Low-temperature physics: A chilling effect for molecules

this process directly to sulphate reduction (Fig. 1d). In doing so, the archaea produce an unexpected metabolic end product — zero-valent sulphur (S) — which is released from the archaea, probably in the form of disulphide (HS2). This finding also led the authors to the revelation that the Deltaproteobacteria present in the Isis-sediment culture seem not to… (More)
