Journal that published faulty black plastic study removed from science index
The publisher of a high-profile, now-corrected study on black plastics has been removed from a critical index of academic journals amid questions about quality criteria, according to a report by Retraction Watch.
On December 16, Clarivate—a scholarly publication analytics company—removed the journal Chemosphere from its platform, the Web of Science, which is a key index for academic journals. The indexing platform tracks citations and calculates journal "impact factors," a proxy for relevance in its field. It's a critical metric not only for the journals but for the academic authors of the journal's articles, who use the score in their pursuit of promotions and research funding.
To be included in the Web of Science, Clarivate requires journals to follow editorial quality criteria. According to Retraction Watch, Chemosphere has retracted eight articles this month and published 60 expressions of concern since April.

A new, uncensored AI video model may spark a new AI hobbyist movement
The AI-generated video scene has been hopping this year (or twirling wildly, as the case may be). This past week alone we've seen releases or announcements of OpenAI's Sora, Pika AI's Pika 2, Google's Veo 2, and Minimax's video-01-live. It's frankly hard to keep up, and even tougher to test them all. But recently, we put a new open-weights AI video synthesis model, Tencent's HunyuanVideo, to the test—and it's surprisingly capable for being a "free" model.
Unlike the aforementioned models, HunyuanVideo's neural network weights are openly distributed, which means they can be run locally under the right circumstances (people have already demonstrated it on a consumer 24 GB VRAM GPU) and it can be fine-tuned or used with LoRAs to teach it new concepts.
Notably, a few Chinese companies have been at the forefront of AI video for most of this year, and some experts speculate that the reason is less reticence to train on copyrighted materials, use images and names of famous celebrities, and incorporate some uncensored video sources. As we saw with Stable Diffusion 3's mangled release, including nudity or pornography in training data may allow these models achieve better results by providing more information about human bodies. HunyuanVideo notably allows uncensored outputs, so unlike the commercial video models out there, it can generate videos of anatomically realistic, nude humans.

Krypto steals the show in Superman teaser
The Internet has been buzzing the last few days about James Gunn's Superman reboot slated for release next year. The studio released a "motion poster" earlier this week set to a moody cover of John Williams' "Superman March," as well as a teaser for a teaser for the film. That teaser just dropped.
Clearly, given all the buildup, what director James Gunn wants for Christmas is for everyone to get excited over his Superman movie. And you know what? It kinda worked, especially since Superman's dog Krypto makes an adorably welcome appearance.
Gunn describes his take as less of an origin story and more of a journey, with Superman struggling to reconcile his Kryptonian heritage and aristocratic origins with his small-town, adoptive human family. Gunn tapped David Corenswet to play Clark Kent/Superman, at 25 a bit more established than the young cub reporter of Smallville, for instance. Rachel Brosnahan plays Lois Lane, Skyler Gisondo plays Jimmy Olsen, and Nicholas Holt is arch-nemesis Lex Luther. (Holt's son shaved his head for the role.) Luther's sidekicks are played by Sara Sampaio as Eve Teschmacher and Terence Rosemore as Otis.
Amazon faces holiday strike after refusing to bargain with warehouse workers
Amazon workers at seven warehouses walked out Thursday morning, launching a strike ahead of the holidays after Amazon failed to meet a bargaining deadline set by the Teamsters union representing the workers.
In a press release, Teamsters declared it "the largest strike against Amazon in US history." Teamsters general president, Sean O'Brien, warned shoppers of potential delays, saying "you can blame Amazon’s insatiable greed."
"We gave Amazon a clear deadline to come to the table and do right by our members. They ignored it," O’Brien said. "These greedy executives had every chance to show decency and respect for the people who make their obscene profits possible. Instead, they’ve pushed workers to the limit and now they’re paying the price. This strike is on them."

Solving renewable energy’s sticky storage problem
When the Sun is blazing and the wind is blowing, Germany’s solar and wind power plants swing into high gear. For nine days in July 2023, renewables produced more than 70 percent of the electricity generated in the country; there are times when wind turbines even need to be turned off to avoid overloading the grid.
But on other days, clouds mute solar energy down to a flicker and wind turbines languish. For nearly a week in January 2023, renewable energy generation fell to less than 30 percent of the nation’s total, and gas-, oil- and coal-powered plants revved up to pick up the slack.
Germans call these periods Dunkelflauten, meaning “dark doldrums,” and they can last for a week or longer. They’re a major concern for doldrum-afflicted places like Germany and parts of the United States as nations increasingly push renewable-energy development. Solar and wind combined contribute 40 percent of overall energy generation in Germany and 15 percent in the US and, as of December 2024, both countries have goals of becoming 100 percent clean-energy-powered by 2035.
