Comparing Geochemical and Geodynamical Models of Plume and Ridge Mantle Source Composition

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 8, August 2025.
Abstract We use a multidisciplinary approach to investigate how the parameter space of mantle convection affects present‐day mantle composition. We compare 22 forward geodynamical mantle circulation model simulations against 24 variants of a geochemical inversion model of the global radiogenic isotope data set of mantle‐derived lavas.

Where Are the Water Worlds? Identifying Exo-water-worlds Using Models of Planet Formation and Atmospheric Evolution

The Astrophysical Journal
Planet formation models suggest that the small exoplanets that migrate from beyond the snowline of the protoplanetary disk likely contain water-ice-rich cores (∼50% by mass), also known as water worlds.

Boundaries of photosynthesis: adaptations of carbon fixation in extreme environments

FEBS Open Bio, Volume 15, Issue 7, Page 1028-1040, July 2025.
Photosynthesis faces challenges from environmental extremes of temperature, pH, and salinity, limiting gas diffusion, modifying membrane fluidity, and destabilizing photochemical and biochemical reactions. Photosynthetic organisms have evolved unique adaptations overcoming these stresses and maintaining their photosynthetic activity.

The Cosmic Shoreline Revisited: A Metric for Atmospheric Retention Informed by Hydrodynamic Escape

The Astrophysical Journal
The “cosmic shoreline,” a semi-empirical relation that separates airless worlds from worlds with atmospheres as proposed by K. J. Zahnle & D. C. Catling, is now guiding large-scale JWST surveys aimed at detecting rocky exoplanet atmospheres.

JWST/NIRISS Reveals the Water-rich “Steam World” Atmosphere of GJ 9827 d

The Astrophysical Journal Letters
With sizable volatile envelopes but smaller radii than the solar system ice giants, sub-Neptunes have been revealed as one of the most common types of planet in the galaxy. While the spectroscopic characterization of larger sub-Neptunes (2.5–4 R _⊕ ) has
