Appraisal of Six Natural Mica Reference Materials for In Situ Rb‐Sr Geochronology
Key Points Evaluated six natural mica reference materials for in situ LA‐ICP‐MS/MS Rb‐Sr geochronology using geochemical, microstructural and isotopic characterisation. Identified robust primary reference materials: Mount Dromedary biotite (99.37 Ma) and Mica‐Fe biotite (307.75 Ma). La Posta biotite and Högsbo muscovite are suitable secondary reference

Populations of the Short‐eared Owl Asio flammeus have declined across Europe and North America, probably in response to habitat degradation driven by agricultural intensification. However, long‐term evidence linking farmland habitat change to variation in breeding density and reproductive success remains limited.

ABSTRACT In February 2025, a mortality event of unknown aetiology occurred at a hybrid grouper (Epinephelus fuscoguttatus × Epinephelus lanceolatus) aquaculture farm in southern Taiwan, with sporadic daily deaths persisting for a month. Four moribund groupers were collected over three sampling intervals for diagnostic investigation.

Abstract Eight anhydrous interplanetary dust particles (IDPs) were analyzed for their oxygen isotopic compositions and mineralogy. They show oxygen isotopic compositions from 16O‐rich to 16O‐poor, due to mixing of different reservoirs inherited from the protosolar molecular cloud and the early solar nebula.

Lunar impact history recorded by melt beads from Apollo 17 regolith 76501
Abstract Rapidly quenched particles of melt formed as ejecta from meteoritic impacts are ubiquitous in the lunar regolith. Isotopic and geochemical data for impact‐produced glassy particles from Apollo 17 regolith sample 76501 document their major and trace element compositions and U–Pb chronologies. Their U–Pb isotopic compositions are consistent with

The cyanobacterium Anabaena uses pleomorphism as an acclimation strategy to high‐light stress
The cyanobacterium Anabaena exhibits remarkable morphological plasticity in response to changes in light intensity. These reversible changes are associated with the repositioning of thylakoids within the cytoplasm. Here, we show that cell morphology is determined by the balance between the activities of two peptidoglycan assembly systems, the ...
