5 . 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.

6 . Blind people have long desired for brightness, but scientists don’t have the technology. To bring that one step closer to reality, Zhiyong Fan, a materials scientist of the Hong Kong University of Science and Technology, developed a new artificial eye recently. The device, which is about as sensitive to light and has sharper vision and a faster reaction time than a real eyeball, may outperform human eyes.

The human eye owes its wide field of view and clear eyesight to the retina (视网膜) — an area at the back of the eyeball covered in light-detecting cells. The design for a new artificial eye is based on the structure of the human eye and uses a friendly light-sensitive material. At the back of the eyeball, an artificial retina is lined with Nan scale light sensors (纳米级光感器). Those sensors measure light that passes through the lens (晶状体) at the front of the eye. Wires attached to the back of the retina send signals from those sensors to the processor, similar to the way nerve networks connect the eyeball to the brain.

“In the future, we can use this to replace damaged human eyes,” says the lead designer. In theory, this artificial eye could see more clearly than the human eye, because the artificial retina contains about 460 million light sensors per square centimeter while a real retina has about 10 million light-detecting cells per square centimeter. Besides, the artificial eyeball records changes in lighting faster than human eyes can — within about 30 to 40 milliseconds, rather than 40 to 150 milliseconds. Although its 100-degree field of view isn’t as broad as the150 degrees a human eye can take in, the device can see as well as the human eye in poor light.

Hongrui Jiang, an electrical engineer at the University of Wisconsin, though, thinks engineers need a much more practical and efficient way to produce vast series of tiny wires on the back of the artificial eyeball to give it superhuman sight, which is super hard to achieve.

8 . When 19-year-old Emily Bhatnagar from Maryland, USA, found out her father had stage four thyroid (甲状腺) cancer, her response was a little different than you might expect. To honour her father, who she also describes as her best friend, she decided to start a book drive called For Love and Buttercup, collecting books for kids with cancer.

“It was very much an overnight idea,” she explains. “I posted a message on an app called Nextdoor asking my neighbours for used book donations. I was only expecting a few here and there, but the response was truly incredible, and it was just the push I needed to co-exist with my grief rather than letting it consume me.

“It was absolutely heartbreaking to watch my dad go through cancer and see him lose a little bit of himself each day, but the book drive allowed me to develop a newfound sense of purpose combined with an even greater sense of compassion (同情) to help others in any shape or form. I wanted to help kids. They’ve always held a soft spot in my heart.”

Using tips she earns from working at her parents’ bread shop, Emily has bought many books out of her own pocket. In addition, she receives donations through her Amazon wish list, which can be found in the bio of the book drive’s Instagram account.

Emily and her older brother spent a whole summer driving around town, loading boxes of books into their car. “It was such an honour knowing people have carried these books all their lives through generations, and they wanted to gift it to my cause.”

The project has seen huge success, with For Love and Buttercup donating over 15,000 books and being recognized by The Washington Post, Forbes, The President’s Volunteer Service Award and Lady Gaga’s Born This Way Foundation.
