title: Aging by telomere loss can be reversed.
abstract: Recently in Nature, Jaskelioff et al. (2010) demonstrated that multiple aging phenotypes in a mouse model of accelerated telomere loss can be reversed within 4 weeks of reactivating telomerase. This raises the major question of whether physiological aging, likely caused by a combination of molecular defects, may also be reversible.
