    Are you a morning person? You might not like the findings in this new research.

    From a lack of air and drinking water to solar radiation, theoretical Mars pioneers face any number of potential obstacles to settling on the red planet. Now, scientists have found something else to add to the list: seriously messed-up biological clocks.

    One day on Mars - which scientists refer to as the solar day, or “sol”- is 37 minutes longer than a day on Earth. A team of European scientists recently demonstrated why that could be a problem.

    Circadian rhythms are the body's natural cycles of rest and waking, which tend to follow roughly 24-hour light-dark cycles. These natural rhythms - which play a role in biological functions including brain wave activity and hormone production - can be interrupted by things like jet lag(时差)and night shift work.

    For the study, the researchers compared mice with healthy, 24-hour circadian clocks to mice with a genetic change that caused them to have shorter, 20-hour circadian clocks. The mice with healthy biological clocks were more likely to survive and reproduce, while the mice with shorter biological clocks were more likely to die off.

    What does this all have to do with space travel? Since the Martian sol is longer than a day on Earth, people with shorter circadian clocks could suffer from health problems as they try to adapt to the rotational speed of the red planet.

    Unfortunately, the body is unlikely to adapt to the new conditions or “learn” to develop a longer clock. As Loudon explained,“ Learning is not a likely option.”

    In other words: Sorry, super-early risers - NASA might not want you for the next Mars mission.

    Oxford English Dictionary editors recently said that "run" has become the word with the most meanings in English, with more than 645 different usage cases for the verb form alone. This entry(条目), took one professional dictionary writer nine months of research to complete. How could three little letters be responsible   for so many meanings?

    Think about it: When you run a fever, for example, those three letters have a different meaning than when you run a bath to treat it, or when your bathwater runs over and makes your bath runner wet, forcing you to run out to the store and buy a new one. There, you run up a bill of $85 because besides a small carpet and some cold medicine, you also need some thread to fix the run in your stockings and some tissue for your runny nose and a carton of milk because you've run through your supply at home, and all this makes fear run through your soul because your value club membership runs out at the end of the month and you've already run over your budget on last week's grocery run when you ran over a nail and now your car won't even run properly. God—you'd do things differently if you ran the world.

    When the OED's first edition came out in 1928, the longest entry belonged to another three letter word: "set". Today, it has some 200 meanings.

    Why is "run" suddenly the Swiss Army Knife of verbs? According to British author Simon Winchester, "run" has earned some major lift during the Industrial Revolution (工业革命), when new inventions chose it as their verb of choice. "Machines run, clocks run, computers run there are all of those that began in the middle of the 19th century," Winchester says.

    So, ready to run through the whole list of definitions(定义)? You'll have to wait for the next edition of the OED, expected in 2037.

    Email has brought the art of letter writing back to life, but some experts think the resulting spread of bad English does more harm than good.

    Email is a form of communication that is changing, for the worse, the way we write and use language, say some communication researchers. It is also changing the way we interact(交流) and build relationship. These are a few of recently recognized features of email, say experts, that should cause individual and organizations to rethink the way they use email.

    "Email has increased the spread of careless writing habits, "says Naomi Baron, a professor of linguistics at American University. She says the poor spelling, grammar, punctuation(标点符号) and sentence structure of emails reflect a growing unconcern to the way we write.

    Baron argues that we should not forgive and forget the poor writing often shown in emails. "The more we use email and its tasteless writing, the more it becomes the normal way of writing," the professor says.

    Others say that despite its poor prose(文字), email has finished what several generations of English teachers couldn't: it has made writing fashionable again.

    "Email is a critical new communication technology," says Ian Lancashire, a University of Toronto professor of English." It fills the gap between spoken language and the formal methods of writing that existed before email. It is the purest form of written speech."

    Lancashire says email has the mysterious ability to get people who are scared by writing to get their thoughts flowing easily onto a blank screen. He says this is because of email's close similarity to speech." It's like a circle of four or five people around a campfire," he says.

    Still, he accepts that this new found freedom to express themselves often gets people into trouble. "Almost everyday I get emails that apologies of previous emails," he reports.

    In the US, the number of emails sent in a day exceeds(超过) the number of letters mailed in a year. But more people are recognizing the content of a typical email message is not often exact.

    With a focus now on the environmental influence over the fashion industry, some bloggers who cut their teeth sharing details of endless clothes and products are changing their direction-enter the "no-buy" movement. The idea is simple: instead of buying new clothes or beauty products, you make a promise to use the things you already own. Some people sign up to a "no-buy year". Others decide not to buy for a few weeks or months or choose "low-buy" with a strict spending cap.

    This life style has caught the attention of many people who struggle to keep up with the latest fashion. Modern people's desire for material things is often not caused by poverty (贫穷) , but by anxiety, which is further enlarged by the rise of social media.

     "Social media puts pressure on people to spend money," says Katherine Ormerod, author of Why Social Media is Ruining Your Life. Many online influencers are given the items they use and wear for free, but Ormerod is determined not to wear any new products she is given. "Really I just want to convince people they don't have to spend a lot of money on fashion to look stylish and there's no such thing as 'last season' anymore," she says. "True style has never been about that anyway."

    However, self-satisfied expressions of minimalist (极简主义的) living have earned plenty of doubts. "Minimalism is a good quality only when it's a choice, and it's telling that its fan base is from the well-off middle class. To people who don't have enough in the first place, celebrations of 'less is more' can sound more like a luxury (奢侈) than a considerable loss." Stephanie Land wrote in The New York Times.

Students who are better able to understand and manage their emotions effectively, a skill known as emotional intelligence (EI), do better at school than their less-skilled classmates, according to research published by the American Psychological Association.

"It's not enough to be smart and hardworking. Students must also be able to understand and manage their emotions to succeed at school," said Carolyn MacCann, lead author of the study. MacCann and her colleagues analyzed data from more than 160 studies, representing more than 42,000 students from 27 countries, published between 1998 and 2019. The students ranged in age from primary school to college. The researchers found that students with higher EI tended to get higher grades and better achievement test scores than those with lower EI scores. This finding held true even when controlling for intelligence and personality factors. What was most surprising to the researchers was the association held despite different ages.

As for why EI can affect academic performance, MacCann believes a number of factors may come into play. "Students with higher EI may be better able to manage negative emotions, such as anxiety, boredom and disappointment, which can negatively affect academic performance," she said. "Also, these students may be better able to manage the social world around them, forming better relationships with teachers, classmates and family, all of which are important to academic success." Finally, the skills required for EI, such as understanding human motivation and emotion, may overlap with (与……重叠) the skills required to master certain subjects, such as history and language, giving students an advantage in those subject areas, according to Mac Cann.

However, Mac Cann cautions against widespread testing of students to identify and target those with low EI as it may stigmatize (给……打上烙印) those students. Instead, she recommends interventions that involve the whole school, including additional teacher training and a focus on teacher well-being and emotional skills. "Programs that integrate emotional skill development into the existing curriculum would be beneficial, as research suggests that training works better when run by teachers rather than external professionals," she said. "Increasing skills for everyone not just those with low EI would benefit everyone."
