Technology called lidar is revolutionizing archaeology. By measuring the distance light travels to the ground and back, researchers can digitally strip away the canopy from forested areas like Mosquitia, in Honduras--revealing ancient settlements.
Usually, light waves do not interact with each other. Coupling of photons with other photons is only possible with the help of special materials and very intense light. Scientists in Vienna have now created the strongest .
