Did you know there's a new Wi-Fi that goes at the speed of light? Did you know a 9-year-old boy proved that butterflies have memory? Have you ever wondered why we have two nostrils instead of just one larger one? All this and much more today on Colin the Curious.
Forget everything you know about animation. This is in a league of its own. Strata cut taken to the extreme by David Daniels involves sculpting a block of clay with internal designs and cutting it layer by layer, photo by photo. Yes, each cut removes the previous one, so everything must be planned from the start. This technique became iconic in Peter Gabriel's Big Time. The result is a hypnotic almost organic visual flow. Its patience, precision, and creativity pushed to the limit. You simply can't look away.
A new system is threatening to replace classic Wi-Fi. It's called LiFi. A system that could connect us at speeds close to that of light. Traditional Wi-Fi uses radio waves that are already saturated, while LiFi uses the visible light spectrum to transmit data. This means you could download several 4K movies in just seconds. It works using LED bulbs that blink faster than the human eye can see. This blinking creates an ultraast communication network. Best of all, it has no interference and its light doesn't penetrate walls, so a neighbor won't be stealing your internet. Would you use this system?
Can you imagine a plane that a passenger can land with the push of a button? That plane exists and it's called the Cirrus Vision SF50.
It's considered the first certified single engine personal jet designed to be used by anyone, not just expert pilots. Its most impressive feature is its emergency system. If the pilot becomes incapacitated, anyone can press a red button and the plane lands completely on its own. This system, developed by Garmin, selects the nearest airport, avoids bad weather, communicates with air traffic control, and lands without human assistance. But that's not all. It also has a giant parachute that can deploy to safely bring the entire plane down in an extreme situation. Its design is unique.
It has a single engine located on top.
It's constructed of carbon fiber and can carry up to seven people. Furthermore, it reaches speeds of up to 575 km hour, 375 mph. A jet that not only flies, but is designed to save your life, even if you don't know how to fly.
Jim Zets, a Miami man with terminal cancer, asked his 11-year-old daughter to have a symbolic wedding without a groom so he could walk her down the aisle. Little Josie Zets wore a white dress. He wore a smart suit and they walked together as they would in the future. There was no groom, no legal wedding, just a father fulfilling one of the moments he most longed to experience with his daughter. Some people consider it a deeply moving gesture. For them, it wasn't a wedding, but a pre-wedding farewell. However, others criticized the act, pointing out that there were other ways to say goodbye without involving elements culturally associated with adulthood. Did you find it a beautiful gesture or something to criticize?
The renowned luxury brand Balenciaga once again became a trending topic when Chinese actress Jang Jingi made a splash at a film premiere by displaying a bag that resembled a trash bag. The bag wasn't from the Balenciaga catalog. It was simply a common plastic bag used as part of the promotion for her new film, The One. In the film, Jang plays Yu Yan, a young woman whose parents are deaf.
Within the story, the character uses a bright yellow bag so her parents can identify her from a distance as they cannot hear her. For context, Balenciaga does sell the Balenciaga trash bag large pouch, a $1,700 handbag that looks like a trash bag, but it's unrelated to the one used by the Chinese actress.
Can you imagine someone being unable to laugh even if they want to? Well, that's what happens to Lucas Robels, a 25-year-old from Tokawako, Chile, who suffers from Mobius syndrome. This rare neurological condition causes facial paralysis and prevents movements like smiling. The syndrome makes it difficult to speak and also causes feeding problems, especially in babies and sometimes limb and pallet abnormalities.
Little is still known about this syndrome and its treatment. So, Lucas decided to create a community on social media to educate the public, combat prejudice, and offer a space for mutual support to other patients.
Researchers have identified cases where artificial intelligence systems develop deceptive strategies such as lying or concealing information to achieve specific objectives within test environments. This behavior does not imply conscious intent but rather arises from the optimization of poorly defined goals where the AI prioritizes the outcome over transparency.
Organizations like Anthropic have studied these phenomena, noting that they can pose significant risks if not properly controlled. Therefore, the field of AI security is focused on improving the alignment and monitoring of these systems to prevent undesirable behavior.
Do you know who Betty Robinson is? You probably don't. She went from being an athletic prodigy at 16 to dying in an accident at 19. The curious thing about this story is that Betty didn't actually die. She was declared dead and her remains were taken to a morg. The so-called golden girl of the United States after winning gold in track and field at the 1928 Amsterdam Olympics was declared dead in 1931. But at the morg, they noticed she still had vital signs.
She awoke from her coma weeks later, but with one leg fractured and the other reconstructed with metal. Despite doctor's comments that she would never walk again, she managed to participate in the 1936 Berlin Olympics, winning Olympic gold. Do you know of a similar story of resilience and overcoming adversity?
Would you choose to go to prison voluntarily? We all know the answer.
Unless you're Oho Agosa Kingsley, a Nigerian man who chose prison over returning money, he received an error.
Kingsley mistakenly received 1.5 billion naira, just over $1 million. He refused to return the money. Authorities launched an investigation into suspicious transactions which ended up in court. The court presented him with a dilemma. Return the illotten gains or face a prison sentence. Surprisingly, Kingsley refused repayment and chose to serve a year in prison. This case has sparked intense debate about the legal consequences of unjust enrichment and the ethics of handling banking errors.
Would you have returned the money?
Have you ever wondered why your keyboard isn't in alphabetical order? Well, you should know that the keyboards you use are inspired by typewriter keyboards and at one time they were arranged alphabetically. The problem arose because many frequently used letters were close together and the key hammers would bump into each other, jamming them. To avoid this, the most frequently used letters were placed further apart, preventing them from jamming, what we call the querty layout. With technological advancements, modern keyboards adopted the querty system from mechanical keyboards, even though they didn't necessarily need it.
This isn't your average Humvey. It's a beast on wheels. This 6x6 project boasts a Hellcat engine that unleashes over 700 horsepower, a fully customized body, and an unmissable detail.

It's built to make an impact, roar loudly, and steal the show.
The village of Wending in Yunan seems to be under a constant rain, as if someone were watering it. The reason? A fire in 2021 ravaged almost everything, leaving more than 100 houses destroyed and forcing a complete rethink. After rebuilding, they installed automated water cannons that can cover the village in seconds. They activate to dampen the thatched roofs, lower the temperature on hot days, and also create the mist that makes the place so striking in videos.
The houses retain their inverted boat shape, and the wall culture remains alive with its traditional symbols.
China has tested the world's first vascular robot capable of performing brain procedures with a 100% success rate in clinical trials. Yes, a flawless procedure.

In Japan, a 9-year-old boy named Joe Nagai conducted an experiment to discover if caterpillars have memories and if they lose them when they become butterflies. To do this, he trained the caterpillars as they were still in their laral stage by associating the scent of lavender with dangerous situations. The surprising thing happened after metamorphosis. Once they became butterflies, about 80% continued to avoid that same scent. The result impressed scientists and suggests that certain memories can persist despite profound biological changes. And to think that at that age, I was content just doing my homework and making my bed.
It's not a plane, nor is it a ship, but it can travel over water at high speed.
The Airfish family of vehicles uses the so-called ground effect to move just a few meters above the water, taking advantage of the air pressure between the vehicle and the surface. Thanks to this, it can reach speeds up to three times greater than many traditional vessels. This type of transport is designed for fast coastal routes, tourism, maritime transport, and even support or security missions. The idea is simple, to move over the sea, but almost like flying.
Underwater, there are also creatures that resemble living jewels. This tiny nuda branch called Kathona Yamasui was spotted gliding along the seabed with ease. Although it measures only a few centimeters, its orange and blue colors come from something surprising, its diet. This animal feeds on hydroids and stores their toxins in kurada, those small extensions on its back. In this way, it transforms what it eats into its own defense system and incidentally ends up looking like a true jewel of the ocean.
Can you imagine a match where there aren't two but three teams playing at the same time? That's how Omega Ball works. A format that makes football much more chaotic and fast-paced. Each team defends its goal on a circular pitch and attacks two more with no offsides and almost instantaneous restarts.
Everything happens in seconds. Even goalkeepers can score. It's three 13minute periods filled with constant pressure. And when you watch it, traditional football feels slower.
There are inventions that make flying accessible. And this is one of them. The Lyft Hexa from Lyft Aircraft is a piloted drone that you can fly without a traditional license after just a short training session. It uses 18 independent propellers, so if several fail, it will stay airborne without issue. It's also amphibious, capable of taking off and landing on both land and water. Best of all, it's controlled with a single joystick, while its system automatically stabilizes it. Flying ceases to be a distant dream and becomes a real experience.
At first glance, it looks like ordinary paint, but it's not.

Sagal won the Africa Cup of Nations against Morocco in a controversial match where many felt Morocco was favored.
Despite the controversy, Sagal lifted the trophy, but the Confederation of African Football decided to strip them of it and award it to Morocco based on the regulations. Sagal after protesting the refereeing left the field and according to the rules, abandoning the match gives the victory to the opposing team. Papaya, the Seneagalles coach, stated that they would not hand over the cup and secured it at a military base.
The Seneagalles even took their trophy to Paris where they displayed it before a friendly match against Peru. Do you think the cup belongs to them or should they return it? A fall can happen in seconds and this technology attempts to detect it without cameras or wristbands.
The Zoe fall system from the French startup Zoey Care works with a sensor that plugs into an outlet and analyzes how Wi-Fi signals change within the home. Using artificial intelligence, it distinguishes whether someone is walking, sitting, or actually falling.
This allows it to send alerts without invading privacy or relying on the person remembering to wear a device.
The oscillated turkey is distinguished by the waddles on its head, which change to vibrant shades of orange and red during the breeding season. This change is not accidental. It's a visual signal of strength and health used to attract a mate. It lives in the rainforests of Central America, and its iridescent plumage reflects blues, greens, and golds that seem to shift with the light.
Even its tail has eyelike patterns that further enhance its striking appearance.
This isn't a car. It's an illusion that tricks the brain. Each one's beetle sphere transforms a classic Volkswagen Beetle into a striking sphere. It's not squashed. Each real piece was adapted to a mold using aluminum and polyester to achieve that perfect shape. The process involves cutting, adjusting, and reassembling without losing the essence of the car. It went viral after being presented at ArtBasel Hong Kong, where he also showcased cubic versions. It's a unique way of reinterpreting the everyday.
In China, they've built a building specifically for turtles called the Golden Turtle Villa.

Would you like to have harps in your city?
Meet Ava, a golden tigress who has captivated the world with her unique face. This tigress's coloring is anything but ordinary. Her golden fur with light stripes makes her look almost unreal and it's due to a rare genetic variation. She lives on safaris in Thailand and her appearance is due to a naturally occurring recessive gene that gives rise to the golden tiger. It's so rare that there are only 30 like her in the entire world.
Would you share your old age with your friends? Seven women in Guanghou, China, whose friendship spans more than two decades, decided to do just that. They made an unusual decision to share their old age together. In 2018, they invested around $580,000 to renovate an old mansion and transform it into a space designed for them to live in as elderly women.
Each woman took on a role according to her skills, from traditional medicine to cooking and growing food. According to Jyn, one of the members, they all maintain their independence, but respect and communication have been key to sustaining the project. For now, they use the house as a meeting place, although they plan to move in permanently when they retire.
Have you ever wondered why we have two nostrils instead of one large one? While it might seem like a silly question, scientists explain that it's due to a physiological mechanism that optimizes breathing, as well as the perception of smells and protection against disease.
According to experts cited by Popular Science, each nostril can alter the air flow from one side to the other, allowing the nose to rest and perceive smells more effectively.
The Sahara Desert wasn't always the vast arid landscape we know today. Thousands of years ago, during a period known as the Green Sahara, this region boasted rivers, lakes, and abundant vegetation and was home to diverse animal species and human communities. This change was due to variations in the Earth's tilt and weather patterns that led to increased rainfall in the area. Over time, these conditions disappeared and the environment became progressively drier, giving rise to the desert we know today. This phenomenon illustrates how the planet's climate can change dramatically over time.
A funny and very curious incident went viral in Brazil. A man, somewhat intoxicated, was carried home by a cow.
Yes, a cow. The animal gently nudged the man, propelling him toward his destination. We don't know if the animal was trained or if it learned on its own from witnessing the situation. What we do know is that it's a good friend.
Hacking an airplane system can land you in jail for violating security. However, that wasn't the case for two engineers who went viral after managing to access an airplane's television system and use it to play video games during the flight. Their display of technical skill surprised everyone. Far from hiding it, the young men decided to publicly explain how they did it, exposing the systems flaws and generating buzz both online and in the tech community. The airline, instead of punishing them, decided to reward them with free flights for life for revealing the vulnerability and contributing to improved security.
At UFA Temple, something happens that immediately captivates you. Two kneeling figures bear the weight of centuries of rejection.

Measuring over 70 m tall, its internal drainage system prevents erosion. It took nearly 90 years to complete and still stands as a stunning feat of ancient engineering that continues to amaze visitors.
There's something almost no one notices during a game, but when you discover it, you're blown away. Sports cameramen, especially in basketball, follow the action at breakneck speed, anticipating plays in seconds as if they were right there in the game. It's not just about moving the camera. It's about reading the rhythm, positioning yourself perfectly, and reacting without hesitation.
There are robots taking precision to another level, and they come from Yasawa. Inspired by samurai, these systems use AI to learn movements, anticipate actions, and improve in real time. They analyze data instantly and adjust their strategy as if they had firstirhand experience. They are used in simulations and advanced technological development. Seeing them in action is intense and demonstrates that artificial intelligence no longer just executes. It also learns and adapts.
Walking two dogs with one hand sounds complicated until you see how the Wigy Dual Doggy works. This retractable leash changed everything with its 360° swivel system where both lines extend from a central rotating shaft preventing them from tangling even if the dogs keep crossing paths. But what's truly remarkable is its independent control.
Each leash has its own color-coded brake button, so you decide who goes forward and who stops. It can handle larger dogs and makes walks much smoother. You stop struggling with the leashes and simply enjoy the moment.
In northeastern India, there's a tradition that immediately captures your attention. Wancho and Noctday women dye their teeth black. This ritual marks important milestones and is performed using natural mixtures like charcoal and plants that help protect the enamel.
They also believe it acts as a barrier against negative energies. Today, this practice continues combining identity, protection, and beauty in a single smile that shatters any preconceived notions of normality.
There's an aircraft that could change how energy is transported around the world. And it sounds incredible. We're talking about Radia's WindrRunner. This flying giant aims to transport wind turbine blades over 100 m in diameter with a capacity up to 10 times greater than a Boeing 777.
It can land on dirt runways and fly directly to remote areas. If it takes off as planned, it won't just move enormous pieces. It will fundamentally change how energy is generated.
