"Some secrets are hidden from health," wrote John Updike in his poem "Fever".

    I have experienced the truth of Updike's observation. My excellent health kept me from seeing some things—things that became secrets of sort.

    One relates to my son Chris. When I lost my health in March, I discovered something I had missed about him.

    Christopher has been a scholar and athlete through high school. He has behaved responsibly, engaged in community service. He has had an impressive peer group of serious students.

    While I saw these things, I had missed before what I experienced while in hospital. Early on, Christopher offered the clearest and most forceful words about my need to be positive and to fight acute leukemia(急性白血病). He never left the room after a visit without making me promise that I would be mentally tough and positive.

    During the first week, he showed his own mental toughness, researching leukemia and learning what the chances were. He even stopped my doctor outside the room, introduced himself and asked directly what he thought of my chances. He processed the answer without overreaction.

    Christopher did admonish(劝告) me against my choice of words the first week at home. I had moved back into my room from weighing myself, discovering a thin figure I did not know. I announced to him and my wife, “dead man walking”. I thought it was a way to lighten the obvious. He saw it as negativity and was strongly against such thinking and talking.

    When I resisted taking medicine sometimes, Christopher formed a “good-cop-bad-cop” team with his mother. Betsy gently and patiently encouraged. He directly and forcefully insisted. He always made the logical arguments for why I needed to take some awful pills.

    My health had hidden something from me; my ill-health helped me to see it.

    Life is full of funny moments, and not just for humans.

    Over the years, studies by various groups have suggested that monkeys, dogs and even rats love a good laugh. People, meanwhile, have been laughing since before they could talk.

    Jaak Panksepp, a professor at Bowling Green State University, US, said he would not be surprised if positive feelings could be produced in some animals. Dolphins, for example, have long attracted animal researchers because of the complex (复杂的) ways in which they communicate: a rich variety of sounds of different rhythms. A decade ago, researchers studying dolphins at the Kolmarden Wildlife Park in Sweden noticed a set of sounds the dolphins made during play-fighting. They concluded that the purpose of the sound was to suggest that the situation was pleasant and to prevent it from a real fight.

    Panksepp has even seen evidence of joy in crayfish (小龙虾). When given small amounts of drugs such as cocaine (可卡因) in a certain place, they appear to connect that location with pleasure. “Given the chance, they will always return to that place, perhaps in the hope of getting more,” he says. Panksepp wasn't sure it equals the same happiness that humans get from cocaine, but said it “could be in the same evolutionary category”.

    More studies are needed to really understand animals' laughter. Strangely enough, the answers may help with our own desires for cures for mental illnesses. Panksepp's experiments may soon lead to a new antidepressant (抗抑郁) drug that works by using the pathways in the brain behind positive feelings and joy. Perhaps pleasure and laughter in the animal world will help solve the depression in our own species one day.

    Gravity signals that race through the ground at the speed of light could help seismologists(地震学家) get a better handle on the size of large, destructive quakes soon after they hit，a study suggests. The tiny changes in Earth's gravitational field, created when the ground shifts, arrive at earthquake monitoring stations well before earthquake waves.

    “The good thing we can do with these signals is have quick information on the magnitude (震级) of the quake,” says Martin Vaillée, a seismologist at the Paris Institute of Earth Physics.

    Earthquake equipment in China and South Korea picked up gravity signals immediately after the magnitude-9. 1 Tohoku earthquake that destroyed parts of Japan in 2011. The signals appear as tiny accelerations on earthquake-recording equipment, more than a minute before the seismic waves show up.

    “We can look before the earthquake waves arrive,” says Vallée. “If we see nothing, we can say that the quake that made these was maybe large, but not huge. If we see the signals, it means we really have a very big quake. ”

    Had seismologists been monitoring for gravity changes, they might have realized sooner just how big the Tohoku earthquake was. A small increase in an earthquake's magnitude means a large change in the energy released by the quake-and the destruction expected. That information is important for emergency responders as they decide what resources to arrange.

    It'll be a major contribution if gravitational waves can beat down the time needed to know that a big earthquake is big. But much work remains before gravity signals can be considered a reliable tool in the vital minutes after a big quake. A few extra minutes of warning can save lives, particularly in coastal areas where people can flee ahead of an incoming tsunami.

    I sat with my friend in a well-known coffee shop in a neighboring town of Venice. As we enjoyed our coffee, a man called the waiter and placed his order, “Two cups of coffee, one on the wall.” We got interested and observed that he was served with one cup of coffee but he paid for two. As soon as he left, the waiter attached a piece of paper to the wall saying “A Cup of Coffee.” Similar occasions took place twice while we were there. It seemed that this gesture was quite normal at this place. However, it was something unique and confusing for us.

    After a few days, when we again enjoyed coffee there, a man entered. The way this man was dressed did not match the standard or the atmosphere of this coffee shop. Poverty was evident from his looks. As he seated himself, he looked at the wall and said, “One cup of coffee from the wall.” The waiter served coffee to this man with respect and dignity. The man had his coffee and left without paying. We were amazed to watch all this when the waiter took off a piece of paper from the wall and threw it in the dustbin.

    Now it was no surprise for us; the matter was very clear. The great respect for the needy shown by people in this town moved us to tears.

    Coffee is not a necessity. However, the point is that when we take pleasure in any blessing, maybe we also need to think about those people who also appreciate that specific blessing but cannot afford.

    Note the waiter, who gets the communication going between the affording and the needy with a smile on his face. Think about the man in need: he enters the coffee shop without having to lower his self-dignity; he has a free cup of coffee without asking or knowing about who has given this cup of coffee to him; he only looked at the wall, placed an order for himself, enjoyed his coffee and left. Besides, we need to remember the role played by the wall that reflects the generosity and care of people in this town.

    To improve Chinese on our campus, several programs will be organized. Here is some information.
