A Potential New Way to Prevent Noise-Induced Hearing Loss: Trapping Excess Zinc

Hearing loss is a pervasive problem, affecting one in eight people aged 12 and up in the U.S. While hearing loss has multiple causes, an important one for millions of people is exposure to loud noises, which can lead to gradual hearing loss, or people can lose their hearing all at once. The only methods used to prevent noise-induced hearing loss today are avoiding loud noises altogether or wearing earplugs or other protective devices during loud activities. But findings from an intriguing new NIH-supported study exploring the underlying causes of this form of hearing loss suggest it may be possible to protect hearing in a different way: with treatments targeting excess and damaging levels of zinc in the inner ear.

Unraveling the Complexity of Cellular Identity in Health and Disease

Better understanding a cell’s identity and function—its “phenotype”—is fundamental to many medical discoveries. Fortunately, new technology has made a deeper understanding of cellular phenotypes more accessible than ever. Learn how NLM experts and others are working to accelerate this field in a new blog from NLM Scientific Director Dr. Richard H. Scheuermann.
