Below is a list of women who changed the world when they were young girls and teens.

Mary Shelley

English author Mary Shelley was just 18 years old when she wrote Frankenstein, which many credit as the origin of science fiction. Thus, Shelley has been called “the teenage girl who invented science fiction.”

Alexandra Scott

Alexandra Scott was diagnosed with a form of cancer shortly before her first birthday. When she was just 4 years old, she set up her first lemonade stand in her front yard to raise money for childhood cancer research. Inspired by her story, people around the world set up their own lemonade stands to raise money for her cause. By the time she died in 2004, she had raised S1 million. Her family continues her legacy (遗志) through Alex's Lemonade Stand Foundation.

Yuanyuan Tan

Chinese ballet dancer Yuanyuan Tan started representing her country in international competitions as a young teen. At 17, she became the youngest ever principal dancer at the San Francisco Ballet, as well as the first Chinese dancer to earn that title in a major Western company. She gives talks around the world, inspiring young dancers to follow their artistic dreams.

Bindi Irwin

Bindi Irwin carried on her father Steve Irwin's conservation legacy following his death in 2006. When she was 8 years old, she launched “Bindi the Jungle Girl” to encourage more kids to get interested in animals and wildlife conservation. She has continued to make TV appearances, published books and furthered her father's causes.

About 50 feet from shore, two brothers were fighting for their lives, their mouths barely able to stay above the water. Thick fog made it difficult for beach goers to see the guys, but the screams were unmistakable and every second counted. The brothers, aged 15 and 20, were wearing shorts and T-shirts, unsuitable for a November day, let alone the 50-degree water. Keven Harder, a supervising ranger, told the North Coast Journal that swimming in such a temperature “will take the fight right out of you.”

Luckily, four surfers in wet suits were nearby. Narayan Weibel, Spenser Stratton, and Adrian York, all 16, along with Taj Ortiz-beck, 15, were on their surf boards riding on waves when they heard the cries. They turned and saw two bobbing heads and four flailing arms. “We looked at each other and knew they were about to drown,” Weibel said.

Weibel, Stratton, and Ortiz-beck paddled toward the distressed swimmers while York headed to shore to call 911. As the surfers drew close, the brothers were struggling. “It was pretty stressful, but there wasn't any time to think about it,” Ortiz-beck said. He pulled up alongside the younger brother. Grabbing him under his arms, he raised him up onto the board. Stratton and Weibel, meanwhile, were straining(竭力)to help the elder brother. He was large, about 250 pounds, and panicked. Fortunately, York arrived in time to help get the elder brother atop the second board. The surfers then paddled several minutes through rough water to the medical help waiting onshore. The brothers were scared but fine.

“When we get a call like this one, it's usually too late by the time we get there,” said Dillon Ceavenger, the first responder. “I can't say enough about what these boys did. They were willing and prepared to risk their lives.”

The world has been extremely impressed by China's high-speed trains that cross the country by the hundreds in all directions every day, but in one corner of this vast land is a gentle reminder that life was not always this fast.

Those fortunate enough to travel to Jiayang in Sichuan province will find railway carriages dragged by steam locomotives(火车头), among the last steam trains operating in China and still running every day. First used to transport coal from Jiayang Coal Mine 62 years ago, today they transport local farmers and their produce to market and serve as a tourist attraction.

“In the early days of the railway, farmers headed for the farm produce market sitting beside coal,” said Liu Chengxi, the Jiayang official in charge of the trains. “As coal production has stopped, the trains are now exclusively(专门地)for farmers and tourists.”

The narrow railway, only 76.2 cm instead of the standard 144 cm, stretches for 19. 84 km, with the trains reaching a top speed of 20 km/h.

A one-way ticket costs 5 yuan for seated passengers and 3 yuan for standing passengers on the ordinary trains regardless of whether they are travelling empty-handed or with animals or vegetables. But Li Cuirong, who has worked as a train dispatcher(调度员)for more than 20 years, recommends tourists pay 80 yuan for a sightseeing train, as the carriages, which have 37 seats, are more comfortable and air-conditioned. A one-way trip takes about one and a half hours.

The scenery is dramatic as the train winds through the mountain, passengers can view chickens and geese wandering among the orange trees and butterflies dancing over the fields and ponds.

Rob Dickinson, a steam train lover from the United Kingdom, has ridden the trains twice. He hopes the narrow line can last long enough for him to find the time to get back again.

A latest study on people who eat red meat has found they have higher risks of heart disease and early death. The finding goes against other recent research that suggested removing meat from one's diet has few health benefits. The two opposing findings can make it difficult for people to make sense of what can seem to be conflicting messages on food.

Duane Mellor, a dietician at Aston University, and other researchers say that after examining research on the subject, moderation may be the best way forward. “In this case, eating a certain amount of meat, including red meat, is likely to be safe,” Mellor said. “However, in the interest of health, reducing meat intake to the recommended less than 70 grams per day would be sensible.”

A researcher with ties to the meat industry published a report on the subject in 2019, saying that people should not reduce the amount of red meat they eat. Some experts criticized the findings because they were in conflict with dietary advice from international agencies.

The latest study found that eating two servings a week of red meat or processed meat was linked to a 3% to 7% higher risk of heart disease and also a 3% higher risk of all causes of death. Norrina Allen, a co-leader of the latest study, said the health risk is small but people should try to change their diet. “It's a small difference, but it's worth trying to reduce red meat and processed meat.” She added that eating red meat is also regularly “linked to other health problems like cancer.”

The World Cancer Research Fund says red and processed meat may cause cancer. It recommends eating red meat with an upper limit of 500 grams cooked weight per week-and “little, if any” processed meat. They said on average, adults should reduce the amount of meat they eat by 50% and they should eat twice as much nuts, fruits, vegetables and beans.
