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.

Sucrose Acts as a Signal Transmitter for Light-Dependent Root Architecture Formation in Arabidopsis

Plant growth is driven by light and supplied with energy through photosynthesis by green leaves. It is the same for roots that grow in the dark – they receive the products of photosynthesis, in particular sucrose, i.e. sugar, via the central transportation pathways of phloem.

New Insights Into How Genetic Variants Impact Gene Expression

The Department of Biomedical Informatics (DBMI) at the University of Colorado School of Medicine, in collaboration with the University of California San Francisco and Stanford University, has recently published a study that is the largest of its kind to focus on ancestry correlations with biomedical traits.

Climate Change is Altering Hibernation Patterns of Arctic Ground Squirrels

Arctic ground squirrels are unique among mammals. Their ability to keep from freezing even when body temperatures dip below that mark on the thermometer enables them to survive extreme winter climates.

Researchers Develop AI Method to Predict Small Molecule Substrates of Enzymes

Enzymes are the molecule factories in biological cells. However, which basic molecular building blocks they use to assemble target molecules is often unknown and difficult to measure.

Key Event that Controls the Timing of the Biological Clock Identified

Molecular clocks in our cells synchronize our bodies with the cycle of night and day, cue us for sleep and waking, and drive daily cycles in virtually every aspect of our physiology. Scientists studying the molecular mechanisms of our biological clocks have now identified a key event that controls the timing of the clock.

Researchers Examine the Role of TOR in LR Formation and its Interplay with Auxin Signaling

Along with sugar reallocation, a basic molecular mechanism within plants controls the formation of new lateral roots. An international team of plant biologists has demonstrated that it is based on the activity of a certain factor, the target of rapamycin (TOR) protein. A better understanding of the processes that regulate root branching at the molecular level could contribute to improving plant growth and therefore crop yields, according to research team leader Prof. Dr Alexis Maizel of the Centre for Organismal Studies at Heidelberg University.

Study Demonstrates the First Molecular Link Between Circatidal and Circadian Clocks

Scientists at UMass Chan Medical School and the Marine Biological Laboratory at Woods Hole have identified the first gene-; Bmal1-; to play a crucial role in regulating circatidal behavior in the crustacean Parhyale hawaiensis.

Scarring on the Extracellular Matrix Causes Muscles to Stop Working in Duchenne Muscular Dystrophy

Muscles that ache after a hard workout usually don't hurt for long, thanks to stem cells that rush to the injured site along "collagen highways" within the muscle and repair the damaged tissue.

High-Throughput Technique Observes Differences in Hard and Non-Hard Seeds

Alfalfa (Medicago sativa), also known as the “King of Grass,” is a legume cultivated in various parts of the world for animal feed. It is highly valued in the feed business because of its high protein content and biomass output.

STING-seq Discovers Causal Variants and Genetic Mechanisms for Blood Cell Traits

A major challenge in human genetics is understanding which parts of the genome drive specific traits or contribute to disease risk. This challenge is even greater for genetic variants found in the 98% of the genome that does not encode proteins.

Csx28 Membrane Protein Enhances CRISPR's Anti-Viral Defense

CRISPR achieved scientific popularity for its capacity to quickly and precisely edit genes. At the core, however, CRISPR systems are immune systems that aid bacteria to safeguard themselves from viruses through targeting and abolishing viral RNA and DNA.
