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 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 feel 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 least 30 minutes, And while you're at it, actually sit down to eat. If you need some help slowing down, turn on relaxing music. It makes you less likely to rush through a meal.

    Downsize the dishes. Big serving bowls and plates can easily make 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.

    Imagine that you're looking at your company-issued smartphone and you notice an e-mail from Linkedln: “These companies are looking for candidates like you!” You aren't necessarily searching for a job, but you're always open to opportunities, so out of curiosity, you click on the link. A few minutes later your boss appears at your desk. “We've noticed that you're spending more time on Linkedln lately, so I wanted to talk with you about your career and whether you're happy here,” she says. Uh-oh.

     It's an awkward scene. Attrition (损耗) has always been expensive for companies, but in many industries the cost of losing good workers is rising, owing to tight labor markets. Thus companies are making greater efforts to predict which workers are at high risk of leaving ,so that managers can try to stop them. Methods range from electronic monitor to well-designed analyses of employees' social media lives.

     Some of this work may be a reason to let employees to quit. In general, people leave their jobs because they don't like their boss, don't see opportunities for promotion or growth, or are offered a higher pay; these reasons have held steady for years.

    New research conducted by CEB, a Washington-based technology company, looks not just at why workers quit but also at when. “We've learned that what really affects people is their sense of how they're doing compared with other people in their peer group, or with where they thought they would be at a certain point in life, says Brian Kropp, who heads CEB's HR practice. “We've learned to focus on moments that allow people to make these comparisons.”

Technology also provides clues about which star employees might be eyeing the exit. Companies can tell whether employees using work computers or phones are spending time on (or even just opening e-mails from) career websites, and research shows that more firms are paying attention to these things. Large companies have also begun searching for badge swipes (浏览痕迹)—- employees' use of an ID to enter and exit the building or the parking garage—to identify patterns that suggest a worker may be interviewing for a job.

    For centuries, mankind and dogs have suffered from a communication failure. We can tell dogs what we want them to do and sometimes they comply, but we've always struggled when it comes to understanding the true meaning of their barks and whimpers. There is exciting news now – a dog translator has been invented to help you communicate with your furry friend.

    Researchers at North Carolina State University have fashioned some kind of miracle dog translator body harness(束腰带). What's special about it is that it doesn't just rely on the dog's vocalizations to interpret what Fido is banging on about.

    Oh no – this miracle harness reads and interprets the ordinary dogs' body language as well, giving us a full two-way dog communication experience.

    Researcher David Roberts says: "Dogs communicate primarily through body language, and one of our challenges was to develop sensors that tell us about their behavior by observing their posture remotely."

    Sensors on the harness monitor the dog's heart rate and body temperature and software builds up a vocabulary, letting the human know what the dog is feeling.

    What would dogs say if they could talk to us? The human can even communicate back through the harness thanks to vibration motors, supposedly by tapping into the dog's senses so that it can understand what you're trying to say to it.

    The dog harness is designed for dogs involved in search and rescue and other front-line work, but it's got us dreaming of a beautiful future, one where humans and dogs can co-exist as equals, with the dog able to fully express itself at all times.

    Researchers at the University of York in England published their findings on facial recognition that, on average, people can remember as many as 5,000 faces.

    There have been many studies recently on facial recognition technology. But the authors of this study say theirs is the first time that scientists have been able to put a number to the abilities of humans to recognize faces. Rob Jenkins, leader of the research, said the researchers' study centered on "the number of faces people actually know." and were not able to discover whether there is a "limit on how many faces the brain can handle."

    Jenkins said the ability to tell individual people apart is "clearly important." In today's modern world of big cities, we meet and deal with thousands of people. The study suggests our facial recognition abilities help us to deal with the many different faces we see on the screens, as well as those we know. The results of the study give a baseline for comparing the "facial vocabulary" of humans with facial recognition software.

    Today, facial recognition technology is used in many ways, including by law enforcement agencies to prevent crime and violence. Governments use it to keep secret areas secure and, in extreme cases, control populations. Some governments use the software to watch people and find out where they go and what they do. Even Facebook uses facial recognition. For example, when you name a friend, Facebook technology may recognize the person's face from a different picture you had shared before.

    For the human study, people spent one hour writing down as many faces from their personal lives as possible. At first, they found it easy to come up with many faces. But by the end of the hour, they found it harder to think of new ones. Their change in speed let the researchers estimate when they would have run out of faces completely. 1,000 to 10,000 faces remembered. People who took part in the study were also shown thousands of photographs of famous people. Researchers asked them which ones they recognized. To make sure they knew these people, researchers required them to recognize two different photos of each famous person. The results showed that the participants knew between 1,000 and 10,000 faces.

    How do they explain such a wide range? Jenkins said one explanation may be that some people have a natural ability for remembering faces. "There are differences in how much attention people pay to faces and how well they process the information." Also it could be because of different social environments. Some people may have grown up in more populated places. So, they may have had more social contact throughout their lives.

    Researchers think age may be an interesting area for further research. “It would be interesting to see whether there is a peak age for the number of faces we know”, Jenkins said. He said it is possible that we gather more faces throughout our lifetime. But, he added, there also may be an age at which we start to find it harder to remember all of those faces.
