Diversifying DNA origami: Generative design tools rely on grammatical rules to find optimal shapes
(A) The grammar rules in this work include triangulation of surface meshes. The distance d and rotation angle θ are user-defined values. (B) Grammar rules are randomly sampled and applied to evolve the design solution sn during the generation process. Credit: Nucleic Acids Research (2024). DOI: 10.1093/nar/gkae1268 As the name suggests, DNA origami is a fabrication technique in which researchers…

The science behind Christmas sweaters: How friction shapes the shape of knitted fabrics
(a) Photograph of jersey knit stitches. (b) Experimental setup. (c) Geometric and numerical model. Credit: arXiv (2024). DOI: 10.48550/arxiv.2404.07811 Through experiments, three physicists from the University of Rennes, Aoyama Gakuin University, and the University of Lyon discovered that it is the friction between the fibers that causes knitted fabric to take on a specific shape. Jérôme Crassou, Samuel Pointcru, and…
