Circuit Links Drive and Social Contact to Mate

Neural circuits orchestrate complex behaviors by integrating diverse internal states with external environmental cues. A groundbreaking study published in Nature in 2025 by Salay, Tsao, and Anderson illuminates a previously obscure neural pathway that governs mating behavior in male mice by combining sexual drive with direct social contact, revealing the delicate neurobiological choreography underlying reproductive […]

Allocation of resources among multiple daughter cells

Cell division commonly produces two daughter cells, but there are many exceptions where large cells produce multiple daughters. Multiple fission of some green algae and bacteria; cellularization during embryogenesis of plants and insects; and growth of Ichthyosporeans, Chytrids, and Apicomplexans all provide variations on this theme. In some yeast species, a large multinucleate mother cell […]

Nomograms Enhance Prognosis in ECMO for Septic Shock

In a groundbreaking study, researchers are advancing the field of critical care medicine with the introduction of innovative nomograms designed to predict outcomes for patients undergoing venoarterial extracorporeal membrane oxygenation (VA-ECMO) treatment for septic shock. Septic shock remains one of the most severe complications of infections, often leading to multiple organ failure and significant mortality […]

Submembrane liprin-α1 clusters spatially localize insulin granule fusion

Insulin granule fusion in pancreatic β cells localizes to where they contact the ECM of the islet capillaries. The mechanism(s) underpinning localization are unclear. Using glucose or high K+ stimulation or the global uncaging of Ca2+, we show granule fusion consistently focused to the β cell–ECM interface, suggesting a specific localization mechanism. We tested for […]

Aortic Valve Guides Umbilical Artery Catheter Placement

In the fast-evolving world of neonatal intensive care, the quest for safer, more efficient methods to monitor and treat our most fragile patients is relentless. A new study published in the Journal of Perinatology sheds light on a novel ultrasound-guided technique that may revolutionize the placement of umbilical artery catheters (UAC) in neonates. This method […]

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 […]

A tiny ocean worm just revealed a big secret about how eyes evolve

A research team from the University of Vienna and the Alfred Wegener Institute in Bremerhaven has uncovered how the eyes of adult marine bristleworms continue to increase in size throughout their entire lifespan. The work shows that this constant growth is powered by a ring of neural stem cells that resembles similar structures found in […]

Will Glacier Melt Lead to Increased Seismic Activity in Mountain Regions? – State of the Planet

A recent study from Earth and Planetary Science Letters is the first to directly link earthquakes to climate change-induced glacial melt. Scientists analyzed 15 years of seismic activity in the Grandes Jorasses—a peak that is part of the Mont Blanc massif between Italy and France—to better understand this association. This massif is one of the […]
