Perchlorates on Mars enhance the bacteriocidal effects of UV light
Scientific Reports, 2017 Perchlorates have been identified on the surface of Mars. This has prompted speculation of what their influence would be on habitability. We show that when irradiated with a simulated Martian UV flux, perchlorates become bacteriocidal.

Martian north polar cap summer water cycle
, 2016 A key outstanding question in Martian science is 'are the polar caps gaining or losing mass and what are the implications for past, current and future climate?' To address this question, we use observations from the Compact Reconnaissance Imaging ...

Raman Spectroscopic Analysis and In Situ Heating Experiments on Adranosite Minerals
Journal of Raman Spectroscopy, Volume 57, Issue 2, Page 343-359, February 2026.This study provides the first detailed Raman spectroscopic characterization of rare ammonium sulfates adranosite, iron‐rich adranosite, and adranosite‐(Fe) from volcanic and coal‐fire environments. Distinct spectral features reveal compositional differences and structural effects of Fe substitution.

Earth and Space Science, Volume 13, Issue 2, February 2026.Abstract The radar surface echo can be separated into coherent and incoherent components by statistical approaches, and the coherent component can be described by a backscattering model related to the RMS height. According to backscattering models for fractal surfaces, the coherent power in decibels decreases with RMS height on a scale independent of ...
