Avoidance of rejuvenation: a stress test for evolutionary theories of aging
The biological feasibility of human rejuvenation remains a subject of intense debate, yet answering this question is critical for guiding research strategies. Should aging research focus only on reversing aging in older individuals, or pausing its progression at mid-ages, be more accessible? Here, we attempt to address this question with evolutionary biology. Rejuvenation occurs in a few species, and, paradoxically, is typically induced by stress but not used under optimal conditions. Using...
Thymic health consequences in adults
The thymus is essential for establishing T cell diversity early in life, but undergoes profound involution with age and has therefore traditionally been regarded as largely nonfunctional in adults^(1,2). Here we propose that preserving thymic functionality is integral to adult health and longevity. We developed a deep learning framework to quantify thymic health from routine radiographic images and evaluated its association with longevity and risk of major age-associated diseases in two large...
