Global Model Estimates of Atmospheric Al, Ca, Fe, Si, and Ti From Dust and Non‐Dust Aerosols Informed by EMIT Surface Mineralogy and Evaluated Against Observations

Global Biogeochemical Cycles, Volume 40, Issue 5, May 2026.
Abstract Atmospheric deposition of micro‐nutrients like Fe has been shown to be important for ocean biogeochemistry. The largest source of atmospheric Fe and other elements (e.g., Ca, Al, Si, and Ti) is desert dust, although there are significant non‐dust sources in some regions (e.g., combustion, sea salts, volcanoes). However, past estimates of these

Spectroscopic techniques in the investigation of extraordinary medieval Polish coins: Revealing the presence of hidden cores

Nukleonika
Cross denars, frequently found in Polish hoards, were traditionally thought to be Ag coins with some Cu content. This study investigates the possibility of a hidden Cu core beneath the Ag or Ag–Cu surface of these coins. It raises questions about whether

X‐ray Fluorescence Microscopy Computed Tomography Reveals Internal Distribution of Selenium in Hyperaccumulator Plant Seeds

Ecological Research, Volume 41, Issue 3, May 2026.
Selenium hyperaccumulators are plants able to accumulate over 1000 mg/kg in their shoots while growing in their natural environments. The distribution of selenium in the seeds of the three key hyperaccumulating species was elucidated using X‐ray fluorescence microscopy computed tomography (XFM‐CT). ABSTRACT Selenium hyperaccumulators are plants able to

Influence of Root‐Applied Glutathione on Nickel Uptake and Distribution in Brassica Roots

Ecological Research, Volume 41, Issue 3, May 2026.
This study indicates that exogenous glutathione (GSH) applied to the roots inhibits nickel (Ni) uptake and its translocation to the shoots in hydroponically grown Brassica napus. Micro‐PIXE imaging further revealed that GSH reduces Ni accumulation near the stele, indicating inhibition of Ni radial transport toward the vascular tissues.

Sourcing carnelian beads from the ancient Mesopotamian site of Kish, Iraq, 2450–2200 BCE: Stylistic, technological and geochemical approaches

Archaeometry, Volume 68, Issue S1, Page S22-S37, April 2026.
Abstract Trade between Mesopotamia and the Indus Civilization is studied through the analysis of Early Dynastic III Period (2600–2350 BCE) carnelian beads from the site of Kish, Iraq. Morphological and technological features of the beads are compared with beads from the Indus region.
