Few singers reach their sunset years with the same voice they had in younger days. Songbirds are no different. New research reveals that elderly swamp sparrows don't sound quite like they used to -- nor do they strike the same fear in other males who may be listening in. Humans are remarkably good at guessing a person's age by their voice. But this is the first time the phenomenon has been demonstrated in wild animals.

Phase 3 drug trial results on improving sleep for persons living with Alzheimer's disease. The US Hispanic/Latino population is predicted to have the largest increase in Alzheimer's and all dementia by mid-century. Artificial intelligence may help with early detection of dementia.

Biomarkers are essential in order to develop clinically-approved interventions for human aging and age-related diseases. We live too long to wait for results to be validated in traditional methods. The stage is now set to develop senescence-based biomarkers of aging. Senescent cells are long-recognized drivers of multiple diseases of aging. The Proteomic Atlas of Senescence-Associated Secretomes, developed at the Buck Institute, is available to the research community to speed translation of therapeutics to clinical use.

Researchers say a gene known to be a biomarker of age plays a key role in age-associated functional and anatomical aging in mouse retinas, a finding that has direct relevance to age-related eye diseases.

In the first randomized controlled trial to evaluate pros and cons of population screening for dementia, Regenstrief Institute and Indiana University School of Medicine researchers found no harm, as measured by patient reported depressive and anxiety symptoms, from screening for Alzheimer's disease and related dementia in diverse rural, suburban and urban primary care clinics.

A new study shows drinking low-fat milk -- both nonfat and 1% milk -- is significantly associated with less aging in adults. Research on 5,834 US adults by Brigham Young University exercise science professor Larry Tucker, Ph.D., found people who drink low-fat (1% and skim) milk experience several years less biological aging than those who drink high-fat (2% and whole) milk.
