Want to add some hours to your day? Ok,you probably can't change the fabric of time. But a new study suggests that theway you feel about your goal can change your concept of time and that somesimple strategies could make you feel less rushed.

In a series of experiments, JordanEtkin, a professor of marketing at Duke, and her co-authors, LoannisEvangelidis and Jennifer Aaker, looked at what happens when people see theirgoals as conflicting with one another. In one, they asked some participants tolist two of their goals that they felt were in conflict, and others simply tolist two of their goals. Those who were forced to think about conflicting aimsfelt more time pressure than those who weren't. In another experiment, the researchersgave participants a similar prompt regarding goal conflict, but this timemeasured their anxiety levels as well as their attitudes toward time. Theyfound that participants who thought about conflicting goals had more anxietythan those who didn't, and that this, in turn, led to feelings of being shorton time.

"Stress and anxiety and timepressure are closely linked concepts," D. Etkin explained. "When wefeel more stress and anxiety in relation to our personal goals, that manifestsas a sense of having less time."

Technological advances that allow peopleto do lots of things at once may increase the fe'eling of goal conflict, shesaid."I think the easier it is for us to try to deal with a lot of thesethings at the same time," She said"the more opportunity there is for us to feel this conflictbetween our goals."She isn't the first to suggest that actual busynessisn't the only thing that can make us feel busy At the Atlantic, Derek Thompson wrote that "as a country, we'reworking less than we did in the 1960s and 1980s." He offered a number ofpossible reasons some Americans still feel so overworked, including "thefluidness ffl±) of work and leisure." As he put it:"The idea thatwork begins and ends at the office is wrong. On the one hand, flexibility isnice, On the other, mixing work and leisure together creates an always-onexpectation that makes it hard for white-collar workers to escape the shadow ofwork responsibilities."

And Brigid Schulte writes in her 2014book Overwhelmed: How to Work, Love, and Play When No One Has the Time thatsome researchers believe "time has no sharp edges. What often matters morethan the activity we're doing at a moment in time, they have found, is how wefeel about it.Our concept of time is indeed,our reality.”

Fortunately, Dr. Etkin and her team didfind ways of making us feel better about time—or, at least, of reducing thenegative influence of goal conflict. When participants performed a breathingexercise that reduced their anxiety, the impact of such conflict on theirperception of time was less pronounced. Reframing anxiety as excitement (byreading the phrase "I am excited!" aloud several times) had a similareffect.

Breathing and reframing may not solveeveryone's time problems—Ms. Schulte writes that some Americans are indeedworking more than they used to. She cites the work of the sociologists MichaelHout and Caroline Hanley, who have "found that working parents combinedput in 13 more hours a week on the job in 2000 than they did in 1970. That's676 hours of additionally paid work a year for a family. And that's on top ofall the unpaid hours spent caring for children and keeping the housetogether." Sometimes, we may feel short on time because we actually are.However, Dr. Etkin believes her findings suggest we may "have the abilityto influence our experience of time more than we think we do."

"We're all going to have times inour lives when our goals seem to be in more conflict than others," shesaid. But with techniques like the ones her team tested, "we really canhelp ourselves feel like we have more time."

    It was in October. I was aimlessly wandering down the street, heading into a most gloriously beautiful sunset. I had an urge to speak to someone on the street to share that beauty, but it seemed everyone was in a hurry.

    I took the next-best action. Quickly I ducked into a department store and asked the lady behind the counter if she could come outside for just a minute. She looked at me as though I were from some other planet. She hesitated, and then seemingly against her better judgment, she moved toward the door.

    When she got outside I said to her, “Just look at that sunset! Nobody out here was looking at it and I just had to share it with someone.”

    For a few seconds we just looked. Then I said, “God is in his heaven and all is right with the world.” I thanked her for coming out to see it; she went back inside and I left. It felt good to share the beauty.

    Four years later my situation changed greatly. I came to the end of a twenty-year marriage. I was alone and on my own for the first time in my life. I lived in a trailer park which, at the time, I considered a real come-down, and I had to do my wash in the community laundry room.

    One day, while my clothes were going around, I picked up a magazine and read an article about a woman who had been in similar circumstances. She had come to the end of a marriage, moved to a strange community, and the only job she could find was one she disliked: clothing sales in a department store.

    Then something that happened to her changed everything. She said a woman came into her department store and asked her to step outside to look at a sunset. The stranger had said, “God is in his heaven and all is right with the world,” and she had realized the truth in that statement. From that moment on, she turned her life around.

    Ask any kid, and you'll likely hear that time spent with friends is the coolest and most important part of the school day. Educators, as well, acknowledge that making friends is one of the most valuable things children do as they learn and grow. But many parents are perplexed by their children's social lives, wondering how to help their kids cope with the challenges, heartbreaks, and the joys of making friends, losing them, and making friends again.

    “Friendships help children gradually learn to be independent, contributing members of a community and it's just as important as their academic growth” notes Diane Levin, Ph.D., author of “Remote Control Childhood.” However, it's a slow process. There are many social skills to learn, which advance with age and experience, trial and error, and experiencing the satisfaction that comes from contributing to an ongoing friendship.”

    “Friendship starts as soon as children can crawl off their parents' laps over to another child,” adds Michael Thompson, Ph.D., co-author of her life with you to her life with her friends. but who their friends are, how they interact with them, and how popular they are, is something parents have only limited control over.”

    Experts on children's behavior say that problems like jealousies, breakups, bullying and teasing account for a big part of what parents, kids and teachers talk about, and what parents worry about.

    Get insights into how children's friendships develop and how parents can help, if needed, and find ways to determine if your child is at risk for serious social problems or simply suffering from real (but common) social challenges.

    The world's first-known nursery for baby giant manta rays(蝠鲼) has been discovered hidden away in the Gulf of Mexico, the place of 70 miles off the coast of Texas, after studying decades of giant manta ray data from the area by the scientists.

    Where the baby manta rays grow up has long troubled scientists, as they are rarely spotted in the four to five years it takes them to become adults, when they can often grow to more than 20ft wide.

In the study Mr Stewart and colleagues describe a reef (暗礁)—filled with mantas of all ages—where the sea floor runs down into deeper water. He said "We think they may be feeding on specific types of zooplankton(浮游生物) there, then migrating up toward the surface, where we saw them. They might be hanging around the banks because it could be a little safer than open water. We've seen them so rarely that we know very little about these baby manta rays. We don't know how far they move, or exactly what they feed on, or all of the habitats these access.”

    Giant manta rays are listed as species dying out by protectors, although actual population numbers of the mysterious "gentle giant" are hard to calculate. Sightings of the closely-related reef manta, however, have dropped by 90 percent in regions of southeast Asia in the past decade, according to a study.

    Fishing is considered the biggest threat to giant manta numbers, both intentional and accidental. Their gill plates(腮下肉)- the parts through which they filter(过滤) their food from seawater-are sold in China for medical purposes, while they often end up as something caught by mistake due to their huge wings.

    The fridge is considered necessary. It has been so since the 1960s when packaged food list appeared with the label: "Store in the refrigerator."

    In my fridge less Fifties childhood, I was fed well and healthy. The milkman came every day, the grocer, the butcher, the baker, and the ice-cream man delivered two or three times each w eek. The Sunday meat would last until Wednesday and the bread and milk left became all kinds of cakes. Nothing was wasted, and w e w ere never troubled by rotten food. Thirty years on, food deliveries have stopped, and fresh vegetables are almost impossible to get in the country.

    The invention of the fridge contributed comparatively little to the art of food preservation. Many well-tried techniques already existed — natural cooling, drying, smoking, salting, sugaring, bottling...

    What refrigeration did promote was marketing — marketing hardware and electricity, marketing soft drinks, marketing dead bodies of animals around the world in search of a good price.

    Consequently, most of the world's fridges are to be found, not in the tropics where they might prove useful, but in the rich countries with mild temperatures where they are climatically almost unnecessary. Every winter, millions of fridges hum (make a low continuous sound) away continuously, and at vast expense, busily maintaining an artificially-cooled space inside an artificially-heated house —while outside, nature provides the desired temperature free of charge.

    The fridge's effect upon the environment has been clear, while its contribution to human happiness has been unimportant. If you don't believe me, try it yourself, invest in a food cupboard and turn off your fridge next winter. You may miss the hamburgers, but at least you'll get rid of that terrible hum.

    Your teenage best friend could be good for your long-term mental health, according to a new study published in the journal Child Development According to the findings, teenagers aged 15 to 16 who had a close friendship rather than a larger group of friends they were less close to had a greater sense of self-worth by the time they were 25 years old. Those people with a very close best friend were also less likely to experience depression and social anxiety, the study found.

    "Close friendship strength in mid-adolescence predicted relative increases in self-worth and decreases in anxiety and depressive symptoms by early adulthood, "the authors, led by Rachel K, Narr, a postdoctoral student focused on clinical psychology at the University of Virginia, wrote.

    A past research has suggested that adolescent friendships are important. Friendships during the teenage years predict academic success and improved mental health. But the new research further explores the type of friendships teenagers have. "My hunch(预感)was that close friendships compared to broader friendship groups and popularity may not function the same way," Narr told Quartz. "Being successful in one is not the same as being successful in the other."

    Many study participants did not continue to have a close relationship with their high-school best friend, leading the researchers to wonder what exactly was responsible for the mental health benefits. They suspected that the skills and ability to build such a friendship may be more important than the friendship itself.

    And as the researchers point out, those skills are not necessarily brought to bear in the world of social media. "As technology makes it increasingly easy to build a social network of shallow friends, focusing time and attention on developing close connections with a few individuals should be a priority," study co-author Joseph Allen said in a statement.
