Scientists found that sleeping considerably improves our creativity. After taking a nap people are able to think faster and put more imagination into their thinking. Besides, if we dream, the thinking abilities are improved even more.

    Researchers consider that sleeping on a problem in most cases leads to elucidation(解释). They say when a person enters a phase called Rapid Eye Movement (REM) during sleep, it increases the effect. Such phase takes place right before we awake and according to scientists it helps our brain make links between unrelated subjects.

    In the study, led by Professor Sara Mednick, scientists made a conclusion that the REM was "important for assimilating(消化) new information into past experience" in order to find solutions to creative problems.

    Prof. Mednick is a psychiatrist at the University of California. Her study involved the analysis of 77 adults. Each participant was given several word-associated creative tasks. All tasks were given in the morning, with participants being shown a number of groups of 3 words, for example: cookie, heart and sixteen. They were asked to come up with a word that would be associated with all three given terms—like sweet. Sometime later, after some participants were allowed to sleep, they were asked to perform the same tasks and some new ones. It is worth mentioning that while some people slept, researchers used brain scans to see the type of sleep each participant entered.

    When given the same tasks, participants, who took a nap, were able to give more varied solutions, some of which were much better than they gave earlier. But when given new tasks, researchers found that those who entered REM sleep had a 40 percent better result compared to the performance they showed in the morning.

    Do you want to be productive（富有成效的）at work or at home? Here's what you should do.

Turn off television

    I used to tell myself that I needed a break. So, when the kids slept I turned on the cable and watched whatever program that caught my fancy. Often, I found myself not watching, just channel-surfing. And I didn't end up watching a full program. I decided one day to just give up on TV as it made me sleep late and woke up exhausted（疲惫的）.

    If you want to be productive, cut off TV. You are better off reading a book. Without TV, I have managed to finish many books which I have bought but never read.

Limit Internet Use

    The other big distraction that can make you sleep late is the Internet. Probably because you will be checking your emails, updating your blog, watching YouTube, etc. Try limiting the use of it at home, or switch it to the morning session.

    Nowadays, I check all my personal emails early in the morning. When I get into work, I find myself less tempted to check personal emails.

Know Your Priorities(优先考虑的事)

    Really, it is all about the choices you make and the priorities you have. If you know it is competitive out there in the world, how can you be a better worker than the person who is also aiming for the position above you?

Rest Early, Rise Early

    You want to be productive? Rise early, read more books, have more energy, be more focused and set standards for others to catch up. It's as simple as that.

    Dreaming of summer picnics filled with family and fun? We've come up with 4 of the top picnic areas across the US.

    Cumberland Islands, Georgia

    Just a few hours south of Savannah, this national seashore is a picnic paradise. It's an unspoiled place in the Deep South with over 50 miles of hiking trails (小径). Covered in Spanish moss, the trails are lined with trees and since it's still a rural area, the stars line up for a spectacular show at night and create the perfect evening starlit picnic opportunity.

    Grant Park, Chicago

    If you are looking for delicious food in Chicago, go for a taste of a 20-day, lake-front, foodie festival that happens in October each year. Grab a spot near the fountain to enjoy your picnic, appreciate the city scenery and lake views and relax with family and friends. If you are there on July 4^th, be sure to plan the day to include the fireworks display at the Navy Pier.

    Cranberry Islands, Maine

    Here, you'll enjoy natural picnics with island views. The islands are a delightful group of islands about 20 minutes offshore from Acadia National Park. You can visit the islands by private boat or ferry (渡船) service. Bring a picnic basket along for the ride as it's a romantic picnic area to take your special someone or go for a family outing to visit the islands.

    Big Sur, California

    The Point Lobos State Reserve is a small gem. Besides the coastal wildlife there are rare plant communities, and unique geological formations. It's good to have a picnic there. We recommend bringing a telescope, because much of the wildlife can be seen only at a distance.

    Many of us have reached in our pockets, feeling a vibration (振动), wrongly believing our mobile phones have just rung. The phenomenon even has a name: phantom (幻觉的) vibration syndrome—and found it is surprisingly common.

    Now scientists believe that we are so alert (警觉) for phone calls and messages we are misinterpreting slight muscle spasms (痉挛)as proof of a call. Robert Rosenberger, an assistant professor at the Georgia Tech Institute of Technology has studied the delusional calls. He said sufferers describe a vague tingling feeling which they think is their mobile phone indicating it has received a text message or call while on 'silent'. But when the device is retrieved, there was no one on the other end.

    Dr. Rosenberger said he found so many people say, "This happens to me, but I thought I was the only one. I thought I was odd." It seems that the syndrome particularly affects people at the beck and call of mobile phones or pagers. A 2010 study by Michael Rothberg and colleagues found that nearly 70 per cent of doctors at a hospital in Massachusetts suffered phantom vibrations. A more recent study of US college students found the figure was as high as 90 per cent.

    While the odd feeling is widespread, it does not seem to be considered a grave problem. Dr. Rosenberger said: "It's not actually a syndrome in a technical sense. That's just the name that's got stuck to it." He added," Only 2 per cent of people consider it a problem."

    While this phenomenon is widespread, the scientific community has not yet invested much effort in getting to the bottom of why we suffer phantom calls.

    Dr. Rosenberger said: "People are guessing it has something to do with nervous energy. The cognitive(认知的)scientists are talking about brain chemistry, cognitive pathways changing. But it's not like they have brain scans to go on." He said: "We have a phone call in our pocket all the time and it becomes sort of an extension of ourselves. We have this sort of readiness to experience a call. We feel something and we think, OK, that could be a call."

    Whales, like all mammals(哺乳动物),need air, and come to the surface to breathe through a blowhole. A drone(无人机)that floats over the blowholes of humpback whales as they are making annual journey along Australia's east coast is being used by Australian scientists for collecting nasal mucus(鼻腔粘液)of whales.

    Vanessa Pirotta, a biologist at Macquarie University says that nasal mucus indicates the health of the whale. "It is the biological mixture that you see as a whale takes a breath as it surfaces from the water," she said. You can hear sounds of sharp breaths as a whale breathes because, after all, they are animals like you and I. So as they take a breath it is a lot of lung bacteria coming out from their lungs, which we can collect to provide a brief idea of whale health.

    Australian researchers have attached a special dish that is used in scientific tests to a drone which flies through the whale's nasal mist. As a whale comes to take a breath—you can actually see it coming to the surface on really good weather days —the drone then lowers, the dish is then opened, collecting nasal mucus for later research.

    The research could help to solve one of the secrets of another impressive creature of the deep —the Southern right whale. Its numbers have recovered on Australia's west coast since hunting became suppressed but its population on the eastern seaboard remains stubbornly low.

    In the past, studies into whale health had to rely on examining whales that were either killed or those whales that had been trapped on a beach. Drones allow scientists to collect nasal mucus from free-swimming whales to gather information in a safe way.
