    Bees and other pollinators(传粉者)  use smells to track down fresh flowers. Air pollutants can weaken those scents(气味).  Scientists had worried this might make it harder for some pollinators to find a meal.

    Many animals help pollinate plants. Species that do this include bees, butterflies, etc. But for many reasons, the pollinators available to help plants in this way are decreasing. Scientists think a loss of habitat(栖息地)can be one factor. Diseases and exposure to poisonous chemicals also count.

    Jose Fuentes points to air pollution as another possible factor. He's an atmospheric scientist at Pennsylvania State University. In an earlier study, he showed some air pollutants could weaken or destroy scents emitted(发出)by flowers.

    Searching for a meal leaves pollinators out in the open and at risk of becoming other animal's lunch. And any time spent hunting food is time away from their duties back home, like protecting a hive(蜂巢)or nest, explains T'ai Roulston. He's an insect biologist at Virginia University. Roulston worked with Fuentes on the new study.

    In the study, the researchers focused on five kinds of representative scent molecules(分子)plants emit. One molecule they looked at, for example, is called beta-myrcene. Many flowers give off this chemical into the air.  Normally, this gas can travel some 800 meters from its flower source. But in polluted air, this same molecule could travel only half as far.

    Worse still, air pollution might do more than just weaken scent plumes(气味烟云).Chemical reactions between air pollutants and plumes may transform the flowers' smells, creating new scents. And these scents may be unrecognizable to pollinators.

    That's certainly Fuentes' concern.  So, he says his next research project will look at how insects handle any new flower scent. "It's possible that some insects will change ways to detect and use these new molecules to find food," he says.

    Whenever we talk about holidays, my mother teases my sister and me about how we “make out like robbers.” She is referring to the fact that we are half Jewish and half Indian, so we receive gits on both the festivals of lights. Hanukkah and Diwali. Though my mother teases us, I do not mind getting two sets of gifts!

    Hanukkah is celebrated on the 25th day of the Jewish month. Which is usually sometime in December. On Hanukkah, like most Jewish families. We light a menorah and say a prayer each night. We also say a special prayer on the first night. After that, it is a tradition tor my sister and me to do 'hot and cold', for our hidden Hanukkah gifts. When we walk towards the gift, our parents say 'hot' and when we walk further away, they say 'cold'. We each receive one present every night of Hanukkah. Another part I like about this holiday is seeing family members who we do not see often. My aunt usually stays for a few days, and we sometimes visit other relatives.

    Diwali is celebrated on the 13th day of the dark fortnight of the month of Ashwin(October / November). To celebrate Diwali, my family does a pooja, or prayers, in honor of the goddess Lakshmi. Since she is the goddess of wealth and prosperity, the pooja includes washing silver coins in milk and water. In India, people decorate their houses with lamps, similar to the way you might light up your house for Christmas. My family just places a few candles outside We also set off firecrackers, which is my favorite part. We often do this activity with friends to add to the excitement.

    Both holidays have different histories and stories. We celebrate them in different ways, yet they both have the same meaning. They both translate into. Festival of Lights, and they both mean family and presents for me!

    Every day when Glen Oliver orders his morning coffee at the drive-through window of a local cafe, he insists on paying for the order of the person behind him. He also asks the restaurant workers to tell the customer to have a great day, in case they're not already having one.

    Oliver has never made a big deal out of his own generous actions until a letter was published by a news website in November. He found out that he had not just bought someone his breakfast —he had saved a life.

    According to the website, someone had written a letter stating that on July 18th, he was planning on committing suicide. The writer said that while he was at the drive-through window, he was planning on going home, writing a note and ending his life. When he went to pay for his coffee and muffin, however, the cashier told him that the man in the SUV in front of him had picked up the tab and told him to have a great day.

    “I wondered why someone would buy coffee for a stranger for no reason,” said the writer. “Why me? Why today? If I were a religious man, I would take this as a sign. This random act of kindness was directed at me on this day for a purpose.”

    When the writer arrived home, he couldn't hold back his tears and started to think about the simple good deed that had affected him so deeply. “I decided at that moment to change my plans for the day and do something nice for someone. I ended up helping a neighbor take groceries out of her car and into the house.”

    The writer says that in the months following that fateful event, he does at least one kind thing for others every day. “To the nice man in the SUV, thank you from the bottom of my heart. Please know your kind gesture has truly saved a life,” he said. “On July 18, 2017, I had the greatest day.”

    Spring is coming, and it is time for those about to graduate to look for jobs. Competition is tough, so job seekers must carefully consider their personal choices. Whatever we are wearing, our family and friends may accept us, but the workplace may not.

    A high school newspaper editor said it is unfair for companies to discourage visible tattoos (纹身), nose rings, or certain dress styles. It is true you can't judge a book by its cover, yet people do "cover" themselves in order to convey certain messages. What we wear, including tattoos and nose rings, is an expression of who we are. Just as people convey messages about themselves with their appearances, so do companies. Dress standards exist in the business world for a number of reasons, but the main concern is often about what customers accept.

    Others may say how to dress is a matter of personal freedom, but for businesses it is more about whether to make or lose money. Most employers do care about the personal appearances of their employees, because those people represent the companies to their customers.

    As a hiring manager I am paid to choose the people who would make the best impression on our customers. There are plenty of well-qualified candidates, so it is not wrong to reject someone who might disappoint my customers. Even though I am open-minded, I can't expect all our customers are.

    There is nobody to blame but yourself if your set of choices does not match that of your preferred employer. No company should have to change to satisfy a candidate simply because he or she is unwilling to respect its standards, as long as its standards are legal.
