Deposition of minerals in caves may be affected by microbes. Geochemical analysis of these minerals can reveal biosignatures of subsurface life on a planet such as the Mars. Research in this area can help NASA build subsurface life probes for future planetary missions.

, a peer-reviewed scientific journal covering research on the origin, evolution, distribution and future of life across the universe, just published a research paper titled "Transport-Induced Spatial Patterns of Sulfur Isotopes (δ34S) as Biosignatures
" by a group of researchers at Pennsylvania State University, the University of Texas at El Paso, and Rice University. The lead author is Dr. Muammar Mansor. The researchers analyzed sample sites in the Frasassi Caves, Italy (Figure 1) and used Energy2D
to simulate the effects of convection and diffusion on the chemical deposition processes (Figure 2). According to the paper, the results of the deposition simulated using Energy2D are consistent with the data collected from the cave sites, suggesting the importance of the effect of natural convection.
This is the second paper that uses Energy2D in astrobiology research (and the 16th published paper that used Energy2D in scientific research to simulate a natural or man-made system). In the first paper
, Energy2D was used to simulate the thermal conditions for the origin of life. Once again, the publication of this paper provides fresh evidence for the broader impacts of our work.
