3Fish That Age Fast Reveal Predictable 'Life Stages' in Aging
Scientists tracked African killifish behavior continuously from adolescence to death. Long-lived fish behaved differently from short-lived ones surprisingly early in life. Machine learning could actually predict how long an individual fish would live based on its young-adult behavior alone. Aging didn't happen as a smooth decline. Instead, fish moved through distinct, stable behavioral stages separated by abrupt transitions.
Vitamin C May Slow Primate Aging by Blocking Iron-Driven Cell Damage
As primates age, iron builds up in tissues and fuels a chain reaction of fat damage in cells. Researchers call this process "ferro-aging" and found that a specific enzyme (ACSL4) drives it. When aged monkeys received vitamin C for over 40 months, it directly blocked that enzyme. The result was reduced tissue damage, better brain and metabolic function, and biological age clocks that ticked backward across multiple organs.
A Newly Found Enzyme Breaks Down NAD+ Inside Mitochondria
Scientists identified a mitochondrial enzyme called SelO that breaks NAD+ into NMN and AMP. This reaction ramps up when mitochondria are working hard, essentially acting as a brake to prevent metabolic overload. It also plays a direct role in fat burning by linking up with fat oxidation enzymes. The mechanism is conserved from bacteria to mammals, suggesting it's been essential for a very long time.
