There were smiling children all the way. Clearly they knew at what time the train passed their homes and they made it their business to stand along the railway, wave to complete strangers and cheer them up as they rushed towards Penang. Often whole families stood outside their homes and waved and smiled as if those on the trains were their favorite relatives. This is the simple village people of Malaysia. I was moved.

    I had always traveled to Malaysia by plane or car, so this was the first time I was on a train. I did not particularly relish the long train journey and had brought along a dozen magazines to read and reread. I looked about the train. There was not one familiar face. I sighed and sat down to read my Economics.

    It was not long before the train was across the Causeway and in Malaysia. Johore Baru was just another city like Singapore, so I was tired of looking at the crowds of people as they hurried past. As we went beyond the city, I watched the straight rows of rubber trees and miles and miles of green. Then the first village came into sight. Immediately I came alive; I decided to wave back.

    From then on my journey became interesting. I threw my magazines into the waste basket and decided to join in Malaysian life. Then everything came alive. The mountains seemed to speak to me. Even the trees were smiling. I stared at everything as if I was looking at it for the first time.

    The day passed fast and I even forgot to have my lunch until I felt hungry. I looked at my watch and was surprised that it was 3:00 pm. Soon the train pulled up at Butterworth. I looked at the people all around me. They all looked beautiful. When my uncle arrived with a smile, I threw my arms around him to give him a warm hug (拥抱). I had never done this before. He seemed surprised and then his weather-beaten face warmed up with a huge smile. We walked arm in arm to his car.

    I looked forward to the return journey.

    Today, I had the good fortune to join the students from East Silver Spring Elementary School in Maryland as they walked and biked to school in celebration of International Walk to School Day. I want to thank Principal Morrow and the entire ESS community for welcoming me so enthusiastically.

    Walk to School Day is a great opportunity for me to spend time with parents, kids, and teachers and to present our Safe Routes to School program and the First Lady Michelle Obama's Let's Move initiative（倡议）.

    As a father, grandfather and former schoolteacher, I know how important it is that we provide students with safe choice to get to school while promoting exercise and healthy lifestyles. That's why I've embraced the Safe Routes to School program so wholeheartedly since I became Secretary of Transportation.

    You know, we're looking at an increasingly sedentary（久坐的）generation of children. One out of every three kids in America is now overweight. And I admire the First Lady's effort to end this within a generation. Safe Routes to School is a natural partner for Let's Move. For more than 10 years, Safe Routes to School has been making it easier for students to walk and bike from home to school. And ESS, where I walked today, is one of the earliest schools to participate.

    We know this program has been enormously effective because of the steady increase in the number of kids walking or biking to school. And as we made our way down the street this morning I was reminded yet again of this program's extraordinary work.

    Look, walking and biking to school is good for students' health. It's good for the environment. And it's good for the entire community's quality of life.

Everybody wins when kids take Safe Routes to School.

    Toronto is reminding citizens this month what exactly can and can't go into the blue bins an you may be surprised at what can't be recycled. As it turns out the takeout coffee cups you've been throwing into the recycling actually have to go in the garbage.

    The city's “recycle right” web explains that food left after a meal, woven (编织的) cloth, old VHS tapes and other things have been turning up in blue bins, where they don't belong.

    According to the city, about 45,000 tunes of garbage was mistakenly put into recycling bins last year alone.

    Among those things are the takeout coffee and tea cups we get while were on the go. The city says that because those paper cups are lined with plastic or wax they can't be recycled. The black plastic coffee lids (盖子) also can't go in the blue bin, although non-black plastic lids can be recycled.

    Emily Alfred, senior campaigner with the Toronto Environmental Alliance, said, “Millions of cups are used in Toronto every year and people are taking these out and putting them in the wrong bin.”

    When paper coffee cups are thrown in with the recycling. Alfred said, they produce a harmful effect on the system.

    “They can't separate the plastic and paper in a typical paper recycling center,” Alfred said, “so it just causes pollution of the recycling process, and it causes lower-quality paper if it does get recycled.”

    “New regulations passed last month call for changes to be rolled out over the next few years regarding what products companies can sell,” Alfred said. Her organization will be pushing for more producer responsibility laws, which call on companies that design and make products to take on the responsibility of recycling them.

    For now, consumers can consider carrying their own reusable coffee cups while they are on the go, ask for a ceramic mug (陶瓷杯) if they plan to consume their drink in the cafe, and support their local government officials if they have put efforts into changing recycling or producer responsibility laws.

    Alfred said, “I think people can change their habits easily if they understand what to do.”

Babies made from three people approved in UK

    Babies made from two women and one man have been approved by the UK's fertility regulator. The historic and controversial move is to prevent children from being born with deadly genetic diseases.

    Doctors in Newcastle—who developed the advanced form of In Vitro Fertilization or IVF (人工授精)—are expected to be the first to offer the procedure and have already appealed for donor eggs. The first such child could be born, at the earliest, by the end of 2017.

    Some families have lost multiple children to incurable mitochondrial (线粒体的) diseases, which can leave people with insufficient energy to keep their heart beating.

    The diseases are passed down from only the mother, so a technique using a donor egg as well as the mother's egg and father's sperm has been developed.

    The resulting child has a tiny amount of their DNA from the donor, but the procedure is legal and reviews say it is ethical (伦理的) and scientifically ready.

    "It is a decision of historic importance," said Sally Cheshire, chairwoman of the Human Fertilisation and Embryology Authority (HFEA). "I'm sure patients will be really pleased by what we've decided today."

    But some scientists have questioned the ethics of the technique, saying it could open the door to genetically-modified (转基因) 'designer' babies.

    The HFEA must approve every clinic and every patient before the procedure can take place. Three-person babies have been allowed only in cases where the risk of a child developing mitochondrial disease is very high.

    Prof Mary Herbert, from the Newcastle Fertility Centre, said, "It is enormously pleasing that our many years of research in this area can finally be applied to help families affected by these devastating diseases".

    "Now that we are moving forward towards clinical treatments, we will also need donors to donate eggs for use in treatment to prevent affected women transmitting disease to their children."

    Prof Sir Doug Turnbull, the director of the Welcome Centre for Mitochondrial Research at Newcastle University, said, "We are delighted by today's decision. We will also provide long-term follow up of any children born."

    NHS England has agreed to fund the treatment costs of the first trial of three-person IVF for those women who meet the HFEA criteria, as long as they agree to long-term follow up of their children after they are born.

    One night in 1966, Michael Chapman rushed into a folk-music club in Cornwall, England to get out of the rain, and soon found himself onstage playing the guitar.

    "They offered me a job to play for the rest of the summer. And I've been playing ever since," Chapman says. "I've told that story so many times, but it's absolutely true. If it hadn't been raining that night, I wouldn't be talking to you."

    The British guitar player has spent the 50 years since then on the road. He released some praised albums in the 1970s, but his health went downhill in the 80s and 90s. Like a lot of British artists in the 1960s, Chapman taught himself to play the guitar by listening to American jazz and blues records.

    Chapman actually taught photography, but quit when he was 26 to play music full time. When he was starting out, he was often compared to other British acoustic (原声的) guitar heroes of the time, like John Martyn and Bert Jansch.

    "The fascinating thing about Michael Chapman is that he doesn't fit in with those guys of his generation," says Andrew Male, a music journalist. "He's always- been an outsider. He never moved to London."

    And while he never became part of the London music scene, Chapman was noticed by those musicians. "The 70s caught up with him in the 80s," Male says. "He had a huge heart attack at the end of the 80s that nearly finished him off. When he made his way back into the world in the early 90s, people had forgotten about him."

    But not everyone. A younger generation of musicians in America, including Thurston Moore of Sonic Youth and a younger singer and guitarist named Steve Gumi, recently rediscovered Chapman.

    "We wanted to capture Michael's voice and character where he is now. You know, it's a little road-weary, but he still has it," Gunn says. "For me, it was really important to get that right," "He's the right old musician for present times," Male says. "I think the music he makes seems quite in tune with where we're at."

    I always feel sorry for world leaders busy dealing with fights between nations. When my three children were young, most days it was hard to keep my house from becoming a battlefield.

    It got worse as they grew older. Three years ago, Zack, then 16, couldn't make it through a day without making his sisters, Alex 11 and Taryn 9, angry.

    My husband and I tried to be understanding the boy at such an age. We reasoned, punished, and left heartfelt notes on his bed about how he was hurting our family. His answer was" I say it because it's true."

    I even tried telling the girls to fight back. Bad idea. Now I had three children at war. Whatever I said to them, they paid no attention. When there was no way out, I told everything to my sister, Mary, in an e-mail. She replied, "Don't e-mail me. E-mail him."

    Our son was online every day, mailing and talking with his friends. Maybe he would actually hear me this way. I didn't say anything different, but e-mail just took the tension away. There'd be no shouting or door banging. Zack wouldn't feel under attack.

    Zack didn't reply for days. When he finally did, his entire message was four small words. I smiled when I read them: "You're right. I'm sorry."

    The children still fought, of course, but Zack changed. Best of all, I now have a better way to talk with not one but three of them. I like it that they don't tune me out as much as they used to. They like not having to listen to me shouting to them. Or as Alex says, "You're so much nicer online."

    All I know is that the house is quiet. But we're talking.
