Aeolian and Biogeochemical Transformations of Detrital Gold Morphology in the Pool Burn Basin, Central Otago, New Zealand

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
The Pool Burn basin is a tectonic depression that became almost isolated from the regional drainage system by river reorientation during Pleistocene uplift of surrounding ridges. Consequently, detrital gold in the basin was largely locally derived, from supergene zones on orogenic deposits and recycled from paleoplacers in erosional remnants of Miocene

Cultivar‐Specific and Field Site–Specific Protein and Metabolite Patterns of Faba Bean (Vicia faba L.) Seeds

Legume Science, Volume 8, Issue 1, March 2026.
ABSTRACT Sustainable agriculture is an important component of current and future food production, particularly in the face of the rising human world population. In this context, faba bean (Vicia faba L.) is highly valuable due to its capability to enrich soils with nitrogen and because its seeds have a high nutritional value. In this study, we compared

Practical Applications of Secondary/Extractive Electrospray Ionization (SESI): A Versatile Tool for Real‐Time Chemical Analysis

Mass Spectrometry Reviews, Volume 45, Issue 2, Page 392-428, March/April 2026.
ABSTRACT In the 1980s, researchers discovered the remarkable ability of electrospray plumes to effectively ionize gas‐phase molecules via secondary ionization. Around 20 years later—coinciding with the ambient mass spectrometry revolution—secondary electrospray ionization (SESI) and extractive electrospray ionization (EESI) coupled to mass spectrometry

Aqueous Alteration in the Kuiper Belt: Evidence from Hydrated Interplanetary Dust Particles [PDF]

Edgeworth-Kuiper belt objects (EKBOs) formed in the outer reaches of the protoplanetary disk and thus avoided much of the high tempera-ture processing experienced by bodies in the inner solar system.

Frozen Soil Hydrological Processes and Their Effects: A Review and Synthesis

Reviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract Frozen soils, including seasonally frozen ground and permafrost, are rapidly changing under a warming climate, with cascading effects on water, energy, and carbon cycles. We synthesize recent advances in the physics, observation, and modeling of frozen‐soil hydrology, emphasizing freeze–thaw dynamics, infiltration regimes and preferential flow,
