What Will Be Done-With All This Denim?

    All the denim (牛仔布) will be donated to Cotton From Blue to Green, which recycles jeans into UltraTouch Natural Cotton Fiber Insulation (纤维隔热材料), which is used to help build houses in places that have been damaged by hurricanes and other natural disasters. Your jeans will help keep clothes out of landfills (垃圾场), and build houses for families to live in! UltraTouch is made of 85% recycled fibers and is an environmentally safe, natural cotton fiber insulation.

It's a Fact

    It takes about 500 pairs of jeans to recycle enough denim to insulate one average-size U.S house.

Here's How You Can Get Involved!

1). Get a parent's permission and select as many denim jeans as you like. (Any denim clothing is OK)

2). The denim must be used.

3). The denim can be any brand.

4). The denim can be any color or size but must have been worn by a human (no doll clothes!).

5). Jeans must be received by June 30, 2017.

    What are two things that make humans different from animals? One is language, and the other is music. It is true that some animals can sing (and many birds sing. better than a lot of people). However, the songs of animals, such as birds and whales, are very limited. It is also true that humans, not animals, have developed musical instruments.

    Music is strange stuff. It is clearly different from language. However, people can use music to communicate things—especially their emotions. When music is combined with speech in a song, it is a very powerful form of communication.

    If music is truly different from speech, then we should process music and language in different parts of the brain. The scientific evidence suggests that this is true. Sometimes people who suffer brain damage lose their ability to process language. However, they don't automatically lose their musical abilities. For example, Vissarion Shebalin, a Russian composer, had a stroke in 1953. It injured the left side of his brain. He could no longer speak or understand speech. He could, however, still compose music until his death ten years later. On the other hand, sometimes strokes cause people to lose their musical ability, but they can still speak and understand speech.

    Why does music have such a strong effect on us? That is a harder question to answer. Geoffrey Miller, a researcher at University College, London, thinks that music and love have a strong connection. Music requires special talent, practice, and physical ability. That's why it may be a way of showing your fitness to be someone's mate. For example, singing in tune or playing a musical instrument requires fine muscular control. You also need a good memory to remember the notes. And playing or singing those notes correctly suggests that your hearing is in excellent condition. Finally, when a man sings to the woman he loves, it may be a way of showing off.

    However, Miller's theory still doesn't explain why certain combinations of sounds influence our emotions so deeply. For scientists, this is clearly an area that needs further research of sounds influence our emotions so deeply. For scientists, this is clearly an area that needs further research.

    When Rebecca Saxon was diagnosed with cancer at the young age of 27, she thought her life was over. But in her darkest hour, inspiration struck and she found a way of turning her misfortune into advantage.

    Following her cancer treatment, Rebecca launched a successful business "Something Blue Bridal Shoes"—a unique range of wedding footwear, which came out of the fashion pictures she drew while recovering in her hospital bed.

    Rebecca, from London, says, "I started designing wedding shoes with blue soles (鞋底) when I was halfway through my cancer treatment. I had a hit when I was diagnosed with cancer but I decided that I was going to pick myself up and fight this cancer. The pictures were my release and the way I got through the many hours spent in a hospital room. I had no idea what was going to happen to me, but I knew I had to be positive if I was going to overcome this treatment. I told myself this was not going to be the end for me. I decided to fight with my negative feelings and start drawing."

    Rebecca had always loved fashion since she was younger. Several of her friends were getting married at the time when she was ill. "So at first, I would be drawing designs for wedding dresses and other clothes. But then I started drawing wedding footwear—designing shoes with blue soles which were very comfortable too. I thought it would be a lovely way of combining the 'something old, something new, something borrowed, something blue' tradition. Drawing really helped me deal with my treatment," said the brave girl.

    With the encouragement of her boyfriend, she turned her dreams into her reality and set up "Something Blue Bridal Shoes". Each beautiful shoe has a blue sole, combining the age-old tradition of what a bride should wear at her wedding for good luck.

    It was a comfortable sunny Sunday. I was going to meet an old university friend I hadn't seen for years, and was really excited.

    My train was running a little late, but that was no big problem - I could text him to say I would be delayed. He would understand. But… where was my mobile phone? I had that familiar sinking feeling. Yes, I'd left it at home.

    No mobile phone. I'm sure I'm not alone in feeling anxious, on edge and worried when I don't have my phone with me. In fact, I know I'm not alone: two-thirds of us experience 'nomophobia' (无手机恐惧症), the fear of being out of mobile phone contact.

    That's according to a study from 2012 which surveyed 1,000 people in the UK about their relationship with mobile phones.

    It says we check our mobile phones 34 times a day, and that 18-24 year-olds, especially girls, are the most likely to suffer fear of being without their mobiles: 77% of them say they are unable to be apart from their phones for more than a few minutes.

    Do you have nomophobia?

    • You never turn your phone off

    • You frequently(频繁地) check for texts, missed calls and emails

    • You always take your phone to the bathroom with you

    • You never let the battery run out

    It's funny to think that around 20 years ago the only people with mobile phones would be businessmen carrying their large, plastic 'bricks'. Of course, these days, mobile phones are everywhere. A UN study from this year said there would be more mobile phones than people across the world by the end of 2020.

    And when there are more phones than people in the world, maybe it's time to ask who really is in charge(主管)? Are you in control of your phone, or does your phone control you?

    So, what happened with my university friend? When I arrived a few minutes late he just laughed and said: "You haven't changed at all – still always late!" And we had a great afternoon catching up, full of jokes and stories, with no desire(欲望) to check my phone.

    Not having it with me felt strangely free. Maybe I'll leave it at home on purpose next time.

    City trees grow faster and die younger than trees in rural forestry, a new study finds. Over their lifetimes, then, urban trees will likely absorb less CO₂ from the air thah forest trees.

    As we all know, the earth would be freezing or burning hot without CO₂. However, CO₂ is a greenhouse gas, meaning it traps energy from the sun as/heat. That makes temperatures near the ground rise. Human activities, especially the widespread burning-of fossil(化石)fuels, have been sending extra greenhouse gases into the air. This has led to a rise in average temperatures across the globe.

    Studies had shown forests readily absorb CO₂, but there hadn't been much data on whether city trees grow, die and absorb CO₂ at the same rate as forest trees do. So some researchers decided to find out.

    To figure out how quickly trees were growing, researchers tracked their diameters (the width of their trunks) between 2005 and 2014. A tree's diameter increases as it grows, just as a person's waist size increases as they gain weight. About half the weight of a tree is carbon, research has shown. Most of the rest is water. Over the nine years' tracking, the researchers found city trees absorbed four times as much carbon from the air as forest trees. However, they were twice as likely to die. So over the lifetime of each type of tree, forest trees actually absorbed more CO₂.

    City trees grew faster because they had less competition for light from their neighbors. In a forest, trees tend to grow close together, shading their neighbors. Street trees also benefit from higher levels of nitrogen (氮)in rainwater. Nitrogen helps plants grow. Waste gases from gas-burning cars also contain nitrogen, thus enriching city air with nitrogen. Later, rainwater may wash much of it to the ground. Some street trees may also have better access to water than trees in the country because the underground water pipes can leak.

A new study examined scientists' peer reviews, or researchers' official statements on others' work, across multiple AI-related conferences. At one such conference, those peer reviews used the word "meticulous" — a buzzword often associated with generative A.I., like ChatGPT — almost 3,400 percent more than the previous year. Other major conferences showed similar patterns. In other words, many researchers were handing, at least, parts of their peer review over to A.I.

What's going on in science is a slice of a much bigger problem. Any viral post on social media now almost certainly includes A.I.-generated elements. There are synthetic videos for children on YouTube, like music videos about parrots where the birds have eyes within eyes, singing in an unnatural voice. The narratives make no sense, and characters appear and disappear randomly.

As a neuroscientist, this worries me. Isn't it possible that human culture contains within it cognitive micronutrients — things like reasonable sentences, narrations and character continuity — that developing brains need? Einstein supposedly said: "If you want your children to be intelligent, read them fairy tales. If you want them to be very intelligent, read them more fairy tales." But what happens when a child is consuming mostly A.I.-generated waste? We find ourselves in the middle of a vast developmental experiment.

A.I.'s cultural pollution is driven by a desire to fill the Internet's appetite for content as cheaply as possible, which in turn pollutes our culture. And despite public appeals to act against it, A.I. companies are dragging their feet because it goes against the industry's bottom line to have detectable products, which they fear might weaken the model's performance, although there is no current evidence.

To deal with this general refusal to act, we need a Clean Internet Act. Perhaps the simplest solution would be to force built-in watermarking to A.I. generated outputs, like patterns not easily removable. Just as the 20th century required action to protect the shared environment, the 21st century is going to require actions to protect a different but equally critical resource: our shared human culture.
