1 . Zandra Cunningham is the founder of a skincare brand. She has been recognized by the media as one of the youngest and most successful business owners in America.
When she was a kid, Zandra always loved lip balms (护唇膏) and bought a lot of them. But she found they eventually hurt her lips instead of relieving the dryness because of all the chemicals in them. She then started experimenting with different ingredients (成分) together with her mom. They tried a lot of times until they found the natural and healthy combinations they liked. Slowly, Zandra began selling her products at local farmers’ markets and trade events. Before her 10th birthday, she launched her brand and hoped it would empower other young girls.
Soon, it became a challenge for Zandra to separate her personal interests from what her customers actually wanted. “There are a lot of ideas that I feel are excellent but wouldn’t fit into the market,” she said. Being part of the younger market herself, Zandra recognized the issue and improved her products after truly listening to customers. “There are so many brands doing similar things, but there’s still so much room to grow. Your customers are out there, and you just have to reach out to them. That’s what will set you apart,” the 23-year-old shared.
When asked about her experience as a promising young businesswoman, Zandra said, “It wasn’t frightening. When you’re young, fear doesn’t have a strong hold on your mindset. ‘Maybe it’s not going to work’ never really crossed my mind.”
Characterized by encouraging statements and featuring a playful color combination, the packaging (包装) is a big part of why Zandra’s business has been so impressive. “There are a lot of products on the market that seem natural, but they actually aren’t,” she said. “I make sure my packaging can help people understand what each term means, and how to read and check ingredients.”

2 . The walls of ancient Egyptian tombs (坟墓) can teach us much about the ancient Egyptians’ life. However, many paintings in the tombs were damaged by unlawful tomb diggers. Now a new study shows how a technology called portable X-ray fluorescence (pXRF) can be used to better study the paintings.
Developed in the early 20th century by physicist Henry Moseley, XRF and pXRF can be used to decide materials’ elemental composition (元素组成). Rather than the huge and immovable tool often used to study historical objects in labs, the tool needed in the pXRF study weighs only a few kilograms and can be taken into the field.
The research team headed by Philippe Martinez from Sorbonne University used the new tool to perform chemical imaging on paintings on site, allowing for the study of paint composition. As the ancient Egyptians used paints made from minerals (矿物), the paints have specific chemical markers. By using pXRF, scientists can use the chemical markers to create a map of damaged areas.
The team used the pXRF tool in the study of a painting of Ramesses II found in the tomb of Nakhtamun, which has traditionally been dated at the19th dynasty of ancient Egypt. And they discovered the necklace worn by the king in the painting may have been changed.
The king was first painted to be wearing a shebyu necklace, which was trendy during the 20th dynasty, some years after Ramesses II’s death. And it appears that the necklace was later changed to a wesekh necklace, which usually appears in paintings during his time. This means the tomb painters at first painted this 19th-dynasty ruler wearing a 20th-dynasty necklace, realized their mistake and then corrected it. The technology enabled the team to learn that the tomb owner, Nakhtamun, may actually have lived in the 20th rather than the 19th dynasty, and that the painting is not of a living king, but rather of a former ruler.
According to the researchers, the pXRF technology allows in-depth studies while helping prevent further damage. And it presents important details about the technological and artistic achievements of the ancient Egyptians.

3 . Google Flights reveals new feature to help travelers save money
Regular users of Google Flights might notice a new feature the next time they go to the site to check out airline schedules and compare flight prices.
The new feature officially announced on Monday morning in a news release is Google guidance on the cheapest time to book a flight, which adds price tracking alerts and a price guarantee option already in place.
Cheapest time to book: Google Flights said starting this week, searches that have reliable trend data will let users see in what time frame prices have typically been lowest. Users can then better decide whether to book now or later, Google said in the release.
Take flights from New York to Miami, for example, the cheapest time to book is usually from Sep 13 to Dec 7. Prices during this time are $59 cheaper on average.
Price tracking: Users who want to wait for lower fares before booking can use a price tracking feature that “can do most of the heavy lifting for you,” Google said.
Price guarantee: On some flight results, users might notice a price guarantee badge (标志) pop up (this won’t happen on every use). If you book one of these flights, Google said it will monitor the price every day before takeoff.
“If the price does go down, we’ll pay you back the difference via Google Pay. These price guarantees are part of a pilot program available for select Book on Google itineraries (行程) departing from the U. S.,” Google said in the release.

4 . The Nobel Prize in Chemistry 2023 was awarded to three American scientists Moungi G. Bawendi, Louis E. Brus and Alexei I. Ekimov “for the discovery and development of quantum (量子) dots”. They are so tiny that their size determines their properties. These smallest components of nano (纳米) technology now spread their light from televisions and LED lamps, and can also guide surgeons when they remove cancer tissue, among many other things.
Everyone who studies chemistry learns that an element’s properties are governed by how many electrons (电子) it has. However, when matter contracts to nano-dimensions quantum phenomena arise; these are governed by the size of the matter. The Nobel winners in Chemistry 2023 have succeeded in producing particles so small that their properties are determined by quantum phenomena. The particles, which are generally known as quantum dots by scientists, are now of great importance in nanotechnology.
“Quantum dots have many fascinating and unusual properties. Importantly, they have different colours depending on their size,” says Johan Åqvist, Chai r of the Nobel Committee for Chemistry.
Physicists had long known that in theory size-dependent quantum effects could arise in nanoparticles, but at that time it was almost impossible to sculpture in nanodimensions. Therefore, few people believed that this knowledge would be put to practical use.
However, in the early 1980s, Alexei Ekimov succeeded in creating size-dependent quantum effects in coloured glass. The colour came from nanoparticles of copper chloride (氯化铜) and Ekimov demonstrated that the particle size affected the colour of the glass via quantum effects. A few years later, Louis Brus was the first scientist in the world to prove size-dependent quantum effects in particles floating freely in a liquid. In 1993, Moungi Bawendi revolutionised the chemical production of quantum dots, resulting in almost perfect particles. This high quality was necessary for them to be used in applications.
Quantum dots are thus bringing the greatest benefit to humankind. Researchers believe that in the future they could contribute to flexible electronics, tiny sensors, thinner solar cells and quantum communication — so we have just started exploring the potential of these tiny particles.

5 . Exploring China is not easy even for experienced travelers, but the history instructor Jessica Gerard from Ozarks Technical Community College (OTC) knows from experience the trip is worth it. Since 2008, she’s led five groups of students across China to study its culture and history.
Gerard often reminds interested students that the trip is not a vacation—it’s an academic (学术的) course. “Anyone interested in the trip must take an online course about the history of China before they can go,” she said. “And, most importantly, students continue to learn while in China. They’re expected to listen to guides, keep a diary and write about their experiences afterward.”
OTC student Ross Weis believed his experiences in China easily transcended (超越) anything he could have learned in the classroom. In fact, it was his long-held interest in China that led him to ask about the trip after seeing a poster in the OTC library. “I’ve always been drawn to China and its rich culture and history,” Weis said. “My dad studied history in college, and I suppose that has some influence on me.”
Of all the cities and historical sites Weis visited, he said nothing could top his experience at the Great Wall. “I’d read about the Great Wall and seen it on TV, but it is so different to go there and actually experience it,” he said. “It wasn’t as worn as I had expected it to be. That was pretty cool.”
Every OTC group Gerard has taken to China has been led by her trusty tourist agent, Jim Lieu. Gerard plans her trips directly through Lieu, who keeps travel costs down for students. “Lieu and I have an excellent relationship with one another. He always knows what I want for my students, and I know what he can do,” said Gerard. “He sincerely believes that in order to build stronger communities and a better world, people around the world should get to know each other through travel.”

6 . Taking exercise in a crowded, noisy gym will improve your muscle but may not make much difference in your stress level. By contrast, hiking improves not only your physical fitness level, but your mental health as well. “I hike with friends every week. Whether I am wandering down a flat path along a river or climbing a rock y mountain in the wilderness, hiking can be beneficial to me because it exposes (使接触) me to outdoor scenes such as mountain s and rivers, which can always offer me good ideas about paintings and music,” Marry Copper, a hiker said.
Experts agree that hiking reduces stress. According to the Anxiety Disorders Association of America (ADAA), hiking increases the body’s production of endorphins, a type of chemical that improves mood (情绪). Endorphins also help you sleep more soundly, which will lower your stress level. However, not all scientists agree that hiking raises your endorphin level. Instead, some researchers believe that hiking causes the release of the chemical norepinephrine, which helps make you less excited or upset.
The controversy (争议) is ongoing, but it is clear that however it happens, hiking is useful when you are feeling anxious. Hiking can also help improve your confidence. Walking down a path is a repetitive motion, which can lead your brain into relaxing; you may “zone out” to the point where you won’t be thinking about anything in particular. Being outside in the open air may also help you exercise better because most people do indoors; getting out from under a roof can lift your spirits.
Hiking may improve your mood more than a gym workout will, but your risks are also greater. People sometimes try to make their own way rather than stick to established paths. They are proud to say they like to have an adventure. However, people who try to do something new could be attacked by wildlife and get hurt and lost. So stick to the known roads and bring a cellphone with you, and always tell someone where and when you are going hiking, even if you have a partner going with you.

7 . This is the last Christmas that Faye and Matthew have spent in their house, which has already been sold. Faye and Matthew Gooding and their five young sons appear to have perfect lives. For the couple themselves, however, this “materially perfect world” was lacking in something—so now they are giving up all their possessions to travel around the world with their children. Most of their belongings have been given to their neighbors. Faye said, “It is a relief to get rid of so many possessions. Thankfully, our parents understand and support us.”
“I hesitated for a while because some friends think Faye and I are mad to give up so much. When we told the older boys, they were so excited that they were going to have so much time as a family. It made me realize the amount of toys or material possessions can’t replace time spent with our children. They’ve had to give away so many toys, bikes and books. My wife Faye was so determined to keep to our plan,” said Matthew.
They will leave this month and plan to start their travels in Sweden where they have friends. Faye said, “My older boys plot where we go next but we hope to see Europe and over two years travel as far as Japan, America, Bali and Thailand. We don’t plan to hire any tour guides. We just depend on a compass and local people to move in the right direction.”
Faye, who posts on Instagram as a mother of five boys, added, “It is a risk because we are giving up so much. I, however, even plan to quit my job after the travel. We can’t wait to spend more time with our sons without the stresses of everyday routines. We don’t know what will happen, but we do know if we didn’t do this we would always regret it.”

9 . Which is more important for parents, making more money to give the kids a better life or spending more time with them? It is a problem for parents and it is not easy to decide. A new study shows that today’s parents are spending more time with their children than parents in the past. According to the study, today’s college-educated mothers spend about 21.2 hours a week taking care of their children. But women with less education spend about 15.9 hours. Before 1995, it was only 12 hours.
Dads are spending more time on ball games. Before 1995, fathers with college educations only spent about 4.5 hours a week playing with their children. Today, it increases to 9.6 hours a week. For fathers with high school education, the time goes up from 3.7 hours to 6.8.
These days, parents don’t care more about the cleaning or the cooking. They are trying their best to spend time with their families. As for the kids, they don’t mind how much time their parents spend with them. They just want to enjoy the time their parents do be with them.
So, take part in the kids’ activities when you are with them, such as helping with homework or playing soccer with them.

10 . Workers at the National Galleries of Scotland recently experienced quite a surprise after they X-rayed a painting by Vincent van Gogh. Hidden on the back of the painting Head of a Peasant Woman, which Van Gogh completed in 1885, was a self-portrait (自画像) of the Dutch painter. No one had ever found it.
The hidden self-portrait had been covered by glue and cardboard that had been attached to the back of the painting. “It was absolutely exciting,” Lesley Stevenson, the museum’s worker, said about the discovery. “We weren’t expecting much of the little painting when we performed the scans,” she said. But museum experts quickly changed their expectations when they looked at the X-rays. “We didn’t see much of the peasant woman, but we saw the lead white that Van Gogh used for his face showing up after the X-ray went through the cardboard,” she added.
Van Gogh painted Head of a Peasant Woman as part of a series of works focused on the working-class residents of Nuenen, a small farming community in the southern part of the Netherlands where he lived briefly in the 1880s. The woman in the painting is Gordina de Groot, a farm worker. She wears a white headpiece. In a letter that Van Gogh penned about the series in 1885 to Anton Kerssemakers, a friend, he described his excitement at his working-class subjects. “I’m working with great pleasure these days, for I would rather paint people than paint anything else,” he wrote.
Van Gogh also loved creating self-portraits, producing about 20 paintings of himself by the end of his life while he was living in Paris. Recreating his own image was a cheap way for him to practice portraiture as he didn’t have to spend money hiring models, according to a report.
Art historians at the National Galleries hope that the hidden self-portrait may help us understand the life of the artist. The museum is currently considering how to best remove the unwanted protective materials without harming the painting.
