There are two factors (因素) which decide an individual's intelligence (智商). The first is the sort of brain he is born with. Human brains differ greatly, some being more capable (有能力) than others. But no matter how good a brain he has to begin with, an individual (个体) will have a low order of intelligence unless he has opportunities to learn. So the second factor is what happens to the individual—the sort of environment in which he is brought up. If an individual has less chances environmentally, it is likely that his brain will fail to develop and he will never arrive at the level of intelligence of which he is capable.

    The importance of environment in deciding an individual's intelligence can be shown by the case history of the twins. When they were three months old, their parents died, and they were placed in different homes. Peter was brought up by parents of low intelligence in a separate community with poor educational opportunities. Mark was brought up in the home of well-to-do opportunity to be encouraged intellectually.

    This environmental difference continued until the twins were in their late teens, when they were given tests to measure their intelligence. Mark's IQ was 125, twenty-five points higher than the average and fully forty points higher than his twin brother. Given equal opportunities, the twins, having similar brains, would have tested at roughly the same level.

    So many of us hold on to little resentments that may have stemmed from an argument, a misunderstanding, or some other painful event. Stubbornly, we wait for someone else to reach out to us―believing this is the only way we can forgive or rekindle(重新点燃) a friendship or family relationship.

    An acquaintance of mine whose health isn't very good, recently told me that she hasn't spoken to her son in almost three years. "Why not" I asked. She said that she and her son had had a disagreement about his wife and that she wouldn't speak to him again unless he called first. When I suggested that she be the one to reach out, she resisted initially and said, "I can't do that. He's the one who should apologize." She was literally(简直) willing to die before reaching out to her only son. After a little gentle encouragement, however, she did decide to be the first one to reach out. To her amazement, her son was grateful for her willingness to call and sincerely said sorry to her. As is usually the case when someone takes the chance and reaches out, everyone wins.

    Whenever we hold on to our anger we turn "small thing" into "big thing" in our minds. We start to believe that our positions are more important than our happiness. They are not. If you want to be a more peaceful person you must understand that being right is to let go, and reach out. Let other people be right. This doesn't mean that you're wrong. Everything will be fine. You'll experience the peace of letting go as well as the joy of letting others be right. You'll also notice that as you reach out and let others be "right" they will become less defensive and more loving toward you. They might even reach back. But if for some reason they don't that's okay too. You will have the inner satisfaction of knowing that you have done your part to create a more loving world and certainly you'll be more peaceful yourself.

    Have you ever run into a careless cell phone user on the street? Perhaps they were busy talking, texting or checking updates on We Chat without looking at what was going on around them. As the number of this new “species” of human has kept rising, they have been given a new name—phubbers (低头族).

    Recently, a cartoon created by students from China Central Academy of Fine Arts put this group of people under the spotlight. In the short film, phubbers with various social identities bury themselves in their phones, a doctor plays with his cell phone while letting his patient die, a pretty woman takes selfe in front of a car accident site, and a father loses his child without knowing about it while using his mobile phone, a chain of similar events eventually leads to a series of destruction.

    Although the ending sounds overstated, the damage phubbing can bring is real.

    Your health is the first to bear the consequence (后果) of it. “Constantly bending your head to check your cell phone could damage your neck,” Guangming Daily quoted doctors as saying. “The neck is like a rope that breaks after long-term stretching.” Also, staring at cell phones for long periods of time will damage your eyesight gradually, according to the report.

    But that's not all. Being a phubber could also damage your social skills and drive you away from your friends and family. At reunions with family or friends, many people tend to stick to their cell phones while others are chatting happily with each other and this creates a strange atmosphere, Qilu Evening News reported.

    It can also cost you your life. There have been lots of reports on phubbers who fell to their death, suffered accidents, and were robbed of their cell phones in broad daylight.

    Almost every second of every day an older adult falls in the United States. That's approximately 29 million falls per year and nearly 27, 000 deaths, according to the Centers for Disease Control and Prevention.

    Still in the stating stage, the Active Pelvis Orthosis (APO) system in Switzerland wants to make a lightweight, wearable exoskeleton (外骨骼) that could detect signs of balance loss and assist with balance recovery to keep the elderly wearer from falling, only when needed.

    Other exoskeletons, either in development or on the market today, assist with movement and make heavy objects feel lighter. Mobility-impaired people can walk again. But none of these devices predict what the wearer is going to do next and take measures to correct an unsteady move.

    The 3 kilogram (6.7 pound) exoskeleton was built entirely from scratch by the research team and is designed to be worn on the lower half of the body. A waistband connects to two movable carbon fiber braces (支架), each one positioned on the outer side of a leg. Tiny motors and so-called "adaptive oscillators" (适配振荡器) in the computer circuits use a special process to detect the, wearer's unique paces. That part takes just a few minutes.

    While wearing the exoskeleton, a person may feel the braces and the motors pushing slightly on their legs. If their paces go against normal, the motors create a force in the braces that cause them to stiffen up and push a little more strongly against the legs, which provides stability.

    In the next three years, the APO hopes to develop something that is commercially available.

    Did you know that if you attach a weighed stick to the back of a chicken, it walks like a dinosaur?

    No, you did not know(or care to know) such things, but now you do! Thanks to this year's winners of the 12 Noel Prize! Now in is 251h year, the lg Nobel is the goofy younger cousin of the honored Nobel Prize. It applauds achievements in the fields of medicine, biology, physics, economies.literature.etc. Every September at Harvard University, awards are presented in 10 categories that change year to year, depending on - according to the organization - what makes the judges "laugh, then think".

    The ceremony officially begins when audience members launch paper airplanes at an assigned human target on the stage, then speakers only have 60 seconds to present their research. In previous year, the one-minute rule was imposed by a young girl - nicknamed Miss Sweetie Poo -who would go up to the platform and repeat the words: "Please stop, I'm bored." in a sharp tone until the speaker left the stage.

    Fortunately for candidates though, the Ig Informal Lectures are held afterwards on Saturday to give presenters more time to explain the crazy things they're working on.

    The research can seem more like the brainchildren of teenage boys than of respectable adults. Justin Schmidt won the physiology Ig for creating the "Sting(蛰) Pain Index," which rates the pain people fell after getting stung by insects. Smith pressed bees against 25 different parts of his body until they stung him. Five stings a day for 38 days, Smith concluded that the most painful sting locations were the nose and the upper lip. Ouch.

    As silly as they sound, not all of the Ig awards lack scientific applicability, A group of scientists from 12 different counties won in the medicine category for accurately diagnosing patients with appendicitis (阑尾炎) based on an unusual measurement: speed bumps(减速带) . They found that patients are more likely to have appendicitis if they report pain during bumpy car rides.

    All these weird experiments have just one thing in common. They're improbable. It can be tempting to assume that "improbable" implies more than that--implies bad or good, worthless or valuable, trivial or important. Something improbable can be any of those, or none of them, or all of them, in different ways. And what you don't expect can be a powerful force for not only entertaining science, but also for the boundary-pushing science we call innovation.

    Spiders are master builders, expertly turning silk into complex 3D webs that serve as their home and hunting ground. To gain a deeper understanding of their world, scientists have translated the structure of a spider's web into music, which could have applications ranging from better 3D printers to cross-species communication. 

    "The spider lives in an environment of vibrating strings, "says Markus Buehler, the project's principal investigator. "They don't see very well, so they perceive their surroundings by detecting vibrations, which have different frequencies." Such vibrations occur, for example, when the spider stretches a strand of silk during construction or when the wind or a trapped fly moves the web. 

    The researchers scanned a natural spider web to capture 2D cross-sections and reconstructed its 3Dnetwork using a mathematical model. They assigned different frequencies of sound to strands of the web, creating musical "notes" that they combined in patterns based on the web's 3D structure to generate music. Then they made a harp-like (像竖琴的) virtual instrument and played the spider web music in several live performances around the world, creating an inspiring harmony of art and science. 

    To gain insights into how spiders build webs, the researchers also scanned a web during construction. transforming each stage into music with different sounds. "The spider's way of ‘printing' the web is remarkable because no support material is used, as is often needed in current 3D printing methods," Buebler says. This knowledge could help develop new 3D printers that work like spiders, enabling them to construct complex structures without using additional materials for support. 

    The team is also interested in learning how to communicate with spiders in their own language. They recorded web vibrations produced when spiders performed different activities. such as building a web. communicating with other spiders or sending signals to admirers. "Now we're trying to generate signals to basically speak the language of the spider, "Buehler says. "If we expose them to certain patterns of vibrations, can we affect what they do or can we begin to communicate with them? Those are really thrilling ideas, and I believe they could be achieved in the near future."
