In a Mn3Sn/W epitaxial bilayer, spin–orbit torque induces the coherent rotation of spins, which can couple to microwave currents. Unlike in ferromagnets, the resulting conversion of AC current to DC voltage remains robust at higher frequencies, which may facilitate the development of high-speed electronic devices.
The demonstration of the first fully functioning mechanical qubit offers a new platform for quantum information processing and could lead to ultraprecise gravity sensors.

Advanced Navigation and MBDA are creating a GPS-free drone navigation system using NILEQ’s neuromorphic sensors for terrain positioning.
Critics doubt that Emotiv’s earphone-style sensors can reliably track things like stress and attention—and some worry the technology will become yet another form of workplace surveillance.
Magnetic resonance imaging (MRI) is a fundamental tool in modern medicine, offering detailed views of internal organs and tissues. These large, tube-shaped MRI machines, commonly seen in hospitals, utilize powerful magnets to analyze and visualize the density of water and fat molecules within the body.
In addition to these molecules, other substances like metabolites can also be mapped, but their concentrations are often too low to produce clear images. To overcome this limitation, a technique known as hyperpolarization is employed to enhance the magnetic resonance signal of these substances, making them more visible during MRI scans.
Hyperpolarization involves preparing a substance outside the body in a state where its magnetization—key to creating MRI images—is near its maximum. This process can boost the signal by thousands of times compared to its natural state. Once hyperpolarized, the substance is injected into the patient and transported to the target organ or tissue. However, before this can happen, it is crucial to confirm that the substance is adequately hyperpolarized through rigorous quality control processes.
Scientists continue to monitor Mount Spurr, a volcano to the west of Anchorage and a huge chunk of the state’s population, after signs of unrest this spring, and again in the fall.
The Alaska Volcano Observatory raised its color code for Spurr to yellow, or “advisory” status, Oct. 16.
The observatory’s Scientist in Charge, Matt Haney, says that was after seismometers picked up an increased number of small earthquakes at the volcano and GPS sensors showed it was swelling up.
SAN DIEGO – U.S. Navy electronics experts are hiring two companies to develop enabling technologies to safeguard naval systems from the effects of high-altitude electromagnetic pulse (EMP).
Officials of the Naval Information Warfare Center Pacific in San Diego, announced estimated $12.5 million separate contracts Wednesday to Long Wave Inc. in Oklahoma City, Okla., and to Reliance Construction Co. in Cary, N.C., for high-altitude EMP hardening processes.
Effective thermal management is essential to ensuring the performance and lifespan of modern electronics. While polymers are widely used in electronic components, they inherently exhibit poor thermal conductivity, limiting their effectiveness in dissipating heat. To overcome this, researchers have been investigating the potential of integrating highly conductive fillers, such as liquid metals (LM), into polymers.
A new camera system is making it possible for humans to see colors in the way animals do, opening up a vivid new perspective on the natural world.
Led by researcher Vera Vasas, who has spent years studying animal vision, this innovative project is changing how we understand what animals actually see.
In collaboration with colleagues from the Hanley Color Lab at George Mason University, Vasas has developed a tool that lets us experience the world through the eyes of different species.
