Comparative Adsorption Mechanisms of Coconut-Shell and Corn-Stalk Biochars for Cd²⁺, Pb²⁺, and Zn²⁺ in Aqueous Solutions

This study demonstrates that while both coconut-shell and corn-stalk biochars effectively remove Cd²⁺, Pb²⁺, and Zn²⁺ through chemisorption and heterogeneous multilayer adsorption with a preference for Pb²⁺, the corn-stalk biochar exhibits superior maximum adsorption capacity due to its richer oxygenated functional groups and mineral components.

Institutional opening and regional entrepreneurial activity: Evidence from cross-border e-commerce comprehensive pilot zones in China

This study utilizes a staggered difference-in-differences approach to demonstrate that China's Cross-Border E-Commerce Comprehensive Pilot Zones significantly boost regional entrepreneurial activity by fostering digital talent agglomeration, alleviating fiscal pressure, and developing new digital infrastructure, with effects being more pronounced in eastern regions and among non-state-owned enterprises.

Lipid profile in chronic kidney disease patients before dialysis at University Hospital Center Yalgado OUEDRAOGO, Ouagadougou-Burkina Faso

This case-control study conducted at a hospital in Burkina Faso reveals that patients with chronic kidney disease prior to dialysis exhibit a significantly more atherogenic lipid profile, characterized by elevated LDL and non-HDL cholesterol, reduced HDL, and hypertriglyceridemia, with the severity of these abnormalities generally increasing alongside the stage of kidney disease.

Machine learning maps the “dark matter” of the global marine fish food web

By applying a positive-unlabeled machine-learning framework to integrate species traits, taxonomy, and environmental data, this study reconstructs a global probabilistic marine fish food web that reveals a vast, structured network of previously undocumented interactions, fundamentally shifting the understanding of marine trophic architecture from sparse to densely connected and suggesting that ecosystems are more resilient than empirical records indicate.

Measurement of transfer factor – TF of radioactive elements in the fast-growing plant culture Helianthus tuberosus L (sunchoke)

This study evaluates the transfer factors of radionuclides (Cs-137, Ra-226, and K-40) from soil to various parts of the fast-growing sunchoke plant (*Helianthus tuberosus* L.) in Vojvodina, revealing that while the plant accumulates these elements, it notably reconcentrates potassium-40 in all its parts, raising potential concerns for food safety and public exposure.

Statistical learning of bacterial growth in combinatorially constructed environments

By employing a full factorial design to map carbon source interactions across seven bacterial species, this study demonstrates that while individual nutrients can exhibit context-dependent negative effects due to global epistasis, bacterial growth in complex environments is predominantly driven by additive and pairwise effects, enabling accurate prediction and rational optimization of growth conditions through simple statistical models.
