1 . In 2000, when I was around seven years old, my parents, sister, brother, and I were coming back from a T-ball game. There, in our driveway, we spotted two adult geese and a small gosling. The adults were startled by our return and flew away, but their baby was still too young to fly. We are no strangers to wildlife, so we avoided physical contact with the small gosling out of fear that it would keep us in its mind and be lost to its family forever. Hours passed, and night fell. The tiny little thing was wandering around our yard, unaware of what could happen.

And then another morning. And still another. Each morning, we would try to drive the goose over to his parents, who kept coming back to our yard. He wouldn’t go to them, though, and they wouldn’t come close enough to collect him. My sister Joanna decided to call the little guy Peeper, because he would follow us around the yard making a peeping noise, nonstop.

Almost a year passed. My family filled our days with feathery hugs and my dad would throw Peeper up into the air so he could fly a circle around the house.

One evening, my uncle came, and my dad wanted to show him Peeper’s circle. He threw him up in the air, but this time, Peeper just flew off. Everyone was very, very sad. We looked for him for days, calling his name, but he didn’t come back. Twenty years passed, and Peeper became a fond memory for my family.

Geese are very loyal, never forgetting their first home. Even so, it came as a total shock to me when, in 2020,an aging adult goose appeared at my home. At first, I assumed it was just another goose. After two weeks of the goose coming back repeatedly, it became clear to me that this wasn’t a random goose. He did all of the same things Peeper used to and responded to the name Peeper. My old best friend returned, 20 years later.

People desire connection with the natural world. Through Peeper, I have learned so much about myself and about the nature of love.

3 . A Teacher’s Lifesaving Call

In the midst of the COVID-19 pandemic, Julia Koch began what was only her second year as a first grade teacher in a virtual classroom.

One September afternoon a few weeks into the school year, she received a call from Cynthia Phillips, who was having technical difficulties with her granddaughter’s tools for online learning.

Koch immediately knew something was wrong with Phillips. The two women had spoken numerous times before, but Koch had never heard the grandmother sound quite like this. Her words were so jumbled that Koch could barely understand her, though she was able to make out that Phillips had fallen four times that day.

Koch called her principal, Charlie Lovelady, who assured her that he would call and check on Phillips himself.

Just like Koch, Lovelady could barely understand Phillips. He suspected she might be having a stroke—he recognized the signs from when his own father had suffered one. Lovelady was able to make out the word “kids” and immediately became concerned that Phillips’s two grandchildren, aged six and eight, were probably home alone with her—she   is   their primary guardian—and scared. Lovelady asked his office manager to send an ambulance to the grandmother’s home. Then Lovelady called two deans in the school district, to tell them what was going on, both of whom dropped everything and drove to the family’s home.

When they pulled up less than ten minutes later, the EMTs(急救人员)were treating Phillips while the two girls, looking visibly shaken, were outside with a neighbor.

The quick response from Koch and Lovelady saved Phillips’s life. She arrived at the hospital in time to get treatment and before chronic damage occurred.

“If it weren’t for them, I wouldn’t be here,” said Phillips from her hospital bed about a month after her stroke.

Thanks to an extended stay in the hospital, she has regained most of the movement throughout her body except for one hand and a portion of her mouth, which affects her speech.

5 . Marcus Eriksen was studying Plastic pollution when he met camel expert Ulrich Wernery. They went deep into the desert and spotted a camel skeleton (骨架). Eriksen was not prepared for what he saw in the desert. "I was just appalled," he said, "because inside the dead body of a camel was a mass of plastic bags, which was as big as a medium-sized suitcase."

Wernery is a scientist working in a research lab in Dubai. Since 2008 Wernery's team has examined 30,000 dead camels. They found 300 of those dead camels had a mass of plastic bags in their bodies. As camels wander in the desert, they eat plastic bags and other rubbish that move into trees and pile up along roadsides. "To a camel, if it's not sand, it's food," explains Eriksen.

Tightly packed masses of indigestible (难消化的) things can be built up in the digestive system of people or animals. Scientists call them bezoars (胃石). Normally, these are made of vegetable fibers or hair. Werner and Eriksen call those found in the camels "polybezoars". It points to their origin: plastic polymers.

In a new study, Eriksen and Wernery report data suggesting that each year these polybezoars are killing off around 1 in every 100 camels. Of five camel bezoars analyzed for this study, the plastic content ranged from 3 to 64 kilograms. "If it is confirmed that 1 percent of camels died due to plastic by future and more detailed studies, then plastic pollution will certainly be important concern for camels," says Luca Nizzetto, an environmental scientist. "Such studies are important, because they raise social awareness about this pollution."

Banning plastic bags and single-use plastics is crucial for protecting camels and other wildlife, Eriksen says. "Plastic bags blow out of garbage cans, out of landfills, out of trucks and out of people's hands." What's more, he adds, "They travel for hundreds of miles."

6 . Flu season generally dies down in March and April, but will the coronavirus( 冠状病毒) go with it? Whether the coronavirus that's quickly spreading around the world will follow the flu season and fade away with spring's arrival is unsatisfyingly uncertain. And many scientists say it's too soon to know how the dangerous virus will behave in warmer weather.

Dozens of viruses exist in the coronavirus family, but only seven afflict (折磨) humans. Four are known to cause mild colds in people, which are common, while others are more novel, deadly, and thought to be transmitted from animals like bats and camels. Health officials have labeled this new virus SARS-CoV-2 and its disease COVID-19. The prospect that summer could delay a pandemic is tempting. Earlier this year, Donald Trump tweeted about China’s efforts to contain the virus, saying they would be successful, “especially as the weather starts to warm.”

Viruses that cause influenza or milder coronavirus colds do tend to subside in warmer months because these types of viruses have what scientists refer to as “seasonality,” so the president's comments have some scientific backing. But it's highly uncertain that SARS-CoV-2 will behave the same way. Those currently studying the disease say their research is too early to predict how the virus will respond to changing weather.

“I hope it will show seasonality, but it's hard to know,” says Stuart Weston, a researcher at the University of Maryland, where the virus is being actively studied. As of Tuesday morning, more than 800,000 coronavirus cases had been confirmed in 74 different countries, with experts saying the disease is likely to keep spreading.

And relatively recent research suggests that dry, cold air may also help viruses stay unbroken in the air or travel farther as they become airborne.

Scientists assume that low humidity, which often occurs in winter, might weaken the function of the mucus(粘液)in your nose, which your body uses to trap and drive foreign bodies like viruses or bacteria away. Cold, dry air can make that normally thick mucus drier and less efficient at trapping a virus.

7 . Technology is a double-edged sword(双刃剑)— while it brings convenience, it also brings new problems. The sword of “social media” even has its preference: It cuts deeper into girls than boys.

Jean Twenge, a professor at San Diego State University in the US, recently discovered an alarming trend: Since 2010, the number of teenage girls who suffer from major depression, showing signs like self-harm and suicide (自杀), has increased much faster than that of boys. It is social media again that is to blame.

Statistically, girls use social media more than boys. Boys tend to spend their screen time on games, where they talk to their teammates through headphones. Though not directly, this still counts as real human contact. Girls, however, simply type and browse through posts, which is a much more isolated (孤立的) experience. “They're not having a real-time conversation with someone most of the time,” Mary Fristad, psychologist at The Ohio State University, told NPR.

And when it comes to online shaming, girls are also more vulnerable than boys. “Girls face more pressure about their appearance, which could be exacerbated (加重) by social media,” wrote Twenge. Shannon McLaughlin, for example, is an 18-year-old from Blackburn College in the US. She shared with the Guardian how social media made her feel depressed.

But McLaughlin found a solution. She started volunteering with the National Citizen Service, where she made face-to-face contact with people. "It's so easy to forget the importance of real connections when we have hundreds of people that we' re trying to impress at our fingertips," she told the Guardian. And she hopes that others "look up from their phones and focus more on the world around them".

9 . One summer during high school, my mom volunteered me to help Grandpa research our family tree. Great, I thought, imagining hours spent pawing through dusty, rotting boxes and listening to boring stories about people I didn't know. "You'll be surprised," my mom promised, "Family histories can be very interesting."

In truth, Grandpa didn't want to limit my work to just research, hoping to also preserve our family memories. He'd discovered a computer program that helps digitally scan old pictures and letters to preserve their contents before they crumble from old age. Grandpa wanted me to help him connect the scanner and set up the computer program. He could type documents and send emails, but had never used a scanner.

Soon after, I became fascinated with my relatives' lives. I asked Grandpa to tell the story behind every picture and letter we scanned. The stories, which turned out not to be boring at all, helped me not only understand but also relate to my relatives. I became so hungry for more information that Grandpa needed additional props to keep me satisfied. He showed me a chest filled with random stuff, all covered in dust.

Perusing through their belongings, I felt I was opening a window into the world of my relatives, a world long since gone. Grandpa showed me a bundle of letters he had sent to Grandma from the front lines of World War II and I could almost smell the gunpowder. I turned the pages of my great-grandmother's recipe book and could picture her cooking in her kitchen. All of the people who had been merely names to me now had faces to match.

Later, Grandpa admitted, "I probably could have done this project myself. I just wanted someone to share it with." I can't thank him enough for sharing the experience and making me appreciate the family members who have made me the person I am. I will cherish family memories and hope that someday will be able to pass them down to my own grandchildren.
