For most of their history, computers have been limited to mindlessly executing the instructions their programmers give them. However, recent advances have given rise to the intertwined fields of artificial intelligence (AI) and machine learning, which focus on the creation of computer programs that can operate independently and even teach themselves to perform specific, specialized tasks. In 2013, the online PubMed database listed only 200 research publications related to ‘deep learning,’ a new type of machine learning that has shown success for particularly difficult tasks like object and speech recognition. Just four years later, in 2017, that number exceeded 1,100.

While many people can easily stop after a beer or two, for others one drink begets many more, ultimately leading to an addiction that drives continuously increasing alcohol consumption over time. New IRP research has identified a specific type of neuronal receptor involved in the development of alcohol dependence in mice, suggesting a possible approach to curbing problematic drinking behaviors in humans addicted to alcohol.

I knew very little about neuroscience before beginning my graduate studies, but the topic of neurodegeneration looked very interesting. Having applied to several labs, I landed a Ph.D. student position in a neuroscience lab at the Saha Institute of Nuclear Physics, a government research institute in India, that would propel me on my way to the NIH IRP. In the first year of my Ph.D. program, I learned several things about the central nervous system (CNS), but what intrigued me the most was its lack of ability to regenerate after injury.

The constant combat between cancer and the body’s defenses can wear a tumor out. Unfortunately, cancer cells can pause their life cycle to repair themselves before re-entering the fray with renewed vigor. According to new IRP research, preventing cancer from taking a time-out can make it more susceptible to attack by the immune system.

The NIH community and cancer scientists around the world were saddened to learn that Alan Rabson, M.D., a prominent former IRP researcher and Deputy Director of the NIH’s National Cancer Institute (NCI), passed away on July 4 at the age of 92.
Dr. Rabson first joined the NIH in 1955 as a pathologic anatomy resident in the NIH Clinical Center, which had opened just two years before, and he began studying cancer-causing viruses in an NCI intramural laboratory a year later. Over the course of his ensuing six decades with NIH, Dr. Rabson accumulated a great many stories, a few of which we have shared in his own words, pulled from a 1997 “NCI Oral History Project” interview.

Everyone has a different pain threshold; a plate that’s too hot for one person to touch might be easily handled by someone else, for example. Now, IRP researchers have found the first evidence that a person’s sensation of a painful temperature more strongly influences the body’s automatic response to it than does the actual temperature.

Hundreds of scientific studies have established that obesity often leads to severe health problems and cuts short many lives. Nevertheless, a significant number of obese people remain healthy despite their excess weight. A new IRP study has now identified a possible molecular marker that distinguishes obese but healthy individuals from those whose weight has negatively affected their health.

Research into the collection of microorganisms that live in and on our bodies — known as the microbiome — has dramatically expanded in recent years. In fact, the field is one of 12 domains designated as top long-term IRP research priorities. Since the establishment of the NIH’s Human Microbiome Project in 2007, investment in microbiome research across the IRP has increased over forty-fold and now occurs in dozens of labs across more than 20 institutes and centers.

Access to robust computing resources provides a critical foundation for advancing the wide variety of biomedical research taking place within the NIH’s Intramural Research Program (IRP). Whether performing molecular modeling simulations, generating whole-genome sequencing data, deducing the structures of biomolecules, or advancing drug discovery efforts, our ability to analyze large-scale biological and biomedical data strongly depends on our ability to employ computationally intensive approaches that produce interpretable results and advance translational efforts aimed at improving human health.

Like many research institutions across the nation, the NIH has faced difficulties with establishing a strong and lasting community of diverse investigators. We have made remarkable gains in recent years, however, in attracting and retaining a diverse workforce that's more reflective of the U.S. population.
One of many movers and shakers in this realm is Hannah Valantine, a cardiologist recruited from Stanford University who, in addition to maintaining a lab in NHLBI, is the NIH's first Chief Officer for Scientific Workforce Diversity. And one of her many ideas that the NIH Scientific Directors hope to adopt is the creation of a cohort program with both mentors and mentees committed to issues of scientific diversity and inclusion. Our goal is to guide this cohort of tenure-track investigators through the tenure process to be sure they have access to the mentoring, professional development, and networking opportunities to establish their careers, strengthen their science, and, in turn, recruit and mentor future generations of scientists.
