My husband Jeff and I moved into our new home in Scottsbluff last year just before Christmas. I did not have the time or energy to carry out my traditional Christmas decorating and baking activities. What was the point, anyway? It was going to be a lonely Christmas after all.

    However, the neighborly nature of west Nebraska residents started to trickle (陆续来临) in.

    There was a knock on the door one evening. It was Jeff's new colleague, John Smith, and his wife, Phyllis. The Smiths had stopped by to welcome us to town with a loaf of homemade bread. They pointed out a package on the porch (门廊). Apparently the doorbell wasn't working in the cold snowy weather and we had missed a visit from the Browns, our across-the-street neighbors, who brought us a Christmas card and more Christmas cookies.

    Then, we received an invitation to share a Christmas Eve meal with our neighbors, Ernie and Nancy Sommer, and their guest—a 90-year-old lady, who also had no family in the immediate area with whom to spend the holiday.

    I was so grateful for these gestures of welcome, especially during the holidays.

    This year, we were again unable to be with our families for Christmas. The distance and work schedules just made things too difficult. Knowing that sense of Christmas isolation all too well, we decided to try to round up some other folks who were alone in the holidays.

    Lonely people are all around us, but most of us seldom notice them. Just take a look around you. Sometimes, the smallest kind gesture can make a world of difference.

    Scientists in Argentina have created the world's first cow with two human genes that will enable it to produce human-like milk.

    Genetic engineering was used to introduce the "mothers' milk" genes into the animal before birth, according to the National Institute of Agribusiness Technology in Buenos Aires.

    As an adult, the cloned cow "will produce milk that is similar to that of humans", which will prove "a development of great importance for the nutrition of infants(婴儿)", said the institute. "The cloned cow, named Rosita ISA, is the first in the world with two human genes that contain the proteins present in human milk," said the statement.

    In April, scientists in China published details of research showing that they had created dairy cows which produced milk containing proteins found in human breast milk. But the Argentine team said the Chinese only introduced one human gene, while their research involved two, meaning the milk will more closely resemble that of humans.

    “Our goal was to raise the nutrition value of cows' milk by adding two human genes, which do good to the immune system of infants,” said Adrian Mutto, from the National University of San Martin which worked with the institute.

    Cristina Kirchner, President of Argentina, said that the scientific institute made all Argentines proud. She also said that she had refused the "honor" of having the cow named after her. "They came to tell me that the name is Cristina, but what woman would like to have a cow named after her? It appeared to me to be more proper to call it Rosita.”

    When it's five o'clock, people leave their office. The length of the workday, for many workers, is defined by time. They leave when the clocks tell them they're done.

    These days, the time is everywhere: not just on clocks or watches, but on cellphones and computers. That may be a bad thing, particularly at work. New research shows that clock based work schedules hinder creativity.

    Clock-timers organize their day by blocks of minutes and hours. For example: a meeting from 9 a. m. to 10 a. m, research from 10 a. m to noon, etc. On the other hand, task-timers have a list of things they want to accomplish. They work down the list, each task starts when the previous task is completed. It is said that all of us employ a mix of both these types of planning.

    What, then, are the effects of thinking about time in these different ways? Does one make us more productive? Better at the tasks at hand? Happier? In experiments conducted by Tamar Avnet and Anne-Laure Sellier, they had participants organize different activities from project planning, holiday shopping, to yoga by time or to-do list to measure how they performed under "clock time" vs. " task time". They found clock timers to be more efficient(有效率的) but less happy because they felt little control over their lives. Task timers are happier and more creative, but less productive. They tend to enjoy the moment when something good is happening, and seize opportunities that come up.

    The researchers argue that task-based organizing tends to be undervalued and under-supported in the business culture. This might be a small change to the way we view work and the office, but the researchers argue that it challenges a widespread characteristic of the economy: work organized by clock time. While most people will still probably need, and be, to some extent, clock-timers, task-based timing should be used when performing a job that requires more creativity. It'll make those tasks easier, and the task-doers will be happier.

New Schedules（日程/安排）of Cathay Pacific Airways(航班)

    Ahead of the summer travel season, airlines in the United States usually compete to sell tickets and fill seats. But the airlines that operate the grounded Boeing 737 Max planes have a new problem: there are not enough seats to meet the demand.

    The revenue(收益)is right in front of them. They can see it, but they can't meet it, said Mike Trevino. He is an airline industry expert for Southwest Airlines Pilots Association, The grounding of Boeing's 737 Max came after two deadly crashes in five months. Southwest Airlines is the world's largest 737 Max operator. The company has 34 of the planes.

    American Airlines operates the second-most, with 24. These planes have been removed from use until at least August, The grounding of the planes has led Southwest to cancel 160 of its 4,200 daily flights between June 8 and August 5.

    American Airlines will cancel 115 daily flights, or 1.5 percent of its total summer flights .Southwest only flies Boeing 737s. It had estimated $ 150 million in lost revenue between February and March 31--mostly because of MAX cancellations.

    The 737Max was grounded worldwide in March following a deadly Ethiopian Airlines crash. It came five months after a Lion Air crash in Indonesia. All on board both planes died.

    Boeing is under pressure to provide additional software. Experts are examining the original software as a possible reason for the crashes.

    Boeing must prove to worldwide regulators that the plane is safe to fly. That process may take more than 90 days. Planes in the United States are usually mostly full during the months of June, July and August.

    It is every kid's worst nightmare(噩梦) and six-year-old Jaden Hayes has lived it twice. First he lost his dad when he was only at the age of four and then last month his mom died unexpectedly in her deep sleep.

    "I tried and I tried and I tried to get her awake, but... I just couldn't," said Jaden.

    No one could imagine how heartbroken Jaden was.

    But there's another side to his sadness. A side he first made public a few weeks ago when he told his aunt, Barbara DiCola, and now his guardian(监护人)after both his parents died, that he was sick and tired of seeing everyone sad all the time. And he had a plan to fix it.

    "And that was the beginning of it," said Barbara. "That's where the adventure began."

    Jaden asked his aunt Barbara to buy a bunch of little toys and bring him to downtown Savannah, Georgia near where he lives, so he could give them away to anyone who will smile to him. "I'm trying to make people smile," said Jaden.

    Jaden targets people who aren't already smiling and then turns their day around. He's gone out on four different occasions now and he is always successful. Even if sometimes he doesn't get exactly the reaction he was hoping for.

    It is just so overwhelming to some people that a six-year-old orphan would give away a toy -- expecting nothing in return -- except a smile.

    "I'm depending on it to be 33, 000," said Jaden. When asked if he thinks he can make that goal, he answered: "I think I can."
