Links for this episode Here is an article on R2A, which is used to cultivate water associated microbes. A solid and clear article describing the "great uncultivated majority."  An article describing the discovery of the archaea. An engaging video summary of the archaea. A recent article suggesting that archaea are the root and originator of eukaryotes like ourselves! An interesting video about the lokiarcheota, which contain the genetic echoes of eukaryotic life. An article about the extremely halophilic archaea. Do extreme halophiles live within salt crystals? The beautiful pink pigment, bacteriorhodopsin, associated with these archaea (despite the "bacterio" portion of the name). The LTEE experiment, describing how researchers can study evolution in the laboratory. Genomic islands in microbiology. The "Archaeal Power Hour" website. A fine video presentation by Dr. Medina-Chavez on archaea. A fine article by Dr. Medina-Chavez and her postdoctoral advisor Dr. Michael Travisano on archaeal communities.
