I found the trailer for Digger intriguing, starring a nearly unrecognizable Tom Cruise and giving off strong Dr. Strangelove vibes. Plus, it is four-time Oscar-winning director Alejandro G. Iñárritu’s (Birdman) first English-language film since 2015’s The Revenant. Those elements quickly moved it near the top of my "must-see" list even if details about the actual plot were lacking. Given Iñárritu’s pedigree, the film seemed poised to be prime Oscar bait.

(Major spoilers appear below the gallery. We'll give you a heads-up when we get there.)

By now it's clear that Digger is on track to be one of the biggest bombs of the year instead, racking up a mere $20 million globally its opening weekend, against a $125 million (possibly more) budget. It has sharply polarized critics and audiences alike, with some appreciating Iñárritu's bold, creative swings and others finding the film practically unwatchable.

Francis Halzen, a physicist at the University of Wisconsin, Madison, has won the 2026 Nobel Prize in Physics "for decisive contributions to the IceCube Neutrino Observatory and the discovery of high-energy neutrinos of astrophysical origin.” Halzen spearheaded the development and construction of the IceCube Neutrino Observatory in Antarctica, enabling physicists to capture high-energy neutrinos created in the distant universe.

“It was a great surprise, and I obviously didn’t expect it,” Halzen said during a news conference in Stockholm, Sweden, speaking by phone from Italy. While the Nobel was awarded to Halzen, he emphasized that his work was the result of a “large collaboration” with other researchers.

“This reflects on the really courageous people who joined me in this project when really no respectable conservative physicist would have joined me. But many talented people did, and that’s why I’m here,” he said.

Egyptologists have long debated whether the earliest pharaohs of the First Dynasty were buried with various servants and officials to serve them in the afterlife—a form of human sacrifice. But there is very little archaeological evidence available, given that many of the earliest Egyptian tombs were plundered and/or hastily excavated. A new paper published in the journal Frontiers in Environmental Archaeology reassesses a collection of skulls excavated from tombs in the 1920s and concludes that over one-third show evidence of blunt force trauma. This suggests that they may have been victims of so-called "retainer sacrifice."

Author Roselyn Campbell is a bioarchaeologist at Purdue University who has long been fascinated with the history of human sacrifice. "I'm interested in how we as human beings decide which types of violence are okay and which are not, and how we even define violence," Campbell told Ars. "It's very context-specific. We have to be careful not to extend our own ideas about what violence is and how it's used into other cultures. With Egypt, we have such a long history of European and colonial archeology; they came in with very specific ideas about what this culture was. You really have to make an effort to contextualize the legacy data we have."

Naturally she found the debate over whether ancient Egyptians practiced retainer sacrifice pertinent to her interests. "People tend to fall into one of two camps," said Campbell. "Either retainer sacrifice definitely happened, end of discussion, or it definitely didn't happen, end of discussion. But nobody's actually looked at the bones in a very long time." Forensic science has advanced considerably over the last century, so re-analysis could be useful. Complicating matters is the fact that older sets of remains are often incomplete and/or modified for preservation, destroying vital forensic information in the process.

A wild African black panther prowls for prey. An orphaned baby pangolin must learn how to climb on its own. And a green turtle struggles to make it back to the water after laying her eggs on a remote island, rescued by local humans who carry the exhausted turtle to the water's edge. These animals and many other species are featured in Africa: Earth's Wild Home, a new documentary series from National Geographic. It's meant to launch a new franchise, with separate series documenting the wildlife and environmental ecosystems of all seven continents in turn.

The seven-episode documentary series took four years to complete, with filming taking place across nearly 30 different African countries. Each episode focuses on a specific ecosystem, from the jungle and the desert, to the plains, mountains, and islands of Africa, and closes by spotlighting the various scientists, photographers, and NatGeo explorers whose work made the series possible. The final episode focuses on the local conservation leaders and researchers working to preserve Africa's rich biodiversity for future generations.

The producers found the perfect narrator in Wunmi Mosaku, who has delivered powerful performances in such works as Sinners, Loki, and Lovecraft Country. "I was incredibly honored that they even know my name at Nat Geo," Mosaku told Ars. "It was wonderful to be asked to narrate the series. It means so much to me. As someone who was born in Nigeria and raised in England, I'll take any opportunity I can to reconnect and celebrate this incredible continent where life is so diverse and so extreme and beautiful and relentless and peaceful. I wanted to be a part of that because it's a part of me."

It’s a regrettable reality that there is never enough time to cover all the interesting scientific stories we come across. So every month, we highlight a handful of the best stories that nearly slipped through the cracks. September’s list includes a tantalizing hint of the elusive dark matter at the LUX-ZEPLIN detector; entangled Z bosons at the Large Hadron Collider; possible use of psychoactive substances in the Late Pleistocene; and an intriguing technical description of a telescope attributed to Galileo.

A hint of dark matter?

Physicists believe dark matter makes up roughly 85 percent of matter in our universe, with the strongest (but not only) candidate being so-called weakly interacting massive particles (WIMPs). But directly detecting WIMPs, or other alternative hypothetical dark matter particles, has eluded physicists for decades. We might have our first glimpse, however, courtesy of the LUX-ZEPLIN detector buried deep in a gold mine in South Dakota. Those potentially exciting results were presented in a scientific talk at the 2026 TeV Particle Astrophysics conference in Japan, with a preprint available on the arXiv. (It has been submitted to Physical Review Letters for peer review.)

The announcement came with strong caveats: the signal is just a hint, well below the threshold needed to confirm discovery, and might just be a statistical fluke. Anyone who regularly follows dark matter news knows that past tantalizing anomalies evaporated as more data came in. But the LUX-ZEPLIN team was unable to account for this event and decided to report their result to the broader physics community. They are still collecting data, as is the XENONnT at the Gran Sasso National Laboratory in Italy. And China's PandaX detector is currently being built.

With its premiere just two weeks away, Marvel Studios has dropped one last trailer for the limited series, VisionQuest, which will complete the trilogy begun with WandaVision and Agatha All Along.

(Spoilers for WandaVision and Agatha All Along below.)

As previously reported, Marvel’s streaming TV portfolio has kind of been all over the place: a handful of hits, a few misses, and a bunch of middling offerings. One standout was WandaVision, followed by an excellent sequel (of sorts), Agatha All Along. VisionQuest will complete the trilogy. Vision (Paul Bettany) died in Infinity War, but WandaVision resurrected an all-white version whose memories were restored in the finale. We finally get to learn what happened afterward.

Old-fashioned striped barbershop poles turn in place on a vertical axis, but humans typically perceive the stripes moving upward rather than turning with the pole. It's a well-known visual illusion arising from processing biases in human vision. According to a new paper published in the journal Nature, a similar effect could explain how butterflies often evade predatory birds: Their flight patterns and wing patterns combine to make it hard for predators to accurately gauge speed and direction.

"The stripes and spots on many butterflies’ wings interfere with the way visual systems try to guess the direction and speed of moving things, boosting false motion cues while hiding the butterfly's true heading," said co-author George Hancock of the University of Exeter in Cornwall. "The illusions interfere with the predator’s most basic visual targeting system and disrupt the final ‘ballistic attack’ in the tens of milliseconds when it commits to grabbing its prey, with no time to change course. As a result, birds and other predators will often simply miss."

Butterfly wings have long fascinated scientists, ever since the first documentation of the growth of said wings back in 1938. By 2021, researchers at MIT had captured on video the unique structural growth of butterfly wings—continuously, as a butterfly develops inside its chrysalis—for the very first time. Butterfly wings are an example of structural color in nature: the bright iridescent colors don’t come from pigment molecules but from what physicists call photonic crystals. The scales of chitin (a polysaccharide common to insects) are arranged like roof tiles. Essentially, they form a diffraction grating, except photonic crystals only produce certain colors, or wavelengths, of light, while a diffraction grating will produce the entire spectrum.
