Aging has long been viewed as an unavoidable decline that begins later in life, gradually reducing physical and cognitive abilities. However, modern biomedical science is transforming this perspective. Researchers now recognize aging as a lifelong biological process that can be influenced and potentially modified through scientific intervention.

Advances in metabolic, cellular, and molecular research are revealing new opportunities not only to increase lifespan, but also to improve healthspan — the number of healthy, active years a person lives. At the forefront of this emerging field is Duke University School of Medicine, where scientists and clinicians are driving innovations aimed at promoting healthier aging through research, clinical care, and interdisciplinary collaboration.

According to Heather Whitson, aging is not limited to late adulthood but begins even before birth, continuing through ongoing molecular and cellular changes across the lifespan. Understanding these processes may allow researchers to design interventions capable of slowing or even reversing aspects of biological aging.

Whitson collaborates with Christopher Newgard and Manesh Patel to integrate Duke’s expertise in research, education, and patient care into a unified approach focused on extending healthy years of life. Duke’s leadership in aging science is supported by its internationally recognized research centers, including the Duke Center for the Study of Aging and Human Development, the Duke-UNC Alzheimer’s Disease Research Center, and the Duke Claude D. Pepper Older Americans Independence Center.

A major strength of Duke’s approach is its emphasis on interdisciplinary collaboration. Experts in cardiovascular health, neurodegeneration, metabolism, nutrition, orthopaedics, and related fields are working together to better understand how aging affects interconnected systems throughout the body. This integrated model aims to create evidence-based strategies that support long-term wellness and disease prevention.

Researchers at Duke also emphasize that age should not only be measured chronologically, but biologically. While chronological age reflects the number of years lived, biological age measures how quickly the body’s systems are aging at the cellular level. Scientists such as Avshalom Caspi and Terrie Moffitt have contributed significantly to this field through the development of DunedinPACE, an advanced epigenetic clock designed to measure the pace of biological aging more accurately.

This evolving understanding of aging is reshaping medicine and creating new possibilities for improving quality of life across the human lifespan.
