Concentration and composition of nanoparticles and colloidal particles in a mine-waste contaminated river

Environmental context. Metals in filtered stream water are assumed to primarily be ions or bound to organic matter, but likely also consist of submicron particles. We found that submicron particles were abundant in a mine-waste contaminated stream, containing iron and manganese w...

Clickable Turn-On Nanoparticles for Target-Specific Intracellular Activation

Abstract Precise visualization of nanoparticles (NPs) at the subcellular level is crucial for targeted drug delivery. However, NPs functionalized with permanently fluorescent probes are challenging to detect when only a small fraction reaches the target compartment, as weak fluor...

Halogenostannates of Glycine and Its Derivatives

Abstract Five new halogenostannates of amino acids glycine (Gly), sarcosine (Sar), dimethylglycine (DMG), and betaine (Bet) were synthesized and characterized by structural analysis, infrared and Raman spectroscopy, diffuse reflectance spectroscopy, and photoluminescence. The com...

“In our village of Werbiwzi there lived about 150 Ukrainian families, among them four Jewish ones”. Alexander Granach’s Memories of His Childhood in Eastern Galicia

This article examines Alexander Granach’s autobiographical novel Da geht ein Mensch as a source for Jewish–non-Jewish relations in the Eastern Galician village of Verbivtsi around 1900. Reading Granach’s childhood memories microhistorically and source-critically, it reconstructs...

A short note on differential equations and on Geometry

A short note on differential equations. We add some lines of interest about Some topics in Geometry.

A Nontoxin Aminopyrimidine Probe for Near State-Independent NaV1.7 Inhibition

Abstract The voltage-gated sodium channel NaV1.7 is among the most compelling genetically validated pain targets; however, advanced small-molecule inhibitors, including voltage-sensing domain IV (VSD4)-directed series, have not yet achieved robust clinical efficacy, potentially r...

Short Communication on Email Management Systems

We present the opportunity to Manage Emails with More in-depth Computing Systems. Many options and examples are of interest.

Adaptive Precision Nutrition: Integrating Dynamic Phenotyping, Multi-Omics, Artificial Intelligence, and the Allostatic Viability Principle

Precision nutrition increasingly combines functional foods, multi-omics, digital phenotyping, and artificial intelligence, yet the incremental decision value of additional data layers remains uncertain. This critical narrative review and hypothesis-generating conceptual proposal...

Short Communication on Objects Found on Road

We have found some Objects on Road in Montreal City. Some Remarks are made.

Long-term Effects of Schedule Change: Examining Work Stressors, Performance, and Change Process Factors in a Compressed Work Schedule Over Time

Research on long-term outcomes of implementing compressed work schedules in organizations remains scarce and lacks a systematic analysis of how workers’ expectations and perceptions affect change outcomes. To explore short- and long-term outcomes of implementing a compressed work...

Teacher beliefs about climate action teaching: Exploring variation across instructional phases and types of action

Abstact Climate change education requires fostering students' skills in making informed decisions on climate-related actions. Thus, teacher education must equip teachers for such “climate action teaching” and may build on investigating teacher beliefs. Using the Theory of Planned...

A validation framework for translating ethnomicrobiology into microbiome-enabled desert restoration

Microbiome-based dryland restoration is promising but weakly validated. We develop ethnomicrobiology, the study of how human communities manage microbial processes, as a discovery-and-validation framework. A structured evidence map of 42 systems shows food fermentation is most ma...

Wind conditions shape co-migration fidelity in trans-Saharan birds at a Mediterranean stopover site

Abstract Weather is a key driver of bird migration, particularly near ecological barriers, where migratory species often converge before crossing. While its effects on individual timing are well documented, how weather reshapes the temporal assemblage of migratory bird communitie...

Social relationships promote access to food and information in wild jackdaws

Abstract Many animals form differentiated social relationships that can influence fitness, but the mechanisms behind these benefits are often unclear. How does the presence of social partners during foraging enhance access to food or information? Might individuals also incur shor...

An overview of international reference values for vitamin E intake – similarities and differences in derivation

Purpose The scientific knowledge for the essential fat-soluble vitamin E (VitE) remains inconclusive. There is still a lack of valid status parameters and deficiency symptoms for insufficient intake. Therefore, the derivation of a dietary reference value (DRV) for VitE is challen...

Integrative characterization of host–microbiome-diet axes during early-life development of the murine gut

Abstract Background Early-life development of the gut microbiome plays a critical role in shaping host physiology. However, a comprehensive understanding of how diet, microbial community assembly, functional capacity, and host intestinal maturation axes evolve and coordinate over...

Transitional High-Al to Intermediate-Cr Podiform Chromitites from Wadi Zikt (Khor Fakkan Block, United Arab Emirates): Evidence for Reactive Melt Percolation during Nascent Forearc Evolution

Abstract Podiform chromitites at Wadi Zikt in the Khor Fakkan Block of the United Arab Emirates constitute a previously undescribed occurrence within the mantle section of the Semail ophiolite. We combine field relations, electron-probe microanalysis, in situ LA–ICP–MS mineral an...

Registering A Company [Some Countries of Interest]

We are investigating how to register a company. Many options and countries are of interest (some examples are given).

Mask‐Free Electro‐Addressable Localization of GOx@ZIF‐8 on Prussian Blue Microelectrodes for Glucose Biosensing

Precisely integrating MOF powders into patterned electrochemical devices remains a processing challenge, as conventional methods often require masks, manual alignment, or poorly scalable steps and can lead to non-selective deposition and inefficient material use. While electropho...

Biological interaction fingerprints improve prediction of drug-induced steatosis

Abstract Drug-induced liver injury (DILI) is a major safety concern in drug development, with steatosis constituting a relevant toxicological phenotype within DILI. Current in vitro assays typically rely on lipid accumulation measurements in hepatocyte models, capturing only sele...
