This is what tiny droplets of oil look like when frozen under a microscope

These tiny oil droplets may hold a key to a new mechanism that drives the development of shapes and forms in nature, a process known as morphogenesis. When the droplets are slowly frozen, they shift through a range of different shapes. This shape-shifting is driven by a wax-like layer that forms beneath the surface of the droplets, suggesting that complex morphogenesis may be controlled by the physical properties of the materials themselves.
