“Beating is a sign of affection, cursing (骂)is a sign of love.” Many may not expect to hear the words of the old Chinese saying in these modern times—with parents wealthier and better educated than they have ever been—but experts say they still ring true.

    Today, it seems, Chinese parents are more likely to send their children to pre­college military academies in the United States in the hope that some tough love will pave the way to success.

    “Good education doesn't mean letting your children enjoy privileges, especially our boys.” said Song Wenming, an entrepreneur (企业家)in Jinhua' East China's Zhejiang province. “They should be raised in tough conditions to know what to fight for in the future.”

    In August, Song sent his 17­year­old son to Valley Forge Military Academy (VFMA) in Pennsylvania. And he is far from alone, even though it takes a lot of money—around $48,000 per year—to send a child to a strict military school.

    Statistics show that an increasing number of Chinese students have been registering with such academies .

    A few years ago, there were no Chinese students at Valley Forge. Today, there are 28.“All of the Chinese students at Valley Forge came from wealthy families; some of them were spoiled.” said Jennifer Myers, director of marketing and communications at the school.

    Song's only son, Song Siyu, had a rocky start during his first six weeks at the school. The teenager said he went to the school voluntarily but did not expect it to be as difficult.

    Now, three months later, he has perfected the art of taking a bath in 35 seconds, finishing a meal without looking at his food, and making his bed with precision. He can even take criticism, no matter how unreasonable.

    “The training is hard but I know it is good for self­development of individuals.” said Song Siyu. “The endless training and scolding are just ways to build up our character; they are not personal .”But his enthusiasm is not universal. Ten of the 13 Chinese students who joined the academy this year have transferred to other schools. But for those who stick with it, there is a reward for all the hard work.

    Developed by researchers and designers specializing in typography(印刷术)and behavioral science, Sans Forgetica is a new font(字体)designed to help readers better remember the information they read by forcing them to spend a bit more time on each word.

    The design of Sans Forgetica is based on a font called Albion, but with substantial  modifications(修改)to reduce familiarity and attain its goal of engaging the brain more and helping the reader retain(保留) more information. It was developed by scientists at RMIT University in Melbourne, Australia, who believe it could help students studying for exams.

    “We believe this is the first time that specific principles of design theory have been combined with specific principles of psychology theory in order to create a font, ”Behavioral economist Jo Peryman told DW.

    If fonts are too familiar, readers often glance over them without their brain creating may  memories of what was read. At the same time, if a font is too outlandish, the brain has to struggle too much to decipher(破译)it while neglecting the retention of information. According to its developers, “Sans Forgetica lies at a sweet spot where just enough obstacle has been added to create that memory retention.” Its modifications force readers to spend more time, but not too much time, reading each word, allowing the brain to engage in deeper cognitive processing.

    So does Sans Forgetica actually work? Does it help readers better remember the information they read? So far, studies have shown that it can make a difference, although not a significant one.

    One experiment had 96 participants recall word pairs presented in three different fonts. They remembered 69 percent of the word pairs written in Sans Forgetica, compared to 61 percent for the other fonts. In a different experiment, 303 students took a mock(模拟)multiple-choice exam, and whenever the text was presented in Sans Forgetica, they remembered 57 percent of the text, compared to only 50 percent of the surrounding text written in Arial font.

    So Sans Forgetica won't give you the memory of an elephant, but if you're the kind of person who believes every little bit helps, it might be worth a try.

    As people age, the body changes in all sorts of predictable ways. Brains can slow. Wounds take longer to recover. And sleep patterns(模式) shift, too. This can come as news to many, says Michael V. Vitiello, a psychologist at the University of Washington who is expert in sleep in aging.

The most noticeable—and often most annoying—changes are how sleep and wake-up times change and sleep gets lighter, often beginning in middle age. Gone are weekend sleep to 11 a.m. and the ability to sleep through a noisy garbage truck down the block.

But not every restless night can be ignored. Studies have found that poor sleep can create a particular threat to older adults—Falls, depression and anxiety, problems with memory, and increased suicide(自杀) risk are among the effects of sleep issues in this population group that researchers have found. But scientists are still unsure why those risk connections exist.

    What is clear is the connection between good sleep and psychological well-being in older adults. A 2010 study showed us that connection when it came to sleep quality, but sleep quantity didn't show the same effects. And that, experts say, may be the key to understanding sleep as you age. If you're sleeping less, but don't feel negative effects out of bed, the changes you notice may just be normal age-related.

    Over time, Vitiello says, sleep patterns simply change. "A lot of older adults recognize that they don't sleep the same as they did when they were 18, but they can still function and they're OK. And all is well with the universe."

    Moving in with a boyfriend causes women to eat more unhealthily and put on weight. But the opposite is true for men, whose long-term health benefits when they move in with a female partner.

    Dieticians at Newcastle University said both partners try to please one another, and so change their dietary habits to suit their other half.

    It leads men to eat more light meals, such as salads, fruit and vegetables, while women choose to make creamier, heavier dishes curry or rich pasta sauces, which may please their partner. Women still have the strongest long-term influence over the couple's diet and lifestyle, as they still have the traditional role of shopper and cook in most households.

    The report, by Newcastle University's Human Nutrition Research Centre, reviewed the finding of a variety of research projects from the UK, North America and Australia, which looked at the eating and lifestyle habits of couples.

    The research shows that women are more likely to put on weight and increase their consumption of foods high in fat and sugar when they move in with their partner

    Women also use food as a comfort when dealing with emotional stress and have been found to gain weight when a relationship ends, while the same finding has not been observed in men.

    Many couples reported food as being central to their partnership, and eating together in the evening was particularly important to many.

    Report author and registered dietician Dr. Amelia Lake said, "The research has shown that your partner is a strong influence on lifestyle and people who are trying to live healthier lives should take this factor into consideration."

    Just ask any new parent: Adding a baby to a household can also add stress to a career. Now, a new study backs that up with some astonishing numbers: After science, technology, engineering, and mathematics(STEM)professionals become parents, 43%of women and 23% of men switch fields, transition(转变)to part-time work, or leave the workforce entirely.

    Many researchers and parents already knew that STEM can be unwelcoming to parents, particularly mothers. But" the considerable departure was astonishing, "says Erin Cech, an assistant professor of sociology at the University of Michigan in Ann Arbor and lead author of the study, published in the Proceedings of the National Academy of Sciences. For both genders, "the proportions were higher than we expected."

    The surprisingly high reduction rate for men also highlights that" parenthood in STEM is not just a mothers' issue; it's a worker issue, "Cech says. She hopes that the findings" might motivate changes, "such as more paid parental leave from both government and employers and policies that better support flexible work time without a tight routine. "We are not suggesting that people who want families should avoid STEM; that's not the solution," she emphasizes.

    By 2018, 78% of new fathers were still working in STEM, the vast majority full time. For new mothers, 68% were still in STEM, but only 57% worked full time. For professionals without children, on the other hand, 84% of men and 76% of women were predicted to still be working in STEM full time in 2018. For the new parents across all fields, 16% of women were working part-time and 15% had left the workforce, as compared with just 2% and 3%, respectively, for men. These sharp differences make clear that, even though the reduction rate for fathers is higher than expected, mothers still face particular career challenges.

For centuries Antarctica has attracted people from around the world. Explorers sought to travel there. Scientists have studied weather, wildlife, and geology there for decades. {#blank#}1{#/blank#} In the last few decades, though, scientists have reported that the ice is melting.

 {#blank#}2{#/blank#} That's a difficult question to answer. The loss of ice in Antarctica has not been linear (直线的). That means it isn't a steady decrease. In fact, the rate of melting can vary greatly from year to year. Still, scientists warn that the continent's ice sheet is shrinking.

{#blank#}3{#/blank#} Climate change is warming the world's oceans and affecting the currents (洋流) of the Earth's oceans. These currents are bringing more warm water to Antarctica than ever recorded.

Today, the planet is warming at a rate that alarms scientists. {#blank#}4{#/blank#} The effects of such a rise could cause major problems. It will increase flooding, especially in areas near shores. A large rise in sea level could even make some regions uninhabitable. This could cause millions around the world to become climate refugees (难民).

Can humans stop Antarctica from melting? Probably not — but experts do believe people can slow the process. How can you help? Pay attention to your carbon footprint. {#blank#}5{#/blank#} Only changes on a large, global scale (范围) can truly make a difference to Antarctica.
