"New research on how bees perceive colour could be put to good use in our digital cameras, meaning photos shot by drones or phones would look more natural than ever. It's all to do with colour constancy, the way that bees (and humans) can tell a flower is red no matter what the colour or quality of the light – a mental trick that the digital cameras of today really struggle with."

"Almost anything that flies, be it a plane, a spacecraft, or a drone, has an inertial navigation system with accelerometers and gyroscopes that control yaw, pitch and roll, and thus the flight path. Flying insects like bees, however, don't have inertial systems to guide them; they rely exclusively on what they see. This has inspired two researchers at the Aix-Marseille University in France to build a drone that imitates the way these insects navigate. Their mission was to design it to fly and circumvent obstacles by relying solely on visual cues. "

"Wind turbines produce 4% of the planet’s energy, but they only work well when the wind is blowing just right. Now, by drawing inspiration from the flexible wings of insects, scientists have found a way to make wind turbine blades 35% more efficient at producing energy. If commercialized, the advance could make this green technology a more viable alternative to fossil fuels in the coming years."

Another interesting example of design evolution. Those blades provide a good compromise between drag and net torque. It is a finite-size system which design is evolving to facilitate the flow of energy from the wind to a rotating axis. |
