2 . Blue light blocking (BLB) glasses are supposed to protect eyes from the effects of short-wave length light from our smartphones, computer screens and LED lights. Given how much time we spend on our devices, using this type of glasses sounds like a smart investment, right?
Elizabeth Esparaz, an eye specialist based in Cleveland, Ohio, says the science that producers share as they promote these glasses can be confusing and doubtful. Blue light is not just about tech devices, and it’s not always bad. “The sun produces much more blue light than human-made devices, and it’s actually advantageous,” says Dr. Esparaz. It helps our mood and sleep-wake cycle. The problem is blue light at night: It prevents the release of melatonin, a substance helping regulate our body and making us sleepy.
So, in theory, wearing BLB glasses should help people who watch movies in bed or read from a tablet at night avoid wakefulness. A review study from the University of Oklahoma that looked at 24 previous studies found that people affected by sleep disorders, jet lag (时差反应) and shift work dropped off to sleep faster after using these glasses. “So to some extent, these glasses are useful to some people,” saysDr. Esparaz. But the effectiveness is not wide and does not extend beyond certain cases.
As for eye strain (疲劳), a condition of the eyes usually caused by a long period of looking at screens, an Australian study showed that those wearing BLB glasses did not experience less eye strain than those using clear glasses. And another review study, also by Australian researchers, found inadequate evidence that BLB glasses could prevent serious eye problems.
“These glasses aren’t going to be harmful,” says Dr. Esparaz. But, she adds, they are maybe not as good as advertised and a lack of standardization in the industry means there’s no way to know if one pair is better than another.

3 . Nature’s beauty is all around you. Wild flowers shine in bright blues, yellows, and reds. Trees, with unique shaped branches, and leaves, decorate the horizon. Under your feet, pine needles, leaves, and grass give their natural beauty on the earth’s surface. But how many of you take the time to notice all of nature’s wonders?
Hannah Bullen-Ryner is an artist who not only takes the time to “smell the roses”, but she uses them as a medium to craft stunning portraits of birds. Bullen-Ryner, a photographer by trade, began her artistic hobby shortly after her twin daughters were born. The young mother suffered from depression and anxiety. To seek a solution, she turned to nature.
Bullen-Ryner started spending time alone in the woods, foraging for materials: flowers, branches, leaves, and grass. On an impulse (冲动), she started forming a portrait of a bird with the items she had gathered. When her picture was finished, Bullen-Ryner realized that she felt calmand hopeful. The process had been healing and therapeutic (有疗效的).
Bullen-Ryner tells My Modern Met, “Finding the medium of land art has allowed my art and soul to connect to the earth. As a full-time Mama of nearly three-year-old twin girls, and someone who suffers from anxiety, my art is my quiet time, my peace.”
When Bullen-Ryner creates her artwork on the forest floor, she never uses glues or any other material to bond the foraged items. This means that a single breeze is able to carry away or scatter her portrait.
“People often ask me why I don’t make something more permanent or they say it’s such a shame that it’s temporary,” Bullen-Ryner explains. “But for me,” she continues, “it is the short-lived nature of what I do that has become therapy for my soul. I get to put down all my anxieties, my fears, and all the chaos from my brain and turn it into something beautiful to honor Mother Nature. I take some photos and then walk or cycle away, leaving it all behind and feeling calmer, more connected, and truly lighter.”

4 . The first time our fifth grader bought a salad for school lunch, she proudly told me the news as soon as she walked in the kitchen door. I didn’t share her delight.
“Honey, just so you know, salad isn’t a meal. It’s a side,” I said. “Vegetables won’t keep you full.”
“But a salad’s healthy, right?” she asked.
Of course the objective answer is yes. But my answer was more complicated. I couldn’t celebrate her otherwise healthy choice because I was worried she had begun to model my dieting and restrictive eating habits she saw as a younger child — habits that included lots of salad eating (and little else) and finally led to my anorexia (厌食症) nearly two years ago. Was this monkey see, monkey do?
Even though our daughters — who are now 10, 8 and 6 — are old enough to make their own regular food choices, what my husband and I have modeled for them will make a difference. I learned something about restrictive eating from watching my own father, who often struggled with his weight. Of course, I don’t blame him for my disorder — he never intended for his choices to be a weight-loss book for me, though sadly, they were. So knowing what I know now, it would be stupid, if not irresponsible for me to think that just because I never told our daughters to restrict or to spend hours each day exercising that they wouldn’t have understood what my “healthy” lifestyle really meant. To be clear, there are countless medical reasons why some parents chose restrictive diets, but when restriction or a diet becomes a way of life that starts to affect relationships, that’s not healthy.
I knew I was wrong to shame the salad our daughter bought for lunch, which is why I reconsidered my response and told her that salad for lunch was, indeed, a healthy choice, and that it should include cheese, meat or nuts, which would keep her brain focused for the rest of her school day. She smiled at my answer. “Well, I also have cheese, eggs and chicken on my salad.”

5 . Teachers worried about students turning in essays written by a popular artificial intelligence chatbot now have a new tool of their own.
Edward Tian, a computer science major at Princeton University, has built an App called GPTZero to detect whether a text is written by Chat GPT, which is a popular chatbot that has caused fears over its possibility for immoral uses in American academic circles. His motivation to create the computer program was to fight what he sees as an increase in AI plagiarism (剽窃). Since the release of ChatGPT in 2022, there have been reports of students using the language model to pass off AI-written assignments as their own. Many teachers have reached out to him after he released GPTZero, telling him about the positive results they’ve seen from testing it.
To determine whether an essay is written by a computer program, GPTZero uses two indicators: “confusion” and “burstiness (突发性)”. The first indicator measures the complexity of text; if GPTZero is confused by the text, then it has a high complexity and it’s more likely to be human-written. However, if the text is more familiar to GPTZero — because it’s been trained on such data — then it will have low complexity and therefore is more likely to be AI-generated. Besides, the second indicator compares the variations of sentences. Humans tend to write with greater burstiness, for example, with some longer or complex sentences alongside shorter ones. AI sentences tend to be more uniform.
In a demonstration video, Tian compared the App’s analysis of a story in The New Yorker and a Linked In post written by ChatGPT. It successfully distinguished writing between human and AI. However, GPTZero isn’t foolproof, as some users have reported when putting it to the test. He said he’s still working to improve the model’s accuracy.
Tian is not opposed to the use of AI tools like ChatGPT. GPTZero is “not meant to be a tool to stop these technologies from being used,” he said. “But with any new technologies, we need to be able to adopt it responsibly and we need to have protections.”

6 . World’s Best Spicy Foods
When it comes to the world’s best spicy dishes, we have some of the world’s hottest peppers to thank. The following spicy dishes from around the world bring the heat in the most delicious way.
Piri piri chicken, MozambiqueThe Portuguese introduced this spicy dish into Mozambique as far back as the 15th century, when they mixed African peppers with European ingredients. And it’s the red pepper that brings the spiciness to this complex, layered and delicious dish. The dish is also popular in Namibia and South Africa.
Sichuan hot pot, ChinaThe joy of this dish is not only the delightful warming ingredients of the Sichuan peppercorns, but the fact that you can cook exactly what you like in the spicy soup. Duck, seafood, chicken, pork, lamb and seasonal vegetables are all fair game for throwing into the pot to boil in a soup made with Sichuan peppercorns and dried Sichuan peppers.
Som tam, ThailandFrom northeastern Thailand, this fresh and spicy salad is a main dish at Thai restaurants around the world. Som tam turns to green papaya(木瓜) for its main ingredient. The papaya is then put with long beans or green beans and a mix of flavorful Asian essentials that include dried shrimp(虾) and fish sauce among other ingredients. Thai peppers give the salad its necessary kick.
Aguachile, MexicoThis raw marinated(腌制) shrimp dish from the western Mexico tastes as good as it looks. Tiny but powerful peppers, grown throughout Mexico, make the spicy magic happen in the aguachile, which means “pepper water” . Marinate the raw shrimp with ingredients including lime(酸橙) juice, red onion and cucumber and enjoy with fried corn pancakes.

7 . Food polluted with fungi (真菌) can be an inconvenience at best and life-threatening at worst. But new research shows that removing just one protein can leave some fungal toxins (毒素) high and dry, and that’s potentially good news for food safety.
Some fungi produce toxic chemicals called mycotoxins that not only ruin food such as grains but can also make us sick. “It is a silent enemy,” said fungal researcher Ozgur Bayram of Maynooth University in Ireland, as most people don’t notice when foods like corn or wheat are ruined.
For years, researchers have known that some fungi produce these toxins, but didn’t know all the detail. Now, Bayram and his colleagues have identified a group of proteins responsible for turning on the production of mycotoxins. Genetically engineering the fungus to remove even just one of the proteins prevents the toxins from being made, the researchers reported in the September 23 issue of Nucleic Acids Research.
“The newly identified proteins act like a keystarting a car,” Bayram said. “The researchers wanted to figure out how to remove the key and prevent the starting signal from going through, meaning that no toxins would be made in the first place.”
Bayram and his team identified the proteins in a kind of fungus named A. nidulans, revealing that four proteins come together to make the key. The researchers genetically engineered the fungus to delete each protein in turn. When any of the four proteins are missing, the key does not start mycotoxin ignition(点火装置), the team found.
Fungi and fungi-like organisms are estimated to ruin a third of the world’s food crops each year. If that contamination could be prevented, Bayram estimates the saved food would be enough to feed 800 million people in 2024.
The new research is a good start, but it will still be a challenge to try to understand how this can be operationalized for agricultural purposes. “It’s difficult to apply the technique, and getting US regulatory agencies to approve the use of a genetically modified fungus on key food crops might be difficult,” said Felicia Wu a food safety expert.

8 . It is often said that laughter is the best medicine. But some researchers at the University of Oxford think the ability to belly laughs (捧腹大笑) was unique to early humans. This, they believe, made our ancestors able to form much larger groups.
The researchers first tested the pain thresholds (临界值) of some volunteers. They divided them into two groups. One group was shown 15 minutes of comedy videos, while the other was shown boring programs.
Through this experiment, the researchers found that those who had recently experienced belly laughs were able to withstand (忍受) up to 10% more pain than they had done before watching the videos. To their surprise, the scientists also found that the other group was less able to withstand pain after watching 15 minutes of the “boring” programs.
Professor Robin Dunbar of Oxford University, who led the research, believed that belly laughs release chemicals called endorphins (内啡肽) into the body which make us feel less painful.
However, not all comedy programs had such effects, according to Prof Dunbar. For example, though clever stand-up comedy was found to be enjoyable, it had no effect on raising pain thresholds. “Things that worked very well were interesting comedies such as Mr. Bean. Situation comedies such as Friends also seemed to be particularly successful,” he added.
In order to measure endorphin levels, the researchers put a bag of ice on the volunteers’ arms to see how long they could withstand it. They found that the greater the increase in pain thresholds, the greater the amount of endorphins produced.
The purpose of Prof Dunbar’s study was not to develop a new treatment. Instead, it was to study the role of laughter in the forming of human societies two million years ago.
“The next stage will be to see whether laughing really allows people to keep together and work as a group better and be friendlier towards each other. If that is the case, then it may explain why two million years ago, the first humans were able to form large communities of up to 100,” Dunbar added.

9 . The 2023 China-Germany Automobile Conference was held in Jilin, Henan and Zhejiang recently. At the conference, people discussed plans for new energy vehicles (NEVs) and collaboration between Germany and China.
China has established a competitive edge in NEVs. In 2022, China’s market share of NEVs accounted for more than 65 percent of the global total, maintaining its position as the world’s leading NEV market for eight years, China Daily reported.
Reflecting on the journey of leading Chinese electric car manufacturer (制造商) BYD, Chairman Wang Chuanfu recalled about 2003 when BYD entered into the NEV industry amid doubts and mockery, as few people back then believed in the future of NEVs. Surprisingly, within a few years, China’s NEV exports increased greatly. In 2022, the China Association of Automobile Manufacturers reported an impressive total export volume of 679,000 NEVs.
In the European market, Chinese brands, such as BYD and Hongqi, have entered the top 50 best-selling motor companies across Europe, The Times reported. Shu Youxing, general manager of BYD International Cooperation Division and the European Automobile Sales Division, said that the company’s pure electric buses have now hit the roads of more than 100 major European cities such as Amsterdam, London and Copenhagen, helping Europeans cut carbon emissions by over 200,000 tons.
NEVs made in China are also popular in Mexico. One local, Israel Aguilar, is deeply impressed. After nearly a year of trying out a Chinese NEV, Aguilar said he may never go back to driving his traditional petrol car, stating that the NEV offers better comfort.
“Technology is truly very important in these times, especially for a vehicle. And it has been truly extraordinary for me to handle these technologies that come from China,” Aguilar told Xinhua.
The thriving global expansion of Chinese NEVs is primarily thanks to the efforts of companies to improve their capability for innovation. One major example of this is China’s drive to become the global leader in making EV batteries, fueled by an advantage in the supply chain and raw materials such as lithium (锂) and cobalt (钴).
1. What can we learn about BYD?| A．BYD exports 679, 000 NEVs each year. |

10 . John Nelson, 92, grew up in Michigan and volunteered for the army in 1945. The 18-year-old managed to get accepted, despite being colourblind. He landed on the island of Iwo Jima in the first days of the American attack to take the island from the Japanese. Nelson fought day and night for 10 days before receiving a serious wound to his right arm. The other seven men in his squadron (中队) all died. American losses included 5,900 dead and 17,400 wounded.
Nelson saw the American flag being raised on Mount Suribachi after the island was taken by the American forces. The arm would continue to trouble him the rest of his life. Suffering from anxiety and flashbacks, he was diagnosed with post-traumatic stress disorder (创伤后应激障碍).
Al Elders was a Grandville farm boy. He joined the Navy and was stationed on Guam when the bombing of Hiroshima and Nagasaki on Aug. 6 and 9,1945, basically ended the war with Japan.
War often develops lasting friendships. But for the two World War II veterans (老兵) living at Sunset Manor in Jenison, their friendship didn’t begin until about a year and a half ago. One day, Elders noticed a man sitting at a cafeteria in the Sunset Village, and that was Nelson. Seeing his Marine cap, Elders thought they would have something to talk about. And they did. The war in the Pacific is a common bond.
The two men later worked together to serve other residents at Sunset Manor. John began detailing cars during good weather and cleaning walkers in winter. Elders became his advertising manager. They donated most of their income to the Wounded Warrior project. John is less mobile now and is in care at Sunset. Elders continues to visit and to encourage his friend. A friend of Elders’ who traveled to Iwo Jima brought back a jar filled with sand from the rock y island. Elders sent the gift, along with his own wartime collections, to the Seabee Museum and Memorial Park.
