5 . Since we’ve known about some cute animals, what about animals which aren’t so cute?
My favourite is a little creature called the Tasmanian devil. If you are out camping in Tasmania and come across one, the experience might scare you! Tasmanian devils hunt at night, so you won’t usually see them, but you may hear their loud cries when they are fighting or eating. The noise they make could wake the dead. Frightening! They are about the size of small dogs and look like rather large black rats. They also have a terrible smell! Their diet is mostly dead animals. Fortunately, despite their name, they are generally not violent towards people.
Australia also has some animals that many people have never heard of, for example, the duck-billed platypus. Is that some kind of bird? Not at all. While it may lay eggs in a nest like a bird, it’s really a primitive mammal, with a unique biology. Its eggs hatch after about ten days, and then the baby platypus nurses from its mother like all other mammals. Its nose looks like a duck’s bill, and it has feet like a duck’s so it can dive under the water, but it’s covered in hair. Do you know what’s really strange about a platypus? The platypus doesn’t use its senses of sight or smell to find food. It has a capacity to find food in the water by using electrical sensors in its bill. There are only a small handful of animals in the world that can do that!

6 . The number of universities has grown very fast in recent decades. Higher-education institutions across the world now employ 15 million researchers, up from 4 million in 1980. Governments are also happy to spend on higher education because it is supposed to produce scientific breakthroughs that can be available to all. In theory, therefore, universities should be an excellent source of productivity growth.
In practice, however, the productivity has slowed down during the last decades. In the 1950s and 1960s, workers’ output per hour across the rich world rose by 4% a year. But in the last decade, 1% a year was the norm. Even with the wave of innovation in artificial intelligence (AI), productivity growth remains weak — less than 1% a year, which is bad news for economic growth.
A new paper by Ashish Arora and his team suggests that universities’ rapid growth and the rich world’s slowdown productivity could be two sides of the same coin. The paper suggests that scientific breakthroughs from public institutions “caused little or no response from businesses” over a number of years. A scientist in a university lab might publish brilliant paper after brilliant paper. Often, however, this has no impact on corporations’ own patents, with life sciences being the exception. And this, in turn, points to a small impact on the overall productivity.
Why do companies struggle to use ideas produced by universities?
The paper says that, free from the demands of the market, researchers in university labs focus more on satisfying their curiosity than finding breakthroughs that will change the world or make money. “To some degree, such kind of research is not a bad thing; some breakthrough technologies, such as penicillin, were discovered almost by accident,” it writes, “But if everyone is doing that, the economy suffers.”
Perhaps, with time, universities and the business world will work together more tightly. Tougher competition could force businesses to beef up their internal research. In fact, researchers in companies’ labs, rather than universities, are driving the current AI innovations. At some point, governments will need to ask themselves hard questions. In a world of weak economic growth, huge spending on universities may come to seem an unjustifiable luxury.

7 . It’s one of life’s simple pleasures to take in the nice smell of fresh apples, or to bite into juicy tomatoes bursting with sweetness and flavor.
Having a look at the produce in your local grocery store, you might notice that a lot of products are wrapped in plastic. But many of them, like mushrooms, are about 70 to 90 percent water.
Take note of what foods you’re storing together. A lot of fruits and vegetables release ethylene, a colorless gas that occurs naturally in produce and is known as the “fruit ripening hormone”.
| A．Therefore, it is better to put them on the counter |
| B．The most well-known ethylene producers are bananas and apples |
| C．That’s why it’s important to keep these fruits and vegetables separate. |
| D．If you store them in a constantly wet environment, they will rot very fast |
| E．Cook your food incorrectly and you might end up throwing it into the trash can |
| F．But keeping them fresh once they reach your home is where the real challenge begins |
| G．For some fruits, how ripe they are when picked determines where they should be kept |
8 . Keith Payne realized he was poor for the first time when he was in the fourth grade. The awareness came to him when a new lunch lady in the cafeteria asked him to pay for his lunch.
“Previously, the lunch lady had just waved me on because I’d always been on free lunch,” he says. “But this new lady didn’t know how things worked, and it was the first time that I had been asked to pay for my lunch.”
It was an agonizing moment and all of a sudden, he realized why he got free lunch while many of his classmates were paying for their meals every day.
“It’s not like I was poorer the day after that than I was before. Nothing objective had changed. But because of that subjective awareness, I began constantly comparing myself with my classmates and felt really unhappy,” he says.
Keith Payne is now a social psychologist at the University of North Carolina and shares how the awareness of inequality affects the way that both our minds and our bodies respond.
“As we walk through the world, it is very natural for us to compare our lives with those of others. We think about ourselves in terms of being on a certain ladder (梯子) with some people above us and it can cause serious psychological consequences,” he says.
One is that it makes us more willing to seek out risks and engage in high-risk, high-reward sort of behaviors. It affects us in ways that are similar to physical threats.
“But I think there are wiser and less wise ways to make those social comparisons,” he says. “Upward social comparisons feel terrible, but they can be motivating. Downward social comparisons feel great, and yet they can be demotivating. So one of the things I recommend is that we can be more strategic in making upward and download social comparisons, Neither one is good in itself. It just depends on what your goal is.”

9 . The United Kingdom is hosting the AI Safety Summit, bringing politicians, computer scientists and big AI company leaders to a site chosen for its symbolism: Bletchley Park, the birthplace of computing and code-breaking (密码破译).
During World War II, a group of mathematicians, chess masters and other experts gathered at the Victorian country house 72 kilometers northwest of London to start a secret war against Nazi Germany. Their goal was to break a set of constantly changing codes produced by Nazi Germany’s Enigma machine. To do it, Bletchley Park’s wartime scientists — building on work done by Polish code-breakers — developed Colossus, the first programmable digital computer. Some historians say cracking the code helped shorten the war by up to two years.
“It has oversimplified its true contribution by describing Bletchley Park as a playground for Turing and other scientists.” said historian Chris Smith, author of The Hidden History of Bletchley Park. “Although it fits into the romantic idea that a group of smart men with a bit of wool and some yards of wire can win the war. In fact, almost 10,000 people worked at Bletchley Park during the war. Three quarters of them were women. It’s basically a factory... Twenty-four hours a day, seven days a week. When peace came, the code-breakers returned to civilian life and promised to keep secret about their wartime work. It was not until the 1970s that the work at Bletchley Park became widely known in Britain.”
In 1994, the site opened as a museum, after local historians banded together to prevent it from being pulled down to build a supermarket. It was restored to its 1940s appearance, complete with old typewriters, phones and cups—including the one tied to a heater in Hut 8, where Turing led the Enigma team.
