Nelson Mandela said, “Education is the most powerful weapon which you can use to change the world.” At NIH’s National Institute of General Medical Sciences (NIGMS), we believe that educating future and current scientists from diverse backgrounds benefits the entire biomedical research enterprise, changing the world through advances in disease diagnosis, treatment, and prevention.
As the summer winds down and students and educators embark on a new school year, I thought I’d highlight some of our educational resources that complement science, technology, engineering, and math (STEM) curricula. I’d also like to draw your attention to training programs designed to inspire and support research careers.
STEM Programs and Resources from NIH
The NIGMS Science Education Partnership Awards (SEPAs) are resources that provide opportunities for pre-K-12 students from underserved communities to access STEM educational resources. It lets them aspire to careers in health research.
The SEPA grants in almost every state support innovative, research-based, science education programs, furthering NIGMS’ mission to ensure a strong and diverse research ecosystem. Resources generated through SEPAs are free, mapped to state and national teaching standards for STEM, and rigorously evaluated for effectiveness. These resources include mobile laboratories, health exhibits in museums and science centers, educational resources for students, and professional development for teachers.
One SEPA program at Purdue University College of Veterinary Medicine, West Lafayette, IN, pairs veterinarians from their nationwide “superhero” League of VetaHumanz with local schools or community centers that support underserved students. These professional veterinarians, also from diverse backgrounds, strive to help young students from underrepresented groups envision future careers caring for animals.
Another SEPA program at Baylor University, Waco, TX, is increasing access to chemistry labs for high schoolers with blindness. It uses a robotic reactor with enhanced safety features to eliminate many dangers of synthetic organic chemistry. Students with blindness can control the robot to conduct experiments in a similar fashion to their sighted counterparts. The robot is housed within an airtight, blast-proof glove box, and it can perform common chemistry operations such as weighing and dispensing solid or liquid reagents; delivering solvents; combining reagents with the solvents; and stirring, heating, or cooling the reaction mixtures.
As noted in the 2021 report from the White House’s Office of Science and Technology Policy, “equity and inclusion are fundamental prerequisites for making high-quality STEM education accessible to all Americans and will maximize the creative capacity of tomorrow’s workforce.” I believe this statement falls right in line with the spirit of SEPAs.
New NIH-Wide STEM Teaching Resources Website
To help educators find free science education content, we recently launched a STEM teaching resources website. It includes NIH-wide teaching materials as well as those from SEPA programs for grades K-12, categorized by different health and research topic areas.
The NIGMS free educational resource Pathways, designed for educators and aspiring scientists in grades 6-12, is one of many resources available through the STEM website. Each issue of Pathways provides information about basic biomedical science and research careers and includes a student magazine, teacher lesson plans, and interactives such as Kahoot! classroom quizzes. Our most recent vaccine science issue teaches students how COVID-19 vaccines work in the body and introduces them to scientists dedicated to vaccine research.
Programs for Early Career Scientists
While SEPA grants focus on future scientists (and their educators) in grades pre-K-12, NIGMS also has a robust research training portfolio for those at the undergraduate through postdoctoral and professional levels. These programs aim to enhance diversity by engaging and training scientists from diverse backgrounds early in their careers.
At the undergraduate level, programs like Maximizing Access to Research Careers (MARC) provide students from diverse backgrounds with mentorship and career development. We recently highlighted the MARC program at Vanderbilt University, Nashville, TN, on our Biomedical Beat blog showing the program’s impact on students.
At the other end of the spectrum, our Maximizing Opportunities for Scientific and Academic Independent Careers (MOSAIC) program helps promising postdoctoral researchers from diverse backgrounds transition into independent faculty careers. The MOSAIC scholars become part of a career development program to expand their professional networks and gain additional skills and mentoring through scientific societies. You can learn more about each of these impressive early career scientists on our MOSAIC Scholars webpages.
At NIGMS, we’re dedicated to increasing the diversity of the biomedical research workforce. Through STEM content and outreach, as well as scientist training resources, we focus on emphasizing diversity, equity, inclusion, and accessibility. This holds true with funding and programming for current scientists, and in the inspiration and training of future scientists.

Note: Dr. Lawrence Tabak, who performs the duties of the NIH Director, has asked the heads of NIH’s Institutes and Centers (ICs) to contribute occasional guest posts to the blog to highlight some of the interesting science that they support and conduct. This is the 15th in the series of NIH IC guest posts that will run until a new permanent NIH director is in place.

It usually takes more than a decade to develop a safe, effective anti-viral therapy. But, when it comes to coronavirus disease 2019 (COVID-19), we don’t have that kind of time. One way to speed the process may be to put some old drugs to work against this new disease threat. This is generally referred to as “drug repurposing.”
NIH has been doing everything possible to encourage screens of existing drugs that have been shown safe for human use. In a recent NIH-funded study in the journal Nature, researchers screened a chemical “library” that contained nearly 12,000 existing drug compounds for their potential activity against SARS-CoV-2, the novel coronavirus that causes COVID-19 . The results? In tests in both non-human primate and human cell lines grown in laboratory conditions, 21 of these existing drugs showed potential for repurposing to thwart the novel coronavirus—13 of them at doses that likely could be safely given to people. The majority of these drugs have been tested in clinical trials for use in HIV, autoimmune diseases, osteoporosis, and other conditions.
These latest findings come from an international team led by Sumit Chanda, Sanford Burnham Prebys Medical Discovery Institute, La Jolla, CA. The researchers took advantage of a small-molecule drug library called ReFRAME , which was created in 2018 by Calibr, a non-profit drug discovery division of Scripps Research, La Jolla, CA.
In collaboration with Yuen Kwok-Yung’s team at the University of Hong Kong, the researchers first developed a high-throughput method that enabled them to screen rapidly each of the 11,987 drug compounds in the ReFRAME library for their potential to block SARS-CoV-2 in cells grown in the lab. The first round of testing narrowed the list of possible COVID-19 drugs to about 300. Next, using lower concentrations of the drugs in cells exposed to a second strain of SARS-CoV-2, they further narrowed the list to 100 compounds that could reliably limit growth of the coronavirus by at least 40 percent.
Generally speaking, an effective anti-viral drug is expected to show greater activity as its concentration is increased. So, Chanda’s team then tested those 100 drugs for evidence of such a dose-response relationship. Twenty-one of them passed this test. This group included remdesivir, a drug originally developed for Ebola virus disease and recently authorized by the U.S. Food and Drug Administration (FDA) for emergency use in the treatment of COVID-19. Remdesivir could now be considered a positive control.
These findings raised another intriguing question: Could any of the other drugs with a dose-response relationship work well in combination with remdesivir to block SARS-CoV-2 infection? Indeed, the researchers found that four of them could.
Further study showed that some of the most promising drugs on the list reduced the number of SARS-CoV-2 infected cells by 65 to 85 percent. The most potent of these was apilimod, a drug that has been evaluated in clinical trials for treating Crohn’s disease, rheumatoid arthritis, and other autoimmune conditions. Apilimod is now being evaluated in the clinic for its ability to prevent the progression of COVID-19. Another potential antiviral to emerge from the study is clofazimine, a 70-year old FDA-approved drug that is on the World Health Organization’s list of essential medicines for the treatment of leprosy.
Overall, the findings suggest that there may be quite a few existing drugs and/or experimental drugs fairly far along in the development pipeline that have potential to be repurposed for treating COVID-19. What’s more, some of them might also work well in combination with remdesivir, or perhaps other drugs, as treatment “cocktails,” such as those used to successfully treat HIV and hepatitis C.
This is just one of a wide variety of drug screening efforts that are underway, using different libraries and different assays to detect activity against SARS-CoV-2. The NIH’s National Center for Advancing Translational Sciences has established an open data portal to collect all of these data as quickly and openly as possible. As NIH continues its efforts to use the power of science to end the COVID-19 pandemic, it is critically important that we explore as many avenues as possible for developing diagnostics, treatments, and vaccines.

For any aspiring juggler, the path to greatness requires mastering the dreaded “five-club backcross.” It’s a move that begins by juggling five clubs in front of your body and transitions to doing the same thing behind your back! Dr. Noah Cowan has nailed it once, and vows to do it again one day.
But this NIH-funded neuroscientist and bioengineer, who directs the Locomotion in Mechanical and Biological Systems (LIMBS) Laboratory at Johns Hopkins University’s Whiting School of Engineering in Baltimore, doesn’t have much time to practice his juggling these days. Instead, he is focusing on ways to use virtual juggling, such as the ball-and-paddle system shown in the video above, to explore the biomechanics of motion. His ultimate goal? To apply what he’s learned to advance the fields of robotics, prosthetics development, and physical therapy.
