The first site (1) is a recent article from Nature that reports a newly discovered group of tiny microbes, Nanoarchaeota, that has "one of the smallest genomes known." The next Web site (2), from the University of Texas, gives a brief overview of nanobacteria, discusses the controversy over whether the small size can support independent life, and includes an image gallery. An article from Natural Science (3) details the controversy further based on two laboratory studies attempting to isolate nanobacteria and characterize its RNA. The next article (4), offered by Emory University, discusses the new field of nanobiology, and work that the University is doing to advance the field, including hosting the first ever International Conference on Nanobiology (5). The proceedings of a National Research Council workshop on the Size Limits of Very Small Microorganisms (6) is an in-depth look at the question of how small a free-living organism can actually be. Next (7) is an article that considers the possibility that nanobacteria are partially responsible for developing kidney stones. The last resource (8) focuses on the convergence of biotechnology and nanotechnology, purporting the field to be the "next great revolution in medicine."
