• Circadian rhythms in skin stem cells protect us against UV rays
    Human skin must cope with the sun and other environmental factors that fluctuate in a circadian manner. A study reveals that human skin stem cells deal with these cyclical threats by carrying out different functions depending on the time of day. By activating genes involved in UV protection during the day, these cells protect themselves against radiation-induced DNA damage. The findings could pave the way for new strategies to prevent premature aging and skin cancer.
  • Molecule produced during exercise boosts brain health
    Research has shown that exercise is good for the brain. Now investigators have identified a molecule called irisin that is produced in the brain during endurance exercise and has neuroprotective effects. Researchers were able to artificially increase the levels of irisin in the blood to activate genes involved in learning and memory. The findings may be useful for designing drugs that utilize this exercise-induced molecule to guard against neurodegenerative diseases and improve cognition.
  • 'Peanut butter' test can help diagnose Alzheimer's disease, researchers find
    A dollop of peanut butter and a ruler can be used to confirm a diagnosis of early stage Alzheimer’s disease, researchers have found.
  • Osteoporosis a major threat to women's future independence
    A new report shows that women may expect to live longer, but their quality of life will be seriously jeopardized if action to protect their bone health is not taken. The report provides solutions for fracture prevention and osteoporosis management.
  • High-dose radiation therapy for bladder cancer has comparable tumor control compared to surgery
    Standard and reduced high-dose volume radiation therapy for muscle-invasive bladder cancer provide comparable tumor control and decreased late toxicity when compared to surgery.
  • Cataract surgeries on the rise as boomers age, raising access, cost issues
    A study focused on cataract surgery has found that more people are getting the vision-improving procedure, seeking it at younger ages and having both eyes repaired within a few months, rather than only treating one eye.
  • Tool to improve seniors' autonomy, promote active aging
    Researchers have developed an ICT tool in prototype phase that will help seniors to monitor their health and the security of their home, and avoid social exclusion by means of digital technologies. The final aim of the project is to improve seniors’ quality of life and boost their autonomy.
  • Loss of anti-aging gene possible culprit in age-related macular degeneration
    The loss of an anti-aging gene induces retinal degeneration in mice and might contribute to age-related macular degeneration, the major cause of blindness in the elderly. Researchers say that in their animal studies, loss of expression of the aging-suppressor gene Klotho leads to characteristics observed in wet and dry macular degeneration seen in humans. Researchers say gene therapy or cell therapy might be able to induce new expression of Klotho in the aging retina.
