12 quirky inventions people once swore would change the world

Arvyn Braich — Fri, 08 May 2026 11:24:58 +0000

Some ideas seem like they’re going to be so impressive. They show up with fireworks & headlines, but a few years later, they disappear entirely. History is packed with “next big things” that went nowhere.

Here are twelve inventions that people genuinely believed would change the world, yet they failed. Which do you wish had been successful?

Segway personal transporter

During the early 2000s, people thought that the Segway would be the ride that would change cities forever. They pictured streets full of commuters gliding around on them. Reality said something different.

Not only did they cost around five grand, but a string of accidents made people go off these “revolutionary” devices rather quickly. They stuck to being used as tourist rentals & in warehouses.

Google Glass smart glasses

You’d be forgiven for thinking that Google Glass would change the world, since they really did look like something out of a sci-fi movie. They were supposed to change the way we interacted with practically everything.

Unfortunately, nobody likes being filmed without warning, and the devices themselves were rather expensive. It didn’t take long for Google to cancel the glasses.

Sinclair C5 electric trike

British inventor Clive Sinclair revealed the Sinclair C5 electric trike in 1985. It ran around 15 miles an hour & he claimed that it would revolutionize the way that people travel.

But the future had something different to say. It didn’t fare well in rainy weather and couldn’t even take on hills successfully. The factory producing the trike shut down the same year that it launched.

Moller Skycar M400

Essentially, the Moller Skycar M400 was a red flying car that looked like it came from The Jetsons. Its creator, Paul Moller, promised that it would make traffic jams a thing of the past, since it allowed people to take off vertically & have a fast flight. It didn’t.

The Skycar never made a free, manned flight, so the dream of a flying commute failed to clear the runway.

Juicero press

Who needs a Wi-Fi-connected juicer? According to the makers of the $699 Juicero press, everybody. It was supposed to completely change the way people drank juice and enable them to have a healthier diet. But it was a flop.

It was far easier & faster to squeeze the special juice packs by hand, leading to sales of the Juicero press collapsing. It shut down in 2017.

The :CueCat barcode reader

Around 2000, the :CueCat barcode reader was launched, and millions of people received a free copy of it in the mail. It allowed people to scan barcodes from magazines & go straight to the website, a little like QR codes.

However, typing the URL manually was much easier. The reader never managed to change the way that we go online in the way that the company expected.

DigiScents iSmell

Smell-o-vision was almost a reality. The DigiScents iSmell was a plug-in device that would send smells through a computer, allowing you to literally “smell” the games you were playing or websites you were on.

It would’ve changed internet browsing by making it a 4D experience. However, investors soon realized that nobody wanted to download perfume files or buy the hardware. The iSmell failed before it even got out of the gate.

3D TVs for the living room

There was a time when practically every electronic store pushed 3D TVs, particularly after 2010’s Avatar mania. These TVs were supposed to bring movie-theater magic to your living room. The key phrase there being, “supposed to.”

The glasses were too annoying to use & the cost of upgrading to a 3D TV just didn’t seem worth it. No wonder Sony & LG dropped 3D completely in 2017.

OLPC XO

The idea of the OLPC XO was great. It involved giving every child in developing countries a special $100 laptop to help them with their education. In theory, it would minimize the digital gap between developing & developed countries.

Some countries bought small batches. However, the project never scaled the way it was intended to & failed to close the digital gap.

Solar Roadways

People genuinely believed roads could power the world. Solar Roadways built panels with LEDs & sensors that were supposed to produce clean energy far more efficiently than other technology of the time. Unfortunately, it didn’t work out that way.

The tiles were fragile and hard to clean, for starters, while maintenance bills were high. Most of the panels couldn’t produce enough energy to be reliable.

Segmented sleep pods

Segmented sleep pods promised users that they could get 20-minute naps at work that would leave them feeling fully recharged. Advocates of the device claimed they’d help the world become more productive, as workers could put in more hours at the office.

But they never went mainstream. The cost & space of the pods were enough to turn people off, and most places stuck with coffee instead.

Telautograph

During the time before faxes & email, the telautograph was supposed to be the next best thing. Inventor Elisha Gray patented it in 1888 with the claim that you could send your handwriting over wires in real time using it. You could sign contracts & send notes from miles away, without using a typewriter, completely changing communication.

At least, in theory. The telautograph was slow & expensive. The telephone was a lot faster to use, not to mention cheaper.

10 foods loved by U.S. Presidents

Radha Perera — Mon, 04 May 2026 14:36:34 +0000

The White House menu hasn’t always been caviar & champagne. Nope, a lot of presidents had favorite foods that were surprisingly simple…or sometimes just odd. Here are ten foods that U.S. presidents loved, according to history books. Which of these would you pick to cook for dinner tonight?

Hoecakes with honey at Washington’s breakfast table

George Washington enjoyed starting his day with hoecakes, which are essentially griddled cornmeal cakes. He always had them drenched in honey. In fact, his step-granddaughter, Nelly Custis Lewis, left behind instructions describing how he would make sure the batter went right onto the griddle & flipped once before serving it with butter.

Jefferson’s macaroni, parmesan, and a pasta press

Thomas Jefferson wasn’t shy about experimenting in the kitchen. He actually drew diagrams of a macaroni press & wrote notes on the process of how to make it. This was based on what he saw in Naples. Back in America, he often imported Parmesan and recorded recipes for macaroni & cheese.

Lincoln’s fondness for gingerbread

Once upon a time, Abraham Lincoln joked on the campaign trail about how he loved gingerbread. He also confessed that he very rarely got much of it as a kid, claiming, “I loved it better than any other man, and got less of it.” Still, it seems that gingerbread was a treat he never truly forgot.

Taft’s “possum and ’taters” banquet in Atlanta

In 1909, Atlanta threw William Howard Taft a banquet. However, it wasn’t your regular banquet, since the star of the meal was roast opossum with sweet potatoes, instead of steak or duck. Hardly something you’ll find on most plates. Even so, Taft apparently loved the meal, and this wasn’t his first time eating it, either.

FDR’s hot-dog picnic for a royal visit

You’d expect Britain’s King George VI & Queen Elizabeth to eat fancy roasts or delicate pastries when they showed up at Hyde Park in 1939. But no. Instead, Franklin Roosevelt served them hot dogs on paper plates & told them to dig in. The royals were game enough to try them.

Eisenhower’s own vegetable soup

Sure, Dwight Eisenhower was a general who later became president. Yet he also liked cooking. He had a vegetable soup recipe, where he insisted on using a beef bone for flavor & allowed it to bubble away for hours. You’d hardly expect this from a guy who commanded armies.

Kennedy’s New England fish chowder

John F. Kennedy’s love for fish chowder wasn’t a secret in his family, and he had a preference for the creamy, rich kind. It had to be packed with haddock & salt pork, as well as potatoes. For him, this was pure New England comfort food. Kennedy even sent a recipe to a young fan who asked what he liked to eat.

LBJ’s Pedernales River chili

Lyndon Johnson was president with strong opinions about chili. He wanted no beans, ever, and his recipe, known as “Pedernales River Chili,” was heavy on beef, onions, peppers & spice. He liked it so much that White House staff handed it out. However, it was hardly a mild chili. Anyone eating it would have to be prepared to sweat through a bowl.

Nixon’s cottage cheese and pineapple

Honestly, cottage cheese sounds like an odd choice for presidential food, but that’s Richard Nixon for you. Sometimes he put pineapple on top, sometimes he’d put ketchup. His last meal before resigning in 1974 was actually a simple plate of cottage cheese & pineapple, along with a glass of milk.

Reagan’s jelly beans

Ronald Reagan kept jars of jelly beans within reach almost everywhere he went, including his desk & Air Force One. He even had them during cabinet meetings. Originally, he ate them to quit smoking back when he was California’s governor…and then never stopped. The company Jelly Belly even made special colored mixes for the White House.

6 myths and facts about pirates

Arvyn Braich — Fri, 01 May 2026 16:36:02 +0000

Most people imagine eye patches & parrots whenever they think of pirates, and a whole lot of “arrr.” Unfortunately, films & books did a great job of mixing fact with fiction. The truth about them is a lot stranger than the stories, so here are six myths & facts about pirates. Which of these myths fooled you the longest?

Featured Image Credit: Shutterstock.

Pirate speech sounded like “arrr”

Everyone knows that classic pirate growl. But it turns out that it’s not real, as it came from a 1950 film featuring the actor Robert Newton, who played Long John Silver with a West Country accent. Audiences loved it. So much so that everyone started thinking it was how pirates talked, when really, they spoke in whatever accents they grew up with, like a London or American one.

Every pirate flew the skull-and-crossbones

Not every ship had the same black flag with bones & skulls. Some had red flags, while others painted hourglasses or bleeding hearts, mostly because being a pirate wasn’t a brand. The goal of a flag was to scare the target into giving up quickly. In fact, the famous Jolly Roger flag was just one of many designs at sea, although it’s probably the most remembered one.

Piracy only happened in the Caribbean

Piracy didn’t simply involve palm trees & rum. Actually, the Indian Ocean was one of the most popular places for pirates, who would strike along East Africa & India. Even Madagascar had bases for crews who sailed out to rob trade routes. Sure, the Caribbean was busy, but piracy stretched across almost every ocean & wasn’t confined to this one place.

Pirate ships had no rules or structure

Many people imagine pirates as being lawless crews on board a ship. But records show the opposite. Usually, crews wrote down articles that worked like contracts, covering pay & discipline, as well as injury insurance. They also elected captains and had quartermasters to balance their power, meaning that even these rogues ran things with surprising organization.

Pirates made people walk the plank

One of the most famous pirate myths is that they made people walk the plank as punishment. Sadly, it’s not real, as the idea only really appeared in the late 1700s. This was long after the so-called Golden Age of piracy. It’s thanks to writers in the 1800s who kept using it in adventure stories that we have this myth. Actual pirate punishments were usually quicker & more brutal.

Pirates drew “X marks the spot” maps

Treasure maps with giant Xs are a product of fiction that started with Robert Louis Stevenson’s Treasure Island. Scholars haven’t been able to find any authentic pirate maps that have these markings. That’s mostly because pirate crews very rarely buried their loot. And even if they did, they would hardly leave behind handy diagrams for anyone to follow.

Famous historical figures connected by blood or family

Arvyn Braich — Sun, 26 Apr 2026 12:34:55 +0000

Not all famous people from history crossed paths in books. Nope, a few of them were literally related, with blood ties & family links connecting people from all walks of life. Here are eight famous historical figures who were weirdly connected. Which family tie here do you think is the strangest one?

Featured Image Credit: Shutterstock.

Eleanor Roosevelt was Theodore Roosevelt’s niece

Sure, Eleanor Roosevelt was a First Lady, but she also grew up calling Theodore Roosevelt “Uncle Teddy.” Her dad was Theodore’s younger brother, Elliott. Eleanor did lose both of her parents rather young, and when she married Franklin Roosevelt in 1905, it was Uncle Teddy himself who gave her away at the ceremony.

Napoleon III was Napoleon I’s nephew

France used to be a country that kept things in the family. Napoleon III, born Charles-Louis Napoléon Bonaparte, was the son of Louis Bonaparte, who was Napoleon I’s brother. He spent years of his life as an exile, even escaping prison in 1846 & eventually, he took power as President in 1848, then as Emperor.

Nicholas II and George V were first cousins

The Russian Tsar & the British King were first cousins, as their mothers were sisters. They were daughters of King Christian IX of Denmark, making Nicholas II and George V family. In fact, the resemblance was so strong that people joked about it when they saw photos of them side by side. They often wore the same uniforms and had the same beard style, just to prove the point.

Franklin Pierce was related to Barbara Bush

Franklin Pierce is often remembered as one of the quieter presidents & he actually shares an ancestor with Barbara Bush. Both come from Thomas Pierce, who settled in Massachusetts back in the 1600s. As a result, Barbara Bush & her presidential family, husband George H. W. Bush & son George W., are distant cousins of Franklin.

Princess Diana was related to Winston Churchill

Sure, Diana Spencer married into history. But she was already connected to it. She and Winston Churchill both came from the Spencer-Churchill line, which is an aristocratic family that had been part of Britain’s upper ranks for centuries. Her father was the 8th Earl Spencer. He was part of the same family tree that also produced Churchill.

Ulysses S. Grant and Franklin D. Roosevelt shared a common ancestor

It’s weird how tangled Presidential family trees can get, and one good example is how Ulysses S. Grant and Franklin D. Roosevelt were cousins, far removed. This was through Jonathan Delano, a settler in early New England. In fact, the Delano line kept branching for generations until it connected these two men, each of whom was rather important to American history.

George Washington was related to Robert E. Lee

That’s not all for American historical figures. While Robert E. Lee didn’t have Washington’s blood running through his veins, he still ended up in the extended Washington family. George Washington Parke Custis was the president’s step-grandson & Lee’s father-in-law. Lee also lived at Arlington House, which Custis had built in memory of America’s first president.

Barack Obama and George W. Bush are distant cousins

Barack Obama’s family traces back to colonial Massachusetts and has a Bush connection. It turns out Obama and George W. Bush are 11th cousins, with a shared ancestor in Samuel Hinckley of Cape Cod. He lived in the 1600s. Of course, that’s not exactly close family, but enough to land them on the same family tree.

8 key facts about body language

Radha Perera — Wed, 22 Apr 2026 20:13:10 +0000

We usually move around without thinking about how much our bodies are “saying.” At least, most of the time. But scientists have actually tracked some pretty unusual patterns & the results are more interesting than a simple smile-or-frown. Here are eight research-backed facts that might surprise you (see the end). Do you know any other weird body language facts?

Featured Image Credit: Shutterstock.

People mimic posture and mannerisms

You may have noticed that when someone crosses their legs, you do the same. That’s not just a coincidence. In experiments, people automatically mirrored the small body language habits of their partners, like touching their face or tapping a foot. They’re not usually aware of it. It even happens in casual conversations where nobody was trying to copy anyone.

Blinks sync at the same moments during shared viewing

People tend to blink at the same time when they sit down to watch the same short video. In one lab test, 14 participants blinked in the same moment when the story naturally paused. It’s almost like their brains were taking a break together. Even when the movie didn’t have breaks, people still blinked at the same time.

Pupils dilate during problem-solving

During the 1960s, researchers noticed that people’s pupils grew bigger while solving math problems. Later studies kept finding the same thing. This showed that the eye change wasn’t random. When someone tried working out multiplication in their head, their eyes started dilating, and when they stopped, it faded. Effort makes your eyes shift shape. Who knew?

A “Duchenne” smile

Not every smile is built the same. There’s a grin called a “Duchenne” smile that uses both the cheek muscles & a little squeeze around the eyes, which people show when they’re reacting to something genuinely amusing. Scientists conducted research and found that electrodes placed on the face picked up that difference clearly.

Personal distance zones have measured ranges

Anthropologist Edward T. Hall once used a tape measure to literally track how close people stood in everyday life. It’s different across different countries. In America, the patterns were pretty consistent, as under 18 inches was “intimate,” 1.5–4 feet was “personal,” & 4–12 feet was “social.” Anything beyond that was “public.”

Handshakes transfer skin-bound molecules

Two strangers shook hands in one experiment & something unexpected happened. Chemicals from one person ended up on the other’s glove, including things like squalene & fatty acids. Cameras also caught people touching their noses more afterward. Airflow sensors picked up that they were actually sniffing, almost like they were checking the sample.

Lie judgments hover around 54% accuracy

One study involved volunteers having to guess the difference between truth vs. lies. The grand total average was about 54% correct & that’s only slightly better than flipping a coin. It didn’t matter whether they were watching faces or listening to voices. Their accuracy kept landing right around the same number.

Foot pointing often shifts toward chosen actions

Researchers have noticed something funny about feet. They tend to “decide” before the rest of you does. Experiments showed that people’s feet angled toward the thing they were going to pick, like an object on a table or a way out of the room. The body leaned in first & words came later.

8 fascinating facts about insects

Radha Perera — Sat, 18 Apr 2026 08:28:48 +0000

Insects are everywhere. Surprisingly enough, they have some incredible tricks up their sleeves, including chemical sprays hotter than your morning coffee. These creatures are full of surprises. Here are eight remarkable facts about insects, all backed by science (see the end). Which of these bugs surprised you the most?

Featured Image Credit: Shutterstock.

Fire ants link bodies to build waterproof rafts

Fire ants quite literally hold their legs & jaws together with other ants to stay above water. They do this when floods come along. These creatures snap together like LEGO pieces, with enough trapped air to keep the whole colony afloat for days. That’s pretty amazing teamwork. And especially for bugs that usually just bite.

Periodical cicadas run on prime-number schedules

You wouldn’t think that cicadas care about math, but they do. Some cicadas stay underground for thirteen years, or sometimes seventeen. They’ll then crawl up to the surface. Scientists say the odd-number cycles help them avoid predators’ rhythms. And honestly, waiting that long for a few weeks of flying sounds rather wonderful for an insect.

Honeybees map directions with a dance

You might’ve seen bees doing figure-eight moves inside their hives. That’s not just random buzzing around. They’re creating a map to tell other bees where the food is compared to the sun. The wider the angle of the dance, the farther away it is. Essentially, they’re showing off their bee GPS, just without Wi-Fi.

A tiger moth can jam a bat’s echolocation

Tiger moths have the remarkable ability to click away at high speed. This throws off a bat’s echolocation completely. In fact, it’s so strong that the bat’s attack often fails because it simply can’t get a read on where the moth is. Scientists muted the moths during an experiment & the bats started catching them again.

Glasswing butterfly wings cut glare with nano-pillars

Glasswing butterflies look almost invisible in flight, and that’s thanks to their wings that act like natural anti-reflective glass. They have tiny, uneven pillars on the wing surface. These pillars scatter light in all directions, which is quite different from smooth glass. Their wings allow you to see straight through without any glare.

Treehoppers talk by vibrating plants

Instead of chirping like crickets, treehoppers prefer to send messages through plant stems. They create low vibrations that go along the leaves & stalks. Other insects pick it up with their legs, meaning that they’re quite literally talking through plants. How amazing is that?

Cockroaches have an ultra-fast escape circuit

Anyone who’s ever tried to sneak up on a roach will know it’s nearly impossible. This is because they have little hairs on their back end that sense the tiniest puffs of air, sending a lightning-fast signal straight to their legs. They’ve already picked a direction & bolted within a fraction of a second. No wonder they’re so hard to catch.

Dragonflies can see in almost every direction

A dragonfly’s eyes cover nearly its whole head. As such, it can spot movement from the front, back & sides without needing to twist around. But that’s not all. Each compound eye holds around 30,000 tiny lenses, which gives them quite an edge. They notice changes almost instantly from any prey they’re chasing in the air.

7 notable facts about ancient pyramids

Hasthi Wand — Mon, 13 Apr 2026 08:34:07 +0000

Pyramids have been around for thousands of years. Yet there are still details about them that most people never hear, including some bizarre measurements & purposes. Here are seven interesting facts about ancient pyramids that are backed by science. What other cool things do you know about them?

Featured Image Credit: Shutterstock.

The Great Pyramid’s north alignment

Everyone knows how great the Great Pyramid of Egypt is. But there’s so much more to it than its size. The Great Pyramid’s sides miss true north by just a hair, less than three arcminutes. Evidence suggests builders watched a pair of circumpolar stars line up to get that accuracy. That’s right. No compasses, just star-spotting.

Muon scans mapped a hidden void and a separate corridor

When physicists aimed cosmic-ray detectors at Khufu’s pyramid, they caught something unexpected. They saw a long, empty cavity that they called the “Big Void.” It stretches over 100 feet above the Grand Gallery. Years later, the same method turned up a smaller passage tucked behind chevron blocks on the north face. How incredible is that?

Meroë’s royal cemeteries contain over two hundred pyramids

Egypt isn’t the only place with pyramids. In the south of Sudan, the site of Meroë is like a much more crowded version of the Egyptian ones, with over two hundred pyramids in its cemeteries. They’re smaller & much steeper than Giza’s. They were built roughly 800 BCE & 350 CE, and standing there, you can see the pyramids in all their greatness.

A handclap at Kukulkán’s pyramid

Anyone who visits Chichén Itzá should try this. Clap once at the base of Kukulkán’s pyramid, and instead of a plain echo, you hear a sharp chirp that drops in pitch. Studies show the stone steps scatter sound waves in a way that sounds like a birdcall. The effect works best if you’re facing the staircase head-on.

Mayan pyramids were used as observatories

Some Mayan sites have pyramids that aren’t just places for ceremonies. They were built with angles that matched up with the movements of the sun & stars. This includes the Pyramid of the Magician at Uxmal, which has a layout that helped priests follow solar cycles & seasonal changes. That kind of tracking was important for their farming schedule.

The Pyramid of the Moon held sacrificial burials

At Teotihuacan’s Pyramid of the Moon, archeologists uncovered some grim things. They found burials of people with tied hands next to animals like jaguars & eagles. They also found obsidian blades and other offerings placed with them. But that’s not all. These were sealed into the structure during different construction stages, meaning ritual sacrifice was built into the process.

Nubian pyramids often included decorated chapels

The cemeteries of ancient Nubia include pyramids with chapels in the front. These weren’t empty spaces, as they had walls with colorful reliefs & inscriptions that described offerings to the dead. Families could visit and leave food or ritual items there. It helps them keep a connection with the buried.

10 remarkable facts about the moon

Hasthi Wand — Wed, 08 Apr 2026 14:13:07 +0000

Everybody’s seen the Moon hanging up there. But it’s a lot stranger than a simple, pale ball of rock. The more scientists poke at it, the weirder it gets, and here are ten remarkable facts about the Moon, backed by science (see the end). Which one of these surprises you the most?

Featured Image Credit: Shutterstock.

The Moon’s core is shaped like Earth’s, but much smaller

To start with, the Moon isn’t simply a solid hunk of rock. It has a tiny inner core that’s made of dense iron-like material. It’s only a few hundred miles wide & is wrapped in a liquid layer. Essentially, you can think about it as being like Earth’s core. But it’s shrunk down by quite a bit. How cool is that?

Some lunar spots are colder than Pluto

Most people know that Pluto’s freezing. But it turns out that parts of the Moon are even colder, as the bottoms of certain lunar craters barely creep above minus 390°F. That’s colder than some parts of deep space. These holes trap ice, and they don’t get a single ray of sunlight. Ever.

The Moon has a 500,000-mile-long sodium tail

The Moon has its own faint orange tail made of sodium atoms, which stretches about half a million miles into space. We can’t see it with our eyes. However, astronomers have cameras that catch the glow around the same time of the new moon. It’s a pretty incredible sight to behold.

Moonquakes can last nearly an hour

You probably know that the Moon doesn’t have earthquakes because, well, it’s not Earth. It has moonquakes instead. The seismometers on Apollo spacecraft have measured these quakes, and some of have gone on for almost an hour. This is because the Moon’s dry crust doesn’t dampen vibrations like Earth’s. As such, the tremors just bounce around for a long time.

Gravity on the Moon is lumpy and weird

Gravity works differently on different parts of the Moon. That means that spacecraft flying over certain spots will be tugged down harder than expected, and those spots are called “mascons.” This is short for mass concentrations. Essentially, they’re hidden gravity potholes & they came from giant asteroid impacts. These left behind heavy, dense layers underground.

The far side is built like a fortress

The far side of the Moon is the one we never see from Earth. It has a crust that’s much thicker than the side we know, and the difference between the two is like the difference between a paper plate & a brick wall. This is one of the main reasons why that side has a lot of rugged mountains, instead of smooth lava plains.

Lava erupted just two billion years ago

Not all Moon lava is as ancient as you might think. In 2020, China’s Chang’e-5 mission scooped up volcanic rock that turned out to be only 1.96 billion years old. That’s practically yesterday from a geologic timeframe. Somehow, the Moon was spewing out lava while dinosaurs were just starting to stir on Earth. That really puts stuff into perspective, doesn’t it?

The Moon once had a magnetic field stronger than Earth’s

The Moon’s surface is relatively quiet today. But long ago, the Moon had a magnetic field that was even stronger than Earth’s. Rocks brought back from Apollo missions show that the field may have been twice as strong as Earth’s. That field lasted for billions of years. It’s quite surprising, given how small the Moon is.

We actually see 59% of the surface

The idea that we only ever see half the Moon isn’t strictly true. The Moon wobbles a little as it orbits, meaning that we get sneak peeks around the edges. Eventually, we see around 59% of the whole lunar surface. It’s not a lot more than half. But it’s enough.

The Moon is slowly moving away from Earth

Scientists have conducted numerous experiments & found out that the Moon isn’t staying put. It drifts a tiny bit farther from Earth each year. It’s not a lot, just over an inch, but it confirms that our lunar neighbor is slowly slipping out of reach. Astronauts left mirrors up on the Moon. On Earth, we bounce lasers off them to measure the distance.

6 interesting things to know about déjà vu

Arvyn Braich — Sat, 04 Apr 2026 13:48:53 +0000

That odd moment when you walk into a place & swear you’ve been there, even though you know you haven’t, isn’t just you. Scientists have studied déjà vu for years through some unusual experiments. It turns out that the brain has a lot of ways of tricking itself. Here are six interesting things scientists have actually found. Which one do you think is the strangest?

Featured Image Credit: Shutterstock.

Electrical stimulation in the temporal lobe can trigger déjà vu

Doctors discovered in neurosurgery labs that zapping certain parts of the brain can set off instant déjà vu. Patients reported feeling as though they were somewhere familiar or even that they had dream-like memories when the electrodes hit the temporal lobe. This is also true in epilepsy cases. Some people feel a sense of déjà vu right before a seizure.

People experience less déjà vu when they’re older

Questionnaires & surveys show déjà vu changes as you age. Teenagers & young adults say they get it a lot, but older adults report it far less, which could be due to stress and fatigue. In fact, one study estimated that around 60% of people have experienced déjà vu at least once. But how often that happens depends quite a lot on your age.

Your brain’s right-side experiences it more

Neurologists compared left vs. right brain stimulation and found something interesting. Déjà vu shows up a lot more often on the right. Patients with epilepsy had electrodes placed in both sides of the temporal lobe, and they reported stronger déjà vu when the right side was activated. That makes sense, since it’s where your hippocampus & rhinal cortex work together.

Some people suffer from “déjà vécu”

Experiencing déjà vu just once can be strange. Now imagine feeling it all the time. For some people, that’s a reality. They feel as though every single thing they do has already happened before. It happened to at least two dementia patients in an experiment, as well as someone with anxiety. Doctors called this “déjà vécu.” It means “already lived.”

Hypnosis can create déjà vu

In 2009, a group of researchers used hypnosis to see how it would affect people’s sense of déjà vu. Participants were told under hypnosis that certain new words would feel familiar later on. When those words actually appeared, the volunteers swore they’d seen them before. But they hadn’t. Clearly, hypnosis can make your brain play all sorts of tricks on you.

Some amnesia patients still experience déjà vu

Even memory loss can’t block déjà vu completely. In one case study, patients with serious amnesia (aka people who couldn’t recall events from just minutes before) still claimed to have feelings of déjà vu. The research found this could be connected to damage in the temporal lobe.

6 interesting facts about the color orange

Arvyn Braich — Mon, 30 Mar 2026 14:06:18 +0000

Orange is more than a simple crayon in the box or a fruit in your fridge. It’s practically everywhere, in science labs & old canvases, even in what you eat for dinner. But there are a few facts about this color that many people don’t know. Here are six interesting facts about the color orange. Which of these surprised you most?

Featured Image Credit: Shutterstock.

Skies turn orange near sunset due to the angles

You’ve probably noticed that the sky glows orange when the sun sinks low. That’s physics at work. Light has to travel farther through air at that angle, so short blue wavelengths scatter away first, and what’s left for your eyes are longer hues like orange & red. Scientists have even recorded this using atmospheric optics research.

Artists used mineral oranges like realgar and crocoite

Before synthetic paints, artists had to use minerals for their palettes. Realgar was one of these. It’s an arsenic sulfide that gave artists a bright orange, but it unfortunately darkens over time. They used crocoite, a lead chromate, for a more intense orange. However, this wasn’t the most stable.

Many stars really are orange to our eyes

Not all stars twinkle white or blue. K-type stars are cooler than our Sun, and they glow with an orange tint, with Arcturus being one of the brightest examples. It has a surface temperature of around 4,300 kelvin (7280°F). Many physicists have studied it & even used it as a calibration point in astronomy. Pretty cool, right?

The color orange didn’t exist in English until the 1500s

It sounds strange, but people in medieval England had no separate word for orange. They simply called the shade “yellow-red.” It was only once the fruit itself started arriving from Asia through trading that people invented the name “orange.” Interestingly, it came through French from the Arabic naranja before eventually sticking in English.

Orange is the hardest color for pilots to ignore

You might’ve noticed that a few things in a cockpit are orange. That’s because when safety engineers tested cockpit controls, they noticed pilots reacted faster to orange warnings than to red or yellow. The color stood out against everything else. As such, they reserved the color for emergency levers & fire handles, as well as other things that need to be noticed quickly.

A rare diamond type is classified as orange

Pure orange diamonds are a major prize among gem collectors. They don’t get their color from added impurities, but instead from unusual twists in the crystal structure itself. Collectors actually have to use spectroscopic scans to confirm the color because orange tones often blend into brown or yellow. “Real” orange stones are so rare that they often head straight to auctions.
