The colour of a chicken's earlobes—yes, chickens have earlobes—is a good predictor of the colour of the eggshell it will lay. Chickens with white earlobes lay white eggs, whereas chickens with red or brown earlobes lay brown eggs.

This is an unfortunate fact because many of us have been told the opposite and have tried to cut it far too frequently. However, it is important to remember that split ends prevent our hair from growing, which means that we must cut them as soon as they appear.

Water also changes the hydrogen bonds in our hair, making it flatter after a shower. This could explain why some women dislike humidity: the water in the air changes the silkiness and structure of the hair, causing some hair to become frizzy or puffy.

It's true whether you believe it or not. Pineapple contains an enzyme called bromelain, which is a little-known fact. If you read other sources, you'll notice that they all say pretty much the same thing. This enzyme degrades proteins in your mouth, specifically your taste buds. This can ruin your palate for the rest of the day until your mouth heals. A fun fact that many people believe is that the enzyme bromelain is used in meat tenderizer. Pineapple is a fruit, so it's good for you. However, you should let a freshly sliced pineapple sit in the fridge for a few minutes before eating it so the enzymes can break down.

Pilots are paid hundreds of dollars per day to stand by during the summer in case it rains and trees require emergency blow-drying. It may appear absurd, but it is worthwhile for farmers who grow the delicate, expensive fruit. The work is hazardous; pilots are frequently injured in orchard crashes.

We may think of processed cheese as a uniquely American invention (think Kraft and Cheez Whiz), but it turns out that the Swiss invented it first. According to the Michigan Dairy Review, processed cheese was invented in 1911 by Walter Gerber and Fritz Stettler in Switzerland to improve the shelf-life of cheese before it was shipped overseas.

Here's a fun (and potentially hazardous) science experiment: If you split a grape almost in half and microwave it, it will explode into a fireball of plasma and lighting. Microwaves generate heat by using microwave radiation, according to scientists. When you microwave "nothing" — in this case, a very small grape that doesn't absorb enough power — the electromagnetic waves have nothing to work on and become concentrated.

Since you were a child, you've probably heard the phrase "candy will rot your teeth." However, there are many foods that are worse for your dental hygiene than candy, such as crackers. This is because acid, not sugar, is the leading cause of tooth decay.

In 2012, when Boeing wanted to test its wireless signal on new planes, they placed massive piles of potatoes on the seats. Potatoes absorb and reflect radio and wireless signals in the same way that humans do due to their high water content and chemical makeup.

"When things are going well, [romantic love] is a very powerfully wonderful addiction," said Helen E. Fisher, a biological anthropologist at Rutgers University, in a 2006 TED Talk. That's because the hormones released by your brain when you're in love are intensely euphoric, to the point of making you addicted to love—and the person you're in love with.

People may try to convince you that long-distance relationships can't and won't work, but research shows otherwise. According to one study published in the Journal of Communication, long-distance relationships are not only as successful as regular ones, but they are also more effective in building trust and satisfaction between partners.

During International War I, Europe was at war, and world powers like Britain were organizing their armies. By 1917, one renowned British admiral of the Royal Navy had retired and wrote to Winston Churchill to express his thoughts on the day's headlines, some of which were so thrilling that he wrote, "O.M.G. (Oh! My! God!)." How could he have realized that the acronym he created would go on to become one of the world's most-used phrases?

Social media and digital consumption have grown so pervasive in most areas of the world that it's easy to forget that reading is still a major form of pleasure for some individuals. A 2017 survey found that the average Indian spends 10 hours and 42 minutes per week reading. In comparison, Americans work five hours and 42 minutes each week. Thailand, China, the Philippines, and Egypt round out the top five nations.

Officials in the Netherlands erected a rodent-only bridge to ensure safe passage for squirrels attempting to cross the N44 highway. While it was a generous gesture, it may not have been the most cost-effective: the bridge cost £120,000 and was utilized by only five squirrels over a two-year period. "Three squirrels were observed on the bridge in 2014, and two squirrels were spotted in 2015," the ministry stated in a statement.

The blue whale is the world's biggest mammal, weighing up to 150 tons and reaching up to 90 feet long. A large animal would, of course, have a massive heart. The heart of a blue whale is approximately the size of a small vehicle and weighs about 1,300 pounds. Its heart beats so fast to pump blood through its massive body and arteries that you can hear it from two kilometres distant. You could miss it, though, because its heart beats only eight to ten times each minute.

Dogs' ears, in addition to being able to move in a variety of ways, can hear considerably higher frequency noises than human ears. In fact, dogs can hear noises that are twice as far away as we can—and it looks that tiny dogs are even better at it. This is due to the fact that the smaller a mammal's head is, the more frequencies it can take up and compare in each ear. That is how they (and us) determine the source of noises.

When you find your dog eating on something he shouldn't, he averts his gaze and assumes a submissive stance. That indicates he recognizes his error and expresses regret, correct? Scientists believe it's unlikely. It's more likely that the behaviors that owners identify with a dog's remorse are a reaction to being reprimanded. They just do not consider their violation as thoroughly as you do.

Napoleon Bonaparte, the great conqueror, was once assaulted by...bunnies. The emperor had asked for a rabbit hunt for himself and his troops. His chief of staff organized it and had soldiers collect up 3,000 bunnies for the occasion. The hunt was set to begin after the rabbits were freed from their cages. That was the plan, at least! The rabbits, on the other hand, raced toward Bonaparte and his soldiers in a vicious and relentless onslaught. And we were told that Waterloo was the greatest defeat of the conqueror...

A student went 264.4 hours without sleep while still in high school, winning first place in the 10th Annual Great San Diego Science Fair in 1964. Randy said emphatically "no" when asked if he'd do it again. Others claim to have broken Randy's record, but none of their attempts were done under close scrutiny, as Randy's were, so there's no way of knowing if they're genuine.

Red has the longest wavelength of all the colours, which scientists believe makes it easier to process in the developing receptors and nerves in a baby's eye. This certainly explains why every baby adores Elmo!

According to American sociologists, children who learn to read by the age of eight have a lower chance of being imprisoned in the future. Furthermore, those children are less likely to use drugs or drop out of school. Isn't this helpful and interesting?

Many psychological and social studies indicate that there is a significant pattern in how people choose people with whom to form romantic relationships. This pattern is explained by the Matching Hypothesis, which states that people are more attracted to those with whom they share a level of attractiveness, or who are equally socially desirable. Even if successful couples differ in physical attractiveness, one of them usually compensates for it with other socially desirable qualities.

Wade Wilson, the protagonist of Marvel's Deadpool, was initially conceived as a parody of DC's Deathstroke, Slade Wilson. The name "Wade Wilson" was an inside joke for being "connected" to "Slade Wilson." Later, Deadpool was reimagined as a crazy smartass anti-hero.

Walt Disney may have been the first to put gloves on his characters, as shown in Mickey Mouse's 1929 film The Opry House. Aside from being simpler to animate, Disney chose gloves for another reason: “We didn't want Mickey to have mouse hands because he was meant to be more human,” Disney told his biographer in 1957.

During World War I, there was a cotton scarcity, therefore Kimberly-Clark created a thin, flat cotton replacement that the army sought to employ as a filter in gas masks. Because the war ended before scientists were able to perfect the material for gas masks, the firm redesigned it to be smoother and softer, then sold Kleenex as facial tissue instead.
