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 discover signaling pathway that can regulate beige fat thermogenesis

Researchers have discovered a new set of signals that cells send and receive to prompt one type of fat cell to convert fat into heat.

Study uncovers two brain phenomena that may explain ketamine's side-effects

Researchers have identified two brain phenomena that may explain some of the side-effects of ketamine. Their measurements of the brain waves of sheep sedated by the drug may explain the out-of-body experience and state of complete oblivion it can cause.

Study reveals structure of an activated dopamine receptor

Dopamine, a chemical that sends messages between different parts of the brain and body, plays a key role in a variety of diseases and behaviors by interacting with receptors on cells.

'Fat burning' molecule holds promise for future treatment and prevention of obesity

Obesity affects more than 40 percent of adults in the United States and 13 percent of the global population.

New model decodes relationship between metabolic mechanisms and genes

New research introduces a unique mathematical method to study human metabolism by decreasing the complexities of the human genome-scale GEMs.

Study identifies gene responsible for eye loss in cavefish

Mexican cavefish spend their entire lives in the dark. With no need for vision, many of them lost functional eyes.

Stem cell model sheds new light on neurodegeneration process

A new study published today in Neuron led by The New York Stem Cell Foundation Research Institute's Valentina Fossati, Ph.D., creates astrocytes - an integral support cell in the brain - from stem cells and shows that in disease-like environments, these normally helpful cells can turn into neuron-killers.

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.
