1 . Coca-Cola is to test a paper bottle as part of a longer-term goal to get rid of plastic from its packaging entirely. The prototype (样本) is made by a Danish company from an extra-strong paper shell that still contains a thin plastic liner (衬垫). But the goal is to create a 100% recyclable, plastic free botte capable of preventing gas escaping from carbonated (碳酸) drinks. The barrier must also ensure no fibers get into the liquid.
That may have a risk of changing the taste of the drink — or potentially can't meet the requirements of health and safety checks. But industry giants (巨头) are backing the plan. Coca-Cola, for example, has set a goal of producing zero waste by 2030. Coca-Cola was ranked the world's number one plastic polluter by charity group Break Free From Plastic last year, closely followed by other drink-producers Pepsi and Nestle.
The Paper Bottle Company, or Paboco, is the Danish firm behind the development of the paper-based container. Part of the challenge has been to create a structure capable of standing the forces exerted by carbonated drinks — such as cola and beer — which are bottled under pressure. On top of that, the paper needs to be mouldable to create distinct bottle shapes and sizes for different brands and take ink for printing their labels.
After more than seven years of lab work, the firm is now ready to host a trial in Hungary this summer of Coca-Cola's fruit drink Adez. Initially, this will involve 2,000 bottles distributed via a local retail chain.
But it is also working with others. Absolut, the vodka maker, is due to test 2,000 paper bottles of its own in the UK and Sweden of its pre-mixed, carbonated raspberry drink. And beer company Carlsberg is also building prototypes of a paper beer bottle.
Michael Michelsen, the firm's commercial manager, says the bottles are formed out of a single piece of paper-fiber-based material to give them strength.

2 . In recent years, Ethiopia has become a regional leader in solid waste management. Last year, the country transformed the landfill (垃圾填埋场) in Addis Ababa into a new waste-to-energy plant, the first such project on the continent. The plant incinerates up to 1, 400 tonnes of waste every day, about 80 percent of the city's rubbish, supplying the capital with 25 percent of its household electricity needs.
However, despite these important steps, challenges remain in Ethiopia. Although the country has permitted the Basel, Stockholm and Rotterdam conventions, laws and policies for environmentally sound management of hazardous (有害的) wastes are still not effective in pre- venting littering waste illegally.
To help Ethiopia meet these challenges, the Chemicals and Waste Management Program is supporting the country with a three-year project to enhance its capacity for sound management of hazardous wastes.
In the initial stages, a project management unit will be formed, made up of many representatives from government departments and private organizations. This unit will be responsible for reviewing and assessing Ethiopia's current legal system, which, despite numerous advances in recent years, does not specifically target the recycling of hazardous waste. Once legal gaps are identified, the project will seek to update existing policies and strategies.
Many people in Ethiopia are not aware of the possible effect of environmental damage and the need to report such crimes to the police. To resolve this pressing issue, Ethiopia will be conducting a series of capacity-building activities, including creating awareness-raising programs, training trainers and providing equipment.
Ethiopia will also work to establish a national mechanism for chemicals and waste management by engaging government departments and civil society groups. Authorities will also make budgetary provisions (预算拨款) in national, regional and institutional planning to ensure funding for these activities is sustainable even after the project's completion.

3 . A new study has found that animals feign（假装）death for long periods of time in order to escape capture from their predators. How long they are motionless depends on the circumstances, but they can wait out their predators for quite a long time when their lives are in danger.
Animals stay still to avoid capture for different lengths of time. “Most intriguingly, Charles Darwin recorded a beetle that remained motionless for 23 minutes. Antlions, our favorite study creature in this regard, set a record of 61 minutes,” says lead author Nigel R. Franks from the University of Bristol.
Antlions are members of large group of insects. Antlion larvae（幼虫）dig pits in loose soil and then aggressively attack ants and other small insects that fall into the sandy pits. In another study, researchers dug sandpits to understand the physics of how antlion larvae build their pits. As part of their research they needed to weigh the individual larvae. When they put them onto the microbalance scale to weigh them, they noticed that the larvae remained motionless for long periods of time. “This made it ‘piece of cake’ to weigh them but it aroused researchers’ curiosity, ‘What on earth were they playing at?’” Franks says.
The researchers found that the amount of time the antlions remained stationary after being disturbed was unpredictable and was often quite lengthy. In researching other animals, they found that how long they wait to move again can depend on factors such as hunger and temperature, but it always varies.
This unpredictability is absolutely crucial for their survival, Franks says. For example, if a bird visits these antlion pits and the larvae “play dead”. the birds will fly around the antlions to see if they move. “Imagine if antlions always remained immobile for 5 minutes. In such case, the predator could look for alternate prey（猎物）and then return to its original one when the time is up,” he says. “If that happened, it would be a short life for the predictable death-feigner.” But because the time is unpredictable, the birds leave and go find something else to eat. The predators turn their attention from the unmoving prey that no longer catches their eye to something nearby that is a better alternative.

4 . When he was two years old, Ben stopped seeing out of his left eye. His mother took him to the doctor and soon discovered he had cancer in both eyes. After possible treatments failed, doctors removed both his eyes. For Ben, vision was gone forever.
But by the time he was seven years old, he had developed a technique for feeling the world around him: he clicked with his mouth and listened for the returning echoes. This method enabled Ben to determine the locations of open doorways, people, parked cars, garbage cans, and so on. He was echolocating: bouncing his sound waves off objects in the environment and catching the reflections to build a mental model of his surroundings.
Echolocation may sound like an improbable feat for a human, but thousands of blind people have perfected this skill, just like Ben did. The event has been written about since at least the 1940s, when the word ''echolocation" was first invented in a science article titled “Echolocation by Blind Men , Bats, and Radar.”
How could blindness give rise to the amazing ability to understand the surroundings with one's ears? The answer lies in a gift on the brain; huge adaptability.
Mother Nature filled our brains with flexibility to adapt to circumstances. Just as sharp teeth and fast legs are useful for survival, so is the brain's ability to reset, which allows for learning, memory, and die ability to develop new skills.
In Ben's case, his brain's flexible wiring repurposed his visual cortex for processing sound. As a result, Ben had more neurons available to deal with listening information, and this increased processing power allowed Ben to interpret soundwaves in shocking detail. Ben's super-hearing proves a more general rule: the more brain area a particular sense has, the better it performs.

5 . Honeybees can’t swim, and when their wings are wet, they can’t fly, either. But Chris Roh and other researchers at the California Institute of Technology found that when bees drop into bodies of water, they can use their wings to produce little waves and slide toward land-like surfers who create and then ride their own waves.
As with many scientific advances-Isaac Newton’s apple or Benjamin Franklin’s lightning bolt-Dr. Roh’s experiment began with a walk. Passing Caltech’s Millikan Pond in 2016, he observed a bee on the water’s surface producing waves. He wondered how an insect known for flight could push itself through water.
Dr. Roh and his co-worker, Morteza Gharib, used butterfly nets to collect local Pasadena honeybees and observed their surf-like movements. The researchers used a wire to restrict each bee’s bodily movement, allowing close examination of their wings. They found that the bee bends its wings at a 30-degree angle, pulling up water and producing a forward force. Bees get trapped on the surface because water is roughly three times heavier than air. But that weight helps to push the bee forward when its wings move quickly up and down. It’s a tough exercise for the bees, which the researchers guess could handle about 10 minutes of the activity.
The researchers said the surf-like movement hasn’t been documented in other insects and most semiaquatic insects use their legs for propulsion, which is known as water-walking. It may have evolved in bees, they-predicted.
Dr. Roh and Dr. Gharib have imagined many practical applications for bees’ surfing. One plan is to use their observations to design robots able to travel across sky and sea. “This could be useful for search and rescues, or for getting samples of the surface of the ocean, if you can’t send a boat or helicopter,” Dr. Gharib said.

6 . Perhaps thousands of people have searched for a bronze chest full of gold and jewels hidden in the Rocky Mountains between Santa Fe and the Canadian border hidden by a millionaire adventurer. At least four people died in their search for the treasure.
But it's all over now. Fenn's Treasure has been found. The 89-year-old adventurer named Forrest Fenn, who created the treasure hunt, announced the news via his website. “I don't know the person who found it, but the poem in my book led him to the precise spot,” Fenn wrote. “The treasure was confirmed by a photograph the lucky finder sent me.”
Forrest Fenn, the man who started the hunt, lives in Santa Fe. He was a pilot in the Vietnam War and later accumulated his wealth as a dealer in art and antiques. Fenn was diagnosed(诊断) with cancer in 1988 and had planned to die peacefully in the woods with his treasure. But when his cancer became less serious, he changed his plan, eventually writing the poem that described his dream resting place, which is where he hid the treasure. The poem appeared in a memoir called The Thrill of the Chase. Fenn said that the chest wouldn't be found by accident; only a treasure hunter who correctly interpreted the clues(线索) would find it.
Several treasure hunters went missing while attempting to find the chest, including hunter Jeff Murphy and Mike Petersen, both of whom went missing in Yellowstone National Park in 2017. Fenn said that he had never been to the Yellowstone National Park, and that the treasure was not in a dangerous place. "It was in the thick forest of the Rocky Mountains and had not been moved from the spot where I hid it more than 10 years ago," Fenn wrote on his website. It is illegal to remove anything from a national park, which would cause trouble in legally claiming the treasure if it was found there.

7 . Vincent Van Gogh, for whom color was the most important form of expression, was born in Holland in 1853. Brought up in a religious and cultured atmosphere, Van Gogh was highly emotional and lacked self-confidence. Between 1860 and 1880, when he finally decided to become an artist, Van Gogh had worked unsuccessfully as a clerk in a bookstore and an art salesman. He remained in Belgium to study art, determined to give happiness by creating beauty. One of his famous paintings is The Potato Eaters (1885)．
In 1886, he went to Paris to join his brother Théo. In Paris, Van Gogh studied with Cormon, later met Pissarro, Monet, and Gauguin, and began to lighten his very dark palette(调色板)．His nervous temperament made him a difficult companion and night-long discussions combined with painting all day undermined his health. He decided to go south to Arles where he hoped his friends would join him and help found a school of art. Gauguin did join him but with bad results. Near the end of 1888, an incident led Gauguin to finally leave Arles. Van Gogh ran after him with an open razor, was stopped by Gauguin, but ended up cutting a part of his own ear off. Van Gogh then was sent to a mental (精神的) hospital for treatment.
In May of 1890, he seemed much better and went to live in Auvers-sur-Oise under the watchful eye of Dr Cachet. Two months later he was dead, having shot himself “for the good of all”．During his brief career he had sold one painting. Van Goghˈs finest works were produced in less than three years. His great fusion (融合) of form and content is powerful, dramatic and emotional, for the artist was completely absorbed in the effort to explain either his struggle against madness or his comprehension of the spiritual essence (精华) of man and nature.

8 . Handwashing is one of the easiest ways to protect against disease, but lack of running water is a problem for 3 billion people in the world, according to the World Health Organization(WHO) and UNICEF, the United Nations Children's Fund. Tippy taps are one way. Sometimes, the little things make such a big difference. These low-cost handwashing stations are helping people stay healthy.
There are different ways to build and use tippy taps. But the basic tools include a plastic water bottle, sticks, and rope. Hang the bottle from a branch or pole. Press a foot pedal to tip the bottle and release water. Then wet your hands and scrub with soap for at least 20 seconds. Done!
In Uganda, Faridah Luanda has been teaching her neighbors how to make tippy laps. Washing hands is very difficult in her neighborhood because they don't have access to washing facilities. When COVID-19 started and people were told to clean their hands frequently, they needed to be creative. Luanda and her neighbors have set up 800 tippy taps in the community. “We are helping ourselves,” Luanda says “Children, people with disabilities, and other vulnerable people—they cannot be left behind.”
In Guatemala, people have set up nearly 400 tippy laps. Each cost about $12 to make.
Tippy taps are also being used in the United States. Kids from the Lake & Park School, in Seattle Washington, heard about the project. They raised $4,000 to support it. In Tucson, Arizona, they' re helping the homeless. Two were set up at a shelter called Sister Jose Women’s Center. COVID-19 forced the shelter to close. But workers continued to give out food. They needed a way to let people wash their hands before eating. The tippy tap is such a simple solution.

9 . The idea of using a public bathroom with see through walls may sound like the stuff of nightmares. But a famous Japanese is hoping to change that view, using new technology to make restrooms in Tokyo parks more inviting.
“There are two things we worry about when entering a public restroom, especially those cated at a park,” according to architect Shigeru Ban’s firm. “The first is cleanliness, and the second is whether anyone is inside.”
The newly-invented transparent walls can turn off both of those worries, Ban says, by showing people what awaits them inside. After users enter the restroom and lock the door, the room’s walls turn a powdery paste) shade and are no longer see-through.
Ban’s are sure to make for great conversation among visitors to the park-and they’ll stand out even more after dark. “At night, the facility lights up the park like a beautiful lantern,” the architect’s website says.
The group is behind the Tokyo Toilet project, world-famous architects to create toilets “like you’ve never seen. The project’s eye catching toilets are part of a plan to put people ar ease when isiting a public bathroom. The project may seem silly, but the 16 architects who are reimagining public toilets are some of the brightest names in Japanese architecture. The list includes four Pritzker Prize winners-Ban, Toyo Ito, Tadao Ando and Fumihiko Maki-along with international stars such as Kengo Kuma and Sou Fujimoto. The fashion designer Nigo is also contributing.
Ban’s colorful public bathrooms opened to the public this month in two parks: Yoyogi Fukamachi Mini Park and Haru-no-Ogawa Community Park. Other bespoke commodes will be opening in coming months.

10 . Gerardo Ixcoy is a 27-year-old teacher in Guatemala. He teaches in the area where having electricity is something of a luxury（奢侈品）and students have no access to mobile apps or computers, which became a problem when Guatemalan government had to choose distance education for students at home because of COVID-19.
Gerardo Ixcoy felt that he had to teach those children living far from the digital world. After all, education is a universal right and Gerardo Ixcoy thought those children shouldn't be excluded from having the education they needed. There had to be an alternative to distance education. But what was the solution?
Gerardo bought himself a secondhand tricycle（三轮车）with his savings. Once he had the tricycle, the next step was to change it into a classroom on wheels. He put a roof with a solar panel（太阳能电池板）on it, along with a screen to avoid the spread of COVID-19. He fixed a whiteboard on it so he could explain to the students the basics of primary education： math, the local language and the universal national language—Spanish.
The purpose of the solar panel is to provide constant power for a small loudspeaker so he can teach from a distance. It's a matter of respecting the healthy distance required to be safe from the virus. He, the teacher, stays outside, and the student participates from his or her house.
With that enthusiasm for education, he tries to visit his students at least twice a week, riding his classroom-cycle. The children he serves say that, although he visits them for only a few hours a week, they look forward to it. They appreciate his visit and will take advantage of it to learn.
