Nanotube Links Enable Communication Between Social Amoebae
Social amoebae coordinate as individual cells form shifting, cooperative assemblies. New findings now suggest that this coordination is supported by more intimate physical exchange than...
Link Between Weight Changes and Cognitive Decline in Older Adults
In an era where global populations are aging, cognitive decline has become a public-health priority. Yet the factors that shape brain health in later life...
Photogenerated triplet nitrene enables gold-mediated nitrene transfer
A team of chemists has unveiled a light-driven way to move nitrogen fragments onto gold—an advance that could make nitrene-transfer chemistry faster, more selective, and...
Fractionated Proteomics Uncovers Protein Network Reducing Exercise-Induced Muscle Damage
Resistance training is celebrated for building strength, but it also triggers a cascade of molecular stress in skeletal muscle—damage that the body must quickly manage...
Rescuer Rotation Affects Neonatal Chest Compression Metrics, Simulation Study Finds
A new simulation study highlights a subtle but potentially consequential factor in neonatal resuscitation: the rotation of the rescuer during chest compressions. Published in Pediatric...
Standardizing Lung Ultrasound to Improve Neonatal Care Outcomes
A new study shines a spotlight on a simple but potentially transformative idea in neonatal intensive care: making lung ultrasound (LUS) use consistent across clinicians....
Alpha-synuclein Aggregates Differentially Alter Electrophysiology of SNpc and VTA Neurons
A team led by Del Popolo and colleagues reports that aggregated α-synuclein—an established driver of Parkinson’s disease pathology—does not affect dopamine neurons uniformly. Using acute...
Adaptive policies could boost Zambia nutrition security amid future climate shocks
Zambia is on the front line of climate volatility, and new research suggests that smart, adaptive policy could help protect nutrition—even when droughts, floods, and...
Study finds higher healthcare costs linked to inappropriate medication use in seniors
A new matched-cohort study tracking older adults has quantified a problem clinicians often flag but rarely measure at scale: the healthcare and financial consequences of...
Single-Plane Imaging Tracks Dynamic 3D Structures in Living Cells with Focus Feedback
A new protocol promises to make three-dimensional tracking in living cells far less punishing for both cells and microscopes. Instead of repeatedly acquiring full z-stacks—which...
Nanoneedle Arrays Enable Sequencing-Free Spatial Profiling of Fresh Tissue Regulation
A team of researchers has unveiled a sequencing-free, amplification-free strategy for mapping gene regulation directly in space, tackling key bottlenecks that have limited current spatial...
China Issues Consensus on Precision Testing and Molecular Diagnosis for Pancreatic Cancer
The Chinese Society of Clinical Oncology (CSCO) has issued an expert consensus that aims to standardize molecular testing in pancreatic ductal adenocarcinoma (PDAC), a disease...
Pediatrician Office Treatment for Childhood Obesity Proves Effective
Childhood obesity remains a stubborn public-health challenge in the United States, affecting roughly one in five children, yet specialized pediatric weight-management resources are still out...
Traditional food program cuts heart failure hospitalizations in Navajo Nation
PHILADELPHIA—A randomized clinical trial published in JAMA Internal Medicine reports that a culturally tailored meal program based on traditional Diné (Navajo) foods can meaningfully reduce...
