Scientists develop synthetic mucus to control pathogenic bacteria and maintain healthy microbial balance in the body. The study reveals mucins can help prevent diseases by reducing dominance of harmful species.
Researchers found that walking significantly increases blood flow to the brain, comparable to running, but less dramatic than cycling. The study uses non-invasive ultrasound to measure internal carotid artery blood velocity waves and arterial diameters.
Researchers found that orange essential oil reduced fear responses and diminished immune system markers of stress in mice, suggesting a potential nonpharmaceutical option for PTSD. The study's findings hint at a possible mechanism for the effects of essential oils on brain gene expression.
Researchers can extract proteins from 80-million-year-old dinosaur bones, providing information on evolution, biomaterials, and potential applications for drug development. The study also explores the age and environment of samples, as well as the functions of ancient proteins.
Researchers develop nanosponges that capture and inactivate bacterial toxins, reducing cellular damage and disease severity. The new approach shows promise as a treatment for severe or antibiotic-resistant streptococcal infections.
A new mouse study found that exposure to a high-fat diet in the womb and immediately after birth may increase offspring risk for nonalcoholic fatty liver disease later in life. The offspring of pregnant mice that consumed a high-fat diet developed liver fibrosis, a type of tissue scarring that is a sign of more serious disease.
New research examines how genetics contribute to the metabolism of synthetic cannabinoids, increasing risk for severe effects. Understanding this connection could lead to targeted treatments and antidotes.
Rats that experience past episodes of limited food resources develop physiological adaptations to conserve energy and survive prolonged starvation. Researchers found that starved rats have lower body temperatures and blood sugar levels than fed controls, allowing them to hold onto stored fat for energy.
A new study finds that the duration and timing of school lunch and recess affect food choices and physical activity in children. Research suggests that scheduling recess before lunch reduces food waste, but may lead to consuming more vegetables when lunch is offered first, and increased physical activity during longer combined periods.
Researchers have discovered that altered immune cells activated by placental ischemia can exacerbate preeclampsia symptoms. However, deleting these cells in animal models of the condition reduces hypertension, inflammation, and fetal growth restriction.
Researchers analyze amino acid stability under various extraterrestrial conditions, including temperature, pH, and radiation, to identify potential building blocks of alien life. The study aims to find structural characteristics that lead to higher stability in these conditions.
A new study by Dara Orbach, PhD, uses computed tomography scans and silicone models to visualize the anatomy of dolphin copulation. The research reveals complex vaginal folds and spirals that interact with the penis during fertilization.
The star-nosed mole possesses an extremely efficient nervous system that enables it to identify and eat food in under 2 seconds. Its distinctive star organ contains over 100,000 nerve fibers, making it the most sensitive known touch organ in any mammal.
Researchers discovered carvedilol's protective effect against UVB-induced cell damage that leads to skin cancer. The study suggests carvedilol could be incorporated into a skin cream or spray to prevent skin cancer.
A new study reveals that genetic variations affect eating behaviors and food preferences in healthy individuals. Researchers found associations between specific genes and intake of chocolate, vegetables, fiber, salt, and fat.
Researchers have made groundbreaking advances in understanding how food affects our bodies and make healthy choices. Dark chocolate has been shown to reduce oxidative stress and improve memory, while cinnamon activates an enzyme that regulates blood sugar levels.
Scientists have made significant breakthroughs in cardiovascular research, including the use of neuroprosthetics to restore heart function in patients with spinal cord injuries. Researchers also created patient-specific mitral valve models using 3-D printing to help surgeons personalize their approach and improve patient outcomes.
New methods for detecting breast cancer in young women using breastmilk, targeting G protein-coupled receptors to develop cancer drugs, and exploring the effects of dried plums on colon health offer promising approaches to combat cancer.
Researchers have made significant discoveries on treating obesity and related health issues, including a potential new treatment for weight loss. A mouse study found that avoiding foods high in methionine may be as effective as long-term restriction in promoting weight loss and improving blood sugar levels. Additionally, studies sugges...
The American Physiological Society's (APS) Porter Physiology Development Fellowship has supported 140 minority doctoral and postdoctoral researchers in the study of physiological sciences. Since its inception in 1967, the program has increased diversity in physiology and within APS membership.
The American Physiological Society has announced its 2017 Distinguished Lecturers, who will present talks at Experimental Biology. The winners include Michael J. Welsh, Brant Isakson, and Kurt Albertine, recognized for their lifetime achievement and contributions to physiology.
