1 . In 2016, Mark Raymond learned the hard way that life can change in a split second(一瞬间). One day, Raymond went boating with his friends. He jumped off the back of the boat and hit a sandbank, leading to a severe injury to his neck. He became paralyzed(瘫痪的)and spent months in the hospital receiving treatment. When he was allowed to leave the hospital, he realized that the hard part was just beginning. He still needed to exercise to recover his strength after finishing the outpatient(门诊病人)treatment.
However, when Raymond returned home, he realized there was a serious lack of accessible gyms or facilities that could help people with different abilities work out and improve their health in his community. The lack of them caused Raymond to take action. In 2018, he established the Split Second Foundation, a non-profit organization that provides treatment that takes up from where outpatient treatment left off.
“The Split Second Foundation has equipment for people who have different disabling conditions,” Raymond explained.“Our specially trained staff will evaluate(评估)disabled customers’ physical needs and limitations and then provide recovery, education, and ongoing fitness classes suitable for them. We’re able to push them in a recovery driven fitness environment to be their best selves.”
Raymond’s goal is to open more accessible gyms, not just in New Orleans where he lives. He hopes the Split Second Foundation can help even more people get their lives back after disastrous accidents. “People with disabilities should also be thought of as productive members of society,” said Raymond. “Anybody’s life can change in an instant due to some kind of injury or disabling condition, and we are providing what’s next.”
When Raymond couldn’t find the services he needed, he made some for himself and others. This is the sort of cleverness we love to see in the world.

3 . 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.”

4 . Urban agriculture, the practice of farming within the restrictions of a city, is becoming increasingly popular and is viewed as a sustainable alternative to big industrial farms. By some estimates, between 20% and 30% of the global urban population engages in some form of urban agriculture. But until recently, its carbon footprint remains understudied.
Using data from 73 low-tech city farms, community gardens and personal plots of land, Newell and his team compared the average carbon emissions of food produced at low-tech urban agriculture sites to those of conventionally grown crops. The team found that because of urban gardens’ relatively low yields, along with the energy used in constructing the planting beds, big-city spuds (马铃薯) were significantly more carbon-intensive than commercially grown ones. This held true even when the researchers factored in emissions from transporting commercially grown produce to often distant grocery stores. That doesn’t mean that growing vegetables in big cities is totally bad, however. “Urban farming is great, ” if imperfect, says Carola Grebitus, a food choice expert. It can be a powerful tool for job creation and education, she says, and a good way to introduce fresh produce to urban “food deserts” where healthy fruits and vegetables are hard to come by. Community gardens can also provide a place to connect with nature, and the added green space can reduce the risks of heat and flooding.
Conscious of these benefits, Newell’s team highlighted several ways to make urban agriculture more sustainable. One option is to be selective about what crops are grown. For instance, tomatoes grown in the soil of open-air urban plots had a lower carbon intensity than tomatoes grown in conventional greenhouses. Another strategy is to rely on existing constructions. Include old structures into a new garden’s design instead of taking down old buildings. Finally, take the local climate, water quality and soil into account. Growing plants that are ill-suited to an area requires more water, energy and pesticides (杀虫剂), all of which affect the environment.

5 . The more you meditate and achieve mindfulness, the better you’ll feel. There are many free meditation apps that offer guided sessions, calming playlists.
HeadspaceThis app is simple and approachable for meditation beginners. Most of the free sessions focus on teaching the users how to meditate and easing them into the practice, while also acknowledging that meditation can be difficult. Yet to get into the really good stuff, you need to pay for the full membership.
Insight TimerThe app offers a multitude of meditation bells and calming musical notes during self-guided meditations. Featuring a variety of professional instructors and courses, Insight Timer also offers more contents for free users than other apps. Although the free option is extensive, the premium version (高级版) offers courses, downloadable meditations, night mode, and daily insights.
Meditation StudioThe app groups all its free meditations together, so it’s easy to use it without paying. These meditations run from 5 to 30 minutes and are available for download, a feature that other apps typically reserve for premium members. The number of free contents, however, is limited and included mostly basics. The design of the app is also relatively plain.
Breethe: Meditation & SleepA nice feature about Breethe is the calming background music that plays while the app is open, even without opening a meditation or music. Breethe offers a lot of sleep contents, including visualizations and bedtime stories. The app does offer a few 7-day courses for free, but the majority (1,000-plus meditations) is locked behind the paywall.

6 . If sales generally feel hard to resist, the sale in front of Arron Schurevich was the ultimate test: a new car just like the one he’d loved. And it was more than a 20% discount. “I figured that I would be a fool not to take advantage of that,” says Schurevich. After he drove the car off the lot, the deal turned sour. The brand-new car quickly needed repairs. Schurevich now jokes that he paid a tax for being a fool.
Why is it so hard for the human brain to resist a discount? Spotting something you’d like to buy activates your brain’s reward circuitry (奖赏回路). It gets especially heightened if it’s something you’ve been fascinated by — say, the same car you’ve enjoyed for years. Additionally, the discount itself often registers as a win, delivering its own kind of joy, says Jorge Barraza, a consumer psychologist at the University of Southern California.
“Not only are we getting the product,” Barraza says, “but we’re also getting that reward that we discovered something; we’ve earned this extra thing.”
Stores, of course, know all this and try to push our buttons. “Limited-quantity, limited-time, scarcity-marketing promotions—they get people’s blood pumping,” says Kelly Goldsmith, who studies this as a marketing professor at Vanderbilt University.
It’s really hard to always approach sales rationally. One buying strategy experts recommend is to make a shopping list in advance and then, stick to it. Another is to research items — beforehand or on the spot, checking online — to weigh whether the sale is really a good deal.
“The human brain has essentially evolved to feel first and think next, which is why you need to give yourself time to cool off from your instant reaction when in front of a sale,” says Goldsmith.

7 . Few people realize it, but glaciers (冰川) are full of tiny air bubbles (气泡). They form as snow, accumulating over thousands of years, slowly packs into ice under its own weight — squishing the air that was trapped between snowflakes into tiny holes. Erin Pettit, a scientist, and her colleagues had suspected that bubbles could be important. To test this idea, they undertook a series of laboratory experiments.
They find that as the ice melted, the resulting fresh water rose, because it was less dense than the surrounding sea water. This created a rising current along the vertical face of the ice — a proof of what occurs at the front of a real tidewater glacier. When the glacial ice melted, the current that it produced was six times faster than what was seen with the bubble-free ice because the rising bubbles pulled the water up more quickly. The glacial ice melted 2.25 times more quickly than the bubble-free ice. “That’s a very powerful effect. If that’s the reality in nature, then it’s quite serious.”
The newly discovered bubble effect could explain some of that extra melting, says Mathieu Morlighem, a scientist. “It’s improving our understanding, but it’s not painting a darker picture of what’s happening today,” he says.
Pettit notes that in Alaska, many bays with tidewater glaciers have large populations of harbor seals. The animals shelter there while molting and raising babies. But in Glacier Bay, where the tidewater glaciers retreated (后退) many miles inland, the seal populations have declined. Pettit now suspects that the roaring rhythm of exploding bubbles provides a hiding place where seals can avoid detection by killer whale, which often find their victim by listening. The bubbles may mask the seals’ sounds — at least until the ice retreats out of hearing. This may turn out to be yet another way in which these tiny bubbles have surprisingly large-scale effects.

8 . 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.

9 . Kelli Boehle says her son Nik was an amazing and caring person. Nik was diagnosed(诊断) with cancer in 2008 when he was 17. He passed away in 2012. But Nik’s kindness and generosity have lived on long after his death.
After he was diagnosed and started treatment, Nik was granted (给予) a wish experience from the Make-A-Wish Foundation. “For just this period of time, we didn’t think about cancer, ”Kelli Boehle said. “All we thought about was enjoying our time together. ”
In 2009, Nik met another young man Nate, who was also going through cancer treatment. He’d been diagnosed a month after turning 18, and Nik learned he was too old to qualify for a wish. The night before Nik passed away, he asked his mother to help ensure that young adults fighting cancer could have their wishes come true too.
“It was like a seed he planted that just wouldn’t stop coming into my mind, ” she said. In 2012, Kelli Boehle started Nik’s Wish. The nonprofit grants wishes to young adults between the ages of 18 and 24 who are battling cancer. Nate was the organization’s first wish recipient. “It’s meant to bring them joy and know that they’re loved and that we’re fighting for them, too, ”Kelli Boehle said.
Recently, 19-year-old Jordan Morrow received her wish to attend a Taylor Swift concert as part of a trip to Los Angeles. For Morrow, who has spent the last year battling brain cancer, going to the concert has done more than lift her spirits. “I think it’s something to get me through whatever comes my way, ”she said. “And I’m thankful for Nik’s Wish for that. ”
In the 11 years since Nik passed away, the organization has granted more than 300 wishes across more than 30 states. In the beginning, Kelli Boehle says she wasn’t sure she could be a wish maker and work closely with the young adults. But now, it’s her favorite thing to do.
