James Tour appears in the source digest through a video lecture, "Chiral-induced Spin Selectivity // A Course on Abiogenesis by Dr. James Tour." In the episode he analyzes a claim of molecular homochiral evolution, asking how proteins could become homochiral when no prebiotically relevant route has been shown to synthesize, separate or polymerize homochiral amino acids. He also discusses the possibility of racemic molecules in cells, and introduces Chirality-Induced Spin Selectivity (CISS) (CISS), presenting it as enabling the cell to be an efficient machine.
Status of the material
This is a position/argument about abiogenesis and the origin of biological homochirality, not experimental evidence about CISS itself. The digest presents it as a linked lecture rather than as a research result, and it should be attributed accordingly. The source does not state any institutional affiliation for Tour.
