Every cell contains a tiny clock called a telomere, which shortens each time the cell divides. Short telomeres are linked to a range of human diseases, including HIV, osteoporosis, heart disease and ageing. Previous studies show that an enzyme within the cell, called telomerase, keeps immune cells young by preserving their telomere length and ability to continue dividing…
Older adults can decrease their risk of disability and increase their likelihood of maintaining independence by 41 percent by participating in a walking exercise program, according to a new University of Georgia study…
