Taking a clue from jellyfish and squids that quickly alter their appearance via muscle-controlled morphology changes in their bodies’ surface structures, researchers have designed polymeric materials that change appearance reversibly in response to mechanically induced folds and deformations

"How do bees do it? The honeycombs in which they store their amber nectar are marvels of precision engineering, an array of prism-shaped cells with a perfectly hexagonal cross-section. The wax walls are made with a very precise thickness, the cells are gently tilted from the horizontal to prevent the viscous honey from running out, and the entire comb is aligned with the Earth’s magnetic field. Yet this structure is made without any blueprint or foresight, by many bees working simultaneously and somehow coordinating their efforts to avoid mismatched cells."

The evolution of design, configuration, structure, organization is a natural phenomenon. Evidence massively supports it. There's no designer, there's only the Constructal Law.
I challenge anyone to count the percentage of "mathematical hexagons" in a honeycomb. |

Scientists have discovered a previously unknown property of spider silk, and used it to create a remarkable new “hybrid” material. The new bio-inspired thread, which acts like both a solid and a liquid, could lead to a host of new materials and technologies.
