The Amazing Penguin Rescue

    The summer of 2016, the ship MV Treasure sunk, creating an oil spill. Thirteen hundred tons of fuel oil were flowing right in the middle of the African Penguins' habitat. Soon the oil covered about 20,000 penguins. Without swift help, the seabirds would have no chance for survival. Volunteers were showing up by the thousands and I also took part in what was the largest animal rescue operation ever.

    A warehouse was turned into a rescue center near the habitat and hundreds of pools were built to hold about 100 oiled birds each. When walking into the center, I couldn't believe my ears. I had expected to walk into a chorus of honking and squawking(叫声). Instead, the center sounded like a library. The penguins were dead silent. My heart ached for the painful birds. Cleaning them all seemed like an impossible task. But we had to carry on like doctors in an emergency room. There was no time for doubt. Cleaning oil off a penguin wasn't easy. Even with more than 12,500 volunteers, it took a month to bathe all 20,000 birds at the center.

    While volunteers were busy bathing the oiled penguins, another crisis (危机) was developing. Oil from the spill had started moving north. Tens of thousands of penguins were in the oil's path. But we already had our hands full with 20,000 recovering birds. If any more birds were oiled, we wouldn't have enough resources to save them.

    One researcher came up with an idea: What if the penguins were temporarily moved out of harm's way? Experts decided to have a try. Volunteers rounded up the penguins and released them 500 miles away. The hope was that by the time the seabirds swam home, the oil would be gone. The plan worked! Another 20,000 penguins were saved.

    The entire penguin rescue took about three months. More than 90% of the oiled penguins were successfully returned to the wild. Looking back on the rescue, I am still amazed by the work of the volunteers. What I could hardly believe was that we accomplished an impossible task.

    There is a breakthrough in building aircrafts. Bendable wings covered with overlapping(部分重叠) pieces resembling fish sizes could be used to build swifter, fuel-efficient aircraft, a new study finds.

    Nowadays, conventional aircrafts typically rely on ailerons (副翼) to help control the way the planes tip as they fly. However, when the Wright brothers flew the first airplane, Flyer 1, over a century ago, they used no ailerons but wires and pulleys that twisted the wood-and-canvas wings, to control the plane.

    Scientists have long sought to develop aircrafts that can alter their wings during flight, just as birds can. However, most previous attempts have failed because they relied on heavy mechanical control structures within the wings. These structures were also complex and unreliable, said Neil Gershenfeld, a physicist and director of the Center for Bits and Atoms at Massachusetts Institute of Technology (MIT).

    The new wing consists of a system of tiny, strong, lightweight modules. The shape of the wing can be changed uniformly along its length using two small motors, which apply a twisting pressure to each wingtip. These wings are covered in “skins” of overlapping strips of flexible material resembling fish sizes. These strips move across each other as the wings alter, providing a smooth outer surface, the researchers explained.

    Wind-tunnel tests of these wings showed that they at least matched the aerodynamic properties of conventional wings, at about one-tenth the weight. Initial tests using remotely piloted aircrafts made with these wings have shown great promise, said Benjamin Jenett, a graduate student at the Center for Bits and Atoms at MIT.

    The new modular structures the scientists developed could be manufactured quickly in mass quantities and then installed by teams of small robots. These modular structures also can be disassembled more easily, making repairs simpler.

    “Still, the first aircraft built using this strategy will not be a passenger jet, ”Gershenfeld said. “Instead, the technology will likely first be tested on unmanned aircraft, leading to drones (无人机) that can fly for a long time, to help deliver internet access or medicine to remote villages and do some rescue works.”

    Sixteen years ago, I learned an important life lesson in the back of a New York City taxi.

    I was on my way to Grand Central Station, and we were driving in the right lane when a black car suddenly sped out of a parking space right in front of us.

    My driver fit the brakes hard, skidded, and missed the other car by a few inches. The driver of the other car, the man who had just nearly caused a huge accident, started shouting at us. My taxi driver just smiled and waved at him. He was really friendly!

    “Why did you just do that?” I asked him. “This guy almost destroyed your car and could have sent us to the hospital!”

    This was when my taxi driver told me what I now call “the Law of Garbage Trucks”.

    “Many people are like garbage trucks. They run around full of garbage, full of anger, and full of disappointment,” he said. “As their garbage piles up, they need a place to dump it, and if you let them do, they'll dump it on you. So when someone wants to dump on you, just smile, wave, wish them will, and move on. You'll be happier because of what you have done.”

    I started thinking, how often do I let Garbage Trucks run right over me? And how often do I take their garbage and dump it on other people—at work, at home, or on the street? It was on that day that I said, “I'm not going to dump anymore.”

    In the classic marriage vow (誓约), couples promise to stay together in sickness and in health. But a new study finds that the risk of divorce among older couples rises when the wife－not the husband－becomes seriously ill.

    "Married women diagnosed with a serious health condition may find themselves struggling with the impact of their disease while also experiencing the stress of divorce." said researched Amelia Karraker.

    Karraker and co-author Kenzie Latham analyzed 20 years of data on 2,717 marriages from a study conducted by Indiana University since 1992. At the time of the first interview, at least one of the partners was over the age of 50.

    The researchers examined how the onset (发生) of four serious physical illnesses affected marriages. They found that, overall, 31% of marriages ended in divorce over the period studied. The incidence of new chronic (慢性的) illness onset increased over time as well, with more husbands than wives developing serious health problems.

    "We found that women are doubly weak when their marriage breaks up in the face of illness," Karraker said. "They're more likely to be widowed, and if they're the ones who become ill, they're more likely to get divorced."

    While the study didn't assess why divorce is more likely when wives but not husbands become seriously ill, Karraker offers a few possible reasons. "Gender roles and social expectations about caregiving may make it more difficult for men to provide care to sick spouses." Karraker said. "And because of the imbalance in marriage markets, especially in older ages, divorced men have more choices among potential partners than divorced women."

    Given the increasing concern about health care costs for the aging population, Karraker believes policymakers should be aware of the relationship between disease and risk of divorce.

    "Offering support services to spouses caring for their other halves may reduce martial stress and prevent divorce at older ages." she said. "But it's also important to recognize that the pressure to divorce may be health-related and that sick ex-wives may need additional care and services to prevent worsening health and increased health costs."

    Many people like travelling, but they cannot take their dogs wherever they go. Some people let their dogs stay alone at home while others ask someone else to take care of their pets. If you're leaving your beloved pet at home for a holiday, it can turn into a bad experience. Luckily, you don't have to worry about your dogs any more because Rover can cover for you while you are on leave. Rover is the latest service to offer at­home dog boarding. It's a good alternative (替代物) to boarding your dog at a dog boarding kennel (狗舍) or your neighbour's house.

    The way Rover works is sort of like Airbnb. Dog owners browse the "search" section of the site or app for pet sitters, which can be organized by zip code and available dates. Information of pet sitters is provided, complete with many reviews, specific services and rates. Now Rover has over 25,000 pet sitters in more than 5,000 US cities. And they're all experienced pet sitters.

    After finding someone that meets your needs, just send messages to the pet sitter to arrange a meeting. Then, like Rover says, all that is left to do is relax! Rover's pet sitters are encouraged to send text and picture information throughout the day, and if there's a medical emergency, the site will send a vet. Besides, don't worry about a pet sitter who falls through, because someone else will soon take his or her place.

When I was about twelve, I headed to a restaurant for dinner with my family. It was winter, and on that night the wind was really blowing hard. 

As my mum and I headed to the restaurant from our car, a girl about my age and her mother came up to us. They asked if we had any spare change(零钱). My mum right away asked where they lived. They pointed to an old car in a parking lot across the street. The girl said there were six of them living in that car. 

My mum said she had something to do after handing the people a few dollars. She sent me inside the restaurant with my dad and my three siblings(兄弟姐妹). But she didn't come. Later, I found out she had gone home and put all the food in our cupboards into a few bags. Then, she brought that food over to the car and handed the bags to the family. I wasn't there when that happened, but I can only imagine the joy it brought to those people. A few days later, when I actually found out about what she had done, I asked her why she helped those people. She told me that they were not lucky. I remembered the face of that girl who had asked us for change. She was the same age as me, yet we looked so different. 

Here I stood, dressed in almost new clothes, headed to eat in a restaurant and then went back home to the bedroom I shared with my younger sister. I remembered thinking the other girl didn't have any food to eat and that she was heading back to a cold car shared with five other people. 

After painting this picture in my mind, I understood why my mum had done what she did. I will never forget what she did that night, and how she taught me one of the best lessons I have ever learned.
