Mitochondrial DNA Shortfalls May Fuel Inflammation as We Age
New Clues on Inflammation and Aging: Mitochondrial DNA’s Role Scientists are uncovering a surprising link between the tiny powerhouses inside our cells and the chronic inflammation often seen as we grow older. A study led by researchers at the Max Planck Institute for Biology of Ageing in Germany suggests that when mitochondria struggle to replicate…

How Mitochondrial ‘Rubbish DNA’ May Drive Age-Related Inflammation—and What It Means for Healthy Aging
Understanding the Mitochondrial Mess Behind Aging As people live longer, researchers are increasingly focused on the tiny powerhouses inside our cells: the mitochondria. A new line of investigation suggests that a surprising source of chronic inflammation in aging may lie within the mitochondria themselves. When these organelles mismanage their own DNA, they can release material…

Second Round of Exercise Boosts Muscle Growth in Mice, Study Finds
Overview: A Surprising Twist in Muscle Memory A new study from the University of Illinois Urbana-Champaign suggests that a second round of exercise after a short break can trigger greater muscle growth than a first round. In mice that freely ran on an exercise wheel for four weeks, paused for four weeks, and then ran…

Second round of exercise boosts muscle growth in mice
New study shows a second exercise bout can boost muscle growth in mice A new study published in the American Journal of Physiology: Cell Physiology reports that mice who voluntarily ran on an exercise wheel for four weeks, paused for four weeks, and then ran again for another four weeks gained more muscle than those…

Muscle memory in action: a second exercise round boosts mouse growth
Muscle memory in action: a second exercise round boosts muscle growth A new study in mice suggests that a second bout of voluntary wheel running, after a four-week pause, can provoke greater muscle growth than the initial training. The research, published in the American Journal of Physiology: Cell Physiology, found that the second round led…
