Vitamin B could help reduce the effects of the dangerous type of air pollution, according to a new study published on Monday. In the first study of its kind, a team of international researchers looked into the damage caused by one of the pollutants that have the severest impact on health—PM2.5.

    They found that Vitamin B supplement could effectively reduce the impact of the tiny particles     （颗粒）on the human body, although they stressed that the research was in its early stages. According to the WHO, 92% of the world's people are living in places where the PM2.5 level goes beyond the recommended level. So it's urgent to find a solution to the problem.

    According to this study, published in the PNAS, 10 volunteers were initially exposed to clean air and given a placebo (安慰剂）to check their baseline responses. The group then kept on taking placebos tor tour weeks before being exposed to heavily polluted air from downtown Toronto, where an estimated 1,000 cars passed every hour. The bad air was delivered to the volunteers through an "oxygen type" face mask. The experiment was then repeated, with each volunteer taking a Vitamin B supplement daily, made up of 2.5mg of folic acid, 50mg of Vitamin B6, and l mg of Vitamin B12.

    Vitamin B6 can be found in liver, chicken, nuts and other things, and Vitamin B12 in fish, meat, eggs, milk and some cereals. The researchers found that four weeks of Vitamin B supplements — the damage of PM2.5 effects by 28-76%. The results emphasized how prevention at an individual level could be used to fight against the damage of PM2.5, the researchers said.

    Libraries are doing well in the digital times. Here are some of the most awesome examples.

    ⒈Freiburg University Library, Germany

    The original library of the Freiburg University was rebuilt in 2015 following the project of Degelo Architects. The new building has 41,000 square meters and looks like a cut diamond. Inside, there are 1,200 workspaces in four reading rooms plus 500 work areas. The library offers in the basement a system of automated checkout machines and 700,000 volumes that can be borrowed.

    ⒉Microlibrary at Taman Bima, Indonesia

    This wonderful little public library is located in a Kampung neighborhood near the Bandung airport, Indonesia. The building was designed by the Bandung office of SHAU architect studio. It has 160 square meters and is built upon a preexisting stage that was already used by the local community for events and gatherings. The Bima public library is the first of a series of similar microlibraries that are planned to be built across Indonesia.

    ⒊Public Library of Constitución, Chile

    The city in Constitución, Chile, was devastated by 8.8 degrees earthquake in 2010. The new public library, designed by Sebastian Irarrázaval, is a part of the initiative to rebuild the city. Constitución is one of the biggest clusters of wood production in Chile. This heritage is reflected in the construction of this post-disaster library. It's made almost entirely of wood, and only the firewalls are done with exposed poured concrete. The internal area of the library exceeds 350 square meters. The building was opened in 2015, five years after the earthquake.

    ⒋LiYuan Library, China

    Built in 2011 in a small village of Huairou on the outskirts（郊区）of Beijing, this beautiful nature-inspired library was designed by Li Xiaodong. The 175-square-meter building's interior is spatially diverse by using steps and small level changes to create distinct places. The wooden sticks temper the bright light and spread it evenly throughout the space to give a perfect reading environment. The library closes at dusk because there is no electricity in it.

    Gorillas(大猩猩) are on the edge of extinction. They are calling on YOU to donate your phone today!

    You can now help save gorillas in Africa simply by donating your mobile phone! Coltan is a metallic ore(金属矿石) that is mined both in and out of Africa and can be found within many electronic devices such as mobile phones. The mining of coltan within the Congo River Basin is contributing to forest loss there, and is speeding up the loss of mountain gorillas at a shockingly fast rate. While efforts are being made to deal with this issue, the mining of coltan within gorilla habitat continues. It is very difficult to know which phones contain coltan mined from Africa; however, every phone can help save gorillas when donated to They're Calling on You.

    By donating your phone through the They're Calling You mobile phone recycling program you are:

    Preventing your phone from going to the landfill.

    Helping Melbourne Zoo raise money to support the Jane Good all Institutes monkey conservation work in Africa through the sale of refurbished(翻新)phones.

    Lessening the demand for coltan mining.

    To support the They're Calling You mobile phone recycling program you can:

    ⒈Visit Melbourne Zoo to collect a postage paid recycling bag, and post your mobile phone to the Aussie Recycling Program. Your phone will be resold to poor community groups.

    ⒉Register your support simply by emailing the registration form to zvfoundation@zoo.org.au or fax it to (03)9285-9377.

    Schools can get involved too! Please contact Kate McCabe at Melbourne Zoo by email or phone(03)9285-9471 Discuss adding this program to your course while inspiring students to take action for wildlife.

    The most important thing to keep in mind when going into high school is to be yourself. Besides, I don't know what your middle school was like, but high school teachers will not care about things such as how much homework you already have in one night. It's best to just learn to deal with things and manage your time wisely so you can achieve everything you need to.

    Frank, Aged 21

    I think almost every kid feels both nervous and excited before their first day. You will probably love it. I know I did. You should join some sports or activities that will make your high school experience more enjoyable. Good luck!

    Eddie, Aged 20

    When I started high school I was really nervous too, especially since I had been homeschooled （自主学习，在家教育）all through middle school and didn't really know anyone. I suppose the best advice would be to just relax. The first couple of days can be a little bit hard, but things will become easier before you know it.

    David, Aged 19

    I'm not going to lie. The first day is kind of frightening(令人恐惧的). But you'll get used to it. Don't be afraid of anyone; upperclassmen（高年级学生） will pick on（招惹） you more if you let them know you're afraid. Just take it easy. Making some friends and staying with them will greatly help you get used to high school quickly. After the first week it's really not bad at all. Don't worry.

    HANGZHOU-Chinese internet giant Alibaba on Tuesday opened a hotel loaded with artificial intelligence (AI) and robots, automating a series of procedures like check-in, lights control and room service.

    FlyZoo Hotel, opened in Hangzhou, capital of East China's Zhejiang province, where Alibaba is headquartered, is known as the company's first "future hotel". Customers can check into the hotel by simply scanning their faces. The facial recognition system installed in the hotel also enables customers to use their faces as key cards to open doors and access another hotel service. Users can also control the lights, televisions and curtains in the room via Alibaba's voice-activated digital assistant, while robots are deployed to serve dishes, cocktails and coffee. Hotel bookings and check-out can also be done with a few clicks on mobile through an app. The Al-based solution can help customers save time and relieve hotel employees from repetitive work," said Wang Qun, CEO of FlyZoo Hotel. The hotel is the latest example of Chinese tech companies1 attempt into traditional industries such as the hotel industry.

    E-commerce giant JD.com announced in October its strategy to put smart home and electronic devices sold on its platform into hotels, in an effort to improve online sales.

    In July, Baidu teamed up with Intercontinental Hotels Group in Beijing to allow guests to use its voice-controlled assistant to adjust room temperature and order room service at ease.

    Before that, social media giant Tencent introduced QQ family, a similar tech solution for hotel operators, in the southern city of Zhuhai last year.

    "We want to install a 'smart brain' for hotels, " said Wang, "In the future, we will continue to make hotels smarter and more automated, as well as create more personalized experiences for consumers."
