Norman Garmezy, a developmental psychologist at the University of Minnesota, met thousands of children in his four decades of research. A nine-year-old boy in particular stuck with him. He has an alcoholic mother and an absent father. But each day he would walk in to school with a smile on his face. He wanted to make sure that "no one would feel pity for him and no one would know his mother's incompetence." The boy exhibited a quality Garmezy identified as "resilience."

Resilience presents a challenge for psychologists. People who are lucky enough to never experience any sort of adversity(逆境) won't know how resilient they are. It's only when they're faced with obstacles, stress, and other environmental threats that resilience, or the lack of it, comes out. Some give in and some conquer.

Garmezy's work opened the door to the study of the elements that could enable an individual's success despite the challenges they faced. His research indicated that some elements had to do with luck, but quite large set of elements was psychological, and had to do with how the children responded to the environment. The resilient children had what psychologists call an "internal locus of control (内控点)." They believed that they, and not their circumstances, affected their achievements. The resilient children saw themselves as the arrangers of their own fates.

George Bonanno has been studying resilience for years at Columbia University's Teachers College. He found that some people are far better than others at dealing with adversity. This difference might come from perception(认知) whether they think of an event as traumatic(创伤), or as an opportunity to learn and grow. "Stressful" or "traumatic" events themselves don't have much predictive power when it comes to life outcomes. "Exposure to potentially traumatic events does not predict later functioning," Bonanno said. "It's only predictive if there's a negative response." In other words, living through adversity doesn't guarantee that you'll suffer going forward.

The good news is that positive perception can be taught. "We can make ourselves more or less easily hurt by how we think about things," Bonanno said. In research at Columbia, the neuroscientist Kevin Ochsner has shown that teaching people to think of adversity in different ways—to reframe it in positive terms when the initial response is negative, or in a less emotional way when the initial response is emotionally "hot"—changes how they experience and react to the adversity.

Sulphur-crested cockatoos (葵花凤头鹦鹉) are common in western Australia, where they normally live in wooded areas. But as forests have been cut down, cockatoos have gotten used to living near people. Scientists report that people in Sydney, Australia are in a battle with these birds.

Last year, scientists at the Max Planck Institute reported that the cockatoos had learned how to open the covers of trash bins. That's not an easy job. The cockatoos must lift the heavy cover with their beaks (喙) and then walk along, pushing the cover up until it falls over.

When scientists first began studying the cockatoos in 2018, only three areas near Sydney had cover-opening cockatoos. A year and a half later, cockatoos in 44 different areas knew the trick. This time the scientists weren't just studying cockatoos. They were also studying humans.

The scientists spent weeks studying more than 3,200 trash bins in four different areas of Sydney. They wanted to see how many bins were protected and what methods were used.

In one area, over half the bins were protected. The most common way of protecting the bins was to put a brick or some other heavy objects on the cover. Some people put things like rubber snakes on the top of their bins. The scientists discovered that the humans were teaching each other tricks, too. In most neighborhoods, many people used the same cockatoo-stopping methods as their neighbors.

The researchers say it's like a race between humans and cockatoos to learn new ways of doing things. Now many cockatoos have learned how to push heavy items off the bins. As a result, humans have figured out ways to attach the items to the top of their bins. The scientists describe the situation as a "human-wildlife conflict". They expect these conflicts will become more common as humans take over more areas that used to be wild.

Sugar, protein and fat: if you're good at scanning those nutrition facts on food and drinks packages, it's thanks in large part to Burkey Belser, who is a well-known American graphic designer(平面设计师). But his work extended far beyond groceries. If you've noticed the Drug Facts box on over-the-counter medicines seems to be like the food label, that's because Belser designed it, as well. He also created the yellow Energy Guide box for home appliances.

Belser's passion for design started at a young age. He studied at the School of the Art Institute of Chicago and began a journey to become a graphic designer. His exceptional talent and skill quickly gained recognition, earning him numerous awards and accolades.

Belser's work is seen on billions of products. The nutrition fact box has been copied around the world. Creating the official food information box was a complicated process, with input from business groups and health advocates, along with Food and Drug Administration( FDA) experts. The design team worked through 35 versions before the product came out, and it was a huge success. " That is a masterpiece of information architecture, and quite a victory for social responsibility, " commented one Italian designer.

The nutrition label reflects Americans' evolving (演变) relationship with food shifting from an emphasis on vitamins and minerals to addressing obesity (肥胖) and related conditions. Belser's work not only made an impact within the industry but also played a crucial role in effectively communicating important messages to the public.

Speaking of his success, Belser said that luck had probably played a big role. But he added, " I'd say the willingness to work hard sets the stage to take advantage of whatever luck comes your way."
