Transposable Element Dynamics Drive the Genomic Evolution and Phenotypic Diversification of Allotetraploid Common Carp

open access: yesAdvanced Science, EarlyView.
By integrating 516 whole‐genome resequencing datasets and 236 transcriptomes of allotetraploid common carp, this study establishes the first population‐scale atlas of transposable element (TE) variation in teleost species. TE bursts, relaxed purifying selection, and lineage‐specific loss of ancient insertions shape genome evolution and phenotypic ...

Bacteria‐Derived 1‐Allylpiperazine Alleviates Symptoms of Parkinson's Disease Model by Promoting Autophagy

open access: yesAdvanced Science, EarlyView.
Parkinson's disease currently has no disease‐modifying therapies. In Caenorhabditis elegans, Escherichia coli E8 alleviates α‐synuclein‐provoked PD‐related defects through its bioactive metabolite 1‐ALPP, which combats PD by triggering AMPK/mTOR/HLH‐30‐dependent autophagy and suppressing α‐synuclein LLPS‐mediated fibrillization.

Delaying the Inevitable? U.S. Screwworm Closures and Feeder Cattle Market Dynamics

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT Biosecurity trade restrictions are commonly framed as preventive measures, yet in many settings they function primarily as policies of delay: they impose immediate market costs while only postponing the arrival of biological risks. This paper evaluates that intertemporal tradeoff using the 2024–2025 US suspension of live cattle imports from ...

Cell Segmentation Beyond 2D—A Review of the State‐of‐the‐Art

open access: yesAdvanced Intelligent Discovery, EarlyView.
Cell segmentation underpins many biological image analysis tasks, yet most deep learning methods remain limited to 2D despite the inherently 3D nature of cellular processes. This review surveys segmentation approaches beyond 2D, comparing 2.5D and fully 3D methods, analyzing 31 models and 32 volumetric datasets, and introducing a unified reference ...
