AI-powered intelligent 6G radio access technology significantly enhances wireless communication performance

Korea’s research community has reached an important milestone on the path toward next-generation mobile communications with the development of a technology platform that brings the 6G era closer. Researchers expect that AI-Native mobile networks, in which artificial intelligence autonomously controls and optimizes the communication system, could achieve transmission efficiencies up to 10 times higher than those of 5G.

Breakthroughs in AI-based wireless access ETRI has completed the development of AI-based wireless access technology (AI-RAN), a core foundational technology for the 6G era, and has achieved significant results in paving the way for the AI-based next-generation mobile communication era.

The biggest feature of this technology is that it has applied AI to wireless transmission, network control, and edge computing throughout the network to reliably handle large volumes of data even in ultra-dense network environments.

Harnessing nanoscale magnetic spins to overcome the limits of conventional electronics

Researchers at Kyushu University have shown that careful engineering of materials interfaces can unlock new applications for nanoscale magnetic spins, overcoming the limits of conventional electronics. Their findings, published in APL Materials, open up a promising path for tackling a key challenge in the field and ushering in a new era of next-generation information devices.

The study centers around magnetic skyrmions—swirling, nanoscale magnetic structures that behave like particles. Skyrmions possess three key features that make them useful as data carriers in information devices: nanoscale size for high capacity, compatibility with high-speed operations in the GHz range, and the ability to be moved around with very low electrical currents.

A skyrmion-based device could, in theory, surpass modern electronics in applications such as large-scale AI computing, Internet of Things (IoT), and other big data applications.

Engineers invent wireless transceiver that rivals fiber-optic speed

A new transceiver invented by electrical engineers at the University of California, Irvine boosts radio frequencies into 140-gigahertz territory, unlocking data speeds that rival those of physical fiber-optic cables and laying the groundwork for a transition to 6G and FutureG data transmission protocols.

To create the transceiver, researchers in UC Irvine’s Samueli School of Engineering devised a unique architecture that blends digital and analog processing. The result is a silicon chip system, comprising both a transmitter and a receiver, that’s capable of processing digital signals significantly faster and with much greater energy efficiency than previously available technologies.

The team from UC Irvine’s Nanoscale Communication Integrated Circuits Labs outline its work in two papers published this month in the IEEE Journal of Solid-State Circuits. In one, the engineers discuss the technology they call a “bits-to-antenna” transmitter, and in the second, they cover their “antenna-to-bits” receiver.

Too much entanglement? Quantum networks can suffer from ‘selfish routing,’ study shows

Quantum technologies, systems that process, transfer or store information leveraging quantum mechanical effects, could tackle some real-world problems faster and more effectively than their classical counterparts. In recent years, some engineers have been focusing their efforts on the development of quantum communication systems, which could eventually enable the creation of a “quantum internet” (i.e., an equivalent of the internet in which information is shared via quantum physical effects).

Networks of quantum devices are typically established leveraging quantum entanglement, a correlation that ensures that the state of one particle or system instantly relates to the state of another distant particle or system. A key assumption in the field of quantum science is that greater entanglement would be linked to more reliable communications.

Researchers at Northwestern University recently published a paper in Physical Review Letters that challenges this assumption, showing that, in some realistic scenarios, more entanglement can adversely impact the quality of communications. Their study could inform efforts aimed at building reliable quantum communication networks, potentially also contributing to the future design of a quantum internet.

Chinese military says it is developing over 10 quantum warfare weapons

China’s military says it is using quantum technology to gather high-value military intelligence from public cyberspace.

The People’s Liberation Army said more than 10 experimental quantum cyber warfare tools were “under development”, many of which were being “tested in front-line missions”, according to the official newspaper Science and Technology Daily.

The project is being led by a supercomputing laboratory at the National University of Defence Technology, according to the report, with a focus on cloud computing, artificial intelligence and quantum technology.

Video: Why ‘basic science’ is the foundation of innovation

At first glance, some scientific research can seem, well, impractical. When physicists began exploring the strange, subatomic world of quantum mechanics a century ago, they weren’t trying to build better medical tools or high-speed internet. They were simply curious about how the universe worked at its most fundamental level.

Yet without that “curiosity-driven” research—often called basic science—the modern world would look unrecognizable.

“Basic science drives the really big discoveries,” says Steve Kahn, UC Berkeley’s dean of mathematical and physical sciences. “Those paradigm changes are what really drive innovation.”

Sam Altman Cornered by Discovery: Intent & Emails in Elon’s OpenAI Lawsuit

Internet Gaming Disorder is affecting a significant portion of young adults

Researchers out of Spain and Italy report a globally pooled Internet Gaming Disorder prevalence of 6.1% among adults ages 18–35. Internet Gaming Disorder is considered a condition for further study in DSM-5-TR, with official classification in ICD-11.

Gaming problems often get viewed as an adolescent concern, while evidence indicates growing vulnerability in young adults. Late adolescents and young adults tend to show higher levels of depression, anxiety, and stress, along with lower self-esteem, compared to healthy regular gamers.

DSM-5-TR includes nine criteria for Internet Gaming Disorder, including preoccupation with gaming, withdrawal symptoms, tolerance, unsuccessful attempts to control gaming habits, loss of interest in previous hobbies, continued excessive gaming despite problems, deception about the extent of gaming, gaming used to escape negative mood, and jeopardizing relationships or opportunities. Diagnosis requires at least five of those nine criteria within 12 months.

ChatGPT found to reflect and intensify existing global social disparities

New research from the Oxford Internet Institute at the University of Oxford, and the University of Kentucky, finds that ChatGPT systematically favors wealthier, Western regions in response to questions ranging from “Where are people more beautiful?” to “Which country is safer?”—mirroring long-standing biases in the data they ingest.

The study, “The Silicon Gaze: A typology of biases and inequality in LLMs through the lens of place,” by Francisco W. Kerche, Professor Matthew Zook and Professor Mark Graham, published in Platforms and Society, analyzed over 20 million ChatGPT queries.
