Scientists create realistic brain-wide connection maps through digital modeling
EPFL researchers have developed a powerful method to generate brain-wide, biologically realistic wiring maps of the mouse brain. Their approach bridges experimental data with mathematical and computational modeling to simulate how neurons connect across the entire brain.
The study is published in the journal Nature Communications.
One of neuroscienceâs greatest challenges is understanding how the brain is wired. Even with modern imaging tools, it has been a challenge to create detailed maps that show how the brainâs billions of cells (neurons) connect, not just with their local âneighborsâ but also to other, more distant cells in the brain.
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, spintronicsâusing both electron charge and spinâoffers a strong alternative to traditional devices. Magnetic tunnel junctions (MTJs), a key spintronics technology, are already used in data storage 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 organic light-emitting diodes (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.
âHeavyâ 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 âheavy fermionsââelectrons with greatly increased effective massâthat 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 companyâs 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 monthâs 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 didnât 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 monthâs 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.
