Optics
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.
Scientists use ordinary equipment to reveal a hidden picture based on its shadow.
New imaging technique could help study the structure of viruses and proteins and the deformation of materials during high speed collisions.
Cells in the fly specimens' nervous systems can be seen glowing through the insects' transparent bodies.
New research finds the optical effect previously produced using strictly quantum techniques may have broader applications.
Physicists are exploring new ways to improve the accuracy of global clock networks essential to applications such as GPS.
Scientists have just found out that zinc sulfide, a relatively common semiconductor material, becomes pliable when kept in the dark.
