Research shows that insufficient sleep disturbs hunger signals, weakens self-control and increases your risk of weight gain. Sleep inadequacy affects millions. More than one-third of U.S. adults regularly get less than seven hours of sleep per night. Nearly three-quarters of adolescents fall short of the recommended 8-10 hours sleep during the school week. First responders, including nurses, firefighters and emergency workers, are especially vulnerable due to night shifts and varying uncontrollable schedules. These patterns disturb the body's internal clock and are linked to increased appetite, poor eating habits and elevated risks for obesity and metabolic disease.

Studies show that after just one night of sleep deprivation (匮乏), reward-related areas such as the amygdala, a part of the brain that drives motivation and reward-seeking, become more reactive to inviting food. Your brain becomes more excited by junk food and less capable of resisting it. Participants in sleep deprivation studies not only rated high-calorie foods as more desirable but were also more likely to choose them, regardless of how hungry they actually felt.

Sleep is as important as diet and exercise in maintaining a healthy weight. Fortunately, even a few nights of consistent, high-quality sleep can help rebalance key systems and start to reverse some of these effects. In a culture that glorifies hustle and late nights, sleep is often treated as optional. So the next time you find yourself reaching for junk food after a short night, recognize that your biology is reacting to stress. Sleep is your most powerful tool for appetite control, energy regulation and long-term health.

Yunnan's high-altitude regions, along with its unique climate conditions, proved to be perfect for cultivating coffee. The mountains rise like a wall, blocking the moist air currents. This natural barrier gives rise to an extraordinary microclimate, which is marked by dramatic temperature differences between day and night, making it ideal for growing coffee.

Wang came to this mountainous area a few years ago for a business trip and engaged with the locals. That's how he learned about the once-splendid coffee history of the area. Afterwards, he became motivated to make a documentary in 2017, tracing China's coffee history and highlighting the unique Yunnan coffee and its reputation as "black gold" in the global market.

As he explored further, it pained him to see how the mountainside had suffered from excessive farming. In the race for profits, short-sighted farmers began tightly planting coffee plants together and increased the density from just 60 trees per tenth of a hectare to more than 330, resulting in poor quality of coffee beans. When the coffee market slumped, many locals cut down their decades-old coffee trees to make room for fruits and vegetables to survive.

Fortunately, Wang's documentary caught the attention of local authorities. Moreover, he hosted a harvest festival, where he invited all the local growers to taste the coffee they'd planted. As a result, the sale of these beans quickly became a primary source of income for many in the village. Wu Hua, a cultural new economy professor at Shanghai University said, "A coffee industry that fell into decline is now regaining its strength." Wu considered the work done by Wang as a new vision for rural revitalization.

That Saturday, after an early morning cup of coffee with Mama, Leonard, our grown brother, picked up his heavy tools and headed out for the old henhouse. Mama wanted him to tear it down for she was scared of me and Angie to play near it.

I was twelve and dogged Leonard's every step. Angie, our six-year-old sister, insisted she wanted to help, too. Mama told we would be in the way, but Leonard said, "Oh, they'll be all right." "Well, alright, but you girls watch out for rusty (生锈的) nails." Leonard worked hard to pry (撬) the stubborn, gray boards. Angie and I carried the boards to a pile he would later burn.

Suddenly, Angie started to scream and Mama came running. Sure enough, she had stepped on a rusty nail. Mama examined my sister's foot while Leonard looked at mine. On my way to see about Angie, I'd stepped on a nail, too. The grownups agreed we needed tetanus (破伤风) shots.

I hated shots. I would rather swallow a thousand pills for a thousand days than have one shot. While Leonard drove us to hospital, Mama cupped a hand around my ear. "Arlene, I need you to be brave so Angie won't be too scared. You know how she can put up a fight." Determined to be a brave girl, I didn't cry a single tear though my arm felt like it was on fire.

Then Mama lowered Angie onto the table to get the shot. That's when she made her big mistake. "Arlene, tell Angie it didn't hurt at all."

Her huge blue eyes stared into mine. I thought about how Angie trusted me the way I trusted Leonard. "If I tell her it won't hurt", I thought, "she won't ever believe me again." I knew what I had to do. I cupped my hands around my mouth and yelled, "DON'T LET THEM DO IT TO YOU, ANGIE!"

Amarri was waiting for1 at the Clearwater International Airport with her friend Hinton seeing her off when a (n)2 man caught her attention: while3 security, he had to throw away one of his liquid-containing items due to strict4 about the weight of liquid that can be allowed on planes.

The man was about to5 when throwing it away into the garbage can. That was when Amarri and Hinton decided to help: after6 the item package from the garbage can, Hinton took it home. Later, he7 opened it, only to find a personalized snow globe. On one side was the image of a pair of smiling couple with some words, "Katie, we love you. Your Grandparents."

Upon return, Amarri posted a photo of the image: online, and soon people were sharing it to8 the lost souvenir with its owner. Several employees at Things Remembered saw the9, recognized the globe as one of their products, and finally10 its owner.

11, the couple had purchased it as a souvenir to their son, Michael, to12the adoption of his 5-year-old daughter, Katie. But Michael had to13 it during his return flight after visiting his parents.

Days later, Amarri returned the souvenir14 to Michael in Tampa, and he was greatly15 by the effort of two strangers to get his lost item back.

. She asked dozens of friends and coworkers to sit at her computer answering emails while she monitored their pulse and heart rate variability. Of those participants, 80% had what Stone coined "email or screen area" — shallow or suspended breathing while working on a screen.

"," said science journalist James Nestor, the author of the bestselling book Breath: The New Science of a Lost Art, which records his investigation into the power of breath. He explained that humans have lost touch with natural breathing patterns as we spend much of the day hunched (弓身) over our screens and devices. "If you are hunched over, you can't take that soft, slow, deep breath," Nestor said.

Breathing properly has enormous positive impacts on our health and well-being. Slow breathing lowers our stress levels, increases focus, regulates our emotions and even helps us make better decisions..

Nestor suggests the simple exercise of breathing in through your nose for five to six seconds and out through your nose for five to six seconds. "As you inhale, you feel that slight expansion of that abdominal (腹部的) region, and then as you continue inhaling, try to lift that breath up to your chest area," Nestor said. "Breathe this way for two minutes a day, and that's going to make a difference." Stone found that learning an instrument helped her maintain good posture and breathing.. She also took ballroom dancing lessons, which she said had a similar effect.

A. She kept holding her breath

B. These tasks resulted in shallow chest breathing

C. She found few people around her had breathing problems

D. Stone wondered how common this was and set out to investigate

E. Poor breathing is what you see when you look at 90% of the population

F. This in turn allowed her to form better breathing habits — even while in front of a screen

G. Luckily, Nestor and Stone feel confident that it's possible to retrain our body to breathe well

Led by Sarah Meissner and Nicole Wenderoth, the research team challenged the long-held belief that the brain remains in a low-activation state during sleep. Their study, published in Nature Communications, reveals frequent changes in pupil size — from rapid shifts within seconds to gradual changes over minutes. These variations correlate with activation levels in brain regions adjusting sleep-wake cycles.

To measure pupil dynamics, scientists developed a novel method: keeping sleepers' eyes open using a medical-grade transparent glue. "We worried people couldn't sleep with open eyes, but in darkness, most forgot their eyes were open," explained lead author Manuel Carro Dominguez. The team tracked pupil changes alongside brainwave patterns, finding connections to important sleep processes like memory-boosting brain waves and deep-sleep waves.

Interestingly, pupils also responded to sounds differently depending on brain activation levels at the moment. Future studies will test whether the locus coeruleus — a tiny area in the brain that controls awakening-directly drives these pupil changes, Researchers plan to apply drugs targeting this area to observe effects on pupil dynamics. "If proven, it could explain how activation levels influence sleep quality and functions," said neuroscientist Caroline Lustenberger.

This discovery holds promise for medical applications. Pupil monitoring might help doctors find sleep problems, stress-related conditions, or early signs of memory loss by detecting abnormal brain activity. The team aims to adapt the technology for hospital use, such as tracking unconscious patients' brain activity or improving sleep disorder assessments. "The pupil acts like a window into the sleeping brain," Lustenberger noted, suggesting it could innovate upon both neuroscience and sleep medicine.

By transforming a simple eye observation into a brain activity detector, this research bridges fundamental science and practical healthcare solutions. As next-generation devices make pupil tracking more accessible, sleep labs worldwide may soon adopt this approach to unlock deeper insights into the mysteries of the sleeping mind.

Now a group of scientists have tracked down one more need for such equipment. In a paper in Royal Society Open Science, they propose that astronauts living on NASA's planned lunar base could run on the track to prevent their bodies from wasting away (变得消瘦、 衰弱) under the Moon's reduced gravitational pull.

In low-gravity environments, muscle decreases in strength, bone becomes easily broken and fitness and motor abilities decline. Even exercise, made less effective by weightlessness, struggles to counteract such effects. Alberto Minetti from the University of Milan wondered if running in a Wall of Death might provide a workout capable of limiting the body's decline. To test it he rented a 10-metre-wide Wall of Death and called in two brave volunteers.

His team tied the volunteers, a man and a woman, to ropes hanging from a crane (起重机) above the track. The ropes relieved the volunteers of five-sixths of their body weight, in effect mirroring the Moon's gravity. After some practice rounds, the volunteers could run parallel to (与……平行) the ground at speeds averaging around 20 kph, without assistance.

Dr Minetti says such motion can generate a force on the body similar to the effect of gravity on Earth. According to his calculations, running this way may be enough to battle the negative effects of lunar life. NASA may not even need to find extra room: he suggests that if the lunar shelters for the Artemis Base Camp were built in a circular design, astronauts could simply go for a jog around the inside walls. In principle it is "not a completely crazy idea," says Kevin Fong, a doctor and specialist in space medicine at University College London. But, he adds, the limited medical care available in space means he would be nervous about astronauts running at speed.

Outside of productions presented by TDM and A. R. T., the majority of the many productions staged each year are produced, directed, designed, acted and run by students with support from the Office for the Arts and a variety of student-led theater groups.

Every October, I beg my parents to take us to a pumpkin patch (园地) and every October it doesn't work out. That's why I couldn't believe my ears when my dad came home with the world's best news.

"Guess what!" he said. "I just saw a poster for the jack-o'-lantern (南瓜灯) design party in the Pumpkin Patch, and it's not too far from here."

"No way!" I said. "Can we go?"

"Pumpkin! Pumpkin! Party! Party!" chanted my little brother, Tex.

"Let's go! But I've heard a rumor that something terrible happened there." said my dad, worried.

Within minutes, Tex and I already jumped into the car and buckled up, ready to go. "I'm going to pick the gian test pumpkin," said Tex.

"Giantest isn't an actual word," I said.

"I' m going to pick the bestest pumpkin!" shouted Tex.

"I'm pretty sure bestest isn't an actual word either." I giggled. "I'm going to pick whichever pumpkin will make the scariest jack-o'-lantern."

"All right, boys! Too much excitement! What if something really goes wrong?" my dad cut in.

No response. My dad continued, "If plan A fails, we can get creative and come up with Plan B!"

Still no response.

Tex and I continued our excitement, giggling and chatting.

The drive was extra cool because we saw all kinds of Halloween decorations along the way.

"Look!" Tex said, pointing to twinkling orange lights and a flashing Pumpkin Patch sign.

"Yeah! Yes! It wasn't too far a drive," I said. "Watch out, pumpkins! Here we come!"

Coming into our sight were pumpkins of various sizes that lay in the patch.

"I pick that giant one!" Tex said, running over to pick it up. But just before he did, he said, "Ew! There's a hole in it!" Tex quickly raced to another perfectly perfect pumpkin. But when he got closer, he said, "No fair! Someone took a bite."

The Great Art of Dunhuang exhibition, held at the China Art Museum on the east bank of the Huangpu River, (be) a big hit during the National Day holiday, attracting visitors around the country. On show were some of the most (represent) and rare artifacts from the collection of Dunhuang Academy in Gansu province, which made their first public debut in the metropolis (大都会).

(feature) 168 pieces and sets of cultural relics recognized as national treasures of China, the exhibition welcomed more than 50, 000 visitors during the holiday. One of the (exhibit) was the Shengli Stele, a stone with an inscription recording the beginning of the construction of the grottoes, known as the Mogao Caves. More (impressive) six of the most typical caves had life-size reproductions on display, bringing immersive experience of the Mogao Caves to visitors. According to Zhang Yuanlin, deputy director of the Dunhuang Academy ,the six caves were carefully selected to "sketch out the concise (简明的) history of dunhuang art spanning almost a millennium".

A visitor says, We are not allowed (take) photographs while visiting the Mogao Caves. Thanks to digital technology, we can have a close-up experience with the artworks in these reproduced caves, is more than we can do by visiting the real caves."

Dunhuang, (locate) in an oasis in the Gobi Desert, once served an important trading center along the ancient Silk Road. We hope that by bringing Dunhuang artifacts to Shanghai's wider audiences, it will attract more people to visit Dunhuang in Gansu says an official with the Gansu Provincial Administration of Cultural Relics.

For those people, he is "Gloves" Greenberg. How did he get that3? He looks like any other businessman, wearing a suit and carrying a briefcase (公文箱). But he's4. His briefcase always has some gloves.

In winter, Mr. Greenberg does not act like other New Yorkers, who look at the sidewalk and5 the street. He looks around at6. He stops when he7 someone with no gloves. He gives them a pair and then he moves on, looking for more people with cold8.

On winter days, Mr. Greenberg9 gloves. During the rest of the year, he10 gloves. People who have heard about him11 him gloves, and he has many in his apartment.

Mr. Greenberg12 doing this 21 years ago. Now, many poor New Yorkers know him and13 his behavior. But people who don't know him are sometimes surprised by him. They don't realize that he just wants to make them14.

It runs in the family. Michal's father always helped the poor as he believed it made everyone happier. Michael Greenberg feels the same. A pair of gloves may be a15 thing, but it can make a big difference in winter.

Recently, it was revealed that renowned musician Tino Bao had created a digital version of his daughter, who in 2021 passed away due to a rare disease at the age of 22. With the help of Xiaoice, Microsoft Asia's AI branch based in China, Bao was able to recreate his daughter Bao Rong as an AI-powered virtual figure. Tino Bao, his family and the team went to great lengths to piece together pictures, audio-visual recordings, and narrated memories of Rong. After thousands of trials and errors, they presented the life-like digital human who speaks in both Mandarin and English. Bao has finally launched a company to bring the technological miracle to other families experiencing such loss.

However, this technological achievement has also been accompanied by many controversies. The idea of bringing back a loved one through AI may seem comforting. Still, researchers caution that constantly interacting with an AI version of a deceased loved one could potentially affect the natural grieving process, leaving individuals stuck in a state of denial. This could lead to prolonged grief and other mental health issues. Furthermore, there's a risk that people may become overly dependent on the technology, prioritizing their interactions with the AI version over forming new, real-life relationships.

With the case of Bao Rong out in the open, AI resurrection (复活) has become a business. From simple "talking pictures" that sound nothing like the loved ones to deep fake videos of actors speaking with the faces of those who passed away, the lower end of the market is more "artificial" than "intelligent". Therefore, it is crucial to establish proper regulations and ethical standards to ensure that the use of AI-resurrection technology is safe and responsible.
