Testing Microbial Biomining From Asteroidal Material Onboard The International Space Station

by Keith CowingJanuary 22, 2024February 14, 2026

Expanding human space exploration beyond Earth’s orbit necessitates efficient technologies for self-sustainable acquisition of local resources to overcome unviable resupply missions from Earth. Potential source of materials are asteroids, some […]

Representative Raman and nanoSIMS data collected in this study Across all panels data from two representative cells, “1” and “2”, are noted. Representative nanoSIMS isotopic images of are shown in Panel A, with pixel counts labeled on the x and y axes. From left to right, the pixel intensity in each panel corresponds to direct ion counts for 1 H- , 2 H- , and the fractional abundance of deuterium (2 F), respectively. The top row shows cells grown in 0% 2 H2O (natural abundance); the bottom row displays cells grown in 50 at. % 2 H2O. Representative single-cell fitted Raman spectra are shown in Panel B, with the characteristic C-H band between 2800 and 3000 cm-1 clearly visible. For cells grown in deuterated media (Cell 2), the C-D band emerges between 2040 and 2300 cm-1. Panel C displays a typical micrograph captured through a confocal Raman microspectroscope. The scale bar represents 2µm. Cells in all panels represent T. hydrogeniphilus. The yellow boxes in the top-left facet of Panel A, and Panel C, represent a correlated region imaged with nanoSIMS and Raman (reflected light), respectively. -- biorxiv.org

Tricorder Tech: Quantitative Measurement Of Microbial Growth Rate With Raman Microspectroscopy

by Keith CowingDecember 28, 2023December 28, 2023

Rates of microbial activity and growth are fundamental to understanding environmental geochemistry and ecology.

Random interactions reproduce the aggregate diversity observed in simple interaction maps. For each value of affinity and asymmetry, we show a randomly drawn interaction map (bottom left matrix, with the color scale of Fig. 3), a snapshot of the result of the simulated annealing, and the aggregate category, as in Fig. 2. Here and in the following, the lattice has 30 × 30 sites, and there are 100 particles. -- physics.bio-ph

a Overall structure of E.coli RNA polymerase EC. αI, αII, β′, β and ω subunit of RNAP were colored in green, cyan, gray, yellow, and red, respectively. RNA, template strand DNA (TS), non-template strand DNA (NTS) are shown in red, blue and dark green, respectively. b Model and map of three unnatural base pairs; dB:STP, dB:UTP and dS:BTP are shown with Cryo-EM density maps. c Active site of three UBP EC structures. Bridge helix (BH) is colored in green. UBP in +1 position were colored yellow. Other parts of the structures are colored white. The nitrogen, oxygen, phosphate, and carbon atoms of the base pair at i + 1 position are colored in blue, red, orange, and yellow, respectively. -- Nature Communications
