Tech Xplore / Space-grade perovskite solar cells can survive extreme temperature fluctuations
The Aydin Group at LMU Munich has unveiled a novel strategy for making perovskite solar cells more robust against extreme temperature fluctuations. To this end, the researchers led by Dr. Erkan Aydin, group leader at LMU's ...
Tech Xplore / New X-ray vision for electronics lets scientists monitor working chips remotely
A team of international researchers have developed a breakthrough way to observe what is happening inside electronic chips while they are operating—without touching them, taking them apart, or switching them off. The new ...
Tech Xplore / A better method for identifying overconfident large language models
Large language models (LLMs) can generate credible but inaccurate responses, so researchers have developed uncertainty quantification methods to check the reliability of predictions. One popular method involves submitting ...
Tech Xplore / LED method blocks ambient light to keep projection images sharp in bright environments
Projection mapping has the potential to create shared immersive experiences in exhibitions, commercial facilities, and public spaces. However, the technique is highly sensitive to ambient lighting, meaning that clear projected ...
Tech Xplore / Light becomes matter: Shadowless projection mapping makes images indistinguishable from print
Projection mapping is widely known as a lighting technique that overlays images onto buildings or objects to create visual effects. In fields such as extended reality (XR) and vision science, however, researchers have suggested ...
Tech Xplore / SoulMate LLM accelerator evolves according to the specific characteristics of the user
While large language models (LLMs) like ChatGPT are adept at answering countless questions, they often remain unaware of a user's minor habits or previous conversational contexts. This is why AI, despite being deeply integrated ...
Tech Xplore / Wearable thermoelectric technology uses thin films to generate electricity from body heat
Seoul National University College of Engineering has announced that a research team led by Prof. Jeonghun Kwak of the Department of Electrical and Computer Engineering, with co-first authors Dr. Juhyung Park and Dr. Sun Hong ...
Tech Xplore / 55% of U.S. teens have used AI to create sexualized images, survey finds
In a survey study of U.S. teens, more than half (55.3%) reported that they had created at least one image using nudification tools, which use generative artificial intelligence (GenAI) to show what an individual may look ...
Tech Xplore / Sheepdogs reveal a better way to guide robot swarms
Sheepdogs, bred to control large groups of sheep in open fields, have demonstrated their skills in competitions dating back to the 1870s. In these contests, a handler directs a trained dog with whistle signals to guide a ...
Tech Xplore / AI chatbots' tendency to always agree may reinforce delusions in vulnerable users
The integration of large language model-based AI chatbots into multiple facets of our everyday lives has opened us up to advantages that would have been considered impossible even a decade ago. The same development has, however, ...
Tech Xplore / Record efficiency achieved for perovskite-silicon triple-junction solar cells
Researchers from the Photovoltaics and Thin-Film Electronics Laboratory (PV-Lab) in EPFL's School of Engineering and CSEM have developed a new solar cell that combines exceptional voltage, high efficiency, and scalable manufacturing. ...
Tech Xplore / Top AI coding tools make mistakes one in four times, study shows
New research from the University of Waterloo shows that artificial intelligence (AI) still struggles with some basic software development tasks, raising questions about how reliably AI systems can assist developers. As Large ...
