Tracking Sickle Cell Symptoms With Infrared Light

New IRP Study Supports Non-Invasive Way to Gauge Blood Vessel Health

Tuesday, January 7, 2025

Nobody likes being jabbed with a needle for blood tests, but for people with sickle cell disease, it’s a necessary and frequent annoyance to make sure their condition is under control. However, blood tests may become less needed in the future for those patients thanks to new IRP research that has identified ways to measure certain health metrics using non-invasive, light-based technologies.

A Weaker MRI Scanner Shows Its Strength

Less Powerful Magnetic Fields Improve Heart and Lung Imagery

Wednesday, November 8, 2023

On November 8, 1895, a physics professor in Bavaria was working in his darkened laboratory when he noticed glimmers of light breaking through a piece of heavy black paper and lighting up a screen behind it. As he placed thicker and heavier items between the source of light and the screen, the light remained. That was the day Wilhelm Röntgen accidentally discovered x-rays and changed medicine forever.

As we celebrate World Radiology Day on the 128th anniversary of that discovery, medical imaging now allows people to see inside the human body with a clarity Dr. Röntgen scarcely could have imagined. Magnetic resonance imaging (MRI), in particular, has seen huge advances due to the development of bigger and stronger magnets. In contrast to that trend, IRP Stadtman Investigator Adrienne Campbell-Washburn, Ph.D., has instead combined better software and hardware with a less powerful magnetic field to create a new type of ‘low-field’ MRI that is particularly useful for taking pictures of the heart and lungs and for guiding minimally invasive procedures.

Symposium Celebrates Award-Winning Female Scientists

Three Young Women Honored at Annual Event

Monday, May 8, 2023

Dr. Brittany Lord

There’s no doubt that science flourishes when it welcomes individuals with different backgrounds and perspectives. In pursuit of that goal, NIH has put considerable effort into closing the gender gap in the biomedical sciences, a field in which men significantly outnumber women, especially as the heads of labs and in leadership positions. Those efforts have so far yielded promising progress, with the proportion of women in IRP senior investigator positions increasing from 22 percent at the end of fiscal year 2016 to 27 percent at the end of fiscal year 2022. Over that same time period, women went from comprising 38 percent of IRP tenure-track investigators to 44 percent.

Part of what makes the IRP a welcoming place for female scientists is the NIH Women Scientists Advisors (WSA), a group of IRP scientists elected to represent the interests of women in the IRP. Once per year, the WSA selects a few female postdoctoral fellows or graduate students conducting research at NIH as WSA Scholars. At a symposium on April 13 honoring the achievements of this year’s Scholars, the awardees presented their efforts to learn more about a devastating childhood neurological condition, decrease health disparities in breast cancer, and use stem cells to investigate the roots of a nerve-destroying disorder. Read on to learn more about this year’s WSA Scholars and the important work they’re doing in their IRP labs.

IRP’s Bruce Tromberg Elected to National Academy of Medicine

Advances in Bioengineering Drive Life-Saving Medicine

Wednesday, January 18, 2023

Dr. Bruce Tromberg

“To discover new things, you need new ways to see them,” says Bruce J. Tromberg, Ph.D., Director of the National Institute of Biomedical Imaging and Bioengineering (NIBIB). That’s why he has spent the past 30 years of his career improving and inventing tools to help doctors and scientists conduct cutting-edge biomedical research and apply their findings to the task of saving lives. This past October, Dr. Tromberg was elected to the National Academy of Medicine (NAM) for his contributions to the fields of biophotonics and biomedical optics, as well as his leadership in the biomedical engineering and imaging community.

NIH History Shows Off Its Spooky Side

Museum Collection Contains Many Eye-Catching Objects and Photographs

Monday, October 31, 2022

Anyone who has engaged in a marathon of gruesome Halloween movies knows that the human body can be portrayed in ways that are frightening. Even in real life, the tools and techniques researchers use to understand disease may seem like something out of a work of fiction. In honor of Halloween this year, let’s sneak inside the archives of the Office of NIH History & Stetten Museum to see the spookiest nooks and crannies of our collection. Whatever you do, don’t turn out the lights!

Teaming Up to Tackle Engineering Challenges

Innovation Awards Accelerate Development of New Research Techniques

Monday, September 19, 2022

Scientists spend years, even decades, intensely studying a specific disease or biological system, an approach that yields unrivaled knowledge. However, many important scientific questions require a deep understanding of several subjects. As a result, the IRP has numerous programs dedicated to encouraging scientists with different areas of expertise to work together.

One such program is the NIH Director’s Challenge Innovation Awards, which funds innovative, high-impact projects that require the cooperation of researchers in more than one of NIH’s Institutes and Centers. This year, the program selected six promising proposals with one foot in the disciplines of biology and medicine and another in engineering or the physical sciences.
