Every type of atom in the universe has a unique fingerprint: It only absorbs or emits light at the particular energies that match the allowed orbits of its electrons. That fingerprint enables scientists to identify an atom ...

A very large team of researchers affiliated with several institutions in China and Japan has measured the highest energy photon ever recorded. In their paper published in the journal Physical Review Letters, the group describes ...
MIT researchers have developed a novel "photonic" chip that uses light instead of electricity—and consumes relatively little power in the process. The chip could be used to process massive neural networks millions of times ...
