China is starting to blacklist poorly-behaved tourists as it seeks to rescue the image of its citizens as holidaymakers.

    According to a regulation by the China National Tourism Administration (NTA) that entered effect this week, tourists will be blacklisted for offences including acting antisocially on public transport, damaging private or public property, disrespecting local customs, damaging historical exhibits on purpose or engaging in gambling or pornographic activities. Records will be kept in a two-tired system: provincial-level tourism authorities are responsible for cases under their jurisdiction（管辖区域）while the NTA will be in charge of a nationwide register. People will be .blacklisted for two years after they offend, according to the regulation.            

    The NTA said tourism authorities will inform blacklisted tourists and “propose correction measures in order to mitigate the negative impact”. It also said that tourism authorities reserve the right to report such violations to public security, customs and transport authorities as well as the central bank's individual credit department.

    The regulation comes amid (在……之中) growing concern about the ill manners of Chinese tourists both at home and abroad. In 2013, a Chinese tourist wrote his name on a relief carving in Luxor, Egypt. In December, a Chinese passenger threw a cup of hot instant noodles at a flight attendant on an international flight. Chinese tourists have been fined or put into prison for carrying prohibited items or purchasing wild animal products.

    Six million people visit Grand Canyon in the US every year. For the purpose of helping project Grand Canyon for your fellow visitors and future generations, please follow the guidelines below.

    Camping

    To protect the park, camping is allowed only within permitted campgrounds. Permits are required for overnight camping at the North Rim. Advance booking can be received by mail. Please write: Information Center, P.O. Box 129, Grand Canyon, AZ 86023.

    Fires

    Because of the extreme fire danger, campfires are not allowed except at Mather and Desert View campgrounds. Collection of firewood is not allowed either.

    Hiking（远足）

    Please stay on permitted paths. Otherwise you may destroy desert plants. Pack out what you pack in, so you leave no signs of your visit. It is important to keep in mind that you are in a national park where wildlife exists.

    Weather

    The weather at Grand Canyon can change very quickly. With so much rock, lightning(闪电) causes a particular danger during sudden summer storms These storms also frequently bring floods inside valleys, a danger to hikers. Watch the skies and check daily weather reports.

    Wildlife

    Do not feed park wildlife. There have been a few cases at Grand Canyon National Park where deer(鹿) were purposely shot because there are plastic bags that left them sick and weak. Hungry deer car be danger and have kicked and bitten visitors at Grand Canyon. Some other animals will also beg and bite. For your own safety and the well-being of the animals, please do not feed wildlife, no matter how gentle they may appear.

    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.

Four things that you can't miss in Macao

    Go Bungee Jumping at the Macao Tower

The Macao Tower, 338 meters tall, is the world's 10th highest tower, with kinds of activities, such as eating and entertainment. One of the activities is the bungee jump. The Macao Tower Bungee Jump is 233 meters high, making it a Guinness World Record as the highest commercial bungee jump in the world. Raise your arms and off you go! If you are not daring enough to jump that height, you can try the sky walk on the 57th floor—it's still amazing. Take this chance and tick off this item on your list.

Enjoy a traditional Portuguese dinner

    Macao was once colonized (殖民) by Portugal before 1999. As a result, Portuguese culture has deeply affected Macao.

    Many Portuguese settled and opened Portuguese restaurants here, but it is more adaptable to Chinese people.

    Visit a museum

    Macao, as a little city with only an area of 30.5 square kilometers, has 23 eye-catching museums. Due to its special history, both eastern and western historical relics can be found. Many of them are preserved for cultural relics, tourist spots or museums, such as the Grand Prix Museum, Maritime Museum and Wine Museum.

Go into an entertainment place

    Well known as the “Las Vegas of the Orient”, Macao has 33 entertainment places. You can find different themed entertainment places with their hotels and attractions around every corner of Macao, especially on Taipa Island. Among all, The Venetian is the most popular. With a huge shopping mall and Vegas-style design, it is a must-go place for both tourists and locals to shop and enjoy free time. So when you come to Macao, just walk around and you will still be amazed.

    "You can use me as a last resort(选择), and if nobody else volunteers, then I will do it." This was an actual reply from a parent after I put out a request for volunteers for my kids' lacrosse(长曲棍球) club.

    I guess that there's probably some demanding work schedule, or social anxiety around stepping up to help for an unknown sport. She may just need a little persuading. So I try again and tug at the heartstrings. I mention the single parent with four kids running the show and I talk about the dad coaching a team that his kids aren't even on … At this point the unwilling parent speaks up, "Alright. Yes, I'll do it."

    I'm secretly relieved because I know there's real power in sharing volunteer responsibilities among many. The unwilling parent organizes the meal schedule, sends out emails, and collects money for end-of-season gifts. Somewhere along the way, the same parent ends up becoming an invaluable member of the team. The coach is able to focus on the kids while the other parents are relieved to be off the hook for another season. Handing out sliced oranges to bloodthirsty kids can be as exciting as watching your own kid score a goal.

    Still, most of us volunteers breathe a sigh of relief when the season comes to a close. That relief is coupled with a deep understanding of why the same people keep coming back for more: Connecting to the community(社区) as you freely give your time, money, skills, or services provides a real joy. Volunteering just feels so good.

    In that sense, I'm pretty sure volunteering is more of a selfish act than I'd freely like to admit. However, if others benefit in the process, and I get some reward too, does it really matter where my motivation lies?

    Researchers in Australia have discovered an effective new method to capture the atmospheric carbon dioxide that is damaging our planet and transform it into something solid, making it much easier to store.

    Carbon capture isn't new, but previous methods call for the gas to be compressed into liquid and then injected underground. Widespread usage of that technology has been locked by economic and environmental concerns due to possible leaks. Instead, in a study published in Nature Communications, the group details their sustainable and cost-effective plan for transforming CO₂ into coal.

    This new process involves a liquid metal catalyst(催化剂)that is efficient in conducting electricity. CO₂ gas is dissolved in a container with some liquid. Once electricity charge is introduced, the CO₂ begins to turn into solid pieces of carbon, which can be collected and stored.

    What makes this particularly unique is that the entire process can occur at room temperature. Previous experiments have only shown a gas to solid conversion at extremely high temperature, which made it impossible on a large scale. Now, the researchers are hoping that their work will be used to create even further when it comes to carbon storage.

    In an interesting side benefit, the solid carbon also works as an electrode(焊条), which opens up a world of possibilities. "A side benefit of the process is that the carbon can hold electrical charge, becoming a super battery, so it could potentially be used as a part in future vehicles," explains Dr. Dorna Estrafilzadeh, a researcher. "The process also produces fuel as a by-product, which could also have industrial applications."
