1 . The Canadian Fossil Discovery Centre has recently “rediscovered” an ancient shark skeleton that has been sitting in the museum’s collection for nearly 50 years. Could this shark be a part of a newly discovered ancient shark species?

This fossil’s original discovery was in 1975 on a farm just west of Morden, Manitoba. The skeleton was brought into the museum and was forgotten within the ever-growing fossil collection. The skeleton was hidden in the collections room for over 40 years and the center just recently found the fossil in its storage around eight years ago.

Adolfo Cuertara, the director of the Canadian Fossil Discovery Centre, explained that “It’s a very special shark for many reasons. It’s highly possible that we are talking about a new species.” Although the shark has not been given a scientific name yet, the museum has unofficially named the skeleton, “Dave”, in honor of the farmer on whose land the skeleton was found.

After the fossil rediscovery, Dave was exhibited at the fossil center museum. Dave is around 15 feet long and is one of the largest well-preserved shark skeletons in the entire world. Within the paleontology (古生物学) world, complete shark fossils are extremely rare due to their soft cartilage (软骨结构) which disintegrates as they age. Dave’s shark species are filter feeders with no teeth, who receive their nutrition by absorbing it out of the water. Cuertara emphasizes Dave’s uniqueness by explaining, “The shape of the jaws and the skull and the kind of structures that it has, because the preservation is really amazing, is telling us that it is probably going to be a new species. The problem is now we need scientific papers and scientific research and this paper is underway.”

The Canadian Fossil Discovery Centre is hopeful that more scientific research will provide more information on Dave’s ancient shark species. For now, Dave is currently on display at the Canadian Fossil Discovery Centre and the museum has the exhibit up to date with their current information.

4 . When ice cream maker Adrienne Borlongan first experimented with a White Rabbit flavor, she thought it tasted like “cheap vanilla (香草)”. A few weeks after she added it to her Los Angeles shop, Wanderlust Creamery, visitors showed little interest. But when Borlongan posted a photo of an ice cream cone wrapped in White Rabbit-branded paper, word quickly spread on social media.

The candy, first produced in Shanghai in the 1940s, is known for its red-white-and-blue packaging and is beloved by kids all over China. And when Chinese people began to live in other countries, their love for the white, creamy candy went with them.

Soon after Borlongan posted that photo, people were driving to Wanderlust from all over California. Since then, White Rabbit has been the mainstay of Wanderlust’s ice cream lineup and is regularly sold out in their webshop.

But the story of the ice cream is about way more than taste — it’s about the power of nostalgia (怀旧) and eye-catching branding. White Rabbit’s origins date back to a business called the ABC Company, founded in Shanghai in 1943. It was later sold to the state-owned Guan Sheng Yuan Food Group, which owns it to this day.

The mix of colorful wrappers and the sweet milky taste proved a winner. Kids from Beijing to Hong Kong grew up on the sweets, and it also became a national symbol of the country — most famously, US President Richard Nixon was given some when he made his historic visit to China in 1972.

As for the flavor? The creamy consistency (黏稠度) actually comes from milk, and there’s a piece of rice paper between the candy and the wrapper to prevent melting. Over the years, White Rabbit has tried out other flavors, including red bean and peanut. But it’s the first version that has the most nostalgia connected to it.

5 . Over the streets of Paris, France, rises the Eiffel Tower. An internationally recognized symbol of France and one of the most famous structures in the world, the Eiffel Tower was originally built as the entrance to the 1889 World’s Fair, to celebrate the 100th anniversary of the French Revolution.

More than 100 artists competed with plans for the monument, but the contract was given to Alexandre-Gustave Eiffel, a bridge builder, architect, and metals expert who had already designed the framework for the Statue of Liberty. The final design required more than 18,000 pieces of iron and 2. 5 million rivets(铆钉) to construct. It took hundreds of workers more than 2 years to finish, and when it was completed in March of 1889,it was almost 1,000 feet high—more than twice the height of the pyramids at Giza—making it the tallest structure in the world at that time.

The tower was originally meant to be a temporary structure, and only stand for 20 years. Many of the people of Paris disliked the tower. They thought it was ugly, or that it was dangerous and might fall down. By the time the tower was supposed to be removed, however, people had realized that it was a valuable way to transmit wireless telegraph and radio signals, and city officials decided to keep it. It continues to be used for communications today, with more than 100 antennas(天线) on it.

The tower is completely repainted every seven years to protect it from rusting(生锈), using 60 tons of paint each time. Originally, the tower was reddish brown and the color was changed sometimes when it was repainted. These days it is painted a bronze color called “Eiffel Tower Brown”.

Today, the Eiffel Tower is the most popular paid attraction in the world, with about 7 million visitors each year. It has been the inspiration for replicas(复制品) and imitations around the world. No longer considered an eyesore, the Eiffel Tower is an icon of France and is inside the World Heritage Site that includes certain parts of Paris.

6 . 2000 years ago, the most powerful army in the world belonged to the Romans. They conquered (占领) almost all of Europe, and parts of Asia and Africa. Life in the army was harsh. And many of the soldiers long for the comforts of home. They wanted to get married and set up families. The emperor whose name was ClaudiusⅡ, grew worried that his army was growing soft. And so he made a law that no soldier was allowed to get married.

By that time, many of the Romans were Christians (基督徒). And one of their leaders was a bishop, called Valentine. He believed that if a man and a woman fell in love with each other, they should get married. And so he decided to let soldiers get married in his church, even though it was against the law. The soldiers’ weddings were meant to be kept secret. But as you know, all secrets are hard to keep. And soon the word got out. Valentine was arrested and brought before the emperor who demanded that he stop helping soldiers to marry. When he refused, the emperor sentenced him to death.

While Valentine was in prison, the Jailer’s daughter used to bring him food. She was a young blind woman. She and Valentine used to spend long hours talking to each other. And soon they fell in love. One day, Valentine put his hand through the bars of the cell and touched the lids of her closed eyes. When she opened them again, she could see. It was a miracle. The love story didn’t continue. Unfortunately, Valentine’s execution was set for February 14th.

This took place in the year 270. And ever since, people have observed the day of February 14th called Valentine’s Day, in honor of this brave bishop.

7 . The Masai(马赛人) are continually trying to keep their own ways in an increasingly modern world. They live along the border of Kenya and Tanzania in East Africa, moving their homes from time to time to follow their cattle, the source of their livelihood. They rely on their cattle in many parts of their life. They like drinking the cows’ milk.

They don’t kill their cattle for food. But if a cow is killed, the parts of its body are used to make containers, shoes, clothin,   ropes, bed coverings and so on. Not all of the men have cows. The more cattle a man owns, the richer he is considered to be. A man who owns 50 or fewer cattle is considered poor. Rich men have a thousand or more. The cattle, though owned by the man, are considered to belong to the man’s entire family. The family names the cattle and can recognize each animal’s special voice.

The Masai men have become known as warriors(勇士), protecting their cattle against other wild animals. They wear their red long hair. Most women often take care of their children, cook food, clean clothes and make clothing at home. They also make necklaces dresses and headdresses. A few women can also become authorities once they are powerful enough. They speak a language called Maa.

The houses of Masai made from sticks and grass, which are held together with a mixture of mud, are not very firm or safe. These plain houses with some basic supplies are built in a circle and make up a Masai village. They are not meant to last long since the migration(迁徙) of the cow population means that the Masai move as well. In the meantime, in order to prevent animals from entering, they also form a wall of branches. The whole setup is to protect the cattle, which sleep at night in the middle of the village. They seem to live a natural and self-sufficient life but lack modern civilisation.

9 . Fossils are well preserved remains, impressions, or traces (痕迹) of animals and plants that lived long ago. Paleontologists (古生物学家) divide fossils into two main groups. Some fossils, called body fossils, show the structure of the plant or the animal. They form directly from the remains of plants and animals. Other fossils, called trace fossils. They record signs of animal or plant activities, such as walking, feeding, scratching, or even resting.

Most animals and plants don’t become fossils after they die. They break down into little bits or may be eaten by other animals. But some remains get buried too fast, avoiding those things happening. An animal might die near a body of water and sink to the bottom, where its remains get covered in sediment (沉积物). As sediment builds up, mineral-rich water seeps into the remains, leaving minerals in the tiny spaces of the bones and even replacing the original bones. The new minerals react with those in the animal’s remains and then harden into fossils.

Most fossils are buried deep in the Earth. As the Earth’s surface changes, scientists can dig up new fossils and learn more about past life and the Earth’s history. In rock that formed before a certain time, roughly 2.8 million years ago, scientists will not find human fossils.

Fossils are our keys to understanding prehistoric life and the Earth’s history. By studying fossils, we learn about a great variety of plants and animals that lived in the past. We can know what they looked like, how and where they moved and what they ate. By comparing fossils from different time periods, we can track the evolution of a species, see how it adapted to changes in its environment, and understand more about the climate and environment where the fossils were buried.
