Aging is not simply the gradual passage of time. At the cellular level, it involves a collection of biological changes that influence how tissues repair themselves, how…

Aging is often described as a gradual decline in the body's ability to maintain and repair itself. As people grow older, the risk of cardiovascular disease, metabolic…

Healthcare has always generated information. A doctor listens to a patient's symptoms, examines the body, records observations, orders investigations, interprets test results, prescribes treatment and follows the…

For much of modern medicine, the idea of “normal” has been defined through populations. Blood pressure, cholesterol, blood glucose, heart rate, body mass index, laboratory measurements and…

For most of medical history, understanding a person's health depended on relatively occasional encounters with healthcare professionals. A patient described symptoms, a clinician performed an examination, laboratory…

Precision medicine began with an ambitious idea: healthcare should account for the biological differences between individuals rather than assuming that the same disease behaves identically in every…

The human body possesses a remarkable capacity for repair. Skin can close wounds, bones can remodel after injury, blood cells are continuously replaced, and tissues throughout the…

Three-dimensional bioprinting has emerged as one of the technologies attempting to address this challenge. Unlike conventional 3D printing, which typically deposits plastics, metals or other non-living materials,…

Medical research has traditionally depended on a combination of laboratory cell cultures, animal models, clinical observations, and human studies. Each approach has contributed enormously to scientific progress,…

Cancer diagnosis and monitoring have traditionally depended heavily on tissue biopsies, imaging, and laboratory testing. A tissue biopsy can provide valuable information because it allows pathologists to…
