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.

    When it comes to car hiring,all car hire companies require that you should have a full driving license for at least one year,some of whom may ask for two years,especially for younger drivers.

    Most car hire companies will not automatically hire out a car to someone under the age of 25 or to people over 70. But there are exceptions. Some listed companies are normally prepared to serve people of 21 and over. And some may go over the age limit and provide service for older people( aged 70 and over) providing you have no record of breaking the law and valid license, and a doctor's letter of good health.

    Now read on for some information about national companies with many bases hiring out cars to people aged 21 and older drivers.

Creation,or Evolution

    Were humans created,or did they evolve（进化）?How old is the Earth?The debate between science and religion continues to be heated.In Creation or Evolution,Michael Ebifegha examines these two opposed world views within the structure of empirical（实证的）science.

    Inspired by a 9-year-old cyclist, Lauren Turner, who can only use one hand, a group of University of Guelph students has won an international award for their invention－a bike brake lever (刹车手柄) that pulls both the front brake and the back brake at the same time.

    Lauren Tuner was able to ride her bike, but not as confidently and quickly as her friends.

    “She couldn't use the front brake. She only used the back brake, but the front brake makes you stop twice as fast,” says Micha Wallace, who, with Katie Bell, Anina Sakaguchi and Andrew Morries won second prize in the James Dyson Award for their single-handed bike brake lever.

    "Lauren Turner tried the device (装置) first and she used it all last summer. She had no problems. It helped her go faster because she felt more confident in her braking abilities. She felt safer." says Wallace.

    The invention was the fourth-year design project for the four students. They designed, tested and created a prototype (模型) within a four-month period.

    When Wallace heard about the James Dyson Award on the news, she and her co-inventors entered their project in the U.K.-based contest, which rewards students designers who create products that improve the way we live. The students collected the runner-up prize－£2,000 for them and £500 for their school.

    As well, they had a chance to meet James Dyson, a U.K. famous inventor. Praising the students for their invention, Dyson says the single-handed brake lever could improve safety for all cyclists. By using both brakes at once, you could prevent the possibility of flying over the handlebars and ending up with an injury.

    The students hope to sell it to a major company. It may be used in other devices that require two hands for operation.

    A population of the world's most aggressive mosquito species was almost completely wiped out by an experiment on two islands in the southern Chinese province of Guangdong, according to a study published.

    The experiment successfully reduced the female Asian Tiger Mosquito population — the main source of bites and disease spread — by up to 94%, reducing the number of reported human bites by 97%.

    One of the Chinese study's researchers, Xi Zhiyong, a professor at Michigan State University, has been a longtime pioneer in this field of study. Running a mosquito factory in southern China, he previously attempted to use sterilized male mosquitoes to mate with unaltered females which developed normally. In the new study, published by the International Journal of Science, Xi and his colleagues attempted to cut mosquito numbers even further by limiting both males and females' ability to reproduce. The results were so successful that they nearly killed the entire female mosquito population on the two islands.

    It isn't the first attempt by researchers to reduce mosquito populations across the world. In 2018, scientists from the Imperial College of London used gene-editing tools to make female mosquitoes sterile, while males developed normally and continued spreading the genetic mutation (突变).Experts said the Asian Tiger Mosquitoes are particularly hard to kill using traditional population control methods, such as pesticides (杀虫剂) and removing stagnant (不流动的) water where the insects lay their eggs.

    Mosquitoes create grave threats to human health beyond just bites. The World Health Organization (WHO) has described the insects as "one of the deadliest animals in the world," due to their ability to rapidly spread deadly diseases such as dengue fever and malaria. There is currently no effective vaccine or treatment for most mosquito-spread diseases, leaving controlling the insects' populations one of the most effective control methods, according to the International Journal of Science. “A new tool like what's being described in this paper is very much needed” said Stephen Dobson, a professor of medical insectology at University of Kentucky.

In 1999, John Smith, a high-school teacher decided it was time to retire. Together with his wife Helen, he set off on a journey around Australia. But when they returned, John found he missed the classroom, so he spent another eight years doing casual teaching.

Then he heard about a program known as Volunteers for Isolated Students' Education (VISE), which pairs up energetic people with educational experience, usually retired teachers, with children whose schooling is largely done remotely, because they live too far away from towns and cities to attend regular schools. John grew up in the country and as a kid in the bush, he always dreamed of running with circus, but he didn't even have much chance to see the circus in person. Therefore he was immediately interested in the program and got a travelling post as a teacher with Stardust Circus.

The lesson timetable was built around the kid's performance schedules. "The eight-year-old I tutored was an awesome gymnast who was part of the teeterboard(跷跷板) act," he explains. "A big guy would jump on the other side, he would swing up in the air, do a couple of twirls(旋转) and land on his uncle's shoulders, and his uncle was standing on the boy's father's shoulders!"

The circus still includes some animal acts, including lions, monkeys, horses, goats and pigs. John and his wife Helen found it extraordinary enough to sink into sleep to the sound of lions roaring, but one day the lion-trainer, Matt, gave him a very special privilege,inviting him in to meet four 13-month old lions in person. While it was understandably a little scary at first, for John it was a never-to-be-forgotten experience, which helped him realize his boyhood dream in ms 75th year.
