1 . An impressive invention made by a 17-year-old teenager, called Anna Du, is helping to clean up small pieces of plastic from the ocean.
While walking along her local beaches in Massachusetts, the young student began collecting waste plastic bags and bottles. But what she noticed was a large number of tiny pieces of plastic or microplastics that were impossible to pick up. At just 12 years old, Du set out to solve the problem. After testing a few prototypes(原型)in her backyard, she invented a remotely operated vehicle that uses the infrared camera(红外摄像机)to detect microplastics on the ocean floor. More recently, Du has also created a simulation(模拟)model that uses artificial intelligence to predict where microplastics are located.
Du’s robot invention has earned her awards at top science fairs in the US, and she’s now a nationally recognized advocate for microplastic awareness and pollution prevention. “When I first started doing science fairs, I had no idea that a young girl without lots of money and just a little advanced engineering knowledge could make a difference in the world. I’ve learned that I truly love working on a problem that’s so much larger than me,” Du said.
Du has also released a new book to help spread the word not only about the dangers of microplastics but also about the ways to relieve the problem. Titled Microplastics &Me, the book follows Du’s own story of how she went from worrying about the environment to designing award-winning solutions. Writing for kids her own age, the young girl alerts her readers to the threat of microplastic pollution and urges them to care about the environment. The book hopes to encourage young students to get into science, technology, engineering and math(STEM)subjects and to inspire a new generation of inventors and engineers. What’s more, Du has even raised more than $7,000 to distribute the book free to kids and libraries in high-need communities.

2 . Slobodchikoff, a biologist who has spent years working to better understand the calls of dogs, used that knowledge to help people who were having trouble with their pets.
A man reported his dog wanted to bite him. So Slobodchikoff went to the man’s house. He watched as the owner walked over to the dog, towered over the pet and then said, “Good dog!” in a low-pitched(音高) voice. “The dog ran into a corner,” Slobodchikoff recalled. The owner had scared the dog. Slobodchikoff recommended that the man should do the opposite. The owner took that advice—and ended up developing a great relationship with his pet.
Not everyone has the time to study dog communications or the money to bring in an expert. Slobodchikoff thinks tech could help. He thinks a cell phone app or device that you could point at a dog. This would record video and audio(音频) of a dog’s behavior and then upload it.An artificial intelligence(AI)system would later analyze it.
The AI “ would translate this for you into English or any other language,” says Slobodchikoff. The result, he explains, may be something like “‘I’m hungry’ or ‘I need to go outside to pee’ or ‘I want to go for a walk.’”
To train the AI system, Slobodchikoff planned to get data directly from pet dogs, but for some reason, he hasn’t yet restarted the project to date, but hopes to soon.
Search an app store for a pet translator and you’ll find plenty. Some are completely unscientific and silly. MeowTalk, however, is a cat-translation app based on an AI model. In 2021, its creators reported that the AI model achieved 90 percent accuracy at identifying nine different emotional states in meows. These included angry, happy, hunting, pain and rest. The app picks conversational phrases based on these emotions, like “nice to see you,” or “let me rest.”
People who have tried the app say it doesn’t always work well. But better translations of barks and meows may be just around the corner.

3 . Washing machines are one of the greatest inventions of the last few centuries.They have made life easier. Unfortunately, washing machines also contribute to the environmental issues of energy use and micro-plastics flowing into the oceans. That is why the washing machine manufacturer (制造商), Samsung, and the outdoor-wear company, Patagonia, are working together to make a change.
For Patagonia, the issue of micro-plastics has been on its mind for years — its woolen jackets release many microfibers. As for Samsung, new requirements throughout the world have forced many producers to start thinking about ways to help reduce the number of micro-plastics. There are currently more than 14 million tons of micro-plastics floating in the oceans. Though people previously think of things such as plastic bottles and fishing lines when it comes to plastics in the ocean, thousands of micro-plastics are released into seas with every wash.
The issue is a sort of catch-22. In order to reduce energy costs, manufacturers try to make their machines more efficient. These machines use hotter water and are designed to create more friction (摩擦) between the clothing in the machine. However, both of these things lead to the release of more micro-plastics. So, using Patagonia clothes as test cases, Samsung came up with a two-fold solution: One is a technology called Eco-bubbles, which creates more bubbles to make the detergent (洗涤剂) more powerful, and the other is a water purifier that can filter (过滤) out more micro-plastics.
The cooperation between the two companies is proof of how complicated protecting the environment can be. On the one hand, clothing that is well-constructed and durable is a weapon in the fight against fast fashion. On the other hand, the material used to make those clothes and the way they are washed can also add pollutants to the environment.The same goes for washing machines. There is no one-size-fits-all solution. The fight against climate change requires creative thinking and learning how to attack a problem from many angles. This will certainly lead to even more strange and fruitful cooperation between the environmentally conscious companies.

4 . David Willard has been checking the grounds of Chicago’s lakefront exhibition center for dead birds for 40 years. One morning this year he found something horrible; Hundreds of dead songbirds, so thick they looked like a carpet. Nearly 1,000 songbirds died during the night after crashing into the center’s windows. According to bird experts, the result was caused by a combination of migration conditions, rain, and the exhibition hall's low lights and walls with windows.
Birds don’t see clear glass and don’t understand it’s a deadly barrier. When they see plants or bushes through windows, they head for them, killing themselves in the process. Birds that migrate at night, like sparrows, rely on the stars to navigate. Bright lights from buildings both attract and confuse them, leading to window strikes or birds flying around the lights until they die from tiredness—a phenomenon known as deadly light attraction.
But even in the best of circumstances, spring and fall are dangerous times for migrating birds. When they migrate over major cities, the risks increase. Hundreds or thousands of dead birds may appear on city streets after a wave of migrants has passed through. In all, about 100 million to 1 billion birds die each year in North America from crashing buildings.
The good news is that people can greatly reduce the danger with some simple methods. Window strikes are easily preventable, said Anna Pidgeon, an expert at the University of Wisconsin-Madison. Architects can design windows with markings in the glass that birds can easily recognize, she said. People can paint their windows as well.

6 . Have you ever wondered what happens to your mobile phones and laptops after you throw them out to make way for a newer model? According to its latest Global E-Waste Monitor, India is the third top producer of e-waste in the world. E-waste in Indian landfill goes on to pollute soil and groundwater, affecting food supply systems and water sources.
Thankfully, the country has a new group of artists who are changing these thrown mechanical items-from mobile phones to old televisions- into large murals (壁画) and artworks to creatively show their concern for the waste problem.
Over the past quarter of a century, Mumbai’s Haribaabu Naatesan has transformed hundreds of tonnes of e-waste into art, integrating elements from nature and industry. “I get my waste material from friends, relatives and neighbours who know my interest in e-art and send me bags of thrown electronic appliances,” says Naatesan. Over his career, he has created huge murals for several companies. He has also showed his work at the India Art Fair, as well as several other national displays.
Another artist Vishwanath Davangere has also long worked with e-waste. He likes to take apart old laptops and reassemble (重新组装) them into birds, animals and plants. After retirement, he started pursuing this hobby more seriously and started selling his creations across the world. His most outstanding works include a robotic Egyptian statue with glowing red eyes and a Milky Way made from keyboard keys. He hopes to enable others to reconsider their own consumption habits and make more environmentally conscious choices.
“By giving e-waste a second chance, I aim to raise awareness about the environmental impact of electronic waste.” says Davangare, who today has a collection of more than 600 eco-art objects.

8 . My name is Ben. I am 13, and I live in Chantilly, VA. Just yesterday, June 24, I was at home watching my sister, who is mentally handicapped (弱智的). My father was at work while my mother and younger sister were at my mother’s office.
I had noticed the clouds growing darker and the ones to the east were turning green. At first I thought nothing of it, but then on TV, the weather reporter was announcing a big thunderstorm warning, one that usually brings hail (冰雹) and heavy rain.
After seeing that, I called my mother and told her about it. She told me I should not be worried because it was just a thunderstorm so we hung up. Then I looked outside and noticed it was almost pitch black at 4：30. I took a flashlight (手电筒) because I was sure the power was going to go out any second. Then no sooner had I gotten back from getting the flashlight than the weather reporter announced a Tornado Warning! I had never been in an actual tornado before, but I had seen some funnel clouds before in Montana.
Suddenly I realised I had no time to lose and I had to try to get my sister down the stairs to the basement in a matter of minutes. I surprisingly got her down there with no trouble at all and I raced back up the stairs to get the cordless phone. When I got back downstairs my dad called and told me to get downstairs immediately. I told him I was already down there! He said OK and we talked for a few seconds and then we hung up. Then_through the basement windows, the only thing_I_could_see_was_lightning.
I do not recall hearing of any deaths, or too many injuries so I guess everyone got a good head start to run to their basements. Either that or we are all lucky.
