Tiny nanolaser could cut computer energy use in half

Scientists have created an ultra-small nanolaser that could eventually allow microchips to transmit information with light instead of electricity, potentially making computers faster while cutting energy use roughly in half. Thousands of the lasers could fit on a single chip, opening possibilities for more efficient data centers, smartphones, and advanced medical sensors.

Bridging the information gap: AI-driven quality control for 5G multicast broadcasting

Cable television (CATV) remains a cornerstone of how national broadcasts and emergency information reach thousands of households. Unfortunately, many older apartment buildings were not built with fiber-optic wiring in mind, making retrofitting with the necessary CATV infrastructure too costly or impractical and leaving residents unable to access broadcast services.

Memristor chip breaks the capacity limit of brain-inspired associative memory

Researchers in the Department of Electrical and Computer Engineering of the Faculty of Engineering and the Centre for Advanced Semiconductors and Integrated Circuits (CASIC) at the University of Hong Kong (HKU) have made a breakthrough in brain-inspired computing. In collaboration with Hewlett Packard Labs, the team has developed a memristor chip that overcomes a long-standing …

Long AI conversations reveal misinformation vulnerabilities across seven leading chatbots

The results are in: Which AI model is the most fallible? Persuadable? Correctible? University of Arizona researchers assessed seven different generative AI large language models, or LLMs, for these three qualities during lengthy conversations. Their work, published in Nature’s Scientific Reports, reveals intrinsic limitations that might go undetected during one-off interactions.
