After years of false starts, the future of augmented reality may depend not on chips or software, but on how light moves through glass.

To study consciousness comprehensively and rigorously, what kinds of data or information are relevant? Data/information for Materialism theories, which are subject to the scientific method, can be well defined. But what about non-Materialism theories?

Performance Improvements In UE5.7 Over UE5.4
A new video from MxBenchmarkPC demonstrates the performance gains in Unreal Engine 5.7 by comparing it side by side with Unreal Engine 5.4 using the recently released Venice tech demo by Scans Factory.
The test was conducted at 4K and 1440p with Nanite and hardware ray tracing with Lumen, using Ultra settings on an RTX 5,080 paired with an Intel Core i7-14700F.
“GPU performance is improved by up to 25% in UE5.7 (depending on a scene), and the 5.7 version is now better utilizing GPU resources, hence the GPU power draw is now higher,” commented MxBenchmarkPC. “UE5.7 offers a significant up to 35% CPU performance boost (depending on the scene) and more stable frametimes with less hitches across all scenes.”
Physicists push superconducting diodes to high temperatures
For the first time, researchers in China have demonstrated a high-temperature superconducting diode effect, which allows a supercurrent to flow in both directions. Published in Nature Physics, the team’s result could help address the noisy signals that pose a fundamental challenge in quantum computing.
A diode is a device that shows an asymmetric electrical response, allowing current to flow more easily in one direction than the other. Until recently, diode behavior had only been observed in conventional, non-superconducting electrical systems—but in 2020, a team of researchers in Japan became the first to demonstrate the diode effect in a superconductor. Ever since, this effect has gained increasing attention for its potential in practical quantum computing.
“However, most of the reported superconducting diodes work at low temperatures around 10 Kelvin, and often require an external magnetic field,” explains Ding Zhang at Tsinghua University and the Beijing Academy of Quantum Information Sciences, who led the research. “The diode efficiency is also low for many superconducting diodes.”
Cisco Warns of Active Attacks Exploiting Unpatched 0-Day in AsyncOS Email Security Appliances
Cisco has alerted users to a maximum-severity zero-day flaw in Cisco AsyncOS software that has been actively exploited by a China-nexus advanced persistent threat (APT) actor codenamed UAT-9686 in attacks targeting Cisco Secure Email Gateway and Cisco Secure Email and Web Manager.
The networking equipment major said it became aware of the intrusion campaign on December 10, 2025, and that it has singled out a “limited subset of appliances” with certain ports open to the internet. It’s currently not known how many customers are affected.
“This attack allows the threat actors to execute arbitrary commands with root privileges on the underlying operating system of an affected appliance,” Cisco said in an advisory. “The ongoing investigation has revealed evidence of a persistence mechanism planted by the threat actors to maintain a degree of control over compromised appliances.”
