Berry classification is a confusing business. People began referring to some fruits as “berries” thousands of years before scientists established their own definitions, some of which are still debated. Today, little effort is made to teach the public about what botanically constitutes a berry, so here’s a bit of help. It’s generally accepted that all berries meet three standards. First, they have a trio of distinct fleshy layers (the outer exocarp, middle mesocarp, and innermost endocarp); second, their endocarps house multiple seeds; third, berries are simple fruits, meaning they develop from flowers with a single ovary.  

The Beatles invented the namesake location for their song "Strawberry Fields Forever."

Located in Liverpool, England, Strawberry Field is a Salvation Army-owned property that once housed an orphanage. A young neighbor, John Lennon, used to climb over the courtyard's red gates to play with the resident children. In 2019, Strawberry Field opened to the public.

Blueberries and cranberries are true berries, as their names imply. Other berries may surprise you: Avocados, eggplants, grapes, guava, kiwis, papayas, peppers, pomegranates, and tomatoes are all, botanically speaking, berries. Bananas are berries, too, since they meet all three requirements. The exocarp of a banana is its peel, while the mesocarp is the creamy middle surrounding the seedy, also-edible endocarp. Now let’s parse what can constitute a non-berry (definitions sometimes differ). Apricots, cherries, dates, nectarines, peaches, and plums are drupes — simple fruits that have a hard endocarp comprising one seed (or, as we laypersons call it, a pit). Apples, pears, and quince are pomes, simple fruits that receive their own category owing to their core of small seeds and tough skin. With seeds growing on the outside, blackberries, raspberries, and strawberries are, confusingly given their names, neither berries nor simple fruits. Instead, they are called aggregate fruits, because they grow from multiple ovaries of the same flower. No matter what you call them, fruits are still delicious enough to be nicknamed “nature's candy.”

There’s an “Edible Park” in Asheville, North Carolina.

Named for the esteemed botanist and inventor, the Dr. George Washington Carver Edible Park debuted in 1997. Also known as the East End neighborhood’s food forest, the park supports more than 40 kinds of fruit and nut trees, including apple, grape, fig, jujube, peach, pear, plum, and paw paw (the largest edible fruit tree native to North America). Visitors are encouraged to pick whatever they like, and can also enjoy a vegetable garden, butterfly garden, and boardwalk. Much of the park maintenance is handled by volunteers from a nonprofit called Bountiful Cities, who advise guests to remember the neediest populations and not take more than they need. The park was the site of the United States’ first public food forest — and the start of a growing (pun intended) trend. Nationwide, in cities such as Atlanta and Philadelphia, more than 70 food forests aim to combat food insecurity while teaching people how to live sustainably.

We tend to think of space as cold and dark, but that’s only because most stars are light-years away from the pale blue dot we call home. The universe is actually quite bright on the whole, and its color has been given an appropriately celestial name: “cosmic latte.” In 2002, astronomers at Johns Hopkins University determined the shade after studying the light emitted by 200,000 different galaxies. They held a contest to give the result — a kind of creamy beige — its evocative moniker. (Other entries in the contest included “univeige” and “skyvory.”)

The universe is still expanding.

Ready to reveal?

Oops, incorrect!

It's a fact

Astronomers know that the universe continues to expand, though they disagree on how rapidly that’s occurring. One recent study says that it’s growing at a rate of 73.3 kilometers per second per megaparsec, with a megaparsec being about 3.3 million light-years — so, pretty fast.

As with just about everything in the universe, however, the color isn’t fixed: It’s become less blue and more red over the last 10 billion years, likely as a result of redder stars becoming more prevalent. In another 10 billion years, we may even need to rename the color entirely.

NASA didn’t really spend millions of dollars developing a pen that could write in space.

The second half of this oft-cited myth contrasts NASA’s supposed approach with that of the Soviet Union, who are said to have simply given their cosmonauts pencils. American astronauts did likewise, though NASA wasn’t always thrilled about it — pencils are flammable, and their tips breaking off could lead to damage on sensitive equipment. The so-called space pens actually came from the Fisher Pen Company, which offered its AG-7 “Anti-Gravity” pen to NASA in 1965. None of the investment money came from the government, however, and astronauts and cosmonauts alike ended up using the writing tools at a cost of $2.39 per pen.

On a statistical level, some of the world’s most fearsome predators aren’t actually that fearsome. Wolves succeed in about only 20% of their attempts to catch prey, whereas lions enjoy a success rate of around 30% when working as a pack. Those numbers, though respectable, pale in comparison to the success rate of the mighty dragonfly, which catches about 95% of the prey it pursues — making it the world’s most successful hunter.

These insects do all their hunting in midair, of course, making the feat even more impressive; they mainly prey on small insects such as mosquitoes, flies, or butterflies. Scientists attribute this prowess to dragonflies’ nearly 360-degree field of vision, their individually controlled wings, and their brains’ unique ability to coordinate these instantaneous actions.

Most dragonflies are aquatic for the majority of their lifespan.

Ready to reveal?

Oops, incorrect!

It's a fact

Baby dragonflies reside in water before reaching their adult form, and their larval stage can last between one and three years. As adults, they typically live just six to eight weeks.

Other surprisingly adept hunters include the harbor porpoise, whose success rate hovers at around 90% (allowing them to chow down on more than 500 small fish per hour), and African wild dogs, which capture their prey more than 60% of the time — though they often lose them to larger predators such as lions and hyenas.

One dragonfly species’ migration has been called “the most extraordinary journey in nature.”

The more you learn about dragonflies, the more astonished you’ll be by these tiny creatures. Consider the globe skimmer, for instance, which more than lives up to its name: The “winged wanderer,” as it’s often referred to, completes the longest migration of any insect, an 11,000-mile journey between India and Africa that Discover Magazine called “the most extraordinary journey in nature” — in part because it takes several generations to complete, meaning no single dragonfly can complete it itself.

At just a few centimeters long, globe skimmers can fly for 90 hours straight — albeit with a fair bit of assistance from wind, which is why the journey can only be undertaken at certain times of year. To keep their energy up, they eat small insects and aerial plankton. Their exact route has yet to be plotted, however, because globe skimmers are literally too small for any existing tracking devices.

H.O.M.E.S.: Huron, Ontario, Michigan, Erie, and Superior. That’s the order in which American schoolchildren learn to recall the Great Lakes. But if you were to remember the sea-sized lakes according to their size, Lake Superior would come first. At 31,700 square miles — the approximate size of the state of South Carolina — Lake Superior is the largest of the Great Lakes. It also happens to be the world’s largest freshwater lake by surface area, holding more than 10% of the planet’s surface fresh water. (Close to 70% of Earth’s remaining fresh water is inaccessible, stored frozen in glaciers, ice caps, and permafrost.)  

There’s a national park inside Lake Superior.

Ready to reveal?

Oops, incorrect!

It's a fact

At 207 square miles, Isle Royale is the largest island in Lake Superior; it’s also one of the least-visited national parks. Visitors can only reach the park by boat or seaplane between April and October, before it closes each winter due to extreme weather conditions.

While each of the Great Lakes is massive, Lake Superior’s size is staggering. Reaching a maximum depth of 406 meters (about 1,332 feet), Superior is the coldest and deepest of its sister lakes. It contains about 3 quadrillion gallons of water — half of the water in all the Great Lakes. And while water from Lake Superior feeds into Lake Huron, scientists believe that Superior retains water so well that it would take 191 years to empty if it never received another drop.

The world’s largest freshwater island is inside Lake Huron.

Humans have long explored the Great Lakes’ rugged waters, coming across thousands of islands along the way — about 30,000, to be exact. While many of these islands are as tiny as boulders, some are exceptional in size, such as Manitoulin Island, the world’s largest freshwater island. Situated within the waters of Lake Huron, Manitoulin Island measures 100 miles in length and is large enough that it contains 108 lakes. Some of those basins are sizable enough to contain their own islands, like Lake Mindemoya, which is home to the 87-acre Treasure Island, aka the world’s largest natural island in a lake on an island in a lake. Unlike many of the Great Lakes’ smaller islets, Manitoulin Island isn’t uninhabited; because of its close proximity to Ontario, the Canadian island has a year-round population of more than 14,300 people, and is a popular spot among vacationers and tourists.

If you look closely in the mirror at the inside corner of either of your eyes, you’ll notice a pinkish protuberance. This thin, curved membrane sits directly adjacent to the eyeball and is called the plica semilunaris, which is an evolutionary remnant of the nictitating membrane, known colloquially as the “third eyelid.” (This is not to be confused with the lacrimal caruncle, a tiny bump at the very edge of the eye that helps keep the eye moist.) Though the third eyelid is useless for us modern humans, it once served a purpose for our prehistoric ancestors.

Many animals, including dogs, cats, and some birds, reptiles, and fish, still have a functioning nictitating membrane. This translucent membrane protects the eye while still allowing the animal to see, and also essentially acts like windshield wipers by removing debris and maintaining moisture. Birds rely on their nictitating membrane while in flight and fish while swimming. Its purpose in prehistoric humans remains unclear due to the lack of definitive fossil records.

Human embryos form tails during development.

Ready to reveal?

Oops, incorrect!

It's a fact

During development, human embryos briefly grow tails. This posterior appendage forms around the fifth gestational week and is usually absorbed into the body eight weeks after conception. In rare cases — fewer than 40 recorded instances to date — humans have been born with these tails.

In fact, the third eyelid is believed to have lost its usefulness in humans long before the first appearance of Homo sapiens roughly 300,000 years ago. This is due to relaxed selection — an evolutionary phenomenon wherein formerly advantageous traits become less prominent with infrequent use. However, these traits can continue to physically stick around if they don’t actively hinder survival. The plica semilunaris is an example of one of these vestigial structures — a useless, harmless feature that shrunk but never fully disappeared.

Charles Darwin waited more than two decades to publish his theory of evolution.

From 1831 to 1836, naturalist Charles Darwin traveled the world researching evolution — but even after his return to England, he didn’t reveal his findings to the public for another two decades. Some claim Darwin feared a negative reaction from scientific and religious communities, while others suggest he used the gap to ensure his theory was irrefutable, hoping to compose an extensive, unassailable treatise before informing the world.

In 1858, Darwin received an essay from naturalist Alfred Russel Wallace that proposed similar evolutionary theories to his own. This unexpected development prompted Darwin to divulge his findings to the scientific community alongside Wallace. In 1859, he introduced his theory of natural selection in his work On the Origin of Species. Later, in 1871, Darwin published The Descent of Man, and Selection in Relation to Sex, in which he first publicly posited that humans descended from apes.

Every fingerprint is unique, but that doesn’t mean they’re easy to tell apart — especially since humans aren’t the only species that’s developed them. Chimpanzees and gorillas have fingerprints too, but it’s actually koalas — far more distant on the evolutionary tree from humans — whose prints are most similar to our own. This was first discovered by researchers at the University of Adelaide in Australia in 1996, one of whom went so far as to joke that “although it’s extremely unlikely that koala prints would be found at the scene of a crime, police should at least be aware of the possibility.” 

Koalas are bears.

Ready to reveal?

Oops, incorrect!

Koalas are actually marsupials, which makes them more closely related to opossums and kangaroos than to grizzlies or pandas. A defining trait of marsupials is that they carry their young in a pouch called a marsupium — which is where they get their name.

That discovery lent support to one of the primary theories in the centuries-long debate over the purpose of fingerprints and their swirly microscopic grooves: They help grasp. Koalas’ survival depends on their ability to climb small branches of eucalyptus trees and grab their leaves to eat, so the fact that they developed fingerprints — which assist in that action — independently of primates millions of years ago is likely no coincidence.

Before fingerprints, body measurements were used to identify criminals.

In 1879, several decades before the use of fingerprints became widespread, a French criminologist named Alphonse Bertillon developed a system based on body dimensions to identify and catalogue criminals and suspects. The five main measurements were head length, head width, length of the middle finger, length of the left foot, and length from the elbow to the end of the middle finger. Each of these was classified as being either small, medium, or large. Despite his insistence that “every measurement slowly reveals the workings of the criminal,” the system was imprecise, and eventually law enforcement agencies turned to fingerprinting instead.

Today carrots are practically synonymous with the color orange, but their auburn hue is a relatively recent development. When the carrot was first cultivated 5,000 years ago in Central Asia, it was often a bright purple. Soon, two different groups emerged: Asiatic carrots and Western carrots. Eventually, yellow carrots in this Western group (which may have developed as mutants of the purple variety) developed into their recognizable orange color around the 16th century, helped along by the master agricultural traders of the time — the Dutch. 

Eating too many carrots can turn your skin orange.

Ready to reveal?

Oops, incorrect!

It's a fact

Carrots contain a red-orange pigment called beta-carotene. Carotenemia occurs when eating too many beta-carotene-rich foods turns human skin a yellowish orange. If you were to eat 10 carrots a day for weeks, you could develop it — but doctors don’t recommend trying it.

A common myth says the Dutch grew these carrots to honor William of Orange, the founding father of the Dutch Republic, but there’s no evidence of this. What’s more likely is that the Dutch took to the vegetable because it thrived in the country’s mild, wet climate. (Although the orange color may have first appeared naturally, Dutch farmers made it the predominant hue by selectively growing orange roots — scholars say these carrots likely performed more reliably, tasted better, and were less likely to stain than the purple versions.) The modern orange carrot evolved from this period of Dutch cultivation, and soon spread throughout Europe before making its way to the New World. Today, there are more than 40 varieties of carrots of various shapes, sizes, and colors — including several hues of purple

Purple is associated with royalty thanks to a rare mollusk.

For most of European history, creating a rich, resilient purple dye was an extremely expensive process. The dye could only be made from the dried mucus glands of murex shellfish found near the ancient Phoenician town of Tyre on the Mediterranean (now part of Lebanon). Making just 1 gram of this pigment, known as Tyrian purple, required nearly 9,000 of these mollusks, so only the very wealthy — emperors and royals — could afford to use the color. In ancient Rome, purple became associated with the power of the emperor, and the idea continued after the empire’s fall. In medieval and Elizabethan England, a series of sumptuary laws ensured that the color purple was reserved only for the most elite members of society “upon payne to forfett the seid apparel.” Luckily, in 1856, chemist William Henry Perkin accidentally created a synthetic purple dye, later called mauve, while trying to synthesize a drug for malaria. Purple’s imperial reign was over.

Animal-based names are surprisingly common when it comes to units of measurement. In addition to horsepower (which usually measures the output of engines or motors) and hogsheads (today mostly used for alcohol), there’s also the mickey — a semi-official means of measuring the speed of a computer mouse. Named after a certain Disney character who’s probably the world’s most famous rodent, it’s specifically used to describe the smallest measurable movement the device can take. In real terms, that equals 1/200 of an inch, or 0.1 millimeter. Both the sensitivity (mickeys per inch) and speed (mickeys per second) of a computer mouse are measured this way by computer scientists.

Mickey Mouse wasn’t the character’s original name.

Ready to reveal?

Oops, incorrect!

It's a fact

The character was originally called Mortimer Mouse, which was changed at the behest of Lillian Disney, wife of Walt Disney. That name was reused for Mickey’s longtime rival, who first appeared in 1936.

Had the original name for the device stuck, it’s unlikely this measurement system would have come about. The mouse was briefly known as a “bug” when it was invented at the Stanford Research Institute to make computers more user-friendly, though that seems to have been a working title that no one was especially fond of. (That version of the device was also extremely primitive compared to the mice of today — it even had a wooden shell.) As for how the mouse got its current name, no one can quite remember, except that that’s what it looked like.

A lot of people didn’t think the mouse would take off.

In perhaps one of the most infamous articles ever published about computers, the San Francisco Examiner’s John C. Dvorak wrote in 1984, “The Macintosh uses an experimental pointing device called a ‘mouse.’ There is no evidence that people want to use these things.” Written as a review of Apple’s landmark personal computer, which had launched earlier that year, Dvorak’s not-so-prescient article wasn’t exactly a hot take at the time. The relatively small number of people who used computers regularly back then were just fine using the keyboard for everything, and Dvorak was hardly alone in asserting that he didn’t want to use a mouse. His predictive abilities didn’t seem to improve with time, alas, as he also wrote that Apple should “pull the plug” on the iPhone prior to its 2007 release.

Radium is, quite famously, not good for you. Its effects on the body are deleterious, not that anyone realized this when Marie Curie discovered the alkaline earth metal in 1898 — a scientific breakthrough that led to her winning the 1911 Nobel Prize in chemistry. Before long, the dangerously false belief that radium had health benefits began to spread: It was added to everything from toothpaste and hair gel to food and drinks, with glow-in-the-dark paints made from radium still sold into the 1970s. It was marketed as being good for any “common ailment,” with radioactive water sold in small jars that shops claimed would “aid nature” and act as a natural “vitalizer.”

Radium is the heaviest alkaline earth metal.

The five other earth metals — beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), and barium (Ba) — all weigh less.

Of course, none of this was true — exposure to even a small amount of radium can eventually prove fatal. Curie had no way of knowing this at the time, just as she didn’t have the slightest inkling that her notebooks would remain radioactive for more than 1,500 years after her death. She was known to store such elements out in the open and even walk around her lab with them in her pockets, as she enjoyed how they “looked like faint, fairy lights.”

On January 9, 2007, Apple CEO Steve Jobs revealed the iPhone to the world. Since then, Apple’s pricey slab of glass stuffed with technology has become synonymous with the word “smartphone” (sorry, Android fans). But smartphones predate the iPhone by more than a decade. To pinpoint the smartphone’s true birthdate, look back to November 23, 1992, and the introduction of IBM’s Simon at a trade show in Las Vegas. Today, IBM is best known for supercomputers, IT solutions, and enterprise software, but in the ’80s and early ’90s, the company was a leader in consumer electronics — a position it hoped to solidify with Simon.

The Finnish telecommunications company Nokia was originally a paper mill.

Ready to reveal?

Oops, incorrect!

It's a fact

Nokia is a fixture of cell technology — you’ve almost certainly heard their flagship ringtone, an adaptation of Francisco Tárrega’s “Gran Vals.” But the company actually began as a paper mill in 1865. In fact, it’s only been primarily a telecommunications company for about 30 years.

Simon was a smartphone in every sense of the word. It was completely wireless and had a digital assistant, touchscreen, built-in programs (calculator, to-do list, calendar, sketch pad, and more), and third-party apps, something even the original iPhone didn’t have. The idea was so ahead of its time, there wasn't even a word for it yet — “smartphone” wasn’t coined for another three years. Instead, its full name when it debuted to the larger public in 1993 was the Simon Personal Communicator, or IBM Simon for short. But there’s a reason there isn’t a Simon in everyone’s pocket today. For one thing, the phone had only one hour of battery life. Once it died, it was just a $900 brick (technology had a long way to go before smartphones became pocket-sized; Simon was 8 inches long by 2.5 inches wide). Cell networks were still in their infancy, so reception was spotty at best, which is why the Simon came with a port for plugging into standard phone jacks. In the mid-aughts, increases in carrier capacity and the shrinking of electronic components created the perfect conditions for the smartphones most of us know today. Unfortunately for Simon, it was too late.

Nikola Tesla predicted the smartphone 66 years before IBM’s Simon.

Famed scientist Nikola Tesla — best known for developing the modern AC electrical system — was also something of a technological soothsayer, accurately describing future tech such as Wi-Fi, self-driving cars, and MRIs several decades before their creation. But in 1926, during an interview with Collier’s magazine, Tesla really channeled his inner Nostradamus when he foresaw a world in which “through television and telephony we shall see and hear one another as perfectly as though we were face to face, despite intervening distances of thousands of miles … a man will be able to carry one in his vest pocket.” Tesla arguably not only foresaw the convergence of different types of technology (i.e., television and telephones) into one device, but also predicted the eventual miniaturization of these technologies into something pocket-sized. In fact, the only thing slightly inaccurate in this prediction is Tesla’s belief that vests would still be in fashion.
