African killifish could hold secrets to reversing muscle ageing

As we age, our muscles start to waste. Called sarcopenia, it happens to us all, yet no one has ever understood why and how it happens. Now new research from the Australian Regenerative Medicine Institute (ARMI) at Monash University has used a surprising animal model—the African killifish—to reveal that towards the end of life, our muscles actually reverse to an "early-life" state, slowing mortality. This finding may provide a clue to slowing, halting or even reversing age-related loss of muscle mass and strength.
