Peeking inside AI brains: Machines learn like us

A new study in Nature Communications found that AI models exhibit a geometric property called convexity, which helps humans form and share concepts. Convexity is also linked to the performance of AI models on specific tasks.

Ice-ray patterns: A rediscovery of past design for the future

A study discovers that traditional Chinese ice-ray lattice designs can provide unique stiffness and strength under asymmetric loads, offering an alternative to conventional gridshells. The research also explores the potential of integrating complex geometry into facade design and micro-scale material design.

New geometric deep learning model for detecting stroke lesions

A new geometric deep learning model called GFCN has been developed to detect stroke lesions in brain imaging scans. The model leverages rich geometric information to segment brain tissue and achieves higher segmentation performance than other neural network architectures.

Sky & Telescope Pocket Sky Atlas, 2nd Edition

Sky & Telescope Pocket Sky Atlas, 2nd Edition is a durable star atlas for planning sessions, identifying targets, and teaching celestial navigation.

Non-Euclidean geometries for grid cells

Scientists developed a new model to simulate grid cells in non-Euclidean spaces, revealing heptagonal symmetry on a pseudospherical surface. This finding suggests that the brain may be able to encode non-conventional geometries and abstract spaces.
