'Shadow Biosphere' Might be Hiding Strange Life Right Under Our Noses

Faculty member in BCDB, MMG, and PBEE, Dr. David Lynn, points out in a Science article that misfolded proteins--like those implicated in neurodegenerative diseases such as Alzheimer's--show some similarities to life, namely that they can generate diversity in the different ways that they fold, and can undergo chemical evolution, in which those folded proteins are selected not genetically, but chemically. Such precursors could form complex chemical networks, which might be the foundation of radically different life elsewhere in the universe.
