Eggs aren’t just for breakfast, they’re for dessert…in the form of custard, anyway! Pastéis de nata are some of the most famous sweet treats in Portugal. These small, yellow tarts are eggy, creamy, and a little flaky, with a surprisingly religious history.
Pastéis de nata are made with puff pastry dough, pressed into small tart molds. The dough is layered until it's thick enough to hold a generous amount of sweet custard, made from egg yolks, milk, sugar, and flour. The tarts are then baked at a high temperature until the custard is caramelized, giving the tarts a slightly crunchy, sugary top layer. They can be served warm or cold, and are often dusted with cinnamon or powdered sugar.
Pastéis de nata have a well-documented history. In fact, we know the exact building where the tarts were first made: the Jerónimos Monastery in Lisbon, Portugal. In the early 19th century, Portuguese monks and nuns used egg whites to starch their robes and habits, leading to a lot of leftover egg yolks. These yolks were put to use in the monastery and convent kitchens, where they were often used to create baked dishes. Custard was a particularly good way to make use of the yolks since it was versatile and kept well. The tarts created at the Jerónimos Monastery were based on an 18th-century monastery recipe for pastéis de Belém, named after the district in Lisbon where the monastery was located. The recipe slowly morphed into pastéis de nata, which simply means “custard tarts.”
Portugal was forever changed in 1820, when the Liberal Revolution broke out. As the government reorganized, many religious orders were dissolved and monasteries were ordered to close, as some leaders saw them as a waste of money or a danger to secular life. In an attempt to fund themselves, monks at the Jerónimos Monastery began selling their pastéis de nata outside a local sugar refinery not long after the revolution. The tarts became so popular that, although the monastery did close in 1834, the sugar refinery’s owners bought the recipe and opened a bakery called Fábrica de Pastéis de Belém to continue making them. Amazingly, the bakery is still in operation and makes around 20,000 of their famous tarts every day. Clearly, the monks were on to something![Image description: Two small, yellowish custard tarts in metallic pie tins.] Credit & copyright: Wiki Farazi, Wikimedia Commons.

They were handy, but they weren’t exactly apex predators. Homo habilis are thought to be the earliest human species and were once thought to be the first to use tools, hence their name, which means “handy man” in Latin. They were also thought to be the first to reverse the predator-prey relationship, thanks to their tool-making skills. Unfortunately, researchers at the University of Alcalá in Spain have found evidence that they weren’t quite the hunters they were made out to be, according to a paper published in the Annals of the New York Academy of Sciences.
Homo habilis lived between 2.4 million and 1.4 million years ago, and their adults ranged between 40 to 53 inches tall and weighed around 70 pounds. Despite their diminutive size, they were long considered to be more predator than prey. However, that belief might need to be reexamined now that researchers have examined Homo habilis remains from Olduvai Gorge in Tanzania dating back two million years. The researchers compared marks found on the remains to 1,496 images of teeth marks from extant carnivores. Using AI to analyze the marks, they found that many of them were left by leopards. The teeth marks seem to strongly indicate that the hominins were being hunted, rather than simply having their remains consumed by scavengers. It must have been a long, long climb up the food chain.[Image description: A partially-intact homo habilis skull on display at a museum.] Credit & copyright: Daderot, Wikimedia Commons.

FREEWorld History Daily Curio #3158Free1 CQ
It’s not exactly the heist of the century…at least, not this century. Maybe it’s a curse from the pharaoh, or maybe it was just their own fault, but four suspects have been apprehended after they allegedly stole an ancient Egyptian bracelet and melted it down for gold.
The original owner of the jewelry in question was Amenemope, who ruled during Egypt’s Third Intermediate Period around 3,000 years ago. Lasting from 1069 to 525 B.C.E., the Third Intermediate Period began shortly after the death of Ramesses XI of the New Kingdom. The pharaohs of the New Kingdom were in decline due to the increasing influence of the High Priests of Amun, who deemed that a pharaoh was no longer necessary as an intermediate of the gods. Perhaps due to the lessened power of the pharaohs during this time, little is known about Amenemope’s reign. Today, the long-dead king is remembered thanks to his funerary mask, which was discovered at the royal necropolis of Tanis in 1940. Made of solid gold, bronze, and bearing the king’s visage, the mask was found alongside a cache of other undisturbed royal tombs.
One of the many treasures found in the tombs was a gold bracelet with a spherical lapis lazuli bead, which held religious significance. In the ancient Egyptian religion, gold was considered the very flesh of the gods themselves, while the lapis lazuli was their hair. Therefore, covering a funerary mask in gold was more than a show of wealth, and the bracelet would have been an auspicious relic to be buried with. Unfortunately, the meaning of the bracelet and its true value might have been lost on the thieves. According to the police, the bracelet was sold for less than $4,000, and the buyer melted it down to make gold jewelry. 3,000 years of history smelted for trinkets…it’s enough to make a pharaoh (and archeologists) weep.

If it’s brown…watch it chow down! This week marks the return of Alaska’s Fat Bear Week, a cherished annual tradition in which Alaskans vote, tournament-style, on which local brown bear they think is the fattest. This time of year, Alaskan brown bears gain hundreds of pounds, sometimes doubling their body weight. They aren’t in need of a diet, though. They’ve fattened up after gorging on salmon in preparation for winter hibernation.
Brown bears don’t just live in Alaska; they’re also found in other parts of North America, including Canada, Montana, and Wyoming. Even when it isn’t fat bear week, brown bears are pretty enormous. They can be five feet tall when standing on all fours, and up to ten feet tall when standing on their hind legs, which they’re capable of doing with relative ease (though they can’t easily walk on two legs.) Mature, male brown bears can weigh up to 1,500 pounds. Yet, as formidable as brown bears are, they’re not the meat-crazed predators that they’re sometimes portrayed to be. In fact, about 75 percent of their diet consists of plant matter, like wild fruits, berries, and roots. When they do eat meat, they’re not averse to carrion, as their strong digestive systems allow them to break down rotting meat and even bones without issue. Most of the fresh meat they eat comes from fish, especially salmon, which migrate through Alaskan rivers in huge numbers every autumn on their way to spawn.
Brown bears endure the harsh Alaskan winters by hibernating, which involves digging and staying in their underground dens for about seven months out of the year. Yes, these bears spend more time hibernating than not. Hibernation is a lot more complicated than regular sleep, though. Bears enter a deep, sluggish state called torpor in which their breathing and heart rate slows, and their body temperature can drop up to 12 degrees. In this state, they don’t eat or drink, surviving off their fat stores instead. If a bear fails to eat enough in the weeks leading up to hibernation, they can easily freeze to death in their dens.
Amazingly, brown bears give birth while hibernating, nursing their cubs in their dens until they’re strong enough to go above ground. It may seem like odd timing, but it’s actually ideal, since the cubs leave their dens around springtime, just as food is becoming abundant again. The cubs stay with their mothers for around two and a half years, learning to forage and hunt before striking out on their own. It takes a long time to learn the ins and outs of all that hibernating!

Prepare to be a-maized by a maze. It’s officially fall, which means that hayrides, pumpkin patches, and corn mazes are popping up across the country, and some are especially impressive. For the fourth year in a row, the Treworgy Family Orchards in Levant, Maine, has been given the distinction of having the country’s best corn maze, according to USA Today’s 10 Best Readers’ Choice Awards. Amazingly, the seemingly age-old, seasonal tradition of carving mazes into cornfields has only been around since the 1990s.
Treworgy Family Orchards is one of countless farms around the U.S. that opens its fields to the public each autumn. Farms like theirs generate additional revenue by offering apple picking, pumpkin patches, and a chance to traverse a corn maze. The very first corn maze opened to the public in 1993. The story goes that Broadway creative director Don Frantz was flying over some corn fields when he looked out the window and got the idea to create a maze within the stalks of corn. With the help of his friend, Adrian Fisher, a British designer, the first corn maze was created in Annville, Pennsylvania, on a three-acre field by pulling stalks of corn by hand. Like many corn mazes today, the very first one ever featured a whimsical design in the shape of a dinosaur dubbed “Cornelius the Cobasaurus.” The maze itself was named the “The Amazing Maize Maze,” and it was a hit with the public. After the “The Amazing Maize Maze” debuted, it inspired other farmers to try their hands at creating corn mazes of their own. Today, the corn maze is a beloved fall tradition and there are around 500 of them made every year to thrill—and confuse—guests. As for how they’re made, some farmers use GPS to create their designs, while others rely on paper maps and a good sense of direction. Of course, a good sense of direction will also help you have fun in a corn maze…but at least if you get lost, you’ll be surrounded by food.

FREEMusic Appreciation Song CurioFree2 CQ
Some songs have profound lyrics, and others make simple sounds uniquely theirs. Can’t Get Your Out of My Head by Australian pop star Kylie Minogue is definitely in the second category. The song’s most famous words are, undoubtedly, “la la la”, sung in a sultry voice before each chorus. Yet, despite its seeming simplicity, the 2001 pop hit remains Minogue’s most popular song. It topped the UK charts this month in its release year, and its music video, which features nostalgic, early-2000s CGI, won several awards. Can’t Get You Out of My Head is an extremely danceable song, and its easy-to-remember lyrics and electronic sound made it perfect for clubs. While the track helped Minogue achieve fame outside her home country and the UK, it wasn’t originally written for her at all. The songwriting duo of Cathy Dennis and Rob Davis originally penned the track for British pop group S Club 7, whose manager rejected it. It was then offered to British singer Sophie Ellis-Bextor, who also turned it down, before Minogue’s manager said yes. Third time’s clearly a charm!

A zebra might not be able to change its stripes, but a cow can—with a little help, anyway. A group of Japanese scientists have been awarded the Ig Nobel Prize (awards given by the Annals of Improbable Science for unusual and imaginative research) proving that painting stripes on cows can imbue them with the same, fly-repellent powers that zebras possess.
Contrary to popular belief, a zebra’s stripes are not strictly for camouflage. The high-contrast, black-and-white striping does make it more difficult for predators to see a specific zebra’s outline in a herd, but it also confuses flies, preventing irritating bites. In Africa, horse flies and tsetse flies are a constant source of aggravation for the native fauna, as their painful bites can transmit fatal diseases like African horse sickness. As it turns out, this benefit can be conferred onto domesticated cows, who deal with flying pests of their own. The scientists who won the Ig Nobel’s Biology Prize proved this by painting some cows in black-and-white stripes and others in black stripes while leaving some unpainted. The cows were then left where they would be exposed to horse flies, and the cows that were painted black-and-white fared much better than the others. The black striped and unpainted cows received up to 110 bites in 30 minutes, while the zebra-striped cows only received 60 in the same time frame.
Flies don’t avoid stripes because they find them tacky, but because the stripes mess with the flies’ visual perception, preventing them from landing effectively. It’s a simple, low-tech solution to a problem that costs the cattle industry billions each year. Fighting back against the insects usually involves expensive pesticides, which have the additional risk of being toxic to the environment. It might not seem like much, but with millions of cattle all over the world, the losses add up. Flies sure are small to be causing such big problems.

Some artists have more range than others. Samuel Bourne was an English photographer who conducted photographic expeditions to the Himalayas. His piece above, The Manirung Pass, shows seven people walking through a mountain pass. The landscape is covered in snow, and more of the mountain range can be seen in the distance between the peaks. After traveling to India in 1863, Bourne spent seven years traveling the country and photographing everything he saw along the way. His photographs, which numbered around 2,500 by the time he departed the country, became widely popular and were collectively the most thorough visual documentation of India at the time. While in India, Bourne traveled to the Himalayas three times. During his last expedition, he took the above photograph at an elevation of 18,600 feet, setting a new record. The purpose of the last expedition was to reach the source of the Ganges, the Gangotri Glacier. Though they nearly died due to the extreme environment, Bourne’s expedition was successful, to say the least. It’s like he was Bourne for it.

Like resin from a tree, the continents are drifting ever so slowly. It’s fitting, then, that amber is helping scientists learn more about Gondwana, a supercontinent that started to break up around 180 million years ago. Here’s a curious fact about amber: most deposits of the fossilized resin are found in the northern hemisphere. That fact has puzzled scientists for quite a while, and the lack of amber in the southern hemisphere has also been a detriment to paleontologists. That’s because a chunk of amber is almost like a time capsule containing information about the environment it was formed in. Although it resembles stone, amber isn’t a mineral at all, since it’s formed from the resin conifer trees, then hardens over time, turning into copal. Over millions of years, the concentration of essential oils in the resin dissipates, oxidizing the copal and producing amber. Everything from pollen to insects can be caught in amber, where they become known as bioinclusions. Amber bioinclusions can be extremely valuable to scientists, since they’re often lifeforms or substances that don’t fossilize well. No wonder, then, that scientists are so excited about finding insects preserved in amber for the first time in South America. Found in a quarry in a rain forest in Ecuador, the amber contains the preserved remains of several orders of insects, including beetles and ants, as well as pieces of spider webs. Moreover, the pollen and leaves contained in the amber show that the region was once home to ferns and conifers not found there today. In all, the rare amber deposit is proving to be a treasure trove of information about the supercontinent Gondwana, which was made up of South America, Africa, Australia, and several over landmasses. Maybe it’s time we got the gang back together to see what they’ve been up to.

Although it resembles stone, amber isn’t a mineral at all, since it’s formed from the resin conifer trees, then hardens over time, turning into copal. Over millions of years, the concentration of essential oils in the resin dissipates, oxidizing the copal and producing amber. Everything from pollen to insects can be caught in amber, where they become known as bioinclusions. Amber bioinclusions can be extremely valuable to scientists, since they’re often lifeforms or substances that don’t fossilize well. No wonder, then, that scientists are so excited about finding insects preserved in amber for the first time in South America. Found in a quarry in a rain forest in Ecuador, the amber contains the preserved remains of several orders of insects, including beetles and ants, as well as pieces of spider webs. Moreover, the pollen and leaves contained in the amber show that the region was once home to ferns and conifers not found there today. In all, the rare amber deposit is proving to be a treasure trove of information about the supercontinent Gondwana, which was made up of South America, Africa, Australia, and several over landmasses. Maybe it’s time we got the gang back together to see what they’ve been up to.

Bombs away! Prior to the U.S. joining World War II, the U.S. military foresaw the need for a long-range, high-altitude, heavy bomber that could both evade enemy fire and defend itself. Less than a year after the nation joined the conflict, on this day in 1942, the United States Army Air Forces (AAF) introduced the B-29 Superfortress, a bomber unlike any other that—despite its flaws—was one of the most innovative aircraft of its time.
If necessity is the mother of invention, then war is necessity’s greatest sponsor. For better and for worse, military conflicts have always driven the development of industry and technology. In the case of the B-29, the mere possibility of conflict was enough for the AAF to begin development on a new aircraft to meet ambitious demands. As Germany began invading its neighbors, General Hap Arnold of the AAF feared that a German victory would deprive the U.S. of airbases across the Atlantic. The solution, then, was to create a bomber with enough range that it didn’t matter if there were no airbases across the ocean. In 1942, the B-29 debuted with a test run over the continental U.S. after taking off from Seattle. Ironically, when the bomber entered service in 1944, its first mission was in the Pacific theater against Japanese forces, not in Europe. As part of Operation Matterhorn, B-29s operating out of India, China, and other Asian countries bombed Japanese military targets and even their mainland. Eventually, two B-29s would be used in the first nuclear attacks in history. The Enola Gay would drop Little Boy on Hiroshima on August 6, 1945, while Bockscar dropped Fat Man on Nagasaki on August 9.
The B-29 was undoubtedly one of the world’s most devastating weapons, yet it wasn’t without a myriad of flaws that made it dangerous for its own crew. Some of these flaws were due to the aircraft’s ambitious design. One of the things that set B-29s apart from other bombers was that it was pressurized, allowing it to fly higher without forcing the crew to rely on oxygen. Thanks to pressurization, B-29s could fly as high as 40,000 feet, increasing fuel efficiency and avoiding as much fighting as possible, as well as potentially dangerous weather. It was a technology that had only been in limited use until then, and the B-29 was the first mass-produced aircraft to be pressurized. Instead of pressurizing the entire fuselage, however, there were three individual compartments connected by tunnels. Unfortunately, a loss in pressure while someone was in the tunnel could result in them being ejected from the plane. Another flaw was that its engines were prone to overheating and catching fire, leading to many casualties. The reason for this was the shape of the engine, which was made to be aerodynamic. Its odd shape had the unintended consequence of reducing the aircraft’s ability to cool down. Still, the Superfortress did earn its name. The plane was equipped with a radar bombing system and an array of remote-controlled turrets that also used radar to aim with increased accuracy against enemy fighters flying at hundreds of miles per hour. The B-29 wasn’t invincible by any means, but it was less reliant on escort fighters for defense.
For history buffs, the B-29 remains one of the most iconic aircraft of WWII. The plane continued to be used by the U.S. military until the late 1950s, and the innovations that its development pioneered are now commonplace in aviation. B-29s even assisted in the U.S.’s discovery of the jet stream. Japanese meteorologist Wasaburo Ooishi discovered the jet stream and had been studying it since the 1920s, and the Japanese military used that knowledge to send bomb-laden balloons across the Pacific to strike at America's West Coast. The U.S., on the other hand, didn’t discover the jet stream until their B-29s encountered it on some of their missions, where the unexpected bands of winds at high altitude threw off their aims and affected their fuel efficiency. What a way to wander into a new kind of weather.

FREESports Sporty CurioFree1 CQ
You might know how to fly a kite, but does your kite know how to fly you? British kitesurfer Jake Scrace just set a new record by soaring more than 1,500 feet into the air. Scrace set his personal best and world record height of 1,587 feet off the coast of the Isle of Wight, demolishing the previous record of 908.7 feet. Of course, when it comes to kitesurfing, it’s not just about the altitude, but the waves. Kitesurfing, like its cousin windsurfing, was inspired by surfing. The kite looks more like a paraglider, below which surfers stand, holding onto handles, with their feet attached to a board. While surfing has been around for centuries, kitesurfing first began to emerge as a sport after French brothers Bruno and Dominique Legaignoux invented the inflatable kite, which remains the basis of kitesurfing kites to this day. The sport then grew through the 1990s until the first competitive event was held in Maui in 1998. Currently, there are two major types of kite-based water sports: kitesurfing and kiteboarding. The difference? Most people agree that the former makes use of a directional board like in surfing, while the latter uses twin-tip boards like in snowboarding. Either way, it’s impossible to be bored on these boards.
