1 . After decades of exploring the moon, a dramatic vision is finally becoming reality. The Guardian recently reported that a project called Lunar Codex is planning to send and store over 30,000 works on the moon from artists, writers, filmmakers, and musicians from over 150 countries and regions. The goods to be stored range from novels and paintings to music, films，and even soil from Earth.
In fact, this is not the first time that people have tried sending human legacies (遗产) to outer space. In 1969, the Apollo 12 mission carried a ceramic piece with drawings. In 1971, the Apollo 15 staff left a sculpture to honor those who had died in space exploration. What’s more famous is the Golden Record carried by spacecraft Voyager 1 and 2 from NASA in 1977, which contains human language, music and images. For example, a piece of Chinese guqin music, called Flowing Streams was included in it.
Although we don’t know who determines which symbols of human legacy get sent out to space in most projects, it’s obvious that the criteria keep changing. In the past，space heritage products only focused on space-related works; but gradually, more human-related contemporary goods which held great importance in their respective eras have been added to the list. In the Lunar Codex, films, diverse art and literary works produced by women, disabled artists, and even AI have been collected for the first time to be sent to the moon.
These changing criteria also leave space for ordinary people to imagine and think. Many people are now trying to store their DNA information digitally. Will people be able to find even more surprising and inventive ways to preserve their legacy in the future? Only time can tell.

2 . In today’s digital era, social media users are increasingly coming across fake news online. This leads to the pressing issue: What causes people to fall for misinformation on the Internet?
According to researchers at the Penn State College of Information Sciences and Technology, users can easily fall into an echo chamber (回声室)—a sort of virtual space where users consume only one-sided news, eventually distrusting any opposing views. “We all tend to agree with the group opinion. Hence, people naturally get together with others who hold the same opinion,” said Dongwon Lee, one of the researchers. “But if you’re not cautious, there is a high risk of falling into an echo chamber.”
To prevent this phenomenon, the researchers have crafted a novel tool, a game named ChamberBreaker, to help players resist echo chambers and reduce the rate of fake news spread. The fundamental approach employed by ChamberBreaker centers around a decision-making procedure that mirrors the creation of echo chambers. In ChamberBreaker, a player is tasked with trying to have community members fall into an echo chamber. To begin, the player is randomly assigned a situation that focuses on a health, political or environmental issue, and is presented with six pieces of news on that topic. Then, the player selects news that could cause the other members to fall into an echo chamber while at the same time maintaining their trust. If successful, the community members will fall into an echo chamber and the player will witness the resulting negative effects on the community.
After developing ChamberBreaker, researchers tested it with over 800 subjects to see if it raised awareness of echo chambers and changed news consumption behaviors. The researchers found that those who played ChamberBreaker were significantly more likely to state their intention to observe online information from more diverse perspectives and showed an increased awareness of the echo chamber phenomenon.
Ultimately, the researchers hope that their methodology can excite a greater interest in the scientific and scholarly study related to information consumption. The application of tools like ChamberBreaker, which focuses on fostering analytical reasoning, may lead us towards a more informed online community.
