This Unusual Optical Illusion Could Reveal Insights into Animal Thought Processes

A recent study reveals that certain optical illusions can deceive some animals, though not all. This emerging research may offer fresh insights into how perception influences survival and evolution in different species.

The optical illusion examined in this research is known as the Ebbinghaus illusion, where two identical circles appear different in size because one is encircled by a larger circle, while the other is surrounded by a smaller one.

When observing the illusion overall, the outer circle misleads our brain into perceiving the inner circle as a different size. However, focusing solely on the inner circles reveals that they are indeed the same.

Our susceptibility to this illusion hinges on how our brains interpret visual information, whether as a cohesive whole or detailed parts.

To investigate how various animals perceive their surroundings, scientists at the University of Vienna in Austria recreated the Ebbinghaus illusion using bait, arranging circles of differing sizes around a central bait area.

Next, they observed the responses of two fish species: guppies (Poecilia reticulata) and ring doves (Streptopelia risoria).

The findings indicated that guppies are reliably deceived by optical illusions, similar to humans; they often preferred to consume fish flakes within a smaller circle, perceiving them as larger food items.

In contrast, ring doves exhibited varying responses; some birds chose millet seeds surrounded by a smaller circle, while others opted for those within a larger circle.

The researchers concluded that these choices highlight how each species is uniquely equipped to interact with its environment and tackle its challenges.

For instance, guppies inhabit shallow tropical rivers, where they encounter flickering lights, thick vegetation, swift predators, and numerous other guppies.

Researchers believe that for guppies, quick judgment of which fish are safe in a visually cluttered environment is crucial for survival. Thus, making rapid decisions could be advantageous.

Conversely, wood pigeons spend their lives on the ground, foraging for seeds. For them, noticing fine details could be more beneficial than analyzing the broader scene.

Nevertheless, scientists have observed that some pigeons react as if they are misled by a hallucination, indicating variability within species, much like humans.

Overall, the team concluded that optical illusions can provide a valuable lens through which to explore the diverse perceptions across species.

The Illusion of God: Exploring the Pope’s Popularity as a Deepfake Image in the Age of Artificial Intelligence

For Pope, it was the wrong kind of Madonna.

The pop legend behind the ’80s anthem “Like a Prayer” has been at the center of controversy in recent weeks after posting a deepfake image of the Pope hugging her on social media. This further fanned the flames of an already heated debate over the creation of AI art, in which Pope Francis plays a symbolic and unwilling role.

Catholic Church leaders are accustomed to being subject to AI fabrications. One of the defining images of the AI boom was Francis wearing a Balenciaga down jacket. The stunningly realistic photo went viral last March and was seen by millions of people. But Francis didn’t understand the funny side. In January, he referenced the Balenciaga image in a speech on AI and warned about the impact of deepfakes.

“Fake news…Today, ‘deepfakes’ – the creation and dissemination of images that appear completely plausible but false – can be used. I have been the subject of this as well.” he said.

Other deepfakes include Francis wearing a pride flag and holding an umbrella on the beach. Like the Balenciaga images, these were created by the Midjourney AI tool.

Rick Dick, the Italian digital artist who created the image of Madonna, told the Guardian that he did not intend to offend with the photo of Frances putting his arm around Madonna’s waist and hugging her. Another image on Rick Dick’s Instagram page seamlessly merges a photo of the Pope’s face with that of Luigi Mangione, the man accused of killing UnitedHealthcare CEO Brian Thompson. They are more likely to be offended.

Rickdick said Mangione’s image was intended to satirize the American obsession with Mangione being “elevated into a god-like figure” online.

“My goal is to make people think and, if possible, smile,” said the artist, who goes by the stage name Rick Dick, but declined to give his full name.

He said that memes (viral images that are endlessly tweaked and reused online) are our “new visual culture, fascinated by their ability to convey deep ideas quickly.”

Experts say the Pope is a clear target for deepfakes because of the vast digital “footprint” of videos, images, and audio recordings associated with him. AI models are trained on the open internet, which is filled with content featuring prominent public figures, from politicians to celebrities to religious leaders.

Sam Stockwell, a researcher at Britain’s Alan Turing Institute, said: “The Pope is frequently featured in public life and there are vast amounts of photos, videos, and audio clips of him on the open web.” said.

“Because AI models are often trained indiscriminately on such data, these models are more sensitive to the facial features and facial features of individuals like the Pope than models with less large digital footprints. It makes it much easier to reproduce the similarities.”

Rick Dick said the AI model he used to create the photo of Francis that was posted to his Instagram account and then reposted by Madonna was created on a paid platform called Krea.ai by the pope and the pop star. It is said that the robot was trained specifically for images. However, realistic photos of Francis can also be easily created using freely accessible models such as Stable Diffusion, which allows users to place Francis on a bicycle or on a soccer field with a few simple prompts.

Stockwell added that there is also an obvious appeal to juxtaposing powerful figures with unusual or embarrassing situations, which is a fundamental element of satire.

“He is associated with strict rules and traditions, so some people want to deepfake him in unusual situations compared to his background,” he said.

Adding AI to the satirical mix will likely lead to more deepfakes from the Pope.

“I like to use celebrities, objects, fashion, and events to mix the absurd and the unconventional to provoke thought,” said Rick Dick. “It’s like working on a never-ending puzzle, always looking for new creative connections. The Pope is one of my favorite subjects to work on.”

Could space and time be an illusion of entanglement? Clues may be found in black holes

We tend to think of space-time as the underlying structure of the universe, but whether it’s truly fundamental, or whether it arises from something much deeper, is a question that keeps physicists up at night. “It’s not a philosophical question to debate over a beer,” physicists say. Marika Taylor “This is something that actually gets built into the calculations that people make,” say researchers from the University of Birmingham in the UK.

A great place to start is quantum mechanics, which describes the behavior of elementary particles. One of the core tenets of this notoriously counterintuitive theory is that connections between particles can transcend our usual concepts of space and time. This happens through a phenomenon called quantum entanglement, in which particles can affect each other’s properties even when they’re half a universe apart.

Cosmologists now generally accept that quantum entanglement is intimately connected to the emergence of space. If we know the degree of quantum entanglement between two quantum particles, we can derive the distance between them. When we do this for a network of many particles, a geometry begins to form from which we can call space emerge. In other words, space may emerge from quantum entanglement.

Entanglement and space-time

Furthermore, advances in string theory, a candidate theory of everything, suggest that what happens in the universe can be explained entirely by data held at the exterior, or boundary, of that space — a phenomenon known as holographic duality. Combine this with quantum entanglement and you can build a universe that boasts a spatial fabric of distance and geometry.

Experience the Tonight’s Moon Illusion: A Guide to Witnessing the Breathtaking “Moon Shadow”

The early crescent phase of the moon following the new moon is well located in the early spring evening sky. From February to March, the spring crescent moon looks very beautiful in the evening glow.

If you have binoculars or a small telescope, there are some things to keep in mind. Known as the clair-obscure effect, or trick of the light, this effect causes recognizable shapes to appear within a jumbled area of ​​moonlight and shadow. Two popular examples are known as Moons X and V. These occur simultaneously at different locations along the moon’s terminator (the line that separates night and day).

We spot them in the daytime sky around 12:40 a.m. on February 17th and again at 2:20 p.m. on March 17th. The effect lasts only a few hours.

Another striking Clair Obscure effect is the Jeweled Handle. This occurs a few days after the waxing moon, when the crooked peaks of the Montes Jura (Jura Mountains) are illuminated at dawn.

Its unique arc appears to extend into the lunar night. This can be seen with just a keen eye, but is best seen with optical aids. The jeweled handle is best observed during daylight hours on February 19 at 3:50 p.m.

If the evening of March 13 is clear, the waxing moon will appear near bright Jupiter. If the skies are clear and you can see it with just your eyes, it’s a spectacular sight.

Speaking of eyes, if you have a small telescope, look at the southern part of the moon in a few days, on March 18th. Just before 8 p.m., the oval exterior of Clavius, the large crater, is mostly dark and shrouded in shadow.

Two exceptions are the raised crater rims that are illuminated within them. These form another perspective effect known as the Eye of Clavius.
