Interface-controlled antiferromagnetic tunnel junctions offer new path for next-gen spintronics

A research team led by Prof. Shao Dingfu at the Institute of Solid State Physics, the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, has unveiled a new mechanism for achieving strong spin polarization using antiferromagnetic metal interfaces.

Their findings, published in Newton recently, propose a third prototype of antiferromagnetic tunnel junction (AFMTJ), paving the way for faster and denser spintronic devices.

As electronics demand smaller size, higher speed, and lower energy use, spintronics—using both electron charge and spin—offers a strong alternative to traditional devices. Magnetic tunnel junctions (MTJs), a key spintronics technology, are already used in but face limits due to slow response speeds and unwanted magnetic fields from their ferromagnetic parts.

Optoelectronics research could bring holograms to your smartphone and closer to everyday use

New research from the University of St Andrews paves the way for holographic technology, with the potential to transform smart devices, communication, gaming and entertainment.

In a study published in Light: Science & Applications, researchers from the School of Physics and Astronomy created a new optoelectronic device from the combined use of holographic metasurfaces (HMs) and (OLEDs).

Until now, holograms have been created using lasers. However, researchers have found that using OLEDs and HMs gives a simpler and more compact approach that is potentially cheaper and easier to apply, overcoming the main barriers to hologram technology being used more widely.

“Heavy” Electrons Hold the Key to a New Type of Quantum Computer

Discovery of Planckian time limit offers new opportunities for quantum technologies. A collaborative team of researchers in Japan has identified “heavy fermions”—electrons with greatly increased effective mass—that display quantum entanglement controlled by Planckian time, the fundamental unit of

Windows 11 KB5064081 update clears up CPU usage metrics in Task Manager

Microsoft has released the KB5064081 preview cumulative update for Windows 11 24H2, which includes thirty-six new features or changes, with many gradually rolling out. These updates include new Recall features and a new way of displaying CPU usage in Task Manager.

The KB5064081 update is part of the company’s optional non-security preview update schedule, which releases updates at the end of each month to test new fixes and features coming to the next month’s Patch Tuesday.

Unlike regular Patch Tuesday cumulative updates, monthly non-security preview updates do not include security updates and are optional.

Microsoft says recent Windows update didn’t kill your SSD

Microsoft has found no link between the August 2025 KB5063878 security update and customer reports of failure and data corruption issues affecting solid-state drives (SSDs) and hard disk drives (HDDs).

Redmond first told BleepingComputer last week that it is aware of users reporting SSD failures after installing this month’s Windows 11 24H2 security update.

In a subsequent service alert seen by BleepingComputer, Redmond said that it was unable to reproduce the issue on up-to-date systems and began collecting user reports with additional details from those affected.

A Review of Light-Emitting Diodes and Ultraviolet Light-Emitting Diodes and Their Applications

This paper presents an extensive literature review on Light-Emitting Diode (LED) fundamentals and discusses the historical development of LEDs, focusing on the material selection, design employed, and modifications used in increasing the light output. It traces the evolutionary trajectory of the efficiency enhancement of ultraviolet (UV), blue, green, and red LEDs. It rigorously examines the diverse applications of LEDs, spanning from solid-state lighting to cutting-edge display technology, and their emerging role in microbial deactivation. A detailed overview of current trends and prospects in lighting and display technology is presented. Using the literature, this review offers valuable insights into the application of UV LEDs for microbial and potential viral disinfection.

Tianjin trials brain-computer interface for neurocritical care

China initiated its first multi-center clinical trial for brain-computer interface technology in neurocritical care on Sunday, marking a significant expansion of BCI applications beyond the rehabilitation of motor and cognitive functions.

The trial, launched in Tianjin, aims to explore new therapeutic approaches for severe neurological conditions.

Led by the Haihe Laboratory of Brain-Computer Interaction and Human-Machine Integration at Tianjin University and Tianjin Huanhu Hospital, the project brings together leading medical institutions from Beijing, Tianjin, Henan province, and other regions.

“This initiative will pave the way for broader medical applications, offering Chinese technologies, standards, and protocols for precise management of neurocritical conditions,” said Liu Xiuyun, deputy director of the Haihe Laboratory.

Engineers send quantum signals with standard Internet Protocol

In a first-of-its-kind experiment, engineers at the University of Pennsylvania brought quantum networking out of the lab and onto commercial fiber-optic cables using the same Internet Protocol (IP) that powers today’s web.

Reported in Science, the work shows that fragile quantum signals can run on the same infrastructure that carries everyday online traffic. The team tested their approach on Verizon’s campus fiber-optic network.

The Penn team’s tiny “Q-chip” coordinates quantum and classical data and, crucially, speaks the same language as the modern web. That approach could pave the way for a future “quantum internet,” which scientists believe may one day be as transformative as the dawn of the online era.
