1 . Smiling’s A Stress Reliever
A University of Kansas study found that participants who were asked to smile during stressful tasks had lower heart rates during stress recovery. So it seems even forcing yourself to look happy helps manage tricky situations.
Beaming (笑容满面) boosts immunity. A smile releases certain hormones in the brain, including serotonin (血清素), which is associated with an improvement in immune function.
A smile can relieve your pain. Being amused also prompts the release of endorphins (内啡肽) in the brain.
Looking happy encourages positivity.
Smiling makes you welcome to others and helps you connect with them. Fortunately, with enough practice, smiling can become an automatic behavior. You can use certain situations as cues to smile. You might remind yourself to smile when you hear someone laugh or while you’re in the process of making tea. You could set a note on your phone to help remember to smile.
| A．Smiling can reduce heart rate. |
| B．Smiling may lower blood pressure. |
| C．They are the body's natural painkillers. |
| D．Study found that smiling can make one live longer. |
| E．So, if you want to stay well, you should smile more. |
| F．Smiling can boost mood, not just a response to happiness. |
| G．Thinking of a favorite person or happy memory can make you smile too. |
2 . In a video shared online, a young photographer, Lily, is seen confidently directing a well-known action movie star for a photoshopot. Even though the actor is very tall, she is not nervous. She tells him what to do like a real professional, even though she’s still quite young.
“Given his size, I asked him to make more pronounced movements,” said Lily, reflecting on the shoot in a recent interview. The young shutterbug (摄影爱好者) has already taken photos of several personalities and has earned a significant following online, with her work receiving millions of likes.
Lily’s journey into photography began when she was just four years old, with a simple point-and-shoot camera. Her father, recognizing her natural ability to connect with people, encouraged her to explore street photography. At the age of five, she captured a portrait of a renowned musician-turned-actress during a chance encounter in a store, which quickly went viral on the social media.
Since then, Lily has been receiving numerous requests to photograph top talents. “The more I photograph in public places, the more recognition I get, which in turn leads to more chances to work with well-known figures,” she explained.
Because of her young age, some have questioned how she manages to secure such high-profile shoots. Her father, who assists with minor post-production edits, explained that her unique perspective was what attracted the attention of talent agencies. “Through Lily’s lens (镜头), subjects show a different side,” he said. “Her photos capture a softer, gentler aspect of people, celebrity or not.”
Addressing concerns about the use of filters and heavy editing, Lily insists that her images are minimally processed. Her ultimate goal is to evoke (唤起) emotions through her photography and, eventually, to become a full-time portrait photographer. For now, she continues to hone (磨炼) her craft and enjoys the present moment.

3 . Southern Africa is home to most of the world’s black and white rhinos. Because of global warming, the weather in this area is changing quickly. People have worked hard to protect rhinos from being hunted, but until now, no one has really looked at how the changing weather might hurt these animals.
A research team from the University of Massachusetts Amherst has recently reported that the area will be affected by both higher temperatures and changing precipitation (降水) and the rhinos are more sensitive to rising temperatures, which will quickly increase above the animals’ acceptable maximum threshold.
Over the last 100 years, Africa’s average monthly temperatures have gone up by 0.5℃ to 2℃. Scientists think that in the next 100 years, it might get even warmer, up to 2 more degrees. This change in weather might also change how much rain we get. But here’s the thing：For animals like white and black rhinos, which people have been trying to protect for a long time, will the heat or the rain changes hurt them more? This is a big question because rhinos don’t have sweat to cool down. They stay cool by taking baths and staying in cool shady spots.
To understand how changing climate will affect rhino populations, lead author Hlelowenkhosi S. Mamba and his colleague, focused their efforts on five large national parks representing diverse landscapes in southern Africa that are home to most of the rhinos. They have found that temperature conditions in all study parks will become increasingly unsuitable for both species, but it is predicted that white rhinos will be affected earlier than black rhinos.
“This research highlights the importance of using climate predictions tor both park and rhino management,” says Randhir. “We propose that park managers now think about increasing water supplies, tree cover, watching for stress and planning to allow rhino migration as the world warms.”

4 . While there are already apps that guide blind users to a bus stop’s approximate location, those people may unknowingly end up standing too far away from the actual stop. A new app addresses that shortcoming by letting the smartphone’s camera in on the act.
Known as All_Aboard, the AI-based app was developed by a team of scientists at the Harvard-affiliated Massachusetts Eye and Ear treatment and research center. It’s made to be used along with a third-party GPS-based online navigational (导航的) map.
Users start by using other apps to get to a bus stop’s location. They then open All _Aboard and proceed to hold their smartphone up so that its back camera can “see” the surrounding street. Drawing upon a deep learning neural network which was trained on around 10,000 images of bus stops within that city, the app is reportedly able to visually identify the target stop’s sign if it’s within a range of up to 15 meters away. Once the sign has been spotted, the app guides the user via sonar-like beeps (哔哔声) which change pitch and speed as the person gets closer to the bus stop.
In field tests, 24 legally blind volunteers used both online maps and All _Aboard to locate 20 bus stops—10 in an urban setting and 10 in a suburban environment.
When it came to getting close enough to those stops, online maps alone had a success rate of just 52%, whereas All _Aboard boosted the number to 93%. Additionally, while the average distance between the map’s endpoint and the actual bus stop was 6.62 meters with online maps, it was just 1.54 meters with All _Aboard.
“Our findings suggest that the All _Aboard app could help travelers with visual impairments (视力受损) in navigation by accurately detecting the bus stop, and therefore greatly reducing their chance of missing buses due to standing too far from the bus stops,” said Massachusetts Eye and Ear’s Assoc. Prof. Gang Luo. “This study indicates that computer vision-based object recognition capabilities can be used in a complementary (补充的) way and provide added benefit to purely mapping-based, macro-navigation services in real-world settings.”
