NIGMS and Scholastic bring you Pathways: The Anesthesia Issue, which explores pain and the science behind anesthesia—the medical treatment that prevents patients from feeling pain during surgery and other procedures. Without anesthesia, many life-saving medical procedures would be impossible.
Pathways, designed for students in grades 6 through 12, aims to build awareness of basic biomedical science and its importance to health, while inspiring careers in research. All materials in the collection are available online and are free for parents, educators, and students nationwide.
“If I was going to do science, I wanted it to help people,” says Julia Bohannon, Ph.D., an assistant professor of anesthesiology at Vanderbilt University Medical Center in Nashville, Tennessee.
Dr. Bohannon researches therapies that could help prevent infections in patients with severe burn injuries. Infections are common in these patients because burn injuries typically suppress the immune system. Dr. Bohannon originally planned to become a burn surgeon, inspired by the doctor who treated her after she was severely burned as a child. But during her junior year of college at Eastern Kentucky University in Richmond, she started working in a genetics lab and enjoyed it so much that she began considering a research career.
Choosing a Path Forward
After graduating with her bachelor’s degree, Dr. Bohannon worked for 2 gap years in a translational research lab at the University of Kentucky to decide between pursuing an M.D. or a Ph.D. She ultimately entered a Ph.D. program at the University of Texas Medical Branch in Galveston and conducted research in the lab of Tracy Toliver-Kinsky, Ph.D., at the Shriners Children’s burn center. Upon earning her Ph.D., Dr. Bohannon took a postdoctoral position with Edward Sherwood, Ph.D., at the University of Texas Medical Branch, where she studied potential treatments to improve immune cell function after burns. To continue her work, she followed Dr. Sherwood a year later when he moved to Vanderbilt University Medical Center.
Formation of a biofilm often involves a process called quorum sensing. In this process, microbes detect when they reach a certain population density and change their behavior in ways that help them function as a community.
Your immune system is on patrol every day. It protects your body from bacteria, viruses, and other germs. But if something goes wrong, it can also cause big problems.
Sepsis happens when your body’s response to an infection spirals out of control. Your body releases molecules into the blood called cytokines to fight the infection. But those molecules then trigger a chain reaction.
“Sepsis is basically a life-threatening infection that leads to organ dysfunction,” says Richard Hotchkiss, M.D., who studies sepsis at Washington University in St. Louis, Missouri. The most dangerous stage of sepsis is called septic shock. It can cause multiple organs to fail, including the liver, lungs, and kidneys.
Septic shock begins when the body’s response to an infection damages blood vessels. When blood vessels are damaged, your blood pressure can drop very low. Without normal blood flow, your body can’t get enough oxygen.
“If you bring a public health program to people where they live, you can get amazing results,” says Peter Katzmarzyk, Ph.D., a professor of pediatric obesity and diabetes at Pennington Biomedical Research Center, Louisiana State University. Specifically, bringing health programs into underserved communities can lead to strong engagement and positive changes in people’s health. Dr. Katzmarzyk is part of the NIGMS-funded Louisiana Clinical & Translational Science Center (LA CaTS), a collaboration between 10 academic, research, and health care delivery institutions that focuses on reducing health disparities in Louisiana.
NIGMS’ Small Business Technology Transfer (STTR) program works toward more effective methods for patient screening, diagnosis, and treatment.
Translating lab discoveries into health care products requires large investments of time and resources. Through the STTR Regional Technology Transfer Accelerator Hubs for IDeA States program, NIGMS helps researchers interested in transitioning their discoveries and/or inventions into products. Here are the stories of three researchers working with the XLerator Hub, which funds projects in the southeastern United States and Puerto Rico.
Ending Diagnostic Delays for Endometriosis

Idhaliz Flores-Caldera, Ph.D., a professor of basic sciences and OB-GYN at Ponce Health Sciences University in Puerto Rico, has studied endometriosis for nearly 20 years. Endometriosis occurs when endometrial tissue, which typically lines the uterus, grows elsewhere in the body. Dr. Flores-Caldera first had the idea for a noninvasive diagnostic test for the disorder about 10 years ago. But it was only when she learned about funding opportunities from the XLerator Hub that she saw a path to validating her preliminary research findings and eventually commercializing her test.
Dr. Flores-Caldera applied for and was accepted into the hub’s proof-of-concept program, Ideas to Products, which funds researchers to flesh out ideas they want to commercialize. “I am very appreciative of how the program has provided me with tools and knowledge about commercializing a product and the process of patenting a product,” she says. “In general, scientists aren’t educated on this important topic.”
NIGMS, in collaboration with Scholastic, has developed a collection of free biology and health activities on the educational app Kahoot! You can play them alone, with friends, or with a class of students. Four Kahoots! are currently available:

Since the virus that causes COVID-19, known as SARS-CoV-2, was first reported in late 2019, scientists have launched hundreds of studies on strategies for diagnosis, prevention, and treatment. To prioritize the most promising vaccine and therapeutics candidates, streamline clinical trials, and coordinate regulatory processes, the National Institutes of Health (NIH) and the Foundation for the NIH have established the Accelerating COVID-19 Therapeutic Interventions and Vaccines (ACTIV) partnership. ACTIV brings together eight government entities, 20 biopharmaceutical companies, and four nonprofit organizations.

Since the start of the COVID-19 pandemic, researchers from many areas of biomedical science have worked together to learn how this new disease affects the human body, how to prevent its spread, and how to treat it. Severe cases of COVID-19 and cases of sepsis share many symptoms. Sepsis is the body’s overactive and extreme response to an infection. It’s unpredictable and can progress rapidly. Without prompt treatment, it can lead to tissue damage, organ failure, and death.
Sepsis has similarities with some cases of COVID-19, most likely because the two conditions trigger the same reactions at the cellular level. Researchers have studied these reactions in sepsis for many years.
“When we look back on 2020 and the speed with which progress was made against COVID-19, two features will stand out,” says John Younger, M.D., a member of the NIGMS Advisory Council who recently co-chaired a working group on advancing sepsis research. “The first is how quickly the biotechnology community came together to develop vaccine candidates. The second, and arguably the most immediately impactful, is how caregivers and clinical researchers were able to rapidly refine the care of COVID-19 patients based on decades of experience with sepsis.”
This post highlights a few of the many sepsis researchers supported by NIGMS who are applying their expertise to COVID-19.
When someone mentions aging, you may think of visible changes, like graying hair. Scientists can see signs of aging in cells, too. Understanding how basic cell processes are involved in aging is a first step to help people lead longer, healthier lives. NIGMS-funded researchers are discovering how aging cells change and applying this knowledge to health care.
Discovering the Wisdom of Worms

Aric Rogers, Ph.D., and Jarod Rollins, Ph.D., assistant professors of regenerative biology and medicine at Mount Desert Island (MDI) Biological Laboratory in Bar Harbor, Maine, are investigating aging by studying a tiny roundworm, Caenorhabditis elegans. Researchers often study C. elegans because, though it may seem drastically different from humans, it shares many genes and molecular pathways with us. Plus, its 2- to 3-week lifespan enables researchers to quickly see the effects of genetic or environmental factors on aging.
Drs. Rogers and Rollins investigate how C. elegans expresses genes differently under dietary restriction, enabling it to live longer. Understanding how genes are expressed when organisms live an extended life sheds light on the genetics underlying aging. This information could help researchers develop drugs or behavior modification programs that prolong life and delay the onset of age-related diseases such as heart disease, diabetes, cancer, and dementia.
