I'm part of the Roots & Shoots program founded by Dr. Jane Goodall. The program is intended to make and promote positive changes in the world. As Dr. Goodall says, "What you do makes a difference, and you have to decide what kind of difference you want to make."

    In Bulgaria, where I live, homeless dogs are everywhere. Many people here turn a blind eye to them. But I cannot ignore the life of a street dog whenever I see one wandering in the street, looking for something to eat. That's why I'm no longer a food waster. When I see wasted food, I always think of a hungry dog climbing to garbage bins, searching for food that people have thrown there. When eating in a restaurant, I'm not afraid to take leftover food to feed stray cats or dogs.

    A week ago, I saw a homeless dog around the garbage bins. Immediately I knelt down, spoke to her softly and ran my hands over her. I could see that she had had puppies. I couldn't imagine how she could have been able to care for them. Hours earlier, I'd bagged up a plate of leftover fish. As I unwrapped it, she wagged her tail and sniffed at it. She ate all the fish in no time.

    It's sad, isn't it? I can't understand why many of us waste so much and think little of it. These homeless animals have taught me that food is precious. Even when I don't have leftovers with me, I'll take the time to get something from the grocery store to feed them.

I know my power is small, so I hope that next time you see wasted food, do turn it into worthy food. You have the power to save a life!

    Humans have launched themselves into the outer space. They've landed on the moon. They've built habitable space stations that orbit the Earth. The next giant leap for mankind is to reach another planet – specifically, Mars.

    The problem is that it's no easy task. The planet is 586 times further away from the Earth than the moon, and it'll take around 180 to 220 days to reach Mars, depending on where each planet is in its orbit. Such long periods in space have suggested many potential health problems, including hormonal changes, skin conditions, and muscle and bone deterioration (损耗).

    Here's where some furry friends come in. A wide range of animals have been in space, from fruit flies and spiders to cats, and dogs. Such experiments began as far back as the late 1940s in first tests to see if living things could withstand the extreme g-force (重力) of a rocket launch.

    Mice continue to play a very important part in space experiments, mainly because the animals make excellent test subjects. They're small, which makes them inexpensive and easy to care for. In addition, their size and short life span make it possible to do the equivalent of several human years of tests in a much shorter time. Finally, because mice are mammals, they share many common characteristics with humans in terms of genetics, biology and behavior.

    Astromice have hit the headlines recently, as a team of scientists led by Betty Nusgens, professor of biology at the University of Liege in Belgium, found that the mice suffered a 15 percent thinning of their skin after 91 days aboard the International Space Station (ISS).

    This experiment was part of a wider NASA mission (任务) called the Mice Drawer System (MDS). The Italian Space Agency developed the facility, which allows six mice to be housed, monitored, and automatically fed and watered aboard the ISS, among which three survived during the mission.

    The mice have participated in 20 separate experiments, to study such effects as osteoporosis (骨质疏松症), anemia (贫血) and heart health.

    Results for the 20 experiments are coming in gradually. But it's clear that mice continue to play an important role in the ongoing quest to conquer the final frontier.

    The Pope John XXIII Regional High School robotics team has brought about many crea-tions in its laboratories. Most of these creations have earned them prizes in their robotics leagues, articles in local media and praise from many people around the world. None of them, however, can equal to what they experienced during one of their most recent projects.

    The robotics team helped design and build an electrically during one of their most recent projects, girl during an event snonsored by the GoBabyGo program and Toyota. The goal of the disabled is to build an electncally opiated vehicle and meet the needs of a specific disabled child. After hearing about the program, the robotics team jumped on the opportunity.

    When they got to the hospital for the event，the team members joined forces with engi-neers from University of Delaware, Toyota employees and and doctors to help a girl named Jaleah.

    Using instructions provided on an iPad by GoBabyGo,they put together a plastic battery-oper-ated vehicle-one of 12 that were made at the event-that was bespoke to Jaleah. Her vehicle was a baby blue jeep that had designs from the hit Disney movie Frozen and was decorated with snowflakes (雪花)，butterflies and flowers.

    More importantly，the team rerouted the electrical system in the car so that Jaleah only needed to push a large button on the steering wheel to drive the car, giving her the freedom to move. In addition, they helped design special seating structure to keep Jaleah safely secured.

    When they completed the project, Jaleah and her parents' reactions took the PJ robotics members by surprise.“ It was really satisfying,” PJ junior Austin Fett said. “When she was riding it, she was having so much fun. It was a great feeling. ”

    While they are looking forward to their future projects and competitions in the FIRST Technology Challenge league, the robotics team will always remember the days they helped Jaleah become a mobile kid.

    “We made something that she will love and use forever,” PJ senior Keith Johnson said.

    Shukri Noor, 12, arrived in Anchorage, Alaska, one year ago. The sixth grader and her family are refugees (难民) from Kenya. "Since I didn't speak English, it was hard to communicate with others," Shukri said. "I had no friends."

    "Anchorage receives about 130 refugees every year. Most are from Somalia. The rest come from Iraq, Sudan, Cuba, Central America, and other places. Like Shukri, many of the kids feel alone. They're dealing with a lot of adjustments (适应)," Katie Bisson says. She manages to support for newcomer students in the Anchorage School District (ASD).

    At the Newcomers' Center, the ASD offers a special program for students who are new to the US. The kids spend part of each day at the center and part of the day at their neighborhood school. At the center, the students study English and other subjects.

    The main goal is to help newcomers reach the point where they attend their neighborhood schools all day. "Until then," Bisson says, "they have the support of being with kids like them, who are facing the same challenges (挑战)."

    Anchorage has a population of 300, 000.Among the ASD's 48, 000 students, 98 languages are spoken. According to Bisson, the ASD's newcomers program helps students understand a new culture so they can "start off on the right foot".

    The Newcomers' Center gives attention to middle school and high school students. For younger kids, the ASD offers a six-week summer program, which Shukri attended. "It helped me learn the language," she says. "I played sports with kids after class, and I played math games with my classmates. I feel very comfortable now."

    Welcome to our school. You can do a lot of things here. Come and join us.
