Ear rumbling is a special 'superpower' that not everyone has

Can you do this?

via Eltpics / Twitter

Mapping out the structure of the inner ear.

There are no two human beings who are exactly alike. One of the funny quirks of evolution is that some of us can do things with our bodies we think are routine, but are impossible for others.

Some people can wiggle their ears, others can't. Some can wiggle their nose like Samantha from "Bewitched" while others just look really silly when making an attempt.

Not everyone can lick their elbow but most wouldn't attempt to do so in public.

A Twitter user named Massimo dropped some knowledge about a skill that not everyone has and even fewer discuss: ear rumbling.

Those of us who can do it know exactly what it is, while it's a mystery to those who cannot.

People who can ear rumble have the ability to control the tensor tympani, a muscle within the ear. Contracting the muscle creates a rushing, rumbling sound that, if flexed enough, can drown out a significant amount of noise.

This can be useful when someone is saying something that you don't want to hear but don't want to be rude and cover your ears. It can come in real handy if someone is about to spoil your favorite TV show or if you live with someone who can't stop nagging.

Some people cannot voluntarily create the rumbling sound but hear it when they let out a large yawn.

There's a Reddit sub-forum just for ear rumblers with over 60,000 people. Here's how some of them get rumblin'.

"I just squeeze the muscle in my ears I guess," — melvinthefish

"When I flex and hold whatever I'm manipulating to do that, I get my rumble," — ttywzl

"I get a mild rumble just doing the usual flex, but i can make it a bit louder by bringing my top lip up to my nose," — Willmono7

"The best way I can describe it is I 'squint my ears,'" —SteeleIT

The muscle exists to mask-low frequency sounds so we can focus on those at a higher frequency. It also works to mute sounds we create ourselves such as eating potato chips or coughing. It's a way that helps us from becoming annoyed with our own bodies.

Unfortunately, the muscle has a rather slow reaction time so it cannot prevent us from hearing loud sudden noises like a gunshot or a book slamming on the ground.

Massimo's tweet caused quite a stir on the platform.

Although scientists have known about ear rumbling since at least the 1800s, there doesn't appear to have been too much research on the topic. We know that some can rumble and others cannot, but it's unclear how it breaks down percentage-wise or if it's more prevalent in certain groups.

The good news is that the word is starting to get out and people who've been rumbling all their lives suddenly don't feel so alone.

Not all conspiracy theories are fake news. These 6 actually turned out to be true

Almost too outlandish to believe. Almost.

What's real and what isn't?

It’s feeling harder and harder to separate truth from fiction in the age of fake news.

But conspiracy theories and propaganda are as old as society itself. Perhaps most disturbing of all is the growing wealth of scientific evidence suggesting that we’re influenced even by news we know to be fake.

How many disproven JFK assassination theories are floating around in your brain thanks to Oliver Stone? Do you sometimes wonder if anyone has ever really landed on the Moon? And do you think just maybe it’s possible that Adolf Hitler actually survived World War II and lived out his days in Brazil? If so, you’re not alone.


And that’s to say nothing of more modern conspiracy theories driven by social media, making unfounded claims about everything from diets to money to the state of reality itself.

But sometimes the wildest conspiracies are true. Like these six seemingly insane conspiracy theories that are quite real:

1. "Gaydar"

Who doesn’t love Canada? Well, 1960’s Canada wasn’t quite the squishy utopia it seems to be today. The Canadian government hired Carleton University professor Frank Robert Wake to create something it maliciously called the “fruit machine,” which they believed could detect and identify gay men. It wasn’t part of some benign effort to understand human sexuality.

It was part of a sick bit of McCarthyism with the stated goal of getting all gay men out of the country’s government.

More than 400 people lost their jobs, and 9,000 more were kept on a file of “suspects.” The device claimed to work by measuring how much a subject’s pupils dilated after being forced to look at same-sex erotic imagery.

2. MKUltra

Back in the 1950s the CIA secretly dosed individuals with LSD in order to test the potential effects of mind control. Although the practice reportedly continued for two decades, it was launched before the drug movement of the 1960s made LSD into a popular counterculture symbol. And while being given some free acid might sound like a great time to some, or at least the plot to a bad hipster action movie, dozens of people were reportedly left with permanent disabilities after secretly being subjected to massive amounts of LSD and electroshock therapy after seeking treatment for “minor psychiatric complaints.”

3. The Gulf of Tonkin incident

On August 2, 1964, the USS. Maddox opened fire on what it later claimed were several North Vietnamese targets. The skirmish deepened America’s involvement in the Vietnam War, leading to the death of thousands of U.S. soldiers and many more Vietnamese, including hundreds of thousands of civilians. Except, it turned out the “targets” the Maddox fired upon didn’t actually exist. It’s still debated today whether the incident was an intentional misdirection by the military. But one thing is certain: President Johnson’s original claim that the North Vietnamese fired first has been debunked. Even former Defense Secretary Robert McNamara admitted as much in an interview before his death. After all, it’s kind of hard to start a fight when you’re not even there.

4. Bohemian Grove: A secretive gathering of world elites

A secretive organization of people that control the world? Well, it turns out it does exist and many of its members are powerful world leaders and titans of industry. The real action happens at Bohemian Grove, which appears to primarily exist as a place “where the rich and powerful go to misbehave” according to The Washington Post.

Or, alternatively, to hear it from the group directly, where members, “share a passion for the outdoors, music, and theater.” However, along with more traditional fare such as drinking and big dinners, the regular activities also reportedly include performing rituals before a giant wooden owl, according to The Post.

Owners of the property host a two-week retreat in California each year for some of the wealthiest and most influential Americans. Past attendees include Richard Nixon and Ronald Reagan, both of whom attended before entering the White House. Oh, and it’s where the idea for the atomic bomb was first sketched out.

No big deal.

5. The CIA helped fund the Dalai Lama

Who doesn’t love the Dalai Lama?

Other than the Chinese government.

Even the CIA can’t get enough of His Holiness and his band of Tibetan resistance fighters. That’s because during the 1960s, the CIA allegedly funneled millions of dollars to the Tibetan Resistance, including what some claim was a six-figure annual “salary” that went directly to the Dalai Lama himself (which he denied). This wasn’t some remnant from the agency’s flirtation with LSD. Rather, it was a pretty obvious attempt to undermine the Chinese government, something the Chinese have complained about for decades. In declassified State Department memos, the organization says: “The purpose of the program … is to keep the political concept of an autonomous Tibet alive within Tibet and among foreign nations, principally India, and to build a capability for resistance against possible political developments inside Communist China.”

6. The conspiracy to kill Abraham Lincoln

The most commonly held version of events is that actor John Wilkes Booth acted alone when he assassinated President Lincoln inside Ford’s Theater. But it turns out Booth collaborated with no less than 9 other co-conspirators, including Mary Surratt, the first woman executed by the U.S. government. First, there was David Herold, who helped Booth escape after leaving Ford’s Theater. Then, there was George Azterodt, who unsuccessfully attempted to assassinate Vice President Andrew Johnson. Even though Azterodt never actually attempted the act, he was, nonetheless, executed for plotting against the president. Meanwhile, coconspirator Lewis Powell did attempt to assassinate Secretary of State William Seward, severely injuring him. If you ever want to learn the full story of Booth’s traitorous act, and the desperate attempt to capture him and his team, you can’t do better than James L. Swanson’s Manhunt: The 12-Day Chase For Lincoln’s Killer.

Russian lieutenant shares his harrowing tale of averting nuclear war 40 years ago

Even if you don't know who Petrov was, he might be the reason you're alive today.

Soviet soldier makes a decision that may have saved all life on the planet.

And even if you don't know who Petrov was, he might be the reason you're alive today.

In the 1980s, Petrov was a lieutenant colonel in the Soviet Union's Air Defense Forces. He was in charge of watching the computers at one of the Soviety Union's nuclear early warning centers. If the Americans wanted to start a nuclear war, Petrov would be one of the first to know.

At this time, the United States and the Soviet Union were embroiled in the Cold War. Each had stockpiled tens of thousands of nuclear weapons and a nuclear war, though horrific, often seemed imminent.

Suddenly, in the early morning of Sept. 26, 1983, a siren started to scream. If Petrov's computer was to be believed, the Americans had just attacked the Soviet Union.

The word "LAUNCH" appeared in bold red letters across Petrov's computer's screen. Then it happened again and again — five missiles in all.

Petrov need to react. If a nuclear attack really was incoming, the Soviets only had a few minutes to save themselves and launch a nuclear counter attack of their own.

It was Petrov's job, his duty, to alert his superiors — but something seemed off.

Petrov sat there, trying to figure out what to do. If the Americans were attacking, why were there only six bombs? Why not the thousands they were capable of? Why weren't there corroborating reports from ground radar? Plus this particular computer system was new and unproven. It could be a malfunction.

Did Petrov really think this was enough evidence to potentially start a full-scale nuclear exchange? Kill millions of people? It was a heavy weight to bear.

"Nobody would be able to correct my mistake if I had made one," Petrov later told the BBC.

After a few pregnant minutes, Petrov made his decision.

He picked up the phone and, though he couldn't know for sure, told his superiors it was a false alarm. His level-headed thinking may have saved millions of lives.

He was right. It was a malfunction.

For his efforts, Petrov's reward would be a long time coming. In the immediate aftermath, he actually got reprimanded by his superiors. It wouldn't be until after the fall of the Soviet Union that the world learned just how close we all came to destruction and the one man who saved it.

Petrov reportedly died on May 19,2017 in a home outside Moscow. The news was not widely reported.

If you want to hear Petrov describe the incident in his own words, check out this interview with Petrov from the BBC.

Scientists studied the bones of ancient women, and we might need to rethink 'women's work'

Women of the Bronze Age were anything but weak.

Certainly not the story we've been taught to believe

Think about the illustrations you've seen of men and women of the Bronze Age who lived thousands of years ago.

Perhaps there's one you recall from your elementary school text book — in which men are probably depicted hurling bronze spears and strangling lions with their bare hands, while the women are most likely pictured leading children around, sifting through grapes or weaving tiny reeds into baskets (presumably to hold the fruits of their husbands' labor).

It's an idealized image for some. Men and women, dividing labor according to their relative physical strength. Women did important work, but entirely in the domestic sphere, in part because they were less equipped to handle difficult manual labor. Each gender in their natural place. A comforting image of the way the world is "supposed to be."

And according to new research, it's an image that's totally wrong in a major way.

According to a groundbreaking new study, Bronze Age women were jacked.

Armed with a small CT scanner and a group of student guinea pigs, University of Cambridge researchers discovered that the arm bones of Central European women of the era were roughly 30% stronger than those of modern women — and 11% to 16% stronger than those of modern women on the the world champion Cambridge women's crew team, who spend multiple hours a day training to rowing a 60-foot boat as fast as humanly possible.

"This is the first study to actually compare prehistoric female bones to those of living women," explained Alison Macintosh, research fellow at the University of Cambridge and lead author of the study, in a news release.

The paper was published in the open-access journal Science Advances.

Agriculture, it turns out, is hard work. Work that Bronze Age women handled on the reg.

Particularly grinding grain into flour, which requires the use of ludicrously heavy stones.

Based on evidence from societies that still produce bread products this way, the researchers determined the prehistoric women likely spent up to five hours a day pulverizing the edible bits so their villages could actually eat food while the men were derping around trophy hunting hyenas.

"The repetitive arm action of grinding these stones together for hours may have loaded women's arm bones in a similar way to the laborious back-and-forth motion of rowing," Macintosh said.

In addition to grinding grain, researchers speculate ancient ladies got up to a range of other muscle mass-building activities...

...including hauling food for livestock, slaughtering and butchering animals for food, scraping the skin off of dead cows and deadlifting it onto hooks to turn it into leather, and planting and harvesting crops entirely by hand.

And, while punching bears and ceremonially tossing boulders at the sun weren't on the researchers' specific list, it's at least possible the women were doing that too.

"We believe it may be the wide variety of women's work that in part makes it so difficult to identify signatures of any one specific behavior from their bones," Macintosh said.

Study senior author Jay Stock said the results suggest "the rigorous manual labour of women was a crucial driver of early farming economies."

"The research demonstrates what we can learn about the human past through better understanding of human variation today," he added.

If nothing else, the findings should complicate the way we think of "women's work" going back centuries. Since the dawn of time, mankind has had boulders to grind. Animals to wrangle. Big, heavy things to lift, and arm muscles to build. And some woman had do it.
