TL;DR: It is demonstrated that total prokaryotic community structure can be directly correlated to geochemistry within these sediments, thus enhancing the understanding of biogeochemical cycling and the ability to predict metabolisms of uncultured microbes in deep-sea sediments.

TL;DR: Information from the first available genomes of AOA indicate that their metabolism is fundamentally different from that of their bacterial counterparts, involving a highly copper-dependent system for ammonia oxidation and electron transport, as well as a novel carbon fixation pathway that has recently been discovered in hyperthermophilic archaea.

TL;DR: The results suggest that archaea may contribute to N2O production in terrestrial ecosystems, however, they are not capable of nitrifier-denitrification and thus do not produce increasing amounts of the greenhouse gas when oxygen becomes limiting.

TL;DR: It is reported that dextran sodium sulfate (DSS)-induced colitis is accompanied by major shifts in the composition and function of the intestinal microbiota of STAT1−/− and wild-type mice, as determined by 454 pyrosequencing of bacterial 16S rRNA (gene) amplicons, metatranscriptomics and quantitative fluorescence in situ hybridization of selected phylotypes.

TL;DR: Samples of acidic springs, water and mud holes of 14 major solfataric fields of Iceland are sampled in order to isolate both heterotrophic and autotrophic members of the order Sulfolobales and to find affiliated genetic elements e.g. plasmids and viruses.
