Tech Xplore / Alive or not? Tiny 3D-printed robots that swim and navigate just like animals
Leiden researchers Professor Daniela Kraft and Mengshi Wei have created microscopic robots that move without sensors, software, or external control. Instead, their behavior emerges entirely from their shape and the way they ...
Tech Xplore / Integrated strategy unlocks 29.76% efficiency for all-perovskite tandem solar cells
Two stacked layers comprise tandem solar cells (TSCs), with each subcell absorbing different wavelengths of sunlight, which makes TSCs more efficient than single-layer solar cells. All-perovskite TSCs hold great promise for ...
Tech Xplore / Molecular umbrella can protect solar cells by blocking ion migration
Perovskites are semiconducting materials that have rapidly transformed the field of optoelectronics, demonstrating outstanding performance in light-emitting diodes (LEDs) and photodiodes. For their unique properties, they ...
Tech Xplore / Nvidia's new AI tool is giving female game characters a makeover—and gamers are pushing back
Last week leading chipmaker Nvidia announced DLSS-5 (Deep Learning Super Sampling), a new artificial intelligence (AI) rendering tool it describes as a "breakthrough in visual fidelity for games." The software takes low-resolution ...
Tech Xplore / Yahoo turns to AI-powered answer engine Scout to lead it back to its roots in online search
Internet trailblazer Yahoo is exploring technology's next frontier with Scout, an answer engine powered by artificial intelligence. Scout seems insightful, based on its response to a question posed by The Associated Press ...
Tech Xplore / Molecular interface tuning lifts tandem solar cell efficiency to 25.1%
Researchers at UNIST have unveiled a novel interface engineering technique that significantly improves both the performance and durability of perovskite/organic tandem solar cells (POTSCs). Published in Energy & Environmental ...
Tech Xplore / Scheimpflug cameras may extend LiDAR-like sensing from 6 m to 4 km
An optical principle discovered more than a century ago may soon find new applications in such areas as monitoring atmospheric turbulence, tracking airborne objects, and mapping the environment, thanks to researchers at the ...
Tech Xplore / ChatGPT's taste for literary nonsense sparks alarm
OpenAI's GPT models can often be fooled into declaring that "pseudo-literary" nonsense is great, a German researcher has found.
Tech Xplore / Holographic storage approach packs more data into the same space by encoding three properties of light
Researchers have developed a holographic data storage approach that stores and retrieves information in three dimensions by combining three properties of light—amplitude, phase and polarization. By allowing more data to be ...
Tech Xplore / Bat-inspired ultrasound helps palm-sized drones navigate fog and smoke
A team led by Worcester Polytechnic Institute (WPI) researcher Nitin J. Sanket has shown that ultrasound sensors and a form of artificial intelligence (AI) can enable palm-sized aerial robots to navigate with limited power ...
Tech Xplore / Video-based AI gives robots a visual imagination
In a major step toward more adaptable and intuitive machines, Kempner Institute Investigator Yilun Du and his collaborators have unveiled a new kind of artificial intelligence system that lets robots "envision" their actions ...
Tech Xplore / AI overly affirms users asking for personal advice, study finds
In a new study published in Science, Stanford computer scientists showed that artificial intelligence large language models are overly agreeable, or sycophantic, when users solicit advice on interpersonal dilemmas. Even when ...
