Yellow pond-lily prefers cyclic flowers to spiral ones

Biologists from Lomonosov Moscow State University and HSE University have studied the patterns of flower development in yellow water-lily (Nuphar lutea). They found out that all the floral organs are arranged in cycles (whorls) ...

Emergence of chirality and structural complexity in single crystals at the molecular and morphological levels

Imagine trying to build a Colosseum-type edifice—including arches, vaults and various protrusions—while abiding by two strict rules: Only one type of brick may be used, and these bricks are required to be placed precisely, ...
