Schematic and experiment snapshots showing the individual and assembling behavior of bimodal droplets. Credit: Science Advances (2024). DOI: 10.1126/sciadv.adp1439 A team of engineers at the Max Planck Institute for Intelligent Systems, the Chinese University of Hong Kong and the Gwangju Institute of Science and Technology has found that ferrofluidic drops in a tank of water […]

Neural network learns to build maps using Minecraft

A predictive coding neural network explores a virtual environment. In predictive coding, a model predicts observations and updates its parameters using the prediction error. Credit: Nature Machine Intelligence (2024). DOI: 10.1038/s42256-024-00863-1 Imagine you are in the middle of an unknown town. Even if your surroundings are initially unfamiliar, you can explore around and eventually create […]

New technique pinpoints nanoscale ‘hot spots’ in electronics to improve their longevity

Rochester engineers have developed a way to spot tiny, overheated components that degrade electronics’ performance by borrowing methods from biological imaging. NOBEL NOD: Materials science PhD student Benjamin Harrington uses a wire bonder to add electrical connections to an electrical heater structure. The structure was designed as a test subject for a new heat mapping […]

New framework allows robots to learn via online human demonstration videos

Our proposed TieBot performs a tie-knotting task. We leverage cloth simulation to recover the tie’s motion from human demonstration and learn a goal-condition policy to accomplish the tie-knotting task. Credit: Peng et al. To be successfully deployed in real-world settings, robots should be capable of reliably completing various everyday tasks, ranging from household chores to […]
