An Aeolian Depositional Sequence Shaped by Near‐Surface Water at the Base of the Layered Sulfate Unit, Gale Crater, Mars

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract The basal strata of the orbitally defined Layered Sulfate unit (LSu) in Gale crater, Mars, marks the end of a major mineralogical transition from clay‐to sulfate‐bearing stratigraphy. This has previously been attributed to a period of significant aridification of Gale's climate. Here, we present ground‐based observations by the Curiosity rover

Appetitive responses toward smoking‐related stimuli in abstinence‐motivated, non‐deprived individuals with chronic tobacco dependence: A multi‐methodological investigation

open access: yesAddiction, Volume 121, Issue 5, Page 1140-1152, May 2026.
Abstract Background and aims Appetitive responses, such as approach biases, are thought to play a crucial role in smoking. This study aimed to compare responses toward smoking‐related stimuli with responses in control conditions (e.g. non‐approach or neutral stimuli) using a multi‐method approach. By examining associations between response measures and
