Discovery
In 1991 Russell G. Foster and colleagues, including Ignacio Provencio, discovered a non-rod, non-cone photoreceptor in the eyes of mice. It was shown to mediate circadian rhythms, i.e. the body's 24-hour biological clock. Foster was elected a fellow of the Royal Society in 2008. These novel cells express the photopigment melanopsin, which was first identified by Provencio and colleagues.

Famous quotes containing the word discovery:
“There is a great discovery still to be made in literature, that of paying literary men by the quantity they do not write.”
—Thomas Carlyle (1795–1881)
“Your discovery of the contradiction caused me the greatest surprise and, I would almost say, consternation, since it has shaken the basis on which I intended to build my arithmetic.... It is all the more serious since, with the loss of my rule V, not only the foundations of my arithmetic, but also the sole possible foundations of arithmetic seem to vanish.”
—Gottlob Frege (1848–1925)
“We early arrive at the great discovery that there is one mind common to all individual men: that what is individual is less than what is universal ... that error, vice and disease have their seat in the superficial or individual nature.”
—Ralph Waldo Emerson (1803–1882)
