    Understanding why rose petals curl: How stress, geometry, and biology shape their elegant forms

    2 hours ago

    Rose petals' unique shapes come from stress during growth. Differential growth and mechanical stresses create curled edges. Research shows petals violate a mathematical condition, causing stress. Scientists study petal formation using imaging and modelling. This knowledge inspires material science. Engineers design self-shaping materials based on these principles. Rose petals demonstrate nature's design efficiency.
