Tech Xplore / New benchmark tests AI memory for household robots
In-home assistive robots could clean and organize a home while the owner is away, but without enhanced memory capabilities, they could cause more problems than they solve. They could, for example, cause a major inconvenience ...
Tech Xplore / AI defeats top war game rivals using fewer practice games and on-the-fly planning
A new AI system that excels at challenging games with hidden information could someday help human decision-makers select strategies to outfox opponents in complicated situations like military maneuvers.
Tech Xplore / Quantum-inspired math could help AI recognize when it does not know the answer
Anyone who has used ChatGPT or another artificial intelligence chatbot has likely seen a disclaimer that its answers may be incorrect. Large language models are built to generate the most probable response to a prompt. Even ...
Tech Xplore / A continuous artificial muscle unlocks dexterous soft-robot motion
An octopus can bend one part of an arm around an obstacle while another reaches into a small crevice to grab an object. Reproducing that local control in a soft robot requires multiple actuators—components that turn energy ...
Tech Xplore / Far-UVC LEDs transmit data at record speed
Researchers at Ferdinand-Braun-Institut (FBH) in Berlin and collaborating institutions have transmitted data at up to 1.5 gigabits per second using novel far-UVC LEDs. The devices, developed at FBH, set a record for wireless ...
Tech Xplore / Prussian blue improves perovskite solar performance from small cells to larger modules
Perovskite solar cells (PSCs) are a promising next-generation photovoltaic technology that can achieve high power conversion efficiencies. However, their performance and long-term stability are limited by problems that arise ...
Tech Xplore / Stretchable sensory device converts underwater ultrasound into artificial neural signals
A research team led by Nae-Eung Lee, a professor at the School of Advanced Materials Science and Engineering at Sungkyunkwan University (SKKU), has developed a material that can stretch like rubber while generating electricity. ...
Tech Xplore / Researchers offer three ways to alert users to AI hallucinations with 'embodied' agents
When a conversational AI character in an immersive environment says something false, how should the system alert the user? Researchers have now explored this question in a proof-of-concept study, which tested three techniques ...
Tech Xplore / Lithium-ion 'traffic jams' ease with additive that helps unlock energy in thicker battery electrodes
To develop batteries that last longer on a single charge, more energy must be stored without increasing their size or weight. A research team led by Dr. San Moon and Dr. Jungdon Suk at the Korea Research Institute of Chemical ...
Tech Xplore / The tests that grade AI may be getting it wrong
Before a new AI model reaches the public, its developers run it through a battery of tests known as "benchmarks," which score it on everything from reasoning ability to how safe it is for people to use. Billions of investment ...
Tech Xplore / Insect-inspired approach uses metals to tune strength and flexibility within one material
Researchers from the Biointegrated Materials and Engineering group at the Institute for Bioengineering of Catalonia (IBEC) have shown that adding trace amounts of different metal ions to chitosan can locally tune how stiff, ...
Tech Xplore / 3D-printed materials reveal where damage develops with real-time electrical imaging
An international team of engineers has adapted a medical imaging technique to give 3D-printed materials the ability to sense where they are being damaged and track how that damage develops in real time.
