SENIOR VOLUNTEERS WARD OFF BRAIN ‘SHRINKAGE’

The memory center in the brains of seniors who volunteered in public schools for two years maintained their size, rather than shrinking as part of the normal aging process, report researchers. The findings suggest that retirees who take part in meaningful social activity can prevent shrinkage in their brains’ memory centers and avert age-related cognitive problems. In men, the researchers found, the …

Even at a molecular level, taking it slow helps us cope with stress

Scientists at the University of California, Berkeley, have identified a new molecular pathway critical to aging, and confirmed that the process can be manipulated to help make old blood like new again. The researchers found that blood stem cells’ ability to repair damage caused by inappropriate protein folding in the mitochondria, a cell’s energy station, is critical to their survival …

How Root Canals Could Spark Autoimmune Diseases

Are root canals safe? Dr. George Meinig, author of Root Canal Cover-Up, was a founding member of the American Association of Endodontics. He quit the association later in his career after he saw firsthand the adverse affects that root canals have on the immune system. Dr. Meinig also witnessed the irreparable damage to the jaw bone caused by the infected cavitation sites …
