Human physiology is the science of the mechanical, physical, and biochemical functions of humans in good health, their organs, and the cells of which they are composed. The principal level of focus of physiology is at the level of organs and systems. Most aspects of human physiology are closely homologous to corresponding aspects of animal physiology, and animal experimentation has provided much of the foundation of physiological knowledge. Anatomy and physiology are closely related fields of study: anatomy, the study of form, and physiology, the study of function, are intrinsically tied and are studied in tandem as part of a medical curriculum.
Essay challenges the scientific validity of the Blue Zones concept and Ancel Keys’ Lipid Hypothesis, arguing that both rest on biased data, weak records, and methodological flaws. The authors say some longevity claims may reflect clerical errors, poverty, and unreliable vital records rather than uniquely healthy lifestyles.
Obesity alters bone health not only through increased body weight but also by reshaping the bone marrow environment.
Myofibrillar myopathy type 6 (MFM6) is a rare genetic muscle disorder that leads to severe muscle weakness and a drastically shortened life expectancy due to a disruption in muscle protein regulation.
Coffee consumption influences the microbiota-gut-brain axis, affecting cognitive performance and emotional regulation through complex biological pathways.
An experimental drug targeting triple-negative breast cancer overwhelms cancer cells with toxic fats, according to new tests on human-derived tumors in mice.
A study in Pediatric Investigation found that rural and urban children and adolescents tend to experience different mental health issues, with those living in the country showing more emotional problems and those in the city demonstrating more behavioral issues.
Researchers had previously discovered a population of immune cells within the brain that can act as accelerators and brakes for anxiety in mice. N
Depending on whom you ask, Alfred Engelberg could be a hero or a villain in the story of American pharmaceuticals.
This review examines how high-throughput proteomics is expanding precision medicine by improving biomarker discovery, disease prediction, and drug development. It also shows how AI is helping researchers interpret complex proteomic data while highlighting major barriers such as standardization, validation, and clinical translation.
Researchers from the University of Bonn and University Hospital Bonn uncover vital mechanism for survival
Hamstring injuries are among the most common injuries in sports, particularly in activities involving sprinting and rapid acceleration. They account for roughly 10 % of injuries in field-based sports and often result in significant time away from competition. Despite their frequency, the mechanisms underlying the effectiveness of certain training programs in preventing these injuries remain poorly understood.
Fibroblasts are an essential component of the heart, as they play key roles in its structure, development and response to cardiac damage.
A team of scientists from Nanyang Technological University, Singapore (NTU Singapore) has developed a new biochip that, when paired with Artificial Intelligence (AI), can detect quickly and accurately extremely small amounts of microRNAs, which are tiny genetic markers linked to diseases such as heart disease.
The Damon Runyon Cancer Research Foundation has named 13 new Damon Runyon Fellows, exceptional postdoctoral scientists conducting basic and translational cancer research in the laboratories of leading senior investigators.
New research from the University of Maryland, Baltimore County (UMBC) reveals how two different parts of the brain's memory center team up in a key reward region to help mice-and likely humans-combine memories of places and contexts with the drive to pursue rewards.
The editorial, "Dynamics-driven medical big data mining: dynamic approaches to early disease forecasting and individualized care," published in Intelligent Medicine (February 2026, Volume 6, Issue 1), was written by Lu Wang (Tianjin Medical University), Han Lyu (Beijing Friendship Hospital, Capital Medical University), and Bin Sheng (Shanghai Jiao Tong University).
With a new model of the brain region essential to memory formation, from cells to whole-brain networks, the team hopes to identify critical changes in the progression of Alzheimer's disease that could point the way to earlier, more effective treatments.
Sauna bathing releases white blood cells into the bloodstream, a new study from Finland shows. Circulating white blood cells play a key role in the body's defense against various pathogens and diseases.
Researchers at the Tata Institute of Fundamental Research (TIFR), Hyderabad, have identified a mammalian protein, Cnpy1 (Canopy1), that is essential for the survival and function of vomeronasal sensory neurons in mice.
Some of your most important life partners are the mitochondria that power all your cells. You and these little cellular powerhouses are in a 1.5-billion-year-old evolutionary relationship-but mitochondria brought some baggage.
