Sunspots 496

Things I have recently spotted that may be of interest to someone else:

Education: A former University of North Carolina football player has filed suit, claiming that the university did not provide him with the substantial education that he was promised when recruited. (The university apparently let some students "take" classes that they didn't even attend.)
Health: (or not) We're running out of chocolate, according to The Washington Post and other outlets.
Science: Wired reports on how a study of the cat genome sheds some light on how domestic cats are genetically different from their wild relatives.

National Public Radio has a fine series on color. One post is about how our perception plays tricks on us when we are considering color. Another is about how animals get color from what they eat, partly -- flamingos are an example -- and how rare blue coloring in animals is.
Wired also reports on nudibranches, sea slugs, who eat defensive mechanisms from other creatures, and use them to defend themselves. They are also spectacularly colored -- some are blue.
