The Beale Ciphers - Virginia

In the early 1800s, three coded papers surfaced, said to reveal the location of a hidden treasure in Virginia . Only one cipher (the second) has been partially decoded using the Declaration of Independence, pointing to a stash of gold, silver, and jewels.

Treasure hunters and cryptographers have tried for decades to crack the remaining ciphers. Yet, so far, no one has succeeded.

The Georgia Guidestones - Georgia

Erected in 1980, the granite monument carried inscriptions in multiple languages , laying out guidelines for humanity’s future. The massive slabs earned the nickname "America’s Stonehenge."

The mystery lies in who commissioned it. The sponsor used a pseudonym and never revealed their identity. Too bad they were destroyed in 2022 after being damaged by an explosion.

The "Wow!" Signal - Ohio, 1977

One night in 1977, Ohio State University’s Big Ear telescope picked up a deep-space radio burst lasting 72 seconds . Astronomer Jerry Ehman circled it and wrote "Wow!" beside the data.

The signal has never been definitively explained. Whether it was a passing comet, a reflection, or something else, no one knows.

Roanoke Colony’s "CROATOAN" - North Carolina

In the late 1500s, settlers on Roanoke Island disappeared, leaving only the word "CROATOAN" carved on wood . Their fate remains one of the earliest American mysteries.

Some think they merged with local tribes, while others suggest they relocated. Without proof, the vanished colony remains a puzzle historians love to revisit.

5

The Taos Hum - New Mexico

Since the 1990s, some residents of Taos report hearing a low, steady humming sound . It’s described like a distant diesel engine idling in the desert.

Some studies suggest it may be related to low-frequency industrial noise or tinnitus in some individuals. The reality is, scientists have studied the phenomenon but haven’t pinned down a cause.

6

Marfa Lights - Texas

Out in West Texas, glowing orbs have appeared on the horizon for generations . They shimmer, split, and move in ways that seem inexplicable.

Tourists flock to Marfa hoping to catch a glimpse. Some suggest car headlights or atmospheric tricks, but the mystery remains.

7

Bloop-Like Ocean Sounds - Pacific Ocean

In the 1990s, NOAA hydrophones picked up a booming, low-frequency sound in the Pacific Ocean . Nicknamed "the Bloop," it was louder than known whale calls.

Theories ranged from icequakes to giant sea life. NOAA later concluded the sound was likely caused by large icequakes from Antarctic ice breaking apart.

8

The Upton Chamber - Massachusetts

Hidden in Massachusetts is a stone tunnel leading to a small underground chamber . Its age and purpose are still debated.

Some believe it was a colonial root cellar, while others argue it predates settlers entirely. Without records, the chamber remains an enigmatic piece of New England history.

9

America’s Stonehenge - New Hampshire

This site features stone walls, chambers, and standing slabs . Some argue it was built by Native Americans, while others see evidence of pre-Columbian visitors.

While some alternative theories suggest ancient origins, most archaeologists believe the structures are from the colonial-era. Whatever its origin, it’s a fascinating stop for curious travelers.

10

The Great Serpent Mound - Ohio

In southern Ohio lies a massive prehistoric earthwork shaped like a winding serpent . Stretching over 1,300 feet, it curves and coils across the landscape in striking detail.

Scholars agree it was built by Indigenous peoples, but its purpose is unclear. Some suggest it was a ceremonial site or calendar, while others see cosmic symbolism.

11

The Blythe Intaglios - California

Etched into the Colorado Desert, these giant figures depict humans and animals , some over 170 feet long. They’re best seen from the air, raising questions about how and why they were made.

Created centuries ago by Native Americans, their exact age and purpose remain uncertain.

12

Judaculla Rock - North Carolina

This large boulder is carved with hundreds of mysterious petroglyphs . Shapes, lines, and symbols cover its surface, their meanings long lost to time.

The Cherokee connect the markings to Judaculla, a legendary giant. Whether the rock was a sacred site, a map, or something else, the exact meanings of many carvings remain unknown.

It was invented in Switzerland

While the name suggests a US origin, the technology that created American cheese actually began in the heart of the Alps. It was developed in 1911 by Swiss researchers Walter Gerber and Fritz Stettler, who were looking for a way to extend the shelf life of their country’s famous Emmental cheese.

The problem with traditional cheese is that it eventually dries out, molds, or separates into a greasy mess when heated. By shredding the cheese, adding sodium citrate, and heating it, the Swiss duo discovered they could create a stable, smooth product that didn't separate. While they weren't trying to create "American" cheese as we know it today, their emulsification process laid the foundational science for every single-wrapped slice produced today.

2

It was popularized by a Canadian

The man responsible for the global dominance of American cheese was James L. Kraft. Ring any bells? Kraft was a Canadian immigrant who moved to Chicago in 1903. While he didn't invent the concept of processed cheese, he perfected the industrial scale of its production and marketing.

Kraft noticed that retailers struggled with cheese spoilage; if a wheel of cheddar didn't sell quickly, it was a total loss. He experimented with various methods of heating and blending cheese until he found a formula that could be canned and shipped long distances without spoiling. In 1916, he received a patent for his "processed cheese," and during World War I, the U.S. government purchased millions of pounds of it for soldiers, cementing its privileged place in the American diet.

3

It was almost called "Embalmed Cheese"

When processed cheese first hit the market, it had its detractors. Traditional cheesemakers were horrified, and so were pure food advocates. These critics argued that the product shouldn't even be called cheese. They’ve even gone so far as to call it "embalmed cheese" because of its unnaturally long shelf life and the chemical emulsifiers used to keep it stable. Yet, Kraft’s marketing prowess and the sheer convenience of the product ultimately won the naming battle. At least in the court of public opinion.

4

Technically, it isn’t cheese

Kraft may have won the battle among the people, but legally, American cheese is not considered cheese. If you look closely at the packaging, you will rarely see the word "cheese" on its own. Because of strict FDA regulations, most varieties are legally classified as "Pasteurized Process Cheese Product" or "Pasteurized Process American Cheese Food."

To be labeled "cheese," a product must be made primarily of milk, salt, and enzymes. Processed American cheese, however, is made by blending real cheese—usually cheddar or Colby—with emulsifying salts, whey, and sometimes extra milk or fats.

5

Any cheese can be made into American cheese

The term "American cheese" refers more to a process than a specific flavor. In theory, you could make "American-style" brie, blue cheese, or parmesan. The defining characteristic is the addition of an emulsifier, which breaks down the proteins and allows the fats and water to stay together.

In fact, some high-end chefs now make their own artisanal American cheese with aged cheddars processed with sodium citrate to create a slice that has the complex flavor of an expensive block but the melting point of a Kraft Single.

6

It isn’t naturally yellow

The vibrant orange-yellow hue of American cheese is entirely a cosmetic choice. Traditionally, cheese color varied by the season; when cows ate fresh grass in the summer, their milk contained more beta-carotene, leading to a naturally yellowish cheese. To make their cheese look high-quality all year round, cheesemakers began adding dyes.

American cheese takes this tradition to the extreme. It is typically colored with annatto, a seed from the achiote tree. Without this dye, American cheese would be a pale, creamy white, which is how it is sold in many delis as "White American". Yes, that’s right, there is no flavor difference between the white and yellow versions.

7

It has an extremely low melting point

The scientific superpower of American cheese is its meltability. Traditional cheeses have a protein structure that tightens when heated, which is why a slice of aged cheddar on a burger often results in an oily puddle and a rubbery clump.

Because of the emulsifying salts, the proteins in American cheese can withstand heat without clumping together. This gives it an incredibly low and stable melting point, transforming the slice into a silky sauce. This is why it remains the undisputed king of grilled cheese sandwiches.

8

It’s been in space

When you're hurtling through orbit in a cramped capsule, you need food that is stable, easy to eat, and won't crumble into thousands of tiny, electronics-clogging pieces. American cheese fit the bill perfectly for early NASA missions.

Processed cheese in tubes or cubes was a staple of the Apollo missions. Because it doesn't separate or sweat oil in varying temperatures and pressures, it was one of the few dairy products that could reliably provide flavor and calcium to astronauts.

9

It helped bring cheese to the masses

Before the advent of processed cheese, cheese was often a seasonal luxury. It was difficult to transport, expensive to store, and highly variable in quality. James L. Kraft’s invention changed that. By creating a product that was uniform in flavor and shelf-stable, he made cheese affordable and accessible to every corner of the United States.

10

The U.S. Government once gave it out

The U.S. government not only bought tons of American cheese during World War I. In the 1980s, the term "government cheese" became a thing. During a period of dairy surpluses, the government bought millions of pounds of cheese to prop up prices for struggling farmers.

To avoid letting it rot, the Reagan administration began distributing five-pound blocks of cheese to low-income families, seniors, and schools. For many who grew up in that era, that pale orange processed cheese was a lifesaver.

An official pirate license

If being a pirate was your childhood dream, it's more attainable than you think. The main obstacle? Getting into MIT. Once you’re in, you can get your official pirate license —parchment certificate included— provided that you complete four physical education courses in pistol, archery, sailing, and fencing. However, the school has stated that this certificate does not give a license to engage in piracy or any pirate activities.

2

The lethal library

If you’re a bibliophile attending Yale University, be aware that your love for books might get you killed while on campus. To protect its manuscripts and rare specimens, the Yale Beinecke Rare Book and Manuscript Library is equipped with a fire safety device that, instead of sprinkling water, sucks all the oxygen out of the building . The official stance is that this device is not lethal for humans, but that remains unproven.

3

The Olympian factory

American colleges and universities are known for their rigorous athletic programs, but no one does it like Stanford. Did you know that since 1908, there has been a medalist who attended Stanford in every Summer Olympic Games? With a grand total of 335 medals (162 gold, 93 silver, and 80 bronze), if Stanford were a country of its own, it would rank in the top 20.

4

The deceiving statue

Visitors of Harvard University have most likely come across the famous John Harvard statue on campus. However, this statue is so deceptive that it is dubbed ‘the statue of three lies’. What are these lies? The inscription reads "John Harvard. Founder. 1638‍". Harvard University, founded in 1636, not 1638. It owes its name to its first benefactor, John Harvard. It was not founded by him, but by the authorities of the Massachusetts Bay Colony. Additionally, the man represented in the sculpture is not John Harvard, but a student chosen as a model because there were no surviving portraits of Harvard.

5

The inventors of the open curriculum

The open curriculum has been adopted by many institutions nationwide, but Brown University was the blueprint. During the 1950s, they developed the first interdisciplinary courses to avoid stifling intellectual curiosity. By the 1960s, Brown students pushed for the elimination of the standard general education requirements altogether, an initiative that was resisted but eventually implemented by the administration.

The college that was the capital of the U.S.

Before Washington, D.C., was established as the capital of the U.S., several places were temporary capitals, including Philadelphia, New York, and Princeton University in Princeton, NJ. From June to November 1783, the Continental Congress gathered in the college library in Nassau Hall, which made the place the de facto capital of the nation . Among other historical events, the library was where Congress received in 1783 the news of the signing of the Treaty of Paris, which effectively ended the American Revolutionary War.

7

The inclusion pioneers

The desegregation of education was a key element in the fight for civil rights, and Oberlin College, in Ohio, was a pioneer. In 1835, the college made history by enrolling Black students, decades before other major institutions . Besides this, Oberlin was the first to enroll women in 1833 and to admit them to bachelor's degree programs in 1837.

8

Unable to swim? Unable to graduate

Up until recently, students at the University of North Carolina at Chapel Hill had to fulfill a strange requirement in order to graduate. They had to pass a mandatory swimming test , consisting of diving in the deep end, swimming 50 yards, and treading water or floating for 5 minutes. During WWII, the university was used as a training center, and the swimming test was mandatory for recruits. Eventually, this requirement became extensive for all students and was not abolished until 2006.

Computer science pioneers

A modern university offering a computer science program is nothing strange, unless they’re doing it a mere two decades after the invention of the first modern electronic computer. In 1962, Purdue University in Indiana was the first to establish a department of computer sciences , pioneering academic research in the field. More than 50 years later, Purdue University remains one of the leaders in computer science research.

10

The largest student body

Other institutions might boast about being the oldest or the most sought-after university, but Arizona State University leads the rankings when it comes to enrollment . With nearly 80,000 in-person students across the Phoenix metropolitan area campuses and nearly the same number of online attendees, it surpasses all American institutions in terms of student body size. In comparison, Deep Springs College, in California, sits at the opposite end of the spectrum, with a student body restricted to 26 undergraduates.
