WTF Fun Fact 12731 – Cute Aggression

by

Have you ever seen a chubby baby face or a fluffy bunny and thought about snuggling it to pieces? It’s called “cute aggression,” and it isn’t typically as violent as it sounds.

According to Forbes, “cute aggression” was first described by Yale researchers in 2015. It’s “actually pretty common and can encompass behaviors such as wanting to bite, nibble, squeeze, or smoosh the face of something extremely adorable.” In addition, “studies have long shown that people who view photos of tiny, adorable things often react with extremely aggressive language.”

Don’t worry – no one gets hurt

The good news is that no matter how many times we say “I just want to smush her cheeks” or “I want to cuddle that kitten SO HARD,” those words don’t actually translate into action. For the most part, we lay off the smushing and potentially painful cuddles. (Of course, toddlers and cats may not agree – they always act like a snuggle is about to kill them.)

Research into “cute aggression” was done by Katherine Stavropoulos, an assistant professor at the University of California, Riverside. She’s also a licensed clinical psychologist and neuroscientist. Stavropoulos looked at the brain’s electrical activity as subjects viewed images of really cute creatures. She published the findings in an article titled “‘It’s so Cute I Could Crush It!’: Understanding Neural Mechanisms of Cute Aggression,” in Frontiers in Behavioral Neuroscience.

Forbes states that “the new study backs up the hypothesis that these feelings may serve as a mechanism to prevent people from being overwhelmed (and thus incapacitated) by cute things. It’s basically what happens to your brain when you just can’t even.”

“Cute aggression” is all in your head

In other words, the electrical activity in our brains showed that we have a physiological reaction to cuteness. And it can be A LOT. In order to make sure we don’t actually smother baby animals (which were deemed to be the cutest things overall, producing the biggest neurological response), we use “violent” language to talk about snuggling things really hard.

That’s just how our brains respond to a cuteness overload.

Forbes also revealed that “Journalists have noted that this phenomenon is universal and that most languages have a word for this type of feeling – the Filipino language Tagalog, for example, has a word Gigil, which means gritting your teeth and trembling in an overwhelming situation.” In addition “Other studies have shown that cuteness aggression is felt far more acutely when people can’t physically touch the cute thing they’re seeing.”

That would help explain all the squealing when we see cute animal videos online. – WTF fun facts

WTF Fun Fact 12729 – Astronaut Life Insurance

by

We never really thought about astronaut life insurance, but we had hoped that heroic explorers wouldn’t have to worry about their families being taken care of in the event of their untimely demise.

Alas, that was not necessarily the case for Apollo 11 astronauts Neil Armstrong, Michael Collins, and Buzz Aldrin. They didn’t have life insurance that covered an accident involving a moon landing (or anything related to it).

“It was driven by the fact that, given the nature of the astronauts’ livelihood, they were not able to secure much life insurance,” said Apollo program author Howard C. Weinberger. According to Brandi Dean, spokesperson for NASA’s Johnson Space Center, NASA DID have an insurance program, but it “originally did not cover astronauts when flying—it was considered high risk and experimental.”

There may not have been an eBay marketplace back in 1969, but Neil Armstrong understood the power of celebrity and the value of an autograph. That’s why he suggested they all leave autographed materials behind for their families to sell in case they didn’t return.

Particularly valuable were items called covers, which are envelopes signed and postmarked on important dates.

According to NPR:

“About a month before Apollo 11 was set to launch, the three astronauts entered quarantine. And, during free moments in the following weeks, each of the astronauts signed hundreds of covers.

They gave them to a friend. And on important days — the day of the launch, the day the astronauts landed on the moon — their friend got them to the post office and got them postmarked, and then distributed them to the astronauts’ families.”

While the trio didn’t need to worry about a grim fate after all, the items did start showing up at auctions in the 1990s. An Apollo 11 “insurance autograph” was worth up to $30,000 at the time.  – WTF fun facts

WTF Fun Fact 12728 – Frederic Tudor’s International Ice Shipment

by

Have you heard of Frederic “The Ice King” Tudor? He may sound like European royalty, but he was actually the American founder of international ice shipment (long before people could make their own).

Tudor figured out how to carve ice chunks out of bodies of water – particularly Wenham Lake in Massachusetts – and send it as far away as India and New Zealand by ship!

And did we mention that this was in the 1800s, before refrigeration?

Tudor was initially mocked for his attempts to ship it. Of course, his first attempts were the utter failures one might expect from someone trying to send ice cubes to the Caribbean. (He also spent time in debtor’s prison after being scammed by a business partner.)

Tudor was born in 1783, and by 1820, he had indeed figured out a way to put ice on a boat and send it pretty much anywhere in the world. Perhaps more impressive was his ability to send it to people who had never even seen or heard of ice before. He just convinced them they needed it! (In fact, he played a major role in New Zealand’s booming ice cream industry as a result.)

When the Harvard grad first began his business, he need to purchase his own ship since no ship owners would allow him to rent space on their vessels for a product guaranteed to melt all over the place. Luckily, buying his own ship meant he could control the conditions much more closely.

So, how did Tudor’s international ice shipment production get ice all the way to India and places in between? He insulated giant cubes by packing them in sawdust. Of course, this wasn’t always successful, and there was a tremendous among of ice lost in the process, but there was usually enough to sell by the time it reached its destination. (Even Queen Victoria got her ice from Massachusetts.)

By 1847, he was shipping over 22 tons of ice to foreign ports, three of which were in India. To give you an idea of the accomplishment, that’s a 14,000-mile journey that requires crossing the equator twice.

Of course, Tudor didn’t invent the idea of enjoying ice – the ancient Greeks, Romans, Persians, and Chinese all found ways to store ice during the winter to use during the warmer months. They just didn’t ship it as far as Tudor did.

WTF Fun Facts 12719 – When Weather Kills

by

Heat waves (typically regarded as 3 or more days in a row with a temperature above 90 degrees) are a time to take special care and to check in on the elderly and those with young children who may need help. While the heat makes many of us miserable, it’s also a killer. And because it gets misdiagnosed and is considered a fact of life in the summer by many, we easily forget what a calamity it can be for some (even for those with A/C who experience increasingly frequent power outages!).

Technically, all heat-related deaths are preventable. That’s why it’s so sad that around 658 Americans are killed by extreme heat each year. And the numbers are likely much higher since heat-related deaths aren’t mandatory to report to public health agencies.

Heat deaths as well as deaths in which heat was a contributing factor are easy to misdiagnose or mislabel. Looking back at deadly heat waves in Chicago and Paris, for example, show that far more deaths were related to heat than were recorded at the time.

Here are some sobering facts from the Environmental Protection Agency:

  • Between 1979 and 2018, the death rate as a direct result of exposure to heat (the underlying cause of death) generally hovered between 0.5 and 2 deaths per million people…
  • A total of more than 11,000 Americans have died from heat-related causes since 1979, according to death certificates.
  • In some years, recording has included heat as a contributing factor, and in other years it has not – but in the years where only direct heat deaths “counted,” the estimates may be twice as high as the records show.
  • There was a peak in heat-related deaths in 2006, one of the hottest years on record in the contiguous 48 states.

And while many kids do get special attention during traumatic weather events, it’s the elderly who are often forgotten. However:

  • Since 1999, people aged 65+ have been several times more likely to die from heat-related cardiovascular disease than the general population, while non-Hispanic Blacks generally have had higher-than-average rates.
  • The interaction of heat and cardiovascular disease caused about one-fourth of the heat-related deaths recorded since 1999.

According to the CDC, those most likely to suffer from heat-related illness and death include:

  • infants and children up to 4 years old
  • People 65 years of age and older
  • People who are overweight
  • People who have existing medical conditions, such as diabetes or heart disease
  • People who are socially isolated
  • Those who take medications that impair the body’s ability to regulate its temperature or that inhibit perspiration
  • People who are poor

Behaviors that put people are at risk for serious illness or death during heat waves include:

  • Those who engage in strenuous exercise during high heat
  • People who drink alcoholic beverages during high heat

Heat is also worse in urban areas where buildings, parking lots, sidewalks, and roads absorb heat and create even hotter “heat islands” that aren’t recorded in the local weather estimates.

From 1999 to 2010, 8,081 heat-related deaths were reported in the United States. In 72% of these cases, excessive heat was actually the underlying cause of death (often in those who already had a cardiovascular condition). Only in 28% of cases was it a contributing factor.

So, what can you do to make sure everyone handles the heat?

  • Check on people at risk, such as the elderly, disabled, or homebound.
  • Never leave any living creature locked in a car. (Sometimes we don’t even know how bad the heat is getting to us until it’s too late.)
  • Limit sun exposure during midday hours, even at places like beaches.
  • Avoid sunburn and treat it right away if it happens by applying aloe vera and hot compresses – never pop blisters.
  • Drink plenty of nonalcoholic fluids (and avoid caffeine).
  • Replace the body’s salts and minerals by eating fruits and vegetables (NOT salty snacks – because while your body needs salt, they have too much for your kidneys to handle).
  • Dress in cool, loose clothing (this also helps avoid heat rash).
  • Shade your (and especially children’s) heads and faces from the sun – use an umbrella if that’s all you have.
  • Provide plenty of fresh water for pets and put it in the shade.
  • Create circulation with fans if you don’t have a/c – and make there’s a fan pointing outward to push hot air out of the room.
  • Put a bowl of cold water (with ice, if possible) in front of a fan for an extra cooling effect.
  • Try closing all doors, windows, and curtains right before the sun comes up to keep cooler evening air inside longer.
  • Cover your feet and shoulders with wet towels and washcloths.
  • Create a space in the basement, if you have one, since it’s often cooler down there.
  • Turn off electronics that give off heat when plugged in (such as computers and lamps with incandescent light bulbs).
  • Try not to use the stove or oven.
  • If there’s no relief in your home, visit public buildings (such as shopping malls or libraries) with air conditioning.
  • Avoid large, protein-rich meals to keep the body from creating its own metabolic heat.
  • Lay down in a shaded area and sip water if you get clammy, pale, lightheaded, nauseous, or develop a headache – this can turn into an emergency quickly, so don’t hide away in a hot room.
  • Keep some Gatorade or Pedialyte (or any oral hydration with essential minerals and potassium) to stave off dehydration.
  • Call 911 if you experience: cramps, swelling, fainting, a temperature over 100 degrees and rising, confusion, a rapid pulse, severe nausea, a severe headache, and skin that’s warm and dry – it could be heat stroke, which can lead to coma and death.

WTF Fun Fact 12718 – Crickets Can Tell You The Temperature

by

Let’s get one thing out of the way up front. While we call the method of measuring temperature using cricket chirps “Dolbear’s law,” the idea was first laid out in 1881 by Margarette W. Brooks. Her report “Influence of temperature on the chirp of the cricket” was published in Popular Science Monthly, it just wasn’t noticed until after Amos Dolbear published an 1897 article called “The Cricket as a Thermometer” 16 years later.

Regardless, it’s known as Dolber’s law, and it states that there is a connection between the air temperature and the rate at which crickets chirp. And it’s accurate for the field cricket within about 1 degree Fahrenheit.

It’s kind of like counting the seconds between lightning strikes and thunder, except way more inconvenient.

However, it is true that crickets chirp more speedily as the weather warms up. Dolbear realized this because crickets chirp consistently – that makes it possible to use the numbers in an equation.

In the original paper, Dolbear said you can get the approximate temperature in degrees Fahrenheit based on the times a cricket chirps in 1 minute – but you have to do some more math.

T_{F}=50+\left({\frac {N_{{60}}-40}{4}}\right).
In other words, T = 50+[(N-40)/4]
T = temperature
N = number of chirps per minute

If you want a shortcut for Celcius, you can use the number of chirps in 8 seconds and add 5.

Of course, there are many types of crickets, and Dolbear realized they each had a different rate of chirping. So he created new equations for other species. The problem for us is that we have to know which type of cricket we’re dealing with.

In fact, the common field cricket really isn’t the best cricket to use since its age, and whether it’s mating season can also affect the speed at which they chirp (so they’re not entirely consistent). But they’re probably good enough for a quick experiment. –WTF fun facts

WTF Fun Fact 12717 – Humanity In A Meatball

by

Turns out we’re not much to look at if you were to put all of humanity in a blender and use the solid parts to create a giant meatball.

On a Reddit forum called r/theydidthemath, user kiwi2703 made some gruesome calculations and found that the nearly 8 billion humans on Earth could be blended into a goo sphere that’s actually pretty small, all considering.

We’re not sure what motivated them to come up with this little math trick, but it did make us say “WTF?!” – and that’s why we’re all here, right?

Behold:

[Self] If you blended all 7.88 billion people on Earth into a fine goo (density of a human = 985 kg/m3, average human body mass = 62 kg), you would end up with a sphere of human goo just under 1 km wide. I made a visualization of how that would look like in the middle of Central Park in NYC.

WTF Fun Fact 12713 – da Vinci’s “Helicopter”

by

It’s hard to put into words the genius of Leonardo da Vinci. You have to look beyond his paintings and into his notebooks to see just how masterfully his brain worked. It’s like he understood the secrets of nature in a way no one else could (either then or now).

For example, in the 1480s, he was already imagining ways to create flying machines. And some might call his “aerial screw” the forerunner of the helicopter. That’s an innovation that it took us 400 more years to actually create!

(It’s only fair to mention that de Vinci’s drawing is not the first-ever of a helicopter-type vehicle. In 400 BCE, Chinese Taoist scholar Ge Hong described a “vertical flying machine” made of bamboo in the Baopuzi, though he was referring to a spinning toy. And since Chinese manuscripts made their way to Europe during the Renaissance, da Vinci was possibly influenced by this. It certainly influenced future helicopter inventors.)

Today, we even call the Renaissance artist’s invention “da Vinci’s helicopter” these days, and he wrote an entire treatise on flight. Just look at a page to see what he was capable of:

From: https://airandspace.si.edu/exhibitions/codex/codex.cfm#page-20-21

In the modern world, companies still bicker over who invented the first real helicopter, so it’s just more fun to give credit to da Vinci.

Of course, the aerial screw isn’t the same helicopter we have today. It’s not like he built a gas engine or anything, but he did conceive of a blade that would lift a vehicle vertically off the ground. His blades were not flat but shaped like a screw or helix.

As physicist Tom Hartsfield described in Big Think:

“What da Vinci lacked was the modern materials necessary to construct a lightweight and durable blade. He described the helical screw as being made of linen, with the pores stopped up by starch.

He also lacked the continuous motive power for such a machine. Men turning cranks could never dream of flying: they are far too heavy and too weak to produce enough power to lift themselves…Cognizant of this limitation, da Vinci envisioned aspring, wound by the crank turners, building up and storing energy. That built-up energy could be released in a quick unwinding burst, spinning the screw rotor. But as far as we know, such a device was never built.” — WTF fun facts

WTF Fun Fact 12712 – Pine Cone Hygrometers

by

While we knew plants responded to changes in weather, we must have missed the day our teacher showed the class that we could use a pinecone to gauge humidity.

Now, technically, we feel like walking out into a humid day is enough to make us say, “wow, it’s humid out here.” End of story. But let’s say you’re having a disagreement with a friend about whether it’s humid or just simply hot. THAT’S when it might come in handy to ask a pine cone.

Pine cones open up their scales when the weather is dry (presumably, the evolutionary logic is so their seeds won’t get bogged down too close by and compete with one another when they grow). When the weather is humid, they close back up.

When pine cones are wet in general, their scales swell shut. The outer parts shrink when they’re dry, causing them to pull away from the cone. (This is also why crafters will heat pine cones in the oven before using them. And if you rinse an open pine cone, it will close again.)

Of course, nature is finicky and can take a minute to get the hint, so don’t ask too early in the morning since it may take them some time to get the hint and respond appropriately. But next time you need a science fair project, that seems like a cheap way to do it!

If this is confusing, or you’d simply like to see how it works, check out this oddly mesmerizing video:

WTF Fun Facts 12706 – Oxygen From The Ocean

by

It’s easy to think all our oxygen comes from trees on land – and a LOT of it does (especially rainforests, which there are lots of, and which need protection). But, in fact, most of it comes from the oceans.

That’s a bit harder to believe, but that doesn’t make it less true.

Plankton, specifically phytoplankton, produce most of the Earth’s oxygen. It also serves as food for sea creatures, but they don’t do much else that makes them interesting to most people. They just float around, completely at the mercy of the currents. They’re green and cruddy and you might even look at them and think “eww.”

And that’s fine since they also can’t be offended.

Here’s the deal: even though oceanic phytoplankton isn’t nearly as pretty as trees, it does similar work for us. These little organisms mostly float along the surface of the water or the upper part of the ocean where light still penetrates. They require sunlight to live and grow and produce food for other ocean creatures. They contain chlorophyll to capture the sunlight. If you remember back to grade school science, you probably see where this is going – photosynthesis.

Our oceanic phytoplankton turns the energy from sunlight, as well as carbon dioxide, and mineral salts partly into oxygen. There’s a lot of other stuff going on there too (other byproducts of photosynthesis, like the sugar they feed on), but oxygen is the byproduct we care about at the moment since we need it to breathe.

The cool thing is that even if you don’t live anywhere near an ocean, you still get the benefits because of the way the planet works. Oxygen is great because it just fills the atmosphere and doesn’t need to be shipped via trucks and planes to far-off destinations.

Scientists estimate that 50-80% of the oxygen production that takes place on Earth comes from the ocean. That’s a big range, but even if you go with the more conservative number, it’s clear that we can’t live without them. However, a lot of that oxygen also goes back into the ocean for other ocean life that needs it.

Don’t get us wrong, we love rainforests and regular trees too. But phytoplankton is doing more work than other flora when it comes to keeping breathing creatures alive.

We can do things like track plankton and get some readings off them, but it’s hard to know exact numbers of what they’re producing at any given time. The amount of oxygen they give off can change with the time of day or the time of year. It can also change depending on how healthy the oceans are.

One problem is that things like dead and decaying plants and animals in the ocean also consume oxygen when they decompose. That’s just one reason why killing off aquatic life (such as coral reefs) can be bad for us.

But if you remember one thing, it should be that these tiny, single-celled creatures do a lot of work for us by not only producing oxygen but by absorbing some of the CO2 we emit.

Some people call them “the lungs of the sea.” – WTF fun facts

WTF Fun Fact 12701 – Like A Fish Out Of Water

by

We may not all love bees, but we can’t live without them since they pollinate the crops that make the food we eat (among other integral ecological roles). That makes protecting them integral to our future.

In California, that means considering them “fish” for conservation purposes.

The law is a weird thing sometimes. In this case, it required some creative thinking in order to make sure bees got protected status under the California Endangered Species Act (CESA).

Others had argued that the Act protects only “birds, mammals, fish, amphibians, reptiles, and plants” – in other words, not insects like bees. They won the original court case, but it was just overturned by a Sacramento Court of Appeal.

According to Reuters:

“While ‘fish’ is ‘commonly understood to refer to aquatic species, the term of art employed by the Legislature … is not so limited,’ Associate Justice Ronald Robie wrote for the appeals court.
CESA itself does not define “fish,” but the law is part of the California Fish and Game Code. The code’s definition includes any ‘mollusk, crustacean, invertebrate (or) amphibian,’ Robie wrote. All those categories ‘encompass terrestrial and aquatic species,’ and the state legislature has already approved the listing of at least one land-based mollusk, the opinion said.
‘Accordingly, a terrestrial invertebrate, like each of the four bumblebee species, may be listed as an endangered or threatened species,’ Robie wrote, joined by Acting Presiding Justice Cole Blease and Associate Justice Andrea Lynn Hoch.'”

The case is Almond Alliance of California et al. v. Fish and Game Commission et al, Xerces Society For Invertebrate Conservation et al, intervenors; California Court of Appeal, Third Appellate District, No. C093542.

WTF Fun Fact 12698 – The Universe’s Oldest Water

by

We’re just going to go ahead and admit something to you. When we read about space, the numbers are just too enormous to make much of an impression on us. 140 trillion of anything is just…too big to really imagine, you know?

But when it comes to astronomy, those are the numbers we’re dealing with. Space is just so…vast.

Anyway, that’s all to say that if you look at this fun fact and think “uh, ok, sure,” then you’re not alone.

And the fun fact is that in a galaxy far, far away:

1. Astronomers recently detected a mass of water vapor 12 billion light-years away.
2. That means it took the light from it 12 billion years to reach the earth so we could sense it would our instruments.
3. The cloud of water vapor is located around a quasar, which is a supermassive black hole.
4. There’s not just a little bit of water there, there’s enough water to fill Earth’s oceans 140 trillion (with a T) times.
5. The math tells us that if the cloud is 12 billion years old, then water has been present in the universe much longer than we had imagined.
6. By our calculations, the water was present roughly 1.6 billion years after the Big Bang (aka the beginning of the universe).
7. According to study co-author Alberto Bolatto of the University of Maryland: “This discovery pushes the detection of water one billion years closer to the Big Bang than any previous find.”

Sometimes the universe requires a 7-part fun fact. What can we say?

And if you’re the kind of person who likes to know the details, the quasar the team was studying when they found the water vapor cloud is called APM 08279+5255 and it houses a black hole 20 billion times larger than the sun.

Quasars are the brightest and more powerful objects in the universe, so this one produces 1 quadrillion times the energy of our sun.

Confirmation of the discovery occurred using two different telescopes to ensure the calculations were correct – one was in Hawaii and the other in California.

And while this is a cool find, it doesn’t really change anything about our understanding of how the universe developed since scientists have long assumed that water vapor was probably present very early in the creation of the universe. It was the size of the vapor cloud that surprised astronomers.

So if you feel like your problems are big, just remember that in the grand scheme of things, everything we deal with is really quite small (not unimportant, just small). – WTF fun facts

WTF Fun Fact 12696 – Uranus’ Original Name

by

Uranus – everyone’s favorite planet. Or maybe when you hear the name, you instantly roll your eyes knowing that someone’s about to make a terrible joke.

Either way, many of us know that Uranus is the ancient Greek version of the god of the sky and heavens (and it’s technically pronounced ou-ra-nos, though some people even insist it’s urine-us rather than u-anus). But whatever. The point here is that the planet was originally named George.

And not just George, the Georgium Sidus (or Georgian moon/moon of George).

Until English astronomer William Herschel discovered the bright light was a planet in 1781, everyone assumed it was just another star, or perhaps a comet. The object had been seen before and was recorded in John Flamsteed’s catalog of stars (as “34 Tauri, the 34th star of Taurus the Bull”).

The Herschels were an incredible family of amateur astronomers. William’s sister, Caroline, may have been even more talented, and people knew it! In fact, Maskelyne wrote about the important role played by amateur astronomers right after Caroline discovered her first comet. (Caroline even got a job updating Flamsteed’s catalog of stars, the Historia Coelestis Britannica.)

Another fun fact? In the 1800s (and long before and shortly after), science could hardly be done without a rich person’s funding. Herschel wasn’t even considered to be a professional astronomer at the time – he also fell into the ranks of an “amateur.” In fact, the official Royal Astronomer, Nevil Maskelyne, still had to confirm it was a planet before it could be declared one. Even then, it was until astronomer Johann Elert Bode double confirmed it that the object was accepted by a planet by the scientific community (which is how you make it really official, not just “royal official”).

According to NASA, its mistaken identity as a star is understandable. The planet is extremely far from the sun and moves incredibly slowly (so much that half of it is plunged into ice-covered darkness for 21 years at a time). So you’d have to watch the object for decades to notice it even acts like a planet – that’s the kind of dedication required! It’s pretty much invisible to us now because of the light pollution the Earth emits.

But back to the George – Uranus thing.

William Herschel really wanted royal patronage (aka money) to fund his endeavors. So in order to gain favor with King George III, he used his fame as the person who discovered the first new planet since antiquity to advocate for the name George.

But George didn’t exactly fit with the naming scheme astronomers had going on at the time, which was all mythology-based. So in the end, it was Bode who got his way, naming the planet Uranus.

Of course, Herschel got the credit and the benefits that followed. And now we all get to tell Uranus jokes until the end of time (but it’s Bode we have to thank for that). – WTF fun facts

WTF Fun Fact 12695 – Male Mice Are Scared Of Bananas

by

We may have never noticed on our own that male mice harbor a fear of the humble banana. But scientists studying the fear responses of male mice to pregnant and lactating female mice made the connection.

Long story short, male mice can be very aggressive towards baby mice (or “pups), especially virgin male mice who see them as genetic competition. That’s why female mice have evolved to produce a compound, called n-pentyl acetate, in their urine that produces a stress and fear response in all male mice (but especially virgins).

Bananas enter the equation because they also happen to emit a compound that produces a fear response in male mice. They don’t contain n-pentyl acetate but rather isoamyl (or isopentyl) acetate.

Of course, bananas didn’t evolve to scare mice, that’s just a coincidence.

According to IFL Science:

“The team bought banana oil extract from the supermarket and placed it inside the cages of male mice to measure their stress levels, which increased significantly in response. The team believe that the stress response in the mice is similar to the stress response when about to engage in a fight.”

At least now we know one more strategy for getting rid of male mice! – WTF fun facts

WTF Fun Fact 12689 – The World’s First Gardens

by

While the practice of growing plants and flowers for aesthetic pleasure hasn’t been a characteristic of all times and places, gardening goes back thousands of years. There is evidence of Egyptian palace gardens in the second millennium BCE! And they were so large it was said that oarsmen could row their boats through their water features.

Of course, agriculture existed long before that, but gardening (or ornamental horticulture), was designed purely for pleasure (not for medicinal purposes alone) once people settled down.

While some trace the oldest gardens to China, those acted more as hunting lands. Other ancient references to “gardens” (such as in the Epic of Gilgamesh) were likely patches of trees and not purely ornamental agriculture.

In the 6th century BCE, gardening was in full bloom. The Babylonians had the Hanging Gardens of Babylon, which the Hellenistic Greeks referred to as one of the Seven Wonders of the Ancient World.

There were gardens at the schools of ancient Greece (Aristotle kept one) and all over Rome. In fact, the Romans were obsessed with gardening. The architectural author Vitruvius wrote the first book on landscaping.

After the decline of Rome, the Moors kept the tradition alive in the West (along with much of Western intellectual tradition) while a separate culture of gardening developed in China and spread to Japan. Monks also copied Roman gardening manuscripts and kept gardens of their own, penning some original gardening manuals as well.

Purely ornamental gardening fell out of fashion (or, well, people didn’t quite have time for it) in the middle ages. But it was revived again in France in the 13th century to some extent and boomed again in the Renaissance period.

In the 16th century, the Spanish were the first to build public parks. – WTF fun facts

WTF Fun Fact 12683 – From New Hampshire to Norway

Right before the pandemic closed schools, students at New Hampshire’s Rye Junior High School were working on a science project to launch a boat into the ocean with GPS attached to see where it would end up and what route it would take.

According to NPR: “Rye Junior High and the nonprofit Educational Passages — which says it aims to connect students around the world to the ocean and one another — started working together on the project in 2018, according to a release. The organization provided students with an assembly kit in 2020, though the construction and launch were complicated by the coronavirus pandemic.”

They thought it was lost when GPS stopped transmitting for a while, but eventually, it pinged again from a little uninhabited island off the coast of Norway. They just needed someone to retrieve it. Enter local sixth-grader, Karel Nuncic, who took a boat with his parents and puppy out to the island (which they could see from their coastal home) to recover the vessel. It wasn’t in great shape, but the hull containing artwork from the students who launched it was intact and dry.

In a Facebook post, the school said:

“RJH’s miniboat made it across the Atlantic! Our students put together a 5 foot drifter and had it launched into the middle of the Gulf Stream current on Oct. 25, 2020. Which way did it go? The onboard GPS recorded its location, most of the time. Then it went silent for a while. On Sunday, it pinged again and its location was on a small island off of Norway! Stayed tuned for more of the story! Here are the before and after photos of our miniboat and a map of its path. (Thanks to Educational Passages and The Clipper Foundation!)”

WTF Fun Fact 12677 – How To Survive A Date With A Spider

by

In many species of spiders, the last thing males do is mate. After that, they’ve done their job for the evolution of the species and are no longer needed. So females have evolved to simply eat them. They provide nutrients for the babies, after all!

It’s called sexual cannibalism and it’s one of the many facts of nature that we humans may have a hard time wrapping our heads around (or not, depending on your mate).

A few species have evolved to avoid this fate – for example, some may choose to amputate their own legs as a defense strategy in order to distract the females and get away (with the remaining legs, of course). In some sense, this makes sense since the female gets some nutrients and the male gets to hobble away with his life. It just seems a bit drastic from a human perspective.

Other spiders have learned to weave silk around the legs of the females before mating so they can make an easier escape afterward, which seems like a wise move as long as the female survives to produce her young.

The Philoponella prominens have developed a strategy whereby they use their two front legs to propel themselves out of reach of the females, getting away with all of their legs and their lives (if they hit the eject button in time, at least).

Since Philoponella prominens don’t have venom, the males who get cannibalized are in for a rough ride before death. The females produce over 400 feet of silk to “mummify” them, typically winding it so tight that they’re crushed and/or suffocated.

Not only are these spiders interesting for their actions but how they achieve them. Most jumping spiders launch from their back legs, so jumping using the front legs leads to some more interesting questions about the evolution of these creatures, especially since they don’t have muscles in those legs.

According to Smithsonian Magazine, the researcher who made this discovery noted that “one male was able to perform the behavior six times over the course of about eight hours, but was finally killed and eaten after his final performance–perhaps being too exhausted to spring himself to safety.”

WTF Fun Fact 12672 – Beware the “Sharkcano”

by

Your mother probably warned you not to swim around acidic shark-infested volcanoes, but in case she didn’t, we’re telling you now not to try it!

Only once have scientists been able to explore the Kavachi volcano in the Solomon Islands. It’s a submarine (aka underwater) volcano and it actually erupts almost constantly. But in 2015, it took a break, giving researchers the chance to check it out.

And boy did they find some stuff! It’s no surprise that they found high levels of sulfur (because it is a volcano, after all), but they were surprised to see that despite extremely acidic conditions, some creatures have managed to thrive in the craters.

There are microbial species that are common in sulfuric environments. There are also “gelatinous animals and small fish.” Oh, and a whole bunch of angry sharks.

According to IFL Science, oceanographic researchers said this is “raising new questions about the ecology of active submarine volcanoes and the extreme environments in which large marine animals can exist.”

And while that’s really cool, we’re more interested in the phenomenon they dubbed “sharkcano.” The researchers wrote: “Two species of shark, the scalloped hammerhead Sphyrna lewini and the silky shark Carcharhinus falciformis, approached the baited camera multiple times in an aggressive pattern; in some cases, sharks appeared to be swimming from greater depths inside the crater.”

Now, before you picture thousands of sharks spewing out from the depths of the ocean floor (which is the first thing we pictured), it’s definitely not going to be that wild if this volcano has a major eruption. It will, however, be a really bad time to go swimming in that area.

NASA images showed a plume developing in late May, so we may be in for a sharkcano eruption sometime soon and we’ll be able to see precisely what that entails. –  WTF fun fact

WTF Fun Fact 12665 – The Initials On the Moon

by

Eugene Cernan walked on the moon twice, during the Apollo 10 and Apollo 17 missions. The Apollo 17 mission, which took place from December 7–19, 1972 was NASA’s final Apollo mission and the last time a human was on the moon. Cernan boarded last, making him the last man to set foot on the moon’s surface.

During Apollo 17, Cernan and his fellow astronaut, Harrison Schmitt spent 22 hours and 6 minutes outside, and they still hold the record for the longest extravehicular activity on the moon.

Cernan then drove the lunar rover about a mile away from the takeoff site so it could photograph the ship’s take-off the following day. Before he walked back to the lunar lander, he wrote in his autobiography that he knelt by the rover and drew his daughter Tracy’s initials into the moon dust.

Cernan spoke these words as he climbed into the lunar lander and left the moon:

“As I take man’s last step from the surface, back home for some time to come – but we believe not too long into the future – I’d like to just (say) what I believe history will record. That America’s challenge of today has forged man’s destiny of tomorrow. And, as we leave the Moon at Taurus–Littrow, we leave as we came and, God willing, as we shall return, with peace and hope for all mankind. Godspeed the crew of Apollo 17.”

The crew returned safely to Earth on Dec. 19, 1972. –  WTF fun fact
