Proteins with exposed arginine can selectively accumulate even on protein-resistant coatings, as reported by researchers from Science Tokyo. Through an in-depth analysis of which and how proteins adhere to various anti-fouling surfaces, the team found arginine disrupts the protective water layer that normally blocks adsorption. Their results will help scientists develop safer and more effective biocompatible materials for medical devices, such as stents and advanced biosensors.

A new artificial intelligence (AI)-based system shows how natural damage to traffic signs can mislead deep neural network (DNN)-based vision systems. The framework, AdvWT, uses a generative model to learn realistic damage patterns and then optimize them to trigger misclassification. Tests across multiple AI architectures showed strong attack success, transferability and physical-world robustness. The approach can identify vulnerabilities and improve AI generalization to real-world damage.

Volatile resistive switching in electron systems is crucial for developing next-generation electronics. However, its underlying mechanism remains underexplored. In a new study, researchers explore the effect of Joule heating on resistive switching in a bulk organic conductor with a sharp metal-insulator transition (MIT) and weak heat dissipation. The study offers crucial insights for understanding the intermediate resistance state in bulk crystals with MIT, offering a pathway toward developing durable and efficient resistive switching technologies.

Controlling Mpox may require more than a single intervention. Researchers from Hasanuddin University developed a mathematical model to examine how vaccination, treatment, quarantine, and educational campaigns could be combined to mitigate Mpox transmission. The full-control strategy reduced simulated infections by 97.85% compared with no intervention and was the most cost-effective among the strategies tested. These findings also underscore the importance of considering animal reservoirs to support long-term management of Mpox.

Researchers have developed a wide-field Fourier transform hyperspectral imaging system that captures electrochemical reactions on hundreds of individual nanoparticles simultaneously. By integrating a common-path interferometer with a fast 2D camera, the method provides real-time spectral evolution during electrodeposition of palladium and cadmium sulfide on gold nanoparticles. Statistical analysis reveals distinct deposition behaviors on nanospheres versus nanorods—insights that would require thousands of tedious single-particle measurements using conventional approaches.

Researchers have developed a compact, built-in neutron analyzer for on-site measurement of uranium loading and element changes in wet ion-exchange resins. The 80 kg system combines prompt fission-neutron counting with prompt-gamma spectroscopy. Laboratory tests yielded a 0.129 g/L uranium detection limit in 60 s, while a field campaign at a commercial in-situ recovery mine followed adsorption, elution, transformation and a second adsorption cycle.

Targeted drug delivery directly to the liver has unlocked major breakthroughs across medicine, but constructing the chemical key to enter liver cells remains complex and costly. Researchers have now introduced a nature-inspired, mobile delivery platform utilizing polyrotaxanes—supramolecular thread-like polymers where ring-shaped cyclodextrin molecules can freely rotate and slide along a central axle chain, effectively bypassing traditional synthetic bottlenecks.

Ammonia is essential for fertilizers and is emerging as a zero‑carbon energy carrier, but its industrial production via the Haber‑Bosch process is energy‑intensive and emits large amounts of CO₂. Meanwhile, nitrate pollution from agriculture and industry has contaminated groundwater worldwide, threatening ecosystems and human health. Electrocatalytic nitrate reduction to ammonia (NO₃RR) offers an elegant solution: using renewable electricity to convert nitrate waste into valuable ammonia.
