  • High vinculin levels help keep aging fruit fly hearts young July 17, 2018
    A new discovery in how heart muscles maintain their shape in fruit flies sheds light on the crucial relationship between cardiac function, metabolism, and longevity. Researchers have discovered that maintaining high levels of the protein vinculin confers health benefits to fruit flies. Their work shows that fruit flies bred to produce 50 percent more vinculin […]
  • While men lose more weight on low-carb diets, women show improved artery flexibility July 17, 2018
    According to the Centers for Disease Control and Prevention, an estimated 1 out of 3 American adults live with higher than normal blood sugar levels known as prediabetes. Researchers recently found that while men may lose more weight on low-carb diets, women actually see better improvements in artery flexibility. It's a finding that may help […]
  • Majority of older adults with probable dementia are likely unaware they have it, study suggests July 17, 2018
    An analysis of information gathered for an ongoing and federally sponsored study of aging and disability adds to evidence that a substantial majority of older adults with probable dementia in the United States have never been professionally diagnosed or are unaware they have been.
  • Test for Alzheimer's disease directly measures synaptic loss July 16, 2018
    Researchers have tested a new method for directly measuring synaptic loss in individuals with Alzheimer's disease. The method, which uses PET imaging technology to scan for a specific protein in the brain linked to synapses, has the potential to accelerate research for new Alzheimer's treatments, the researchers said.
  • New development in 3D super-resolution imaging gives insight on Alzheimer's disease July 16, 2018
    One major problem with understanding Alzheimer's is not being able to clearly see why the disease starts. A super-resolution 'nanoscope' now provides a 3D view of brain molecules with 10 times greater detail. This imaging technique could help reveal how the disease progresses and where new treatments could intervene.
  • Implications of unmet promise of a miracle drug for Alzheimer's disease July 16, 2018
    Authors lament the unmet promise of a miracle drug for Alzheimer disease but are heartened by what they see as encouraging improvements in care (care transformation) for a growing population of older adults, many with dementia.
  • Protecting ribosome genes to prevent aging July 16, 2018
    Aging is a process of gradual deterioration from exposure to time and the elements; this process begins with deterioration deep inside every cell. Researchers have identified a protein that guards cells against senescence -- aging-related problems -- by protecting a particularly vulnerable set of genes.
  • A constellation of symptoms presages first definitive signs of multiple sclerosis July 16, 2018
    Researchers document the health problems that precede a diagnosis of multiple sclerosis.
  • Antioxidant benefits of sleep July 12, 2018
    Scientists found that short-sleeping fruit fly mutants shared the common defect of sensitivity to acute oxidative stress, and thus that sleep supports antioxidant processes.
  • Gene controls bone-to-fat ratio in bone marrow July 12, 2018
    In an unexpected discovery, researchers have found that a gene previously known to control human metabolism also controls the equilibrium of bone and fat in bone marrow as well as how an adult stem cell expresses its final cell type. The findings could lead to a better understanding of the disruption of bone-to-fat ratio in […]
