The travertine deposits could provide a prospective geomicrobiological snapshot of the early
Earth considering its similarity with ancient stromatolites. Herein, we investigated the …

Modern travertines, carbonate deposits in Ca-rich hydrothermal water with high pCO 2, often
display a changing environment along the water path, with corresponding variability in the …

Balneotherapy is an ancient practice which remains commonplace throughout the world due
to perceived health benefits that include relief of arthritis, fibromyalgia and relaxation …

Carbonate rocks retain a well preserved record of biologically associated structures at the
outcrop to millimeter scale, however microscale features such as cellular fossils are rarely …

Stable δ13C isotope analysis at hot and cold springs suggests that rapid degassing
overprints carbon isotopic biosignatures even when microbial activity produces biogenic …

Microbially induced carbonate precipitation (MICP) is a natural process with potential
biotechnological applications to address both carbon sequestration and sustainable …

Researchers at the Center for Frontiers of Subsurface Energy Security (CFSES) have

The Asian monsoon is one of the largest climatic systems in the world, but age of its onset
has been estimated differently ranging from the late Eocene to the Quaternary. We …

This study investigated the Utah Crystal Geyser, a unique low-temperature, CO2-rich geyser
relevant to Mars, icy moons, and asteroids. Samples from the site had a range of textural and …
