The sporty all-electric car from the Netherlands resembles a BMW coupe, but is unique: It captures more carbon than it emits.
“Our end goal is to create a more sustainable future,” said Jens Lahaije, finance manager for TU/ecomotive, the Eindhoven University of Technology student team that created the car.
Called ZEM, for zero emission mobility, the two-seater houses a Cleantron lithium-ion (锂离子) battery pack, and most of its parts are 3D-printed from recycled plastics, Lahaije said. The target is to minimize carbon dioxide emitted during the car’s full lifespan, from manufacturing to recycling, he added.
Battery electric vehicles emit virtually no CO2 during operation compared with fuel vehicles, but battery cell production can create so much pollution that it can take EVs (Electric Vehicles) tens of thousands of miles to achieve “carbon parity (相等)” with comparable fossil-fueled models.
“Direct air capture is a fairly new method of cleaning the air by capturing CO2 into a filter (过滤器). We have made use of this innovative technology and implemented this in our car. The idea is very simple: while we’re driving, air will move through our self-designed filters and the CO2 will be captured and stored.”
ZEM uses two filters that can capture up to 2 kilograms of CO2 over 20,000 miles of driving, the Eindhoven team estimated. They imagine a future when filters can be emptied at charging stations.
The students are showing their vehicle on a US promotional tour to universities and companies from the East Coast to Silicon Valley.

Known as SmartFarm, the small device designed by a team at the National University of Singapore, led by assistant professor Tan Swee Ching aimed to help address two of the world’s biggest problems — water shortage and food shortage. It’s a transparent (透明的) box that has vegetable plants growing in soil on the bottom — on top, a hydrogel (水凝胶) panel lies beneath a solar-powered motorized cover.
The hydrogel is very absorbent, readily drawing water vapor from the cool night air while the cover is open. An integrated timer closes it at daybreak, with the sun’s rays subsequently heating the hydrogel through the clear cover material. The gel responds by releasing its stored water in the form of vapor, which turns into liquid on the inside of the cover. When that cover periodically slides open throughout the day, the liquid gets wiped off along the inside edges of the box and runs into the soil.
According to scientists, the gel can absorb up to 300 times its weight in water at night. During the day, it releases that water at an hourly rate of 2.24 grams of water per gram of gel. And what’s more, the released water meets World Health Organization standards for drinkability.
Tan said, “The SmartFarm concept greatly reduces farms’ demand for water and is suitable for urban farming techniques such as rooftop farming. This is a significant step forward in easing water and food shortage.” He believes the SmartFarm device can be further improved with additional functionalities before it moves to mass and commercial production. For example, it can include wireless networking capability to enable users to monitor and control the process using smartphones.

【推荐2】Across the world, people and governments are banning pesticides (杀虫剂) and planting more flowers to increase bee populations naturally. Now farmers and beekeepers have a new way to protect bee populations.
The traditional hive most commonly used in the world today was designed by humans about 150 years ago. Most people are so used to them that they mistakenly confuse them with bees’ natural habitat. By completely redesigning the beehive, a company called Beewise was able to address many of the inefficiencies of the box and significantly improve bees’ well- being and lifetime.
Using 24/7 monitoring and smart technology that significantly increases pollination capacity (授粉能力) and honey production, Beewise’s robotic beehive, the Beehome, discovers threats to a honeybee population such as pesticides and the presence of pests and immediately defends against them. Its automatic robotic system responds to threats in real time and requires no human assistance. Beehomes are thermally regulated (热调节的) and can provide protection from fires, flooding, and Asian wasps. The hive even feeds the honeybees when local food supply is not available.
In a statement, the company says, “The Beehome reduces bee deaths by 80%, resulting in increased production of at least 50%, while reducing about 90% of manual labor (体力劳动) when compared to traditional beehives.”
Beewise currently manages more than seven billion bees, which is equal to 25,000 acres of pollinated crops. Through the Beehome device, the Israeli startup says it has saved over 160 million bees over the course of the last 12 months.
Their task of saving bees recently received $80 million funding for their autonomous hive. “We are using precision robotics with the world’s most creative technologies including AI and computer vision in order to save the bees,” stated Saar Safra, CEO of Beewise. He says that with thousands of orders placed in the U.S. in just the last few months, their new funding will allow Beewise to meet the market demand through increased production.

【推荐3】Schools in US are huge consumers of energy. According to ENERGY STAR, K- 12 schools spend more than $6 billion every year on energy, far more than the amount spent on other resources, and at least 30 percent of this energy is used inefficiently or needlessly.
Realizing that, some schools are seeking measures to save energy in several ways, from low-cost adjustments, such as turning off lights in unused rooms, to large-scale projects, such as turning to green equipment.
As solar energy is becoming a more financial choice for powering buildings, more schools are making the move toward the renewable energy and using solar panels(太阳能电池板)on their rooftops. According to an online solar marketplace EnergySage, schools have their strong points to use solar energy. They often have the kind of enough space, suitable locations that are perfect for setting up solar panels.
In September 2020, a nonprofit Generation180 released its third edition of a study on solar use in US schools. The findings showed that more than 7, 300, or 55 percent, of K- 12 public and private schools used solar energy, the number has increased by 81 percent since 2014.
They also described how solar schools were saving millions in energy bills, and provided several cases to show the increased savings achieved by solar-powered school districts. For ex- ample, an Arkansas school district used its every year's energy savings of nearly $100, 000 to increase its teachers' salaries.
The Interstate Renewable Energy Council, which tracks the number of K- 12 schools with solar equipment and helps schools go solar, says on its website that schools with solar setups have an opportunity to educate students about clean energy, and show them that they are de- voted to do something for students' and the planet's health and future.
Third-party ownership also makes funding for 79 percent of schools to use solar energy possible, meaning a majority of schools don't have to spend large amounts of money but can get the rewards of solar energy.

【推荐1】Can you imagine how great the United Kingdom is? The queen of Britain, Queen Elizabeth II, is also the queen of other 16 countries, including Australia, New Zealand, Canada and Jamaica. Her face is seen on stamps and coins all around the world.
Elizabeth Alexandra Mary Windsor was born in London on April 21st 1926. Her parents were George, the Duke of York, and Elizabeth, the daughter of the Earl and Count-ness of Strathmore. As a child, Princess Elizabeth lived with her parents and younger sister in London and Windsor. Every summer, she traveled to Scotland to visit her mother’s parents. She was interested in all sorts of sports, but her favorites were horse riding and swimming. She was also fond of acting, art and music.
As princess Elizabeth grew older, she started to play a part in British public life. When she was 14, she broadcast a radio message to all the children of Britain and the Common-wealth(共和国). Two years later, she carried out her first public engagement, and started to go on official tours shortly after that. After a tour to South Africa in 1946, she married Philip Mountbatten. The couple had four children: Prince Charles, born in 1948, Princess Anne, born in 1950, Prince Andrew, born in 1960 and Prince Edward, born in 1964.
After her father died, Princess Elizabeth became Queen Elizabeth II in a ceremony held in London in 1953. As a queen, she has many duties, and leads a very busy life. She travels throughout the world, meeting the leaders of other countries, and attends a large number of official functions. She also holds a meeting every week with the British Prime Minister. Every year, on Christmas Day, she broadcast a message to the people of British and the Commonwealth, talking about her hopes for the future.
Queen Elizabeth has been on the throne for more than 40 years and has become one of the most famous women in the world. Lots of people in British believe that she tries hard to understand her people and be a good queen. More than her title, this quality has earned her much love and respect.

【推荐2】A team of researchers spent weeks playing human-vs-rat hide-and-seek which was so much fun that the little rats laughed and jumped for joy.
The small players consisted of six adolescent male rats that were trained to play hide-and-seek against neuroscientist Annika Stefanie Reinhold. The researchers filled a room with hiding places made from different boxes. The little creatures learned that if they began the game inside a closed box, they wee the seekers while being in an open box meant they needed to hide. Soon, the rats became wise, figuring out that transparent boxes make the worst hiding places, and checking spots where their two-legged competitor had hidden before when seeking. The findings are reported in Science.
When they won, the rats were rewarded with tickling (挠痒) instead of food. " They chase our hand, we tickle them from the side, it's like how you play with small kittens or puppies," said co-author Konstantin Hartmann from the Humboldt University of Berlin.
Apart from playing for these interactions, the rats were motivated by the fun of the game. They would let out high-pitched laughter, suggesting they we in high spirits. If you’re wondering why you've never heard a rat laugh, their naughty giggles have to be picked up by scientific equipment as they are too high-pitched to be detected by the human ear. Even more adorably, the test subjects leapt in the air whenever they sniffed out a scientist. Yes,they jumped for joy. And even when the researchers offered food as an end-game reward, the rats postpone accepting them. They seem to want to keep playing the game.
Another sign that the rats were enjoying themselves was that they would often leap away to hide in a new location once they'd been found. Like children they wanted to keep playing again and again.
The team recorded nerve signals coming from the prefrontal cortex (前额皮质)of the rats' brains, an area involved in leaning. While research like this could tell us more about learn in the mammals, it could also help us better understand the importance of play. Future studies would look into the effects that not being allowed playtime might have on the brain, revealing how children and teenagers denied the opportunity to have fun and play with others might be affected.

【推荐3】Several months ago, I attended the opening event for a new children’s literacy (读写能力) campaign at the Burbank Library in California. The campaign is called Marvel Comics Close- Up, aimed at using comic books to encourage kids to read. Disney and Marvel donated 210,000 books to libraries and schools across the country.
Stars from Disney XD participated. They read Spider-Man comic books to 70 kids from Boys & Girls Clubs in southern California. The stars included Drake Bell (Ultimate Spider-Man), Dylan Riley Snyder (Kickin’ it), Olivia Holt (Kickin’ It) and Coie Jenson (Crash & Bernstein).
Drake Bell said that the Marvel reading campaign is aimed at kids who are bored with books, believing comic books are the answer for kids who say they’d rather play video games. “Comic books really get you into the story,” he told TFK(Time For Kids). “They are not just words or pictures on a page.”
Dylan Riley Snyder knows from his experiences that comic books have the power to inspire kids' imagination. His mom was a teacher and she used comic books to interest students who thought they weren't interested in reading. Dylan attended these classes. He would read the comic books and draw the characters along with the students. “It was a great way for these kids to start to enjoy reading,” Dylan said. “That’s how I got interested in reading too. Now I can share my love for comic books with others through the Marvel Comics Close-Up program.”
David Levine is the Vice President of Disney XD Worldwide. He said great stories and great characters, like Spider-Man and The Avengers, were key to making reading fun. “Reading can encourage you to explore new things and take you to all sorts of exciting places,” he told TFK.
