1 . When John Todd was a child, he loved to explore the woods around his house, observing how nature solved problems. A dirty stream, for example, often became clear after flowing through plants and along rocks where tiny creatures lived. When he got older, John started to wonder if this process could be used to clean up the messes people were making.

After studying agriculture, medicine, and fisheries in college, John went back to observing nature and asking questions. Why can certain plants trap harmful bacteria (细菌)? Which kinds of fish can eat cancer-causing chemicals? With the right combination of animals and plants, he figured, maybe he could clean up waste the way nature did. He decided to build what he would later call an eco-machine.

The task John set for himself was to remove harmful substances from some sludge (污泥). First, he constructed a series of clear fiberglass tanks connected to each other. Then he went around to local ponds and streams and brought back some plants and animals. He placed them in the tanks and waited. Little by little, these different kinds of life got used to one another and formed their own ecosystem. After a few weeks, John added the sludge.

He was amazed at the results. The plants and animals in the eco-machine took the sludge as food and began to eat it! Within weeks, it had all been digested, and all that was left was pure water.

Over the years, John has taken on many big jobs. He developed a greenhouse — like facility that treated sewage (污水) from 1,600 homes in South Burlington. He also designed an eco-machine to clean canal water in Fuzhou, a city in southeast China.

“Ecological design” is the name John gives to what he does. “Life on Earth is kind of a box of spare parts for the inventor,” he says. “You put organisms in new relationships and observe what’s happening. Then you let these new systems develop their own ways to self-repair.”

2 . Thanks to in-depth reporting by the Wall Street Journal, we now know that Facebook has long been aware its product Instagram has harmful effects on the mental health of many adolescent users. Young girls, in particular, struggle with their body image thanks to a constant stream of photos and videos showing beautiful bodies that users don’t think they can attain.

While the information the Journal covered is essential and instructive, it does not tell the whole story. Deep down, this is not an Instagram problem; it’s a people problem. Understanding that distinction can make the difference between a failed attempt to contain a teen’s interest in an addictive app and successfully addressing the underlying problem leading to mental distress induced (诱发) by Instagram.

Critics were quick to shame Facebook for sitting on the data and not releasing it to researchers or academics who asked for it. Others criticize the social media giant for not using the research to create a safer experience for its teen users. The anger, while understandable, is misplaced.

While I’m reluctant to defend Facebook, I’m not sure it’s reasonable to blame the company for withholding data that would hurt its business. Have you ever binge-watched (狂看) a Netflix series? I assure you it wasn’t a healthy endeavor. You were in active, likely did nothing productive, mindlessly snacked and didn’t go outside for fresh air. It is an objectively harmful use of time to stare at a TV or laptop for a full weekend. Should we respond by shaming Netflix for not alerting us to how damaging an addictive product can be?

While it’s reasonable to say Instagram makes esteem issues worse, it strains credulity (夸张到难以置信) to believe it causes them in the first place. You create your own experiences on social media. For the most part, you choose which accounts to follow and engage. If you’re already vulnerable to insecurities and self-sabotage (自损) — as many teens are — you will find accounts to obsess over. And this isn’t a new phenomenon.

Before social media, there were similar issues fueling self-esteem issues. Whether the target be magazines, movies or television shows depicting difficult-to-attain bodies, there has been a relatively steady chorus (异口同声) of experts nothing the damage new media could cause young viewers.

Self-esteem issues have an underlying cause — one that’s independent of social media use. Instagram merely enhances those feelings because it provides infinitely more access to triggers than older forms of media. It’s more worthwhile to address those underlying factors rather than to attack Facebook.

Microsoft bakes ChatGPT-like tech into search engine Bing

Microsoft is baking ChatGPT-like technology into its search engine Bing,     1     (transform) an Internet service that lags far behind Google into a new way of communicating with AI.

Though the new version is now limited to desktops and has no interface for smartphones,     2     most people now access the Internet, Mehdi, a Microsoft executive, has said that the technology will scale to millions of users in coming weeks and come to the smartphone apps.

The improvement may give the software giant a cutting edge     3     other tech companies in capitalizing on the worldwide excitement surrounding ChatGPT, a tool that     4     (awaken) millions of people to the possibilities of the newest AI technology in the past few weeks.

Aside from it, Microsoft is also integrating the chatbot technology into its Edge browser. “Think of it as faster, more accurate, more powerful technology     5     (tune) for search queries”, said Mehdi.

The shift to making search engines more conversational — able to confidently answer questions     6     offer links to other websites — could change the advertising-fueled search business, but also poses risks if the AI systems don’t get their facts right. Their opaqueness (不透明性) also makes it hard to source back to the original human-made images and texts,     7     the new Bing includes notes that reference the source data.

“Bing is powered by AI, so surprises and mistakes are possible. Make sure to check the facts.” is a message that appears at the bottom of the preview version of Bing’s new homepage. As an example of how it works, Mehdi     8     (quiz) it on 1990s-era rap, showing its ability to distinguish between the song “Jump” and “Jump Around”. He also used it to show how it could plan a vacation or help with shopping.

Google has been cautious about such moves. But in response to pressure due to ChatGPT’s popularity, Google announced on Monday a new conversational service named Bard that will be available to a group of “trusted testers” before     9     (release) globally this year.

Chinese tech giant Baidu also announced a similar search chatbot coming later this year. Other tech rivals such as Meta and Amazon have been researching similar technology, but Microsoft’s latest moves aim to position     10     at the center of the ChatGPT zeitgeist (时代潮流).

Wikipedia has come a long way since it started in 2001. With around 70, 000 volunteers editing in over 100 languages, it is by far the world’s     1    (popular)reference site. However, its future is uncertain.

One of the biggest threats it faces is the rise of smartphones     2    the dominant personal computing device. Wikipedia has always depended on contributors (撰稿人) who hunch over keyboards    3    (search) for references, discussing changes and writing articles with a special code. It’s simply too hard to use complex code on a tiny screen. The pool of potential Wikipedia editors    4    dry up as the number of mobile users keeps growing. The nonprofit Wikimedia Foundation,     5    oversees(监督) Wikipedia’s operations,     6    (look) for solutions for a while. For instance, the development of touch-screen tools allows editors to sift through (筛选)information and share content from their phones.

The tension runs through the community. Last year, the foundation took unprecedented steps of forcing the installation of new software on the German-language Wikipedia. The German editors    7    (show) their independence by resisting an earlier update to the site’s user interface(界面).     8    the wishes of these experienced editors, the foundation installed a new method for viewing multimedia content and then set up a “superprotect” feature     9    (prevent) stubborn administrators from changing it back.

Could the pressure from mobile users, and the internal tension, tear Wikipedia apart? A world without it seems unimaginable, but consider the fate of other online communities. Blogging, celebrated a decade ago as pioneering an exciting new form of personal writing, has decreased significantly in the social-media age.

These are challenges, but they can still    10    (solve). There is no other significant alternative to Wikipedia, and good will toward the project could hardly be higher. In an age of internet giants, the selflessness of websites is worth saving.

Modern media is awash in advertising clutter(杂乱), and who’s to blame? Modern audiences that hate conventional full-length and full-size ads.

Today’s consumers don’t like to pay for content, which ought to create a rich environment for advertisers. Yet these same consumers are prone to click or turn away when a conventional ad appears. The result is ad clutter.

YouTube     1    a combination of full-length ads, skippable ads, lower-screen banners and display ads on the page alongside each video. Newspapers that once considered the front page important now     2    run ads there.

Advertisers integrate plugs(推销) into content to frustrate digital video recorders, which allow viewers to watch programs on a delay and skip regular commercials. If you watch regional telecasts of baseball games, the commercial clutter is so     3    . Ads are visible on the stadium wall behind the home-plate umpire(裁判). On-screen graphics include sponsor logos. And everything is a paid plug--“This call to the coach’s zone is brought to you by Verizon.”

According to the showbiz paper Variety, several streaming services are about to introduce a new twist: commercials that start running whenever a viewer pauses a program. Hulu intends to launch such ads this year. AT&T’s DirecTV and U-verse units will     4    use similar technology to trigger full-motion commercials whenever a viewer tries to take a break.

There’s a lot at stake. According to Variety, National Football League(NFL) TV broadcasts generate an estimated $4.35 billion in ad revenue during the 17-week regular season. NFL     5    are now loaded with mini commercials that pop up when there is a brief pause in the action, often in “double boxes” that show a view of the field in one frame and a(n)    6    in the other.

Interestingly, with no “screen” to work with, radio is one medium that has tried for some time to buck the trend. Many commercial stations trade clutter for clusters--that is, a solid block of commercials running five minutes or more, followed by lengthy commercial-free     7    of time.

But wherever a screen is involved, or a printed page, ad clutter is     8    everywhere. Programmers and advertisers can’t really be expected to limit this; it’s a fact of business. Consumers, on the other hand, can opt for commercial-free content--if they’re willing to pay for it.

But getting limitless content without paying while also being     9    heavy advertising intrusions is impossible. As media environment is permanently cluttered, audiences should be     10    with what they wish for.

7 . Given the buzz it’s created, there’s a good chance you’ve heard about ChatGPT. It’s an interactive chatbot powered by machine learning. The technology has basically devoured the entire Internet, reading the collective works of humanity and learning patterns in language that it can recreate. All you have to do is give it a prompt (提示), and ChatGPT can do an endless array of things: write a story in a particular style, answer a question, explain a concept, compose an email—write a college essay-and it will spit out coherent, seemingly human—written text in seconds. The technology is both awesome and terrifying.

22-year-old Edward Tian is working feverishly on a new app to combat misuse of ChatGPT.

Over the last couple years, Tian has been studying an AI system called GPT-3, a predecessor to ChatGPT that was less user-friendly and largely inaccessible to the general public because it was behind a paywall. As part of his studies this fall semester, Tian researched how to detect text written by the AI system while working at Princeton’s Natural Language Processing Lab.

Then, as the semester was coming to a close, OpenAI, the company behind GPT-3 and other AI tools, released ChatGPT to the public for free. For the millions of people around the world who have used it since, interacting with the technology has been like getting a peek into the future; a future that not too long ago would have seemed like science fiction.

For many users of the new technology, wonderment quickly turned to alarm. How-many jobs will this kill? Will this empower nefarious (恶意的) actors and further corrupt our public discourse (公共话语)? How will this disrupt our education system? What is the point of learning to write essays at school when AI-which is expected to get exponentially better in the near future-can do that for us?

Tian had an idea. What if he applied what he had learned at school over the last couple years to help the public identify whether something has been written by a machine?

Tian already had the know-how and even the software on his laptop to create such a program. Ironically, this software, called GitHub Co-Pilot, is powered by GPT-3. With its assistance, Tian was able to create a new app within three days. It’s a testament to the power of this technology to make us more productive.

On January 2nd, Tian released his app GPTZero. It basically uses ChatGPT against itself, checking whether “there’s zero involvement or a lot of involvement” of the AI system in creating a given text.

When Tian went to bed that night, he didn’t expect much for his app. When he woke up, his phone had blown up. He saw countless texts and DMs from journalists, principals, teachers, you name it, from places as far away as France and Switzerland. His app, which is hosted by a free platform, became so popular it crashed. Excited by the popularity and purpose of his app, the hosting platform has since granted Tian the resources needed to scale the app’s services to a mass audience.

8 . Climate experts have warned about the many ways a warming planet can negatively affect human health. ________ global temperatures are predicted to increase by 1.5℃ by the 2030s, that risk is becoming increasingly real.

One long-held prediction that appears to be coming true — according to the results of a study recently published in Nature Scientific Reports — is how climate change might enhance ________ of bacteria that thrive and spread through warm sea waters and cause an infection with a particularly high ________ rate.

Vibrio vulnificus (创伤弧菌) flourishes in salty or brackish waters above 68℉. Infections are currently rare in the U.S., but that’s likely to change. Using 30 years of data on infections, scientists at the University of East Anglia in the U.K. found that Vibrio vulnificusis ________ from its historic Gulf Coast range, with more Northern states reporting infections as waters become warmer.

“We’re seeing the core ________ of infections extending to areas that traditionally have very few and very rare cases,” says Elizabeth Archer, a Ph.D. researcher and ________ author of the study. “But these areas are now coming into the main area of infections.”

Based on the latest data on how much the world’s water and air temperatures will rise, the scientists predict that by 2081, Vibrio vulnificus infections could reach every state along the U.S. East Coast. Currently, only about 80 cases are reported in the U.S. each year; by 2081, that could go up to over three-fold, the authors say.

Such a proliferation could have serious health consequences. Vibrio vulnificus kills approximately 20% of the healthy people it infects, and 50% of those with weakened immune systems. There is little evidence that antibiotics can ________ the infection, but doctors may prescribe them in some cases. People can get infected either by eating raw shellfish like oysters or by exposing small ________ to waters where the bacteria live, which can lead to serious skin infections.

Warming sea temperatures aren’t the only reasons behind the rise of Vibrio vulnificus. Hotter air also draws more people to the coasts and bays, bringing them into closer contact with the bacteria.

“The bacteria are part of the natural marine environment, so I don’t think we can ________ it from the environment,” says Archer. “It’s more about mitigating infections by increasing ________ of the risk.”

To alert people to the growing threat, ________ systems are needed to track when concentrations of bacteria start to rise, similar to currently available pollen and pollution alarm.

Vbrio vulnificus is so ________ to temperature changes that concentrations could bloom after even a day of warmer water, so consistent monitoring and alerts are critical, says Iain Lake, professor of environmental epidemiology at University of East Anglia and senior author of the paper.

Lake says the expansion of Vibrio vulnificus is concerning for public health since the bacteria are now invading waters closer to heavily ________ areas, such as New York and Philadelphia. “Everyone can get a Vibrio vulnificus infection,” he says. “But the more ________ there is between warmer waters and people, the more the bacteria can move into populations ________ the elderly and those with other health conditions, who are more vulnerable to infections.”

9 . The next morning Alex was waiting in the FMA president’s suite when Jerome Patterton arrived. Alex filled him in quickly on the Jax report. Then he said, “I want you to give an order to the trust department to sell every share of Supranational we’re holding.”

“I won’t!” Patterton’s voice rose. “Who do you think you are, giving orders---“ “I’ll tell you who I am, Jerome. I’m the guy who warned the board against in-depth involvement with SuNatCo. I fought against heavy trust department buying of the stock, but no one---including you ---would listen. Now Supranational is caving in.” Alex leaned across the desk and slammed a fist down hard. “Don’t you understand? Supranational can bring this bank down with it.”

Patterton was shaken. “But is SuNatCo in real trouble? Are you sure?”

“If I weren’t, do you think I’d be here? I’m giving you a chance to salvage something at least.” He pointed to his wristwatch. “It’s an hour since the New York stock market opened. Jerome, get on the phone and give that order!”

Muscles around the bank president’s mouth twitched nervously. Never decisive, strong influence often swayed him. He hesitated, then picked up the telephone.

“Get me Mitchell in the trust department… Mitch? This is Jerome. Listen carefully. I want you to give a sell order immediately on all the Supranational stock we hold… Yes, sell every share.” Patterton listened, then said impatiently, “Yes, I know what it’ll do to the market. And I know it’s irregular.” His eyes sought Alex’s for reassurance. The hand holding the telephone trembled as he said, “There’s no time to hold meetings. So do it! Yes, I accept responsibility.”

He hung up and reached for a glass of water. “The stock is already down. Our selling will depress it more. We’ll be taking a big beating.”

“It’s our clients---people who trusted us---who will take the beating. And they’d have taken a bigger one still, if we’d waited. Even now we’re not out of the woods. A week from now the SEC may disallow those sales. They may rule we had inside knowledge that Supranational was about to be bankrupt, which we should have reported and which would have halted trading in the stock.

10 . There was a time not long ago when new science Ph.D.s in the United States were expected to pursue a career path in academia (学术界). But today, most graduates end up working outside academia, not only in industry but also in careers such as science policy, communications, and patent law. Partly this is a result of how bleak the academic job market is, but there’s also a rising awareness of career options that Ph.D. scientists haven’t trained for directly—but for which they have useful knowledge, skills, and experience. Still, there’s a huge disconnect between the way we currently train scientists and the actual employment opportunities available for them, and an urgent need for dramatic improvements in training programs to help close the gap. One critical step that could help to drive change would be to require Ph.D. students and postdoctoral scientists to follow an individual development plan (IDP).

In 2002, the U.S. Federation of American Societies for Experimental Biology recommended that every postdoctoral researcher put together an IDP in consultation with an adviser. Since then, several academic institutions have begun to require IDPs for postdocs. And in June, the U.S. National Institutes of Health (NIH) Biomedical Research Workforce Working Group recommended that the NIH require IDPs for the approximately 32,000 postdoctoral researchers they support. Other funding agencies, public and private, are moving in a similar direction.

IDPs have long been used by government agencies and the private sector to achieve specific goals for the employee and the organization. The aim is to ensure that employees have an explicit tool to help them understand their own abilities and aspirations, determine career possibilities, and set (usually short-term) goals. In science, graduate students and new Ph.D. scientists can use an IDP to identify and navigate an effective career path.

A free Web application for this purpose, called myIDP, has become available this week. It’s designed to guide early-career scientists through a confidential, rigorous process of introspection（内省）to create a customized career plan. Guided by expert knowledge from a panel of science-focused career advisers, each trainee’s self-assessment is used to rank a set of career trajectories（轨迹）. After the user has identified a long-term career goal, myIDP walks her or him through the process of setting short-term goals directed toward accumulating new skills and experiences important for that career choice.

Although surveys reveal the IDP process to be useful, trainees report a need for additional resources to help them identify a long-term career path and complete an IDP. Thus, myIDP will be most effective when it’s embedded in larger career-development efforts. For example, universities could incorporate IDPs into their graduate curricula to help students discuss, plan, prepare for, and achieve their long-term career goals.
