Description
Liat Levavi and Benny Bar-On study how rose prickles grip without breaking, in this 2024 paper. A prickle is the sharp point on a rose stem. It works as a small anchor: it wards off animals that eat plants and helps the stem lean on nearby objects as it grows.
The pair looked at dog rose prickles at many scales, tested their stiffness, and ran computer models of stress inside them. They found design tweaks at each scale, from the shape of the whole point down to its inner structure. These tweaks lock stress into safe paths, so the prickle resists damage and keeps its shape instead of snapping. The authors suggest the same tricks could guide tiny anchors for medical tools, micro robots, and small machines that need a firm grip.
