Tyler Kellogg drove more than 3,000 miles last year. His goal is to help as many people as he can.

    Tyler Kellogg calls himself a long-time do-gooder, and last summer he really did a lot of good. After collecting together $2,000 and using his car as a sleeping space, the 21-year-old college student hit the road. His goal was to do random acts of kindness for 100 strangers.

    He drove 1,600 miles, from his parents' house in Adams Center, New York, to the Florida Keys, then back again. “The first person I helped was a person fixing a boat lift on a lake in Oneida, New York,” Kellogg remembers. “I was shaking when I asked if he needed a hand.” What if he thought Kellogg was crazy? “When he said, ‘can you help me get this lift into the water?' I knew everything was going to be fine.”

    He helped a policeman fix a downed barricade(路障) in Washington, D.C., and spread many yards of mulch(护盖物) in Maryland and North Carolina. And somewhere outside Atlanta, he met a man who was crying because his wife had recently died and he had no one to talk to. “For three hours we sat in his garden,” Kellogg says. “When I left, he said, ‘Thank you. I realize now that my life will go on.' ”

    In 55 days, Kellogg helped 115 strangers and made an exciting discovery. “You don't have to have much money,” he says. “You just have to ask people, ‘How can I help?' ”

    With freezing temperatures on the way, now it is the time to take steps to protect your four-legged family members from the cold, wet weather San Antonio winters often bring. With a few simple measures, you can ensure your pets stay happy and healthy throughout winter.

    What is the best way to protect your pets during freezing cold weather? Bring them inside. Pets (especially cats) are safer indoors. Can't have your pets inside the house? Purchase a dog house or give your pet a safe, warm place to rest.

    Certain pets are more vulnerable (易受伤害的) to cold temperatures than others. Short-haired dogs, very young or old dogs and all cats should not be left outside during winter months. Short-haired dogs may benefit from a sweater while outside.

    Pets that spend much of their day outdoors will need some extra food throughout the winter months. That's because they use up more energy trying to stay warm. A few extra kibbles probably won't hurt but make sure your pets are getting daily exercise if they're easy to gain weight. Always provide fresh, clean water regardless of the season. Check water daily and clean bowls regularly.

    Be mindful of your pets while winterizing your car. Antifreeze (防冻剂) is deadly to pets that are attracted to its sweet taste. Store all chemicals out of reach, especially if are going to bring your pets into the garage on cold nights. It is necessary to warm up the car before you head out with your pet. A warm engine can be a welcome spot for a cold cat and the noise should scare them away before your start the engine.

    San Antonio's Animal Care Services wants to remind people that the City of San Antonio has laws that protect pets from neglect, including exposure to freezing weather conditions. Animal Care Service warns that if you find any pet around being left in the freezing cold weather, you can call the City's 311 Customer Service line.

    International Robotics Forum（论坛）

    Tokyo Big Sight, Tokyo, Japan, December 4-5

    The Robotics Society of Japan ( RSJ) , to provide opportunities for young robot lovers to learn more about industrial and service robots, is going to hold the International Robotics Forum that will cooperate with this year's International Robot Exhibition.

    The lectures and explanations throughout the Conference will be given in Japanese but will be interpreted into English at the same time. The Conference will offer a great opportunity for senior high school students from all around the world to communicate with each other through robots. Therefore, we look forward to your active participation.

    The event will take place two days. On the morning of Day One, Prof. Shin' ichi Yuta of the Shibaura Institute of Technology will give a lecture on basic mobile robotics and learning through robots.  This will be followed by a talk by Mr.  Kazuhiko Yokoyama of Yasukawa Electric Corporation who will explain the mechanism and control of robots and also point out the highlights(最精彩的部分）of the International Robot Exhibition.

    We will prepare a challenge for all the participants.  We will send you themes for robot research. You will study them in advance, and on the afternoon of Day One, you wi11 visit the Tokyo International Exhibition Center and investigate (详细研究）real robot . You will be able to experience fun and excitement of advanced robot technologies.  On the morning of Day Two, you will present your study and investigation results.

    On the afternoon of Day Two，as the final event, awards will be given by the RSJ to groups that have given outstanding presentations.

We hope that many future robot researchers and engineers will be born today.

    A dog spent the last four years of his life waiting a crossroad in the Thai city of Khon Kaen as if waiting for someone. People originally thought the dog had been abandoned, but then realized that he looked healthy, so people asked around about him. It turned out that the dog had indeed been spending most of his time around that crossroad, but a woman had been coming round regularly to bring him food and water.

    One day, while photographing the dog everyone called Leo, a reporter met the woman who had been taking care of him. She had come to drop off some food. After learning the story about the dog and the woman, the reporter decided to share the story on social media. The post soon went viral and the photos of Leo got shared hundreds of times. And the photos reached the eyes of Leo's former old owner.

    Nang Noi Sittisarn, a 64-year-old woman from Thailand's Roi Et Province, almost had a heart attack when her daughter showed her a photo of the beloved dog named BonBon she had lost during a car trip. When she learned that he had been waiting for her in the same spot for the last four years，her heart melted(融化).

    Auntie Noi told her daughter to drive her to where the dog was waiting. When she got there and called his name. BonBon, the poor dog started wiggling(扭动)his tail and came to her, but when she tried to take him home with her, he was unwilling to follow. She didn't want to force the dog to come with her, so she agreed to leave him with his new master. However, she and her daughter will come to visit him regularly.

We are what we eat. That is an old expression, but one worth knowing. A recent look at diets around the world shows that people who eat healthy food—and not too much of it—live longer. But which areas of the world have the best diets？Researchers found that foods in some of the healthiest diets—Mediterranean, New Nordic, Japanese and French—may be very different, but they are all heavy on local, seasonal and limit processed foods, which are high in vegetables and seafood and low in red meat.

Mediterranean diet contains lots of fruits, vegetables, whole grains, nuts and olive oil. The diet has proper amounts of fish and poultry (禽肉). Red meat and foods high in sugar and salt are not big parts of this diet.

New Nordic diet has whole grains like oats and rye, vegetables such as carrots, broccoli and eggs, seafood, fruits, oil, low­fat milk and cheese. Very sugary desserts are not common in this diet.

Japanese people are some of the longest­living people on the planet, with women up to 87 years old and men up to 80. The Japanese diet is the reason for such lengths of life. The diet has many foods that are low in calories and high in nutrients. Japanese people eat a lot of seaweed, tofu, rice, vegetables and fish. The tradition there is to stop eating when your stomach feels 80 percent full.

However, French people eat fatty foods but do not get fat. And they live a long time. This phenomenon is called the "French Paradox". The reason why the French eat fatty foods without getting fat may be simple. They eat less. Serving sizes in French restaurants and in products sold in stores are smaller than those in most countries. And generally speaking, most French people do not snack. This means they do not eat food between meals.

Chien-Shiung Wu was a Chinese-American particle and experimental physicist who made significant contributions in the fields of nuclear and particle physics. She is best known for conducting the Wu experiment, which proved that parity (对称) is not conserved. This discovery resulted in her colleagues Tsung-Dao Lee and Chen-Ning Yang winning the 1957 Nobel Prize in Physics, while Wu herself was awarded the Wolf Prize in Physics in 1978. Her expertise in experimental physics aroused comparisons to Marie Curie.

Chien-Shiung Wu was born in a town of Jiangsu province, China, in 1912. Wu and her father were extremely close, and he encouraged her interests passionately, creating an environment where she was surrounded by books, magazines, and newspapers. Wu received her elementary school education at Mingde Women's Vocational School founded by her father.

Wu left her hometown in 1923 to go to the Suzhou Women's Normal School No 2, which was fifty miles from her home. In an era when "getting married" was considered the best destiny for women, she carved out a new path for herself through her diligent and earnest approach to learning and her thirst for knowledge.

In 1936, Chien-Shiung Wu went to the United States to pursue further studies in atomic physics. It was during this period of her education that she came to know Oppenheimer, who was teaching in the Physics Department. Under the guidance of renowned physicists such as Oppenheimer, Lawrence, and Segre, Chien-Shiung, Wu successfully completed her studies and her doctoral research. Due to the highly sensitive nature of her work, the details of her research were not revealed until the end of World War II.

In 1984, Chien-Shiung Wu returned to China from the United States. At the age of 72, she made a substantial donation of $250,000 to her hometown to support its development. Later, she also became an academician of the Chinese Academy of Sciences.

In 1997, Chien-Shiung Wu passed away. Before her death, she requested to be buried in her hometown of Suzhou. Today, her tombstone in Taicang, Suzhou, bears the inscription: "She was an outstanding global citizen and a forever Chinese."
