The system could support faster analysis in education, government and business by automatically sorting related blocks of text into groups, or clusters. https://techxplore.com/news/2026-09-groups-english-text-accurately-conventional.html Computer Sciences Wed, 23 Sep 2026 13:40:09 EDT news709387494 For decades, the gold standard for capturing human movement and transferring these data into the digital world has required actors to wear suits with physical markers that cameras track in a specialized studio. While accurate, this capture process is time-consuming and expensive. Markers need to be placed manually, they can fall off, and if two people get too close—such as during a hug or a dance—the system fails to track all markers as one person blocks the other from the camera's view, and accuracy drops significantly. Extensive post-processing is needed to recover the motion in such challenging sequences. The creators of the Hollywood blockbusters "Avatar" or "The Lord of the Rings" will know what we mean. https://techxplore.com/news/2026-09-virtual-markers-smartphone-cameras-reconstruct.html Computer Sciences Tue, 22 Sep 2026 16:00:06 EDT news709310402 A new AI technology has been developed that retains and reuses knowledge, much like writing down a solution in a notebook and applying it to similar problems rather than asking an expert for help each time. https://techxplore.com/news/2026-09-smartphone-ai-solutions-tackle-similar.html Computer Sciences Mon, 21 Sep 2026 13:20:05 EDT news709213441 Researchers from Tokyo Metropolitan University have used an evolutionary algorithm to identify optimal shapes for ultra-thin, bio-inspired corrugated airfoils, the two-dimensional cut-throughs of wings.
