A Dartmouth study reports a technique for creating detailed landscape maps of what students know based on their performance on short multiple-choice quizzes. The researchers’ mathematical framework could be used to power a new generation of personalized AI tutors that can identify what individual students do and do not understand, then customize feedback to improve learning. The researchers released a public demo where users can construct an interactive map of their knowledge.

Researchers in China developed a novel visual system, the VSES2-4 systems enabled rapid identification of transgenic soybean plants under natural light. Using the VSES4 system, transgenic plants could be distinguished at various developmental stages without compromising genome editing efficiency. The VSES4 system significantly accelerates transgenic line screening and reduces labor-intensive procedures in soybean genome editing.

Engineered transfer heads could eventually be used to repair defective pixels in microLED screens or assemble complex and multi-material electronics.

The aerospace and manufacturing industries face a persistent physical contradiction: materials that block noise are typically too weak to support heavy loads, and strong structural materials lack the porosity needed to absorb sound.

Publishing in the International Journal of Extreme Manufacturing, researchers have merged acoustic engineering with robotic 3D printing to create a carbon-fiber composite that swallows sound waves while retaining the strength of industrial load-bearing panels.

A comprehensive review published in Neuroelectronics sheds light on the latest advancements in wireless power and data transfer (WPDT) systems for implanted medical devices (IMDs), and outlines innovative solutions to enhance power transfer efficiency (PTE), data communication, and biosafety, thereby providing a reliable reference for the future design of IMDs.
