Artificial intelligence (AI) technology may soon be a useful tool for doctors. It may help them better understand and treat diseases like liver cancer in ways that were never before possible.
Rishi Rawat, who teaches AI at the University of Southern California in Los Angeles, is part of a team of scientists researching how AI and machine learning can more easily recognize cancerous growths in the liver. Rawat provides information about cancer cells to a computer. He says, “You can put the data into them and they will learn the patterns and the pattern recognition that’s important for making decisions.”
David Agus is another researcher. He believes that machines are not going to take the place of doctors. “Computers will not treat patients, but they will help make certain decisions and look for things that the human brain can’t recognize by itself.”
Once a confirmed cancerous growth is removed, doctors still have to treat the patient to reduce the risk of cancer returning. The form of treatment depends on the kind of cancer. Nowadays, researchers take a thin piece of tissue(组织), put it on a small piece of glass and add color to see the cells better. That process could take days or even longer. Scientists say artificial intelligence can do something better than just count cells. Through machine learning, it can recognize complex patterns or structures, and learn how the cells are organized.
The hope is that machines will soon be able to make a quick identification of cancer that is free of human mistakes. Agus says the process could be done for almost no cost in the developing world and that having a large amount of information about patients is important for a machine to effectively do its job in medicine.
The researchers of the university are now only studying liver cancer. But doctors predict artificial intelligence will one day make a difference in all forms of cancer.

【推荐1】What should we do if one of our classmates suddenly falls ill or gets hurt? Here are some steps you should follow. But always remember to look for medical care after first aid (急救) if the wound is serious.
Broken bones: Take away clothing from the wound. Use an ice pack. Don’t move the hurt body part while waiting for the doctor to arrive.
Animal bites: Wash the bite area with soap and water. Pack the wound with a clean cloth if it is bleeding. If the bleeding has stopped, cover the area with a bandage and take the person to the hospital. Make sure you remember what kind of animal it is so the doctor can find the right way to treat him or her at once.
Fainting (昏厥): Have him or her lie with feet lifted a little. Don’t move the body if you think there might be wounds from the fall. Make sure he or she can breathe and let in fresh air. Clean the person’s face with a cool cloth.
Nosebleeds: Have the person sit up with his or her head tilted (倾斜) forward a little. Do not have the person tilt his or her head back because this may cause heavy breathing or coughing. Pinch (捏) the lower part of the nose for at least 10 minutes.

【推荐2】In the 1970s, chemist James Lovelock and microbiologist Lynn Margulis developed the Gaia hypothesis（盖亚假说）: all organic and inorganic components on the planet are part of one self-regulating system, working to maintain life on earth. Scientists agree that we need take significant action to control emissions（排放）. But where scientists and popular movements have thus far failed to convince the world to act, it seems that Mother Earth may have succeeded, with the never-before-seen COVID-19.
COVID-19 is estimated to have reduced carbon dioxide emission in China by a quarter. It caused factories to shut down, and slowed construction activities. Recent analysis shows a 70 percent drop in flights in February compared with January. And even getting into a car and going to a restaurant, shopping mall, or concert poses a risk of infection, which means that many people are choosing to stay at home and are consuming less, resulting in a significant reduction of their carbon footprints.
Of course, China and the rest of the world will hope to restart normal production and consumption as soon as the virus is under control. However, some positive measures have already been taken as a result of COVID-19. As the virus is thought to originate from wildlife, Chinese authorities are revising laws and regulations regarding the country's massive wildlife trade in order to prevent future epidemics（流行病）—a win for biodiversity.
The deaths of thousands of people worldwide should also serve as a lasting reminder of the fragility of life. We humans frequently ignore or repress uncomfortable thoughts of death and extinction. We would rather get on with our lives as usual, thinking everything will somehow work out in the end. Only in the face of suffering and death are we forced to view the bigger, longer-term perspective—and this is what is needed in order to react appropriately to climate change. COVID-19 has sent alarm bells ringing throughout the world.

【推荐3】Google is my doctor
When illustrator Scott Adams lost his voice, his doctors were confused.
Adams is one of an increasing number of people who have started using the Internet to get health advice. The advantages are numerous, starting of course with the obvious convenience of getting a diagnosis from the comfort of your own home.
Diagnosing minor medical problems from information on the Internet can also have an impact on society’s medical costs. You can compare insect bites with Internet pictures, ask what type they are and whether they are dangerous without wasting your busy doctor’s precious time.
However, it must be said that diagnosis is tricky, and comparing your rash(疹子) with an online photo may lead you down the wrong path.
In conclusion, the Internet is a good starting point in diagnosing your health problems, but you should always consult your doctor before acting on anything you find there.
| A．On a professional level, there is no way one doctor car be an expert in everything. |
| B．It was not until he turned to the Internet that he managed to identify his condition. |
| C．This condition was the very one that made him unable to speak |
| D．Appearance provides only ten percent of the information needed to make a diagnosis. |
| E．Do not underestimate the value of talking to real people — doctors and telephone helplines will help you put what you read into context. |
| F．To sum up, if your doctor refuses to talk to you, the Internet will give you a better solution. |
【推荐1】You might have ever noticed how some people can effortlessly talk to anyone they meet, no matter how different their backgrounds are. Or you may have seen that one person always offends someone, no matter what the topic of conversation is. These two situations describe how we can differ in our abilities to interact, get along with, and relate to others around us. In the same way that we vary in traditional academic competencies, we can vary in how socially competent we are. After years of academic research and development, this social ability is now commonly referred to as “social intelligence.”
Social intelligence is the ability to understand other people, how they work, what motivates them, and how to work cooperatively with them. It is a relationshipbased construct that centers on the way we understand others, interact with others, and present ourselves to others. As an example, you would not speak in the same way toward your 70-year-old mother as you would to your 16-yearold daughter. In our working lives, we come across different social groups including those from different countries, varying age groups and cultural identities. Being able to acknowledge and understand people’s different backgrounds is a key way to connect with them.
Our ability to navigate successfully through our lives relies heavily on our levels of social intelligence. It can affect the relationships we form with our partners and children, the friendship circles that we build, and our ability to progress in our careers and ambitions. Given the importance of social intelligence in multiple aspects of life, it is therefore in our best interest to better understand the concept of social intelligence and take the following ways to improve it.

Every summer, moist（潮湿的）air masses, known as monsoon, produce large quantities of rainfall in India, East Asia, Indonesia, Northern Australia and East Africa, which are pulled in by a high pressure area over the Indian Ocean and a low pressure area to the south.
According to Edward Cook, a weather expert at Columbia University in New York, the complex nature of the climate systems across Asia makes monsoons hard to predict. In addition, climate records for the area date to 1950, too recent and not detailed enough to be of much use. Therefore, he and a team of researchers spent more than fifteen years travelling across Asia locating trees old enough to provide long-term records. They measured the rings（年轮）or circles, inside the trunks of thousands of ancient trees at more than 300 sites.
Rainfall has a direct link to the growth and width of rings on some kinds of trees. The researchers developed a document—a Monsoon Asia Drought Atlas（地图集）. It shows the effect of monsoons over seven centuries, beginning in the 1300s.
Professor Cook says the tree-ring records show periods of wet and dry conditions. “If the monsoon basically fails or is very weak one year, the trees affected by the monsoon at that location might put on a very narrow ring. But if the monsoon is very strong, the trees affected by that monsoon might put on a wide ring for that year. So, the wide and narrow ring widths of the tree chronology（年表）that we developed in Asia provide us with a measure of monsoon variability. ” Armed with such a sweeping set of data, researchers say they now can begin to refine climate computer models for predicting the behavior of monsoons.
“There has been widespread famine and starvation and human dying in the past in large droughts. And on the other hand, if the monsoon is particularly heavy, it can cause extensive flooding,” said Eugene Wahl, a scientist who is with America’s National Oceanic and Atmospheric Administration’s paleoclimate（古气候）branch studying weather patterns over the history of the Earth. “So, to get a knowledge of what the regional moisture patterns have been, dryness and wetness over such a long period of time in great detail, I would call it a kind of victory for climate science.”

【推荐3】Brooke wanted a dollhouse and some sugar cookies. So the 6-year-old asked Alexa to get them. Alexa wasn’t her mom or babysitter. It was voice-activated home assistant powered by artificial intelligence (AI). Alexa comes with the Amazon Echo device. And it made Brooke’s wishes come true. A few days later, much to her parents surprise, a $170 dollhouse and four pounds of cookies showed up.
Alexa is not the only AI willing to order up treats for you. Apple HomePod has Siri, Google Home has its Assistant, and the upcoming Galaxy Home device will have Bixby. People who own these devices use them mainly for listening to music, checking the weather, and setting timers. According to a report, voice shopping is rare. People who do it mainly order simple things like paper towels. But many experts predict a boom in voice shopping in the near future.
But voice shopping has its downsides. Unwanted dollhouses aren’t the biggest problem. It’s usually very easy to cancel an order or return items. The thing that creeps some people out is that these assistants are always listening. They have to be able to respond when you want them. So they listen to for “Alexa” or “OK Google” or another command. When they hear it, they start recording the conversation. Some have worried about what happens to these recordings. Should companies be allowed to use them to learn about people’s shopping habits? Should police access them to solve a crime? What if someone hacks the device?
What do you think? Are you ready to start voice shopping?

【推荐1】Immersive cultural tourism has recently gained immense popularity, riding on the wave of consumer demand for interactive and engaging experiences.
“Immersive” has become a buzzword in recent years. It involves deep absorption in an environment or activity. It takes two primary forms: one constructs real or virtual worlds, transporting individuals into new worlds; while the other employs online platforms like livestreaming, videos, and augmented reality to immerse people in specific events.
Immersive cultural tourism is reshaping travel by offering deeper, more meaningful experiences that go beyond the conventional aspects of “travel, shopping, and entertainment”. It encourages in-depth exploration and interactive leisure, as demonstrated by various attractions.
In Xi’an, the Tang Dynasty Everbright City transports visitors to the magnificence of the Tang Dynasty, and the Tang Dynasty Treasure Box interactive game has gained popularity. In Yangzhou, the China Grand Canal Museum digitally showcases the Grand Canal’s history and culture, offering a comprehensive exploration experience. In Dunhuang, the Ancient Sound of Dunhuang allows visitors to explore mural paintings in an immersive manner.
These attractions breathe new life into traditional culture and present it in a fresh light. From a content perspective, immersive cultural tourism covers various cultural themes, including historical, revolutionary, and ecological aspects. These experiences immerse tourists in the past, present, and even the world of imagination. From a technological perspective, it makes use of innovations like 5G, high-quality screens, virtual reality and artificial intelligence, enabling visitors to engage in a storyline.
Immersive cultural tourism is transforming the way people travel by offering in-depth exploration, interactive experiences and meaningful learning opportunities. It promotes tourism from the shallow focus on sightseeing to a complete engagement with culture and history. Additionally, it plays an irreplaceable role in promoting cultural heritage, sharing China’s stories, enhancing cultural confidence, and fostering cultural development, making it a vital part of the travel industry.

【推荐2】Coaches have always taken into account the condition of players when scheduling training sessions. Now with the help of artificial intelligence, they can calculate more precisely the probability that individual athletes will get injured during the next match, the next week or the next month.
“We follow a team for an entire season, recording GPS data during training and matches,” Rossi explains. He then uses machine learning to try to detect patterns. “This gives us the probability that a player will get injured in the next days or next weeks. ”
These data reveal an athlete’s workload—how often they train and how intensely. Just enough training can pave the way to medals, but too much puts pressure on the body and can lead to injuries.
Sport is gradually entering a new era, in which artificial intelligence might act as an assistant coach. Algorithms (算法) could enable a teenager to train smarter and avoid a career-ending injury, or help a professional athlete to compete for a few years longer. But the technology’s success depends, in part, on the ability of scientists to convince coaches to include data in their decision process.
The teams that McHugh has worked with have seen a reduction in injuries of between 5% and 40%. Yet not every coach is happy to join forces with AI. “Coaches sometimes don’t feel good, because it seems like trying to substitute the human element,”Rossi says. But in reality, data is only a tool. “The interpretation of the results, the change of the training load, is done by coaches,” he says.
McHugh agrees that people have to make the final call. “Once the injury probability for an athlete on a given day is output from an injury model, the athlete or coach must then decide whether the predicted risk is acceptable or not, usually depending on the context,” he says. There might be a big game that day, and the layer might be especially important to the learn. “Even though the predicted injury probability be as high as 70% , the coco may be willing to take that chance,” he says.

【推荐3】Never play games with a bot (机器人)—it will find a way to cheat if it can. A team from OpenAI, an artificial intelligence lab in San Francisco co-founded by Elon Musk, has developed artificially intelligent bots that taught themselves to cooperate by playing hide-and-seek. The bots also learned how to use basic tools and that disobeying the laws of physics can help to win.
In April, 2019, a team of bots known as the OpenAI Five beat the human world champions at the team-based video game Dota 2. The hide-and-seek bots use similar principles to learn but the simpler game allows for more inventive play.
Bowen Baker at OpenAI and his colleagues wanted to see if the team-based dynamics of the OpenAI Five could be used to create skills that could one day be useful to humans. The researchers set their bots loose in a simulated (模拟的) environment filled with fixed walls and movable boxes and left them to play team games of hide-and-seek millions of times. The bots each had their own view of the world and couldn’t communicate with each other directly. At first, the hiders simply ran away. However, they soon worked out that they could find objects in the environment to hide themselves from view. For example, they learned that boxes could be used to block doorways and build simple hiding places. The seekers learned that they could move a ramp (斜坡) around and use it to climb over walls. The bots then discovered that being a team player was the quickest way to win.
The hiders also learned to sabotage the other team, such as hiding the ramp before hiding themselves so that the other team can’t make use of the ramp. “Once one team learns a new strategy, it creates this pressure for the other team to adapt,” says Baker.
Such tricks show that AIs are able to find solutions that humans miss, says Baker. “Maybe they’ll even be able to solve problems that humans don’t yet know how to,” However, there’s still a long way to go from online hide-and-seek to real problem-solving.
