Compartmentalized Homeostasis Drives High Bamboo Forest Productivity under Nutrient Imbalance

Advanced Science, EarlyView.
This study reveals how Moso bamboo achieves high productivity despite nutrient‐poor soils. It employs a unique strategy, maintaining strict nutrient balance in its leaves while using woody tissues as flexible storage reservoirs. This compartmentalized mechanism buffers the plant from soil phosphorus limitation and microbial competition, resolving the ...

Accelerating Biosensor Discovery: A Computationally‐Driven Pipeline for Microplastics Monitoring

Advanced Intelligent Discovery, EarlyView.
A computationally guided pipeline unites molecular simulation, synthetic biology, electrochemical engineering, and machine learning to accelerate biosensor discovery. A Bacillus anthracis carbohydrate‐binding module is used to develop a high‐performance micro‐ and nanoplastics sensor with greatly reduced error and variability.

ZSF1 lean rats – How healthy are they?

Animal Models and Experimental Medicine, EarlyView.
This study aimed to examine the health status, specifically the physiology and myocardial, vascular, and skeletal muscle function of lean ZSF1 rats by comparing them to age‐ and sex‐matched Wistar rats. Compared to Wistar controls, ZSF1 lean rats exhibited lower body weight, but showed increased heart, and skeletal muscle mass.

Ungesättigte Phosphor‐Elektrophile zur Untersuchung von Protein‐Tyrosin‐Phosphatasen

Angewandte Chemie, EarlyView.
Negativ geladene Aryl‐Ethynyl‐Phosphonamid‐ und Phosphonsäuren werden als reaktionsarme Elektrophile für peptidbasierte Aktivitätssonden eingeführt, die eine selektive, zielspezifische Profilierung von Protein‐Tyrosin‐Phosphatasen ermöglichen. Die Sonden zeigen keine Off‐Target‐Cystein‐Reaktivität und binden in der globalen Proteomanalyse nur an die ...

Effect of Ramped Oxygen Flow During Magnetron Sputtering on the Structural, Optical, and Photoelectrochemical Properties of WO3‐x Thin Films

Advanced Physics Research, EarlyView.
A compositionally graded WO3‐x thin film was engineered through a controlled linear increase of oxygen flow during reactive magnetron sputtering. This deposition strategy yields a gradual transition from an oxygen‐deficient, conductive bottom layer to a more stoichiometric and crystalline surface layer, forming an intrinsic gradient homojunction.

Neuroanatomical diversity in Teleocichla with new volumetric and histological insights into the encephalon of Teleocichla monogramma Kullander 1988

The Anatomical Record, EarlyView.
Abstract Teleocichla comprises small cichlids that inhabit the rapid streams of Amazonian rivers; however, there has been limited research on their encephalon morphology. This study examined the neuroanatomy of four species, focusing on volumetric measurements of their encephalon subregions, and providing a histological description of the encephalon of
