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.

    Japan has long been known for both its strong traditions and being on the cutting edge of technology, and this new inn combining the classic Japanese surroundings with high-tech slippers and furniture is a perfect reflection of this.

    Nissan Motor Co. developed a system in which slippers park themselves at the entrance of the traditional inn, called “ProPilot Park Ryokan,” waiting for guests to use them upon arrival. When guests have finished using them, the slippers will drive themselves back to their original position. Each slipper features two tiny wheels, a motor, and sensors to drive it across the wooden floor.

    The same technology features in Nissan's all-battery electric Leaf car. High-tech sensors and cameras allow the vehicle to safely back into parking spaces without any input from the driver. Four cameras and 12 sensors assess the vehicle's surroundings. ProPilot Park handles the accelerator, braking and steering (转向) input when the car is parking. Drivers operate the system with the press of a button, which they must hold down the entire time. Lifting a finger off the button will result in the car stopping immediately.

    The inn, located in the resort town of Hakone, about 75 kilometers southwest of Tokyo, is currently most famous for its view of Mount Fuji. However, the new self-driving slippers, released by Nissan in March, is the unique feature of the high-tech inn.

    “The self-parking slippers are meant to raise awareness of automated driving technologies, and their potential, non-driving applications,” Nissan spokesman Nick Maxfield said in a statement.

    In addition to the slippers, office chairs, floor cushions and traditional low tables in the inn also wheel themselves back into place after use.

Holidays are the main times to see both sides of my family.

    At Thanksgiving, my mom, dad, brother and I go to my dad's side of the family, my grandpa's. When I was in 2nd grade, my grandma got in a car accident only miles from their house. At the time, I was in school. I was checked out and brought to church. Since then, holidays have never been the same. However, Thanksgiving is still good, although it would be better with grandma. At my grandpa's house, my uncle, aunt, dad and mom all get the dishes prepared for the feast. When the final family members arrive, and the food is downstairs, we dig in, the little ones first.

    Christmas is a little different. We have Christmas with my mom's side at my uncle's house, usually on Christmas Eve. We have dinner with homemade cupcakes for dessert, and relax until it is time to open presents. The kids get the most and we usually take a family photo. After everybody's gifts have been opened, my family say goodbye and go home.

    Easter has been a little different in the past few years. It started 3 years ago, when my family hosted my mom's side of the family. We put our dishes we made for the day on the counter. We kids go downstairs and play ping-pong or football. We are called up when everything is ready and begin eating. The kids go to a table in the living room, and the adults use the kitchen table. That is usually the Easter day for us.

    Each tradition gets better and better each year for some reason. I wonder what new traditions my family might come up with in the coming years.

    Cold weather during winter months may keep many people from leaving home and running in the open air.

    However, a new study shows that the drop in temperature is a good reason to run. In fact, researchers say, running in cold weather helps improve one's performance.

    Many people say running in the winter can be difficult. Two reasons are the low temperatures and bitter winds. Yet many runners might find it easier than running in hot weather.

    That could be because lower temperatures reduce stress on the body. When you run in cold weather, your heart rate and the body's dehydration (脱水) levels are lower than in warmer conditions. The body needs less water on a cold day than in warm weather.

    This information comes from sports scientists at St. Mary's University in London. John Brewer is a professor of applied sport science at St. Mary's.

    For this study, he and other researchers put a group of people into a room they called an “environmental chamber.” The researchers then recreated summer and winter weather conditions in the room. The test subjects were asked to run 10,000 meters under both conditions. Brewer says he and his team recorded biological measurements of the runners.

    “We've got a group of subjects into the environmental chamber, we've changed the conditions to replicate the summer or winter and we've got them to run a 10km under both of those conditions and taken various measurements on each runner while they've been completing their 10km.”

    Brewer says every movement runners make produces heat. He explains that one way in which we lose heat is by sweating. The body loses heat through droplets of sweat. He says the body also loses heat by transporting the blood to the surface of the skin.

    Kentucky Fried Chicken has filed a lawsuit（提起诉讼） against three companies in China, because their social media accounts spread false information about its food, including that its chickens have eight legs. The case comes as the Beijing government holds an activity to clean up rumours （谣言）on social media（媒体）. Internet marketers have been accused （指控） of trying to control online opinions of their customers by posting false information about their competitors.

    In an announcement posted on its Chinese website, KFC said one of the best-known false rumours was that chickens used by the company have six wings and eight legs. It is requesting 1.5 million yuan and an official apology from each of three companies. It is also asking for an immediate stop to their activities to hurt it by spreading rumours.

    The fried chicken chain is China's biggest restaurant operator and is a kind of fast food for young people in China. It has more than 4, 600 restaurants in the country, and on average, opens a new branch every day. KFC'S China chief executive officer（行政长官）, Qu Cuirong, said that it is difficult for companies to protect their brands（品牌） against rumours because it is hard for them to collect evidence. She added, "The efforts by the government in recent years to purify（净化） the online environment have offered us much more confidence."

    The companies are Shanxi Weilukuang Technology Company, Taiyuan Zero Point Technology Company and Yingchenanzhi Success and Culture Communication in Shenzhen, south-east China. Calls to numbers listed for the companies either rang unanswered or were not available. In fact, authorities（官方） began an activity two years ago to clean up what they called online rumours. Comments in state media have argued that a clean-up is needed.

    The final results of Best-Ever Teen Fiction vote are in. While it's no surprise to see Harry Potter and The Hunger Games series on top, this year's list also highlights some writers we weren't as familiar with. For example, John Green, author of The Fault in Our Stars, appears five times in the top 100.
