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.
Researchers from Weill Cornell Medicine have found a fungus in the stomach of mice that may provide a clue to the evolution of fungi in the gastrointestinal tract.
An international group of researchers from FutureNeuro, the Research Ireland Centre for Translational Brain Science, and RCSI University of Medicine and Health Sciences have created a novel technique to characterize gene activity in the living human brain.
A recent breakthrough in biotechnology promises to change the landscape of plant genetic engineering. Imagine a persistent invader-;Agrobacterium-;long used to deliver genes into plants. Despite its historical success, the journey has been fraught with setbacks, especially with crops that launch fierce immune defenses.
Dynamic, reversible modifications of DNA and RNA regulate how genes are expressed and transcribed, which can influence cellular processes, disease development, and overall organismal health.
Working with week-old zebrafish larva, researchers at Weill Cornell Medicine and colleagues decoded how the connections formed by a network of neurons in the brainstem guide the fishes' gaze.
A recent study has decoded the complete genome of Forsythia suspensa, a plant renowned for its medicinal value and decorative appeal.
The hippocampus is one of the most fascinating brain regions. Associated with the formation of memories, it also helps us to navigate through the world without getting lost.
Findings on isoniazid-resistant M. tuberculosis reveal key vulnerabilities, suggesting new avenues for treatment strategies against drug-resistant tuberculosis.
Genes contain instructions for protein production, with the central dogma of biology stating that this information flows from DNA to RNA to proteins.
Genomic Informational Field Theory (GIFT) enhances genetic association detection, outperforming GWAS in mapping complex traits and subtle genetic interactions.
Biologging integrates sensors with wildlife research, enhancing understanding of animal physiology and ecosystem dynamics for improved conservation strategies.
With the support of a Maximizing Investigators' Research Award, or MIRA, from the National Institutes of Health, Michigan State University researcher Aleksandra Skirycz is making fundamental discoveries linked to the health and resilience of plants and animals.
Biologgers allow us to see with unprecedented precision how animals move and behave in the wild. But that's only part of the picture, according to a UC Santa Cruz ecologist renowned for using biologging data to tell the deeper story about the lives of marine mammals in a changing world.
A new method, developed by University of Michigan researchers, creates images that are worth many gigabytes of data, which could revolutionize the way biologists study gene expression. Seq-Scope, developed by Jun Hee Lee, Ph.D., Hyun Min Kang, Ph.D., and their colleagues, was first described in Cell in 2021 as the first method to analyze gene expression at sub micrometer-scale spatial resolution.
A living cell is a bustling metropolis, with countless molecules and proteins navigating crowded spaces in every direction.
Humans aren't the only ones who grow forgetful as they age -; fruit flies do, too. But because fruit flies have a lifespan of only about two months, they can be a useful model for understanding the cognitive decline that comes with aging.
To address childhood malnutrition -; which affects 200 million children globally -; researchers at Washington University School of Medicine in St. Louis developed a therapeutic food that nourishes the collections of beneficial microbes that reside in the gut, and improves children's growth and other measures of their health.
Using stem cells generated from patients with a rare and severe form of autism spectrum disorder and intellectual disability, Scripps Research scientists have grown personalized "mini-brains" (or organoids) to study the disorder in new detail.
Researchers from UAB and Iowa State University have produced the first-ever genome assemblies of two hidden-neck turtle species.
A multi-institutional group of researchers led by the Hubrecht Institute and Roche's Institute of Human Biology has developed strategies to identify regulators of intestinal hormone secretion.
