IRP Researchers Engage and Educate at Competition Finals

English is generally considered the ‘international language of science,’ since nearly all scientific papers are published in English. Yet, even to a native English speaker, scientists seem to be using another language entirely to talk about their research. Most Americans, after all, don’t know an ‘autophagosome’ from a ‘lysosome’ and would be hard-pressed to explain the difference between an ‘oocyst’ and a ’sporozoite.’
Fortunately, efforts like NIH’s annual Three-Minute Talks (TmT) competition are helping scientists learn how to communicate about their research in a manner that is much easier to understand. On June 30, after months spent whittling down dozens of competitors from across the IRP, 10 finalists raced against the clock to explain their work and its importance in a clear and compelling way.
Prediction Method Could Help Prevent Age-Related Physical Decline

Throughout human history, people have sought insight into their fates from self-proclaimed psychics and other dubious fortune tellers. Fortunately, scientists are increasingly developing more reliable, data-driven ways to predict the future. For instance, IRP researchers recently showed that an assessment of the cellular batteries that power our muscles can predict the deterioration of physical abilities in older adults.
Nursing Research Leader Sheds Light on How Neighborhoods Influence Health

When you think about public health, city planning might not be the first thing that comes to mind. Yet where we live — the quality of the buildings, the availability of places to walk and play safely, and the types of schools and stores in the neighborhood — can profoundly affect our health. This relationship has been emphasized by the COVID-19 pandemic, as close, stuffy living conditions, the need to take public transportation to essential jobs, and inequities in access to testing and vaccination sites all contributed to the larger reduction in life expectancy for Black and Latino Americans compared to Caucasians over the last two years.
Shannon N. Zenk, Ph.D., M.P.H., R.N., F.A.A.N., Director of the National Institute of Nursing Research (NINR), was elected to the National Academy of Medicine in 2021 for her research into how neighborhood characteristics affect the health of residents and contribute to the health disparities seen between communities with different racial and ethnic makeups and different levels of income.
IRP Research Challenges Long-Held Ideas About Muscle Structure

It’s not every day an accidental observation overturns 100 years of biological knowledge. But that’s what happened when IRP Stadtman Investigator Brian Glancy, Ph.D., noticed something funny while reviewing high-definition 3D videos of muscle cells.
“To be honest, you could almost call this study an accident,” he says.
Dr. Glancy, who leads the National Heart, Lung, and Blood Institute (NHLBI)’s Muscle Energetics Lab, often uses the high-powered microscopes available through the NHLBI Electron Microscopy Core to study how energy is distributed through skeletal muscle cells — the ones that control voluntary movement — when they expand and contract.
Although he was focused on examining the cells’ energy-producing mitochondria, he could also see the other structures inside them, including the long, tube-like structures called myofibrils that are involved in muscle contraction. As he advanced the video and traveled down the length of the muscle, it looked to him like the myofibrils were changing shape.
Research Suggests Sleep- and Activity-Based Approaches to Treatment

Mental Illness Awareness Week, observed this year from October 3 through 9, brings attention and support to the many patients and families who are coping with a variety of psychological conditions. Although an estimated 20 percent of U.S. adults and nearly 17 percent of youth have some type of mental health ailment, these conditions are still not well understood. However, research conducted at the National Institute of Mental Health (NIMH) is transforming our knowledge of one such mental health condition that affects more than two million Americans: bipolar disorder.
Scientists-in-Training Impress at Virtual Event

Despite the challenges of working during a global pandemic, IRP scientists continue to make groundbreaking discoveries and mentor the next generation of researchers. This includes the hundreds of recent college graduates conducting research in NIH labs through the Postbaccalaureate IRTA program. On April 28, 29, and 30, many of these budding scientists presented the fruits of their efforts at this year’s virtual Postbac Poster Day. Read on to learn about a small sampling of the scientific strides NIH’s postbacs are making.
IRP Research Overturns Common Concerns About ‘Weight Cycling’

With 2021 less than a month away, many of the more than 200 million Americans who are overweight or obese are beginning to consider making weight loss their New Year’s resolutions — perhaps not for the first time. While trying to lose weight only to ultimately regain it may be disappointing, a new IRP study suggests that repeated attempts at weight loss significantly reduce a person’s risk of dying.
Future Physician-Scientists Spent a Year in IRP Labs

Many doctors not only treat patients directly, but also make valuable contributions to research that will improve medical care in the future. Each one of these talented ‘physician-scientists’ began his or her research career under the guidance of a more senior scientist. At the NIH, the Medical Research Scholars Program (MRSP) provides just such an experience to promising young medical students from all across the United States.
Hundreds of Young Researchers Present Their Work Online

The COVID-19 pandemic has dramatically altered the way scientists are doing their work. Nevertheless, scientific research is a highly collaborative and interactive enterprise, so it remains essential for researchers to share and discuss their ideas and discoveries.
Every spring, the NIH’s Postbac Poster Day offers recent college graduates participating in the NIH’s Postbaccalaureate IRTA program the chance to show off the fruits of their labors and talk about their projects with both their fellow postbacs and the NIH’s many seasoned scientific veterans. Due to the need to maintain social distancing, the NIH's Office of Intramural Training and Education (OITE) went through considerable effort to move this year’s Postbac Poster Day to an online forum. The OITE staff's hard work paid off handsomely, with more than 870 postbacs presenting their research via WebEx on April 28, 29, and 30. Keep reading for a few examples of the fascinating scientific questions NIH’s latest crop of postbacs has been investigating.

Food companies have long marketed carbohydrate-rich drinks and energy bars to athletes with the message that the energy those snacks provide is key to lifting heavier and running farther. A new mouse study by IRP researchers, however, suggests that skipping a meal (or several) might be far more effective for increasing athletic prowess1.
Unlike modern Americans used to three square meals a day, our ancient ancestors couldn’t exactly throw a TV dinner in the microwave whenever they felt a bit peckish. As a result, they probably found themselves hunting wooly mammoths and fending off saber-toothed tigers on an empty stomach.
“From an evolutionary perspective, animals in the wild – particularly predators – need to be able to function at a high level when they’re in a food-deprived state,” says IRP Senior Investigator Mark P. Mattson, Ph.D., the study’s senior author. “Individuals who were able to perform at a high level in a fasted state had a survival advantage.”
