Recent discoveries show that prion phenomena in both humans and yeast are determined by amyloid-like conformations of misfolded proteins, and similar conformations are associated with noninfectious diseases such as Alzheimer's. Shown are AFM images of new amyloid growth from the ends of epitope-labeled seeds encapsulated in diagrams of yeast cells. (See Collins, et al.)
