It's January, and for people in the US, that means the same thing it's meant every January since 2019: a new batch of previously copyrighted works have entered the public domain. People can publish, modify, and adapt these works and their characters without needing to clear rights or pay royalties.

This year's introductions cover books, plays, movies, art, and musical compositions from 1929, plus sound recordings from 1924. Most works released from 1923 onward are protected for 95 years after their release under the terms of 1998's Sonny Bono Copyright Term Extension Act. This law prevented new works from entering the public domain for two decades.

As it does every year, the Duke University Center for the Study of the Public Domain has a rundown of the most significant works entering the public domain this year.

Samsung is starting 2025 with a fresh attempt at popularizing 3D displays. Announced today, Samsung’s Odyssey 3D is the follow-up to prototypes that Samsung demoed at last year's CES technology trade show. This year, Samsung is showing off a final product, which is supposed to make 2D content look 3D.

Those who have dealt with 3D glasses may be relieved to hear that the Odyssey 3D doesn't require them. According to the South Korean company’s announcement, the monitor's use of a lenticular lens that is “attached to the front of the panel and its front stereo camera" means that you don't have to wear glasses to access the monitor's “customizable 3D experience.” Lenticular lenses direct different images to each eye to make images look three-dimensional. This is a notable advancement from the first 3D monitor that Samsung released in 2009. That display used Nvidia software and Nvidia shutter glasses to allow users to toggle between a 2D view and a 3D view through a few button presses and supported content.

Another advancement is the Odyssey 3D's claimed ability to use artificial intelligence “to analyze and convert 2D video into 3D.” We’ve recently seen similar technology from brands like Acer, which announced portable monitors in 2022 and then announced laptops that could convert 2D content into stereoscopic 3D in 2023. Those displays also relied on AI, as well as a specialized optical lens and a pair of eye-tracking cameras, to create the effect. But unlike Acer's portable monitors, Samsung claims that its monitor can make 2D content look like 3D even if that content doesn’t officially support 3D.

The first meteor shower of the year peaks on the night of January 2–3. Here’s everything you need to know to watch it and the many other showers that will appear in 2025.

Squid Game's hotly anticipated second season debuted on Netflix the day after Christmas and racked up more than 68 million views in just three days. It had already been renewed for a third and final season—filmed back-to-back with S2—but Netflix ushered in the new year by gracing us with a 15-second teaser on X, introducing a brand new killer doll dubbed Chul-su—similar to the giant "Red Light, Green Light" doll Young-hee.

(Spoilers for S1 below; some spoilers for S2 but no major reveals.)

As previously reported, the first season followed Seong Gi-hun (Lee Jung-Jae, seen earlier this year in The Acolyte), a down-on-his-luck gambler who has little left to lose when he agrees to play children's playground games against 455 other players for money. The twist? If you lose a game, you die. If you cheat, you die. And if you win, you might also die.

Carbon fiber, aluminum, maybe the odd bit of titanium here or there: These are the materials we usually expect race cars to be made of. Now you can start adding thermoplastics like Ultem to the list. Additive manufacturing has become a real asset in the racer’s toolbox, although the technology has actually been used at the track longer than you might think.

"Some people think that 3D printing was invented last year," said Fadi Abro, senior global director of automotive and mobility at Stratasys. The company recently became NASCAR's official 3D printing partner, but it has a relationship with one of the teams—Joe Gibbs Racing—that stretches back two decades.

"Now the teams only have certain things that they can touch in the vehicle, but what that does is it makes it so that every microscopic advantage you can get out of that one tiny detail that you have control over is so meaningful to your team," Abro said.
