The article reframes dams as basin governance platforms through three interconnected pathways: engineering safety as the baseline, addressing sedimentation and structural risks; system operations as the core, shifting from single-purpose management to multiobjective coordination across safety, ecology, and public benefits; and digital-intelligent governance as the frontier, institutionalizing transparent and anticipatory decision-making. Drawing on China's experience with approximately 95,000 reservoirs, the authors demonstrate how this platform model can enhance resilience, ecological integrity, and public accountability. The framework offers transferable principles for global hydraulic infrastructure governance, contingent upon enabling institutional, financial, and data conditions.

A novel EMS-induced barley male-sterile mutant (N13401) was identified and characterized, and it shows defective pollen starch accumulation. The male sterility gene msg_N13401 was fine-mapped to a 576.9 kb region on chromosome 2H using a wild-cultivated barley cross to overcome the low polymorphism of cultivated barley.

Researchers from Tohoku University have developed a new kind of filter that overcomes a long-standing challenge,  creating a special material that makes separating CO2 from other gases both fast and highly accurate.

Photochromic materials, which change color reversibly under light, are essential for applications like smart lenses and optical storage. However, conventional photochromism, controlled solely by light, faces limitations in complex, real-world environments where precise, multi-factor control is required. The ability to modulate a material's response not just by light, but also by pH, electricity, or force, is the key to unlocking its next generation of applications. This necessitates a comprehensive understanding and systematic classification of these emerging "multigated" systems, which is the very gap our review aims to fill.

Researchers from The University of Osaka discovered a mechanism that greatly improves the efficiency of endothermic singlet exciton fission. By combining singlet-fission molecules with quantum dots, the team created hybridized electronic states at the material interface that act as intermediate energy pathways. This allows one absorbed photon to generate two excited states with high efficiency, potentially allowing solar technologies to exceed current efficiency limits.

Oxygen-dependent electrodynamic therapy is hindered by electron–hole recombination and hypoxia. This study provides a heterojunction-induced Jahn–Teller distortion-enhanced spin-engineering Fe₃O₄–Ag₂S nanoplatform to address these limitations. The large interfacial lattice mismatch induces previously unrecognized Jahn–Teller distortions on high-spin Fe sites, modifying d-orbital splitting and enhancing spin-polarized catalytic activity. This lattice–spin–carrier coupling synergistically amplifies catalase-, peroxidase-, and glutathioneox-like pathways. Under near-infrared irradiation, the photothermal effect of Fe₃O₄ activates the thermoelectric response of Ag₂S and drives continuous hot-carrier injection. Thermoelectric fields drive hot holes to boost catalase activity through Jahn–Teller effect-enhanced spin catalysis sites and drive hot electrons to convert O₂  to cytotoxic O₂^.− and ¹O₂ under the Jahn–Teller distortion, promoting and forming a self-amplifying catalytic loop. Fine structure characterization and density functional theory calculations collectively verify strain-driven Fe–O bond differentiation and spin-state reconfiguration. The heterojunction achieves potent thermoelectric–enzyme co-catalysis with 95% tumor inhibition under near-infrared irradiation and supports dual-mode imaging. This work establishes a framework for designing high-performance photothermal–thermoelectric catalysts through crystal field/spin-state modulation in p–n heterojunctions, synergistically boosting multi-enzyme activity and catalytic efficiency for hypoxia-resistant therapy.

In a major legislative move, China has adopted its first comprehensive Ecological and Environmental Code (EEC), a unified legal framework designed to address the interconnected global crises of climate change, biodiversity loss, and pollution. A commentary in the journal Carbon Research analyzes the significance of this new code, which takes effect on August 15, 2026. Authored by Jin Ma, Xiaoli Zhao, and Fengchang Wu from the Chinese Research Academy of Environmental Sciences, the piece outlines how the EEC provides a systematic legal solution for sustainable development and offers a new model for global environmental governance.

For decades, China’s environmental laws were fragmented across numerous statutes and regulations, a common challenge for many nations. The new EEC addresses this by systematically integrating more than 30 national laws and over 1,000 local regulatory documents into a single, coherent system. This “moderate codification” approach balances legal stability with the flexibility needed to address new environmental challenges, moving governance from passive, end-of-pipe remediation to proactive source prevention and control.
