The ninth grader at the Gwinnett School of Mathematics, Science, and Technology in Snellville has received the title "America's Top Young Scientist", according to a press release from the 3M Company.

Now in its 17th year, the challenge supports middle school students to think creatively and apply STEM principles to discover real-world solutions. When the finalists were chosen, they were paired with a 3M scientist who guided them over the summer to help transform their ideas from just concepts into models. Sirish spent four months competing against nine other finalists and secured his win at the final challenge events at 3M's global headquarters in St. Paul, Minnesota.

Sirish's journey to winning the award came from watching his mother wash vegetables and fruits every day and caution him to always do so. He wondered whether washing actually made a difference.

Since 70 percent of produce in the US has pesticide residues that are linked to illnesses like cancer and Alzheimer's, it's very important to know if the fruits and vegetables are safe to eat. That's what PestiSCAND is designed to do. The device works by shining light on the surface of the produce and measuring the wavelengths that bounce back.

Sirish aims at making this technology widely accessible so that consumers will be able to make safe food choices. But he still believes people should wash their produce anyway. He plans to use the $25,000 prize from the competition to help fund his educational goal of attending MIT.

The happiest city in the world was announced.

Now is a good time to put Denmark's second-largest city, Aarhus, on your list. Located on the east coast of the Jutland Peninsula, Aarhus was recently named the world's happiest city according to the London-based Institute for Quality of Life's 2024 Happy City Index. Having four Michelin-starred restaurants, an energetic street food scene, easy access to beautiful nature escapes, and outstanding museums and galleries, Aarhus may not be as well-known as Copenhagen, but it achieved the highest score out of 1,650 cities worldwide, particularly excelling in governance and the environment.

Paris came second on the list of Romantic Cities.

A recent list by Funjet Vacations and Talker Research revealed that 34 percent of respondents ranked Maui as the most romantic destination, excelling Paris by just 1 point. Following Maui and Paris, Rome and Venice also ranked highly in romance stakes, while Cancun rounded out the top 5. While most respondents suggested waiting about a year for a first trip together, many would choose to travel sooner.

Then came the school's talent show. Posters everywhere read: "Find Your Voice" Funny but sad, Meher thought. Her art teacher, Miss Sofia, walked to her. "These are beautiful. Why don't you show your works at the talent show?" Miss Sofia suggested.

Meher shook her head nervously. "Me? On stage?" Meher thought. "With my stutter? impossible." But Miss Sofia smiled. "What if you didn't have to speak... just show your story?"

Miss Sofia's words kept Meher thinking long after class. That night, an idea flashed through Meher's mind. What if she told her story through animation (动画片)? Using her computer and a borrowed projector from Miss Sofia, Meher turned her sketches into a short animation — "The Girl Behind the Curtain."

As the images came to life, Meher felt something she hadn't felt in years — hope. The girl in the film stuttered, too. When people laughed, a shadowy curtain grew around her like walls. But whenever someone was kind or when she felt brave, she made openings in the curtain. Little by little, light broke through.

The day of the show arrived before Meher knew it. The night of the show, Meher stood behind the curtain. She didn't go on stage. But her animation played on the big screen. At first, there was silence. Then quiet voices. Then tears.

When the animation ended and Meher's name appeared on the screen, a great cheer went up from the crowd.

Jane Goodall, the world's most famous primatologist (灵长类动物学家), is reported to have passed away at the age of 91. She earned her fame through her groundbreaking research on wild chimpanzees in East Africa in the 1960s, which(complete) changed our understanding of both chimpanzees and(we).

Her work revealed that chimpanzees can make and use tools, which was once believed to be a uniquely human skill. She also observed them(eat) meat and engaging in complex social behaviors. These discoveries were regarded as major scientific(achievement).

While not(travel) widely for lectures, she lived mainly in her childhood home in England. Her death was confirmed by the Jane Goodall Institute,headquarters are in Washington, D. C.

Through her life's work, Goodall(highlight) the profound connection between humans the animal kingdom. She proved that one person's dedication can make significant difference. Her story will continue to inspire future generations of scientists and conservationists. We should all remember her message of hope and do our part(protect) nature.

I was so3 that I was going to buy myself flowers. I'd4 done this before. On the way home, I wondered why I had never really been5 to any flowers before.6, I'd been on this earth for over half a century.

7 in England, my immigrant family viewed flowers as8 since survival was our priority. Dad worked on the railways, and Mom, before her9, worked in a factory. Our small garden was filled with vegetables10 flowers, as Mom and Dad often said, "These will keep us alive if we can't get them from the11 ."

We also built an underground oven, where Mom and Dad would make flatbread. The smell of this flatbread12 us and anchored (使扎根) us to our lives in England. When Mother's Day came, Mom would say, "Why waste money on flowers? They'll just die. Buy shoes or coats instead." So, we kids made food for her at home. My mother13 years ago after a long illness. If she were still alive today, she'd probably14 her head at me for buying flowers.15, I still wish I'd had the chance to show her this beautiful flower and buy it for her on Mother's Day.

According to Travel + Leisure, the community group 5 Gyres Institute has developed an app called TrashBlitz that will record trash thrown away in national parks. By noting what kinds of trash are found, the goal is to encourage people to cut down on waste that pollutes the parks.

If you're walking through Yellowstone and find a place with lots of empty bottles or wrappers, you can use the TrashBlitz app to write down where the trash is and any clean-up work you do. This data can then be used to create plans for policy changes, including possible laws and activities to tell visitors to clean up and use things that can be recycled or used again.

The group's 2024 clean-up effort had 259 events at 58 sites, like Olympic National Park. The group collected information as well as reports from volunteers. Based on the data, they found the biggest problem is plastic, which makes up about 77% of all reported trash. Food wrappers are the most common type of plastic litter, but soda bottles, wet wipes, and bottle caps are also usual. Paper is the second most found trash, and metals and fabrics make up the rest.

"I found small colorful pieces of plastic in Biscayne National Park," a volunteer said. "I also saw lots of bags, cups, and takeout boxes broken into tiny pieces along the roads to Everglades National Park. The smaller plastic gets, the more easily it can enter the food chain and the harder it is to remove from nature."

TrashBlitz isn't just for parks: It works for local clean-ups in communities too. Recent reports include surveys in Los Angeles, Denver, and Austin. Their work is supported by laws: In 2022, the U. S. Department of the Interior said it would not allow people to use single-use plastics in parks.
