Optics
The microscopic lens bends light to quicken data transfer in computers.
Scientists can identify plants by the light they reflect.
The elusive waves, once thought to be myths, are explained by the same math that's found in a wide range of settings.
Green spectrum light can actually damage plants.
Hummingbirds can distinguish blends of color that we see as ordinary hues.
What links a wildfire raging across a forest to the electric signals rippling through our hearts? Enter the world of waves in excitable media.
Instead of packing more pixels into displays, engineers are learning how to trick our eyes and brains to see higher resolutions in the virtual world.
Researchers developed a way to weld pieces of brittle ceramics together using a laser that fires a million times per second.
Regular improvements in so-called optical clocks are setting the stage for a redefinition of the second and powering searches for new laws of physics.
Researchers have embedded gold particles in soft films that dissipate light energy at the surface of the eye and could have future medical uses.
New proof of concept could guard against the disorienting effects of laser pointers invading the cockpit.
