Investigating the Atmospheric Microbial Ecosystem Through Theory, Bioenergetics, and Numerical Modeling: A Breath of Fresh Air for Aeromicrobiology

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 130, Issue 8, August 2025.
Abstract The atmosphere may constitute the Earth's largest microbial ecosystem, yet it remains the least understood. While microorganisms can persist and may even thrive in the polyextremes of the Earth's atmosphere, it is still unknown whether the atmosphere sustains an active microbial community.

Influence of Orbit and Mass Constraints on Reflected Light Characterization of Directly Imaged Rocky Exoplanets

open access: yesThe Astrophysical Journal Letters
Survey strategies for upcoming exoplanet direct imaging missions have considered varying assumptions of prior knowledge. Precursor radial velocity surveys could have detected nearby exo-Earths and provided prior orbit and mass constraints. Alternatively,

Investigating the D" Reflector Beneath the Indian Ocean with Source Arrays

open access: yesSeismica
We used seismic P-wave reflections to search for the discontinuity at the top of the D" region beneath the Indian Ocean. Due to a lack of seismic receiver arrays to target this region, we build source arrays using earthquakes in Indonesia and taking ...

Opportunities, research gaps, and risks in allogenic ecosystem engineer mimicry

open access: yesConservation Biology, Volume 39, Issue 4, August 2025.
Abstract In an age of anthropogenically driven species loss and increasingly novel ecosystems, ecosystem engineer restoration is a process‐based approach to supporting ecosystem function. Many ecosystem engineers have low or declining population sizes.

Effects of Planetary Mass Uncertainties on the Interpretation of the Reflectance Spectra of Earth-like Exoplanets

open access: yesThe Astronomical Journal
Atmospheric characterization of Earth-like exoplanets through reflected light spectroscopy is a key goal for upcoming direct imaging missions. A critical challenge in this endeavor is the accurate determination of planetary mass, which may influence the ...

Collective Science to Inform Global Ocean Protections

open access: yesEcology Letters, Volume 28, Issue 8, August 2025.
Signatories are poised to ratify the UN High Seas Treaty, providing a legal mechanism to create protected areas in our greatest global commons. Robust, publicly accessible biodiversity data is needed to enable effective and equitable proposals for protection under the treaty but is relatively scarce, particularly at depth.

Simulating evaporative wet and dry cycles in Gale crater, Mars using thermochemical modeling techniques

open access: yesMeteoritics &Planetary Science, Volume 60, Issue 8, Page 1704-1720, August 2025.
Abstract The aim of this work is to provide a model‐backed hypothesis for the formation of evaporites—sulfates, borates—in Gale crater using thermochemical modeling to determine constraints on their formation. We test the hypothesis that primary evaporites required multiple wet–dry cycles to form, akin to how evaporite assemblages form on Earth ...

Disasters, Food Rescue and Infrastructure for Recovery

open access: yesNew Zealand Geographer, Volume 81, Issue 2, Page 81-90, August 2025.
ABSTRACT Disasters can wreak havoc on food systems, triggering cascading negative impacts, particularly for people with the least resources to recover. While disaster risk reduction (DRR) guidance recognises that inequalities are compounded during disasters, critics suggest that much DRR practice still focuses on individual preparation unavailable to ...
