In the category of lesser-known holidays that could be celebrated on December 25th, the coronation of William of Normandy in 1066 A.D. as first King of what we know as modern England would have to be considered.    It was the last time a foreign nation would conquer the island nation and years later the Brits gave us all Shakespeare, Christmas Island and America.

Given all the NASA funding, you think we'd get something from it!  Oh, wait, we do.  SpaceRef pointed me to the NASA SpinOff 2010 report.  What did we get for our $19 billion annual NASA budget?  I mean, that's a lot of money, that's... oh, wait, that's not a lot of money today.  My mistake.  True, you could buy 19 Stealth Bombers for that cost.  Or fight a typical war for 1 month.  But could you... save the airlines $2 billion in fuel costs with NASA wing mods?  Make a sensor that's in 1 in 3 cell phones?  Turns out we do get some bang for our buck.
Blue sharks in the Gulf Stream, in the western Atlantic, probably spend all day eating squid.

At first, that doesn't seem remarkable. Every big predator likes to eat squid, and sharks are no exception. And there are plenty of squid in the Gulf Stream, particularly Illex illecebrosus, which could arguably be referred to as the Humboldt squid of the western Atlantic. Illex illecebrosus and Dosidicus gigas are in the same family of large, muscular oceanic squid--Ommastrephidae--and they exhibit similar daily vertical migrations.
What do you get when you cross Science 2.0, the cultural buzzterm that really took off in 2010 (and brought with it a whole host of colloquial meanings veering into 'web 2.0-ish, it means whatever you want it to mean' jargon) with a western world Christmas season?

You get an excuse to do a compilation of science articles, that's what.

So once again this year I have compiled topical articles from this year and seasons past.
