Salt Range Formation of Pakistan Preserves Unique Record of Volcanic Fertilization During the Ediacaran Shuram Excursion

open access: yesTerra Nova, Volume 38, Issue 6, Page 368-375, December 2026.
ABSTRACT Thin, discontinuous, organic‐rich oil shale beds in the siliciclastic‐evaporitic Salt Range Formation (SRF) of Pakistan are of approximate Neoproterozoic to Cambrian age based on stratigraphic constraints. The beds are enriched (26–43 wt.% total organic carbon, TOC) in aliphatic organic matter (OM) of low thermal maturity despite their ...

Reconstruction of Rock Uplift in South‐Central Germany Since Late Mesozoic Times

open access: yesGeophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract Rock uplift and denudation act as first‐order controls on geological processes that influence atmospheric and ocean composition, and landscape‐forming processes. However, estimating rock uplift rates remains challenging due to the temporal averaging of rates calculated from individual thermo‐ or geochronologic systems.

Feasibility and Limitations of the Advanced Replica Process for Bioactive Glasses

open access: yesAdvanced Engineering Materials, Volume 28, Issue 21, 4 November 2026.
Periodic 3D‐printed Kelvin‐cell templates enable a controlled advanced replica process for fabricating highly porous glass lattices. Across P45K9, 45S5, and 13–93, material‐dependent differences in coating, burnout, and shrinkage lead to distinct strut morphologies, while comparable final porosities of 83%–88% are retained.

Leveraging Multi‐Isotope Systems to Investigate Conflict, Food Insecurity, and Elevated Nitrogen Isotope Values in the Nazca Highlands of Peru During the Late Intermediate Period (1000–1450 CE)

open access: yesAmerican Journal of Biological Anthropology, Volume 191, Issue 3, November 2026.
ABSTRACT Objectives The physical effects of interpersonal violence are well documented in archaeology, but its broader impacts on population health, mobility, and resource access remain less understood. This article assesses how chronic warfare restricted movement and access to critical resources, altering dietary practices and contributing to ...

Chitosan‐Based Hydrogels for Periodontal Therapy: From Drug‐Polymer Chemistry to Smart Multifunctional and Regenerative Systems

open access: yesChemistry &Biodiversity, Volume 23, Issue 11, November 2026.
Chitosan‐based hydrogels are evolving from simple local drug carriers into multifunctional periodontal platforms that integrate antimicrobial, anti‐inflammatory, antioxidant, and regenerative functions. Chemical crosslinking, nanocomposite design, and stimulus‐responsive architectures enable adaptive therapeutic delivery.

Disentangling the depositional, tectonic and diagenetic history of a unique case of rhombic calcite in marine carbonate scree‐like deposits in the Cretaceous Cauvery Basin

open access: yesThe Depositional Record, Volume 12, Issue 5, November 2026.
A succession of marine deposited scree deposits got exposed to meteoric fluids due to sea level drop or tectonic uplift. This potentially caused a unique form of diagenetic transformation in scree deposits, that is the formation of micro rhombic calcite.
