Cancer is a leading cause of death around the world.

    When it comes to cancer, the sooner you know you have it, the better your chances of surviving are.

    A new blood test could change the way doctors and researchers find cancer in patients. Researchers say the test could provide some hints of the early forms of the disease.

    Gareth Jenkins is a professor at the University of Swansea. He says he and his team did not look for cancer. They instead looked for a by-product of cancer, mutated (突变的) red blood cells. They looked for, what Jenkins calls, the collateral (附带的) damage of cancer—the damage left by the disease.

    “In this blood test we don't measure the presence of cancer，we measure the presence of mutated red blood cells which are the collateral damage that occurs—a by-product of the cancer developing.''

    The researchers used normal laboratory equipment to perform the tests. This equipment looks for changes in the structure of millions of red blood cells. Those mutated cells lack a surface protein (蛋白质) that healthy cells normally have.

    “The goal of the test is looking for very rare cells which have picked up a mutation. The number of mutated red blood cells in a healthy person is around 5 or so mutated cells per million; so, you have to look at millions of red blood cells to discover those rare events. The number increases in cancer patients—it goes up to 40 or 50 on average.”

    The researchers tested blood from about 300 people, all of whom have cancer of the esophagus (食管). Patients with esophageal cancer have high levels of mutated red blood cells. Jenkins says that at this point he is not sure if other cancers would produce similar results.

    The hope is that the new test could one day become part of commonly used medical methods to find out if a person has cancer. These new technologies could save millions of lives.

    A dog can keep us company. Sweetie is a big dog who spends every Friday of the month in the Children's Area of our local library. Earlier today, I was so lucky to be nearby when she was partnering with a boy who was reading a mystery of Magic Tree House. Every time Sweetie listened to the boy reading the most challenging words, she would softly lick（舔）his hand which was holding the book. With his mom in the background, Sweetie and the young boy shared a 10-minute happy partnership, and he was rewarded by Sweetie's great attention to his every word.

    Next Sweetie had an appointment with the twins who took turns reading poetry. With each girl giggling over the funny words, Sweetie was also smiling with her tongue dropping a bit as they each read. After the 10-minute interaction was done, each girl gave Sweetie a gentle hug and were rewarded by Sweetie's foreleg bow.

    In speaking with Sweetie's owner and transportation “captain”, I learned that Sweetie had been specially trained to work as a service dog. She has retired（退休）after a career of wonderful service, and now she is “in her sunset years” in her service at the library.

    Sweetie has a special resting carpet behind the scenes in the Children's Area, so that she can refresh herself with fresh water and some food when she is tired and hungry. This is Sweetie's third summer that she has been the “regular” partner. Oh Fridays from 2 pm~4 pm, Sweetie is ready to listen and act as a devoted partner.

    Everybody hates rats (big mice). But in the earthquake capitals of the world — Japan, Los Angeles, Turkey — rats will soon be man's best friends.

    What happens after an earthquake? We send in rescue dogs. Why? Because they can smell people. Dogs save lives. They help rescuers to find living people. But dogs are big and they can't get into small spaces. So now a new research project is using a smaller animal to save lives: the rat.

    How does it work? First, the rat is trained to smell people. When this happens, the rat's brain gives a signal (信号)．This is sent to a small radio on its back, and then the rescuers follow the radio signals. When the rat's brain activity jumps, the rescuers know that someone is alive. The rat has smelled that person.

    Although there are already robots which can do this job, rats are better. Christian Linster at Cornell University, New York, says, "Robots' noses don't work well when there are other smells around. Rats are good at that." Rats can also see in the dark. They are cheaper and quicker to train than dogs, and unlike robots, they don't need electricity!

    The "rat project" is not finished, but Julie Ryan of International Rescue Organization in Scotland says, "It would be wonderful. A rat could get into spaces we couldn't get to, and a rat would get out if it wasn't safe." Perhaps for the first time in history, people will be happy to see a rat in a building (but only after an earthquake, of course).

    On Monday, my classmates and I heard that our astronomy teacher's mother had died. We were surprised that he was still teaching in school. My best friend was telling me that the teacher was trying to forget the pain of losing his mother and trying to be strong in the middle of teaching.

    The teacher was such a warm-hearted person and we figured that we should give him a lot of love and good cheer. That night after school, my best friend and I thought about our teacher as well as his beloved mother and then we came up with an idea.

    When we went back to school yesterday, we gave him cheer-up cards which we had taken time to decorate with flowers, hearts and peace signs. As we handed the cards to him, we could both see the light in his eyes. The smiles on his face showed how much he appreciated what we did for him. The whole atmosphere was very warm and loving, and it's hard to express in words.

    This morning, when we both went to see the teacher again, he was so happy, and gave us both a hug. This made us feel that we just might have made his day, and that he was going to be okay.

    With that, I want to remind you to take the time to smile at the ones you love, be extra generous with hugs, kisses, things of that lovely nature! Life is so precious (宝贵的), so let us be happy and enjoy the gift of life.

Internet time tied to teen depression(抑郁) symptoms

    Spending time online is normal behaviour for teenagers. But too much Internet use by teens —or too little, for that matter —might be related to depression, a new study finds.

    The findings, reported in the journal of Pediatrics, do not mean that the Internet is to blame. For one, teens in the study who spent no time online were also at increased risk of depression symptoms. Instead, the researchers say that both heavy Internet use, and non-use, could serve as signals that a teenager is having a hard time.

    For the study, Dr. Pierre-Andre Michaud and his colleagues at the University of Lausanne, Switzerland, surveyed 7,200 individuals aged 16 to 20 about their Internet use.

    Those who were online more than two hours per day were considered "heavy" Internet users, while those online anywhere from several times per week to two hours per day were considered "regular" users.

    The teenagers also answered a number of health-related questions, including some standard questions about "depressive tendencies" that gauge(判定) how often a person feels sad or hopeless. Compared with regular Internet users, the study found, kids who were heavy users or non-users were more likely to be depressed or very depressed.

    Among male teens, heavy users and non-users were both around one-third more likely to have a high depression score, compared to "regular" users. Among girls, heavy Internet users had an 86 percent greater chance of depression, while non-users had a 46 percent greater likelihood compared to regular users.

    That was with factors like family income and any chronic health problems taken into account.

    Since teenagers typically go online to contact with friends, the researchers speculate(推测) that those who are never online may be more socially isolated.
