The Oklalhoma teen's eyes were covered by two blindfolds（眼罩）. She didn't know she would meet her father, James, after 12-year separation.

    “I had actually discussed with her the night before at a restaurant and talked over the details of where we would go and how we would pull them of,” said Amanda, Rory Beth's mother.

    A video shows Amanda led her blindfolded daughter out of their car and guided her across the parking lot of Broken Arrow Lanes in Broken Arrow.

    Little did she know, her father was on the sidewalk holding a birthday cake that read, “Happy Birthday Rory Beth, Love Dad.” When the teen slowly pulled down her blindfolds, she was extremely surprised. Both the father and daughter stood silently looking at each other until James finally walked over and hugged her. James only broke their embrace to look at his daughter and hold her face. “There were definitely lots of tears from James, myself, and boys, and even a few bystanders,” said Amanda.

    James was a truck driver who spent a lot of time on the road, so Amanda ended the marriage with him when Rory Beth was a baby. “It was hard to figure out how to make it work,” Amanda said. Amanda felt Rory Beth was now old enough to understand and to ask any questions she may have, so the reunion happened.

    The birthday surprise was on June 4, and the father and daughter had seen each other again since, even celebrating Father's Day together. Amanda said her daughter and James were both delighted to be together.

    “She's already calling him 'daddy' and tells him that she loves him.” Amanda said.

    A person's chances of falling ill from a new strain (菌株) of flu are at least partly determined by the first strain they ever met with, a study suggests.

    Research in Science Journal looked at the 18 strains of influenza A ( 甲型流感) and the hemagglutinin protein (红血球凝集素蛋白) on its surface. They say there are only two types of this protein and people are protected from the one their body meets first, but at risk from the other one. A UK expert said that could explain different patterns in flu pandemics (流行病).The researchers, from University of Arizona in Tucson and the University of California, Los Angeles, suggest their findings could explain why some flu outbreaks cause more deaths and serious illnesses in younger people. The first time a person's immune system meets a flu virus, it makes antibodies targeting hemagglutinin protein that sticks out of the surface of the virus — like a lollipop (棒棒糖).

    Even though there are 18 types of influenza A, there are only two versions of hemagglutinin. The researchers, led by Dr Michael Worobey, classed them as "blue" and "orange" lollipops. They said people born before the late 1960s were exposed to "blue lollipop" flu viruses — H1 or H2 — as children. In later life they rarely fell ill from another "blue lollipop" flu — H5N1 bird flu, but they died from "orange" H7N9. Those born in the late 1960s and exposed to "orange lollipop" flu — H3 — have the opposite pattern.

    His team looked at cases of H5N1 and H7N9 — two kinds of bird flu which have affected hundreds of people, but have not developed into pandemics. The researchers found a 75% protection rate against severe disease and 80% protection rate against death if patients had been exposed to a virus with the same protein version when they were children.

    Dr Worobey said the finding could explain the unusual effect of the 1918 "Spanish flu" pandemic, which was more deadly among young adults. "Those young adults were killed by an H1 virus and from blood analysed many decades later there is a pretty strong indication that those individuals had been exposed to a mismatched H3 as children and were therefore not protected against H1. The fact that we are seeing exactly the  same pattern with current H5N1 and H7N9 cases suggests that the same fundamental processes may govern both the historic 1918 pandemic and today's contenders (斗争者) for the next big flu pandemic."

    Jonathan Ball, professor of University of Nottingham, said, "This is a really neat piece of work and provides a reason why human populations have been sensitive to different strains of bird influenza over the past 100 years or so. The findings are based on analysis of patient records and they certainly need further proof in the laboratory, but nonetheless the results are pretty amazing and inspiring."

Love for language

    Very few of us become fluent in another language by studying it in high school. I went to university and then moved across the country, pursued a demanding career, married and raised children.

    I made an effort to maintain the little bit of French that I learned in school, but eventually realized that this was pointless. I was well aware that new languages are best learned when young, and that our abilities in that regard decline with age. However, just before my 50th birthday, I signed up for French classes. After I was tested to see which group I belonged in, I was placed at almost the introductory level. When I looked around at my first Saturday morning class, I was struck by how many of the students were learning French as a third, fourth, or even fifth language.

    Contrary to my assumption that learning a new language was impossibly difficult, there were people who learned new languages as a matter of course. I found that it really was true that certain linguistic (语言的) abilities fade with age.

    While I'd always thought of myself as a quick learner, that was no longer the case. I absorbed new vocabulary very slowly. What I learned one week seemed to slip away as soon as I learned the next skill. I looked up the same words and language structures over and over again.

    Now, a couple of years in, I can listen to the news in French and catch 90 percent of it on the first try, read a novel if the language is not too difficult, and hold up my end of a conversation if it doesn't go too fast.

    Who knows what I might still accomplish?

    I've learned so much beyond grammar and vocabulary. I've met people from around the world and all walks of life who have the courage to make fools of themselves in order to learn something new.

    I've been taught by patient and inspirational teachers from many corners of the world, including France, Eastern Europe, the Caribbean and Africa.

    Listening to the news as it is presented to the people of France, I have a renewed understanding of how something can look completely different from another perspective. I've learned that a language is not just a set of words, but a way of thinking. But most of all, I've learned that it really is never too late to learn something new.

    Teenagers who spend hours in front of the television may have a poorer diet as young adults.

    A study, which included nearly 1, 400 high school students, found those who watched TV for five hours or more per day had less healthy diets than peers (同龄人) five years later. Why does this happen? Should the parents take any measures?

    On the one hand, people who spend a lot of time in front of the TV, especially teenagers, may snack more, and that may affect their long-term diet quality.

    On the other hand, TV ads for fast food, sweets and snacks tempt teenagers to eat more of those foods. And TV time might also replace exercise time for some kids.

    Lead researcher Dr. Daheia J. Barr-Anderson, of the University of Minnesota in Minneapolis, told Reuters Health a clear correlation between TV time during high school and diet quality in young adulthood. While the heaviest TV viewers were eating the most junk food, those who'd watched less than two hours per day had the highest intake (吸收) of fruits, vegetables, whole grains and high-calcium food. In her opinion, parents should limit and monitor TV viewing.

    As far as I am concerned, children should watch no more than two hours of television per day. And parents should set a good example by eating right, being physically active and curbing their own TV time.
