Deciding when to observe holidays isn’t always an exact science. George Washington wasn’t born on the third Monday of February, for example. Memorial Day’s precise date on the calendar shifts from year to year (it’s always the final Monday of May, in case you’d forgotten), but at least the reasoning behind it is sound: The late spring date was chosen because it was when flowers would be in full bloom. Since adorning the graves of fallen soldiers with wreaths was once the most important part of the holiday, it’s difficult to imagine Memorial Day taking place at another time of year — especially considering that it was first celebrated in the 1860s, when floristry wasn’t quite as commercially developed as it is today.

Memorial Day has always been called that.

Oops, incorrect!

It's a fib

It was originally known as Decoration Day, due to the fact that graves were decorated with flowers. By the late 19th century, as the holiday became more widespread, the name Memorial Day gradually replaced the original moniker.

Certain aspects of the holiday’s origins are murky, but we know that in the wake of the Civil War, many different communities around the country decorated the graves of dead soldiers with blossoms and said prayers. In 1868, General John A. Logan, who led an organization for Northern Civil War veterans, chose May 30 “for the purpose of strewing with flowers, or otherwise decorating the graves of comrades who died in defense of their country during the late rebellion, and whose bodies now lie in almost every city, village and hamlet churchyard in the land.” Originally set aside specifically for the Civil War, Memorial Day came to encompass all military casualties during World War I. And while initially it was celebrated on a state and community-wide basis, it became an official federal holiday in 1971.

More than 20 towns claim to be Memorial Day’s birthplace.

Only one of them is recognized as such, however: Waterloo, New York. President Lyndon B. Johnson made it official with a 1966 proclamation that also recognized the centennial of its first observation of Memorial Day, which took place in the town on May 5, 1866. According to Richard Gardiner, co-author of The Genesis of the Memorial Day Holiday in America, however, no such celebration took place in 1866, and Waterloo’s claim to the title is dubious — not that it’s at risk of being taken away. Other towns with their own claims of being the holiday’s birthplace include Boalsburg, Pennsylvania; Carbondale, Illinois; and both Columbus, Mississippi, and Columbus, Georgia, among many others.

The animal kingdom is full of incredible variety, thanks to evolution, but one thing most animals have in common is that they use a set of eyes to navigate the world around them. But even the pupil of the eyeball, the biological aperture responsible for how much light enters the eyes, is nearly as diverse as the types of birds that soar the skies or fish that swim the seas.

Humans can’t keep their eyes open when they sneeze.

Ready to reveal?

Oops, incorrect!

It's a fib

Most people experience an automatic response to close their eyes when sneezing, but it is possible to keep them open (your eyes won’t pop out either). Scientists think the response keeps irritants, which the sneeze just expelled, from reentering the body through the eyes.

For mammals, one big factor determining the shape of a pupil is whether the creature is predator or prey. For example, a goat is a grazing prey animal that would be a pretty easy target for coyotes, bears, and other predators with sharp teeth. Yet evolution gave the goat a few tools to defend itself. The horns certainly help, but the biggest advantage is a goat’s horizontal rectangular pupils. These long, horizontal pupils create a panoramic view that lets the animal see more of the landscape, which makes it harder to sneak up on them. The pupils also enhance the image quality of objects (read: threats) all around the goats, and they cut down on glare from the sky by capturing less light from above and more from below. Cats and snakes, on the other hand, are ambush predators, whose vertical pupils help them hunt in the night and judge the distance between themselves and their next meal. But according to scientists, vertical pupils are reserved only for animals whose eyes are close to the ground. That’s why other cats that are higher up, like lions and tigers, have round pupils rather than vertical ones.

Goats have accents.

A 2012 study from Queen Mary University of London revealed that kids (the goat kind, not the human kind) altered their bleating when socializing with other goats. The ability to change one’s voice in response to a social environment is known as “vocal plasticity,” and humans display an extreme form of this concept — it’s how we can develop accents. Goats develop similarly distinct accents based on their social group, admittedly with a more limited vocabulary. In the study, scientists analyzed 1-week-old goats compared to 5-week-old goats; the latter is about the time goats form social groups known as “crèches.” They found that young goats raised in the same crèches developed similar bleats, altering their noises to fit in their social group as they aged. It’s also possible these accents help goats identify members of their group, an idea familiar to anybody who’s traveled outside their home country — or even their hometown.

At 3:45 p.m. on September 9, 1947, a computer programmer working on the Mark II at Harvard recorded in a logbook that the team had discovered the “first actual case of [a] bug being found.” But the programmer wasn’t referring to some poorly written lines of code — this was an actual bug. A moth, to be exact, which had flown into a room where the Mark II, one of the world’s first computers, was housed at the university. Attracted by the warmth of the 25-ton machine, the winged creature met its end in one of the many electromagnetic relay contacts. The team removed the moth with tweezers.

Nikola Tesla was the first to coin the engineering term “bug.”

American inventor Thomas Edison made several references to “bugs” in his notebooks in the mid-1870s, defining them as “bug — as such little faults and difficulties are called.” By 1889, newspapers reported on how Edison was hard at work fixing a “bug” in his phonograph.

While this event is often mistakenly cited as the birth of the programming term “bug” to mean a flaw or imperfection, the word had actually been used in engineering circles for over half a century. But the 1947 moth misadventure was popularized by Grace Hopper, a mathematician and computer science pioneer who worked with the team as they “debugged” the Mark II. Early computers such as Harvard’s Mark series were responsible for other modern computer programming lingo, though: For example, a “patch” comes from the punched cards used in early machines that programmers physically “patched” with tape to fix errors. Today, the original Mark II logbook — with the original “bug” taped to it — is at the Smithsonian Museum of American History

“Spam” took on the additional meaning of junk email thanks to a sketch by the British comedy troupe Monty Python.

Unfortunately, the proprietor of the establishment serves a very Spam-heavy menu, including “Spam Spam Spam Spam Spam Spam Spam baked beans Spam Spam Spam and Spam.” Originally airing on Monty Python’s Flying Circus in 1970, the sketch later became associated with annoying floods of data, ads, or massive amounts of useless text. The word likely first appeared online in late 1980s MUDs (multi-user dungeons), where users could “spam the database” by using a program to create lots of objects in the shared digital space, among other pesky, repetitive behaviors. By 1990, archived MUD chats show that the use of the term “spam,” along with its sketch comedy origins, had been officially established.

Popping an afternoon snack of popcorn in the microwave generally isn’t a messy affair, considering most popcorn cooking is contained to a bag. But if it weren’t, you might have to watch out for flying kernels, since popcorn can pop as high as 3 feet while it transforms from kernel to puff. However, the tiny grains don’t just fly straight skyward as they expand; high-speed recordings of popcorn as it cooks show that the kernels actually flip like a high-flying gymnast, thanks to starches that push off a cooking surface and propel the corn into the air. 

All corn can be used for popcorn.

Ready to reveal?

Oops, incorrect!

It's a fib

Farmers divide corn species into six major types, including dent (used for animal feed), sweet (eaten at dinner tables), and flour (ground into the baking ingredient). All corn is generally grown the same way, but only one type pops when heated: popcorn, aka Zea mays everta.

The way popcorn transforms from a hard nugget to a soft and springy morsel can seem like magic, except scientists say it’s really just a trick caused by heat and pressure. Each kernel has three parts: the germ (seed) found deep within the shell, the endosperm (a starch section used to nourish the germ if planted), and the pericarp (aka the hard exterior). Moisture and starch are also packed into each tiny kernel; when heated, that microscopic amount of water creates pressurized steam. By the time a popcorn kernel reaches 350 degrees, the pressure is too much to contain and the pericarp explodes, causing the starchy endosperm to expand outward. When the process is finished, the resulting popcorn has puffed up to 40 times its original size.

While the popcorn industry strives to get 98% popability from each bag of kernels, there’s likely still going to be duds at the bottom of the microwave bag. In those cases, it’s likely the pericarp was cracked or the kernel didn’t have enough internal moisture, both of which prevent any pressure buildup — which means that no amount of extra microwaving will give you a few more bites.

Popcorn pops into two distinct shapes.

When popcorn is all lumped together in a bowl, it just looks like … popcorn. But an up-close inspection shows that kernels actually pop into one of two shapes, transforming into “butterflies” and “snowflakes” (winged, multifaceted shapes) or “mushrooms” (rounded puffs). Butterflies occur when the popped kernel turns inside out, while mushrooms are created when the kernel’s endosperm expands instead of flipping. Generally, mushrooms are sturdier and can withstand the additional cooking process to become caramel or kettle corn. Whether your bowl of popcorn gets more mushrooms or butterflies mostly depends on factors uncontrollable from your kitchen, like the popcorn plant’s genetics or how much water the plant received while it was growing in the field.

Taxes fund many of the services we need, but no one enjoys paying them — and it’s likely that many of our ancestors didn’t, either. Governments worldwide have levied taxes for thousands of years; the oldest recorded taxes date to before 3000 BCE. But England — which relied heavily on taxes to fund its military conquests — is known for a slate of fees that modern taxpayers might consider unusual. Take, for instance, the so-called “window tax,” initially levied in 1696 by King William III, which annually charged citizens a certain amount based on the windows in their homes. Some 30 years before, the British crown had attempted to tax personal property based on chimneys, but clever homeowners could avoid the bill by temporarily bricking up or dismantling their hearths and chimneys before inspections. With windows, assessors could quickly determine a building’s value from the street. The tax was progressive, charging nothing for homes with few or no windows and increasing the bill for dwellings that had more than 10 (that number would eventually shrink to seven).

Britain taxed soap.

Oops, incorrect!

It's a fact

The British government taxed many everyday items, including salt, candles, and beer. But its 1643 tax on soap created a lather among soapmakers and drove up prices for shoppers — many of whom turned to French soap-smuggling rings for the lower-cost suds they needed.

Not surprisingly, homeowners and landlords throughout the U.K. resented the tax. It didn’t take long for windows to be entirely bricked or painted over (much like fireplaces had been), and new homes were built with fewer windows altogether. Opponents called it a tax on “light and air” that hurt public health, citing reduced ventilation that in turn encouraged disease. Even famed author Charles Dickens joined the fight to dismantle the tax, publishing scathing pieces aimed at Parliament on behalf of poor citizens who were most impacted by the lack of fresh air. Britain repealed its window tax in July 1851, but the architectural impact is still evident — many older homes and buildings throughout the U.K. still maintain their iconic converted windows.

The United States had its own (short-lived) “glass tax.”

Just two decades after declaring independence from Britain, the U.S. was in need of funds to bolster its military — this time in preparation for potential conflict with France. President John Adams knew that building up troops wasn’t a cheap initiative and that the country would need to raise the money somehow. That’s why Congress passed the 1798 U.S. Direct Tax (more commonly called the “window tax” or “glass tax”) with the goal of adding $2 million to its coffers. Each of the 16 states was responsible for assessing the property of its residents; homes and property worth more than $100 were taxed. Considering the cost of pane glass during the late 18th century, buildings with glass windows could quickly reach that cap even if they were modest in size, hence the tax’s nickname (although windows were not directly taxed as in Britain). The tax was controversial and repealed just a year later, but some records still exist, giving genealogists and historians a glimpse into how early Americans lived.

Ever noticed the little vertical groove running down the center of a dog’s nose, connecting the tip of the nose to the upper lip? This narrow groove has a name: It’s known as the philtrum, which is also the word for the vertical groove that stretches from the base of the nose to the upper lip on human faces.

Human philtrums develop in the womb as the face forms, but they have no known function. For our furry friends, though, the philtrum serves an important and fascinating biological purpose. Every time a dog licks its lips or nose — which they tend to do quite a lot — a small amount of saliva collects in this narrow channel. 

In 1989, a Labrador retriever named Max single-handedly flew a light aircraft from London to Paris.

Ready to reveal?

Oops, incorrect!

It's a fib

No dog has ever piloted a plane all the way from London to Paris, but a British rescue dog named Shadow did learn how to fly a light aircraft, successfully completing a (deliberate) figure-eight maneuver at 3,000 feet in 2016.

Through a process called capillarization or capillary action (the same process that allows water to climb up the roots and stalks of plants), the saliva is gently moved up toward the nose pad, aka the leathery skin at the very tip of a dog’s muzzle. This helps keep a pup’s nose nice and moist — because a wet snout is much better at capturing scent molecules from the air. 

The moisture helps to trap, dissolve, and hold on to odor particles so a dog’s 300 million or so olfactory receptors can efficiently analyze all the wonderful smells that permeate its environment. So when your very good boy or girl gives you a big kiss and immediately licks their nose, they’re not just being adorable — they’re instinctively topping up the moisture in their philtrum so they can better understand the invisible world of smells around them.

Some ants smell like chocolate when they’re angry.

Ants outnumber humans by a huge margin, with an estimated 20 quadrillion scuttling around at our feet. But have you ever smelled one? If so, you may have been surprised by the aroma. When angered, threatened, or squashed, many species of ants release potent chemicals that have distinctive smells. The species Tapinoma sessile, for example, is said to smell like rotting coconut, blue cheese, or turpentine when crushed, accounting for its unflattering common name: the odorous house ant, or stink ant.

But not all ants release unpleasant odors. The appropriately named citronella ant, for example, gives off a lemony odor when threatened or crushed. And then there’s Odontomachus, commonly known as the trap-jaw ant. In those same perilous situations, trap-jaw ants release a pheromone that warns other ants of nearby threats — but to humans, it smells like chocolate.

Nearly every cell in your body holds a remarkable amount of DNA. If you could carefully unwind every DNA strand from all your cells and place it end to end, it would stretch roughly 197 trillion to 243 trillion feet (60 trillion to 74 trillion meters). That’s enough to travel from the sun to Pluto and back around 10 to 12 times, depending on Pluto’s position in its orbit. The distance between Pluto and the sun is 39 astronomical units, and one astronomical unit equals roughly 491 billion feet or 150 billion meters.

The first successful animal cloning experiments were actually done on frogs in 1952. In 1996, Dolly became the first mammal cloned from an adult cell.

This estimate comes from the fact that a single human cell contains more than 6 feet of tightly packed DNA. Multiply that by the roughly 30 trillion cells in the average human body, and the total length becomes almost impossible to fathom.

What makes this even more mind-boggling is how efficiently it all fits in the body. That 6-foot strand of DNA inside each cell is folded, looped, and coiled into a microscopic nucleus just a few micrometers wide. Proteins called histones act like spools, wrapping and organizing DNA so an enormous amount of genetic information can be stored in an incredibly small space.

DNA could one day store the world’s data.

Scientists are exploring ways to use DNA as a form of data storage — essentially turning it into a biological hard drive. Instead of storing information as 1s and 0s (as a computer does), DNA stores information using four chemical “letters”: A, T, C, and G. By translating digital data into those letters, researchers can encode text, images, and even video into synthetic DNA strands.

The appeal is density and durability. A single gram of DNA could theoretically hold hundreds of billions of gigabytes of data, far more than today’s storage devices are capable of. And unlike hard drives, which wear out over time, DNA can remain stable for thousands of years if kept in the right conditions. It’s still expensive and slow compared to modern storage, but the same molecule that stores the instructions for life could one day archive all of the information online.

The human body is an amazing powerhouse fueled by important organs like the heart, lungs, and brain. However, some of its most vital work is done by a body part you might not expect — our taste buds, a set of microscopic organs that do more than help us savor our food. Scientists believe human taste buds also have a bigger purpose: protecting us from poisoning. These microscopic sensors tell our brains that food is safe to eat based on flavor, encouraging us to consume sweets (potential sources of calories and energy) and alerting us to spit out bitter or unpalatable substances that could make us sick. 

You might like (or dislike) foods based on your genes.

Ready to reveal?

Oops, incorrect!

It's a fact

Food preferences are tied to culture and exposure, but scientists believe genetics may also play a role. Mutations in the DNA that power taste receptors can impact how taste buds perceive sweetness, bitterness, and even the flavor of coffee, cilantro, and other foods.

Taste buds are such hardworking organs that their cells die off quickly. As they work, they age and lose sensitivity, which is why the body regenerates them about every two weeks. However, taste buds aren’t all replaced at once; on any given day, about 10% of the sensors expire, while 20% to 30% are in the process of developing, leaving us with 60% of the buds active to analyze the food we consume. 

Want to examine your taste buds? Contrary to popular belief, it’s not as easy as sticking out your tongue. That’s because the visible bumps aren’t sensors themselves; instead what you see are the papillae, which cover the taste buds. Each papillae can house hundreds of taste sensors, with the average adult having between 2,000 and 10,000 — a number that generally decreases with age. However, there’s one upside to losing some taste sensitivity as we get older: Foods we once avoided in childhood, like Brussels sprouts, become a bit more palatable.

Taste buds aren’t just on your tongue.

It makes sense that taste buds are generally found in our mouths; after all, they help encourage us to eat and can sense potential poisons. However, researchers have found that taste buds don’t just exist on our tongues — they can be found all over the body in unexpected places. Taste buds can be found in our stomachs, and in 2007, researchers at Mount Sinai School of Medicine discovered sweet-sensing taste buds inside the intestines. It’s believed that those sensors monitor glucose and help the body control blood sugar. Taste buds also exist in the muscled walls of our lungs, where they work to protect breathing; upon sensing a bitter substance, the taste buds tell the body’s airway to open, a breakthrough some researchers say could be used to develop more effective asthma medications.

Physicist Amos E. Dolbear is known for his work on early telephones and other inventions, but an 1897 issue of The American Naturalist contained a different type of scientific contribution: the hypothesis that cricket chirps are linked to air temperature. Dolbear’s observations (likely of snowy tree crickets, or Oecanthus fultoni) led him to theorize that the frequency of their chirps increased with warmer weather, and slowed as the thermometer fell. Surely, the phenomenon could be used to “easily compute the temperature when the number of chirps per minute is known,” Dolbear wrote. Most entomologists now agree that his theory — called Dolbear’s Law — is pretty spot-on, thanks to how insects respond to environmental changes. As cold-blooded creatures, crickets are unable to regulate their body temperatures internally, relying on the sun’s heat to fuel their metabolisms and provide the energy they need. Warmer temperatures allow the six-legged critters to use more energy, allowing more of the chemical reactions in their bodies that produce muscle contractions (and thus chirps) to occur — which we hear in the form of faster-paced songs

The earliest known insects couldn’t hear.

Ready to reveal?

Oops, incorrect!

It's a fact

Some scientists believe the first prehistoric bugs were actually deaf. Some species evolved unique hearing organs over the past 400 million years — take the bladder grasshoppers’ abdomen ears or praying mantis’ lone chest ear — but others, like ants and beetles, remain unhearing.

You can easily test Dolbear’s Law on the next warm, buzzing night. Tune in to one cricket’s song, count the number of chirps you hear in 15 seconds, and add 37 for an approximate forecast in degrees Fahrenheit. (If math isn’t your strong suit, the U.S. National Weather Service has a handy cricket chirp converter that also provides a Celsius conversion). There are some limitations to using a cricket temperature gauge, however: Most crickets won’t sing when temps dip below 55 degrees or when heat pushes the thermometer past 100. And while many crickets respond to temperature shifts this way, not all chirp at the same rate. Fortunately, the snowy tree cricket is widespread throughout the United States — where, perhaps unsurprisingly, it’s also known as the thermometer cricket.

Some crickets can’t chirp.

Another snag when forecasting á la insect: Depending on where you live, local crickets may chirp less frequently or not at all, due to evolutionary changes that keep them out of harm’s way. Thanks to their low placement on the food chain, crickets rely on tricks such as camouflage and lofty leaps to escape predators, but some species have also modified or muted their defining feature — chirps — as a survival technique. Jerusalem crickets hiss instead of chirping, while camel crickets lack the anatomy to make any sound at all. Oceanic field crickets found in Hawaii have quickly evolved over the past 20 years to stop chirping altogether, a new trick designed to evade parasitic flies attracted by their songs. And while the flying sword-tailed cricket of Panama does chirp, the species has learned to embrace silence, too — the crickets can hear ultrasonic bat calls, giving them enough warning to silently drop from mid-air flight to avoid capture.

Bubble Wrap is one of the 20th century’s most versatile — and dare we say most beloved — inventions. The pliable, air-pocketed sheets have been used for decades to insulate pipes, protect fragile items, and even make dresses. And that’s not to mention the fascination some people have with popping its bubbles (both competitively and for fun). But when it was first created in 1957 in New Jersey, inventors Al Fielding and Marc Chavannes had a different vision in mind for their ingenious padding: home decor. The pioneering duo hoped their creation — which trapped air between two shower curtains run through a heat-sealing machine — would serve as a textured wallpaper marketed to a younger generation with “modern” taste. The initial idea was a flop, however, and Fielding and Chavannes soon pivoted to promoting Bubble Wrap, then called Air Cap, as a greenhouse insulator (another idea whose bubble would quickly burst). 

Wallpaper was once used to keep homes pest-free.

Flock wallpapers, known for their velvety feel and elaborate designs, were first crafted in the 17th century using leftovers from the wool industry. The thick, fuzzy panels were in part popular because installation required turpentine, the scent of which repelled moths.

It took another invention of the time — IBM’s 1401 model computer — to seal Bubble Wrap’s fate as a packing material. Under the company name Sealed Air, Fielding and Chavannes approached IBM about using the air-filled plastic in shipping containers, replacing traditional box-fillers like newspaper, straw, and horsehair. After passing the test of transporting delicate electronics, Sealed Air became a shipping industry standard. Over time, Fielding and Chavannes were granted six patents related to Bubble Wrap manufacturing, and Sealed Air continues to create new versions of the remarkable wrap — including a cheaper, unpoppable version that’s popular with cost-minded shippers (but not so much with bubble-popping enthusiasts).

Bubble Wrap was nominated to the Toy Hall of Fame.

Some of the best toys aren’t toys at all — a phenomenon well known to people who spend painstaking hours selecting gifts for kids, only for the items to sit ignored in favor of the toy’s packaging. That allure among the younger set helped secure Bubble Wrap a nomination to the National Toy Hall of Fame in 2016 as a nontraditional toy (akin to honorees such as the stick and the cardboard box). The poppable plastic didn’t become an official inductee, but its appeal has been replicated by the Pop It!, a squishable popping toy with a feverish following. The silicone poppers provide endless snaps that some psychologists say can reduce tension and anxiety. While the fidget toy seems like a modern solution to everyday jitters, Pop-Its were actually invented in 1975 by a former classmate of Anne Frank. Five decades later, reduced manufacturing costs have given the bubble-bursting toy a second chance at soothing anxious minds of all ages.
