It's a simple law of physics: When electricity or fuel powers a machine, the machine gets hotter. Finding new ways to cool machines quickly and controllably can mean the difference between a functioning electrical grid and a blackout or a working data center and a widespread outage.

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.

What is patient privacy for? The Hippocratic Oath, thought to be one of the earliest and most widely known medical ethics texts in the world, reads: "Whatever I see or hear in the lives of my patients, whether in connection with my professional practice or not, which ought not to be spoken of outside, I will keep secret, as considering all such things to be private."

Elon Musk's AI tool Grok faced growing international backlash Monday for generating sexualized deepfakes of women and minors, with the European Union joining the condemnation and Britain warning of an investigation.

Le Xie, Professor of Electrical Engineering at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS), wants to know how we can modernize the electric grid to support rapid electrification and the growing demands of AI infrastructure. His research at SEAS focuses on the intersection of power systems, artificial intelligence, and decarbonization. We spoke to him about his work and the challenges facing the electric grid today. This interview has been edited for clarity and length.

Grok, the chatbot of Elon Musk's artificial intelligence company xAI, published sexualized images of children as its guardrails seem to have failed when it was prompted with vile user requests.

Optical computing has emerged as a powerful approach for high-speed and energy-efficient information processing. Diffractive optical networks, in particular, enable large-scale parallel computation through the use of passive structured phase masks and the propagation of light. However, one major challenge remains: systems trained in model-based simulations often fail to perform optimally in real experimental settings, where misalignments, noise, and model inaccuracies are difficult to capture.

Since 2021, Korean researchers have been providing a simple software development framework to users with relatively limited AI expertise in industrial fields such as factories, medical, and shipbuilding, providing them with a significant boost.

Until now, AI services based on large language models (LLMs) have mostly relied on expensive data center GPUs. This has resulted in high operational costs and created a significant barrier to entry for utilizing AI technology. A research team at KAIST has developed a technology that reduces reliance on expensive data center GPUs by utilizing affordable, everyday GPUs to provide AI services at a much lower cost.

Japanese tech investor SoftBank said Wednesday that its stake in OpenAI is now around 11% after completing the second stage of a $41-billion investment in the maker of ChatGPT.
