Nanobacteria: not a life form?


This Natural Science article examines the issue of whether or not nanobacteria should be considered living organisms. Finnish scientists have reported a partial characterization of nanobacterial ribosomal RNA, thereby providing evidence that nanobacteria are actual life forms. However, other studies have shown that previous structures thought to be nanobacteria cells and "dwellings" can be recreated as inanimate structures using the culturing media used for nanobacterial cultures. The article features links to related articles.
