Discovering six new vitamins in a single metabolic pathway is unprecedented, but then, neither methanogenesis nor Ralph Wolfe is standard. The metabolic pathway for converting CO2 to CH2, which is unique to the methanogenic archaebacteria, has shown that there is novel microbiology and metabolic biochemistry work yet to do.

Biological light emission and biological clocks both in a single short review! The marine alga Gonyaulax emits light in the dark. Its light/dark clock keeps running for weeks in dim light. The physical location of the clock is unclear, but new work indicates that control functions at the level of translation into proteins, and not at gene transcription.
