Adaptations Of Endolithic Communities To Abrupt Environmental Changes In A Hyper-arid Desert
The adaptation mechanisms of microbial communities to natural perturbations remain relatively unexplored, particularly in extreme environments. The extremophilic communities of halite (NaCl) nodules from the hyper-arid core of the Atacama […]

Assessing the intrageneric environmental boundaries of the extremophilic cyanobacterium Chroococcidiopsis (Pleurocapsales) and its implications for space exploration
Abstract The cyanobacterium Chroococcidiopsis contains species found in extreme environments, thus providing the opportunity to study adaptation to a range of environments within the confines of a single genus. Due […]

A Centimeter-long Bacterium With DNA Compartmentalized In Membrane-bound Organelles
Cells of most bacterial species are around 2 µm in length, with some of the largest specimens reaching 750 µm. Using fluorescence, x-ray, and electron microscopy in conjunction with genome […]
