Obscuration of Crystalline Ca‐Sulfate in XRD and Raman Data When Coated by Amorphous Ferric Sulfate: Implications for the Amorphous Components at Gale Crater

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract Throughout Gale crater on Mars, the Curiosity rover has found high abundances (15–73 wt%) of X‐ray amorphous materials in the rocks and sediments. The composition of this amorphous fraction is primarily calculated by subtracting crystalline abundances measured by the Chemistry & Mineralogy X‐Ray Diffractometer (CheMin) from bulk elemental ...

pygid: a Python package for fast data reduction in grazing‐incidence diffraction

open access: yesJournal of Applied Crystallography, Volume 59, Issue 1, Page 263-275, February 2026.
A new Python package, pygid, enables fast batch processing of X‐ray scattering data, with a particular focus on grazing‐incidence geometries.Advances in X‐ray and neutron sources, as well as in area‐detector technologies, enable the recording of several terabytes of raw two‐dimensional detector data in a single experiment.

Ascorbate peroxidase modulation confirms key role in Leishmania infantum oxidative defence

open access: yesParasites & Vectors
Background Ascorbate peroxidase (APX) has emerged as a promising target for chemotherapy because of its absence in humans and crucial role in the antioxidant defence of trypanosomatids.

Systemic Activation of the Antioxidant System by Root Priming With Non‐Pathogenic Fusarium oxysporum in Flax Infected With Pathogenic Fusarium oxysporum

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 1, February 2026.
Fusarium oxysporum Fo47 primes flax by locally suppressing pathogens in roots and systemically activating antioxidant defences in shoots, offering a sustainable plant protection strategy. ABSTRACT Plants rely on specialised adaptive mechanisms to enhance resistance against environmental stress.

Methyl jasmonate fumigation enhances crop yield and delays physiochemical quality changes by modulating the secondary metabolism in green bell pepper

open access: yesJournal of the Science of Food and Agriculture, Volume 106, Issue 1, Page 55-72, 15 January 2026.
Abstract BACKGROUND The green bell pepper (Capsicum annuum L.), of the ‘Lamuyo’ type, is a highly valued vegetable owing to its excellent organoleptic and nutritional properties. However, these properties are subject to deterioration during postharvest storage, which in turn limits the shelf‐life of the pepper fruit.

Regulatory Effect of Spermine on Growth and Antioxidant System in Tomato Seedlings Grown in the Presence of Cadmium [PDF]

open access: yesJournal of Stress Physiology & Biochemistry, 2019
The protective role of exogenous supplied polyamines such as spermine in detoxifying the cadmium induced toxicity was studied in the tomato plants Solanum lycopersicum, we applied a dose of (1 mM) spermine with cadmium (0, 20 and 100 µM) for 7 days.
