Advances in technology have led to the miniaturization of many mechanical, electronic, chemical and biomedical products, and with that, an evolution in the way these tiny components and parts are transported is necessary to follow. Transport systems, such as those based on conveyor belts, suffer from the challenge of friction, which drastically slows the speed and precision of small transport. Researchers from YOKOHAMA National University addressed this issue by developing an untethered levitation device capable of moving in all directions. The frictionless design allows for ultrafast, agile movement that can prove to be very valuable in machine assembly, biomedical and chemical applications via contactless transport.

Researchers published their results in Advanced Intelligent Systems in July 2025.

Not all blood vessels play equal roles in brain health. To uncover how the brain regulates its complex circulation, researchers built a detailed computer model of mouse brain vasculature. Focusing on transitional zone vessels—crucial links between arteries and capillaries—the model simulates how each segment adjusts like a tiny valve. It reveals how the brain stabilizes blood flow during pressure shifts or heightened activity, offering new insights into brain protection and potential breakthroughs in diagnosing stroke, Alzheimer’s, and traumatic brain injuries.

The development of efficient electrocatalysts for saline water oxidation (SWO) is imperative for advancing seawater splitting technology to produce green hydrogen. In this work, a NiFe-Co₂(OH)₃Cl material was developed as pre-electrocatalyst for both active and stable SWO. During catalysis, the hydroxyloride was converted to oxyhydroxide with 35.4% enlarged ECSA, leading to the enhanced intrinsic activity (300 mV@10 mA cm^-2, 49.9 mV decade^-1). Moreover, the electrolyte Cl^- would be incorporated to the catalyst lattice, thus improving the corrosion-resistance of the material, resulting in the high electrocatalytic stability for 100 h.

WASHINGTON, D.C. — The U.S. Naval Research Laboratory’s (NRL) Scientific Development Squadron (VXS) 1 is the U.S. Navy’s only research and development squadron; responsible for airborne scientific experimentation and advanced technology development connecting laboratory innovations to operational deployment.

Electroretinography (ERG) is an ophthalmic diagnostic method used to determine whether the retina is functioning normally. It is widely employed for diagnosing hereditary retinal diseases or assessing retinal function decline.

A team of Korean researchers has developed a next-generation wireless ophthalmic diagnostic technology that replaces the existing stationary, darkroom-based retinal testing method by incorporating an “ultrathin OLED” into a contact lens. This breakthrough is expected to have applications in diverse fields such as myopia treatment, ocular biosignal analysis, augmented-reality (AR) visual information delivery, and light-based neurostimulation.
