If you've not heard that the decade-old princess-culture is causing problems—especially if you're a parent—you must be actively working to avoid it.

    The latest study adding fuel to the fire comes out of Brigham Young University and finds that the Disney princess obsession can be harmful to girls.

"I think parents think that the Disney princess culture is safe. That's the word I hear time and time again—it's safe." Lead study author Sarah M. Coyne of the Mormon institution in Utah noted in a press release. "But if we're fully jumping in here and really embracing (accepting) it, parents should really consider the long-term impact of the princess culture."

    So, what's the problem this time around? Same as always, confirmed the study, published in the journal Child Development, which involved the assessment of 198 preschoolers: Lots of engagement with princess culture (whether through moves or toys) can lead to gender-stereotypical(性别定性) behavior as well as self-critical body image.

The strict gender stereotypes can hold girls back. "They feel like they can't do some things," Coyne said, "They're not as confident that they can do well in math and science. They don't like getting dirty, so they're less likely to try and experiment with things."

On the other hand, "Disney princesses represent some of the first examples of exposure to the thin ideal," Coyne said. "As women, we get it our whole lives, and it really does start at the Disney princess level, at age 3 and 4."

So, what should a parent do? Try his or her best to avoid all princesses for the entire of a girl's childhood? I'd say, have moderation in all things, have your kids involved in all sorts of activities, and just have princesses be one of many, many things that they like to do and engage with." Coyne suggested. "This study has changed the way I talk to my daughter, the things I focus on, and it's been really good for me as a parent to learn from this study," Coyne said. "I usually can't say that my research findings have such a personal impact on my life."

With around 100 students scheduled to be in that 9:00 am Monday morning lecture, it is no surprise that almost 20 people actually make it to the class and only 10 of them are still awake after the first 15 minutes; it is not even a surprise that most of them are still in their pajama's(睡衣). Obviously, students are terrible at adjusting their sleep cycles to their daily schedule.

    All human beings possess a body clock. Along with other alerting systems, this governs the sleep/wake cycle and is therefore one of the main processes which govern sleep behaviour. Typically, the preferred sleep/wake cycle is delayed in adolescents, which leads to many students not feeling sleepy until much later in the evenings. This typical sleep pattern is usually referred to as the “night owl” schedule of sleep.

This is opposed to the “early bird” schedule, and is a kind of disorder where the individual tends to stay up much past midnight. Such a person has great difficulty in waking up in the mornings. Research suggests that night owls feel most alert and function best in the evenings and at night. Research findings have shown that about 20 percent of people can be classified as “night owls” and only 10 percent can be classified as “early birds” —— the other 70 percent are in the middle. Although this is clearly not true for all students, for the ones who are true night owls, this gives them an excellent excuse for missing their lectures which unfortunately fall before midday.

    The medical world is gradually realizing that the quality of the environment in hospitals may play an important role in helping patients to get better.

    As part of nationwide effort in Britain to bring art out of the museum and into public places, some of the country's best artists have been called in to change older hospitals and to soften the hard edges of modern buildings.

    Of the 2,500 national health service hospitals in Britain, almost 100 now have very valuable collections of present art in passages (走廊), waiting areas and treatment rooms.

    These recent movements first started by one artist, Peter Senior, who set up his studio at a Manchester hospital in northeastern England during the early 1970s. He felt the artist had lost his place in modern society, and that art should be enjoyed by a wider audience. A common hospital waiting room might have as many as 5,000 visitors each week. What a better place to hold regular exhibition of art! Senior held the first exhibition of his own paintings in the outpatients waiting area of the Manchester Royal Hospital in 1975. Believed to be Britain's first hospital artist, Senior was so much in demand that a team of six young art school graduates soon joined him.

    The effect is surprising. Now in the passages and waiting rooms, the visitor experiences a full view of fresh colors, playful images and restful courtyards.

    The quality of the environment may reduce the need for expensive drugs when a patient is recovering from illness. A study has shown that patients who had a view onto garden needed half the number of strong painkillers compared with patients who had no view at all or only a brick wall to look at.

    On a flight from Dallas, Texas, to Cincinnati, Ohio, to visit a friend in 2013, event planner Paige Chenault daydreamed about the grand birthday parties she'd throw for her daughter one day. (Paige was five months pregnant at the time.) Then, flipping through a magazine, she saw a photo of an impoverished Haitian boy, skinny. "I thought, this kid has nothing," Paige says.

    The image stayed with her, and she resolved to do something to help. "I decided I would use my talents to throw birthday parties for homeless kids," Paige says. For the next four years, Paige and her husband, Colin, took time out from parenthood to visit shelters to determine how best to pull off the parties.

    Finally, in January 2017, Paige launched the Birthday Party Project, a nonprofit organization, and recruited friends and family to help decorate Dallas's 75- occupant Family Gateway Shelter with balloons and streamers, celebrating the birthdays of 11 boys and girls, with 60 more homeless kids in attendance. "That first party was better than I could have ever imagined," says Paige.

    Now Paige and her staff of three paid employees work with regional volunteers to plan monthly themed parties at 15 shelters across the country, some of which house abused or abandoned kids. Each child celebrating a birthday that month gets a $30 gift, a decorative place mat, and an individual cake or cupcake.

    One of Paige's favorite parts of each party is when the kids make a wish and blow out the candles. "They rarely get a chance to dream big," says Paige.

    Her daughter, Lizzie, now seven, often helps out at the parties. Paige says, "The one thing I've always wanted is for my kid to be generous."

    I was getting ready to go to bed when the phone rang. This could not be good. My mind raced through the list of family members who might need help, but the voice was hardly familiar.

    "Lindy, this is Lesley." I don't know Lesley well. We did occasionally speak with each other, but to say we were friends was not appropriate. I asked what she needed. Perhaps something really awful caused her to reach someone she barely knew. Instead, she asked me, "Do you have room for a turkey? In your freezer?" We had lots of room in our freezer, and in fact, too much. "Sure," I responded, "did your freezer break down?" "Not exactly," Lesley replied, but I will explain when I arrive."

    Minutes later came a huge freezer truck. Lesley stepped down and explained the lease (租约) of the grocery store her husband serviced had run out and that they had to empty all the freezers that very night. Thinking it was a shame to throw away all this good food, they decided to drop off food to anyone she could think of. Noticing our freezer was pretty empty, Lesley asked to fill it up. Our home was their last stop and anything left would have to be put in our freezer. An hour later, everything finished, I asked her, "When will you come back for all this?" Lesley laughed, "We don't want it back. It is yours! Thanks for helping us out!" Then they waved goodbye and drove away.

    "For helping them out?" We opened our freezer door. Inside were all expensive foods we never bought but often longed to try. We were struggling to buy groceries, yet it was not something we shared with anyone. However, our needs were met in an unexpected way, by that call, "Do you have room for a turkey?"

    Why elephants rarely get cancer is a mystery that has confused scientists for decades. A study was led by researchers at Huntsman Cancer Institute (HCI) at the University of Utah and Arizona State University, including researchers from the Ringling Bros. Center for Elephant Conservation may have found the answer. According to the results, elephants have 38 additional modified copies of a gene (基因) that encodes p53, a well-defined tumor (肿瘤) suppressor, as compared to humans, who have only two. Further, elephants may have a more powerful mechanism for killing damaged cells that are at risk for becoming cancerous. In isolated elephant cells, this activity is doubled compared to healthy human cells, and five times that of cells from patients with Li-Fraumeni Syndrome, who have only one working copy of p53 and more than a 90 percent lifetime cancer risk in children and adults. The results suggest extra p53 could explain elephants' increased resistance to cancer.

    "Nature has already figured out how to prevent cancer. It's up to us to learn how different animals overcome the problem so we can adapt those strategies to prevent cancer in people," says co-senior author Joshua Schiffman, M.D., pediatric oncologist (肿瘤学家) at Huntsman Cancer Institute, University of Utah School of Medicine, and Primary Children's Hospital.

    According to Schiffman, elephants have long been considered a walking problem. Because they have 100 times as many cells as people, they should be 100 times more likely to have a cell slip into a cancerous state and cause the disease over their long life span of 50 to 70 years. And yet it's believed that elephants get cancer less often, a theory confirmed in this study. Analysis of a large database of elephant deaths estimates a cancer death rate of less than 5 percent compared to 11 to 25 percent in people.
