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 method imitates how plants produce hormones

Plants produce the hormone jasmonic acid as a defense response when challenged. This is how they ensure that their predators no longer like the taste of their leaves.

New CRISPR-Cas9 based method for directed protein evolution

"Directed evolution" is the process by which scientists produce tailor-made proteins for cell biology, physiology and biomedicine in the laboratory.

New study outlines the mechanisms behind cell fusion

Scientists have known for a decade that cells that fuse with others to perform their essential functions - such as muscle cells that join together to make fibers - form long projections that invade the territory of their fusion partners.

Genetic 'memory' of ancestral homelands helps organisms adapt to environmental change

Organisms carry long-term "memories" of their ancestral homelands that help them adapt to environmental change, according to a new study that involved raising chickens on the Tibetan Plateau and an adjacent lowland site.

Bioelectrical engineering can help predict cell behavior

Humans use cells to regulate their body temperature, to breathe, to grow, and to perform several other day-to-day processes.

Eating Fish Reduces Risk Of Cardiovascular Disease

A study has found that consuming omega 3 primarily through fish, can modulate lipoproteins and can reduce the risk of cardiovascular disease.

New Functions Of A Protein May Improve Biocontrol Methods In Sustainable Agriculture

The laboratory of the UMA has proved that Bacillus subtilis cells, when deprived of an amyloid protein (TasA), exhibit a range of cytological anomalies.

A New Brick In The Wall: Bacterial Cell Wall Intermediate Found

An accumulation of the peptidoglycan recycling pathway that is able to modulate the synthesis and structure of the cell wall has been found by researchers.

Scientists study how brain cancer cells acquire radiation resistance

In a vertical climb to avoid collision with a towering mountain, a plane ejects cargo to gain altitude. Investigators at the University of Minnesota showed that cancer cells perform similar feats in escaping the killing effects of radiation.

Study shows the dual role of amyloid proteins in Bacillus physiology

When Bacillus subtilis cells are deprived of an amyloid protein, they show a range of cytological dysfunctions and anomalies that cause their premature death.

Different Kinds Of White Fat Are Important In Disease

Excess white fat causes obesity, which in turn can drive metabolic diseases that are growing at epidemic rates around the world.

High-Fat Diet Consequences Include Mental Fatigue, Researchers Say

Obesity has been shown to place physical stress on the body, but new research suggests that excess weight may also cause mental fatigue.

Reference genes could lead to genetic improvement in wheat

Wheat sustains the world. The FAO has stated that wheat is one of the main crops in the world, both in terms of scope and production, and it is also one of the rich sources of vegetable protein and carbohydrates in the human diet.

Study reveals the formation of tuft cells and their role in immunity

Chronic pancreatitis, or persistent inflammation of the pancreas, is a known risk factor that leads to the development of pancreatic cancer, which is the third-deadliest cancer in the United States.

Sensitive technique makes it possible to study the delivery of RNA drugs

In recent years, RNA molecules, with the ability to affect or turn off pathogenic genes, have become promising drug candidates in several areas.

Computer Model Predicts How Drugs Affect Heart Rhythm

UC Davis Health researchers have developed a computer model to screen drugs for unintended cardiac side effects, especially arrhythmia risk.

Plant genes control microbiome diversity inside leaves to stay healthy

In a new study, published in the journal Nature, Michigan State University scientists show how plant genes select which microbes get to live inside their leaves in order to stay healthy.

Clock protein moves in sync with temperature to coordinate rhythms in shoots, roots

Five years ago, researchers from the Centre for Research in Agricultural Genomics led by the CSIC Research Professor Paloma Mas made the breakthrough discovery that the circadian clocks in the growing tip of the plant shoot function in a similar way to the clocks in the mammalian brain, which in both cases are able to synchronize the daily rhythms of the cells in distal organs.
