  "textContent": "\n\nOld mice got smarter when researchers tweaked their gut bacteria and stimulated the vagus nerve — restoring cognitive performance to young-animal levels, according to Stanford Medicine.\n\nThe study, published in _Nature_ , traced the mechanism in detail. A bacterium called _Parabacteroides goldsteinii_ proliferates as mice age and triggers the release of medium-chain fatty acids that set off an inflammatory immune response in gut myeloid cells. — Read the rest \n\nThe post Stanford study links gut bacteria to age-related memory loss appeared first on Boing Boing.",
