Crustal mineralogy drives microbe diversity abundance beneath Earth s surface

Crustal mineralogy drives microbe diversity beneath Earth s surface By (0) Researchers pictured from left to right, Lily Momper, Brittany Kruger and Caitlin Casar  pose next to a borehole in an abandoned mine in South Dakota where they cultivated microbial biofilms. Photo by Matt Kapust April 8 (UPI) Deep beneath the surface of the earth, microbes proliferate without sunlight and oxygen eating and breathing minerals, these microbes colonize the rocks that buoy the planet s continents. For obvious reason, scientists don t know a lot about these microbes, but researchers estimate they account for anywhere between 20 and 80 percent of Earth s bacterial and archaeal biomass.

Earth s crust mineralogy drives hotspots for intraterrestrial life

The continental deep subsurface is likely one of the largest reservoirs of bacteria and archaea on Earth, many forming biofilms - like a microbial coating of the rock surface. This microbial population survives without light or oxygen and with minimal organic carbon sources, and can get energy by eating or respiring minerals. Distributed throughout the deep subsurface, these biofilms could represent 20-80% of the total bacterial and archaeal biomass in the continental subsurface according to the most recent estimate. But are these microbial populations spread evenly on rock surfaces, or do they prefer to colonize specific minerals in the rocks?

South Dakota s DUNE Project — Kiewit-Alberici Preps Former Goldmine for Science Experiment : CEG

(Sanford Underground Research Facility photo) International science came to the Black Hills of western South Dakota, because that s where the deep hole is. Over the last century, the hole Ross Shaft was sunk 5,000 ft. to give access to lateral tunnels from which gold was extracted from sedimentary rock to a depth of 8,000 ft. Now the opening into the earth is being repurposed into an entranceway for a highly-sophisticated underground physics experiment. Most of us non-scientists have to wrestle a bit to comprehend the scientific aspect of the project, which is called the

Fermilab names Kevin Pitts as chief research officer | US Department of Energy Science News

DOE/Fermi National Accelerator Laboratory Kevin Pitts of the University of Illinois has been named chief research officer at Fermilab National Accelerator Laboratory beginning March 1. His focus will be on oversight for the international Deep Underground Neutrino Experiment, including advancing scientific excellence across the laboratory through strong communication, collaboration and coordination with the Department of Energy and other partners. He joins the laboratory as it prepares to usher in a new era of science and innovation in particle physics research and discovery. We are proud to have Kevin Pitts join Fermilab at a time when DUNE is underway, said Joe Lykken, deputy director for research at Fermilab. His leadership and research collaboration with Fermilab make him the ideal person to direct the development of the DUNE research program both at the laboratory and with our partner institutions.
