【推荐1】Getting into science is often difficult for some kids, It’s something Ahmed Muhammad learned quickly while babysitting his niece and nephew.

Muhammad is an 18-year-old senior from California. who attends Oakland Tech High school. One day he asked his niece and nephew if they wanted to do science, and he was upset by their reaction.

“Whenever I babysit them, we do things like playing chess, playing video games, or watching TV or whatever. When I tried to do science with them, they were like, No, I hate science. I’m bad at it.” It was that moment that fueled Muhammad to create his nonprofit called “Kits Cubed” with a mission to introduce kids to science through fun, affordable and accessible means.

“I went into my room and I pulled out some science books. Then I went online and did some research and was able to design some science experiments for them to do at home. The materials were composed of fairly cheap stuff we have around the house, and they loved it” Muhammad said.

After witnessing their joy, he realized other children could benefit from it as well. “Having noticed the long-standing absence of science experiments in our school, I really feel like well need some science kits in the hands of kids,” Muhammad said.

That’s when he took the $200 he had saved to create a website and began creating science kits to sell, and eventually donated the earnings to kids in need. “I had enough money to make the website and enough to put together like 10 or 15 kits. My initial goal was the joy that my niece and nephew felt. I wanted it to get to as many kids as possible,” Muhammad said.

Muhammad, who has been accepted to Stanford University, is just thrilled he was able to help change his niece and his nephew’s opinion of science while inspiring others as well.

【推荐3】The Shenzhou XVI members completed their first spacewalk on Thursday, equipping and adjusting (调整) camera devices outside the Tiangong space station, according to the China Manned Space Agency.

This was the 13th spacewalk carried out by Chinese astronauts. Mission commander Major General Jing Haipeng and spaceflight engineer Colonel Zhu Yangzhu conducted their eight-hour spacewalk and returned to the Wentian science module (舱) at 9:40 pm, the agency said in a news announcement. Professor Gui Haichao, the third member of the crew (全体工作人员) and the mission’s science payload specialist, stayed inside the space station to provide support, the news release said.

During their spacewalk, Jing and Zhu finished a series of tasks, such as fixing a support structure for an expected camera outside the Tianhe central module and unlocking and moving two expected cameras outside the Mengtian science module. Jing, who was on his fourth spaceflight, took part in a spacewalk for the first time. During the Shenzhou W mission in September 2008, which was his first spaceflight, Jing stayed inside the spaceship to assist his fellow members, Zhai Zhigang and Liu Borning, who completed China’s first spacewalk.

On Thursday afternoon, Yang Yuguang, a senior space industry observer and vice-chair of the International Astronautical Federation’s Space Transportation Committee, had said that despite this being Jing’s first spacewalk, he should have no problem in completing the operation because he is an experienced astronaut and has been mission commander three times. “Jing has known how to deal with difficult tasks and has rich experience in controlling challenging or risky situations, which will help him when he carries out the spacewalk,” Yang said.” Zhu was a teacher at the Space Engineering University before he became an astronaut, so he has expert knowledge in spacecraft engineering and operations,” Yang added.

The Shenzhou XVI crew arrived at the Tiangong space station on May 30 to take over it from their Shenzhou XV crew, who had stayed there for six months.

【推荐1】Nearly a week after Stephen Hawking passed away, people even in remote parts of the globe showed up in memory of this great British scientist. Mr. Hawking, best known for his study of black holes, is respected for not allowing a physical disability to limit his mental brilliance. Yet in a sign of the state of humanity, he is also being held up as a hero for humble and intense curiosity, not just for the truth about the physical universe but for universal truths.

In 2017, a Texas-based data company called Global Language Monitor found “truth” to be the “word of the year” among English-speakers. A debate over the nature of truth “is currently quite fashionable,” the company’s analysis found. Besides, two runner-up words were “narrative” and “post-truth.” And in a January report about “truth decay (衰败)”, the RAND Corporation, a research organization, found the loss of trust in key institutions has left “people searching for new sources of credible and objective information.”

In countries with a free press, journalists have gathered to fact-check comments by politicians. Harvard University now offers a free one-hour online course to help people “better distinguish good information from bad” in hopes that they will not “share the bad.” Tech giants such as Facebook are being forced to fix truth filters (过滤器) on their online platforms. A report this month for the European Commission says that the online sites “are becoming increasingly important as both enablers and gatekeepers of information.” They should reveal how their algorithms (计算程序) select news items, the report stated.

Many nations have come to see honest information as strategic wealth. “Truth matters”, says Mike Pompeo, Secretary of State. “Relying on Twitter feeds and news reports will prove totally insufficient when policymakers have to make some of the most difficult decisions they face.”

Giants of scientific discovery such as Hawking have long been role models for seeking truth beyond their profession. “In recent years I realized that Hawking has become a symbol for mankind,” says physicist Bobby Acharya. “People looked to him for reason and truth.” The tribute rolling in for the man is actually a widespread desire for light over darkness, for truth over all the “black holes” of misinformation campaigns.

【推荐3】“I want to work full-time in China, honey.” An overseas call awakened the wife from sound sleep. “Why?” asked the wife with surprise, in a drowsy (昏昏欲睡的) voice, from the other side of the ocean.

In the United States, he had a great future ahead. At the age of 36, he became the youngest professor in the history of the Department of Molecular Biology at Princeton University, for his academic achievements. At 40, he became a tenured (终身的) chair professor at Princeton.

When everything seemed perfect and admirable to others, he firmly decided to say goodbye to Princeton University, to an affluent life in the United States, and return to China.

The news spread explosively. Many expressed confusion, many persuaded him, many made fun of him, and still many waited to have a good laugh at him.

He said patriotism is the plainest feeling of a person. Who doesn’t love his motherland, after all? In his heart, the American dream is already something past; the Chinese dream is rising.

After returning to China, he devoted all his energy, worked like crazy, and determined to do something big. He formed a life science research team. Every day, he works 12 to 16 hours at his laboratory.

He is Shi Yigong, nicknamed “Da Niu” (someone with extraordinary achievements) by Tsinghua students. His given name, Yigong, comes from an idiom that means “devoted to public interest whole-heartedly”. “So far as I’m concerned, awards are of no special meaning.” Shi says calmly.

In his 18 years of study in the United States, he never forgot his Chinese dream. In the next 18 years, the Chinese dream will be more beautiful and greater by the efforts of Shi Yigong and the likes of him.
