Your house may have an effect on your figure. Experts say the way you design your home could play a role in whether you pack on the pounds or keep them off. you can make your environment work for you instead of against you. Here are some ways to turn your home into part of your diet plan.

      Open the curtains and turn up the lights. Dark environments are more likely to encourage overeating, for people are often less self-conscious(难为情) when they're in poorly lit places – and so more likely to eat lots of food. If your home doesn't have enough window light, get more lamps and flood the place with brightness.

      Mind the colors. Research suggests warm colors fuel our appetites. In one study, people who ate meals in a blue room consumed 33 percent less than those in a yellow or red room. Warm colors like yellow make food appear more appetizing, while cold colors make us less hungry. So when it's time to repaint, go blue.

Don't forget the clock – or the radio. People who eat slowly tend to consume about 70 fewer calories(卡路里) per meal than those who rush through their meals. Begin keeping track of the time, and try to make dinner last at 30 minutes. And while you're at it, actually sit down to eat. If you need some help slowing down, turning on relaxing music. It makes you less likely to rush through a meal.

Downsize the dishes. Big serving bowls and plants can easily makes us fat. We eat about 22 percent more when using a 12-inch plate instead of a 10-inch plate. When we choose a large spoon over a smaller one, total intake(摄入) jumps by 14 percent. And we'll pour about 30 percent more liquid into a short, wide glass than a tall, skinny glass.

    “I like photography because it captures amazing things that you might not see again,” Timmy Walsh says. He takes pictures of flowers, sunsets and road signs. But those photos don't usually end up in a scrapbook(剪贴簿) or on his bedroom walls.

    When Timmy was five, he found out that his aunt Bev had lung cancer. He wanted to do something to help her. His first idea was to sell his photos from a lemonade--type stand in front of his house in Pennsylvania. “My mom said it wouldn't work because we were not on a busy street,” Timmy explains.

    His next idea was to have an art show. Timmy decorated his home with candles, flowers, and white lights. Then he arranged his photos. Timmy's mom, Sheila, remembers: “Our dining-room table was filled, the living room—everything was filled with photos.” Friends, family, and Timmy's teachers came to the show. He raised more than $300 for cancer research that night. Aunt Bev was “very happy and excited,” he says.

    After a local newspaper wrote a story about Timmy's photos, a volunteer offered to help him set up a website. As people learned about his cause, called Camera for a Cure, Timmy began receiving invitations to sell his pictures at art galleries and fund-raisers. Since then, his work has appeared in more than 20 shows.

    When Timmy is at a show, he greets each customer and talks about what he was thinking when he took his photos. And he always shares facts about lung cancer. Sometimes donations and sales are slow, but that doesn't bother him. “It doesn't matter how much money we made because we just raised awareness,” he says. Timmy knows that finding a cure for lung cancer will take time and effort. So Timmy will keep doing his part by shooting and selling photos of the things he sees.

    If a diver surfaces too quickly, he may suffer the bends. Nitrogen (氮) dissolved (溶解) in his blood is suddenly liberated by the reduction of pressure. The consequence, if the bubbles (气泡) accumulate in a joint, is sharp pain and a bent body—thus the name. If the bubbles form in his lungs or his brain, the consequence can be death.

    Other air-breathing animals also suffer this decompression (减压) sickness if they surface too fast: whales, for example. And so, long ago, did ichthyosaurs. That these ancient sea animals got the bends can be seen from their bones. If bubbles of nitrogen form inside the bone they can cut off its blood supply. This kills the cells in the bone, and consequently weakens it, sometimes to the point of collapse. Fossil (化石) bones that have caved in on themselves are thus a sign that the animal once had the bends.

    Bruce Rothschild of the University of Kansas knew all this when he began a study of ichthyosaur bones to find out how widespread the problem was in the past. What he particularly wanted to investigate was how ichthyosaurs adapted to the problem of decompression over the 150 million years. To this end, he and his colleagues traveled the world's natural-history museums, looking at hundreds of ichthyosaurs from the Triassic period and from the later Jurassic and Cretaceous periods.

    When he started, he assumed that signs of the bends would be rarer in younger fossils, reflecting their gradual evolution of measures to deal with decompression. Instead, he was astonished to discover the opposite. More than 15% of Jurassic and Cretaceous ichthyosaurs had suffered the bends before they died, but not a single Triassic specimen (标本) showed evidence of that sort of injury.

    If ichthyosaurs did evolve an anti-decompression means, they clearly did so quickly—and, most strangely, they lost it afterwards. But that is not what Dr Rothschild thinks happened. He suspects it was evolution in other animals that caused the change.

    Whales that suffer the bends often do so because they have surfaced to escape a predator (捕食动物) such as a large shark. One of the features of Jurassic oceans was an abundance of large sharks and crocodiles, both of which were fond of ichthyosaur lunches. Triassic oceans, by contrast, were mercifully shark- and crocodile-free. In the Triassic, then, ichthyosaurs were top of the food chain. In the Jurassic and Cretaceous, they were prey (猎物) as well as predator—and often had to make a speedy exit as a result.

    Every country may have to consider what, if anything, to do about "global warming". We should understand that the oft-repeated claim that nearly all scientists demand that something dramatic be done to stop global warming is not true.

    Perhaps the most inconvenient fact is the lack of global warming for well over 10 years now. This is known to the warming establishment, as one can see from the 2009 "Climategate" email of climate scientist Kevin Trenberth: "The fact is that we can't account for the lack of warming at the moment and it is an irony that we can't." But the warming is only missing if one believes computer models where so-called feedback involving water vapor and clouds greatly amplifies the small effect of CO2. The fact is that CO2 is not a pollutant and it is a key component of the biosphere ( 生物圈)'s life cycle. Plants get better growth with more of it and part of the increase of agricultural yields in the past century certainly came from additional CO₂ in the atmosphere.

    Although the number of the scientists who are publicly opposed to the claim is growing, many young scientists secretly say that while they also have serious doubts about the global-warming message, they are afraid to speak up for fear of not being promoted or worse.

    Why is there so much passion about global warming? There are several reasons, but a good place to start is the old question "Cui bono?", or the modern update, "Follow the money". Alarmism (危言耸听) over climate is of great benefit to many, providing government funding for academic research, and thus those people who benefit from this fiercely defended their dogma (信条) and the privileges it brought them.

    Every country should support rational ( 合理 的) measures to protect and improve our environment, but it makes no sense at all to back expensive programs that turn away resources from real needs and are based on alarming but shaky claims of "incontrovertible" evidence.

    Sam Allred suffers from a rare and incurable kidney (肾脏)disease. One day, when his sister was playing a song repeatedly, Sam sang along. His sister thought it was funny so she recorded it and posted the video online. The video—and Sam—became a hit. Only 8 years old at that time, he couldn't have expected the response.

    "(The television show) The Doctors called and wanted me on their show so they paid for me to go to California," says Sam, now 13,"and we got to stay in a hotel where all the movie stars stayed."

    During that visit to California, Angle Allred, Sam's mother, had an idea about Sam writing a children's book. Together, she and Sam wrote Opening Hearts, which tells Sam's experience of living with a chronic (慢性的) illness.

    "I wrote the book to teach people to be kinder to people," Sam says.

    Moreover, Sam wanted to send pillows to sick children staying in hospitals around the country to make their stay more comfortable, an idea that came from a time when he was in the hospital.

    "A few kind boys came in with pillows and they gave me one and it meant a lot to me that someone cared about kids in the hospital," says Sam.

    Angie thought of starting a nonprofit organization to provide a way for people to contribute money to realize Sam's ideas. She named the nonprofit organization Kindness for Kids.

    Since then, Sam has taken pillows to children staying at Providence Hospital in Anchorage.

    Sam's father, Scott Allred, owns a small business that contracts (承包) shipping services with FedEx Ground. He asked the company for help.

    "FedEx Ground learned about Sam's pillow project, "says Erin Truxal, manager of public relations for FedEx Ground. "We thought, 'What a perfect way for us to get involved.'"

    The company provided shipping services for Sam to ship about 5,000 pillows to hospitals.

    Sam wants to send more pillows to all of the children's hospitals in every state. His goal is simple: Kids in the hospital as happy as they were before they got sick.
