Geochemical investigation of impactites from the Boltysh impact structure and possible relationship to early Danian sediments from the Umbria–Marche Basin, Italy

Meteoritics &Planetary Science, EarlyView.
Abstract Within the Danian Scaglia Rossa Formation appears a regionally correlatable horizon cutting across multiple sections and outcrops within the Umbria–Marche Basin of NE Italy, where it is intercalated with uniform pelagic carbonate successions. This horizon is called “ALE layer” and has tentatively been interpreted as a fine‐grained volcanic ash.

Stardust Mine: A 2024 gabbroic shergottite from Arizona, USA

Meteoritics &Planetary Science, EarlyView.
Abstract This study provides an initial characterization of Stardust Mine, a fresh gabbroic enriched shergottite collected in Arizona, USA, in September 2024 and is the first Martian meteorite to be unequivocably collected on US soil. Analysis was conducted on the type specimen and finds that Stardust Mine is composed of equal proportions of pyroxene ...

Climate conditions on the South‐Iberian Palaeomargin during the latest Pliensbachian to early Toarcian: A mineralogical and geochemical study from hemipelagic deposits

Sedimentology, EarlyView.
ABSTRACT The integrated analysis of lithofacies, mineralogy and geochemistry of the hemipelagic marine succession exposed in La Cerradura section (South‐Iberian Palaeomargin) provides new information to characterise the palaeoenvironmental conditions during the latest Pliensbachian to early Toarcian, including the Jenkyns Event.

Magmatic evolution and mineralization of the Eocene back-arc magmatic rocks from NE Iran

Journal of Asian Earth Sciences: X
The Eocene magmatism in NE Iran represents a significant component of the broader Cenozoic magmatic activity associated with the subduction of the Neotethys Ocean beneath the Iranian plateau.

Contrast Agents for Enhanced Bioimaging: A Comprehensive Review

ChemBioChem, Volume 27, Issue 13, 14 July 2026.
Contrast agents, especially those that are nanoparticle‐based, are revolutionizing bioimaging by enabling highly sensitive, specific, and early‐stage diagnosis of diseases like cancer, using clinical imaging modalities such as CT, MRI, PET, and SPECT.

Abundant Ancient Melt‐Depleted Peridotite Beneath the Marion Rise, Southwest Indian Ocean, Effects on Basalt Composition and Dynamic Topography

Geochemistry, Geophysics, Geosystems
The Marion Rise (MR) at the central Southwest Indian Ridge (SWIR) is an ultra‐slow spreading ridge with thin crust, shallow ridge depth, sparse basaltic coverage, and exposed peridotite.

Radiolabeled Angiopep‐2 Peptide Vector as a Preclinical Platform for Blood–Brain Barrier Targeting: Synthesis, Radiolabeling, and Preliminary In Vivo Biodistribution in Mice

Journal of Peptide Science, Volume 32, Issue 7, July 2026.
The developed DOTA‐Angiopep‐2 conjugate was well tolerated in glioma cells and enabled high‐yield radiolabeling with 177Lu and 161Tb. The 161Tb conjugate showed brain delivery with predominantly renal clearance, supporting a stable radiotheranostic platform for BBB‐targeted glioma therapy and SPECT imaging.

Contrasting Granite Metallogeny through the Zircon Record: A Case Study from Myanmar

Scientific Reports, 2017
Granitoid-hosted mineral deposits are major global sources of a number of economically important metals. The fundamental controls on magma metal fertility are tectonic setting, the nature of source rocks, and magma differentiation.
