WTF Fun Fact 13149 – Spiders Recycle Their Webs

Not all spider webs are destroyed with a broom. In fact, spiders can recycle their webs by eating them!

How and why do spiders recycle their webs?

Some spider webs are built to last years while others only last a day or so. Of course, while those beautifully spun webs in the corner of your attic may have been built as a long-term home for the spider, in that case, their duration is influenced by how long humans allow them to stick around.

But for some neglected spider webs, they can be so enduring that a new generation of spiders might come to reside there.

More fragile webs may only last a day because spiders build them simply to catch food. Rain and pollen may affect their stickiness. In these cases, spiders will pack up a web for the day and build again the next. When this happens, spiders often eat their webs to recycle the amino acids that made up the silk protein used in web construction.

It’s an impressive feat since webs can consist of 65 feet of silk!

Not all spiders ingest their silk though. And some use it to wrap their eggs sacs. But considering how much energy it takes to weave a web, it’s not all that surprising that spiders recycle webs by eating them in some cases.

Spider web building

Spider web silk is made out of protein chains. And some of it is as strong as kevlar (though obviously it’s not as tightly woven, so we hardly notice when batting them away). In fact, scientists are studying it in the hopes of making future body armor!

Spiders typically start building webs by pulling silk from a gland in their fourth leg. The fourth leg on the opposite side contains even more silk glands. Then, in order to begin, the spider (depending on the species) can shoot it out to attach to an object or wait for a breeze to carry it to the base from which it will start building.

From there, the spider will typically create a number of attachment lines. Then they decide which are the strongest and begin weaving from there. Different spiders have different web patterns. In fact, they’re so distinct that experts can look at the structure of a web and tell you precisely which type of spider built it.

WTF Fun Fact 13148 – Pentheraphobia

Pentheraphobia means the fear of your mother-in-law. And while fear might not be the word most people would use, a phobia also refers to anxiety produced by the trigger and subsequent avoidance (to which more of us may be able to relate).

Is pentheraphobia real?

A phobia typically refers to an unfounded fear or dislike – and, let’s face it, some mothers-in-law are scary and threatening. (Of course, some are delightful!).

But the fear of one’s mother-in-law can be real for people who suffer from anxiety and who let their in-laws’ behavior or presence affect their lives in negative ways.

Pentheraphobia is not widespread (or widely recognized). While this specific phobia is not in the Diagnostic and Statistical Manual of Mental Disorders (DSM), general phobias are. And to qualify as a psychiatric disorder, a phobia must produce excessive and persistent fear, induce a state of panic around the trigger, and lead to unhealthy coping mechanisms in order to avoid contact.

According to Its Psychology (cited below): “It is a specific phobia, and it is important to clarify that it differs from a simple dislike or hatred because it can seriously affect the sufferer of the disorder.”

Fear of in-laws

If you’re not a fan of your in-laws or other parental figures, Its Psychology has a few other potential diagnoses to bring up with your doctor:

  • Socerafobia (fear of in-laws in general)
  • Vitricofobia (fear of the stepfather)
  • Novercaphobia (fear of the stepmother)

Suffering from phobias

While fear of one’s mother-in-law may seem amusing in some respects, the symptoms of phobias are no joke. They can include nausea, vomiting, tremors, irregular heartbeat, excessive sweating, and panic attacks. It goes far beyond dread.

Many phobias are believed to be rooted in past psychological trauma. Of course, you don’t have a mother-in-law until later in life, but it’s possible that you can be conditioned from a young age to fear non-blood relatives or pick up on other people’s fear or animosity towards their mothers-in-law. — WTF fun facts

WTF Fun Fact 13147 – Lay-Z-Boy Tank Seats

During World War II, Lay-Z-Boy had to stop producing recliners because of the war effort. As a result, they used their production facility to mass produce (presumably very comfortable) seats for tanks and other military vehicles.

The history of Lay-Z-Boy

Lay-Z-Boy is pretty much synonymous with recliners. The Monroe, Michigan company produces about 30,000 units per week!

The company was founded in 1927 by cousins Edwin Shoemaker and Edward Knabusch, a cardboard factory worker and a farmer, respectively. They were both interested in woodworking and began designing furniture.

Eventually, they built a reclining porch chair out of crates. But realizing that it wasn’t going to be very useful in the snowy Michigan winter, they followed up on a suggestion from a local furniture store owner to upholster it so it could be used inside.

Their “Automatic Adjustable Chair” wasn’t much of a marketing hit, so they held a contest to rename it. According to AdWeek (cited below), “suggestions included the Slack Back and the Sit-N-Snooze,) but “the founders settled on La-Z-Boy.”

An interruption in sales

It would take decades for the brand to become a household name. And the real secret to its success was the popularity of home televisions in the 1960s.

Unfortunately, the 1940s were a tough time for the company. After hardly being able to keep up with demand, Lay-Z-Boy built its first stand-alone 27,000-square-foot factory. However, production was interrupted one year later because of WWII.

As a result of the war, the company stopped lounge chair production and used its factory to mass produce plane parts as well as seats for war machines like ships, tanks, torpedo boats, and armored cars.

We’re guessing they didn’t recline.

Luckily, the pent-up demand during the way meant the Lay-Z-Boy was back in business in the 1950s. They installed an assembly line to help meet demand and invented the reclining rocker.

The 1960s were the real golden era for Lay-Z-boy. AdWeek notes that “Between 1961 and 1970, sales went from $2M to $50M.” Today, the chairs’ prices make them a near-luxury item. — WTF fun facts

WTF Fun Fact 13146 – Oldest Library in the World

Al-Qarawiyyin Library is the oldest library in the world. It is located in Fez, Morocco, and was part of the oldest continually operating university in the world, al-Qarawiyyin University. The university opened in 859. (If you’re thinking this can’t be right because Oxford is the oldest university, note that it’s simply the oldest in the English-speaking world. Even the University of Bologna was founded after al-Qarawiyyin.)

Al-Qarawiyyin had a library, but sultan Abu Inan Faris founded the one we consider the oldest continually operating library in 1349. He was able to collect some of the world’s most precious manuscripts.

How the al-Quarawiyyin Library came to be

Al-Qarawiyyin university, its library, and a mosque were founded by a woman (around the same time algebra was invented!).

Her name was Fatima El-Fihriya, and she even attended the university. Born in Tunisia around 800 AD, her family became wealthy as a result of her father’s successful merchant business and migrated to Fez.

Both well-educated, Fatima and her sister Maryam went on to found mosques in Fez. Fatima’s wealth was a result of her father having only two daughters to leave his riches to, and Fatima’s husband and father died shortly after her wedding. However, we know little else about their lives. A fire in 1323 destroyed most of the records that could tell us more about her life.

It appears Fatima El-Fihriya’s goal was to make Morocco an educational hub, which she did. In fact (while it’s disputed), she likely influenced the future of educational institutions around the world.

Al-Qarawiyyin offered many courses on the Qur’an, but eventually expanded to include the study of medicine, grammar, mathematics, music, and astronomy. It drew intellectuals from all over the world.

Once accessible only to academics, the library is now open to the public thanks to a full renovation Canadian-Moroccan architect Aziza Chaouni began in 2012 and finished in 2017.

WTF Fun Fact 13145 – World Website Statistics

While more people use the internet in Asia than anywhere else in the world, English is the predominant language of the world’s websites. According to First Site Guide (cited below): “25.9% of the internet is in English, 19.4% is in Chinese, and 8% is in Spanish.” Keep reading for more worldwide website statistics.

More world websites statistics

Asia has over 2.8 billion web users, with over 1 billion active users residing in China and 659 million in India.

Europe is the continent with the second most internet users, though they have under 700 million. The US comes in third with 307 million users (as of early 2022).

The age group with the most internet users (at least as of 2019) is 25 to 34-year-olds. They account for 1/3 of web users.

The majority of people also use Chrome as their browser. In fact, 65% of people use Chrome while the next most popular engine (Safari) is used by 16.82% of users.

According to First Site Guide: “The most connected region globally is North America, with over 75% of people having an internet connection. It is closely followed by Europe, in which over 68% of all people have internet access. The region with the least internet connectivity is Sub-Saharan Africa, with 24% of people having internet access according to internet usage statistics.”

Worldwide web searches

Google is by far the most popular search engine, holding 92.7% of the market share. In second place is Bing with just under 3%.

While DuckDuckGo is the search engine with the most privacy features, it’s used by only .5% of internet users.

And while you might think iPhones are ubiquitous, they’re also expensive. That’s probably why most mobile internet users (nearly 75%) use an Android OS.

And time spent on smartphones is rapidly increasing. 12 years ago, we spent less than an hour a day looking at the internet on our mobile devices. Today, we average about 2.8 hours. And this is only expected to increase. — WTF fun facts

WTF Fun Fact 13144 – The Number of Internet Users

In November of 2022, the world population reached an estimated 8 billion people. The number of internet users is around 5.47 billion. That’s a lot, but it still leaves a mind-boggling number unconnected (for better or worse).

More internet user stats

The 5.47 billion number refers to active internet users, so it doesn’t imply that everyone else lacks Internet connectivity altogether. However, it’s estimated that 2.7 billion people do lack access to the internet.

First Site Guide (cited below) also gathered some other eye-popping internet facts from 2022. For example, did you know that 4.32 billion people use mobile devices to access the internet? And as we walk around, we’re surrounded by an average of 26 “smart” objects connected to the internet.

When it comes to social media, the majority of internet users are on some form of it. In 2021, there were 4.2. billion active social media users. (It remains to be seen if controversies associated with Twitter and Facebook will reduce that number or send people to other sites.)

We were surprised to know that 7 million blog posts get published every day, though it’s not clear exactly what counts as a blog and if some news items (or posts that people treat as news) get counted in this. What we do know is that there are around 198.4 billion websites, so people have plenty to choose from.

Who has the highest number of internet useres

Denmark, Iceland, the UAE, Kuwait, and Qatar have the highest “internet penetration” rates in the world. In fact, over 98% of the people in these countries have internet access (and the average internet speed in the UAE is a whopping 110.90 Mbps!). However, China has the most number of internet users.

North Korea, unsurprisingly, has the least number of internet users. — WTF fun facts

WTF Fun Fact 13143 – Grass Screams When Cut

You’ll never cut your grass again without thinking of this weird fact – grass cries for help when it’s mowed. No, you can’t hear it, but scientists have discovered grass screams when cut.

How does grass scream when cut?

We’re only just beginning to understand how plants communicate with one another and the rest of the world around them (including insects).

Dr. Michael Kolomiets, a Texas A&M AgriLife Research plant pathologist, published an article in 2014 in The Plant Journal noting that the aroma of cut grass is the plant’s way of both signaling distress and attracting beneficial insects that will help it heal.

According to ScienceDaily (cited below): “When there is need for protection, the plant signals the environment via the emission of volatile organic compounds, which are recognized as a feeding queue for parasitic wasps to come to the plant that is being eaten and lay eggs in the pest insect,” Kolomiets said.

Plant communication

Grass produces a “defensive” protein when damaged. Of course, that doesn’t stop the lawnmower or insects from destroying the blades. But it appears to produce a compound that repels insects that are feeding on the damaged grass.

This compound, or one related to it, also appears to attract organisms like parasitic wasps that feed on insects like caterpillars that are destroying the grass.

Or to put it in science-speak:

“We have proven that when you delete these volatiles, parasitic wasps are no longer attracted to that plant,even when an insect chews on the leaf. So this volatile is required to attract parasitoids. We have provided genetic evidence that green leafy volatiles have this dual function — in the plant they activate production of insecticidal compounds, but also they have indirect defense capability because they send an SOS-type signal that results in attraction of parasitic wasps.”

So, maybe it’s not so much that grass screams when cut so much as it cries for help. Either way, freshly cut grass emits a compound that repels damaging insects and attracts insects with a protective function.

It’s just one of the many ways that plants are far more complex than we had ever previously imagined. — WTF fun facts

WTF Fun Fact 13142 – Use of Telemedicine in the U.S.

Telemedicine use skyrocketed during the pandemic, and now it seems poised to become a regular part of the healthcare landscape. A CDC report from October 2022 revealed just how much Americans relied on telemedicine in the previous year.

What is telemedicine?

Telemedicine is the use of electronic means (telephones, text messages, voice and video chats, etc.) to deliver healthcare to patients remotely. While it may occasionally involve in-office testing, most of the doctor-patient relationship takes place over a device like a phone or a computer.

During the COVID-19 pandemic State of Emergency, the U.S. expanded legislation to allow more providers to deliver a broader range of care options via telemedicine. Healthcare providers had been relatively limited in what they could do for patients without seeing them in person before this.

A CDC report using 2021 National Health Interview Survey (NHIS) data to assess the use of telemedicine provided interesting insight into just how many Americans over age 18 took advantage of what it had to offer in the second year of the pandemic.

The rise of telemedicine use

In 2021, 37% of American adults reported using telemedicine in the previous 12 months.

The report also found that the older people were, the more likely they were to use it. On some level, that makes sense since older people are more vulnerable to severe cases of COVID. However, it hasn’t often been the case that technology use increases with age in the past.

Women were also more likely to use telemedicine. 42% of women said they used it in 2021, compared to 31.7% of men. (However, women are more likely to see doctors than men.)

Other statistics

Adults in the U.S. West were the most likely to use telemedicine, and those in the Midwest were the least likely.

Telemedicine use increased with patients’ urbanization level – those living in large metropolitan areas were more likely to use it. This is interesting because the technology was initially used to reach those who lived far from hospitals and clinics. However, during the pandemic, people in urban areas may have been more reluctant to head to hospitals and seek care due to crowded public transportation and waiting rooms.

Those with a GED or higher education level were also more likely to get on the phone or computer to “visit” their doctor. As education levels go up, so does the use of this technology.

And while those with a below-average or average income are equally likely to engage with healthcare providers electronically, its use increases among those with higher incomes.

It appears that if telemedicine is going to be part of the future of medicine, it will be important to ensure a broader range of people have access to it and knowledge about its benefits. — WTF fun facts

WTF Fun Fact 13141 – Making Champagne Secular

As you likely know, champagne production for the masses started with a Benedictine monk named Dom Perignon. And while it might seem odd that we have a French Abbey to thank for our New Year’s bubbles (after all, he made it so they could be mass-produced and shipped worldwide), it actually took time for the drink to lose its religion and to make champagne secular.

How champagne became secular

Fr. Dom wasn’t the reason champagne was associated with religion, to begin with. In fact, he’s one of the reasons it became a worldwide phenomenon.

You see, bubbly was not only difficult but dangerous to produce because bottles would explode. For a long time, sparkling wine was confined within the walls of the institution that made it. That is until the French kings got involved. Eventually, it became a celebratory drink for things like baptisms and coronations.

As VinePair (cited below) puts it:

“Before the abolition of the French monarchy, France’s royal family had longstanding ties to the Champagne region. The multi-century connection began in 496, when reigning monarch Clovis I was baptized in a small church in Reims. The city and that exact spot (which was eventually replaced by a grand cathedral) went on to become the traditional location for French coronations, and cemented the link between region and royalty.”

In other words, wine from Champagne (pre-bubbles) started out as a holy wine.

Of course, red Burgundian wine was long the official celebratory wine of France. But when secondary fermentation was discovered by Dom Perignon in 1668, things changed…slowly.

Rise of the champagne industry

In the 18th century, King Louis XV became a champagne lover, making it very fashionable. It was also chic because he made sure it was the only wine that could be sold in glass bottles (which also made it dangerous because of all the exploding glass, but that’s not really a matter for kings to care about).

Eventually, if you wanted to be cool in France, you had to buy wine from Champagne.

At this point, champagne had made it out of the Abbey walls and into castles. However, this is all pre-French Revolution, in a time when kings and Catholics ruled.

Then came the Revolution. Heads came off, heads of state were replaced, and people became far more skeptical of powerful institutions, including the church.

There’s no one moment (that we know of) when champagne became untangled from production by religious workers, but the Revolution certainly changed the nature of all things elite.

Marketing secular champagne

By 1796, George Washington was serving champagne at a state dinner.

And, according to VinePair, “Within a century, one didn’t even have to hold office to toast with Champagne. In the latter half of the 1800s, increasing supply and better worldwide distribution channels made Champagne a commodity most middle-class families could afford…The period also saw significant marketing efforts from Champagne houses to place their bubbles as the celebratory beverage. The images and language on many bottle labels targeted newly engaged couples and soon-to-be parents…”

It was no longer associated with religion, but with any kind of celebration. — WTF fun facts
