Engineers in Upstate New York have invented a folded paper device that looks like a decorated art project. But don't be fooled. This is actually a paper-based battery. No, it doesn't look like any of those metal batteries running flashlights or smartphones. In these systems, the battery can be printed on a page. The battery 's power consists of living bacteria.
Paper electronics are simple to make and inexpensive, notes study leader Seokheun Choi, an engineer at Binghamton University. They need no electrical outlet to recharge. They just need more bacteria, which can be found everywhere — including dirty water.
“ Most batteries use chemicals to generate electricity. Substituting bacteria can be an advantage,” Choi says.“They are cheap and self-repairing.” What paper-based batteries won't do is generate much power. They do, however create enough to run small devices in faraway or dangerous places — such as a battlefield . They might also find use in medicine . For instance, they might power tiny sensors, such as the types used to measure blood sugar.
This invention is based on an observation made more than a century ago — that microbes (微生 物) produce electricity as they digest food. Scientists refer to the bio-batteries based on this principle as microbial fuel cells. A fuel cell generates electricity like a regular battery. But a regular battery stops producing electricity when its inner chemical reactions stop. A fuel cell uses fuel that can be refilled. In this case, bacteria serve as the fuel. By refilling more microbes, as needed, scientists can keep these fuel cells running.
Lab tests have shown that the new battery can produce a current. Now, Choi and his team are looking at ways to increase the power. They're studying different shapes and materials for the anode and cathode (正负 极). They're also looking for the best ways to combine batteries for more power. The beauty of the paper devices is that you can simply fold them to connect them. And they surely will be a trend in the near future.

【推荐1】Loud cheers and applause broke out at NASA’s Jet Propulsion Lab on Monday, November 25, 2018, as the unmanned lander, called Insight, touched down on Mars, after nearly seven
years from design to launch to landing.The great arrival of the spacecraft—designed to listen for quakes and shakes as a way to discover the Red Planet’s inner secrets, how it formed billions of years ago and, how other planets like Earth took shape—marked the eighth successful landing on Mars in Nasa’s history.
Minutes after InSight landed on the surface of Mars, the first image was sent back, showing a wide flat area as seen through a dirty camera.The touchdown came after a nearly seven-month, 300 million-mile travel from Earth to Mars, during which the InSight spacecraft had to slow down from a speed of more than 12,000 mph. The spacecraft’s heat shelter helped the lander survive temperatures as high as 2,700℉.
Each step along the way was watched nervously at JPL, with updates delayed by the eight-minute light travel time between Earth and Mars. Mission controllers hugged each other with joy when the signals were received. “We are proud of everything that has gone on today,” they told us reporters.
The first picture of the surface of Mars was sent back to Earth by one of the MarCO nanosatellites (马可纳米卫星) that accompanied InSight during its travel to Mars. The dust from the landing made the view unclear. Pictures from it were expected to be clearer once the dust settled and the lens cover (镜头盖) was removed.
Hours later, InSight’s batteries were charging as expected. The InSight team also passed on another picture, taken by a different camera that’s fixed on the lander’s robotic arm. The view is clearer, showing the robotic arm and the seismometer, which is used to discover the actual movement of the ground.

【推荐2】For centuries, humans have explored the Earth’s mountains, jungles and deserts. But despite covering more than 70% of the Earth’s surface, the ocean is still a relative mystery. In fact, just over 20% of the ocean bed has been mapped. Getting a fuller picture would enable us to guide ships more safely, build wind-farms and protect ocean species—all part of what’s known as the “blue economy”, projected to be worth $3 trilling by 2030.
Underwater robotic vehicles are helping gather that data quicker and more cheaply than ever before. But many of these vehicles depend on batteries which need to return to a boat or the shore to recharge, making it difficult to map more remote (遥远的) parts of the sea.
A startup called Seatrec is rising to the challenge, founded by oceanographer Yi Chao. Yi Chao developed technology to power ocean robots by taking advantage of “the naturally temperature difference” between colder and warmer parts of the sea, which in turn creates energy and powers the robot’s generator (发电机). They get charged by the sea, so their lifetime will be almost limitless,” Chao said.
The power module (组件) can be fixed on existing data-gathering robots which dive a kilometer down to examine the chemistry and shape of the seabed, creating a map of the surrounding area. The robot returns to the surface to send back its findings via satellite. A basic power module costs as much as $20,000. But the access to free, renewable energy and the ability to stay in the water longer make data gathering up to five times cheaper in the long run.
Started in 2017, the Seabed 2030 Project has increased awareness about the importance of the ocean floor and given researchers and companies a clear goal to work towards: map the entire seafloor by the end of this decade.

【推荐3】Animals can be reproduced by technology now; researchers can clone them. A clone is an exact copy of another animal or plant. Scientists have cloned a sheep which they have named Dolly. Researchers took genes from a ewe (母羊) and used them to create a copy (Dolly) of the ewe.
Why are scientists doing this research? One reason is to get information about genes so they can improve our health. They also want to learn how better farm animals can be produced. Cloning is a controversial issue for people. Some people think it is good because this research can help us, but other people think cloning is unacceptable. Some people think it might be possible to save endangered animals by cloning them. Tigers, elephants, and other endangered animals might be saved in this way.
In China, pandas are endangered because they are hunted and they are losing their habitat, so some Chinese scientists want to try to clone pandas to save them from extinction.
I don’t really like the idea of cloning animals, but I don’t think I want panda to become extinct. If the best way to save them is to make cloned pandas, they must be cloned.
I want to live with a lot of animals and nature. I don’t want animals to die out, especially pandas. I think humans must think more about protecting animals and nature. Maybe cloning is the way to save all endangered animals.

【推荐1】Social media provides materialists with ideal opportunities to compare themselves with others, which makes them subject to passive and addictive user behavior. This stresses them out and, ultimately, leads to low life satisfaction, according to a new study.
The researchers headed by Dr. Phillip Ozimek from Germany employed 1, 230 people for their online survey. In order to participate, respondents had to visit at least one social media channel at least once a week. On average, the participants stated they spent just over two hours a day on social media.
The team used six different questionnaires to determine the extent to which the participants had a materialistic attitude and tended to compare themselves with others, whether they used social media more actively or passively, whether they were addicted to social media, how stressed and how satisfied they were with their lives.
“The data showed a stronger materialistic approach goes hand in hand with a tendency to compare oneself with others,” points out Ozimek. This comparison is easy to make on social media, primarily through passive use—by looking at the content posted by other users. Materialism and passive use were also linked to addictive use of social media.
“Users are constantly thinking about the respective channels and fear they’re missing out on something if they aren’t online,” explains Ozimek. “This in turn leads to poorer mental health like stress. The final link in the chain is reduced life satisfaction.”
“Overall, the study provides further evidence that the use of social media is associated with risks, especially for people with a highly materialistic mindset,” says the psychologist. “This is particularly worrying, because social media can stimulate and increase materialistic values through influence r marketing. Meanwhile, the platforms attract materialists anyway, as they’re a perfect way to satisfy materialistic needs.”
“It’s definitely a good idea to be aware of the amount of time you spend on social media and to reduce it,” recommends Ozimek, who advises against giving up social media completely. “If you did, you’re likely to over-correct.” He also suggests recording materialism and social media use in patients undergoing treatment for mental health disorders. “While these factors are often irrelevant, they can be a starting point for additional interventions patients can try out at home.”

【推荐2】Farmers and hunters are calling for an extension (延期) to the Victorian duck hunting season, saying certain species are doing great harm to crops and waterways and need to be controlled. This season runs from 8:00 am today and will end in 20 days, down from the usual 12 weeks, with a bag limit of five listed game ducks per day.
Wayne Shields grows leafy greens on the Mornington Peninsula and he said the decision to reduce the duck hunting season would take its toll on farmers. “The wood ducks are the ones causing all of the damage; the black ducks are no problem around here. The wood ducks come in at night and they just clean me out completely and they’ve done it a number of times over a number of years,” he said.
Mr. Shields and his wife, Natasha, run Peninsula Fresh Organics and he said there was nothing he could do to stop the invasion (入侵). “I nearly went broke a few years ago. Back then I was planting 10,000 lettuce (生菜) a week and they would quite happily eat 10,000 lettuce a week.” Due to the damage caused by the wood ducks, Mr. Shields said there should be a year-round open season on the wood ducks and farmers should be allowed to shoot birds.
Professor Richard Kingsford, Director of the Centre for Ecosystem Science at UNSW, said although the wood ducks ate crops, extending the duck season may not achieve what farmers wanted. He is calling on the government to invest more in research to address the threat certain species of waterbirds caused for some farmers, so other nonlethal (非致命的) ways to destroy the birds can be found.

【推荐3】Americans love their automobiles. So long, it seems, as they don’t run on batteries. A survey published in July by the Pew Research Centre found that less than two-fifths of them would consider buying an electric vehicle (EV). Despite expanding charging networks and more EV models to choose from, that is a slightly lower share than the year before.
The biggest block to EV enthusiasm in America is price. The average EV there sells for $52,000, estimates Cox Automotive, a consultancy. That is not a world away from the $48,000 that Americans typically pay for a petrol vehicle. But total costs of ownership, which combine the sales price and running costs for five years, vary more widely. At $65,000, the typical EV is $9,000 more expensive to own than a petrol car (owing to factors like pricey home chargers, dearer insurance and, compared with Europe and China, inexpensive petrol).
All this leaves America’s car industry circling a roundabout. Consumers’ unwillingness to pay for expensive EVs is forcing carmakers to take action to shift stock (库存). Tesla has cut its prices several times in the past year. Carmakers are offering average discounts of almost 10% on their EVs, more than twice as generous as for petrol cars. But this is making it even harder for the companies to make money from battery power. Continued losses in turn may make car firms lose appetite to invest in a broader electric offering that would appeal to buyers.
American carmakers are still hoping they can escape this vicious (恶性的) circle. They are mostly postponing their American EV investments rather than pulling the plug on them. And from January the EV tax credits (免税) will also be available at the point of sale, making it less burdensome for buyers to take advantage of them. All this could eventually generate profits for car firms. Eventually may, though, come a bit later than hoped.

【推荐1】The Manneken Pis is one of Brussels’ most popular tourist attractions. It has been peeing (撒尿) fresh water into a fountain in the Belgian capital since the 17th century. Now, the peeing boy has finally become environmentally friendly.
To everyone’s surprise, the famous statue used to waste 1,000 to 2,500 liters of drinking water a day. He peed water directly into the city’s sewers (下水道).
Energy engineer Regis Callens found this waste after fixing a water meter (水量计) in the statue. If his calculation is correct, then the peeing boy has wasted more than 250 million liters of water over the last 400 years.
As a result of this finding, a new system for delivering the water back to the naughty boy was created. Now he will no longer waste clean drinking water. Instead, he will use water recycled from a closed circuit (闭合回路). That means the water he pees out will be used again in an almost endless cycle.
The solution came out during the Brussels Water Week. A local official said, “We will also set up the system in schools and sports centers. We should set an example. We will encourage everyone in Brussels to pay attention to their water consumption.”
The Manneken Pis is a copy of the 1619 original, which is in a nearby museum. He is often dressed up in different costumes throughout the year to celebrate festivals and special events.

【推荐2】After a lot of local and state warnings, research and bans of hoverboards (平衡车), the federal government issued a statement on Wednesday. The message: Many of the machines are a major fire risk.
The Consumer Product Safety Commission (CPSC) announced the recall (召回) of more than a half-million hoverboards.The safety commission said that the battery-powered machines had been the cause of at least 60 fires. The announcement affects 10 companies that make or sell the products, including Razor and Swagway, two of the leading manufacturers.
Hoverboards, which do not actually hover or fly, have been the subject of regulatory examination in recent years. Officials have banned them from airplanes and sidewalks, and the safety commission carried out research last fall because of reports of fires and explosions.
The risk of fires from the machine's electrical system and battery(电池) pack has attracted the most attention from the safety commission, which says it will now turn its focus toward the risk of falls and other accidents. The agency is worried that flaws (缺陷) in the board's design could lead riders to lose their balance.
There is no federal safety standard specific to hoverboards. Underwriters Laboratories (UL), a standards-setting and testing organization, came up with voluntary electrical requirements for self-balancing hoverboards as a result of the safety commission's research, said Elliot F. Kaye, the chairman of the CPSC.
He required consumers to return any hoverboard that did not reach the standards set by the company. However, part of the problem, he explained, was that many hoverboards had been sold by temporary stands such as those in malls or college campuses — fly-by-night sellers that can be harder to track down or get in touch with. “That is a deeply frustrating aspect of it,” Mr. Kaye said. “Somebody can just put up a stand, order some products, disappear, and there's nobody there to take responsibility when things go wrong.”
1. Why will so many hoverboards be recalled?A.They aren't easy to use. | B.They are likely to cause fires. |
C.They don't actually hover or fly. | D.They caused many traffic accidents. |

【推荐3】It’s said that every Irish “mammy” has her own way to cook Irish stew(炖菜). Simple but satisfying, it has fed the poor over centuries, which makes it a national dish.
The ingredients tell the story. First up, there’s the “spud”, as the Irish call the potato. First brought to Ireland in the 16th century, it was an unbelievable food, providing bumper crops that could be stored over the cold winter months. Soon, everyone was eating it — for breakfast, lunch and tea.
With the arrival of the spud, the population increased from one million to eight million in less than three centuries. But this dependence on the vegetable would prove disastrous when crops were struck by disease in the 1840s. The great famine(饥荒)that followed killed over a million people — and forced millions more to run to other countries. It’s hard to believe that during the years of famine, Ireland continued to export huge quantities of food to Great Britain, its colonial master at the time.
Today, Ireland is an independent nation. Nobody thinks about the potato famine as they enjoy their Irish stew but there’s a bone-deep awareness of the country’s long connection with the spud.
Potatoes are all well and good, but the stew gets its taste from the meat. It used to be made with mutton as it was the only meat available to the poor. However, the only way to make it good enough to eat was to stew it in the pot for hours.
Today, most people use lamb. However, this remains slightly traditional among purists, who also criticize(批评)the addition of ingredients like carrots, parsnips, thyme and supermarket-bought materials.

【推荐1】Upskilling is the future—but it must work for everyone
Automation and job replacement will be one of the most significant challenges for the global economy of the coming decades. A 2017 Mckinsey report established that 375 million workers will need to switch occupational categories by 2030. The World Economic Forum suggests that by 2022, automation will replace 75 million jobs globally—but create 133 million new ones.
Research into the likelihood that a job will be impacted by digitization has largely focused on the “automatability” of the role and the following economic regional and political effects of this. What this research doesn’t take into account is something more important for the millions of taxi drivers and retail workers across the globe: their likelihood of being able to change to another job that isn’t automatable. Recent research suggests that the answer to this may be that the skills that enable workers to move up the ladder to more complex roles within their current areas might be less important than broader skills that will enable workers to change across divisions.
In July, Amazon announced that it would spend $700 million retraining around 30% of its 300,000 US workforce. While praiseworthy, it will be interesting to see the outcome. In the UK, the National Retraining Scheme has largely been led by employers, meaning that those on zero-hours contracts and part-time workers—often low-skilled—will miss out. Governance will be a crucial element of ensuring that such schemes focus on individuals and life-long learning, rather than upskilling workers into roles that will soon also face automation.
According to the Mckinsey report, “growing awareness of the scale of the task ahead has yet to translate into action. Public spending on labour-force training and support has fallen for years in most member countries of the Organisation for Economic Co-Operation and Development,” which impacts more than just the low-skilled and poorly compensated.
The global impact of automation is also put into relief by research demonstrating that, between 1988 and 2015, income inequality increased throughout the world. Billions of people do not have the essentials of life as defined by the UN Sustainable Development goals.
Alongside climate change, automation is arguably tech’s biggest challenge. As with globalization, governments and employers—and us workers—ignore its potential consequences at risk to ourselves.

Mother’s Day was proclaimed a day for national observance by President Woodrow Wilson in 1915. Ann Jarvis from Grafton, West Virginia, had started the idea to have a day to honor mothers. She was the one who chose the second Sunday in May and also began the custom of wearing a carnation.
In 1909, Mrs. Dodd from Spokane, Washington, thought of the idea of a day to honor fathers. She wanted to honor her own father, William Smart. After her mother died, he had the responsibility of raising a family of five sons and a daughter. In 1910, the first Father’s Day was observed in Spokane. Senator Margaret Chase Smith helped to establish Father’s Day as a national commemorative day, in 1972.
These days are set aside to show love and respect for parents. They raise their children and educate them to be responsible citizens. They give love and care.
These two special days are celebrated in many different ways. On Mother’s Day people wear carnations. A red one symbolizes a living mother. A white one shows that the mother is dead.Many people attend religious services to honor parents. It is also a day when people whose parents are dead visit the cemetery. On these days families get together at home, as well as in restaurants. They often have outdoor barbecues for Father’s Day. These are days of fun and good feelings and memories.

【推荐3】Arguster grew up on his family’s farm in a remote village. Planting cash crop — cotton, they were breaking even and had to make ends meet. In his childhood, there were nine kids at home. All the boys were in one room with two beds. Two slept at the head while two slept at the foot. Therefore, there was one thing about their feet — washing them before crowding onto the bed.
When there was a hole in Arguster’s jeans, his mother would put a patch on it. However, the hole kept going. It was the naughty kids, Arguster included, that took the jeans out, hung them on a line and shot them to put holes. Aware of that, however, Ben, the father, didn’t rebuke them, knowing it might be the only way to bring laughter to his kids.
Arguster’s first lesson in economics was taught by Ben. The childish kid had worked and made a little extra money. He couldn’t help admiring himself, “I make six dollars! Six dollars! Man! I’m on the top of the world!” With a great thrill, Arguster decided to go to fair, where he played games, ate cotton candy... When asked by Ben how much he had spent, with his head down, Arguster replied, “Daddy, I spent it all...” Looking at his messy hair, Ben sighed, “Boy, you spent all your money and haircut’s gone up to 75 cents. I’m afraid...” From then on, Arguster always kept enough money to get himself a haircut.
Ben taught his kids how to do the right thing and wanted them to do the right thing, which Ben tried to pass on to his kids, in his own way. Ben started a syrup mill(糖坊). People in the community brought their cane and millet for Ben to grind up (磨碎) for syrup. When people paid with buckets of syrup, Ben refused. Arguster got confused, “Daddy, why don’t you let these people pay you?”
“Because we got enough syrup to last for a long time! Son, these people don’t have money to pay. That’s the only way they can pay.”
