Identification of organelle-specific autophagy regulators from tandem CRISPR screens

Autophagy is a conserved degradative process that promotes cellular homeostasis under stress conditions. Under nutrient starvation, autophagy is nonselective, promoting indiscriminate breakdown of cytosolic components. Conversely, selective autophagy is responsible for the specific turnover of damaged organelles. We hypothesized that selective autophagy may be regulated by signaling pathways distinct from those controlling starvation-induced autophagy, thereby […]

New Research Suggests Punitive Laws on Substance Use During Pregnancy Could

In recent years, the United States has witnessed a growing wave of legislative efforts aimed at addressing substance use among pregnant and postpartum individuals. Against this backdrop, a groundbreaking study conducted by researchers at Columbia University’s Mailman School of Public Health offers an in-depth examination of how different state legal frameworks impact maternal health outcomes.

Origin of chromosome 12 trisomy surge in human induced pluripotent stem cells

Trisomy 12 is the most common whole-chromosome abnormality in human pluripotent stem cells. Conventionally, this acquired aneuploidy is ascribed to a rare single-cell event followed by selective growth advantage. Instead, we show that trisomy 12 emerges simultaneously in a very high percentage of cells in critical transition passages. Mis-segregation and incorporation of chromosome 12 into […]

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 […]

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 […]

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 […]

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.

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 […]
