  • Nanodiscs catch misfolding proteins red-handed December 15, 2017
    When proteins misfold, accumulate and clump around insulin-producing cells in the pancreas, they kill cells. Now, researchers have obtained a structural snapshot of these proteins when they are most toxic, detailing them down to the atomic level.
  • Offbeat brainwaves during sleep make older adults forget December 15, 2017
    Like swinging a tennis racket during a ball toss to serve an ace, slow and speedy brainwaves during deep sleep must sync up at exactly the right moment to hit the save button on new memories, according to new research.
  • Researchers track muscle stem cell dynamics in response to injury and aging December 14, 2017
    A new study describes the biology behind why muscle stem cells respond differently to aging or injury. The findings have important implications for the normal wear and tear of aging.
  • Lyme bacteria survive 28-day course of antibiotics months after infection December 13, 2017
    Lyme bacteria can survive a 28-day course of antibiotic treatment four months following infection by tick bite, according to a new study using a primate model for the disease. Despite testing negative for Lyme disease, some subjects were infected with Lyme bacteria in heart, brain and other organs.
  • Epigenetic aging linked to bipolar disorder December 12, 2017
    Bipolar disorder may involve accelerated epigenetic aging, which could explain why persons with the disorder are more likely to have -- and die from -- age-related diseases, according to researchers.
  • People say they want to live longer -- if in good health December 11, 2017
    Individually most people only want to live long lives if they will be healthy, according to a new study.
  • Inhibiting TOR boosts regenerative potential of adult tissues December 7, 2017
    Adult stem cells replenish dying cells and regenerate damaged tissues throughout our lifetime. We lose many of those stem cells, along with their regenerative capacity, as we age. Working in flies and mice, researchers discovered that TOR, a nutrient sensing pathway which is central to the aging process, drives the loss of adult stem cells. […]
  • Mutations in neurons accumulate as we age; may explain normal cognitive decline and neurodegeneration December 7, 2017
    Researchers used whole-genome sequencing of individual neurons and found strong evidence that brain mutations accumulate as we age. They also found that mutations accumulate at a higher rate in people with genetic premature aging disorders causing early brain degeneration.
  • Canola oil linked to worsened memory and learning ability in Alzheimer's December 7, 2017
    Canola oil is one of the most widely consumed vegetable oils, yet little is known about its health effects. Now, a study links canola oil consumption in the diet with worsened memory, worsened learning ability and weight gain in mice which model Alzheimer's disease. It's the first study to suggest that canola oil is more […]
  • Number of genetic markers linked to lifespan triples December 7, 2017
    Researchers have studied 389,166 volunteers who gave DNA samples to the UK Biobank, US Health and Retirement Study and the Wisconsin Longitudinal Study. In addition to confirming the eight genetic variants that had already been linked to longevity, this study found 17 more to expand the list of known variants affecting lifespan to 25 genes, […]
