Industry regulation and individual consumer choice can reduce exposure to such chemicals, […]

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. The team, led by Professor Ken-ichiro Seino of Hokkaido University’s Institute for Genetic Medicine, found that thymic epithelium cells derived from mouse induced pluripotent stem cells (iPSCs) can regulate immune response […]

Cancer’s genetic causes are more diverse than previous scientific studies have indicated – a conclusion reached by researchers from ETH Zurich and University Hospital Zurich. Through their participation in an international research collaboration, they helped compile the most comprehensive catalogue to date of gene alterations associated with cancer. Their work […]

A new study finds that one side effect of lupus could also make patients with the autoimmune condition more vulnerable to a skin infection, or spreading the infection to others. In the paper, published in the Journal of Investigative Dermatology, researchers found that 50% of skin rashes in patients with lupus contained an […]

A merger of math and medicine may help to improve the efficacy of immunotherapies, potentially life-saving treatments that enhance the ability of the patient’s own immune system to attack cancerous tumors. By creating mathematical models that represent the complex interactions within the tumor microenvironment (TME), the nonmutated cells, connective tissues […]

Using sophisticated algorithms to explore regions of the genome whose roles in cancer have been largely uncharted, an international team of researchers has opened the door to a new understanding of the disease’s genetic origins.
