2 . What if “looking your age” refers not to your face, but to your chest? Osaka Metropolitan University scientists have developed an advanced artificial intelligence (AI) model that uses chest radiographs (光片) to assess a person’s biological age. More importantly, when it is different from the chronological age (实足年龄), it can signal a link with chronic (慢性的) diseases. These findings mark a breakthrough in medical imaging, paving the way for improved early disease detection and intervention.
The research team, led by graduate student Yasuhito Mitsuyama and Dr. Daiju Ueda from the Department of Diagnostic and Interventional Radiology at the Graduate School of Medicine, Osaka Metropolitan University, first constructed a deep learning-based AI model to estimate age from chest radiographs of healthy individuals. They then applied the model to radiographs of patients with known diseases to analyze the relationship between AI-estimated age and each disease. Given that AI trained on a single dataset tends to over fit, the researchers collected data from multiple institutions.
For the development, training, internal and external testing of the AI model for age estimation, a total of 67,099 chest radiographs were obtained between 2008 and 2021 from 36,051 healthy individuals who underwent health check-ups at three facilities.
To confirm the usefulness of AI-estimated age using chest radiographs as a biomarker, an additional 34,197 chest radiographs were collected from 34,197 patients with known diseases from two other institutions. The results showed that the difference between AI-estimated age and the patient’s chronological age was positively correlated with a variety of chronic diseases. In other words, the higher the AI-estimated age compared to the chronological age, the more likely individuals were to have these diseases.
“Chronological age is one of the most critical factors in medicine,” stated Mr. Mitsuyama. “Our results suggest that chest radiography-based apparent age may accurately reflect health conditions beyond chronological age. We aim to further develop this research and apply it to estimate the severity of chronic diseases, to predict life expectancy and to forecast possible surgical complications.”

5 . We all know the grandmotherly wisdom of serving chicken soup to someone with a cold, but does this particular meal really have the same effect as the medicine? Could the chicken soup save people a trip to the local hospital?
You won’t find studies in humans that prove chicken soup can fight off a cold, but there’s enough evidence to make it worth trying. One study published in the medical journal Chest suggested that chicken soup might have anti-inflammatory (消炎的) effects, which could possibly cure symptoms of upper respiratory (上呼吸道) tract infections (感染). Researchers studied the movement of neutrophils-a type of white blood cell-when combined with soup. They found that the movement of neutrophils was reduced in the presence of soup, suggesting a possible anti-inflammatory effect that could at least reduce cold symptoms (症状).
“There are substances in chicken soup that could affect cells in the body, which could potentially have medicinal effects, but whether they are good or bad for you, we didn’t test,” said study author Dr. Stephen Rennard, Larson Professor of Medicine at the University of Nebraska Medical Center in Omaha. Because the study was done in a laboratory and not in humans, Rennard cautions that it remains to be seen whether one would even absorb the substances (物质) that appeared to have beneficial effects in the lab. The researchers did not actually separate specific substances in soup that might be beneficial, “nor did we show what it would do in a living person, let alone a living person with a cold,” he added.
“Chicken soup might be useful, but lots of more research is required,“ Rennard said. “There is some possibility that there is a medicinal basis to it, but ‘some,’ ‘suggests’ and ‘possible’ are the key words.”
1. Why did people believe chicken soup could help with a cold?A.They had enough scientific evidence. | B.They got the idea from old experience. |
C.They were fond of the special soup. | D.They learnt it in the medical journal. |
A.By making neutrophils much less active. | B.By speeding the movement of neutrophils. |
C.By producing a type of white blood cell. | D.By making cold symptoms worse. |
A.They could affect cells in the body. | B.They are useless for curing a cold. |
C.They can’t be absorbed by humans. | D.They can only be found in chicken soup. |
A.He never caught a bad cold. | B.He didn’t like chicken soup. |
C.He didn’t know medicinal basis. | D.He would do some more research. |
6 . Whether you feel like taking a trip, or you just need some fun, you’ll enjoy this list of popular tourist attractions.
Alabama: Alabama Gulf Coast Beaches
If Alabama wasn’t the location for your next summer beach vacation, you may want to reconsider. There are 51 kilometers of white sand beaches made almost entirely of quartz grains (石英颗粒) washed down from the Appalachian Mountains thousands of years ago. That’s probably why over six million people visit Alabama’s Gulf Coast Beaches every year. Ten dollars per person.
Alaska: Kenai Fjords Wildlife Cruise
Alaska is the place to go for spotting breathtaking (令人惊叹的) wildlife. In fact, the number of visitors who travel to Alaska to see wildlife has increased by 45 percent. The Kenai Fjords Wildlife Cruise will bring you up close to whales, sea lions and sea birds. It is a five-hour trip that starts at noon and covers 88 kilometers of sea, and it will be the best $98 you ever spent.

7 . Jeannette Frescas was not concerned about the Thomas Fire until the fire reached her neighborhood in Ventura, California. “At midnight, I woke up with a flashlight in my face,“ Frescas told CNN.“I looked out of my window and there were flames, a hundred feet, all around us.”
Like many residents, Frescas was caught off guard by the fire that had roared across Southern California for 13 days. She’s one of tens of thousands of residents who got into cars and fled as winds drove the third-largest fire in modern state history through Ventura and Santa Barbara counties.
“What was once a paradise (天堂) was like a war zone (地带),” Frescas said of her apartment, which was destroyed by the fire. “It’s the scariest thing I’ve been through in my entire life.” Ventura resident Patricia Rye woke up to her son-in-law pounding on her door. She didn’t get a chance to pack any valuables. “I didn’t have time to take anything,” Rye said. “My wallet, or any of my personal things.”
The fire was so terrible that more than 8,400 firefighters were working around the clock to save lives and contain (控制) it. Twelve thousand people were evacuated (撤离) in Santa Barbara County, with animals at the local zoo threatened as well. Santa Barbara Zoo closed and many animals were placed into cages in case of possible evacuations. The zoo had kept most animals indoors, away from smoke.
Meanwhile, residents who had evacuated their homes in Ventura County-where the fire began-were allowed to return on Saturday. Jim Holden considered himself lucky that firefighters saved his home and items. “They put a water screen between my house and the house next door that was burning in an attempt to save it,“ he said. “They broke in and they saved my family photos and my computer, and things that they thought would be important to me.”

9 . Our species’ incredible capacity to quickly acquire words from 300 by age 2 to over 1, 000 by age 4 isn’t fully understood. Some cognitive scientists and linguists have theorized that people are born with built-in expectations and logical constraints (约束) that make this possible. Now, however, machine-learning research is showing that preprogrammed assumptions aren’t necessary to swiftly pick up word meanings from minimal data.
A team of scientists has successfully trained a basic artificial intelligence model to match images to words using just 61 hours of naturalistic footage (镜头) and sound-previously collected from a child named Sam in 2013 and 2014. Although it’s a small slice of a child’s life, it was apparently enough to prompt the AI to figure out what certain words mean.
The findings suggest that language acquisition could be simpler than previously thought. Maybe children “don’t need a custom-built, high-class language-specific mechanism” to efficiently grasp word meanings, says Jessica Sullivan, an associate professor of psychology at Skidmore College. “This is a really beautiful study, ” she says, because it offers evidence that simple information from a child’s worldview is rich enough to kick-start pattern recognition and word comprehension.
The new study also demonstrates that it’s possible for machines to learn similarly to the way that humans do. Large language models are trained on enormous amounts of data that can include billions and sometimes trillions of word combinations. Humans get by on orders of magnitude less information, says the paper’s lead author Wai Keen Vong. With the right type of data, that gap between machine and human learning could narrow dramatically.
Yet additional study is necessary in certain aspects of the new research. For one, the scientists acknowledge that their findings don’t prove how children acquire words. Moreover, the study only focused on recognizing the words for physical objects.
Still, it’s a step toward a deeper understanding of our own mind, which can ultimately help us improve human education, says Eva Portelance, a computational linguistics researcher. She notes that AI research can also bring clarity to long-unanswered questions about ourselves. “We can use these models in a good way, to benefit science and society, ” Portelance adds.
