Electroactive microorganisms (EAMs) are ubiquitous in nature and have attracted
considerable attention as they can be used for energy recovery and environmental …

The recent recovery of genomes for organisms from phyla with no isolated representative
(candidate phyla) via cultivation-independent genomics enabled delineation of major new …

In the ongoing debates about eukaryogenesis—the series of evolutionary events leading to
the emergence of the eukaryotic cell from prokaryotic ancestors—members of the Asgard …

Asgard is a recently discovered superphylum of archaea that appears to include the closest
archaeal relatives of eukaryotes,,,–. Debate continues as to whether the archaeal ancestor …

Challenges in cultivating microorganisms have limited the phylogenetic diversity of currently
available microbial genomes. This is being addressed by advances in sequencing …

The origin and cellular complexity of eukaryotes represent a major enigma in biology.
Current data support scenarios in which an archaeal host cell and an alphaproteobacterial …

Microalgae have emerged as a renewable and sustainable candidate for bioenergy
production coupled with pollutant removal from wastewater. However, costly biomass …

The tree of life is one of the most important organizing principles in biology 1. Gene surveys
suggest the existence of an enormous number of branches 2, but even an approximation of …

Woese and Fox's 1977 paper on the discovery of the Archaea triggered a revolution in the
field of evolutionary biology by showing that life was divided into not only prokaryotes and …

The concept of a last universal common ancestor of all cells (LUCA, or the progenote) is
central to the study of early evolution and life's origin, yet information about how and where …
