If you want to get something done, you might want to put your mobile phone back in your pocket. Researchers have found that the mere presence of a phone is distracting (分心) — even if it is not your own. And the devices (设备) are likely to distract you, even if they are not ringing or “pinging” with text messages. People asked to carry out electronic tests of their attention spans were found to perform worse when a mobile phone was present than other people performing in the presence of a paper notepad.

    Scientists from Hokkaido University in Japan said that their findings show that it is harder to concentrate when one of the electronic devices is present. The effect was most marked on people who are not regular users of phones. In tests on 40 undergraduates. Associate Professor Junichiro Kawahara and a colleague divided the subjects into two groups — one asked to carry out tests in the presence of an Apple iPhone next to a computer monitor, and the other in the presence of a notebook.

    The test involved asking the participant to search for a particular character among a mess of other characters on the screen. Researchers measured the time it took to find the target. The results of the experiment found that those with the mobile phone took longer to find the character, indicating that participants were automatically distracted by the presence of the phone. The researchers suggest that people are drawn to the presence of a mobile phone, although there are individual differences in how one attempts to ignore it. In conclusion. Professor Kawahara said. “The mere presence of a mobile phone was a distraction among infrequent internet users.”

    Another finding is that listening to one half of a mobile phone conversation also distracts people, and other studies have found that placing a mobile phone in view has a negative impact on the quality of face-to-face communications. Holding a mobile phone makes you less likely to get a fair hearing from others.

    A fourth-grade teacher allowed one of her students to shave her head in the schoolyard, after bullies（仗势欺人者）teased him about his own short buzz cut（短寸头发型）. Tori Nelson got the idea after noticing that Matthew Finney, a shy boy from her homeroom at Winlock Miller Elementary School in Washington state, was standing outside his classroom crying and wearing a winter hat.

    Ms. Nelson could see the back of his neck had been shaved, and since Matthew usually had very thick brown curly hair, she realized that he'd had a haircut over the weekend. She asked him what was wrong, and he said he'd gotten a buzz cut for the summer. But this morning, a fifth grader on the bus made fun of him, and he didn't want to come to class and get teased by other kids. Ms Nelson tried to convince Matthew to come inside, but since school rules prohibit kids from wearing hats indoors he refused – explaining that he was afraid of showing his haircut to the other children in case they also made fun of him.

    Finally I said: "If you take off your hat and come to class, I'll let you give me a buzz cut, too," 'Ms Nelson told Yahoo Parenting. I figured it's just hair, and mine is already short anyway. I might as well get it shorter in time for the warm weather.'

    Matthew excitedly took her up on the offer, and Ms Nelson and another teacher gathered all the fourth graders together during break time. A school employee brought in scissors, which Matthew used to the cheers of his classmates, excitedly watching as his teacher's hair fell away onto the ground in the schoolyard.

    'It was a lot of fun for the kids, and it helped Matthew feel better about himself,' said Ms Nelson.' You have to do what it takes to reach children. Teaching isn't just about reading and writing, it's about self-esteem and accepting differences.'

    Are you interested in helping your child continue his or her education beyond the typical school day? If so, then educational programs for kids may be what you're looking for.

    Where to Find Educational Programs?

    Many kids who are struggling in school may benefit from an after-school tutoring session or homework club. Check with your child's school, your local library or the park district for a list of available programs. You can also check with the local Boys and Girls Club, YMCA, church or youth center. Depending on your child's interests and strengths, consider art, community service, drama, music, creative writing, sports, cooking or environmental programs.

    What Educational Programs Are Provided by Organizations?

    The organizations mentioned above provide educational programs for kids, such as a community your child can be a part of and programs that focus on education, health, leadership, recreation and fitness.

   Another possibility is the Boy Scouts of America or the Girl Scouts. These are two separate organizations that can potentially provide your child with a sense of accomplishment, self-confidence and belonging. Both organizations will provide your child with many learning experiences and activities both indoors and outdoors.

    What Kind of Program Is Best for My Child?

    The type of educational program that's best for your child is subjective and based on many factors, including your child's age. If your child is in primary school, educational programs can help him or her develop as a person and gain leadership skills, a sense of self-worth and the ability to cooperate with others. By the time your child is in high school, his or her involvement with educational programs and other extracurricular activates can be key elements when your child is applying to college.

    When you help your child to pick an educational program, carefully consider what your child needs and what every option offers.

    Psychology has a new application in the field of medicine. Many doctors, together with their patients, are looking for alternative methods of treatment of physical problems. In large hospitals, modern therapy(疗法)seems to focus on the physical disease. Patients may feel they are treated like broken machines. Some doctors have recognized this as a problem. They are now using psychological therapy, in which the patient is working with the doctors against the disease with the help of medicine. The patient does not wait for the medicine and treatment to cure him or her, but instead the patient joins in the fight.

    The doctor knows that a disease affects a patient's body physically. The body of the patient changes because of the disease. He is not only physically affected, but also has an emotional response to the disease. Because his mind is affected, and his attitude and behavior change. The medical treatment might cure the patient's physical problems, but the patient's mind must fight the emotional ones. For example, the studies of one doctor, Carl Simonton, M.D., have shown that a typical cancer patient has predictable attitudes. She typically feels depressed, upset, and angry. Her constant depression makes her acts unfriendly toward her family, friends, doctors, and nurses. Such attitudes and behaviors prevent recovery. Therefore, a doctor's treatment must help the patient change that. Simonton's method emphasizes treatment of the "whole" patient.

    The attitude of a cancer patient receiving radiation therapy, an X-ray treatment, can become more positive. The physician who is following Simonton's psychological treatment plan suggests that the patient imagine that he or she can see the tumor(肿瘤)in the body. In the mental picture, the patient "sees" a powerful beam of radiation like a million bullets of energy. The patient imagines the beam hitting the tumor cells and causing them to shrink. For another cancer patient, Dr. Simonton asks him to imagine the medicine going from the stomach into the bloodstream and to the cancer cells. The patient imagines that the medicine is like an army fighting the diseased cells and sees the cancer cells gradually dying and his blood carrying away the dead cells. Both the medical therapy and the patient's positive attitude fight the disease.

    Doctors are not certain why this mental therapy works. However, this use of psychology does help some patients because their attitudes about themselves change. They become more confident because they use the power within their own minds to help stop the disease.

    Another application of using the mind to help cure disease is the use of suggestion therapy. At first, the doctor helps the patient to concentrate deeply. The patient thinks only about one thing. He becomes so unaware of other things around him that he is asleep, or rather in a trance(催眠状态). Then the physician makes "a suggestion" to the patient about the medical problem. The patient's mind responds to the suggestion even after the patient is no longer in the trance. In this way, the patient uses his mind to help his body respond to treatment.

    Doctors have learned that this use of psychology is helpful for both adults and children. For example, physicians have used suggestion to help adults deal with the strong pain of some disease. Furthermore, such treatment may help the patient with a chronic diseases. Suggestion has been used to change children's habits like nail­biting, thumb­sucking, and sleep­related problems.

    Many professional medical groups have accepted the medical use of psychology and that psychology has important applications in medicine.

    The earliest known copy of Leonardo da Vinci's Mona Lisa—thought to have been painted at the same time as the original masterpiece—has been discovered at the Prado Museum in Madrid, Spain. The work offers art-lovers an attractive clue to what the model for the world's most famous painting really looked like. Controllers of the museum found the picture hidden beneath layers of paints during restoration work on a picture initially thought to have been a later replica(exact copy) of the Mona Lisa.

    The restored version shows the same woman that Leonardo depicted (描画), against a landscape similar to that shown in the background of the original, which now hangs in the Louvre in Paris. And while the features of Leonardo's Mona Lisa have been dulled by centuries of dirt and layers of cracked paints—which are unlikely ever to be removed—in the recently-rediscovered copy, she appears fresher-faced and younger than her better-known "twin".

    News of the find was revealed at a meeting at London's National Gallery, linked to its "Leonardo da Vinci: Painter at the Court of Milan" exhibition. "This sensational (轰动的) find will transform our understanding of the world's most famous picture," the Art Newspaper reported, adding that the clues found on the Madrid version suggest that the original and the copy were begun at the same time and painted next to each other, as the work went on.

    Miguel Falomir, manager of Italian painting at the Prado, told reporters that expert analysis suggested a strong link between Leonardo and the artist who painted the copy. "The painting was done in the painter's own workshop," he said. "It is absolutely consistent with Leonardo's work, but Leonardo didn't actually do any work on it himself."

As the pandemic makes clear, cities are possibly humanity's greatest invention, but cities with huge populations also make us easily suffer from the rapid spread of disease. Yet humans aren't the only species that face this problem. Honeybees have lived social lives for tens of millions of years, making them some of the most experienced in the battle against infection. And over time, natural selection has given them quite a few impressive strategies for reducing transmission within bee groups.

However, these strategies are not enough to prevent every threat. Honeybees are battling their own global disease, for which they were totally not prepared. A parasitic mite (寄生螨) originally existed only in the groups of Asian honeybees, but later jumped to infect Western honey bees. Today, it has spread to every region where honeybees are kept except Australia and a handful of remote islands, quickly becoming a global disease of the bees.

If left untreated, a group of bees will typically die from the mites within two years. These infections, plus farm chemicals and poor nutrition, have forced beekeepers to struggle to keep their bees alive. Of the 2.6 million honeybee groups in the US, over half of them have parasitic mite.

And that's only the count of those bees that are tested and reported; the actual numbers are likely much higher. Beekeepers have still managed to slowly increase the number of groups they keep, on average, but at a much higher cost.

Western honeybees did not grow with parasitic mite, and the Western bees lack the behavioral features those Asian honeybees have, like permanently burying the members infested by parasitic mite and, perhaps the most extreme strategy, where the bees are so sensitive to parasitic mite that they completely die as soon as infected, sacrificing themselves to prevent the mite from reproducing.
