Brain implants evolved to use less energy - New Scientist - New Scientist: "After 10,000 generations, the optimum waveform emerged: a bell curve with the lower parts of each side cut short by a vertical line. Tests with implants in cats showed the waveforms were beneficial and minimised energy use. Grill says an implant using this waveform would need its batteries replaced five or six times over 30 years instead of eight to 10 times"
