2 . Autonomously copying other people’s thoughts or options or simply going with the crowd is often referred to as “herd (群体) behaviour”. Herding can appear to make a lot of sense. In an earlier article, I discussed the so-called “wisdom of crowds”, which suggests that average judgments of large groups of people often outperform individual choices.
Psychology research has attempted to model herd behaviour and suggests that the phenomenon relies on the existence of social connections or patterns between individuals as well as specific mechanisms of passing on information. A key condition is the human ability to “mentalize”, which means being able to read and interpret someone else’s mental state and using the information to explain their options. This action of mentalizing is responsible for people’s tendency to attach meaning to options by the herd, even if many behaviours may have come about at random.
Herd behaviours, while common and easy to explain, hold significant dangers. Contrary to the so-called “wisdom of crowds”, which emerges when the judgments of individual group members are independently collected to produce an average opinion, herd behaviours typically rely on so-called “information cascades”, where people take on others’ beliefs or copy their options without critically evaluating the underlying reasons. This frequently leads to the mirroring of unreasonable or stupid behaviours.
Blindly following the herd can be dangerous. So how can we resist the tendency of following the crowd? The sad news is that psychology research suggests that it’s surprisingly difficult to withstand the influences of the herd. In an experiment, researchers found that warning messages about the potential errors of the crowd were surprisingly ineffective in helping subjects make better choices. It appears there is no quick and easy fix. Instead, long-term attitude changes may be necessary, which could involve individuals adopting more critical approaches towards their peers’ opinion, and questioning others’ behaviours as opposed to blindly following them.

3 . Shakespeare described sleep as “the main course in life’s feast, and the most nourishing”. New research suggests it may also be a key nutrient in defend us against Alzheimer’s disease.
Poor sleep has long been linked to Alzheimer’s, but the relationship is similar to the chicken-and-egg puzzle. It isn’t clear which came first. During deep sleep, the brain produces slow electrical waves and flushes out neurotoxins (神经毒素) including amyloid (淀粉样蛋白) and tau (微管蛋白) , two indicators of the disease.
Studies have shown that even one night of terrible deep sleep can lead to an increase of amyloid. A week of disrupted sleep can raise the amount of tau, which is especially insidious because over time it can strangle neurons from the inside out.
A study in the Annals of Neurology found that a sleep pill called suvorexant could reduce amyloid and tau in middle-aged adults with no cognitive problems. The two-night trial showed that amyloid dropped 10%to 20%, and a key form of tau 10%to 15%in people who received a high dose compared to a placebo (安慰剂) group. But these effects need to be studied over longer periods of time—including in older adults at higher risk of Alzheimers. But the study suggests that improving sleep quality among middle-aged adults could help reduce the risk of developing Alzheimer’s later in life.
What has puzzled neurologists, however, is that some people with high levels of amyloid who may appear to have Alzheimer’s based on brain scans nonetheless function normally. Neurologists assume that this is because some people have higher levels of “cognitive reserve.” which enables them to function normally despite neurological damage. But there’s another X factor, which scientists have struggled to identify. A new study suggests it may be sleep, and in particular deep sleep.
“Think of deep sleep almost like a life raft that keeps memory afloat, rather than memory getting dragged down by the weight of Alzheimer’s disease,” says Matthew Walker, a neuroscience professor at UC Berkeley.

5 . A professor at the University of South Florida recently published a paper she knew barely anyone would read. At least, not outside her field. The paper had to do with the impact of algae (海藻) blooms and depletion (退化) of coral reefs on the region’s tourism industry.
The work of completing the paper was glum, says Heather O’Leary. It involved tracking visitors’ reactions to the environment on social media. “Part of the data for months was just reading posts: dead fish, dead fish, dead fish,” she recalled. “We were really thinking every day about the Gulf of Mexico and the waters that surround us, about those risks, and the risks to our coastal economy.”
O’Leary wanted people to pay attention to her paper and raise their environmental awareness. But she couldn’t come up with any solutions. However, attending concerts at USF’s School of Music inspired and gladdened her. She reached out to its director of bands, Matthew McCutchen. “I’m studying climate change and what’s going down at the coral reefs,” he remembered her saying. “And I’ve got all this data from my paper and I’d like to know if there’s any way that we can turn it into music. So people can know about my paper.”
Indeed there was. Composition professor Paul Reller worked with students to map pitch, rhythm and duration to the data. It came alive, O’Leary said, in ways it simply couldn’t be done on a spreadsheet.
“My students were really excited to start thinking about how students from other majors, such as the music students, heard patterns that they did not normally hear in some of the repetitions,” she said. In this case, she said, the patterns revealed the economic impact of pollution on coastal Florida communities.
With music, she added, “you can start to sense with different parts of your mind and your body that there are patterns happening and that they’re important.” “The world is going to see more and more of these ‘wicked problems’, the ones that take multiple people with different types of training and background to solve.”
Now,a group of professors and students are working to bring together music and the environment in related projects, such as an augmented (增强的) reality experience based on this composition. The group wants to spread awareness about the algae blooms, data literacy (数据认知) and environmental protection.

6 . How to Make Your Writing Flow?
Writing flow refers to how smoothly text flows from one sentence to the next and one paragraph to another.
1. Vary your sentence structure.
Using only short, choppy sentences creates a disconnected rhythm that disrupts the flow, while a series of long, complex sentences overwhelm readers.
2. Use transition words and phrases.
Transition words and phrases act like bridges between sentences and paragraphs. They create logical connections between ideas. Use transitions like “however,” “therefore,” “similarly,” and “in contrast” to glue sentences and paragraphs together smoothly.
3. Structure paragraphs around a central idea.
4.
Revisiting writing with fresh eyes makes flaws in flow and transitions more noticeable. Let your drafts rest for a day or two to prevent getting stuck reworking the same passage repeatedly. Approaching writing anew allows you to evaluate flow and smooth out imperfections with distance and objectivity.
A.Don’t leave out the revising process. |
B.Let completed drafts rest before editing. |
C.The key is to mix sentence lengths to create fluid variety. |
D.Place them at the beginning of a sentence or between independent clauses. |
E.Flowing writing maintains the continuity of ideas and transitions logically. |
F.Each paragraph should have a controlling idea relating to your overall theme. |
G.As a writer, it is your responsibility to present your readers with a central idea. |
7 . Do you feel like there are too many things to do in a day, but not enough time to do them? If so, you’re experiencing what researchers call time poverty.
If you want a satisfying social life, buy time for it. You might pay to have a disliked housework done by others, get a direct flight instead of a cheaper one with a stopover, or pay extra to drive the fastest route home.
Another way to get more time is to give it away. In one study, researchers asked people to devote part of their Saturday morning to doing something for themselves that they weren’t already planning to do or doing something for someone else. The people who gave away their time later felt like they had more of it.
If you have too many things to do and not enough time to do them, try to cut back on some things.
A.Time poverty is a sign of the times |
B.Helping others expands our sense of time |
C.Buying time is a good way to free you from the boredom of repeated tasks |
D.The choices we make with our time greatly affect our happiness and social lives |
E.Then invest your free time in something socially engaging |
F.You don’t have to keep up with the pace of the modern world |
G.Yet, feeling short on time is associated with lower level of happiness and connection |
