Tech Xplore / Tiny OLED pixels can be manufactured like microchips using chemical-resistant polymers
Screens are becoming smaller and sharper. This can be seen, for example, in augmented reality glasses and the electronic viewfinders of cameras, some of which have a screen diagonal of less than 1 centimeter (0.4 inches).
Phys.org / Pigeons' proposed inner-ear compass runs into a noise problem
A pigeon turning its head might seem an unlikely electricity generator. Yet one proposed explanation for the bird's magnetic sense depends on exactly that: Turning through Earth's magnetic field would produce tiny electrical ...
