4 . Mia Samolinski attended the same school as Anthony Zhongor, an 18-year-old freshman, but the two had never met. That night, their paths crossed in the most remarkable way.

Mia had just gotten into her car and was about to drive away, but she hit the gas instead of the brakes. Security footage (录像) shows the car rushing over a sidewalk, hitting a trash can, and then plunging (突然前冲) into the dark, cold water of the bay in just a few short seconds. People rushed to look in the water, but only one person jumped in after Mia, and it was Anthony.

“She went pretty deep in there,” the teenager recalled. “She was striking the door and the window, trying to break the window, of course, and that got me nervous and scared for her, so I just took my clothes off and went into the water.”

Mia’s car began to sink rapidly, but she couldn’t get the doors or windows open. Anthony tried to get the doors open from the outside, but couldn’t quite manage it. As the seconds ticked by, the teenage hero realized he could use his own body weight to push down the heavy front end of the car, making the back end stick out of the water. Mia climbed into the back and managed to escape through the rear hatch (后备箱盖). She and Anthony swam to the shore together. As soon as they were safe, tearful Mia thanked Anthony sincerely for saving her.

Like so many heroes, Anthony did not set out to save a life that night. But he was in the right place, at the right time. “It doesn’t matter who it was, he or she was suffering,” he said, “I couldn’t watch anybody suffering in front of me.”

5 . Since the Endangered Species Act (ESA) was passed in 1973, it has helped hundreds of species avoid extinction in the United States. The strong conservation policy has been used as a model in other countries. But it’s not as successful as it could be, a new study finds.

Researchers have discovered most species are not being protected until their numbers have become so low that their chance of recovery is slim.

“The ESA is an incredibly powerful, ambitious law for protecting our endangered wildlife. Yet, for decades, the agency primarily responsible for operating the ESA — the US Fish and Wildlife Service (USFWS) — has been starved of resources,” lead author Erich Eberhard says.

“As a result, we are very slow to give species the protection that they deserve. We typically wait until species are extremely rare and thus at extreme risk of extinction, and then, when a species is finally listed, the USFWS is straining its resources to try to recover it.”

In 1993, a study found that few species received protection under the ESA until their populations became very small. For the new study, researchers repeated the methods used in the earlier research to see whether protections have become better since the problem was first noted. They also looked at trends in “wait times” — the amount of time between when a species is identified as potentially needing protection and when it actually receives protection under the ESA.

“Our analysis suggests that, in the nearly 30 years since attention was first brought to this problem, we have not become more active in protecting endangered species,” says Eberhard.

The researchers found that the population sizes of species when they first became protected under the ESA are not statistically different from those in the 1993 study. They also discovered that there are long wait times between when a species is identified as likely needing protection and when they actually receive them.

“I can say that our study paints the current state of the ESA as a bit of cautionary (告诫的) tale for the strong conservation policy,” says Eberhard.

6 . It’s known that reading is good for a child’s vocabulary and literacy skills, teaching them math or science concepts and helping them learn history. Apart from those, reading has another benefit. Have you read a story and felt tears well up because of a character’s suffering? If so, that is because you have empathy (共鸣) for the character — and empathy can be learned through various fictions. “It’s a magic eye that sees into other people’s hearts,” explains author Cressida Cowell.

Research shows that human brains react differently to stories and facts. “Many more areas of your brain light up when you’re enjoying a story,” explains Miranda McKearney from EmpathyLab, an organization that builds empathy through reading. “Your brain thinks you are in the story… This means you experience the characters’ thoughts as if they are real.”

Empathy helps you to read people’s emotions and work out the best way to respond. This skill, called emotional intelligence, can make it easier to communicate and connect with people. Research has shown that building empathy can lead to greater kindness and tolerance. One study found that children who read the Harry Potter novels — which tell stories about humans fighting against the evil — were less likely to behave unfairly towards powerless groups including refugees (难民).

This theory has been put into practice by St Michael’s Primary School. After reading The Boy at the Back of the Class — a story about a boy who is a refugee escaping from the war — students in that school were inspired to do a 10-mile walk for the non-profit organization Refugee Action. Their empathy also spurred them to raise £1,000 for people who were forced to leave their homes because of war.

Reading encourages children to empathise with others, which could potentially lead to several beneficial learning outcomes, new research suggests. For society to develop, creative, communicative and empathetic individuals really matter.

8 . Nobel Prize-winning theoretical physicist Frank Wilczek has been honored with this year’s Templeton Prize. The award recognizes individuals whose life’s work brings together science and spirituality.

Wilczek is known for his research into the laws of nature. In a statement, the John Templeton Foundation said his work changes “our understanding of the forces that govern our universe.” It said he used physics to address “the great questions of meaning and purpose pondered by generations of religious thinkers.”

John Templeton created the prize in 1972. It is one of the most highly valued prizes at more than $1.3 million. Past winners include Jane Goodall, Mother Teresa and Archbishop Desmond Tutu.

Wilczek told The Associated Press, “It’s a company I’m very glad to join in.” He added, “It’s encouragement in a direction that I’ve really only taken up in a big way quite recently… which is thinking about not just what the world is and how it came to be this way but what we should do about it.”

Over a long career, Wilczek had many successes. He won the 2004 Nobel Prize along with David J. Gross, and H. David Politzer for their 1973 research explaining the unusual properties of the strong force. Wilczek is currently a physics professor at the Massachusetts Institute of Technology, Arizona State University and Stockholm University. He is also the founding director of Shanghai Jiao Tong University’s T. D. Lee Institute. He has also written several books that are informed by science but look into spiritual and philosophical questions.

Heather Dill is the Templeton Foundation president. In a statement, she said, “Like Isaac Newton and Albert Einstein, he is a natural philosopher who unites a curiosity about the behavior of nature with a playful and profound philosophical mind.”

9 . For some people, nothing beats a long walk on a sandy beach. But there’s no denying that it’s not as easy or as fast to get around on the beach as it is on a road or a sidewalk. But why is it so hard to walk on sand?

The problem with sand is that it’s soft; you “sink in” at each step. This forces you to use 2.1 to 2. 7 times more energy with every step you take. Another idea is that people walk more difficultly on soft than they do on hard surfaces, a study found. The researchers compared how people walked on foam (沫) and hard surfaces by analyzing the forces under their feet and how much oxygen each person consumed. They found that walking on soft surfaces, such as sand, mud and snow, caused people to take longer steps — actions that use more energy than walking on a hard surface.

But as experienced beach walkers know, there’s a way to make it easier to walk on sand: Just add water, When sand is wet, it becomes more compact (紧密), and walking on it is more similar to walking on hard surface. In other words, it’s much easier to cross a beach by walking along the shoreline, where the waves roll in and out. This is a balance though; too much water could make the sand soft once again. If water isn’t an option, there is another way to make walking on sand easier — increasing your surface area. This could be accomplished by wearing shoes.

Although it’s more difficult, there are some good reasons to exercise on sand. The impact forces are lower on sand than on hard surface. Research suggests that walking across sand is much easier on your joints (关节) and muscles, especially compared with an unforgiving surface such as concrete (混凝土). This means sand is a better surface for helping athletes recover more quickly from workouts.

10 . With the Forbidden City and Jingshan Park to its east, Zhongnanhai to its south, Beihai Park, also known as Northern Sea Park, is one of the oldest, largest and best-preserved ancient imperial gardenst (皇家花园) in China located in the center of Beijing.

Beihai Park is said to be built according to a traditional Chinese legend. The story is that once upon a time there were three magic mountains called “Penglai”, “Yingzhou” and “Fangzhang”. Gods in those mountains had a kind of medicine which would help humans gain immortality (永生). Consequently, many emperors constantly sought those mountains. I For example, Emperor Qin Shihuang had sent people to look for the magic mountains but they failed. Emperor Wudi, the fifth emperor of the Western Han Dynasty did similar things.

It was believed that different mountain-water combinations in ancient Chinese architecture led to totally different effects. So from then on, almost every emperor during the succeeding dynasties would build a royal garden with one-pool-with-three-hill layout near his palace. Beihai Park was surely built after this traditional style: the water of Beihai with Zhongnanhai is the Taiye Pool; the Jade Flowery Islet, the island of the Circular City and the Xishantai Island represent the three magic mountains.

Actually, Beihai Park was initially built in the Liao Dynasty (916-1125) and was repaired and rebuilt in the following dynasties including Jin, Yuan, Ming and Qing. The large-scale rebuilding in the reign of Emperor Qianlong of the Qing Dynasty (1644-1911) generally established the present scale and pattern. In 1925, it was first opened to the public, attracting hundreds of thousands of visitors from all over the world every year.

It is enjoyable to walk around the various scenic areas in Beihai Park. There are many places to visit, including the Bai Ta, Five-Dragon Pavilions, Nine-Dragon Wall, Yong’an Temple and so on. There is also a classy restaurant called Fangshan Restaurant where the Empress Cixi once dined.
