Scientists from Duke, Harvard, and the University of Otago have unveiled a game-changing tool called DunedinPACNI. It uses a single AI brain scan to reveal how fast a person is biologically aging.

The results are published in the journal Nature Aging. From a single MRI brain scan, the tool can estimate your risk in midlife for chronic diseases that typically emerge decades later.

"It seems to be capturing something that is reflected in all brains." The researchers looked at how brain structure matched biological age. (Whitman et al., Nat. Aging, 2025) ...
