When her five daughters were young, Helene An always told them that there was strength in unity (团结). To show this, she held up one chopstick, representing oneperson. Then she easily broke it into two pieces. Next, she tied several chopsticks together, representing a family. She showed the girls it was hard to break the tied chopsticks. This lesson about family unity stayed with the daughters as they grew up.

Helene An and her family own a large restaurant business in California. However, when Helene and her husband Danny left their home in Vietnam in 1975, they didn't have much money. They moved their family to San Francisco. There they joined Danny's mother, Diana, who owned a small Italian sandwich shop. Soon afterwards, Helene and Diana changed the sandwich shop into a small Vietnamese restaurant. The five daughters helped in the restaurant when they were young. However, Helene did not want her daughters to always work in the family business because she thought it was too hard.

        Eventually the girls all graduated from college and went away to work for themselves, but one by one, the daughters returned to work in the family business. They opened new restaurants in San Francisco and Los Angeles. Even though family members sometimes disagreed with each other, they worked together to make the business successful. Daughter Elisabeth explains, "Our mother taught us that to succeed we must have unity, and to have unity we must have peace. Without the strength of the family, there is no business."

        Their expanding business became a large corporation in 1996, with three generations of Ans working together. Now the Ans' corporation makes more than $20 million each year. Although they began with a small restaurant, they had big dreams, and they worked together. Now they are a big success.

    In 1977, a dead author of detective stories saved the life of a 19-month-old baby in a most unusual way. The author was Agatha Christie, one of the most successful writers of detective stories in the world.

    In June 1977, a baby girl became seriously ill in Qatar, near Saudi Arabia. Doctors were unable to find out the cause of her illness with confidence, so she was sent to Hammersmith Hospital in London. She was then only semi-conscious and on the "Dangerously Ill" list. A team of doctors hurried to examine the baby only to discover that they, too, were confused by the very unusual symptoms (症状). While they were discussing the baby's case, a nurse asked to speak to them.

    "Excuse me," said Nurse Marsha Maitlan, "but I think the baby is suffering from thallium (铊) poisoning(中毒)."

    "What makes you think that?" Dr. Brown asked. "Thallium poisoning is extremely rare."

    "A few days ago, I was reading a novel called A Pale Horse by Agatha Christie," Nurse Maitlan explained. "In the book, somebody uses thallium poison, and all the symptoms are described. They're exactly the same as the baby's."

    "You're very thoughtful and you may be right," another doctor said. "We'll carry out some tests and find out whether it's thallium or not."

    Tests showed that the baby had indeed been poisoned by thallium, a rare metallic substance(物质) used in making special glass. Once they knew the cause of the illness, the doctors were able to give the baby the correct treatment. She soon recovered and was sent back to Qatar. Later it was reported that the poison might have come from an insecticide (杀虫剂) used in Qatar.

    Here's an idea whose time has come: A flu shot that doesn't require an actual shot.

    For the first time, researchers have tested a flu vaccine patch (疫苗贴) in a human clinical experiment and found that it delivered as much protection as a traditional injection with a needle. Doctors and public health experts have high hopes that it will increase the number of people who get immunized (免疫的) against the flu.

    Seasonal flu is responsible for up to half a million deaths around the world each year according to the World Health Organization. A team led by Georgia Tech engineer Mark Prausnitz has come up with an alternative method that uses “microneedles”. These tiny needles are so small that 100 of them, arranged in order on a patch, can fit under your thumb (拇指). Yet they're big enough to hold vaccine for three types of flu.

    None of the study volunteers had serious side effects. The groups that got patches had mild skin reactions that were not seen in the regular needle group, while the volunteers in the regular needle group were more likely to experience pain. Overall, 70 percent of the volunteers who got vaccine patches said they'd rather use them again than get a traditional flu shot. The study authors declared it a success on all fronts.

    The biggest beneficiaries could be people in low- and middle-income countries, where flu vaccines are hard to come by. Reducing pain is nice, but other benefits—the patch costs less, is easier to transport, doesn't require refrigeration, can be self-administered and doesn't cause waste of needles—are even better.

    "Microneedle Patches have the potential to become ideal candidates for vaccination programs," wrote Katja Hoschler and Maria Zambon of Public Health England.

    It's not unusual to see an unreasonable child lying on the ground drumming his heels. Beside him is a desperate mother yelling at the top of her lungs. Raising a well-behaved kid is really a head-scratching thing.

    If you took all the parenting styles around the world and ranked them by their gentleness, the Inuit (因纽特人) approach would certainly rank near the top. All the moms mention one golden role: Don't shout or yell at small children. Inuit's no-yelling policy is their central component to raising cool-headed kids. The culture views scolding, or even speaking to children in all angry voice, as inappropriate, although little kids are pushing parents' buttons.

    Playful "storytelling" is another trick to sculpting kids' behavior. But this storytelling differs hugely from those fairy tales full of moral lessons. Parents "retell" what happened when a boy threw a tantrum(发脾气)by way of what Shakespeare would understand all too well: putting on a "drama". After the child has calmed down, the parents will review what happened when the child misbehaved, usually starting with a question: "Can you show us how to throw a tantrum?" Then the child has to think what he should do. If he takes the bait and performs the action, the mom will ask a follow-up question with a playful tone. For example: "Does that seem right?" or "Are you a baby?" She is getting across the idea that "big boys" won't throw a tantrum.

    Kids' brains are still developing the circuitry needed for self-control. What you do in response to your children's emotions shapes their brains. So next time, seeing your boy misbehave, try using the Inuit's storytelling approach. And don't forget to keep cool. After all, boys will be boys.

    When we see a person in trouble, the first idea that comes to our mind is to lend a hand. But what if we see an animal in trouble, does the same rule apply?

    This question was raised after a group of penguins were saved from an icy gully（峡谷）in Antarctica. It was filmed for the BBC wildlife series Dynasties. The film crew were anxious when they saw that a group of penguins had fallen into a gully and been trapped with their young. They built a slope（斜坡）so that a few of the penguins could save themselves.

    The case has taken the international media by storm. Viewers watching this film let out a sigh of relief. "I'm so glad. I understand not taking action directly, but a helping hand isn't bothering, right?" viewer Kathryn Shaw said on her Facebook.

    However, others think human interference（干涉） is unnatural. "You can't have sunshine throughout your life. To have done anything else would only make matters worse," said the show's creator David Attenborough, according to The Times.

    In this case, however, Mike Gunton, the executive producer of the series, said that this was a one­off situation. "There were no animals going to suffer by interfering. You weren't touching the animals and it was just felt by doing this... they had the chance not to have to keep slipping down the slope," he told the BBC.

    Such cases are familiar to Paul Nicklen, wildlife photographer for National Geographic. He told Metro, "If it's ever a predator（捕食者）situation, no matter how gut­wrenching, you stay out of the way. Even when you're watching a male polar bear eat a baby bear."

    "There's no rule book in those situations. You can only respond to the facts that are right there in front of you," Will Lawson, the show's director, told Daily Mail.

It is William Shakespeare, the great coiner, who is given credit for the word. Coriolanus, one of his characters, compares going into exile (流放) to a "lonely dragon" retiring to his cave. He was talking about a physical state: someone who was lonely was simply alone. Then, thanks to the Romantic poets, the word took on emotional meanings. Loneliness became a condition of the soul. For William Wordsworth, who famously "wandered lonely as a cloud", the natural world offered an escape from negative feelings of loneliness—a host of flowers could provide "cheerful company". Today, loneliness is often seen as a serious public-health problem, creating the feeling of disconnection.

In his book Solitude, Netta Weinstein, a psychology professor wonders the rewards of time spent alone. He begins with an account of stories of solitude created by figures such as Michel Montaigne, a writer, and Edward Hopper, a painter. Netta then draw on laboratory work, interviews and surveys to clarify how being alone really affects the human mind.

It is common to treat loneliness and solitude as synonyms (同义词) but they are not. The author suggests that what is negatively described as one state can be positively expressed as the other. Loneliness, often perceived as negative, can potentially be transformed into a positive experience of solitude. To this end he emphasizes how being alone can help restore people and offers practical advice. In a noisy world, he argues, people should make time to be alone, away from attention-grabbing motives.

The book's interviewees mostly regard a lack of company as a contributor to autonomy. But this depends on whether solitude is desirable or not. Enforced solitude, such as that experienced by prisoners, typically leads to nothing but suffering. Elective solitude, by contrast, affords space for self-reflection. It can open the door to "peak experiences" such as wonder, harmony, and happiness. In a highly-connected digital age, however, many readers do not fancy their chances of ever taking a long enough break to have such experiences.
