Metamorphic or Igneous Zircon? Classification Through Rare Earth Elements, Machine Learning and Logistic Regression

Journal of Metamorphic Geology, Volume 44, Issue 9, Page 665-682, November 2026.
ABSTRACT Zircon is a common, highly refractory accessory mineral found in sedimentary, igneous and metamorphic rocks that forms through various processes (e.g., magmatic, hydrothermal, metamorphic growth and recrystallization). Trace element compositions of detrital zircon have been widely applied to understanding tectonic processes and continental ...

Genomic Divergence and Variation in Developmental Plasticity Across Inselberg Populations of a Tropical Frog

Molecular Ecology, Volume 35, Issue 21, November 2026.
ABSTRACT Understanding how phenotypic plasticity and local specialization are shaped by gene flow and environmental heterogeneity requires natural systems that vary in both spatial isolation and environmental conditions across the landscape, yet such systems are uncommon. Naturally discontinuous inselbergs may provide this opportunity.

Long‐term persistence of Sox10CreERT2‐driven reporter labeling in enteric glia of mice under physiological and inflammatory conditions

Physiological Reports, Volume 14, Issue 21, November 2026.
Sox10CreERT2‐driven tdTomato reporter labeling in enteric glia remained stable for up to 7 months under physiological conditions and was maintained for 1 month following DSS‐ or DNBS‐induced intestinal inflammation. Abstract Inducible Cre‐lox systems are widely used to manipulate enteric glia in vivo.

Effect of Laboratory Reagents for Cleaning Modern Contamination on the δ15N Integrity of Nitrogen‐Poor Samples

Rapid Communications in Mass Spectrometry, Volume 40, Issue 19, 15 October 2026.
ABSTRACT Rationale Nitrogen isotope values have been widely used for tracing ancient biogeochemical processes, but contaminant‐sensitive materials, such as Precambrian sedimentary rocks, meteorites, or returned extraterrestrial samples, often have low nitrogen levels and are thus vulnerable to modern organic contamination.

Tracing back sulfur isotope reequilibration due to contact metamorphism: A case study from the Perubar VMS deposit, Central Peru

, 1999
The mid-Cretaceous Perubar VMS deposit, Central Peru, affected by contact metamorphism, has been the subject of a sulfur isotope investigation. The measured δ34S values for sulfate-sulfide pairs from the deposit indicate that close to equilibrium ...

Matrix Metalloproteinase‐8 Deficiency Alters the Balance Between Viral Clearance and Immunopathology in H1N1 Infection

The FASEB Journal, Volume 40, Issue 19, 15 October 2026.
Mmp‐8 deficiency during H1N1 influenza infection enhances Type I interferon responses, necroptosis‐associated signaling, and adaptive immunity, leading to lower lung viral burden and improved survival, but also amplifies inflammatory lung injury. ABSTRACT Matrix metalloproteinase‐8 (MMP‐8) regulates inflammatory responses, but its contributions to the ...
