Future Physician-Scientists Spent a Year in IRP Labs
Monday, September 21, 2020
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.
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.
Program Boosts Initiatives Supporting Researchers Across NIH
Tuesday, September 1, 2020
From Superbowl-winning football teams to comic book cohorts like The Avengers, combining the efforts of multiple talented individuals is a proven strategy for achieving remarkable results. It may come as no surprise, then, that the NIH’s Intramural Research Program (IRP) strongly encourages collaborations that breach the boundaries of its 24 Institutes and Centers. One example of these efforts is the Director’s Challenge Innovation Awards Program, which since 2009 has funded high-impact scientific projects that bring together researchers from across the IRP.
Study Also Reveals Immunotherapy’s Target on Cancer Cells
Tuesday, August 25, 2020
In the 1995 film The Usual Suspects, Kevin Spacey’s con man character famously remarks, “The greatest trick the Devil ever pulled was convincing the world he didn't exist.” The same could be said of cancer, which somehow persuades the body it is not a threat. Cutting-edge treatments called immunotherapies remove this façade and encourage the immune system to attack cancer cells. New IRP research in mice has demonstrated the promise of a new immunotherapy for treating ovarian cancer and identified a marker on cancer cells that could help clinicians identify patients who are most likely to benefit from the therapy.
IRP Leverages Supercomputing to Combat Coronavirus
Wednesday, August 19, 2020
Over the past six months, a tiny virus has completely upended life in the United States and many other countries. To combat this microscopic threat, some IRP researchers have turned to a tool the size of a small building.
Biowulf, the NIH’s supercomputer, is supporting more than a dozen different IRP research projects focused on the novel coronavirus. As the world’s most powerful supercomputer solely dedicated to biomedical research, Biowulf allows scientists to analyze data and run simulations at unprecedented speed. Two weeks ago, a blog post described how IRP investigators are using Biowulf to elucidate the structure of the novel coronavirus and simulate how potential therapeutics might interact with it. Picking up where that post left off, this blog will explore the application of Biowulf to important questions about the spread of COVID-19 and the way that its genes, along with our own, might influence its impact on the body.
Experimental Treatment Curbs Autoimmune Eye Disease in Mice
Tuesday, August 11, 2020
Our cells produce a wide range of chemicals necessary for good health, but when they cannot manufacture enough of these substances, scientists can use cells cultivated in their labs to pick up the slack. In a promising example of this approach, IRP scientists stimulated lab-grown immune cells to produce tiny bundles of an important anti-inflammatory molecule and used those packages to successfully treat a potentially blinding autoimmune disease in mice.
Biowulf Lends Massive Computing Power to NIH Research Efforts
Monday, August 3, 2020
Nations around the world are bringing every weapon in their arsenals to the fight against the COVID-19 pandemic: vaccines, new and existing therapeutics, personal protective equipment like face masks, and enough hand sanitizer to fill the Atlantic Ocean. The NIH community is contributing to this unprecedented effort with a tool that no other research institution can claim: Biowulf, the world’s most powerful supercomputer solely dedicated to biomedical research.
High-Tech Nicotine Delivery Technologies Raise Risk for Relapse
Tuesday, July 28, 2020
Scholars have long debated about the use of nuclear power, gene editing, and many other technologies that can have both positive and negative effects on society. Recently, researchers have been having similar discussions about the public health effects of electronic cigarettes. Adding to this debate, a new NIH study highlights a concerning drawback of e-cigarettes by showing they increase the risk that people who have successfully quit smoking will resume using tobacco products.
Mouse Study Illuminates Potential Mechanism Behind Mood and Anxiety Disorders
Tuesday, July 14, 2020
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.
IRP Research Examines Pandemic From All Angles
Tuesday, July 7, 2020
The sheer number of labs and wide variety of scientific perspectives in the IRP make it particularly well-suited to combating a disease like COVID-19, which is affecting patients’ health and the world around them in a huge number of ways. IRP researchers specializing in psychology, genetics, epidemiology, and many other disciplines are pursuing an array of strategies to learn more about the novel coronavirus.
