IRP Scientists Sound Off in Three-Minute Talks

Annual Competition Tests Researchers’ Communication Skills

Tuesday, July 16, 2024

three hourglasses

Many scientists say that English is the international language of science, but if it is, it’s a form of English that many fluent English speakers might have trouble understanding. From ‘allosteric modulator’ to ‘zinc finger nuclease,’ the words that scientists use to talk about what they do can sound like a foreign language.

Fortunately, many current and upcoming scientists are making it a priority to learn how to communicate with people who don’t share their deep knowledge. As part of this effort, NIH’s annual Three-Minute Talks (TmT) competition brings forth dozens of IRP postbacs, graduate students, and postdocs to talk about their research to an audience of peers outside their own labs. On June 27, this year’s 11 finalists delivered clear, engaging, and — most importantly — short talks on topics ranging from skin bacteria to saliva.

Metabolic Inflexibility Drives Increased Appetite

IRP Research Could Aid Personalized Weight Loss Recommendations

Tuesday, July 9, 2024

We all know the stereotype of the picky child who shuns vegetables unless they’re smothered in ranch dressing or cheese. Surprisingly, the human body can also be similarly choosy about how it fuels itself. New IRP research shows that people whose bodies prefer to raid their sugar depots rather than use stored fat during a period without food consume more calories after their fast, suggesting a possible explanation for why some people are more prone to gaining weight over time or have less success with certain weight loss interventions.

IRP Graduate Students Show Off Their Work at Annual Symposium

Event Highlights Efforts of Early-Career Researchers

Monday, March 4, 2024

IRP graduate student Kenya Debarros poses with her scientific poster

The IRP’s reputation as a leader in biomedical research attracts scientists in all stages of their careers and from all corners of the U.S. and the world. Once a year, the motley collection of graduate students who are completing their Ph.D. research in NIH labs gets to tout its scientific accomplishments at NIH’s Graduate Student Research Symposium, which took place this year on February 15.

During the event’s two poster sessions, more than 120 IRP graduate students presented the results of their research so far, from the development of better ways to grow retina-like collections of cells in the lab to insights into how the brain regulates feelings of hunger. Read on for a brief look at a few of the IRP’s brilliant budding scientists and the discoveries they showed off at the event.

High-Fat Diet Alters Brain’s Response to Food

Mouse Study Identifies Neurological Obstacle to Dietary Improvements

Tuesday, September 15, 2020

Every morning, thousands of Americans wake up intending to eat more healthfully, only to find themselves chowing down on a greasy burger at dinnertime. In addition to the many biological and socioeconomic obstacles to healthy eating, a salad can just plain seem unappealing compared to a plate of crispy fries. According to new IRP research, a high-fat diet can dramatically alter how the brain responds to food in ways that make a more wholesome meal less enticing and satisfying.

IRP Interns Shine at Summer Poster Day

NIH summer intern Ishu Sivakumar at Summer Poster Day

Upon entering the sunny foyer of the NIH’s Natcher Conference Center last Thursday, I was immediately struck by a burst of loud, excited chatter. As it always is on NIH’s annual Summer Poster Day, the building was filled with hundreds of high school and college students and the scientists, families, and friends who had turned out to see what these young men and women had spent the summer doing.

Tracing the Neural Circuitry of Appetite

Wednesday, May 20, 2015

Reblogged from the NIH Director's Blog. Originally posted by Dr. Francis Collins, NIH Director, on May 5, 2015.

If you’ve ever skipped meals for a whole day or gone on a strict, low-calorie diet, you know just how powerful the feeling of hunger can be. Your stomach may growl and rumble, but, ultimately, it’s your brain that signals when to start eating—and when to stop. So, learning more about the brain’s complex role in controlling appetite is crucial to efforts to develop better ways of helping the millions of Americans afflicted with obesity.
