This wasn’t an April Fools joke, but it almost seems like one. The state of Illinois recently allowed its citizens to vote on a new design for their state flag, and by far the largest share of the votes went to the existing design. Last year, Minnesota voted to adopt a new design for their state flag, and maybe Illinois was feeling a little left out. In the end, the state’s redesign contest came down to 10 finalists, and out of around 385,000 voters, 43 percent wanted to keep the same old-same old.
Illinois originally adopted their flag in 1915, and it's not exactly known for its vexillological beauty. It features an eagle atop a rock and a shield decorated with the stars and stripes with the setting sun in the background. Next to the eagle, a banner shows the state motto—"State Sovereignty, National Union”—and on the rock are two dates. One is 1868, the year the state seal (the eagle design featured on the flag itself) was adopted, and 1818 for when Illinois became a state. While it may seem strange to hold a flag-design contest, Illinois’ current flag was actually chosen via a similar contest in 1915 organized by the Daughters of the American Revolution, and that wasn't even the first time someone tried to come up with a different state flag for Illinois. A few years prior to that contest, a man named Wallace Rice designed a flag featuring blue and white stripes, 20 blue stars, and one white star. The 21 stars were meant to represent the fact that Illinois was the 21st state to be added to the Union, but no matter the symbolism, the flag was never approved by the state legislature. Other flags considered in the past included banners created for the state’s Centennial and Sesquicentennial celebrations in 1918 and 1968 respectively, and those two were also among the 10 finalists in the latest vote. Even with flags, it seems most people agree: if it ain't broke, don't fix it!

This muse has got some moves. In this painting from 1800, French artist Charles Meynier depicted Polyhymnia, one of the nine muses in Greek mythology. The piece above, Polyhymnia, Muse of Eloquence, shows a woman dressed in ancient Greek attire, with her arms outstretched to the left. She stands in front of a chair, behind which is a bust of a bearded man. The daughter of Zeus and Mnemosyne, Polyhymnia was a muse of dancing and geometry. In some legends, she is credited as the inventor of the lyre. Fitting, considering that she is often said to be the mother of Orpheus, the tragic hero known for his skill with the stringed instrument. In line with her association with dancing and the lyre, she is also mentioned in some legends as the muse of song and music. That makes sense. After all, you need music if you want to dance!

FREENutrition Daily Curio #3055Free1 CQ
Here’s a citrus to celebrate. Researchers at Harvard Medical School have discovered that eating citrus might be an effective way to lower the risk of developing depression. Depression is an extremely common condition, yet it can be extremely difficult to treat. Around 290 million people worldwide are thought to suffer from the disorder, and for many of them, treatments aren’t effective. In fact, around 70 percent of those with depression don’t find antidepressants to be effective. However, in recent years, researchers have found a strong link between an individual's gut microbiome and their mental health, and the Mediterranean diet has been found to reduce the risk of depression by almost 35 percent. Now, similar effects have been found in patients who eat at least one orange every day.
Harvard researchers’ recently examined a study known as the Nurses’ Health Study II (NHS2), which began in 1989 and involved detailed interviews with 100,000 regarding their diets and lifestyles. Those who ate a lot of citrus tended to have significantly lower rates of depression compared to those who didn't. Based on the data, just one medium orange every day might lower the risk of depression by up to 20 percent. But it's not the orange that's helping directly. Rather, citrus consumption promotes the growth of F. Prausnitzii, a beneficial bacterium found in the gut. Researchers believe that F. Prausnitzii affects the production of serotonin and dopamine in the intestines, which can make their way to the brain. Serotonin and dopamine are the hormones that are often lacking in people with depression. Apples might keep the doctor away, but it seems that oranges really keep the blues at bay.

Rags to riches is an understatement. Madam C.J. Walker, the daughter of two former slaves, worked her way up the ladder of a prejudiced society to earn enormous riches as an entrepreneur. Today we're celebrating her birthday with a look back at her remarkable career.
As a young black woman living in St. Louis in the 1890s, Walker didn't start out looking for the "next big idea." She was eking out a living for her and her daughter as a washerwoman. It wasn't until she found a job as a sales agent with a haircare company that things started taking off. The role was personal for her, as she suffered from scalp rashes and balding. Plus, her brothers worked in the hair business as barbers.
Walker was successful selling other people's hair products, but employment was getting in the way of her dream. Literally: a man who visited her in a dream inspired her to start her own company, selling hair and beauty products geared towards black women. The Madam C.J. Walker Manufacturing Company, of which Walker was the sole stakeholder, made its fortunes on sales of Madam Walker’s Wonderful Hair Grower. 19th-century hygiene called for only infrequent hair washing, which led to scalp infections, bacteria, lice, and—most commonly—balding. Walker's Hair Grower combatted balding and was backed by Walker's own guarantee that she used it to fix her own hair issues. A marketing strategy focused on black women, a neglected but growing portion of consumers, was a key ingredient for success.
As the business grew, Walker revealed bigger ambitions. “I am not merely satisfied in making money for myself," she said. "I am endeavoring to provide employment for hundreds of women of my race." Her company employed some 40,000 “Walker Agents” to teach women about proper hair care. Walker stepped beyond the boundaries of her business as a social activist and philanthropist. She donated thousands to the NAACP and put her voice behind causes like preserving Frederick Douglass's home and fighting for the rights of black World War I veterans.
It's often claimed that Walker was America's first black female self-made millionaire. But when she passed away in 1919, assessors found out her estate totaled around $600,000. Not that the number matters at all, really; Walker's legacy is priceless. We're guessing the businessmen and women she inspired could more than make up the difference.Rags to riches is an understatement. Madam C.J.

This goal comes courtesy of the Great Lake State. The New York Sirens made hockey history during a recent Professional Women’s Hockey League (PWHL) game, when forward Abby Roque made the league’s very first “Michigan” goal. This difficult style of goal happens when a player picks up a puck behind the net with their stick, lifts it into the air, and shoots it back into the net at a short distance. Roque is a native of (where else?) Michigan. Though the Sirens lost the match 5-2 to the Ottawa Charge, the goal still marks an important moment in women’s hockey, as Michigan goals are exceedingly difficult to pull off. In post game media, Roque was in high spirits as she explained that a Michigan goal had been, well, a goal of hers for a long time. “...it's something that I jokingly say every day when I come to the rink. I'm like, Okay, Michigan today, and I don't actually mean it, but the opportunity presented itself, so I had to try,” she said. Michiganders represent!

You can’t help but catch a whiff as you chow down with this dish. Referring to a food as “stinky” might seem rude, but it’s actually a point of pride for makers of stinky tofu. This Chinese dish’s actual name, chòu dòufu, literally translates to “smelly tofu”, and is lovingly referred to as stinky tofu in English. The dish has gone viral in recent years as influencers descend on Asian food markets to try unusual dishes on camera, but stinky tofu’s history predates the internet by quite a few years. In fact, it’s ancient.
Stinky tofu is, of course, a kind of tofu, which is a gelatinous food made from soybean paste. The paste is mixed with soy milk, then an acidic coagulant is added, causing the milk to curdle, thus producing solid pieces of tofu. Normal tofu has a very mild smell, though it’s great at soaking up the smells and flavors of dishes that it’s added to. Unlike regular tofu, stinky tofu is fermented, and its pungent aroma, which is sometimes compared to that of rotting vegetables, comes from the brine it’s made in. Fermentation is the same process that turns cucumbers into pickles; it involves submerging food into a brine and keeping it in a sealed container until yeast and bacteria create chemical changes that make it taste (and smell) different. Stinky tofu is usually fermented in a brine of veggies like bamboo shoots and greens, meat products like dried shrimp, fermented milk, and spices. While stinky tofu’s flavor is stronger than that of normal tofu, it’s not nearly as overpowering as its smell. The dish is creamy and rich, with a sour, somewhat salty flavor. It can be eaten in many different ways: cold, steamed, or fried. It’s usually served with spicy sauce for dipping.
Stinky tofu dates all the way back to China’s Qing Dynasty, which lasted from 1644 to 1912. Unlike many ancient foods, we actually know who invented stinky tofu: a scholar-turned-tofu-merchant named Wang Zhihe. In 1669, he journeyed to Beijing from his home in Anhui province to try his hand at becoming part of China’s state bureaucracy. However, he failed the official examination for the job, and found himself low on funds after his journey. To keep afloat, Zhihe set up a tofu stand in the city. His bad luck continued, though, and he ended up with a lot of unsold tofu. Rather than let it go to waste, Zhihe fermented the tofu in jars. This new, stinky tofu was a hit, as it stood out from Beijing’s other street food offerings. To this day, stinky tofu is mainly sold as a street food, both at permanent food stalls and at pop up events, like festivals and night markets. It’s especially popular in Taiwan, and is considered by many to be Taiwan’s unofficial “national snack food.” Sometimes, pungency is perfection.

These molecules are long on drama. Long-chain organic molecules recently discovered on Mars are causing quite a stir in the world of planetary science. Discovered by NASA’s Curiosity rover, the molecules are the largest found on Mars to date, and they could be evidence that life once existed, in some form, on the Red Planet.
Curiosity is constantly taking samples of Martian rock, but it can’t send them back to Earth to be analyzed. Instead, the rover has a built-in sample-analyzing lab called Sample Analysis at Mars (SAM). It’s made up of three instruments that can determine the chemical composition of rocks picked up by Curiosity: a gas chromatograph, a quadrupole mass spectrometer, and a tunable laser spectrometer. The samples are heated to over 2,000 degrees Fahrenheit, releasing gases whose chemical composition is then recorded. In a recent rock sample, Curiosity discovered three compounds that are made up of long chains of carbons. These carbon chains are likely the remnants of fatty acids, which are considered some of the building blocks of life.
This doesn’t definitively prove that life once existed on Mars, as fatty acids can also be made through non-biological chemical reactions. Still, this discovery shows that we’ve just scratched the surface when it comes to molecular findings on Mars. For now, we’ll stay curious about what Curiosity will unearth next.[Image description: A starry sky with some purple light visible.] Credit & copyright: Felix Mittermeier, Pexels

This four-sided sighting is rarer than a four-leafed clover. Conservationists around the world were pleasantly surprised when four snow leopards were recently spotted traversing harrowing mountain terrain together in Pakistan. These elusive cats are notoriously hard to spot on camera. Native to Asia, snow leopards live at elevations between 6,000 and 18,000 feet. They thrive in cold, snowy, mountainous terrain, and with only around 6,500 individuals left in the wild, any sighting of them is good news.
For big cats, snow leopards aren’t all that big, weighing between 50 to 120 pounds. Combined with their camouflage and their ability to deftly navigate the most impassable terrain, snow leopards are practically invisible in the mountains. These cats tend to lead solitary lives, with each individual claiming up to 15.4 square miles of territory. Capturing a single snow leopard on camera often involves days or weeks of tracking, so finding four of them together is fairly unheard of. According to the photographer who captured the snow leopards on video in Central Karakoram National Park, the foursome consists of a mother and her three cubs. Aside from being a rare sight, the video is evidence that conservation efforts in Pakistan might be paying off. While snow leopards are proficient predators and have no equal in their natural habitat, that habitat is under threat from climate change, human encroachment, and poaching. These amazing animals are currently listed as "vulnerable” by the International Union for Conservation of Nature (IUCN). That's a welcome improvement from their previous status of "endangered," which was changed back in 2017 after conservationists discovered a calculation error in a 2008 population assessment. Who could blame them for the mistake, considering how elusive snow leopards are?

Conservationists around the world were pleasantly surprised when four snow leopards were recently spotted traversing harrowing mountain terrain together in Pakistan. These elusive cats are notoriously hard to spot on camera. Native to Asia, snow leopards live at elevations between 6,000 and 18,000 feet. They thrive in cold, snowy, mountainous terrain, and with only around 6,500 individuals left in the wild, any sighting of them is good news.
For big cats, snow leopards aren’t all that big, weighing between 50 to 120 pounds. Combined with their camouflage and their ability to deftly navigate the most impassable terrain, snow leopards are practically invisible in the mountains. These cats tend to lead solitary lives, with each individual claiming up to 15.4 square miles of territory. Capturing a single snow leopard on camera often involves days or weeks of tracking, so finding four of them together is fairly unheard of. According to the photographer who captured the snow leopards on video in Central Karakoram National Park, the foursome consists of a mother and her three cubs. Aside from being a rare sight, the video is evidence that conservation efforts in Pakistan might be paying off. While snow leopards are proficient predators and have no equal in their natural habitat, that habitat is under threat from climate change, human encroachment, and poaching. These amazing animals are currently listed as "vulnerable” by the International Union for Conservation of Nature (IUCN). That's a welcome improvement from their previous status of "endangered," which was changed back in 2017 after conservationists discovered a calculation error in a 2008 population assessment. Who could blame them for the mistake, considering how elusive snow leopards are?

You might not expect to run into a big cat in the Great Lake State, but these days, you could! Two cougar cubs were recently spotted in Michigan’s western Upper Peninsula. According to the state's Department of Natural Resources, it’s the first time in more than a century that cubs have been seen in Michigan. It could be an anomaly, or it could be a sign that these big cats are heading back to breed in one of their ancestral homes.
Cougars, also called mountain lions, pumas, or catamounts, are highly adaptable animals, able to live in states with varying terrain, from the mountains of Colorado to the forests of California to Arizona’s Sonoran Desert. They’re the second-largest wild cats in North America, the largest being jaguars. Males can reach lengths of up to eight feet and weigh up to 220 pounds, while females are smaller, reaching lengths of around six feet and weighing up to 140 pounds. While that’s nowhere near the size of big cats like lions or tigers, cougars still pack a mighty punch. Able to reach top speeds of around 50 miles per hour, cougars can chase down enormous animals like moose and elk, then use their powerful jaws and claws to kill their prey. It’s no wonder, then, that hikers in areas with large cougar populations, like Colorado, are advised to be cautious and avoid interactions with the big cats.
Still, humans pose a much greater threat to cougars than they do to us. Michigan is a perfect example of this; at one time, cougars roamed widely throughout the state. The cats were blamed for killing cattle, though, and bounties on cougars became common in the late 1800s, as did trophy hunting. Within a few decades, cougars were completely eradicated in Michigan. Protections have been passed in recent decades that prevent cougar hunting in the state, but until now it seemed that it wasn’t enough to bring the big cats back. Though some adults have been seen in the state in recent years, it was thought that these cougars were passersby, roaming in and out of Michigan from states with healthier cougar populations. Now that cubs have been spotted though, it seems that a breeding population might be making a new home in the Great Lake State. Maybe the environmental protections are paying off. Or maybe the cougars were just nostalgic.

Cults are dangerous at the best of times, and 1995 was not the best of times. On March 20 of that year, a group then known as the AUM Shinrikyo terrorized Tokyo with a series of deadly sarin gas attacks on the city's subway system. The cult, which mixed some aspects of Buddhism and Christianity while emphasizing a series of doomsday prophecies, was seemingly attempting to speed up the apocalypse with their attacks. Now known as Aleph, the cult carried out the attacks during morning rush hour, targeting several different trains and subway lines, leading to 14 deaths and around 6,000 injuries. It’s considered one of the worst terrorist attacks in postwar Japan, and to this day many survivors continue to deal with the health consequences of being exposed to the gas.
Sarin was invented in 1938 and was originally meant to be used as a pesticide. When it was discovered that the gas worked as a deadly nerve agent, some considered using it as a chemical weapon during WWII, but the idea was scrapped. The consequences would have been disastrous, since sarin can taint water supplies and contaminate food in addition to killing people via inhalation. The gas is a deadly neurotoxin that affects the function of muscles and the respiratory system.
Even three decades later, many survivors of the subway attacks experience severe nerve pains, fatigue, dizziness, and other debilitating symptoms. While there are antidotes against the toxin, there is unfortunately no cure or universal treatment available for those who suffer permanent damage. As for the attacks themselves, they were the deadly climax to a series of smaller-scale attacks by members of the cult, one of which claimed eight lives and injured around 500 people. Luckily, many members involved with the attacks—including the leader—were arrested, though the very last suspect wasn't caught until 2012. Better for justice to come late than never.Cults are dangerous at the best of times, and 1995 was not the best of times.
