2 . Both misinformation, which includes honest mistakes, and disinformation, which involves an intention to mislead, have had a growing impact on teenage students over the past 20 years. One tool that schools can use to deal with this problem is called media literacy education. The idea is to teach teenage students how to evaluate and think critically about the messages they receive. Yet there is profound disagreement about what to teach.

Some approaches teach students to distinguish the quality of the information in part by learning how responsible journalism works. Yet some scholars argue that these methods overstate journalism and do little to cultivate critical thinking skills. Other approaches teach students methods for evaluating the credibility of news and information sources, in part by determining the incentive of those sources. They teach students to ask: What encouraged them to create it and why? But even if these approaches teach students specific skills well, some experts argue that determining credibility of the news is just the first step. Once students figure out if it’s true or false, what is the other assessment and the other analysis they need to do?

Worse still, some approaches to media literacy education not only don’t work but might actually backfire by increasing students’ skepticism about the way the media work. Students may begin to read all kinds of immoral motives into everything. It is good to educate students to challenge their assumptions, but it’s very easy for students to go from healthy critical thinking to unhealthy skepticism and the idea that everyone is lying all the time.

To avoid these potential problems, broad approaches that help students develop mindsets in which they become comfortable with uncertainty are in need. According to educational psychologist William Perry of Harvard University, students go through various stages of learning. First, children are black-and-white thinkers—they think there are right answers and wrong answers. Then they develop into relativists, realizing that knowledge can be contextual. This stage is the one where people can come to believe there is no truth. With media literacy education, the aim is to get students to the next level—that place where they can start to see and appreciate the fact that the world is messy, and that’s okay. They have these fundamental approaches to gathering knowledge that they can accept, but they still value uncertainty.

Schools still have a long way to go before they get there, though. Many more studies will be needed for researchers to reach a comprehensive understanding of what works and what doesn’t over the long term. “Education scholars need to take an ambitious step forward,” says Howard Schneider, director of the Center for News Literacy at Stony Brook University.

3 . Human beings have somehow managed to engineer the night to receive us by filling it with light. This kind of control is no different from the feat ( 壮 举 ) of damming a river. Its benefits come with_________ — called light pollution — whose effects scientists are only now beginning to study. Light pollution is largely the result of bad lighting design. _________ lighting washes out the darkness of night, altering light levels and light rhythms to which many forms of life, including ourselves, have_________. Wherever man-made light spills into the natural world, some aspects of life-migration, reproduction, feeding-is affected.

For most human history, the phrase “light pollution” would have_________. Imagine walking towards London on a moonlit night around 1800, when it was Earth’s most populous city. Nearly a million people lived there, _________ candles, torches and lanterns, as they always had. Only a few houses were lit by gas, and there would be no public gaslights in the streets or squares for another seven years. From a few miles away, you would have been more likely to_________ London than to see its dim collective glow.

We’ve lit up the night as if it were a(n) _________ country. As a matter of fact, among mammals (哺乳动物) alone, the number of species active at night is astonishing. Light is a powerful biological force, and on many species it acts as a magnet attracting them to it. The effect is so powerful that scientists speak of songbirds and seabirds being_________ by searchlights on land or by the light from gas flares on marine oil platforms, circling and circling in the thousands until they drop.

It was once thought that light pollution only affected astronomers, who need to see the night sky in all its glorious clarity. Unlike astronomers, most of us may not need a_________ view of the night sky for our work. __________, like most other creatures, we do need darkness. __________ darkness is pointless. It is as essential to maintaining our biological welfare as__________ itself; the price of modifying our internal clockwork means it doesn’t operate as it should, causing various physical discomforts. So fundamental are the regular rhythms of waking and sleep to our being that__________ them is similar to altering our center of gravity.

In a very real sense, light pollution causes us to__________ our true place in the universe, to forget the scale of our being, which is best__________ against the dimensions of a deep night with the Milky Way — the edge of our galaxy — arching overhead.

4 . A huge crowd has gathered to watch China’s new scientific research ship enter the water for the first time. This ship, equipped with on-board labs and the latest scientific kit, will eventually explore the world’s oceans. But it is also going to help China plunge beneath the waves: it will serve as a launch-pad for submarines that can dive to the deepest parts of the ocean. “Humans know much less about the deep oceans than we know about the surface of the Moon and Mars. That’s why I want to develop the facility for ocean scientists to reach the deep seas,” says Prof. Cui Weicheng.

He is the dean of deep sea science at Shanghai Ocean University but he has also set up a private company called Rainbow Fish, which built the new research ship and is busy developing submersibles. One of its unmanned subs reached a depth of 4,000m (13,000ft) in its most recent trial. But Rainbow Fish’s ultimate goal is manned exploration and it plans to take humans to the very bottom of the ocean the Mariana Trench, in the Pacific, at a depth of nearly 11,000m (36,000ft). He shows me around a life-size model of the submarine and explains that there is room inside for a crew of three, who will be protected by a thick metal sphere.”At the moment, we are in the design stage, so we are testing several extremely high-strength materials for it.” It will have to bear immense pressures from the crushing weight of water above. If there are any weaknesses, the submarine will implode. The deepest ocean is a place few people have ever experienced first-hand. The first dive to the Mariana Trench was carried out in 1960 by US Navy Lieutenant Don Walsh and Swiss engineer Jacques Picard. Their vessel, the Bathyscaphe Trieste, creaked and groaned as it made the descent, taking nearly five hours.

The only other manned expedition was carried out by Hollywood director James Cameron, who took a solo plunge in a bright green submarine in 2012. Rainbow Fish wants its sub to be next. The team insists its venture isn’t about politics and that it is looking to collaborate with American, Russian and European scientists. It is, though, a commercial operation. The company plans to charge people to use its research ship and submarines, and is targeting three groups, says managing director Dr. Wu Xin. “The first is definitely the scientists who are interested in studying deep-sea science and technology. The second group is offshore companies and oil companies. The last one is tourists and adventurers [who] want to go down themselves to have a look at what’s going on there,” he says. This kind of entrepreneurial approach may be a new model for science in China. Deep-sea research is a difficult, high-risk activity — and much of the ocean remains unexplored. But Cui, who hopes to be the first Chinese person to reach the Mariana Trench, believes that China could be the nation to truly open up this final frontier.

7 . Top Exhibitions to See in London in 2023

Architectural: Vanishing Points

While we like to think of architecture existing purely in the real world, emerging designers and architects are using platforms like Instagram to create structures in the virtual world. This collection of works, which range from the practical to the fantastical, are all by architects who have gathered significant social media followings.

In the Digital Universe at ROCA London. 8 February—31 July, free.

Flowery: Orchids

This annual festival is back in bloom (开花), this time inspired by the beauty and biodiversity of Cameroon. Just like previous years, the orchids are spread throughout the various zones of the Princess of Wales conservatory and accompanied by sculptures that are just as colourful as the flowers on display.

At Kew Gardens. 4 February —5 March, &16.50—entrance to the gardens included.

Female Abstraction: Action, Gesture, Paint

Art history has often shone a light on the men of Abstract Expressionism, such as Jackson Pollock and Mark Rothko. Well, now’s the time to let the most important women of the movement take the limelight in an exhibition that includes works by American artists such as Lee Krasner and Helen Frankenthaler, but spreads the net wider to include the female abstract artists from Europe, Asia and the wider world, with whom most of us will be unfamiliar.

At Whitechapel Gallery. 9 February—7 May, £ 16.50—concessions available.

Powerful Portraits (肖像): Alice Neel

The largest UK exhibition to date of American painter Alice Neel’s work will bring together her figurative pieces from across her 60-year career. Neel went against the popular grain by painting figures when abstract works were most popular, and she painted subjects that other artists ignored — pregnant women, labour leaders, black children, civil rights activists and strange performers. It’s high time we had a major show of her work in London, and the Barbican has duly provided.

At Barbican Art Gallery. 16 February—21 May, & 18.

8 . On a dark night, 11-year-old Joe was playing hide-and-seek with his friends in the backyard when he thought he saw Magellan—a huge housecat. However, when the cat suddenly jumped on his head, Joe found it turned out a young cougar. He backed away from the animal, then turned and ran inside the house.

Cougar encounters like this one are becoming increasingly common in the U.S. Most people assume that’s because cougar populations are growing, or because the big cats are coming into closer contact with the expanding web of human suburbs. But Professor Robert Wielgus at Washington State University argues that poorly designed hunting policies might be causing an increase in cougar-human conflicts.

Wielgus’s research teams have been fitting the big cats with radio collars and monitoring their movements. They find that the cougar population is actually declining rapidly and almost no male cougars are over four years of age. And a study shows that the heavily hunted area has five times as many cougar complaints as the lightly hunted area—even though the density of cougars is about the same in both areas.

Wielgus suspects that hunting policies, which allow older males to be killed to keep cougar populations in check, were the culprit and teenage cougars in the heavily hunted area may be responsible for most of the trouble. To test his theory, he adds two more groups of cougars to the tracking program—one in a heavily hunted area and another in a comparable but lightly hunted area. He concludes that heavy hunting indeed almost wipes out older males and the population structure in the heavily hunted area shifts toward younger animals.

With these findings, Wielgus believes without adults to keep them under control, the disorderly teens are more likely to come into conflict with humans, farm animals and pets.

Wielgus’s ideas don’t sit well with everyone. “Hunting definitely does cause lots of teenage males to flow in, but I don’t yet see solid proof that they are more likely to cause trouble than older cats,” says the University of Montana’s Robinson. “In many cases, the new arrivals have been squeezed out of remote wilderness habitat and forced into areas where they are more likely to encounter humans. I think humans are primarily responsible for all the interaction you see. We’re moving into these areas where cougars and deer are,” according to Alldredge, a researcher at the Colorado Division of Wildlife.

We may not understand what makes 18-year-old males more likely than 48-year-old men to do dangerous things, Wielgus says, but we know that the world would be a different place, if teenagers were in charge.
