Fish 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 actua...

This study suggests aging may follow structured, predictable stages rather than a gradual slide.

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 ...

This study suggests vitamin C may help counter age-related iron-driven cell damage in primates.

How Your Immune System Rewires Itself from Birth to Old Age

Researchers mapped immune cells at the single-cell level across the human lifespan, from mid-fetal development through late adulthood. T cells showed the biggest age-related changes. A specific subset...

New Aging Clocks Built From Histone Marks Work Across Species

Researchers built 36 new biological aging clocks using histone modifications (chemical tags on the proteins that package DNA) instead of the usual DNA methylation approach. These clocks worked well ac...

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 metaboli...

This study suggests mitochondrial NAD+ regulation is more complex than previously understood.
