1 . Hardware in general, and smartphones in particular, have become a huge environmental and health problem in the Global South’s landfill sites(垃圾填埋场).
Electronic waste (e-waste) currently takes up 5 percent of all global waste, and it is set to increase rapidly as more of us own more than one smartphone, laptop and power bank. They end up in places like Agbogbloshie on the outskirts of Ghana’s capital, Accra. It is the biggest e-waste dump in the world, where 10,000 informal workers walk through tons of abandoned goods as part of an informal recycling process. They risk their health searching for the precious metals that are found in abandoned smartphones.
But Agbogbloshie legally should not exist. The Basel Convention, a 1989 treaty, aims to prevent developed nations from unauthorized dumping of e-waste in less developed countries. The e-waste industry, however, circumvents regulation by exporting e-waste labelled as “secondhand goods” to poor countries like Ghana, knowing full well that it is heading for a landfill site.
A recent report found Agbogbloshie contained some of the most dangerous chemicals. This is not surprising: smart phones contain chemicals like mercury(水银), lead and even arsenic(砷). Reportedly, one egg from a free-range chicken in Agbogbloshie contained a certain chemical which can cause cancer and damage the immune system at a level that’s about 220 times greater than a limit set by the European Food Safety Authority (EFSA). Most worryingly, these poisonous chemicals are free to pollute the broader soil and water system. This should concern us all, since some of Ghana’s top exports are cocoa and nuts.
Some governments have started to take responsibility for their consumers’ waste. For example, Germany has started a project that includes a sustainable recycling system at Agbogbloshie, along with a health clinic for workers. However, governments cannot solve the problem alone, as there is an almost limitless consumer demand for hardware, especially when governments’ green policies are focused on issues like climate change.
Only the manufacturers can fix this. A more economically sustainable and politically possible solution is through encouraging hardware manufacturers to make the repair, reuse and recycling of hardware profitable, or at least cost-neutral.

2 . Exams never made me break out in a nervous sweat with tears threatening to ruin my already-trembling façade — but this one did. Even booking my piano exam reduced me to a blubbering mess of anxiety.
I feel permanently scarred inside churches — no longer admiring their beauty because, over the years, I have received such terrible marks from examiners hiding behind the stained-glass partitions. Despite being 15 — too old, too cool to be frightened — I remember trembling inside the bathroom stalls before my tests. I wished I never had to play in front of others.
But this time, after booking my Level 8 Royal Conservatory of Music piano exam, I went back to my normal routine. A little practice here, a little practice there. And then it happened.
My trusty, 10-year-old electric piano gave out. Middle C started to sound like an F-sharp and all other keys sounded like they were a fourth above their natural tone. Thankfully, my precious, boredom-saving buttons still worked. I could still change my piano’s settings from “piano” to “harpsichord .” I admit, it was a lot of fun banging on my wacky keys. Each note bonged like the sound on children’s TV shows when a character repeatedly runs into a wall.
Goofiness aside, I had to get my act together. I hated practicing but I really wanted a good mark. When I told my father what had happened to my piano, he only glared at me with disappointment, “When I was your age, I learned to be resourceful.”
Hmm. I had a broken piano, an exam coming up in a few months and a father who refused to buy me a new piano because he wanted to teach me a “life lesson”. I finally came upon a decision: I’d practice at school.
Going to a private school had to have its benefits, so I looked for a place to play. The school had many pianos but only a few in tune. Within a few days of searching, my piano books, my artistic best friend and I headed off to a music room at every available opportunity.
I loved finding new pianos in hidden corners of the school and I laughed at the dusty old historic pianos. They really had character. I spent hours in those music rooms while my friend honed her art skills in sketching and drawing. She suffered through my annoying, repetitive scales while I looked over my shoulder once in a while and admired her work. Not only did I become a better musician, but I also managed to gain a few subpar skills as an art critic.
As my exam drew close, all the music teachers knew to look for me in the piano rooms during recess, after school and late on Fridays. In anticipation of my assessment, one of my music teachers let me perform for her as a mini practice exam. To my surprise, she was greatly impressed.
Within a few months I went from not caring about my playing to feeling actually, maybe, kind of proud of my work. And over countless hours spent in my favorite, soundproof music room, I discovered that behind the piano, I could become anyone. Talking to other people never came easy to me, but I was able to express myself through music. I became overjoyed. It was like I had developed a sixth sense, one that only musicians could understand.
When I played, my worries about what others thought of me and how I viewed myself merged to reveal who I really am. All my adolescent musings made me feel like I was in a cage, but music gave me the key. Sitting behind a piano and creating music combined the movement of my body and the inner workings of my heart.
Music had never been the love of my life but that was changing. I loved the idea of being on a stage and creating something for others to enjoy and remember. Actually, it wasn’t a something, but rather a feeling that the audience would carry outside into a world where music wasn’t the only thing that people cared for.
When the time came to play in front of an examiner, instead of fearing my judge, I feared nothing but being unable to represent all my hard work. All the anxiety I had about going up on stage dimmed, and when the lights went on, all I could think about was the marvellous journey I’d had to get here. Trilling the keys reminded me of when I’d spent nearly two hours alone in a music room, more content than I had been anywhere else. Playing the melody reminded me of the bittersweet music experiences of past years.
Many days later, I received my mark. Not only did I earn a rarely mentioned “well done” and an 82 per cent, I had rewritten what music meant to me.
Now whenever I get caught up in the daily struggle, I remember the hard work that it took to reach my goal. Whenever I feel discouraged, I never forget to look at the gleaming keys of my new upright piano. As my father always says, some lessons are just learned the hard way.

3 . If your in-box is currently reporting unread messages in the hundreds or thousands, you might have a hard time believing the news: e-mail is on the decline.
At first thought, that might seem to be the case. The incoming generation, after all, doesn’t do e-mail. Oh, they might have an account. They use it only as we would use a fax machine: as a means to communicate with old-school folks like their parents or to fulfill the sign-up requirements of Web sites. They rarely check it, though.
Today’s instant electronic memos — such as texting and Facebook and Twitter messages — are more direct, more concentrated, more efficient. They go without the salutation (称呼语) and the signoff (签收); we already know the “to” and “from.” Many corporations are moving to messaging networks for exactly that reason: more signal, less noise and less time. This trend is further evidence that store-and-forward systems such as e-mail and voicemail are outdated. Instead of my leaving you a lengthy message that you pick up later, I can now send you an easily-read message that you can read — and respond to — on the go.
The coming of the mobile era is responsible for the decline of e-mail. Instant written messages bring great convince to people. They can deal with them at about any time: before a movie, in a taxi, waiting for lunch. And because these messages are very brief, they’re suitable for smart phone typing.
Does this mean e-mail is on its way to the dustbin of digital history? Not necessarily. E-mail still has certain advantages. On the other hand, tweets and texts feel ephemeral — you read them, then they’re gone, into an endless string, e-mail still feels like something you have and that you can file, search and return to later. It’s easy to imagine that it will continue to feel more appropriate for formal communications: agreements, important news, longer explanations.
So, e-mail won’t go away completely. Remember, we’ve been through a transition (过度) like this not so long ago: when e-mail was on the rise, people said that postal mail was dead. That’s not how it works. Postal mail found its smaller market, and so will e-mail. New technology rarely replaces old one completely; it just adds new alternatives.

4 . A strong coffee after a poor night's sleep is the kick-start many people need in the morning but new research suggests that it might be best to have a bite to eat first.
A study has found that drinking coffee first can have a negative effect on blood sugar control - a risk factor for diabetes （糖尿病）and heart disease.
“We know that nearly half of us will wake in the morning and, before doing anything else, drink coffee --- subjectively the more tired we feel, the stronger the coffee,“ said Professor James Betts, at the University of Bath in the UK.
For their study, researchers at the University of Bath got 29 healthy men and women to take part in three different overnight experiments, with at least a week between them.
In one, the participants had a normal night's sleep, roughly from 11 p.m. to 7 a.m., and were asked to consume a sugary drink on waking in the morning. They then experienced an interrupted night's sleep, where the researchers woke them every hour for five minutes by sending them text messages to which they had to respond — and upon waking were given the same sugary drink.
On another night, participants experienced the same sleep interruption, but this time were first given a strong black coffee 30 minutes before consuming the sugary drink.
They found that one night of interrupted sleep did not worsen the participants' blood sugar and insulin （胰 岛素）responses when compared to the normal night's sleep-- although previous research suggested that losing many hours of sleep or many nights of poor sleep could have a negative effect. However, strong black coffee consumed before breakfast actually increased the blood sugar response by around 50% — suggesting that relying on coffee after a bad night to stop feeling sleepy could limit your body's ability to tolerate the sugar in your breakfast.

5 . Do you remember the last time you received a postcard? The UK’s family-owned oldest postcard firm, which has been publishing postcards and calendars since 1880, will close this December. The reason? It says instead of penning a card, people are putting photos up on Facebook or Instagram or using WhatsApp to show friends and family at home just how much fun they’re having.
If you get a postcard from someone who’s away somewhere, it’s as much the thought that they’ve gone through the hassle (麻烦) of choosing a postcard, working out where to get a stamp from, finding a postbox and then the postcard making that journey through to you. That’s the value of the postcard. But that time has gone.
Brothers Charles and Harry Salmon, the fifth generation of the family to run the firm, said the popularity of social media had had a huge impact on the business. People are also tending to take shorter holidays, meaning they are likely to have arrived home long before their postcards. As a result the business was no longer viable.
“Increasingly challenging trading conditions and changes to the nature and size of the market for its publications have resulted in uncertainty over the future of its trade,’’ the brothers wrote in a letter to suppliers and newsagents.
As a result they were announcing a proposal to withdraw from publishing. The number of postcards sold each year is reported to have seen a sharp decline to about five million from 20 million just 25 years ago. But the firm said that as well as the drop in the number of postcards sent, “we have also had to consider that there are no more members of the family who wish to join the business.”

6 . Imagine a world where you move around in front of a personal computer in your own sound space. You listen to your favorite songs, play loud computer games or watch a movie — all without other people hearing the sound and without headphones.
That is the possibility presented by “sound beaming”, a new technology from Noveto Systems, an Israeli company. On Friday, the company introduced a desktop device that sends sound directly to a listener without the need for headphones or a special receiver.
Noveto Systems gave The Associated Press (AP) a chance to test its SoundBeamer 1.0 before its introduction. The AP’s Louise Dixon writes that listening to the device is like something from a science fiction movie.The sound seems so close that it feels like it is inside your ears while also in front, above and behind them.
Noveto expects the device will have many uses. Office workers could listen to music or conference calls without others hearing. People could play a game, a movie or music without waking up others in the same room. Because the device does not use headphones, it is possible to hear other sounds in the room clearly.
The device uses a 3-D sensing module that finds and follows the ear position of the listener. It sends ultrasonic waves (超声波) to create sound pockets by the user’s ears. The 3-D method creates sound on all sides of the listener, therefore the listeners feel completely transported into the scene.
By changing a setting, the sound can follow a listener around when he moves his head. It is also possible to move out of the sound beam's path and hear nothing at all.
While the idea of sound beaming is not new, Noveto was the first to launch the technology.
According to the chief executive officer Christophe Ramstein, a “smaller” version of the device will be ready for release to consumers next year.

7 . Starman, the dummy(仿真人) riding a cherry-red Tesla Roadster(特斯拉敞篷车) through space, has made his closest approach ever to Mars. The electric roadster and its passenger were attached to the top of a Falcon Heavy rocket during the SpaceX rocket’s first test launch on 6 February 2018.
Two years later, the Falcon Heavy rocket and the vehicle at its tip are making their second trip around the Sun. Mr. McDowell, a Harvard astrophysicist, found that Starman passed 7.4 million kilometers from Mars at 06:25 GMT 7 October, 2020.
The closest recent approach between the Earth and Mars was 56 million kilometers in 2003, though the planets are often hundreds of millions of miles apart depending on where they are in their orbits. No one can see the Falcon Heavy rocket at its current distance, but orbits over periods of a few years are fairly straightforward to predict, and Mr. McDowell used data about how the rocket was moving when it left the Earth’s gravity behind to locate its recent movements exactly.
Last time Starman circled the Sun, McDowell said, it crossed Mars’ orbit while the Red Planet was quite far away. But this time the crossing lined up with a fairly close approach, though still not close enough to feel a strong tug from Mars.
At this point in time, if you were able to go look at the Roadster, it would probably look pretty different. The strong solar radiation environment between the planets would probably have destroyed all the exposed organic materials.
Without the Earth’s atmospheric and magnetic(磁场的) protection, even the plastics and carbon-fibre materials would start to break up. Over the course of decades or centuries, the car will end up with its aluminium(铝) frame and hard glass parts----that’s assuming that none of them get destroyed in impacts with passing space rocks.

8 . Every year, thousands of teenagers participate in programs at their local art museums. But do any of them remember their time at museum events later in life? A new report suggests that the answer is yes - and finds that alumni (毕业生)of arts-based museum programs credit them with changing the course of their lives, even years after the fact.
The Whitney Museum of American Art, the Walker Art Center and the Museum of Contemporary Art, Los Angeles recently asked researchers to conduct a study to find out how effective their long-standing teen art programs really are. They involved over 300 former participants of four programs for teens that have been in existence since the 1990s. Alumni, whose current ages range from 18 to 36, were invited to find out how they viewed their participation years after the fact.
Among the alumni surveyed, 75 percent of alumni rated die teen program experience as the most favorable impact on their own lives, beating family, school and their neighborhoods. Nearly 55 percent thought that it was one of the most important experiences they'd ever had, regardless of age and two-thirds said that they were often in situations where then experience in museums affected their actions or thoughts.
It turns out that participating in art programs also helps keep teens enthusiastic about arts even after they reach adulthood: 96 percent of participants had visited an art museum within the last two years, and 68 percent had visited an art museum five or more times within the last two years. Thirty-two percent of program alumni work in the arts as adults.
Though the study is the first of its kind to explore the impact of teen-specific art programs in museums, it reflects other research on the important benefits of engaging with the arts. A decade of surveys the National Endowment for the Arts found that childhood experience with the arts have linked arts education to everything from lower drop-out rates to improvement in critical thinking skills.

9 . Kyle Cassidy and three other members of the Annenberg Running Group were stretching on the grounds of the University of Pennsylvania, waiting for a few latecomers. The Penn colleagues and other community members meet three days a week for a roughly 30-minute jog and an occasional lecture. That's right― during some runs, one of them delivers a talk. Topics range from the brain to Bitcoin.
But on this day last January, it would not be their normal run. The first clue that something was off was the man who sprinted past them. "Running at an amazing pace," Cassidy told Runner's World admiringly. Cassidy discovered why the sprinter was so fleet of foot when another man ran by, yelling, “Help! He took my phone and laptop!"
At that, the group did what running clubs do: They ran, trailing the suspect down the streets of Philadelphia until he ducked into a construction site. The runners split up. Cassidy ran around to the far side of the site to cut the thief off while the others wandered the neighborhood hoping he had dumped the loot （赃物）in a backyard.
No luck. So they decided to ask residents whether they'd seen the guy. When they knocked on the door of one row house, they were in for a surprise. Unknown to them, he had already emerged from the construction site—and was hiding behind a bush by that very house. As the owner opened the door, the suspect darted out from behind the bush ... and right into the arms of campus police, who'd joined the chase shortly behind the runners.
The members of this running group are not hard-core athletes. But they do understand the benefit of a little exercise. ''Running is typically a useless sport where you turn fat cells into heat," Cassidy told The Philadelphia Inquirer. "But occasionally it can be useful, and here was one of those opportunities."

10 . Learning a second language is tricky at any age and it only gets tougher the longer you wait to open that dusty French book. Now, in a new study, scientists have pinpointed the exact age at which your chances of reaching fluency in a second language seem to plummet: 10.
The study, published in the journal Cognition, found that it’s “nearly impossible” for language learners to reach native-level fluency if they start learning a second tongue after 10. But that doesn’t seem to be because language skills go downhill. “It turns out you’re still learning fast. It’s just that you run out of time, because your ability to learn starts dropping at around 17 or 18 years old,” says study co-author Joshua Hartshorne, an assistant professor of psychology at Boston College.
Kids may be better than adults at learning new languages for many reasons. Children’s brains are more plastic than those of adults, meaning they’re better able to adapt and respond to new information. “All learning involves the brain changing,” Hartshorne says, “and children’s brains seem to be a lot more skilled at changing.”
Kids may also be more willing to try new things (and to potentially look foolish in the process) than adults are. Their comparatively new grasp on their native tongue may also be advantageous. Unlike adults, who tend to default (默认) to the rules and patterns of their first language, kids may be able to approach a new one with a blank slate (石板).
These findings may seem discouraging, but it was heartening for scientists to learn that the critical period for fluent language acquisition might be longer than they previously thought. Some scientists believed that the brief window closes shortly after birth, while others stretched it only to early adolescence. Compared to those estimates, 17 or 18 — when language learning ability starts to drop off — seems relatively old.
“People fared better when they learned by immersion (沉浸), rather than simply in a classroom. And moving to a place where your desired language is spoken is the best way to learn as an adult. If that’s not an option, you can mimic an immersive environment by finding ways to have conversations with native speakers in their own communities,” Hartshorne says. By doing so, it’s possible to become conversationally proficient — even without the advantage of a child’s brain.
