People born in winter are more likely to suffer mental health disorders, according to a recent study carried out by researchers at Vanderbilt University in Tennessee.

    Researchers raised baby mice from birth to weaning (断奶) in either “summer” light cycles of 16 hours of light and 8 hours of dark or “winter” cycles of 8 hours of light and 16 hours of dark. A third group experienced 12 hours of light and 12 hours of dark a day.

    Then half the winter mice stayed in a winter cycle, while half switched to a summer schedule. The summer mice were similarly split. The mice raised in equal periods of light and dark were split into three groups, one of which stayed on the 12­hour schedule, one of which joined the winter group, and one of which joined the summer group.

    After 28 days, it turns out the summer­born mice behaved the same whether they stayed on the summer cycle or switched to winter. But among the winter­born mice, those stayed in winter kept their previous schedule, while those that switched to summer stayed active for an extra hour and a half, which indicates that mice born and weaned in a winter light cycle showed dramatic disruptions（破坏） in their biological clocks.

    The finding is the first of its kind in mammals, and it could explain why people born in winter are at higher risk for mental health disorders.

    “We know that the biological clock regulates(管理) mood in humans,” said study researcher McMahon. “If the mechanism (机制) similar to the one that we found in mice operates in humans, then it could not only have an effect on a number of behavioral disorders, but also have a more general effect on personality.”

    When pups are between 2 and 3months old, their mothers will abandon them for any number of reasons. With no mother to watch out for them, infant (婴儿) mortality of pups under one year skyrockets (飞涨) to around 90%. So, only about 10% of motherless, homeless pups survive.

    Without mothers, how are these abandoned pups supposed to survive? For the study, researchers Clive Wynne at Arizona State, Nadine Chersini at Utecht University, and Nathan Hal at Texas Tech University brought in 51 college students and asked them to rate the attractiveness of headshots (头部特写) of puppies at different ages.

    The pups peaked at different ages, but they were all ranked likable between six to eight weeks, since newly abandoned pups are competing with each other for human heartstrings (怜悯), evolution says they should be most likable around 6 and 11 weeks. This is around the time they are weaned (断奶) and let go of by their mothers.

    There are a few characteristics that humans find particularly adorable across species: big, forward-facing eyes, floppy and unstable limbs (肢), and a soft, rounded body shape. We're also keen to scream when animals have large heads in comparison to their bodies, and this reaction goes back to evolution.

    Called kinderschema (婴儿萌), these qualities are also apparent in human babies and necessary for their survival. The characteristics activate the decision-making part of the brain to encourage you to protect and nurture the baby. At the same time, the brain's pleasure center releases dopamine (多巴胺). With these two reactions, your brain makes you want to protect the baby and rewards you for doing so. With your protection, the baby can survive.

    Through your childhood and, let's be honest, most of your adult life, you may have wondered—how do you get to Sesame Street? After 50 years, the answer has finally been revealed.

    New York City's Official Sesame Street

    In the past, there was guessing about the true location of the street, like Harlem or Alphabet City since both neighborhoods resembled Sesame Street in appearance and population makeup. Recently, in honor of the children's television show's 50th anniversary, New York City Mayor Bill de Blasio declared that West 63rd Street between Central Park West and Broadway will now officially be known as Sesame Street, close to the Sesame Workshop office.

    A Year-long Celebration for the 50^th Anniversary

    Since 1969, the children's television show Sesame Street has been a pioneering force in media and education, dealing with issues like racism, loss, poverty and living with a disability. With a mission to help kids everywhere grow smarter, stronger, and kinder, Sesame Street has brought the life-changing benefits of early learning to children across the globe for 50 years. Today, we reach kids in 150 countries and 70 languages and we're celebrating our landmark anniversary with fans and families all year long!

    Events and Activities Throughout 2019

    Fans and families around the world can join their favorite furry friends in celebrating Sesame Street's past, present, and future, with:

    A 50th television season which focuses on the power of possibilities, empowering kids to take safe risks and learn from their mistakes.

    A nationwide road trip where Sesame Street characters and friends host community events in ten cities around the country.

    A research report that will explore an important issue facing kids and families today.

    Celebrity and fan-fueled social media campaigns showcasing favorite Sesame Street memories.

    New corporations across fashion, lifestyle, and themed entertainment for fans of all ages.

    A November star-studded prime-time special, whose contents include new takes on classic scenes and visits from Sesame Street icons.

    It has been a year since I found out my friend had passed away. I still store his phone number, even though I know calling the number will never reach him again. I feel like if I deleted (删除) his phone number, it would mean he was really gone.

    Over the past few years, we have planned to travel together just to see the dolphins in the sea. However, for some reasons it didn't happen, yet I always took his calls over the years. We shared a lot of interests.

    When I knew that he had been diagnosed (诊断) with a very serious illness and was in hospital, I remembered sending messages to him. I did not receive a message back, so I left a voicemail. A week later, I sent him a message once again. However, I still didn't get a reply. I thought he was busy. During the next several months I was very busy, too. Suddenly, in that mid-summer, I received a short message: "Sorry, Marlynn, He has passed away."

    I was very sad and surprised at the words. I was very sad and regretful. I regretted that I let the months pass without trying again. I worked with many people who had also lost their best friends. The sadness is often unspeakable. There is guilt (内疚), helplessness and sadness that is difficult to put into words.

    Now I try to be grateful for the times and memories we have. I realize the best thing that we can do is value the ones we love.

This famous site features one of the largest and most representative collections of Buddhist architecture and art in China. It was rated as a 5A-class tourist attraction in 2010.

The Lingshan Grand Buddha is an 88-meter-high open-air bronze statue of Sakyamuni. It is 17 meters higher than the Grand Buddha at Leshan Mountain. It is part of the pattern of Five Buddhas in five directions together with the Big Buddha at Lantau Island in Hong Kong to the south, the Grand Buddha at Leshan Mountain to the west, the Grand Buddha in Yungang Caves to the north and the Grand Buddha at the Longmen Caves in the central area. At the feet of the Grand Buddha, you can feel the loftiness (雄伟) and dignity of Buddhism.
