Histovariability and fossil diagenesis of Pissarrachampsa (Pseudosuchia, Notosuchia, Baurusuchidae) from the Upper Cretaceous of Southeast Brazil. [PDF]
Anat Rec (Hoboken)Abstract Notosuchians were key components of western Gondwanan Cretaceous ecosystems in terrestrial predator niches and exhibited remarkable taxonomic and ecological diversity. Previous research has explored their physiology, metabolism, and histology, revealing varied growth patterns and life history strategies.

Boosting Fast-Charging Performance of Ni-Rich NCM9055 Cathodes with Nb<sub>2</sub>O<sub>5</sub> Dual Functional Modification. [PDF]
Adv Sci (Weinh)A dual‐functional Nb2O5 modulation strategy is reported to overcome kinetic limitations in Ni‐rich cathodes. The formation of LiNbO3 phase at the grain boundary of the polycrystalline NCM9055 cathode preserves a radially aligned microstructure and establishes fast lithium‐ion pathways.

Transcriptomic, proteomic and biochemical comparison of luminescent and non-luminescent Keroplatinae larvae (Diptera: Keroplatidae). [PDF]
Insect Mol BiolTranscriptomic and proteomic comparison of luminescent O. fultoni and non‐luminescent Neoditomyia sp show that the substrate binding fraction (SBF) has a similar abundance of hexamerins and the presence of flavin‐dependent reductases. In addition to the high content of keroplatin, SBF also contains considerable amounts of riboflavin and displays ...
