1 . Advances in artificial intelligence (AI) are indicating that accurate quake forecasting may be attainable, thereby casting doubt on the conventional wisdom that such an accomplishment is beyond our capabilities. Researchers at the University of Texas, Austin, created an AI model that, during a test run in China, correctly forecasted approximately 70 percent of earthquakes with a one-week warning and offered reliable assessments of their potential intensity.
The researchers attribute their technique’s effectiveness to its reliance on a straightforward machine leaning framework. The AI was provided with a set of statistical features based on the team’s knowledge of earthquake physics, and then instructed to train itself using a five-year database of earthquake recordings. Once trained, the AI offered predictions by detecting early indicators of quakes hidden within the planet’s low-frequency rumbles (隆隆声).
The project marks a substantial breakthrough in the exploration of AI for anticipating seismic (地震) events. According to Alexandros Savvaidis, a senior researcher heading the Texas Seismological Network, “Seismic occurrences strike without warning, often in the blink of an eye. Your readiness is all you can influence. Achieving a 70% prediction rate is a considerable achievement that could significantly restrict the impact of earthquakes, reducing both the financial burden and loss of life, and the potential to remarkably improve earthquake preparation worldwide.”
Although the effectiveness of this method in different regions remains uncertain, the researchers believe that their AI model has the potential to enhance prediction accuracy when carried out in regions equipped with dependable seismic monitoring facilities. Their next step is to test artificial intelligence in Texas, where the University of Texas’s TexNet operates a network of 300 earthquake stations and over six years’ worth of continuous records, making it an ideal location for these purposes.
Ultimately, the authors aim to combine the system with physics-based models. This approach could be particularly valuable in areas characterized by limited or inadequate data. “That may be a long way off, but many advances such as this one, taken together, are what moves science forward,” concludes Scott Tinker, the bureau’s director.

2 . Pursuing a career in travel often begins with unpaid internships where beginner guides share their passion for destinations they’ve grown to love. These roles are highly sought after by those looking to break into the industry and are particularly valued by employers who recognize the importance of practical experience and a deep understanding of the travel sector.
Essential skills & traits needed
While everyone brings their own personality to the job, there are some basic qualities that all tour guides should have:
•Energy and enthusiasm are an absolute must — when the day’s tour is done, a guide still needs to study commentary (解说) and confirm the next day’s activities, so you will often need to operate on very little sleep.
•A friendly personality is needed when interacting with clients, tour operators and the general public.
•An insight into a wide range of cultures helps a guide settle all kinds of issues, not only in the place being visited, but also among the people on the tour.
•Familiarity with emergency procedures and the capacity to remain calm during critical situations are invaluable for any tour guide. Your assurance as a tour leader can positively influence the entire group.
Be aware of the facts
Tour guiding often demands extended periods away from home, with peak work times sometimes overlapping (重叠) with cherished family holidays. Burnout is a challenge to manage, yet it doesn’t necessarily signal the end of a journey in the travel sector. The industry frequently presents opportunities in product development and sales, where your guiding experience can serve as a solid foundation for success in these new roles.

4 . Although Sir Isaac Newton did not employ his reflecting telescope to uncover novel astronomical phenomena, he did use it to completely transform how we view the world we live in and the universe as a whole.
Reflecting telescopes use mirrors to bend light and enlarge images, distinguishing them from refractors (折射望远镜) that rely on lenses. Their simplicity in construction and ability to achieve much greater sizes than refractors have led to a transformation in our astronomical knowledge and our comprehension of the universe.
As light passes through glass, various colors or bands are refracted at varying angles, leading to chromatic aberration (色差) and consequently, distorted images when viewed through a lens. In the time of Newton, the technology for producing glass and lenses was still very primitive, and the challenges associated with chromatic aberration had not been adequately addressed. Today we can make lenses that have almost no chromatic aberration but we can’t make them very large. As the size of a lens increases significantly, it becomes extremely heavy, causing its own weight to distort the lens and consequently ruin the image quality.
Newton’s telescope solved these problems. A mirror doesn’t allow light to pass. It simply bounces all the light off the surface. This means there’s no chromatic aberration. Plus, because we only need to bounce light off the surface, we can support the entire mirror on a base, reducing its weight. This allows us to build much larger mirrors without any distortion.
While Galileo is credited with the discovery of moons around Jupiter and Halley with predicting the comet’s orbit, what Newton did do was tie in mathematics, astronomy and our comprehension of the universe through the use of his telescope and his universal gravitation theory.
The original telescope constructed by Newton is preserved and maintained by the Royal Society of London. It is showcased in London and occasionally embarks on international tours as an element of exhibitions.

I’m Franklin G. Takata, better known as “Find-It Frankie” due to my exceptional tracking abilities. I will say that there’s nothing out there I can’t find. I am fortunate to have a loyal and skilled partner, Munchy, by my side. He was selected especially for me from an animal shelter by my parents on the occasion of my fifth birthday.
One Thursday afternoon, Munchy and I were playing in the garden when Mom revealed that her cherished diamond ring had disappeared, entrusting us with the task of locating it. Had I known how tricky the case would be, I might have thought twice. But I said then as I’d say today, “I assure you that there’s nothing we can’t locate”
Whenever an item disappears, my initial inquiry to Mom is, “Do you recall the last place you saw it?” “I was occupied making cookies in the kitchen,” Mom replied, “when I removed my ring and set it on the counter. However, after taking a call from your aunt, I returned to discover the ring missing!” “Hmm. Well, it couldn’t have disappeared all by itself,” I said. “Munchy, let’s go take a closer look.” Munchy led the way to the kitchen.
The counter bore no indication of the ring’s whereabouts(下落); however, the flour betrayed faint paw prints, which pointed toward the criminal’s identity. “The cat” I said. “Mr. Jingles must have been playing with the ring, causing it to drop to the ground!” Crawling on the floor, I searched high and low for the ring. My efforts were in vain.

9 . Lindsey Stallworth, a high school student from Alabama, is on her way to a promising career in paleontology (古生物学) due to an unexpected discovery on family property. For years, she had been collecting fossils on their land in Monroe County, unaware of significant scientific value. However, her teacher at the Alabama School of Math and Science, Dr. Andrew Gentry, a paleontologist himself, took an interest when she showed him her collection.
“Upon examining the fossil shark teeth Lindsey presented, I quickly identified one and became eager to learn about its origin,” said Andrew.
Lindsey guided her mentor through the rural area where she had unearthed various relics, including shark teeth. Before long, they encountered an especially significant find on the grounds: a large bone from a 34-million-year-old whale skeleton! This led the pair to launch the huge project of uncovering the rest of the bones. After two months of hard work, they’ve managed to find the animal’s skull.
“Assuming the entire skeleton is present, it may require several years for us to have the entire animal back in the lab,” Andrew explained.
Lindsey secured a research scholarship to persist in her fossil-digging expeditions alongside her instructor. Her enthusiasm for the project was at an all-time high, though she had never imagined a childhood pastime would lead her down this road. “We would go out and pick up shark teeth and fossil shells, but we never knew anyone that could tell us anything about them,” she recalled. “We just thought they were cool.”
“The Research Fellows Program allows Lindsey to gain real-world experience in scientific research and even present that research at professional conferences,” Andrew said. “ It’s a once-in-a-lifetime opportunity for a high school student to stand out when applying to college and maybe even discover a new career path.”

10 . Despite an ever-higher bar to grab the attention of students in large lecture hall, Tatiana Erukhimova, who teaches physics at Texas A&M University, has managed to get her students, as well as future generations, excited about the science.
Known as “Dr. Tatiana”, the professor performs physics tricks with boundless energy and enthusiasm in her videos. A range of everyday objects are used in her experiments, from pingpong balls and toilet paper to marshmallows, bicycle wheels and hair dryers. Videos of her dramatic demonstrations have received hundreds of millions of views across social media platforms.
However, things aren’t always easy. When she first started teaching college freshman classes two decades ago, she also struggled to grab the attention of her students. “I did not grab their attention on the first day-that was my mistake.” she says. “I missed this opportunity to bond with them from the very beginning, and then it took me a while to find my voice.”
By the second semester, she found her footing, adjusting her approach to get her students engaged. The key, she says, has been to make herself approachable and her instruction personal. And, of course, add showy demonstrations. “These demonstrations often help students to connect these abstract concepts with real life.” she says.
Physics department head Grigory Rogachev says Erukhimova’s work has helped bring visibility to the department, with about 2. 5 million subscribers on its department’s YouTube page, which has translated to a boost in research funds and physics major applicants.
As a leader in a STEM field in which women are underrepresented, she’s become a role model for some. Afiya Dhanani attended Texas A&M University after seeing Erukhimova’s videos online. “Watching Dr. Tatiana do the experiments online, especially since she was a female leader. Was more inspiring for me to even go into physics.” Dhanani said in an interview with CBS Mornings. That’s all Erakhimova says she can hope for -making physics less forbidding and more exciting.
