This research explores a new wireless implantable device designed to improve photodynamic therapy (PDT) for cancer treatment, particularly bladder cancer. By delivering light directly inside the body without wires, the system helps overcome the challenge of limited light penetration in traditional PDT. The study shows that the device can successfully generate the key molecules needed to destroy cancer cells, offering a promising step toward more precise, less invasive treatments in the future. 

Adding iron to the ocean can cause plankton to absorb more CO2 from the atmosphere. However, the effect depends on where in the world the method is used, and it can have far-reaching consequences for marine ecosystems and food chains, according to a new study in Nature.

As consumers increasingly favor environmentally responsible businesses, companies are under growing pressure to turn sustainability into a competitive advantage. A new study shows that environmental responsibility improves financial performance indirectly by increasing sales, identifying a key mechanism that has received little attention. The effect was strongest among large Chaebol firms and became more pronounced after the COVID-19 pandemic, highlighting the growing influence of green consumerism on business success. 

A simple flame-synthesis method can produce highly active catalysts for converting carbon dioxide into methane, as reported by researchers from Science Tokyo. The team used flame-assisted spray pyrolysis to manufacture nickel–cerium oxide catalysts with finer nanoparticles and more active sites than conventional methods. These catalysts achieved outstanding methanation performance while remaining suitable for large-scale production, offering a practical route toward carbon-neutral fuel technologies.

Steroid-induced osteonecrosis of the femoral head (SONFH) can prevent damaged bone from healing, often leading to joint collapse and disability. Researchers have now developed a coral-inspired, 3D-printed scaffold that reprograms immune cells to create a healing environment for bone repair. In vitro and in vivo studies showed that the scaffold promoted angiogenesis and bone regeneration, offering a promising strategy for overcoming the disease's underlying immune dysfunction and improving bone repair.

A physics-guided AI framework automatically optimizes 2.4 GHz CMOS low-noise amplifiers, reducing power consumption by 62% and improving linearity by 10.7 dB compared with an expert-designed baseline, while nearly doubling the rate of successful circuit simulations under foundry design constraints.

Eco-nanozymology, as an emerging interdisciplinary field, integrates nanotechnology with principles of enzymology to offer innovative strategies for energy conversion and environmental remediation. In contrast with conventional enzymology, eco-nanozymology enhances catalytic efficiency through the precise regulation of interfacial microstructures, electronic distributions, active site configurations, multienzyme cascade catalysis, and functionalized carrier engineering. By harnessing and amplifying natural ecological processes, eco-nanozymology enables effective modulation of energy flow and material cycling within ecosystems. This review focuses on recent advances in the application of eco-nanozymology across energy-related domains, including nitrogen fixation, carbon fixation, methane oxidation, hydrogen production, and energy conversion devices. It further provides an in-depth analysis of the recent progress in the efficient degradation of environmental pollutants and resource-oriented valorization of low-value biomass, such as lignin, agricultural residues, livestock manure, and microplastics. These studies highlight the pivotal role of eco-nanozymology in enhancing the efficiency of environmental management, accelerating the development of green energy technologies, and advancing carbon neutrality goals. The continued development of eco-nanozymology is expected to open new horizons for the deepening and expansion of nanozyme applications, offering green, environmentally friendly, and sustainable technological pathways to address global energy and environmental challenges.

Aqueous zinc-ion batteries are promising candidates for large-scale energy storage, yet their development is severely hindered by the interfacial instability of zinc anodes. Distinct from strategies employing pre-formed polymers, this work proposes an innovative monomer-induced in situ interface engineering strategy. By leveraging the preferential adsorption of acrylamide monomers on the Zn surface, a locally high-concentration region is created, which subsequently enables the in situ construction of a stable hydrated network interphase (HNI) triggered synergistically by Zn²⁺ and SO₄²⁻ during electrochemical cycling. The HNI precisely regulates Zn deposition via a triple synergistic mechanism: Lewis acid–base coordination (C = O···Zn²⁺) provides fixed nucleation sites; dynamically anchored SO₄²⁻ within the interphase forms negatively charged microregions that homogenize Zn²⁺ flux via Coulombic repulsion; and a dense hydrogen-bonding network effectively confines free water and suppresses side reactions. Benefiting from this multifunctional interphase, the Zn//Zn symmetric cell achieves an ultra-long cycling life of 8650 h (over 360 days) at 1 mA cm⁻² with excellent reproducibility, the Zn//Ti cell delivers a high average Coulombic efficiency of 99.71% at 5 mA cm⁻². The Zn//I₂ full cell retains 89.15% of its capacity after 12,000 cycles. This work provides a novel paradigm for interfacial construction toward high-performance zinc metal anodes.
