My mom takes pride in the fact that I was talking in three and four word sentences before I was ten months old. Some say it's a gift while others simply think I talk too much.

    As my thirties came to a close, I found myself reflecting on my life. I'm very happy and have no significant regrets. However, when I looked back on those times of difficulty, I saw a clear common denominator(特征); I didn't seem to know when to stop talking. Whether it was hurting someone's feelings, or having carelessly told a secret, the incident could have been avoided had I closed my mouth sooner. So I decided to practice the power of quiet.

    To take this step, I needed to understand how people could sit comfortably in a group and not talk. Why does my husband feel completely content to say nothing in a conversation? He's highly intelligent and has wonderful opinions but he'll sit quietly and just listen. Even when he's asked a pointed question, he'll answer with few words while still communicating effectively. What a talent!

    Can you imagine being happy just listening? In surveying those I know who talk less than I do, I got two answers—they either didn't feel confident enough to speak up, or they just didn't feel the need to participate in the conversation. Of course there were other reasons for not talking, but these were the two most popular answers.

    The first one didn't work for me. I'm just fine letting people know what I think about them, and hopefully it will make the conversation much more interesting. The second one didn't work either. I do feel the need to participate. I feel it physically like an electrical pulse through my body; sometimes it's so strong that it causes me to behave badly in the form of interrupting or speaking in an unusually loud voice. I had to look further.

    An interesting thing happened on this journey to the power of quiet. During my weekly yoga class, it came to me like an answer so clear that the words rang in my head like soft, heavenly bells.

    I talked too much so people would know I cared about them. It was my way of taking care of those I love. I decided before my fortieth birthday, that from that day forward, those around me would know I loved them, and cared what they thought and felt, but I was going to practice the power of quiet.

    As my forty-second birthday approaches, I can say that deciding to talk less has been more about focusing on quality rather than quantity. I've found that listening more shows those who I care about that I really do care how they feel. Now when I break in, it means more to them. Oh, sure, I still have my short periods of talking too much, but for the most part this has been one resolution that I can call a success.

    A new American weather satellite could save more lives by better predicting extreme weather conditions. It will be in orbit(轨道）some 36,000 kilometers above Earth's surface. The National Oceanic and Atmospheric Administration, also known as NOAA, has been working with the National Aeronautics and Space Administration (NASA) on the project.

    NOAA officials are calling the new satellite GOES-R. That is short for a much longer name—the Geostationary Operational Environmental Satellite-R Series. NOAA said GOES-R could improve the nation's ability to observe weather conditions and make weather predictions. It said the satellite's operation would lead to more exact and timely weather forecasts watches and warnings.

    The government agency said the satellite will require testing of its six instruments and will be ready to work “within a year."

    "The next generation of weather satellites is finally here." said NOAA Administrator Kathryn Sullivan. She described GOES-R as one of the most complicated Earth-observing machines ever created. Sullivan said its instruments will be able to study Earth five times faster and with four times more detail than any other NOAA satellite currently in operation. She believes this will make the United States an even stronger, more “Weather-Ready" nation.

    A NOAA statement said the greater detail will help improve the agency's study of ocean storms, as well as “the prediction and warnings of severe weather. "In addition, GOES-R will be able to provide improved rainfall estimates (预计), which will lead to more timely and detailed flood warning. The statement also said that GOES-R will give better estimates of wind strength, as well as better measurement of fog, ice or lightning strikes.

    Craig Fugate serves as administrator of the Federal Emergency Management Agency. He says that the GOES-R satellite will improve the ability of people and organizations across America to prepare for, and react to, weather-related disasters.

    Hold your smartphone, smile at the front camera, and click! You get a selfie. There is no doubt that this photo is yours. But if a monkey takes a selfie, does the camera owner have the right to decide how to use it?

    Recently, this question has caused a problem between Wikimedia Foundation, a non-profit organization, and British wildlife photographer David J. Slater.

    In 2011, Slater was visiting a park in Indonesia when a macaque(猕猴) got hold of one of his cameras. “They were quite naughty, jumping all over my equipment,” Slater told The Telegraph, “and it looked like they were already posing for the  camera when one hit the button.” The result was hundreds of monkey selfies. The best of images was a female macaque grinning toothily into the lens.

    This week, the grinning monkey selfie returned to the news when Wikimedia refused Slater's request to take the photos down from Wikimedia Commons, a website that is run by the organization and offers free images.   5

According to Wikimedia, anyone who downloads the monkey selfie, or any of the millions of images on the site, can “copy and use any works here freely as long as they follow what the author says.” The question that arose here was whether Slater, who had not held the camera, set up the shot, or pressed the shutter(快门) button, could be considered the photographer of the monkey selfie. Wikimedia's position on this was clear: as the work of a non-human animal, this photo has no human author who owns the copyright.”

    Only authors of creative works, like a piece of writing or a song, own copyrights. In terms of photos, US copyright law says whoever pushes the button on the camera owns the copyright to the image produced, which means that if tourists ask you to take a photo of them, and you happen to hit the shutter button at the exact moment that Justin Bieber, a Canadian singer, made faces behind them. You, as the photographer, would have the photo's copyright and sell it. The tourists, who own the camera on which the photo was taken and asked you to take the photo don't get the right to use it without you allowing them to. All this has been complicated by the appearance of surveillance cameras(监控摄像头), smart phones, and large-scale photography projects for which assistants often press the shutter button to produce works whose copyrights belong to their boss.

    Slater seems to be thinking along these lines. He says that buying the cameras, spending thousands of pounds to transport himself to Indonesia, and allowing the monkeys to “steal” his cameras makes him the author of the image, regardless of who pushed the button. “In law, if I have an assistant then I still own the copyright,” he told the “Today” Show. “I believe in this case, the monkey was my assistant.”

    If that seems unfair, think about this. If a person left her laptop in a café, and a poet picked it up, opened up a word-processing program, and typed out a poem which turned out to be the best poem of this generation, could she ask for much more than her laptop back?

    The Board Meeting had come to an end. Bob started to stand up and pushed the table, spilling his coffee over his notes. “How embarrassing! I am getting so clumsy in my old age.”

    Everyone had a good laugh, and soon we were all telling stories of our most embarrassing moments. It came around to Frank who sat quietly listening to the others.

    Frank began,“My Dad was a fisherman. He worked hard and would stay out until he caught enough to feed the family. Not just enough for our family, but also for his Mom and Dad and the other kids that were still at home.”

    Frank's voice dropped a bit. “When the weather was bad he would drive me to school. He would pull right up in front, and it seemed like everybody would be standing around and watching. Then he would lean over and give me a big kiss on the cheek and tell me to be a good boy. It was so embarrassing for me. Here I was twelve years old, and my Dad would lean over and kiss me good-bye!”

    He paused and then went on, “I remember the day I thought I was too old for a good-bye kiss. When we got to the school, he had his usual big smile. He started to lean toward me, but I put my hand up and said, 'No, Dad.' It was the first time I had ever talked to him that way, and he had this surprised look on his face. I said, 'Dad, I'm too old for a good-bye kiss. I'm too old for any kind of kiss.' My Dad looked at me for the longest time, and his eyes started to tear. I had never seen him cry. He turned. 'You're right,' he said. 'You are a big boy ... a man. I won't kiss you anymore.'”

    For the moment, the tears began to well up in Frank's eyes. “It wasn't long after that when my Dad went to sea and never came back.”

    I looked at Frank and saw that tears were running down his cheeks. Frank spoke again.“Guys, you don't know what I would give to have my dad give me just one more kiss on the cheek.”

    It started during a yoga class. She felt a strange pull on her neck, a feeling completely foreign to her. Her friend suggested she rush to the emergency room. It turned out that she was having a heart attack.

    She didn't share similar symptoms with someone who was likely to have a heart attack. She exercised, watched her plate and did not smoke. But on reviewing her medical history, I found that her cholesterol (胆固醇) level was sky-high. She had been prescribed a cholesterol-lowering statin (他汀) medication, but she never picked up the prescription because of the scary things she had read about statins on the Internet. She was the victim of fake medical news.

    While misinformation has been the object of great attention in politics, medical misinformation might lead to an increase in deaths. As is true with fake news in general, medical lies tend to spread further than truths on the Internet—and they have very real bad consequences.

    False medical information can also lead to patients experiencing greater side effects through the "nocebo effect (反安慰剂效应) ". Sometimes patients benefit from an intervention (干预) simply because they believe they will—that's the placebo effect (安慰剂效应). The nocebo effect is the opposite. Patients can experience harmful effects because they anticipate them. This is very true of statins. In blinded trials, patients who get statins are no more likely to report feeling muscle aches than patients who get a placebo. Yet, in clinical practice, according to one study, almost a fifth of patients taking statins report side effects, leading many to discontinue the drugs.

    What else is on the fake news hit list? As always, vaccines (疫苗) . False concerns that the vaccine may cause side effects have greatly reduced coverage rates.

    Cancer is another big target for pushers of medical misinformation—many of whom refuse alternative therapies. "Though most people think cancer tumors are bad, they're actually the way your body attempts to contain the harmful cells," one fake news story reads. It warns that prescription medications lead to the uncontrolled cell mutations (变异) .

    Silicon Valley needs to face this problem. I am not a free-speech lawyer, but when human health is at risk, perhaps search engines, social media platforms and websites should be held responsible for promoting or hosting fake information. Meanwhile, journalists should do a better job of spreading accurate information.

Facial expressions carry meaning that is determined by situations and relationships. For example, in American culture the smile is in general an expression of pleasure. Yet it also has other uses. A woman's smile at a police officer does not carry the same meaning as the smile she gives to a young child. A smile may show love or politeness. It can also hide true feelings. It often causes confusion across cultures. For example, many people in Russia consider smiling at strangers in public to be unusual and even improper. Yet many Americans smile freely at strangers in public places (although this is less common in big cities). Some Russians believe that Americans smile in the wrong places; some Americans believe that Russians don't smile enough. In Southeast Asian cultures, a smile is frequently used to cover painful feelings. Vietnamese people may tell a sad story but end the story with a smile.

Our faces show emotions, but we should not attempt to "read" people from another culture as we would "read" someone from our own culture. The fact that members of one culture do not express their emotions as openly as members of another culture, but it does not mean that they do not experience emotions. Rather, there are cultural differences in the amount of facial expressiveness permitted. For example, in public and in formal situations many Japanese do not show their emotions as freely as Americans do. When with friends, Japanese and Americans seem to show their emotions similarly.

It is difficult to conclude about Americans and facial expressiveness because of personal and cultural differences in the United States. People from certain cultural backgrounds in the United States seem to be more facially expressive than others. The key is to try not to judge people whose ways of showing emotion are different. If we judge according to our own cultural habits, we may make the mistake of "reading" the other person incorrectly.
