Many of us learned in English class that an antagonist is a person or thing that a hero fights. But in biomedical science, an antagonist is a molecule that binds to a cellular receptor to prevent a response, such as a muscle contraction or hormone release. Antagonists can be important medical treatments, like the antagonist naloxone—also known as Narcan —that can reverse an opioid overdose.

Pathways: The Vaccine Science Issue
NIGMS is pleased to bring you Pathways: The Vaccine Science Issue [PDF], which explains how the messenger RNA (mRNA) vaccines for COVID-19 work and how they were developed. Building on years of research, scientists were able to create these vaccines, thoroughly test them, and get them to the public as quickly as possible—while still making sure they were safe and effective.
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 for free.

“I love the mystery of chemistry. It explores the great unknown of the universe,” says Phil Baran, Ph.D., a professor of chemistry at Scripps Research, La Jolla, California. His passion for the subject catalyzed a successful career in organic synthesis—building molecules that are the foundation of living things and can be developed as medicines.
Setting His Sights on Science
School didn’t interest Dr. Baran until he found chemistry in 10th grade. “From there, the mission was clear: do whatever was required to do chemistry for the rest of my life,” he says. At the time, that meant achieving certain grades, so he focused on improving his academic performance. He also took courses at a community college and graduated with his high school diploma and associate degree simultaneously.

“Patients at urban and inner-city hospitals are in dire need of high-quality care and frequently don’t have access to clinician-scientists doing cutting-edge research. That’s part of what has made me committed to performing research in these settings,” says Faheem Guirgis, M.D., an associate professor of emergency medicine at the University of Florida College of Medicine, Jacksonville. Check out the highlights of our interview with Dr. Guirgis below to learn how he became a doctor and what inspired him to conduct research on sepsis.
Q: How did you become interested in science and medicine?
A: After the phase of wanting to be a firefighter or police officer, the next thing I remember wanting to be was a doctor. My father was and is my ultimate inspiration for pursuing a career in medicine. He was a family-practice physician committed to providing the best care possible for his patients before retiring recently, and they loved him.

The intricate process of mitosis—a cell splitting into two identical daughter cells—plays a pivotal role in sustaining life. Many scientists study this process to understand what’s needed for it to progress normally and why it sometimes goes awry, such as in cancer. During their research, the scientists often create eye-catching images and videos, and we showcase some of those visuals here.

“One thing that we try to develop in students is a sense of belonging and scientific identity,” says Edwin Barea-Rodriguez, Ph.D., the director of the Research Training Initiative for Student Enhancement (RISE) program at the University of Texas, San Antonio (UTSA). The program provides undergraduate and graduate students from underrepresented backgrounds with research experiences, professional development opportunities, and faculty mentorships. The UTSA RISE program has helped hundreds of students build strong foundations for scientific careers over its more than 20-year history. Here, we share the stories of three students who have benefited from RISE.
Support Beyond the Lab
After earning her bachelor’s degree in biochemistry, Kaira Church knew she loved research but wasn’t sure if graduate school was right for her. She took a job as a lab technician in the research group of Astrid Cardona, Ph.D., a professor of molecular microbiology and immunology at UTSA, where she learned firsthand what being a graduate student entailed. She was also introduced to RISE and was impressed by the variety of opportunities it offered. She decided to pursue a Ph.D. and applied to the program.
Kaira is now in her fourth year as a RISE trainee. “I really like the professional development and the networking that RISE offers,” she says. “A lot of science majors are stuck in the lab all the time. RISE ensures that we’re meeting people in our field so we have plenty of job opportunities when we graduate.”

Jenny Durrin says she would never have become the director of the Seed Potato Germplasm Program at the University of Idaho, Moscow, without the experience she gained through the Idaho IDeA Networks of Biomedical Research Excellence (INBRE) program. Another Idaho INBRE alum, Steve Van Horn, credits the program with enabling him to start a career in the pharmaceutical industry.
Providing undergraduate students with research opportunities and preparing them for STEM careers in biomedical sciences are key goals of INBREs across the country, including Idaho’s program. Here, we share Jenny’s and Steve’s stories and the pivotal role that INBRE played for them.

“If you want to pursue a career in science, it’s very important to foster a hardworking attitude, a creative mind, and critical thinking,” says Jingru Sun, Ph.D., an associate professor of translational medicine and physiology at Washington State University’s Elson S. Floyd College of Medicine in Spokane. Our interview with Dr. Sun highlights how her career path led her to research the way the nervous system regulates immune responses.
Q: How did you become interested in science?
A: In high school, I had an amazing teacher who introduced me to the scientific world, guided me to ask the right questions, and encouraged me to find answers by myself. I asked questions like: How do trees produce oxygen? How can we see bacteria through a microscope? Why are humans smarter than other animals?

“It would be a dream come true if I could look at a cell within a tissue and have a Google Maps view to zoom in until I saw individual molecules,” says Melike Lakadamyali, Ph.D., an associate professor of physiology at the University of Pennsylvania’s Perelman School of Medicine in Philadelphia. Her lab is helping make part of that dream a reality by developing super-resolution microscopy tools that visualize cells at a near-molecular level.
Blending Physics and Biology
Science and math fascinated Dr. Lakadamyali since childhood, and she felt especially drawn to physics because she enjoyed using logic to solve problems. After graduating high school in her native country of Cyprus, she chose to study physics at the University of Texas, Austin. She never gave much thought to applying physics methods to biological
questions—a field known as biophysics—until her third year as an undergraduate, when she gained her first research experience in the lab of Josef Käs, Ph.D.
In Other Words: Not All Tissues Are For Runny Noses
When most of us hear the word tissue, we think of something we reach for when we have a runny nose. But in biology, a tissue is a group of cells that act together to carry out a specific function.
Your body has four basic types of tissues:
- Muscle tissue provides movement. Types include voluntary muscles, like those in the arms and legs, and involuntary muscles, such as those that move food through the digestive system.
- Nervous tissue carries messages throughout the body and includes the brain, spinal cord, and nerves.
- Connective tissue supports other tissues and binds them together. Examples include ligaments, tendons, bones, and fat.
- Epithelial tissue creates protective barriers and includes the skin and the linings of internal passageways.
