Since the Warring States Period (战国时代), the ancient people loved sweets and developed methods of producing sugar. In the Tang Dynasty, there was huge progress in the technology of sugar making. And sugar, the precious product once only served to the emperors and princes, also went into common people's homes. With the cultural and economic (经济的) development of Song and Yuan Dynasties, people became less interested in only tasting sweetness. In the Ming Dynasty, some people added pictures with good luck into the bowl of sugar, and sugar painting appeared.

Sugar painting is different from normal painting. Sugar painters use syrup (糖浆) as the material, a spoon as the "paintbrush", and a smooth table as the "paper". To make syrup, they have to make sugar hot before painting. Since syrup may become hard if it cools, the painters have to produce the work very quickly. They move the spoon full of syrup up and down, left and right. Soon a sugar painting is done.

However, it's a pity that this folk art is dying recently. The sugar painting that used to be rich in shapes has become poorer and poorer because of fewer needs. What's worse, few people seem to be willing to pass on the art except those aging sugar painters.

For most people, painting is a kind of art and difficult to understand. However, sugar painting has pulled the art down into people's daily lives. Through it, we may see the spiritual support of the ancient people across centuries. Now, sugar painting has been listed as an intangible cultural heritage (非物质文化遗产) in China. Therefore, the art should be remembered, missed and passed on.

In Western cultures, bread holds a significant place. In France, the baguette is more than just a type of bread; it is a symbol of French culture. The process of making a baguette requires patience and skill, from kneading the dough to baking it to a perfect golden-brown crust. French people often enjoy baguettes with cheese, butter, or cold cuts, and it is a common sight to see them walking down the street with a freshly baked baguette under their arm. This simple yet iconic food represents the French love for good food, their appreciation for the artisanal, and their relaxed lifestyle.

Food also plays a crucial role in cultural celebrations. In the United States, Thanksgiving is a major holiday centered around a large meal. The traditional Thanksgiving dinner includes turkey, mashed potatoes, cranberry sauce, and pumpkin pie. These foods are not only delicious but also have historical and cultural significance. Turkey, for example, was one of the foods served at the first Thanksgiving feast in 1621, symbolizing the harvest and the cooperation between the Pilgrims and the Native Americans.

One Friday, I3 that the students were in low spirits after working hard on a new concept all week. I knew I need to4 my students. So I asked them to5 their classmates' names on a piece of paper, leaving a6 between each name to write down some nice things about their classmates. As they left the room, they7 me the papers. On Monday, I gave each student a list with8 words about them. Soon, the whole class were9 and became happy again. By the end of that day, Taylor walked to me and said, "Thanks!"

Several years later, word reached me that Taylor was seriously ill. I made my way to the hospital to visit him. Lying in bed, Taylor had lost the10 of speech. But to this day, I can still11 every word from his mother. "I'm afraid he has12 time. I want to show you something that he had always13." Tears in eyes, she14 unfolded the torn paper, which was exactly the one with all the good things his classmates had said about him. "Taylor15 it." Taylor's mother said.

That was when my heart was touched and torn.

You may experience better brain function. Eggs provide choline — a key substance that enhances communication between brain cells, ensuring messages are delivered efficiently like a well-organized delivery system. Thus, eating eggs regularly can strengthen your memory. What's more, the nutrients in eggs act like brain fuel, keeping you focused during classes or while doing homework.

You may have healthier eyes. Eating eggs helps protect your eyes with natural substances that act as natural sunglasses, blocking harmful light like screen blue light. Egg yolks contain more eye guarding nutrients than carrots, reducing eye fatigue (疲劳) during study sessions.

You can have stronger muscles and bones. Eggs provide quality protein for muscle repair after exercise, while their vitamin D works with other nutrients like calcium and phosphorus to strengthen bones. Regular consumption supports muscle growth during daily activities and keeps bones strong.

It may seem like other foods are much better at making you feel full, but eggs are actually an excellent selection. They are the ideal mix of protein and fat and can be extremely satisfying and filling. By consuming more eggs, you are able to significantly decrease short term food and snacks.

A. You can get more energy quickly.

B. You can feel satisfied for longer time.

C. Eggs are a good source when you're busy.

D. So regular egg consumption helps maintain clear vision.

E. They can help maintain bone structure and prevent weakness.

F. This makes it easier to remember school lessons or daily tasks.

G. When you eat eggs every day, this is what happens to your body.

The researchers started by asking 300 participants how often they tended to share good news, and how other people in their lives generally responded to their good news. Then, six times a day for 10 days, the researchers asked participants to report on how grateful they were in the moment, how recently they'd had a social encounter, whether they'd shared good news with that person, and how close they felt to the person as a result.

Afterward, the researchers analyzed the results to look for patterns. They found those who shared positive events with others felt more grateful in the moment and closer to the person with whom they shared the news. In addition, people with a tendency to share good news and receive enthusiastic responses were the most grateful in the group, overall.

Sharing good news calls attention to the good things happening in your life, says Alexandra Gray, study coauthor of Northeastern University. For example, you might tell a friend what a great time you had over the holidays, and inrecounting what happened, you can re-experience the positive feelings and become even more appreciative.

Getting an enthusiastic response to your good news is also important, says Gray, because it makes you feel recognized, and cared for in a way that strengthens your relationship, and also leads to gratitude.

Though there's still more research to be done, Gray suggests people not hold back on sharing their good news with others, or on showing enthusiasm when others share good news with them. We all have a role to play in helping positivity spread.

DNA is the world's oldest data storage device. The most amazing thing about DNA is that it can potentially be used to store any type of data. Putting information into DNA uses a process called encoding. "Your computer stores information in a binary format (二进制), zeroes and ones," notes Karishma Matange, a computational biologist. "Encoding works to change these zeroes and ones into A, C, G and T, the DNA bases that can store information." The order of the bases in DNA is called sequence (序列), which spells out the information it holds. To pull information back out from the DNA, you rewind the process.

Scientists can store DNA for long periods. But it requires freezing temperatures, special equipment and dangerous chemicals, which makes the process costly. James Banal, a scientist in San Carlos, California, and his team came up with a new method T-REX. His team uses this method to trap DNA in a material similar to plastic. "Plastics are durable." Banal points out. Besides, T-REX is a cheap alternative to enclose DNA.

To test it, the team encoded the Jurassic Park theme music and a person's genome into DNA. Then they put the DNA in the glassy plastic. Damp and heat are DNA's biggest threats. But the T-REX material keeps damp out. The researchers heated it up to 75° Celsius. Later, they got the DNA by breaking the coating down. The best part, Banal says, is that the broken-down material can be reused to store DNA again.

Banal and his colleagues want to use the T-REX method to preserve genetic data or even safely store biological samples that will be launched into space. And we might one day use it to store the massive amounts of data people generate every day.

Nancy, 56, has been practising yoga with Coupland for about a decade, and she says why she keeps coming back is the community. She's become friends with Coupland and her fellow students: they go cycling, meet up for tea, go hiking, even go on vacation together.

"Social isolation (隔离) is the new smoking, in terms of death rate." says Dr. Alexandra Papaioannou, director of the Geras. Centre for Aging Research. "Older adults tend to have fewer social ties. As seniors leave the work force, they're not getting that daily connection. Plus, family members may not live near and spouses (配偶) may have passed away." she adds.

A study published by the Journal of Aging Health found that loneliness and social isolation could lead to higher chances of depression and weakened thinking abilities, greater risks of heart diseases, memory loss, and a reduced quality of life.

Another study found that older adults who exercised with others demonstrated better physical function and memory abilities than those who didn't exercise at all or exercised alone. And compared with those who exercised alone, older adults who participated in group fitness had significantly better muscle strength, attention, memory and overall function.

For seniors, group fitness classes are a good way of getting much-needed exercise and an opportunity to socialize.
