Review: Carrie is a triumphant remix with one major flaw

21 October 2026 at 12:19

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.)

What did the Liberty Bell sound like? Science is on the case.

15 October 2026 at 20:10

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.

High-speed video reveals how honey bee stingers pump venom

13 October 2026 at 14:03

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.

AI disqualification yields new Nikon Small World in Motion winner

9 October 2026 at 19:44

Last month we covered the winner of Nikon's Small World in Motion video: Ning Xu of Tsinghua University in China, whose video captured tiny cilia beating in the airways of a child with a rare respiratory disorder. But allegations surfaced about Xu's use of AI while making the video. Nikon launched an investigation and concluded that Xu's entry did not comply with competition rules. The new winner is Nguyen Nam Nhat of Vietnam with a video of a tiny roundworm and a single-celled organism (above).

According to a BBC report, some researchers expressed concern that Xu's video had structural abnormalities and that cell features appeared and disappeared in a way one would not see in actual cellular biology. Others spotted what looked like AI watermarks embedded within the source files. Xu said he used AI “to distinguish and visualize features in the reconstructed grayscale images”; however, he denied that AI was used "to generate the experimental movie, the cilia, or their motion.”

Founded in 2011, the Nikon Small World in Motion competition is a spinoff of the company’s Small World Photomicrography Competition, which has been around since 1974. Both are meant “to showcase the beauty and complexity of things seen through the light microscope”—one through still photographs, the other through photovideography, taking advantage of all the technological advances that now allow users to make movies or time-lapse images through the microscope.

The other winners also moved up a notch with Xu's disqualification. Benedikt Pleyer of Bavaria, Germany, placed second with a video of jellyfish larvae suspended in water droplets; Andrew Moore of Howard Hughes Medical Institute in the US placed third with a video of synchronized cell division in neighboring cells; Patrick Hickey of Hypha Research Ltd. in Edinburgh, Scotland, placed fourth with a video of the dynamics of mitochondria and chloroplasts in Turtle Vine leaf cells; and Igor Adameyko placed fifth with a video of a tiny, colorful sea slug (Cyerce kikutarobabai) on the move.

RIP Margaret Hamilton, whose code saved the Apollo 11 Moon landing

8 October 2026 at 21:15

Margaret Hamilton, who coined the term "software engineering" and led the development of onboard flight software for NASA's Apollo program in the 1960s, died last week at the age of 90. A recipient of the Presidential Medal of Freedom in 2016, Hamilton was also immortalized as a LEGO minifig the following year—part of the "Women of NASA" set that also included astronauts Mae Jemison and Sally Ride.

“To say Margaret Hamilton was a pioneer—to say she was ahead of her time—would be a dramatic understatement. She was a software engineer at a time when that field was in its infancy, and she not only developed advanced code herself but also led a team in using that nascent technology to develop one of the most complex systems humanity had ever achieved,” said Olivier de Weck, interim head of the MIT Department of Aeronautics and Astronautics. “The Apollo program still stands as one of our greatest testaments to the power of collaboration, ingenuity, and engineering, and Hamilton was a fundamental contributor to that program’s success.”

Born in 1936 in Paoli, Indiana, Hamilton graduated from Earlham College in 1958 with a degree in mathematics and a minor in philosophy—the latter a nod to her father (a poet) and grandfather (a headmaster). She married her first husband, James Cox Hamilton, that same year. The plan was for her to work until he finished his law degree, after which he would support her through graduate school to earn a PhD in mathematics.

Scientists develop new method for deciphering ancient scrolls

16 September 2026 at 19:43

The Vesuvius Challenge is an ongoing project that combines "digital unwrapping" with crowdsourced machine learning to decipher the so-called Herculaneum scrolls, badly charred 2,000-year-old papyri too fragile to be physically unrolled. The effort just got an additional boost. A team of researchers created their own contemporary model papyrus scrolls—charring them just like the originals—to validate a screening method to determine which of the Herculaneum scrolls were written in lead-based ink and hence are the most promising candidates for further analysis. They described the process in a new paper published in the journal PLoS ONE.

As previously reported, the ancient Roman resort town of Pompeii wasn’t the only city destroyed in the catastrophic 79 AD eruption of Mount Vesuvius. Several other cities in the area, including the wealthy enclave of Herculaneum, were fried by clouds of hot gas, called pyroclastic pulses and flows. But still, some remnants of Roman wealth survived. One palatial residence in Herculaneum—believed to have once belonged to a man named Piso—contained hundreds of priceless written scrolls made from papyrus, singed into carbon by volcanic gas.

The scrolls stayed buried under volcanic mud until they were excavated in the 1700s from a single room that archaeologists believe held the personal working library of an Epicurean philosopher named Philodemus. The few opened fragments helped scholars identify various Greek philosophical texts, including On Nature by Epicurus and several by Philodemus himself, as well as a handful of Latin works. But the more than 600 rolled-up scrolls were so fragile that it was long believed they would never be readable, since even touching them could cause them to crumble.

How chimps teach their kids tool tricks

16 September 2026 at 05:00

Chimpanzees are known to use rudimentary tools when foraging for food. According to a new paper in the journal Frontiers in Psychology, this learned behavior is passed down from adults to offspring through social learning. Specifically, adult chimps deliberately model the behavior, then turn their tools over to the youngsters so they can mimic the same motions.

"Receiving food and tools from experienced individuals, which we call food or tool transfer, may help chimpanzees learn to use technology to extract foods that are difficult to access,” said co-author Andreu Sánchez-Megías, a graduate student at the University of Barcelona and the Jane Goodall Institute Spain in Senegal. “Tool transfers thus appear to be a form of teaching, together with observation and supervised practice. It appears that mothers are the main models and teachers for young chimpanzees in this manner.”

As we have previously reported, tool use was once thought to be one of the defining features of humans, although Charles Darwin observed chimpanzees using stones to crack nuts in 1871. In 1960, the late primatologist Jane Goodall observed a chimp named David Greybeard bend a twig, strip off the leaves, and use it to spoon termites out of a nest and into his mouth. When he learned of the behavior, Goodall's mentor, Louis Leakey, famously observed, “Now we must redefine ‘tool,’ redefine ‘man,’ or accept chimpanzees as humans.” Since then, chimps have been observed making sponges out of leaves to soak up liquids, shaping sticks to collect algae, and sharpening rudimentary spears for hunting.

Prehistoric builders transported Devil's Arrows 11 miles

14 September 2026 at 18:10

Stonehenge is the most famous example of megalithic architecture across Britain and Ireland, but there are plenty of others, including Calanais, Newgrange, and Avebury, as well as the Devil's Arrows. The latter is Britain's tallest standing stone alignment, yet little is known about the provenance of its stones. Scientists have confirmed that the stones came from a site 18 kilometers (11 miles) away, transported by humans rather than glacial movement, according to a paper published in the Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences.

"Sites in southern England and Scotland receive considerable attention but monuments like the Devil's Arrows have remained comparatively understudied despite their significance," said co-author Jim Leary of the University of York. "We have now proved that Neolithic communities moved several 25-ton stones across Yorkshire, transforming a familiar site into an epic quest to create a sacred landscape."

Stonehenge has been the focus of recent chemical analyses identifying where all the stones that make up the structure came from, revealing that many originated in quarries a significant distance away. For instance, a 2019 study concluded that the 42 bluestones that make up the inner ring came all the way from western Wales. The outer layer of sarsen stones hails from much closer to home: Marlborough Downs, an area of round, grassy hills 25 to 30 km (17 miles) north of Stonehenge, which has the largest concentration of sarsen in the UK.

Scientists unlock secrets of ancient Egyptian materials with proteomics

11 September 2026 at 19:49

The precise composition of ancient Egyptian paints, binders, adhesives, and similar materials used to make artifacts is largely unknown, in part because a full analysis would require taking samples that would damage those valuable artifacts. The development of cutting-edge, non-destructive techniques has been helping to unlock those secrets, aiding conservation efforts.

Most recently, researchers have used mass spectrometry-based proteomics to analyze the glues and adhesives in a broad set of Egyptian artifacts, according to a new paper published in the journal Science Advances. They found plenty of expected sources, such as animal collagens and egg proteins, but also plant proteins, specifically from sesame and drumstick tree (moringa) cereals.

As previously reported, the ancient Egyptians had a highly formalized (and easily recognizable) painting style, and there has been considerable interest in gaining insights into the specific pigments and painting techniques employed. Common pigments included hematite and realgar for red; goethite and orpiment for yellow; Egyptian blue; Egyptian green; carbon-based black; and calcite, gypsum, anhydrite, and huntite for white. (Just last year, Washington State University researchers were able to re-create Egyptian blue by mixing together silicon dioxide, copper, calcium, and sodium carbonate in varying proportions and heating them at very high temperatures akin to those of ancient kilns.)

When it comes to Beatles references, scientists can't let it be

9 September 2026 at 20:31

Scientists have an indisputable playful side, evidenced by frequent allusions to popular culture in their research publications. That includes popular song lyrics. And the most popular musical group, in terms of how frequently their songs and lyrics appear in the scientific literature, is The Beatles, according to a new paper published in the journal PLoS ONE.

“Some of these are genuinely brilliant," said co-author Gabriel Budel of Delft University of Technology in the Netherlands of the more than 3,000 references they found to The Beatles. "'The lung and winding road' is a paper on Long COVID that changes one vowel. 'Here comes the SU(N)' turns 'Here Comes the Sun' into a quantum computing paper about mathematical groups. Someone was having a very good day at their desk.”

Back in 2014, scientists at the Karolinska Institute in Sweden revealed that they had been deliberately inserting Bob Dylan lyrics into their papers as part of a long-running bet, starting with a 1997 Nature review entitled "Nitric Oxide and inflammation: The answer is blowing in the wind." That resulted in a 2015 study on whether Dylan lyrics appeared elsewhere in the biomedical literature; the most frequently referenced were "The Times They Are A'Changin'" and "Blowing in the Wind."

Prime Video releases full trailer for Mike Flanagan's Carrie

9 September 2026 at 17:40

I'm on record expressing a certain amount of skepticism about Mike Flanagan's rebooted Carrie miniseries for Prime Video. We don’t need another disappointing remake, so what story is there left to tell—especially stretched out over six episodes?

On the plus side, I'm a staunch fan of Flanagan's excellent Netflix horror fare, and he has a particular affinity for the works of Stephen King. He insists he has no intention of creating yet another straight adaptation of the novel.

“Carrie was written half a century ago,” Flanagan said at San Diego Comic-Con earlier this year. “Carrie was adapted spectacularly by Brian De Palma. It is iconic. It is untouchable. There is no reason whatsoever to try to follow in those footsteps and to try to walk on that path. However, the world has changed quite a lot. I think a lot of people think they know what the show is. And the biggest thing I’m excited about today is just knowing what a big surprise our Carrie is going to be.”

Godzilla Minus Zero IMAX trailer teases King Ghidorah

8 September 2026 at 19:53

One of the cinematic highlights of 2023 was director Takashi Yamazaki's gloriously grounded kaiju epic, Godzilla Minus One, which became a major international hit and snagged an Oscar for best visual effects. Yamazaki is back this fall with the hotly anticipated sequel, Godzilla Minus Zero. Toho just dropped the full IMAX trailer, featuring not just our beloved Godzilla, but also a distinctive roar that teases the appearance of none other than the three-headed King Ghidorah.

(Spoilers for the 2023 film below.)

Godzilla Minus One focused on kamikaze pilot Kōichi Shikishima, who struggled with survivor's guilt after he failed to take action when Godzilla attacked the Japanese base on Odo Island in 1945. Knocked unconscious, Kōichi woke to find he was one of only two survivors—and the other, a mechanic named Tachibana, was furious about it. His parents and many others were killed in the World War II bombing of Tokyo. Kōichi rebuilt a life with a woman named Noriko and the orphaned baby she rescued, Akiko. But then Godzilla re-emerged, and Kōichi resolved to die fighting the monster to atone for Odo Island.

The secret to protecting next-gen spacecraft might be eggshells

8 September 2026 at 17:20

In 2007, a piece of space debris punched a bullet-like hole through the radiator panel of the US space shuttle Endeavor. The shuttle program ended in 2011, but the space debris problem has only intensified as we launch more and more satellite constellations, telescopes, and spacecraft into orbit. That's why Chinese scientists have devised a new aluminum material inspired by eggshells that they believe could offer enhanced protection against debris fragments, according to a new paper published in the Journal of Applied Physics.

Eggshells have long fascinated scientists because of their mechanical properties. For instance, it's well known that cracking an egg requires applying just enough force to the center to achieve a clean break without completely shattering the shell. In 2012, MIT mechanical engineer Pedro Reis co-authored a paper demonstrating the link between an egg's ovoid geometry and its rigidity, a major factor when predicting how much force an object can endure before cracking. (As I wrote for Slate at the time, rigidity is related to, but distinct from, strength. If one eggshell has tiny cracks and the other doesn't, both shells have different strengths—the cracked one will break more easily—but the same rigidity.)

Reis started studying eggshells after participating in a popular physics demonstration: walking on cartons of eggs without breaking them. The key, he learned, was to align the eggs with their narrow tip (the most crack-resistant part) pointing up, and then carefully place one's feet to distribute one's weight over the entire surface area. This ensures that no single egg is overloaded. While it takes around 5.5 pounds of force to crack an egg, that depends on the direction in which the force is applied, as well as its distribution over the shell's surface.
