Harnessing agro-waste for the high-efficiency removal of methylene blue using ball-milled magnetic Fe3O4@pistachio shell composites: From waste to resource
By Tamer S. Saleh, Mohamed N. Gomaa, Abdullah Akhdhar, Abdullah S. Al‐Bogami, Waleed A. El-Said — 2025-11-25
Researchers created a low-cost, magnetically separable adsorbent from pistachio shells and Fe3O4 nanoparticles that removed up to 95% of methylene blue dye under optimized conditions. The 20% Fe3O4 composite balanced capacity and accessibility of active sites, showed strong selectivity for cationic dyes, and retained over 93% performance after five reuse cycles. It’s a practical, circular-economy approach to cleaning industrial wastewater with easy recovery and regeneration.
Systematic transformation of urban cold chain networks: From cross-regional dependencies to sustainable local excellence
By Kewei Wang, Kekun Fan, Yuhong Chen — 2025-11-25
This study proposes a hierarchical optimization framework that reconfigures cold chain logistics from long-haul dependence to local, integrated networks. In a real-world case across 35 stores, the approach cut both costs and carbon emissions by 44.1% while boosting product freshness by 21.9%, introducing new metrics to quantify true system transformation. The takeaway: redesigning the network itself can resolve the usual cost–carbon trade-offs rather than merely balancing them.
Huayan Robotics to Showcase Advanced Collaborative Robots at iREX 2025 in Tokyo
By GlobeNewswire — 2025-11-25
Huayan Robotics is debuting heavy-payload and high-speed cobots at iREX 2025, including the S50 robot (50 kg payload, 2,000 mm reach) and a faster Elfin cobot for rapid loading, sorting, and palletizing. The company will also demo intelligent welding with drag-teaching and real-time seam tracking, plus a high-precision vision inspection system co-developed with KEYENCE. It’s a snapshot of how collaborative robotics is scaling precision, speed, and flexibility for more sustainable, efficient manufacturing.
FUSE token regains momentum after SEC issues no-action letter to the Solana DePIN project
By Charles Thuo — 2025-11-25
The SEC granted a conditional no-action letter to Fuse, a Solana-based DePIN project, signaling rare regulatory clarity for a utility-focused token tied to real-world energy participation. Designed as a consumptive asset rather than a speculative instrument, FUSE rewards activities like supporting distributed infrastructure or using EV chargers and can be redeemed for energy-related benefits. The move offers a potential blueprint for DePIN projects seeking compliant token models while boosting investor confidence.
This robot is edible, including the battery
By Nicole Dominikowski — 2025-11-25
EPFL researchers built a fully edible soft robot powered by an acid–base reaction between citric acid and baking soda, producing CO₂ to actuate movement—no plastics or metals required. The concept opens doors for safe, biodegradable robotics in applications like wildlife vaccination and ingestible devices. It’s an intriguing step toward sustainable, single-use robots that minimize environmental impact while expanding how and where robotics can operate.
Validation and evaluation of a tablet-based dietary record app for adults aged 70 and above
By Jette Hinrichsen, Vincent Quinten, Rebecca Diekmann — 2025-11-25
In a study of adults 70+, the NuMob-e-App showed good relative validity versus 24-hour recalls for energy, carbohydrates, and protein, with the strongest agreement for protein and beverages. While results trended toward slight underestimation overall, the app’s usability and real-time feedback make it a promising tool for preventive dietary self-monitoring. For stretched healthcare systems, this points to scalable, senior-friendly nutrition tracking that can support independence and early intervention.
