  • ‘Casper’ Is Weirder and Darker Than You Remember

    ‘Casper’ Is Weirder and Darker Than You Remember

    In 1995, the most famous Harvey Comics character not named Richie Rich made his live-action big-screen debut, though the Casper we see throughout his self-titled movie is brought to life mostly through the best CGI money could buy 30 years ago. With Steven Spielberg producing, a post-Addams Family Christina Ricci starring, an excessive amount of cameos, and a plot that addresses death in ways both tragic and silly, Casper crafts a tone that would be unique to any supernatural fantasy. But it’s especially oddball in a movie ostensibly aimed at children.

    The directorial debut of Brad Silberling, Casper first hit theaters May 26, 1995, and it was a smash hit, ending up the eighth-highest grossing film of the year (sandwiched between Seven and Waterworld). The biggest kids’ movie of 1995 was Toy Story, which does dig into some existential themes, but doesn’t face the void quite as boldly as Casper does. 

    It begins with a death, as the greedy Carrigan Crittenden (Cathy Moriarty) and her sleazy attorney Dibs (Eric Idle) learn she’s inherited just one thing from her recently departed father, who she’s clearly not mourning whatsoever: Whipstaff Manor. Carrigan has no use for the dilapidated seaside mansion—located in the optimistically named Friendship, Maine—until a paper tucked in with the deed gives her and Dibs the notion that there’s treasure hidden somewhere within.

    Elsewhere in the story, another death has shaped a different set of characters: Dr. James Harvey (Bill Pullman, in a career sweet spot after Sleepless in Seattle and While You Were Sleeping, and just ahead of Independence Day and Lost Highway) and his daughter Kat (Ricci, who soon after began to shift away from kid-oriented roles). Harvey and Kat are still grieving the loss of Kat’s mother; Harvey’s coping mechanism has been to fashion himself into a sort of touchy-feeling exorcist, using his therapy skills to help guide “living impaired” patients into the beyond. 

    Beneath that, of course, lurks his hope that he’ll be able to contact his late wife in the great beyond—something Kat puts up with despite being teased about her kooky dad. Harvey promises her that this will be the very last time he uproots his daughter for a ghost hunting gig when they pull up to Whipstaff Manor. As Carrigan and Dibs have discovered, the place is haunted by ghosts so stubborn neither a priest (comedian Don Novello as his long-running character Father Guido Sarducci) nor a Ghostbuster (Dan Aykroyd, in full Ray Stantz mode) can get them out. 

    It’s a good thing Casper was released by a different studio than Beetlejuice, because things could’ve gotten really messy there. Instead, we get the newly hired Harvey facing off with (and eventually befriending, though it takes awhile) the Ghostly Trio (Brad Garrett as Fatso, Joe Nipote as Stretch, and Joe Alaskey as Stinkie). The lonely Kat—who attracts bullies even in Friendship, Maine—finds herself bonding with the trio’s nephew, Casper (Malachi Pearson), the Friendly Ghost who’s sadly very friendless.

    Except, Casper doesn’t want to be just friends with Kat, does he? Early in the movie Casper travels through electrical lines and zaps his way into Carrigan’s hotel room; there, he ensures she sees a TV program focusing on Harvey, just the expert she needs to deal with her spectral problem. Casper does this because he’s seen the same segment, which features a glimpse of Kat so arresting it makes the ghost of a 12-year-old boy swoon—then scheme to get her into his house.

    Kat doesn’t know it’s Casper’s old bedroom when she picks her spot in Whipstaff Manor. Nor does she overhear his delight (“There’s a girl on my bed… yesss!”), which would feel more innocent and cute if there weren’t some other unwholesome come-ons later in the movie. That includes the infamous moment when Casper kisses a sleeping Kat after murmuring “Can I keep you?” 

    That cringey line is repeated at the end of the film when Casper briefly gets to be a real boy (played by future horror icon Devon Sawa). Though Kat is thrilled by his corporeal appearance, and his voice is far less squeaky when he’s in human form, “Can I keep you?” still makes her look askance.

    As soon as Casper becomes a ghost again, he’s immediately back in the friend zone, a feeling further underlined by the contrast between Sawa’s teen-dream appearance and Casper’s cartoonish visage. The movie, which has also just given Harvey a sweet if fleeting reunion with his angelic dead wife, goes for a feel-good finale with the Spooky Trio—who indulge in innuendo-laden humor throughout the movie that’s presumably aimed at any adults watching—rocking out to Little Richard’s “Casper the Friendly Ghost” theme as Kat and her father dance.

    Less happy endings are handed down to Kat’s junior high foes, who are sent screaming away from the climactic Halloween party at Whipstaff after encountering Casper’s uncles, as well as Carrigan and Dibs, who perish while trying to get their mitts on the “treasure,” which turns out to be an autographed baseball. Carrigan, at least, briefly becomes a ghost who inadvertently ties up all her unfinished business when she finds the baseball. Screaming in protest, she gets booted into the afterlife as a result. (Dibs gets tossed through a window and out of the movie for good.)

    The idea that ghosts who resolve their unfinished business are allowed to move on, which is pretty standard supernatural lore, makes Casper’s situation all the more perplexing. In the movie, we learn he became ill and died after playing too long in the snow—then decided to hang around to keep his sorrowful father company. (When Kat asks him what it’s like to die, he grimly describes it as “like being born, only backwards.”)

    In turn, the eccentric inventor created a “Lazarus machine” specifically to bring his beloved son back to life. (As Gremlins showed us as well, there’s nothing an Amblin movie loves more than a dad who’s also a chaotic inventor.) It’s still in Whipstaff’s basement and still functional, with just enough juice to revive Harvey after he perishes in an accidental fall.

    This raises some questions, namely: why didn’t Casper’s father go ahead and revive him back then? Thanks to a vintage newspaper we learn that he was eventually carted off to the psychiatric hospital because of his “bring ghosts back to life” obsession, but the Lazarus Machine is very well hidden in a secret room. Surely he would have had enough time to resurrect Casper before anyone found out?

    The answer, presumably, is that we need Casper to be a ghost for there to be Casper, and for all the elements jerry-rigged around that central point, it’s surprising there aren’t more plot holes. Kat’s party dress, which once belonged to Casper’s mother, is pulled from a trunk and donned over a full outfit of other clothes, which then seemingly disappear on their own and the costume’s a perfect fit? Don’t worry about it. What will happen to Kat and Harvey’s living situation now that Whipstaff’s new owner has fled this mortal coil? Again, don’t worry about it. Are the Spooky Trio ghosts actually Casper’s uncles, as they are in the comics, or are they three unrelated dead guys who’ve taken up residence and routinely order the little guy to serve them platters of junk food? 

    Also, though we did poke fun at the special effects’ 1995-ness earlier, they actually look pretty great considering how much the ghost characters have to interact with the human ones. Going cartoony not only keeps Casper and crew looking like their comic-book counterparts, it also keeps what passes for menace in this movie on the gentler side. There’s also a weird comedic disconnect when you realize Harvey has died—a sad moment for the suddenly orphaned Kat—and is now… a goofy-looking phantom instead.

    Casper’s popularity spawned a few straight-to-video prequel-sequels and a cartoon series, but somehow has never made it back to the big screen. While that seems unlikely after all this time, a live-action Casper series unconnected to the movie has been in development at Peacock for the past few years. But wherever Casper—who first appeared in November 1945, so happy 80th, buddy—rises from the grave next, we can always keep this 30-year-old, enduringly entertaining oddity.

  • 10 Games Milked for All Their Worth

    10 Games Milked for All Their Worth

    Sticking with what works is nothing new, especially in gaming. New stories, characters, and mechanics are increasingly rare. Long development times and ballooning budgets only compound the issue, as studios must take a larger gamble with every project. Why take that risk when going with a guaranteed success is safer?

    That mindset prompts developers to exploit certain games to no end. They don’t just make sequels. Rather, when studios stumble on a hit, they refuse to move on before milking it dry. In such cases, a single game can spawn remakes, remasters, ports, expansions, spin-offs, and adaptations. Granted, revisiting a beloved tale is a comforting experience, as it lets audiences bask in those familiar feelings and remember why the work resonated with them in the first place. Then again, repeating this strategy can have the opposite effect. With enough exposure, even the most ardent fans may get sick of their old favorites. It’s ultimately up to those fans to decide their breaking point.

    10 The Last of Us

    Zombie apocalypse tales were already plentiful before The Last of Us, but none matched this game’s runaway success. The title revolved around a broken man named Joel, whose daughter died in the initial outbreak. After several years as a mercenary, he got a job transporting an immune girl called Ellie across the U.S. Their shared struggles eventually brought them closer, letting them regain some sense of family in a ruined world. That father-daughter dynamic fueled the game for years to come.

    The Last of Us transcended both its genre and its console. Though initially a PS3 exclusive, it quickly got a remastered edition for PS4. These releases coincided with comic prequels, tabletop games, live readings from the cast, and theme park rides. Over the years, other consoles got ports of the remastered version leading up to the eventual sequel, The Last of Us Part II. Even after this follow-up, the developers remade the original entry, releasing it yet again as The Last of Us Part I. This remake immediately preceded a TV adaptation on HBO. Clearly, fans will never see the last of The Last of Us.[1]

    9 The Elder Scrolls V: Skyrim

    The Elder Scrolls was always popular with the role-playing crowd, but the fifth entry brought it to the mainstream. The Elder Scrolls V: Skyrim placed fans in a Nordic fantasy realm. Here, they functioned as the Dragonborn: a prophesied warrior who absorbed dragon souls and channeled their magic in explosive shouts. They could go anywhere and do anything, exploring the rich world and influencing pivotal events with their nuanced actions. That open-ended appeal was too addictive for its own good.

    Skyrim kept its company afloat for over a decade. Just two years after its initial release came the Legendary Edition with all three DLC packs. The next console generation saw the remastered Special Edition, which additionally came to the Nintendo Switch. After these releases, there was a virtual reality edition, aptly titled Skyrim VR. Finally, the game’s 10-year popularity prompted the Anniversary Edition, packaging the previous DLCs with a wealth of new content from both players and developers. It’s easy to see how fans spent hundreds of hours in this mythical wonderland.[2]

    8 The Witcher 3: Wild Hunt

    After a gradual path to the mainstream, this fantasy franchise saw a massive hit with The Witcher 3: Wild Hunt. The threequel saw the monster-hunting Geralt on a search for his adopted daughter, Ciri, whose world-hopping powers made her a target for a sinister band of spectral marauders. Arguably more engaging, though, were the countless hours of exploring the realm, taking on quests, and enjoying every painstaking detail. That adventure attracted legions of genre fans.

    The widespread reach caused developers to take note. The two huge expansions—practically full games themselves—led to later releases like the Complete Edition and the Game of the Year Edition. These versions came with all the extra tweaks, fixes, and content. The subsequent Netflix series only furthered that esteem. Though based on the books instead of the games, it prompted yet more players, which drove developers to add a few of its aspects to The Witcher 3. The studio then incorporated these fixings into a next-gen remaster for new systems. All this doesn’t even account for the title’s card game, Gwent, which got several spin-offs incorporating the books’ lore. The developers’ passion for this property knows bounds.[3]

    7 Final Fantasy VII

    Each mainline Final Fantasy game was a fresh story in a new world, but one entry defied that tradition time and time again. Final Fantasy VII began with the evil Shinra corporation sapping the planet’s magical energy for its deranged goals. These schemes inadvertently brought disaster, ironically spurred on by the company’s greatest warrior/experiment, Sephiroth. The only hope lay with a ragtag group of heroes led by a former Shinra trooper named Cloud Strife. Only by solving the planet’s age-old mysteries and harnessing its energy could they save it from calamity. That rich mythology and intuitive gameplay shot FFVII to the series’ top tier.

    It’s not surprising, then, that it’s received the most attention post-release. On top of porting the classic to other consoles, the developers expanded the world through various spin-offs, prequels, and sequels. They included tales like Advent Children, Crisis Core, and Dirge of Cerberus. In addition, the Kingdom Hearts series featured FFVII characters in recurring guest appearances. This continuing fanfare culminated in the Final Fantasy VII Remake trilogy, which recreated the original tale with updated graphics, voice acting, and a new combat system. The creators will soon become as greedy as Shinra.[4]

    6 Dragon Ball Xenoverse 2

    In the vast catalog of Dragon Ball tie-ins, Xenoverse 2 stuck around the longest. It lets players create a custom character and travel through the franchise’s history, affecting pivotal events by fighting alongside the heroes. Developing one’s character hinged on learning from these heroes (or villains). You then pitted those skills against other players in online matches. That continued fan support was what kept the game going.

    Xenoverse 2 has steadily added features for a decade. Part of the demand stemmed from the expanding brand. Dragon Ball Super and Dragon Ball Daima aired during the game’s lifecycle, thereby drumming up enthusiasm and providing a consistent source for new DLCs. On top of these additions, fans contributed their own creations through mods. All 40 years of Dragon Ball history gradually gathered into this single title.[5]

    5 Resident Evil

    In contrast to its overblown successors, the first Resident Evil was a small-scale affair. The tale involved members of a special task force trying to escape a zombie-filled manor. That goal was a slow burn as they carefully navigated the hazardous place while solving puzzles, gathering resources, and avoiding monsters. Clunky controls aside, the patiently horrific atmosphere and meticulous mechanics made for an immersive survival experience, especially compared to what came after. That hindsight likely fueled the game’s many returns.

    The developers sought to recapture Resident Evil’s magic without the frustration. Though originally limited to PlayStation, it soon came to PC and Sega Saturn, each boasting a handful of fresh features. However, the classic quickly returned to PS1 with the Director’s Cut: a slightly adjusted version with new outfits, animations, modes, and item locations. This package itself got a variation called the Dual Shock Ver., which updated the music and supported the recent DualShock controller. Following this were a GameCube remake and a Nintendo DS port. These releases sported yet more modifications in gameplay and aesthetics. Throw in the blockbuster movie series, and fans couldn’t forget this horror story if they tried.[6]

    4 Persona 3

    The Persona series is no stranger to re-releases, but Persona 3 got the most attention in this area. Like its peers, the RPG revolved around Japanese schoolchildren. Going about their daily routines, they found their city under attack from shadowy monsters, which they fought using the series’ trademark turn-based combat. The gameplay loop was as dense as ever, but the developers stuffed it still further.

    This title received a re-release for seemingly every new feature. Persona 3 FES extended the playtime and added a harder difficulty option; this version became available on subsequent consoles through retro ports. On the other hand, the PSP saw its own rendition with Persona 3 Portable . This title condensed the experience into a visual novel, adjusted the narrative, and revamped the mechanics with Persona 4 as a template. Finally, fans got a full-blown remake in Persona 3 Reload , with all the benefits of modern hardware and recent entries. The tale’s child stars should be seasoned adults by now.[7]

    3 Half-Life

    Half-Life mirrored Resident Evil in both narrative and history. Players controlled a scientist as he raced to escape a research station infested with aliens. Although the foundation was a first-person shooter, the game heightened the tension through its maze-like structure and a lack of scripted sequences. The refusal to hold players’ hands resonated, and they certainly showed their gratitude over the years.

    Half-Life was another classic nurtured by both developers and fans. The former followed the initial release with expansions like Opposing Force, Blue Shift, and Decay. These packs retold the story with new characters and multiplayer functionality. Plus, they went into subsequent ports on PS2, OS X, Linux, and the Source engine. On the fan side of things, modders used Half-Life’s assets to craft separate titles like Counter-Strike and Day of Defeat. These efforts culminated in a complete remake called Black Mesa. Suffice it to say—Half-Life’s half-life was longer than anticipated.[8]

    2 Grand Theft Auto V

    The Grand Theft Auto games popularized open-world chaos, with this pivotal entry taking it to the extreme. *Grand Theft Auto V* juggled three contrasting protagonists as they pulled off daring heists, often amid crooked government oversight and rival gangs. On top of the story’s insanity, players got a kick out of Los Santos, a massive sandbox with a plethora of pastimes. The resulting hype lasted long after its debut.

    GTAV enjoyed endless exposure post-release. A year after it first hit PS3 and Xbox 360, the game got a remaster for PS4, Xbox One, and PC. This version came with technical improvements and added gimmicks like first-person mode. Further tweaks came in the following generation with an Expanded & Enhanced version on PS5 and Xbox Series X. Meanwhile, developers continued the content with Grand Theft Auto Online, which used GTAV’s open world for a handful of multiplayer modes. Only after a decade did they leave that world behind. This money-making scheme put the biggest heists to shame.[9]

    1 Pokémon Red & Blue

    The pocket monster series has seen an obscene number of entries, but they all stood on the first generation’s shoulders. The original pair of Pokémon games—Red and Blue Version—challenged players to assemble an elite team. Journeying across the land, they caught and trained Pokémon of various types. They then pitted these creatures against other trainers, earned eight badges by beating corresponding gym leaders, and bested the Pokémon League to take the region’s top spot. That simple yet irresistible formula drove multiple generations, but the developers didn’t forget their roots.

    The initial Pokémon journey reappeared several times throughout the franchise. Shortly after its debut came Yellow Version: a re-release to resemble the popular anime series, complete with a Pikachu companion. The subsequent Gold, Silver, and Crystal versions also looked backward. Although these games mainly showcased a new setting, they also let players revisit the first generation’s Kanto region and relive the classic journey once again. As if that wasn’t enough, the developers later remade the titles twice: FireRed and LeafGreen for the Game Boy Advance and Let’s Go, Pikachu! and Let’s Go, Eevee! for the Switch. Gotta play ’em all![10]

  • Doctors Warn That Bringing Your Phone to the Bathroom Could Backfire in a Painful Way

    Doctors Warn That Bringing Your Phone to the Bathroom Could Backfire in a Painful Way

    At the annual Digestive Diseases Week conference in San Diego this May, Dr. Trisha Satya Pasricha of Beth Israel Deaconess Medical Center presented the results of a small but striking survey: people who bring their smartphones with them to the toilet may face a 46% higher risk of developing hemorrhoids.

    Yes, hemorrhoids — those painful, swollen veins in the lower rectum that affect millions — may have a new accomplice: your phone.

    Doomscrolling on the toilet. Image generated using Sora/ChatGPT

    A New Kind of Bathroom Reader

    The study surveyed 125 people undergoing colonoscopies. Each participant was asked about their bathroom habits, especially whether they used their phone while on the toilet.

    The results were telling. Over 93% said they used their phones on the toilet at least once a week. Of that group, roughly half scrolled through news, 44% browsed social media, and about 30% were texting or emailing.

    Some respondents admitted to lingering on the toilet for over six minutes per visit — far longer than the time most doctors recommend. Many believed their smartphone use was the reason.

    Smartphones are incredibly engaging, and that engagement may be extending our toilet time. While the study is observational and cannot prove causation, it adds weight to growing concerns over how digital distractions are subtly reshaping our biology. About 40% of the participants had hemorrhoids. This rate was significantly higher among regular phone users.

    Hemorrhoids 101

    In the United States, hemorrhoids are responsible for nearly 4 million medical visits each year. And yet, this condition — as common as it is uncomfortable — remains surprisingly under-researched.

    The last national survey on hemorrhoid prevalence was conducted in 1989. Since then, most data have come from fragmented reports and small studies like this one.

    We do know that hemorrhoids aren’t abnormal in themselves. In fact, everyone has them. They’re vascular cushions that help maintain continence and ease the passage of stool. The trouble begins when these cushions swell or bleed, causing pain, itching, or a palpable bulge.

    The leading theories on what causes them often focus on pressure — from straining during bowel movements, prolonged sitting, or chronic constipation. Sitting too long on the toilet, especially with a bent-forward posture, may place undue strain on the rectal veins.

    Phones, researchers now suggest, may be the latest addition to this list of risk factors. Not because they are inherently harmful, but because they change our behavior. The more engaged we are on the toilet, the longer we stay.

    Previous studies hinted at this link. One found that patients with hemorrhoids spent more time reading in the bathroom than those without. But that was back when people read magazines or newspapers. Now, smartphones offer infinite content — algorithms engineered to hold our attention, even on the ‘throne’.

    What Can You Do?

    Some experts advise that toilet time should be kept under 10 minutes. Others suggest an even tighter window: no more than 3.

    There’s a growing chorus calling for a return to single-minded toileting. A 2024 research team went as far as to say, “It may be time to designate the washroom as a smartphone-free zone.”

    After all, phones have crept into almost every corner of our lives. Bringing them into the bathroom may simply be one intrusion too far — for our minds and bodies.

    For now, the message is simple: keep your phone out of the bathroom, and your bathroom visits short. As ScienceAlert wrote, “Going number two should be your number one priority – not scrolling on your phone.”

    So next time nature calls, try not answering with your phone.

  • These Infrared Night-Vision Contacts Let You See Through Your Eyelids

    These Infrared Night-Vision Contacts Let You See Through Your Eyelids

    In a move straight out of a sci-fi movie, scientists have created wearable infrared contact lenses that allow you to see in the dark, even with your eyes closed.

    A group of scientists from the University of Science and Technology of China unveiled the lenses in a study published today in Cell.

    Unlike infrared goggles, these contact lenses don’t require a power source. Instead, they convert infrared light to visible light using nanoparticles. The ten lucky human participants who tried on these contact lenses could perceive otherwise imperceptible infrared wavelengths, according to the study.

    The scientists are already thinking about futuristic applications of the contact lenses. “Our research opens up the potential for non-invasive wearable devices to give people super-vision,” said Tian Xue, a neuroscientist at the University of Science and Technology of China and the senior author of the study in a statement to Cell Press. “There are many potential applications right away for this material. For example, flickering infrared light could be used to transmit information in security, rescue, encryption or anti-counterfeiting settings.”

    The contact lenses use upconverting nanoparticles—teeny tiny particles that absorb multiple low energy photons and emit a single, high-energy photon. Specifically, these particles absorb lower-energy near-infrared wavelengths (800-1600 nm range) and convert it to wavelengths that are visible to mammalian eyes (400–700 nm range). The researchers had already demonstrated that they could enable infrared vision in mice by injecting particles into the retina, but they wanted to develop a method that didn’t require you to inject anything directly into your eyeballs.

    So, the researchers combined the nanoparticles with polymers that are used in normal soft contact lenses.

    The scientists first tested a much smaller version of these contacts on mice, finding that the mice behaved as if they could see infrared wavelengths. Taking advantage of the fact that mice prefer to hide in dark crevices, the researchers gave the mice a choice between a dark box or a box illuminated with infrared light. Without the contacts, mice showed no preference between the dark box and the illuminated box. But with the contacts, the mice were more likely to choose the dark box.

    The researchers then recruited human participants to try out the lenses. The scientists found that people wearing the lenses could detect morse code-like flashes and perceive the direction of incoming infrared light from an LED. “It’s totally clear cut: without the contact lenses, the subject cannot see anything, but when they put them on, they can clearly see the flickering of the infrared light,” Xue said in a statement. “We also found that when the subject closes their eyes, they’re even better able to receive this flickering information, because near-infrared light penetrates the eyelid more effectively than visible light, so there is less interference from visible light.” They also saw this light better with their eyes closed.

    The researchers also modified the contact lenses to allow participants to distinguish between different wavelengths of infrared light. They made a version of the lenses that convert different spectra of infrared light to specific visual wavelengths—980 nm was converted to blue light, 808 to red light, and so on.

    But before you get too excited, though, it’s important to note that participants wearing the lenses couldn’t see all that well. They weren’t able to make out fine details of their environment, for example, and could only see infrared light coming from an LED. This is because the contact lenses scatter the incoming infrared light, the authors wrote.

    To combat this, the researchers created wearable eyeglasses using the same basic principles. This helped a little bit, and participants were able to distinguish infrared patterns and shapes, but still weren’t able to see ambient infrared light.

    The technology isn’t quite at super-vision levels yet, and scientists are working on making these contacts more sensitive. “In the future, by working together with materials scientists and optical experts, we hope to make a contact lens with more precise spatial resolution and higher sensitivity,” Xue said in a statement.

  • 10 Ancient “Smart” Materials Scientists Still Can’t Reproduce

    10 Ancient “Smart” Materials Scientists Still Can’t Reproduce

    As civilizations from Rome to the Maya harnessed empirical ingenuity to create materials with built-in healing, color-shifting, or structural resilience, they left behind recipes that modern science is only now decoding. From rust-proof iron pillars and self-repairing concrete to nanotech-level glass and ancient vulcanized rubber, these ten remarkable “smart” materials demonstrate how our ancestors engineered solutions that still inspire today’s cutting-edge research.

    10 Roman Self-Healing Concrete

    The secret behind the longevity of Roman maritime structures lies in a precise combination of volcanic ash (pozzolana), lime, and seawater, creating a hydraulic binder that sets underwater. When tiny fissures form, they allow seawater to infiltrate the mortar, dissolving calcium hydroxide and unreacted lime particles. These dissolved minerals then react with silica and alumina from the volcanic ash to precipitate aluminum tobermorite crystals within the cracks. Detailed petrographic analyses of cores taken from the Roman piers at Pozzuoli Bay have revealed layers of tobermorite up to 150 micrometers thick, effectively sealing cracks over decades. Modern X-ray diffraction and scanning electron microscopy studies confirm that this autogenous healing process continues long after initial curing.

    Researchers at MIT’s Department of Civil and Environmental Engineering and the University of Toronto’s Department of Materials Science are reproducing this mechanism by embedding ureolytic bacteria (Sporosarcina pasteurii) or encapsulated mineral precursors (calcium lactate microcapsules) into contemporary concrete mixes. When microcracks allow water ingress, the bacteria hydrolyze urea to produce carbonate ions, which combine with calcium to form calcite, sealing fissures up to 0.5 mm wide. Large-scale field trials on highway bridges are underway to quantify long-term durability improvements and to compare the energy footprint of biologically active concrete versus traditional repair cycles.[1]

    9 Wootz (Damascus) Steel

    Originating in South India as early as the 3rd century BCE, Wootz steel was traded globally and forged into the legendary Damascus blades admired for their combination of razor-sharp edges and exceptional toughness. Chemical analysis of surviving Wootz ingots and blades—using transmission electron microscopy and atom probe tomography—has identified networks of carbide nanoparticles enriched in vanadium and molybdenum at grain boundaries, which impede crack propagation. Periodic thermal cycling and repeated folding during forging created a banded microstructure: alternating layers of hard cementite and softer ferrite phases.

    Contemporary metallurgists at the University of Manchester’s Henry Royce Institute and Tohoku University’s Institute for Materials Research are exploring powder metallurgy and laser additive manufacturing techniques to recreate these features. By controlling cooling rates to within 1 °C per second and introducing trace vanadium at concentrations as low as 0.03%, they have produced experimental blades exhibiting hardness values above 65 HRC and Charpy impact toughness comparable to historical artifacts. Collaborations with archaeometallurgists are refining thermal-tempering schedules based on differential scanning calorimetry data from authenticated Wootz samples.[2]

    8 The Lycurgus Cup’s Dichroic Glass

    Crafted in the 4th century CE, the Lycurgus Cup remains an unparalleled example of ancient nanotechnology. The goblet’s silica matrix contains embedded gold and silver nanoparticles, typically 15–25 nanometers in diameter, that interact with visible light via localized surface plasmon resonance. In reflected light, shorter wavelengths are predominantly scattered, giving the cup a jade-green appearance; in transmitted light, longer red wavelengths pass through, rendering a translucent ruby-red hue. Synchrotron-based X-ray absorption spectroscopy has precisely mapped the ratio of gold to silver, revealing 5:1 proportions concentrated near the inner surface where nanoparticle density is highest.

    Current efforts in photonic materials research at Harvard SEAS involve synthesizing sol-gel glass matrices with tunable metal-nanoparticle distributions. By adjusting reduction potentials during chemical vapor deposition, engineers achieve narrow particle-size distributions within 1–2 nanometers variance. These advanced dichroic films are being tested as anti-counterfeiting overlays for currency and corporate securities. Larger-scale fabrication trials are also exploring dynamic window coatings that adaptively alter color balance in response to sunlight intensity, potentially reducing building cooling loads by up to 12%.[3]

    7 Egyptian Faience

    Egyptian faience—far older than glazed ceramics—relies on a quartz (silica) core mixed with alkali fluxes (natron or plant ash) and copper-based colorants. During firing at temperatures between 1,472°F and 1,742°F (800°C and 950°C), a thin layer of the surface liquefies, forming a self-glazed vitreous coating rich in copper silicates that produce characteristic turquoise and deep blue hues. Microprobe analysis of artifacts from Abydos shows copper concentrations of 4–7% by weight in the glaze layer, with an interfacial transition zone where silica gradually increases from 60% to over 80%. Controlled-atmosphere kilns recreated in lab settings demonstrate that minor variations in oxygen partial pressure (from 0.01 to 0.03 atm) significantly shift glaze opacity and color saturation.

    Chemists at the Getty Conservation Institute are using laser-induced breakdown spectroscopy to monitor in-situ glaze formation and to identify optimal firing profiles that minimize kiln defects. Their goal is to develop environmentally friendly flux alternatives—such as sodium-potassium borates—reducing reliance on mined natron. Additionally, exploring microscale layering techniques has led to prototype tiles with graded color zones, replicating ancient faience’s natural gradient effects for modern architectural and artistic applications.[4]

    6 Maya Blue Pigment

    Celebrated for its vibrancy and resilience in tropical conditions, Maya Blue results from indigo molecules encapsulated in the channel structure of palygorskite clay. When mixtures of finely ground indigofera leaves and palygorskite are heated to 248–302°F (120–150°C) for 1–2 hours, indigo bonds via hydrogen and van der Waals interactions to silanol groups lining the clay’s tubular channels. Synchrotron X-ray diffraction studies reveal that approximately 0.7 molecules of indigo occupy each unit cell of palygorskite, creating a hybrid organic–inorganic pigment that resists acids, alkalis, and microbial degradation.

    At UCSB’s Materials Research Laboratory and UNAM’s Institute of Materials Research, scientists employ infrared spectroscopy and thermogravimetric analysis to optimize low-temperature binding protocols that prevent indigo decomposition. Their work has yielded synthetic Maya Blue variants incorporating other natural dyes—such as carmine and weld—to produce a spectrum of durable pigments for conservation-grade paints and inks. Ongoing field tests on historical building facades in Mexico are evaluating weathering performance over multi-year exposures to UV radiation and acid rain.[5]

    5 The Iron Pillar of Delhi

    Erected around AD 400 in the temple complex of Qutub Minar, the 23-foot (7-meter) tall, 6-ton Iron Pillar of Delhi remains remarkably rust-free despite exposure to monsoon rains. The artifact’s purity—iron content exceeding 98%, phosphorus levels around 0.25–0.30%, and negligible sulfur or manganese—encouraged formation of a passive oxide film. Analytical studies using X-ray photoelectron spectroscopy have identified a 10–15 µm thick misawite (δ-FeOOH) layer that adheres tightly to the metal, preventing oxygen infiltration and further corrosion.

    Materials scientists at the Indian Institute of Science and the National Physical Laboratory in India replicate this ancient alloy via bloomery-smelting processes, adjusting bog iron feedstock phosphorus content. Their accelerated weathering tests—subjecting replicas to cyclic salt-spray and humidity conditions—demonstrate corrosion rates less than 0.01 mm/year, outperforming comparable modern steels in marine environments. These findings inform development of low-alloy, high-phosphorus steels for coastal infrastructure that mimic the Iron Pillar’s self-protective characteristics.[6]

    4 Chinese Imperial Porcelain

    By the Tang Dynasty (7th–10th centuries AD) and reaching zenith under Song and Ming rule, Chinese kilns in Jingdezhen produced porcelain so pure that it transmitted light when thinly cast and rang like a bell when tapped. The body comprised 70–75% kaolin clay for plasticity and 25–30% petuntse (feldspathic rock) for vitrification, fired at temperatures exceeding 2,372°F (1,300 °C) in oxidizing atmospheres. Laser-induced breakdown spectroscopy and electron microprobe analyses of shard cross-sections reveal uniform grain sizes below 2 µm and minimal microcracking, contributing to translucency and mechanical strength.

    Modern ceramists at the Imperial Kiln Museum and Tsinghua University apply programmable electric kilns with precise ramp rates (up to 50°F or 10 °C/min) to replicate Ming-era glazes containing trace manganese and iron impurities. Their work has led to advanced zirconia-reinforced porcelain composites with fracture toughness values above 4 MPa·m½ and thermal shock resistance suitable for aerospace components. Additionally, insights into ancient firing–cooling profiles guide the manufacture of orthopaedic implants with bioinert surfaces and tailored porosity.[7]

    3 Mesoamerican Vulcanized Rubber

    Long before Goodyear’s 19th-century breakthrough, the Olmecs and Maya mixed latex from Castilla elastica trees with sap from morning-glory vines (Ipomoea alba), whose organic sulfur compounds initiated cross-linking. Gas chromatography–mass spectrometry of ceremonial ball fragments reveals sulfurated organic moieties at 1–2% wt, sufficient to create covalent C–S bonds between polyisoprene chains. This primitive vulcanization enhanced elasticity and thermal stability, maintaining mechanical integrity across 68–104°F (20–40°C) diurnal swings.

    Researchers at the University of Akron’s Polymer Science Center are reverse-engineering these ancient recipes, using thermogravimetric analysis to map curing kinetics and dynamic mechanical analysis to measure storage—and loss moduli—over frequency sweeps. Their bio-based elastomer prototypes incorporate plant-derived sulfur donors and natural antioxidants, exhibiting tensile strengths above 15 MPa and self-healing properties when reheated to 140°F (60°C). Applications include eco-friendly gaskets and seals for green energy systems.[8]

    2 Inca Seismic-Proof Stone Masonry

    At sites such as Sacsayhuamán and Machu Picchu, Inca stonemasons carved granite and andesite blocks with convex faces and interlocking joints, achieving assembly tolerances under 1–2 mm. Finite-element modeling of wall segments shows that under simulated 7.5-magnitude earthquakes, blocks pivot and settle laterally by up to 3 mm, dissipating seismic energy without structural failure. Surface polishing techniques removed microasperities, ensuring even contact pressure and eliminating stress concentrators.

    Engineers at the University of Cambridge’s Centre for Smart Infrastructure and Rensselaer Polytechnic Institute use laser scanning and photogrammetry to capture joint geometries, then employ robotic milling to fabricate modern analogues in high-strength concrete. Integrating fiber-optic strain sensors within joints, prototypes demonstrate self-centering behavior and maintain vertical alignment after thousands of cyclic load tests—validating the Incas’ millennia-old earthquake-resilient design.[9]

    1 Greek Fire’s Seaworthy Adhesive Mixture

    While renowned as a naval incendiary, Greek Fire also functioned as a hydrocarbon-based sealant that adhered to wet timber hulls. Byzantine texts suggest a blend of pine resin, naphtha, quicklime, sulfur, and pitch. Experimental reenactments at Aristotle University of Thessaloniki using period-accurate pine resin ratios (30–40% wt) and purified bitumen show exothermic polymerization when mixed with lime water, forming a cross-linked matrix that maintains adhesion after a 72-hour saltwater immersion.

    Contemporary chemists analyze these formulations using differential scanning calorimetry to map exotherm peaks and rheometry to assess viscosity changes under shear. Guided by these insights, polymer engineers are developing bio-inspired marine coatings with dual adhesive and hydrophobic properties, achieving pull-off adhesion strengths above 2 MPa and water contact angles exceeding 120°, without relying on toxic antifouling agents.[10]

  • Scientists Found a Neanderthal Population That Lived in Total Isolation for 50,000 Years

    Scientists Found a Neanderthal Population That Lived in Total Isolation for 50,000 Years

    On the bank of the Rhône River in southern France, in a limestone cave known as Grotte Mandrin, scientists have uncovered a puzzle so improbable it took nearly a decade to unravel.

    The jawbone was the first piece. Dug from the cave sediment in 2015, it seemed unremarkable at first glance. But over the next several years, as more teeth and bones emerged, archaeologist Ludovic Slimak and his team began to suspect they had stumbled upon something extraordinary. The remains, eventually dubbed “Thorin” after the Tolkien character, belonged to a Neanderthal unlike any other known.

    What they would come to discover was a new story that suggests Neanderthals were not the single, homogeneous group once imagined, but a patchwork of isolated tribes with vastly different histories.

    “Until now, the story has been that at the time of the extinction there was just one Neanderthal population that was genetically homogeneous,” said Tharsika Vimala, a population geneticist at the University of Copenhagen. “But now we know that there were at least two populations present at that time.”

    A Lineage Out of Time

    Thorin lived sometime between 42,000 and 50,000 years ago, near the end of the Neanderthals’ presence in Europe. From the outset, Slimak had a hunch this Neanderthal was different. The tools found near the remains didn’t match those from surrounding regions. They bore the signature of a cultural tradition known as the Post-Neronian II—unique to this part of France.

    But it wasn’t until researchers sequenced Thorin’s DNA that the full weight of the discovery became clear.

    His genome diverged from those of other late Neanderthals around 105,000 years ago. That’s a staggering timespan. Thorin’s people had been genetically isolated for 50,000 years—even as other Neanderthals and modern humans lived just days’ walk away.

    “The Thorin population spent 50,000 years without exchanging genes with other Neanderthal populations,” said Slimak. “This would be unimaginable for a Sapiens and reveals that Neanderthals must have biologically conceived our world very differently from us Sapiens.”

    This isolation was also social. Unlike other humans, who build vast webs of connection and trade, Thorin’s group seems to have remained apart, both genetically and culturally.

    And they may not have been alone.

    Using comparative DNA modeling, researchers identified at least one other isolated Neanderthal lineage in France around the same time—at Les Cottés—suggesting these small, insular groups were more common than previously believed.

    The Cousin from Gibraltar

    In a surprising twist, Thorin’s closest known genetic relative was unearthed in Gibraltar. DNA from a Neanderthal found at Forbes’ Quarry—on the very southern tip of Europe—shares significant similarity with Thorin’s genome.

    This suggests that Thorin’s ancestors may have migrated North from the Iberian Peninsula, carrying with them both their genes and a distinctive cultural toolkit.

    “This means there was an unknown Mediterranean population of Neanderthals whose population spanned from the most western tip of Europe all the way to the Rhône Valley in France,” said Slimak.

    That genetic connection raises the possibility of a once-broader southwestern European Neanderthal population—one that eventually fractured into isolated communities, as ice age conditions and terrain splintered habitats and movement corridors.

    When Evolution Stalls

    What doomed the Neanderthals has long been a matter of debate: climate shifts, competition with humans, or even catastrophic events. But the discovery of Thorin reframes the extinction question through a more intimate lens.

    “When you are isolated for a long time, you limit the genetic variation that you have,” said Vimala. “That means you have less ability to adapt to changing climates and pathogens, and it also limits you socially because you’re not sharing knowledge or evolving as a population.”

    Thorin’s genome bore the marks of this constraint. Around 7% of it consisted of long runs of homozygosity—stretches of identical DNA that suggest recent inbreeding and very small group size.

    “Thorin the Neanderthal is… an end of lineage. An end of a way to be human.” Slimak told IFLScience.

    A Different Way to Be Human

    The Grotte Mandrin site today stacks layers of human and Neanderthal history like sediment. Thorin’s bones lie nestled between cultural layers—evidence of Neanderthals reoccupying the cave after earlier visits by modern humans.

    Yet there is no trace of interbreeding between Thorin’s group and Homo sapiens.

    That absence speaks volumes.

    “Anthropologically, these gene exchange processes are never limited to a love affair between two individuals,” the authors write in Cell Genomics. “They correspond to the alliances that human populations consciously decide to build.”

    In other words, the social fabric that defines our species—sharing, marrying, mixing—may have been alien to these Neanderthal communities. Where Homo sapiens wove networks, Neanderthals like Thorin walled themselves in.

    Thorin’s remains are still being excavated. Each field season brings more teeth, more bone, more clues. But even as researchers dig, the picture is already shifting. By finding him, we’ve uncovered an entire forgotten lineage—one that reminds us of the human genome’s true variety.

  • New Minor Planet Spotted Past Pluto, One of the Largest Distant Objects in the Solar System

    New Minor Planet Spotted Past Pluto, One of the Largest Distant Objects in the Solar System

    There’s a new frozen oddball orbiting the Sun, and it’s not your average space rock. It’s a planet—a minor one, to be fair—but one of the largest yet discovered and with an orbit around the Sun that puts our own planet’s orbit to shame.

    The minor world is dubbed 2017 OF201; the International Astronomical Union’s Minor Planet Center added the object to its catalog on May 21. Despite its classification, the planet measures somewhere between 290 and 510 miles (470 and 820 kilometers) across. Its upper size limit would put the minor planet in the same wheelhouse as Ceres, the largest asteroid in the belt between Mars and Jupiter, boasting a diameter of about 592 miles (952 km).

    The team of astronomers—led by Sihao Cheng, a researcher at the Institute for Advanced Study—first spotted 2017 OF201 in archival images, but only now is the object officially recognized as a trans-Neptunian object, or TNO. TNOs are bodies in the solar system that orbit the Sun beyond Neptune, which is 30 times more distant from the Sun than the Earth. A preprint describing the discovery is hosted on the preprint server arXiv.

    But 2017 OF201 is superlative even among the distant TNOs; its orbit takes it as far as 838 astronomical units from the Sun—making it nearly 30 times farther than Neptune, which again, is itself 30 times farther from the Sun than Earth is, on average. At its closest, as reported by EarthSky, 2017 OF201 comes within 45 AU of the Sun.

    Dwarf planets.

    That remarkable orbit earns the minor planet the label of an extreme trans-Neptunian object (ETNO), a subset of distant rocks that fuel theories about mysterious gravitational forces at play in the far reaches of the solar system.

    Which brings us, inevitably, to Planet Nine, the theorized distant world posited as a gravitational explanation for the strange clustering of objects in the Kuiper Belt. Other ideas have been floated to explain the phenomenon—such as a ring of debris exerting gravitational influence, or even a primordial black hole—but nothing grips our human fascination like a distant planet, so far away from our solar system’s other worlds that it’s never been observed.

    Planet Nine, if it exists, would have to be a little over six times Earth’s mass, with an orbital period of about 7,400 years. The newly cataloged minor planet is big, but not Planet Nine big.

    Still, discoveries like this keep astronomers buzzing. Just last month, a different team of astronomers found a different slow-moving object beyond Neptune—a would-be Planet Nine candidate, but it’s in the wrong place.

    Objects like those recently reported add to the growing list of bodies that might eventually help pinpoint the elusive Planet Nine—or at least explain the strange movement of objects on the periphery of our solar neighborhood.

    2017 OF201 isn’t the planetary heavyweight many have been waiting for, but it’s a reminder that the solar system is still full of surprises—especially in its frigid, hard-to-see suburbs.

  • 10 Interesting and Bizarre Facts About Vending Machines

    10 Interesting and Bizarre Facts About Vending Machines

    Vending machines are everywhere—from high schools to hospitals to subway platforms—but they’re more than just mechanical snack dispensers. Behind those blinking lights and humming motors lies a strange and fascinating world of quirky innovations, cultural oddities, and unexpected trivia. These automatic vendors have dispensed everything from holy water to hamburgers, and their evolution is filled with stories that are, at times, brilliant, baffling, and downright bizarre.

    So grab your change—or, more likely, your contactless card—and take a look at ten facts about vending machines that are anything but ordinary.

    10 A Mystery Vending Machine Went Missing in 2018

    For decades, a mysterious vending machine stood on Seattle’s Capitol Hill, quietly offering a selection of rare, vintage sodas for just 75 cents. The machine was unmarked and weathered, with cryptic buttons labeled things like “Mystery” or “?.” When pressed, they would dispense obscure drinks long thought discontinued, such as Crystal Pepsi and Black Cherry Fresca.

    Who stocked this retro machine that only took coins? No one knew, and when it disappeared in 2018, leaving behind a note that read “went for a walk,” nothing was made clearer. Some believe it was an elaborate art project or guerrilla marketing stunt, but we may never know the truth.[1]

    9 They Can Be a Loophole for Gambling

    There are many places in the world where you can enjoy a game of Blackjack or sit for hours at a slot machine, and there are also countries where it’s illegal.

    But that doesn’t mean it can’t be done. In countries like Thailand, the United Arab Emirates, and especially Japan, vending machines offer an interesting loophole. Often called “lucky boxes” or “mystery boxes,” these machines dispense boxes with prizes that vary in price. The option to win a box of tissues or an iPad satisfies the gambling itch without actually being considered such.

    More and more countries are catching wind of these mystery machines. They are banning them, especially because they offer a gateway for children and teens to become addicted to gambling.[2]

    8 Surge Pricing Machines Were Tested by Coca-Cola

    Coca-Cola has had a lot of failures in its long history. From Coca-Cola Energy to the infamous New Coke, the multi-million dollar company has had some embarrassing moments. One of the lesser-known escapades was tested in 1999 when new vending machines with variable pricing were introduced.

    These new vending machines would automatically detect the outside temperature and adjust the price accordingly—hot weather means higher prices, naturally. Like how Uber and Lyft charge more when it’s raining, Coca-Cola knew that people want an ice-cold drink on a warm day. But unlike rideshare programs, these vending machines were physical objects that could—and would—have some anger taken out on them.

    When thirsty buyers were met with a more expensive drink, so many of them either didn’t buy a Coke or took their frustration out on the machine itself that it was deemed not financially worth it to Coca-Cola to expand the idea.[3]

    7 Even Animals Can Use Them

    Monkeys are notorious for their uncanny intelligence and sneakiness, especially when it comes to food. Videos of monkeys taking bananas, chips, and even cell phones from unsuspecting tourists all over the world have gone viral since the dawn of the internet.

    So perhaps it should come as no surprise that Japan has seen monkeys that have figured out how to use vending machines. Multiple stories and videos feature monkeys either stealing or being given money and then inserting it into the machines, selecting their snack, and receiving it.

    Sure, it’s impressive, but monkeys are famously smart animals. What would you say if I told you crows have proven to be able to do the same thing? In 2018, a small island in the South Pacific created a vending machine specifically for these birds. The crows were shown that food comes out if they insert a piece of paper into a slot. Not only did they instantly understand, but they were able to rip the paper to the correct size to ensure it would fit in the slot.[4]

    6 They Used to Sell Cigarettes

    Though they’re now banned in most countries, there was a time when you could purchase cigarettes and other tobacco products just by using a machine. Even as far back as 1615, one could buy snuff and tobacco in English taverns via a coin-operated machine, but it wasn’t until 1926 that cigarette machines really took off.

    Suddenly, diners, cafes, and bars across the world had an easy way to appease customers without bothering workers. Unfortunately, as the harmful effects of cigarettes came into public light, age restrictions also rose in popularity. It became impossible for machines to operate, as there was no way to verify the ID or age of buyers. The few countries that allow them now generally require one to show an ID to a worker and then are given a token to insert into the machine to enable the purchase. Other countries, like the United States, only allow cigarette machines in places where people under 18 are not allowed, such as clubs and bars.[5]

    5 They Were Used in Victorian Times

    Though the concept of vending machines has been around for thousands of years, the first modern version of what we know today cropped up in 1883 when Percival Everett designed a vending machine dispensing postcards. It was an instant hit at railway stations and post offices and soon began to carry envelopes and note paper.

    Just four years later, candy and chocolate companies realized the profit of having these snack dispensers on every corner, and 15,000 were installed in Germany alone. In 1888, the United States got its first vending machine in the form of a gum allocator, and it was a hit on train platforms in New York City. Though the popularity of vending machines didn’t explode until the introduction of automatic restaurants, the fact stands they existed even in Victorian times.[6]

    4 At One Point, 1 in 9 Coca-Cola Purchases Was a Dud

    In the 1950s, Coca-Cola had a problem. They were known for the cheap price of their iconic soda, which had been just five cents for over thirty years.

    Unfortunately, inflation was taking its toll, and the vending machines weren’t able to reliably make change, so customers needed to have exact change in order to make a purchase. However, the company worried consumers wouldn’t want to carry multiple coins if they raised the price by just one cent.

    Coca-Cola approached the U.S. Treasury Department in 1953 and asked them to mint a 7.5-cent coin. When this didn’t work, they took a creative step by implementing a new program in which one out of every nine Coke bottles was empty. These “blanks” meant a few patrons would have to pay ten cents for just one bottle, raising the price to 5.625 cents.[7]

    3 They Can Withstand Natural Disasters

    Japan is widely considered to be the vending machine capital of the world. From classic sodas and chips to more risqué items, these are more than a convenience throughout the country—they’re a way of life.

    And now they can actually help save lives. While some vending machines in Japan are beginning to be built to withstand earthquakes, which are common in the area, a few take it even further. The Japan Times reports that some machines are now equipped with external defibrillators and flood detectors. When a natural disaster is detected, these high-tech vending machines dispense food and beverages (and even Wi-Fi) for free.[8]

    2 They’re Deadlier Than Sharks

    The release of Jaws in 1975 struck fear of sharks into the hearts of millions. Suddenly, every trip to the beach was tinged with horror—the idea of a bloodthirsty great white chomping on an arm or leg led to an uptick in galeophobia (fear of sharks). But if you’re a practical person, you’d do better to have a healthy fear of vending machines because they actually kill more people per year than sharks.

    Every year, an average of just three or four people in the world die due to shark bites. Compare that with the number of people who are killed by vending machines—thirteen. Though they can’t menacingly stalk you through murky waters, vending machines have been known to fall and crush customers—usually people who are trying to force an item out.[9]

    1 The First One Dispensed Holy Water

    Today, you can purchase almost anything from vending machines. Cupcakes, pizzas, crabs, socks, books, caviar, and even used underwear can be bought simply by tapping a card or inserting a few bills.

    However, in the 1st century AD, Hero of Alexandria developed the novel idea of inventing the first of these evolved machines. Though it seems impossible for such a high-tech contraption to have been started two thousand years ago, it’s fairly simple. As the Smithsonian explains: “Put a coin in a slot at the top of a box. The coin hits a metal lever. On the other end of the beam is a string tied to a plug that stops a container of liquid. As the beam tilts from the weight of the coin, the string lifts the plug and dispenses the desired drink until the coin drops off the beam.”

    Notice that it dispensed liquid—though not the kind you’re probably thinking of. Instead of Pepsi or Coke, Hero’s machine only allowed the buyer to purchase water. Not for drinking, though—for blessing oneself. Placed outside churches, the vending machines only released holy water. They were created to respond to people taking more holy water than they were paying for.[10]

  • A Swedish Library Forgot to Close Its Doors and Something Beautiful Happened

    A Swedish Library Forgot to Close Its Doors and Something Beautiful Happened

    When Anna Carin Elf arrived at her workplace in Gothenburg, she immediately realized something was not right. She works at a library, and she was greeted by several visitors, just like any other day. But this was not any other day — the library was supposed to be closed for All Saints Day — a celebration sometimes also called All Hallows Day, the precursor of Halloween.

    The visitors were also surprised, Elf says. “They thought it was a bit empty. But the people in the library behaved as usual. Many were sitting reading newspapers, some families were in the children’s section and others were searching for books on the computer.”

    Unbeknownst to the staff, a door had been left unlocked the previous evening. Throughout the day, 446 visitors entered the library, unaware it was officially closed. Families gathered in the children’s section, individuals browsed the shelves, and others perused newspapers—all behaving as they would on any regular day. Some patrons even borrowed books using the self-service system. By day’s end, 246 books had been checked out, and remarkably, every single one was returned on time.

    Some visitors realized the library was technically closed and went home, but others did not.

    As people were coming in and out of the library, one librarian (Elf) walked by and noticed the people using the library. She realized what was happening, called her manager and a colleague, and then announced that the library was closing. The visitors calmly folded their books closed and left.

    The reading room at the Gothenburg School of Economics.

    This unplanned event is a testament to the community’s respect for shared spaces and resources. In an era where trust in public institutions often wavers, the citizens of Gothenburg demonstrated that integrity and responsibility remain deeply rooted values. The library staff, upon discovering the oversight, expressed gratitude for the patrons’ conduct, noting that nothing was damaged or stolen. Elf remarked on the situation, highlighting the community’s unwavering respect for the library.

    The City Library published a loving post, thanking people for their well-behaved visits. “Thank you for Saturday, dear Gothenburg,” the library’s post read.

    “It felt good that everyone behaved exactly as usual, they borrowed books, read the newspaper and so on… the citizens of Gothenburg take care of their library. There is obviously a desire to be there,” said one of the library’s visitors, Arvid Jadenius, for a local publisher.

    The incident also sparked discussions about the evolving role of libraries in society. With advancements in technology and the increasing availability of digital resources, some question the necessity of physical library spaces. However, this episode underscores the library’s role not just as a repository of books but as a communal haven—a place where trust, learning, and community converge.

    In the days following, the library shared a heartfelt message on social media, thanking the citizens for their respectful use of the space during its unintended opening.

  • TikTok Is Going to Make These Two Cameras Nearly Impossible to Buy

    TikTok Is Going to Make These Two Cameras Nearly Impossible to Buy

    The one thing I have in common with the average TikToker is my longing for expensive fixed-lens point-and-shoot cameras. It seems the two companies—Fujifilm and Ricoh—have the biggest brand recognition by the app-obsessed crowd, and they’re individually calling up two cameras to help feed audiences and algorithms alike. The first on our list from the folk at Fuji looks and feels incredibly old school, but it’s designed specifically to funnel vertically-oriented shots to an Instagram account.

    We won’t have to wait long for the most anticipated cameras of the year. First up, Fujifilm finally announced its $850 X Half camera. If you’re wondering about the strange naming convention, it’s because the fixed-lens camera is a “half-frame” shooter with a portrait-oriented, 18-megapixel sensor. The lens is equivalent to 32mm with an f/2.8 aperture. It includes a far more shrimpy body and half the sensor size compared to the company’s landmark X100V and X100VI point-and-shooters. It sports an old-school, lightweight body complete with an actual working tactile frame advance lever. The rear screen is dedicated to seeing your shots in the 3:2 aspect ratio and for picking from 13 different film simulations that have become such a staple on Fuji’s digital products.

    If you didn’t already think this camera was made for the person who simply wants to funnel their photos to Instagram, then know the Fujifilm X Half won’t shoot in RAW format, which is what the vast majority of professionals prefer for photo editing. Instead, it features a dedicated smartphone app. It will also operate with various Instax printers. Fujifilm said this camera is directed at the Gen Z audience who want a digital camera to use alongside their phone.

    You need to use the frame advance lever after taking every image, which makes the X Half seem more of an expensive film camera simulation than a professional device. And yet, there’s something magical about the limitation inherent with film cameras that’s missing from today’s high-end digital devices. The camera even includes grain effect and time stamp options to add noise to your final shots. The Fujifilm X Half should be available in late June.

    Ricoh Gr Iii Front On 1024x1024

    If you were looking for something that’s a little more typical, Ricoh is edging closer to finally unveiling the sequel to its all-time classic fixed-lens camera, the Ricoh GR III. In a release, Ricoh said the Ricoh GR IV is in development. It will sport a redesigned lens, a new sensor, and a redesigned digital imaging engine. The company suggested the new shooter may also connect to a new app, which should make it easier to get from the camera directly to your phone. We won’t actually get to see what it looks like until May 31, when it will be shown off at various GR Spaces in Tokyo, Beijing, and Shanghai. We’ll have to wait until the fall for a full release.

    TikTok’s attention has largely spun away from its previous darling, the Fujifilm X100VI. That’s despite the initial glowing reviews of the more expensive $1,600 camera. The X100VI has been notoriously hard to acquire new or used. Meanwhile, the Ricoh GR III (which you can still find for under $1,000 used or about $1,100 new) has been around for more than five years, and it’s still one of the gold standards of this compact form factor thanks to its low-key design and its capacity to take crisp shots. There are two versions of that camera with the same 24.2-megapixel APS-C sensor—the GR III with the 28mm lens and the GR IIIX with a 40mm lens that’s better for close-ups and street photography.

    It may be harder for today’s internet-famous photographers to get one of these cameras going forward. Ricoh said it will stop shipments of the GR III in July “due to difficulty in procuring parts and components,” but the GR IIIX should be available for a while longer. The wait until then may be excruciating for those of us desperate for another unassuming but ultimately powerful camera.
