Happy International Women's Day 2025!
On this International Women's Day, BioInsight DNA & Blood Services would like to honor the contributions of women in science. Beyond Marie Curie, there have been myriad women who have contributed to science, in general, and biomedical science, in particular. There are women in research laboratories, medical laboratories, and epidemiologic laboratories all across the world.
In biomedical research, one of the most transformative fields in science, the contributions of women have significantly shaped the research. From uncovering the molecular underpinnings of diseases to developing life-saving treatments, women in biomedical research have made monumental strides in improving human health. Their work not only furthers our understanding of complex biological systems but also provides solutions to some of the most pressing global health challenges.
1. Marie Maynard Daly: A Pioneer in Cardiovascular Health
In the mid-20th century, Marie Maynard Daly broke barriers as the first African American woman to earn a Ph.D. in chemistry in the United States. Daly’s groundbreaking research focused on the relationship between high blood pressure, cholesterol, and the development of atherosclerosis—conditions that are now recognized as major risk factors for heart disease. Her work helped establish a scientific understanding of how fatty deposits in the arteries can impede blood flow, leading to cardiovascular diseases, which remain the leading cause of death worldwide.
Daly’s research also shed light on the importance of a balanced diet and the role of the body’s enzymes in regulating metabolic processes. Her work laid the foundation for preventive medicine and has had far-reaching implications in nutrition and public health.
2. Linda Buck: Revolutionizing the Sense of Smell
Linda Buck is one of the most influential figures in the field of neuroscience. She won the Nobel Prize in Physiology or Medicine in 2004, alongside Richard Axel, for their work on the genetic and molecular basis of the sense of smell. Buck’s research demonstrated that the human nose is capable of detecting a wide array of scents through the activation of specific receptors in the olfactory system.
Her discoveries have had far-reaching implications beyond the study of olfaction. By unlocking the mystery of how the brain processes scents, Buck’s work has expanded our understanding of sensory systems and the brain’s ability to interpret environmental stimuli. Additionally, her research has contributed to fields such as neurodegenerative diseases, where impairments in sensory perception are often early warning signs of conditions like Alzheimer's and Parkinson’s disease.
3. Frances Arnold: Engineering Enzymes for Medicine and Sustainability
In the field of chemistry and biochemistry, Frances Arnold made a transformative contribution through her pioneering work in the development of enzyme engineering, for which she was awarded the Nobel Prize in Chemistry in 2018. Her research focused on creating enzymes through a process called directed evolution, which mimics the principles of natural selection to produce new, more efficient enzymes.
This work has had profound implications for medicine, particularly in the creation of more sustainable pharmaceutical processes. Engineered enzymes are now used in the production of drugs, diagnostics, and biofuels. Arnold’s work has revolutionized green chemistry, making processes more environmentally friendly and cost-effective. Her contributions have opened up new avenues for biotechnological innovations that have applications in everything from cancer treatment to sustainable agriculture.
4. Katalin Karikó and Drew Weissman: Foundational Work Behind mRNA Technology
One of the most extraordinary contributions by women in biomedical research in recent years is the development of mRNA vaccine technology, which became the cornerstone of the rapid response to the COVID-19 pandemic. Katalin Karikó, a Hungarian-born biochemist, and Drew Weissman, an immunologist, spent decades researching the potential of mRNA as a therapeutic tool. Their research, which focused on the stabilization and delivery of mRNA without triggering immune responses, led to the breakthrough technology that allowed the rapid development of effective vaccines against COVID-19.
Karikó and Weissman’s work laid the foundation for the development of the Pfizer-BioNTech and Moderna COVID-19 vaccines, which have saved millions of lives globally. Their discovery is a prime example of how perseverance, collaboration, and a commitment to scientific inquiry can result in groundbreaking advancements with profound global impact. The mRNA platform is now being explored for use in other areas of medicine, including cancer vaccines and gene therapies, promising to revolutionize the treatment of many diseases.
5. Elizabeth Blackburn: Unraveling the Secrets of Telomeres and Aging
Elizabeth Blackburn, an Australian-American biologist, was awarded the Nobel Prize in Physiology or Medicine in 2009, alongside Carol Greider and Jack Szostak, for their discovery of the enzyme telomerase and its role in maintaining the length of telomeres—the protective caps at the ends of chromosomes. Blackburn’s work has had far-reaching implications for aging and cancer research. Telomeres shorten each time a cell divides, and when they become too short, the cell can no longer divide and becomes senescent, which is linked to aging and the development of age-related diseases.
Blackburn’s discovery has led to a better understanding of cellular aging and the role of telomerase in preventing telomere shortening. Her research opened new avenues for investigating how we might slow aging, promote healthier aging, and even find therapies to prevent diseases like cancer, where telomere maintenance is often disrupted.
6. Jennifer Doudna: The CRISPR Revolution
While her work is most well-known in the field of gene editing, Jennifer Doudna’s contributions to biomedical research have far-reaching implications. As a co-discoverer of the CRISPR-Cas9 gene-editing technology, Doudna has revolutionized the way scientists approach genetic modification. The CRISPR system allows precise edits to the DNA of living organisms, enabling groundbreaking work in medicine, agriculture, and biotechnology.
The potential of CRISPR in treating genetic diseases such as sickle cell anemia, cystic fibrosis, and muscular dystrophy is enormous. Doudna’s pioneering work has not only reshaped the landscape of genetic engineering but has also sparked important ethical debates surrounding gene editing, cloning, and human genetics, challenging scientists, policymakers, and society to consider the broader implications of this powerful technology.
7. The Broader Impact of Women in Biomedical Research
The work of women in biomedical research extends beyond the breakthroughs that have directly impacted treatments and therapies. Their contributions shape the way science is conducted, the way research is funded, and the way we think about public health and social justice. Many female researchers advocate for more equitable funding and representation in science, pushing for diversity in clinical trials and medical research to ensure that discoveries benefit all populations, regardless of gender, race, or socioeconomic status.
Women in biomedical research continue to inspire future generations of scientists and health professionals. They show that science is a collaborative, interdisciplinary field where diverse perspectives are essential for addressing complex health challenges. As more women take on leadership roles in research and policy, we can expect even more transformative advances that will benefit global health.
Conclusion
Women have played—and continue to play—a pivotal role in biomedical research, shaping the course of human health and medicine. From advancing our understanding of molecular biology to developing innovative therapies, the contributions of women in this field have been integral in solving some of the most complex challenges facing humanity. As we look ahead, the ongoing work of women in biomedical research promises even greater breakthroughs in health care, with the potential to save lives, extend lifespans, and improve the quality of life for people around the world.
