A Simple Trick to Prevent Songs From Getting Stuck in Your Head

We’ve all been victims of the earworm: a catchy piece of music gets stuck in our heads and no matter what we do, we can’t seem to dislodge it. Earworms are incredibly common; 90% of us suffer from earworms at least once a week. And while they’re not actually harmful, they can be really distracting. In one survey, a third of participants classified their earworms as “unpleasant,” which is a nice way of saying “severely annoying.” Some people claim they can control this phenomenon, but most of us just have to suffer through it. But fear not! Researchers have come to the rescue with a scientifically backed earworm prevention weapon: bubble gum. 

Yes, scientists at the University of Reading, UK say the best way to treat earworms is to chew gum. 

Why we get earworms in the first place isn’t entirely clear, but one likely culprit is the brain’s auditory cortex, which processes sound. Dr. Philip Beaman, an associate professor of cognitive science at the University of Reading, says the brain’s tendency to repeat a familiar tune “may be a form of involuntary musical memory.” One proven method for degrading short-term memory is to repeat a random word over and over again in your head (the official term for this is “irrelevant sub-vocalisation”). Previous studies have shown that “mouthing something random like the first few letters of the alphabet while looking at a list of words makes most people forget 1/3 to 1/2 of the words on the list,” explains Deborah Netburn at the Los Angeles Times. The act of chewing gum has a similar effect, the new research suggests, and “therefore can be recommended as an aid to get rid of earworms.”

If you’re not a fan of gum, you could also pick up a puzzle book when you can’t shake an annoying song. Previous research suggests solving a tough anagram or sudoku can help. “The key is to find something that will give the right level of challenge,” Dr. Ira Hyman, a music psychologist at Western Washington University, told the Telegraph. “If you are cognitively engaged, it limits the ability of intrusive songs to enter your head.” 

You don’t want something too difficult or your mind will wander, and you don’t want something too easy. “It is like a Goldilocks effect – it can’t be too easy and it can’t be too hard, it has got to be just right,” Hyman says

Others fight off earworms with another song, psychologist Vicky Williamson told NPR. “Some people think that the British national anthem sung quite slow is good for getting rid of earworms,” she says.

In case you were wondering, some of the most common earworms, according to researchers, are: “Single Ladies” by Beyonce; “Bad Romance” by Lady Gaga; and “I Want To Hold Your Hand” by The Beatles. I’d also like to add “Let It Go” from the movie Frozen.

12 Intriguing Facts About the Intestines

When we talk about the belly, gut, or bowels, what we're really talking about are the intestines—long, hollow, coiled tubes that comprise a major part of the digestive tract, running from the stomach to the anus. The intestines begin with the small intestine, divided into three parts whimsically named the duodenum, jejunum, and ileum, which absorb most of the nutrients from what we eat and drink. Food then moves into the large intestine, or colon, which absorbs water from the digested food and expels it into the rectum. That's when sensitive nerves in your rectum create the sensation of needing to poop.

These organs can be the source of intestinal pain, such as in irritable bowel syndrome, but they can also support microbes that are beneficial to your overall health. Here are some more facts about your intestines.

1. The intestines were named by medieval anatomists.

Medieval anatomists had a pretty good understanding of the physiology of the gut, and are the ones who gave the intestinal sections their names, which are still used today in modern anatomy. When they weren't moralizing about the organs, they got metaphorical about them. In 1535, the Spanish doctor Andrés Laguna noted that because the intestines "carry the chyle and all the excrement through the entire region of the stomach as if through the Ocean Sea," they could be likened to "those tall ships which as soon as they have crossed the ocean come to Rouen with their cargoes on their way to Paris but transfer their cargoes at Rouen into small boats for the last stage of the journey up the Seine."

2. Leonardo da Vinci believed the intestines helped you breathe.

Leonardo mistakenly believed the digestive system aided respiratory function. In 1490, he wrote in his unpublished notebooks, "The compressed intestines with the condensed air which is generated in them, thrust the diaphragm upwards; the diaphragm compresses the lungs and expresses the air." While that isn't anatomically accurate, it is true that the opening of the lungs is helped by the relaxation of stomach muscles, which does draw down the diaphragm.

3. Your intestines could cover two tennis courts ...

Your intestines take up a whole lot of square footage inside you. "The surface area of the intestines, if laid out flat, would cover two tennis courts," Colby Zaph, a professor of immunology in the department of biochemistry and molecular biology at Melbourne's Monash University, tells Mental Floss. The small intestine alone is about 20 feet long, and the large intestine about 5 feet long.

4. ... and they're pretty athletic.

The process of moving food through your intestines requires a wave-like pattern of muscular action, known as peristalsis, which you can see in action during surgery in this YouTube video.

5. Your intestines can fold like a telescope—but that's not something you want to happen.

Intussusception is the name of a condition where a part of your intestine folds in on itself, usually between the lower part of the small intestine and the beginning of the large intestine. It often presents as severe intestinal pain and requires immediate medical attention. It's very rare, and in children may be related to a viral infection. In adults, it's more commonly a symptom of an abnormal growth or polyp.

6. Intestines are very discriminating.

"The intestines have to discriminate between good things—food, water, vitamins, good bacteria—and bad things, such as infectious organisms like viruses, parasites and bad bacteria," Zaph says. Researchers don't entirely know how the intestines do this. Zaph says that while your intestines are designed to keep dangerous bacteria contained, infectious microbes can sometimes penetrate your immune system through your intestines.

7. The small intestine is covered in "fingers" ...

The lining of the small intestine is blanketed in tiny finger-like protrusions known as villi. These villi are then covered in even tinier protrusions called microvilli, which help capture food particles to absorb nutrients, and move food on to the large intestine.

8. ... And you can't live without it.

Your small intestine "is the sole point of food and water absorption," Zaph says. Without it, "you'd have to be fed through the blood."

9. The intestines house your microbiome. 

The microbiome is made up of all kinds of microorganisms, including bacteria, viruses, fungi, and protozoans, "and probably used to include worm parasites too," says Zaph. So in a way, he adds, "we are constantly infected with something, but it [can be] helpful, not harmful."

10. Intestines are sensitive to change.

Zaph says that many factors change the composition of the microbiome, including antibiotics, foods we eat, stress, and infections. But in general, most people's microbiomes return to a stable state after these events. "The microbiome composition is different between people and affected by diseases. But we still don't know whether the different microbiomes cause disease, or are a result in the development of disease," he says.

11. Transferring bacteria from one gut to another can transfer disease—or maybe cure it.

"Studies in mice show that transplanting microbes from obese mice can transfer obesity to thin mice," Zaph says. But transplanting microbes from healthy people into sick people can be a powerful treatment for some intestinal infections, like that of the bacteria Clostridium difficile, he adds. Research is pouring out on how the microbiome affects various diseases, including multiple sclerosis, Parkinson's, and even autism.

12. The microbes in your intestines might influence how you respond to medical treatments.

Some people don't respond to cancer drugs as effectively as others, Zaph says. "One reason is that different microbiomes can metabolize the drugs differently." This has huge ramifications for chemotherapy and new cancer treatments called checkpoint inhibitors. As scientists learn more about how different bacteria metabolize drugs, they could possibly improve how effective existing cancer treatments are.

This 3D-Printed Sushi is Customized For You Based on the Biological Sample You Send In

Open Meals

Many high-end restaurants require guests to make a reservation before they dine. At Sushi Singularity in Tokyo, diners will be asked to send fecal samples to achieve the ideal experience. As designboom reports, the new sushi restaurant from Open Meals creates custom sushi recipes to fit each customer's nutritional needs.

Open Meals is known for its experimental food projects, like the "sushi teleportation" concept, which has robotic arms serving up sushi in the form of 3D-printed cubes. This upcoming venture takes the idea of a futuristic sushi restaurant to new extremes.

Guests who plan on dining at Sushi Singularity will receive a health test kit in the mail, with vials for collecting biological materials like urine, saliva, and feces. After the kit is sent back to the sushi restaurant, the customer's genome and nutritional status will be analyzed and made into a "Health ID." Using that information, Sushi Singularity builds personalized sushi recipes, optimizing ingredients with the nutrients the guest needs most. The restaurant uses a machine to inject raw vitamins and minerals directly into the food.

To make things even more dystopian, all the sushi at Sushi Singularity will be produced by a 3D-printer with giant robotic arms. The menu items make the most of the technology; a cell-cultured tuna in a lattice structure, powdered uni hardened with a CO2 laser, and a highly detailed model of a Japanese castle made from flash-frozen squid are a few of the sushi concepts Open Meals has shared.

The company plans to launch Sushi Singularity in Tokyo some time in 2020. Theirs won't be the first sushi robots to roll out in Japan: The food delivery service Ride On Express debuted sushi delivery robots in the country in 2017.
