With over 6.3 million queries processed every second, Google's search results hold immense influence over public knowledge and perception. Users tend to focus only on the first few links, limiting their exposure to diverse viewpoints. This dynamic raises the issue of "filter bubbles", where users may be trapped in a cycle that strengthens their existing beliefs. Critics argue that the algorithms (算法) used by Google contribute significantly to this problem, presenting a limited selection of information based on users' preferences.

Mark Williams-Cook, founder of AlsoAsked, emphasizes the technical limitations of search engines and the misunderstandings surrounding them. He references internal Google documents revealing that the company often relies on user engagement data rather than comprehending content. This practice can promote confirmation bias, leading users towards information that aligns with their views, similar to a child choosing an unhealthy diet based only on preference.

Google acknowledges the complexity of its search system and emphasizes ongoing efforts to enhance its algorithms to tackle these issues. While the company declares that it provides a range of viewpoints, the reality remains that most users do not go beyond the top search results, which limits their exposure to diverse perspectives.

Critics believe Google should better educate users about how its search engine functions, as a clearer understanding of these processes could foster critical consumption of information. As Google evolves into an "answer engine" that provides direct information, the challenge of ensuring balanced and informative content remains crucial for public knowledge.

In Vilnius, I found comfort in a website, which offered pay-what-you-choose walking tours. These tours became the highlight of my trip. I took five tours, each morning setting out to explore the city's old town, a UNESCO World Heritage Site, and sent Stephen photos each night. Our guide, Ieva, shared her deep knowledge of history and culture. I connected with travelers from various backgrounds, including a Polish professor who invited me to an art exhibit. I also traced my grandmother's footsteps in Jewish Vilnius, visiting places she might have known. These tours, full of surprises, were perfect for a solo traveler, offering connection and flexibility. On my last day, Ieva gifted me a chocolate map of Lithuania for my enthusiastic participation.

I missed Stephen but grew increasingly confident in managing daily life challenges. I navigated apartment lockboxes, shopped in local supermarkets, and cooked, activities I was once less skillful at. In Poland, I continued with pay-what-you-choose tours, adapting to larger groups. I walked over 20,000 steps daily, often revisiting places from the tours or discovering street festivals. In Lodz, I took a private tour with Milena, who helped me find my family's history, including the homes of my great aunts and their sufferings during the war.

Stephen was hospitalized just before I returned, and we spent his hospital stay looking at my trip photos and videos. His recovery was slow, but my independent travels allowed me to manage our home smoothly, benefiting us both. This journey not only reconnected me with my roots but also empowered me with a newfound confidence in my ability to travel and live on my own.

Hutongs in Beijing are narrow streets formed by lines of "siheyuan", traditional Chinese courtyard residences. Here are three(protect) hutongs in Beijing's Xicheng district.

The 1,500-meter-long Dongjiao Minxiang is the longest of the three, which is home a few high-end restaurants and luxury stores as well as some cheap eating places and common shops. But most important attractions are a number of well-preserved Western-style buildings, which(be) once some foreign officials' homes.

The 496-meter-long Yangmeizhu West Street, is the second longest among them, is originally famous for(it) 600-year-old architecture. It also attracts tourists for several(culture) figures, such as Shen Congwen, a late 20th-century Chinese author and scholar. Walking down the hutong, you will see Beijing locals(play) Chinese chess or talking about their own ideas on arts and life.

Different from the above two hutongs, Gongmenkou Ertiao is much(short), but it is where Lu Xun Museum(locate). It is also filled with history, culture and innovations.

Like many passengers who touch down in the nation's capital, Clark has a pretty high profile. His eagle father, Captain, was given as a3 to the United States in 1982 by West German. At the time, the bald eagle was endangered, and environmentalists were4 about the present. At its low point, the bald eagle population had fallen to 417 known nesting pairs.

The United States made great efforts to5 the bald eagle population and the result was6. The species was saved and the bald eagle was7 from the list of threatened species in 2007.

Captain was part of a critical conservation breeding program,8 six healthy eaglets (雏鹰). While Clark's siblings were9 into the wild, Clark has spent his whole life under human care. Clark's claw (爪) did not form10 and just didn't give him the11 that he would need. After all, the wild is not the most12 place.

Clark travels across the country to13 flight demonstrations and other educational programs at events. People react similarly when they see him at events. They're14. Clark's physical presence leaves a lasting impression and15 people to care more about conservation efforts.

In order not to look at your phone as soon as you wake up in the morning, place your phone in another room or your coat pocket. Then spend at least the first 30 minutes of your day building good habits.

Studies show that on average we use the phone 50 to 150 times a day.You could do some reading, do a crossword puzzle or even something as simple as a walk in the yard—anything helping you get rid of your phone is OK.

One of the main problems with smart phones is that you worry if you don't check your phone regularly, you may miss out on something important, such as invitations to events or work emails. When someone has something important to tell you, they may give you a call. Therefore, it is OK to stay away from your phone sometimes.

What's going on in the real world, right in front of you, is almost always more important than what is happening online. Put away your phone when you are with someone important. For example, having dinner with friends will become awkward if you always check your phone.

That is because being addicted to the phone before going to bed greatly influences your sleep. This can harm your physical and mental health in the long run. Therefore, make it a rule to stop using your phone an hour before you go to sleep.

A. Ask your friends or family for help.

B. However, it is almost never the case.

C. Your smart phone has almost every tool that you need.

D. So you should do something meaningful to avoid looking at it.

E. A good rest should be more important than your phone at night.

F. This could be exercise like a morning run or cooking a good breakfast.

G. Many relationships have suffered because of our addiction to the phone.

Both human babies and monkeys spend more time looking at things that are unexpected or novel than they do looking at things they expect or are used to seeing. We used a task that relies on this behavior — originally developed to test whether human babies can sense their own heartbeats — to see if monkeys also have this ability.

We first got our monkeys to sit in chairs in front of a computer screen and linked them to electrocardiograms (心电图) to monitor their heartbeats. Then we played videos of either a yellow or green cloud bouncing (弹跳) up and down accompanied by beeping sounds. Sometimes the bouncing and beeping were synched (同步) to match the monkey's heartbeat, while at other times they were out of sync. If the monkeys had a sense of their own heartbeats, they would find the in-sync bouncing less interesting than the out-of-sync bouncing, and therefore would spend more time looking at the out-of-sync image.

We tested four monkeys and, just like human babies, they looked at the shapes that bounced and sounded out of sync with their heartbeats for significantly longer than the in-sync shapes. Additionally, the extent to which our monkeys paid more attention to out-of-sync shapes than in-sync shapes was veryakin to the difference in human babies. These findings strongly suggest that monkeys have an inborn sense of their own heartbeats, just like human babies can do exactly.

Our work shows that monkeys and humans have a comparable sense of their own heartbeats and establishes a method for testing this ability across species. In humans, this skill is thought to be central to emotional experiences, self-awareness, memory, etc. Sensing one's own physiological states abnormally is related to disorders such as anxiety and depression. This work has a positive effect on establishing rhesus monkeys as an animal model for human psychological disorder research.

The skin device measures 1 square centimeter. The system contains 100 small sensors that attempt to recreate things like texture (质地), temperature and even pain. The researchers call the device Asynchronous Coded Electronic Skin, or ACES, which can process information faster than humans' nervous system. Machine learning methods trained the device to recognize 20 to 30 different textures. It can even correctly read Braille letters most of the time, the researchers say.

The system does not require the users' movement to work. Humans need to slide to feel texture. But in this case the skin, with just a single touch, is able to detect textures of different roughness.

A demonstration showed that the device could identify the difference between a soft ball and a solid plastic one. "When you lose your sense of touch, you essentially become numb and prosthetic users face that problem," said Benjamin Tee, leader of the research team. "So by recreating an artificial version of the skin, for their prosthetic devices, they can hold a hand and feel the warmth and feel that it is soft."

Tee said his idea for the device came from the movie Star Wars, when character Luke Skywalker loses his right hand and it is replaced with a robotic one. In the film, the new hand is able to experience touch sensations just like the real one.

The artificial skin technology is still going through experiments and development. But Tee said there had already been a lot of interest in the system, especially from the medical community. Tee said similar inventions that his team has developed include see-through skin that can repair itself when torn and a material for wearable electronic devices that gives off light.

Vihlen once made an 84-day crossing of the Atlantic Ocean in 1968. It was then the smallest boat to have made the journey. The sailing boat April Fool was 5 feet and 11 inches long. But Tom McNally broke the world record in 1993 by crossing the Atlantic in a boat that was 5 feet and 4.5 inches long.

In order to regain the world record, Hugo set out alone later that same year to cross the Atlantic from Newfoundland to Falmouth. This time he was in Father's Day, his home-built boat, which was half an inch shorter than McNally's.

During his crossing, Hugo had to sleep on his back with his knees bent. He woke every hour to check his heading direction and general sailing conditions. After facing everything the Atlantic Ocean could throw at him, and some close encounters with large ships, Hugo finally arrived in Falmouth 105 days later. He could hardly walk and had lost 34 pounds in weight, but he had regained his record.

His reception on arrival in Falmouth was hardly a hero's welcome. One of the waiting journalists found him a pizza to eat while his boat was taken to a local sailing boat club. When they arrived at the sailing club for a celebration tea, they found the club dosed. He felt a pity for that. But luckily, a member of the public brought a bottle of champagne to toast his success.

I'd always been told to take care of my older brother, Brian, who was born weak and small. I'd often tie his shoes or prepare another glass of water for him. My mom saw my larger size and strong body as a sign that I was to be a kind of guardian angel (守护天使) for Brian. However, that was not the case.

One day our school sponsored a pumpkin-carving contest. First prize was S100, and I knew just how I would spend it. There was a brand-new game I was dying to own. So I decided the first place bonus definitely had to land in my pocket.

When I had to carve the perfect pumpkin I'd picked out, it dawned on me that with my big clumsy fingers I'd surely screw it up (搞砸). I thought of Brian's smaller, delicate hands and knew he was the man for the job. I immediately begged Brian. Unexpectedly, he asked for a cut. That was fifty-fifty. Quickly doing the math in my head, I figured out even if I split (分摊) the first prize, I'd still have enough cash for the game. So I gave in to Brian's demands. With skillful hands Brian carved the perfect face, and now we had the best pumpkin ever.

Then the unexpected happened: We came in second. Unfortunately, second prize was only $50, and I needed every penny of that to buy the game. The day of the awards ceremony, the principal handed over the money to me because Brian was home, sick with cold.

If he really wanted to win, he would have been here today, I thought to myself, justifying stealing the cash from under poor Brian's runny nose. With hardly a thought, I ran to the store and bought my dream game. That night when Brian asked if we had won, I denied, afraid to look into his eyes.

The whole thing was never mentioned again until the day when Brian was packing for college. I played my usual role in helping him pack when I came across an old album filled with photos he had taken as the school photographer.

At the National Alpine Skiing Center of China, ski instructor Xin Dawei is welcoming the busiest snow season in his 9-year career. "My schedule (pack) with classes each day. The number of instructors here has grown by about a third this year to meet the fast-rising demand, hiring is still going on," he told China Economic Net (CEN) reporter.

In 2024. on JD. com. go-to e-commerce platform for Chinese device buyers, sales of ski-related equipment (record) impressive growth, with sales of ski goggles (护目镜), snowshoes and snowboards all (rise) by more than 80% year-on-year.

Out of the top ten most rapidly growing ski related equipment markets in China over the past year, eight are southern cities. In these warm regions, enthusiasts turn indoors to experience (familiar) snow fields they rarely saw before, or even make part of their post-work fitness routine.

China has become the world's largest indoor ski market, home to over half of world's total and six out of the ten biggest ones (global). Daniel, Founder of iCeMonster, a startup high-tech snow goggles seller, said that he is shifting his focus international market to China. "We're a late (come), but business is going on well," he said.

I've never been fond of cold water. If the2 isn't to my liking, I'm not going to3 myself from the pool's edge like a missile (导弹). I'm the type of person who4 their time easing into the water, lowering myself step-by-step, and5 my body to get used to the icy depths.

My complicated relationship with water is6 my dad, who I don't think has ever looked7 he dived. I wasn't raised on the river like he was. Shortly after I was born, we8 to central Florida, far away from the rapids of my father's youth.

When we finally made it to the La Mina Falls, I was worn out. My dad was already knee-deep in the water and9 fast, while I was resting on a rock.

Despite the name, a no-spend challenge doesn't mean you sit on your hands and spend no money whatsoever. After all, you don't want to fall behind on your bills, and there are some necessities you simply can't do without. The basic premise (前提) of a no-spend challenge is to cut out non-essential spending for a certain amount of time. It could be for a week, a month or even an entire year.

What can you spend money on during a no-spend challenge?

If you need to purchase something during your no-spend challenge, it should be something that's necessary and you absolutely can't do without. So groceries, yes. Candy bar in the checkout line, no. Also, no new iPhone, even if you've been dreaming about an upgrade. No new shoes, even if they're on a huge sale. This is not the time to make excuses to buy stuff you don't really need.    The goal of this challenge isn't to make life harder on yourself by cutting out spending on essential expenses.

The financial benefits of a no-spend challenge

You can use the extra money you normally would have spent to build up your emergency fund. Or you might want to put the money toward other financial goals, like saving for a new car or an upcoming vacation. While no-spend challenges are designed to be temporary, you can always extend your challenge.

A. Decide acceptable purchases.

B. What is a no-spend challenge?

C. There should be no quick-fix approach.

D. When will you start your no-spend challenge?

E. Why not treat it as more of a lifestyle change?

F. Sometimes the best way is to go on a spending freeze.

G. A no-spend challenge can be a boost to your financial situation.

"The host nation likely won't want a human inspector poking their nose around," said Lepowsky. "But even a robot has memory and sensors acquiring data." The goal is to have high-confidence inspections without the robot saving information. For example, the robot would not save radiation measurements or create floor plans of sensitive areas.

The new prototype (样机) is built on an iRobot Create 3 platform, an educational robot. Robots offer advantages over human inspectors:they can tolerate higher radiation levels, are more consistent, and can be cheaper. They also can be programmed to generate trust, such as not using cameras to avoid seeing unwanted details. The idea for the robot started with Lepowsky's adviser, Glaser, who was curious about creating a "forgetful robot" that could perform highly accurate nuclear arms inspections but forget everything afterward. This led to an even more interesting idea: "Rather than forgetting, we're not even remembering in the first place," Lepowsky said. He believes this feature can reassure hosts concerned about privacy.

Lepowsky likes the interdisciplinary nature of his work — drawing on both his robotics and policy expertise — and he likes that it requires a breadth of knowledge, not just depth. He values that his research is grounded in real-life applications for global security and nuclear nonproliferation (防扩散).

Predicting when the robot might be used in the field is difficult. "It's easy to say, today, it's not very realistic, but you have to be ready for if and when it becomes possible," said Lepowsky. Research into this problem is very active. Because arms control is changing, the specific objectives of future agreements are hard to predict. "But we can hope they will be positive, and we need to be ready, technically. "

Over 500 million people visit American public lands each year, creating many chances to harm wild places. "When you look at the numbers, it's incredible," says Watts, head of the Leave No Trace Center in Colorado, an organization aimed at minimizing human impact on nature.

Food waste takes a long time to break down, especially in certain areas. "It takes much longer for an apple core to rot in a desert than in a forest," says Blye, a teacher at the University of Utah. Leaving waste introduces animals to an unnatural diet and changes their behavior with sometimes disastrous results. Bears who taste garbage and become a threat to humans may have to be put down. "Bears can get used to unnatural food in three weeks," says Watts. "Everyone loses in this case."

Biological waste is also problematic. Dog waste brings new bacteria into the ecosystem and scares away deer. Meanwhile, human waste and toilet paper introduces dangerous bacteria into water sources.

In national parks, trails (小路) are designed to avoid sensitive areas. Stepping off the trail, even for a quick photo, can scare wildlife away. Impacts from many visitors result in long-term damage to nature and wildlife.

But people don't think of that when they see the perfect photo opportunity. "It's just such a hard thing to resist," says Blye. The risk to sensitive ecosystems isn't obvious. "It's easy to think, oh, there's wildflowers over there. I shouldn't step on that," says Blye, but these tiny ecosystems full of microscopic organisms essential to desert life provide many benefits, including reducing the risk of erosion (侵蚀) and helping absorb rainfall, and can take hundreds of years to return to its original state.

Stanford SupplyHer, a student group supporting women's health through art, hosted an event in partnership with United to Beat Malaria (UBM) to encourage funding for malaria prevention, treatment and research initiatives while tabling at White Plaza last Monday. "Knowing that malaria is especially dangerous to pregnant individuals and children makes advocacy for malaria funding and research essential for our mission," said Bista.

"We in the U. S. need to be aware of the impact of global warming on malaria because less developed countries in other parts of the world are more heavily affected by our emissions," Bista said. Last year, the U. S. experienced its first local outbreaks of malaria since 2003. Infectious disease experts have warned that climate change will spread malaria and other diseases carried by mosquitoes to areas that were once free of malaria.

This summer, after discovering the work of UBM, a global grassroots campaign of the UN Foundation, Bista met with her congressional (国会的) representatives to advocate for malaria treatment and research. To support continued funding for global malaria programs, Bista wrote to officials in Congress. "It's easy for people to feel like they are powerless with issues as big as malaria. But any person can give input to their decision makers on issues as big as these," wrote Macgan Cross, a senior advocate at UBM. "By sending messages to your elected officials in support of global health funding, you are making sure your voice is heard."

Bista encouraged students to become involved in initiatives on campus to spread awareness of malaria and other global health issues. "Global health is important to me because there are so many health inequities (不平等) around the world and health itself is important to live a fulfilling life," Bista said. "Because there are so many health inequities around the world, I want to raise awareness and help people live fulfilling lives."
