ZME Science: Researchers at Washington University in St Louis have developed a camera that captures images at 100 billion frames per second. Using compressed ultrafast photography (CUP), they have created videos of four fundamental physical phenomena: “laser pulse reflection and refraction, photon racing in two media, and faster-than-light propagation of non-information"— motion that appears faster than the speed of light but cannot convey information. The results are found in their paper published in Nature. Such a camera could be used in various fields, including biomedicine to study cellular environmental conditions, astronomy to study the temporal activities of supernovae, and forensics to study the trajectory of a bullet.
