SEOUL, December 26 (AJP) - Researchers have identified a critical security vulnerability in the "Mixture-of-Experts" architecture used by major artificial intelligence models such as Google Gemini. The study reveals that a single "malicious expert" hidden within an AI's internal structure can bypass safety filters, increasing the rate of harmful responses from zero to 80 percent. The Korea Advanced Institute of Science and Technology (KAIST) announced on De

SEOUL, December 23 (AJP) - Researchers have developed a new technology to grow human intestinal stem cells without using animal-derived materials, resolving a major safety hurdle for regenerative medicine. The method significantly improves the ability of these cells to move and repair damaged tissues, potentially accelerating treatments for intractable gastrointestinal diseases. The Korea Advanced Institute of Science and Technology (KAIST) announced on December 23 that a joint re

SEOUL, December 22 (AJP) - South Korea has finished the development of a next-generation bullet train designed to operate at 370 kilometers per hour, the transport ministry said Monday. The achievement positions South Korea as the world's second-fastest rail operator, after China, to operate commercial rail services at speeds exceeding 350 kilometers per hour. Finalized under a four-year national research and development program, the project focused on the EMU-370. This electr

SEOUL, December 22 (AJP) - Professor Yoo Seung-hwa and his research team at the Korea Advanced Institute of Science and Technology (KAIST) have developed an artificial intelligence system that can automatically manage factory machines and guide workers. The technology was created to help factories maintain production quality as experienced experts retire and more foreign workers enter the workforce, potentially creating language barriers on the factory floor.
