Loud noise can damage the inner ear and cause hearing loss. Studying mice, researchers at Washington University School of Medicine in St. Louis and the University of Iowa have shown that a drug compound can block damage caused by loud noise, raising the possibility of medication that prevents noise-induced hearing […]

Dementia is one of the most debilitating consequences of Parkinson’s disease, a progressive neurological condition characterized by tremors, stiffness, slow movement and impaired balance. Eighty percent of people with Parkinson’s develop dementia within 20 years of the diagnosis, and patients who carry a particular variant of the gene APOE are at especially […]

Clumps of proteins inside cells are a common thread in many neurodegenerative diseases, including amyotrophic lateral sclerosis (ALS) or Lou Gehrig’s disease. These clumps, or solid aggregates of proteins, appear to be the result of an abnormality in the process known as liquid-liquid phase separation (LLPS), in which individual proteins […]

From avoiding lower back pain to burning more calories and improving memory, weightlifting offers wide-ranging benefits for body and mind, say U of A experts. While research shows little or no link between exercise and any meaningful long-term weight loss, that doesn’t mean exercising, particularly resistance training, doesn’t provide a […]

Biologists identify hearing-loss receptor in mice, use drug to prevent hearing damage. Once you start to lose your hearing, you can’t get it back. But what if you could prevent hearing loss by blocking in advance the effects of loud noises? That’s a route a team of biologists at the University […]

Survival may more than double for adults with glioblastoma, the most common and deadly type of brain tumor, if neurosurgeons remove the surrounding tissue as aggressively as they remove the cancerous core of the tumor. This discovery, reported in a retrospective study headed by researchers at UC San Francisco, is […]

Chronic inflammation, which results when old age, stress or environmental toxins keep the body’s immune system in overdrive, can contribute to a variety of devastating diseases, from Alzheimer’s and Parkinson’s to diabetes and cancer. Now, scientists at the University of California, Berkeley, have identified a molecular “switch” that controls the […]

The phrase “Pavlov’s dogs” has long evoked images of bells, food and salivating dogs. Even though this tried-and-true model of repetitive patterns mimics a variety of learning processes, what happens on a cellular level in the brain isn’t clear. Researchers at the University of New Hampshire took a closer look […]

Scientists suggest a new strategy that uses induced pluripotent stem cells (iPSCs) to regulate immune reaction to transplanted tissues.
