3 . There are some unusual wonders of our world places that most people haven’t heard about and probably don’t want to visit. But it’s good to take a step away from everything else we’ve known and see something new!

The Library of Celsus was a public library built by Tiberius Julius Acquila in ancient Ephesus, now in modern-day Türkiye. It was built on the Mount Koressos and its construction began in 114 AD and ended in 117 AD. It is one of the best-preserved ancient buildings due to its Roman-time structures, which were built using marble, a type of hard, decorative stone.

Meteora is a group of monasteries (修道院) in Greece located on top of tall rock pillars (柱子). Meteora contains 24 monasteries built on natural sandstone rock pillars between the 11th and 15th century AD. Meteora is one of Greece's most popular tourist destinations and has been a World Heritage Site since 1988.

The Tower of Hercules is a Roman lighthouse built in 14 BC on the coast of Spain. You may be wondering how a place that was built much earlier than some of the other wonders of the world can still be considered a wonder today. Well, it was, once one of lighthouses in Europe. The tower has been rebuilt several times, but it still stands today.

Toruń is one of the oldest cities in Poland and is the capital of the province of Kujawsko-Pomorskie. Toruń was founded by Teutonic Order in the mid-13th century as an important city on the trade route between Kraków and Gdańsk. The name “Toruń” comes from two German words — “tor” means gate or tower and “tun” means settlement; therefore, “Tower settlement”.

4 . In a new study, researchers found a link between outdoor education and science grades. The findings indicate outdoor education could be a promising tool to help close gender (性别) gaps in science. “The outdoors is a space where teachers can find tangible ways to make science come alive,” says lead author Kathryn Stevenson, assistant professor of parks, recreation, and tourism management at North Carolina State University.

“The natural environment is also a place that everybody has in common. In a way, it’s also a great context for employing teaching practices like hands-on, inquiry-based learning or group work. These practices can be good for all students, but they may be particularly good for reaching students who aren’t as well-served in classroom settings,” Stevenson says.

The researchers studied the impact of an outdoor science education program called Muddy Sneakers on fifth graders’ science grades and knowledge of, and attitude about, science.

Fifth graders from western North Carolina attended between 6 and 10 days of Muddy Sneakers. They had science lessons in nearby natural areas, including state parks and school grounds, Outdoor lessons followed the standard course of study for science through hands-on activities, hikes, nature exploration, and reflections.

Researchers compared the performance of 237 students who learned about science in the classroom to 403 students who participated in the outdoor program. When researchers evaluated (评估) students’ science grades by gender, they saw that girls who participated in the outdoor science program maintained their science grades on average (平均), while girls’ average grades in the traditional science classes dropped. They also saw that participation in average grades in the traditional science classes dropped. They also saw that participation in the outdoor program helped girls learn more about how science works on average, but traditional classrooms did not.

Boys in the outdoor and traditional class settings had fairly stable science grades on average and saw similar gains in knowledge of how science works. “Outdoor education seems to be one of those contexts that helps everyone learn, but it may be really, really helpful for some students in particular,” Stevenson says.

5 . Karla Torres, a recent graduate of Francisco Bravo Medical Magnet High School in Boyle Heights, designed and created an 18th-century-inspired dress with the support of her mom to enter the yearly “Stuck at Prom” scholarship contest, sponsored by a trademarked brand of duct tape (强力胶带). The Los Angeles teen was named a finalist last week with the grand prize: a $ 10,000 scholarship.

In the beginning, Karla often spent hours online looking for clothing ideas or different styles. But it wasn't until a recent visit to the J. Paul Getty Museum — the only field trip she took in high school — that she found her inspiration from the 18th-century French paintings, featuring impressive, grand dresses.

“We’ve never made a dress, much less out of duct tape,” Karla said. “We didn’t know how much duct tape we needed. We were just doing it by trial and error.” In the end, the college-bound teen and her mom spent at least 120 hours, over many days, working on the dress, and used l4 rolls of tape.

“Tape is so tough and you can’t move it easily,” Karla said. “It was really challenging to make it all come together.” But the fashion-forward teenager overcame that challenge. Of more than 200 entries to the contest, Karla’s work was selected among the top five, judged for color, quality, originality, and the use of the brand tape.

While it’s Karla’s name officially in the contest, this whole process was more of a collective effort by her family. “It means a lot to me. The $ 10,000 prize would go a long way as I plan to attend a California State University school in August. I wouldn’t want my parents to struggle trying to find a way to pay for it,” Karla said. “It would really help my parents.”

6 . Grain Rain is the sixth solar term (节气) in the twenty-four solar terms, which is from an old Chinese saying — rain produces hundreds of grains.     1    .

The Chinese name of Grain Rain was originated from a folk story. When Cang Jie, an official in the Yellow Emperor period, created a set of characters from observing the tracks of animals, countless grain came down from the sky like rainfall.     2    . Because of the legend, April 20 has been named as the annual UN Chinese Language Day since 2010 by the United Nations’ Department of Public Information. It is roughly around the Grain Rain day, which falls between April 19 and April 21.

    3    . The southern China has the custom of picking tea in the Grain Rain season. The newly-picked spring tea in the Grain Rain season is rich in nutrients (营养物) and has the functions of heat-clearing and eyesight-clearing.     4    .

Seeing peonies (牡丹) three days after Grain Rain has become a tradition in northern China. Because the flowering of the peonies happens during Grain Rain, it is also known as the “Flower of the Grain Rain”.     5    . Chinese people also link peonies with wealth and rank.

7 . With mounting evidence that nanoplastic particles (纳米塑料微粒) are in our bodies, there is growing concern over their potential health impacts. Now a new study finds a relation between nanoplastics in the brain and a higher risk for Parkinson’s disease.

Nanoplastics appear when the plastic packaging breaks down into small pieces. These particles can enter the blood and cross the blood-brain barrier, with European researchers reporting earlier this year that in animal experiments, it can take two hours or less for certain nanoplastics to reach the brain after being eaten.

In humans, it’s long been thought that environmental factors play a role in Parkinson’s disease but specific causes are still unclear. The new study from the Duke University School of Medicine details how nanoplastics cause chemical changes in the brain that can, in turn, make Parkinson’s and related types of diseases more likely.

That’s because the nanoplastics attract a protein (蛋白质) called alpha-synuclein, known to play a role in Parkinson’s and related disorders. In lab and animal studies, the plastic’s interaction with it leads to increases in the affected neurons in the brain. This interaction appears related to favorable conditions in which Parkinson’s can develop.

The study authors note that Parkinson’s disease existed long before nanoplastics appeared in the environment, but they think that this “nanoplastics pollution in the human brain” may prove a new poison.

Further, the Duke team led by Dr. Andrew West notes that Parkinson’s disease is among the fastest growing nervous diseases in the world, even as the amazing amount of plastic pollution builds across the planet. This is expected to continue for the foreseeable future.

“The technology to monitor nanoplastics is still at the earliest possible stages and not ready yet to answer all the questions we have,” West said. “But hopefully efforts in this area will increase rapidly, as we see what these particles can do in our experiments.”
