More and more Americans are showing an interest in healthy and locally-produced food. As the interest increases, raising chickens has been gaining popularity in some American cities.

 “Look, we get three eggs this time.”

    Collecting eggs is a daily pleasure for the Hurst family. Naomi Hurst says her family started to raise chickens in back of their home in Maryland a month ago.

   “We have wanted to try having backyard chickens for a couple years now. And really just didn't have the time to build my own coop（鸡笼；鸡舍） and  look out where to buy chickens. And then we met Rent a Coop,” said Naomi Hurst. Rent a Coop is a chicken rental business. Tyler Phillips launched the company with a partner 18 months ago. It comes with a mobile coop on wheels, two egg-laying hens, feed, bedding, water bowl, feed bowl, and our 24-hour chicken hotline. You can call with any questions. The price is 185 dollars for four weeks. After the four weeks passed, individuals can extend the rental agreement, return everything or purchase the animals and supplies.

Tyler Phillips designs and makes the coops. He says he wants to do as little damage as possible to the environment.

 “We always try to have as many recycled materials as possible. And I want the coops to be safe for kids. I want the chickens to be comfortable and they have access to the grass while being inside the coop. I want it to be easily movable, light weight,” he said.

Some cities require people have large pieces of land, if they want to raise farm animals. Others require an agreement with neighbors, limit the number of chickens, or, even ban the birds.

  Tyler Phillips expects that would change as interest in small poultry (家禽) coops grows. 

“I see cities around the D. C. area changing laws almost monthly and different cities will change the law to being prochicken(赞成养鸡). That is happening all around the United States,” he said,

He believes that there will be chicken rental businesses in most American cities within five years.

How Room Designs Affect Our Work and Feelings

    Architects have long had the feeling that the places we live in can affect our thoughts, feelings and behaviors. But now scientists are giving this feeling an empirical(经验的，实证的) basis. They are discovering how to design spaces that promote creativity, keep people focused and lead to relaxation.

    Researches show that aspects of the physical environment can influence creativity. In 2007, Joan Meyers-Levy at the University of Minnesota, reported that the height of a room's ceiling affects how people think. Her research indicates that higher ceilings encourage people to think more freely, which may lead them to make more abstract connections. Low ceilings, on the other hand, may inspire a more detailed outlook.

    In additions to ceiling height, the view afforded by a building may influence an occupant's ability to concentrate. Nancy Wells and her colleagues at Cornell University found in their study that kids who experienced the greatest increase in greenness as a result of a family move made the most gains on a standard test of attention.

    Using nature to improve focus of attention ought to pay off academically, and it seems to, according to a study led by C. Kenneth Tanner, head of the School Design & Planning Laboratory at the University of Georgia. Tanner and his team found that students in classrooms with unblocked views of at least 50 feet outside the window had higher scores on tests of vocabulary, language arts and maths than did students whose classrooms primarily overlooked roads and parking lots.

    Recent study on room lighting design suggests than dim(暗淡的) light helps people to loosen up. If that is true generally, keeping the light low during dinner or at parties could increase relaxation. Researchers of Harvard Medical School also discovered that furniture with rounded edges could help visitors relax.

    So far scientists have focused mainly on public buildings. "We have a very limited number of studies, so we're almost looking at the problem through a straw(吸管)," architect David Allison says. "How do you take answers to very specific questions and make broad, generalized use of them? That's what we're all struggling with."

    The Boy Made It!  One Sunday, Nicholas,a teenager, went skiing at Sugarloaf Mountain in Maine．In the early afternoon, when he was planning to go home, a fierce snowstorm swept into the area．Unable to see far,he accidentally turned off the path．Before he knew it,Nicholas was lost,all alone!He didn't have food,water,a phone,or other supplies．He was getting colder by the minute．

    Nicholas had no idea where he was．He tried not to panic．He thought about all of the survival shows he had watched on TV．It was time to put the tips he had learned to use．

    He decided to stop skiing．There was a better chance of someone finding him if he stayed put．The first thing he did was to find shelter from the freezing wind and snow．If he didn't,his body temperature would get very low,which could quickly kill him．

    Using his skis,Nicholas built a snow cave．He gathered a huge mass of snow and dug out a hole in the middle．Then he piled branches on top of himself,like a blanket,to stay as warm as he could．

    By that evening,Nicholas was really hungry．He ate snow and drank water from a nearby stream so that his body wouldn't lose too much water．Not knowing how much longer he could last,Nicholas did the only thing he could—he huddled(蜷缩)in his cave and slept．

    The next day,Nicholas went out to look for help,but he couldn't find anyone．He followed his tracks and returned to the snow cave,because without shelter,he could die that night．On Tuesday,Nicholas went out again to find help．He had walked for about a mile when a volunteer searcher found him．After two days stuck in the snow,Nicholas was saved．

Nicholas might not have survived this snowstorm had it not been for TV．He had often watched Grylls' survival show —-Man vs．Wild． That's where he learned the tips that saved his life．In each episode(一期节目) of Man vs．Wild, Grylls is abandoned in a wild area and has to find his way out．

    When Grylls heard about Nicholas' amazing deeds,he was super impressed that Nicholas had made it since he knew better than anyone how hard Nicholas had to work to stay alive．

    Who could have imagined that a treadmill(跑步机)on wheels would one day become a thing? Lopifit is an unusual means of transportation that allows you to power an electric bicycle by walking on a treadmill.

    Lopifit founder Bruin Bergmeester says it all started when he asked himself the question. "How can I use a treadmill outdoors?" He eventually came up with a design, to which he added an electric engine, and Lopifit was born. The treadmill bicycle is similar to a typical electric bicycle in that the motor only works when the rider puts power in as well. The Lopifit senses it when you walk on the treadmill and uses the motor to turn a drive chain at the back part of the treadmill, helping you reach a top speed of 17 miles per hour.

    To use the Lopifit, simply turn on the battery and use your feet to slide the treadmill backwards and activate (激活) the motor. Then get on and enjoy the ride! If you need speed, just walk on the treadmill, and if you want to coast, all you have to do is stay still and admire the view. To stop, you have two hand brakes available.

    The Lopifit first hit the streets in 2014 and, unsurprisingly, became an instant hit. That was actually quite challenging for the company, because it started get inquiries and calls for orders, but it was nowhere near ready for mass production. The unique treadmill bicycle became available this year, and Lopifit is struggling to keep up with demand, despite the high price tag of $ 2,115.

    But despite having a very loyal fan-base of so-called Lopifitters, the creative means of transportation also has naysayers who simply consider the invention stupid and unnecessary. They basically believe that if you're going to walk, you might as well do it the old-fashioned way. But the Lopifit does have the unique advantage of helping you walk really fast without breaking a sweat, or walking at cycling speed, if you will.

    People who play computer games to train their brains might as well be playing Super Mario, new research suggests.

    In a six-week study, experts found people who played online games designed to improve their cognitive(认知的) skills didn't get any smarter.

    More than 8,600 people aged 18 to 60 were asked to play online brain games designed by the researchers to improve their memory, reasoning and other skills, for at least 10 minutes a day, three times a week.

    They were compared to more than 2,700 people who didn't play any brain games, but spent a similar amount of time surfing the Internet. All participants were given an "IQ test" before and after the experiment.

    Researchers said the people who did the brain training didn't do any better on the test after six weeks than people who had simply been on the Internet.

    "If you're(playing these games) because they're fun, that's absolutely fine," said Adrian Owen, assistant director at Britain's Medical Research Council. "But if you're expecting these games to improve your IQ, our data suggests this isn't the case."

    Computer games that are supposed to improve memory, reasoning and other cognitive skills are played by millions of people worldwide, though few studies have examined if the games work.

    "There is precious little evidence to suggest the skills used in these games transfer to the real world," said Art Kramer, a professor of psychology at the University of Illinois, US.

    Instead of playing brain games, Kramer said people would be better off getting some exercise. He said physical activity can help produce new brain cells.

    Other experts said brain games might be useful, but only if they weren't fun.

    "If you set the level for these games to a very high level where you don't get the answers very often and it really annoys you, then it may be useful," said Philip Adey, a professor of psychology at King's College in London.

    If people are enjoying the brain games, Adey said they probably aren't being challenged and might as well be playing a regular video game.

    He said people should consider learning a new language or sport if they really want to improve their brain power. "To stimulate(激发) the intellect, you need a real challenge," Adey said, "Getting smart is hard work."
