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.

ORNL Scientists Develop Fluorescent Biosensor to Track RNA in Plants

Scientists at Oak Ridge National Laboratory have developed a first-ever method of detecting ribonucleic acid, or RNA, inside plant cells using a technique that results in a visible fluorescent signal.

PanK4 Protein Could Be Key to Better Control of Blood Sugar and Metabolism

Physical activity is not only important for fitness, but also for health. This is confirmed by a new study conducted under the direction of Prof. Dr. Maximilian Kleinert at the German Institute of Human Nutrition Potsdam-Rehbrücke (DIfE). His team discovered that the protein PanK4 plays a crucial role in the energy metabolism of skeletal muscles.
