1 . On July 14, 2017, Maryam Mirzakhani, Stanford professor of mathematics and the first female winner of the Fields Medal in Mathematics, died at the age of 40.

The news was especially hard-hitting for a generation of younger academics who have always held Maryam as a role model whose example is helping redefine women’s status in science and especially mathematics. What was fun was that Maryam always tried to avoid the media’s spotlight. Her modesty (谦虚) and simplicity despite being the first woman to gain such high status in the world of mathematics — winning what’s often called the “Nobel Prize of math” — stood out to those who knew her.

Maryam originally wanted to be a writer, a passion of hers that never faded away even during her postgraduate studies. However, she found an even greater joy in how rewarding it felt to solve mathematical problems. As a student, she was the first female member of Iran’s national team to participate in the International Math Olympiad (IMO), and she won two gold medals in two years — still a record.

She received her bachelor’s degree in Iran and later studied at Harvard. In 2014, Maryam was recognized with the Fields Medal, the highest-ranking award in mathematics. Her work focused on curved surfaces like spheres (球体). Her achievements have applications in other scientific fields including engineering and material science. Unfortunately, at that time she was already tackling the breast cancer.

Maryam’s legend (传奇) may continue to grow after her early death. Still only 20 percent of full-time math teachers at U. S. universities are women. The example of a woman who rose to the top of this still very male field may help inspire math’s next generation.

In the same way people think of Marie Curie or Jane Goodall as scientific pioneers, Maryam Mirzakhani will go down in history as a trailblazer as well as a mathematical genius.

2 . Animal rescuer and cinematographer Douglas Thron’s passion for animals began when he was a little kid and he started rescuing orphaned baby animals. When he grew up, he worked as a cinematographer for shows like Discovery Channel’s “Shark Wee”. But Thron said a fire in California “pushed” him to rescue animals, using his cinematography skills well.

At the time, Thron was working as a cinematographer filming a man who was rescuing cats after the fire using an infrared (使用红外线的) handheld camera. The camera uses heat to detect the animals at night. Thron and the man talked about how incredible it would be to put one on a drone (无人机) to detect animals easily. “The animals’ body temperature will flash on the screen and you can pick them out among the rubble (瓦砾),” explains Thron.

The first animal Thron ever rescued was a dog in the Bahamas after a category 5 hurricane hit there. Thron tested out putting an infrared scope on a drone and found the dog exactly in the middle of the huge rubble pile where hundreds of houses had been destroyed. “I flew the drone over and I found him. I was able to rescue him,” he says.

“My dream is to one day have a large animal rescue farm where I can train others on flying drones and make infrared drones as popular for rescuing animals as helicopters are for rescuing people after a disaster,” he says.

3 . On many travelers’ lists of things to do before they die, you’ll find “See the northern lights” written down. Rightfully so these lights are one of nature’s most jaw-dropping views.

In Sweden, the northern lights usually appear from late March or early April. Your best chance of catching a glimpse of them is on cold winter nights when the sky is clear, dark with little to no moonlight, and cloudless. You need to be away from city lights and go to the countryside. For those willing to brave the cold on winter nights, here are some of the best locations.

Abisko National Park

Abisko Natinal Park is a main location. The scientifically confirmed “blue hole”, a piece of sky over the Tornetrask lake that usually remains clear despite cloudy weather nearby, gives Abisko its own microclimate (局部地区气候), which is suitable for catching the lights.

Jukkasjarvi

The village of Jukkasjarvi only has about 550 people. But don’t let the small population size fool you: Jukkasjarvi owns the world’s first ice hotel and is one of the best places to view the northern lights. The ice hotel organizes guided tours for guests to the Esrange Space Center. There you can eat at a camp outside and see the Arctic winter sky for aurora borealis (北极光). Or why not try to get closer to the northern lights and watch them through an aeroplane window? The ice hotel arranges flights for the amazing northern lights experience.

Gallivare

You can drive a snowmobile to the mountain top in Gallivare for a private light show, or head a few kilometers to nearby villages to watch those lights shining across the dark winter sky. But remember if you do get the chance to see the northern lights in person, never whistle to them. According to ancient Sumi fairy, it brings you bad luck.

4 . Sumiel, a 71-year-old, was no stranger to the struggles of kidney (肾) disease. He was on the transplant list (移植名单), but no matches had yet _________. So he continued with his treatments at a medical center 30 miles from home.

One day, he took a taxi home after his _________ with the doctor. As they set out on the 40 minute _________ to Sumiel’s home in Salem, he and the driver, Letts, got to _________. Sumiel mentioned that he’d enjoyed _________ and helped others in his community before. But he was doing less these days because the treatments left him_________ tired. Then Sumiel revealed that he was _________ a kidney giver. Letts said, “I’d like to see if I could be a _________ to give you a kidney.” Sumiel agreed, though he didn’t _________ much of it as they kept driving.

Letts was __________ to his word. He got in touch with Sumiel just a few hours later, and by the next week, Letts had__________ the kidney transplant program. After a month’s long screening __________ — including an interview, sharing medical records, and testing the __________ were: Letts was an ideal donor, and he and Sumiel were a perfect match.

Fourteen months after they ended up in the same taxi by __________, Sumiel and Letts had their surgeries. It was a __________. They kept in touch and looked forward to the day they could reunite.

6 . We’ve got a list of teen scientists from a variety of fields.

Jack Andraka

Jack Andraka created a biosensor for cancer that he says is 168 times faster, 26,667 times less expensive and 400 times more sensitive than technology nowadays.

He’s the youngest person to have spoken in front of the Royal Society of Medicine.

Taylor Wilson

Taylor Wilson was the youngest person to achieve nuclear fusion (核聚变). He was inspired by The Radioactive Boy Scout, a novel in which a kid tries and fails to build a nuclear reactor.

Taylor thought he could do better. Long story short, he wanted to build a small nuclear reactor. And he did it at the age of fourteen. He received a Thiel Fellowship, which gave him $100,000 to work on his own research.

Sara Volz

Sara Volz performed experiments in which she grew algae based on their oil output for the purpose of growing them as biofuel (生物燃料). This research is especially important as the world continues to search for a way to lessen our dependence on non-renewable energy. She won the top prize of $100,000 in the Intel Science Talent Search.

Daniel Burd

Plastic usually takes thousands of years to decompose (降解), but this high school student Daniel Burd managed to do it in three months.

In an experiment, he mixed plastic bags and a special kind of dirt together, and found that they did decompose faster. He then performed tests to find the bacteria responsible for decomposing the plastics.

His solution only produces water and small amounts of carbon dioxide. He says it could easily be used elsewhere.

8 . The photographs that Scilla took as a 16-year-old girl on the streets of London in 1955 stayed largely in her album (相册) over the years. Scilla is now 83, and her self-developed black-and-white photos have been brought back to life after they were discovered by a teenage photographer.

Over the past year, Philip Loveday, 16, has been revisiting his grandmother’s path across the capital to carefully rephotograph the pictures. His journey through time with a camera has been especially moving, because his grandmother, Scilla, has Alzheimer’s disease (阿尔茨海默症) and has lost many of her memories.

Philip took new photos that looked like the ones Scilla took long ago, and put them in a new album. Each page of Scilla’s old album was copied and put in the new one, with Philip’s new photos on the opposite pages. Philip’s mother, Catherine Loveday, said Scilla had been happy with the new album, which had “put her back in her shoes” as a teenager.

Philip said his mother showed him the album she had found at her mother’s house. Greatly absorbed in how modern London would compare to the city photographed by his grandmother, Philip and his mother began to make trips into central London. During the trips, they had the idea of retaking the photos.

Some of the places are similar, like Big Ben. Others show how the city has modernized. Unlike Scilla’s view of St. Paul’s Cathedral from the Thames, Philip’s retake has the Millenium Bridge. When Scilla photographed the John Lewis store on Oxford Street, it was a one-storey building — now it has seven floors. Philip had to use his imagination to recreate other sights. Scilla has repeatedly returned to her new album since receiving it. Philip said: “It’s nice for her to see someone taking an interest in those photos and going back over them, and also good for her to connect her past to where we are now.”

9 . If you’re new to San Francisco, paying the city a visit, or simply looking for a new playground for you and your dog, here are four of the finest dog parks in San Francisco.

Corona Heights Dog Park

Often visited by residents from all over the city because of its nearness to the Randall Museum, Corona Heights Dog Park offers pets and owners breathtaking view after a steep hillside climb, and a fenced dog area that allows dogs to let loose without a leash (狗链). Owners will also enjoy the playground, tennis courts and basketball courts.

Dolores Dog Park

The grounds of Dolores Park once served as camps for those who were left homeless by the 1906 earthquake, but now are often visited by crowds of Mission District people. Four-legged friends can also wander about care free off-leash while making friends with other members of the doggie community.

Pine Lake Dog Park

Famous for its place as a rest stop for hundreds of species of birds to fly to and from warmer climates, Pine Lake Park is also prized by city dogs and their owners for their nice hiking paths, picturesque lake suited for swimming, and off-leash area on the park’s west end that lets dogs run free.

Buena Vista Dog Park

With a history of 146 years, Buena Vista Park is San Francisco’s oldest park. Dogs and owners with plus energy will love burning it on this park’s steep paths and winding staircases. Dog owners should have good control over their dogs, as it’s quite easy for dogs to get separated when going through Buena Vista’s many twists and turns.

10 . Hang your tongue out of your mouth while your eyes look upwards. Breathe loudly and use your hands to pull your head in every way. This is yoga (瑜伽) for your face.

Fumiko Takatsu, creator of the Face Yoga Method, has written six books on face yoga and has been practicing facial exercises for about 15 years. Takatsu, 50, said she came up with the idea of facial exercises after a car accident when she was 35 years old, which left her face out of its proper position. Around the same time, Takatsu said she began to notice signs of aging, but gave up using creams and beauty treatments after they became too expensive.

Koko Hayashi, 39, a face yoga instructor in Los Angeles, said she first heard of face yoga by discovering Takatsu’s work. Hayashi said she had a chin implant (下巴植入体) when she was 27 years old, but took it out because it misshaped her face. “That’s why I’m so interested in more natural beauty instead of plastic surgery (整形手术),” Hayashi said. Like others who practice facial exercises, Hayashi believes it can fix signs of aging and help reduce wrinkles (皱纹).

The question that often pops up when someone mentions face yoga is, “Does it actually work?” A study out of Northwestern University found that the exercises may help middle-aged women.

“This is a pilot study that suggests that there might be some factors of face exercise that can be helpful to at least certain patients in improving certain signs of aging,” said Dr. Murad Alam from Northwestern University.” But we need more studies to better understand exactly how much exercise is necessary to have any benefit, whether it works for men and women of different ages, and then how much exercise is needed to keep that benefit.”

Medical reporter Dr. Jennifer Ashton said that she is not sure whether face yoga works and that any benefits are most likely going to be up to the person trying it. “If you feel better after trying face yoga, it may be something you should keep doing,” she said.
