1 . Animal appear to predict earthquakes by sensing electricity in the air — the first study to find reliable evidence of the phenomenon has shown.
Cameras revealed an “amazing” drop in the number of animals up to 23 days before a major quake hit their rainforest home at Yanachaga National Park in Peru. Lead scientist Dr Rachel Grant, from Anglia Ruskin University, said, “The results showed that just before the earthquake, animals’ activity dropped right down.”
On a normal day the cameras placed around Yanachaga National Park record between 5 and 15 animals. But in the 23 days before the earthquake, the number of animals dropped to five or fewer per day. No animals were photographed at all on five of the seven days immediately before the quake.
Another study showed that animal activity remained normal in the park over a different period when seismic (地震的) activity was low. Co-author, professor Friedemann Freund, said, “The cameras were located at an altitude of 900 meters. If air ionization occurred, the animals would escape to the valley below, where there were fewer positive ions ( 离子). With their ability to sense their environment, animals can help us understand small changes that occur before major earthquakes.”
Other evidence suggested that before the earthquake, the air around the high mountain sites filled with positive ions that can be produced when rocks are placed under stress. Positive ions have been known to cause ill effects in humans as well as animals. Scientists believe the animals were made to feel uncomfortable by the positive ions, leading them to avoid the area. They are thought to have escaped to lower ground, where the air was less ionized. The findings may help experts develop better short-term seismic forecasts.

Dear Professor Williams,

Everyone has a hero — someone he admires, who has had an impact on his life. My brother, John, is my hero. He is the most sympathetic, sweet and funny person I have ever met. John is also mentally handicapped (智障的) and has a developmental disability known as autism (自闭症).
I used to be ashamed of John when I was little. When he first started talking, he had a hard time with pronunciation and understanding the meaning of words. He called me May-Me for most of my childhood because he could not pronounce Amy. As John grew older, his language ability gradually increased. I went from May-Me to Amy, and hammer burgers became hamburgers.
When I was younger, I was embarrassed by John. He used to run around in stores talking to himself, flicking his ears and putting his hands in his mouth. He had a hard time swallowing and would have drool (流口水) running down his face. John was very loud, and it seemed to me that he would always find the quietest moments to talk.
All I ever wanted was a normal brother. I would look at other brothers and sisters, see their relationships and turn green with envy. Why did my brother have to be so different? I was very self-conscious of what people thought. I felt as if the entire world was laughing at me because of the way John was acting. I was utterly offended at times that I could not have a normal brother.
The siblings of an autistic child can have many reactions to the amount of attention the autistic child receives. Some feel as if they are not receiving enough attention and may become superachievers to get their share. I hate to admit it, but I definitely fall into this category. I feel the need to excel (突出) in everything I do. I cannot help but think that this comes from having a disabled brother.
John has changed significantly over the past eighteen years.

5 . Why isn’t science better? Look at career incentives.
There are often substantial gaps between the idealized and actual versions of those people whose work involves providing a social good. Government officials are supposed to work for their constituents. Journalists are supposed to provide unbiased reporting and penetrating analysis. And scientists are supposed to relentlessly probe the fabric of reality with the most rigorous and skeptical of methods.
All too often, however, what should be just isn’t so. In a number of scientific fields, published findings turn out not to replicate (复制), or to have smaller effects than, what was initially claimed. Plenty of science does replicate — meaning the experiments turn out the same way when you repeat them — but the amount that doesn’t is too much for comfort.
But there are also ways in which scientists increase their chances of getting it wrong. Running studies with small samples, mining data for correlations and forming hypotheses to fit an experiment’s results after the fact are just some of the ways to increase the number of false discoveries.
It’s not like we don’t know how to do better. Scientists who study scientific methods have known about feasible remedies for decades. Unfortunately, their advice often falls on deaf ears. Why? Why aren’t scientific methods better than they are? In a word: incentives. But perhaps not in the way you think.
In the 1970s, psychologists and economists began to point out the danger in relying on quantitative measures for social decision-making. For example, when public schools are evaluated by students’ performance on standardized tests, teachers respond by teaching “to the test”. In turn, the test serves largely as of how well the school can prepare students for the test.
We can see this principle—often summarized as “when a measure becomes a target, it ceases to be a good measure”—playing out in the realm of research. Science is a competitive enterprise. There are far more credentialed (授以证书的) scholars and researchers than there are university professorships or comparably prestigious research positions. Once someone acquires a research position, there is additional competition for tenure (终身教授) grant funding, and support and placement for graduate students. Due to this competition for resources, scientists must be evaluated and compared. How do you tell if someone is a good scientist?
An oft-used metric (标准，度量) is the number of publications one has in peer-reviewed journals, as well as the status of those journals. Metrics like these make it straightforward to compare researchers whose work may otherwise be quite different. Unfortunately, this also makes these numbers susceptible to exploitation.
If scientists are motivated to publish often and in high-impact journals, we might expect them to actively try to game the system (钻空子). And certainly, some do—as seen in recent high-profile cases of scientific fraud (欺诈). If malicious (恶意的) fraud is the prime concern, then perhaps the solution is simply heightened alertness.
However, most scientists are, I believe, genuinely interested in learning about the world, and honest. The problem with incentives is that they can shape cultural norms without any intention on the part of individuals.

“Will you do me a favor, Achenyo?” Mama called as she looked up from her weaving. Beside her was a pile of wild-grass stalks (秆). Mama took a stalk, laid it along the length of the half-finished bag, and began to weave (编织). In the corner were pots of dyes (染料) she’d use to paint the finished bags. “Will you get me some water for the dyes?” “Of course, Mama!” Achenyo picked up a pot as she ran outside. She didn’t like weaving, although it was a tradition for a mother to pass on the trade to her daughter. Outside, Achenyo called to her neighbor Ajuma. Both girls, with pots balanced on their heads, made their way to the river.
Achenyo and Ajuma soon arrived at the water’s edge, and they found a huge surprise. The river was gone! In its place was a blanket of dark green leaves and lavender-colored (淡紫色的) flowers. “Oh no!” Achenyo cried. “Mama won’t have water to mix the dyes for her bags.” When the adults arrived at the riverbank, they shook their heads, saying “They’ve struck again!”
Last year, the rainy season had brought an invasion (入侵) of water hyacinths. The plants had covered the river and left no room to dip a pot to get water. And now they were back. The adults walked into the water. They began pulling up water hyacinths and throwing them onto the riverbank. When they’d cleared enough plants, the girls filled their pots with water. A pile of water hyacinths lay on the riverbank. What a shame to waste such pretty flowers, Achenyo thought. She picked some for Mama, and then the girls headed home. Each day, they found the river covered by water hyacinths as if no one had cleared the waterfront (水边地) the day before. To fill their pots, they again had to pull up and throw water hyacinths onto the riverbank. The pile on the sand grew taller.
One day, as Achenyo moved an armful of dried water hyacinths out of her way, she had an idea. Carrying the plants under her arm, she ran home.

8 . Mental Health Crisis Among Teens Demands a New Approach
Since the CDC released its survey results last month showing alarmingly high rates of sadness and depressive thoughts among teens, fingers have been pointed from two sides at the causes of this crisis.
According to the CDC’s findings, more than one in five of the 17,000 high school students surveyed reported mental breakdown. Their rates of sadness and hopelessness are the highest in a decade, reflecting an increasing trend exacerbated by society’s isolation(隔离)and stress.
Parents as well as teachers and others who have direct contact with children must accept this preventive approach. It is crucial that they not be afraid to ask direct questions about depressive thoughts.
| A．And they should resist the false idea that raising a question creates a risk that was not there before. |
| B．This means that we must put aside our disagreements and approach this issue as a matter of life and death. |
| C．Some have argued that the climate issue has created an existential threat and accompanying anxiety. |
| D．Hospitalization may also be appropriate when the person in question shows an immediate danger to themselves. |
| E．At the macro(宏观的)level, our country can do so much more to help people struggling with mental health problems and their families. |
| F．It’s time to stop blaming and turn our attention to this generation of struggling teenagers. |
| G．It’s time for those who have the power to amplify(放大)their voices and drive change to focus on helping teenagers and families access the help they need. |
9 . 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.
