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.

New heart rate measure offers clues to future cognitive health

Healthy hearts are adaptable, and heartbeats exhibit complex variation as they adjust to tiny changes in the body and environment.

New insights into bacterial division through engineered protein control

The Min protein system prevents abnormal cell division in bacteria by forming oscillating patterns between the ends of a cell ("poles"). Despite decades of theoretical work, predicting the protein concentrations at which oscillations start and whether cells can maintain them under different conditions has been a challenge.

Obesity changes how the gut responds to plant compounds, researchers report

Researchers found that the impact of polyphenols rutin and genistein on the human fecal metabolome varies significantly by body mass index (BMI). Lower BMI individuals showed more diverse metabolic responses, revealing how gut health and obesity could shape polyphenol metabolism.

Why your heart works harder at night after a few drinks, according to new research

Researchers at Ludwig Maximilian University of Munich found that moderate alcohol consumption transiently raises nocturnal resting heart rate without altering objective sleep stages. However, it worsens subjective sleep quality, highlighting subtle cardiovascular stress even at low alcohol doses.

Study illuminates a general principle of neural processing in the brain’s serotonin system

Our lives are filled with binary decisions – choices between one of two alternatives. But what's really happening inside our brains when we engage in this kind of decision making?

Muscle building unaffected by vegan or animal-based protein sources

A new study asked three questions about muscle protein synthesis in response to a nine-day diet and weight training regimen: First, does the source of protein - plant or animal-based - make any difference to muscle gain? Second, does it matter if total daily protein intake is evenly distributed throughout the day? And third, does a moderate but sufficient daily protein intake influence any of these variables? The answer to all three questions is "no," the researchers found.
