Hiking, a form of exercise older than exercise itself, is so hot right now. From2018 to 2021, the number of Americans hitting the trails increased from around 48 million to 59 million.

Hiking offers all the cardiovascular (心血管) benefits of walking. The uneven trails strengthen legs and muscles more effectively than walking on flat surfaces. This in turn improves balance and stability, making hiking a full-body workout.

. Spending time in nature and experiencing awe-inspiring landscapes can reduce stress and anxiety. A 2015 study found that people who walked in nature for 90 minutes were less likely to engage in depression — compared to those who walked in urban environments.

However, hiking does carry some risks. To ensure a safe and enjoyable experience, it's important to take a few simple precautions. If you're a new hiker, go with a friend or join a local group. Remember: The point is to be able to see the views and smell the flowers.

In conclusion, hiking is more than just exercise. By following basic safety guidelines, hikers can ensure they return home safe and ready for their next adventure. Whether you're a seasoned hiker or a beginner, the trails offer something for everyone.
 

A. Lace up your boots and start exploring.

B. Hiking also promotes mental well-being.

C. But its advantages go further than heart health.

D. Push yourself harder and faster through challenging trails.

E. It's a well-rounded activity that benefits both the body and mind.

F. Always inform someone of your plans and check in with them afterward.

G. This growth reflects hiking's appeal as a way to stay active and connect with nature.

The more extreme concerns around AI involve what's known as the singularity. In his 2010 paper The Singularity: A Philosophical Analysis, the philosopher David Chalmers describes the singularity as follows: "What happens when machines become more intelligent than humans? One view is that this event will be followed by an explosion to ever-greater levels of intelligence, as each generation of machines creates more intelligent machines in turn. This intelligence explosion is now known as the ‘singularity'." The main worry is that, if such a singularity event were to occur, we'd no longer have authority over what happens in society.

While influential figures across AI research express real concern about the singularity, however, American philosopher Daniel Dennett doesn't buy it. As-he puts it, "I am not worried about humanity creating a race of super-intelligent agents, but that does not mean I am not worried. I see other, less dramatic, but much more likely, scenarios in the immediate future that are cause for concern." He argues that smart technology presents us with more practical threats that have a far higher likelihood of occurring. As Dennett clarifies: "The real danger is not that machines more intelligent than we are will usurp (篡夺) our role as captains of our destinies, but that we will overestimate the comprehension of our latest thinking tools, easily ceding (让渡) authority to them far beyond their competence."

Take transport. It's not just aviation and shipping industries that depend on GPS for safe and efficient navigation: how many individuals now turn to their smartphones instead of using a road map? As Dennett summarizes: "Use it or lose it is the rule of thumb cited at this point... how concerned should we be that we are dumbing ourselves down by our growing reliance on intelligent machines?"

Aging is complex, and associated with growing risks of diseases of all kinds. Snyder and his colleagues have been investigating the biology of aging to better understand what changes occur and how, in order to better ease and treat these diseases. To this end, they have been tracking a group of 108 adults, with ages spanning from 25 to 70, who have been donating biological samples every few months over several years. They noticed that in some conditions, such as Alzheimer's and cardiovascular disease, risk doesn't rise gradually with time; it increases sharply after a certain age.

To see if they could identify related changes, the researchers decided to take a closer look at the biomarkers of aging. Each participant submitted an average of 47 samples over 626 days, with the longest-serving participant submitting 367 samples. This wealth of data resulted in more than 246 billion data points, which the researchers then processed, looking for patterns in the changes. Snyder and his colleagues noticed that around 81 percent of all the molecules they studied showed changes at two distinct stages. Changes peaked in the mid-40s, and again in the early 60s, with slight differences.

Despite their findings, the researchers note that their sample size is pretty small, and they tested limited biological samples. Future research could help dig further into this phenomenon, studying it in more detail, across a wider range of subjects, to better understand how the human body changes over time.

Aboard the Fish 1, a slight figure whose face is wrinkled from years in the sun and saltwater, looked from one to the other. Ocean scientist Douglas McCauley wanted to see whether the near real-time detection system he and his colleagues had developed, Whale Safe, could prevent crashes between whales and ships in the Santa Barbara Channel. By collecting data from several sources, Whale Safe forecasts to ships the chances of meeting a whale and then grades shipping companies on whether they actually slow down during whale migrations.

"We can literally watch all of the ships in California and across the whole ocean; we are better positioned than ever before to try to track damage before it occurs," McCauley said, "We are in trouble if we don't do something different, and I realized that if I kept sticking my head literally underwater or stayed in the lab, these problems weren't going to fix themselves."

Humans have worked in the seas for centuries. But as development has intensified and the planet has warmed, the 43-year-old McCauley has dared to brave the gray area between scientific research and advocacy to try to fix these problems — or at least make them visible.

"One of Doug's notable qualities as a scientist is that he is keen to explore outside the box," said Benjamin Halpern, a professor of marine biology and ocean conservation who has worked with McCauley for about a decade. "He is a very creative thinker, and able to think differently about the solutions to problems and what kinds of research and science can help inform those."

Anti-Atlas Mountains

Extending from the Atlantic coast to the edge of the Sahara and with a huge variety of terrain, the Anti-Atlas Mountains cater for even the most indecisive traveller. Above all, Anti-Atlas is agadir country (the word means wall). The landscape is dotted with these remarkable walls. Built from stone and clay, they were typically set on hilltops or cliffs to provide protection from attack.

The Mediterranean coast

Unlike Morocco's Atlantic coast, the country's Mediterranean coastline is a less well-known destination. Of all the beaches in this area, Plage Ihttpyen is the best. Hidden from view behind two enormous red cliffs east of Port Sidi Hsain, and accessible only by a steep rocky path, it's an incredible peaceful and picturesque spot, with crystalline waves lapping against the pebble shore and curious rock formations rising from the waves.

Agadir

Founded in the 16th century by the Portuguese, Agadir quickly became a booming trading post, growing rich on the profits of sugar and spices. In 1960, an earthquake destroyed most of the city and paved the way for its rebirth as a tourist resort. This is the place if you're seeking sun, sand and surf; the coastline around Agadir is the heartland of Morocco's surf scene and you don't have to look far to discover quieter surfing beaches.

Merzouga

Located at the edge of the Sahara's shifting sands, Merzouga has become one of the main desert centers for travellers. The drive there involves a dramatic journey over high mountains and remote river valleys, a panoraman (全景) outshone only by the view at the end of the road: the soaring dunes of Erg Chebbi stand in magnificence on the horizon. Climb to the top of the 150-metre-high dunes after the winter rains and you can gaze down on to Merzouga Lake, a watering hole frequented by a colony of flamingos (火烈鸟) and occasional camel herders.

Eight-year-old Faris had to get on a ship to go to his new school. What would it be like at his new school? He worried about this for the whole journey. He was also anxious that the other pupils might make fun of his teeth as he had two extra teeth in his upper jaw. Would anybody want to be his friend?

Faris didn't realise that many of the other boys felt just as lonely as he did. He eventually gathered the courage to start chatting with the other pupils, covering his teeth with his hand. He soon made some new friends.

His teachers believed that the best way to help students who were homesick was to cheer them up with sports and activities. Then there was music! The students had to take part in choir (合唱) practice, and that was when the music teacher noticed that Faris had an extraordinary voice. He hit every note perfectly!

When Faris was twelve, his friends told him about a new kind of music from Britain and America.

"It's called rock ‘n' roll! " whispered David. "The headmaster says it's a bad influence and we shouldn't listen to it…" Bruce showed Faris a black-and-white picture cut out of a magazine. It was of a handsome man with an impossibly cool haircut standing on his toes (脚趾) as he sang with his eyes closed. That guy's called Elvis! The government wants to ban him because he makes his fans go crazy. He's the greatest music star in the world! This sounded exciting to Faris — the shy boy liked the idea of people going crazy for him, too.

He and four of his friends slipped into the teachers'office one night. They gathered around the radio and switched it on… There was a rolling beat, a loud guitar. and a bouncing piano rhythm (旋律) that made Faris want to get up and dance. It was the most exciting thing in the world!

He and his friends listened to several rock ‘n' roll songs before slipping back to the dormitory. They were too excited to sleep.

A Deakin University study surveyed 13.217 Australian teens (ages 12-18) and (find) 73% prefer reading paper books, while only 15% read daily for fun. Nearly 30% (rare) read outside schoolwork. Popular choices include fantasy and mystery novels, but interest drops as teens grow older, with girls reading more than boys.

Parents and friends play a (big) role in book recommendations than schools. Teens explain that paper books "feel real," cause less eye strain than screens, and avoid phone distractions. However, half spend most free time on social media or watching videos, (leave) little space for reading.

Researchers link regular reading to better grades, mental health, and career success. With (globe) literacy (识字) rates declining (shown in PISA tests), they urge action: (family) should share book talks, schools should protect library time, teachers could use apps to make reading interactive. They also group teens seven reading types, from "daily bookworms" to "screen lovers," suggesting (tailor) solutions like book clubs or digital-storytelling projects.

Supported by Australian libraries and publishers, study highlights the need to balance digital life with the timeless joy of reading.

Parkes' inspiration came from her own experience with2 issues that began when she was 7. She struggled to see her friends on the playground and often3 things at home. Her parents took her to hospital, where she was prescribed (开处方)4 .

"The first time I put them on, I was5 at how clearly everything looked," Parkes said. As she grew older and became more aware of social inequality, she became worried about those who6 something as essential as clear vision. "What if people donate unused glasses so others could see clearly?" She7 the idea. Her mother was supportive and helped her make a plan of8 .

They started with a drive to collect glasses through social media and9 drop boxes in their community, receiving 75 pairs of glasses. After her story was10 on TV, the project gained more support. To ensure the donated glasses were11 matched with the right individuals, Parkes carefully observed the process and even worked with doctors to12 the glasses.

Looking ahead, Parkes envisions long-term goals for the I Wanna See Project, including13 it to other states.

"The14 she showed was really touching," Parkes' mother remarked. "Despite her tight schedule, she remains15 to improving the life of many people."

•Accept others as hey are

Keeping that in mind, remember you cannot change others. Even if you try changing others, you will only be hurting yourself in the process. The best course of action would be to change yourself. This is how you will become emotionally intelligent and happier.

•Try using "I" statements.

Hiding your emotions can harm relationships. When your feelings are hurt. it's good to voice it straightforward. The best way to do this is by using "I" statements. For example, say, "I feel heart-broken." instead of "You made me feel heart-broken." This allows you to communicate your feelings without blaming others.

•

Negative thoughts can cloud your judgment. However, in over 70% of cases, we let them take hold and this is completely wrong. Whenever the other person is behaving in an upsetting manner, ask yourself if you have done anything to make them feel like that. Self-reflection helps you respond thoughtfully rather than letting emotions take control.

•Mind your words and actions.

In emotional moments, especially during arguments, we often say or do things we later regret. When emotions run high, anger or impatience can take control of us. Instead of reacting without forethought, consider taking a moment to reflect before responding.

A. Question your actions.

B. Avoid those negative thoughts.

C. Tell others how you feel in a nonjudgmental way.

D. Just like you, everyone else is entitled to their own beliefs.

E. Express your needs clearly and encourage others to do so.

F. During this moment, calm your emotions and respond sensibly.

G. To better yourself, it's essential to develop emotional intelligence.
