Explore the fundamental biological mechanisms behind aging in this 13-minute educational video that examines why organisms age, whether the aging process can be halted, and how cells respond to aging at the molecular level. Discover the cellular and molecular processes that drive aging, including DNA damage accumulation, telomere shortening, mitochondrial dysfunction, and cellular senescence. Learn about the various theories of aging, from the free radical theory to programmed aging hypotheses, and understand how different biological systems contribute to the aging process. Examine current research on anti-aging interventions and life extension strategies, including caloric restriction, genetic modifications, and pharmaceutical approaches. Investigate how cells detect and respond to aging signals through various pathways and mechanisms, and understand the role of oxidative stress, inflammation, and metabolic changes in cellular aging. Gain insights into the evolutionary perspectives on aging and why aging exists as a biological phenomenon across different species.
