Agricultural and forestry biomass wastes, often discarded or burned without adequate management, lead to significant environmental harm. However, cellulose nanocrystals (CNCs), derived from such biomass, have emerged as highly promising materials due to their unique properties, including high tensile strength, large surface area, biocompatibility, and renewability. This review provides a detailed analysis of the lignocellulosic composition, as well as the elemental and proximate analysis of different biomass sources. These assessments help determine the yield and characteristics of CNCs. Detailed discussion of CNC synthesis methods -ranging from biomass pretreatment to hydrolysis techniques such as acid, mineral, solid acid, ionic liquid, and enzymatic methods-are provided. The key physical, chemical, and thermal properties of CNCs are also highlighted, particularly in relation to their industrial applications. Recommendations for future research emphasize the need to optimize CNC synthesis processes, identify suitable biomass feedstocks, and explore new industrial applications.

Background: As information and communication technologies and artificial intelligence (AI) become deeply integrated into daily life, the focus on users' digital well-being has grown across academic and industrial fields. However, fragmented perspectives and approaches to digital well-being in AI-powered systems hinder a holistic understanding, leaving researchers and practitioners struggling to design truly human-centered AI systems.
Objective: This paper aims to address the fragmentation by synthesizing diverse perspectives and approaches to digital well-being through a systematic literature review.

Street-level environments play a vital role in children's development by promoting their physical activity, cognitive growth, and overall development. This study systematically reviews the measurement tools available to assess street environments according to children's needs. This systematic review was conducted according to the PRISMA-COSMIN guidelines.

Probiotics are live beneficial microorganisms that confer health benefits to the host when administered in adequate amounts, have gained considerable scientific and commercial interest for their ability to support gut health, strengthen immunity, and reduce disease risk. This review traces the genesis of probiotic science from its origins in traditional fermented foods to contemporary clinical applications, offering a conceptual understanding of its evolution. A clear distinction is drawn between endogenous probiotics, naturally resident in the human microbiome, and exogenous probiotics, introduced via dietary supplements and functional foods.

The US healthcare system is characterized by a persistent deadlock, where high costs, low efficiency, and inequity resist fundamental reform. This stalemate is rooted in deep ideological divides, political polarization, a fragmented fiscal structure, and the power of entrenched interest groups. This article analyzes how recent trade protectionist policies, specifically tariffs on pharmaceuticals and their inputs, intersect with this domestic gridlock.

Background: The parasitoid Chelonus bifoveolatus is a promising biocontrol agent against the invasive fall armyworm (FAW) Spodoptera frugiperda, but its practical application hinges on cost-effective mass rearing. This study compares the biological performance and production economics of Ch. bifoveolatus reared on two factitious hosts (Corcyra cephalonica and Spodoptera litura) under controlled laboratory conditions.
