Cairo is Africa's and the Middle East's biggest metropolis, with a population of 22 million people and an area of around 500 square kilometres. It's also one of the world's most populous cities.

A female shrimp will give birth to an insane number of eggs that will hatch in two weeks during a single season. As long as there is food, they can also thrive in any.

There is no clear link between a full moon and howling wolves. Wolves communicate by howling, and they elevate their heads to make the sound go further. Wolves may also howl in full darkness. However, because moonlight evenings are generally windless, the howling is just easier to hear. Furthermore, without moonlight, it is impossible to observe a howling wolf.

Ella Slack is of comparable height and size as the queen, thus she will perform a rehearsal before major events to eliminate royal annoyances such as the sun getting in Her Majesty's eyes. Slack has been doing it for three decades, but she is not permitted to sit on the throne, so she must kneel above it.

No, caramel and dulce de leche are not synonymous. Caramel, as we all know, is nothing more than water and sugar. Dulce de leche, on the other hand, is milk and sugar, as the name suggests (if you've practiced your Spanish).

When an enzyme called luciferase is present, oxygen reacts chemically with calcium, adenosine triphosphate (ATP), a chemical called luciferin, and other substances inside the firefly's light organ to produce light.

Consider speeding to 100 mph and returning to zero in less than four seconds. If you have a cardiac issue, you may not live. The sensation is similar to being pressed by an invisible force. In such a circumstance, breath control is critical, and F1 drivers must go through many drills to prepare for G-Force. Formula 1 vehicles are capable of such a feat because they must sharply stop while approaching curves and then accelerate swiftly, as it is a race against time. When the drivers are subjected to force, their stamina and overall physical condition are tested.

In a way. After Tobey Maguire was injured on the set of Seabiscuit, Jake Gyllenhaal, who plays the duplicitous and theatrical Quentin Beck/Mysterio, was rumoured to be taking over for him in 2004's Spider-Man 2. Maguire recovered in time to reprise his role as Peter Parker, so the point was moot. However, Gyllenhaal has admitted that he was one of several actors considered for the emergency fill-in role.

Onychophagia. Between 25 and 30 percent of kids are thought to bite their nails regularly.

He did at first, but it didn't last long. After 1928, Walt stopped animating in favour of concentrating on the direction and development of stories. He trusted Iwerks and other accomplished artists to handle the grunt work of drawing. In fact, it's likely that he only ever really drew Mickey when people asked for his autograph. He never included Mickey in any of his theatrical releases.

Sand is combined with lime and soda ash and heated to extremely high temperatures to create glass. Glass is produced when the liquid combination is allowed to cool again.

In stark contrast to their modern-day high status, lobsters were routinely fed to convicts during colonial times (and slaves). They were filthy, inexpensive, and everywhere. Prisoners were ordered to limit their consumption of lobster to three days a week when they became sick of it.

Taman Negara is the world's oldest tropical rainforest, believed to be more than 130 million years old. Taman Negara translates to "national park" in Malay. To enter the park, you must obtain special authorization from the government, but it is definitely worth it if you have the time. Rare creatures like as the Malayan tiger, crab-eating macaques, Sumatran rhinos, and even the Asian elephant call this jungle home.

One of the sweetest facts about the Netherlands is that the Dutch adore licorice. They eat around two kilos per person per year. That’s around 32 million kilos of the sweet treat consumed each year! 

You’ll be spoilt for choice, with shops in the Netherlands selling over 80 different kinds of drop (the Dutch word for licorice).

On September 2nd, the World Coconut Day was founded to honour the benefits of the coconut. The day emphasises the value and application of coconuts. Remember to celebrate that day!

Antarctic krill are not tiny, despite a common misconception. Yes, Antarctic krill (hence referred to as krill) are categorised as zooplankton, but they are not minuscule; they are larger than several commercially available shrimp species and are around the size of an adult human pinkie. In fact, this variety of krill's Latin name, Euphausia superba, implies that it is the largest and finest species of krill.

If you notice yourself becoming more upbeat during the warmer months, you are not alone. For a 2011 study published in the journal Science, researchers examined the tweets of 2.4 million people from around the world over a two-year period. They discovered that when the change in daylight was positive (i.e., as the summer solstice approached), users tweeted considerably happier tweets than when the change in daylight was negative (i.e., as the winter solstice approached).

The Ritz-Carlton occupies the 118th level of Hong Kong's tallest building, the International Commerce Centre (ICC), and contains the world's highest outdoor bar and swimming pool.

Only around 50% of PCOS patients are obese. Thin PCOS patients do have other features of PCOS like excess facial hair, irregular menstrual cycles, and anovulation. On ultrasound, there will be a polycystic pattern (multiple cysts) in the ovaries.

Jules' wallet in Pulp Fiction that reads "Bad #&$&*@$" actually belonged to the director—who picked it up because of its reference to the 1971 film Shaft. As it happened, Samuel L. Jackson would go on to play the character that inspired the wallet in the 2000 remake of Shaft.

Bed bugs are nearly impossible to eradicate and can spread as quickly as water cooler gossip. But it's also possible that's why they've lasted so long. According to a 2019 study published in Current Biology, scientists believe that the bugs have been around since the time of the dinosaurs, first appearing around 115 million years ago. "It was a revelation to think that the pests that live in our beds today evolved more than 100 million years ago and were walking the earth alongside dinosaurs," said researcher Mike Siva-Jothy. "It demonstrates that the evolution of bed bugs is far more complex than we previously thought."

Saint Nicolas, a Christian saint and Greek Bishop of Myra, was born in Patara, Lycia, or what is now known as Demre in Turkey. Also, it is believed that the Virgin Mary's ultimate resting place is someplace near Ephesus.

Developed in 1819 by the French army, soldiers used it to communicate at night without speaking or using candles. Fifteen-year-old French schoolboy Louis Braille learned about the code, and eventually developed the more usable, streamlined version of the braille alphabet we know today.
