Four people in England back in 1953, stared at Photo 51,It wasn't much—a picture showing a black X. But three of these people won the Nobel Prize for figuring out what the photo really showed –the shape of DNA The discovery brought fame and fortune to scientists James Watson, Francis Crick, and Maurice Wilkins. The fourth, the one who actually made the picture, was left out.

    Her name was Rosalind Franklin.” She should have been up there,” says historian（历史学家） Mary Bowden.” If her photos hadn't been there, the others couldn't have come up with the structure.” One reason Franklin was missing was that she had died of cancer four years before the Nobel decision. But now scholars（学者）doubt that Franklin was not only robbed of her life by disease but robbed of credit by her competitors

    At Cambridge University in the 1950s, Watson and Click tried to make models by cutting up shapes of DNA's parts and then putting them together. In the meantime, at King's College in London, Franklin and Wilkins shone X-rays at the molecule(分子). The rays produced patterns reflection the shape.

    But Wilkins and Franklin's relationship was a lot rockier than the celebrated teamwork of Watson and Crick, Wilkins thought Franklin was hired to be his assistant .But the college actually employed her to take over the DNA project.

    What she did was produce X-ray pictures that told Watson and Crick that one of their early models was inside out. And she was not shy about saying so. That angered Watson, who attacked her in return, “Mere inspection suggested that she would not easily bend. Clearly she had to to go or be put in her place.”

    As Franklin's competitors, Wilkins, Watson  and Crick had much to gain by cutting her out of the little group of researchers, says historian Pnina Abir-Am. In 1962 at the Nobel Prize awarding ceremony, Wilkins thanked 13 colleagues by name before he mentioned Franklin, Watson wrote his book laughing at her. Crick wrote in 1974 that  “Franklin was only two steps away  from the solution.”

    No, Franklin was the solution. “She contributed more than any other player to solving the structure of DNA . She must be considered a co-discoverer,” Abir-Am says. This was backed up by Aaron Klug, who worked with Franklin and later won a Nobel Prize himself. Once described as the “Dark Lady of DNA”, Franklin is finally coming into the light.

    "I didn't hear them call my name," explained Shelley Hennig to Active Teens (AT) as she talked about that exciting moment on national television when she won the honor of Miss Teen USA 2004. "Are you ready?" is what she heard. Then she said, "I shook my head no, and then they said 'yes' and it was announced again."

    It was four days after that life changing moment for the seventeen-year-old high school student from Destrehan, Louisiana — she was still on cloud nine.

    "I was so shocked! I never believed that it could actually really happen." Present in the audience that day were: her mother and father, older brother, her friends, and her dance teacher.

    Understanding why members of her family and her friends would be there, AT asked why her dance teacher had traveled so far to see her compete. "She's always been my role model. I've danced with her since I was six. She's been through so many difficulties and came through them all. I've learned to get over bad life's experiences and learned how to move on because of her."

    One of those bad life's experiences for Shelley happened three years ago when her brother Brad was killed in a drunk driving accident. He was 18. She found writing helped her get through the rough days. She said, "I write a lot about my brother. I write a lot, a lot, a lot..."

    As Miss Louisiana Teen, she traveled around the state speaking to teens about the dangers of drinking and driving. In her role as Miss Teen USA, Shelley will continue to speak to youth about safe driving, in addition to many other things to help the youth.

    When AT asked Miss Teen USA if she had any advice for our readers, she said, "Don't let anyone change you. Hang out with people that make you feel good about yourself. That way, it is easy to be yourself."

    When you get in your car, you reach for it. When you're at work, you take a break to have a moment alone with it. When you get into a lift, you play with it.

    Cigarettes? Cup of coffee? No, it's the third most addictive（使人上瘾的） thing in modern life, the cell phone. And experts say it is becoming more difficult for many people to curb their wishes to hug it more tightly than most of their personal relationships.

    With its shiny surface, its smooth and satisfying touch, the cell phone connects us to the world even as it disconnects us from people three feet away. It affects us in ways its inventors in the late 1940s never imagined.

    Dr. Chris Knippers, an expert at the Betty Ford Center in Southern California, reports that the overuse of cell phones has become a social problem not much different from other harmful addictions: a barrier to one-on-one personal contact, and an escape from reality.

    Sounds extreme, but we've all witnessed the evidence: the person at a restaurant who talks on the phone through an entire meal, ignoring his kids around the table; the woman who talks on the phone in the car, ignoring her husband; the teen who texts messages all the way home from school, avoiding contact with kids all around him. Is it just rude, or is it a kind of unhealthiness? And pardon me, but how is this improving the quality of life?

    Jim Williams, an industrial sociologist based in Massachusetts, he points to a study by Duke University researchers that found one-quarter of Americans say they have no one to discuss their most important personal business with. Despite the growing use of phones, e-mail and instant messaging, in other words, Williams says studies show that we don't have as many friends as our parents. “Just as more information has led to less wisdom, more acquaintances(熟人) through the Internet and cell phones have produced fewer friends,” he says.

    If the cell phone has truly had these effects, it's because it has become very widespread. In 1987, there were only 1 million cell phones in use. Today, almost 300 million Americans carry them. The number of cell phones is far more than that of wired phones in the United States.

    Scientists have been studying how people use money for long. Now they're finding some theories may apply to one group of monkeys.

    Researchers recently taught six monkeys how to use money. They gave the monkeys small metal disks(圆片) that could be used like cash and showed them some yummy apple pieces. The monkeys soon figured out that if they gave one of the disks to a scientist, they'd receive a piece of apple in return.

    If you think that is all the monkeys can figure out, you are wrong. Two researchers, Jake and Allison, acted as apple sellers in the experiments. The monkeys were tested one at a time and had 12 disks to spend in each experiment. Jake always showed the monkeys one apple piece, while Allison always showed two pieces. But that's not necessarily what they gave the monkeys. The number of apple pieces given for a disk was determined at random.

    Experiment One: Allison showed two pieces of apples but gave both pieces only half the time. The other half, she took one piece away and gave the monkey just the remaining piece. Jake, on the other hand, always gave exactly what he showed: one piece for each disk. The monkeys chose to trade more with Allison.

    Experiment Two: Allison continued to sometimes gave two pieces and sometimes one piece. But now, half the time, Jake gave the one apple piece he was showing, and half the time he added a bonus. Guess what? The monkeys chose to trade more with Jake.

    In the first experiment, the monkeys correctly figured out that if they traded with Allison, they'd end up with more treats. In the second one, when a monkey received two pieces from Jake, it seemed like again. When Allison gave the monkey only one piece instead of the two she showed, it seemed like a loss. The monkeys preferred trading with Jake because they'd rather take a chance of seeming to win than seeming to lose.

    We also sometimes make silly business decisions just to avoid the feeling that we're getting less, even when were not. Would you have made the same choices?

    Have you ever lost your car on a parking lot? It happens. You park and go shopping. When you get back, you have no idea where your car is. It can be discouraging.

    You don't need to install (安装) an expensive GPS system to keep track of your car. That's too expensive. You would need to pay a monthly subscription fee just to use it. But is there a way to track your vehicle without spending a fortune? Yes, now there is! A California-based start-up company was able to make this a reality. They created a tiny device (装置）that works with your smartphone, and it could be exactly what you're looking for! It's called TrackR Bravo. It's changing the way we keep track of the important things in our lives.

    Install the free TrackR app on your smartphone, connect the app to your device and you're ready to go! Simply attach TrackR to whatever you want to keep an eye on. The entire process of setting it up only takes 5 minutes or less. You can attach it to your keys, wallet and anything else you don't want to lose. Then use the TrackR app to find where your missing item are in seconds.

    Forget expensive GPS systems or tracking services. Nobody wants to pay expensive monthly subscription fees. We understand how stressful these things can be, and this is the reason why the company created TrackR. This device is your VIP when you need to take care of important things.

    If you forget where you park your car, take out your smartphone and open the TrackR app. Tap on the “lost item” sign on the screen and the app will tell you the exact location. This device is by no means expensive. TrackR only costs $29, a small price to pay for peace of mind. The device is small enough that you can attach it to your pets. Put it on their collar, and you will never lose track of them! Attach it to your key or wallet, and never waste a minute rummaging the whole house for it.

    Since you've been informed about this brilliant invention, now attach it to everything that's important to you.

    If you have never been on a cruise (乘船游览), it can seem like its own world—with its own rules and secret language. So here we are going to lay out the very basics of going on a cruise.

    Do I need a passport to go on a cruise?

    You may need a passport, but you should take one anyway. Besides the fact that you are going to need an ID card to board the ship in the first place, a lot of ports require one.

    How much luggage can I take on board?

    For the most part, cruise ships aren't like planes—there isn't a strictly regulated amount of luggage you can take with you, and you are not going to be charged for bringing too much. Keep in mind that cabin storage space can be tight. Everything, including your empty luggage, is going to have to fit inside and you don't want to be tripping over it for your whole vacation.

    Things like guns and knives are banned, but regulations vary from ship to ship about things like irons (generally a no) and hair dryers (generally a yes). Some ships allow you to bring a bottle of wine, but nearly all ban bringing your own hard alcohol.

    What's the process for boarding a cruise ship?

    Boarding a cruise ship is like boarding a plane—there are regulations or when to arrive, how to check-in, and what security you have to go through. Most cruise lines have transportation available from the airport; otherwise they normally own a paid parking lot where you can leave your car.
