Have you ever found yourself in his situation: You hear a song you used to sing when you were a child-a bit of nostalgia(怀旧) or “blast from the past,” as we say. But it is not a distant childhood memory. The words come back to you as clearly as when you sang them all those years ago.

    Researchers at the University of Edinburgh studied the relationship between music and remembering a foreign language. They found that remembering words in a song was the best way to remember even one of the most difficult languages.

    Here is what they did. Researchers took 60 adults and randomly divided them into three groups of 20. Then they gave the groups three different types of “listen-and-repeat” learning conditions. Researchers had one group simply speak the words. They had the second group speak the words to a rhythm, or beat. And they asked the third group to sing the words.

    All three groups studied words from the Hungarian language for 15 minutes. Then they took part in a series of language tests to see what they remembered.

    Why Hungarian, you ask? Researchers said they chose Hungarian because not many people know the language. It does not share any roots with Germanic or Romance languages, such as Italian or Spanish. After the tests were over, the singers came out on top. The people who learned these new Hungarian words by singing them showed a higher overall performance. They did the best in four out of five of the tests. They also performed two times better than those who simply learned the words by speaking them.

    Dr. Katie Overy says singing could lead to new ways to learn a foreign language. The brain likes to remember things when they are contained in a catchy 3, or memorable 4, tune 5.

    Dr. Ludke said the findings could help those who struggle to learn foreign languages. On the University of Edinburgh's website Dr. Ludke writes, “This study provides the first experimental evidence that a listen-and-repeat singing method can support foreign language learning, and opens the door for future research in this area.”

A warm drink of milk before bed has long been the best choice for those wanting a good night's sleep. But now a study has found it really does help people nod off—if it is milked from a cow at night.

    Researchers have discovered that “night milk” contains more melatonin(褪黑激素), which has been proven to help people feel sleepy and reduce anxiety.

    The study, by researchers from Seoul, South Korea, involved mice being fed with dried milk powder made from cows milked both during the day and at night.

    Those given night milk, which contained 10 times the amount of melatonin, were less active and less anxious than those fed with the milk collected during daytime, according to the study published in The Journal of Medicinal Food.

    Night milk quickened the start of sleep and caused the mice to sleep longer.

    While the effect of cow's milk harvested at different time has not been tested on humans up to now, taking melatonin drugs has been suggested to those who are struggling to fall asleep at night.

    Previous studies have also indicated that milk can be excellent for helping sleep because of the calcium content, which helps people to relax.

    Milk is also sugar-free and additive-free with nutritionists recommending skimmed milk as the best choice before bed as it is the least fattening. The more fat you take in before bedtime, the greater burden you will put on your body at night.

    What is life's greatest gift?{#blank#}1{#/blank#}Choice is the ability to select one course of action from a set of alternatives to achieve a goal. What is so great about choice? It transforms us from dumb animals into artists. Each of us becomes another Michelangelo. Choice becomes nothing other than the tool we use to sculpt (雕刻)our life. The tool doesn't come free, however, for the price of choice is responsibility.{#blank#}2{#/blank#}The reward is happiness.

    Life is not still. It is a flow.{#blank#}3{#/blank#}We constantly need to monitor where we are on our journey. We need to ask questions: Am I moving closer to my goals? If not, what corrective measures can I take? What action will I take now to readjust myself to my goals? Choice is power. Choice is at the heart of life. It is the creative power of life.

    {#blank#}4{#/blank#}And your life becomes more convenient or comfortable because of them. For example, you decide which stores to shop at and which gas station to go to. But the decisions that we make to sculpt our lives are far more important than deciding where to shop. The more we appreciate the difference between minor and major decisions, the greater the probability that we will experience happiness and fulfillment.

    Electric devices can seem like a “third party” in Some relationships because some partners spent more time on them than with each other.

    When Amanda Gao, a 26-year-old white collar worker in Beijing, went to a hotpot restaurant with her boyfriend on Friday night several weeks ago, she expected that they would have a good time together. To her disappointment, however, it did not turn out that later. As soon as they were led to their seats and she began to order dishes, he buried himself in his mobile phone.

    “It seemed that his phone was making its way between us. A date that should have belonged to us turned into one where my boyfriend dated a third party and I felt left out.” Gao said. Some people, like her, have found electronics have been sabotaging(破坏) their romantic relationships.

    A study, published in the journal Psych010kY of Popular Media Culture, in April, 2017, questioned nearly 200 college aged adults who were in committed(真诚的) relationships to report on their and their partner's smartphone dependency. The results showed people who were more dependent on their phones were less sure about their relationships, and people considered their partners excessively(过度地) dependent on their devices were less satisfied in their relationship.

    Lin Yuan, a relationship advisor in Beijing, noted that as more and more electronics come out and spice up people's lives, they are at the same time becoming a third party in relationships, especially for young people.

    Lin said she knew of some people who suggest that electronics should be kept out of bedrooms, which she considered challenging and hard to be put into practice for most couples. She recommended that if people are feeling neglected in their relationship, they need to respectfully let their partners know their feeling. “Communication is always the best and the most efficient way.” she said.

    Medicine is the most noble of all the arts, but owing to the ignorance of those who practice it, and those who inconsiderately form a judgment of them, it is now far behind all the other arts. Their mistake appears to me to arise principally from the fact that there is no punishment for the practice of medicine except disgrace, and that does not hurt those who are familiar with it. Such persons are like the figures introduced in tragedies, for as they have the shape, and dress, and appearance of an actor, but are not actors, so also physicians are many in title but very few in reality.

    Whoever is to acquire a competent knowledge of medicine ought to process the following advantages: a natural character; instruction; a favorable position for the study; early tuition; love for labor; leisure. First of all, a natural talent is required, for Nature leads the way to what is most excellent; then instruction in the art takes place, which the student must try to adopt by reflection, becoming an early pupil in a place well adapted for instruction. He must also bring to the task a love of labor and perseverance to ensure the instruction takes root.

    Instruction in medicine is like the culture of the productions of the earth. For our natural character, is, as it were, the soil; the principals of our teacher are, as it were, the seed. Instruction in youth is like the planting of the seed in the ground at the proper season. Diligent study is like the cultivation of the fields; and it is time which passes on strength to all things and brings them to maturity

    Having brought all these essentials to the study of medicine, and having acquired a true knowledge of it, we shall thus, in travelling around, be respected physicians not only in name but in reality. Inexperience is a bad trait, and does harm to those who possess it, nurturing either timidity or audacity(胆大安为). For timidity reveals a want of powers, and audacity a lack of skill. Physicians who are eager for power or those who are undertrained are not a blessing to a community.

    Those things which are sacred or noble, are to be delivered only to sacred persons; and it is wrong to import them to the profane until they have been initiated in the mysteries of the science.

    A good disguise keeps you hidden, right? Well, sometimes the best disguise is actually the most dazzling because research reveals that flashy metallic iridescence(金属彩虹色) can visually puzzle predators, which allows colorful prey to survive another day. Those surprising results appear in the journal Scientific Reports.

    Shining iridescent color, which changes depending on the angle from which it's viewed, is favored by everything from birds to beetles and blossoms to butterflies.

    "And in our research group we are of course interested in why this vivid metallic color is so widespread in nature." Karin Kjernsmo of the University of Bristol adds that in some cases the showy splashes of light are a sexual strategy. " Here I would like to point out that in some species, particularly those that display strong sexual dimorphism(雌雄两性), such as birds of paradise or some butterflies or fishes, the occurrence of iridescence is most likely driven by sexual selection. For example, in many of these cases it is the males that have these vivid iridescent colors and they use them in mate choice or they use them as a signal to attract mates."  But iridescence also shows up in situations where reproduction is not an issue. " So what we are studying now is whether natural selection imposed by predation(捕食行为) could explain the occurrence of iridescence in prey animals."

    The idea that eye­catching colors could be used as a cover­up isn't a new one." The father of camouflage theory, Abbott Thayer, really believed that iridescence should be categorized as a camouflage strategy. And he wrote in his famous lifework Concealing­Coloration in the Animal Kingdom, already in 1909, that 'brilliantly changeable or metallic colors are among the strongest factors in an animal's concealment'. And this sounds like a completely unreasonable thing to say, because how can colors that are both brilliant and changeable contribute to animal's concealment？"

    "In a similar way, we were asking whether iridescence, due to its changeability, could work as a form of camouflage by preventing shape recognition." Kjernsmo and her colleagues trained bumblebees to associate a particular shape—a circle or an oval—with a sugar reward. And they found that the bees, when given a choice, would preferentially visit the shape they knew to be sweet. But when the shapes were iridescent, the bees had trouble telling them apart. "It seemed that the strikingly iridescent surfaces on our targets visually broke up the otherwise recognizable shape of the targets, which made them hard to distinguish." As for making use of this method for hiding in plain sight, "Any practical applications is of course directly linked to any industry that has an interest in camouflage, that is how to conceal objects or make them more difficult to recognize." The researchers are currently conducting experiments with birds, which often prey on iridescent insects to see if it helps to have a bird's­eye view.
