Two years ago, it was announced that wherever the boundary of the solar system was, Voyager 1 had passed it, traveling further from Earth than any other manmade object. But some scientists insist it is still within the
Highly purified crystals that split light with uncanny precision are key parts of high-powered lenses, specialized optics and, potentially, computers that manipulate light instead of electricity. Producing these crystals often involves etching them with a precise beam of electrons and can be difficult and expensive.
Researchers at Princeton and Columbia universities have proposed a new method that could allow scientists to customize and grow these specialized materials, known as photonic
