New data on acanthodians of the Middle Devonian of the Main Devonian Field (in Russian)
New data on distribution of acanthodian taxa in the exposure of Eifelian and Givetian (Middle Devonian) deposits located in the Lemovzha River basin (Leningrad Region, Russia) is analysed with the aim to clarify the position of the Eifelian-Givetian boundary in the section.

The Magnetic Signature of Shear Zones in Marbles and Experimental Simulations
This dataset explores how strain, microstructure, texture and magnetic susceptibility interact in natural and experimental shear zones. It includes data from low‐ and high‐temperature marble shear zones and analogue experiments simulating different deformation regimes.

Middle Triassic turbidites in the Youjiang Basin were chiefly derived from a Late Palaeozoic continental arc along the southeastern South China Block, as revealed by detrital zircon U–Pb geochronology and tourmaline geochemistry, supporting a tectonic model driven by Paleo‐Pacific subduction rather than Paleo‐Tethyan closure.

Fish Scales: A Multifunctional Biomaterial from Nature
Fish scales demonstrate nature's solution to impact protection through overlapping multilayered architecture. This biological design combines mineralized surfaces with collagen networks to achieve both flexibility and fracture resistance. The structural principles inspire advanced protective materials and biomedical implants, where damage tolerance ...

Composition and Provenance of Victoria Group Sandstones in Southern North Victoria Land, Antarctica
Three distinct source areas contributed to sandstones of the Victoria Group within the Transantarctic Basin in southern North Victoria Land. During the Permian, quartzose sandstones were derived from erosion of the local Ross Orogen, likely from an uplifted swell in the area of today's Ross Sea, the Ross High.
