More than one million stem cell treatments have been conducted in the United States during the past ten years. Physicians and other healthcare providers are beginning to realize regenerative medicine is the future of medicine; however major health issues remain unanswered. Dr. Nathan Bryan, one the country’s leading experts in the mechanism of nitric oxide, will tell more than seven thousand physicians attending the 27th Annual Spring Conference of the American Academy of Anti-Aging Medicine on Saturday that “the ability to use our own cells to heal our own body make good medical sense.
Many Americans in their 50s and early 60s are worried about declining brain health, especially if they have loved ones with memory loss and dementia, a new national poll finds. But while the majority of those polled say they take supplements or do puzzles in an effort to stave off brain decline, very few of them have talked with their doctors about evidence-based ways to prevent memory loss. So they may miss out on proven strategies to keep their brains sharp into their later years.
Can science measure what it means to be wise? A growing body of evidence suggests that wisdom is a complex concept that contributes to mental health and happiness, according to a review in the May/June issue of Harvard Review of Psychiatry.

University of Maryland researchers analyzed an evolutionary tree reconstructed from the DNA of a majority of known bat species and found four bat lineages that exhibit extreme longevity. They also identified, for the first time, two life history features that predict extended life spans in bats.
For decades, articles in research journals and the popular press alike have reported that being a family caregiver takes a toll on a person’s health, boosting levels of inflammation and weakening the function of the immune system. Now, after analyzing 30 papers on the levels of immune and inflammatory molecules in caregivers, Johns Hopkins researchers say the link has been overstated and the association is extremely small. Caregiver stress explains less than 1 percent of the variability in immune and inflammation biomarkers, they report. Their new meta-analysis was published March 10 in The Gerontologist.
