- The Kardashians took a commercially available blood test on the season 5 finale of The Kardashians and were reported to be ageing slower than peers, with Khloé (39) showing a biological age of 28.
- Vadim Gladyshev and colleagues at Harvard Medical School introduced a new molecular clock that estimates biological age and predicts a “time to death” using gene‑activity patterns from over 4,000 people and animal data.
- The Horvath clock, the most cited epigenetic aging clock, is contrasted with Gladyshev’s method, which the researchers claim is more sensitive than earlier clocks.
- The new test is currently limited to research use, providing statistical probability estimates rather than precise death dates, and could accelerate anti‑ageing drug trials and inform age‑related policy.
- Becca Levy’s Yale research found that individuals with negative views of aging die about 7.5 years earlier than those with positive beliefs, suggesting psychological factors can affect biological aging.
Why it matters: Researchers gain a faster, more sensitive metric that could slash years from anti‑ageing drug trials and reshape age‑based regulations, while individuals may confront unsettling probabilistic death estimates that could alter health habits and mental wellbeing and influence public perception of aging.
