WASHINGTON, D.C. – The U.S. Naval Research Laboratory in conjunction with the Marine Corps Expeditionary Energy Office (E2O); the Operational Energy Capability Improvement Fund with the Office of the Assistant Secretary of Defense for Energy, Installations, and Environment; Aerostar; and Lockheed Martin conducted a technical demonstration held at Outlying Landing Field Seagle in Twentynine Palms, California, May 19-21, aiming to develop a technology for Navy vessels to "see over the horizon" using a combination of stratospheric high-altitude balloons (HABs) and unmanned aircraft, both included novel energy solutions.

A giant anomalous Hall effect (AHE) has been observed in a nonmagnetic material for the first time, as reported by researchers from Japan. This surprising result was achieved using high-quality Cd₃As₂ thin films, a Dirac semimetal, under an in-plane magnetic field. By modulating the material’s band structure, the team isolated the AHE and traced its origin to orbital magnetization rather than spin, challenging long-held assumptions in condensed matter physics.

Conventional wearable sweat sensors utilize hydrophobic ion-selective membranes (ISMs) and require tight contact and adhesives to achieve signal stability. However, this can lead to user discomfort and skin-related diseases, necessitating the development of non-contact alternatives. In a new study, inspired by the self-cleaning behavior of rose petals, researchers developed novel ISM-based sweat sensors that feature enhanced signal stability and performance, avoid skin contact, and are reusable, making them practical for daily use.
