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.

The most important step to solving any problem is to choose the right tool for the job. Just like a heavy fur coat will keep you comfortable in the Arctic but slowly roast you in the Sahara, your immune system’s response can be helpful or harmful depending on the specific invader it’s fighting off. A new IRP study has identified a molecular “switch” that shifts an important type of immune cell between two different approaches to protecting the body.

Barbra Streisand knows how to command an audience, whether she’s behind a microphone, a camera, or a podium. After a storied career beguiling theater-goers, Streisand’s new goal is not just to warm hearts but to save them from disease as well.

It might seem easy to blame your parents for the way you turned out; after all, they raised you and gave you all of your DNA. But, before throwing blame around, consider saving some for the place where you grew up. According to new IRP research, being raised in an urban environment can dramatically alter how your genes influence your brain.1

Most people experience anxiety at some point in their lives, whether it’s pre-speech jitters or sweaty palms when their plane takes off. While mild feelings of nervousness are completely normal and can even be beneficial, anxiety can also have negative repercussions if it causes somebody to completely avoid situations like social encounters or taking a flight to visit distant family.

On Wednesday, May 2, hundreds of researchers gathered at NIH’s Natcher Conference Center to show off their recent discoveries. But unlike a typical scientific conference, the letters “M.D.” and “Ph.D.” were noticeably absent from these scientists’ credentials. Instead, the event — NIH’s annual Postbac Poster Day — celebrated the accomplishments of individuals participating in the NIH Postbaccalaureate Intramural Research Training Award (IRTA) Program.

Ever since the Human Genome Project (HGP) launched in 1990, patients and members of the public have been inundated with predictions about how unraveling the mysteries of genetics will revolutionize healthcare. Today, many of these promises remain unrealized, prompting some to become skeptical of the true utility of this research for improving human health. But, while more work is needed to fully realize the potential of genome-focused medicine, it remains true that patients are benefiting from our knowledge of the human genome in numerous, sometimes under-appreciated ways.

In the midst of the 1957 Asian flu pandemic, doctors and researchers were understandably focused on treating patients and developing ways to contain the outbreak. It wasn’t until 30 years later that scientists began reporting that women who were pregnant when they caught the virus were more likely to have children who would later be diagnosed with schizophrenia.1 While that relationship remains controversial,2 numerous studies have since linked activation of a pregnant woman’s immune system with an increased risk that her child will develop certain psychiatric disorders, including not just schizophrenia but also autism spectrum disorder and major depressive disorder.3 A new IRP study has now expanded on this work by showing that exposure to higher levels of two immune system molecules in utero can noticeably alter the neurological and cognitive development of young children.4
