Histology and fossil diagenesis of a pterosaur tooth from the Crato Formation (Lower Cretaceous of Brazil)

open access: yesThe Anatomical Record, Volume 309, Issue 10, Page 2739-2751, October 2026.
Abstract Pterosaur dental biology remains poorly understood despite its importance for comprehending feeding strategies and flight adaptations. Here, we present the first comprehensive histological analysis of an ornithocheiriform pterosaur tooth from the Lower Cretaceous Crato Formation (Santana Group, Northeast Brazil).

Spinal Mechanisms of Testosterone Involved in Itch Regulation

open access: yesCNS Neuroscience &Therapeutics, Volume 32, Issue 10, October 2026.
Testosterone serves as an endogenous anti‐pruritic hormone underlying sex‐dependent itch differences. In the spinal dorsal horn, testosterone binds androgen receptors on GABAergic interneurons to enhance GABA release, suppressing GRPR+ − pruriceptive neurons through GABAA receptors and alleviating acute/chronic itch alongside itch‐comorbid anxiety ...

Weed Seeds in New Zealand Vegetable Seed Lots: Evaluating Seed Cleaning Effectiveness From Commercial and Biosecurity Perspectives

open access: yesNew Zealand Journal of Agricultural Research, Volume 69, Issue 5, October 2026.
Weed seed contamination in vegetable seed lots poses risks to commercial seed quality and biosecurity, yet few studies have examined contamination in vegetable crops, and none have compared pre‐ and post‐cleaning levels using quantitative seed counts. We analysed 1,322 field‐dressed (FD) and machine‐dressed (MD) purity test results from four vegetable ...

Motor Cortex Hyperexcitability Is Coupled to Neuromuscular Dysfunction in Aged Mice

open access: yesAging Cell, Volume 25, Issue 10, October 2026.
Aged mice exhibited impaired motor behavior and neuromuscular hypoexcitability, yet cortical output to muscle was enhanced, and motor cortex layer V pyramidal neurons were hyperexcitable, with altered synaptic inputs and excitability‐related transcriptional changes.

Impacts of RMP toroidal phase on ELM mitigation and impurity control in EAST

open access: yesNuclear Fusion
An integrated modeling study, coupling the MARS-F code with the EMC3-EIRENE code, has been performed to examine the impacts of the toroidal phase (Δ φ ) of resonant magnetic perturbation (RMP) on edge-localized mode (ELM) mitigation and impurity control ...
