Happy New Year (belated), and welcome to 2019. We're back after several weeks' hiatus--although I still found time to write a special Twelve Days of Christmas series of science posts, plus a few others. And I've thrown in some of the physics stories you may have missed over the holidays for good measure.

The 12 Days of Christmas:

On the First Day of Christmas: New mass spectrometry hair analysis brings us one step closer to solving 1994 thallium poisoning case. The 1994 poisoning of Chinese student Zhu Ling left her permanently disabled.

On the Second Day of Christmas: Study concludes modern masters like Jackson Pollock were “intuitive physicists.” Another example: David A. Siquieros' "accidental painting" exploited paints of different densities.

On the Third Day of Christmas: Economists try to calculate the true value of Facebook to its users (as opposed to market value) in new study. Amounts varied, but some users required more than $1,000 to deactivate their account for one year.

On the Fourth Day of Christmas: Scientists performed CT scans on severed cat tongues from six different species. Conclusion: the unique structure of your cat’s tongue is ideally suited for grooming fur.

On the Fifth Day of Christmas: Caltech scientists use DNA tiles to play the world's smallest game of tic-tac-toe. They don't especially play it well, but being able to switch out tiles could one day lead to reconfigurable nanomachines.

On the Sixth Day of Xmas: Book tells the inside story of how Reddit came to be the Internet’s “id.” Tech journalist Christine Lagorio-Chafkin dishes the dirt on Reddit's founding in We Are the Nerds.

On the Seventh Day of Christmas: The secret to champagne’s universal appeal is the physics of bubbles. "It's a sad day when you drink flat champagne."

On the Eighth Day of Christmas: Let’s kick off 2019 by pondering the dismal future prospects for humanity. UK Astronomer Royal Lord Martin Rees chats with Ars about his latest book On the Future.

On the Ninth Day of Christmas: Study: Famed Domesday Book was completed later than historians thought. Satellite documents preserved by a Benedictine abbot named Nigel place its date between 1098 and 1114.

On the Tenth Day of Christmas: Machine learning can offer new tools, fresh insights for the humanities, from the French Revolution to the history of the novel. [Image: Association of Cybernetic Historians]

On the Eleventh Day of Christmas: Lose yourself in this highly addictive “murder map” of medieval London. It's like a 14th century game of Clue. It was the priest with the long knife in the garden.

On the Twelfth Day of Christmas: Quantum physicists in the 1920s helped found field of quantum biology, much earlier than you might have thought. Niels Bohr, Erwin Schroedinger, and others pondered link between life and physics.

Also Me at Ars Technica:

Trust the Process: No more doubts: Two independent studies confirm LIGO’s Nobel discovery. But Danish group that first raised doubts refuses to accept it was wrong.

All Hands on Deck: The Orville blends science fiction and science fact into a winning mix. I sat down on set with writer/producer and science advisor Andre Bormanis as the FOX series makes its season 2 debut.

Share and Share Alike: Few people shared fake news in 2016 election, but seniors shared the most. Less than nine percent of Facebook users surveyed shared links to fake news.

Dial Code: Santa Claus is our new favorite holiday cult classic. Restored version of 1989 French film was featured at this year's Fantastic Fest.

Hocus Pocus: Chilling Adventures of Sabrina charms with some welcome holiday horror. Netflix horror series' strong first season rewarded with sixteen new episodes.

The Long Night is Coming: Here’s what we know so far about long-awaited Game of Thrones prequel. Speculation abounds, but it's likely to focus on Age of Heroes and The Long Night.

Fist of Fury: Captain Marvel's Carole Danvers shows off her very own ‘Iron Fist’ in latest trailer. We catch a glimpse of a young Agent Coulson, but Jude Law's role remains murky.

Assassination Nation: Mads Mikkelsen goes full-on John Wick in new trailer for Netflix‘s Polar. He rocks a stylin' eyepatch and nifty laser gloves that control his ample artillery.

Our Own Worst Enemies: All we want for Christmas is the first trailer for Jordan Peele’s new horror film, Us, the much anticipated follow-up to 2017's amazing Get Out.

Sugar and Spice: There’s suspense but little magic in new teasers for Amazon’s series adaptation of Hanna. Esme Creed-Miles of Dark River fame takes on the titular role.

His Red Right Hand: Big Red’s Right Hand of Doom is back in fiery new Hellboy trailer. Director Neil Marshall's reboot tries to set itself apart from its predecessors.

The Last Suit She'll Ever Wear: Thor Ragnarok stars reunite, kick alien butt in Men in Black International trailer. Liam Neeson co-stars with a special set of skills. Did aliens kidnap his daughter?

Frank Castle is back to his vigilante ways in trailer for The Punisher Season 2: "Let me be what I'm meant to be."

And I contributed to these two group efforts:
