While dog keepers realize their dogs can read their moods accurately,scientists have always been a little doubtful.Now thanks to some researchers at the University of Veterinary Medicine in Vienna,Austria,we finally have some convincing evidence.

    For their study,biologist Corson Miller and his team exposed eleven selected dogs to digital images of women that were either angry or happy.Half the dogs were rewarded for touching the screen when shown a happy face,while the other half got their treat for selecting those that appeared angry.

    Interestingly,the dogs were not provided with the entire face.Some dogs were shown only upper halves while the others observed lower halves.That's because the scientists believe humans show their emotions on their entire face.

    After some training like how to recognize small differences like the wrinkles between the eyes or the changes in their shape that accompany the happy or angry expressions,the dogs were mostly able to identify the correct expression not only on a familiar face but on a strange face.The researchers concluded the dogs were smart enough to read human emotions.

    They also found those being trained to read angry expressions took a longer time to learn.They guess it may be because dogs find angry faces disgusting,causing them to withdraw quickly.However,once the smart dogs realized they were getting rewarded,the trepidation seemed to disappear.In fact,the dogs had such a good time playing the computer "game" that scientists had a hard time keeping them away from the touch screens after the study was completed.

    The researchers also noticed only dogs with a male owner had a harder time understanding the expressions correctl. Since the touchscreen models were all females, this confirmed what has been observed in previous studies-dogs are more efficient at reading facial expressions of people that are the same gender as their owner.

    A bookseller in Chongqing has been leaving novels on trains and at stations to inspire more commuters(上下班往返的人)to read, after seeing British actress Emma Watson take part in a similar project in London.

    Author and bookstore owner Jiang Lin, 29, randomly placed 40 works along the city's light-rail system on Sunday. Whoever finds a book can read it in public or take it home, but they are encouraged to leave it again on public transportation once they have finished with it. Jiang said, “I considered the needs of commuters," he said. "I hope strangers can feel comforted by the books and feel connected with other readers."

    All 40 books were chosen from Jiang's store, Razor's Edge Book Club, which he opened in the summer, and included fiction and nonfiction, with topics ranging from art and social sciences to philosophy and history Jiang's Books on the Chongqing Light Rail project follows the same model as Books on the Underground, which was started in 2012 and sees “book fairies” leave works on London Tube trains and at stations. Readers are encouraged to share their views on the books. It was revealed on Nov. 1 that Watson, who is best-known for the Harry Potter movie series, is a book fairy.

    “After I read the news about her leaving books on the London Tube, I was so inspired that I immediately decided to do something over the weekend,” Jiang said. However, his decision was so spontaneous that he had no time to make the stickers that are usually placed on each book to identify them as part of the project . Instead, he put a note on the fly page to introduce the concept.

    To his surprise, one of his friends was among those who found his books and posted a picture on WeChat Moments, a social media function on the instant-messaging app. Jiang said more than 20 people have since come onboard and are now working on a more detailed than to spread the love of reading. Although increasing numbers of people read on digital devices, books have not totally gone out of fashion. Jiang mentioned that they needed the support from Chonqing Light Rail Co. to ensure the books to stay there and also hoped the project could be welcomed across the country.

    Talk to the Hand By Lynne Tru

    When did the world get to be so rude? When did society become so inconsiderate (不为他人着想的)? Being rude has become a point of pride for some. Talk to the Hand is a call for politeness.

    Whether you're on a long road trip or stuck in traffic while driving home from work, a low phone battery (电池) could mean disaster for the bored driver. At first, it may seem harmless to plug your phone into your car's USB port. But unless you're desperate, charging your phone in your car might be a big mistake.

    Why? First, the USB port in your vehicle probably provides less electricity than your phone really needs to charge. As a result, your phone might stop working while it charges, or worse—hardly charge at all.

    Brad Nichols, a technician at Staymobile, told Reader's Digest. “This is mostly due to the fact the phone is using more power than the car charger is supplying it.”

    Nichols also says that your phone could receive too much power, especially if you're using a “Cigarette Lighter” port to charge up. Most Cigarette Lighters can supply up to 10 amps (安培), while most chargers use one to three amps. A damaged charger can provide inconsistent power to the phone, leading to sudden power increase that could cause damage to the inside parts, or on the rare occasion, destroy it.

    Charging your phone while on the road could use up your car's battery, too. If your engine is off, but you still use the radio—the phone will draw power from your car's battery as it charges. This usually isn't a big deal for those who own new cars with healthy batteries Nichols says. But if your car is an older model, you might want to avoid charging your phone through its USB port.

    Most importantly, it, s not safe to use your phone while operating a vehicle. “Anytime a person's hands leave the wheel or eyes leave the road, it becomes very dangerous for them and the other people around them,” Nichols says. Bottom line: Play it safe, and wait until you get home to plug in.

    Though pigs may never fly, a two-year-old pig in Franschhoek, South Africa is proving they sure can paint! Meet Pigcasso, the world's first known pig artist whose masterpieces are selling for thousands of dollars to benefit Farm Sanctuary S. A. , Africa's only registered shelter for rescued farm animals.

    Joanne Lefson, who saved Pigcasso from a slaughterhouse(屠宰场) two years ago, discovered the animal's artistic talent accidentally. The South African activist says, of the numerous toys presented to keep the then four-week-old piglet entertained, it was the paintbrushes that seemed to attract her the most. "They were the only thing she didn't eat," Lefson quips.

    The rescuer decided to present the pig with canvas and paint and see what happened. To her delight, Pigcasso began creating works of art that can best be described as "abstract expressionism". Now weighing a hefty(重量）450 pounds, the celebrated pig, who loves to paint the area's scenic landscapes, has a dedicated "studio" at Farm Sanctuary S.A. where she resides. Lefson says, "I do not force her to paint. She paints when she wants to."

    Pigcasso's artwork, which has thus far been sold online, is currently on display at Cape Town's picturesque Victoria ~ Alfred Waterfront. Dubbed "Oink", the pop-up exhibition will run through March 5before heading to London-Paris-Berlin, and Amsterdam. Lefson says its main aim is to highlight the effect of animal agriculture on the planet and inspire change.

    While Pigcasso is the first pig and first nonhuman to headline an exhibition, she is not the first animal to create masterpieces. Elephants, sea lions, and even penguins have shown similar artistic talent--in exchange for some treats, of course!
