Biology Mpox Virus Impact in SIVmac239-Infected Macaques In the ever-evolving landscape of infectious diseases, the intersection of complex viral infections and immune-compromised hosts represents an urgent frontier in biomedical research. A groundbreaking study recently published in Nature Communications has provided unprecedented insights into how Mpox virus (formerly known as monkeypox virus) orchestrates multifaceted pathogenic mechanisms within immunodeficient hosts, specifically focusing on SIVmac239-infected […] Written by Bioengineer August 17, 2025August 17, 2025 Saving Bookmark this article Bookmarked
Biology Intraflagellar transport selectivity occurs within the proximal portion of the trypanosome flagellum Intraflagellar transport (IFT) trains move bidirectionally along the doublet microtubules (DMTs) of the axoneme within the flagellum. In Trypanosoma brucei, IFT trains predominantly associate with four of the nine DMTs. Using high-resolution microscopy, we reveal how this selective association is put in place. IFT proteins form a ring surrounding the 9 DMTs above the transition […] Written by Admin August 15, 2025August 15, 2025 Saving Bookmark this article Bookmarked
Biology Sarcocystis halieti DNA Found in Birds Across Europe In a groundbreaking study that reshapes our understanding of avian parasitology, researchers have successfully detected the DNA of Sarcocystis halieti—a parasitic protozoan—in the bloodstreams of several bird species across Europe. This finding not only illuminates the complex interactions between parasites and avian hosts but also raises intriguing questions about ecological dynamics, host specificity, and the […] Written by Bioengineer August 13, 2025August 13, 2025 Saving Bookmark this article Bookmarked
Biology Context is everything: The role of polo-like kinase I during C. elegans oocyte meiosis Meiotic chromosome segregation in oocytes often relies on meiosis-specific modifications of mitotic molecular mechanisms to respond to the unique challenges of this asymmetric division. In this issue, Narula and Wignall (https://doi.org/10.1083/jcb.202503080) demonstrate how the conserved polo-like kinase in Caenorhabditiselegans, PLK-1, has been repurposed in unexpected ways to ensure accurate meiotic chromosome segregation during oogenesis.

Biology Al–Salen Catalyst Powers Enantioselective Photocyclization In a groundbreaking leap for synthetic chemistry, a team of scientists has unveiled a novel strategy harnessing energy transfer to achieve enantioselective photocyclization mediated by an aluminum-salen (Al–salen) catalyst. This pioneering work, recently published in Nature Chemistry, represents a paradigm shift in the way chemists can manipulate light-induced reactions with exquisite control over stereochemistry, heralding […] Written by Bioengineer August 9, 2025August 9, 2025 Saving Bookmark this article Bookmarked
Biology SOD1 is delivered to lysosomes via autophagy to maintain lysosomal function and integrity The gene encoding superoxide dismutase 1 (SOD1) is often mutated in familial amyotrophic lateral sclerosis (ALS), affecting motor neurons. Compared with ALS-associated mutant SOD1, the function of WT SOD1 is less explored. We demonstrate that during starvation, WT and mutant SOD1 are transported into lysosomes. Genome-wide CRISPR interference (CRISPRi) screening identified autophagy-related proteins and the […] Written by Admin August 8, 2025August 8, 2025 Saving Bookmark this article Bookmarked
Biology Disordered Interfacial Water Boosts Electrochemical C–C Coupling In the relentless pursuit to combat climate change, the electrochemical conversion of carbon dioxide (CO₂) and carbon monoxide (CO) into value-added, energy-rich multi-carbon products has emerged as a beacon of hope. These processes promise not only to mitigate greenhouse gas emissions but also to create sustainable fuel alternatives that could revolutionize the energy landscape.

Biology Arc spreads Crumbs: Spatial restriction of tissue invagination to form a thin epithelial tube In this issue, Kim et al. (https://doi.org/10.1083/jcb.202409078) report that the scaffold protein Arc acts through Crumbs to spatially restrict where actomyosin-based apical constriction occurs across the invaginating Drosophila salivary gland. This restriction is needed for a long, thin tube to form. Written by Admin August 4, 2025August 4, 2025 Saving Bookmark this article Bookmarked
Biology Dental Stem Cells Differentiate on Biodentine Nanofibers In a groundbreaking advance within the field of regenerative medicine, researchers have unveiled a novel approach to enhance dental and bone tissue engineering by leveraging the unique properties of dental pulp stem cells (DPSCs) cultured on specially designed polymer nanofibers.

Biology AI-directed voxel extraction and volume EM identify intrusions as sites of mitochondrial contact Membrane contact sites (MCSs) establish organelle interactomes in cells to enable communication and exchange of materials. Volume EM (vEM) is ideally suited for MCS analyses, but semantic segmentation of large vEM datasets remains challenging. Recent adoption of artificial intelligence (AI) for segmentation has greatly enhanced our analysis capabilities. However, we show that organelle boundaries, which […] Written by Admin July 31, 2025July 31, 2025 Saving Bookmark this article Bookmarked
