Whether from news reports or social media articles, you may know that 5G is coming.

5G is the 5th generation network. It is a new network after 1G, 2G, 3G and 4G. It can connect everyone and everything together. 5G networks will cover many cities in China soon. 5G means super-fast data speed. One can download a two-hour movie for fewer than 10 seconds, and it is making our lives more and more convenient.

5G will make self-driving cars possible. For safety, self-driving cars need super-fast data transmission (传输）to communicate with their nearby environment. 5G is just what makes self-driving cars achieve this. Even airplanes will become "smart" in the near future. Passengers will be able to use 5G networks in the air to connect to the Internet and can order for food and drinks.

5G will be a big help for students who take online classes. Many people live in poor areas in the world where there are no schools. But with 5G, this will change. Students all over the world will be able to see places like the Great Wall without leaving their rooms.

It will be also easier for doctors to treat patients remotely by 5G. It means caring for patients from far away.

The facts listed above are only a part of what 5G will make possible and popular. Just as in the early days of the Internet in the 1990s, few could see how it could change our life and the world. The same will surely be true of 5G. With 5G, many things do not seem like dreams any more. Now let's get ready to say goodbye to 4G and welcome the coming of 5G.

    "I have no special talent. I'm only passionately curious." This famous quote from Albert Einstein might tell the reason for his success. When Newton discovered gravity, and when Thomas Edison invented the light bulb, their curiosity was greatly satisfied. If they hadn't been curious, what a loss for humans!

There is a common truth that intellectual curiosity (求知欲）contributes to school performance more than intelligence. Some studies also show there are benefits of curiosity in improving the long-term level of learning and memory, and a lot of positive results are connected with curiosity.

It has been known that both animals and humans are willing to take a risk to satisfy their curiosity despite knowing that the result will remain unchanged. Despite there being different views on the reason for curiosity, most experts reach an agreement that like the way the stomach looks for food, our brain looks for knowledge. People and animals are eager to know things because getting that information means a reward.

An interesting thing is that our brain will release a pleasure-related chemical when it has been given new information, making seeking information much like eating — another pleasant activity. Researchers newly found that increasing the release of the chemical greatly increased the curiosity in animals. However, how exactly the chemical plays a role still remains a mystery.

Considering the present level of research on curiosity and the driving force of curiosity, including scientific curiosity, more research should be carried on in this field. It's safe to say that curiosity itself will help uncover curiosity. And remember even though the idiom says "Curiosity kills the cat", it ends with satisfaction bringing it back.

Huge Waves Destroying Arctic Ice Faster than Expected

Ice covers much of the Arctic Ocean. Some pieces of ice are huge, like moving islands. As temperatures have increased , however, some of the ice has begun to disappear. Scientists have discovered huge waves in the arctic waters.

The waves were discovered by accident in May, 2010. Scientist Aleksey Marchenko and his students set out on a trip. They wanted to study the icy waters.

The ship travelled east and stopped next to a large block of ice around 50 miles from the small island of Hopen. Marchenko prepared to lead his students out onto the ice.

"We were ready to go but when I went out, I discovered many cracks around," he remembers.

He decided to move the ship deeper into the ice to keep safe. The farther in they went, he thought, the harder the ice would become. As they pushed forward, however, the ship experienced small waves, and then bigger ones. Soon, the waves broke up the ice around the ship into thousands of smaller pieces.

Within an hour, Marchenko and his team saw a wave that was about 13 feet high. The ship's navigation system finally recorded the largest waves. They were more than 20 feet in height. The waves were so strong that they forced huge pieces of ice to jump up and down, breaking the ice into smaller pieces within just one hour. Scientists had never imagined that the process could happen so fast. The waves in these areas used to be small.

The speed and force of the huge waves there makes it impossible to know in advance when they are coming. That could be dangerous for navigators and local communities who are unprepared for huge waved or depend on sea ice to protect them. Wildlife like polar bears that depend on sea ice to live is also in danger.

Some scientists think people will soon see even bigger waves in icy waters. As waves break up ice, seas will be more open, waves will be stronger. There are stormy times ahead.

Marco Polo was born in Italy in 1254. When he was 17, he travelled along the Silk Road with his father, who wanted to do trade with the Chinese. Finally, they arrived in Beijing. They were guests at the Emperor's Palace. Although Marco was young, he was very clever and could speak four languages. The Emperor was impressed by him and they became friends. The Emperor asked Marco to help him and sent him to do many important jobs all over the country.

Marco was amazed by how great China was. He was impressed by the Emperor's Palace which he described as "The greatest palace that I've ever seen". The walls were covered with gold and silver and the hall was so large.

Marco was also attracted by lots of strange things in China. Marco was surprised to see Chinese people using paper money in the markets. In Europe, people paid for goods with gold and silver. He could not understand how people paid for food and valuable things with paper! He was also puzzled by the black stones people used to burn to produce heat. The black stones were coal, but Marco had never seen coal before!

After he served the Emperor for 17 years, in 1291, Marco returned to Italy. He had a lot of money then. A writer wrote down all the stories that Marco told him in a book called The Description of the World, which became one of the best-selling books in Europe.
