31 Namibia’s Barren Fairy Rings

Scattered across the arid landscape of Namibia, mysterious barren patches known as Fairy Circles have puzzled scientists and locals alike for decades. These nearly perfect circles, ranging from 1 to 15 meters wide, are completely devoid of vegetation and are often surrounded by taller grass on their edges. While similar formations were also reported in Australia’s Pilbara region, Namibia remains the global hotspot for these strange formations, which the local Himba people have long accepted as part of nature-sometimes even using them as makeshift cattle pens.
Several theories have been proposed to explain the phenomenon. One long-standing idea attributes the circles to sand termites that clear vegetation above their underground colonies. However, this theory has lost favor due to inconsistent evidence of termite presence across the circles. A more compelling theory suggests that intense plant competition in Namibia’s harsh environment leads grasses to create natural nutrient reserves by killing off interior vegetation and hoarding resources at the circle’s edges. Some locals believe the circles have supernatural origins, calling them “footprints of the gods,” while fringe theories even suggest alien communication.
32 Mystery of Haplogroup X

Haplogroup X is a rare and puzzling type of mitochondrial DNA found in small percentages among people in Europe, the Near East, North Africa, and notably, among some Indigenous groups in North America. While other Native American DNA haplogroups can be traced to Asia and the Bering land bridge migration, Haplogroup X-specifically its X2a variant-doesn’t follow this pattern and is strangely absent in East Asia. This has led to confusion among scientists about how it ended up in North America at all, especially since it shows up in high percentages among tribes like the Algonquian, Sioux, and Navajo. The highest known concentrations in the world are among the Druze people of the Near East, who also show exceptional diversity in this haplogroup, suggesting ancient and isolated origins.
Various theories have tried to explain this genetic mystery. One early theory, the Solutrean hypothesis, claimed that Haplogroup X arrived in North America via Stone Age Europeans crossing the Atlantic by boat, but newer studies show no link between the American X2a and any European DNA. Instead, it appears that X2a developed independently in early Native American populations over 13,000 years ago. Other fringe ideas-from ancient Israelites to Atlanteans to aliens-have been floated but lack any scientific backing.
33 Tarrare: France’s Hungriest Enigma

Tarrare, a mysterious figure from 18th-century France, remains one of medical history’s strangest unsolved cases. Born to peasant parents near Lyon, he displayed a monstrous appetite from a young age, reportedly eating his own body weight in meat daily without gaining weight. Despite his emaciated appearance, he could stretch his stomach skin dramatically and emitted an unbearable odor that made proximity difficult. Abandoned by his family, he joined a traveling freak show, performing grotesque acts like swallowing stones, live animals, and crates of food, becoming a street-side spectacle of human consumption. His unique condition caught the attention of military doctors during the French Revolutionary Wars, and he was even used as a human courier to smuggle secret messages into enemy territory-though this mission ended in capture and near execution after he was found out in Prussia.
Desperate for help, Tarrare sought cures from Dr. Percy, but nothing could quell his hunger. Hospitalized again, he was caught drinking blood and lurking near the morgue, suspected even of eating a missing child, which led to his final disappearance. Years later, he reappeared in Versailles, dying of a mysterious gastrointestinal illness marked by extreme internal decay. His autopsy revealed severely decomposed organs, but offered no concrete answers. To this day, experts can only speculate whether his affliction stemmed from a rare metabolic disorder, thyroid dysfunction, or an entirely unique syndrome.
34 Copper Scroll Treasure

The Copper Scroll, discovered in 1952 at Qumran’s Cave 3, is unique among the Dead Sea Scrolls because it was inscribed on metal rather than parchment. It couldn’t be unrolled normally, so it was cut into 23 strips in the 1950s. Scholars date it between 25 and 135 CE, and it is written in an unusual form of Hebrew not typically seen in biblical texts. The scroll lists 64 locations supposedly hiding vast treasures of gold, silver, and sacred vessels, some possibly linked to the Jewish Temple in Jerusalem. Though detailed and specific, the directions assume a deep familiarity with obscure places, and no duplicate document mentioned in the scroll has been found.
Debate surrounds the authenticity and origin of the treasure: some believe it was real Temple wealth hidden during times of conflict, while others think the scroll could be a work of fiction. Certain features-such as similarities to Greek temple inventories and writing techniques consistent with hammering into metal-suggest it could be a legitimate administrative record. However, it is also possible the Romans seized the treasure when Herod’s Temple was destroyed. Today, the Copper Scroll is housed in the Jordan Museum in Amman, and the treasure, if it ever existed, remains undiscovered.
35 Origins of Phosphine on Venus

In 2020, the unexpected detection of phosphine-a potential biosignature-high in Venus’s atmosphere stunned the scientific community, since the harsh environment of the planet seemed utterly incompatible with life as we know it. Phosphine is produced by microbes on Earth and breaks down quickly in oxidizing atmospheres, yet astronomer Jane Greaves’s team found it at puzzlingly high concentrations in the temperate cloud layer 50 kilometers above Venus’s hellish surface. The findings, initially detected using powerful radio telescopes, were disputed by other astronomers who argued the signal was likely sulfur dioxide contamination, but further analysis and a 2024 redetection supported the original claim.
Attempts to explain the phosphine through non-biological means-ranging from lightning and volcanic activity to meteoritic delivery-have largely fallen short, with models failing to reproduce the observed concentrations under any plausible Venusian conditions. Critics argue that incomplete knowledge of Venus’s geology leaves room for alternate interpretations, particularly ongoing volcanic activity. While some suggest microbial life in the clouds as a possible source, others propose that the gas may be pointing to previously unknown geologic or photochemical processes.
36 Sleeping Village of Kazakhstan

Between 2013 and 2016, a baffling phenomenon struck the remote village of Kalachi in northern Kazakhstan, where dozens of residents began falling into sudden, prolonged sleep-sometimes while walking, driving, or even mid-conversation. The symptoms mimicked drunkenness at first-slurred speech, dizziness, and loss of balance-before victims succumbed to sleep that could last for days, with no memory upon waking. Investigations revealed no contamination, radiation, or consistent medical cause, and while isolated cases dated back to 2011, the full-scale waves of the “sleeping sickness” led to partial evacuations before the condition mysteriously disappeared in 2016 as suddenly as it had emerged.
Several theories have attempted to explain the outbreak. The official government stance blamed carbon monoxide from nearby abandoned Soviet uranium mines, though this failed to align with the absence of carbon monoxide in medical tests. Another theory proposed chemical leakage into the village’s water supply, but no evidence of water contamination or toxic waste was found. The most psychological explanation suggests mass psychogenic illness (mass hysteria), triggered by shared anxiety and stress, though that too lacks definitive proof. To this day, no single explanation can fully account for the strange wave of sleep that swept through Kalachi.
37 Joshua Maddux: Boy in the Chimney

In 2008, 18-year-old Joshua Maddux vanished after leaving home for a walk in the town of Woodland Park in Colorado. His disappearance prompted a prolonged but fruitless search that led many, including his family, to believe he had simply left town to start anew. Seven years later, his mummified body was discovered in the chimney of a nearby abandoned cabin—less than a mile from his home—wedged in a fetal position with no signs of trauma, injuries, or drug use, yet surrounded by baffling clues: his clothes were neatly folded inside the cabin, and he was found wearing only a thin thermal shirt.
Authorities ruled the death accidental, suggesting Joshua climbed down the chimney and became trapped, ultimately dying of hypothermia—but this theory was challenged by the property owner, who stated the chimney had been sealed with wire mesh for years. Further disturbing details emerged: the position of the body would have required him to enter headfirst and possibly with assistance, and a Reddit post linked a local man named Andy—later institutionalized—to suspicious comments implying involvement. Joshua’s tragic fate remains steeped in unsettling contradictions and unanswered questions, hinting at a mystery far darker than a simple accident.

15 Most Controversial & Costly Blunders in History
38 Rasputin and Hemophilia

Grigori Rasputin, a controversial figure in Russian history, was often portrayed as a mystical healer and spiritual advisor, though many believe he was more of a manipulative and charismatic opportunist who skillfully embedded himself within the Romanov court. His rise to prominence came largely through his inexplicable ability to alleviate the suffering of Tsarevich Alexei, the young heir to the Russian throne, who was born with hemophilia-a life-threatening blood disorder that caused severe and spontaneous internal bleeding.
Traditional medicine at the time had little to offer, and the royal family grew increasingly desperate with each of Alexei’s medical crises. Rasputin, however, appeared to succeed where doctors could not: when he was near the boy, Alexei’s condition would improve, and even when Rasputin was far away, his letters and telegrams-often filled with calm, reassuring words-were said to have a soothing, almost miraculous effect on the child’s health. His ability to bring relief, whether through psychological comfort, hypnosis, or sheer coincidence, earned him unwavering loyalty from Empress Alexandra and made him an indispensable presence at court, despite widespread suspicion and political backlash. Rasputin’s strange healing connection to the tsarevich remains one of history’s most puzzling medical and psychological mysteries.
39 Curious Case of Evan Muncie

When a devastating 7.0 magnitude earthquake struck Haiti in January 2010, millions were affected and hundreds of thousands perished, but amidst the rubble emerged the astonishing story of Evan Muncie-a 28-year-old rice vendor who was found alive 27 days after the quake. Despite extreme dehydration, malnutrition, and minor wounds, Evan survived in what many called a miracle, baffling medical experts who stated that no human could survive that long without water, especially in such conditions.
What made his case even more mysterious was Evan’s account of being visited by someone in a white coat who gave him water, though no physical evidence supported such a possibility given the space he was trapped in. While some have speculated that delirium led to hallucinations or that Evan was only trapped for a shorter time, his emaciated condition and the fact that he was reported missing on the day of the quake raise more questions than answers. Whether through divine intervention, a rare survival anomaly, or something else entirely, the truth behind Evan Muncie’s survival remains an enigma.
40 Marine Phosphorescent Wheels

For over a century, sailors have reported encountering eerie and spectacular displays of “marine phosphorescent wheels”—massive, glowing circular patterns of light that appear on or beneath the surface of the ocean, particularly in the Indian Ocean, Persian Gulf, and South China Sea. These rotating wheels, sometimes accompanied by luminous spokes or parallel bands of light, can stretch for hundreds of meters, appear to spin at high speeds, and often occur in complete silence, baffling observers.
Despite a wide range of proposed explanations—from glowing plankton reacting to physical disturbances, to seismic activity, or even connections to UFO phenomena—no definitive cause has been confirmed, and accounts vary wildly in appearance and behavior. Witness reports describe surreal scenes, such as seas glowing like snowfields or being surrounded by spinning blue cartwheels of light, all pointing to one of the ocean’s most dazzling and least understood mysteries.
RE: Fact #35 (Origins of Phosphine on Venus) – Man, I was stoked when I first heard about this! I was really looking forward to learning more about Venus. Turns out, though, the findings aren’t exactly what everyone else in science is buying.
RE: Fact #14 (Green Children of Woolpit) – I really dig this idea from ancient origins: Paul Harris, in Fortean Studies, thought the kids were Flemish orphans, maybe from Fornham St. Martin near Woolpit, separated by the River Lark. Lots of Flemish people moved there in the 12th century, but King Henry II was rough on them, even killing many near Bury St Edmunds in 1173. If they ran off into Thetford Forest, it would’ve been super dark and scary for kids. They might’ve even gone through those old mine tunnels to Woolpit. Imagine – weird clothes, speaking a different language… they must’ve freaked out the villagers!
RE: Fact #43 (Viking Maine Penny Baffles Historians) – It probably got there through trading.
It’s easy to imagine Vikings making several trips to America. The stories only mention a few, but there could have been more. Crossing the ocean was dangerous, so not all of them might have returned to tell the tale.
There’s a cool book about Gudrid, a Viking woman who traveled the world long ago. It’s called *The Far Traveler: Voyages of a Viking Woman*, by Nancy Marie Brown.
RE: Fact #7 (Rohonc Codex: Fake Manuscript or Real?) – I always wondered if it was someone with mental health issues. Honestly, I love the illustrations! They’re a little rough around the edges, but they’re gorgeous and intriguing. They don’t look like the work of a professional manuscript illustrator—they’re unlike anything I’ve ever seen.
RE: Fact #33 (Tarrare: France’s Hungriest Enigma) – His last illness might’ve been partly caused by tuberculosis, but the term “consumption” back then was pretty vague. They used it for all sorts of wasting diseases, not just TB. Plus, his symptoms – mostly a messed-up gut full of pus – don’t exactly shout “TB!”
Abdominal TB is real, and what the doctors saw fits with that, especially if it went untreated.
TB can affect the abdomen in a few ways. It can get into the gut from infected milk or spit, causing sores and spreading to lymph nodes and the lining of the abdomen. Sometimes, it even reaches the liver, pancreas, or spleen.
His body probably rotted faster because his gut was already wrecked and bacteria were running wild.
I bet some of the weird stuff in this case is just because medicine was so basic in the early 1800s.
RE: Fact #28 (Crutches Everywhere: Sweden’s Hip Mystery) – I really hate it when doctors just call something psychosomatic when they don’t know what’s going on. It’s like, “I’m stumped, so you’re making it up!” Seriously, figure it out!
RE: Fact #47 (Aksum’s Mysterious Fall from Power) – Hey, nobody has commented about this yet! My husband’s Egyptian, and we both thought it was super interesting. Thanks!
RE: Fact #49 (The Jumping Gene Mystery) – Wow, that’s wild! It’s all about those genes just chilling and spreading around, I get it.
RE: Fact #1 (Did the Inca Sail to Distant Lands?) – This is a really cool story, but I have a couple of quick questions. First, I don’t think Aboriginal Australians were mining or working with gold and brass. And horses weren’t around in Australia back then. Second, Polynesians could be darker-skinned than Incas, it’s not a big deal, but maybe the voyage went to a different part of South America where darker people had those things. They seem more common in mainland South America than the Pacific.
RE: Fact #39 (Curious Case of Evan Muncie ) – That’s one heck of a story! I’m really happy that guy got out of there.
But I don’t buy the supernatural stuff at all.
There’s this thing called the Third Man Factor—it pops up a lot in survival stories. Basically, people feel like they have a helpful presence with them during the ordeal, giving them support. Exactly *why* that happens is up for grabs; some just feel calm and sure they’ll make it, while others see actual hallucinations.
As for how Evan Muncie survived being trapped under all that rubble… well, he wasn’t moving around or eating, and he was shaded from the sun, so he probably needed way less water. He might have gotten some rainwater or groundwater, too. And some people can just survive longer without water than you’d expect. It’s not fully understood, but maybe he was just incredibly lucky—his body and the situation just happened to line up perfectly.
RE: Fact #26 (Where Do Eels Come From?) – There is probably an obvious answer that I’m missing for this, but if their larvae and eggs haven’t actually been seen, how do we know that they aren’t laying them before they go off on their migration? This is a great entry. ! Love ecological mysteries.
RE: Fact #26 (Where Do Eels Come From?) – That’s awesome, thanks! I’m teaching environmental science and used the eastern Canadian elver overfishing problem for my final exam. I was totally blown away by how those tiny things navigate the ocean.
RE: Fact #4 (Africa’s Forgotten Atlantic Expedition?) – Most historians agree this didn’t happen. There’s no real proof, and it’s not a major historical idea.
RE: Fact #20 (Surviving Everest’s Death Zone Night) – Besides the decent weather, Hall could walk, which was huge for surviving. No walking, no chance past a certain point – no rescue.
Great article! I love reading about high-altitude mountaineering, from the comfy couch, of course. That mountaineer, Joe Simpson, wrote some fascinating books about the ethics of rescuing people up high. He’s experienced both sides – falling into a crevasse, being left for dead, then crawling miles with awful injuries to get himself out.
RE: Fact #50 (The Lonely 52 Hz Whale ) – Whales are awesome, I wrote papers on them in college. Their communication is way more complex than you’d expect – check out bowhead whale songs, they’re amazing! I really hope this whale gets to live in peace.
I find the idea that it’s deaf really interesting. It seems unlikely to be a completely unique species, since it’s the only one doing this. It’s hard to believe it’s the last one of its kind, especially one that hasn’t encountered humans before. Whales live for ages, so you’d think we’d have found another if there was a whole separate species. Maybe its unusual swimming is because it can’t find other whales. Its migratory instinct is probably in its DNA, but without being able to communicate, it’s probably just going it alone.
RE: Fact #7 (Rohonc Codex: Fake Manuscript or Real?) – This might sound silly, but seriously—if people have made up whole languages just for fun, why couldn’t something like this, or the Voynich manuscript, be a language made up by a small group? Maybe even just one monk in a monastery, just for kicks.
RE: Fact #36 (Sleeping Village of Kazakhstan) – Carbon monoxide poisoning is probably the reason.
I read a story on facebook about Syrian refugee kids who slept all the time. It was written like a mystery, but it seemed like the massive stress of war and growing up as a refugee was the real cause. If it’s not carbon monoxide, I wonder if there was something else really stressing those villagers out.
RE: Fact #10 (The Yuba County Five) – This case has always fascinated me—it’s basically the American Diatlov Pass. Stuff You Should Know did a great podcast about it, and there’s also a YouTube video if you prefer watching.
RE: Fact #41 (Fate of the Amber Room) – Wow, that’s a great piece, but it’s depressing to think about all the art, history, and culture lost in wars.
RE: Fact #29 (Mysterious Upsweep Sound) – The trouble with thinking up a sea monster big enough to make that much noise is that the deep ocean just doesn’t have enough food for something so huge. People always bring up Megalodon, saying there’s plenty of unexplored ocean where a bunch of bus-sized sharks could hide. But even with weird finds like the megamouth shark, an animal that size – whether it hunts or filters food – needs tons of food.
So picture this giant Upsweep noisemaker. It’d have to be massive to make a sound that loud, heard all across the Pacific. And it lives deep down, around 2500-5000 meters – Cuvier’s beaked whales dive almost that deep, so it’s possible. But unlike whales, this thing rarely comes to the surface. Nobody’s ever seen anything that big. Plus, food’s scarce down there, so it’d probably be a slow-moving filter-feeder, which makes it hard to figure out what kind of animal it is. It’d be more like a giant clam than anything else, and clams don’t make much noise, which is a problem.
So, I’m guessing it’s some kind of geological thing. But I have to say, a house-sized geoduck making those sounds as it shuffles along the ocean floor is pretty cool.
RE: Fact #3 (Mystery of Vietnam’s Rock Apes) – My uncle served in Vietnam and used to tell us crazy stories about these Rock Apes. Even years later, the guy was still scared stiff of them! He’d chat about the Viet Cong no problem, but Rock Apes? Only after a few beers, and even then, he’d be totally freaked out.
I only knew a couple other guys who were there, and only one of them never mentioned anything about those things.
RE: Fact #38 (Rasputin and Hemophilia) – Back then, aspirin was the big new thing. It messes with blood clotting, which is really bad for hemophilia. When Nicholas and Alexandra let Rasputin take over, he stopped giving the kid aspirin. That probably played a big part in what happened, along with everything else.
I don’t think Rasputin even knew aspirin was dangerous for hemophilia. He probably just stopped the medicine because he thought his “healing” would work. Seems like Rasputin got really lucky.
RE: Fact #8 (Washington’s Sea Eagle: America’s Lost Giant?) – This mystery’s always been a favorite of mine. I recall reading a theory suggesting both eagles were first-year birds with chicks, but that doesn’t account for their size or other reported sightings. It’s a real head-scratcher!
RE: Fact #10 (The Yuba County Five) – From what I’ve read and heard, they all had developmental disabilities that made independent living tough. It sounds harsh to say, but their problem-solving skills weren’t as strong as the average person’s. I don’t know the specifics of their disabilities, but if living alone was a struggle, then something like getting their car stuck would’ve been really hard. Even for someone without disabilities, that’s a panic-inducing situation!
So, yeah, they could’ve easily gotten the car unstuck and waited for help, but their disabilities might’ve made that impossible. Add in the stress and fear of being lost, and leaving the car on foot doesn’t seem so crazy.
RE: Fact #50 (The Lonely 52 Hz Whale ) – I’m thrilled that whale might have found a partner!
RE: Fact #11 (Mysterious Soda Machine of Capitol Hill) – That title made me think it was about Congress getting snacks from a vending machine! Lol
RE: Fact #42 (The Mask That Wasn’t Agamemnon’s) – Schliemann kicked the bucket in 1890 and got a huge burial, like a Greek temple.
Could that mask have belonged to some rich but totally unimportant Mycenaean bigwig?
That whole thing’s kinda funny. I bet tons of “historical” discoveries are wrong, just some rich person’s quirky idea. People are still the same, right? Maybe someone really wanted to be like a legendary figure from the past.
RE: Fact #6 (Whispers from the Headless Valley) – I googled it on maps—cool to see some truly remote spots still exist!
RE: Fact #8 (Washington’s Sea Eagle: America’s Lost Giant?) – I wonder what would happen if we could DNA test one of those stuffed birds and compare it to bald and golden eagles – if there’s any DNA left, that is.
From what I’ve read, it’s hard to believe Audubon, with his background, would have mistaken another bird for this one.
Plus, this mystery bird seems to behave so differently from other eagles that it’s probably a whole new species.
RE: Fact #3 (Mystery of Vietnam’s Rock Apes) – It’s great to see a cryptozoology case posted on factrepublic! This cryptid’s been around for ages, not just during the American war. The Vietnamese call it Người Rừng. I totally buy that it could be real, especially with all the new megafauna discoveries in Vietnam lately.
RE: Fact #12 (The Dalby Spook) – This cryptozoology case really freaked me out as a kid! I was terrified a Gef was living in our attic stairs. Thanks for bringing those memories up.
