“We haven't found anything that we can't recycle!”

    Cigarette ends are everywhere—littering our streets and beaches—and for decades they've been thought of as“unrecyclable”. But a New Jerseybased company, called TerraCycle, has taken on the challenge, and has come up with a way to recycle millions of cigarette ends and turn them into industrial plastic products. Its aim is to recycle things that people normally consider impossible to reuse.

    Obviously it would be even better for the environment if everyone just stopped smoking, but the statistics show that although there has been an increase in anti-smoking ads and messaging, between 2000 and 2014, global sales of cigarettes increased by 8 percent, and a whole lot of those cigarette ends are ending up as trash. Since most of our litter eventually ends up in waterways, cigarette ends can surely pollute the surrounding environment. “It only takes a single cigarette end to pollute a liter of water, ” TerraCycle founder, Tom Szaky, said. “Animals can also mistake littered cigarette ends for food.”

    So how do you go about turning all those poisonous ends into something useful? TerraCycle does this by first breaking them down into separate parts. They mix the remaining materials, such as the tobacco and the paper, with other kinds of rubbish; and use it on non-agricultural land, such as golf courses. The filters (过滤嘴) are a little harder. To recycle these, TerraCycle first makes them clean and cuts them into small pieces, and then combines them with other recycled materials, making them into liquid for industrial plastic products.

    They're now also expanding their recycling offerings to the rest of the 80 percent of household waste that currently can't be recycled, such as chocolate packaging, pens, and mobile phones. The goal is to use the latest research to find a way to stop so much waste ending up in landfill (垃圾填埋), and then get companies to provide money for the process. And so far, it's working.

    “We haven't found anything that we can't recycle,”communications director of Terra Cycle, Albe Zakes, said. “But with the amount and variety of packaging and litter in the world, we are always looking for new waste streams to address.”

    Some people shy away from traveling alone while a few welcome it. So, what is it that makes traveling alone an attractive choice?

    First of all, the travel plan and all the decisions you make are yours alone. You don't need to worry about any other person or group. In other words, there are no arguments. Actually, you can be completely selfish.

    Traveling alone is also a great confidence builder. Yes, at times it can feel a bit lonely, but that is just one of many problems you will have to solve yourself, along with making your own preparations and setting your own goals.

    Besides, have you noticed that when you're on your own, people are more willing to start a conversation with you? Interestingly, people tend to keep a distance from couples and groups. However, the lone (独自的) traveler looks ready to connect with their fellow human beings and more likely to get into pleasant conversation about their trips.

    Here are two more exciting reasons why you should consider traveling alone. You will find you learn the language faster when you don't have someone else talking to you in your own language all the time. You are forced to communicate in the foreign language when you travel alone in a country that doesn't speak your native language. In addition, when you're on your own, you're free to meet someone who might turn out to be very important in your life.

    Of course, there may be things stopping you: You fear the unknown, or you have friends who may be upset by your decision to take off by yourself. You will have to make them believe the value of traveling done and allay any fears they might have, but with the technology at our fingertips, you can include them in the adventure.

    Do you find it difficult to put down your mobile phone?

    If yes, you're not alone. These days, many people suffer from the stress of FOMO (fear of missing out). They reach of their mobile phones when they wake up in the morning, and for the rest of the day, they constantly check their social media apps for the latest updates.

    Despite the convenience smart phones bring, many people struggle with their digital habits. This is why Google introduced an app called Dashboard for Android operating system. This new app includes well-being functions that aim to help users manage the time they spend on their digital devices.

    It all starts with a bird's-eye view. Dashboard allows users to look at all the details of their phone habits. For example, a user can see how many times they're unlocked their phone and how many times they're checked their social media apps, as well as how much time they spend on each app every day.

    Once the users see this information, they'll be able to make some changes. With the App Timer function, users can set a time limit for how long they can use each app for every day.

    But even if users become more mindful of their usage, they're still likely to be drawn in by notification（通知）. Such feature automatically（自动地）silences incoming calls and notifications when a user puts their phone face down.

    If people truly want to make full use of their free time instead of losing hours using their smart phones, these new functions are just one way of doing that.

    The easiest answer would be just to use your willpower.

    Today, we are constantly bombarded with media reports about research on the right diet to follow to help us maintain a healthy lifestyle or lose weight—but it's hard to know which one to pick and, once chosen, it's harder still to stick to it. And now there's another choice to get our teeth into.

    A flexitarian(弹性素食者)diet involves eating plant—based foods and only occasionally eating meat and fish. This eating style allows you to supplement some ingredients that you wouldn't get in a stricter vegan(素食主义者)diet—another trend growing in popularity. And like veganism, flexitarianism isn't about eating carefully to help you lose a few pounds—it's something people choose for ethical reasons, to help the planet. And a study into the global food system and how it affects the climate, has found that eating mainly plant-based foods is one of three key steps towards a sustainable future for all by 2050.

    This research found that food waste will need to be halved and farming practices will also have to improve to achieve this. But without a single solution, a combined approach is needed. Dr Marco Springmann from the University of Oxford was one of the lead authors of the report. He told the BBC “We really found that a combination of measures would be needed to stay within environmental limits and those include changes towards healthier more plant—based diets.”

    But whereas vegans think it's wrong for animals to be killed for food, flexitarians believe eating meat once in a while is acceptable. And Dr Springmann agrees—as long as we “treat it as a luxury, it's probably OK but you shouldn't have more than one serving of red meat, which includes beef and pork, per week.” And here's another fact to digest: If we moved to this type of diet, the study found that greenhouse gas emissions from agriculture would be cut by more than half.

Three Feet From Gold

    Darby's uncle was caught by the "gold fever" in the gold—rush days, and went west to dig and grow rich. After months of labor, he was rewarded by the discovery of the shining ore (矿石). He needed machinery to bring the ore to the surface. So, with the "strike", he returned home. And with the help of Darby, he borrowed a lot of money. After buying the machinery and having it shipped, Uncle and Darby went back to work the mine.

    The first car of ore was mined. And the returns proved they had one of the richest mines in Colorado! Down went the drills! Up went the hopes of Uncle and Darby!

    Then something happened! The vein (矿脉) of gold ore disappeared! They drilled on, but all in vain. Finally, they decided to quit and sold the machinery to a junk man for a few hundred dollars. The junk man called in a mining engineer to look at the mine and do a little calculating. The engineer's calculations showed that the vein would be found just three feet from where the Darbys had stopped drilling! The junk man took millions of dollars in the vein, because he knew enough to seek experts' advice before giving up.

    Most of the money which went into the machinery was borrowed through the efforts of Darby, who was then a very young man. The money came from his relatives because of their faith in him. He paid back every dollar of it, although he was years in doing so.

    Long afterwards, Mr. Darby made another discovery that desire can be changed into gold. This discovery came after he went into the business of selling life insurance. Remembering that he lost a huge fortune, for he stopped three feet from gold, Darby profited by the experience in his chosen work, saying to himself, "I stopped three feet from gold, but I never stop because men say 'no' when I ask them to buy insurance."

    Darby sold more than million dollars in life insurance annually. He owes his "stick-ability" to the lesson he learned from his "quit-ability" in the gold mining business.

    Facebook says it is working on technology to allow us to control computers directly with our brains. It is developing "silent speech "software to allow people to type at a rate of 100 words per minute, it says. The project, in its early stages, will require new technology to detect brainwaves without needing invasive operation. "We are not talking about monitoring your random thoughts," assured Facebook's Regina Dugan. "You have many thoughts, and you choose to share some of them. We're talking about monitoring those words. A silent speech interface（界面）-one with all the speed and flexibility（灵活）of voice. "

    Ms Dugan is the company's head of Building 8, the firm's hardware research lab. The company said it intends to build both the hardware and software to achieve its goal, and has employed a team of more than 60 scientists and academics to work on the project.

    On his Facebook page, Mark Zuckerberg added, "Our brains produce enough data to stream four HD（高清）movies every second. The problem is that the best way we have to get information out into the world-speech-can only send about the same amount of data as a 1980s modem. We're working on a system that will let you type straight from your brain about five times faster than you can type on your phone today. Finally, we want to turn it into a wearable technology that can be produced in quantity. "

    Technology is going to have to get a lot more advanced before we can share a pure thought or feeling. but this is a first step. Other ideas detailed at the company's developers conference in San Jose included work to allow people to "hear" through skin. The system, comparable to Braille, uses pressure points on the skin to pass information. "One day, not so far away, it may be possible for me to think in Chinese, and you to feel it instantly in Spanish,"Ms Dugan said.
