2 . Some songs might speak to your soul even if you don't know the words. The almost magical way that music reflects and influences our emotions led American poet Henry Wadsworth Longfellow to declare it the “universal language of mankind”. But how universal is it really?
A team of more than a dozen researchers and countless undergraduates set out to collect and interpret descriptions and recordings of musical performances around the world. Their first finding: Music is indeed universal. Or at least statistical modeling strongly suggests that more than 99% of societies have music. Then, they analyzed the song descriptions for sixty very different societies and looked at different qualities related to song performance.
As they classified the songs, they found that three dimensions (方面) accounted for more than a quarter of the variability between songs. The first was how formal or informal a song was. Songs high in formality had large audiences and lots of instruments, often involved ceremonial events, and frequently had adult-only audiences. Informal events had smaller audiences, including children, or no audience at all. The second was how arousing a song was to its listeners. Lively events involving lots of dancing were high on this dimension, while a low value reflected a calmer event, like someone singing to themselves or a baby. The last was how religious song was. Songs used in ceremonies were high in religiosity, while those without a spiritual context scored low.
The researchers applied their findings to four widespread categories of music: lullabies (摇篮), dance songs, love songs and healing songs, and found clear trend. Most dance was highly arousing and formal, but low in religiosity. Lullabies were mostly low in formality and low in arousal. And healing songs scored high in all dimensions while love songs were low in all dimensions. Even more interesting, the distribution of these behaviors was similar in all societies studied.
Scholars say that their database could fuel future research into even more inspiring questions about music universals. And their method might be used to pick out patterns in other hard-to-analyze fields, like storytelling or visual art.

3 . In an attempt to explore unknown environments, a Chinese team created an octopus (章鱼) — inspired flexible robotic arm capable of sensing and controlling objects in limited spaces and underwater.
According to the study published in the latest edition of Science Robotics, the robot allowed blindfolded human operators to guide its arm, using suckers (吸盘) to pick up various objects, including a toy shark and a smooth metal ball, via a single-finger glove.
This new invention created by a team of researchers, led by Wen Li from Beihang University was inspired by the octopus, which moves its soft arms to catch its games with sensitive suckers.
A simple strategy like this can be used as a model for robotic grasping, controllable with a few inputs, as well as a highly deformable arm with sensing capabilities.
Wen’s team fixed electronics and circuits into the robots while maintaining their deformability. The researchers presented a stretchable electronics-integrated soft octopus arm with 16 air-driven devices and multiple degrees of freedom.
The robot's stretchable, liquid-metal-based electronic circuit can stand super stretching force to perform tasks autonomously in a limited environment, findings from the study showed.
The soft arm with two rows of sensory sucking cups that connect with the wearer's finger can perform a reaching-grasping-returning motion across a range of up to 1.5 times its original arm length, similar to the biological counterpart (对应方), the study revealed.
“This robotic model provides new prospects and development ideas for the future interactive applications of flexible robots, including medical robots, seabed exploration robots, and so on” said the expert.

4 . Amy was a dear little girl, but she often tended to waste time in getting ready to do her tasks, instead of doing them at once as she ought to.
In the village in which she lived, Mr. Thornton kept a store where he sold fruit of all kinds, including berries in their season. One day he said to Amy, whose parents were quite poor, “Would you like to earn some money? ”
“Oh, yes,” replied she, “for I want some new shoes, and papa has no money to buy them with. ”
“Well, Amy,” said Mr. Thornton, “I noticed some fine, ripe blackberries in Mr. Green’s field today, and he said that anybody was welcome to them. I will pay you thirteen cents a quart (度量单位) for all you will pick for me”
Amy was delighted at the thought of earning some money; so she ran home to get a basket, intending to go immediately to pick the berries.
Then she thought she would like to know how much money she would get if she picked five quarts. With the help of her slate (书写板) and pencil, she found out that she would get sixty-five cents.
“But supposing I should pick a dozen quarts,” thought she, “how much should I earn then?” “Dear me!” she said, after figuring a while, “I should earn a dollar and fifty-six cents.”
Amy then found out what Mr. Thornton would pay her for fifty, a hundred, and two hundred quarts. It took her some time to do this, and then it was so near dinner time that she had to stay at home until afternoon.
As soon as dinner was over, she took her basket and hurried to the field. Some boys had been there before dinner, and all the ripe berries were picked. She could not find enough to fill a quart measure.

7 . For many students, math class is the subject of nightmares. Many who enthusiastically show off their counting skills in pre-school years later consider math class the most hated hour of the school day. The problem, according to a Stanford education professor, is a matter of mindset.
Jo Boaler, professor of mathematics education at Stanford, has studied how students learn math, to identify why so many students end up hating or fearing math, and, too often, underachieve. In her new book, Mathematical Mindsets, Boaler describes how society has traditionally valued one type of math learner — one who can memorize well and calculate fast — as opposed to others who have the same potential but may be deeper, slower.
The “testing culture” in American schools is a major problem for math learners, Boaler said, noting that exams and tests are far more pervasive (普遍) in math than other subjects. The combination of frequent testing, procedural teaching and uninteresting questions disconnected from students’ lives causes many students to regard math as a “cold, lifeless subject” without a human connection.
The good news is that any student’s negative perception of math can dramatically change, Boaler said. She works with Stanford psychology Professor Carol Dweck to deliver growth mindset interventions to teachers and students. A “growth mindset” is built around the idea that most basic abilities can be developed and expanded upon through dedication and hard work. By contrast, with a “fixed mindset,” people believe their basic qualities, like their intelligence or talent, are simply fixed traits (特征).
“When we open up mathematics and teach broad, visual, creative math, then we teach math as a learning subject instead of as a performance subject,” Boaler said, “The outcome is that the subject becomes deeper and filled with more connections, so students enjoy it more and achieve at higher levels.”
Critics such as Marina Ratner, professor of mathematics at the University of California, express skepticism towards moving away from traditional methods. Math is math; there is no shortcut. They argue that without solid basic skills, students might struggle with subjects like algebra (代数), let alone tackling any other higher-level STEM courses.
