【推荐1】Lens fogging (镜片起雾) has been troubling glasses wearers for as long as glasses have existed; it happens more often to those needing to wear masks (口罩). Researchers from ETH Zurich in Switzerland may have finally come up with a lasting solution to the problem that works whether someone is wearing a mask, or they’ve just come inside from the cold.

There’s no real mystery as to the foggy lenses. It happens when moisture (水分) in wet air, or from someone’s breath, hits a glasses lens that’s colder than said moisture, which then becomes obvious drops. It happens a lot in the winter, when people are coming in from the outside to warm places, or when people breathe out with masks, the warm, wet air goes upwards.

It’s also a problem that plagues car windows, making it hard for a driver to see. The simple solution here is to heat the windows. But adding electric heaters to glasses, which are designed to be lightweight and comfortable to wear, isn’t really a choice. So ETH Zurich researchers came up with another way to heat glasses lenses. They rely on a new type of glass coating that effectively does the same thing.

The coating is made from very thin gold in such small amounts that the added cost would be very small. The gold takes in a kind of light from the sun, causing glasses lenses to heat up to eight degrees. By doing this, it can prevent moisture in the air from forming on the glasses. The coating also cannot be seen by human eyes, not influencing people’s views. Because it’s so thin, the coating can even be applied to surfaces that are not flat.

But this method isn’t perfect. As the gold draws the energy it needs to heat lenses from the sun, the coating won’t do much good in the winter months, when it starts to get dark by late afternoon. But the researchers believe that even a small amount of electricity, like from a battery hidden away in the arms of a pair of glasses, would be enough. And with gold being one of the most valuable metals on earth and still in high demand, the researchers are looking for other metals to replace it.

【推荐2】Many got sleepless nights after Sora amazed the world with its remarkable ability of creating videos directly from text instructions. Discussions about what the artificial intelligence model can do and make a difference continue.

Some said it could give a huge blow to traditional industries such as film and television making, looking forward to the day when a movie can be created right after a novel is put into the model. But others remain skeptical about how powerful the model can be in changing the landscape of AI application.

Developed by a group of young talent from Microsoft-backed company OpenAI, the text-to-video model can generate videos up to a minute long while maintaining visual quality.

Shen Yang, a professor at the School of Journalism and Communication, Tsinghua University, said, “Sora represents a revolutionary leap in the field of AI-generated content (AIGC).”

As one of the leading scholars in AI research in China, Shen leads a team that studies the philosophy of AI. Until he learned about Sora, Shen was quite satisfied with his team’s AI-generated videos. A two-minute video on the Spring Festival produced by Shen’s team have recently won many likes on social media platforms. “Compared with the new model Sora, what we used are tools of the previous generation. There’s a huge gap in between,” said Shen.

As a frequent user of AI, Shen said the technology not only helps improve his productivity, but also benefits his daily life. His wife was suffering from cancer, and he used AI to assist in finding treatment, which has remarkably prolonged her life. He even wrote an award-winning science fiction novel using A.

However, new technologies do not mean good news to everyone. Many also concern about AI models’ safety issues since related regulations are lagging behind.

Sora is going to bring changes in many fields, including short video, film and television, news, games, advertising, education, and even industrial manufacturing, according to Shen. There is still much room to improve AI models. For instance, current AI models are not capable of drawing characters accurately and quickly. Shop signs lack meaning in Sora’s demo video showing a woman walking down a street in Tokyo. But these problems are believed to be solved as models update.

Jack Andraka created a biosensor for cancer that he says is 168 times faster, 26, 667 times less expensive and 400 times more sensitive than technology nowadays.

He’s the youngest person to have spoken in front of the Royal Society of Medicine.

Taylor Wilson was the youngest person to achieve nuclear fusion (核聚变). He was inspired by The Radioactive Boy Scout, a novel in which a kid tries and fails to build a nuclear reactor.

Taylor thought he could do better. Long story short, he wanted to build a small nuclear reactor. And he did it at the age of fourteen. He received a Thiel Fellowship, which gave him $100,000 to work on his own research.

Sara Volz performed experiments in which she grew algaebased on their oil output for the purpose of growing them as biofuel (生物燃料). This research is especially important as the world continues to search for a way to lessen our dependence on non-renewable energy. She won the top prize of   $100,000 in the Intel Science Talent Search.

Plastic usually takes thousands of years to decompose (降解), but this high school student Daniel Burd managed to do it in three months.

In an experiment, he mixed plastic bags and a special kind of dirt together, and found that they did decompose faster. He then performed tests to find the bacteria responsible for decomposing the plastics.

His solution only produces water and small amounts of carbon dioxide. He says it could easily be used elsewhere.

【推荐1】With 830 students aged between 12 and 8, Lochaber High School, at Fort William, is one of the largest secondary schools in the Highlands, It covers a huge area and many of the students come from small communities (社区 ) and travel up to 40 km to get into school each day, In the past, the school covered a much larger area and many students had to stay in one of the school dormitories, or-if older to live with local families, but other high schools have opened in the West Highlands， so the catchment area（责任区域） for Lochaber High， though still very large, is not as large as it used to be. Students travel into school by car, by bus, or by special minibus each day, and some come on foot or by bike. Most students live in Fort William itself, or in one of the surrounding villages.

At the end of their high school life, and after getting higher or advanced higher grade exam results, most students decide to move on to some form of further education. Some students can remain, taking specialised courses at the West Highland college, but most leave home in Lochaber and go south or east to cities, Many young people in this area feel that there are not enough opportunities here, Going to a city certainly means new friends, a whole new lifestyle, and a more exciting night life.

Even though Fort William is, in a way, small and far away from cities, as far as I am concerned, it is a great place to live. There is a real community atmosphere(氛围)here, and many people know, or are related to, many other people. There is always something to do or see in Fort William and there is no excuse for being bored! But there is one thing that is certain for everyone, that is, Highland hospitality. It is still very real, very alive! People look forward to seeing you!

【推荐3】The ability of music to evoke (唤起) specific, often powerful feelings is no secret to anyone who has listened to Gustav Mahler’s “Symphony No.5”, Billie Holiday’s “God Bless the Child”, the Ramones’ “I Wanna Be Sedated”, Lizzo’s “Good as Hell” or any of the other countless compositions that have found their way onto Western playlists in the past few centuries.

The emotional effects of music are the point, of course. They are also the subject of a fast-growing field of research around the world in which scientists are exploring the nature of the many “subjective experiences” — such as joy, sadness, anxiety and calmness — that music evokes.

In a recent set of experiments, researchers at the University of California, Berkeley, and their colleagues sought to determine if the feelings that people experience when listening to music “show evidence of universality”. They compared and analyzed how more than 2,800 U. S. and Chinese study participants responded to 2,168 (mostly Western) samples of instrumental music. The team identified 13 distinct and very specific feelings that the Chinese and U. S. subjects shared when listening to music, despite their cultural differences.

The music used in the research, described in the paper as “the richest set of Western music samples ever studied,” included classical, pop, rock, indie, hip-hop, R&B, country, film soundtracks, and more. An additional 189 sample of traditional Chinese music was also used. In all, the researchers gathered 375,230 judgments of the samples from the study participants.

In the first experiment, subjects listened to Western music samples (each of which was just five seconds long) and reported on the specific feelings they evoked, choosing responses from a list of 28 “categories of subjective experience” provided by the researchers. Terms on the list included “victorious/heroic”, “sad/depressing”, “joyful/cheerful”, “awe-inspiring/amazing” and “dreamy”. The team then used data-driven statistical modeling to identify the 13 shared experiences. The second experiment, which included the Chinese music, involved broad evaluations of the samples by participants—such as whether the subjects liked or disliked them or found them exciting or not. A central finding of the study, the researchers write, is that specific feelings “drive the experience of music” more than the broader features.
