  • Could olfactory loss point to Alzheimer's disease? August 16, 2017
    Simple odor identification tests may help track the progression of Alzheimer's disease before symptoms actually appear, particularly among those at risk.
  • Eating habits affect skin's protection against sun August 15, 2017
    Sunbathers may want to avoid midnight snacks before catching some rays, new research recommends. A study in mice shows that eating at abnormal times disrupts the biological clock of the skin, including the daytime potency of an enzyme that protects against the sun's harmful ultraviolet radiation.
  • Long-term testosterone therapy improves urinary, sexual function and quality of life August 15, 2017
    A new study shows a significant improvement in both sexual and urinary function as well as quality of life for hypogonadal men who undergo long-term testosterone replacement therapy.
  • New machine learning program shows promise for early alzheimer's diagnosis August 15, 2017
    A new machine learning program appears to outperform other methods for diagnosing Alzheimer's disease before symptoms begin to interfere with every day living, initial testing shows. Early diagnosis and treatment -- the goal of the new computer based program -- is key to allowing those with the disease to remain independent longer.
  • Artificial blood vessels mimic rare accelerated aging disease August 15, 2017
    Biomedical engineers have grown miniature human blood vessels using stem cells taken from patients with an extremely rare genetic disease called progeria that causes symptoms resembling accelerated aging in children. The blood vessels exhibit many of the symptoms and drug reactions associated with progeria and will help doctors and researchers screen potential therapeutics for the […]
  • Granulins are brain treasure, not trash August 14, 2017
    Using new tools, researchers can see granulins inside cells within lysosomes, and propose that granulins have important jobs in the lysosome that are necessary to maintain brain health, suppress neuroinflammation, and prevent neurodegeneration.
  • Running rats remember better August 14, 2017
    Young rats with access to a running wheel show improved memory later in life and increased activity of neurons generated in adulthood, finds a new study. The results raise the possibility that exercise early in life may help to protect against age-related cognitive decline.
  • Cardiac stem cells from young hearts could rejuvenate old hearts August 14, 2017
    Cardiac stem cell infusions could someday help reverse the aging process in the human heart, making older ones behave younger, according to a new study.
  • Brain scan study adds to evidence that lower brain serotonin levels are linked to dementia August 14, 2017
    In a study looking at brain scans of people with mild loss of thought and memory ability, researchers report evidence of lower levels of the serotonin transporter -- a natural brain chemical that regulates mood, sleep and appetite.
  • Menopausal status may better predict blood vessel health in women than fitness level August 12, 2017
    High physical fitness is known to be related to enhanced blood vessel dilation and blood flow (endothelial function) in aging men. However, for women, endothelial function and the effect of exercise may be related more to menopausal status than fitness.
