Immune-activation model mice escape infantile amnesia, retain early memories
Male pups born to mothers treated with immune-stimulating molecules show autism-like behaviors and, unlike wildtype animals, do not lose memories formed during early life.

The true meaning of a null result
This edition of Null and Noteworthy highlights results that reveal the difficulty in drawing definitive conclusions from data, including new findings about epidurals that contradict several others and an apparent null result on sex differences that may derive from “circular logic.”
