In a development that has drawn wide attention in biology research, epigenetic clocks estimate biological age from DNA marks. It is the kind of result that blurs the line between a scholarly finding and mainstream news — rigorous in substance, yet consequential enough to matter far beyond the lab.
The finding
They can diverge from a person’s calendar age.
How it works
Researchers use them to test anti-aging interventions.
Why it matters
The clocks track chemical tags on the genome.
What comes next
They are reshaping how aging is studied.
The bottom line
They are reshaping how aging is studied.
The wider view
Researchers caution that findings like this evolve as work is replicated and extended, but the trajectory is clear: biology is moving fast, and epigenetic clocks and the measurement of aging marks a notable step.
