Article: What could be cuter than your puppy giving his doggy friend a kiss on the nose? Nothing, really. But is your dog actual-fly planting a kiss on his friend? Yes, but that's only one of the reasons your dog may lick another dog's nose. Here are some other reasons why your dog may lick another dog's nose. During an introduction, a shy and lower-ranking dog will lower his head, avoid direct eye contact and gently extend his tongue to lick the nose of a more confident and high-ranking dog. The first dog licks the nose of the second dog to simply make it know that:he comes in peace. Dogs who are already friends will also trade kisses. Two strongly bonded dog pals will lick and clean each other. They give each other "dog kisses" showing friendship. Puppies also "kiss" their mothers, but it's not a gesture of love. When puppies stop suckling their mothers' tits for milk and start to eat semisolid food instead;they lick their mothers' mouths and noses in the hope of getting the mother to regurgitate some semi-digested food. So how to help your _ dog make friends with other dogs? You can carefully select confident-but-friendly and good-tempered dogs to play with your shy dog, to help him develop his social skills. Also consider taking him to a special training class that focuses on socialization and positive training technique. Do not disturb them when your two dogs play "kiss" briefly with each other. Sit back and enjoy this display of friendship. Then call them over and have them do a command such as "sit'' or "shake paws". Offer them treats as a reward for being good to each other. If you foster a dog and have three or more resident dogs, introduce the foster dog to your brood dog one at a time and let muzzle licking between them happen naturally. Start with your least reactive or most friendly dog. Never force an in production between the dogs because this can deepen the foster dog's submissiveness or spark a fight.

Article: Right now in China, talks on the street have been about the strange weather and it's raising a lot of concerns. A heavy haze has blanketed many cities in the northern and southern parts of the country in part of an unusual weather system that's descended on the nation. The haze stretches over a vast area, from Hebei and Shan-dong Provinces in the north all the way to Zhejiang, Anhui, Jiangsu, Hunan and Fujian provinces in the south. At its worst, the smog is reducing visibility to less than 200 meters and disrupting traffic, both on the ground and in the air. The weather front has also led many to worry about the possible health impacts. Many cities are waking up to another day covered by a dense haze. In Beijing, drivers have to keep their lights on even though it's already past eight o'clock in the morning. Even driving at very slow speeds, the roads can still be very dangerous. In some of the worst hit areas, drivers can't even tell the colors of traffic signals. Authorities have stepped in to close off many highways across the troubled region. In Shandong Province, the highways that are open are backed up for miles. And traffic police have stepped up their patrols. In the region's airports, flights information boards have gone red. A huge number of flights have been delayed or cancelled, nearly three hundred in Beijing alone, leaving thousands of passengers stranded. Some are more frustrated than impatient. Passenger from Jinan airport, Shangdong province, said: "I've been waiting for more than five hours. It's Mother Nature, so there's really nothing we can do." The airport is urging passengers to confirm with their carrier whether their flight will still take off as scheduled. Back on the city streets, people are wearing breathing masks to get free from any ill effects. Fog has cleared a little in Shanghai. But damage has already been done. Shanghai resident said: "I've been wearing the mask, but still, my throat feels sour and itchy. I think it's because of the weather." The weather forecast predicts a cold front is about to sweep across central and eastern China tomorrow. Many are hoping that this will clear away the depressive haze as well as the harm it brings.

In the first, a timed task that required memorizing a list followed by a short test, subjects believed they had control over the outcome. In the second, they weren't in control. They had to sit through a bloody video on surgical procedures. Those who did the memory test had an increase levels of immunoglobulin A, an antibody that's the body's first line of defense against germs. However, the video-watchers experienced a fall in the antibody. Stress encourage body to produce certain stress hormones . In short bursts these hormones have a positive effect, including improved memory function. "They can help nerve cells handle information and put it into storage," says Dr. Bruce McEwen of Rockefeller University inNew York. But in the long run these hormones can have a harmful effect on the body and brain. "Continuous stress is not good for you," says Richard Morimoto, a researcher at Northwestern University in Illinoisstudying the effects of stress on one's life, "It's the occasional burst of stress or brief experience of stress that could be protective.
