io9 included Nick Fury on their list of 10 Superheroes That You Didn't Know Had Superpowers. Their little blurb doesn't attribute his comparatively youthful appearance to anything in particular. Would a nod to the Infinity Serum have killed them?
EDIT: Hmm, looks like they've since revised their article. I still think it's silly, though.
CBR.com has posted preview pages for Howard Chaykin's upcoming Avengers 1959 #1. Looking good, man.
Because what's the world without rumors, a new teaser image suggests that Matt Fraction will be writing Fury as a member of the Defenders.
