New research suggests that pandas may be at risk of dying out because they are too comfortable. Experts say too much happiness can stop the bears from searching for new mates. Environmentalists have long believed that building roads or homes near the bears may threaten their survival by "reducing or fragmenting their natural habitats", The Times reported. But the new research suggests that a "modest degree of discomfort and fragmentation" may actually help preserve panda populations. The research was conducted by scientists from Michigan State University. It concluded that pandas fail to wander off in search of new mates if they find their habitat too comfortable, resulting in a lack of vital genetic diversity. For their study — outlined in a paper in the journal Conservation Biology — the team looked at genetic diversity and spread among a Chinese panda population. The ideal level of perfectly livable habitat was found to be only 80% of an area, with the remainder either too harsh or too affected by human activity. The experts concluded that pandas should ideally "be happy enough to thrive, but not so content that they don't want to move around and find new mates". Their conclusions about what The Guardian described as this "sweet spot" are in line with the so-called Goldilocks principle: that there can be just the right amount of something. The concept has been applied to a wide range of disciplines, from developmental psychology to economics and engineering.

Claudio Sillero, a professor of conservation biology at Oxford University, told the newspaper that the new findings could have implications beyond panda conservation. "Most large animals that eat meat live in increasingly fragmented landscapes," said Sillero, who was not involved in the research. "It may well be that the messy nature of their relationship with human efforts induces more animals to scatter or travel further, and might result in greater genetic connectivity and enhanced population persistence." The most recent count of pandas found that there were more than 1,800 left in the wild, putting them on the list of vulnerable, but not endangered, species.【缺少答案,请补充】
With those born with natural talents, it feels as if they excel without really trying. But what about those of us who don't have a natural talent? We've been told all our lives that if you work hard, you too can succeed. But with the release of Angela Duckworth's Grit, we are given a new key to success. "As much as talent counts, effort counts twice," says Duckworth in Grit. She introduces a new concept that talent may be overrated, and if you want real success, what you need is grit, the perfect combination of passion and persistence. Even if you have natural talent, it's nothing without grit. Duckworth says grit is the difference between success and failure. A person who has grit is more likely to succeed than a person who does not. When we think about attaining success——whether it's landing that job or learning that new skill——our thoughts are immediately burdened by all the things we must first learn. If you want that new job, you have to learn the job skills, then the interview skills, then the dress part——and you must be perfect at all of them. Grit is different because it tells us that perfection isn't the goal. Grit lifts the unreasonable expectations off our shoulders. Grit tells us that the door is open wider than we first thought possible. Grit allows us to redefine our goals. Think about it: what's something you've always wanted to do, but gave up because you "don't have the skills for it"? What's something you love but aren't good at? The real workings of grit are to have sustainable passion and continue to try. Effort means more than your natural ability. Even if you haven't mastered a skill, grit tells you that you can still succeed if you can transform your passion into action. In a way, Duckworth is giving new hope to people who have shut the doors on their dreams. She is saying it is possible that you can accomplish anything. If at first you fail, then try one more time with grit.【缺少答案,请补充】
