Devonian bryozoan extinction and diversification

open access: yes, 1992
The names proposed world-wide for Devonian bryozoans have been evaluated with respect to replaced names, synonyms, and nomina dubia [Horowitz and Pachut (1993), Journal of Paleontology, in press].

Fish Scales: A Multifunctional Biomaterial from Nature

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 5, September 2026.
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

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 3, September 2026.
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.

Mineral Composition and Morphology of Dolocretes of the Devonian Burtnieki and Amata Formations, Latvia

open access: yes
Siliciclastic deposits of the Burtnieki Formation and the Amata Formation in Latvia contain carbonate inclusions in places. Morphological peculiarities and mineral composition indicate that these carbonates represent dolocretes formed during subaerial ...

Comparative Morphology and Mechanics of Aquatic and Terrestrial Feeding Salamanders

open access: yesJournal of Morphology, Volume 287, Issue 9, September 2026.
Jaw muscle size, bite force, and skull strength are driven by multiple factors, not just the difference between the two habitats. Necturus produces higher bite forces than Salamandra, but the stress distribution is less even in Necturus, suggesting Salamandra's skull shape is better adapated to resist feeding loads.

G2‐PASE: A Novel, Rapid, and Reliable Measure of Plaque Psoriasis Severity

open access: yesJEADV Clinical Practice, Volume 5, Issue 3, Page 906-911, September 2026.
ABSTRACT Background The Psoriasis Area and Severity Index (PASI), a composite measure of plaque psoriasis disease severity, is commonly used to determine treatment eligibility and response, but is time consuming for every‐day clinical use. The Gulliver‐Gestalt‐Psoriasis Area Severity Estimate (G2‐PASE) was developed to approximate PASI scores using ...

Adaptation of OXPHOS biogenesis to cellular requirements

open access: yesProtein Science, Volume 35, Issue 9, September 2026.
Abstract Metabolic cues regulate the formation of the mitochondrial OXPHOS machinery. These regulatory processes are tightly linked to mitochondrial translation, proteolytic degradation of unassembled subunits, and the formation of supercomplexes, creating checkpoints at which nutrient availability, oxygen tension, and signaling pathways remodel OXPHOS

Geochronological Constraints on Diachronous Post‐Collisional Slab Breakoff Along the Paleo‐Tethyan Sutures

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.
Abstract The slab breakoff model is a preferred geodynamic interpretation for post‐collisional exhumation and associated magmatic flare‐ups. In this study, rutile U–Pb dating of retrograde eclogites revealed distinct stages of exhumation along the Paleo‐Tethyan sutures in southwest China. The studied samples yielded ages of 246.7 ± 8.5 and 239.7 ± 14.0
