Laboratory Experiments Identify Meteoritic Organic Precursors for Chlorinated Compounds Detected by the Sample Analysis at Mars (SAM) Instrument at Gale Crater

Journal of Geophysical Research: Planets, Volume 131, Issue 11, November 2026.
Abstract The Viking missions landed two spacecraft on Mars each equipped with a pyrolysis‐gas chromatograph‐mass spectrometer system capable of detecting signs of life. Although working as intended, detections of chloromethane and dichloromethane were initially attributed to terrestrial contamination.

Sulfidation Reaction Mechanisms of Olivine and Diopside at Mercury's Reducing Conditions

Journal of Geophysical Research: Planets, Volume 131, Issue 11, November 2026.
Abstract The surface of Mercury contains elevated amounts of sulfur of up to 4 wt.%. Volcanic degassing of S from the interior of the planet could have initiated sulfidation reactions between the degassed S and surface materials in the planet's past, leading to the observed surface S enrichment.

Elevation‐Dependent Hydroclimatic Constraints on Millennial Growth of Pinus flexilis Across Its Ecological Amplitude in the Greater Yellowstone Ecoregion

Journal of Biogeography, Volume 53, Issue 11, November 2026.
ABSTRACT Aim We tested how climate–growth relationships, temporal coherence and responses to compound climate extremes vary across a regional elevational gradient occupied by Pinus flexilis. Location Greater Yellowstone Ecoregion, northwestern Wyoming, USA.
