APXS Derived Geochemistry of Shallow Water Lens Bodies Within the Mirador Formation, Gale Crater, Mars—Evidence for Intermittent Wet Periods and Implications for the Water Record Open
The Mount Sharp group in Gale crater is typically interpreted to record a progressive change (with increasing elevation) from wetter fluvio‐lacustrine environments to dry, eolian environments. This shift has been linked to orbital evidence…

Dark‐Toned Halite‐Enriched Veins Above the Marker Band Record a Drying Environment in Gale Crater Open
The Martian surface preserves evidence of a global climate transition from wetter to drier conditions, but the nature of the fluids involved in this evolution remains poorly constrained. In Gale crater, the clay‐sulfate transition and pres…

Identification of pathways to high-level vancomycin resistance in Clostridioides difficile that incur high fitness costs in key pathogenicity traits Open
Clostridioides difficile is an important human pathogen, for which there are very limited treatment options, primarily the glycopeptide antibiotic vancomycin. In recent years, vancomycin resistance has emerged as a serious problem in sever…

Ice? Salt? Pressure? Sediment deformation structures as evidence of late-stage shallow groundwater in Gale crater, Mars Open
Persistence of near-surface water during the late evolution of Gale crater, Mars, would have been fundamental for maintaining a habitable environment. Sedimentation in aqueous conditions is evident during the early stages of crater infilli…
