It wasn’t just a hairdo, it was a hairmust. The queue hairstyle was worn by Chinese men for centuries, but it wasn’t a simple fashion trend. The print above shows two men, one facing away from the viewer and the other toward. The man on the right is wearing a hat and holding a fan, which the other man is examining. Both men have braided hair coming down from their heads. Starting in the 1600s, all men, regardless of class or ethnicity, were required to cut their hair in a style called a queue. The style originates from Manchu warriors, and was introduced when they conquered China and established the Qing dynasty. Men shaved the front and sides of their heads while the renaming hair was grown out and braided. This tradition continued until the early 1900s, when waning imperial influence saw many men forgo the haircut even before the fall of the last Chinese dynasty. That must have been an exciting time to be a barber in China.

FREESocial Media Daily Curio #3163Free1 CQ
Most doctors agree: unless you’re a stooge in a mobster movie, it’s really not better to keep your lips sealed. A recent social media trend is encouraging people to tape their mouths shut while they sleep, much to the chagrin of medical professionals. According to some videos on various social media apps, taping one’s mouth shut at night can improve the quality of sleep and reduce snoring by forcing someone to breathe through their nose. Posters claim that it can lower blood pressure, improve oxygen levels, and confer all the benefits of breathing exclusively through the nose. It’s true that too much mouth breathing can cause dry mouth, which can in turn promote tooth decay and cause sore throats. The problem, though, is that while preventing mouth breathing could be beneficial, the method really matters.
According to actual medical professionals, mouth taping could pose a health risk. While it does force participants to breathe through their noses, it also causes difficulty breathing if there is an obstruction in the nasal cavity, which there often is. If someone can’t breath well through their nose but their mouth is taped, it could lead to a different kind of sleep problem in which one wakes up gasping for air. Thus, doctors advise against anyone suffering from allergies, sinus infections, deviated septums, or nasal congestion from taping up their mouths. Those with heart problems should also refrain from mouth taping, since difficulty breathing can stress the heart. Lastly, even if mouth taping does help someone reduce their snoring, it might just be covering up a problem like sleep apnea. You could call it a sticky solution, at best.[Image description: A dispenser of clear tape.] Credit & copyright: Dnor, Wikimedia Commons.

Traitor, hero or someone who was just in a bind? Iva Toguri D’Aquino, also known as “Tokyo Rose,” was convicted of treason this week in 1949, but she was pardoned for the crime in 1977. Though she was reviled for a long time by the American public as a traitor, she was also vindicated later on. And all of this because she happened to be in the wrong place at the wrong time during WWII.
Iva Toguri was born in Los Angeles, California, on July 4, 1916, to Japanese immigrants. Despite her timely birthday and citizenship, Toguri would go on to become one of the most infamous civilian figures in WWII, even if that reputation was undeserved. Toguri grew up in the U.S. and attended UCLA. Soon after graduating, she traveled to Japan to visit a sick relative. It just so happened that she was traveling with a Certificate of Identification instead of a passport, which wouldn’t have been a problem…if the Japanese Imperial Navy hadn’t attacked Pearl Harbor while she was still in Japan. In the wake of the attack, the U.S. refused to grant her a passport or certify her citizenship, effectively stranding Toguri in Japan. The Japanese government wasn’t any friendlier, declaring her an “enemy alien” after she refused to renounce her American citizenship. Nevertheless, she was able to find work for a while as a typist while taking Japanese language classes. Then, in November of 1943, Toguri was forced to begin working on an English-language propaganda radio show called “Zero Hour” alongside Australian and American POWs.
In some ways, Toguri’s situation was far from unique. During WWII, the Japanese military forced many of its English-speaking prisoners and civilians to work on propaganda broadcasts aimed at the Allies. Zero Hour was aimed at American troops with the intent of demoralizing them. However, it didn’t always go as planned, as was the case with Toguri. Under the shared moniker “Orphan Annie,” Toguri was one of many women who worked as a DJ on the show, all of whom were collectively called “Tokyo Rose” by American listeners. When she was on air, she frequently used slang terms and made double entendres that her Japanese overseers didn’t understand with the purpose of undermining the propaganda efforts. Indeed, according to various accounts, her show had the opposite of the intended effect. Instead of feeling demoralized, American troops actually enjoyed her show, which often featured popular American music of the time. Also while working with the POWs, she smuggled food and other supplies to them whenever she could, though her efforts weren’t recognized for decades. Before she returned to the U.S. in 1947, she married Felipe D’Aquino, but divorced after he was unable to get permission to enter the U.S. with her. As soon as she arrived in the U.S., there was a massive public outcry to prosecute her. Though she wasn’t the only “Tokyo Rose,” she found herself held accountable as the only one. After she was convicted of treason in 1949, she spent six years in prison.
Toguri was pardoned in 1977 by President Gerald Ford thanks to several factors. An investigation into her trial revealed that several witnesses for the prosecution had been coerced into committing perjury. Secondly, her subversive actions against the Japanese military during her time as a propagandist came to light. In recognition of her innocence and her efforts to aid the American POWs, Toguri was awarded the Edward J. Herlihy Citizenship Award by the World War II Veterans Committee in 2006. Toguri passed away that same year, and today she’s remembered mostly as a hero, not a traitor. Is there any better way to be vindicated?Traitor, hero or someone who was just in a bind?

If you can’t believe your eyes, believe the 12 cameras that are recording everything! The MLB has announced that it will adopt the Automated Ball Strike (ABS) Challenge System starting in 2026, and it’s a welcome move for many players. The days of umpires making controversial calls might soon be over as the MLB starts using the ABS Challenge system, which records every pitch with 12 cameras. If a player feels that the umpire has made the wrong call, they can request a challenge to see if the ball was in the strike zone or not. Then, ballpark attendees and viewers at home can watch the footage while officials either correct the call or allow it to stand. The technology has been in use in the minor leagues for some time, but it’s only now making its way to the majors with the support of fans, players, and coaches. While some had concerns that the system would affect the pace of the game, ABS proponents point out that each challenge only takes around 14 seconds to sort out on average. Besides, each team will only get two challenges per game, and players must make the decision themselves without the input of a coach. As if they needed any more pressure at the plate.

This dish is frightfully appropriate for October…considering that it has the potential to kill you. Fugu is a common name for several species of pufferfish in the genus Takifugu, Lagocephalus, or Sphoeroides. It’s also the name of several dishes prepared from these fishes’ meat. What makes the dish unusual is that these fish are extremely poisonous—so much so that incorrect preparation can easily kill an unlucky diner.
Fugu is often served as raw slices, or sashimi. It’s also a common ingredient in nabemono, a hot pot dish where meat, noodles, and veggies are added to broth throughout the meal at the diner’s discretion. Certain parts of fugu contain a toxin called tetrodotoxin, which is extremely dangerous if ingested. Fugu liver, which is commonly said to be the most flavorful part of the fish, is also the most deadly. It has been banned in certain prefectures in Japan and is highly regulated wherever it is allowed.
For a dish that poses such inherent risks, fugu is awfully popular, and it’s been that way for a long time. In fact, people in Japan and Korea have been eating fugu since at least the Jōmon period, some 2,300 years ago. Its history may stretch back even further than that, as there is some archeological evidence that even prehistoric peoples consumed the fish some 4,000 years ago. At the time, fugu were plentiful and fairly easy to catch, making the risks worth it for many people in the region. As time went on, the fish became an expensive delicacy, and some species were driven to near-extinction due to overfishing.
Although fugu is safe to eat when properly prepared, some high-profile poisonings in the past century led to bans and stricter regulations. In 1958, it became illegal for chefs to prepare fugu without a special license. Getting the license is no easy feat: a chef must train for up to three years and pass both written and practical tests. Even grocery stores that sell fugu are required to display licensing documents so that customers know the meat is safe. The fish themselves also enjoy greater protections today in the form of fishing regulations, which helps prevent their wild populations from depleting. Of course, one way to make things safer for both wild fugu and diners is to simply eat farmed fugu. Wild fugu are only poisonous because of a bacteria they consume in the wild, which their bodies convert into toxins. Farmed fugu are kept away from this bacteria, rendering them completely safe. But where’s the adventure in that?

Would you like to go deep sea diving in deep space? According to a paper published in Icarus by scientists at the Planetary Science Institute, one of the moons of Uranus likely had an ocean that was over 100 miles deep. In comparison, the deepest part of the ocean on Earth is only around seven miles deep, while the average depth is around two miles. Ariel, an ice-covered moon and the fourth-largest of Uranus’s satellites, apparently would have put those figures to shame. It’s especially impressive considering that Ariel is only 720 miles wide. Scientists were able to figure out the moon’s history by looking at its surface, which contains telltale signs of the past. After the surface was fully mapped, the scientists used a computer program to model the tidal stresses that would have been necessary to shape Ariel. These would have fluctuated with the moon’s proximity to Uranus in orbit. The deviation in orbit, or eccentricity, was around 0.04 in the past, or about 40 times the current value. By combining the data on the surface of Ariel as it is today with the eccentricity of the past, scientists were able to determine what the moon’s oceans were once like, though they’re still not sure exactly how long ago they existed. Ariel is the second of Uranus’s moons that was found to have once contained large amounts of water. That’s one more than Neptune, which needs to catch up if it wants to live up to its god-of-the-sea name!

One man’s unexploded ordnance is another critter’s treasure. Using an undersea submersible, researchers at the Senckenberg Research Institute in Germany have found that marine life is thriving on what used to be the deadliest weapons in the sea. World War II shaped many aspects of our curent political age, but more tangible and literal remnants of the war can be found at the bottom of the ocean in the form of discarded weapons and unused explosives. It’s estimated that there are currently 1.6 million tons of WWII-era weapons lying in German waters alone. These dumped weapons pose a number of threats. On land, explosives might detonate when disturbed after decades of slumber. That’s less likely underwater, but dangerous chemicals can still leak out as their containers deteriorate, causing harm to people and the environment. It would seem, then, that the deadly refuse of the past would prevent modern day sea life from thriving. Oddly, though, scientists exploring the seabed of the Bay of Lübeck have found that a cache of failed V-1 flying bombs have become an unlikely home for a variety of underwater fauna. V-1 flying bombs were rockets developed by Nazi Germany during WWII with the intention of striking at long-distance targets. Due to their unreliable nature, though, many of them simply ended up crashing into the water before making it anywhere near their targets. Now, starfish, anemone, crabs, marine worms, and other creatures are living on the “metal carcasses” of the rockets, seemingly unperturbed by the undetonated explosives inside. Based on observations made with a submersible, it appears that the twisted metal shell of the rockets has filled with sediment, creating a rich and varied environment for marine fauna to thrive on. Settling down on a fallen bomb? It gives new meaning to the phrase “volatile housing market!”

They didn’t sail with Jason to steal the golden fleece, but they still come by their name naturally! Argonauts are the only octopuses on Earth that have shells, albeit thin ones that are mainly used for reproductive purposes. Though they live in tropical and temperate waters all over the world, they aren’t as well known as some of their cephalopod cousins.
Argonauts are strange-looking, even by octopus standards. They’re quite small, and their size varies greatly depending on their sex. Females are roughly 20 times larger than males. While females can grow up to 15 inches long, males rarely reach a full inch in length. Only female argonauts have a shell, but they aren’t born with it. They create it themselves by secreting a liquid from their frontmost tentacles which quickly hardens. This shell gives them their nickname, “paper nautiluses”, since it makes them look a bit like their nautilus cousins, but unlike nautiluses, argonaut’s “shells” are not true shells. They don’t have valves that allow for water flow and movement, like nautiluses’, and argonauts can’t tuck themselves fully inside their shells to hide. In fact, argonauts’ shells are so thin that they provide little protection. Instead, female argonauts use them like pouches in which to store their eggs. This is a useful thing for them to do since, unlike most octopuses, argonauts don’t live in deep water. That means that they don’t have access to the seafloor caves that most octopuses lay their eggs in. Near the water’s surface, there aren’t many places to hide eggs, hence their shell solution.
Argonauts’ shells serve another important function. They help keep the females afloat, even when they’re burdened with eggs. They do this simply by trapping air, like a lifejacket. Without their shells, female argonauts wouldn’t be able to stay near the water’s surface, which would be a big problem since they can’t survive in colder, deeper waters.
Like all octopuses, argonauts are predators, though they’re not fast enough to catch fish the way that larger species do. Instead they feed mainly on mollusks, jellyfish, and salps that drift by in open waters. Their shells may be (somewhat) hard, but that doesn’t mean they have to work hard.

Even a short tenure can have a lasting impact. Pope John Paul I, also known as “the Smiling Pope,” passed away around this time of the year in 1978, just 33 days after becoming the pope. This brief pontificate (the term referring to the tenure of a pope as well as the position itself) is one of the shortest in history. Born on October 17, 1912, in Forno di Canale, Italy, with the birth name Albino Luciani, Pope John Paul I was ordained a priest in 1935. He was elected pope on August 26, 1978, and he was unique in a number of ways.
Pope John Paul was one of the few pontiffs to have a pastoral reputation, despite never serving as a pastor, and was known for being accessible as a result. Even his nickname comes from the ever present smile on his face, which endeared him to the public. He was also the first pope to be born in the 20th century, the last to die in the 20th century, and—as of now—the last Italian pope to be elected. He was the first pope to have two names; “John” and “Paul” refer to Popes John XXIII and Paul VI.
As short as his pontificate was, it’s not the shortest ever. That “honor” goes to Pope Leo XI, who passed away in 1605 just 27 days after becoming the pontiff. Pope John Paul I passed away in his sleep, presumably of a heart attack, though the exact cause was never officially established. Due to the sudden and unexpected nature of his death, there were unsubstantiated rumors at the time that he had been assassinated. Decades after his passing, he was beatified and became Blessed John Paul I, meaning that he is at the second stage on the way to becoming a saint. The beatification came after an 11-year-old girl in Argentina with Febrile Infection-Related Epilepsy Syndrome reportedly recovered after praying to the pope. Even in death, his reputation keeps improving![Image description: An illustration of the obelisk in front of the Vatican.] Credit & copyright: The Vatican Obelisk, from "Speculum Romanae Magnificentiae" Publisher: Antonio Lafreri (French, Orgelet, Franche-Comte ca. 1512–1577 Rome).

Even a short tenure can have a lasting impact. Pope John Paul I, also known as “the Smiling Pope,” passed away around this time of the year in 1978, just 33 days after becoming the pope. This brief pontificate (the term referring to the tenure of a pope as well as the position itself) is one of the shortest in history. Born on October 17, 1912, in Forno di Canale, Italy, with the birth name Albino Luciani, Pope John Paul I was ordained a priest in 1935. He was elected pope on August 26, 1978, and he was unique in a number of ways.

FREEMusic Appreciation Song CurioFree2 CQ
You could say that this song had a “fair” showing! On this day in 1995, British pop band Simply Red scored their first and only number one hit in the UK with Fairground. Despite a fast samba beat sampled from Dutch electronic music duo The Good Men and a music video with bright, flashy cars and roller coasters, Fairground has calm, echoey vocals and lyrics about love. Strangely, despite staying atop the UK charts for around four weeks, Fairground never achieved significant success in the states. The group did have two number one hits in the U.S., 1986’s Holding Back the Years and 1989’s If You Don’t Know Me By Now (a cover of a 1972 hit from Harold Melvin & the Blue Notes) but both songs peaked at number two in Simply Red’s native England. It seems that even when you can please everybody, you can’t always do it at the same time.

FREEScience Daily Curio #3160Free1 CQ
Is the nuclear option the only option? When asteroid 2024 YR4 was first discovered,there were concerns that it might crash into Earth. Now, scientists say that it’s more likely to strike the moon, but that doesn’t mean there won’t be any consequences. The solution, some say, is to strike first.
2024 YR4 was discovered back in December of 2024, and it initially raised some serious alarm bells. At the time, it was thought that there was a 3.1 percent chance of it crashing into Earth, which could have had devastating consequences. Although the asteroid is only about 180 feet wide, that still would have been enough to destroy an entire city. Fortunately, the odds of 2024 YR4 hitting Earth has been recalculated to be around 0.28 percent, or around one out of 360. Unfortunately, it appears that it now has around a four percent chance of hitting the moon instead, and that could have negative effects here on Earth too.
If the asteroid were to strike the surface of the moon, it would send a massive amount of debris, known as lunar “ejecta”, into space. All that debris will most likely head toward Earth, and while it’s unlikely that any of it would cause significant damage to our planet’s surface, it could wreak havoc on everything in its orbit. In essence, a veritable storm of micrometeoroid debris could knock out satellites and any spacecraft in orbit at the time. Although it’s never been done before, scientists at NASA believe that it’s possible to send a spacecraft like DART to deliver a nuclear bomb if it’s launched before 2032, when the asteroid will be nearby. The DART mission back in 2022 used a kinetic impactor to alter the orbit of the moonlet Dimorphos around the parent asteroid Didymos, so it’s definitely possible to land a spacecraft on 2024 YR4. The only issue is that a nuclear bomb has never been used in this way before. It’s theoretically possible, but completely untested. Is it work duking it out via nuke?Is the nuclear option the only option? When asteroid 2024 YR4 was first discovered,there were concerns that it might crash into Earth.
