRNA vaccines against the coronavirus that causes COVID-19, has brought RNA biology into the limelight. Now, with the world's attention, what's next for this biomedical rising star? NIH scientists, Dr. Richard Maraia and Dr. Natasha Caplen, have long recognized the potential of RNA in improving human health. In this episode, they discuss the prospects of RNA biology and how their work could inform the future of RNA as an innovative class of medicine.

When the COVID-19 pandemic struck, racial and ethnic minority groups were disproportionately hit. The health inequities pulled at the seams of a system that was already frayed. Dr. Anna Nápoles works to close gaps in healthcare as the first Latina scientific director of the National Institute on Minority Health and Health Disparities (NIMHD). She is reducing the types of hurdles that once hindered her parents so that all populations can live long, healthy, and productive lives.

Pregnancy is by no means necessary for motherhood, but it is necessary for life. And it's no picnic. A pregnant person can experience complications like anemia, UTIs, hypertension, diabetes, and exhaustion. Maintaining maternal health during pregnancy can be challenging, but it is integral for the health of the fetus. Dr. Diana Bianchi is a physician-scientist and the director of the National Institute of Child Health and Human Development (NICHD), where she works to improve care for the mommy-baby unit.

Small errors can quickly escalate to have large repercussions. When it comes to cancer, molecular changes to DNA can trigger chain reactions that cause cells to go awry and spread uncontrollably. Dr. Louis Staudt works to identify such changes, known as genetic mutations, and find ways to stop them from snowballing into a deadly disease. In this episode, Dr. Staudt recounts the story of how he differentiated subtypes of lymphomas to develop a treatment for patients as an early success of precision medicine.
Dr. Staudt is a principle investigator and the director of the Center for Cancer Genomics at the National Cancer Institute. He was recently elected into the National Academy of Medicine. Learn more about his research at https://irp.nih.gov/pi/louis-staudt.

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.

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.

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 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
