Calming Kids’ Runaway Emotions

Brain Research Helps Understand and Treat Childhood Anxiety

Monday, May 19, 2025

It’s perfectly normal for young children to throw tantrums or be nervous on their first day of school, and for adolescents to be anxious about what their peers think of them. However, for some children and teens, negative emotions can escalate to unhealthy levels, resulting in significant distress and impairing their quality of life. 

IRP senior investigator Daniel Pine, M.D., is on a mission to understand how that happens and figure out ways to help those kids. In honor of Mental Health Month, we talked with Dr. Pine about how his research is revolutionizing the field of pediatric psychiatry and paving the way for new, non-pharmaceutical treatments.

A Summer of Science

Summer Poster Days Showcase IRP Summer Intern Research

Monday, August 19, 2024

IRP summer intern Thomas Savage

Every summer, NIH welcomes hundreds of enthusiastic young men and women to its campuses to work as summer interns, providing them with scientific training and mentorship from some of the world’s preeminent researchers. As always, the Summer Internship Program culminated this year with Summer Poster Days, held on August 1 and 2, a bustling event where summer interns showcase the results of their immersion into IRP research. Nearly 800 IRP summer interns participated in this year’s event, presenting research on cancer vaccines, new applications for virtual reality technology, experimental antifungal treatments, how the brain perceives pitch in sounds, and much more. Read on for a glimpse at some of this year’s summer interns and the work they braved a blazing Washington, D.C., summer to pursue.

Med Students Dip Their Toes Into IRP Research

Dozens of Doctors-To-Be Spent a Year Working in IRP Labs

Thursday, June 20, 2024

American medical and dental schools do an excellent job of producing caring and knowledgeable medical professionals, but they don’t always provide opportunities for their students to get a taste of life in the lab. For a few dozen of those students each year, NIH’s Medical Research Scholars Program (MRSP) fills in that gap, welcoming a cadre of future physicians to NIH for a year of research in IRP labs. 

Over the past year, 52 medical students have been getting their feet wet in biomedical research under the guidance of experienced IRP scientists. Whether investigating new ways to detect diabetes or trying to improve ADHD treatment, the 2023-2024 class of MRSP participants received a world-class crash course in how to make new discoveries that will improve patients’ lives. Read on to get your own crash course on some of the exciting research they have been conducting over the past year.

Picturing Stroke Recovery

IRP’s Larry Latour Peeks Into the Damaged Brain

Tuesday, May 28, 2024

x-ray view of the brain as a person experiences a stroke

The word ‘stroke,’ attributed to the idea of ‘a stroke of God’s hand,’ was first used in 1599 to describe the sudden seizure, paralysis, and brain damage that was previously called ‘apoplexy.’ It was a fitting analogy. Strokes, which affect nearly 800,000 Americans every year, hit suddenly and terrifyingly, with devastating consequences. Speed is critical to good treatment outcomes, but until recently very little could be done. 

May is Stroke Awareness Month, a time to draw attention to the risks and symptoms of stroke and the new treatments that are helping people recover with fewer lasting effects. We recently spoke with IRP senior scientist Lawrence L. Latour, Ph.D., an expert on brain imaging who leads the Acute Cerebrovascular Diagnostics Unit, a unique partnership between the NIH Intramural Research Program and two hospitals in the metro, D.C., area: Suburban Hospital and Medstar Washington Hospital Center. The collaboration, launched in 2000, aimed to incorporate magnetic resonance imaging (MRI) in examinations of patients experiencing symptoms of stroke. This allowed the clinicians to diagnose patients more easily and then, through imaging at later time points, look at how patients responded to their treatments in order to learn ways to improve therapy.

Hunger Hormone Feeds Alcohol Cravings

IRP Researchers Pursue New Approaches to Treating Alcohol Use Disorder

Wednesday, April 12, 2023

While most adults in the U.S. consume alcohol in moderation, for nearly 30 million of them, going even one day without alcohol feels nearly impossible. For these Americans, alcohol use disorder (AUD) is a serious condition that harms their health, relationships, and career. Unfortunately, only a small percentage of people with AUD receive treatment, and even then, for many patients, the chances of a relapse are high.

As the search for a reliable and effective treatment continues, IRP senior investigator Lorenzo Leggio, M.D., Ph.D., is exploring the biological processes that underlie alcohol cravings to unlock new approaches to therapy. April is Alcohol Awareness Month, so we took the opportunity to speak with him about recent discoveries made by his IRP team and its collaborators.

Examining the Roots of Opioid Use Disorder

IRP Researchers Are Peering Into the Brain to Learn Why Opioid Drugs Are So Hard to Quit

Monday, March 13, 2023

The ancient Egyptians, despite their significant anatomical knowledge, thought the heart was the seat of intelligence. Over the millennia, that view changed as philosophers and scientists alike came to appreciate the extraordinary role of the brain. It is partly thanks to them that we celebrate Brain Awareness Week every March. In honor of this observance, we took the opportunity to talk with IRP senior investigator Yihong Yang, Ph.D., and postdoctoral fellow Ida Fredriksson, Ph.D., Pharm.D., about their investigation into how cravings for opioids build during a period of prolonged abstinence, often leading to relapse.

Boosting Brain Activity to Suppress Snacking

Non-Invasive Stimulation Method May Improve Self-Regulation Around Food

Tuesday, November 22, 2022

Marketers make a living from the fact that merely seeing an advertisement for junk food can spur a sudden craving for potato chips or sugary cereal. Some people have an easier time than others resisting such urges, and over-consuming that sort of food can have problematic consequences for health. Findings from a recent IRP study suggest that stimulating a particular part of the brain might help people who struggle with obesity by enhancing their ability to control their desire to snack.

Neuroimaging Study Supports Two-Stage Theory of Recall

Results Suggest Dual Functions for Memory-Related Brain Area

Tuesday, August 16, 2022

Scientists studying memory have been closely scrutinizing a brain structure called the hippocampus ever since a man named Henry Molaison — better known as ‘patient H.M.’ — lost his ability to create new memories after surgeons removed that portion of his brain as a last-ditch treatment for his unrelenting epileptic seizures. For the most part, that research has treated the hippocampus as one homogenous structure. However, a recent IRP study lends support to the growing recognition that recall is a multi-stage process in which different parts of the hippocampus play different roles.

A One-Stop Shop for Pain Research

NIH Pain Research Center Shines Light on a Common and Complex Ailment

Monday, April 25, 2022

At one time or another, practically everyone has had a headache, stubbed their toe, or scorched their mouth on a hot slice of pizza, making pain one of the few experiences that essentially all people share. Despite its everyday nature, however, pain remains extremely mysterious. Even more enigmatic is chronic pain, which may not even stem from a clearly defined source yet affects more than a fifth of American adults.

Given the near-universality of pain and its huge social and economic burden, it’s no surprise that many researchers at NIH study it. Yet, prior to 2019, there was no central, shared entity in the NIH’s Intramural Research Program that united the many scientists performing this important work. That was the year NIH’s Pain Research Center was established, with the help of funding from the NIH Director’s Challenge Innovation Awards.

Three-Minute Talks Pit Researchers Against the Clock

IRP Scientists Keep it Short and Sweet in Competition’s Final Round

Wednesday, July 7, 2021

Science is so closely associated with long, jargon-laden lectures that scientists like Neil deGrasse Tyson and the IRP’s own Anthony Fauci have become celebrities for their ability to explain complex scientific concepts in a succinct and understandable way. On June 25, 17 postbacs, graduate students, and postdocs from across NIH showcased their own communication chops in the final round of the IRP’s annual Three-Minute Talks (TmT) competition.
