Monday Science Links

This week's sciency goodness:

• Joseph at Corpus Callosum writes about a man with an astonishing brain condition - you really have to see the MRI
  
• Chad at Uncertain Principles explains how polarized sunglasses actually work and why you should get some.
• Jen at Cocktail Party Physics explains shiny things, or why opals are so pretty.
• Kristjan at Pro-science writes about a paper on how pterosaurs might have fed (and points you to the PLoS paper for follow-up if you're so inclined).
• Larry at Sandwalk has a mammoth series on DNA - reading for several days, at least.

Have fun!
