Secrets of Web Travel Sites

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

1 They who's on a Mac and who's on a PCand who's going to spend more.

Last year, US travel research companyOrbitz tracked people's online activities to test out whether Mac users spendmore on travel than PC users. On average, Mac users lay out US$20-30 more pernight on hotels and go for more stars. according to the Wall Street Journal. Asa result, online• travel sites show these users more expensive travel optionsfirst. To avoid inadvertently paying more, sort results by price.

 Their software doesn't always hook up to thehotel's system.

A guaranteed reservation is almostimpossible to come by anywhere — but the risk of your flight or hotel beingoverbooked increases with third-party providers. The middle-man's softwareisn't immune to system errors, so always call the hotel or airline to make sureyour booking was processed.

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

Ever notice how travel sites recommend ahotel, a rental car, and tour package all in one click? These deals usuallyfeature travel that no one wants, like flights with multiple layovers.

Check the fine print.

 You could miss out on loyalty points.

Third-party providers can get betweenyou and frequent flyer miles or points. Many hotel loyalty programmes don'trecognise external sites, others award only minimum points and exclude specialoffers, like double points on hotel stays.

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

An online travel agency can't provideassistance the same way an agent can if a flight is cancelled or a room issubstandard. Basically, when you arrive at the airport or hotel, you're justanother client who booked at the lowest rate.

    Health experts are calling for action to increase cancer care and control in the developing world. A medical research paper says cancer was once thought of as a problem mostly in the developed world. But now cancer is a leading cause of death and disability in poor countries as well. Experts from Harvard University and other organizations urge the international community to fight cancer actively, saying it should be fought in the way HIV/AIDS has been fought in Africa.

    Cancer kills more than 7.5 million people a year worldwide. Almost two thirds are in low-income and middle-income countries.

They discover cancer kills more people in developing countries than AIDS, tuberculosis and malaria combined. But the world spends only 5% of its cancer resources in those countries.

    Felicia Knaul from Harvard Medical School was one of the writers of the paper. She was in Mexico when she was found to have breast cancer. She received treatment there and her experience showed her the sharp difference between the rich and the poor in treating breast cancer.

    Felicia Knaul says, “And we are seeing how this is attacking young women. It's the number two cause of death in Mexico of women thirty to fifty-four. All over the developing world, it's the number one cancer-related death among young women. I think we have to again say that there is much more we could do about it than we are doing about it. ”

    Professor Knaul met community health workers during her work in developing countries. They were an important part of efforts to reduce deaths from the cancer. They were able to persuade people to get tested to prevent the illness. The experts say cancer care does not have to be costly. For example, patients can be treated with lower-cost drugs.

    If you like texting and are trying to lose weight, a new study found that using texting to track(追踪) diet and exercise habits may help you lose weight.

    Previous research has shown that keeping food and exercise diaries improves the likelihood of success when you are trying to lose weight. Using a computer or a pen and paper to record information, however, can be a burden and cause some people to give up.

    Duke University researchers said using text messages to track eating and exercise habits can save time, and increase the chances that people will stick with their weight-loss rules.

    The study included 26 obese women with an average age of 38. The women used daily texting as part of their weight-loss program. The text messages focused on tracking personalized goals, such as avoiding sugary drinks or walking 10,000 steps a day. Messages also provided brief feedback (回复) and tips.

    Every morning, the women received a text from an automated(自动的)system that said, "Please text yesterday's personal information of steps you walked and how many sugary drinks you had." Based on the women's responses to the text message, the system sent another text with personalized feedback and tips.

    After six months, the women who used daily texting lost an average of nearly 3 pounds, while another group of women who used traditional methods to keep food and exercise diaries gained an average of 2.5 pounds, according to the study, which was published in the Journal of Medical Internet Research.

    "Text messaging has become popular and may be an effective method to simplify tracking of diet and exercise behavior," Dori Steinberg, who was responsible for this research, said.

    Steinberg said, "Text messaging offers several advantages compared to other self-monitoring methods. Unlike web-based diet and exercise diaries, data in a text message can be entered quickly on nearly all cellphone platforms so it is very convenient to receive feedback. Besides, because of the limited number of words used in text messages, it saves time."

    Hannah Levine decided she wanted to give hugs to all of the children and families in need at local hospitals.

    Because she couldn't give them hugs one by one, Levine, then a sixth-grader, decided she would use her talents(才能) to do the next best thing. She began to knit(编织) hats, scarves, and blankets for families staying at the Ronald McDonald House at Stanford. Her creations also went to Bundle of Joy, a program that provides newborn baby items for families in need, and to Knitting Pals by the Bay, a local organization that provides hand-knitted caps to cancer patients.

    "I love to knit, and I thought it would be a great idea to make all these handmade items for kids and adults who need them. It would be like a hug for them." Levine explained.

    Levine started the project about a year ago. "I think it's just really fun to do, and it keeps me busy." said Levine, now 13.

    Once she got started, Levine realized that her project could be much bigger than the goods she was able to produce with just her own hands. So she sent emails to her school and communities, asking for knitted donations(捐赠物) to the project she named "Hannah's Warm Hugs". She also posted advertisements at Starbucks and other locations in her area. The warm goods began to pour in.

    "It was amazing; more strangers than people she knew started dropping donations at our door." said Levine's mother, Laura Levine. "We ended up with this huge box of items she was donating."

    The knitted items numbered in the hundreds. Levine made her first round of donations around Hanukkah (an eight-day Jewish holiday in November or December) and later received thank-you letters from the organizations. Levine is still knitting, and she said the project will continue.

    "It has turned into a bigger thing than she had thought." her mom said. "It made her feel pretty good; it made us feel pretty good.”

    Scientists have connected the "fat gene" with the "happy gene". They believed there could be genetic evidence which explains why fat people are often happier than their skinny friends. The breakthrough could be an explanation for why fat characters, such as The Laughing Policeman and Father Christmas are often described as joyful and kind.

    FTO is the major genetic contributor to being fat. But it is also connected with an eight percent reduction in the risk of depression. Researchers at McMaster University in Canada had been studying whether there was a connection between being fat and being depressed. They found the opposite was true.

    They studied 17, 200 DNA from participants in 21 countries. Results showed people with FTO gene—the fat gene—showed less signs of depression. This finding was supported by three additional international studies.

    Professor David Meyre said, "We set out from the belief that being depressed and being fat both deal with brain activity. We thought that fat genes may be related to depression. However, we have discovered a molecule (分子) contributing to depression. It is the first evidence that an FTO fat gene is connected with protection against depression.

    In a recent interview, actress Lisa Riley said she was more than comfortable with her size. She said she is a "big, really happy" girl who is lucky enough to be confident in her own skin, and added, "Many people want to be thinner. Not me. I love being different and it drives me mad that people don't believe I'm happy with what I am."
