Nanosized, hyperthermophilic Archaeon discovered under the sea off Iceland
John Whitfield reports on the discovery of a new phylum of Archaea, the third domain of life. The organism Nanoarchaeum equitans was obtained from a submarine hot vent where it grows attached to the surface of another Archaeon, a previously unknown member of the genus Ignicoccus. For further details see:

Nanobacteria: not a life-form?
John Cisar and colleagues present evidence suggesting that "nanobacteria," which are associated with kidney stones and other products of biomineralization, are initiated by nonliving macromolecules and are reproduced by self-propagating microcrystalline apatite

Novel nano-organisms from Australian sandstones
Philippa Uwins and others at the University of Queensland report in the American Mineralogist on the discovery of reproductive cellular structures similar in morphology to Actinomycetes and fungi, but only one-tenth the diameter (20 nm to 1.0 micrometer). Obtained from Jurassic and Triassic sandstones from offshore petroleum exploration wells, the structures are referred to by their discoverers as "nanobes," rather than nanobacteria, as their phylogeny has yet to be determined. The full text of the article in pdf format is available from the Microscopy-UK Web site. Links to other articles about nano-organisms are included in Dr. Uwins' Web page

Nannobacteria: Surely Not Figments, But What Under Heaven Are They
According to Robert L. Folk, nannobacteria are very small living creatures in the 0.05 to 0.2 micrometer range. In this review by their discoverer, it is conjectured that nannobacteria run most of the earth’s surface chemistry and form most of the world’s biomass. Nevertheless, they remain "biota incognita" to the biological world as their genetic relationships, metabolism and other characteristics remain to be investigated Search, Today
