Shape-Shifting Antenna Takes Inspiration From 'The Expanse'

2024-12-16

Researchers at the Johns Hopkins Applied Physics Laboratory have developed a novel shape-shifting antenna inspired by the science fiction series, 'The Expanse'. Using 3D-printed shape-memory alloy, the antenna dynamically adapts its shape through heating and cooling to meet various communication needs. Effectively operating from 4-11 GHz, this innovative design holds promise for 6G wireless communication, addressing the challenge of requiring multiple antennas for multi-band operation. While slower than alternative technologies, it offers advantages in power efficiency and frequency range, especially in systems needing to integrate diverse antenna types for optimal performance.

AI and Sensor Networks Challenge Submarine Stealth

2024-12-16

The ability of submarines to remain undetected is facing a significant challenge due to rapid advancements in artificial intelligence, drones, and sensor networks. This article explores the AUKUS agreement between the US, UK, and Australia to build nuclear submarines and the modernization of China's naval submarine capabilities. Advanced sensor networks and AI algorithms can detect subtle traces of submarine activity, weakening the effectiveness of traditional submarine stealth technology. The article analyzes strategies to counter this challenge, including using noise to disrupt AI systems, deploying unmanned underwater vehicles, and employing strategic maneuvers. However, the AUKUS agreement also faces challenges such as high costs, uranium shortages, and the rapid development of China's submarine capabilities, making its future uncertain.

TSMC Unveils Nanosheet Transistors: A New Era for Chips

2024-12-15

TSMC showcased its next-generation N2 (2-nanometer) process at the IEEE International Electron Devices Meeting, marking its first foray into nanosheet transistors. Compared to its N3 process, N2 boasts up to a 15 percent speed increase, 30 percent better energy efficiency, and a 15 percent density boost. This new architecture offers greater flexibility, allowing for the creation of nanosheets with varying widths on the same chip, optimizing performance for different logic units, especially SRAM. Intel's research further validated the scalability of nanosheet architecture, demonstrating a high-performing 6-nanometer gate-length transistor, pointing the way towards continued advancement in chip technology and suggesting a potential extension of Moore's Law.

IBM's Executive Terminal: A Forgotten Chapter in Computing History

2024-12-13

A recently discovered 1968 videotape reveals IBM's previously unknown "Executive Terminal" system. Unlike Engelbart's "Mother of All Demos," which emphasized collaboration, this system created an information "war room" for top IBM executives. Executives used modified television sets to query information specialists, who then compiled information from various terminals and resources, presenting it visually to the executives. This showcases an alternative application of early computing technology within a hierarchical organization, contrasting sharply with the collaborative approach of the "Mother of All Demos." Together, they offer a fascinating glimpse into the early development of computing.

Fei-Fei Li: The Future of AI Vision Lies in 3D

2024-12-12

AI pioneer Fei-Fei Li delivered a keynote at NeurIPS, outlining her vision for computer vision. She argues that true visual intelligence requires moving beyond 2D image processing to 3D spatial understanding. Her startup, World Labs, is focused on giving AI 'spatial intelligence' – the ability to generate, reason within, and interact with 3D worlds. This unlocks creativity and productivity, impacting robotics, VR/AR, and more. Li stresses the need for substantial computing power and data, advocating for increased public sector investment in AI research.
