A pioneering new study published in Nature Microbiology, led by J. Oriol Sunyer, professor of immunology and pathobiology at the School of Veterinary Medicine, and a team of researchers at Penn Vet and the University of New Mexico, has uncovered a surprising new player in gut health: an antibody called secretory immunoglobulin M (sIgM).

While another antibody, secretory immunoglobulin A (sIgA), has long been known for helping balance the bacteria in our intestines, this new research shows that sIgM may be just as vital—if not more so—in protecting gut health and maintaining overall well-being.

Capital Medical University, in collaboration with the Chinese Academy of Sciences, reports that betaine, a molecule produced in the kidney and enhanced through sustained exercise, operates as a potent inhibitor of inflammatory and aging-related pathways.

Regular physical activity boosts health across cardiovascular, metabolic, and neurological systems. Scientists have traced improvements in immune function, insulin sensitivity, clearing of senescent cells and tissue regeneration to consistent physical activity. Earlier animal studies suggested that long-term exercise can delay aging processes and reduce vulnerability to chronic disease.

Precise molecular explanations for how sustained exercise reshapes human biology remain incomplete...

Research led by the National Institute of Biological Sciences in Beijing has discovered that switching on a single dormant gene enables mice to regenerate ear tissue.

Some vertebrates such as salamanders and fish can regenerate complex tissue structures with precision. A lost limb can be regrown, a damaged heart or eye can be repaired. Salamanders are so remarkable at reconstructing damaged tissues that even a spinal cord injury with severed neural motor connectivity can be restored.

Mammals occasionally showcase the ability to regenerate. Deer antlers and goat horns are examples of living tissue regeneration. Mice can regrow fingertips if they are lost. A healthy human liver can experience up to 70% loss of tissue and regrow to near full size within several weeks.

However, f...

USC researchers have developed a groundbreaking ultrasound device that could reduce our reliance on addictive painkillers. A groundbreaking wireless implant promises real-time, personalized pain relief using AI and ultrasound power no batteries, no wires, and no opioids. Designed by USC and UCLA engineers, it reads brain signals, adapts on the fly, and bends naturally with your spine.

Chronic pain is a debilitating condition that severely impacts quality of life, often leading to reliance on opioid medications with their severe side effects and addiction risks. According to the U.S. Pain Foundation, 51.6 million Americans live with chronic pain. For over 17 million sufferers, their chronic pain is high-impact – frequently limiting their life or work activities.

Current implant...
