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.

Scientists discover brain's 'future map'

Researchers from the RIKEN Center for Brain Science (CBS) in Japan have discovered a region of the brain that encodes where an animal is planning to be in the near future. Linked to internal maps of spatial locations and past movements, activity in the newly discovered grid cells accurately predicts future locations as an animal travels around its environment. Published in Science on August 15th, 2024, the study helps explain how planned spatial navigation is possible.

Columbia study reveals bacteria create free-floating genes, challenging genetic code norms

Since the genetic code was first deciphered in the 1960s, our genes seemed like an open book. By reading and decoding our chromosomes as linear strings of letters, like sentences in a novel, we can identify the genes in our genome and learn why changes in a gene's code affect health.

High BPA levels linked to increased prostate cancer risk in older men

A study in Nutrients found that higher urinary bisphenol A (BPA) levels are linked to increased prostate-specific antigen (PSA) and higher prostate cancer risk in senior American men. This suggests a need for heightened cancer screening, especially in high-risk groups.

How C. elegans uses smell to preemptively guard against pathogen attacks

Many organisms react to the smell of deadly pathogens by reflexively avoiding them. But a recent study from the University of California, Berkeley, shows that the nematode C. elegans also reacts to the odor of pathogenic bacteria by preparing its intestinal cells to withstand a potential onslaught.
