The research was initiated after scientists on the research team reported seeing occasional flashes of green light while working with an infrared laser. Unlike the laser pointers used in lecture halls or as toys, the powerful infrared laser the scientists worked with emits light waves thought to be invisible to the human eye.
Emmental cheese. Emmental (Emmentaler or Emmenthal) is a yellow, medium-hard Swiss cheese that originated in the area around Emmental, Canton Bern. It has a savory, but mild taste. While the denomination Emmentaler Switzerland is protected, Emmentaler alone is not; similar cheeses of other origins, especially from France and Bavaria and even Finland, are widely available and sold by that name.
Swiss Emmental is made from raw milk from cows who've fed on grass and hay, but never silage. The giant 200-pound Emmental wheels are about 45 inches in diameter and up to 9 inches thick. The thin, hard rind ranges in color from pale yellow to yellow-brown and the ivory-yellow interior has a supple, smooth texture and a random scattering of cherry- to walnut-size eyes. Emmental has a buttery, delicately sweet, earthy, fruity flavor.
