Nobody likes buildings that are too hot in the summer or too cold in the winter. That's where the FlectoLine facade comes in, as it uses two bio-inspired mechanisms to regulate how much solar thermal energy gets through a building's windows.

Scientists have replicated the seed-delivery system used by wild oats, resulting in a seed-carrying bio-hybrid "robot." Scores of the tiny devices could one day be utilized for much easier, more effective aerial seeding of crops or even new forests.

Newly-created polymers liquefy and fill in scratches when exposed to UV light, then resolidify once the light source is removed.
