Scientists have learned to more accurately determine the biological age

The epigenetic clock is a widely used biomarker of aging, calculated based on levels of

DNA methylation can be surprisingly unreliable. Scientists have discovered the reason for this and improved their accuracy. Discuss

Scientists have found that technical noise cancause deviations in grades up to 9 years! This, of course, limits the usefulness of the epigenetic clock method. Therefore, the researchers developed a computational solution to improve reliability. Retrained computer versions of six epigenetic clocks have become more accurate - up to 1.5 years.

The researchers noted that the high reliabilityhours is critical for applications in personalized medicine and anti-aging. “The epigenetic clock could first show you to be 50 years old in one test, and then 59 years old in the next.” Now, for most tests, two measurements taken at the same time will differ by less than a year,” the authors of the work explained.
