WTF Fun Fact 13331 – The Midlife Slump

by

Some people tend to feel a sense of existential dread, sadness, or disappointment in life in their 40s or 50s. But this “midlife slump” is perfectly normal. Just don’t confuse it with the caricature of the midlife crisis where everyone runs out and buys red sports cars or has affairs.

Studying the midlife slump

According to research, people in “middle age” often experience a dip in happiness and life satisfaction between the ages of 40 and 50. One study even pinpointed the most miserable age – 47.2. Of course, that’s just an average, so don’t plan for it. The good news is this dip is usually temporary. In fact, after the slump is over, people tend to become happier as they age.

The midlife dip in happiness is caused by a combination of factors. The reality of an aging body, financial pressure, having to take care of both children and elders and the plain old realization that your life is half over (if you’re lucky). It seems to be all downhill from there.

Bouncing back

However, studies also find that people tend to rebound from the midlife slump with gusto. And they become happier as they age. In fact, one study found that people tend to be happiest in their 70s and 80s! Apparently, a sore body is no match for the satisfaction brought by wisdom. With age comes greater contentment and well-being!

So if you’re feeling a bit blue about hitting the big 4-0 or 5-0, take heart in the fact that the midlife slump is a normal part of the aging process. You can even make it a time for self-reflection and growth rather than drowning in your own misery. Some people use this time to make positive changes in their lives. You might start a new career, pursue a lifelong dream, take stock of your priorities, and begin to surround yourself with the people who matter.

Is a midlife crisis different?

The term “midlife crisis” was first coined in 1965 by psychologist Elliot Jaques. He used it to describe a period of self-doubt and reflection. But it only applied to his male patients. It wasn’t until many decades later that people realized women at this age were also struggling – they just deal with it differently and were more likely to seek help.

The classic “midlife crisis” isn’t a given. But it can be triggered by major life events that typically happen in one’s 40s or 50s. This can include the death of loved ones, divorces, job losses, and a general sense of unfulfillment. People find themselves asking “Is this it”? It’s a bit different from the midlife slump, which is a measure of happiness. And happiness is something internal.

Whatever kind of midlife rut you might find yourself in, take heart in the fact that it may be an opportunity for positive change.

WTF Fun Fact 13229 – Wild Spring Weather

by

Spring weather is known for its unpredictability. Some days are warm and sunny and make you look forward to summer. Other days are full of chilly rain and even snow. Spring is a transitional period, and understanding the factors that contribute to spring weather’s wackiness can help us prepare for its unpredictable nature.

Why is spring weather so wild?

One of the main factors that contribute to the unpredictability of spring weather is the balance of cold and warm air. The atmosphere is trying to balance the cold air left over from winter with the warm air that starts to move in from the southern hemisphere (which just had its summer). This creates unstable weather patterns that fluctuate wildly from day to day.

Another significant contributor to spring weather’s unpredictability is the jet stream. The jet stream is a high-altitude wind current that flows from west to east, and it’s the most active during the spring season. Its presence can cause disturbances in the atmosphere and lead to changes in air pressure, temperature, and precipitation.

The jet stream can create a wave-like pattern in the atmosphere. This can cause pockets of cold and warm air to mix together, leading to dramatic temperature changes. It also creates a barrier between these warm and cold air masses. This leads to severe weather like thunderstorms, tornadoes, and even blizzards.

The jet stream can also affect the timing and severity of tornadoes and hurricanes.

Here comes the sun

The changing angle of the sun is another factor that impacts spring weather. As the sun gets higher in the sky and the days get longer, the amount of energy the Earth receives increases. This can lead to unstable air masses and subsequent thunderstorms.

If you live near a large lake or an ocean, you’ll probably notice that the weather is even more unpredictable. That’s partly because water takes longer to warm up than land, so the mixture of cold and warm air creates unstable air masses that cause things like thunderstorms.

While spring weather’s unpredictability can make it challenging to forecast accurately, there are some patterns that can help us prepare for what’s to come. For example, in North America, the eastern part of the continent tends to experience more significant temperature swings than the western part. In the western part of the continent, spring tends to be a more stable season. Of course, with global climate change, who knows how predictable anything will be in the long or short term?

Some research suggests that as the planet warms, we may start to see even more extreme weather events in the spring, including more severe storms and rainfall.

WTF Fun Fact 13325 – Spring Daylight

by

In spring daylight increases each day by 2-3 minutes. This helps the world awakens from its winter slumber. As the days get longer and the sun begins to shine brighter, it’s a reminder that winter is behind us and summer is just around the corner.

How does spring daylight increase?

The increase in daylight during the spring season is a result of the Earth’s axial tilt and position in its orbit around the sun. During the spring equinox, the Earth’s axis is tilted neither toward nor away from the sun, resulting in equal amounts of light and darkness. After the spring equinox, the Northern Hemisphere begins to tilt more toward the sun. This is what leads to longer days and shorter nights.

Gaining light

Throughout the spring season, the amount of daylight increases by approximately 2-3 minutes each day. This adds up to a significant increase in total daylight hours by the end of the season. By the time the summer solstice rolls around in late June, some places in the Northern Hemisphere can experience as much as 17 hours of daylight.

This increase in daylight has an impact on both the natural world and human behavior. For plants, the longer days provide more opportunities for photosynthesis. For humans, they provide more opportunities for outdoor activities and recreation. This increase in activity can have a positive impact on physical and mental health. Exposure to sunlight has been shown to boost mood and energy levels.

Despite the many benefits of longer daylight hours in the spring, one notable challenge is the loss of sleep that can occur when the clocks “spring forward” for daylight saving time. But in the end, most people agree that springtime gives them a feeling of renewal.

WTF Fun Fact 13320 – The Fear of Other People’s Opinions

by

Allodoxaphobia is the name for fear of other people’s opinions. It’s a relatively uncommon phobia, but it can affect individuals of all ages and backgrounds. People with allodoxaphobia can experience intense anxiety and distress when confronted with opinions that differ from their own. They may also fear being asked to share their own opinions.

Fearing other people’s opinions

The word “Allodoxaphobia” comes from the Greek words “allo” (meaning “other”), “doxa” “meaning “opinion”), and “phobia” (meaning “fear”). Researchers typically associate this phobia with social anxiety rather than just rejecting other people’s opinions. In fact, it can have a significant negative impact on an individual’s personal and professional life (then again, so can rejecting other people’s opinions).

Symptoms of allodoxaphobia can vary widely and will depend on the severity of the phobia. Some allodoxaphobics have physical symptoms like sweating, shaking, and nausea. Others may have emotional symptoms like intense fear, panic, and avoidance of situations where opinions are likely to be expressed.

How does a person develop allodoxophobia?

The causes of allodoxaphobia are not fully understood. Like many phobias, it’s likely caused by a combination of genetic, environmental, and psychological factors. Some researchers suggest that individuals with a history of anxiety or other mental health conditions may be more likely to develop allodoxaphobia.

Treatment for allodoxaphobia typically involves therapy. But in severe cases, anti-anxiety medication may be in order, especially for someone with a severe phobia that they are trying to overcome through exposure therapy.

Therapists often recommend cognitive-behavioral therapy and different types of psychotherapy along with lifestyle changes like relaxation techniques.

Are we afraid of opinions that don’t match our own?

This phobia is very rare. People who get upset by competing opinions are not necessarily phobic.

People who have irrational reactions to conflicting opinions aren’t necessarily allodoxaphobic. Rather, they may simply lack emotional maturity, the vocabulary to explain their opinion (which can lead to frustration, or be concerned that their opinion will reveal a lack of knowledge on the topic that would embarrass them. These are not the same things as a phobia, which is a medical diagnosis.

However, anger or fear towards the opinions of others can be addressed through self-help techniques or with the help of a qualified mental health professional if they interfere with a person’s life.

In some cases, allodoxaphobia appears to be related to a fear of change or a fear of being wrong. These people may also feel a strong need for certainty and control, which can make it difficult for them to accept differing opinions or beliefs.

While it is normal and healthy to have personal opinions and beliefs, it’s important to remember that everyone has the right to their own thoughts and feelings. By learning to be open-minded and respectful of differing opinions allodoxaphobic people can overcome their fear of other people’s opinions and lead more fulfilling lives. But it can help all of us cope with everyday life in the 21st century.

WTF Fun Fact 13319 – Solar Panel Production

by

As nations throughout the world work to decrease their carbon footprint and transition to renewable energy, solar panel production has increased significantly in recent years. China is one of the major players in the solar panel business thanks to its extensive production and inexpensive prices. Yet, the U.S. is making efforts to catch up and reclaim its position as a global leader in the manufacture of solar panels.

Dominance in solar panel production

China controls 80% of the global solar panel market and is now able to sell solar panels for far less than businesses in other nations. However, there has been increasing concern about China’s use of forced labor, particularly of the Uyghur population, in the production of their solar panels.

While it’s not clear how many solar panels produced in China use forced labor, given the scale of the industry and the reports of human rights abuses in the region, there have been calls for the solar industry to ensure that their supply chains are free from forced labor and other human rights abuses.

U.S. attempts to corner the solar supply chain

The United States is gradually catching up to China’s solar industry thanks to rules and incentives put in place to encourage domestic production and consumer uptake. For example, the US Bipartisan Infrastructure Bill (BIL) has set aside money for the procurement of raw materials, manufacturing, and utility-level adoption.

Additionally, American businesses are funding emerging technologies that might transform the manufacturing of solar panels so it no longer needs to rely on China for raw materials, such as polysilicon. Thin-film solar panels, for instance, which are being tested by some businesses and could bring down the price of solar panels and increase consumer access to them.

In 2021, the United States installed over 20 gigawatts of solar capacity (bringing the total installed capacity to 142.3 gigawatts), which accounted for 50% of new electricity.

WTF Fun Fact 13318 – The Science of Spring Flower Growth

by

Many people eagerly await the first signs of spring. One major clue is the emergence of new plants, including a few colorful flowers. Of course, many plants wait until the ground thaws and the temperature warms up before starting to grow. But the science of spring flower growth is complex. And some flowers have a unique adaptation that allows them to bloom even in the coldest of conditions.

Two flowers you may have seen early in the year are crocuses and snowdrops. These actually have the ability to push through frozen soil and snow to bloom in early spring! It’s all made possible by a special adaptation in their cells that allows them to expand and contract with changes in temperature.

The science of spring flower growth

This adaptation in a few flowers is due to a process called thermoperiodism. This requires a cycle of low and high temperatures in order to help trigger growth.

Here’s how it works: The cells in these flowers contract when the temperatures drop. This causes a vacuum that draws water and nutrients from the soil into the plant. The cells begin to re-expand as the temperatures climb. This expansion and contraction push the flowers through the frozen ground. Pretty cool, right?

Now, these early-blooming flowers depend on this ability to survive. By blooming early, they are able to take advantage of the increased sunlight. They also get early pollinators (like bees and butterflies) that are essential for their reproduction. And they don’t have to compete for these resources.

Crocuses and snowdrops are also popular flowers for their beauty and variety. Crocuses come in a wide range of colors, including purple, white, yellow, and pink. They can be found in both single and multiple petals. Snowdrops, on the other hand, are known for their unique bell-shaped flowers – typically white or pale green.

While crocuses and snowdrops are among the most well-known flowers that can push through frozen soil and snow, they are not the only ones. Other early-blooming flowers include winter aconite, Siberian squill, and hellebore.

WTF Fun Fact 13313 – Driving Phobia

by

For many people, driving is a mundane and necessary part of daily life. But driving phobia affects a small percentage of people, causingf intense anxiety and fear. This condition is known as vehophobia, which is defined as a persistent and irrational fear of driving.

According to Trauma Research UK, vehophobia can have a variety of causes, including a traumatic driving experience, a previous accident, or a fear of losing control. Other common triggers include driving on highways, bridges, or in heavy traffic, and driving at night or in bad weather conditions.

How does driving phobia manifest?

Vehophobia can manifest in a number of ways, including physical symptoms such as sweating, shaking, and heart palpitations, as well as psychological symptoms such as panic attacks, avoidance behavior, and hypervigilance.

For those who suffer from vehophobia, the impact can be significant. It can limit one’s mobility, interfere with daily activities, and even cause relationship and employment issues.

Fortunately, there are a number of treatments available for vehophobia. Cognitive-behavioral therapy (CBT) is a common approach that can help individuals identify and challenge negative thoughts and beliefs about driving. Exposure therapy, which involves gradually exposing the person to driving-related situations in a safe and controlled environment, can also be effective.

In addition to therapy, there are several self-help strategies that can help alleviate symptoms of vehophobia. These include deep breathing, progressive muscle relaxation, and visualization techniques. Joining a support group or online community of individuals who share similar fears and experiences can also be helpful.

It is important to note that vehophobia is a real and serious condition that can greatly impact one’s quality of life. If you or someone you know is struggling with vehophobia, seek help from a qualified mental health professional. With the right treatment and support, it is possible to overcome this fear and regain confidence behind the wheel.

WTF Fun Fact 13311 – Lungs As Big As Tennis Court

by

It sounds pretty impressive to have lungs as big as a tennis court. But it’s true for all of us.

How are lungs as big as a tennis court?

The surface area of the lungs is about 70 to 100 square meters. That’s roughly the size of a tennis court. This is due to the intricate network of tiny air sacs called alveoli found within the lungs. The average adult has a total lung capacity of around 4-6 liters.

The alveoli are incredibly small. In fact, each one measures only about 0.3 millimeters in diameter. However, they are numerous. An estimated 480 million alveoli exist in the lungs of an average adult. These tiny air sacs are the places where the exchange of oxygen and carbon dioxide takes place. This is what allows us to breathe and provides our bodies with the oxygen needed to function.

Our amazing lungs

To help with the process of breathing, the lungs are surrounded by a thin layer of muscle called the diaphragm. When the diaphragm contracts, it pulls downward and creates a vacuum that allows air to flow into the lungs. When the diaphragm relaxes, it pushes upward and forces air out of the lungs.

Did you know that lungs are not identical in size or shape? The right lung is larger. It has three lobes, while the left lung is smaller and has only two lobes. This asymmetry allows for space to be made for the heart, which is located on the left side of the body.

The lungs are also the only organ that can float on water. That’s because they’re composed mostly of air, which is less dense.

Lungs even have the ability to regenerate and repair themselves. That’s due to the stem cells in the respiratory system. This regenerative capacity is especially important in combating respiratory diseases such as chronic obstructive pulmonary disease (COPD) and lung cancer.

WTF Fun Fact 13310 – Fingernail Growth

by

Fingernail growth is a fascinating topic. For example, have you ever wondered why your toenails seem to grow at a slower rate than your fingernails? Or why nails on one hand seem to grow faster?

The science behind fingernail growth

It’s important to understand the anatomy of nails. Nails are made of layers of a protein called keratin. The area of skin beneath the nail is called the nail bed. Blood vessels and nerves run through the nail bed, providing nourishment to the nail.

Toenails vs fingernails

So why do toenails grow more slowly than fingernails? Well, toenails receive less blood flow than fingernails. The blood vessels that supply the nail bed with nutrients and oxygen are smaller in the feet than in the hands. This means toenails don’t have access to the resources they need to grow as quickly. This is also why toenails are more prone to fungal infections than fingernails. The reduced blood flow makes it more difficult for the body to fight off infection.

Growth factors

Another factor that affects the growth rate of nails is the amount of physical activity we engage in. Research has shown that physical activity can increase blood flow to the nail bed. This can lead to faster nail growth. An active person who spends a lot of time on their feet may have toenails that grow faster than someone who spends most of their time sitting.

Age and health also impact nail growth. For example, as we age, our nail growth rate tends to slow down. Certain medical conditions (such as hypothyroidism or psoriasis) can also cause nails to grow more slowly or become brittle and prone to breakage.

The growth rate of nails can even vary depending on the season. Nail growth is faster in the summer than in the winter. Researchers found that nail growth rates were highest in August and lowest in February. This suggests that sunlight exposure and changes in temperature may play a role.

WTF Fun Fact 13308 – Smart Slime

by

Have you ever heard of “smart slime”?

Physarum polycephalum is a type of slime mold. Fun, right? Well, it’s actually found in many natural areas around the world. If you run across it, throw it a puzzle!

This mold is capable of solving complex mazes and other spatial problems without a brain or nervous system. Ok, not a boxed puzzle.

Despite lacking a brain, this organism has navigated mazes and established efficient routes between food sources. Scientists still don’t know what to think.

How does “smart slime” work?

So how does Physarum polycephalum do it? According to some researchers, the key lies in the way that this slime mold processes and responds to information.

Humans and other animals rely on centralized nervous systems to process and interpret information from the environment. But slime molds are decentralized and they exhibit a more distributed form of intelligence.

One striking example of this distributed intelligence can be seen in the way that slime molds navigate mazes. When placed in a maze with multiple food sources, slime molds are able to explore and test different paths! They gradually identify the most efficient routes between the food sources. This ability has been attributed to the slime mold’s ability to sense and respond to different environmental cues. In other words, they can sense the presence of food, humidity, and light. But it’s a whole extra step to use that information to solve problems!

Some researchers have suggested that the slime mold’s ability to solve spatial problems may be related to its ability to process information in a way that is fundamentally different from known forms of intelligence. For example, one study found that Physarum polycephalum is capable of solving the “shortest path problem.” This involves finding the shortest route between two points in a network.

Humans typically solve this problem by analyzing and comparing different routes. But slime mold is able to accomplish the same task by physically growing and adapting to the network itself. Say what?!

Nature loves a puzzle

Despite its remarkable abilities, Physarum polycephalum is still a subject of ongoing research and debate among scientists. Some researchers believe that the slime mold’s distributed intelligence may hold the key to developing new forms of artificial intelligence. Other people are understandably freaked out by that.

Many scientists are focused on understanding the fundamental biological mechanisms underlying its behavior before they go trying to turn it into a monster.

One thing is clear: the slime mold’s abilities are truly remarkable. As we continue to study and learn from this fascinating organism, we may even discover new insights into the nature of intelligence, adaptation, and evolution itself.

WTF Fun Fact 13307 – Project Pigeon

by

During World War II, the United States government developed a program to train pigeons to guide missiles to their targets. This program was known as Project Pigeon or Project Orcon. It was developed by psychologist B.F. Skinner and was intended to provide an alternative to radio-controlled guidance systems, which were vulnerable to jamming and interference.

Using animals in technology

The idea behind Project Pigeon was simple: Skinner would train pigeons to peck at a target on a screen, and their pecking guided a missile to its target. To prove this, Skinner trained the pigeons to associate the target with food and were able to peck accurately and consistently, even under stressful conditions.

The military ultimately discontinued the program in favor of other guidance systems. But the concept of using animals to guide technology has continued to be a topic of interest and research in modern times. Today, researchers are exploring the use of trained animals such as dogs, rats, and even bees to detect and respond to various stimuli, including explosives, drugs, and diseases.

What was Project Pigeon?

During World War II, the United States government needed to develop an effective guidance system for missiles and other weapons. Radio-controlled systems had proved vulnerable to jamming and interference, and researchers were eager to explore alternative approaches.

Psychologist BF Skinner believed that he could train animals to guide missiles to their targets. His idea was based on the principle of operant conditioning, which he had developed through his work with laboratory animals.

The basic idea behind Skinner’s approach was to train pigeons to associate a target on a screen with the release of food. He then placed the pigeons in the nose of a missile, where they would peck at the target on the screen. This would send signals to the missile’s guidance system and steer it toward its target.

Skinner’s idea eventually received support from the military. The military developed it into a program known as Project Pigeon or Project Orcon. They trained of hundreds of pigeons, housing them in special compartments in the nose of the missile.

While the program never saw actual use in combat, it did succeed in demonstrating the potential of animal-guided technology.

WTF Fun Fact 13300 – Swearing and Exercise

by

Exercise often needs to be hard to be productive. And that can be a frustrating experience. Maybe that’s why swearing and exercise go together to make you more productive. That’s right, recent research has suggested that swearing during exercise can help to alleviate pain, improve performance, and even reduce stress.

How swearing and exercise go together

According to a study published in the journal Psychology of Sport and Exercise, swearing during exercise can help to reduce the sensation of pain. For example, the study found that people who swore while squeezing a hand grip held on for longer and reported less pain than those who did not swear. That’s because swearing triggers the body’s fight-or-flight response. And this can help to increase pain tolerance and reduce the sensation of discomfort.

“Swearing appears to be able to bring about improvements in physical performance that may not be solely dependent on a stress response arising out of the shock value of the swearing,” Richard Stephens, the study’s co-author, said.

In addition to reducing pain, swearing can also improve performance during exercise.

A study found that athletes who swore before completing a physical task were able to produce more power and strength than those who did not swear. Letting out some choice curse words can increase your adrenaline levels and provide you with a burst of energy. These same things can help athletes perform at their best.

Let it out

Finally, swearing can also help to reduce stress and anxiety during exercise. That’s because swearing can help to regulate emotions and reduce feelings of stress and anxiety. It provides a cathartic release, which can help to improve mental wellbeing.

While swearing during exercise may not be suitable for everyone, there appear to be a number of benefits to using profanity during physical activity.

So next time you hit the gym, don’t be afraid to let out a few choice words – it could be just what you need to improve your performance and reduce pain and stress.

WTF Fun Fact 13299 – Caffeine and Adenosine

by

Caffeine doesn’t actually give you energy. That buzzed feeling you get when you drink coffee or soda is actually due to an interesting relationship between caffeine and adenosine in your brain that simply tricks you into thinking you’re not tired.

How do caffeine and adenosine work?

Caffeine is one of the most widely consumed stimulants in the world. Many people rely on caffeine to stay awake and alert. But have you ever wondered how caffeine actually works to keep you awake?

Contrary to popular belief, caffeine doesn’t actually give you energy. It actually works by blocking the action of a chemical called adenosine in the brain.

Adenosine is a naturally occurring chemical in the brain. It builds up throughout the day as the brain uses energy. As your adenosine levels rise, these chemicals bind to adenosine receptors in the brain. This, in turn, triggers a response that makes you feel tired and drowsy.

Caffeine works by blocking the adenosine receptors in the brain. This prevents adenosine from binding to those receptors and triggering tiredness.

So, by blocking adenosine, caffeine essentially tricks the brain into thinking that it’s not tired, even though it doesn’t actually provide any extra energy.

Most of us use caffeine to help us feel more awake and alert. But it’s important to know that it doesn’t actually provide any extra energy. In fact, caffeine doesn’t provide any calories or nutrients at all! It’s simply a chemical that alters the way the brain and body function. Interesting, right?

How can we get more energy?

So, caffeine can’t actually boost your body’s real energy reserves. But you can get more energy through the consumption of calories in the form of carbohydrates, proteins, and fats. When we eat food, our bodies break these down into glucose.

Glucose molecules are transported into our cells and then broken down through chemical reactions that release energy in the form of ATP (adenosine triphosphate). This true energy is then used by our cells to power a wide range of biological processes. THAT’S how you really get more energy.

In addition to consuming calories, getting enough sleep, staying hydrated, and engaging in physical activity can all help improve energy levels. These are the ways you can truly feel more alert and focused throughout the day.

WTF Fun Fact 13298 – A Rollercoaster Cure for Kidney Stones

by

Roller coasters are known for their stomach-churning twists, turns, and drops. But did you know that these thrilling rides may have a surprising health benefit? How about a roller coaster cure for kidney stones?

Well, according to recent research, riding a roller coaster really can help people pass the stones.

Kidney stones are a real pain

Kidney stones are hard, mineral deposits that form inside the kidneys. They can be incredibly painful and cause symptoms like back or abdominal pain, nausea, and difficulty urinating.

In some cases, surgery or other medical interventions may be necessary to remove them. But for smaller stones, riding a roller coaster may be a more fun and natural solution.

The idea that roller coasters could help pass kidney stones came from a patient who reported passing a stone after riding the Big Thunder Mountain Railroad roller coaster at Disney World. Intrigued by this anecdote, urologist David Wartinger from Michigan State University set out to investigate further.

To test the theory, Wartinger and his team created a 3D-printed model of a human kidney with three small stones inside. Then they took it on several roller coaster rides. They found that the Big Thunder Mountain Railroad ride at Disneyland in Orlando, FL really was highly effective at dislodging the stones from the kidney.

After the ride, the stones were able to pass through the urinary tract more easily, reducing the need for medical intervention.

How do roller coasters help “cure” kidney stones?

Why do roller coasters have an effect on passing kidney stones? It has to do with the forces generated by the ride. During a roller coaster ride, the body experiences a range of movements, including sudden drops, sharp turns, and rapid accelerations. These movements create a force called acceleration. This acceleration can jostle kidney stones and potentially dislodge them from the kidney.

Of course, riding a roller coaster isn’t a guaranteed cure for kidney stones, so don’t buy that ticket to Disney just yet. The size, location, and type of stones can all affect whether or not a ride will be effective. Additionally, riding a roller coaster may not be practical or advisable for everyone, especially those with other health conditions or mobility issues.

We need more research to understand the effects of roller coaster rides on kidney stones completely. But for now, this serves as an interesting example of how unexpected solutions can sometimes be found in unlikely places.

WTF Fun Fact 13296 – Keanu Reeves’ Chemical Compound

by

Keanu Reeves is such as lethal presence on the silver screen that scientists have named a fungus-killing bacteria after him. That’s right, Reeves is now getting recognition in an unexpected field – mycology. The name isn’t inspired by his reputation for “down-to-earth” kindness and generosity though. It’s inspired by his efforts as a stealth killing machine in the film series John Wick.

The Keanu Reeves compound

The compound, called “Aptostichus keanu,” was discovered by researchers at the University of California, Riverside. It belongs to a class of compounds called cytochalasins, which have been shown to have antifungal and anticancer properties. Aptostichus keanu is particularly effective against fungi that cause diseases in crops, making it a potentially valuable tool in agriculture.

According to Smithsonian Magazine (cited below), scientist Sebastian Götze theWashington Post’s Kyle Melnick:

“We were just basically blown away by the high activity. That’s why we basically said, ‘Yeah, it’s like an assassin, a hit man or something, killing a couple of different fungi very effectively.’”

Thekeanumycin compound bleeds the fungal pathogens to death by creating holes in the surface of fungal pathogens. Kinda like stabbing.

Keanu saves the crops

Even better is the fact that Reeves’ namesake compound might be a natural, effective fungicide that helps save crops.

“In a study recently published in theJournal of the American Chemical Society, lead author Götze and his colleagues describekeanumycins’ strength against a common plant pest that causes a gray mold rot. CalledBotrytis cinerea, it affects more than 200 types of fruits and vegetables, including strawberries and grapes, per the statement. The researchers usedkeanumycinsto significantly clear this blight from hydrangea leaves,” reports Smithsonian.

This isn’t the first time a celebrity has had a scientific discovery named after them. In recent years, new species of animals and plants have been named after David Bowie, Lady Gaga, and Barack Obama, among others. These names are often chosen as a way to honor the person’s contributions to society or their cultural significance.

While Aptostichus keanu may not have the same level of cultural impact as Keanu Reeves’ films, it’s still an exciting discovery with potential applications in agriculture and medicine.

As for Reeves’ response to the whole this: it was priceless. During a Reddit question-and-answer session he answered a question about his namesake:

“They should’ve called it John Wick. But that’s pretty cool … and surreal for me. But thanks, scientist people! Good luck, and thank you for helping us.”

WTF Fun Fact 13294 – Sounds of the Northern Lights

by

The Northern Lights, also referred to as aurora borealis, are a natural phenomenon that has long stunned humans and sparked imaginative explanations. The phenomenon occurs when charged particles from the sun collide with the Earth’s magnetic field. This causes the eerie yet beautiful display of light that most of us will only see pictures of. But did you know that scientists have long been obsessed with the sounds of the Northern Lights?

The sounds of the Northern Lights

It appears that the Northern Lights also produce sound, even though they occur in the vacuum of space. According to a recent article in The Conversation (cited below), scientists have recently detected sounds associated with the aurora borealis.

People have reported hearing things for over a century. But there has never been any scientific evidence to back it up. In a 2016 Finnish study, a researcher published his confirmation that the lights really do produce sound. He even made a recording to prove that it’s audible to the human ear. But not everyone is convinced. Even those who believe the lights could make sound insist it should not be audible to the human ear.

Some scientists suggest the sounds are caused by the interaction of the sun’s charged particles with the Earth’s magnetic field. As the particles collide and interact with the magnetic field, they create vibrations. These vibrations can be picked up by specialized equipment, such as radio receivers. However, they still shouldn’t be audible to us. That’s because they’re at frequencies that are much lower than what we can hear.

A continuing mystery – or mystery solved?

According to The Conversation, a Canadian astronomer has provided the most convincing evidence of the sounds of the Northern Lights.

“The answer to this enduring mystery which has subsequently garnered the most support was first tentatively suggested in 1923 by Clarence Chant, a well-known Canadian astronomer. He argued that the motion of the northern lights alters Earth’s magnetic field, inducing changes in the electrification of the atmosphere, even at a significant distance.

This electrification produces a crackling sound much closer to Earth’s surface when it meets objects on the ground, much like the sound of static. This could take place on the observer’s clothes or spectacles, or possibly in surrounding objects including fir trees or the cladding of buildings…”

While Chant’s hypothesis went largely unnoticed in the 1920s, scientists revisited it in the 1970s.

Today, “Chant’s theory is largely accepted by scientists today, although there’s still debate as to how exactly the mechanism for producing the sound operates.”

As the author, historian of science Fiona Amery, notes:

“What is clear is that the aurora does, on rare occasions, make sounds audible to the human ear. The eerie reports of crackling, whizzing and buzzing noises accompanying the lights describe an objective audible experience – not something illusory or imagined.”

Of course, in addition to producing sound, the Northern Lights are known for their stunning visual displays. They are typically seen in places close to the Earth’s magnetic poles, such as the Arctic and Antarctic regions.

They’ve become a popular tourist attraction in these areas. Scientists continue to study the phenomenon in order to better understand the mechanisms behind this natural “light show.”

WTF Fun Fact 13292 – Earthquake Lights

by

Earthquakes can generate electromagnetic waves that are detectable by animals hours or even days before the actual event occurs. This phenomenon is known as the “earthquake lights” or “seismic lightning” and is still not fully understood by scientists.

The strange phenomenon of earthquake lights

Have you ever heard of “earthquake lights” or “seismic lightning”? This phenomenon has intrigued scientists for years. The lights appear to be the result of electromagnetic waves. Their faint glow appears to be detectable by animals (and certain forms of technology).

Regardless of its origin, this phenomenon has the potential to provide valuable insights into the physics of earthquakes.

According to National Geographic (cited below), “Earthquake lights can manifest themselves in different ways, from a faint, diffuse glow on the horizon to flame-like streamers emanating from the ground.” They can appear in a variety of colors, including white, blue, yellow, and red.

These lights have been observed in various forms, including:

  • luminous clouds
  • flashes of light
  • glowing balls of light that hover over the ground

Predicting earthquakes

Studies have shown that some animals, including dogs and horses, are able to sense the electromagnetic waves produced by earthquakes. As a result, they may exhibit unusual behavior before an earthquake strikes.

Similarly, some researchers believe that the lights themselves may be an early warning sign of an impending earthquake. Eventually, this could allow us to prepare and evacuate before the shaking begins.

These lights have been observed for centuries. But they remain poorly understood by scientists who are still working to determine how and why they are produced. Some suggest that they are the result of electrical charges building up in rocks and soils under stress. Others propose that they may be related to the release of gases from the Earth’s crust.

In 1965, residents of Matsushiro, Japan, witnessed a spectacular display of earthquake lights before a major earthquake struck the area. The lights appeared as bright, white flashes that seemed to be coming from the ground. The earthquake, which had a magnitude of 7.0, caused significant damage in the region.

WTF Fun Fact 13287 – The First Spacewalk

by

On March 18th, 1965, Soviet cosmonaut Alexei Leonov made history by becoming the first person to walk in space. Leonov left his spacecraft, the Voskhod 2, and floated in space for 12 minutes and 9 seconds. The first spacewalk paved the way for future space exploration and opened up new possibilities for scientific research in space.

The Soviets made the first spacewalk

The spacewalk was a remarkable achievement for the Soviet space program, which was in competition with the United States at the time to achieve milestones in space exploration. The mission was not without its challenges, however. Leonov’s space suit had inflated in the vacuum of space, making it difficult for him to move and causing him to experience overheating.

Despite these challenges, Leonov successfully completed his spacewalk and returned to the spacecraft, where he faced another problem. The spacecraft’s automatic landing system had failed, and Leonov and his crewmate had to manually steer the spacecraft to a safe landing.

Subsequent spacewalks

Since Leonov’s historic feat, many other astronauts and cosmonauts have followed in his footsteps (or rather, lack of footsteps). Here are some quirky facts about spacewalking:

  • The longest spacewalk in history was conducted by Russian cosmonauts in 2013. They spent 8 hours and 7 minutes outside the International Space Station.
  • Spacewalks are often referred to as “EVA,” which stands for “extravehicular activity.”
  • Spacewalkers wear special suits called Extravehicular Mobility Units (EMUs). These are designed to protect them from the extreme conditions of space.
  • During a spacewalk, astronauts and cosmonauts tether themselves to the spacecraft to prevent them from floating away into space.
  • The first American to conduct a spacewalk was Ed White in 1965, just a few months after Leonov’s historic walk.
  • In 1984, American astronaut Bruce McCandless made history. He became the first person to fly freely in space without being tethered to a spacecraft.
  • The first all-female spacewalk took place in 2019. Astronauts Christina Koch and Jessica Meir conducted a 7-hour walk to replace a failed power controller.

As space exploration continues to advance, it’s likely that we’ll see even more remarkable achievements in spacewalking. But Alexei Leonov’s historic spacewalk on March 18th, 1965 opened up a new world of possibilities for space exploration.
