1 . Banff National Park is home to an amazing wildlife population. But the busy Trans Canada Highway that cuts through the park is a hazard to the lovely animals. To address the problem, Banff first put-up wildlife fencing on either side of the highway to discourage animals from entering the busy road. Then, since 1996, they’ve opened six wildlife overpasses and 38 underpasses to help the animals cross the highway in safety. I was fortunate to visit Banff’s Red Earth Overpass with Trevor Kinley, the project manager with Parks Canada. He told me that so far, they have documented 10, 000 safe animal crossings on this overpass alone. “ Some animals have learned how to use the crossings much more quickly than others. Black bears are the fastest learners, followed by deer. Wolves and lions take the longest to work out how to use them, ” Kinley said, laughing. “ But those animals that are slower to adapt are usually more capable and determined at figuring out the safest way to cross those overpasses and underpasses. ”

There is some criticism (批评) that channeling so much wildlife into a few bridges and tunnels is like making a trap for the animals, offering big animals an easy meal on either side. “ But research has shown that this is not the case, ” Kinley assured me. “ There are no more killings around the crossings than there are anywhere else in the park. ”

Walking over the Trans Canada and then walking underneath through one of the tunnels, I was amazed to see the fresh tracks of black bears, wolves, deer and many kinds of smaller animals. Somehow, all these animal footprints made me so happy, knowing that all this wildlife was passing safely under and over the longest road in Canada.

Hopefully, the success of the wildlife crossings in Banff will continue to inspire similar solutions around the world, where human pressure on wildlife continues to grow.

2 . Japanese researchers placed electronic devices(装置)on seals(海豹)in Antarctic waters to collect surprising information about the environment there. Japan’s National Institute of Polar Research started the research project in 2017. The team recently reported its results in a study in the publication Limnology and Oceanography.

Eight Weddell seals were fitted with the devices,which have antennas(天线)to send electronic signals.The 580-gram monitoring devices were attached(缚上;系上)to the animals’heads. They were designed to measure data such as water temperatures and sea salt levels.

Investigative teams on ships have difficulty reaching important research areas in Antarctica. These include areas along continental shelf formations where ice is attached to the shore, the National Institute of Polar Research said in a statement. Nobuo Kokubun led the project. Since the seals are active year-round, Kokubun added, “I thought we should have them collect the data.”

He told Reuters that the research also helps scientists follow the seals’ behaviors and learn about their relationship to the environment. “During the summer, we can go to Antarctica on icebreakers to conduct actual research activities, so that we can collect data there.” Kokubun said. ”But during the winter. such things cannot be done in so many places.“

Information gathered from the seals showed that one of the animals traveled as far as 633kilometers from Japan’s Showa Station in Antarctica. Another dove to a depth of 700 meters.Kokubun said the scientists learned from the data that warm seawater from the upper levels of the open sea reached Antarctica from March through the winter of 2017. The water flowed below the ice, bringing in sea creatures like Antarctic krill, an important food for seals.

Kokubun and his team plan to keep finding new ways to further examine the effects of climate change on Antarctic coastal areas. Next, he hopes to make the device small enough to fit on other animals at the South Pole, such as penguins,“The advantage with penguins is that they come back to the same place and we can collect data from them immediately,”Kokubun said.

3 . Chen Yuzhu, a 29-year-old young man, opened his first Chinese beef rice noodles restaurant in 2014 in the neighborhood of New York City’s Queens borough. He then took the flavor of his childhood memory to three other states in the US, building a recognized brand.

Actually, he started his own catering (餐饮) business after he lost his job and found noway out. It was at that time that beef rice noodles of his home village flashed in his mind.

However, the early days of setting up his business were not that easy. He frequently worked 18 hours a day, transported food at 2 am and promoted (推销) the restaurant near the New York City subway entrance by yelling, “Special noodles from my hometown, Guizhou!” But it didn’t work well. During the first two weeks. daily sales were only $200 at most, which wasn’t enough to pay the rent. He felt so anxious that he tried every possible means. Two months later, his Chinese beef rice noodles finally gained great popularity. His store has become hot spots for vloggers (视频博主) and he has made himself famous among locals as the“Rice Noodle Prince”.

“At first, running restaurants was for survival, but then I felt a sense of achievements. I became more open, inclusive and made a lot of friends. And the process to learn, make efforts and get inspired was really cool.” Chen said.

4 . When the pandemic(流行病) hit last spring, 9-year-old Zoe Benard of California started baking(烘) sweet treats with family members. But what started out as a fun way to pass the time has become a one-girl mission to raise $10,000 for Parkinson’s disease research.

Through a series of weekend bake sales since July, the homeschooled fourth-grader has taken in nearly $3,500 through the sale of her homemade banana bread, cookies and brownies. For a weekend sale, she’ll bake up to 25 pieces, four to five pans of brownies and three batches(炉)of cookies.

One hundred percent of the money made by selling treats is given to Team Fox, a research organization set up by actor Michael J.Fox, who has the disease. Zoe’s grandfather, 75-year-old Joe Contogenis, who is the inspiration for her sales, also has Parkinson’s. Contogenis can no longer run or play tennis the way he did before his diagnosis(诊断) three years ago.But he comes to every one of Zoe’s bake sales and is often moved to tears by the generosity of Zoe’s customers.

“She is a little entrepreneur(企业家) and has always been an out-of-the-box thinker,” Christine Eris, her mom, said. “we were cleaning our house out and found a magic set, and now she’s reading books on magic. She taught herself how to solve the Rubik’s Cube in a minute and a half. She just learns and practices things until she perfects them.”

Zoe sells her treats for $1 to $2, or $12 for a full piece of banana bread. Eris said many customers give more because they know it’s for a good cause. One customer arrived with a $200 check and another with a $100 bill. Zoe said her goal is to keep hosting sales until she reaches her $10,000 goal. Then she will either start over or find another cause to support. She also plans to start her own children’s cooking channel on YouTube because she finds the process of baking so fun.

7 . Many people, including some successful men, wear the same clothing daily to focus their decision-making energy on more important things.     1     Julia, an art teacher, is wearing the same dress for the first 100 days of school to create awareness of the environmental costs of fast fashion.

Available online or from various shops, it allows everyone to adopt the latest fashion trends instantly. Though that sounds like a win-win for all, the rapid change in styles and the affordable prices result in impulse (冲动) purchases, many of which are thrown away after being worn just once or twice.    2    

Julia's idea for the “One Outfit (服装), 100 Days” began as a comment she made to her husband during the summer.     3     Moreover, it would serve as a great lesson for her new students. Selecting a perfect outfit for the challenge was a little tricky.After some consideration, Julia settled on a plain dress. Though she has a backup dress, Julia plans to use it only if absolutely necessary.

    4     It has also inspired some of her colleagues and her husband to take up the challenge. Julia says the experiment has forced her to rethink her attitude towards clothes. She values things more now—respecting the planet for her children and trying to value herself in a different way, as opposed to caring so much about what she looks like.     5     Reuse, recycle, and, most importantly, reduce.

9 . This year’s Olympic Games have been closed to most spectators (观众) because of COVID-19, but the eyes of the world are still on the athletes thanks to five extra cameras—the first step in a 3D tracking system that supplies spectators with instant insights into each step of a race.

The tracking system being used in Tokyo, an Intel product called 3DAT, feeds live footage (影像) into the cloud. There, an artificial intelligence program uses deep learning to analyze an athlete’s movements and identifies key performance characteristics such as top speed and slowdown. The system shares that information with viewers by displaying the action of slow-motion, highlighting key moments. The whole process, from capturing the footage to broadcasting the analysis, takes less than 30 seconds.

“It’s like having your own personal commentator point things out to you in the race,” says Jonathan Lee, director of the Olympic technology group.

To train their Olympic AI via machine learning, Lee and his team had to capture as much footage of best athletes as they could. They needed recordings of human bodies performing specific moves, but the preexisting footage shows average people in motion, Lee says. “People aren’t usually seven feet in the air,” he notes, but world-class high jumpers reach such heights regularly.

In the footage, a team at Intel record every part of the body—eyes, nose, shoulders, and more. Once those key points were identified, the model began connecting them in three dimensions (维度) until it had a simplified performance of an athlete’s form. Lee thinks the AI could help everyone from Olympians to average gymgoers correct their form and track changes in their moves that may indicate upcoming injury. “Long-term, what this technology will do is help improve an athlete’s performance by giving them more information,” two-time Olympic champion Ashton Eaton said.
