WTF Fun Fact 13206 – The Bombardier Beetle

by

You may have heard of the Bombardier beetle since they have a rather interesting ability. Or as National Geographic (cited below) puts it, “the infamous ability to synthesize and release rapid bursts of stinky, burning-hot liquid from their rear ends.”

Tell me more about the bombardier beetle!

There are actually over 500 species of bombardier beetle (and about 40 in the US alone). These creatures live in many different types of ecosystems. The boiling hot chemicals they can shoot out of their rears as a defense mechanism can reach temperatures up to 212 degrees Fahrenheit. And the beetle can shoot the spray multiple times in quick succession. The spray can also produce a loud popping noise as it is released, adding an extra deterrent.

The details are even more fascinating.

In the bombardier beetle, special cells produce hydroquinones and hydrogen peroxide which then collect in a reservoir. In order to spray, the beetle has to open a valve controlled by a muscle in order to release the chemicals into a separate “reaction chamber.” This chamber is lined with cells that catalyze the chemical reaction that makes the compounds hazardous to the beetle’s predators.

The catalases and peroxidases lining the chamber also aid in the reaction that generates enough heat to bring the mixture to the boiling point (though some of it becomes vapor). The pressure created by the gases closes the valve and expels the chemicals at high speed. Amazing, right?!

Should I be afraid of this creature?

People don’t need to be afraid of the bombardier beetle. They’re too small to hurt humans (about the size of a fingernail), and they don’t go around indiscriminately spraying. They use that function only as a defense mechanism against predators.

Bombardier beetles usually keep to wooded areas and fields and don’t roam around places with lots of humans. They typically have dark abdomens and reddish legs, antennae, and heads, in case you want to keep an eye out.

How on Earth did this beetle feature evolve?

Funny you should ask. Some creationists like to use the bombardier beetle’s two-chamber system as an example of their theory of irreducible complexity. They insist that since the beetle’s defense mechanism wouldn’t operate without two complex parts, they could not have evolved via small modifications and are therefore a product of “intelligent design.”

Most of the creationist rhetoric masquerading as science gives an incomplete or sloppy description of the beetle’s inner workings.

In fact, a step-by-step evolution of the beetle is pretty straightforward (even if it does seem weird to us). The beetle likely developed its ability to secrete chemicals as a defense mechanism that was released via the epidermis to make it distasteful to predators. While the steps in between are all hypothetical since we didn’t see the creature evolve, the development of the beetle we know now is easily broken down into tiny evolutionary steps we’ve seen in other species.

You’ve got to wonder why a creationist would assume God created this beetle specifically to shoot chemicals out its rear end. — WTF fun facts

WTF Fun Fact 13204 – Types of Cheese in the World

by

Believe it or not, there are over 1,800 types of cheese in the world. Cheese.com actually has a catalog of 1,830 cheeses you can search!

How can there be so many cheeses in the world?

There are so many types of cheese in the world because cheese-making is an ancient craft. Humans have been making cheese for thousands of years in many different cultures and regions. The process of making cheese is relatively simple. It only requires milk, cultures, rennet, and salt. But there are many variations on this basic recipe.

Different types of milk, cultures, rennet, aging, and processing methods result in a wide variety of textures and flavors.

Additionally, different regions have developed their own unique cheeses based on the availability of milk and the local culture and traditions. The use of different herbs, spices, and other ingredients also contributes to the diversity of cheese.

Additionally, the development of new technology and techniques in cheesemaking also allows cheese makers to experiment and create new types of cheese.

What are the different types of cheese?

We can make cheese from the milk of various animals, including cows, goats, sheep, and buffalo, and it comes in a wide variety of textures and flavors.

Some types of cheese, such as cheddar and gouda, can be aged for several years, which gives them a sharper flavor and a harder texture. Other types, such as feta and brie, are typically aged for a shorter period of time and have a softer texture and a milder flavor.

According to Wisconsin Cheese (cited below): “Many different types of cheese are named after or associated with the place they were first made. Parmesan cheese, for example, originates from the area around Parma, Italy. Gouda was first traded in the Dutch town of Gouda. And cheddar cheese originated in the English village of Cheddar in Somerset.”

WTF Fun Fact 13200 – A Group of Pugs is Called a Grumble

by

A group of pugs is called a grumble. Whatever you think of pugs, there’s something cute and silly about the grouping name. It’s certainly better than a “murder” of crows, right? Now those are some animals who got a raw deal.

Why a group of pugs is called a grumble

You can actually use “grumble” or “a grumbling” to refer to a group of pugs. But why?

Pugs are known for the snorting sound they make because of the shape of their nose. We suppose that sounds like a grumble.

But it’s more likely that the breed’s characteristic deep, throaty barking sounds are the grumble being referred to.

Pugs have a distinct, low-pitched bark that sounds like a growl or a grumble. Pugs are known for being very vocal and expressive.

It’s worth noting that a group of any dog breed is called a kennel, pack, or litter but different animals have different colloquial names, like a pride of lions.

How did we get pugs?

Pugs are actually an ancient breed of dogs that originate in China. They were known as “lo-sze” and were kept by the Emperors of China as lapdogs and companions.

They were also used as guard dogs and were highly valued for their loyalty and affectionate nature. Pugs were kept in the imperial palace and were considered a symbol of royalty and prestige.

Pugs were first brought to Europe in the 16th century by traders and soon became popular among the European nobility. They were particularly popular in Holland and England, where they were bred to have a shorter snout and a cocked tail.

The breed was further refined in the 18th and 19th centuries, and the modern Pug we know today was developed. Pugs were officially recognized as a breed by the American Kennel Club (AKC) in 1885.

Pugs are known for their distinctive wrinkles, short snout, and compact size, which makes them well-suited for living in small spaces. They also have friendly and playful personalities.

Pug problems

Pugs are a brachycephalic (short-nosed) breed. As a result, they’re prone to a number of health problems due to their unique facial structure.

For example, their short snout and small trachea can make it difficult for them to breathe, leading to respiratory issues or heat stroke in hot weather. In addition, they’re bulging eyes make them more likely to develop injuries, infections, and eyelid and cornea issues.

Pugs are also prone to skin fold dermatitis since the wrinkles on their faces can trap moisture and bacteria, leading to skin irritation and infection. Hip dysplasia and obesity are other risks in pugs due to their breeding.

That’s certainly something to grumble about!

However, proper care and regular vet checkups can help prevent or manage these health issues and ensure a good quality of life for a pug. — WTF fun facts

WTF Fun Fact 13199 – The Nike Waffle Iron Story

by

Do you know the Nike waffle iron story? They’re two things that seem to have nothing in common. However, the first pair of Nike sneakers were made in a waffle iron. The company patented the design as the “Nike Waffle” in 1974.

The weird Nike waffle iron story

The design for the sole of the first Nike shoe was created by a co-founder of Nike, Bill Bowerman, who was a track coach at the University of Oregon. Bowerman was always looking for ways to improve the performance of his athletes.

One day, while making waffles for breakfast, he noticed the unique pattern on the waffle iron and had an idea to create a shoe sole with a similar pattern. He experimented with pouring liquid urethane into his wife’s waffle iron and the Waffle sole was born.

Nike named the shoe the “Nike Waffle Trainer” and introduced it in 1974.

It was a revolutionary design that provided excellent traction and durability. It quickly became a favorite among athletes.

Nike makes its mark

The Nike Waffle Trainer was a success for Nike in the 1970s. It helped establish the company as a major player in the athletic shoe market.

Top runners wore the shoe and helped Nike become known as a company that produced high-performance athletic footwear.

Nike not only patented the design but used the waffle sole in many of their other shoe models in the following years. The Waffle Trainer was one of the first shoes that Nike marketed as a performance shoe.

Nike still produces shoes with waffle soles. But they’re not as common as they were in the 1970s.

The company still uses the Waffle sole design in some of the company’s retro releases of the Waffle Trainer and other models like the Nike Waffle Racer. The waffle sole is also used in some of Nike’s newer running shoes since it provides excellent traction and durability.

While the Waffle Trainer is not as prevalent as it was in the past, it remains an iconic and important shoe in the company’s history and is still popular among some sneaker enthusiasts.

The cost of a Nike Waffle shoe can vary depending on the specific model. For example, the retail price of the Waffle Racer, which is one of the most popular models of the Waffle series, is around $85. However, prices can be higher or lower depending on the colorway, edition, and other factors. Retro releases of the Waffle Trainer can be more expensive, as they are considered collectible items and can be sold at a premium price. Prices for these retro releases can be anywhere from $100 to $200 or even more, depending on the condition of the shoe and its rarity.

WTF Fun Fact 13198 – Turkey’s Library of Books Thrown Away

by

Garbage collectors in Turkey have curated their own library from books thrown away by residents. The books were destined for landfills, but around 6,000 books now sit on shelves waiting to be re-read by the public.

Reusing books thrown away

The trash collectors kept finding books and eventually found a place to put them. It’s an old brick building outside of Ankara that used to house a factory. Its long shape makes it ideal for the long bookshelves that make libraries so fun to browse.

In the beginning, the trash collectors would stash the books and lend them to friends. But as more people heard about it and the number of books grew, they searched for a more sustainable option. The local municipality, Çankaya, found money in the budget to open a library with these books.

We started to discuss the idea of creating a library from these books. And when everyone supported it, this project happened,” the mayor ofÇankaya,Alper Tasdelen, told CNN (cited below).

Turkey doesn’t have a public library system, so it’s up to each region to build, curate, and staff a library themselves.

A new collection and a public good

The library full of books thrown away has a full-time staff member. They’ve even converted a garbage truck into a mobile library/donation truck!

The public has started donating books to the library instead of throwing them away to rot in landfills. You’ll also find magazines and other types of reading materials in the library.

There are some other items found in the trash that have made their way to the library, such as furniture and even games. Some of the space acts as a social center for people in the town.

Talk about turning trash into treasure!

WTF Fun Fact 13197 – Steven Spielberg’s Jurassic Credits

by

Did you know Steven Spielberg was a college dropout? Well, in any case, he returned to his college, Cal State – Long Beach, when he was in his 50s to earn his BA degree. But the story of Steven Spielberg’s Jurassic credits is less well-known.

A director drops out of college – and comes back

Speilberg has been given some honorary degrees over the years and spoke at a commencement or two. For example, he spoke at Harvard’s 2016 graduation ceremony. It was there he revealed his own college story.

He told students and their parent’s about his own graduation, just 14 years earlier.

Spielberg began college in his teens but was then offered his dream job at Universal Studios in his sophomore year. He told his parents that if his movie career failed, he would re-enroll.

But it didn’t happen quite like that. It did, however, take him 37 years to finally graduate.

He told the audience:

“…eventually, I returned for one big reason. Most people go to college for an education, and some go for their parents, but I went for my kids. I’m the father of seven, and I kept insisting on the importance of going to college, but I hadn’t walked the walk. So, in my fifties, I re-enrolled at Cal State — Long Beach, and I earned my degree.”

Steven Spielberg’s Jurassic credits

It’s probably a lot easier to master college and its demands when you’re wealthy and have nothing to lose. But that’s not an attempt to diminish his achievement (just a nod to college students out there still grinding away)!

Another thing that helped the Hollywood director? Spielberg told that Harvard grads that he was given three credits in paleontology for making Jurassic Park.

Now, if you’ve seen Jurassic Park, you know there’s some sketchy molecular biology in there, but we’re hoping they got the paleontology right!

Regardless, Spielberg finished up his degree in film production. And we’re guessing he had a pretty high GPA by the end – at least in his major!

Here are some other words of advice he had to offer:

“And the way you create a better future is by studying the past. Jurassic Park writer Michael Crichton, who graduated from both this college and this medical school, liked to quote a favorite professor of his who said that if you didn’t know history, you didn’t know anything. You were a leaf that didn’t know it was part of a tree. So history majors: Good choice, you’re in great shape…Not in the job market, but culturally.”

Hey, we know an awful lot of history majors working in museums, journalism, marketing, politics, and law! We even know some who work as consultants on movie sets, Spielberg! — WTF fun facts

WTF Fun Fact 13196 – Francis Scott Key and F Scott Fitzgerald

by

Francis Scott Key and F Scott Fitzgerald have some interesting things in common. Fitzgerald’s full name is actually Francis Scott Key Fitzgerald. That’s because his parents named him after his distant relative who wrote the words to “The Star-Spangled Banner.”

Francis Scott Key and F Scott Fitzgerald were relatives

Francis Scott Key was an American lawyer, author, and amateur poet from Maryland. We know him best for writing the lyrics to the United States’ national anthem, “The Star-Spangled Banner.” The poem was originally titled “Defense of Fort McHenry.” Key wrote it in 1814 after he witnessed the bombardment of Fort McHenry by the British during the War of 1812.

F. Scott Fitzgerald was an American novelist, short-story writer, and playwright. He is considered one of the greatest American writers of the 20th century. We know him best for his novels “The Great Gatsby” and “Tender Is the Night.” Scholars characterize Fitzgerald’s works by their themes of wealth, youth, and disillusionment, and they helped to define the “Jazz Age” of the 1920s.

History.com notes that: “The two were only distantly related—Key was a second cousin three times removed—but Fitzgerald was known to play up the family connection. While driving past a statue of Key in an alcoholic haze in 1934, he supposedly hopped from the car and hid in the bushes, yelling to a friend, ‘Don’t let Frank see me drunk!””

Other fun facts about Fitzgerald

In addition to having a famous relative, History.com revealed that Fitzgerald was also an awful speller. That’s pretty impressive since he made his living writing before the days of the spell checker. Luckily, he lived in the days of good editors.

His book “The Great Gatsby” was also not a bestseller in his lifetime. “It performed poorly compared to his first two novels, selling just over 20,000 copies and only turning a meager profit for its publisher. Popular interest in the book didn’t spike until World War II when some 150,000 copies were shipped to U.S. servicemen overseas.” — WTF fun facts

WTF Fun Fact 13195 – Tartle

by

The Scots have some great words in their vocabulary. Take “tartle,” for example. Have you ever heard of it?

What is a “tartle”?

Tartle is a Scottish word. It refers to the feeling of hesitation or panic that one experiences when one can’t remember someone’s name. Scots also use it to describe the act of hesitating to introduce someone because you can’t remember their name.

When someone experiences tartle forgetfulness, it can be caused by a number of factors. These include age-related memory loss, lack of attention when the person was first introduced, or normal forgetting. It can also be related to a condition known as anomic aphasia. This is a type of language disorder that affects the ability to recall words, including names.

The word tartle is not widely known outside of Scotland, but it is a useful word to describe a common experience of social awkwardness. You can also use the word tartle to describe the general feeling of hesitation when you are trying to remember something (not just a name) or when you are in a situation where your memory failed.

According to The Scotsman (cited below): “What makes the word so special is that it doesn’t apply when you forget the person’s name entirely. Oh no. It exists only to encapsulate the brief awkwardness while you rummage around your brain for the answer.”

Describing social awkwardness

There are many words and phrases in the English language that describe social awkwardness, here are a few examples:

  • Inept: This word is used to describe a lack of social skills or ability.
  • Bumbling: This word is used to describe someone who is awkward, clumsy or inarticulate in social situations.
  • Tongue-tied: This phrase is used to describe the feeling of being unable to speak coherently or express oneself effectively in a social situation.

WTF Fun Fact 13194 – Goosebumps Muscle

by

Did you know you have a goosebumps muscle? We get goosebumps when tiny muscles in our skin’s hair follicles called arrector pili pull our hair upright. Goosebumps evolved when humans had enough body hair for this “hair-raising” action to keep them warm. We still get goosebumps, but they no longer serve a purpose in humans.

How do the goosebumps muscles work?

The arrector pili muscle is a small muscle located at the base of each hair follicle. When this muscle contracts, it causes the hair follicle to stand upright, resulting in the characteristic “goosebumps” or “gooseflesh” that many people experience in response to cold temperatures, emotional arousal, or certain stimuli.

The contraction of the arrector pili muscle can also cause the hair follicle to become more sensitive to the surrounding environment, which may help to protect the skin from cold temperatures or other environmental factors. This contraction is also mediated by the sympathetic nervous system, which is activated in response to certain stimuli such as cold, fear, anger, or pleasure.

Why do we get goosebumps?

Goosebumps occur as a response to a variety of stimuli. The most common trigger is a change in temperature, such as feeling cold. Goosebumps also occur in response to emotional stimuli such as fear, awe, or pleasure. This is because the contraction of the arrector pili muscle is mediated by the sympathetic nervous system. That is activated in response to these stimuli.

Another reason why we get goosebumps is an evolutionary one. When our ancestors had more hair on their bodies, the contraction of arrector pili muscles would make the hair stand up. This created a thicker layer of insulation to help them stay warm in cold temperatures. This response is still present in humans, even though most of us have less body hair.

Goosebumps can also occur when listening to music. This is because the emotional response to music can activate the sympathetic nervous system, which triggers the contraction of the arrector pili muscle.

Overall, goosebumps are a physiological response to a variety of stimuli that can be triggered by both environmental and emotional factors. —WTF fun facts
