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 mathematical model captures forces involved in cell movement

Physicists have teamed up to find out the precise mechanisms that play a crucial role in cell motility.

Gene therapy helps paralyzed mice to walk again

For the first time, scientists have successfully used gene therapy to make mice walk again after these animals suffered a complete cross-sectional injury.

Study identifies gene networks that control sugar and organic acid metabolism during fruit development

The watermelon and melon cultivation project by researchers achieved a new advancement in controlling the metabolism of sugar in watermelon fruit.

Study reveals richness of space-time gene expression dynamics of the liver

Nothing in biology is static. Biological processes fluctuate over time, and if we are to put together an accurate picture of cells, tissues, organs etc., we have to take into account their temporal patterns. In fact, this effort has given rise to an entire field of study known as "chronobiology".

Researchers show how the genetic material travels from cell to cell

The genetic material of plants, animals, and humans is well protected in the nucleus of each cell and stores all the information that forms an organism. For example, information about the size or color of flowers, hair or fur is predefined here.

Researchers discover protein crucial for growing life-saving blood stem cells

A group of scientists from the Centre for Genomic Regulation (CRG) in Barcelona and Columbia University in New York City has discovered a protein that is crucial for expanding the usually scarce, life-saving blood stem cells.

Scientists aim to treat and prevent disease by understanding exercise benefits

A top exercise researcher and colleagues at the University of Virginia School of Medicine have launched an ambitious effort to understand the whole-body benefits of exercise so that doctors can use that information to prevent and treat disease.

Subspace mass spectrometry imaging method can accelerate speed of data acquisition

A new computational mass spectrometry imaging method enables researchers to achieve high mass resolution and high spatial resolution for biological samples while providing data sets exponentially faster.

Changes to oral microbiota affect the cardiovascular benefits of sport

Exercise plays a key role in maintaining good physical and mental health throughout life. There is an increasing amount of scientific evidence that some of the immune system and metabolism benefits provided by sport are related to the thousands of millions of bacteria that colonize the digestive tract, from the mouth to the intestines, known as microbiota.

New molecular imaging strategy helps observe the sperm selection process

A protein called CatSper1 may act as a molecular 'barcode' that helps determine which sperm cells will make it to an egg and which are eliminated along the way.

Research shows lipogenesis process is dysregulated in obesity, fatty liver disease

The production of fat in the human body is essentially regulated by gut hormones.

Eating dried fruits may be linked with better health

Don't be afraid to toss a handful of raisins or dried apples in your Thanksgiving stuffing this year -- a new Penn State study has found that dried fruit may be connected with better health.

Hormone that suppresses food intake could help tackle obesity

A hormone that can suppress food intake and increase the feeling of fullness in mice has shown similar results in humans and non-human primates, says a new study published today in eLife.

High-protein total diet replacements may be a promising strategy to combat obesity

According to the World Health Organization, obesity has nearly tripled worldwide since 1975. In 2016, for example, more than 1.9 billion adults were categorized as overweight. Of these, more than 650 million had obesity.

Researchers develop new method to produce artificial organelles in living yeast cells

Cells of higher organisms use cell organelles to separate metabolic processes from each other. This is how cell respiration takes place in the mitochondria, the cell’s power plants.

CRISPR technique reveals genes that regulate physiological, behavioral changes

In social hierarchy, rank is a condition that is not exclusively claimed by human beings. In the animal world, male peacocks have vividly colored plumes to show dominance, while underwater, male fish exhibit an array of vivid colors to do the same.

A stepwise approach to increase crop yield

GAIN4CROPS is developing novel disruptive technologies to overcome one of the main constraints of photosynthesis: the photorespiration, a process that reduces CO2 assimilation efficiency, and thus biomass yield and agricultural productivity.

Researchers study the impact of global warming on phytoplankton

Understanding the impacts of global warming on phytoplankton- the foundation of marine ecosystems -is critical to predicting changes in future biodiversity, ocean productivity, and ultimately fisheries production.

Similarities between animal and plant immune systems go beyond sensing

Max Planck Institute for Plant Breeding Research (MPIPZ) and University of Cologne researcher Takaki Maekawa and colleagues have discovered that plants have independently evolved a family of immune proteins that are strikingly similar to animals.

Specific metabolites can predict COVID-19 mortality

A new study from Lawson Health Research Institute, Western University and University of Alberta suggests that COVID-19 affects the human body's blood concentration levels of specific metabolites - small molecules broken down in the human body through the process of metabolism.
