Tech Xplore / Spelling backward gets easier for AI models upgraded to see every letter
Before large language models (LLMs) can process text, they split it into chunks such as words or word fragments. The LLM behind ChatGPT, for example, splits "LMU München" into the three chunks "LM," "U" and "München," so ...
Tech Xplore / Coal-derived carbon nanodots enable next-generation 2D electronics
Silicon-based microelectronics have powered the digital revolution, but their performance and efficiency are starting to reach limits imposed by the fundamental properties of silicon itself.
Tech Xplore / Shape-sensing sheet digitally tracks its movement as it bends and twists
MIT engineers have developed a flexible, shape-sensing sheet that digitally reconstructs its own form as it bends and twists. The sensor is similar in principle to some motion-capture garments, which track a person's physical ...
Tech Xplore / AI evaluations of job candidates look unbiased without being fair
Companies seeking to fill job openings are increasingly "drinking through a fire hose of applications," in the words of one hiring expert, with some popular postings receiving 1,000 applications in a single weekend.
Tech Xplore / PhoneBot gives old smartphones a new job on two legs
Smartphones combine cameras, motion sensors and powerful processors in devices that fit inside a pocket. These features could also make them useful components for robots, reducing the need to buy and connect separate sensors, ...
Tech Xplore / Simple math formula predicts when AI chatbots will go rogue
Most of us now carry in our pockets devices capable of running small AI chatbots. These chatbots have little safety oversight to ensure they don't provide information and answers with the potential to encourage self-harm, ...
Tech Xplore / Can your employer demand proof that you've slept well?
Fatigue can be just as dangerous as drunken driving. That is why both researchers and companies are increasingly investing in technologies that can monitor and improve our sleep. But what happens if sleep is no longer regarded ...
Tech Xplore / Platinum in fuel cells lasts longer with nitrogen-enhanced graphene wrapper
Researchers from Nagoya University in Japan have developed a durable fuel-cell catalyst by wrapping platinum nanoparticles in nitrogen-containing graphene and placing them on carbon nanotubes. This design retained 96.9% of ...
Tech Xplore / Autonomous vehicles can still see lanes through tampered sensors—but in the wrong place
Driver-assistance systems are now installed in nearly all modern cars. As a result, safety depends on whether computer systems can reliably process sensor data. Researchers at the Technical University of Munich (TUM) are ...
Tech Xplore / Heat-storing gel could cut buildings' energy consumption
Heating and cooling buildings account for a large portion of global energy use. A research team in the Texas A&M University Department of Materials Science and Engineering was featured on the cover of ACS Applied Materials ...
Tech Xplore / Overlooked indium selenide phase enables wafer-scale logic transistors
Just as carbon atoms arranged in different ways can form either graphite or diamond—the hardest natural material—semiconductor materials can also exhibit completely different properties depending on their atomic arrangements. ...
Tech Xplore / Simple modification improves commercial resin for direct air capture
To mitigate climate change, direct air capture of carbon dioxide (CO₂) from the atmosphere has emerged as an increasingly attractive option for limiting global warming. But scaling up systems to remove and safely store enough ...
