Coalescence characteristics of free-living and particle-attached bacteria in a cascade river-reservoir system: A case study of the Jinsha River.

Microbial coalescence plays a crucial role in shaping aquatic ecosystems by facilitating the merging of neighboring microbial communities, thereby influencing ecosystem structure. Although this phenomenon is commonly observed in natural environments, comprehensive quantitative comparative studies on different lifestyle bacteria involved in this process are still lacking. The study focuses on 16S rRNA Amplicon Sequence Variants (ASVs) at the Jinsha River hydropower stations (Wudongde [WDD], Baihetan [BHT], Xiluodu [XLD], Xiangjiaba [XJB]), specifically examining free-living (FL) and particle-attached (PA) bacteria.

Visible-light-switchable Molecular Glues for Reversible Control of Protein Function.

Chemically induced dimerization/proximity (CID/CIP) systems controlled by chemical dimerizers (also known as molecular glues) provide valuable means for understanding and manipulating complex, dynamic biological systems. In this study, we present the development of versatile chemo-optogenetic systems utilizing azobenzene-based photoswitchable molecular glues (sMGs) for reversible protein dimerization controlled by visible light. These systems allow multiple cycles of light-induced dimerization, overcoming the limitations of irreversible photolysis in previous systems.

Ultrafast Laser-Induced Spin Dynamics in All-Semiconductor Ferromagnetic CrSBr-Phosphorene Heterostructures.

Ultrashort laser pulses are extensively used for efficient manipulation of interfacial spin injection in two-dimensional van der Waals (vdW) heterostructures. However, physical processes accompanying the photoinduced spin transfer dynamics on the all-semiconductor ferromagnetic vdW heterostructure remain largely unexplored. Here, we present a computational investigation of the femtosecond laser pulse induced purely electron-mediated spin transfer dynamics at a time scale of less than 50 fs in a vdW heterostructure.

Modulating Perovskite Surface Energetics Through Tuneable Ferrocene Interlayers for High-Performance Perovskite Solar Cells.

Achieving rational control over chemical and energetic properties at the perovskite/electron transport layer (ETL) interface is crucial for realizing highly efficient and stable next-generation inverted perovskite solar cells (PSCs). To address this, we developed multifunctional ferrocene (Fc)-based interlayers engineered to exhibit adjustable passivating and electrochemical characteristics. These interlayers are designed to minimize non-radiative recombination and, to modulate the work function (WF) and uniformity of the perovskite surface, thereby enhancing device performance.

A Review of the Prospera Spinal Cord Stimulation System with Multiphase Stimulation and Proactive Care.

Purpose Of Review: The purpose of this review is to describe the development and key features of the Prospera™ Spinal Cord Stimulation (SCS) System, as well as the clinical evidence supporting its use. Prospera delivers therapy using a proprietary multiphase stimulation paradigm and is the first SCS system to offer proactive care through automatic, objective, daily, remote device monitoring and remote programming capabilities.

Recent Findings: Results from the recently published BENEFIT-02 trial support the short-term safety and efficacy of multiphase stimulation in patients with chronic pain.
