In a potentially fundamental advance, researchers have opened up a novel approach to combating the effects of aging with the discovery that a special category of cells, known as senescent cells, are bad actors that promote the aging of the tissues. Cleansing the body of the cells, they hope, could postpone many of the diseases of aging.
The findings raise the prospect that any therapy that rids the body of senescent cells would protect it from the ravages of aging. But many more tests will be needed before scientists know if drugs can be developed to help people live longer.
