    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.

    Each year,half a million people die from brain aneurysms(动脉瘤)—when a blood vessel bursts in the brain.An aneurysm is a bulge in a blood vessel that can burst.If that happens in the brain,it can be deadly.For survivors,physical disabilities are often severe.They may include memory problems,loss of balance,trouble speaking and even blindness.But new technologies are increasing survival rates and reducing disabilities.

    Beaumont Bacon is a survivor who makes light of her experience because she is a comedian.She uses humor to make others laugh.Now she's working on a new show.Michael Alexander is her doctor.He operated on Beaumont Bacon after her attack.“She had bleeding in the frontal area of her brain,so right above the eyes.The part that was in the brain was about maybe the size of an egg.So,that's a fairly large bleed.”

    Ms.Bacon had a better chance at survival than most people because of Dr.Alexander.He directs the Neurovascular Center in Los Angeles.The center offers new technologies that include placing a catheter(导管) into an aneurysm,then threading wires to promote blood clots(血栓).This technique reduces the chances of another burst blood vessel.“You don't have to open up the skull or open up the brain to do surgery.It's all done from inside the blood vessels.So it reduces the amount of blood loss,and the recovery is much faster.”

    For Beaumont Bacon's recovery,the hospital worked to prevent problems commonly found in patients with a burst aneurysm.The problems include brain swelling that can shut down blood vessels.She spent a month in a coma(昏迷)—unable to communicate with doctors,friends and loved ones.But with a year of treatment,she recovered.Now,she is making people laugh.

    I look back sometimes at the person I was before I rediscovered my old professor. I want to talk to that person. I want to tell him what to look out for, what mistakes to avoid. I want to tell him to be more open, to ignore the temptation of advertised values, to pay attention when your loved ones are speaking, as if it were the last time you might hear them.

    Mostly I want to tell that person to get on an airplane and visit a gentle old man in West Newton, Massachusetts, sooner rather than later, before that old man gets sick and loses his ability to dance.

    I know I cannot do this. None of us can undo what we've done, or relive a life already recorded. But if Professor Morrie Schwartz taught me anything at all, it was this: there is no such thing as “too late” in life. He was changing until the day he said good-bye.

    Not long after Morrie's death, I reached my brother in Spain. We had a long talk. I told him I respected his distance, and that all I wanted was to be in touch—in the present, not just the past—to hold him in my life as much as he could let me.

    “You're my only brother,” I said. “I don't want to lose you. I love you.”

    I had never said such a thing to him before. A few days later, I received a message on my fax machine. It was typed in the sprawling, poorly punctuated, all-cap-letters fashion that always characterized my brother's words.

    “HI I'VE JOINED THE NINETIES!” it began. He wrote a few little stories, what he'd been doing that week, a couple of jokes. At the end, he signed off this way:

I HAVE HEARTBURN AND DIAHREA(腹泻) AT THE MOMENT—LIFE'S A BITCH. CHAT LATER?

[signed] SORE TUSH.

I laughed until there were tears in my eyes.

    This book was largely Morrie's idea. He called it our “final thesis.” Like the best of work projects, it brought us closer together, and Morrie was delighted when several publishers expressed interest, even though he died before meeting any of them. The advance money helped pay Morrie's enormous medical bills, and for that we were both grateful.

    The title, by the way, we came up with one day in Morrie's office. He liked naming things. He had several ideas. But when I said, “How about Tuesdays with Morrie?” he smiled in an almost blushing way, and I knew that was it.

    After Morrie died, I went through boxes of old college material. And I discovered a final paper I had written for one of his classes. It was twenty years old now. On the front page were my penciled comments scribbled to Morrie, and beneath them were his comments scribbled back.

    Mine began, “Dear Coach . . .”

    His began, “Dear Player . . .”

    For some reason, each time I read that, I miss him more.

    Have you ever really had a teacher? One who saw you as a raw but precious thing, a jewel that, with wisdom, could be polished to a proud shine? If you are lucky enough to find your way to such teachers, you will always find your way back. Sometimes it is only in your head. Sometimes it is right alongside their beds.

    The last class of my old professor's life took place once a week, in his home, by a window in his study where he could watch a small hibiscus(木槿) plant shed its pink flowers. The class met on Tuesdays. No books were required. The subject was the meaning of life. It was taught from experience.

    The teaching goes on.

    There's a trend that more city people decide that they want to grow crops and raise some live-stock (家禽). After all, there are few things more satisfying than biting into a bunch of tender, red carrots you grow yourself, or a fresh egg from the backyard.

    Most gardeners understand that the soil in big cities is often polluted with lead and know to get their soil tested. But most are pretty clueless about how to prevent other types of pollutants, like heavy metals and asbestos(石棉)from getting into their vegetables.

    Part of the problem is that “there might be pollutants that gardeners can't test for,” says Brent Kim, a program officer. Most soil tests look for lead, cadrniunt(镉)and arsenic(砷). But they don't test things like chemicals left behind by cars, which might have escaped into the soil.

    So if you're thinking of staring an urban garden, Kim says, once you've found a plot of land, you should learn what's now an empty plot or a backyard might once have been a parking lot, a gas station or a chemical ground. “Knowing its past will give you some idea about what might be in that soil,” he says.

    “People tend to think raised beds are going to solve their pollution problem,” Kim says. But polluted soil could easily kicked onto your plants, especially if the beds are low to the ground.

    “Another consideration is that you have to be careful about the materials that you're using to build a raised bed,” Kim says. Recycling wood from an old construction site might seem like a good, eco-friendly idea. But that wood could be treated with chemicals you don't want touching your fruits and veggies, Kim says. And it's always a good idea to use gloves while gardening, and wash all your produce thoroughly.

    “I see these urban growing spaces as these oases(绿洲)in the middle of these urban environments,” Kim says. “They bring communities together, and they help people save money on fresh produce. Urban growing spaces are amazing. Let's keep doing this, but let's do it safely.”

    We're often reminded of the importance of preserving the planet as we see it for future generations—and children at St Oswald's Primary School in Chester certainly agree.

    Nine-year-old Isobel Kelleher from the school's Hummingbirds class thinks adults need to take note. “Sometimes they can be busy and I don't think they think they can make a difference,but if everyone does a little bit it all adds up,” she tells HuffPost UK.“ We started looking at plastic pollution in our oceans and the things like plastic bags and broken down pieces of plastic that are polluting them.” she says.“ Fish can eat the plastic and they can die,or we might even eat the fish ourselves.”

    Mr Timms,Isobel's teacher,has been spearheading a new project at the school which lets children loose creatively to raise awareness of the need to be more environmentally friendly. The entire Hummingbirds class,which is made up of 9 and 10-year-old pupils,has been busy writing poems and creating online video adverts to warn adults about the serious situation of our oceans and wildlife.

    Mr Timms thinks children have an important role to play in teaching us how to take care of the things around us. We sometimes overlook how much we can really learn from children.” he says.“ It has been really hard to believe having parents come in saying that their children have been asking them to stop using plastic,and to recycle more,and even stopping them using plastic straws.”

    Mr Timms is proud of his Hummingbirds class.“ The message that they would like to send to the world is simple stopping this isn't someone else's job,and it won't be OK if we just leave it.”

    BOXTEL, Netherlands — chickens roam the orchards, cows chew the cud and pigs roll in the mud on a warm day on a Dutch farm ——but the pastoral (乡村)scene is not as traditional as it seems.

    The farm is owned and run by a cooperative of hundreds of local consumers and aims to change habits in a low-lying country engaged in an existential fight against climate change. Nearly 200 families decide what the farm will produce — and they will eventually eat — and employ a farmer to tend to the animals for meat and eggs and grow the dozen kinds of fruits and vegetables.

    "The main aim of the members is to eat natural products, produced near to where they live, in a more sustainable (可持续的)way," said Douwe Korting, co-leader of the Boxtel Cooperative, in the southern Netherlands. People are really starting to see that a change toward a different way of eating is essential," he added.

    It costs 2,000 euros ($2,200) to join the collective (集体的)farm, which is 10 minutes by bicycle from the town, and then a weekly fee of around 10 euros per person.

    In return, members receive the food they want and stress the importance of knowing what they eat is local and seasonal.

    Known as Herenboderderij, or People's Farming, the guiding principle is that everything centers on the needs and riches of nature, even while using new technologies, " said its founder Geert van der Veer. Soon the poultry (家禽) will be joined by a robot that can sense when the fruit is ripe, as well as a drone that will survey the fields to support and reduce the needs for manpower.
