12 real scientific facts that sound completely made up, but aren't

Did you know that placebos work even when people know it's a placebo?

Real life is far stranger than fiction.

And now we have the proof.

A recent thread on r/AskReddit posed the question: "What sounds like pseudoscience, but actually isn't?"

The answers were far more interesting than all the science classes I ever took. Combined.

Let's take a look at some of the strangest scientific facts the good people of the Internet could come up with.

1. Phantom limbs & mirror therapy

Most people have heard of phantom limbs and phantom limb pain, the phenomenon where someone who's lost a limb can still feel pain or other sensations where the missing appendage should be.

But the connection between the brain and the missing limb gets even wilder the more you dig into it.

Did you know that a common treatment for phantom limb pain is something called "mirror" therapy, where a therapist will use a series of mirrors to make it look like the missing limb is still there? This tricks the brain and eases discomfort over time.

Sounds like psuedoscience, but can be extraordinarily effective!

Tip of the cap to u/MonSoleil937 for this one.

2. Ear crystals going haywire

User u/shinjithegale nominates "Benign Paroxysmal Positional Vertigo", or BPPV, a common type of vertigo and dizziness that usually occurs in people over the age of 60.

The weird part? The vertigo is caused by small calcium crystals inside the ear coming loose and flowing into the inner ear.

"Your magical ear crystals are out of sync" definitely sounds fake but is 100% a real, treatable condition.

3. Redheads need more anesthesia than everyone else

This one comes from u/explorerdoraaaaaa — and it can't possibly be true, right?

Wrong.

Red-haired people, who make up only about 2% of the population, may process pain differently from the rest of us and have been shown to often be more tolerant to local anesthetics — they may need up to a 20% stronger dose!

They might also be more sensitive to opioids and less sensitive to shots, needles, and electric shocks.

4. Speaking in a different language can unlock an alternate personality

Where are our personalities stored? In our brains? Our souls?

Despite sounding completely implausible, maybe neither!

If you learn a new language or grow up speaking multiple languages, your personality make be markedly different depending on which language you're speaking.

One study gave people who grew up in Spanish/English bilingual households a personality test in each language and found that their values and personality traits were dramatically different in the respective results.

5. Platypuses exist

That's it. That's the fact, courtesy of u/Steeze-Schralper6968.

The list of true but baffling facts about platypuses goes on and on.

For starters, they're a mammal with a beak that lays eggs, sweats milk, and shoots poison.

If you read about it in a SciFi novel you'd struggle to suspend your disbelief.

6. Duct tape can cure warts for some reason

Most common warts are harmless, but we still don't like having them. That said, because they're not hurting anyone people are hesitant to try invasive or expensive procedures to remove them.

Enter Duct Tape Occlusion Therapy, which is a real thing. Simply apply duct tape to the wart, remove, clean the area, and repeat every couple of days.

Weirdly duct tape therapy isn't just ripping the warts off. There's some evidence that the adhesive used on the tape may cause an immune response in the skin that causes the warts to clear up.

7. The world is brighter for blue-eyed people — and they see better at night

It sounds like psuedoscience, for sure, but eye color isn't purely aesthetic.
People with lighter colored eyes — with less melanin in them — are more sensitive to light.
For blue-eyed people, that may mean they're more sensitive to bright daylight and have better vision at night.

I've always wondered why I can barely walk outside on a cloudy day without sunglasses, and now I know!

8. Eye-Movement Desensitization and Reprocessing

EMDR therapy, nominated in the thread by u/taurussy, sounds like something you'd see a stage hypnotist perform on tipsy audience members.

In reality, it's a powerful therapy for processing trauma.

EMDR involves a patient processing traumatic memories while performing therapist-directed eye movements or otherwise tracking an external stimulus, like a light or an audio track.

The theory is that the process can form new connections between blocked-off and painful memories and more adaptive memories or information, which allows for healing.

9. The placebo effect & open-label placebos

Most of us know about the placebo effect, but it's still almost too unbelievable to be real.

(As a refresher, an example of the placebo effect might be someone with a cold feeling better after taking a "sugar pill" with no medicine in it that they were told would cure them.)

But here's something wild you probably didn't know about placebos:

They can work just as well even when people know they're taking a placebo!

The things our brains can "trick" us into doing are truly incomprehensible.

10. Teratomas

Teratomas sound more like nightmare-fuel than psuedoscience, but they're still worth a mention from u/flugualbinder.

Teratomas are rare kinds of tumors that can grow and contain hair, bones, muscle, and even teeth.

They are real, and you will look up photos of them at your own peril.

11. Pain is all in your head — kind of

Pain is real, and it's valuable information for your body that something is wrong.

But scientists have learned a lot about it, specifically when studying chronic pain. And we know now that our emotions, our beliefs, and other aspects of what happens in our brains plays a big role in how we experience pain.

One study found that Pain Reprocessing Therapy (PRT), basically training the brain to "unlearn" pain, was more effective than a placebo and normal pain management care.

It gives credence to something that sounds completely unbelievable: In some cases, you can "mind over matter" your way to hurting less.

12. Grass screams when you cut it

Thank you to u/arealcabbage for this horrifying image:

"The grass screams distress signals to the next lawn over when you're mowing."

Believe it or not, that's true — in a sense. That freshly-cut grass smell we all like? It's actually a distress signal designed to warn other plant-life in the area of danger.

It's a stretch to say that your lawn feels pain, but it does have some survival instincts. Now if we could only say for sure why humans love the smell so much!

A student accidentally created a rechargeable battery that could last 400 years

"This thing has been cycling 10,000 cycles and it’s still going." ⚡️⚡️

Steve Zylius/University of California, Irvine.

There's an old saying that luck happens when preparation meets opportunity.

There's no better example of that than a 2016 discovery at the University of California, Irvine, by doctoral student Mya Le Thai. After playing around in the lab, she made a discovery that could lead to a rechargeable battery that could last up to 400 years. That means longer-lasting laptops and smartphones and fewer lithium ion batteries piling up in landfills.

A team of researchers at UCI had been experimenting with nanowires for potential use in batteries, but found that over time the thin, fragile wires would break down and crack after too many charging cycles. A charge cycle is when a battery goes from completely full to completely empty and back to full again.

But one day, on a whim, Thai coated a set of gold nanowires in manganese dioxide and a Plexiglas-like electrolyte gel.

"She started to cycle these gel capacitors, and that's when we got the surprise," said Reginald Penner, chair of the university's chemistry department. "She said, 'this thing has been cycling 10,000 cycles and it's still going.' She came back a few days later and said 'it's been cycling for 30,000 cycles.' That kept going on for a month."

This discovery is mind-blowing because the average laptop battery lasts 300 to 500 charge cycles. The nanobattery developed at UCI made it though 200,000 cycles in three months. That would extend the life of the average laptop battery by about 400 years. The rest of the device would have probably gone kaput decades before the battery, but the implications for a battery that that lasts hundreds of years are pretty startling.

"The big picture is that there may be a very simple way to stabilize nanowires of the type that we studied," Penner said. "If this turns out to be generally true, it would be a great advance for the community." Not bad for just fooling around in the laboratory.

Drones fired ‘seed missiles’ into the dirt. A year later, the trees are already 20 inches tall.

10 drones can plant 400,000 trees in a day — enough to combat climate change in real time.

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."

According to Fedoranko, just two operators could send out a mini-fleet of seed missile planting drones that could plant 400,000 trees a day -- a number that quite possibly could make massive headway in combating the effects of manmade climate change.

The drones were designed by an ex-NASA engineer. And with a pressing need to reseed an area in Myanmar equal to the size of Rhode Island, the challenge is massive but suddenly within reach. Bremley Lyngdoh, founder and CEO of World Impact, says reseeding that area could theoretically house as many as 1 billion new trees.

"Obviously, planting a billion trees will take a long time without the help of drones," Lyngdoh told Fast Company.

But they've now got a powerful new ally in their corner. For context, it took the Worldview Foundation 7 years to plant 6 million trees in Myanmar. Now, with the help of the drones, they hope to plant another 4 million before the end of 2019.


Myanmar is a great case study for the project. In addition to the available land for the drone project, the nation has been particularly hit by the early effects of climate change in recent years. Rising sea levels are having a measurable impact on the population. In addition to their ability to clear CO2 from the atmosphere, healthy trees can also help solidify the soil, which can reduce the kind of soil erosion that has been affecting local populations in Myanmar.


Going forward, technologies like seed-planting drones could help stem the tide of catastrophic climate change while our governments and societies work to change the habits of consumers and corporations that are driving the problem. Our endless hunger for new technology may be the driving force behind climate change and deforestation but it could also end up being the solution to a problem.

Conjoined twins with fused brains separated; surgeons practiced for months in virtual reality

Arthur and Bernardo finally get to see each other face to face.

Surgeons prepared to separate 3-year-old conjoined twins in Brazil using virtual reality.

The things human beings have figured out how to do boggles the mind sometimes, especially in the realm of medicine.

It wasn't terribly long ago that people with a severe injury had to liquor up, bite a stick, have a body part sewn up or sawed off and hope for the best. (Sorry for the visual, but it's true.) The discoveries of antibiotics and anesthesia alone have completely revolutionized human existence, but we've gone well beyond that with what our best surgeons can accomplish.

Surgeries can range from fairly simple to incredibly complex, but few surgeries are more complicated than separating conjoined twins with combined major organs. That's why the recent surgical separation of conjoined twin boys with fused brains in Brazil is so incredible.


The twins, Bernardo and Arthur Lima, are almost 4 years old and have never seen one another's face. They've spent their lives conjoined at the top of their heads, facing opposite directions. Born as craniopagus twins (joined at the cranium), their brains were also fused together, making their separation extremely complex. According to the BBC, they've been cared for at the Instituto Estadual do Cérebro Paulo Niemeyer (Paulo Niemeyer State Brain Institute) in Rio de Janeiro for the past two and a half years.

Surgeon Noor ul Owase Jeelani is the founder of medical charity Gemini Untwined, which funded the surgery. He helped lead the team of nearly 100 medical workers who worked for months to prepare for the boys' separation, which was one of the most complicated of its kind.

Jeelani told the BBC that it was the first time surgeons in separate countries practiced by operating in the same "virtual reality room" together, wearing VR headsets.

"It's just wonderful," he said. "It's really great to see the anatomy and do the surgery before you actually put the children at any risk. You can’t imagine how reassuring this is for the surgeons. To do it in virtual reality was just really man-on-Mars stuff."

Watch Jeelani explain how they prepared for the procedure:

Prior attempts to separate the twins had been unsuccessful, making the surgery even more challenging due to scar tissue. However, after multiple surgeries that took more than 33 hours collectively, the boys were successfully separated in June.

“It was without a doubt the most complex surgery of my career,” said neurosurgeon Gabriel Mufarrej of the Paulo Niemeyer State Brain Institute, according to EuroNews. “At the beginning, nobody thought they would survive. It is already historic that both of them could be saved."

Jeelani told the BBC that the boys' heart rates and blood pressure were "through the roof" for four days after the surgery—until they were reunited and touched hands.

According to Reuters, Bernardo and Arthur are the oldest twins with fused brains to be successfully separated. They will spend the next six months in rehabilitation.

Congratulations to the Lima family and to the global team that combined dedication, perseverance and the miracle of modern technology to create a brighter future for these young boys.
