    Why elephants rarely get cancer is a mystery that has confused scientists for decades. A study was led by researchers at Huntsman Cancer Institute (HCI) at the University of Utah and Arizona State University, including researchers from the Ringling Bros. Center for Elephant Conservation may have found the answer. According to the results, elephants have 38 additional modified copies of a gene (基因) that encodes p53, a well-defined tumor (肿瘤) suppressor, as compared to humans, who have only two. Further, elephants may have a more powerful mechanism for killing damaged cells that are at risk for becoming cancerous. In isolated elephant cells, this activity is doubled compared to healthy human cells, and five times that of cells from patients with Li-Fraumeni Syndrome, who have only one working copy of p53 and more than a 90 percent lifetime cancer risk in children and adults. The results suggest extra p53 could explain elephants' increased resistance to cancer.

    "Nature has already figured out how to prevent cancer. It's up to us to learn how different animals overcome the problem so we can adapt those strategies to prevent cancer in people," says co-senior author Joshua Schiffman, M.D., pediatric oncologist (肿瘤学家) at Huntsman Cancer Institute, University of Utah School of Medicine, and Primary Children's Hospital.

    According to Schiffman, elephants have long been considered a walking problem. Because they have 100 times as many cells as people, they should be 100 times more likely to have a cell slip into a cancerous state and cause the disease over their long life span of 50 to 70 years. And yet it's believed that elephants get cancer less often, a theory confirmed in this study. Analysis of a large database of elephant deaths estimates a cancer death rate of less than 5 percent compared to 11 to 25 percent in people.

    Booking a trip on an online travel site is convenient, but comes with its own set of problems.

    They know who's going to spend more.

    Last year, US travel research company Orbitz tracked people's online activities to test out whether Mac users spend more on travel than PC users. It turns out that on average, Mac users lay out US $20-30 more per night on hotels. As a result, online travel sites show these users more expensive travel options first. To avoid paying more, sort results by price.

    Their software doesn't always link to the hotel's system.

    A guaranteed reservation is almost impossible to come by anywhere — but the risk of your flight or hotel being overbooked increases with third-party providers. The middleman's software isn't immune(防护作用的) to system errors, so always call the hotel or airline to make sure your booking was processed.

    Don't be fooled by packages: Often, they're low-end items grouped together.

    Ever notice how travel sites recommend a hotel, a rental car, and tour package all in one click? These deals usually feature travel that no one wants, like flights with multiple layovers(中途停留). Check the fine print.

    Once your trip is purchased, you're on your own.

    An online travel agency can't provide assistance the same way an agent can if a flight is cancelled or a room is substandard. Basically, when you arrive at the airport or hotel, you're just another customer who booked at the lowest rate.

    Traffic jam and cities, it seems go hand in hand. Everyone complains about being stuck in traffic, but, like the weather, no one seems to do anything about it. In particular, traffic engineers, transportation planners, and public officials responsible for transportation systems in large cities are frequently criticized for failing to solve traffic jam.

    But is traffic jam a sign of failure? Long lines at restaurants or theater's box offices are seen as signs of success. Should transportation systems be viewed any differently? I think we should recognize that traffic jam is an unpreventable by-product of successful cities and view the “traffic problem” in a different light.

    Traffic jam occurs where there are lots of people but limited spaces. Culturally and economically successful cities have the worst traffic problems, while decaying cities don't have much traffic. New York and Los Angeles are America's most crowded cities. But if you want access to major brokerage houses(经济行), you will find them easier to reach in crowded New York than in any other large cities. And if your company needs access to post-production film editors or satellite-guidance engineers, you will reach them more quickly through the crowded freeways of LA than through less crowded roads elsewhere.

    Despite traffic jam, a larger number and wider variety of social communications and economic dealings can be made perfect in large, crowded cities than elsewhere. Seen in this light, traffic jam is an unfortunate result of success, not a cause of economic decline and urban decay.

    So while we can consider traffic jam as increasing costs on the areas of big cities, the costs of inaccessibility in uncrowded places are almost certainly greater.

    There is no doubt that traffic jam brings the terrible economic and environmental damage in places like Bangkok, Jakarta, and Lagos. But mobility(移动性)is far higher and traffic jam levels are far lower here in the US, even in our most crowded cities. That's why, for now, we don't see people and capital streaming out of San Francisco and Chicago, heading for other cities in California, and Illinois.

    Most people who fly on passenger planes in the United States do not lose their luggage. Even if the luggage is lost, usually it is only delayed. Most "lost" luggage is found in a few days. Airlines search for the owners of unclaimed(未认领的) bags for up to three months. But when the owners cannot be found or the bags are not claimed, they are sold to a store in the small city of Scottsboro, in the southern state of Alabama.

    About one-half of one percent of all luggage passing through US airports is unclaimed. Many of the missing bags, and what is in them, are sold at the Unclaimed Baggage Center. Seven thousand items arrive at the store every day. Tom Barnes, who was shopping at the store said, "I can go into any of the large shopping centers, like the international malls. I can walk through there for an hour and come out with three items. But I come into this store, and then I come out with my car full of stuff."

    Brenda Cantrell, who works at the store, said, "The Unclaimed Baggage Center is the only store in America that buys and resells unclaimed baggage from the airline industry. You would be surprised at all the jackets, eyeglasses, neck pillows, blankets, laptops, Kindles, iPads, and you know, all kinds of expensive electronics."

    The store says it once sold a container for flowers for $80 that was found to be worth $18,000. And it says a painting it sold for $25 was later found to be worth $25,000.

    The store buys the luggage from the airlines. It does not examine the things inside them before buying them. Only about half of the items in the bags are suitable for sale at the store.

    Some people say it is not fair to the owners of the lost passage to sell their goods. Customer Daniel Martin is not one of them, saying, "I feel the airport may try to find the people that lose the things. If they've tried and they can't get a hold of them, it's better than throwing them away or just letting them rot in a warehouse somewhere."

    One day in the gym, I asked a coach, "What's the difference between the best athletes and everyone else?" He briefly mentioned the things that you might expect: genetics, luck, talent.

    But then he added something I wasn't expecting. "At some point," he said, "it comes down to who can handle the boredom of training every day and doing the same practice over and over again."

    Most of the time people talk about getting motivated to work on their goals. As a result, I think many people get depressed when they lose focus or motivation because they think that successful people never lack motivation that they seem to be missing. But that's exactly the opposite of what this coach was saying.

    When I was an athlete, I loved going to practice the week after a big win. Who wouldn't? Your coach is happy, your teammates are excited, and you feel like you can beat anyone. As an entrepreneur, I love working when customers are rolling in and things are going well. Getting results has a way of pushing you forward.

    But what about when you're bored? What about when the work isn't easy? What about when it feels like nobody is paying attention or you're not getting the results you want? It's the ability to work when work isn't easy that makes the difference.

    If you look at the people who are consistently achieving their goals, you start to realize that it's not the events or the results that make them different. It's their commitment to the process. They fall in love with the daily practice.

    So, fall in love with boredom. Fall in love with repetition and practice. Fall in love with the process of what you do and let the results take care of themselves.

    There was an earthquake this morning. I was working in front of my computer when it hit the city. The quake started with a sudden loud noise. I thought that something heavy in a neighbor's house probably had fallen. However, the walls and the floor began to shake. I finally realized it was an earthquake.

    My son Zac, a sixteen­year­old boy, was sleeping with his door locked. Being sixteen, he can sleep through any kind of noise. "Zac!" I shouted. "Are you OK?" But nobody replied. I was a little worried. I couldn't imagine that someone was able to get such a deep sleep. The house was dancing. There were waves in the swimming pool. I was afraid the house would come down. "Zac!" I yelled, knocking on his door with an open palm (手掌). "Zac! Wake up! It's an earthquake! We need to get out!"

    My son finally emerged in his underpants. We looked around the room. I knew that we should hide under a table to stop things from falling on us and stay away from glass. Unfortunately, none of our furniture was designed for hiding under. "Should we go into the garden?" Zac asked. "No, trees could fall on us!" I said. Actually, Zac had done earthquake drills (训练) at school. He must have been told to hide under a desk and cover his head. But we had nothing to cover our heads in the house.

    Luckily, before we took any action, the windows stopped moving and the pool calmed down. Everything went back to normal soon. But both my son and I knew what we should do, because we knew if there had been a really big earthquake this morning, we couldn't have escaped from it.

Journalists are the major group of people who make their living from writing. Many young people who see themselves as future novelists choose journalism as a way of earning a living while developing their writing skills. Although writing for newspapers and writing for books require different qualities, the aspiration (志向) to be a great writer is not one to be discouraged in a would-be journalist.

Most people want their work to be recognized by others. This helps to give it value. Some people also want themselves to be recognized, so that they have status (地位) in the eyes of society. It is not a bad motive to wish to be famous, but this must never become your main reason for being a journalist. You will not be a good journalist if you care more for impressing your audience than for serving their needs.

Knowing the power of the printed or spoken word or image, some people enter journalism for the power it will give them to influence people. There is a strong belief that journalists control the mass media but the best journalists recognize their role as servants of the people. There is a difference between the desire to influence events for your own sake, and the desire to do it for other people. You should never use journalism for selfish ends, but you can use it to improve the life of other people.

Curiosity is a natural part of most people's characters and an important ingredient for any journalist. Lots of young men and women enter the profession with the desire to know more about the world without needing to specialize in limited fields of study. Most journalists tend to know a little bit about a lot of things, rather than a lot about one subject. Knowledge has many uses. It can simply help to make you a fuller and more interesting person. It can also give you power over people, especially people who do not have that particular knowledge. Always bear in mind that power can be used in a positive way to improve people's lives.
