DNA methylation adds an important layer of information to studies of plant diversity, adaptation, and crop improvement. However, genome-wide methylation profiling often relies on standardized commercial workflows optimized for a limited number of model or well-established species...

Alternative splicing is a key regulatory mechanism known to be altered upon viral infection. These alterations can arise both from direct viral interference with the splicing machinery and from cellular responses such as activation of innate immunity. Here, we investigated splici...

Background: Latent tuberculosis infection (LTBI) remains a global health challenge, in part due to the ability of Mycobacterium tuberculosis (Mtb) to persist within granulomatous lesions where drug exposure may be limited. Because granulomas are heterogeneous structures composed...

Abstract Photocatalytic nitrogen conversion over iron oxide-based materials remains challenging, particularly under gas-phase conditions, where reaction pathways and product distributions are poorly understood. Herein, nanostructured Fe2O3 and metal-modified Fe2O3 photocatalysts...

Background: Decidualization alters the endometrial stromal cells (EnSC) secretome, allowing sterile inflammation associated with embryo implantation, but mechanisms that lead to alterations in this process are still unknown. We evaluated whether impaired IRE1α-mediated endoplasmi...

Background: Adipose tissue (AT) has emerged as a metabolically active component of the breast tumor microenvironment that contributes to breast cancer (BC) progression. Adipocytes release adipokines and lipids that influence tumor growth; however, the specific lipolytic proteins...

Assessment of adult structural plasticity in Drosophila neurons
Unravelling how adult neurons reshape their architecture is key to understanding post-developmental plasticity. Drosophila clock neurons, which remodel their terminals on a daily basis, offer a unique model to examine the mechanisms underlying structural plasticity. In this study...

The actin/spectrin membrane-associated periodic skeleton (MPS) is a cytoskeletal structure that supports axonal integrity and function. Lower spinal motor neurons (MNs) are characterized by exceptionally long axons and are particularly susceptible to degeneration in a wide range...

Abstract Background Dioctophyme renale , known as the “giant kidney worm,” is a parasitic nematode of significant medical and biological importance due to its large size and complex interactions with various mammals, including humans, causing dioctophymiasis. Despite its importan...

Abstract We investigate the origin of the scatter in supermassive black hole (BH) masses among L⋆ galaxies, using the ARTEMIS and EAGLE simulations. We classify galaxies by their central BH-to-stellar mass ratios and track systems with the lowest and highest ratios (LBH and HBH,...

Abstract Early soluble intermediates in amyloid formation are difficult to characterize because they are transient and obscured by competing insoluble aggregation. Here, we use scE2C, an engineered covalently linked version of the HPV16 E2 DNA-binding dimer, as a tractable model...

Nursery habitats sustain fish populations by supporting early life stages and buffering environmental variability, yet their functioning under climate oscillations remains poorly understood in the Eastern Tropical Pacific. We analyzed ichthyoplankton assemblages in the Gulf of To...

This study characterizes the cytogenetic diversity of maize landraces from Northern Argentina, a region comprising Northwestern Argentina (NWA) and Northeastern Argentina (NEA). New data from four NWA landraces were analysed using DAPI banding, fluorescence in situ hybridization...

Abstract Major radiations have given rise to huge swathes of life on Earth, and understanding their dynamics reveals the process of biodiversity generation itself. The rise of dinosaurs and other archosaurs during the Triassic was a spectacular example of such a radiation; it set...

Context Protected areas (PAs) receive visitors pursuing environmental education and recreation objectives, but this can negatively affect the conservation of their biodiversity. Quantification of this impact is scarce, especially in developing countries. The Anthropause generated...

Abstract Background Ant communities are widely considered to be structured by interspecific competition. Seed-harvesting ants are dominant granivores in drylands, and their colony locations influence their spatio-temporal effect on plant communities. Three closely related species...

EFECT enables reliable and reproducible stochastic simulations across disciplines
Stochastic simulations underpin computational research in fields from systems biology and epidemiology to finance and physics-informed machine learning, yet their reproducibility is hard to quantify because each run yields different outcomes. Existing practices to improve computa...

The Beagle Channel, located south of Tierra del Fuego (~54° S), is South America’s southernmost intracoastal ecosystem. Here, we applied environmental DNA metabarcoding using a partial sequence of the 12sRNA mitochondrial gene to evaluate the seasonal and spatial dynamics of mari...
