Formation and Alteration of Magnesite Nodules From Kunwarara, Queensland, Australia, as an Analog to Mg‐Carbonate Formation on Mars

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 9, September 2026.
Abstract Magnesite (MgCO3) is a magnesium (Mg) carbonate mineral that records the aqueous environmental conditions of its formation. On Earth, magnesite forms in metamorphic, diagenetic or pedogenic environments, and distinguishing between these environments is critical for understanding the fluid chemistry during magnesite precipitation. Mg carbonates

Which, when, and where traits matter: functional trait‐mediated species associations shift with microenvironmental and climatic variation

open access: yesNew Phytologist, Volume 251, Issue 5, Page 2468-2481, September 2026.
Community‐level fitted relationship between spatial association Lij and trait dissimilarity (tDij) at the fine spatial scale (r = 40 mm; where r represents the radius around individuals of the focal species). Summary Predicting coexistence in species‐rich plant communities requires understanding the role of functional traits in species interactions and

Female Budgerigars Attend Equally to Rhythmic Beat or Repetition, While Humans Prioritize Their Combination

open access: yesAnnals of the New York Academy of Sciences, Volume 1563, Issue 1, September 2026.
We investigated preferences of budgerigars and humans for rhythmic and arrhythmic sounds, specifically beat‐based regularity and repetition, using a place‐preference paradigm. We found that female budgerigars prefer regular and repetitive sounds equally, while humans prefer sounds containing a regular beat over repetition.

Return Migration and Contraceptive Use in Mexico

open access: yesStudies in Family Planning, Volume 57, Issue 3, Page 432-455, September 2026.
Abstract Return migration, whether voluntary or forced, can disrupt individuals’ lives as they navigate life in a country that may feel unfamiliar. This disruption often extends to healthcare, including reproductive care. The migration experience, combined with differences between healthcare systems—in terms of availability, accessibility, and ...

Corundum Discovered by SuperCam and the Perseverance Rover at Jezero Crater, Mars

open access: yesGeophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Mars is primarily composed of mafic mineral assemblages and their alteration products, but small, scattered rocks strewn across the landscape offer clues to greater petrological diversity. While traversing the Jezero crater rim, the Perseverance rover encountered several plagioclase‐rich light‐toned float rocks.
