Loneliness is like a disease, and what's worse, it's contagious. It can spread from one person to another, according to the recent research that stresses the power of one person's emotions to affect even people he doesn't know.

    The new analysis, involving 4,793 people who were interviewed every two years between 2005 and 2015, showed that a friend of a lonely person was 52％ more likely to develop feelings of loneliness by the time of the next interview. A friend of that person was 25％ more likely, and a friend of a friend of a friend was 15％ more likely.

“Loneliness is not just the property of an individual. It can be transmitted across people—even people you don't have direct contact with,” said John T. Cacioppo, a psychologist of the University of Chicago who led the study published in the December issue of the Journal of Personality and Social Psychology.

    Loneliness has been linked to medical problems, including depression, sleep problems and generally poorer physical health. Identifying some of the causes could help reduce the emotion and improve health, experts said.

Although the study did not examine how loneliness spreads, Cacioppo said another research has provided clues. “Let's say for whatever reason you get lonely. You then interact with other people in a more negative fashion. That puts them in a negative mood and makes them more likely to interact with other people in a negative fashion and they minimize their social ties and become lonely,” Cacioppo said.

According to Cacioppo, loneliness spread more easily among women than men, perhaps because women were more likely to express emotions.

Lonely people become less and less trusting others. This makes it more and more difficult for them to make friends－and more likely that society will reject them. Therefore, it is important to recognize and deal with loneliness．Cacioppo emphasizes people who have been pushed to the edges of society should receive help to repair their social networks.

     An Iowa elementary school principal was taped onto a gym wall by his students on Friday，November 5th，2014.Principal Ryan Castle of Colorado Elementary School in Iowa，America let 27 students in his school tape him to a gym wall.He stayed up there，with his both feet suspended(悬浮) above the floor，from the morning until lunch time.

     Ryan Castle earlier promised to the students that if they sold 10，000 fall festival tickets，he agreed to be taped onto a gym wall at his school.Unexpectedly，the students had sold 11，000 fall festival tickets by October the 31st.He kept his promise and he let the students tape him onto a gym wall.

     Twenty－seven top－selling students were allowed to tape Ryan Castle up.Ryan Castle was photographed wearing a fake mustache because it was Mustache Day for the school.It was not the first time that principals were taped onto a wall in America.Ryan Castle's case comes after at least three other recent cases of school principals being taped up on the wall for a good cause.

     On last Wednesday，Jay Woller of La Crescent Elementary School in Minnesota America was taped onto a wall after $21，000 was collected by his students through fundraising.And last month，Randy Ten Pas of Hull Christian School in Iowa America was taped onto a wall with duct tape.He was taped on a 300－feet－tall building wall in his school—as a symbolic reward for students' fundraising efforts coming to $3，300.Randy Ten Pas was photographed wearing a green cap and with a drawing of the Denver Broncos logo(商标) next to him.At St.Mary Catholic School in Orange，Texas，principal Donna Darby offered a similar ticket－selling challenge to students in September.He was also taped onto the wall in the end.They kept their word and set good examples to their students.

    Regarded as one of the English language's most gifted poets, John Keats wrote poetry that concentrated on imagery, human nature, and philosophy. Although Keats didn't receive much formal literary education, his own studies and passion brought him much success. Additionally, his own life situation influenced his poetry greatly.

    Growing up as a young boy in London in a lower middle-class family, the young John didn't attend a private school, but went to a public one. His teachers and his family's friends regarded him as an optimistic boy who favored playing and fighting much more than minding his studies. After his father's death in the early 1800s, followed by his mother's passing due to tuberculosis (肺结核), he began viewing life differently. He wanted to escape the world and did so by reading anything he could get his hands on.

    At around the age of 16, the teenage John Keats began studying under a surgeon so that he too might become a doctor. However, his literary appetite had taken too much of his fancy, especially with his addiction to the poetry of Ehmund Spenser. He was able to have his first full poem published in the Examiner in 1816, entitledO Solitude!If I Must With Thee Dwell. Within two months in 1817, Keats had written an entire volume of poetry, but was sharply criticized by a magazine. However, the negative response didn't stop his pursuit of rhythm.

    John Keats' next work was Endymion, which was published in May 1818. The story involves a shepherd who falls in love with the moon goddess and leads him on an adventure of one boy's hope to overcome the limitations of being human. Following Engymion, however, he tried something more narrative-based and wrote Isabella. During this time, John Keats began seeing his limitations in poetry due to his own limit in life experiences. He would have to have the “knowledge” associated with his poems. His next work wasHyperionthat would attempt to combine all that he learned. However, a bout (发作) with tuberculosis while visiting Italy would keep him from his work and eventually take his life in 1821.

Cattle manure(粪肥) has become one of the world's greatest environmental killers, but one Dutch artist is using chemistry to turn it into something that is both eco-friendly and valuable.

In recent years, scientists around the world have made great progress in their attempts to recycle cattle manure, including turning it into natural fertilizer, but Eindhoven designer Jalila Essaidi didn't think they were efficient enough to solve the global manure problem. So she started on her very own solution, one that approached animal waste as a valuable material that could be processed into useful products.

She started by separating the waste, with the dry manure used to get pure cellulose(纤维素) from the grass that cows eat. From the wet manure, she got acids used to create a natural liquid plastic which was used to make fiber that are later turned into fabric(material used for making clothes).

This new material was named Mestic, from mest, the Dutch word for manure. Essaidi claim that it has the same function as plastic from fossil fuels, but is bio-degradable(可生物降解的). Better yet, the degradability can be dealt with in the lab, making it possible to create materials that last for different periods of time depending on their purpose. "This is not the first time that scientists have been looking for ways to solve the manure problem, but it is the first time that manure is being considered as a valuable resource." the Dutch designer said.

Last year, Jalila Essaldi partnered with the city of Eindhoven to produce a fashion show using Mestic-based fabrics. Her Mestic collection was so impressive that clothing giant H&M awarded her the Global Change Award and a $1million prize. And cow manure is just the beginning of Jalila Essaldi's experiments with animal waste. "After cows, we'll deal with pigs and other animals," she said.

Recycled, reused and renewable textiles（纺织品）only go so far in solving the fast-fashion crisis, writes Alexandra Carlton. The answer may lie in consumption.

Australia is the world's second-largest consumer of clothing, generating 800,000 tonnes of textile waste yearly. Individuals consume about 27 kilograms of new clothes annually and cast 23 kilograms of waste. Globally, the situation is even more severe, with an estimated 92million tonnes of clothing waste produced each year. This equates to a truckload of clothes entering landfills every second.

If you want to stop our unwanted clothes from jamming the planet, you'd assume that reusing and recycling would lead the discussion. However, full clothes recycling—breaking clothes down to their base fibres to create new ones—is no simple task. Clothes consist of various fibres, fasteners, and decorations that traditionally require painstaking manual（手工的）separation. Yet, innovation is underway, such as the Swedish large-scale sorting facility Siptex, where textiles can be sorted by color and material using infrared（红外线）technology.

Brands like Adelaide's Autark focus on minimizing output. "I keep my collections tightly designed and production numbers slim," says designer Sophia McMahon. Sometimes this means she doesn't have the exact clothes someone wants in store, but customers are patient while she makes items to order because they understand her brand's essence.

Startups like AirRobe are giving clothes a second life and could be part of the solution. The clothing resale market is currently worth 49 billion and is expected to reach 103 billion by 2025. AirRobe lets customers add new purchases to their digital wardrobe so they can be resold later without uploading photos or descriptions. "The ‘re-economy'—the reuse and recycle market sector—will be a real opportunity for us," says Erica Berchtold, CEO of The Iconic.

Researchers Samantha Sharpe and Taylor Brydges from the University of Technology Sydney advocate a widespread shift among consumers towards buying fewer, higher-quality clothes besides these innovations.
