WTF Fun Fact 13360 – Plant Machete Robot

“Plant machete robot” are three words we never expected to hear together. And yet here we are.

That’s because David Bowen, a renowned kinetic artist, is pushing the boundaries of the relationship between technology and art. His latest exhibition, “Plant Machete” showcases his unique ability to fuse nature with machines. The result is a portrayal of plant life that is truly mesmerizing – and a bit dangerous.

A machete-wielding plant robot

Bowen described the piece on his website:

“Plant machete has a control system that reads and utilizes the electrical noises found in a live philodendron. The system uses an open source micro-controller connected to the plant to read varying resistance signals across the plant’s leaves. Using custom software, these signals are mapped in real-time to the movements of the joints of the industrial robot holding a machete. In this way, the movements of the machete are determined based on input from the plant. Essentially the plant is the brain of the robot controlling the machete determining how it swings, jabs, slices and interacts in space.“

Art meets tech

“Plant Machete” prompts viewers to question the boundaries between the organic and the mechanical. Bowen’s robotic machete, while purely mechanical, seems to breathe with life as it mimics the internal signals of the. It’s a testament to Bowen’s genius that he can draw such lifelike behavior from an inanimate object.

Bowen’s work sparks conversations about the interplay between nature and technology. As a result, we get a reminder of the connection between these worlds. The robotic machete brings the unseen world of plants to the surface. It also provides a unique perspective on the intricate dances of nature.

According to his website, Bowen “is a two-time recipient of a McKnight Visual Artist Fellowship and has received awards such as Grand Prize, Japan Media Arts Festival; Honorary Mention, Ars Electronica; and Third Prize, Vida Art and Artificial Life international competition. Bowen has been an artist in residence at Autodesk Pier 9, The Mattress Factory Museum of Contemporary Art, The Massachusetts Museum of Contemporary Art and The Arctic Circle.”

WTF Fun Fact 13348 – May Dew

Do you know about the mystical powers of “May Dew”?

In Europe (particularly Ireland and Scotland), people believed that the dew that adorned grass and plants during May mornings possessed extraordinary powers.

Spring rituals

According to folklore, the magical moisture had the power to enhance beauty and preserve youthfulness. It was said that washing one’s face with this dew would give a person radiant, youthful skin. This belief was deeply rooted in countries like Ireland, Scotland, and England, where May Day rituals and celebrations were an integral part of the cultural fabric.

The all has its roots in ancient customs and nature reverence. On the first day of May, people celebrate May Day, which signifies the transition into the vibrant season of spring. As a result, they view the gathering of dew as a means to harness the life-giving energy of nature.

The ancient ties of morning moisture possessing magical properties stem from its association with purity and renewal across many cultures. The arrival of May, considered a time of abundant growth and fertility, intensifies the potency of the dew collected during this period.

May dew rituals

The rituals are often carried out before sunrise on May Day. People would venture into meadows and gardens, carefully collecting the dew that glistened upon leaves and petals. Some would simply wash their faces with it, believing it would bless them with a radiant complexion. Others would capture the precious liquid in containers, creating potions and cosmetics said to possess healing and beautifying qualities.

While the belief in May Dew has waned in modern times, it continues to leave a lingering trace in cultural folklore. The allure of this tradition lies in its connection to nature’s bountiful energy and the desire to harness its magic. It serves as a reminder of the ancient customs that shaped our relationship with the natural world.

WTF Fun Fact 13345 – The Australian Emu War

You may have learned about quite a few deadly conflicts in school, but have you ever heard about the Australian Emu War? Also called the Great Emu War in Western Australia, it was exactly what it sounds like – a war against emus. As in the animals.

The origins of the Australian Emu War

The Great Emu War occurred in Western Australia in 1932. It was a conflict between Australian farmers and a large population of emus. Emus are flightless birds native to Australia, in case you didn’t know.

This war was no joke. An uncontrolled emu population began to encroach on farmlands, damaging crops, and creating economic problems for the farmers. In response, the farmers requested military assistance to deal with the emu infestation.

According to Atlas Obscura (cited below):

“Western Australian farmers had been facing hard times with their crops following the Great Depression, and their difficulties increased tenfold with the arrival of some 20,000 emus migrating inland during their breeding season. The birds had been protected as a native species until 1922, but now that they were classified as ‘vermin,’ all bets were off.”

The Australian government actually deployed soldiers armed with machine guns to combat the emus. , They saw the animals as a threat to agriculture. However, emus are also fast and agile. That makes them difficult to eradicate with weapons.

A war of futility

One might think the mismatch was the result of humans having the advantage of deadly weapons. But it was really the emus who had the upper hand.

To top it off, emus don’t want to fight. So when they hear gunfire, they run. That makes them much harder to target. It also had the effect of separating the battalions into smaller and smaller groups to go after the scattering emus. That’s just bad military planning.

In the end, the army realized that using precision weapons was ineffective and called off the operation. The emus won.

The Emu War has become symbolic of human struggles against the forces of nature and the limitations of technology in dealing with wildlife. It was no doubt a humbling experience for the military.

Eventually, the government turned to other – less violent – measures. They erected fences to protect farmlands from emu intrusion.

So, it turns out violence wasn’t the answer.

WTF Fun Fact 13341 – Parrot Video Calls

Parrots are social animals. That’s why they don’t always make the best solo pets. However, recently, researchers have given pet parrots a new way to thrive after teaching the birds to use technology to make parrot video calls.

Parrot playtime with video calls

Researchers from Northwestern University, MIT, and the University of Glasgow conducted the study. With the help of some parrot parents, the team successfully trained parrots to communicate with each other.

Over several months, participants taught captive African grey parrots to use a custom-built video-calling system. First, researchers trained the birds to use touchscreens mounted inside their enclosures with easy-to-understand symbols and icons representing different contacts. The researchers rewarded their interactions with food treats. As the birds grew more comfortable with the devices, they were gradually introduced to video calls, first with their handlers and later with other parrots.

Parrots embrace technology

The African grey parrots demonstrated a remarkable ability to learn and adapt to the use of the video-calling system. Not only were they able to initiate calls, but they also showed preferences for specific contacts, indicating that they understood the purpose of the technology and were actively seeking social interaction through the calls.

The study found that the parrots were more likely to engage in video calls when they were alone in their enclosures. This suggests that the video-calling system provided social stimulation and companionship, especially in the absence of human interaction. The introduction of video-calling technology in captive settings could potentially improve the quality of life for these intelligent and social animals.

So, it turns out parrots like to video chat with one another just like humans do, and that it makes them feel less lonely. Many birds in the study stayed on the calls for the maximum allotted time and still choose to call their buddies from the research study over a year later.

According to Northwestern University:

“The most popular parrots were also the ones who initiated the most calls, suggesting a reciprocal dynamic similar to human socialization. And while, in large part, the birds seemed to enjoy the activity itself, the human participants played a big part in that. Some parrots relished the extra attention they were getting from their humans, while others formed attachments for the humans on the other side of the screen.”

WTF Fun Fact 13338 – Monkey in the Mirror

It’s not until we’re around 2 years old that we figure out what the mirror is showing us. And not all animals can recognize their own reflections. But if you train a rhesus monkey in the mirror, it will the first thing it’ll do is check out its genitals.

The monkey in the mirror

A 2015 study found that rhesus monkeys are capable of recognizing themselves in mirrors and engaging in self-exploration behaviors, but only after some training. The research helps shed light on the cognitive abilities of non-human primates and their level of self-awareness.

The researchers trained a group of rhesus monkeys to touch a red dot on their faces after seeing it in a mirror. This task is commonly used to test an animal’s ability to recognize itself in a mirror and is considered a measure of self-awareness. It’s called the “standard mark test.”

It took several weeks of training for rhesus monkeys to pass the standard mark test. But, eventually, they were able to recognize themselves in the mirror and understand that the reflection was a representation of their own bodies.

The first thing the monkeys did after that? Umm. Let’s just say they engaged in a range of self-exploration behaviors.” And they started with their own genitals.

Monkey see

The rhesus monkeys didn’t spend all their time “down there” though. They eventually moved on to the nose and mouth, behavior similar to what has been observed in chimpanzees and orangutans.

The act of inspecting their own genitals may seem amusing, but it actually provides insight into the cognitive abilities of non-human primates. The ability to recognize oneself in a mirror is considered a measure of self-awareness. And that’s a crucial component of consciousness.

Self-awareness allows animals to engage in complex social behaviors, such as empathy, cooperation, and deception.

Rhesus monkeys’ ability to recognize themselves in mirrors and engage in self-exploration is significant because it suggests that they have a level of self-awareness that we previously thought unique to humans.

The study also has implications for our understanding of animal welfare. Animals that are self-aware are more likely to experience emotions, including pain, fear, and stress. This means that they may be more susceptible to negative welfare impacts, such as confinement and isolation.

If we understand the cognitive abilities of non-human primates, we can work towards improving their welfare.

WTF Fun Fact 13337 – Light Pollution

Usually, when we think about pollution, we’re worried about smelling it or ingesting it somehow. Simply seeing it isn’t thought of as dangerous. But did you know light itself could be a sort of “pollutant”? Light pollution is a growing problem that is affecting us and our planet in many ways.

What is light pollution, and how does it hurt us?

Light pollution is the use of artificial light that is excessively bright or misdirected. For example, when streetlights or buildings shine light upwards into the sky. Sure, we need a lot of our street lights to keep us safe on roads and sidewalks, but so many lights and lights that are shining so broadly or brightly can really mess up our sleep and our ecosystem.

For starters, excess and misdirected light has serious consequences for nocturnal animals. It can disrupt their migration patterns, feeding habits, and breeding cycles. And as we know, everything on earth is interconnected in some way.

But light pollution also has a direct negative effect on human health. Our exposure to artificial light at night can interfere with our circadian rhythms. So think about how much light you can still see in your room when you shut off your light fixtures. Can you still see lights from streetlamps? Billboard? Store signs? Neighbors’ holiday decorations?

Exposure to light can lead to a range of health problems, including sleep disorders, obesity, and depression. It can also disrupt our hormones.

A waste of energy

Light pollution also requires energy consumption. And as we know, this can produce greenhouse gas emissions. So by reducing light pollution, we can help our ecosystem, ourselves, and reduce the energy consumption that negatively impacts our future.

What can we do to address the problem of light pollution? One solution is “dark-sky friendly” lighting. This means using lighting fixtures that are designed to minimize the pollution. It wouldn’t involve installing all new light fixtures. Rather, it involves the use of shields or hoods that would direct light downwards (which is where we need it to see roads and sidewalks anyway) instead of upwards. Using these fixtures can reduce the amount of excess and misdirected light while keeping us safe.

Most people don’t even know about light pollution and how it affects them. But once they do, they generally take steps to reduce their own contributions to it. (And we bet the neighbors are grateful!)

Reducing your light output might mean turning off unnecessary lights at night, using lower-wattage bulbs, and making sure outdoor lights only shine downwards.

If you’re seeking some darkness in order to see the stars at night, check out the International Dark-Sky Association. It’s a nonprofit organization that works to preserve and protect the night sky, and it has designated more than 100 Dark Sky Places around the world, including parks, cities, and communities that are committed to reducing light pollution and preserving the beauty of the night sky.

WTF Fun Fact 13336 – Oceans with More Plastic Than Fish

Imagine a world where the oceans have more plastic in them than fish (by weight). Well, if you’re still around in 15 years, you might not have to imagine it.

Do our oceans have more plastic than fish?

According to the WWF (cited below):

“Whilst plastic has revolutionized our way of life since it was invented in the 1950s, the problem is that most of the plastic ever made still exists. The amount of plastic in the ocean is expected to double in the next 15 years, and by 2050 there could be more plastic than fish in the sea (by weight).

There are giant plastic islands floating on the ocean surface, and beaches around the world are increasingly littered with plastic rubbish even in the Arctic. It may come as a shock to know that most of the plastic in the ocean is out of sight, either underwater or on the ocean floor….90% of seabirds have plastic in their stomachs and half of marine turtles have eaten plastic. Sea life chokes on plastic rubbish or gets tangled in it, often causing a painful slow death. And plastic pollution is contributing to the breakdown of coral reefs.”

Wow, that’s depressing.

What’s the problem with plastics?

The problem with plastic is that it doesn’t biodegrade like other materials. Instead, it breaks down into smaller and smaller pieces, called microplastics, which stick around for centuries. Microplastics enter the food chain and accumulate in the bodies of land animals and marine life. This obviously effects humans eventually too.

Our plastics end up affecting over 700 species of marine animals, including sea turtles, dolphins, and whales. These animals can become entangled in plastic debris or mistake plastic for food, leading to starvation or blockages in their digestive systems.

Plastic disrupts the entire ecosystem. For example, plastic debris can alter the flow of water, which can affect the movement and distribution of plankton, the base of the marine food chain. This can have ripple effects throughout the ecosystem, ultimately impacting human populations that rely on the ocean for food and income.

How did we get to this point?

Plastic is cheap and convenient and people don’t like to be inconvenienced or have their minds changed. The use of plastic has become ubiquitous and we show no signs of giving it up (soggy paper straws aren’t going to solve the whole problem).

Another problem is that we don’t properly dispose of or recycle plastic. Researchers estimate that we’ve only recycled around 9% of all plastic ever produced, and we send the majority to landfills. So now it’s accumulating.

Addressing industries will be a big step. For example, the clothing manufacturing, carpet, and soft drink industries use huge amounts of plastic. Of course we can reduce our use of single-use plastics, but curtailing the use of plastics in manufacturing is going to have a much bigger effect than banishing your plastic baggies. You can help by supporting policies and regulations that promote sustainable practices and reduce plastic waste.

Another important step is to properly dispose of plastic waste can prevent it from entering the environment and ultimately ending up in our oceans. That’s another job primarily for industries, but we can do our part as individuals as well.

Want to do something immediately to support conservation efforts to reduce plastic pollution in the ocean? You can participate in beach cleanup if you live nearby a body of water. Otherwise, an email or phone call to the politicians you vote for is a good start.

WTF Fun Fact 13335 – Fast Fashion Pollution

Cheap clothing is convenient, and changing out our wardrobes every season might make us feel more fashionable, but fast fashion pollution is a bigger problem than we imagined.

The United Nations named the fashion industry the second most polluting industry in the world. It produces 8% of all carbon emissions, 20% of all global wastewater, and uses about 93 billion cubic meters of water annually. The fashion industry is responsible for more carbon emissions than international flights and global shipping combined.

Fast fashion pollution

According to a study published in the journal Water (cited below), the fast fashion industry is a major contributor to water pollution since these brands produce large quantities of clothing at a rapid pace. This leads to excessive water usage as well as the release of harmful chemicals into our waterways.

The study found that fast fashion brands use up to 2,700 liters of water to produce a single cotton t-shirt. This excessive water usage can lead to the depletion of water resources in areas where water is already scarce.

The industry also contributes to water pollution through the use of hazardous chemicals in the manufacturing process. Many brands use synthetic dyes and chemicals that can be harmful to the environment and human health.

The disposal of fast fashion clothing also contributes to water pollution. Many fast fashion items are made from synthetic materials that do not biodegrade, leading to them ending up in landfills or incinerators. The disposal of these items can release harmful chemicals into the air and leach into nearby waterways.

How to make it stop

Well, money talks. You can always invest in clothing that lasts or repair the clothing you have.

To address the water pollution associated with fast fashion, companies do try to implement more sustainable manufacturing practices. But it’s unclear to what extent this really works if they’re still selling so many garments.

Some fast fashion brands are incorporating recycled materials into their products, reducing the amount of virgin materials needed and the associated water usage. Others are implementing closed-loop systems, which recycle water and chemicals used in the production process.

But in the end, consumers may play the biggest role in reducing the water pollution associated with fast fashion. Choosing to buy clothing made from sustainable materials and produced using sustainable manufacturing practices is an option. But a better one is reducing clothing waste by donating or recycling clothing to keep textiles out of landfills and reduce the pollution associated with textile disposal.

WTF Fun Fact 13334 – Getting Electricity from Mud

How can you get electricity from mud? Well, it turns out there’s a bacteria for that.

In a fascinating development that could have huge implications for the future of energy production, scientists have discovered a species of bacteria called Geobacter sulfurreducens produce tiny wires called pili that allow them to transfer electrons from mud to metals or other conductive materials.

Pulling electricity from mud

Geobacter sulfurreducens belongs to a group of organisms called electrogenic bacteria. They’re unique in that they are able to transfer electrons from organic matter to metals or other conductive materials. This process is known as extracellular electron transfer. It allows the bacteria to generate electricity using devices called microbial fuel cells (MFC).

Generating electricity from mud could be useful for powering small devices in remote areas where traditional power sources aren’t available. Since the bacteria can be easily cultivated in large quantities, the equipment needed to generate electricity from mud is relatively simple and inexpensive. That can also make it a good option for developing countries or areas where traditional power sources are unreliable.

The bacteria could also be used for environmental cleanup. It’s even an environmentally friendly technology since the bacteria consume organic waste and produce electricity as a byproduct.

A broader trend

While this may all seem beyond belief, scientists have actually been using bacteria to generate electricity for a while. They have experimented with wastewater, food waste, and even human urine. The hope is that these bacterial technologies can eventually help us address climate change, energy security, and environmental degradation.

Of course, there are some serious challenges to face before we can implement this kind of tech. For example, it requires massive amounts of bacteria to generate a decent amount of electricity. So there are valid concerns about the scalability of this technology. Then there are the obvious ethical concerns people have about using living organisms to help clean up messes humans have made.

Despite all this, the potential of bacteria-based electricity generation may play an important role in shaping our future.
