Good Mitochondrial Research
Something a little more scientific today from the Journal of Physiology, but a good sign: "The mitochondrial theory of ageing proposes that the accumulation of oxidative damage to mitochondria leads to mitochondrial dysfunction and tissue degeneration with age. However, no consensus has emerged regarding the effects of ageing on mitochondrial function, particularly for mitochondrial coupling (P/O). One of the main barriers to a better understanding of the effects of ageing on coupling has been the lack of in vivo approaches to measure P/O." The researchers go on to show a way of accomplishing this task - which means groups working on ways to repair age-damage mitochondria will have an objective measure of how successful they are.
