He created the artwork between 1495 and 1496 with the intention of depicting the exact moment after Jesus reveals that one of his friends will betray him.Specifically, the apostles' expressions of rage and shock. Despite being one of the world's largest and most famous paintings, you won't be able to see it in a museum. It has a permanent residence in a convent in Milan, Italy.

Centipede is a Latin word that means "hundred legs," but that name is actually quite deceptive. Since centipedes only have one set of legs per body segment and they are always oddly shaped, they can never have exactly 100 legs. Each species of centipede has a different number of legs. Some species only have 15 pairs, while others have 177 pairs!

 Historical records state that 2000 people helped with his funeral arrangements. His army killed these 2000 individuals. Then, his escort killed the army. In addition, the escort killed anyone who got in their way so they could hide and bury him there. Finally, according to the legend, they committed suicide upon arriving at their destination. The slaves who built Genghis Khan's tomb were also murdered by his soldiers after it was finished. After that, soldiers perished as well. Thus, anyone who is aware of the burial site was either dead or killed.

The first train in India began service on April 16, 1853. Mumbai Locals are the world's busiest railroads, carrying over 2.2 billion people each year. Mumbai also features India's most out-of-date electric train network, established in 1925.

After regular services were discontinued, some Cambodians built their own trains out of bamboo. It is now a popular tourist destination and a must-see for anybody visiting Cambodia.

Every second, around 28 million litres (700,000 gallons) of water flow down Niagara Falls. It is believed to be the fastest-moving waterfall in the world. With a height of 188 feet (57 meters) and a depth of 170 feet (52 meters), Horseshoe Falls is the tallest waterfall. Glacier action caused Niagara Falls to develop some 12,000 years ago.

According to the Committee on the Medical Effects of Air Pollutants (COMEAP), outdoor air pollution causes up to 36,000 premature deaths in the UK each year. 29,000 premature deaths per year are caused by fine particle air pollution. The harmful gas nitrogen dioxide's (NO2) impact raises the number to 36,000 every year.

If you've always wanted to be a ninja, now is the moment to make your dreams come true. The Japanese city of Iga, which claims to be the home of the ninja and has a strong history of martial arts experts, experienced a ninja scarcity in 2018. However, they're prepared to pay as much as $85,000 for performative ninjas willing to staff their annual ninja festival.

The Netherlands could be crammed into Mongolia 37 times. It is the world's 18th most populous country (Iran is 17th).

Henna twigs are still used as toothpicks by the local population in rural North Africa to maintain healthy gums and clean teeth. Who would have guessed that Mehendi could be used to save money on dental bills?

International Asteroid Day was established in 2016 by the UN General Assembly. The time was not picked at random. The Tunguska meteorite was created when a celestial body exploded above Siberia on June 30, 1908.

Egypt is home to one of the world’s largest dams. The Aswan High Dam is the world’s largest embankment dam, spanning across The Nile separating Egypt from Sudan and creating Lake Nassar. Lake Nassar is one of the world’s largest reservoirs.

While this seems like a great feat, when we cycled from Egypt to Sudan, we saw the devastation that this dam caused. At one time, Sudan was lush and green along the Nile and even tourists from the UK would vacation in Wadi Halfa in Sudan. Today, it is a dried-up mess thanks to the damming of Lake Nassar.

Many people argue that candy corn tastes like chicken feed, but that is not how it got its name. George Renninger invented it in the 1880s, and Goelitz Confectionery Company (now Jelly Belly Co.) popularised it around the turn of the century. Because corn was used to feed chickens, the product was dubbed "Chicken Feed," and the box featured a colourful rooster.

Another etiquette guideline that struck me was the prohibition on covering your dishes with crumpled-up napkins and debris. That, according to our advisor, demonstrates a lack of regard for the restaurant workers and the meal they delivered. She recommended folding (or even tying a bow!) in our used napkins.

Aliens may inhabit one out of every 37 to one out of every 70 sun-like stars. These discoveries alone suggest that there are billions of planets in our galaxy that potentially support life.

Why do some survive traumatic events and come through seemingly unscathed? And yet others develop anxiety disorders like PTSD, Panic Disorder, and Generalized Anxiety Disorder. One thing is certain: anxiety disorders and anxious temperaments seem to run in families. Studies also show that individuals who are genetically predisposed to anxiety are at a higher risk of developing anxiety after exposure to traumatic or stressful events.

There are basically three types of termites: the king or queen, the soldiers, and the workers, while we're talking about the social lives of termites. Every colony of termites contains these various termites, and no colony could survive without all three. Despite their natural rivalry, they are strikingly similar to ants in this respect.

The berry is used in a variety of ways by First Nations people. It can be consumed raw or combined with dried meat to make the traditional dish pemmican. In addition to being used to treat coughs, the juice is used to make dye.

The appendix used to be mainly disregarded as being useless. The appendix would need to be removed in the event of appendicitis, a potentially fatal condition. The vermiform appendix was the subject of study by Randal et al. in 2007 at Duke University. The probiotic bacteria in the appendix were found to release when the body was being attacked by a particular sort of infection, as was discovered by the researchers. When the body is contaminated, the appendix accomplishes this by releasing them into the cecum.

Over 37,000 people gather at Stonehenge in southern England to observe the summer solstice. Druids and agnostics are among the people who commend the longest day of the year at this striking spot.

That is correct. They can transition from one gender to another at any time. The switch is determined by which is most suitable for mating at the time. Oysters normally begin as males and mature into females. Another fascinating oyster truth is that the substrate to which it attaches itself shapes this sea species! It adheres to the surface occupied by a cluster of oysters (known as the bed) and continues to build around it.
