1 . On a September afternoon in 1940, four teenage boys made their way through the woods on a hill overlooking Montignac in southwestern France. They had come to explore a dark, deep hole said to be an underground passage to the nearby manor(庄园)of Lascaux. Squeezing through the entrance one by one, they soon saw wonderfully lifelike paintings of running horses, swimming deer, wounded wild oxen, and other beings—works of art that may be up to 20,000 years old.
The collection of paintings in Lascaux is among some 150 prehistoric sites dating from the Paleolithic period(旧石器时代)that have been documented in France's Vezere Valley. This corner of southwestern Europe seems to have been a hot spot for figurative art. The biggest discovery since Lascaux occurred in December 1994, when three cave explorers laid eyes on artworks that had not been seen since a rockslide 22,000 years ago closed off a large deep cave in southern France. Here, by unsteadily shining firelight, prehistoric artists drew outlines of cave lions, herds of rhinos(犀牛)and magnificent wild oxen, horses, cave bears. In all, the artists drew 442 animals over perhaps thousands of years, using nearly 400,000 square feet of cave surface as their canvas(画布). The site, now known as Chauvet-Pont-1'Arc Cave, is sometimes considered the Sistine Chapel of prehistory.
For decades scholars had theorized that art had advanced in slow stages from ancient scratchings to lively, naturalistic interpretation. Surely the delicate shading and elegant lines of Chauvet's masterworks placed them at the top of that progression. Then carbon dates came in, and prehistorians felt shocked. At some 36,000 years old—nearly twice as old as those in Lascaux—Chauvet's images represented not the peak of prehistoric art but its earliest known beginnings.
The search for the world's oldest cave paintings continues. On the Indonesian island of Sulawesi, for example, scientists found a large room of paintings of part-human, part-animal beings that are estimated to be 44,000 years old, older than any figurative art seen in Europe.
Scholars don't know if art was invented many times over or if it was a skill developed early in our evolution. What we do know is that artistic expression runs deep in our ancestry.

Is Student-loan Forgiveness Unforgivable?
Roughly 45 million Americans currently hold $1.6 trillion in student debt, with the average student-loan receiver owing between $20,000 and $25,000, according to the Federal Reserve. Among those actively making payments on their debt, the average monthly installment is between $200 and $300. And with 5.3 million more people unemployed than in February, right before the U.S. fell into the economic depression caused by pandemic (流行病), some people say that student-debt forgiveness could be beneficial to the economy.
“Student-debt cancellation feels like one of the most accessible executive actions to stimulate the economy at the moment,” says Suzanne Kahn, director of the Education. Kahn says the move would also help close the wealth gap between white Americans and people of color. Some 90% of Black students and 72% of Latino students take out loans for college versus just 66% of white students, according to an analysis from the Consumer Financial Protection Bureau.
But others argue that sweeping student-loan forgiveness doesn’t help the people who need aid most. Americans with college degrees, as a whole, have been less influenced by the economic effects of COVID-19 than their non-college-educated counterparts. Besides, they raise concerns that if the government wipes out current student loans, future college students may have a motivator to take on debts, hoping they will also be forgiven. Colleges may in turn tend to raise their prices further.
What’s clear, according to the both sides of the aisle (过道), is that economic crises worsen the problem of student debt. The last time the U.S. dipped into a recession, state governments cut their investments in colleges and universities—which, in turn, raised their tuition prices and forced students to take on ever larger loans.
In recent weeks, the government has walked a fine line on the issue, offering support for a bill calling for $10,000 worth of student-loan forgiveness but turning down anything close to a plan to issue $50,000 per borrower through executive action.
That’s not sustainable in the long run. It remains to be seen if the government can arrive at a political solution that is.

4 . The inside story of how a “band of misfits” saved Lego
When executives at toymaker Lego first learned that adults were buying large quantities of their interlocking plastic bricks and getting together to build Lego creations of their own, “they thought it was very strange,” says Paal Smith-Meyer.
Thanks to a handful of employees who worked to change attitudes inside the company, Lego is no longer embarrassed by its adult fans.
Today Lego is the world’s largest and most profitable toymaker. The Lego brick was named “Toy of the Century” in 1999, and in 2014 Time magazine crowned it the “Most Influential Toy of All Time”, ahead of Barbie, G.I. Joe, and the Easy Bake Oven.
The enthusiasm and buying power of Adult Fans of Lego — or AFOLs, as they’re known in the industry — played a major role in the company’s rise to the top.
Lego founder Ole Kirk Kristiansen always knew he wanted to market his products exclusively to kids. As the company grew over its first six decades, few imagined that its products could appeal as much to adults as to children.
Despite the benefits AFOLs brought to the brand, executives at the company’s corporate offices in Billund, Denmark had little interest in catering to adult customers. As fan mail and product ideas poured in from AFOLs around the world, the company posted its off-putting position: “We don’t accept unsolicited ideas.”
“Adult fans were often seen as a source of irritation,” says Jake McKee, a Lego executive from 2000 to 2006 who oversaw the company’s Global Community Development team.
A.But insiders say the road from “kids only” to “adults welcome” was a long, uphill climb. |
B.AFOLs are also organizing unofficial Lego fan conventions and networking in online user groups. |
C.Gone are the days when labels on Lego boxes stated that the contents were appropriate only for boys ages 7 to 12. |
D.Attitudes began to shift in the late 1990s and early 2000s when the once-invulnerable toymaker started to struggle. |
E.AFOLs were having a dramatic impact on Lego’s bottom line years before the company recognized their value. |
F.“Before the late 1990s, the company didn’t think their adult fans had value,” says Smith-Meyer, who held a variety of senior posts at Lego from 2000 to 2014. |
5 . Science may never know what memories play on the mind of the California sea hare, a foot-long marine snail, when it eats algae — a sea plant — in the tide pools of the Pacific coast.
But in a new study, researchers claim to have made headway in understanding the simplest kind of memory a creature might form.
David Glanzman, a neurobiologist at the University of California, believes the kinds of memories that trigger a defensive reaction in the snail are encoded not in the connections between brain cells, as many scientists would argue, but in RNA molecules (分子) that form part of an organism’s genetic machinery.
In an experiment to test the idea, Glanzman implanted wire into the tails of California sea hares, and gave them a series of electrical shocks. The procedure sensitized the animals so that when they were prodded (戳) in a fleshy spout called a siphon, they contracted their gills (鳃状呼吸器官) in a strong defensive action.
After sensitizing the sea snails, Glanzman extracted RNA from the animals and injected it into other sea snails to see what happened. He found the recipient sea snails became sensitized, suggesting the “memory” of the electrical shocks had been transplanted. When Glanzman repeated the experiment with RNA from sea snails that had been hooked up to wires but not shocked, the reaction behavior did not transfer.
Despite the result, the work has not found widespread acceptance. “Obviously further work needs to be carried out to determine whether these changes can happen without failure in a wide range of conditions,” said Prof Sherilynn Vann, who studies memory at Cardiff University. “While the sea hare is a fantastic model for studying basic neuroscience, we must be very cautious in drawing comparisons to human memory processes.”
Tomas Ryan, who studies memory at Trinity College Dublin, is firmly unconvinced. “It’s interesting, but I don’t think they’ve transferred a memory,” he said. “This work tells me that maybe the most basic behavioral responses involve some kind of switch in the animal and there is something in the liquid that Glanzman extracts that is hitting that switch.”
But Ryan added that different thinking about memory was badly needed: “In a field like this which is so full of accepted beliefs, we need as many new ideas as possible. This work takes us down an interesting road, but I have a huge amount of skepticism about it.”

Can Birdsong Make You Happier?
If you are able to step outside and hear many types of birds, you might also have a greater feeling of well-being. Two studies show that hearing diverse birdsongs may help increase our happiness.
One study was done by the researchers at California Polytechnic State University. The team studied the effects of birdsong on people walking through a park in the U.S. state of Colorado. Danielle Ferraro, who led the Cal Poly study, says that there could be an evolutionary reason why we like birdsong. The idea is that when we hear birdsong it could signal safety to us. There could be many other reasons too Ferraro states that in some areas around the world birdsong can also signal the arrival of spring and nice weather. Bird diversity, she adds, can also mean a healthy environment.
Similarly, scientists in Germany examined for the first time whether a diverse nature also increases human well-being across Europe. The researchers looked at the European Quality of Life Survey to study the connection between the different kinds of birds in their surroundings and life satisfaction. They looked at more than 26,000 adults from 26 European countries. “Europeans are particularly satisfied with their lives if their surroundings have a high species diversity,” explains the study’s lead author, Joel Methorst, a researcher at the Goethe University in Frankfurt. He and his team found that the happiest Europeans are those who can experience many different kinds of birds in their daily life, or who live in near-natural surroundings that are home to many species.
So, if birdsong is good for our mental health, how can we increase the different types of birdsongs we hear? Scientists also mentioned, “We would recommend planting native trees and flowers because we have a lot of pretty decorative plants in our cities. And they might look nice to us, but birds can’t necessarily use them. So, we think it important to have species that are native to the area to increase bird diversity.”

8 . Motivating Employees under Unfavourable Conditions
It is a great deal easier to motivate employees in a growing organization than a declining one. When organizations are expanding, promotional opportunities, pay rises, and the excitement of being associated with a dynamic organization create feelings of optimism. When an organization is shrinking, the best and mobile workers are likely to leave voluntarily.
Morale (士气) also suffers during decline. People fear they may be the next to be made unnecessary. Productivity often Suffers, as employees spend their time sharing rumours and providing one another with moral support rather than focusing on their jobs.
The literature on goal-setting theory suggests that managers should ensure that all employees have specific goals and receive comments on how well they are doing in those goals. Regardless of whether goals are achievable or well within management’s perceptions of the employee’s ability, if employees see them as unachievable they will reduce their effort.
Since employees have different needs, managers should use their knowledge of each employee to personalize the rewards over which they have control. Some of the more obvious rewards that managers allocate include pay, promotions and the opportunity to participate in goal-setting and decision-making.
A.There is enough evidence to support the motivational benefits that result from carefully matching people to jobs. |
B.For those whose jobs are secure, pay increases are rarely possible. |
C.High achievers are motivated by jobs that are high in independence and responsibility. |
D.Unfortunately, they are the ones the organization can least afford to lose—those with the highest skills and experience. |
E.The answer to that depends on perceptions of goal acceptance and the organization’s culture. |
F.Managers must be sure, therefore, that employees feel confident that their efforts can lead to performance goals. |
