1 . In our information-driven society, shaping our worldview through the media is similar to forming an opinion about someone solely based on a picture of their foot. While the media might not deliberately deceive us, it often fails to provide a comprehensive view of reality.
Consequently, the question arises: Where, then, shall we get our information from if not from the media? Who can we trust? How about experts—people who devote their working lives to understanding their chosen slice of the world? However, even experts can fall prey to the allure of oversimplification, leading to the “single perspective instinct” that hampers(阻碍)our ability to grasp the intricacies of the world.
Simple ideas can be appealing because they offer a sense of understanding and certainty. And it is easy to take off down a slippery slope, from one attention-grabbing simple idea to a feeling that this idea beautifully explains, or is the beautiful solution for, lots of other things. The world becomes simple that way.
Yet, when we embrace a singular cause or solution for all problems, we risk oversimplifying complex issues. For instance, championing the concept of equality may lead us to view all problems through the lens of inequality and see resource distribution as the sole panacea. However, such rigidity prevents us from seeing the multidimensional nature of challenges and hinders true comprehension of reality. This “single perspective instinct” ultimately clouds our judgment and restricts our capacity to tackle complex issues effectively.
It saves a lot of time to think like this. You can have opinions and answers without having to learn about a problem from scratch and you can get on with using your brain for other tasks. But it’s not so useful if you like to understand the world. Being always in favor of or always against any particular idea makes you blind to information that doesn’t fit your perspective. This is usually a bad approach if you would like to understand reality.
Instead, constantly test your favorite ideas for weaknesses. Be humble about the extent of your expertise. Be curious about new information that doesn’t fit, and information from other fields. And rather than talking only to people who agree with you, or collecting examples that fit your ideas, consult people who contradict you, disagree with you, and put forward different ideas as a great resource for understanding the world. I have been wrong about the world so many times. Sometimes, coming up against reality is what helps me see my mistakes, but often it is talking to, and trying to understand, someone with different ideas.
If this means you don’t have time to form so many opinions, so what? Wouldn’t you rather have few opinions that are right than many that are wrong?

2 . Researcher Ruijia Hu said wildlife habitat in crowded places like south went Ohio is becoming increasingly fragmented (分散) as forests give way to new construction. Eventually, this could make trouble to an animal with specific habitat needs like Ohio’s pileated (红冠) woodpecker.
Pileated woodpeckers have the nickname carpenter birds for their never-ending natural woodworking. They peck out holes in trees for their nests every year, creating lots of valuable homes for animals like fox squirrels and owls. “They make new nests every year. They won’t reuse old ones,” Hu said. “Other animals depend on them.”
Pileated woodpeckers are private birds that are more often heard than seen. Studying them can be especially difficult. So Hu turned to citizen science for help. To identify where woodpeckers have been seen, she used eight years of sightings collected by birders and logged into the website eBird, a free online tool and app that anyone can use to record their observations and locations. She overlaid these sightings with remote sensing data and found that corridors along rivers and creeks with abundant mature trees and deadwood helped the birds adjust to their increasingly fragmented urban landscape.
“With fragmented forests, many habitats that were once suitable for wildlife are broken up,” Hu sa id. “Wildlife is unable to find habitat big enough to meet their survival needs. And even if there are suitable habitats, the distance between them can be too great. Wildlife corridors link up these habitat patches. Since wildlife can travel and migrate from one patch to another, the probability of finding food and shelter is higher.”
“There are so many species in urban areas that we don’t pay attention to, especially when they’re not considered vulnerable,” Hu said. “With development chipping away at more forest in this crowded county, the tipping point (临界点) could come quickly and unexpectedly. You can’t fix it overnight. It’s not just about planting more trees. The birds need mature forest, so it could take 30 to 50 years to replace their habitat. At least we can protect these riverside forest corridors and see that existing trees reach maturity.”

3 . Lithium (锂) is called “white gold” for good reason. The metal’s value has been growing sharply over the last several years, in a large part because it is an essential part of batteries as well as several key sustainable technologies where energy storage is of huge significance. As electric cars, wind and solar power have grown into major players in the energy industry, lithium has become key to engineering a future free of fossil (化石) fuels.
But acquiring lithium comes at an enormous cost. It often works like this: Water containing lithium is delivered to the surface from underground and mixed with fresh water. The mixture then sits in pools to get rid of water, leaving the rest of its contents behind as brightly colored “mud”. Then heat and chemical reactions are used to get lithium from that, changing it into powder which is then packaged and shipped to buyers around the world.
Any accident that releases mine contents into surrounding communities or the groundwater supply could have unimaginable long-term impacts. To be specific, indigenous (土著的) communities often bear the damage, and political leaders have typically given little weight to their concerns. In Arizona, for example, an expanding lithium mine is threatening the Hualapai Tribe’s cultural and historic sites. Recently, mining lithium and other precious metals has brought about conflict: How do you ensure the availability of materials essential to the future of renewables while protecting those communities’ rights?
Mining of the metal is expected to increase dramatically in coming years. Over time, experts say, that will reduce greenhouse gas emissions (排放) by making electric cars more affordable and, therefore, more popular. As environmentally conscious consumers buy electric cars in ever-greater numbers, it’s important to be aware of the dirty process that powers those clean air vehicles.

5 . Restricting meals to early in the day did not affect weight among overweight adults with prediabetes or diabetes(糖尿病), according to a research presented at the American Heart Association's Scientific Sessions 2020.
“We have wondered for a long time if when one eats during the day affects the way the body uses and stores energy,” said study author Nisa M. Maruthur, associate professor of medicine in Johns Hopkins University in Baltimore. “Most previous studies have not controlled the number of calories, so it wasn't clear if people who ate earlier just ate fewer calories. In this study, the only thing we changed was the time of eating in the day.”
Maruthur and colleagues followed 41 overweight adults in a 12-week study. Most participants(参与者)（90%）were African American women with prediabetes or diabetes, and average age of 59 years. Twenty-one of the adults followed a time-restricted eating pattern, limiting eating to specific hours of the day and ate 80% of their calories before 1 pm. The remaining 20 participants ate at usual times during a 12-hour window, consuming half of their daily calories after 5 pm for the entire 12 weeks. All participants consumed the same pre-prepared, healthy meals provided for the study. Weight and blood pressure were measured at the beginning of the study；then at 4 weeks, 8 weeks and 12 weeks.
The analysis found that people in both groups lost weight and had decreased blood pressure no matter when they ate. "We thought that the time-restricted group would lose more weight,” Maruthur said. “Yet that didn't happen. We did not see any difference in weight loss for those who ate most of their calories earlier versus later in the day. We did not see any effects on blood pressure either.”
The researchers are now collecting more detailed information on blood pressure recorded over 24 hours, and they will bring this information together with the results of a study on the effects of time-restricted feeding on blood sugar, insulin(胰岛素)and other hormones and making analyses on the data. "Together, these findings will help us to more fully understand the effects of time-restricted eating on cardiometabolic(心血管代谢)health," Maruthur said.

6 . A simple blood test that can tell how well a person is likely to age is on the horizon after scientists uncovered blood signature patterns which predict ill health. The breakthrough means doctors will soon be able to check the likelihood of dementia(痴呆), cardiovascular disease and a range of other conditions many years before patients show any symptoms.
Researchers at Boston University learned to recognize combinations of specific biomarkers (生物标志物), or chemicals found in the blood, of 5,000 people in a study. They then matched these with the participants’ health outcomes over a period of eight years. They found specific patterns associated with disease and disability-free aging, as well as patterns associated with the threat of several diseases.
While various techniques already exist for predicting specific conditions, such as heart disease, the new approach will, for the most part, enable doctors to paint a comprehensive picture of their patient’s overall future health. It also promises to give people the chance to change their lifestyles or begin preventative treatment to circumvent diseases considered as a risk by their blood composition.
“These signatures show differences in how people age, and they show promise in predicting healthy ageing, changes in cognitive(认知的) and physical function, survival and age-related diseases like stroke, type 2 diabetes and cancer,” the research team said. “We can now measure thousands of biomarkers from a small amount of blood with the idea of eventually being able to predict who is at risk of a wide range of diseases long before any clinical signs become apparent.”

7 . This year, people around the world are lining up to buy electric vehicles even as prices increase. Electric vehicle, EV, demand has stayed strong even as the average cost of lithiumion (锂离子) battery cells increased to an estimated $160 per kilowatt-hour in the first quarter from $105 last year. Costs rose due to supply issues, restrictions on Russian metals and investor speculation (投机).
For a smaller vehicle like the Hongguang Mini, the best-selling EV in China, the higher battery costs added almost $1,500, equal to 30 percent of the listed price. But gasoline and diesel fuel costs have also increased since the conflict between Russia and Ukraine, and experts noted that environmental concerns are also pushing more buyers to choose EVs.
Manufacturers from Tesla to SAIC-GM-Wuling, which makes the Hongguang Mini, have passed higher costs on to consumers with price increases for EVs. More may be coming. Andy Palmer, chairman of Slovak EV battery maker InoBat, said, “rising costs will have to be passed onto carmakers.” But EV shoppers have so far not slowed down. Worldwide EV sales in the first quarter jumped nearly 120 percent, said the website EV-volumes.com.
Venkat Srinivasan is director of the Center for Collaborative Energy Storage Science at the U.S. government’s Argonne National Laboratory in Chicago. He said, “more and more people would buy EVs despite the cost of the battery and the vehicle.”
This increase in battery costs could be an unusual short-term change in a situation in which improving technology and growing production have pushed costs down for almost 30 years. Industry data showed that the $105 per kilowatt hour average cost in 2021 was down nearly 99 percent from over $7,500 in 1991.
Experts say battery costs could stay high for the next year or so, but then another large drop is likely as big investments by automakers and suppliers change the balance from shortage to surplus. “It’s like a bubble (泡沫) and for that bubble to settle down, it’s going to be at least the end of 2023,” said Prabhakar Patil, a former LG Chem executive.
The industry has long been awaiting the battery cell cost of $100 per kilowatt-hour, as a signal EVs were reaching a similar cost to fossil-fuel vehicles. But with gasoline prices high and consumer preferences changing, such cost considerations may no longer matter as much, experts say.

8 . Recently, Facebook has changed its corporate name to Meta. The company said it would better include what it does, as it broadens its reach beyond social media into areas like virtual reality (VR). The CEO Mark Zuckerberg said the existing brand could not possibly represent everything that they’re doing today, let alone in the future. He also revealed the company’s plans to build a “metaverse (元宇宙)” — an online world where people can game, work and communicate in a virtual environment.
The term “metaverse” was invented by author Neal Stephenson in Snow Crash, a science fiction published in 1992. In the work, the metaverse is a sort of 3D virtual world. It’s not simply a virtual reality game but is a persistent and shared virtual world. Or rather, the metaverse is a whole universe of shared virtual spaces seemingly linked together — you could, essentially, teleport (瞬移) between them.
Metaverse combined at the very least five technologies — they are social media, online game, Augmented Reality (AR), Virtual Reality (VR) and cryptocurrency (加密货币). Those technologies will bring users to an interactive world. AR and VR are vital for Metaverse. VR serves to present the virtual world visually and then AR will provide the audio and sensors for people to be able to interact. With Metaverse, Facebook will offer not only a texting service but also a multi-perspective virtual touch that feels like a real thing.
Facebook said that it plans to create 10,000 jobs in Europe over the next five years to work on metaverse-related endeavours (活动). The company also has introduced Oculus-branded virtual-reality headsets, and it joined with Ray-Ban to develop smart sunglasses that went on sale for $299. “Over time, I hope that we are seen as a metaverse company and I want to anchor our work and our identity on what we’re building towards,” Mark Zuckerberg said. “I view this work as critical to our mission because delivering a sense of presence — like you’re right there with another person — that’s the highest goal of online social experiences,” he said.

9 . Physical education, or PE, isn’t required for all high school students. In some schools, it isn’t offered for some different reasons. But should high school students have physical education? The answer is certainly “yes”.
Today many people don’t do sports. But as is known to all. doing sports is very important for an adult. Teaching teens the importance of a healthy lifestyle and making fitness plans now can help teens put exercise in the first place as an adult.
High school isn’t that easy. Many students are under a lot of stress. Stress can be harmful to a student’s studies and life. Doing sports can help them deal with stress better, helping them live a happier life at school.
The American Heart Association says that 10 million kids and teens suffer from obesity (肥胖). Teens should get 60 minutes of physical activity per day to control their weight and to help their bones get stronger. The increase in activities that don’t get teens to move around, such as computer games, means many teens don’t get their required exercise. PE classes act as a public health measure (措施) to encourage physical activities and help teens have healthy weights.
Not doing sports increases teens’ hazard of developing many diseases. An active lifestyle offers a good way of protection from these health problems. As much as 75 percent of health-care spending goes toward treating medical conditions that can be prevented by lifestyle changes, according to the American College of Sports Medicine.
According to the President’s Council on Fitness, Sports and Nutrition (PCFSN), students who performed five hours of physical activities each week improved their academic (学业的) performance. Students from programs with no physical activity, who used the extra time for classroom study, did not perform better on tests than those who gave up some study time in support of physical education.
