We all have dreams sometimes. Some are sweet but some are nightmares. Almost all researchers in sleep explain that nightmares are a reaction to negative experiences that happen during waking hours. However, some of them believe that nightmares do have some real benefits. One 2017 study, for example, found that frequent nightmare sufferers rated themselves as more empathetic（共鸣的）.They also displayed more of a tendency to unconsciously mirror other people through things like yawning. People who have constant nightmares also tend to think further outside the box on psychoanalysis tasks. Some other researchers have found support for the idea that nightmares might be linked to creativity.

    People seeking cure for nightmares were not necessarily more fearful or anxious, but rather had a general sensitivity to all emotional experience. Sensitivity is the driving force behind intense dreams. Heightened sensitivity to threats or fear during the day results in bad dreams and nightmares, whereas heightened passion or excitement may result in more intense positive dreams. And both these forms of dreams may feed back into waking life, perhaps increasing suffering after nightmares, or promoting social bonds and empathy after positive dreams.

    The effects go further still. This sensitivity overflows over into perceptions and thoughts: people who have a lot of nightmares experience a dreamlike quality to their waking thoughts. And this kind of thinking seems to give them a creative edge. For instance, studies show that such people tend to have greater creative talent and artistic expression. And people who often have nightmares also tend to have more positive dreams than the average person.

    The evidence points towards the idea that, rather than disturbing normal activity, people who are unfortunate in having a lot of nightmares also have a dreaming life that is at least as creative, positive and vivid as it can be distressing and terrifying. What's more, this imaginative richness is unlikely to be limited to sleep, but also is filled with waking thought and daydreams. Even after people wake up and shake off the nightmare, in other words, a mark of it stays behind, possessing them throughout the day.

    Going to university is supposed to be a mind-broadening experience.

    That assumption is possibly made in contrast to training for work straight after school. But is it actually true? Jessika Golle of the University of Tubingen, Germany, thought she would try to find out.

    Her result, however, is not quite what might be expected. It shows that those who have been to university do indeed seem to leave with broader and more inquiring minds than those who have spent their immediate post-school years in vocational training for work. However, it is not the case that university broadens minds. Rather, work seems to narrow them.

    After studying the early career of 2095 German youngsters, Dr. Golle reached the conclusion.

    During the period under investigation, Germany had three tracks in its schools: a low one for pupils who would most probably leave school early and enter vocational training; a high one for those almost certain to enter university; and an intermediate one, from which there was a choice between the academic and vocational routes.

    The team used two standardized tests to assess their volunteers. One was of personality traits and the other of attitudes. They administered both tests twice once towards the end of each volunteer's time at school, and then again six years later.

    Of the original group, 382 were on the intermediate track, and it was on these that the researchers focused. Of them, 212 went to university and the remaining 170 chosen for vocational training and a job.

    When it came to the second round of tests, Dr Golle found that the personalities of those who had gone to university had not apparently changed. Those who had undergone vocational training and then got jobs were not that much changed in personality, either except in one crucial respect they had become more responsible.

    That sounds like a good thing, compared with the common public image of undergraduates as a bunch of pampered layabouts(娇生惯养的闲人). But changes in attitude the researchers recorded were more worrying. In the university group, again, none were detectable. But those who had chosen the vocational route showed marked drops in interest in tasks that are investigative and enterprising in nature.

    And that might restrict their choice of careers. Some investigative and enterprising jobs, such as scientific research, are, indeed off limits to the degreeless.

    But many, particularly in Germany, with its tradition of vocational training, are not. The researchers mention, for example, computer programmers, finance-sector workers and entrepreneurs as careers requiring these attributes.

    If Dr Golle is correct, and changes in attitude brought about by the very training Germany prides itself on are narrowing people's choices, that is indeed a matter of concern.

    People can't see you when you're speaking on the phone, but they can hear you. So, the way you speak is especially important. In fact, researchers have calculated that 80% of communication over the phone is through your tone of voice; and only 20% is from the words you use. Here are our top tips on how to speak over the phone.

    ①Facial Expressions

    Your facial expression can influence your voice. For example, if you smile, your voice will sound warm and friendly, just the opposite, if you have an angry look on your face, it can make you sound unpleasant.

    ②Volume

    If you speak too loudly, you could sound angry. And if you speak too softly, it'll be difficult to hear you. So, speak loudly enough to be heard clearly, but not so loud that you're shouting.

    ③Pace

    The pace of your voice is how quickly you speak. And this can show how you feel. For example, an angry person might speak faster than normal. Or a downhearted person might speak very slowly. Try speaking a little more slowly than normal. This will make you sound confident, and it'll make it easier for the other person to understand you.

    ④Gestures

    Gesturing can influence the tone of your voice. When you gesture, you bring more air into the lungs, which can make your voice sound warmer. Gestures are also useful to help you stress the right words or even find the words you need. The best thing about gesturing during a phone call is that no one can see what you're doing, so you can gesture as wildly as you like!

    ⑤Movement

    If you're feeling nervous, stand up and move around. It will reduce the nervousness in your body and help your voice to sound more confident.

    ⑥Pauses (停顿)

    Using pauses every now and then can help you to slow down. This will make you sound more confident and in control. Also, if you pause after giving some new information, it'll give the other person time to understand it. At the same time, listen to how the other person uses pauses. They could tell you something about the speaker's feeling. For example, when a speaker is really angry, he might use pauses and says, "I…am…so…angry…"

Most children love stories. Stories are entertaining and fun, but can they be more than just fun? Findings from a new study led by Rebecca de Leeuw, an assistant professor at the Radboud University, indicate stories in movies can also be meaningful for children. 

The researchers contacted children between 4 and 15years old after they watched the Disney film Inside Out. This film takes place mainly in the head of an 11-year-old girl, where her emotions—Joy, Sadness, Anger, Fear and Disgust, personified as different characters—conflict on how to help her best in her new life after her family moves. The story follows the "hero's journey" —a classical narrative（叙事的）framework, which involves a hero who goes on an adventure, overcomes challenges, and return s changed. So the research team chose this film. When making this film, the film-makers had in-depth discussions with psychologists to make the emotion animation consistent with scientific knowledge. 

The research team asked mostly open-ended questions to encourage the children to share their thoughts, including the key question: "Was there a part of the movie you had to think about?" Children looked at stills of important scenes and were invited to explain in their own words what happened. If they liked, they also rewatched scenes of the film. 

While watching, children made sense of the feelings, motives and behavior of characters in the film, using their social intelligence skills. They also further developed these skills when they were challenged in making sense of the story. Children also mentioned they appreciated seeing acts of pity, kindness, love and bravery in the film. Just like adults, they were even touched to tears by these qualities. 

One of the children in the study even expressed that Joy inspired her to never quit in her own life. The more insights children gained while watching, the more meaningful the story became for them. Altogether, stories in movies can be a quick way for children to gain life experience and wisdom. 

The Ebola virus is an infectious disease that for years had almost no treatments, and it kill s about half the people it infects. Now a new study published in The Lancet Infectious Diseases shows that a promising vaccine （疫苗）, named rVSV△G-ZEBOV-GP, doesn't just help to reduce infections, it also can cut those death numbers in half.

The vaccine is a single-dose （单剂） muscular one that causes cells to produce one of the virus's proteins. "Later, if the person is exposed to Ebola,"explains Rebecca Coulborn, a scientist with Epicentre, the medical research arm of Doctors Without Borders, "their immune system will recognize the viral protein. This recognition allows the immune system to be prepared to attack the virus and protect the person from Ebola virus disease."

Researchers showed rVSV△G-ZEBOV-GP was effective at reducing the risk of infection, but no one knew how capable it was of preventing death in someone who was vaccinated after becoming infected during an epidemic （流行病）. To figure it out, Coulborn and her colleagues focused their efforts on the second-largest Ebola outbreak ever recorded, which occurred in the Democratic Republic of Congo between 2018 and 2020.

"Every single Ebola health facility across the entire Ebola epidemic had a standardized list of all admissions," says Coulborn. This list included 2,279 confirmed Ebola patients, and it recorded whether or not each person had been vaccinated before they got sick—and if so, when they'd received the vaccine.

Coulborn found the death rate was 56% among the unvaccinated. But for those who'd received the vaccine, that rate was cut in half. This was true no matter when someone got vaccinated before the appearance of symptoms. Additionally, those who'd been vaccinated had less virus circulating in their bodies than those who hadn't. So the vaccine played an important role.

Rebecca Coulborn says she feels buoyed by the results—since they offer clear evidence that people who're at risk of contracting Ebola should be vaccinated early. It's an opportunity to cut chains of transmission （传播） and prevent an outbreak before it gains speed.
