Virginia Tech researchers uncover a major loophole that allows corporate insiders to profit from bad news – before investors even know it.

Large language models (LLMs) are at the forefront of artificial intelligence (AI) and have been widely used for conversational interactions. However, assessing the personality of a given LLM remains a significant challenge. A research team at The Hong Kong Polytechnic University (PolyU) has developed an AI-driven assessment system, the Language Model Linguistic Personality Assessment (LMLPA), with capabilities to quantitatively measure the personality traits of LLMs through linguistic analysis.

Computer scientists at the University of Bath in the UK have reprogrammed a Roomba to perform four new tasks, showcasing how domestic robots can be harnessed during their regular downtime to make our lives easier. The team also proposes 100 additional ways these devices could be put to work when they would otherwise be inactive.

Carnegie Mellon University and Seoul National University (SNU) have announced a new collaboration to advance human-centered artificial intelligence research that prioritizes human well-being, accessibility and social responsibility.

The SNU-CMU Human-Centered AI Research Center (HCAI) aims to pioneer innovative AI solutions by combining interdisciplinary expertise in human-centered design. CMU and SNU have four joint research projects in the works for 2025. Each project brings together interdisciplinary teams of faculty and students from both institutions to advance ethical, people-centered AI. These projects explore key challenges in AI, including: How AI can support teamwork in programming; enhancing interactive problem-solving; detecting societal bias in vision-language models, and assisting older adults through socially intelligent agents.
