Let's face it, the mid-December box office will be dominated by Avengers: Doomsday and Dune: Part Three, but for those seeking fun holiday family fare, Jumanji: Open World opens the very next week on Christmas Day. Sony Pictures just released a new trailer for director Jake Kasdan’s sequel to his 2019 hit, Jumanji: The Next Level, teasing the usual wacky hijinks with a twist that calls back to the original 1995 film.

As previously reported, Kasdan gave the franchise a welcome major overhaul with the release of 2017’s Jumanji: Welcome to the Jungle, updating the original board game into a vintage video game and giving us a hugely entertaining action-adventure. Welcome to the Jungle racked up over $960 million at the global box office and spawned the equally successful 2019 sequel Jumanji: The Next Level.

A third film was always in the cards: The Next Level featured a tantalizing mid-credits scene in which a heater repairman (Lamorne Morris) visits Spencer Gilpin’s (Alex Wolff's) house, sees the broken video game console, and inadvertently triggers the game. The COVID-19 pandemic paused the third film’s development, but things picked up again in 2024, and here we are. Per the official synopsis:

The end of the year is fast approaching and with it, the pre-Christmas release of Dune: Part Three, the final installment in Denis Villeneuve's acclaimed adaptation of sci-fi author Frank Herbert's novel(s). Warner Bros. gave us a broody and haunting extended teaser in March and a July trailer jam-packed with tantalizing hints of what to expect, along with plenty of Easter eggs to delight avid book fans. Now we've got one last action-packed trailer setting up the final act for iconic anti-hero Paul Atreides (Timothée Chalamet).

(Spoilers for first two films in the franchise below.)

Previously, 2021’s Dune culminated in the brutal defeat of House Atreides by rival House Harkonnen, with Paul and his mother, Lady Jessica (Rebecca Ferguson), fleeing to the desert and taking refuge among the Fremen. Among them is Chani (Zendaya), whom Paul has been seeing in visions all along.

Dating back to around 400 CE and made of dichroic glass, the Lycurgus Cup is notable for exhibiting different colors depending on the light. (It gets its name from the scene depicted on its surface, of King Lycurgus of Thrace.) Light it from the front, and the cup looks green; light it from behind, and the color changes to a deep red. University of Sheffield scientists have re-created the original recipe to produce a contemporary glass sculpture with the same optical effect.

The cup is considered one of the seven glass wonders of the world, one of just 40 glass cage cups that survived. Exactly why the unusual color effects of the Lycurgus Cup occurred was a mystery until 2007, when a team of scientists discovered the color shifts were due to the presence of nanoparticles in the glass—the result of Roman artisans adding finely ground gold and silver into the mix. Those nanoparticles change how the electrons in the cup vibrate in response to light so that the color one sees shifts with the observer’s vantage point.

As we reported in 2019, it’s a similar phenomenon to the one responsible for the shifting colors of 19th-century daguerreotypes due to the scattering properties of nanoparticles. The Romans added salt when they melted the silicon (sand) to make the glass, and those salts contained gold atoms. In the melting process, those atoms aggregate and produce nanoparticles, which in turn produce the colors. It’s how any stained glass is made. It's also similar to how the precise lattice-like structure of photonic crystals produces iridescent colors in nature, like the wings of butterflies, or opals.

Sir Arthur Conan Doyle created one of the most beloved fictional detectives of all time in Sherlock Holmes, spawning countless novels, films, TV series, and so forth featuring the sleuth. Far fewer people know about the real-life inspiration for Holmes: a renowned surgeon at Scotland's University of Edinburgh named Joseph Bell, who taught Doyle when the author was still a young medical student. Bell is the subject of a new, eminently readable biography, Sleuth-Hound: The Case of the Real Sherlock Holmes, by medical historian Lindsey Fitzharris.

A noted science communicator with a fondness for the medically macabre, Fitzharris published a biography of Scottish surgical pioneer Joseph Lister, The Butchering Art, in 2017—a great, if occasionally grisly, read. She followed up with 2022’s  The Facemaker: A Visionary Surgeon’s Battle to Mend the Disfigured Soldiers of World War I, about a WWI surgeon named Harold Gillies who rebuilt the faces of injured soldiers.

In 2020, Fitzharris hosted a documentary for the Smithsonian Channel, The Curious Life and Death Of…, exploring famous deaths, ranging from drug lord Pablo Escobar to magician Harry Houdini. Fitzharris performed virtual autopsies, experimented with blood samples, interviewed witnesses, and conducted real-time demonstrations in hopes of gleaning fresh insights. And last year she and her husband, caricaturist Adrian Teal, collaborated on an illustrated children's book, Dead Ends! Flukes, Flops, and Failures that Sparked Medical Marvels.

A 25-year-old German experimental photographer has won the 2026 Nikon Small World photomicrography competition with a striking image of droplets of ink being deposited on paper by an inkjet printer. Ole Bielfeldt beat out 1,802 other entries hailing from 69 different countries.

Bielfeldt became interested in photomicrography during the COVID-19 lockdown after discovering an old microscope in his parents' attic. He figured out how to build an adaptor out of a tube and some wood to connect the microscope to his father's camera and taught himself the art through trial and error, building custom tools as needed. He documents how he captures transformative images of everyday objects with behind-the-scenes videos posted to macrofying, his photography and videography brand.

It was Bielfeldt's curiosity about the inner workings of inkjet printers that inspired his winning entry, but capturing the action of ink drops being deposited on paper was a challenge, given that the process happens so quickly. The droplets, for instance, moved faster than the camera's shutter speed. Bielfeldt's solution was to deconstruct the printer so that the paper moved under a stationary (rather than moving) printhead, and then take the image in a dark room, using a flash to serve as the shutter, thereby freezing the ink drops mid-air. There was no need for pricey equipment. Bielfeldt does not use AI in his images, preferring to rely on traditional techniques.

Lord of the Rings: The Rings of Power returns next month for its third season. Prime Video unveiled a teaser earlier this year at San Diego Comic-Con, but we haven't heard much about the new season otherwise. We now have the official full trailer, and it's jam-packed with a rising Sauron, who is intent on conquering Middle-Earth with his army of Orcs—with the fractured opposition of elves, dwarves, and men scrambling to figure out how best to stop him. We also meet the human men who will become the Ringwraiths; the showrunners have dubbed them the Nazgnagol ("Rings-servant").

(Some spoilers for the first two seasons below.)

Prime Video made a major investment in The Rings of Power when it acquired the rights to the source material from the Tolkien estate, even committing to multiple seasons upfront. S3 is set seven years after the events of S2 and opens when the war between the elves and Sauron is at its height. Per the official synopsis:

Carrie White, the telekinetic prom queen from hell, is one of the most beloved horror icons in popular culture. First introduced in Stephen King's 1974 novel, Carrie, the character was immortalized in director Brian De Palma's 1976 adaptation, widely regarded as one of the best horror films of all time. It's certainly one of the best King adaptations. So Mike Flanagan faced a massive challenge when he signed on to create an eight-episode miniseries for Prime Video based on the book, released just in time to mark the 50th anniversary of de Palma's film.

I was among the skeptics who questioned why a Carrie miniseries was even necessary, although as a diehard Flanagan fan ("Flana-fan"?), I was willing to give him the benefit of the doubt. If anyone has an affinity for smartly adapting horror in general, and King's work in particular, it's Flanagan. And you know what? With one (very big) exception, Flanagan pulls it off, giving us a richly textured version of the story that is as much about kindness and lost innocence as bloody, vengeful rage—although we get plenty of the latter, too.

(Many spoilers below for the novel and the 1976 film, but there are no major reveals for the new series until after the second gallery. We'll give you a heads-up when we get there.)

The trailers for HBO's DC Universe series Lanterns teased a show that eschewed the usual superhero hijinks in favor of a gritty realism more in the vein of True Detective or Slow Horses. Personally, I liked the change. My verdict: Ignore the review bombing; it's wonderful. The season wrapped with an emotionally charged, almost elegiac finale that fully delivered on that initial promise. I've found the rebooted DC Universe films released thus far to be enjoyable but rather forgettable, even when the positives outweigh the negatives. But Lanterns is a shining beacon of what is possible when someone is allowed to get really creative within the genre.

(Spoilers below, but no major reveals.)

There are two primary storylines. The first takes place in 2016 with a mass shooting at a local football game in Rushville, Nebraska. Current Green Lantern Hal Jordan (Kyle Chandler) and his new trainee, John Stewart (Aaron Pierre), get involved in the investigation, to the annoyance of Sheriff Kerry Kane (Kelly Macdonald), who initially doesn't think the case has any extraterrestrial connection. She is soon proved wrong when the suspect (an alien) self-detonates. Hal's power ring controls the damage, but the mystery remains.

The Liberty Bell, with its famous crack, hasn't been rung in 180 years, but that hasn't stopped scientists from pondering what the bell might have sounded like when tolling. In honor of the nation's 250th anniversary, researchers at Penn State University have modeled its acoustic properties, drawing on data collected from one of the bell's replicas. The work was first presented at a meeting of the Acoustical Society of America in Philadelphia earlier this year, followed by an article in Physics Today.

Historians aren't sure exactly when the Liberty Bell acquired its distinctive crack, just that it occurred sometime between 1817 and 1846. An 1846 account in the Public Ledger described the ringing of the bell on February 23 that year and mentioned that the bell had developed a crack, which someone had attempted to fix by filing the sides down. But it didn't work: The February 23 ringing extended the crack even more, so much so that "the old Independence Bell ... now hangs in the great steeple irreparably cracked and forever dumb." Nobody has heard it ring since.

This wasn't the first time the bell had cracked; the rim cracked shortly after it arrived in Philadelphia in 1752, the first time the clapper struck while testing the sound. It was recast by two local foundry workers, John Pass and John Stow, not once but twice, because the first recast produced a sound that one bystander likened to coal scuttles banging together.

Director Greta Gerwig could have made pretty much any movie she wanted after 2023's Barbie racked up nearly $1.5 billion at the box office. She chose to make Narnia: The Magician's Nephew for Netflix, an adaptation of C.S. Lewis' sixth novel in The Chronicles of Narnia series. Gerwig has said little publicly about the film, other than that she was inspired by 1960s-era David Bowie, although she said it would not be a musical. Netflix just released the trailer, set to "Stairway to Heaven," and it's quite the psychedelic ride.

The first book in the series, The Lion, the Witch, and the Wardrobe, was published in 1950, and Lewis did not initially intend to write any more Narnia adventures. But then an acquaintance asked how the London lamppost ended up in the middle of Narnia's woodland, and Lewis was intrigued enough by the question to start a prequel, The Magician's Nephew, in order to find an answer. Lewis found it difficult to finish the book, however, writing four other Narnia books first before completing The Magician's Nephew in 1955.

There have been several adaptations, in various media, of The Chronicles of Narnia, most recently the early 2000s film franchise adapting the first three novels in the series. Those films showed diminishing returns, however, and by 2011 the film rights had expired. There were initial plans to adapt the fourth novel, The Silver Chair.

Honey bees are known to leave their stingers embedded in tender flesh once they sting you and fly away. Scientists have now determined that the stinger is able to continue pumping venom into its unfortunate victim even after the bee flies away, thanks to a unique double-piston pump-like mechanism, according to a new paper published in the Proceedings of the National Academy of Sciences.

Different species have evolved different mechanisms for delivering venom, which involves piercing the skin and then pumping venom from a gland or reservoir. Spiders, for instance, have muscles surrounding their venom glands, which contract and eject venom through hollow fangs. Bees, wasps, and ants deliver venom via their stingers, either by contracting muscles around the venom reservoir or through stiff elements called lancets working together to pump venom.

Honey bees (Apis mellifera) add a unique feature: Worker bees fly away after inserting their stingers in the target, leaving the stinger behind. The stinger continues to penetrate the tissue and pump venom on its own, a rare phenomenon known as autotomy. A honey bee's stinger has three main interlocking elements that form the venom canal: a stylet that widens to form the main pumping chamber and two sharp-tipped lancets that slide back and forth, piercing the tissue and pumping venom into the target. But the precise mechanism by which the pumping action is achieved has never been directly observed.

Elon Musk is a very familiar figure to Ars readers, given his massive influence (for better and worse) on the technology sector over the last 20 years. Oscar-winning director Alex Gibney's latest biographical documentary—simply titled Musk—covers a lot of well-known ground and challenges the carefully crafted public image of Musk as a visionary tech titan.

Gibney's documentary presents Musk as more of a Gilded Age confidence man, rejiggered for the 21st century: an investor cosplaying as an inventor whose real genius is pumping stocks and dazzling investors and the public alike with visions of a high-tech utopian future. The film is bound to push all the right outrage buttons, whether one is a Musk fan or a detractor—which makes it very much a product of the peculiar social media-driven era in which we live.

Gibney has been making documentaries since the 1980s, covering such varied subjects as Jimi Hendrix, Hunter S. Thompson and gonzo journalism, WikiLeaks, Scientology, Steve Jobs, Elizabeth Holmes (the subject of another forthcoming documentary, You Can See Everything, featuring comedian Nathan Fielder), Boris Becker, The Sopranos creator David Chase, alleged Russian interference in the US 2016 presidential election, the opioid epidemic, and cyclist Lance Armstrong. He snagged his first Oscar nomination for 2005’s Enron: The Smartest Guys in the Room, and won the Oscar for Best Documentary Feature two years later for Taxi to the Dark Side.

We got our first look at Prime Video's new sci-fi series Blade Runner 2099 in July at San Diego Comic-Con. With the show's premiere roughly six weeks away, the streamer unveiled the full trailer this weekend at New York Comic-Con. Co-stars Michelle Yeoh and Hunter Schafer (Euphoria) joined showrunner Silka Luisa (Shining Girls) onstage for the big reveal.

As Luisa described the show during the NYCC panel Saturday night:

We are 50 years after [Blade Runner] 2049 and, bad news, the worst has happened. The replicant uprising that has been bubbling up in the films has taken place and the humans have lost. So the creations have surpassed their creators. And the series, the big question it asks is, ‘What happens when our time as a species ends?’ 2099 is taking place at a junction point when one species is ending and a new one is rising. The first film, something I loved about it, was that it was looking at mortality on a micro level. Roy Batty and the other replicants were fighting for more life. This show asks that same question but on a macro level. Mankind—what happens when we realize our time is running out? And are we going to accept that loss? Can we hold on to our humanity during it?

Yeoh stars as Olwen, the dying Replicant, while Schafer plays Cora. The cast also includes Hugo Hamlet as Buster Friendly, as well as Dmitri Abold, Lewis Gribben, Katelyn Rose Downey, Daniel Rigby, Johnny Harris, Amy Lennox, Sheila Atim, Matthew Needham, Tom Burke, and Maurizio Lombardi—all in as-yet-undisclosed roles.
