A new study has discovered that meditation（冥想）and oxygen sport together reduce depression. The Rutgers University study found that this mind and body combination, done twice a week for only two months, reduced the symptoms for a group of students by 40 percent.

    “We are excited by the findings because we saw such a meaningful improvement in both clinically depressed and non-depressed students,” said lead author Dr. Brandon Alderman. “It is the first time that both of these two behavioral ways have been looked at together for dealing with depression.”

    Researchers believe the two activities have an interactive effect in combating depression. Alderman and Dr. Tracey Shors discovered that a combination of mental and physical training (MAP) enabled students with major depressive disorder not to let problems or negative thoughts defeat them.

    Rutgers researchers say those who participated in the study began with 30 minutes of focused attention meditation followed by 30 minutes of oxygen sport. They were told that if their thoughts drifted to the past or the future they should refocus on their breathing, enabling those with depression to accept moment-to-moment changes in attention.

    Shors, who studies the production of new brain cells in the hippocampus—part of the brain involved in memory and learning—says scientists have shown in animal models that oxygen sport exercise keeps a large number of certain cells alive.

    The idea for the human intervention（干预）came from her laboratory studies, she says, with the main goal of helping individuals acquire new skills so that they can learn to recover from stressful life events.

    By learning to focus their attention and exercise, people who are fighting depression can acquire new learning skills that can help them process information and reduce the overwhelming recollection of memories from the past, Shors says.

    “We know these treatments can be practiced over a lifetime and that they will be effective in improving mental health.” said Alderman. “The good news is that this intervention can be practiced by anyone at any time and at no cost.”

    Humans have been keeping animals as pets for tens of thousands of years, but Dr Jean-Loup Rault, an animal scientist at the University of Melbourne in Australia, believes new companions are coming: robot pets.

    “Technology is moving very fast,” Rault told ABC News, “The Tamagotchi in the early 1990s was really the first robotic pet, and now Sony and other big companies have improved them a lot.”

    This may not sit well with pet lovers. After all, who would choose a plastic toy over a lovely puppy? But Rault argues that the robotic kind has a lot going for it: “You don't have to feed it, you don't have to walk it, it won't make a mess in your house, and you can go on a holiday without feeling guilty.” The technology also benefits those who are allergic to pets, short on space, or fearful of real animals.

    It's not clear whether robot pets can replace real ones. But studies do suggest that we can bond with these smart machines. People give their cars names and kids give their toy animals life stories. It's the same with robots. When Sony stopped its repair service for its robot dog Aibo in March 2014, owners in Japan held funerals.

    As an animal welfare researcher, Rault is concerned about how robotic pets could affect our attitudes towards live animals. “If we become used to a robotic companion that doesn't need food, water or exercises, perhaps it will change how humans care about other living beings,” he said.

    So are dogs and cats a thing of the past, as Rault predicts? For those who grew up with living and breathing pets, the mechanical kind might not do. But for our next generation who are in constant touch with smart technology, a future in which lovely pets needn't have a heartbeat might not be a far-fetched dream.

    A parent might place his daughter's drawing on the fridge out of a love for his child rather than for the wonderful image, but for many people, that children art is actually quite amazing. In fact, adult artists were often inspired by children's drawing. For the museum-goers out there who tend to point to a piece of modern art and say, “My kid could have made that !”It's worth remembering that often, that's actually just what the artist had in mind.

    For many kids, drawing is exciting not because of the final product it leads to, but because they can live completely in the world of their drawing for a few minutes. Even children are scribbling(涂鸦), they're representing through action, not through pictures. Liane Alves, a prekindergarten teacher, recalled a student who presented her with a drawing featuring a single straight line across the page. Alves assumed the child hadn't given too much thought to the drawing until he explained that the line was one of the stems (茎) from The Princess and the Pea, one of the fairy tales they read in class.

    Maureen Ingram, who's a preschool teacher at the same school,said her students often tell different stories about a given piece of art depending on the day, perhaps because they weren't sure what they intended to draw when they started the picture. “We as adults will often say, 'I'm going to draw a horse, 'and we set out. . . and get frustrated when we can't do it, ”Ingram said. “Children seem to take a different approach, where they just draw, and then they realize, 'it is a horse. '”

    And what about those odd or scary-looking drawings? Does that mean kids are telling themselves stories that are odd or scary? It's hard to say, but it's rarely a good idea to over-interpret it. Ellen Winner, a psychology professor, pointed to parents who worry when their kid draws a child bigger than the adults. What's most important to remember is that“children's art has its own logic,” Winner said. “Children are not being crazy. ”

    A ten-year-old from Howell, Michigan is being praised as a hero thanks to his persistence (坚持) that led to saving the life of an elderly neighbor. The event happened late in an evening when Danny DiPietro was being driven home from hockey practice by his mom.

    That's when the young boy noticed an open garage (车库) and a figure that he believed was a dog outside an apartment building near his house. Given the freezing cold weather, the young boy got a feeling that something was not right. But instead of dismissing it like most kids his age would have, he insisted that his mother, Dawn, find out what was going on. Dawn tried to make Danny believe that no one would leave a dog out in such cold weather, but he refused to take no for an answer.

    Dawn finally gave in and decided to drive to the area with the family dog and see if there was any truth to Danny's hunch (直觉). Sure enough, as she got closer to the apartment building she noticed a garage that was wide open and someone waving madly for help. Upon getting there, she realized that it was not a dog the young boy had seen, but Kathleen St. Onge. The 80-year-old had fallen down on some ice in her garage and had been lying there for two hours, unable to get up.

    Dawn rushed home to get her husband to help and called 911. The two then returned with some blankets to cover Ms. St. Onge, while they waited for the ambulance (救护车) to arrive. Though still in hospital, the elderly woman is recovering well and forever grateful to Danny, for following up on his hunch!

    ※ Damon, May 21, 2019

    The price is great with an extra $ 20 off and this new Kindle is smaller in my hands than my old one. I was sad to lose my old Kindle, but this one is terrific.

    ※ Jason, January 26, 2019

    I miss the original Kindlers size—this one is too small. Also, the screen is overly sensitive and things pop up (弹出) and the battery doesn't last as long as the original Kindle. But my biggest disappointment is that this Kindle doesn't allow you to transfer everything from the original Kindle、so I lost all of the information from my old one. Overall, disappointing.

    ※ Susan, November 17, 2018

    I had the original Kindle, and the battery lasted for weeks. This battery only seems to last a few days, however. The other problem I have with this version of the Kindle is the touch screen. It is annoying when you are reading and start turning the wrong way. Sometimes, it's hard to get the page to turn the way you'd like it to.

    The term "crocodile tears" refers to insincere sadness. This term has an etymology dating back several centuries. As early as the fourth century, crocodile tears are referenced in the literature with the meaning of insincere sorrow. It is said that crocodiles weep while eating their hunted animals because they are sad; however, this sadness is not honest.

    The term crocodile tears became widely popular after it was documented in a fifteenth-century book titled The Voyage and Travel of Sir John Mandeville, Knight. A passage from the book reads: "These crocodiles kill men and they eat them weeping."

    As you may already know, crocodilians(鳄目动物) likely feel bad about little—especially feeding. However, the assumption of the crocodile-tears metaphor may be true. In a 2007 paper published in BioScience titled "Crocodile Tears: And they eat them weeping", researchers observed 7 crocodilians in cages during feeding time at a reserve (4 caimans and 3 American alligators). The researchers observed the crocodilians outside of water at feeding stations to better find out whether tearing developed.

    Five of the 7 crocodilians developed something like tears in their eyes before, during or after feeding. The researchers suggest that these crocodile tears occur because a crocodilian hisses (发出嘶嘶声) while it eats, and this hissing forces air through the spaces in the bone behind the nose and out the eye, in the process picking up nasolacrimal secretions (鼻泪管分泌物.)

    In humans, crocodile tears is a medical condition that causes a person to tear up while eating. Crocodile tears typically occur because of a temporary loss of facial control due to damage of the facial nerve. Specifically, when the facial nerve grows again, it does so incorrectly thus resulting in tears during chewing food.
