Memory (1 of 2) (IMAGE) Rice University Caption Actin pulls upon and stabilizes soluble cytoplasmic polyadenylation element binding proteins into longer, insoluble prion-like fibers, a process believed to be key to stabilizing long-term memories. Rice University researchers simulated the force (F) applied by actin through computer models that predict how proteins are likely to find their least-energetic (and most stable) states.
