Ancient Mars Climate With a Polar Ocean and Ice Sheet Dynamics
Journal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.Abstract In this article, we study the conditions required to maintain a stable ocean on Mars 3 Ga using a new suite of simulations. These simulations couple a 3D Global Climate Model with ocean dynamics and ice sheet flow. The model includes the main processes of the atmosphere/hydrosphere/cryosphere to investigate Mars' ancient climate.

An Unexpected Facet of Extremophiles: Their Aesthetic Potential in Artistic Expression
Microbial Biotechnology, Volume 18, Issue 10, October 2025.In an era marked by environmental challenges and the proliferation of misinformation, the fusion of art and science is a strategy to promote public understanding and appreciation of complex scientific phenomena. We illustrate how the use of extremophiles offers novel avenues for artistic exploration and emphasise the benefits of such interdisciplinary ...

Environmental Microbiology Reports, Volume 17, Issue 5, October 2025.This study describes an endolithic microbial community primarily composed of the cyanobacterial taxon Chroococcidiopsis, along with comprehensive data regarding the local geological and microclimatic factors that affect this distinct ecosystem. Metagenomic analysis identified genes associated with adaptive mechanisms for extreme aridity, with sporadic ...

The Desert in Bottles: The Culturable Microbiome of the Atacama Desert's Grit Crust
Environmental Microbiology Reports, Volume 17, Issue 5, October 2025.The grit crust represents a unique biocrust type of the coastal Atacama Desert. Cyanobacteria, green algae and free‐living fungi were isolated along a fog gradient. Phylogenetic relationships indicated novel taxa and framed an indigenous microbiome. Microclimate and soil data support functional groups related to sites.

The evolution of reproduction in Ediacaran–Cambrian metazoans
Biological Reviews, Volume 100, Issue 5, Page 2084-2098, October 2025.ABSTRACT The evolution of reproductive style is a fundamental aspect of metazoan life history but has not been explored holistically through the Ediacaran–Cambrian rise of metazoans. Recent molecular clock analyses based on only unequivocal metazoan fossil calibrations suggest that Porifera were present by at least 590 million years ago (Ma), all major
