eDNA surveys expand known marine fish ranges

Global species records often underestimate marine fish distributions due to sampling biases, especially in remote regions. Loïc Sanchez, Stéphanie Manel and colleagues show that environmental DNA surveys significantly expand known geographic and ecological niche ranges, revealing hidden biodiversity and improving predictions for conservation and ecological modeling. Don't miss the Primer by Jonathan Belmaker.

Meta-Research Article

High rate of image manipulation in published papers

Unchallenged erroneous articles can undermine scientific progress and mislead future research. René Aquarius, Kimberley Wever and co-workers reveal that image-related issues affect 40% of reviewed articles on early brain injury in animal studies, yet corrective actions by journals remain limited.

Mammalian antiviral proteins restrict CpG-rich avian viruses

Zoonotic influenza A viruses pose a persistent threat, yet the antiviral barriers to cross-species transmission remain unclear. Jordan Becker, Reuben Harris, Ryan Langlois and co-authors find that CpG-enriched avian viruses are restricted by several mammalian proteins, including human ZAP and platypus KHNYN.

Brain-age prediction models and disease detection

There is increasing interest in developing imaging-based models to characterize 'brain-age', but how accurate are these for predicting neurological disease? Marc-Andre Schulz, Nys Tjade Siegel and Kerstin Ritter show that simpler models, which have lower age prediction accuracy, are paradoxically more sensitive to disease-related brain changes, suggesting the field re-evaluate modeling priorities.

PRMT5 promotes breast cancer EMT and invasion via alternative splicing

PRMT5 is a histone methyltransferase upregulated in various cancer types, but its role in regulating alternative splicing events is unknown. Srinivas Abhishek Mutnuru, Sanjeev Shukla and colleagues show that PRMT5 regulates TCF3 alternative splicing under hypoxia and that this promotes EMT and invasion of breast cancer cells.

Variation in pain perception

Variability in neural activity is associated with cognition, but how this variability relates to pain is poorly understood. Li-Bo Zhang, Xin-Yi Geng and Li Hu find that neural variability correlates with how individuals perceive pain intensity in different contexts, enhancing our understanding of the neural encoding of pain.

Coordinating septum formation during cell division

Cytokinesis relies on coordinated contractile-ring constriction, vesicle trafficking, and extracellular matrix remodeling. Sha Zhang, Davinder Singh, Jian-Qiu Wu and co-workers show that the Ync13-Rga7-Rng10 module coordinates tethering and fusion of vesicles containing glucan synthases at the division site in fission yeast, ensuring proper septum formation and cell integrity during cytokinesis.
