Your dog isn't just watching your every move—they're judging them, too. According to research by Akiko Takaoka of Kyoto University , dogs are a lot better at reading human behavior than we give them credit for. In fact, they know when you're lying. And worse? They remember it.

The experiment that exposed canine trust issues

In a clever experiment involving 34 eager and unsuspecting pups, Takaoka and her team put canine social smarts to the test. The setup was simple: most dogs will follow a human’s point to find food. So, first, researchers pointed to containers with treats. The dogs eagerly trotted over, rewarded with snacks and tail wags.

"Dogs can tell when you're lying. And they don’t like it one bit."

Then came the twist. Researchers pointed again—but this time, the containers were empty. The dogs arrived, hopeful, only to find nothing inside. A harmless prank, perhaps. But the dogs didn’t see it that way.

Once lied to, twice shy

The final round revealed just how deeply dogs care about honesty. Researchers again pointed to containers, this time with real treats. But the dogs didn’t budge. Every single one of the 34 refused to fall for it again.

"Not a single one approached the container in the third round."

According to Takaoka, the results show just how tuned-in dogs are to human trustworthiness. “Dogs have more sophisticated social intelligence than we thought. This social intelligence evolved selectively in their long life history with humans,” she explained in an interview with the BBC . Even she was surprised by how quickly dogs “devalued the reliability of a human.”

"They remembered the earlier deceit—and acted on it."

Our pets, the furry philosophers

So what does this mean for all of us with furry friends? It’s a reminder that our dogs are more than just pets—they're perceptive partners, quietly observing and emotionally reacting to the way we interact with them. They’re not only capable of joy and affection but also of skepticism and disappointment.

Next time you play a sneaky game of “fake the throw,” remember—your dog might not be so quick to forgive. Trust is a two-way street, even with a tail on the other end.

Scientists extracted a Pink Floyd song from brainwaves and it’s haunting

The concept of reading thoughts once belonged to the realm of science fiction, but breakthroughs in neural decoding are turning it into reality. This technology, which interprets brain activity into meaningful signals, has already allowed scientists to reconstruct words and images from brainwaves. Now, researchers at the University of California, Berkeley have taken it a step further. In August 2023, they managed to recreate a Pink Floyd song purely from brain activity, a discovery published in PLOS Biology that offers new insight into how the brain processes music.

A team led by Robert Knight and Ludovic Bellier conducted the study on 29 epilepsy patients at Albany Medical Center in New York who were undergoing brain surgery. While the patients were in the operating room, they listened to "Another Brick in the Wall, Part 1" by Pink Floyd. Electrodes placed directly on their brains recorded the electrical signals produced as they processed the song. Using artificial intelligence, Bellier later reconstructed the track based entirely on these neural recordings. The final result was hauntingly distorted yet unmistakably recognizable. "It sounds a bit like they’re speaking underwater, but it’s our first shot at this," Knight told The Guardian.

Why you look great in the mirror but awful in photos, according to science

The morning after a wild night of partying, the biggest fear often isn't regretting what you said, but how you'll look in your friends' tagged photos. Even if you left the house feeling like a 10, those awkward group selfies can make you feel like a 5, making you wonder, "Why do I look different in pictures?"

This strange phenomenon, amplified by selfies, is making people question their own mirrors. Are pictures the "real" you or is it your reflection? Have mirrors been lying to us this whole time??

They faked a black hole in a lab—and what it “leaked” has scientists freaking out

Black holes are the universe’s ultimate mystery box—nothing gets out, and no one really knows what’s inside. But now, a group of scientists may have just pulled off something incredible: they built a black hole replica right here on Earth.

And not just for fun. This experiment could help explain one of the biggest cosmic puzzles of our time—Hawking radiation, the theory that black holes slowly lose energy by giving off faint particles at their edges.

5 body language habits that make you instantly more charming

The sayings, “Actions speak louder than words,” and “It’s not what you say, but how you say it,” are popular adages for good reason. Our silent body language speaks volumes, but we may not always be aware of what we’re saying with it. The way we hold ourselves, our gestures, and even how we make eye contact can make a huge difference in how people perceive us.

And that perception makes a difference. People form a first impression within seconds, and some research shows that traits like trustworthiness start to be judged within a tenth of a second of meeting someone.

Drones are firing seed pods to plant forests — and it’s actually working

Technology is the single greatest contributor to climate change but it may also soon be used to offset the damage we’ve done to our planet since the Industrial Age began. In September 2018, a project in Myanmar used drones to fire “seed missiles” into remote areas of the country where trees were not growing. Less than a year later, thousands of those seed missiles have sprouted into 20-inch mangrove saplings that could literally be a case study in how technology can be used to innovate our way out of the climate change crisis.

“We now have a case confirmed of what species we can plant and in what conditions,” Irina Fedorenko, co-founder of Biocarbon Engineering, told Fast Company. “We are now ready to scale up our planting and replicate this success.”
