Millions of Americans suffered from depression and anxiety even before COVID-19 began upending their lives. To make matters worse, the stresses of living through a pandemic might not only worsen mental health but could also wreak havoc on the brain itself. New IRP research has found that psychological stress damages blood vessels in the brains of mice and dramatically alters the behavior of genes in certain blood vessel cells.

Whether from candy, soda, or fruit, sugar is the preferred source of sustenance for many people, and also for their brains. However, in patients with Alzheimer's disease, brain cells are less capable of turning sugar into energy. New IRP research provides evidence that this problem and the cognitive symptoms it causes could be partially solved by providing the brain with an alternative fuel.
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.
Event Spotlights Students Completing Their Ph.D. Research in IRP Labs

The NIH provides an extraordinarily rich environment for learning and honing the skills needed to pursue a scientific career. It’s no wonder, then, that Ph.D. students from institutions all across the United States and the rest of the world come here to conduct their dissertation research under the mentorship of the IRP’s many renowned investigators.
Nearly 150 of those students presented the fruits of their scientific work at the NIH’s 16th annual Graduate Student Research Symposium on Thursday, February 20. The insights they have produced on topics from cancer to autoimmune disease to environmental contaminants were supremely impressive and will likely contribute to important improvements in medical care in the future. For anyone who missed this exciting event, read on to learn about a few of the many research projects that were on display.
Decreased Energy Production Could Contribute to Cancer-Related Fatigue
By Brandon Levy

We all know the feeling of being wiped out after a hard workout or a grueling day at the office — you just want to flop down on the couch and not move, or even think. For many cancer patients, the treatment for their disease can trigger that sort of physical and mental exhaustion for weeks or months. New IRP research has found evidence linking this phenomenon, known as cancer-related fatigue, to a slow-down in cells’ energy-producing mitochondria.
Study Shows How Molecular Trespasser Gains Entry into Cells’ Energy Producers

As a fan of the long-running animated sitcom The Simpsons, I’ve witnessed the bumbling Homer Simpson cause several near-meltdowns at the nuclear power plant where he works. Serious problems can arise at such facilities when the wrong person gains access to them, and the same applies to the energy-producing mitochondria that power our cells. A new IRP study has revealed how a protein known to harm neurons gains entry into mitochondria in order to wreak cell-killing havoc.
Mouse Study Supports Potential Treatment Approach for Numerous Neurological Diseases

Winter is fast approaching, bringing with it both picturesque snow flurries and raging blizzards. It's a good reminder that something that is desirable in moderate amounts can be downright dangerous in large quantities, and the systems that keep our cells healthy are no different. IRP researchers recently found a novel way to tamp down a runaway cellular process that can kill neurons, findings that may one day lead to new treatments for several debilitating neurological conditions.
Five Questions with Dr. Catherine Bushnell

Yoga is all the rage these days, with millions of people taking part in the practice for relaxation, meditation, and increasing flexibility and muscle strength. However, the benefits of yoga go beyond what most might think. In fact, the mind-body practice of yoga could have a significant impact on the lives of those living with chronic pain, a condition that affects tens of millions of Americans.
In the past, doctors often prescribed opioids to treat chronic pain. However, research has shown that people with chronic pain have anatomical and neurochemical alterations in the brain that make them less responsive to opioids. In addition, both the medical and political systems are currently contending with a public health crisis stemming from the over-use of opioid pain medications. As a result, researchers have been working to identify ways to better manage chronic pain, particularly without the use of medication.
Annual Event Shares Research by IRP’s Summer Interns

NIH’s Natcher Conference Center was packed once again last Thursday for the annual Summer Poster Day. This year, more than 1,200 college and high school students spent their summer performing research in an IRP lab through the NIH’s Summer Internship Program.
I navigated through the more than 900 posters presented this year to get a taste of the impressive work done by these young men and women in less than three months. If they can make these kinds of discoveries in just one summer, imagine what they might one day accomplish as full-time scientists and clinicians!
Targeting Brain’s Stress Circuitry Curbs Rats’ Alcohol Consumption

For social drinkers, alcohol brings to mind barbecues and bar-hopping with friends, but for the roughly 16 million Americans with alcohol use disorder (AUD), drinking is a source of significant stress. Unfortunately, those negative emotions — particularly those experienced during withdrawal — drive people with AUD to drink even more. A recent IRP study points to a potential way to curb the desire to drink in people who abuse alcohol by altering the behavior of a brain structure that governs negative emotions.
