Sony releases trailer for Taika Waititi's Klara and the Sun

One of Taika Waititi's greatest strengths as a director is his unique voice; he's able to bring a light touch to tragedy (Jojo Rabbit) and a gentle sadness to offbeat comedy (Our Flag Means Death). That makes him an excellent choice to direct Klara and the Sun, based on the novel by Kazuo Ishiguro. Sony Pictures just released the first trailer, and it's giving strong Hunt for the Wilderpeople vibes—a good thing, from my perspective, since that's my favorite Waititi film.

Per the official premise:

Based on the bestselling novel from Nobel Prize winner Kazuo Ishiguro and written and directed by Academy Award winner Taika Waititi, Klara and the Sun introduces audiences to Klara (Jenna Ortega), an Artificial Friend who wants nothing more than to find the perfect home. When Klara meets Josie (Mia Tharia), each immediately senses a kindred spirit in the other. Josie has a fraught relationship with her mother (Amy Adams), and they’ve suffered great loss, but Klara’s innocent wonder and unwavering loyalty begin to heal the family and bring light to Josie’s complicated world.

The cast also includes Natasha Lyonne as an artificial friend (AF) store manager; Rachel House as the housekeeper, Melania; Aran Murphy (son of Cillian Murphy) as Josie's best friend, Rick; and Sophia Bryant-Taukiri as Josie's older sister, Sal. Steve Buscemi and Harry Greenwood also appear in as-yet-undisclosed roles.

How to burst the AI bubble: Strike at its roots

Last year, we featured a lengthy interview with tech journalist/science fiction author Cory Doctorow about his book, Enshittification: Why Everything Suddenly Got Worse and What To Do About It. The prolific Doctorow is back with a provocative new book that serves as a follow-up of sorts, focusing on AI and related issues: The Reverse Centaur's Guide to Life After AI.

Doctorow doesn't actually enjoy talking about AI, but he's constantly being asked to comment on it. "I made the tactical error of being sick of talking about AI," Doctorow told Ars. "So I wrote a book about why I think it's a dumb thing to keep asking people to talk about, and now I have to talk about it." Reverse Centaur is Doctorow's attempt to "sort out the bullshit from the material reality."

In automation theory, per Doctorow, a "centaur" describes a human augmented with a technology, like machine learning, or even just driving a car or using autocomplete. A reverse centaur "is a machine head on a human body, a person who is serving as a squishy meat appendage for an uncaring machine," Doctorow said in a speech last December. He gave the example of an Amazon delivery driver, surrounded by AI cameras monitoring their driving, who essentially serves as a peripheral to the delivery van.

Review: Widow's Bay is a boldly original take on comedic horror

Widow's Bay, the delightfully eccentric new comedic horror series from Apple TV, is easily one of the best new series of the year. There's a reason everyone from Guillermo del Toro and Ben Stiller to Damon Lindelof (Lost) is raving about the show. It's an eminently binge-able, addictive series that pays tribute to all the classic horror tropes while reinventing them in surprising ways. Think Stephen King meets Parks and Recreation, with a dash of Twin Peaks—except Widow's Bay is very much its own refreshingly original beast.

(Some spoilers below but no major reveals.)

Tom Loftis (Matthew Rhys) is a widower and mayor of Widow's Bay, a quirky little seaside town that has a colorfully bizarre history marked by periodic tragedies. Tom is eager to elevate the town into a trendy summer tourist destination. But the arrival of New York Times travel writer Arthur Lloyd (Bashir Salahuddin), who has the clout to make Tom's aspirations for Widow's Bay come true, coincides with the onset of a mysterious fog. Local resident Wyck (Stephen Root) warns Tom that the fog is an omen that the island is "waking up," meaning more supernatural occurrences are bound to happen.

We're about six weeks out from the debut of Spider-Man: Brand New Day, the follow-up to 2021’s No Way Home. It's been five years since Spidey graced the big screen, so naturally, Sony Pictures has released a new trailer to build audience anticipation.

(Spoilers for No Way Home below.)

No Way Home ended on a pretty bleak note, with Peter Parker (Tom Holland) asking Doctor Strange (Benedict Cumberbatch) to erase him from everyone’s memory to protect the multiverse, including MJ (Zendaya).

Did a medieval flying monk spot Halley's comet, twice? It's complicated

Early in the 11th century, a young Benedictine monk named Eilmer jumped from the 150-foot tower of his abbey in the small English town of Malmesbury, wearing a pair of crude wings he’d fashioned from willow wood and cloth. Eilmer managed to glide a good 600 feet, passing over the city wall before crash-landing in a small valley near the river Avon. The fall broke both his legs, crippling him. Malmesbury Abbey still boasts a stained-glass window in honor of Brother Eilmer.

This legendary experiment in medieval aviation comes to us via 12th-century historian William of Malmesbury in an account written circa 1125, although William neglected to provide future historians with an exact date for the feat. But William does mention another key episode in Eilmer's life when the monk was "advanced in years": Eilmer witnessed Halley's comet in 1066, commenting, "It is long since I saw you." Some historians have interpreted this to mean that Eilmer saw Halley's comet on an earlier fly-by in 989, when he would have been a young boy.

Assuming Eilmer was at least 5 years old in 989, he would have been born no later than 984. This would make Eilmer in his 80s in 1066, with his attempt at flight—which occurred when he was "in his first youth"—likely falling between 1000 and 1010. However, it's an estimate that is based on a lot of assumptions, according to James Aitcheson of the University of Leicester, who argues in a paper published in the journal Notes and Queries that Eilmer may have seen a different comet altogether in his youth—the comet of 1018. If so, he would have been born much later, and the date of his flight would have occurred between the 1020s and 1040s.

Review: Disclosure Day is big on action, light on ideas

The summer blockbuster season has kicked off in earnest with the theatrical release of Disclosure Day, director Steven Spielberg’s highly anticipated return to his “aliens are among us” sci-fi roots. Verdict: There's not much fresh or original here as movies about aliens go, but it's a fast-paced film with a luminous performance by Emily Blunt that won't fail to entertain.

(Some spoilers below but no major reveals.)

The first half of the film is essentially a political thriller—shades of 1974's The Parallax View and similar films—as global tensions have the world teetering on the brink of World War III. A cybersecurity specialist named Daniel (Josh O'Connor) has stolen a piece of alien technology and highly classified files from his employer, Wardex Corporation, a top-secret extension of the US government led by Noah Scanlon (Colin Firth). Scanlon flushes out Daniel by holding his girlfriend Jane (Eve Hewson) hostage. At the trade-off, Daniel double-crosses them and escapes with Jane, and the two go on the run as Scanlon declares Daniel a traitor.

Did Iron Age Britons remove brains of the dead?

Very little is known about funerary practices in Iron Age Britain, since few human remains have survived. However, the environment in northwest Scotland is more conducive to preserving bone from that period. Archaeologists have previously noted evidence of postmortem manipulation of human remains, such as mummification, and of modifying human bones into tools or decorative artifacts. Now a new paper published in the journal Antiquity describes evidence of postmortem brain removal in remains from that region, as well as sharpened limb bones, possibly for use as tools.

The remains in question were found in 2000 at a burial cairn in Loch Borralie, near the most northwest tip of the Scottish mainland, after erosion revealed a human cranium. The excavated remains belonged to two individuals: one an adult female and the other a juvenile of (at the time) indeterminate sex; the cranium belonged to the latter. The authors of the new paper conducted a fresh osteoarchaeological analysis as well as multi-isotope and ancient DNA analysis. Radiocarbon dating of molar teeth from both sets of remains placed their deaths as occurring between 50 BCE and 70 CE.

In the case of the female individual, the authors noted an unusual break at the base of the cranium that likely occurred near the time of death. It's the kind of fracture that one gets from high-velocity impacts, including vehicular collisions, sporting accidents, falls, assaults, or even long-drop hanging. But the known forensic patterns observed in the aforementioned scenarios don't exactly match the pattern of the Iron Age cranium, leading the authors to conclude that it likely resulted from a targeted impact. They also noted perimortem fractures on both scapulae.

Three key vital signs make up the "urban pulse" of a city

People often speak metaphorically of the heartbeat or pulse of a city, but according to the authors of a new paper published in the Proceedings of the National Academy of Sciences, cities do indeed have an "urban pulse"—an indication of urban "metabolic activity" that can be measured to suss out telltale patterns. And those patterns could help inform future public policy around urban planning.

The precise definition of urbanization has shifted over the centuries. Zhe Zhu of the University of Connecticut and his fellow authors adopted a broad version for their study. It features fundamental "processes of concurrent change in at least six dimensions, including demography, economy, infrastructure, environment, governance and culture," they wrote. "Together they give rise to outcomes, measurable results of the process, such as population growth, urban land expansion, GDP growth, and innovation." Their chosen metrics reflect this dynamic view: Cities are not static grids but "living, adaptive ecosystems."

“For decades, we had just been capturing the outcome of urbanization—a house that’s been built, or a road expansion,” said Zhu. “But you don’t really see the dynamics within an urban area. This is going to be a very impactful tool influencing not only top-down policy decisions from governments but also bottom-up decisions from everyday people navigating their cities.” One day we may be able to check a neighborhood's "urban pulse" while house-hunting, for instance, or while scouting potential locations for a new business.

RIP Anthony Head: Our 10 favorite moments of Buffy’s Giles

On Friday, news broke of the passing of actor Anthony Head at 72, best known for his portrayal of Watcher/father figure Rupert Giles on the supernatural drama Buffy the Vampire Slayer. Fans and former costars alike flooded social media with outpourings of appreciation for his talent and grief at his death.

Head certainly had a thriving career after Buffy: he played Uther Pendragon in the series Merlin; the Prime Minister in Little Britain; a sinister headmaster in the Doctor Who episode "School Reunion"; and of course, the wealthy, entitled Rupert Mannion in Ted Lasso. But Giles remains his definitive role; there was even talk of a spinoff series, Ripper, although it was never made.

There are actually very few Giles-centric episodes, which belies the central importance of the character in the series. He definitely had some of the best, most cleverly cutting lines. But Head's true genius—and that of his character—lay in quietly filling in the gaps in every scene, working with his fellow castmates to weave a complete tapestry. Remove him, and it diminishes everything.

Scientists ejected from diabetes conference for distributing journal reprints

Five leading scientists were ousted from the annual meeting of the American Diabetes Association (ADA) in New Orleans on Friday. Their crime: handing out copies of an editorial, published in the journal Diabetes Care on April 29, sharply criticizing the Trump administration's ongoing attacks on scientific research.

Those ousted were Steven Kahn, professor of medicine at the University of Washington and editor-in-chief of Diabetes Care, who co-authored the published editorial; former ADA President Desmond Schatz of the University of Florida, Gainesville; Aaron Kelly, pediatrics professor at the University of Minnesota; Justin Ryder of Northwestern University; and Irl Hirsch, also of the University of Washington. The five were handing out reprints of the editorial outside a room where NIH director Jay Bhattacharya had been scheduled to speak. Bhattacharya canceled and another NIH official spoke in his stead.

"They physically grabbed us, forced us out of the conference center, and now are telling us we can no longer attend this meeting," Kelly told MedPage Today, which first reported the incident. "They're taking our lanyards. It really has come to this in America. Censorship is real. America needs to stand up. Scientists, stand up. Physicians, stand up."
