Two of the hardest things to accomplish in this world are to acquire wealth by honest effort and, having gained it, to learn how to use it properly. Recently I walked into the locker room of a rather well-known golf club after finishing a round. It was in the late afternoon and most of the members had left for their homes. But a half-dozen or so men past middle age were still seated at tables talking aimlessly and drinking more than was good for them. These same men can be found there day after day, and, strangely enough, each one of these men had been a man of affairs and wealth, successful in business and respected in the community. If material prosperity were the chief necessity for happiness, then each one should have been happy. Yet, it seemed to me, something very important was missing, else-there would not have been the constant effort to escape the realities of life through scotch and soda. They knew, each one of them, that their productivity had ceased (停止). When a fruit tree ceases to bear its fruit, it is dying. And it is even so with man.

    What is the answer to a long and happy existence in this world of ours? I think I found it long ago in a passage from the book of Genesis which caught my eye while I was looking through my Bible. The words were few, but they became memorably impressed on my mind. “In the sweat of the face shall you eat the bread.”

    To me, that has been a challenge from my earliest recollections (memories). In fact, the battle of life, of existence, is a challenge to everyone. The immortal words of St. Paul, too, have been and always will be a great inspiration to me. At the end of the road I want to be able to feel that I have fought a good fight, I have finished the course, I have kept the faith.

    Not long ago, a good friend of mine asked me to help him in a halfway house in Nashville. I agreed and made my way there one evening.

    When I got there, I sat with my friend and talked about how he ended up there. As we talked, another man came up, lighting up his cigarette as he sat down. He had dark, leather skin, and looked like he had endured the sun, the rain, and the wind for long, long time. I couldn't tell how old he was, but I was sure that he was younger than he looked.

    Through a bit of conversation, I found out that he had been on the streets for many, many years.

    Without my asking, he started describing life as a homeless man. How he got food; how he stayed warm; how he got money. And he told me something that caught my attention.

    He said, "You want to know how I keep my stuff safe at night?"

    "Sure," I replied.

    "I put it up in the trees."

    "Why is it safe in the trees?" I asked.

"The homeless are always looking for treasure on the ground— coins, something someone's dropped, half-smoked cigarettes. I know if I put my stuff in the trees, they'll never find it because they never look up. Never. "

    Profound words from an unexpected place. And his message is for all of us.

We all have our particular search. We're looking for treasure on this earth. But what we are REALLY looking for is right there above us. There's really nothing we need on the ground.

    In fact, it's surrounding us.

    Freedom of the press is rightly protected in most societies, yet it is just this protection that sometimes allows this freedom to be made bad use of. The press has a strong influence which can bring about significant changes to the lives of ordinary people. The story of the first quintuplets(五胞胎) in America clearly showed the power of the press.

    There was a poor family living in Aberdeen, a small town in the U. S. A. Raising five children was already a struggle for the poor parents of this family. When the mother learned that it was another four girls and one more boy that were on the way, she and her husband were shocked beyond belief. Without a doubt, they were going to face even more urgent money problems.

    However, this event changed their lives in ways they had never expected. The day after the birth of the five babies, there were sixty reporters and photographers waiting outside their door. The couple soon made national headlines, for they had become the parents of the first quintuplets in America.

    The family gained fame and money overnight. Newspapers and magazines offered them huge sums of money for the rights to publish their stories as well as their photos. Gifts poured in not only from unknown people, but also from baby food and soap manufacturers who wanted to advertise their products. Though their lives were indeed improved, reporters kept pressing for interviews, which forced the family to hire lawyers to act as spokespeople for them at news conferences.

    Moreover, the birth also brought great changes to Aberdeen. A new highway had been developed, since this town was likely to attract thousands of visitors. Even the name of the town on the road signs was changed to "Quint-City, U.S.A." Locals also discussed the possibility of setting up a "quint museum" to satisfy the curiosity of the public and to protect the family from gossipy visitors at the same time.

    While the babies were still quietly sleeping in the hospital, their parents began paying the price for fame. It would never again be possible for them to lead normal lives. The town itself received so much attention that almost each of the locals there was affected more or less. This was the power of the press, but such power could easily be misapplied.

    At first, Michael Surrell didn't see the black smoke or flames shooting from the windows of his neighbors' home. Then they got a call from one of his daughters: "The house next door is on fire!" He went over and saw three women crying madly on their porch (门廊).

    "The baby's in the second floor!" one of the women cried. Though the fire department had been called, Surrell, then 64, bravely ran inside. "The baby" was Tiara Roberts, the woman's granddaughter and a playmate of Surrell's three youngest kids.

Entering the burning house was like "running into a bucket of black paint," Surrell says. The thick smoke caused him to stumble blindly around, burned his eyes, and made it impossible to breathe. The conditions would have been dangerous for anyone, but for Surrell, who has chronic obstructive pulmonary disease(慢性阻塞性肺病), they were life-threatening.

    Taking a deep breath, he moved around in the overwhelming darkness. Because the house had a similar layout to his, he found the stairs and made it to the second floor. Then he heard a soft but clear moan. Still unable to see, Surrell fell to his knees on the hot wood floor. He crawled toward the sound, feeling around for any sign of the girl. Finally, he touched something. A shoe, then an ankle. He pulled Tiara toward him, scooped her into his arms and stood. Turning, he fought through the smoke and ran blindly into the blackness…

    Surrell woke up in the hospital a couple of days later and spent over a week in the hospital. Tiara was released from the hospital after a few days. The fire worsened Surrell's pulmonary condition, and he feels the effects even two years later. As a result, he takes extra medication that helps open his airways. "It's a small price to pay," he says. "I'd do it again in a heartbeat. I wouldn't give it a second thought."

    Scientists around the world are striving for effective detection of cancer in the early stages, which is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body, and a Chinese scientist may have found a quick way of knowing whether malignant tumors (恶性肿瘤) exist in a patient's body, with just one drop of blood.

    Malignant tumors in early phases can be cured. However, it's extremely difficult to be aware of cancer in its early stages, as patients don't show obvious symptoms and thus it can only be found in its later stages, which is already too late, so to detect cancer early remains a global challenge for scientists.

    Back in 1989, scientists have found a kind of heat shock proteins (HSP), named Hsp90α, which existed in human bodies and can be used as a cancer biomarker detection kit. Scientists around the globe have been working on it since then, and more than 10, 000 journals have been published on accredited magazines, yet no one has actually turned their research results into medical products.

    However, Luo Yongzhang and his team in Tsinghua University's School of Life Sciences in Beijing seemed to have cracked the code, after working on the problem since 2009.The team has produced an artificial Hsp90α protein for clinical use that gains structural stability by regrouping proteins. The test kit can diagnose multiple kinds of cancer by analyzing a drop of human blood. This means they are able to "create" the protein, in any quantity, and at any time they wish to.

    The kit has since been used in clinical trials involving 2, 347 patients at eight hospitals in China. It was the first clinical trial in the world to test if the protein could be a useful tumor biomarker for lung cancer, and it succeeded. Now, the kit has been approved to enter the Chinese and European markets, 24 years after Hsp90α was discovered.

A seismic (地震的；重大的) shift in climate science might be heating up.

New research shows that sound waves, produced by earthquakes can be used to measure temperatures in the ocean which traps 90% of the heat Earth absorbs from the sun，making long-term changes in ocean warmth, a major factor in how the world might respond to global warming.

For years the main approach of measuring ocean temperature has been Argo, an array (阵列) of 4000 automatic floats, which drifts the globe, sampling ocean water and measuring its temperature. Yet Argo measurements stop at 2000 meters.

The new technique called "Seismic Ocean Thermometry", would be especially useful in detecting long-term changes in ocean temperatures deeper than Argo's reach.

"Ocean Acoustic Tomography", the basis for the current research, was first tested nearly 30 years ago. The initial studies created sound waves artificially, basically increasing the volume on giant underwater speakers. Scientists measured the sound's travel time from the speakers to receivers thousands of kilometers away. Because ocean temperatures affect the speed of the waves, the researchers could calculate average temperatures along their paths. But some believed the noise was a threat to ocean life and the technique never took off.

The new study instead uses a natural sound source for investigation: earthquakes making a low, continuous noise beneath the seafloor off the coast of Sumatra that drum up sound waves in the ocean. On the shores of the Chagos Islands in the East Indian Ocean, between 2005 and 2016 Seismic Station Diego Garcia recorded seismic waves produced by those earthquakes. Some of those waves created physical changes in land and sea as they traveled. Others were sound waves or T waves that moved through the deep ocean, delivering valuable data about ocean temperature.

12 years of data coupled with mathematical models pointed to a temperature change of roughly 0.044 degrees per decade, a trend larger than those predicted by Argo. The findings suggest that Seismic Ocean Thermometry is a feasible method to measure changes in ocean temperature. Further data from other regions of the globe and other timeframes would help improve the warning models and predictions.

And in future studies the researchers plan to listen directly for sound waves, using a network of hydrophones, microphones which detect sound waves under water. Sound waves set the tone for a deep dive into our warming oceans even if they fail to reach 60000 miles under the sea?
