Viral Nervous Necrosis due to Betanodavirus: A Case Study in Pot‐Bellied Seahorses (Hippocampus abdominals)

open access: yesJournal of Fish Diseases, EarlyView.
ABSTRACT Betanodaviruses, members of the Nodaviridae family, are the causative agents of viral nervous necrosis in fish, resulting in great economic losses worldwide. This is the first case study describing the detection and confirmation of viral nervous necrosis in pot‐bellied seahorses (Hippocampus abdominalis) in Australia.

Model Choice Matters for Age Inference on the Red Giant Branch

open access: yesThe Astrophysical Journal
Galactic archaeology relies on accurate stellar parameters to reconstruct the Galaxy's history, including information on stellar ages. While the precision of data has improved significantly in recent years, stellar models used for age inference have not ...

Pra‐GE‐ATLAS: Empowering Pinus radiata stress and breeding research through a multi‐omics database

open access: yesJournal of Integrative Plant Biology, EarlyView.
Gymnosperms represent molecular and ecological diversity hotspots, yet they remain understudied due to limited community resources. To address this gap, the P(inus)ra(diata)‐G(ene)E(xpression)‐ATLAS provides a refined multi‐omics platform for Pinus radiata that advances conifer research and facilitates the evaluation of conserved plant molecular ...

Evidence of Third Dredge-up in Post-AGB Stars in Galactic Globular Clusters

open access: yesThe Astrophysical Journal
To better understand the mixing and mass loss experienced by low-mass stars as they ascend the asymptotic giant branch (AGB), I have gathered from the literature the abundances of CNO and s -process elements in post-AGB stars in Galactic globular ...

Stellar Ages of TESS Stars, Adopting Spectroscopic Data from Gaia GSP-Spec

open access: yesGalaxies
The Gaia DR3 GSP-spec/TESS (GST) catalog combines asteroseismic data from NASA’s TESS mission with spectroscopic data from ESA’s Gaia mission, and contains about 116,000 Red Clump and Red Giant Branch stars, surpassing previous datasets in size and ...

Palaeobiology and osteohistology of South African sauropodomorph dinosaurs

open access: yesJournal of Anatomy, EarlyView.
We found that the transitionary Sauropodiformes show both the traits of rapid growth of derived Sauropoda as well as interrupted growth of early branching Sauropodomorpha. There appears to be much more variation in growth dynamics of Sauropodiformes than initially thought.

The secret in their eyes: A review of the recessus orbitalis, a unique structure of flatfishes

open access: yesJournal of Anatomy, EarlyView.
The recessus orbitalis is an organ responsible for projecting the eyeball above the level of the head and is uniquely present in flatfishes. The organ consists of two interconnected chambers filled with interstitial fluid and is internally coated with smooth muscle fibers that act as a double‐pump system.
