Welcome to the final links roundup of 2014. It's a little light this week, because, well, folks are busy with family and holidays and whatnot. Nonetheless, a few hardy souls still managed to feed the Internet some sweet, sweet content.

December 21 was the winter solstice. Vox had a post declaring that December 21, 2014 was the longest night in the history of Earth. Scientists on the Internet begged to differ and made a compelling case. So Vox did the classy thing and put up a new post: No, this winter solstice wasn't the longest ever. Scientists explain what we got wrong. That's how it's done, people. More on the winter solstice: How celestial events influenced ancient construction at Petra. Also: Solstice, Shmolstice – Why The Coldest Days Are Still To Come.

Looking forward, Will You Be Able to Float on January 4, 2015, a.k.a. "Zero G Day"? Hint: No. The Bad Astronomer explains.

Snowflakes were another common theme this week, starting with io9's Scientific Guide to Celebration: bust out some science with these DIY snowflakes. Related: Science Friday Explored the Science of Snowflakes With 'Snowflake Guru' Kenneth Libbrecht. We covered this at the cocktail party in 2011, too. Because it’s easy to miss the beauty of a snowflake if you don’t take a close look.

And yes, lots of folks celebrated Christmas this past week, so here's one last round of science-y things relating to that holiday -- specifically, Santa Claus. It's Okay To Be Smart host Joe Hanson took a hard scientific look at Christmas mysteries by explaining how physics apply to Santa Claus, why Christmas tree lights always get tangled (blame it on the second law of thermodynamics), and even offers a plausible explanation for Rudolph the Red-Nosed Reindeer’s red nose.
