Mitochondrial decay due to oxidant byproducts is a principal underlying contributor to aging, including the degenerative diseases of aging such as brain degeneration. The energy for basic metabolic processes comes from mitochondria, and their decay with age impairs cellular metabolism and leads to cellular decline. Oxidants generated by mitochondria appear to be the major source of the oxidative lesions that accumulate with age. Evidence supports the suggestion that age-associated accumulation of mitochondrial deficits due to oxidative damage is likely to be a major contributor to cellular, tissue, and organismal aging. Can we create artificial mitochondria? This recent article...

‘It's just a really super weird thing,’ says plant geneticist Andrew Leitch If you want to understand the science of longevity and perseverance, you can't do much better than the Welwitschia plant. Considered one of the toughest and longest-living plants, a Welwitschia can survive for thousands of years in the bone-dry deserts of southern Africa. And as long as it's alive, it never stops growing. That's why scientists have studied the DNA of the Welwitschia, in the hopes of unlocking the secrets of its incredible ability to survive for millennia in extremely inhospitable conditions. "It's just a really super weird...
