“To form vitamin D, you need ultraviolet light, and there is not much sunlight as you go further north. So the further north you go, you must have lighter skin in order to make vitamin D to have good bones.”
Keith Cheng
“Like ultraviolet rays memory shows to each man in the book of life a script that invisibly and prophetically glosses the text.”
Walter Benjamin
“I just did some looking around and found there are some butterflies that fluoresce under (ultraviolet light).”
Nathan Brockman
“Because BCD galaxies are metal poor and very compact, the intense ultraviolet radiation from young stars will destroy PAH molecules even if they are formed. The threshold for when these PAH molecules stop being destroyed is still uncertain.”
Yanling Wu
“We think that ultraviolet light may have affected the viability of the spores.”
Greg Shaner
“Our goal is now to understand how certain males keep a better plumage than others. Factors like ultraviolet radiation from the sun, soiling and even feather-degrading bacteria are known to affect the color of bird feathers once they are grown, and perhaps the best males are those who spend more time preening and protecting their plumage.”
Kevin McGraw
“They might do photosynthesis in the ultraviolet as opposed to the visual spectrum. It's a tremendous amount of energy if you can make use of it instead of being killed by it. It's unusual, but natural selection makes the best out of adversity.”
