Physiology is the study of how the body works under normal conditions. We use physiology when we exercise, read, breathe, sleep, eat, move, or do just about anything.

In this section you will learn "what’s new?" in human and animal physiology.  Our information comes directly from the new scientific discoveries published in our research journals and presentations made by our members and other scientists at our meetings.

We explain physiology for the non-scientist through:

Press Releases and Announcements

Archive of Teaching Resources Relaunches As Life Sciences Teaching Community

Released April 8, 2014 - New community offers thousands of free resources for life science educators. The Physiological Society, Genetics Society of America, and American Society of Plant Biologists join as scientific society partners.

Race Now or Later? Calculating the Best Time to Compete after Altitude Training

Released April 3, 2014 - In a new review article, researchers explore the ideal time to return to sea level and compete following training at high altitude. The research is one of 15 articles on hypoxia—this month’s highlighted topic in the Journal of Applied Physiology.

A Protein Could Be a Key Weapon in the Battle of the Bulge

Released April 1, 2014 - In a new study, researchers found that elevated levels of GDNF protein could help fight the weight gain and health problems associated with a high-fat diet. The article is published in AJP-Gastro and was chosen as one of April's APSselect articles.

EB Attendees: Save Time for Communication!

2014 APS Communications Symposium: Author and scientist-turned-filmmaker Randy Olson, PhD, will present the interactive session “Storytelling: Mandatory Training for Today’s Scientists.”

Not Only Is She Thinner Than You…Her Muscles Work Better, Too

Released March 20, 2014 - In a new AJP-Endo study, researchers examined how muscle physiology plays into being and staying lean.

Genes May Thwart Seniors’ Exercise Gains

Released March 14, 2014 - A new study in Physiological Genomics examines the ACE I/D gene and how its variations -- the ID, DD, and II genotypes -- cause some seniors' to lose out on the benefits of exercise.

APS Elects New 2014 Officers

Released February 25, 2014 - APS announces its newly-elected officers for 2014. Patricia E. Molina, MD, PhD is the new president-elect. Barbara Alexander, PhD; Rudy M. Ortiz, PhD; and Bill Yates, PhD have been named to the APS Council.

The American Physiological Society Launches APSselect

Released January 31, 2014 - January 2014 marks the beginning of an exciting new initiative for the Society. Our new virtual journal, entitled APSselect, will highlight the “best of the best” of the some 250 papers published each month by the Society’s 10 research journals.

“The Sex of Cells” in the Lab

Released January 2, 2014 - At first glance one might think that a cell lacks features that would reflect its sex or gender. In fact, that is not true. Researchers are now discovering that the sex of experimental subjects—even cells—does matter in research.

Fetal Alcohol Syndrome Heart Defects May Be Caused by Altered Function, Not Structure

Released December 30, 2013 - Study utilizing using animal model finds fetal alcohol syndrome (FAS) heart defects may be caused by altered function, not structure.

For Altitude Training, a Narrow Window for Success

Released December 12, 2013 - In a new study, researchers found that living between 2000 and 2500 meters above sea level offered the best performance enhancement compared to living at higher or lower elevations. These findings could help competitive endurance athletes and their coaches develop altitude training regimens that have the highest chance of success.

Quadriplegics at Risk for Serious Sleep Breathing Disorder

Released December 5, 2013 - New findings suggest that where the spinal cord is injured—in the neck, or lower—can affect the likelihood and type of breathing problems during sleep, including central sleep apnea. Understanding how and why patients’ nighttime breathing is affected could help doctors better manage these conditions.

For Obese Teen Girls, Aerobic Exercise May Trump Resistance Training

Released November 7 2013 - New findings suggest that for teen girls, aerobic exercise might be superior to resistance exercise for cutting health risks associated with obesity. Study published in the American Journal of Physiology-Endocrinology and Metabolism.

Vitamin C Could Ease Muscle Fatigue in COPD Patients

Released November 7, 2013 - New findings show IV infusions of vitamin C can improve skeletal muscle fatigue in COPD patients, further implicating the role of oxidative stress in the skeletal muscle problems that accompany the disease.
