Fact: Fetuses can turn to stone—and stay inside their mothers for decades



By Rachel Feltman



A few years ago, a 75-year-old Moroccan woman named Zahra Aboutalib went to the hospital with abdominal pain. Scans revealed a strange mass, and eventually, doctors figured out the shocking source of her pain: a baby she conceived 46 years before. You can learn more about Aboutalib's incredible ordeal in this documentary about her, but as shocking as her condition was, she isn't alone: There are some 300 cases of lithopedions, or stone babies, in the historical record. They're actually described in medical literature as early as the 10th century.



A stone fetus sounds kind of terrifying, but the phenomenon is actually rather amazing. This generally occurs when an abdominal ectopic pregnancy—a fetus growing inside the abdominal cavity instead of within the uterus—is not reabsorbed by the hosting body, but instead treated as a foreign invader and covered with a calciferous substance. The result is a fetus covered in a protective layer quite literally as hard as rock. Patients like Aboutalib can go for years or decades ignoring the resulting mass, and some of them have even had healthy children while continuing to carry the lithopedion.


Fact: Listen up, Marvel—this newt is basically Wolverine



By Mary Beth Griggs



Meet the Iberian Ribbed Newt. Sure, it looks cute, but behind that adorable amphibian face is a consummate survivor. And if you try to threaten its life, this relative of the salamander will go to great lengths to take you down with it.



When threatened, it turns its own body into a weapon, shoving its ribcage forward along its spine so that the sharp ends of its ribs poke out through the skin. As if bristling with bony needles wasn't enough, it also starts secreting a poison that coats its skin and the ends of those points, delivering a deadly dose to smaller critters.



But that's not the coolest thing. When it finds a moment of peace, the newt relaxes its ribcage back into the normal position—and the wounds heal themselves right back up, making this amphibian a real-life Wolverine.



FACT: This guy (maybe? probably?) died by autopsy



By Eleanor Cummins



Washington Irving Bishop lived fast and died young. Born into an occult-loving family in 1855, he became a famous “thought-reader,” traveling around under the stage name “The Mentalist.” His performances were only heightened by his penchant for passing out—often on stage, in the middle of a performance. In these strange trances—called “cataleptic fits”—he would become immobile, and stop responding to any stimuli. Naturally, he carried around a card in his pocket that said something to the effect of, “I may look dead, but I swear I’m not, so please don’t autopsy me.”



Unfortunately, his warnings were not heeded. During an infamous performance in 1889, he slipped twice into such a trance. And he failed to emerge from the second—at least not in a timely enough fashion for the doctors of the day, who autopsied him the next morning.



Today, Bishop’s body is interred among other prominent 19th-century characters at Green-Wood Cemetery in Brooklyn. His tombstone, while degraded by rain and sun, is notably emblazoned with the words “THE MARTYR” and an accompanying statement from his mother, who believed for the rest of her life her son had been killed by his autopsy.



FACT: Some people hear illusive explosive sounds before falling asleep.



By Claire Maldarelli



I have always been fascinated by the phenomenon of unidentified sounds. That includes ones like the Taos Hum, where a percentage of residents in the town of Taos, New Mexico hear a faint sound that scientists have been unable to identify the source of. There’s also NOAA’s list of unidentified deep ocean sounds, only some of which have been solved. So for this week’s Halloween episode, I went down a Wikipedia spiral into unidentified sounds to emerge with this phrase: “Exploding Head Syndrome.”



The condition, as strange as it sounds, is completely legitimate. By piecing together case reports from over the years, doctors have figured out that people with the syndrome hear a sound akin to an explosion as they are falling asleep or waking up. While it doesn’t cause any pain, the condition is associated, in many cases, with enough fear and terror to send some sufferers to the emergency room.



In this week’s episode, I explore the origins of the condition, why it’s definitely real, and why some doctors believe it’s far more common than is reflected in the medical literature. I am definitely a hypochondriac, but I also definitely think I’ve experienced exploding head syndrome. Have you?

Ice technicians are the secret stars of the Winter Olympics

[ad_1] The emphasis of this year's two-week-long Winter Olympic Games has been placed squarely on the Olympians themselves. After all, the stated purpose of the international competition is to bring together the world’s greatest athletes in a nail-biting competition across fifteen different winter sports. But before the curlers, skiers, and skaters even arrived in Pyeongchang, South Korea, the Olympians of the ice technician world were already a few weeks deep in a competition of their own. Mark Callan of the World Curling Federation and Markus Aschauer of the International Bobsleigh and Skeleton Federation both say they’re hoping to make the best ice the Winter Olympics have ever seen. To transform the barren concrete jungle of existing tracks and arenas into an ice- and snow-covered wonderland is an enormous undertaking. And it takes a keen understanding of the physics and chemistry that keeps frozen precipitation pristine. Curling Callan has been making and maintaining ic...

How to avoid the mid-movie bathroom break

[ad_1] Long movies and the urge to pee have been linked since the early days of cinema. Sixty-three years before Avengers: Endgame and its three-hour runtime, moviegoers settled in for nearly four hours of The Ten Commandments . “There will be an intermission,” director Cecil B. DeMille announced during the movie’s introduction. And audiences’ bladders were relieved. On average, movies aren’t getting longer, but they also don’t come with a predetermined bathroom break. That means when nature calls, you’ve got to either sit in growing discomfort or gamble on the best time to run to the restroom. But it doesn’t have to be this way, and for most people, setting your body to “do not disturb” is fairly simple. Go before the show The first piece of advice is also the easiest: pee before the movie starts. Generally, healthy adults urinate every 3-4 hours, so the longer a movie runs, the more urgent it becomes to reset your internal p...

Charted: Here's how much your food waste hurts the environment

[ad_1] Our species is pretty good at wasting food. Some we discard at the farm for being undersized or oddly shaped. Others we allow to decay in their shipping containers, thrown away before they even reach shelves. We leave even more foodstuffs wasting away in grocery stores, often by letting it sit there until it reaches its sell-by date. As consumers, we don’t have much control over most of the process that brings our food to the grocery store, but we do have control over how much food we personally waste. Let's face it: We’ve all found liquified lettuce in our veggie drawers. Don't fret. It's arguably impossible to consume 100 percent of the food we buy. But a healthy reminder of the effect food waste has on the environment might help us all to be more conscious of the amount of food we eat—and don't eat. Consumer food waste varies extensively depending on the area. In South and Southeast Asia, the Food and Agriculture Organization (FAO) estimates that only around ...
